Stack4.5Multi-Radio Dual ConnectivityNG-RAN supports Multi-Radio Dual Connectivity(MR-DC)operation whereby a UE in RRC_CONNECTED is configured to utilise radio resources provided by two distinct schedulers,located in two different NG-RAN nodes connected via a non-ideal backhaul,one providing NR access and the other one providing either E-UTRA or NR access. Further details of MR-DC operation can be found in TS37.340[21].5Physical Layer5.1Waveform,numerology and frame structureThe downlink transmission waveform is conventional OFDM using a cyclic prefix.The uplink transmission waveform is conventional OFDM using a cyclic prefix with a transform precoding function performing DFT spreading that can be disabled or enabled.Figure5.1-1:Transmitter block diagram for CP-OFDM with optional DFT-spreadingThe numerology is based on exponentially scalable sub-carrier spacing f=2µ×15kHz withµ={0,1,3,4}for PSS,SSS and PBCH andµ={0,1,2,3}for other channels.Normal CP is supported for all sub-carrier spacings,Extended CP is supported forµ=2.12consecutive sub-carriers form a Physical Resource Block(PRB).Up to275PRBs are supported on a carrier.Table5.1-1:Supported transmission numerologies.μ[kHz]f Cyclic prefix Supported for data Supported for synch∆μ=2⋅15015Normal Yes Yes130Normal Yes Yes260Normal,Extended Yes No3120Normal Yes Yes4240Normal No YesThe UE may be configured with one or more bandwidth parts on a given component carrier,of which only one can be active at a time,as described in subclauses7.8and6.10respectively.The active bandwidth part defines the UE's operating bandwidth within the cell's operating bandwidth.For initial access,and until the UE's configuration in a cell is received,initial bandwidth part detected from system information is used.Downlink and uplink transmissions are organized into frames with10ms duration,consisting of ten1ms subframes. Each frame is divided into two equally-sized half-frames of five subframes each.The slot duration is14symbols with Normal CP and12symbols with Extended CP,and scales in time as a function of the used sub-carrier spacing so that there is always an integer number of slots in a subframe.Timing Advance TA is used to adjust the uplink frame timing relative to the downlink frame timing.Figure5.1-2:Uplink-downlink timing relationOperation on both paired and unpaired spectrum is supported.5.2Downlink5.2.1Downlink transmission schemeA closed loop Demodulation Reference Signal(DMRS)based spatial multiplexing is supported for Physical Downlink Shared Channel(PDSCH).Up to8and12orthogonal DL DMRS ports are supported for type1and type2DMRS respectively.Up to8orthogonal DL DMRS ports per UE are supported for SU-MIMO and up to4orthogonal DL DMRS ports per UE are supported for MU-MIMO.The number of SU-MIMO code words is one for1-4layer transmissions and two for5-8layer transmissions.The DMRS and corresponding PDSCH are transmitted using the same precoding matrix and the UE does not need to know the precoding matrix to demodulate the transmission.The transmitter may use different precoder matrix for different parts of the transmission bandwidth,resulting in frequency selective precoding.The UE may also assume that the same precoding matrix is used across a set of Physical Resource Blocks(PRBs)denoted Precoding Resource Block Group(PRG).Transmission durations from2to14symbols in a slot is supported.Aggregation of multiple slots with Transport Block(TB)repetition is supported.5.2.2Physical-layer processing for physical downlink shared channelThe downlink physical-layer processing of transport channels consists of the following steps:-Transport block CRC attachment;。

Each frame is divided into two equally-sized half-frames of five subframes each.The slot duration is14symbols with Normal CP and12symbols with Extended CP,and scales in time as a function of the used sub-carrier spacing so that there is always an integer number of slots in a subframe. Timing Advance TA is used to adjust the uplink frame timing relative to the downlink frame timing.Figure5.1-2:Uplink-downlink timing relationOperation on both paired and unpaired spectrum is supported.5.2Downlink5.2.1Downlink transmission schemeA closed loop Demodulation Reference Signal(DMRS)based spatial multiplexing is supported for Physical Downlink Shared Channel(PDSCH).Up to8and12orthogonal DL DMRS ports are supported for type1and type2DMRS respectively.Up to8orthogonal DL DMRS ports per UE are supported for SU-MIMO and up to4orthogonal DL DMRS ports per UE are supported for MU-MIMO.The number of SU-MIMO code words is one for1-4layer transmissions and two for5-8layer transmissions.The DMRS and corresponding PDSCH are transmitted using the same precoding matrix and the UE does not need to know the precoding matrix to demodulate the transmission.The transmitter may use different precoder matrix for different parts of the transmission bandwidth,resulting in frequency selective precoding.The UE may also assume that the same precoding matrix is used across a set of Physical Resource Blocks(PRBs)denoted Precoding Resource Block Group(PRG).Transmission durations from2to14symbols in a slot is supported.Aggregation of multiple slots with Transport Block(TB)repetition is supported.5.2.2Physical-layer processing for physical downlink shared channelThe downlink physical-layer processing of transport channels consists of the following steps:-Transport block CRC attachment;-Code block segmentation and code block CRC attachment;-Channel coding:LDPC coding;-Physical-layer hybrid-ARQ processing;-Rate matching;-Scrambling;-Modulation:QPSK,16QAM,64QAM and256QAM;-Layer mapping;-Mapping to assigned resources and antenna ports.The UE may assume that at least one symbol with demodulation reference signal is present on each layer in which PDSCH is transmitted to a UE,and up to3additional DMRS can be configured by higher layers.Phase Tracking RS may be transmitted on additional symbols to aid receiver phase tracking.The DL-SCH physical layer model is described in TS38.202[20].5.2.3Physical downlink control channelsThe Physical Downlink Control Channel(PDCCH)can be used to schedule DL transmissions on PDSCH and UL transmissions on PUSCH,where the Downlink Control Information(DCI)on PDCCH includes: -Downlink assignments containing at least modulation and coding format,resource allocation,and hybrid-ARQ information related to DL-SCH;-Uplink scheduling grants containing at least modulation and coding format,resource allocation,and hybrid-ARQ information related to UL-SCH.In addition to scheduling,PDCCH can be used to for-Activation and deactivation of configured PUSCH transmission with configured grant;-Activation and deactivation of PDSCH semi-persistent transmission;。

WCDMA第三代无线通信系统核心网络介绍

一、前言与目前的手机系统GSM/GPRS比较起来，第三代无线通信系统的出现，将会带来更高的无线频宽与丰富的多媒体应用技术，在第三代无线通信系统中使用者在静止时可以提供2Mbit/sec的频宽，低速移动时可以提供384Kbits/sec的频宽，而在高速移动时则提供144Kbits/sec的频宽。

以这样的频宽来说，不只足以满足许多人对于语音传递的需求，甚至是各式各样的网络服务，都有极大的潜力无时无刻出现在使用者手机中。

第三代无线通信所包含的层面相当广泛，其中包括所会用到的技术以及在商业化过程中所面临的问题，如果以目前的架构来看，我们可以把整个系统大概分为一下五个部分：▪核心网络（Core Network）▪GSM、GPRS无线通信网络（GSM、GPRS Radio Access Network）▪WCDMA/UMTS无线通信网络（WCDMA/UMTS Radio Access Network）▪服务机制与安全（Service and Security）▪手持装置（Terminal Equipment）其中，核心网络所指的就是各系统业者用来连接各无线基地台与后端大众电话网络（PSTN）或是其他资料网络的Intranet。

通过核心网系统业者可以让手机用户的语音资料，经由业者的核心网络传递到目前通信的目的端。

因此在核心网的架构中，除了包含语音媒体资料的转换外，还包括了记录使用者资讯与计费机制的系统。

笔者认为，了解一个无线通信系统最好的方式就是由核心网着手。

因为如果一旦确实了解使用者的语音或是数据资料，是如何通过核心网来传送与处理的话，那整个系统的雏形将会很自然的在脑海中产生，进一步的再由无线通信的协议与界面来着手，在这样的学习过程中，可以在建立一个对系统的轮廓后，再逐一的把各个细节探讨完整，相信这将会是对初学无线通信的读者来说，最好的一个学习道路。

而GSM/GPRS与WCDMA/UMTS的无线通信网络，所指的就是手机与基地台间的无线通信界面与机制，这也是在认识无线通信系统中相当重要的一环。

外文翻译---宽带CDMA无线接入网的基本概念

中文3856字附录3：英文资料Basic Concepts of WCDMA Radio Access Network1. BackgroundThere has been a tremendous growth in wireless communication technology over the past decade. The significant increase in subscribers and traffic, new bandwidth consuming applications such as gaming, music down loading and video streaming will place new demands on capacity. The answer to the capacity demand is the provision of new spectrum and the development of a new technology - Wideband CDMA or hereinafter referred to as WCDMA. WCDMA was developed in order to create a global standard for real time multimedia services that ensured international roaming. With the support of ITU (International Telecommunication Union) a specific spectrum was allocated - 20Hz for 3G telecom systems. The work was later taken over by the 3GPP (3rd Generation Partnership Project), which is now the WCDMA specification body with delegates from all over the world.2. WCDMA a development from GSM and CDMANaturally there are a lot of differences between WCDMA and GSM systems, hut there are many similarities as well.The GSM Base Station Subsystem (BSS) and the WCDMA Radio Access Network (RAN) are both connected to the GSM core network for providing a radio connection to the handset. Hence, the technologies can share the same core network. Furthermore, both GSM BSS and WCDMA RAN systems are based on the principles of a cellular radio system. The GSM Base Station Controller (ESC) corresponds to the WCDMA Radio Network Controller (RNC). The GSM Radio Base Station (RBS) corresponds to the WCDMA RES, and the A -interface of GSM was the basis of the development of the Iu-interface of WCDMA, which mainly differs in the inclusion of the new services offered by WCDMA. The significant differences, apart from the lack of interface between the GSM BSCs and GSM Abis-interface to provide multi-vendoroperability, are more of a systemic matter. The GSM system uses TDMA (Time Division Multiple Access) technology with a lot of radio functionality based on managing the timeslots. The WCDMA system on the other hand uses CDMA, which means that both the hardware and the control functions are different. Examples of WCDMA-specific functions are fast power control and soft handover.Code Division Multiple Access and WCDMACode Division Multiple Access (CDMA) is a multiple access technology where the users are separated by unique codes, which means that all users can use the same frequency and transmit at the same time. With the fast development in signal processing,' it has become feasible to use the technology for wireless communication, also referred to as WCDMA and CDMA2000.In CDMA One and CDMA2000, a 1.25MHz wide radio signal is multiplied by a spreading signal (which is a pseudo-noise code sequence) with a higher rate than the data rate of the message. The resultant signal appears as seemingly random, but if the intended recipient has the right code, this process is reversed and the original signal is extracted. Using unique codes means that the same frequency is repeated in all cells. which is commonly referred to as a frequency re-use of 1.WCDMA is a step further in the CDMA technology. It uses a 5MHz wide radio signal and a chip rate of 3.84Mcps, which is about three times higher than the chip rate of CDMA2000. The main benefits of a wideband carrier with a higher chip rate are:●Support for higher bit rates●Higher spectrum efficiency thanks to improved trunking efficiency (i.e. a better statistical averaging)●Higher QoSFurther, experience from second-generation systems like GSM and CDMA One has enabled improvements to be incorporated in WCDMA. Focus has also been put on ensuring that as much as possible of WCDMA operators' investments in GSM equipment can be reused. Examples are the re-use and evolution of the core network, the focus on co-siting and the support of GSM handover. In order to use GSMhandover, the' subscribers need dual mode handsets.3. Radio Network FunctionalityFor optimal operation of a complete wireless system i.e. from handset to radio access network (RAN) several functions are needed to control the radio network and the many handsets using it. All functions described in this section, except' for Handover to GSM,' are essential and therefore necessary for a WCDMA system.3.1 Power controlThe power control regulates the transmit power of the terminal and base station, which results in less interference and allows more users on the same carrier. Transmit power regulation thus provides more capacity in the network. With a frequency re-use of 1, it is very important to have efficient power control in order to keep the interference at a minimum. For each subscriber service the aim is that the base station shall receive the same power level from all handsets in the cell regardless of distance from the base station. If the power level from one handset is higher than needed, the quality will be excessive, taking a disproportionate share of the resources and generating unnecessary interference with the other subscribers in the network.. On the other hand, if power levels are too low this will result in poor quality. In order to keep the received power at a suitable level, WCDMA has a fast power control that updates power levels 1500 times every second. By doing that the rapid change in the radio channel is handled. To ensure good performance, power control is implemented in both the up-link and the down-link, which means that both the output powers of the hanpset and the base station are frequently updated.Power control also gives rise to a phenomenon called "cell breathing". This is the trade-off between coverage and capacity, which means that the size of the cell varies depending on the traffic load. When the number of subscribers in the cell is low (low load), good quality can be achieved even at a long distance from the base station. On the other hand, when the number of users in the cell is high, the large number of subscribers generates a high interference level and subscribers have to get closer to the base station to achieve good quality.3.2 Soft and softer handoverWith soft and softer handover functionality the handset can communicate simultaneously with two or more cells in two or more base stations. This flexibility in keeping the connection open to more than one base station results in fewer lost calls, which is very important to the operator.To achieve good system performance with a frequency re-use of 1 and power control, soft and softer handover is required. Soft and softer handover enables the handset to maintain the continuity and quality of the connection while moving from. one cell to another.During soft handover, the handset will momentarily adjust its power to the base station that requires the smallest amount of transmit power and the preferred cell may change very rapidly. The difference between soft and softer handover is that during soft handover, the handset is connected to multiple cells at different base stations, while during softer handover, the handset is connected to multiple cells at the same base station. A drawback with soft handover is that it requires additional hardware resources on the network side, as the handset has multiple connections. In a well-designed radio network, 30%-40% of the users will be in soft or softer handover. As an example of soft or softer handover.3.3 Handover to GSM (inter-system handover)When WCDMA was standardized a key aspect was to ensure that existing investments could be re-used as much as possible. One example is handover between the new (WCDMA) network and the existing (GSM) network, which can be triggered by coverage, capacity or service requirements. Handover from WCDMA to GSM, for coverage reasons, is initially expected to be very important since operators are expected to deploy WCDMA gradually within their existing GSM network . When a subscriber moves out of the WCDMA coverage area, a handover to GSM has to be conducted in order to keep the connection.Handover between GSM and WCDMA can also have a positive effect on capacity through the possibility of load sharing. If for example the numbers of subscribers in the GSM network is close to the capacity limit in one area, handover ofsome subscribers to the WCDMA network can be performed.Another function that is related to inter-system handover is the compressed mode. When performing handover to GSM, measurements have to be made in order to identify the GSM cell to which the handover will be made. The compressed mode is used to create the measurement periods for the handset to make the required measurements.3.4 Inter-frequency handover (intra-system handover)The need for inter-frequency handover occurs in high capacity areas where multiple 5MHz WCDMA carriers are deployed. Inter-frequency handover, which is handover between WCDMA carriers on different frequencies, has many similarities with GSM handover, for example the compressed mode functionality.3.5 Channel type switchingIn WCDMA there are different types of channels that can be used to carry data in order to maximize the total traffic throughput. The two most basic ones are common channels and dedicated channels. Channel type switching functionality is used to move subscribers between the common and the dedicated channel, depending on how much information the subscriber needs to transmit. The dedicated channel is used when there is much information to transmit, such as a voice conversation or downloading a web page. It utilizes the radio resources efficiently as it supports both power control and soft handover.3.6 Admission controlAs there is a very clear trade-off between coverage and capacity in WCDMA systems, the admission control functionality is used to avoid system overload and to provide the planned coverage. When a new subscriber seeks access to the network, admission control estimates the network load and based on the new expected load, the subscriber is either admitted or blocked out. By this the operator can maximize the network usage within a set of network quality levels, i.e. levels depending on what kind of service/information the subscriber wants to use.3.7 Congestion controlEven though an efficient admission control is used, overload may still occur,which is mainly caused by subscribers moving from one area to another area. If overload occurs, four 'different actions can be taken. First, congestion control is activated and reduces the bit rate of non real-time applications, to resolve the overload. Second, if the reduced bit rate activity is not sufficient, the congestion control triggers the inter- or intra-frequency handover, which moves some subscribers to less loaded frequencies. Third, handover of some subscribers to GSM and fourth action is to discontinue connections, and thus protect the quality of the remaining connections. 3.8 SynchronizationOne of the basic requirements when WCDMA was standardized was to avoid dependence on external systems for accurate synchronization of base stations. This has been achieved by a mechanism, where the handset, when needed, measures the synchronization offset between the cells and reports this to the network. In addition, there is also an option to use an external source, such as GPS, for synchronizing the nodes, i.e. to always provide the best solution both asynchronous and synchronous nodes are supported.4. Basic architecture concepts/ System overview4.1 Radio Access Network (RAN) ArchitectureThe main purpose of the WCDMA Radio Access Network is to provide a connection between the handset and the core network and to isolate all the radio issues from the core network. The advantage is one core network supporting multiple access technologies.The WCDMA Radio Access Network consists of two types of nodes:Radio Base Station (Node B)The Radio Base Station handles the radio transmission and reception to/from the handset over the radio interface (Iu). It is controlled from the Radio Network Controller via the Iub interface. One Radio Base Station can handle one or more cells.Radio Network Controller (RNC)The Radio Network Controller is the node that controls all WCDMA Radio Access Network functions. It connects the WCDMA Radio Access Network to thecore network via the Iu interface. There are two distinct roles for the RNC, to serve and to control. The Serving RNC has overall control of the handset that is connected to WCDMA Radio Access Network. It controls the connection on the Iu interface for the handset and it terminates several protocols in the contact between the handset and the WCDMA Radio Access Network.The Controlling RNC has the overall control of a particular set of cells, and their associated base stations. When a handset must use resources in a cell not controlled by its Serving RNC, the Serving RNC must ask the Controlling RNC for those resources. This request is made via the Iur interface, which connects the RNCs with each other. In this case, the Controlling RNC is also said to be a Drift RNC for this particular handset. This kind of operation is primarily needed to be able to provide soft handover throughout the network.Radio Access Bearers (RAB)The main service offered by WCDMA RAN is the Radio Access Bearer (RAB).A RAB is needed to establish a call connection between the handset and the base station. Its characteristics ate determined by certain Quality of Service (QoS) parameters, such as bit rate and delay, and are different depending on what kind of service/information to be transported.The RAB carries the subscriber data between the handset and the core network. It is composed of one or more Radio Access Bearers between the handset and the Serving RNC, and one Iu bearer between the Serving RNC and the core network. 3GPP has defined four different quality classes of Radio Access Bearers:●Conversational (used for e.g. voice telephony) - low delay, strict ordering●Streaming (used for e.g. watching a video) - moderate delay, strict ordering●Interactive (used for e.g. web surfing) - moderate delay●Background (used for e.g. me transfer) - no delay4.2 Transport in WCDMA Radio Access NetworkThe WCDMA Radio Access Network nodes communicate with each other over a transport network. The 3GPP specification provides a very clear, split between radio related (WCDMA)functionality and the transport technology, meaning that there is noparticular bias to any technology. The transport network is initially based on ATM, but IP will soon be included as an option.附录4：英文资料译文宽带CDMA无线接入网的基本概念一、背景过去十年，无线通信技术有了巨大发展，用户量的显著增加，使得诸如游戏、音乐下载和视频流量有了新的容量需求。

5g 重定向标准

5g 重定向标准
5G重定向标准是指在5G网络中，当用户处于移动状态时，实现无缝的连接切换和服务传递的技术标准。

以下是一些与5G重定向相关的标准：
1. 3GPP (第三代合作伙伴计划)标准：3GPP是负责制定5G通信标准的国际组织。

它定义了5G网络中的核心功能和协议，包括重定向过程、手over过程等。

2. NR (New Radio)标准：NR是5G无线接入技术的名称，它提供了高速、低延迟和大容量的通信能力。

NR标准中包含了对重定向的具体规范。

3. NG-RAN (Next Generation Radio Access Network)标准：NG-RAN定义了5G网络中的无线接入部分，并包含了多个基站间的切换和重定向机制。

4. N2接口标准：N2接口是在5G网络中用于控制平面和用户平面之间的接口。

它涉及到重定向消息的传递和处理。

需要注意的是，5G重定向标准是不断发展和演进的，随
着技术的进步和应用场景的丰富，相关标准也会进行更新和优化。

因此，以上列举的标准只是其中的一部分，具体的标准和规范可以在相关组织和标准化机构的文档中找到。
