具体实施方式detailed description
下面结合附图及具体实施例对本申请再作进一步详细的说明。The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
实施例一、 Embodiment 1
本申请提供了一种实体管理方法,如图2a所示,所述方法包括:The application provides an entity management method, as shown in FIG. 2a, the method includes:
步骤2011:快速控制MAC实体确定针对所述至少一个实时MAC实体的调度指令;Step 2011: The fast control MAC entity determines a scheduling instruction for the at least one real-time MAC entity;
步骤2012:所述快速控制MAC实体向所述至少一个实时MAC实体发送所述调度指令。Step 2012: The fast control MAC entity sends the scheduling instruction to the at least one real-time MAC entity.
本申请针对5G接入网络的分布式架构和空口特性需求,以及目前MAC协议实体功能的局限性问题,提出了一种具有空口快速信令能力的总分式MAC方案,该方案在兼容已有MAC协议栈功能的基础增加了新的处理功能。This application proposes a total fractional MAC scheme with air interface fast signaling capability for the distributed architecture and air interface feature requirements of the 5G access network and the limitations of the current MAC protocol entity function. The basis of the MAC protocol stack functionality adds new processing capabilities.
MAC协议实体功能总方案如图3a所示。本实施例中将MAC协议 实体功能划分为两个功能模块:快速控制(FC)-MAC实体和实时(RT)-MAC实体。The overall scheme of the MAC protocol entity function is shown in Figure 3a. MAC protocol in this embodiment The entity function is divided into two functional modules: a fast control (FC)-MAC entity and a real-time (RT)-MAC entity.
其中,FC-MAC分为快速控制功能(Fast Signaling Control)、流量控制功能(Flow Control)和RT-MAC调度控制功能(RT-MAC Control)三个功能。RT-MAC即为目前现有或者目前传统MAC协议实体功能以及其后继演进功能。Among them, FC-MAC is divided into three functions: Fast Signaling Control, Flow Control, and RT-MAC Control. RT-MAC is the current or current traditional MAC protocol entity function and its subsequent evolution function.
为了保证协议栈的兼容性,把包括演进功能在内的传统的MAC功能统一定义成RT-MAC,完成面向小区内用户调度、小区内无线资源分配、小区内用户和无线资源相应过程的控制,RT-MAC功能只聚焦于小区内的相应的MAC功能。In order to ensure the compatibility of the protocol stack, the traditional MAC function including the evolution function is uniformly defined as an RT-MAC, and the control for the intra-cell user scheduling, the intra-cell radio resource allocation, the intra-cell user and the radio resource corresponding process is completed. The RT-MAC function only focuses on the corresponding MAC function within the cell.
FC-MAC功能为新增MAC功能,所述快速信令(RC)-MAC实体与RT-MAC实体之间的关系为:全部MAC实体由FC MAC实体以及RT MAC实体共同组成;并且FC MAC实体以及RT MAC实体之间不具备交集。FC-MAC不改变RT-MAC的基本功能,以保证总分式的MAC方案对原有MAC的完全兼容性。The FC-MAC function is a new MAC function, and the relationship between the fast signaling (RC)-MAC entity and the RT-MAC entity is: all MAC entities are jointly composed of an FC MAC entity and an RT MAC entity; and the FC MAC entity And there is no intersection between RT MAC entities. The FC-MAC does not change the basic functions of the RT-MAC to ensure full compatibility of the MAC scheme of the total fraction with the original MAC.
具体来说,如图3a所示,FC-MAC主要包括三个大功能:承担的快速控制功能,即传统上是通过RRC信令进行交互的控制过程,下沉到MAC通过空口调度进行快速控制功能;对用户数据链路的RB流控功能,通过用户的空口信息,控制PDCP/DRC/RLC上数据的分配数量;对RT-MAC的调度控制过程(不包括信令控制功能),该功能重点完成对RT-MAC的调度以及为了完成调度而需要的非信令式的控制功能。Specifically, as shown in FIG. 3a, the FC-MAC mainly includes three major functions: a fast control function that is assumed, that is, a control process that is traditionally performed through RRC signaling, and sinks to the MAC to perform fast control through air interface scheduling. Function; RB flow control function for the user data link, controlling the number of data allocated on the PDCP/DRC/RLC through the air interface information of the user; scheduling control process for the RT-MAC (excluding the signaling control function), the function Emphasis is placed on the scheduling of RT-MACs and the non-signaling control functions required to complete the scheduling.
下面结合图4a、图5a、图5b和图5c,具体说明FC MAC实体的多种功能及其实现:The various functions of the FC MAC entity and their implementation are specifically described below with reference to FIG. 4a, FIG. 5a, FIG. 5b and FIG. 5c:
第一种、The first,
所述快速控制MAC实体确定针对所述至少一个实时MAC实体的调度 指令,至少包括:Determining, by the fast control MAC entity, scheduling for the at least one real-time MAC entity Instructions, including at least:
所述快速控制MAC实体从无线资源控制RRC实体获取到RRC信令的内容;所述快速控制MAC实体基于所述RRC信令的内容,生成针对所述至少一个实时MAC实体的调度指令。The fast control MAC entity acquires content of the RRC signaling from the radio resource control RRC entity; the fast control MAC entity generates a scheduling instruction for the at least one real-time MAC entity based on the content of the RRC signaling.
或者,所述快速控制MAC实体,还可以进一步的根据用户行为(比如用户的信道质量、用户的能力,用户需要的业务特征)产生相应的空口控制,进而结合空口控制生成调度指令。Alternatively, the fast control MAC entity may further generate corresponding air interface control according to user behavior (such as the channel quality of the user, the capability of the user, and the service feature required by the user), and then generate a scheduling instruction in combination with the air interface control.
其中,所述生成针对所述至少一个实时MAC实体的调度指令,可以包括:所述快速控制MAC实体通过预设的特殊的PDCCH或者定义的MAC控制元素(CE,Control Element)进行调度指令的封装。The generating the scheduling instruction for the at least one real-time MAC entity may include: the fast control MAC entity encapsulating the scheduling instruction by using a preset special PDCCH or a defined MAC control element (CE, Control Element) .
具体来说,比如,参见图4a,所述快速控制MAC实体承接RRC协议信令功能,包括:原有RRC协议实体的信令功能需要实现快速控制而下沉到MAC的功能。Specifically, for example, referring to FIG. 4a, the fast control MAC entity performs the RRC protocol signaling function, including: the signaling function of the original RRC protocol entity needs to implement fast control and sink to the MAC.
其中,所述RRC信令包括但不限于:空口切换信令和/或无线链路重配置信令,以及其他针对物理链路的信令控制,比如空口格式的改变、空口物理信道的改变。The RRC signaling includes, but is not limited to, air interface switching signaling and/or radio link reconfiguration signaling, and other signaling control for the physical link, such as a change of the air interface format and a change of the air interface physical channel.
也就是说,通过将空口切换的相关信令下沉到快速控制MAC实体来实现,原有通过RRC空口信令进行控制,现在可以通过FC-MAC发送特殊的PDCCH或者定义的MAC控制元素(CE,Control Element)进行快速控制。That is to say, by sinking the relevant signaling of the air interface handover to the fast control MAC entity, the original control by RRC air interface signaling can now send a special PDCCH or a defined MAC control element (CE) through the FC-MAC. , Control Element) for quick control.
再比如为了实现空口的无缝(Seamless)切换,通过FC-MAC发送链路控制信令取代原有RRC协议实体的无线链路重配置信令。For example, in order to implement seamless switching of the air interface, the FC-MAC sends link control signaling to replace the radio link reconfiguration signaling of the original RRC protocol entity.
进一步地,结合图5a,对关于RRC下沉的信令过程,也就是将RRC实体处获取到的信息进行包装,并且生成调度指令发送给RT-MAC实体的处理流程进行说明: Further, in conjunction with FIG. 5a, a description is given of a signaling procedure for RRC sinking, that is, packaging the information acquired at the RRC entity, and generating a scheduling instruction to be sent to the RT-MAC entity.
步骤51-1、基站(Base Station)的RRC实体根据相应算法判决,需要产生相应的信令,根据该信令生成发送给Base Station的FC-MAC发送控制信息(Control Indication),Control Indication中只包含具体的信令内部的具体内容,把该信令的内容刻画清楚即可,不需要转换成RRC空口信令的格式(ASN.1格式)二进制流。其中,生成的信令可以为需要进行下沉的指定信令,比如,上述示例的空口切换的相关信令,以及无缝切换的相关信令,另外,具体的上述信令仅为示例,实际处理过程中,可以根据实际需要进行设置。Step 51-1: The RRC entity of the base station (Base Station) decides according to the corresponding algorithm, and needs to generate corresponding signaling, and generates FC-MAC transmission control information (Control Indication) sent to the Base Station according to the signaling, and only the Control Indication in the Control Indication The specific content of the specific signaling is included, and the content of the signaling is clearly defined, and the binary stream of the format (ASN.1 format) that does not need to be converted into RRC air interface signaling is not required.

获取到自身管理的至少一个实时MAC实体中的处理负荷、对应的空间覆盖,以及获取到至少一个终端设备上报的空口质量、邻区空口质量、移动方向等等各种空口特征参数、小区特征参数和用户特征参数。Acquiring processing load, corresponding spatial coverage in at least one real-time MAC entity that is managed by itself, and acquiring various air interface feature parameters, cell feature parameters, such as air interface quality, neighboring air interface quality, and moving direction reported by at least one terminal device And user feature parameters.
为所述终端设备分配目标实时MAC实体作为第一分配结果可以为:为上述至少一个终端设备中的每一个终端设备均分配对应的目标实时MAC实体,将分配的目标实时MAC实体作为上述每一个终端设备对应的第一分配结果。Assigning the target real-time MAC entity to the terminal device as the first allocation result may be: assigning a corresponding target real-time MAC entity to each of the at least one terminal device, and using the allocated target real-time MAC entity as each of the foregoing The first allocation result corresponding to the terminal device.
可以理解的是,本功能中,至少一个终端设备可以为多个;进一步地,其中,每一个终端设备可以均为已经选定其所要接入的目标小区的终端设备;也就是说,本功能中主要针对了对小区内的至少一个终端设备选取对应的目标实时MAC实体。It can be understood that, in this function, at least one terminal device may be multiple; further, each terminal device may be a terminal device that has selected a target cell to which it is to be accessed; that is, this function The method is mainly for selecting a corresponding target real-time MAC entity for at least one terminal device in the cell.

Further, if the load of an RT-MAC entity is large, it can be allocated a service type for carrying a small load demand. Therefore, it is possible to select a reasonable number of users or user service types for each RT-MAC (to ensure the QoS requirements of the service).
上述第二种功能中快速控制MAC实体与实时MAC实体之间的连接关系可以参见图4a。通过上述功能能够实现由快速控制MAC进行用户也就是终端设备和实时MAC实体之间的双向动态实时映射的控制。For the connection between the MAC entity and the real-time MAC entity, the connection between the MAC function and the real-time MAC entity can be seen in Figure 4a.

MAC协议实体功能总方案如图3a所示,本实施例中将MAC协议实体功能划分为两个功能模块:快速控制(FC)-MAC实体和实时(RT)-MAC实体。其中,FC-MAC分为快速控制功能(Fast Signaling Control)和RT-MAC调度控制功能(RT-MAC Control)两个功能。RT-MAC即为目前现有或者目前传统MAC协议实体功能。The overall scheme of the MAC protocol entity function is shown in FIG. 3a. In this embodiment, the MAC protocol entity function is divided into two functional modules: a fast control (FC)-MAC entity and a real-time (RT)-MAC entity. Among them, FC-MAC is divided into two functions: Fast Signaling Control (RT) and RT-MAC Control (RT-MAC Control). RT-MAC is the current or current traditional MAC protocol entity function.

According to the overall control of the RRC signaling (the RRC through the signaling configuration function optional set, the MAC selects a specific function for the PDCP/DDR/RLC in the function set), the PDCP/DDR/RLC function is dynamically fine-tuned.
比如,可以包括:是否需要DDR功能,即DDR是否可以透传;PDCP/RLC是否启用集中-分布式模式等。For example, it may include: whether a DDR function is required, that is, whether the DDR can be transparently transmitted; whether the PDCP/RLC enables the centralized-distributed mode or the like.
其中,DDR功能模块,主要用于完成从PDCP接收的数据向RLCcenter/RLCremote上的分发、从RLCcenter/RLCremote接收重组后按序递交给PDCP和RLCcenter/RLCremote的控制;The DDR function module is mainly used for completing the distribution of data received from the PDCP to the RLCcenter/RLCremote, and receiving the reorganization from the RLCcenter/RLCremote, and then submitting the control to the PDCP and the RLCcenter/RLCremote in sequence;
RLC实体中则可以包括有RLCcenter和RLCremote功能实体,且上述两个功能实体为互斥出现(Mutually-exclusive RLC Entity),即存在RLCcenter时,不会存在RLCremote,同理,存在RLCremote时,不会存在RLCcenter。RLCcenter/RLCremote。The RLC entity may include the RLCcenter and the RLCremote functional entity, and the two functional entities are Mutually-exclusive RLC Entity, that is, when the RLCcenter exists, the RLCremote does not exist. Similarly, when the RLCremote exists, There is RLCcenter. RLCcenter/RLCremote.
需要理解的是,将这种功能下沉到快速控制MAC实体中来进行, 使得针对PDCP、DDR以及RLC等实体的控制能够更加快速。It should be understood that sinking this function into the fast control MAC entity, Controls for entities such as PDCP, DDR, and RLC can be made faster.
其次,下面再针对实现快速控制MAC实体对RRS中的至少一个实时MAC实体进行控制进行说明:Secondly, the following describes the implementation of the fast control MAC entity to control at least one real-time MAC entity in the RRS:
在现有LTE架构中,MAC的功能可以参见图6a,可以看出,在LTE架构中,目前由MAC进行无线资源管理、信道质量管理以及PDU控制等功能,并且进一步地基于上述几种管理功能确定终端设备的小区分配,然后对每一个终端设备进行调度。本实施例中基于上述架构进一步对MAC的功能进行了划分,并且为MAC增加了快速控制MAC功能进行总体处理,如此,使得本实施例提供的方案能够在MAC层就完成对至少一个MAC实体的调度以及控制,进而保证了快速完成空口信令的下发,提升了整体架构的处理速度。In the existing LTE architecture, the function of the MAC can be seen in Figure 6a. It can be seen that in the LTE architecture, the functions of radio resource management, channel quality management, and PDU control are currently performed by the MAC, and further based on the foregoing management functions. The cell allocation of the terminal device is determined, and then each terminal device is scheduled.

对上述功能进一步进行说明: Further explain the above functions:
所述方法还包括:The method further includes:

具体来说,针对终端设备的无线资源管理功能,用于完成UE的历史空口资源的占用管理和当前空口资源的使用管理。该模块管理两个方面的资源,一个是RRC配置的半静态的UE专用无线资源,比如SRS、PUCCH等;一个是MAC每个TTI动态分配的空口资源,比如PRB、PDCCH等,用作UE信道的平滑测量。Specifically, the radio resource management function for the terminal device is used to complete occupation management of the historical air interface resource of the UE and use management of the current air interface resource. The module manages two aspects of resources, one is a semi-static UE-dedicated radio resource configured by RRC, such as SRS, PUCCH, and the like; and the other is an air interface resource dynamically allocated by each TTI of the MAC, such as PRB, PDCCH, etc., used as a UE channel.

The module receives the channel measurement parameters of the physical layer and performs calculation according to a certain algorithm, and is used as the channel quality monitoring of the UE in each corresponding cell. Each time the MAC schedules the UE, the radio resource allocation is performed according to the channel quality of the UE.
小区间的无线质量管理功能,用于管理每个cell的无线空口质量,为cell间的协作提供参数支撑。该功能模块根据cell内每个UE的信道质量采用相关算法,计算每个cell的平均空口质量、相关干扰等,以确定cell的负荷能力。在MAC调度每个cell可以支撑的具体UE时需要根据cell的无线质量进行抉择。The wireless quality management function of the small interval is used to manage the quality of the wireless air interface of each cell and provide parameter support for the cooperation between the cells. The function module uses a correlation algorithm according to the channel quality of each UE in the cell to calculate the average air interface quality and related interference of each cell to determine the load capacity of the cell. When the MAC schedules a specific UE that each cell can support, it needs to make a decision according to the radio quality of the cell.
进一步地,基于上述几种功能,所述通过快速控制MAC实体生成控制 信令,包括:Further, based on the above several functions, the generating control by the MAC entity is controlled quickly Signaling, including:

The function module completes the set of cells available to each UE according to various air interface qualities, that is, completes mapping of the logical channel to the cell of the UE.
通过针对终端设备的PDU控制功能,完成UE传输的packets在符合MAC指示的大小时,确保不对RLC产生任何影响,包括RLC的SN号不能出现剧烈的跳变、给RLC带来除去传统功能外的新增功能等。下行FC-MAC在每个cell内完成UE的调度后确定UE在该cell内发送的SDU的大小;然后,通过PDU Controller从RLC处获取packet,PDU Controller根据相应的算法确保多个cell发送的PDU不对RLC产生影响。Through the PDU control function for the terminal device, when the packets transmitted by the UE meet the size indicated by the MAC, it is ensured that the RLC does not have any influence, and the SN number of the RLC cannot be violently changed, and the RLC is removed from the traditional function. New features, etc. After the downlink FC-MAC completes the scheduling of the UE in each cell, the size of the SDU sent by the UE in the cell is determined.

下行CCCH功能:可以根据每个UE在每个cell上的信道质量,选择每个UE最合适的空口信道,所以CCCH需要经过cell和UE两级调度。The downlink CCCH function: The most suitable air interface channel for each UE can be selected according to the channel quality of each UE on each cell, so the CCCH needs to be scheduled by the cell and the UE.
PCH功能:可以根据每个UE在每个cell上的信道质量,选择每个UE最合适的空口信道,并组合成合适的PCH在空口发送。所以PCH需要经过cell和UE两级调度。PCH function: According to the channel quality of each UE on each cell, the most suitable air interface channel of each UE can be selected and combined into an appropriate PCH to be sent in the air interface. Therefore, the PCH needs to be scheduled by the cell and the UE.

具体的,所述快速控制MAC实体为所述终端设备选取空口承载方式,的确定方式可以为:通过RT-MAC和物理层(PHY)上报的各个终端设备的各种测量信息,通过所述各个终端设备的测量信息准确感知到各个终端设备在空口的传输资源需求;获取到RRC实体的信令的内容;结合所述各个终端设备在空口的传输资源需求以及RRC实体的信令的内容,为每一个终端设备选择空口承载方式。Specifically, the fast control MAC entity selects an air interface bearer mode for the terminal device, and the determining manner may be: using various measurement information of each terminal device reported by the RT-MAC and the physical layer (PHY), The measurement information of the terminal device accurately senses the transmission resource requirement of each terminal device in the air interface; acquires the content of the signaling of the RRC entity; combines the transmission resource requirements of the air interface of each terminal device with the signaling content of the RRC entity, Each terminal device selects an air interface bearer mode.
其中,获取RRC实体的信令的内容,可以为RRC实体仍然执行为终端设备进行空口承载方式的分配,但是不再生成具体的信令,而将空口承载方式发送给快速控制MAC实体,最终使得快速控制MAC实体基于器分配的空口承载方式生成调度指令。其具体的实现流程可以参见图6a,这里不再进行赘述。The content of the signaling of the RRC entity is obtained, and the RRC entity can still perform the allocation of the air interface bearer mode for the terminal device, but the specific signaling is not generated, but the air interface bearer mode is sent to the fast control MAC entity, and finally The fast control MAC entity generates a scheduling instruction based on the air interface bearer mode allocated by the device. The specific implementation process can be seen in Figure 6a, and details are not described herein.
其中,选取的空口承载方式可以使用OFDM+CDMA的方式承载用户的数据和信令,或者使用非正交的物理层技术启动某些用户的快速数据收发。本实施例中不对终端设备的空口承载方式进行穷举。The selected air interface bearer mode may use the OFDM+CDMA mode to carry user data and signaling, or use non-orthogonal physical layer technology to enable fast data transmission and reception of some users. In this embodiment, the air interface carrying mode of the terminal device is not exhaustive.
所述通过快速控制MAC实体生成控制信令,包括:The generating control signaling by using the fast control MAC entity includes:
为所述至少一个实时MAC实体中每一个实时MAC实体确定数据传输类型;其中,所述数据传输类型包括控制面的数据传输、和/或、用户面的数据传输;Determining, for each of the at least one real-time MAC entity, a data transmission type; wherein the data transmission type comprises a data transmission of a control plane, and/or a data transmission of a user plane;
基于所述至少一个实时MAC实体对应的数据传输类型,生成所述控制指令。Generating the control instruction based on a data transmission type corresponding to the at least one real-time MAC entity.
具体的,RT-MAC实时功能的动态调度控制。根据RRC信令的总体性控制(RRC通过信令配置功能可选集合,MAC在该功能集合中给RT-MAC选择具体的功能),对RT-MAC功能进行调度控制,包括是否只进行控制面(Control Plane)或者用户面(User Plane)相应数据的收发,还是同时可以进行Control Plane和User Plane数据的收发。 Specifically, the dynamic scheduling control of the RT-MAC real-time function. According to the overall control of the RRC signaling (the RRC is configured by the signaling configuration function, the MAC selects a specific function for the RT-MAC in the function set), and performs scheduling control on the RT-MAC function, including whether only the control plane is performed. (Control Plane) or user plane (User Plane) corresponding data transmission and reception, or control Plane and User Plane data can be sent and received at the same time.
在上述针对下行信息的生成以及传输的基础上,本实施例还可以针对上行信令的传输以及处理进行相应说明,具体的,所述方法还包括:On the basis of the foregoing generation and transmission of the downlink information, the embodiment may further describe the transmission and processing of the uplink signaling. Specifically, the method further includes:
通过设置于RCC的快速控制MAC实体从所述至少一个实时MAC实体获取到至少一个终端设备上传的上行信令,并对所述上行信令进行解析以及处理。Acquiring, by the fast control MAC entity set in the RCC, the uplink signaling uploaded by the at least one terminal device from the at least one real-time MAC entity, and parsing and processing the uplink signaling.
传统的MAC可以参见图6c,5G的上行MAC具备的功能。本实施例的上行总分式MAC的结构以及功能,参见图6b,对于上行MAC而言,FC-MAC的针对上行信令的处理功能与下行相互对应,也就是说,同样包括Scheduling/Priority Handling among Cells for UE、Multiplexing UEs in Cell、PDU Controller、Scheduling/Priority Handling in Cell、Multiplexing in CC等功能。RT-MAC包括Scheduling/Priority Handling、Multiplexing和HARQ等功能。需要理解的是,这些上行信令的处理功能,均基于接收到终端设备侧在下行信令的控制基础之上主动上报的上行信令,或者是针对下行信令的反馈信息,而对于这些上行信令的处理与下行信令的生成可以互为可逆处理过程。The traditional MAC can be seen in Figure 6c, the function of the 5G upstream MAC. For the structure and function of the uplink total fractional MAC in this embodiment, refer to FIG. 6b. For the uplink MAC, the processing function of the FC-MAC for the uplink signaling corresponds to the downlink, that is, the Scheduling/Priority Handling is also included. Among Cells for UE, Multiplexed UEs in Cell, PDU Controller, Scheduling/Priority Handling in Cell, Multiplex in CC, etc. RT-MAC includes functions such as Scheduling/Priority Handling, Multiplexing, and HARQ. It should be understood that the processing functions of the uplink signaling are based on receiving uplink signaling that is actively reported by the terminal device on the basis of the downlink signaling control, or feedback information for downlink signaling, and for these uplinks. The processing of signaling and the generation of downlink signaling may be mutually reversible processing.
UE的上行PDU Controller模块完成UE传输的packets在符合MAC指示的大小(Scheduling/Priority Handling among Cells for UE和Unicast Scheduling/Priority Handling功能模块提供)时,确保不对RLC产生任何影响,包括RLC的SN号不能出现剧烈的跳变、给RLC带来除去传统功能外的新增功能等。上行MAC收到的MAC PDU经过MAC解包功能得到SDU后,通过PDU Controller发送RLC进行后继的处理,PDU Controller根据相应的算法确保多个cell发送的PDU不对RLC产生影响。The packets of the UE's uplink PDU Controller module complete the UE transmission are guaranteed to have no impact on the RLC when the packets indicated by the MAC (Scheduling/Priority Handling among Cells for UE and Unicast Scheduling/Priority Handling function modules are provided), including the SN number of the RLC. There can be no violent jumps, and RLC brings new functions beyond the traditional functions. After the MAC PDU received by the uplink MAC obtains the SDU through the MAC unpacking function, the PDU Controller sends the RLC for subsequent processing. The PDU Controller ensures that the PDUs sent by multiple cells do not affect the RLC according to the corresponding algorithm.
Scheduling/Priority Handling among Cells for UE根据网络侧配置UE的多个cell的可选择通道,完成本次UE使用的cells分配,比如多个cell的每个cell上网络侧都给UE配置了周期的SR,UE可以根据空 口信道质量,选择合适的cell发送SR。还比如SPS分配的资源、周期上报的CQI等,从而完成UE的逻辑信道到cell的映射。The Scheduling/Priority Handling among Cells for the UE configures the cells allocated by the UE according to the selected channels of the multiple cells of the UE on the network side. For example, the network side of each cell of the multiple cells configures the periodic SR for the UE. , UE can be empty Channel channel quality, select the appropriate cell to send the SR. For example, the resource allocated by the SPS, the CQI reported periodically, and the like, thereby completing the mapping of the logical channel to the cell of the UE.
Multiplexing UE in Cellm完成每个cell可以发送的RB,即在此TTI内,该UE在该cell内发送的数据内容。Multiplexing UE in Cellm completes the RB that each cell can send, that is, the data content sent by the UE in the cell within this TTI.
Scheduling/Priority Handling among in Cell根据Scheduling/Priority Handling among Cells for UE调度的结果完成UE在小区内的调度,从而完成UE在小区内载波的选择,实现UE从小区到小区内载波的映射。The Scheduling/Priority Handling among in Cell completes the scheduling of the UE in the cell according to the scheduling result of the Scheduling/Priority Handling among Cells for UE, thereby completing the selection of the UE in the cell, and realizing the mapping of the UE from the cell to the carrier in the cell.
Multiplexing UE in CC完成每个载波最终可以发送的数据,即在此TTI内,该UE在该cell内发送的数据内容,完成UE从cell-cell内载波承载传输信道的映射。The multiplexed UE in CC completes the data that can be sent by each carrier, that is, the data content sent by the UE in the cell in the TTI, and completes the mapping of the UE from the carrier-bearing transport channel in the cell-cell.
Unicast Scheduling/Priority Handling和Multiplexing UE完成本UE在该载波内的调度,功能与传统的MAC功能相同,完成UE的cell内载波承载的传输信道-cell内载波承载的物理信道的映射。The Unicast Scheduling/Priority Handling and the Multiplexing UE complete the scheduling of the UE in the carrier, and the function is the same as the traditional MAC function, and completes the mapping of the physical channel carried by the carrier in the carrier channel of the UE in the cell.
上行CCCH功能:UE可以根据其在每个cell上的信道质量(来自于物理层的测量),选择最合适的空口信道发送给网络侧,即随机接入过程中,UE可以在不同的cell上分别发送Msg1/Msg3,所以CCCH需要经过cell和UE两级调度。Uplink CCCH function: The UE can select the most suitable air interface channel to send to the network side according to the channel quality (measurement from the physical layer) on each cell. That is, the UE can be on different cells during the random access process. The Msg1/Msg3 is sent separately, so the CCCH needs to be scheduled by the cell and the UE.
调度时,快速控制MAC首先进行cell级调度,根据cell的质量信息(包括负载、边缘的PRB数目等)和每个UE在其相关cell上的空口质量,快速控制MAC完成一个UE和若干个cells的映射处理,决策每个UE可以在若干个cell上收发数据,根据UE的需求为其配置若干个最合适的cells完成数据在空口的传输。其次,实时MAC根据UE的具体需求完成UE和cell级的无线资源的映射功能,并完成UE发送的packet大小计算。最后,如果是下行处理,根据packet大小向RLC申请数据;如果是上行数据,则等待UE发送。 During scheduling, the fast control MAC first performs cell-level scheduling, and according to the quality information of the cell (including the load, the number of PRBs of the edge, etc.) and the quality of the air interface of each UE on its associated cell, the MAC is quickly controlled to complete one UE and several cells. The mapping process determines that each UE can send and receive data on several cells, and configures a plurality of most suitable cells according to the requirements of the UE to complete data transmission in the air interface. Secondly, the real-time MAC completes the mapping function of the radio resources of the UE and the cell according to the specific requirements of the UE, and completes the calculation of the packet size sent by the UE. Finally, if it is downlink processing, the data is requested from the RLC according to the packet size; if it is the uplink data, it is waiting for the UE to send.
可见,通过采用上述方案,就能够将MAC协议实体划分为两类,分别为快速控制MAC实体以及至少一个实时MAC实体,将快速控制MAC实体设置在RCC中,实时MAC实体设置在RRS中,并且由快速控制MAC实体针对至少一个实时MAC实体进行控制信令的发送。从而保证了,即便在5G中的cell数目增加很多的场景之下,云中心处可以通过增加快速控制MAC实体保证了其计算能力,并且通过一个快速控制MAC实体控制多个实时MAC实体保证了有效支撑大规模的MAC,提升了系统的处理效率。It can be seen that, by adopting the foregoing solution, the MAC protocol entity can be divided into two types, namely, a fast control MAC entity and at least one real-time MAC entity, and the fast control MAC entity is set in the RCC, and the real-time MAC entity is set in the RRS, and The transmission of control signaling is performed by the fast control MAC entity for at least one real-time MAC entity. Therefore, it is ensured that even in the scenario where the number of cells in the 5G increases a lot, the cloud center can ensure its computing capability by adding a fast control MAC entity, and the control of multiple real-time MAC entities through a fast control MAC entity ensures effective Supporting large-scale MAC, improving the processing efficiency of the system.

本申请,针对5G接入网络的分布式架构和空口特性需求,以及目前MAC协议实体功能的局限性问题,提出了一种具有空口快速信令能力的总分式MAC方案,该方案在兼容已有MAC协议栈功能的基础增加了新的处理功能。In this application, for the distributed architecture and air interface feature requirements of the 5G access network, and the limitations of the current MAC protocol entity function, a total fractional MAC scheme with air interface fast signaling capability is proposed, and the scheme is compatible. The basis for the MAC protocol stack function adds new processing capabilities.
FC-MAC功能为新增MAC功能,所述快速信令(RC)-MAC实体与RT-MAC实体之间的关系为:全部MAC实体由FC MAC实体以及RT MAC实体共同组成;并且FC MAC实体以及RT MAC实体之间不具备交集。FC-MAC不改变RT-MAC的基本功能,以保证总分式的MAC方案对原有MAC的完全兼容性。The FC-MAC function is a new MAC function, and the relationship between the fast signaling (RC)-MAC entity and the RT-MAC entity is: all MAC entities are jointly composed of an FC MAC entity and an RT MAC entity; and the FC MAC entity And there is no intersection between RT MAC entities. The FC-MAC does not change the basic functions of the RT-MAC to ensure full compatibility of the MAC scheme of the total fraction with the original MAC.
下面结合图4a、图5a、图5b和图5c,具体说明FC MAC实体的多种功能及其实现: The various functions of the FC MAC entity and their implementation are specifically described below with reference to FIG. 4a, FIG. 5a, FIG. 5b and FIG. 5c:
第一种、The first,
如图7b所示,所述快速控制MAC实体,还包括:As shown in FIG. 7b, the fast control MAC entity further includes:
信息获取单元73,用于从无线资源控制RRC实体获取到RRC信令的内容;An information acquiring unit 73, configured to acquire, by the radio resource control RRC entity, content of the RRC signaling;

其中,所述指令生成单元71,用于所述快速控制MAC实体通过预设的特殊的PDCCH或者定义的MAC控制元素(CE,Control Element)进行调度指令的封装。The instruction generating unit 71 is configured to encapsulate, by the fast control MAC entity, a scheduling instruction by using a preset special PDCCH or a defined MAC control element (CE, Control Element).
具体来说,比如,参见图4a,所述快速控制MAC实体承接RRC协议信令功能,包括:原有RRC协议实体的信令功能需要实现快速控制而下沉到MAC的功能。Specifically, for example, referring to FIG. 4a, the fast control MAC entity performs the RRC protocol signaling function, including: the signaling function of the original RRC protocol entity needs to implement fast control and sink to the MAC.
其中,所述RRC信令包括:空口切换信令和/或无线链路重配置信令。The RRC signaling includes: air interface switching signaling and/or radio link reconfiguration signaling.
也就是说,通过将空口切换的相关信令下沉到快速控制MAC实体来实现,原有通过RRC空口信令进行控制,现在可以通过FC-MAC发送特殊的PDCCH或者定义的MAC CE进行快速控制。That is to say, by sinking the relevant signaling of the air interface handover to the fast control MAC entity, the original control by RRC air interface signaling can now be performed by the FC-MAC to send a special PDCCH or a defined MAC CE for fast control. .
再比如为了实现空口的无缝(Seamless)切换,通过FC-MAC发送链路控制信令取代原有RRC协议实体的无线链路重配置信令。For example, in order to implement seamless switching of the air interface, the FC-MAC sends link control signaling to replace the radio link reconfiguration signaling of the original RRC protocol entity.
第二种、Second,
信息获取单元,用于获取到所述至少一个实时MAC实体的处理负荷以及空间覆盖情况、以及终端设备的特征参数;An information acquiring unit, configured to acquire a processing load and a spatial coverage of the at least one real-time MAC entity, and a feature parameter of the terminal device;

其中,所述实时MAC实体在本功能中用于承载的小区级和用户级信令/数据的实时映射调度控制。The real-time MAC entity is used in this function for real-time mapping scheduling control of cell-level and user-level signaling/data carried.
具体的,信息获取单元,用于获取到自身管理的至少一个实时MAC实体中的处理负荷、对应的空间覆盖,以及获取到至少一个终端设备上报的空口质量、邻区空口质量、移动方向等等各种空口特征参数、小区特征参数和用户特征参数。Specifically, the information acquiring unit is configured to obtain a processing load, a corresponding spatial coverage, and an air interface quality, a neighboring air interface quality, a moving direction, and the like, which are reported by the at least one real-time MAC entity that is managed by the terminal device. Various air interface characteristic parameters, cell characteristic parameters and user characteristic parameters.
所述指令生成单元,用于为上述至少一个终端设备中的每一个终端设备均分配对应的目标实时MAC实体,将分配的目标实时MAC实体作为上述每一个终端设备对应的第一分配结果。The command generating unit is configured to allocate a corresponding target real-time MAC entity to each of the at least one terminal device, and use the allocated target real-time MAC entity as the first allocation result corresponding to each of the terminal devices.
可以理解的是,本功能中,至少一个终端设备可以为多个;进一步地,其中,每一个终端设备可以均为已经选定其所要接入的目标小区的终端设备;也就是说,本功能中主要针对了对小区内的至少一个终端设备选取对应的目标实时MAC实体。It can be understood that, in this function, at least one terminal device may be multiple; further, each terminal device may be a terminal device that has selected a target cell to which it is to be accessed; that is, this function The method is mainly for selecting a corresponding target real-time MAC entity for at least one terminal device in the cell.
具体的,为所述终端设备选取目标实时MAC实体的方式可以为结合每一个实时MAC实体所服务的小区、支持的终端设备的业务类型、以及其当前负荷,再结合所述终端设备的空口质量、邻区空口质量、移动方向,为每个用户选择出合适的RT-MAC进行数据收发。Specifically, the manner in which the target real-time MAC entity is selected for the terminal device may be a combination of a cell served by each real-time MAC entity, a service type of the supported terminal device, and a current load thereof, and combined with the air interface quality of the terminal device. The quality of the air interface in the neighboring area and the direction of movement, and select the appropriate RT-MAC for each user to send and receive data.
另外,在本功能的实现中,还可以包括有确定每一个实时MAC实体的承载的终端设备的数量以及承载的业务类型,具体如下:In addition, in the implementation of the function, the number of the terminal devices that determine the bearer of each real-time MAC entity and the type of the carried service may also be included, as follows:
所述指令生成单元,用于获取到所述至少一个实时MAC实体的处理负荷以及空间覆盖情况、以及终端设备的特征参数;The instruction generating unit is configured to acquire a processing load and a spatial coverage condition of the at least one real-time MAC entity, and a feature parameter of the terminal device;
基于所述至少一个实时MAC实体的处理负荷以及空间覆盖情况以及终端设备的特征参数,为所述至少一个实时MAC实体中的每一个实时MAC实体确定其承载的终端设备的数量和/或支持的业务类型;Determining, for each of the at least one real-time MAC entity, the number of terminal devices and/or supported by the real-time MAC entity of the at least one real-time MAC entity based on a processing load of the at least one real-time MAC entity and a spatial coverage condition and a characteristic parameter of the terminal device business type;
将所述至少一个实时MAC实体承载的终端设备的数量和/或支持的业 务类型作为调度指令。The number of terminal devices and/or supported industries carried by the at least one real-time MAC entity The transaction type is used as a scheduling instruction.
也就是说,如果当前某一个RT-MAC实体的负载较大,那么就确定其能够承载的用户数量较少,反之可以较大。进一步地,如果某一个RT-MAC实体的负载较大,那么可以为其分配用于承载负荷需求较小的业务类型。从而实现为每个RT-MAC选择合理的承载的用户数量或者用户业务类型(能够确保业务的QoS要求)。That is to say, if the current RT-MAC entity has a large load, it is determined that the number of users that it can carry is small, and vice versa. Further, if the load of an RT-MAC entity is large, it can be allocated a service type for carrying a small load demand. Therefore, it is possible to select a reasonable number of users or user service types for each RT-MAC (to ensure the QoS requirements of the service).
上述第二种功能中快速控制MAC实体与实时MAC实体之间的连接关系可以参见图4a。通过上述功能能够实现由快速控制MAC进行用户也就是终端设备和实时MAC实体之间的双向动态实时映射的控制。For the connection between the MAC entity and the real-time MAC entity, the connection between the MAC function and the real-time MAC entity can be seen in Figure 4a. Through the above functions, the control of the bidirectional dynamic real-time mapping between the user, that is, the terminal device and the real-time MAC entity, by the fast control MAC can be realized.

具体的,比如,参见图4a,RT-MAC实时功能的动态调度控制。根据RRC信令的总体性控制(RRC通过信令配置功能可选集合,MAC在该功能集合中给RT-MAC选择具体的功能),对RT-MAC功能进行调度控制,包括是否只进行控制面(Control Plane)或者用户面(User Plane)相应数据的收发,还是同时可以进行Control Plane和User Plane数据的收发。Specifically, for example, see FIG. 4a, dynamic scheduling control of the RT-MAC real-time function. According to the overall control of the RRC signaling (the RRC is configured by the signaling configuration function, the MAC selects a specific function for the RT-MAC in the function set), and performs scheduling control on the RT-MAC function, including whether only the control plane is performed. (Control Plane) or user plane (User Plane) corresponding data transmission and reception, or control Plane and User Plane data can be sent and received at the same time.
第四种、Fourth,
所述指令生成单元,用于为所述终端设备选取空口承载方式;基于为所述终端设备选取的空口承载方式,生成针对所述终端设备的目标实时MAC实体的调度指令。The command generating unit is configured to select an air interface bearer mode for the terminal device, and generate a scheduling instruction for the target real-time MAC entity of the terminal device based on the air interface bearer mode selected by the terminal device.
具体的,所述快速控制MAC实体为所述终端设备选取空口承载方式, 的确定方式可以为:通过RT-MAC和物理层(PHY)上报的各个终端设备的各种测量信息,通过所述各个终端设备的测量信息准确感知到各个终端设备在空口的传输资源需求;获取到RRC实体的信令的内容;结合所述各个终端设备在空口的传输资源需求以及RRC实体的信令的内容,为每一个终端设备选择空口承载方式。Specifically, the fast control MAC entity selects an air interface bearer mode for the terminal device, The determining manner may be: the various measurement information of each terminal device reported by the RT-MAC and the physical layer (PHY), and the transmission resource requirements of each terminal device in the air interface are accurately perceived by the measurement information of the respective terminal devices; The content of the signaling to the RRC entity; the air interface bearer mode is selected for each terminal device in combination with the transmission resource requirements of the respective terminal devices in the air interface and the signaling content of the RRC entity.
其中,获取RRC实体的信令的内容,可以为RRC实体仍然执行为终端设备进行空口承载方式的分配,但是不生成具体的信令,而将空口承载方式发送给快速控制MAC实体,最终使得快速控制MAC实体基于其分配的空口承载方式生成调度指令。其具体的实现流程可以参见图5a,这里不再进行赘述。The content of the signaling of the RRC entity is obtained, and the RRC entity still performs the allocation of the air interface bearer mode for the terminal device, but does not generate the specific signaling, but sends the air interface bearer mode to the fast control MAC entity, which finally makes the fast The control MAC entity generates a scheduling instruction based on its assigned air interface bearer mode. The specific implementation process can be seen in Figure 5a, and details are not described herein.
其中,选取的空口承载方式可以使用OFDM+CDMA的方式承载用户的数据和信令,或者使用非正交的物理层技术启动某些用户的快速数据收发。本实施例中不对终端设备的空口承载方式进行穷举。The selected air interface bearer mode may use the OFDM+CDMA mode to carry user data and signaling, or use non-orthogonal physical layer technology to enable fast data transmission and reception of some users. In this embodiment, the air interface carrying mode of the terminal device is not exhaustive.
第五种、Fifth,
所述指令生成单元,用于确定终端设备所要接入的目标小区;基于所述终端设备所接入的目标小区,根据所述目标小区对应的至少一个实时MAC实体,获取到为所述终端设备分配目标实时MAC实体的第二分配结果;至少基于所述第二分配结果生成针对所述目标实时MAC实体的调度指令。The instruction generating unit is configured to determine a target cell that the terminal device is to access, and obtain, according to the target cell that the terminal device accesses, the at least one real-time MAC entity corresponding to the target cell, to obtain the terminal device.

下行CCCH功能:可以根据每个UE在每个cell上的信道质量,选择每个UE最合适的空口信道,所以CCCH需要经过cell和UE两级调度。The downlink CCCH function: The most suitable air interface channel for each UE can be selected according to the channel quality of each UE on each cell, so the CCCH needs to be scheduled by the cell and the UE.
PCH功能:可以根据每个UE在每个cell上的信道质量,选择每个UE最合适的空口信道,并组合成合适的PCH在空口发送。所以PCH需要经过cell和UE两级调度。PCH function: According to the channel quality of each UE on each cell, the most suitable air interface channel of each UE can be selected and combined into an appropriate PCH to be sent in the air interface. Therefore, the PCH needs to be scheduled by the cell and the UE.
所述信令生成单元,用于为所述终端设备选取空口承载方式;基于为所述终端设备选取的空口承载方式,生成针对所述中的终端设备的目标实时MAC实体的控制指令。The signaling generating unit is configured to select an air interface bearer mode for the terminal device, and generate a control instruction for the target real-time MAC entity of the terminal device in the air port bearer mode selected by the terminal device.

其中,获取RRC实体的信令的内容,可以为RRC实体仍然执行为终端设备进行空口承载方式的分配,但是不再生成具体的信令,而将空口承载方式发送给快速控制MAC实体,最终使得快速控制MAC实体基于器分配的空口承载方式生成调度指令。其具体的实现流程可以参见图5a,这里不再进行赘述。 The content of the signaling of the RRC entity is obtained, and the RRC entity can still perform the allocation of the air interface bearer mode for the terminal device, but the specific signaling is not generated, but the air interface bearer mode is sent to the fast control MAC entity, and finally The fast control MAC entity generates a scheduling instruction based on the air interface bearer mode allocated by the device. The specific implementation process can be seen in Figure 5a, and details are not described herein.
其中,选取的空口承载方式可以使用OFDM+CDMA的方式承载用户的数据和信令,或者使用非正交的物理层技术启动某些用户的快速数据收发。本实施例中不对终端设备的空口承载方式进行穷举。The selected air interface bearer mode may use the OFDM+CDMA mode to carry user data and signaling, or use non-orthogonal physical layer technology to enable fast data transmission and reception of some users. In this embodiment, the air interface carrying mode of the terminal device is not exhaustive.

传统的MAC可以参见图6c,5G的上行MAC增加了针对UE的MAC PDU controller功能和针对UE和cell级和载波级radio resource映射的scheduling/priority handling among cells for UE和Multiplexing UE in cell、scheduling/priority handling in cell和Multiplexing UE in CC功能。The traditional MAC can be seen in Figure 6c. The uplink MAC of 5G adds the MAC PDU controller function for the UE and the scheduling/priority handling among UEs and the Multiplexing UE in cell, scheduling/ for the UE and cell level and carrier level radio resource mapping. Priority handling in cell and Multiplexing UE in CC function.
本实施例的上行总分式MAC的结构以及功能,参见图6d,对于上行MAC而言,FC-MAC的功能能够提供的功能与下行相互对应,也就是说,同样包括Scheduling/Priority Handling among Cells for UE、Multiplexing UEs in Cell、PDU Controller、Scheduling/Priority Handling in Cell、Multiplexing in CC等功能,这些协议功能包含了RT-MAC的控 制和承担的信令控制功能。RT-MAC包括Scheduling/Priority Handling、Multiplexing和HARQ等功能。需要理解的是,这些上行信令的处理功能,均基于接收到终端设备侧在下行信令的控制基础之上主动上报的上行信令,或者是针对下行信令的反馈信息,而对于这些上行信令的处理与下行信令的生成可以互为可逆过程。For the structure and function of the uplink total fractional MAC in this embodiment, refer to FIG. 6d. For the uplink MAC, the function provided by the FC-MAC function corresponds to the downlink, that is, the Scheduling/Priority Handling among Cells are also included. For UE, Multiplexing UEs in Cell, PDU Controller, Scheduling/Priority Handling in Cell, Multiplex in CC, etc. These protocol functions include RT-MAC control. System and bear the signaling control function. RT-MAC includes functions such as Scheduling/Priority Handling, Multiplexing, and HARQ. It should be understood that the processing functions of the uplink signaling are based on receiving uplink signaling that is actively reported by the terminal device on the basis of the downlink signaling control, or feedback information for downlink signaling, and for these uplinks. The processing of signaling and the generation of downlink signaling may be mutually reversible processes.
UE的上行PDU Controller模块完成UE传输的packets在符合MAC指示的大小(Scheduling/Priority Handling among Cells for UE和Unicast Scheduling/Priority Handling功能模块提供)时,确保不对RLC产生任何影响,包括RLC的SN号不能出现剧烈的跳变、给RLC带来除去传统功能外的新增功能等。上行MAC收到的MAC PDU经过MAC解包功能得到SDU后,通过PDU Controller发送RLC进行后继的处理,PDU Controller根据相应的算法确保多个cell发送的PDU不对RLC产生影响。The packets of the UE's uplink PDU Controller module complete the UE transmission are guaranteed to have no impact on the RLC when the packets indicated by the MAC (Scheduling/Priority Handling among Cells for UE and Unicast Scheduling/Priority Handling function modules are provided), including the SN number of the RLC. There can be no violent jumps, and RLC brings new functions beyond the traditional functions. After the MAC PDU received by the uplink MAC obtains the SDU through the MAC unpacking function, the PDU Controller sends the RLC for subsequent processing. The PDU Controller ensures that the PDUs sent by multiple cells do not affect the RLC according to the corresponding algorithm.
Scheduling/Priority Handling among Cells for UE根据网络侧配置UE的多个cell的可选择通道,完成本次UE使用的cells分配,比如多个cell的每个cell上网络侧都给UE配置了周期的SR,UE可以根据空口信道质量,选择合适的cell发送SR。还比如SPS分配的资源、周期上报的CQI等,从而完成UE的逻辑信道到cell的映射。The Scheduling/Priority Handling among Cells for the UE configures the cells allocated by the UE according to the selected channels of the multiple cells of the UE on the network side. For example, the network side of each cell of the multiple cells configures the periodic SR for the UE. The UE can select an appropriate cell to send the SR according to the quality of the air interface channel. For example, the resource allocated by the SPS, the CQI reported periodically, and the like, thereby completing the mapping of the logical channel to the cell of the UE.
Multiplexing UE in Cellm完成每个cell可以发送的RB,即在此TTI内,该UE在该cell内发送的数据内容。Multiplexing UE in Cellm completes the RB that each cell can send, that is, the data content sent by the UE in the cell within this TTI.
Scheduling/Priority Handling among in Cell根据Scheduling/Priority Handling among Cells for UE调度的结果完成UE在小区内的调度,从而完成UE在小区内载波的选择,实现UE从小区到小区内载波的映射。The Scheduling/Priority Handling among in Cell completes the scheduling of the UE in the cell according to the scheduling result of the Scheduling/Priority Handling among Cells for UE, thereby completing the selection of the UE in the cell, and realizing the mapping of the UE from the cell to the carrier in the cell.
Multiplexing UE in CC完成每个载波最终可以发送的数据,即在此TTI内,该UE在该cell内发送的数据内容,完成UE从cell-cell内载波承载传输信道的映射。 The multiplexed UE in CC completes the data that can be sent by each carrier, that is, the data content sent by the UE in the cell in the TTI, and completes the mapping of the UE from the carrier-bearing transport channel in the cell-cell.
Unicast Scheduling/Priority Handling和Multiplexing UE完成本UE在该载波内的调度,功能与传统的MAC功能相同,完成UE的cell内载波承载的传输信道-cell内载波承载的物理信道的映射。The Unicast Scheduling/Priority Handling and the Multiplexing UE complete the scheduling of the UE in the carrier, and the function is the same as the traditional MAC function, and completes the mapping of the physical channel carried by the carrier in the carrier channel of the UE in the cell.
上行CCCH功能:UE可以根据其在每个cell上的信道质量(来自于物理层的测量),选择最合适的空口信道发送给网络侧,即随机接入过程中,UE可以在不同的cell上分别发送Msg1/Msg3,所以CCCH需要经过cell和UE两级调度。Uplink CCCH function: The UE can select the most suitable air interface channel to send to the network side according to the channel quality (measurement from the physical layer) on each cell. That is, the UE can be on different cells during the random access process. The Msg1/Msg3 is sent separately, so the CCCH needs to be scheduled by the cell and the UE.
调度时,MAC首先进行cell级调度。根据cell的质量信息(包括负载、边缘的PRB数目等)和每个UE在其相关cell上的空口质量,MAC完成一个UE和若干个cells的映射处理,决策每个UE可以在若干个cell上收发数据,根据UE的需求为其配置若干个最合适的cells完成数据在空口的传输。其次,MAC根据UE的具体需求完成UE和cell级的无线资源的映射功能,并完成UE发送的packet大小计算。最后,如果是下行处理,根据packet大小向RLC申请数据;如果是上行数据,则等待UE发送。When scheduling, the MAC first performs cell-level scheduling. According to the quality information of the cell (including the load, the number of PRBs of the edge, etc.) and the quality of the air interface of each UE on its associated cell, the MAC completes mapping processing of one UE and several cells, and determines that each UE can be on several cells. The data is sent and received, and a number of most suitable cells are configured according to the requirements of the UE to complete the transmission of data in the air interface. Secondly, the MAC completes the mapping function of the radio resources of the UE and the cell according to the specific requirements of the UE, and completes the calculation of the packet size sent by the UE. Finally, if it is downlink processing, the data is requested from the RLC according to the packet size; if it is the uplink data, it is waiting for the UE to send.
可见,通过采用上述方案,就能够将MAC协议实体划分为两类,分别为快速控制MAC实体以及至少一个实时MAC实体,将快速控制MAC实体设置在RCC中,实时MAC实体设置在RRS中,并且由快速控制MAC实体针对至少一个实时MAC实体进行控制信令的发送。从而保证了,即便在5G中的cell数目增加很多的场景之下,云基站可以提供更充沛的计算能力,可以有效支撑大规模的MAC。It can be seen that, by adopting the foregoing solution, the MAC protocol entity can be divided into two types, namely, a fast control MAC entity and at least one real-time MAC entity, and the fast control MAC entity is set in the RCC, and the real-time MAC entity is set in the RRS, and The transmission of control signaling is performed by the fast control MAC entity for at least one real-time MAC entity. Therefore, even in the scenario where the number of cells in the 5G increases a lot, the cloud base station can provide more computing power and can effectively support a large-scale MAC.
实施例五、Embodiment 5
本申请提供了一种实体管理系统,如图9所示,所述系统包括:快速控制MAC实体91以及至少一个实时MAC实体92;其中,The present application provides an entity management system. As shown in FIG. 9, the system includes: a fast control MAC entity 91 and at least one real-time MAC entity 92;

实时MAC实体92,用于接收到所述快速控制MAC实体发来的调度指令,以及根据所述调度指令进行处理。The real-time MAC entity 92 is configured to receive a scheduling instruction sent by the fast control MAC entity, and perform processing according to the scheduling instruction.
本申请针对5G接入网络的分布式架构和空口特性需求,以及目前MAC协议实体功能的局限性问题,提出了一种具有空口快速信令能力的总分式MAC方案,该方案在兼容已有MAC协议栈功能的基础增加了新的处理功能。This application proposes a total fractional MAC scheme with air interface fast signaling capability for the distributed architecture and air interface feature requirements of the 5G access network and the limitations of the current MAC protocol entity function. The basis of the MAC protocol stack functionality adds new processing capabilities.
MAC协议实体功能总方案如图3所示。本实施例中将MAC协议实体功能划分为两个功能模块:快速控制(FC)-MAC实体和实时(RT)-MAC实体。其中,FC-MAC分为快速控制功能(Fast Signaling Control)和RT-MAC调度控制功能(RT-MAC Control)两个功能。RT-MAC即为目前现有或者目前传统MAC协议实体功能。The overall scheme of the MAC protocol entity function is shown in Figure 3. In this embodiment, the MAC protocol entity function is divided into two functional modules: a fast control (FC)-MAC entity and a real-time (RT)-MAC entity. Among them, FC-MAC is divided into two functions: Fast Signaling Control (RT) and RT-MAC Control (RT-MAC Control). RT-MAC is the current or current traditional MAC protocol entity function.
为了保证协议栈的兼容性,把传统的MAC功能统一定义成RT-MAC,完成面向小区内用户调度、小区内无线资源分配、小区内用户和无线资源相应过程的控制,RT-MAC功能只聚焦于小区内的相应的MAC功能。In order to ensure the compatibility of the protocol stack, the traditional MAC function is uniformly defined as RT-MAC, and the control for the intra-cell user scheduling, the intra-cell radio resource allocation, the intra-cell user and the radio resource corresponding process is completed, and the RT-MAC function only focuses. The corresponding MAC function within the cell.
具体来说,如图3所示,FC-MAC主要包括两个大功能:承担的快速控制功能,即传统上是通过RRC信令进行交互的控制过程,下沉到MAC通过空口调度进行快速控制功能;对RT-MAC的调度控制过程(不包括信令控制功能),该功能重点完成对RT-MAC的调度以及为了完成调度而需要的非信令式的控制功能。Specifically, as shown in FIG. 3, the FC-MAC mainly includes two major functions: a fast control function that is assumed, that is, a control process that is traditionally performed through RRC signaling, and sinks to the MAC to perform fast control through air interface scheduling. Function; scheduling control process for RT-MAC (excluding signaling control function), this function focuses on the scheduling of RT-MAC and the non-signaling control functions required to complete the scheduling.
下面具体说明本系统能够执行的各种功能及其具体实现:The following describes the various functions that the system can perform and its specific implementation:
第一种、The first,
如图10所示,所述系统还包括:As shown in FIG. 10, the system further includes:
RRC实体93,用于为快速控制MAC实体提供RRC信令的内容; An RRC entity 93, configured to provide RRC signaling content for the fast control MAC entity;
相应的,所述快速控制MAC实体91,用于基于所述RRC信令的内容,生成针对所述至少一个实时MAC实体92的调度指令。Correspondingly, the fast control MAC entity 91 is configured to generate a scheduling instruction for the at least one real-time MAC entity 92 based on the content of the RRC signaling.
其中,所述快速控制MAC实体通过预设的特殊的PDCCH或者定义的MAC控制元素(CE,Control Element)进行调度指令的封装。The fast control MAC entity encapsulates the scheduling instruction by using a preset special PDCCH or a defined MAC control element (CE, Control Element).
具体来说,比如,参见图4a,所述快速控制MAC实体承接RRC协议信令功能,包括:原有RRC协议实体的信令功能需要实现快速控制而下沉到MAC的功能。Specifically, for example, referring to FIG. 4a, the fast control MAC entity performs the RRC protocol signaling function, including: the signaling function of the original RRC protocol entity needs to implement fast control and sink to the MAC.
其中,所述RRC信令包括:空口切换信令和/或无线链路重配置信令。The RRC signaling includes: air interface switching signaling and/or radio link reconfiguration signaling.
也就是说,通过将空口切换的相关信令下沉到快速控制MAC实体来实现,原有通过RRC空口信令进行控制,现在可以通过FC-MAC发送特殊的PDCCH或者定义的MAC CE进行快速控制。That is to say, by sinking the relevant signaling of the air interface handover to the fast control MAC entity, the original control by RRC air interface signaling can now be performed by the FC-MAC to send a special PDCCH or a defined MAC CE for fast control. .
再比如为了实现空口的无缝(Seamless)切换,通过FC-MAC发送链路控制信令取代原有RRC协议实体的无线链路重配置信令。For example, in order to implement seamless switching of the air interface, the FC-MAC sends link control signaling to replace the radio link reconfiguration signaling of the original RRC protocol entity.
第二种、Second,
所述快速控制媒介访问控制MAC实体获取到所述至少一个实时MAC实体的处理负荷以及空间覆盖情况、以及终端设备的特征参数;基于所述至少一个实时MAC实体的处理负荷以及空间覆盖情况以及终端设备的特征参数,为所述终端设备分配目标实时MAC实体作为第一分配结果;至少基于所述第一分配结果生成针对所述目标实时MAC实体的调度指令。The fast control medium access control MAC entity acquires processing load and spatial coverage of the at least one real-time MAC entity, and characteristic parameters of the terminal device; based on processing load and spatial coverage of the at least one real-time MAC entity, and the terminal a feature parameter of the device, the target real-time MAC entity is allocated to the terminal device as a first allocation result; and a scheduling instruction for the target real-time MAC entity is generated based on at least the first allocation result.
其中,所述实时MAC实体在本功能中用于承载的小区级和用户级信令/数据的实时映射调度控制。The real-time MAC entity is used in this function for real-time mapping scheduling control of cell-level and user-level signaling/data carried.
具体的,获取到所述至少一个实时MAC实体的处理负荷以及空间覆盖情况、以及终端设备的特征参数,可以包括:Specifically, the processing load and the spatial coverage of the at least one real-time MAC entity and the characteristic parameters of the terminal device may be:
获取到自身管理的至少一个实时MAC实体中的处理负荷、对应的空间覆盖,以及获取到至少一个终端设备上报的空口质量、邻区空口质 量、移动方向等等各种空口特征参数、小区特征参数和用户特征参数。Obtaining processing load, corresponding spatial coverage, and obtaining air interface quality and neighboring air quality of at least one real-time MAC entity managed by the terminal device Various air interface characteristic parameters, cell characteristic parameters and user characteristic parameters, such as quantity, moving direction, and the like.
为所述终端设备分配目标实时MAC实体作为第一分配结果可以为:为上述至少一个终端设备中的每一个终端设备均分配对应的目标实时MAC实体,将分配的目标实时MAC实体作为上述每一个终端设备对应的第一分配结果。Assigning the target real-time MAC entity to the terminal device as the first allocation result may be: assigning a corresponding target real-time MAC entity to each of the at least one terminal device, and using the allocated target real-time MAC entity as each of the foregoing The first allocation result corresponding to the terminal device.
可以理解的是,本功能中至少一个终端设备可以为多个;进一步地,其中,每一个终端设备可以均为已经选定其所要接入的目标小区的终端设备;也就是说,本功能中主要针对了对小区内的至少一个终端设备选取对应的目标实时MAC实体。It can be understood that at least one terminal device in the function may be multiple; further, each terminal device may be a terminal device that has selected a target cell to which it is to be accessed; that is, in this function The method is mainly for selecting a corresponding target real-time MAC entity for at least one terminal device in the cell.
具体的,为所述终端设备选取目标实时MAC实体的方式可以为结合每一个实时MAC实体所服务的小区、支持的终端设备的业务类型、以及其当前负荷,再结合所述终端设备的空口质量、邻区空口质量、移动方向,为每个用户选择出合适的RT-MAC进行数据收发。Specifically, the manner in which the target real-time MAC entity is selected for the terminal device may be a combination of a cell served by each real-time MAC entity, a service type of the supported terminal device, and a current load thereof, and combined with the air interface quality of the terminal device. The quality of the air interface in the neighboring area and the direction of movement, and select the appropriate RT-MAC for each user to send and receive data.
另外,在本功能的实现中,还可以包括有确定每一个实时MAC实体的承载的终端设备的数量以及承载的业务类型,具体如下,所述快速控制媒介访问控制MAC实体确定针对所述至少一个实时MAC实体的调度指令,至少还包括:In addition, in the implementation of the function, the number of the terminal devices that determine the bearer of each real-time MAC entity and the type of the bearer service may be further included. Specifically, the fast control medium access control MAC entity determines that the at least one The scheduling instruction of the real-time MAC entity includes at least:
获取到所述至少一个实时MAC实体的处理负荷以及空间覆盖情况、以及终端设备的特征参数;Obtaining a processing load and a spatial coverage condition of the at least one real-time MAC entity, and a feature parameter of the terminal device;
基于所述至少一个实时MAC实体的处理负荷以及空间覆盖情况以及终端设备的特征参数,为所述至少一个实时MAC实体中的每一个实时MAC实体确定其承载的终端设备的数量和/或支持的业务类型;Determining, for each of the at least one real-time MAC entity, the number of terminal devices and/or supported by the real-time MAC entity of the at least one real-time MAC entity based on a processing load of the at least one real-time MAC entity and a spatial coverage condition and a characteristic parameter of the terminal device business type;
将所述至少一个实时MAC实体承载的终端设备的数量和/或支持的业务类型作为调度指令。The number of terminal devices carried by the at least one real-time MAC entity and/or the type of service supported are used as scheduling instructions.
也就是说,如果当前某一个RT-MAC实体的负载较大,那么就确定 其能够承载的用户数量较少,反之可以较大。进一步地,如果某一个RT-MAC实体的负载较大,那么可以为其分配用于承载负荷需求较小的业务类型。从而实现为每个RT-MAC选择合理的承载的用户数量或者用户业务类型(能够确保业务的QoS要求)。In other words, if the current RT-MAC entity has a large load, then it is determined It can carry fewer users, and vice versa. Further, if the load of an RT-MAC entity is large, it can be allocated a service type for carrying a small load demand. Therefore, it is possible to select a reasonable number of users or user service types for each RT-MAC (to ensure the QoS requirements of the service).
上述第二种功能中快速控制MAC实体与实时MAC实体之间的连接关系可以参见图4a。通过上述功能能够实现由快速控制MAC进行用户也就是终端设备和实时MAC实体之间的双向动态实时映射的控制。For the connection between the MAC entity and the real-time MAC entity, the connection between the MAC function and the real-time MAC entity can be seen in Figure 4a. Through the above functions, the control of the bidirectional dynamic real-time mapping between the user, that is, the terminal device and the real-time MAC entity, by the fast control MAC can be realized.
第三种、Third,
快速控制MAC实体91,用于为所述至少一个实时MAC实体中每一个实时MAC实体确定数据传输类型;其中,所述数据传输类型包括控制面的数据传输、和/或、用户面的数据传输;基于所述至少一个实时MAC实体对应的数据传输类型,生成所述调度指令。a fast control MAC entity 91, configured to determine a data transmission type for each real-time MAC entity of the at least one real-time MAC entity; wherein the data transmission type includes data transmission of a control plane, and/or data transmission of a user plane And generating the scheduling instruction based on a data transmission type corresponding to the at least one real-time MAC entity.
具体的,比如,参见图4a,RT-MAC实时功能的动态调度控制。根据RRC信令的总体性控制(RRC通过信令配置功能可选集合,MAC在该功能集合中给RT-MAC选择具体的功能),对RT-MAC功能进行调度控制,包括是否只进行控制面(Control Plane)或者用户面(User Plane)相应数据的收发,还是同时可以进行Control Plane和User Plane数据的收发。Specifically, for example, see FIG. 4a, dynamic scheduling control of the RT-MAC real-time function.

Therefore, the cell has two core features: 1. physical resources; 2. management and control for these physical resources. At the same time, the cell also needs corresponding cell-level signaling to complete the control of the air interface, such as cell broadcast, cell establishment, deletion, reconfiguration, blocking, and the like. Based on defining the PHY and the MAC within the cell, the cell is defined as:
PHY层功能实体即为小区内物理资源,一个PHY层功能实体唯一地确定一个小区,一个小区只有一个PHY层功能实体,小区内的MAC功能实体完成对PHY的管理和控制,并完成对用户提供统一的无线资源和数据交互接口。PHY层功能实体和小区内的MAC功能共同构成一个小区。在此基础上,还包括小区本身的信令控制功能。The PHY layer function entity is the physical resource in the cell, and one PHY layer function entity uniquely determines one cell. One cell has only one PHY layer function entity, and the MAC function entity in the cell completes management and control of the PHY, and completes providing the user with the PHY layer. Unified wireless resource and data interaction interface. The PHY layer functional entity and the MAC function in the cell together form a cell. On this basis, the signaling control function of the cell itself is also included.
小区的PHY层功能实体是空口无线资源的集合。所有形式的空口都全部体现到本小区的PHY内。空口可能采用了各种形态的天线从而带来空口形态的多样性,比如空口可以是全向天天线的一个360度覆盖区域,也可以是8天线的120度覆盖区域,也可以是大规模天线阵的一个子天线阵(比 如128天线的大规模天线的一个16天线的子天线阵)的较大覆盖范围,也可以是大规模天线中的一个子天线阵的窄覆盖范围(比如很小的一个无线beam)等等,无论是一种空口形态,还是若干种空口形态的组合,都是针对一个PHY所表征的无线资源的空域部分。The PHY layer functional entity of the cell is a collection of air interface radio resources. All forms of air interfaces are embodied in the PHY of the community. The air interface may adopt various forms of antennas to bring about the diversity of air interface patterns. For example, the air interface may be a 360-degree coverage area of the omnidirectional antenna, or a 120-degree coverage area of the 8 antennas, or a large-scale antenna. a sub-antenna array of arrays A larger coverage of a 16-antenna sub-array of a large-scale antenna of 128 antennas may also be a narrow coverage of a sub-antenna array in a large-scale antenna (such as a small wireless beam), etc. Whether it is an air interface form or a combination of several air interface forms, it is a spatial domain part of a radio resource characterized by a PHY.
小区内的MAC实现对用户的统一接口服务,包括为用户提供统一无线资源接口支撑,无论PHY的形态如何,MAC只提供给用户其可以发送的数据量,具体的无线资源形式用户不可见,用户只需要按照MAC提供的发送数据需求供应数据即可。小区内的MAC和用户之间交互的只有用户需要发送的数据、一次可以发送的数据等业务数据相关的交互。The MAC in the cell implements the unified interface service for the user, including providing the user with a unified radio resource interface support. Regardless of the PHY configuration, the MAC only provides the user with the amount of data that can be sent by the user. The specific radio resource form is invisible to the user. You only need to supply data according to the sending data requirements provided by the MAC. The interaction between the MAC and the user in the cell is only the data related to the service data that the user needs to send, and the data that can be sent at one time.
对于用户,为了服务于用户的业务,需要有相关的用户的信令和对用户的控制,信令包括诸如用户的建立、重配置、建立等,以及用户服务数据的相关控制,比如流控、安全性控制等。For the user, in order to serve the user's service, it is necessary to have relevant user signaling and control of the user, such as establishment, reconfiguration, establishment, etc. of the user, and related control of the user service data, such as flow control, Security control, etc.
通过用户信令及控制和小区信令的完全分离,以及MAC的统一接口定义,实现了用户和小区在控制面的完全解耦。通过对用户安全算法的改进(具体算法改进不在本专利讨论范围内),使用户的安全机制与小区无关,小区对于用户而言,仅仅是完成各种数据收发的空口无线资源承载,实现了用户和小区在数据面的完全解耦;通过控制面和数据面的解耦实现了用户和小区的完全解耦。当用户需要发送数据时,向小区内的MAC发起申请而获得相应的无线资源,小区内的MAC收到用户的申请后,以用户业务质量保证需求为标准选择合适的空口资源,从而实现了以用户为中心的无线小区(无线资源)服务。Through the complete separation of user signaling and control and cell signaling, and the unified interface definition of the MAC, the complete decoupling of the user and the cell on the control plane is realized. Through the improvement of the user security algorithm (the specific algorithm improvement is not within the scope of this patent), the security mechanism of the user is independent of the cell, and the cell is only for the user to complete the air interface radio resource bearer of various data transceiving, realizing the user. Complete decoupling of the cell from the data plane; complete decoupling of the user and the cell by decoupling the control plane and the data plane. When the user needs to send data, the application is initiated to the MAC in the cell to obtain the corresponding radio resource. After receiving the user's application, the MAC in the cell selects an appropriate air interface resource based on the user service quality assurance requirement, thereby realizing User-centric wireless cell (radio resource) service.
用户申请无线资源,除了申请小区内的无线资源外,为了更好地服务于用户的业务需求,还需要根据用户的空口信道质量选择使用哪个小区内的无线资源,即需要选择小区。In order to better serve the service requirements of the user, the user needs to select the radio resource in the cell according to the quality of the air interface channel of the user, that is, the cell needs to be selected.
如图15所示,基于单小区的定义给出了支持多小区协作的小区定义, 存在多个PHY时即存在多个小区。As shown in FIG. 15, a cell definition supporting multi-cell cooperation is given based on the definition of a single cell. There are multiple cells when there are multiple PHYs.
当用户可以在多个PHY上收发数据或者有多个PHY可供选择收发数据时,需要根据用户在每个PHY上的空口信号质量(空口信道质量)动态的选择合适的一个或者多个小区支撑用户的数据收发。同时,因为小区可以动态选择,需要及时通知接收端能够正确接受,所以,基于小区给用户提供统一的无线资源接口的原则,增加了跨小区MAC(Cross-cell MAC)功能。When the user can send and receive data on multiple PHYs or multiple PHYs can choose to send and receive data, it is necessary to dynamically select the appropriate one or more cell supports according to the air interface signal quality (air interface channel quality) of the user on each PHY. User data is sent and received. At the same time, because the cell can be dynamically selected, it needs to notify the receiving end to correctly accept it. Therefore, based on the principle that the cell provides a unified radio resource interface to the user, the cross-cell MAC function is added.
跨小区MAC:以小区为单位管理和控制小区级的无线资源,包括小区间的干扰协调、小区间的防碰撞调度、给用户动态调度可用的小区,并给用户提供小区级的无线资源接口。Cross-cell MAC: manages and controls cell-level radio resources in units of cells, including interference coordination between cells, anti-collision scheduling between cells, dynamically scheduling available cells to users, and providing users with cell-level radio resource interfaces.
跨小区MAC与小区内MAC共同完成给用户提供统一的小区级和小区内无线资源接口;共同完成小区间和小区内无线资源的管理。The cross-cell MAC and the intra-cell MAC jointly provide the user with a unified cell-level and intra-cell radio resource interface; and jointly manage the inter-cell and intra-cell radio resources.
跨小区MAC和小区内MAC可以统一为一个MAC功能实体,即MAC功能实体具有跨小区调度和小区内调度两种功能。The cross-cell MAC and the intra-cell MAC may be unified into one MAC functional entity, that is, the MAC functional entity has two functions of cross-cell scheduling and intra-cell scheduling.
以用户为中心的无线空口小区方案中,增加了小区级的功能后,小区的功能包括小区内的控制/管理功能和跨小区的协作功能,都属于MAC功能。没有改变PHY的无线资源定义和用户指包含业务的定义。In the user-centric wireless air interface cell scheme, after the cell level function is added, the functions of the cell include the control/management function in the cell and the cooperation function of the inter-cell, all of which belong to the MAC function. There is no change to the PHY's radio resource definition and the user refers to the definition of the included service.
如图15所示,本申请实施例的技术方案还支持基于多小区的跨小区调度功能,以用户为中心的小区方案完全实现了以用户为中心的目标:As shown in FIG. 15, the technical solution of the embodiment of the present application further supports a multi-cell based cross-cell scheduling function, and the user-centered cell scheme fully implements a user-centric target:
1、针对用户,通过跨载波MAC快速调度小区,实现了收发数据可以选择一个或者多个信道质量好的小区;而用户移动时,通过快速调度实现小区的快速接力调度,可以做到用户无感知。1. For the user, the cell is quickly scheduled by the cross-carrier MAC, and the receiving and receiving data can be selected to select one or more cells with good channel quality; and when the user moves, the fast relay scheduling of the cell can be realized through fast scheduling, so that the user can be made without perception. .
2、用户与使用的小区之间解耦,没有绑定关系,小区仅仅是用户收发数据的物理资源,通过两级MAC,分别为跨小区MAC(比如可以为快速控制MAC实体的一种具体实施方式)和小区内MAC(可以为前述实施例 的实时MAC实体的一种具体实施方式)的实时调度,调度小区和调度小区内的无线资源都对用户的业务承载(Serve Bearer)不产生任何影响,并且可以实时按照用户在空口的信道质量选择满足用户业务质量要求的无线资源收发数据,实现了小区完全服务于用户。2. Decoupling between the user and the used cell, there is no binding relationship. The cell is only the physical resource for the user to send and receive data. The two-level MAC is the cross-cell MAC (for example, it can be a specific implementation of the MAC entity). Mode) and intra-cell MAC (may be the foregoing embodiment Real-time scheduling of a real-time MAC entity, the radio resources in the scheduling cell and the scheduling cell do not have any impact on the user's service bearer (Serve Bearer), and can be selected in real time according to the channel quality of the user in the air interface. The radio resource that satisfies the user's service quality requirements transmits and receives data, and realizes that the cell completely serves the user.
3、通过PHY管理各种形态的空口,通过MAC快速调度,实现了根据用户的空口质量选择恰当的空口形态承载用户的数据,能够更准确快速的服务于用户。3. Through the PHY to manage various forms of air interface, through MAC fast scheduling, the user can select the appropriate air interface shape to carry the user's data according to the user's air interface quality, and can serve the user more accurately and quickly.
