为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。The technical problems, the technical solutions, and the advantages of the present invention will be more clearly described in conjunction with the accompanying drawings and specific embodiments.
本公开针对相关的MAC功能无法满足5G网络中灵活空口的调度需求的问题，提供一种在MAC层实现空口调度的方法及装置，通过增加MAC对小区和UE在传输时间间隔使用的小区的调度功能，把UE的逻辑信道到小区-小区内的载波-小区内的载波承载的传输信道-小区内的载波承载的物理信道的四映射完全由MAC控制，从而实现灵活空口的需求，满足5G网络的需求。The present disclosure provides a method and apparatus for implementing air interface scheduling in a MAC layer by increasing the MAC address to the scheduling requirement of the flexible air interface in the 5G network, and increasing the scheduling of the cell used by the cell and the UE in the transmission time interval. Function, the logical channel of the UE to the carrier in the cell-cell - the carrier channel in the cell - the four mapping of the physical channel carried by the carrier in the cell is completely controlled by the MAC, thereby realizing the requirement of flexible air interface and satisfying the 5G network Demand.
如图1所示，本公开实施例提供一种在MAC层实现空口调度的方法1，包括：As shown in FIG. 1 , an embodiment of the present disclosure provides a method 1 for implementing air interface scheduling at a MAC layer, including:
步骤11：根据小区的质量信息以及目标UE在对应小区上的空口质量，确定所述目标UE可用的小区集合，将目标UE的逻辑信道映射到所述小区集合上；其中，所述小区集合包括一个以上的小区；Step 11: Determine a set of cells available to the target UE according to the quality information of the cell and the air interface quality of the target UE on the corresponding cell, and map the logical channel of the target UE to the set of cells; wherein the cell set includes More than one cell;
步骤12：根据所述目标UE的数据传输需求，将目标UE映射到该小区集合中的一目标小区内的载波上；Step 12: Map the target UE to a carrier in a target cell in the cell set according to the data transmission requirement of the target UE.
步骤13：根据所述目标UE的数据传输需求，将目标UE映射到所述目标小区内的载波承载的传输信道上；以及Step 13: Map the target UE to a transport channel carried by the carrier in the target cell according to the data transmission requirement of the target UE;
步骤14：根据所述目标UE的数据传输需求，将目标UE映射到所述目 标小区内的载波承载的物理信道上；其中，所述目标小区内的载波承载的物理信道用于承载所述目标UE收发数据的业务。Step 14: Map the target UE to the destination according to the data transmission requirement of the target UE The physical channel carried by the carrier in the target cell is used to carry the service of the target UE to receive and receive data.
本公开的上述实施例为了满足5G的需求，无线资源控制RRC的部分信令控制过程需要下移到媒介访问控制层MAC，通过MAC控制UE的逻辑信道到小区-小区内的载波-小区内的载波承载的传输信道-小区内的载波承载的物理信道的四级映射，以降低信令时延，提高信令的灵活度，适应5G灵活空口的需求。本公开实施例提供的5G的MAC除了传统的UE在小区内的资源调度功能外，还具有UE可用的小区的调度功能以及确定小区内可调度的具体UE的调度功能；即5G的MAC具有小区级和UE级的调度功能。In order to satisfy the requirement of 5G, the foregoing part of the present disclosure needs to move down to the medium access control layer MAC, and control the logical channel of the UE to the carrier-cell in the cell-cell through the MAC. Carrier-transmitted transport channel-four-level mapping of physical channels carried by carriers in a cell to reduce signaling delay, improve signaling flexibility, and adapt to the requirements of 5G flexible air interfaces. The 5G MAC provided by the embodiment of the present disclosure has the scheduling function of the cell available to the UE and the scheduling function of the specific UE that can be scheduled in the cell, in addition to the resource scheduling function of the UE in the cell; that is, the 5G MAC has a cell. Level and UE level scheduling functions.
调度时，MAC首先进行小区级调度。根据小区的质量信息(包括负载、边缘的物理资源块PRB数目等)和每个UE在其相关小区上的空口质量，MAC完成一个UE和若干个小区的映射处理，决策每个UE可以在若干个小区上收发数据，根据UE的需求为其配置若干个最合适的小区完成数据在空口的传输。其次，MAC根据UE的具体需求完成UE和小区级的无线资源的映射功能，并完成UE发送的数据包packet大小计算。最后，如果是下行处理，根据数据包packet大小向无线链路控制层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 physical resource block PRBs of the edge, and the like) 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 each UE may be determined in several The data is transmitted and received on the cells, and a plurality 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 level according to the specific requirements of the UE, and completes the calculation of the packet size of the data packet sent by the UE. Finally, if it is downlink processing, it applies for data to the radio link control layer RLC according to the packet size of the packet; if it is uplink data, it waits for the UE to transmit.
进一步的，由于本公开实施例提供的在MAC层实现空口调度的方法中保留了原MAC的调度功能，则本公开提供的5G的MAC即可满足5G网络需求，也可以兼容4G/3G网络的已有设备，其兼容性好，例如在传统的LTE演进型基站eNB设备中，以基带处理单元BBU为单位支撑上述MAC功能是可行；且5G中的小区数目增加很多，而5G的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，使得5G的MAC具有很好的扩展性。Further, since the scheduling function of the original MAC is retained in the method for implementing the air interface scheduling in the MAC layer provided by the embodiment of the present disclosure, the 5G MAC provided by the present disclosure can meet the requirements of the 5G network, and can also be compatible with the 4G/3G network. The existing device has good compatibility. For example, in the traditional LTE evolved base station eNB device, it is feasible to support the MAC function in units of the baseband processing unit BBU; and the number of cells in the 5G is increased a lot, and the 5G cloud base station can Provide more computing power, can effectively support large-scale MAC, making 5G MAC very scalable.
进一步的，下面将分别从第一数据传输过程(下行过程)和第二数据传输过程(上行过程)对本公开提供的在MAC层实现空口调度的方法进行详细描述。Further, the method for implementing air interface scheduling at the MAC layer provided by the present disclosure will be described in detail from the first data transmission process (downlink process) and the second data transmission process (uplink process), respectively.
具体的，如图2所示为第一数据传输过程中的MAC功能模块示意图，相较于传统的MAC，5G的下行MAC增加了针对UE的协议数据控制模块(PDU controller)、无线资源控制模块(Radio Resource Manager)和信道质 量管理模块(Channel Quality Manager)；针对UE和小区级无线资源映射的针对UE的小区间单播调度/优先级处理模块(unicast scheduling/priority handling among cells for UEs)、决定小区内可调度的UE的小区内复用UE模块(Multiplexing UEs in cell)，以及小区的空口质量管理模块(cells’Radio quality Manager)。通过把传统MAC的单播调度/优先级处理(unicast scheduling/priority handling)和复用(Multiplexing)定义成5G网络中的MAC的UE间的单播调度/优先级处理(unicast scheduling/priority handling among UEs)，其他的保持不变。Specifically, as shown in FIG. 2, it is a schematic diagram of a MAC function module in a first data transmission process. Compared with a conventional MAC, a downlink MAC of 5G adds a protocol data control module (PDU controller) and a radio resource control module for the UE. (Radio Resource Manager) and channel quality QoS management module (Channel Quality Manager); unicast scheduling/priority handling among cells for UEs for UE and cell-level radio resource mapping, determining intra-cell schedulable UEs The multiplexed UEs in cell and the cells' radio quality manager. Unicast scheduling/priority handling among UEs defined by unicast scheduling/priority handling and multiplexing (multiplexed) of MACs in a 5G network (unicast scheduling/priority handling among UEs), the others remain unchanged.
其中，步骤11包括：Wherein step 11 includes:
步骤111：根据目标UE的信道质量、目标UE在对应小区上的空口质量以及无线资源控制RRC配置信息，为所述目标UE分配所述第一数据传输使用的小区集合；并将所述目标UE的逻辑信道映射到所述小区集合上。Step 111: Allocating a cell set used by the first data transmission to the target UE according to a channel quality of the target UE, an air interface quality of the target UE on the corresponding cell, and radio resource control RRC configuration information; and the target UE The logical channel is mapped onto the set of cells.
即如图2所示，针对UE的小区间单播调度/优先级处理模块(Unicast Scheduling/Priority Handling among Cells for UEs)根据UE的信道质量(Channel Quality Manager)、小区的空口质量(Cells’Radio Quality Manager)、业务的特点(无线资源控制RRC的配置)等控制信息完成本次UE使用的若干个小区的分配。本功能模块根据各种空口质量完成每个UE可用的小区的集合，即完成UE的逻辑信道到小区集合的映射。That is, as shown in FIG. 2, the Unicast Scheduling/Priority Handling among Cells (UEs) for the UE is based on the channel quality of the UE (Channel Quality Manager) and the air interface quality of the cell (Cells'Radio). The control information such as the Quality Manager and the characteristics of the service (the configuration of the radio resource control RRC) completes the allocation of several cells used by the UE.

The common control channel (CCCH) function of the downlink control channel: 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. Paging Channel (PCH) function: It can be based on the channel quality of each UE on each cell. Quantity, select the most suitable air interface channel for each UE, and combine them into a suitable PCH to send in the air interface. Therefore, the PCH needs to be scheduled by the cell and the UE.

For example, the network side of each cell of the multiple cells configures a periodic uplink scheduling request SR for the UE, and the UE can select an appropriate cell to send the SR according to the quality of the air interface channel. For example, the resources allocated by the SPS are semi-statically scheduled, the channel quality indicator CQI reported periodically, and the like, thereby completing the logical channel-to-cell mapping of the UE.

On the physical channel.
即如图3所示，UE间的单播调度/优先级处理(Unicast Scheduling/Priority Handling among UEs)和复用UE(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，完成目标UE的目标小区内的载波承载的传输信道-目标小区内的载波承载的物理信道的映射。That is, as shown in FIG. 3, Unicast Scheduling/Priority Handling among UEs and Multiplexed UEs complete the scheduling of the UE in the carrier, and the function and the traditional MAC function. Similarly, the transport channel carried in the target cell of the target UE is completed - the mapping of the physical channel carried by the carrier in the target cell.
需要说明的是，本公开实施例中不仅定义实现上述步骤112、步骤122、步骤132以及步骤142的功能的模块，还定义消除上述模块的影响、管理上述模块的部分信息的模块，具体的，所述第二数据传输过程中所述方法还包括：It should be noted that, in the embodiment of the present disclosure, not only modules that implement the functions of the foregoing steps 112, 122, 132, and 142 are defined, but also modules that eliminate the influence of the foregoing modules and manage part of the information of the modules, specifically, The method in the second data transmission process further includes:
步骤18：将目标UE传输的数据包发送至无线链路控制层RLC，并控制控制多个目标小区发送的数据包与所述无线链路层RLC无关。Step 18: Send the data packet transmitted by the target UE to the radio link control layer RLC, and control to control the data packets sent by the multiple target cells to be independent of the radio link layer RLC.
即如图3所示，该步骤18由UE的无线资源控制模块(Radio Resource Manager)实现，UE的上行协议数据控制模块控制UE传输的数据包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。上行 MAC收到的MAC PDU经过MAC解包功能得到SDU后，通过协议数据控制模块发送RLC进行后继的处理，协议数据控制模块根据相应的算法确保多个小区发送的PDU不对RLC产生影响。That is, as shown in FIG. 3, the step 18 is implemented by the radio resource management module (Radio Resource Manager) of the UE, and the uplink protocol data control module of the UE controls the data packet transmitted by the UE to ensure that the RLC is not generated when the size of the MAC indication is met. Any impact, including the RLC's SN number, cannot be dramatically changed, giving RLC new features beyond the traditional functions. Upstream After the MAC PDU received by the MAC obtains the SDU through the MAC unpacking function, the protocol data control module sends the RLC for subsequent processing. The protocol data control module ensures that the PDUs sent by multiple cells do not affect the RLC according to the corresponding algorithm.
进一步需要说明的是，由于本公开实施例在原有MAC层上增加新的模块以实现新的功能，故其他一些原有模块的功能也需发生相应变化，具体包括：It should be further noted that, as the embodiment of the present disclosure adds a new module to the original MAC layer to implement a new function, the functions of other existing modules also need to be changed accordingly, including:

The UE may separately send the message Msg1/Msg3 in the random access procedure on different cells, so the CCCH needs to be scheduled by the cell and the UE.
另外，图2中DL-SCH为下行共享信道；HARQ为混合自动重传请求；RB为资源块，是LTE中业务资源的调度单位；上述信道均按照原有规则进行数据传输，在此不对其功能进行详细描述。In addition, in FIG. 2, the DL-SCH is a downlink shared channel; the HARQ is a hybrid automatic repeat request; the RB is a resource block, which is a scheduling unit of service resources in the LTE; and the foregoing channels perform data transmission according to the original rules, and are not The function is described in detail.
