Description

用于短周期半静态调度的资源配置方法和装置
本申请要求于2019年1月30日提交中国专利局、申请号为201910093654.6、申请名称为“用于短周期半静态调度的资源配置方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术，尤其涉及一种用于短周期半静态调度的资源配置方法和装置。
背景技术
在长期演进(Long Term Evolution，简称：LTE)系统中，基站(eNodeB，简称：eNB)使用物理下行控制信道(Physical Downlink Control Channel，简称：PDCCH)传输用于调度用户设备(User Equipment，简称：UE)的控制信令。当调度处于连接态的UE时，eNB采用UE的小区无线网络临时标识(Cell Radio Network Temporary Identity，简称：C-RNTI)对控制信令进行加扰，UE在监听到PDCCH上传输的控制信令后，可以用自身的C-RNTI对PDCCH上传输的控制信令进行解扰。控制信令中包括了eNB为UE分配的物理信道资源和具体使用的调制编码方式(Modulation and Coding Scheme，简称：MCS)等，UE按照该控制信令中的指示到对应的物理信道上进行数据的收发。
LTE协议中定义了两种数据调度模式：动态调度和半静态调度(Semi-Persistent Scheduling，简称：SPS)，其中，动态调度方式下，eNB对UE的每个数据包都有一个相应的PDCCH来通知其占用的资源和传输方式。SPS方式下，当UE的SPS被激活后，在后续的数据传输过程中，UE按照无线资源控制(Radio Resource Control，简称：RRC)消息配置的SPS周期在对应的时间点上按照PDCCH控制信令中给UE分配的物理信道资源和MCS发送或接收数据，当需要修改或者释放SPS资源时，eNB可以采用PDCCH控制信令下发SPS修改或者释放命令。第三代合作伙伴计划(3rd Generation Partnership Project，简称：3GPP)协议规定SPS调度周期最短10ms，但这很难满足低时延业务(例如手机游戏、抢红包等)的要求。
目前有一种预调度方案，eNB每隔一个周期主动给UE分配一次物理信道资源和MCS，该周期可以是1～5ms，UE可以根据该物理信道资源和MCS发送缓存状态报告(Buffer Status Report，简称：BSR)，eNB根据可以通过动态调度给UE分配其所需的物理信道资源和MCS。
但是如果在SPS中SPS周期配置的较短，会导致能够做SPS调度的UE数量比较少，且会增加PDCCH开销，同时给邻区带来干扰。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请中将部分带宽或全部带宽用于短周期半静态调度(short-SPS，简称：S-SPS)，并且将用于S-SPS的带宽划分成若干资源块，基站设备通常是将一个S-SPS资源块分配给一个S-SPS UE，至少确保S-SPS UE能够把BSR上报上来。示例性的，图1为本申请可以支持的S-SPS周期示意图，如图1所示，S-SPS周期包括1-5ms，有一个S-SPS资源块，当S-SPS周期为1ms时，相当于是S-SPS UE在每个ms上都会被调度，因此这一个S-SPS资源块只能分配给一个S-SPS UE；当S-SPS周期为2ms时，相当于是同一个S-SPS UE隔1ms被调度一次，因此这一个S-SPS资源块可以轮流被分配给两个S-SPS UE；以此类推，当S-SPS周期为5ms时，这一个S-SPS资源块可以轮流被分配给五个S-SPS UE。
S-SPS UE有三种状态，包括配置、激活和去激活。当S-SPS UE接入时，基站设备可以先给该S-SPS UE进行用于S-SPS的资源配置。当确定有可用的S-SPS资源块时，基站设备激活该S-SPS UE，此时激活的S-SPS UE就可以根据基站设备配置给其的S-SPS周期和S-SPS资源块发送上行数据。当已激活的S-SPS UE的缓存数据量较大时，基站设备对该S-SPS UE去激活，对其进行动态调度，或者当已激活的S-SPS UE的周期需要重新配置时，基站设备也会对该S-SPS UE去激活，然后重新进入配置状态。去激活的S-SPS UE基站设备可以根据其缓存数据量对其重新激活，即当该S-SPS UE的缓存数据量较小时，基站设备可以重新激活。
图2为本申请用于S-SPS的资源配置方法实施例的流程图，如图2所示，本实施例的方法由基站设备执行，该用于短周期半静态调度的资源配置方法可以包括：
步骤101、确定当前已配置为S-SPS的UE，并获取分配给已配置为S-SPS的UE的S-SPS周期和S-SPS资源块。
根据通信网络支持的S-SPS周期等级和配置的S-SPS资源块数量，可以确定该通信网络能够同时最多支持的S-SPS UE数量，例如，S-SPS周期为1ms，S-SPS资源块数量为2，那么最多可支持的S-SPS UE数量为2；S-SPS周期为2ms，S-SPS资源块数量为2，那么最多可支持的S-SPS UE数量为4。因此当有新接入的待配置UE(待配置UE为支持S-SPS的UE)时，基站设备要先确定已配置为S-SPS的UE，并获取分配给这些UE的S-SPS周期和S-SPS资源块。示例性的，图3为本申请S-SPS资源分配的一个示意图，如图3所示，已配置为S-SPS的UE包括UE1、UE2和UE3，其中，UE1的S-SPS周期为1ms，UE2和UE3的S-SPS周期为2ms，UE1独自占用一个S-SPS资源块，UE2和UE3轮流占用另一个S-SPS资源块。
步骤102、根据分配给已配置为S-SPS的UE的S-SPS周期和S-SPS资源块确定待配置UE的S-SPS周期。
基站设备给待配置UE配置S-SPS周期的方法可以包括：
一、当分配给已配置为S-SPS的UE的S-SPS资源块为零时，将待配置UE的S-SPS周期确定为最短周期，最短周期是已设定的递增排列的两个以上周期时长中的最短者。如果当前通信系统中没有被配置为S-SPS的UE，说明还没有S-SPS资源被占用，因此基站设备可以以最短的S-SPS周期(1ms)来配置待配置UE。
二、当分配给已配置为S-SPS的UE的S-SPS周期和S-SPS资源块不为零时，根据分配给已配置为S-SPS的UE的S-SPS周期和S-SPS资源块确定是否存在未分配的S-SPS资源块，若确定存在未分配的S-SPS资源块，则根据未分配的S-SPS资源块对应的周期确定待配置UE的S-SPS周期。示例性的，图4为本申请S-SPS资源分配的另一个示意图，如图4所示，已配置为S-SPS的UE包括UE1和UE2，其中，UE1的S-SPS周期为1ms，UE2的S-SPS周期为2ms，UE1和UE2分别占用一个S-SPS资源块，但是UE1在每1ms上都被分配了一个S-SPS资源块，UE2是隔1ms被分配一个S-SPS资源块，可见UE2没有被调度的1ms上有一个S-SPS资源块未分配，这种情况下，待配置UE(UE3)就可以占用该未分配的S-SPS资源块，其S-SPS周期为2ms，基站设备给UE3分配了S-SPS周期和S-SPS资源块后如图3所示。若未分配的S-SPS资源块有多个，基站设备可以根据UE3的缓存数据量从多个未分配的S-SPS资源块中选择一个或多个分配给UE3。
三、若确定不存在未分配的S-SPS资源块，则确定已配置为S-SPS的UE的数量是否小于可配置总量，可配置总量为分配给已配置为S-SPS的UE的S-SPS周期中最长者对应的可进行S-SPS的UE总数量，若已配置为S-SPS的UE的数量小于可配置总量，则确定分配给已配置为S-SPS的UE的S-SPS周期中最短者，并将两个以上周期时长中等于最短者的周期时长的下一个周期时长确定为待配置UE的S-SPS周期，将最短者对应的UE的S-SPS周期重配置为下一个周期时长。以图1所示的S-SPS周期和S-SPS资源块分配情况可知，假设分配给已配置为S-SPS的UE的S-SPS周期中最长者为n ms，有k个S-SPS资源块，那么可配置总量为n*k，若已配置为S-SPS的UE的数量小于该可配置总量，表示在现有配置下还可以增加S-SPS UE，基站设备需要对已配置为S-SPS的UE中的部分UE重新配置，从而空余出S-SPS资源块分配给待配置UE。示例性的，如图3所示，已配 置为S-SPS的UE包括UE1、UE2和UE3，其中，UE1的S-SPS周期为1ms，UE2和UE3的S-SPS周期为2ms，UE1独自占用一个S-SPS资源块，UE2和UE3轮流占用另一个S-SPS资源块，基站设备要给待配置UE(UE4)分配S-SPS周期和S-SPS资源块，可以将已配置的三个UE中S-SPS周期最短者(1ms)的下一个周期时长(2ms)确定为UE4的S-SPS周期，同时需要将已分配了1ms周期时长的UE1的S-SPS周期重配置为2ms，由UE1和UE4轮流占用一个S-SPS资源块，图5为本申请S-SPS资源分配的又一个示意图，基站设备给UE4分配了S-SPS周期和S-SPS资源块后如图5所示。需要说明的是，若分配给已配置为S-SPS的UE的S-SPS周期中最短者已经是S-SPS周期中的最长时长(例如图1中的5ms)，此时就不能再将最短者对应的UE的S-SPS周期重配置为下一个周期时长。
四、若已配置为S-SPS的UE的数量等于可配置总量，则将两个以上周期时长中等于分配给已配置为S-SPS的UE的S-SPS周期的周期时长的下一个周期时长确定为待配置UE的S-SPS周期，将分配给已配置为S-SPS的UE的其中一个或多个的S-SPS周期重配置为下一个周期时长。以图1所示的S-SPS周期和S-SPS资源块分配情况可知，假设分配给已配置为S-SPS的UE的S-SPS周期中最长者为n ms，有k个S-SPS资源块，那么可配置总量为n*k，若已配置为S-SPS的UE的数量已到达该可配置总量，表示所有已配置为S-SPS的UE的S-SPS周期均为n ms，且已没有S-SPS资源块未分配，基站设备需要扩大分配给已配置为S-SPS的UE的S-SPS周期，并对已配置为S-SPS的UE中的部分UE重新配置，从而空余出S-SPS资源块分配给待配置UE。示例性的，如图5所示，已配置为S-SPS的UE包括UE1、UE2、UE3和UE4，其中，UE1、UE2、UE3和UE4的S-SPS周期均为2ms，UE1和UE4轮流占用一个S-SPS资源块，UE2和UE3轮流占用另一个S-SPS资源块，基站设备要给待配置UE(UE5)分配S-SPS周期和S-SPS资源块，可以将UE1和UE4(或者UE2和UE3)的S-SPS周期的下一个周期时长(3ms)确定为UE5的S-SPS周期，同时需要将已分配了2ms周期时长的UE1和UE4的S-SPS周期重配置为3ms，由UE1、UE4和UE5轮流占用一个S-SPS资源块，图6为本申请S-SPS资源分配的再一个示意图，基站设备给UE5分配了S-SPS周期和S-SPS资源块后如图6所示。
步骤103、根据待配置UE的S-SPS周期给待配置UE分配S-SPS资源块。
基站设备可以根据待配置UE的S-SPS周期确定待配置UE的调度时刻，然后从其调度时刻上未分配的S-SPS资源块中给待配置UE分配S-SPS资源块。除此之外，基站设备还需要给待配置UE分配MCS，基站设备可以根据信道条件分配MCS，但由于S-SPS UE在激活期间其信道可能会发生波动，而MCS在整个激活期内不会再次调整，因此基站设备可以适当将MCS选的保守一些。该过程在步骤102中已举例描述，此处不再赘述。
本申请通过根据已配置为S-SPS的UE的S-SPS周期和S-SPS资源块自适应调整待配置UE的S-SPS周期，灵活配置通信网络中的S-SPS UE的资源，无需额外的信令开销，减少干扰，提高S-SPS效率。
在一种可能的实现方式中，基站设备可以进行多用户多输入多输出(Multi-User Multiple-Input and Multiple-Output，简称：MU-MIMO)配对，即将同一个S-SPS资源块分配给两个以上S-SPS UE，基站设备通过无线资源控制(Radio Resource Control，简称：RRC)消息给UE分配不同的循环移位(Cyclic Shift，简称：CS)，这样UE就可以复用相同的S-SPS资源块。基站设备可以根据空间自由度确定一个S-SPS资源块最多可以分配给多少 个S-SPS UE。示例性的，如图5所示，已配置为S-SPS的UE包括UE1、UE2、UE3和UE4，其中，UE1、UE2、UE3和UE4的S-SPS周期均为2ms，UE1和UE4轮流占用一个S-SPS资源块，UE2和UE3轮流占用另一个S-SPS资源块，基站设备要给待配置UE(UE5和UE6)分配S-SPS周期和S-SPS资源块，可以将UE5分别和UE1、UE4，UE6分别和UE2、UE3进行MU-MIMO配对，UE5和UE6的S-SPS周期为1ms，图7为本申请S-SPS资源分配的第五个示意图，基站设备给UE5和UE6分配了S-SPS周期和S-SPS资源块后如图7所示。或者，基站设备要给待配置UE(UE5、UE6、UE7和UE8)分配S-SPS周期和S-SPS资源块，可以将UE5和UE1、UE6和UE4，UE7和UE2、UE8和UE3分别进行MU-MIMO配对，UE5、UE6、UE7和UE8的S-SPS周期为2ms，图8为本申请S-SPS资源分配的第六个示意图，基站设备给UE5、UE6、UE7和UE8分配了S-SPS周期和S-SPS资源块后如图8所示。需要说明的是，基站设备进行MU-MIMO配对并不限于示例中的两个UE配对。
本申请通过对两个以上S-SPS UE进行MU-MIMO配对，提高资源利用率。
在一种可能的实现方式中，基站设备给待配置UE分配了S-SPS资源后，当该UE被激活就可以按照S-SPS资源的配置结果进行调度，但如果该UE上报的BSR中显示该UE的缓存数据量较大，仅靠一个S-SPS资源块毕竟资源有限，很难在短时间内将上行数据传输完毕，基站设备就会对该UE去激活，转而对其进行动态调度。此时，就会有S-SPS资源块被空下来，基站设备可以对其他S-SPS UE进行重新配置，包括重新配置其他S-SPS UE的S-SPS周期，例如，将S-SPS周期从2ms重配置为1ms，再在新的S-SPS周期对应的调度时刻上分配S-SPS资源块。相应的，如果基站设备发现该UE的缓存数据量下降，又可以对其进行重新激活或者重新配置。
图9为本申请用于短周期半静态调度的资源配置装置实施例一的结构示意图，如图9所示，本实施例的装置可以包括：确定模块11和分配模块12，其中，确定模块11，用于确定当前已配置为短周期半静态调度S-SPS的用户设备UE，并获取分配给所述已配置为S-SPS的UE的S-SPS周期和S-SPS资源块；分配模块12，用于根据所述分配给所述已配置为S-SPS的UE的S-SPS周期和S-SPS资源块确定待配置UE的S-SPS周期，所述待配置UE为支持S-SPS的UE；根据所述待配置UE的S-SPS周期给所述待配置UE分配S-SPS资源块。
