Description

一种信道质量信息处理方法及装置 技术领域
本公开涉及但不限于无线通信技术，尤指一种信道质量信息处理方法及装置。
背景技术
随着第四代(4G，the 4th Generation mobile communication technology)移动通信系统的持续发展，大规模多输入多输出(Massive MIMO，Massive Multiple Input Multiple Output)技术将成为提升网络容量的一项重要技术。
在频分双工(FDD，Frequency Divided Duplex)制式下，上下行信道的离开角(DOA，Departure Of Angle)具有互易性。在Massive MIMO技术中，基站将小区按照DOA范围划分为多个预制波束覆盖，并且按照一定的策略从划分的多个预制波束中为终端选择激活预制波束，这样，基站可以通过激活预制波束向终端发送数据。激活预制波束无交集的终端可以空分复用相同的时频资源从而提高网络容量。
在FDD制式下，Massive MIMO技术策略中，由于小区中存在多个预制波束，而终端在特定时刻只有一个激活的预制波束，这样，对如传输模式9(TM9，Transmission Mode 9)的用户来讲，会导致基站向终端发送数据的波束(即激活的预制波束)与发送小区参考信号的波束(如小区多个预制波束)可能不同，这样会直接导致终端估计的下行信道质量如信道状态信息(CSI，Channel State Information)与实际数据发送的信道不匹配，从而影响了终端的解调性能。

附图说明
附图用来提供对本公开技术方案的进一步理解，并且构成说明书的一部分，与本公开的实施例一起用于解释本公开的技术方案，并不构成对本公开技术方案的限制。
图1为本公开信道质量信息处理方法的流程图；
图2为本公开信道质量信息处理装置的组成结构示意图。
具体实施方式
为使本公开的目的、技术方案和优点更加清楚明白，下文中将结合附图对本公开的实施例进行详细说明。需要说明的是，在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互任意组合。
TM9是在3GPP Rel-10中定义的一种传播模式，相较以往，TM9增加了新的信道状态信息-参考信号(CSI-RS，Channel State Information-Reference Signal)，负责用户级的信道测量/反馈。不同的用户可以有不同的CSI-RS配置，结合用户级导频的解调参考信号(DMRS，Demodulation Reference Signal)，可以一起形成针对用户的波束，达到波随人动的效果。同时，基站的波束可以从以往一个较胖的小区级波束变为多个较窄的用户级波束，不相干的波束可以组成配对，实现多用户MIMO(MU-MIMO)，从而复用频谱资源，提升网络容量。
但是，如果基站向终端发送数据的波束(即激活的预制波束)与发送小区参考信号的波束(如小区多个预制波束)可能不同，则会导致终端估计的下行信道质量如CSI与实际数据发送的信道不匹配，从而影响终端的解调性能。本公开提供的获取信道质量信息的方案，可以使得终端如TM9终端进行测量的参考信号如CSI-RS与终端本身的激活预制波束保持一致，从而能获得准确的信道质量，保证终端的解调性能，进而提升网络容量。
图1为本公开信道质量信息处理方法的流程图，如图1所示，包括：
步骤100：根据配置的发送参数确定信道质量参考信息在预制波束上 周期发送的波束集合。
本步骤之前还包括：
将小区按照DOA范围划分为多个预制波束覆盖，每个预制波束对应一个DOA范围。预制波束之间交叠要求足够小。其中，预制波束覆盖的DOA范围宽度与基站的天线个数有关，基站天线越多，则预制波束覆盖的DOA范围宽度可以越窄。
可选地，发送参数包括但不限于：信号发送周期和周期内的偏移量。
可选地，本步骤包括：
按照配置的信号发送周期和在周期内的偏移量计算发送信道质量参考信息的无线帧号(FrameNo CSI-RS)和子帧号(SubFrameNo CSI-RS)；
根据小区的预制波束和计算出的发送信道质量参考信息的无线帧号和子帧号，确定波束集合中的每个信道质量参考信息发送周期对应的预制波束。这样，可以实现信道质量参考信息按照波束集合中的预制波束周期滚动发送。
可选地，确定波束集合中的每个信道质量参考信息发送周期对应的预制波束包括：按照预先设置的周期发送策略确定发送信道质量参考信息对应的预制波束BF j，使得信道质量参考信息在预制波束上周期发送。
下面结合实例对周期发送策略进行举例说明。
比如：将信道质量参考信息与预制波束的编号从小到大的顺序对应，则发送信道质量参考信息对应的预制波束BF j为：
当SubFrameNo CSI-RS小于5时，BF j＝(FrameNo CSI-RS<<1)mod BF NUM；
当SubFrameNo CSI-RS大于或等于5时，BF j＝((FrameNo CSI-RS<<1)+1)mod BF NUM；其中，mod表示取模运算，<<表示左移。
又如：将信道质量参考信息与预制波束的编号从小到大的顺序对应，则发送信道质量参考信息对应的预制波束BF j为：
BF j＝(FrameNo CSI-RS/(I CSI-RS/10))mod BF NUM；其中，Mod表示取模运 算。
再如：将信道质量参考信息与预制波束对应，对应关系为先对应所有偶数编号(按照从小到大的顺序)的预制波束，再对应所有奇数编号(按照从小到大的顺序)的预制波束。这样，发送信道质量参考信息对应的预制波束BF j为：
当SubFrameNo CSI-RS小于5时，BF j＝((FrameNo CSI-RS<<1)mod BF NUM)×2；
当SubFrameNo CSI-RS大于或等于5时，BF j＝(((FrameNo CSI-RS<<1)+1)mod BF NUM)×2+1；其中，mod表示取模运算，<<表示左移。
上述实例并不用于限定周期发送策略的实现，只要按照预先设置的周期发送策略确定发送信道质量参考信息对应的预制波束BF j使得信道质量参考信息在预制波束上周期发送即可。
可选地，在FDD Massive MIMO场景下，信道质量参考信息为CSI-RS信号。
以信道质量参考信息为CSI-RS为例，本步骤具体包括：按照配置的CSI-RS信号发送周期I CSI-RS和在周期内的偏移量Δ CSI-RS计算发送CSI-RS的子帧号；根据小区的预制波束和计算出的发送CSI-RS的子帧号，确定每个CIS-RS发送周期对应的预制波束，这些预制波束形成波束集合。这样，就可以实现小区CSI-RS信号按照波速集合中的预制波束遍历发送的目的。也就是说，基站将小区的CSI-RS信号在确定出的波束集合中的预制波束进行遍历发送，即每隔CSI-RS发送周期周期性下发对应预制波束的CSI-RS信号。
步骤101：确定终端的激活预制波束。
可选地，终端可以包括但不限于如TM9终端。
可选地，本步骤中的确定终端的激活预制波束包括：
通过终端如TM9终端上行探测信号估计上行信道，按照设置的激活策略从预制波束中选择终端的激活预制波束。
可选地，由于上下行信道的DOA具有互易性，设置的激活策略可以包括但不限于：分别计算上行信道在各预制波束的投影能量，将最大的投影能量对应的预制波束作为该终端的激活预制波束。
可选地，当存在多个对应最大的投影能量的预制波束时，可以取其中一个波束如波束编号小的波束作为该终端的激活预制波束。
需要说明的是，本公开中的步骤100与步骤101之间并没有严格的先后执行顺序。
步骤102：从确定出的波束集合中选择与激活预制波束一致的波束作为上报信道质量信息的波束。
按照终端的激活预制波束，从得到的波束集合中查找与激活预制波束相同的发送小区信道参考质量信息的波束，将查找出的波束作为触发终端上报信道质量信息的波束即根据预制波束触发了终端非周期性的信道质量信息上报。此时，终端上报的非周期性的信道质量信息是根据当前激活的预制波束对应的相同预制波束的信道质量参考信息信号测量计算得到的，因此，基站得到了准确的信道质量信息用于后续调度，实现对终端的波束域空分复用，从而提升了网络容量。
可选地，如果由于下行物理控制信道(PDCCH，Physical Downlink Control Channel)资源不够或者其他原因等，不能触发该终端的非周期性的信道质量信息的上报，则丢弃此次触发机会即不执行此时上报的步骤，等下一次再触发上报对应查找到的预制波束的信道质量参考信息。
以信道质量信息为CSI-RS为例，如果由于PDCCH资源不够或者其他原因等，如果计算得到的CSI-RS下发子帧无法下发触发非周期CSI的DCI0格式，则丢弃此次触发机会，等下一次对应该预制波束的CSI-RS信号，目的是保证该终端的非周期性CSI必须是对应该终端的预制波束的CSI-RS信道测量得到的。由于终端上报的周期性CSI信息不一定是对应该终端的预制波束CSI-RS信号测量的结果，因此，调度过程中会使用本公开非周期性上报的CSI信息。
本公开实施例中，对小区的信道质量参考信息如CSI-RS信号按照预制波束进行遍历发送，匹配小区信道质量参考信息如CSI-RS信号的预制波束，触发终端对应预制波束的非周期性的信道质量信息如CSI的上报。通过在选择出的波束上触发信道质量信息的上报，确保了终端如TM9终端进行测量的信道质量参考信号如CSI-RS所在的预制波束与终端本身的激活预制波束是一致的，这样，必然获得了准确的信道质量，从而保证了终端的解调性能，进而提升了网络容量。
本发明实施例还提供一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令用于执行上述任一项所述的实现信道质量信息处理的方法。
本发明实施例还提供一种实现信道质量信息处理的设备，包括处理器、存储器；其中，存储器上存储有可在处理器上运行的计算机程序：用于执行上述任一项实现信道质量信息处理的方法的步骤。
图2为本公开信道质量信息处理装置的组成结构示意图，如图2所示，至少包括：第一确定模块、第二确定模块，处理模块；其中，

可选地，本公开装置还包括：预处理模块，设置为将小区按照DOA范围均匀划分为多个预制波束覆盖，每个预制波束对应一个DOA范围。
可选地，发送参数包括但不限于：信号发送周期和周期内的偏移量。
可选地，第一确定模块具体设置为：
按照配置的信号发送周期和在周期内的偏移量计算发送信道质量参考信息的子帧号；根据小区的预制波束和计算出的发送信道质量参考信息 的子帧号，确定波束集合中每个信道质量擦没考信息发送周期对应的预制波束。
可选地，在FDD Massive MIMO场景下，信道质量参考信息为CSI-RS信号。
可选地，第二确定模块具体设置为：
通过终端上行探测信号估计上行信道，按照设置的策略从预制波束中选择终端的激活预制波束。
可选地，由于上下行信道的DOA具有互易性，设置的策略可以包括但不限于：分别计算上行信道在各预制波束的投影能量，将最大的投影能量对应的预制波束作为该终端的激活预制波束。
可选地，终端可以包括但不限于如TM9终端。
可选地，处理模块具体设置为：
按照终端的激活预制波束，从得到的波束集合中查找与激活预制波束相同的发送小区信道质量信息的波束，将查找出的波束作为上报信道质量信息的波束。
可选地，如果由于下行物理控制信道(PDCCH，Physical Downlink Control Channel)资源不够或者其他原因等，不能触发该终端的非周期性信道质量信息的上报，那么，处理模块还设置为：丢弃此次触发机会即不执行此次上报的步骤，等下一次再触发上报对应查找到的预制波束的信道质量信息。
本公开实施例中，对小区的信道质量参考信息如CSI-RS信号按照预制波束进行遍历发送，匹配小区信道质量参考信息如CSI-RS信号的预制波束，触发终端对应预制波束的非周期性的信道质量信息如CSI的上报。通过在选择出的波束上触发信道质量信息的上报，确保了终端如TM9终端进行测量的信道质量参考信号如CSI-RS所在的预制波束与终端本身的激活预制波束是一致的，这样，必然获得了准确的信道质量，从而保证了终端的解调性能，进而提升了网络容量。
下面以FDD Massive MIMO场景为例，详细描述本公开实现信道质量信息处理方法。
第一实施例
假设将小区按照DOA范围划分为7个预制波束覆盖，编号分别为0-6。
一方面，按照配置的发送CSI-RS的发送参数计算CSI-RS发送子帧，其中，CSI-RS的配置参数包括：发送周期I CSI-RS和在周期内的偏移量Δ CSI-RS。
第一实施例中，假设I CSI-RS取值为5，Δ CSI-RS取值为1，计算得到：无线帧号(FrameNo CSI-RS)为0，子帧号(SubFrameNo CSI-RS)为1时发送CSI-RS信号，下一次发送CSI-RS信号为无线帧号为0，子帧号为6时，依次类推，每隔I CSI-RS周期如5ms发送CSI-RS信号。
第一实施例中，预制波束的数量BF NUM为7个波束，编号为0-6，本实施例中，将CSI-RS信号与预制波束从小到大的顺序对应，则发送CSI-RS对应的预制波束BF j为：
当SubFrameNo CSI-RS小于5时，BF j＝(FrameNo CSI-RS<<1)mod BF NUM；
当SubFrameNo CSI-RS大于或等于5时，BF j＝((FrameNo CSI-RS<<1)+1)mod BF NUM；其中，mod表示取模运算，<<表示左移。
按照上述计算方法，当帧号为0，子帧号为1时，对应需要发送的预制波束的编号为0；当帧号为0，子帧号为6时，对应发送的预制波束的编号为1，依次类推，一直循环轮流发送小区预制波束对应的CSI-RS信号。
另一方面，根据终端在各个预制波束上的投影能量P i，并按照下面公式确定该终端的激活预制波束i：
i＝max(P 0，P 1，...，P N)         (1)
其中，i＝0～6；N＝6，max表示取最大值运算；第一实施例中，假设P 0、P 1、P 2、P 3、P 4、P 5、P 6的能量分别为800、12000、600、300、200、180、100，那么，按照公式(1)容易确定出该终端的激活预制波束的编号为 1。
根据确定出的终端的激活预制波束i即编号为1的预制波束，在每个CSI-RS信号发送周期匹配CSI-RS发送的预制波束，当CSI-RS发送的预制波束为1时，触发终端的非周期性CSI上报。第一实施例中，在帧号为0，子帧号为6时触发终端的非周期性CSI上报。
这样，保证了终端上报的周期性CSI信息对应的是该终端的预制波束CSI-RS信号测量的结果，因此，按照本公开方法得到的终端上报的非周期性CSI信息是可以用于后续调度的。
第二实施例
假设将小区按照DOA范围划分为7个预制波束覆盖，编号分别为0-6。
一方面，按照配置的发送CSI-RS的发送参数计算CSI-RS发送子帧，其中，CSI-RS的配置参数包括：发送周期I CSI-RS和在周期内的偏移量Δ CSI-RS。
第二实施例中，假设I CSI-RS取值为10，Δ CSI-RS取值为2，计算得到：无线帧号为0，子帧号为2时发送CSI-RS信号，下一次发送CSI-RS信号为无线帧号为1，子帧号为2时，依次类推，每隔I CSI-RS周期如10ms发送CSI-RS信号。
第二实施例中，预制波束的数量BF NUM为7个波束，编号为0-6，将CSI-RS信号与预制波束从小到大的顺序对应，则发送CSI-RS对应的预制波束BF j为：
BF j＝(FrameNo CSI-RS/(I CSI-RS/10))mod BF NUM；其中，Mod表示取模运算。
按照上述计算方法，当帧号为0，子帧号为2时，对应需要发送的预制波束的编号为0；当帧号为1，子帧号为2时，对应发送的预制波束的编号为1，依次类推，一直循环轮流发送小区预制波束对应的CSI-RS信号。
另一方面，根据终端在各个预制波束上的投影能量P i，并按照公式(1)确定该终端的激活预制波束i：
第二实施例中，假设P 0、P 1、P 2、P 3、P 4、P 5、P 6的能量分别为12000、12000、600、300、200、180、100，那么，按照公式(1)容易确定出该终端的激活预制波束的编号为0。需要说明的是，本实施例中有两个波束的能量都为最大值，那么，可以取波束编号小的波束作为该终端的激活预制波束，第二实施例中即为编号为0的预制波束。需要说明的是，这里也可以选编号大的，只要从中用一个波束作为该终端的激活预制波束即可，具体选哪个并没有限制。
根据确定出的终端的激活预制波束i即编号为0的预制波束，在每个CSI-RS信号发送周期匹配CSI-RS发送的预制波束，当CSI-RS发送的预制波束为0时，触发终端的非周期性CSI上报。第二实施例中，在帧号为0，子帧号为2时触发终端的非周期性CSI上报。
这样，保证了终端上报的周期性CSI信息对应的是该终端的预制波束CSI-RS信号测量的结果，因此，按照本公开方法得到的终端上报的非周期性CSI信息是可以用于后续调度的。
第三实施例
假设将小区按照DOA范围划分为11个预制波束覆盖，编号分别为0-10。
一方面，按照配置的发送CSI-RS的发送参数计算CSI-RS发送子帧，其中，CSI-RS的配置参数包括：发送周期I CSI-RS和在周期内的偏移量Δ CSI-RS。
第三实施例中，假设I CSI-RS取值为5，Δ CSI-RS取值为1，计算得到：无线帧号为0，子帧号为1时发送CSI-RS信号，下一次发送CSI-RS信号为无线帧号为0，子帧号为6时，依次类推，每隔I CSI-RS周期如5ms发送CSI-RS信号。
第三实施例中，预制波束的数量BF NUM为11个波束，编号为0-10，本实施例中，将CSI-RS信号与预制波束对应，对应关系为先对应所有偶数编号(从小到大的顺序)的预制波束，再对应所有奇数编号(从小到大的顺序)的预制波束。这样，发送CSI-RS对应的预制波束BF j为：
当SubFrameNo CSI-RS小于5时，BF j＝((FrameNo CSI-RS<<1)mod BF NUM)×2；
当SubFrameNo CSI-RS大于或等于5时，BF j＝(((FrameNo CSI-RS<<1)+1)mod BF NUM)×2+1；其中，mod表示取模运算，<<表示左移。
按照上述计算方法，当帧号为0，子帧号为1时，对应需要发送的预制波束的编号为0；当帧号为0，子帧号为6时，对应发送的预制波束的编号为1，依次类推，一直循环轮流发送小区预制波束对应的CSI-RS信号。
另一方面，根据终端在各个预制波束上的投影能量P i，并按照公式(1)确定该终端的激活预制波束i：
第三实施例中，假设P 0、P 1、P 2、P 3、P 4、P 5、P 6的能量分别为2000、2000、600、300、200、10080、100、300、200、1280、500，那么，按照公式(1)容易确定出该终端的激活预制波束的编号为5。
根据确定出的终端的激活预制波束i即编号为5的预制波束，在每个CSI-RS信号发送周期匹配CSI-RS发送的预制波束，当CSI-RS发送的预制波束为5时，触发终端的非周期性CSI上报。第三实施例中，在帧号为4，子帧号为1时触发终端的非周期性CSI上报。
这样，保证了终端上报的周期性CSI信息对应的是该终端的预制波束CSI-RS信号测量的结果，因此，按照本公开方法得到的终端上报的非周期性CSI信息是可以用于后续调度的。
第四实施例
假设将小区按照DOA范围划分为11个预制波束覆盖，编号分别为0-10。
一方面，按照配置的发送CSI-RS的发送参数计算CSI-RS发送子帧，其中，CSI-RS的配置参数包括：发送周期I CSI-RS和在周期内的偏移量Δ CSI-RS。
第四实施例中，假设I CSI-RS取值为10，Δ CSI-RS取值为2时，计算得到：无线帧号为0，子帧号为2时发送CSI-RS信号，下一次发送CSI-RS信号 为无线帧号为1，子帧号为2时，依次类推，每隔I CSI-RS周期如10ms发送CSI-RS信号。
第四实施例中，预制波束的数量BF NUM为11个波束，编号为0-10，本实施例中，将CSI-RS信号与预制波束从小到大的顺序对应，则发送CSI-RS对应的预制波束BF j为：
BF j＝(FrameNo CSI-RS/(I CSI-RS/10))mod BF NUM；其中，Mod表示取模运算。
按照上述计算方法，当帧号为0，子帧号为2时，对应需要发送的预制波束的编号为0；当帧号为1，子帧号为2时，对应发送的预制波束的编号为1，依次类推，一直循环轮流发送小区预制波束对应的CSI-RS信号。
另一方面，根据终端在各个预制波束上的投影能量P i，并按照公式(1)确定该终端的激活预制波束i：
第四实施例中，假设P 0、P 1、P 2、P 3、P 4、P 5、P 6的能量分别为2000、2000、600、300、200、1080、100、300、200、12800、500，那么，按照公式(1)容易确定出该终端的激活预制波束的编号为9。
根据确定出的终端的激活预制波束i即编号为9的预制波束，在每个CSI-RS信号发送周期匹配CSI-RS发送的预制波束，当CSI-RS发送的预制波束为9时，触发终端的非周期性CSI上报。第二实施例中，在帧号为9，子帧号为2时触发终端的非周期性CSI上报。
但是，本实施例中，如果在调度时由于本终端的优先级比较低，在分配资源时没有分配到触发DCI的资源，无法触发非周期CSI上报，那么，按照本公开实施例，此时不触发此终端的非周期性CSI上报，等待I CSI-RS×BF NUM个子帧后，CSI-RS发送的预制波束的编号再次为9时，再触发该终端的非周期性CSI上报。
这样，保证了终端上报的周期性CSI信息对应的是该终端的预制波束CSI-RS信号测量的结果，因此，按照本公开方法得到的终端上报的非周 期性CSI信息是可以用于后续调度的。
以上所述，仅为本发明的较佳实例而已，并非用于限定本发明的保护范围。凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
