下面结合附图对本申请所提供的基于非码本的PUSCH接收/发送信息的方法及其装置进行详细地介绍。
请参见图2,图2是本申请实施例提供的一种基于非码本的PUSCH接收信息的方法的流程示意图。该基于非码本的PUSCH接收信息的方法由终端设备执行。如图2所示,该方法可以包括但不限于如下步骤:
步骤S21,向网络设备发送非码本的SRS资源集合中经过预编码的SRS资源。
本申请实施例中,终端设备可以支持最大PUSCH传输可以增加至8层,进而可以用于支持与下行可比的更高的上行传输速率。
本申请实施例中,探测参考信号(Sounding Reference Signal,SRS)资源集合中包括至少一个SRS资源。SRS资源可以为单端口的SRS资源,也可以为多端口的SRS资源。多端口的SRS资源配置的端口数量最大为8个。单端口的SRS资源时,SRS资源集合中最大配置8个SRS资源。
可选地,SRS资源集合的资源配置类型为:
第一类型:SRS资源集合包括多个第一候选SRS资源,其中,第一候选SRS资源均为单端口SRS资源。
第二类型:SRS资源集合包括至少一个第二候选SRS资源,不同的第二候选SRS资源有不同数量 的端口。例如,第二候选SRS资源1,端口数量为1,第二候选SRS资源2,端口数量为2,第二候选SRS资源3,端口数量为3,第二候选SRS资源4,端口数量为4,依次类推,第二候选SRS资源8,端口数量为8。
第三类型:所述SRS资源集合包括一个第三候选SRS资源,所述第三候选SRS资源配置有多个候选端口。端口数量的取值可以包括1,2,3,4,5,6,7,8。
可选地,网络设备通过高层信令向终端设备配置一个功能为非码本的SRS资源集合。例如,网络设备可以通过无线资源控制(Radio Resource Control,RRC)信令或媒体接入控制-控制单元(Media access control-Control Element,MAC-CE)信令或其他高层信令向终端设备配置该SRS资源集合。可选地,通过RRC信令实现SRS资源集合的配置或重配置,通过MAC-CE信令实现对于某个SRS资源集合的全部或部分SRS资源的更新配置。
可选地,SRS资源集合的时域特性为周期性、半持续或者非周期性,也就是说SRS资源集合可以为一个周期性SRS资源集合,或者为一个半持续SRS资源集合,或者为一个非周期性SRS资源集合。
本申请实施例中,终端设备在获取到网络设备配置的SRS资源集合后,可以基于初始预编码矩阵,对SRS资源集合中配置的SRS资源进行预编码,向网络设备发送采用预编码的SRS资源。预编码的SRS资源可以用于获取信道状态信息(Channel State Information,CSI),进而获取信道估计信息,该信道估计信息可以反映信道条件、预调度用户的干扰情况和/或信道噪声等调度信息。
需要说明的是,非码本上行传输方案也是一种空间复用技术,它与基于码本的上行传输的区别在于它的预编码基于一定的准则获得,而非基于固定的码本在有限的候选值中确定预编码。若上下行信道的互易性存在,则终端可以基于信道互易性进行下行信道信息的计算,从而获得上行预编码矩阵。若信道互易性足够好,终端通过下行信道可以获得更为准确的预编码,相对于基于码本的传输方案,可以节省预编码指示的开销,同时获得更好的性能。
可选地,终端设备接收网络设备配置的关联的下行信道状态信息参考信号(Channel State Information-Reference Signal,CSI-RS)资源,终端设备可以基于下行CSI-RS资源确定出初始预编码矩阵,本申请中PUSCH实际传输所使用的目标预编码矩阵是从初始预编码矩阵中筛选出的。
步骤S22,接收网络设备发送的指示信息,其中,指示信息用于指示PUSCH传输使用的预编码矩阵对应的TRI。
可选地,网络设备可以接收到预编码SRS资源进行信道估计,获取信道估计信息,由于信道估计信息可以反映出信道条件、预调度多用户的干扰情况和/或信道噪声,进而可以基于信道估计信息确定出终端设备的TRI。也就是说,网络设备可以综合考虑估计的上行信道信息、预调度用户的干扰情况等调度因素,从为终端设备配置的SRS资源集合中确定出PUSCH实际传输使用的第一资源组合,基于第一资源组合可以确定出目标预编码矩阵,以及基于第一资源组合内资源的数量确定出目标预编码矩阵对应的数据传输层数,即网络设备基于预编码的SRS资源,从SRS资源集合中选出第一资源组合,并且确定出PUSCH传输使用的预编码矩阵,以及预编码矩阵对应的TRI。
可选地,通过SRS资源的指示信息(Sounding Reference Signal ResourceIndicator,SRI)作为指示信息,通过该SRI指示TRI。可选地,指示信息也可以直接为TRI。
步骤S23,基于TRI,通过候选数据传输层与候选资源组合之间的第一映射关系,确定TRI对应的第一资源组合,其中,第一资源组合为基于预编码的SRS资源从SRS资源集合中确定,该第一资源组合包括一个或多个SRS资源的SRS资源组合或者,该第一资源组合为一个SRS资源的端口组合。

其中,第一资源组合为包括一个或多个SRS资源的SRS资源组合,或者为同一个SRS资源的端口组合。
