Description

一种信息指示方法以及装置
本申请要求于2021年4月6日提交中国国家知识产权局、申请号为202110369029.7、发明名称为“一种信息指示方法以及装置”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
本申请实施例涉及通信领域，尤其涉及一种信息指示方法以及装置。
背景技术
终端设备在物理上行共享通道(physical uplink shared channel，PUSCH)上向网络设备发送数据时，终端设备可以在不同时域的正交频分复用技术(orthogonalfrequency division multiplexing，OFDM)符号上采用不同的预编码矩阵分别向多个不同的网络设备发送数据。通过多个不同的网络设备协作接收终端设备在PUSCH上发送的数据，可以提升终端设备的上行性能。
网络设备预先配置多个SRS资源集合，终端设备基于SRS资源集合生成发送波束用于发送PUSCH。现有技术中，无法支持动态选择适当的SRS资源集合。由于信道质量是时变的，某个SRS资源集合可能不适合生成发送波束用于发送PUSCH，若仍然基于多个SRS资源集合生成发送波束，会造成网络资源的浪费，有效指示用于生成发送波束的SRS资源集合的数量以适配当前传输信道条件是一个亟待解决的问题。
发明内容
本申请提供了一种信息指示方法以及装置，终端设备可以根据DCI确定资源集合的数量，进而，在PUSCH上使用一个或多个资源集合对应的发送波束传输数据。该方法中，终端设备根据适合生成发送波束的资源集合传输数据，节约了网络资源，提升了通信效率。
本申请第一方面提供了一种信息指示方法，终端设备接收网络设备发送的下行控制信息DCI，所述DCI中包括第一探测参考信号指示SRI字段和第二SRI字段，所述第一SRI字段的值包括第一类字段值和第二类字段值，所述第二SRI字段的值包括第三类字段值，所述第一类字段值和所述第三类字段值用于指示资源集合中包括的探测参考信号(Sounding Reference Signal，SRS)的标识，所述第二类字段值用于指示所述资源集合的标识；所述终端设备根据所述DCI在物理上行共享通道PUSCH上使用一个或多个所述资源集合对应的发送波束传输数据。
本申请中，终端设备接收的DCI中包括第一SRI字段和第二SRI字段，第一SRI字段的值包括第一类字段值和第二类字段值，第二SRI字段的值包括第三类字段值，第一类字段值和第三类字段值可以用于指示资源集合中包括的SRS的标识，第二类字段值用于指示资源集合的标识。终端设备可以根据DCI确定资源集合的数量，进而，在PUSCH上使用一个或多个资源集合对应的发送波束传输数据。该方法中，终端设备根据适合生成发送波束 的资源集合传输数据，节约了网络资源，提升了通信效率。
在第一方面的一种可能的实现方式中，所述资源集合包括第一资源集合和第二资源集合，若所述第一SRI字段的值为所述第一类字段值，所述第一类字段值用于指示所述第一资源集合中的SRS的标识，所述第三类字段值用于指示所述第二资源集合中SRS的标识。
该种可能的实现方式中，若第一SRI字段的取值为第一类字段值，即第一SRI字段指示SRS资源集合0中的一个SRS资源时，第二SRI字段的取值为第三类字段值，第三类字段值指示了SRS资源集合1中的一个SRS资源。终端设备根据DCI中的第一SRI字段和第二SRI字段可以确认终端设备需要选择SRS资源集合0和SRS资源集合1中的资源在PUSCH上传输上行数据，即该终端设备在PUSCH上传输的上行数据由网络设备1和网络设备2共同接收，以便于实现上行分集增益，进一步提升终端设备的通信质量。
在第一方面的一种可能的实现方式中，所述资源集合包括第一资源集合和第二资源集合，所述第二类字段值包括第一值和第二值，若所述第一SRI字段的值为所述第一值，所述第三类字段值用于指示所述第一资源集合中SRS的标识，若所述第一SRI字段的值为所述第二值，所述第三类字段值指示所述第二资源集合中SRS的标识。
该种可能的实现方式中，当第一SRI字段的值为第一值时，代表第一SRI字段指示了SRS资源集合0。此时，第二SRI字段中的第三类字段值分别指示了SRS资源集合0中的SRS资源0和SRS资源1。终端设备根据第一SRI字段选择了与网络设备1对应的SRS资源集合0，根据第二SRI字段选择了SRS资源集合0中的SRS资源0或SRS资源1向网络设备1传输上行数据。当第一SRI字段的值为第二值时，代表第一SRI字段指示了SRS资源集合1。此时，第二SRI字段中的第三类字段值分别指示了SRS资源集合1中的SRS资源0和SRS资源1。终端设备根据第一SRI字段选择了与网络设备2对应的SRS资源集合1，根据第二SRI字段选择了SRS资源集合1中的SRS资源0或SRS资源1向网络设备2传输上行数据。该种可能的实现方式中，网络设备可以灵活地指示终端设备通过合适的网络设备传输上行数据，避免了不适合传输数据的网络设备接收终端设备发送的上行数据，提高了网络资源的利用率。
本申请第二方面提供了一种信息指示方法，终端设备接收网络设备发送的下行控制信息DCI，所述DCI中包括第一传输预编码矩阵指示TPMI字段和第二TPMI字段，所述第一TPMI字段包括第一类字段值和第二类字段值，所述第二TPMI字段包括第三类字段值，所述第一类字段值和所述第三类字段值用于指示资源集合中的资源对应的TPMI，所述第二类字段值用于指示终端设备在物理上行共享通道PUSCH上使用一个资源集合对应的发送波束传输数据；所述终端设备根据所述DCI在所述PUSCH上使用一个或多个资源集合对应的发送波束传输数据。
本申请中，终端设备接收的DCI中包括第一TPMI字段和第二TPMI字段，DCI中包括第一TPMI字段，第一TPMI字段包括第一类字段值和第二类字段值，第二TPMI字段包括第三类字段值，第一类字段值和第三类字段值用于指示资源集合中的资源对应的TPMI，第二类字段值用于指示终端设备在物理上行共享通道PUSCH上使用一个资源集合对应的发送波束传输数据。由于资源集合与网络设备一一对应，终端设备便可以根据DCI确定资源 集合的数量，进而，在PUSCH上使用一个或多个资源集合对应的发送波束向一个或多个网络设备传输数据。
在第二方面的一种可能的实现方式中，所述资源集合包括第一资源集合和第二资源集合，若所述第一TPMI字段的值为所述第一类字段值，所述第一类字段值用于指示所述第一资源集合中的资源对应的TPMI，所述第三类字段值用于指示所述第二资源集合中的资源对应的TPMI。
该种可能的实现方式中，若第一TPMI字段的取值为第一类字段值，即第一TPMI字段指示与SRS资源集合0中的一个SRS资源对应的预编码矩阵，第二TPMI字段的取值为第三类字段值，第三类字段值指示了SRS资源集合1中的一个SRS资源对应的预编码矩阵。终端设备根据DCI中的第一TPMI字段和第二TPMI字段可以确认终端设备需要选择SRS资源集合0和SRS资源集合1中的资源在PUSCH上传输上行数据，即该终端设备在PUSCH上传输的上行数据由网络设备1和网络设备2共同接收，以便于实现上行分集增益，进一步提升终端设备的通信质量。
在第二方面的一种可能的实现方式中，所述资源集合包括第一资源集合和第二资源集合，若所述第一TPMI字段的值为所述第二类字段值，SRI字段或TPC字段用于确定所述一个资源集合的标识，所述第三类字段值指示所述一个资源集合中的资源对应的TPMI。
该种可能的实现方式中，若第一TPMI字段的取值为第二类字段值，第一TPMI字段的取值指示reserved，则第一TPMI字段指示终端设备只使用一个SRS资源集合对应的发送波束向一个网络设备发送上行数据。具体选择哪一个SRS资源集合可以解读SRI字段或发送功率指令(Transmission Power Command，TPC)字段。该种可能的实现方式中，网络设备可以灵活地指示终端设备通过合适的网络设备传输上行数据，避免了不适合传输数据的网络设备接收终端设备发送的上行数据，提高了网络资源的利用率。
在第二方面的一种可能的实现方式中，所述第三类字段值还用于指示所述PUSCH的传输层数。
该种可能的实现方式中，通过第一TPMI字段指示终端设备是通过一个或多个资源集合向网络设备发送上行数据时，为了节约网络资源，第一TPMI字段可以仅指示TPMI而不指示传输层数(rank)，第二TPMI字段中的第三类字段值可以同时指示传输层数和TPMI(rank+TPMI)，且第一TPMI字段的rank遵从第二TPMI的指示。例如，若第二TPMI字段指示了1层(layer)，则第一TPMI字段指示的TPMI也是1 layer。本申请中，之所以选择第一TPMI字段指示终端设备是通过一个或多个资源集合向网络设备发送上行数据，是因为第二TPMI字段可以包括rank+TPMI的指示，而第一TPMI字段仅包括TPMI的指示。

该种可能的实现方式中，当第一SRI字段的值为第一值时，代表第一SRI字段指示了SRS资源集合0。此时，第二SRI字段中的第三类字段值分别指示了SRS资源集合0中的SRS资源0和SRS资源1。终端设备根据第一SRI字段选择了与网络设备1对应的SRS资源集合0，根据第二SRI字段选择了SRS资源集合0中的SRS资源0或SRS资源1向网络设备1传输上行数据。当第一SRI字段的值为第二值时，代表第一SRI字段指示了SRS资源集合1。此时，第二SRI字段中的第三类字段值分别指示了SRS资源集合1中的SRS资源0和SRS资源1。终端设备根据第一SRI字段选择了与网络设备2对应的SRS资源集合1，根据第二SRI字段选择了SRS资源集合1中的SRS资源0或SRS资源1向网络设备2传输上行数据。该种可能的实现方式中，网络设备可以灵活地指示终端设备通过合适的网络设备传输上行数据，避免了不适合传输数据的网络设备接收终端设备发送的上行数据，提高了网络资源的利用率。
在第四方面的一种可能的实现方式中，所述第三类字段值还用于指示所述PUSCH的传输层数。
该种可能的实现方式中，通过第一TPMI字段指示终端设备是通过一个或多个资源集合向网络设备发送上行数据时，为了节约网络资源，第一TPMI字段可以仅指示TPMI而不指示传输层数(rank)，第二TPMI字段中的第三类字段值可以同时指示传输层数和TPMI(rank+TPMI)，且第一TPMI字段的rank遵从第二TPMI的指示。例如，若第二TPMI字段 指示了1 layer，则第一TPMI字段指示的TPMI也是1 layer。本申请中，之所以选择第一TPMI字段指示终端设备是通过一个或多个资源集合向网络设备发送上行数据，是因为第二TPMI字段可以包括rank+TPMI的指示，而第一TPMI字段仅包括TPMI的指示。
本申请第五方面提供一种通信装置，该通信装置包括至少一个处理器，处理器用于执行该指令，该指令在被处理器执行时，使得所述终端设备执行上述第一方面或第一方面的任意可能的实现方式中的方法，或，使得所述终端设备执行上述第二方面或第二方面的任意可能的实现方式中的方法。

具体实施方式
下面结合附图，对本申请提供的示例进行描述，显然，所描述的示例仅仅是本申请一部分的示例，而不是全部的示例。本领域普通技术人员可知，随着技术的发展和新场景的出现，本申请提供的技术方案对于类似的技术问题，同样适用。

终端设备在物理上行共享信道(physical uplink shared channel，PUSCH)上向网络设备发送数据时，终端设备可以在不同时域的正交频分复用技术(orthogonal frequency division multiplexing，OFDM)符号上采用不同的预编码矩阵分别向多个不同的网络设备发送数据。通过多个不同的网络设备协作接收终端设备在PUSCH上发送的数据，可以提升终端设备的上行性能。
网络设备预先配置多个SRS资源集合，终端设备基于SRS资源集合生成发送波束用于发送PUSCH。现有技术中，无法支持动态选择适当的SRS资源集合。由于信道质量是时变的，某个SRS资源集合可能不适合生成发送波束用于发送PUSCH，若仍然基于多个SRS资源集合生成发送波束，会造成网络资源的浪费，有效指示用于生成发送波束的SRS资源集合的数量以适配当前传输信道条件是一个亟待解决的问题。
为了解决上述方案中存在的问题，本申请中提供了一种信息指示方法以及相关设备，终端设备接收的DCI中包括第一SRI字段和第二SRI字段，第一SRI字段的值包括第一类字段值和第二类字段值，第二SRI字段的值包括第三类字段值，第一类字段值和第三类字段值可以用于指示资源集合中包括的SRS的标识，第二类字段值用于指示资源集合的标识。终端设备可以根据DCI确定资源集合的数量，进而，在PUSCH上使用一个或多个资源集合对应的发送波束传输数据。该方法中，终端设备根据适合生成发送波束的资源集合传输数据，节约了网络资源，提升了通信效率。
本申请还提供了一种信息指示系统，该信息指示系统可以应用于同构网络或异构网络。该信息指示系统可以应用于频分双工(frequency division duplexing，FDD)系统或者时分双工系统。该信息指示系统可以应用于低频场景(sub 6G)，也可以用于高频场景(6G以上)。该信息指示系统可以应用于4G、5G或未来的移动通信系统。具体此处不做限定。
图1为本申请提供的一种信息指示系统的应用示意图。
请参阅图1，本申请提供的信息指示系统包括终端设备101、网络设备102和/或网络设备103。
本申请提供的信息指示系统中，终端设备101可以向网络设备102和/或网络设备103传输上行数据，终端设备传输上行数据时有两种上行传输方式，分别是基于码本的上行传输与基于非码本的上行传输，下面对两种传输方式分别进行介绍。
(1)基于码本的上行传输。
本申请中，以终端设备101向网络设备102发送上行数据为例来阐述基于非码本的上行传输过程。首先，假设网络设备102向终端设备101分配了资源集合A，资源集合A与网络设备102一一对应，终端设备101采用资源集合A中的SRS向网络设备102发送消息。网络设备102根据终端设备发送的SRS进行信道测量，选择出其中最优的SRS生成SRI与TPMI。该SRI指示了该最优的SRS资源的索引值，该TPMI指示了该最优的SRS资源上传输SRS对应的发送天线用于传输上行数据时所使用的预编码矩阵，也就是说，上行数据传输的发送波束是基于SRI和TPMI指示信息联合确定的。终端设备101可以根据该SRI中指示的索引值以及TPMI中指示的预编码矩阵在PUSCH上向网络设备102传输上行数据。 此时，我们可以说，该PUSCH或者该PUSCH的发送波束对应了SRI指示的SRS资源。
(2)基于非码本的上行传输。
本申请中，以终端设备101向网络设备103发送上行数据为例来阐述基于非码本的上行传输过程。基于非码本的上行传输利用了上下行信道之间的互异性，终端设备101向网络设备103传输上行数据时没有预定义码本。终端设备101对网络设备103发送的下行信号进行测量，确定至少一个候选的预编码。假设网络设备103向终端设备101分配了资源集合B，终端设备101采用资源集合B中的SRS通过多个候选的预编码向网络设备103发送消息。其中，一个SRS对应一个候选预编码，网络设备103从接收到的多个SRS中选择出最优的SRS，并通过SRI将该最优的SRS的索引值指示给终端设备101。终端设备101根据SRI可以确定出该最优的SRS的索引值以及与该最优的SRS对应的发送预编码矩阵，进而在PUSCH上向网络设备103发送上行数据。
本申请中，该终端设备101可以接收网络设备102和/或网络设备103发送的DCI。可选的，DCI中可以包括第一探测参考信号指示SRI字段和第二SRI字段，第一SRI字段的值包括第一类字段值和第二类字段值，第二SRI字段的值包括第三类字段值，第一类字段值和第三类字段值用于指示SRS资源集合中包括的SRS的标识，第二类字段值用于指示资源集合的标识。可选的，DCI中可以包括第一传输预编码矩阵指示(Transmission Precoding Matrix Indication，TPMI)字段和第二TPMI字段。第一TPMI字段包括第一类字段值和第二类字段值，第二TPMI字段包括第三类字段值，第一类字段值和第三类字段值用于指示SRS资源集合中的资源对应的TPMI，第二类字段值用于指示终端设备在PUSCH上使用一个SRS资源集合对应的发送波束传输数据。本申请中，终端设备101可以根据DCI确定终端设备所使用的资源集合的数量，进而，终端设备101可以根据DCI在PUSCH上使用一个或多个资源集合对应的发送波束向网络设备102和/或网络设备103传输数据。
本申请中，可选的，图1仅以一个终端设备和两个网络设备为例进行示意性说明。实际应用中，本申请提供的信息指示系统还可以包括比图1中所示的更多的终端设备和网络设备，本申请对终端设备以及网络设备的数目不进行限定。

本申请中，上述示例中信息指示系统中所提及的终端设备可以是指向用户提供语音和 /或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。终端设备可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与网络设备交换语言和/或数据。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)等设备。终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端(remote terminal)、接入终端(access terminal)、用户代理(user agent)、用户设备(user device)、或用户装备(user equipment)、用户站、远方站、用户终端(terminal equipment，TE)、终端、无线通信设备以及用户代理或用户装置。另外，终端设备也可以是用于实现UE功能的芯片系统。具体此处不做限定。
本申请提供的信息指示系统中，终端设备接收的DCI中包括第一SRI字段和第二SRI字段，第一SRI字段的值包括第一类字段值和第二类字段值，第二SRI字段的值包括第三类字段值，第一类字段值和第三类字段值可以用于指示资源集合中包括的SRS的标识，第二类字段值用于指示资源集合的标识。终端设备可以根据DCI确定资源集合的数量，进而，在PUSCH上使用一个或多个资源集合对应的发送波束向一个或多个网络设备传输数据，节约了网络资源。

表18 第二SRI字段
通过第一TPMI字段指示终端设备是通过一个或多个资源集合向网络设备发送上行数据时，为了节约资源，第一TPMI字段可以仅指示TPMI而不指示传输层数(rank)，第二TPMI字段中的第三类字段值可以同时指示传输层数和TPMI(rank+TPMI)，且第一TPMI字段的rank遵从第二TPMI的指示。例如，若第二TPMI字段指示了1 layer(比特0或者1)，则第一TPMI字段指示的TPMI也是1 layer。本申请中，之所以选择第一TPMI字段指示终端设备是通过一个或多个资源集合向网络设备发送上行数据，是因为第二TPMI字段可以包括rank+TPMI的指示，而第一TPMI字段仅包括TPMI的指示。从而，第一TPMI字段可以携带额外的指示信息用于指示终端设备是通过一个还是多个SRS资源集合向网络设备发送上行数据。本申请提供的两种信息指示方法可以应用与切换场景中，当网络设备由单站接收切换为多站接收时，网络设备可以向终端设备发送与场景1中所描述的DCI相类似的DCI指示终端设备在PUSCH上向多个网络设备发送上行数据。当网络设备由多站接收切换为单站接收时，网络设备可以向终端设备发送与场景2中所描述的DCI相类似的DCI指示终端设备在PUSCH上向单个网络设备发送上行数据。
本申请中，可选的，上述方法示例中提及的SRI字段、TPMI字段和/或TPC字段的比特值可以选择除上述表格中展示之外的其他值。且各字段中包括的比特值并没有顺序关系。例如，请参阅表19，表1中SRI字段的比特值可以是0、1、2、3之外的其他值，比如5、8、12、6等其他值，具体此处不做限定。
