下面结合附图对本申请所提供的一种基于非码本的PUSCH发送/接收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发送信息的方法的流程示意图。如图2所示，该方法由网络设备执行，可以包括但不限于如下步骤：
步骤S21，响应于终端设备支持最大的物理上行共享信道PUSCH传输层数增加至8层，基于终端设备所支持的最大上行数据传输层数L max，对已有的第一探测参考信号资源指示信息SRI映射表进行扩展，得到第二SRI映射表。
本申请实施例中，将终端设备的上行数据传输层数增加至8层，也就是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。本申请实施例中第一上行数据传输层为单终端原有支持的PUSCH共享信道传输对应的上行数据传输层，第二上行数据传输层为在原有的第一上行数据传输层基础上，新增加的上行数据传输层。比如，原有的PUSCH对应的上行数据传输层为1-4层，1-4层为第一上行数据传输。本公开中新增加到了8层，则第二上行数据传输层为5层到8层。该定义适用于本公开全部实施例。
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)信令或者媒体接入控制-控制单元(Media access control-Control Element，MAC-CE)向终端设备配置该非码本的SRS资源集合。可选地，可以通过RRC配置或重配置，也可以通过MAC-CE更新部分或全部配置。
可选地，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，SRS资源集合中一个或多个单端口的SRS资源。
每一个第一上行数据传输层对应有第一SRI映射表，该SRI映射表中包括SRI索引值与SRS资源组合之间的对应关系，即SRI索引值可以索引到对应的SRS资源组合，其中，SRS资源组合中包括网络设备配置给终端设备的SRS资源集合中的一个或多个SRS资源。
本申请实施例中，最大的物理上行共享信道PUSCH传输层数增加至8层，则终端设备所支持的最大上行数据传输层数L max＝8，现有的第一SRI映射表并未覆盖上行数据传输第5层至第8层，为了能够支持最大8层的上传数据传输，需要对现有的第一SRI映射表进行扩展，以得到能够覆盖上行数据传输第5层至第8层，以支持最大8层的上传数据传输。
可选地，网络设备基于最大上行数据传输层数L max和已有的第一上行数据传输层数，确定新增的第二上行数据传输层数，以及向所述终端设备配置的探测参考信号SRS资源集合对应的配置数量集合，其中，配置数量集合包括SRS资源集合内配置的SRS资源的数量N SRS，本申请实施例中，当最大的物理上行共享信道PUSCH传输层数增加至8层时，SRS资源集合中可以配置的SRS数量N SRS，从可配置4个SRS资源增加到可以配置8个SRS资源。
进一步地，网络设备基于第二上行数据传输层数和配置数量集合，对所述第一SRI映射表进行扩展，得到可以覆盖上行数据传输第1层至第8层的第二SRI映射表。
作为一种可能的实现方式，基于最大上行数据传输层数L max和配置数量集合，可以对第一SRI映射表进行扩展，扩展出每个上行数据传输层数对应的一个SRI映射表，该扩展后的SRI映射表中包括配置数量集合中每个N SRS对应的SRS资源组合，以及SRS资源组合对应的索引值。也就是说，配置有8个SRI映射表，每个SRI映射表中包括N SRS＝1/2/3/4/5/6/7/8的情况下对应的SRS资源组合，及其对应的SRI索引值。需要说明的是，每个上行数据传输层数对应的扩展后的SRI映射表，即为一个第二SRI映射表。
作为另一种可能的实现方式，基于最大上行数据传输层数L max和配置数量集合，对第一SRI映射表进行扩展，扩展包括部分SRI映射关系的第二SRI映射表。在一些实现中，该第二SRI映射表中可以包括每个上行数据传输层数对应的全部SRI映射关系中部分内容。例如，可以从每个上行数据传输层数对应的扩展后的SRI映射表中选取部分，组成一个受限的第二SRI映射表。在另一些实现中，该第二SRI映射表中可以包括为其中一个上行数据传输层数对应的全部SRI映射关系中部分映射关系，即第二SRI映射表为其中一个上行数据传输层数对应部分映射关系组成的一个SRI映射子表，这样可以节约SRI指示的信令开销。
步骤S22，基于第二SRI映射表，向终端设备指示从SRS资源集合中测量得到的第一SRS资源组合，用于指示PUSCH传输所使用的预编码矩阵，第一SRS资源组合包括至少一个单端口SRS资源。
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)，进而获取可以获取到信道估计信息，该信道估计信息可以反映信道条件、多用户的干扰情况和/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，网络设备向终端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，并发给终端设备，相应地，终端设备可以基于下行CSI-RS资源确定出初始预编码矩阵。需要说明的是，本申请中PUSCH实际传输使用的预编码矩阵是从初始预编码矩阵中筛选出的。
相应地，网络设备可以接收到预编码的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、多用户的干扰情况和/或信道噪声，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SRS资源组合。进一步地网络设备基于第一SRS资源组合可以确定出PUSCH传输使用的预编码矩阵，以及基于第一SRS资源组合内资源的数量确定出预编码矩阵对应的TRI，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SRS资源组合，并且确定出PUSCH传输使用的预编码矩阵，以及PUSCH传输使用的预编码矩阵对应的TRI，该TRI可以指示PUSCH传输使用的第三上行数据传输层数。
网络设备可以基于第三上行数据传输层数，从第二SRI映射表中，确定与第三上行数据传输层数对应的SRI映射关系，并从该SRI映射关系中确定第一SRS资源组合对应的SRI索引值。网络设备通过该SRI索引值向终端设备指示第一SRS资源组合，以指示终端设备根据该第一SRS资源组合，确定出PUSCH实际传输使用的预编码矩阵。
本申请实施例中，基于最大上行数据传输层数L max，扩展现有的第一SRI映射表，使得扩展后的第 二SRI映射表，填充了新增的上行数据传输层数和新增的N SRS对应的SRI映射关系的空白，为增强上行发送能力提供了基础依据。而且能基于配置的第二SRI映射表，向终端设备指示PUSCH实际传输所需的预编码矩阵，有利于提供PUSCH的传输的安全性、可靠性和准确性，选取满足PUSCH传输要求的预编码矩阵，可以避免与其他被终端设备之间的资源冲突。

针对每个第一上行数据传输层数，扩展第二候选数量下SRI索引值与SRS资源组合之间的第一映射关系，基于第一映射关系对第一SRI映射表扩展，得到第二SRI映射表。也就是说，对于上行数据传输第1层至上行数据传输第4层，第一SRI映射表已经包括第一候选数量下SRI索引值与SRS资源组合之间的映射关系，即第一SRI映射表中已经包括N SRS＝1/2/3/4时SRI索引值与SRS资源组合之间的映射关系，本申请实施例中，对每个第一上行数据传输层数，扩展第二候选数量下SRI索引值与SRS资源组合之间的第一映射关系，即扩展N SRS＝5/6/7/8时SRI索引值与SRS资源组合之间的第一映射关系。如表1所示，表1中增加了第1层在N SRS＝5/6/7/8时SRI索引值与SRS资源组合之间的第一映射关系。

进一步地，基于第一映射关系对第一SRI映射表扩展，得到每个第一上行数据传输层数的第三SRI映射表，即第1层至第4层分别有各自的第三SRI映射表，也就是说将新增加的第一映射关系与现有的 第一SRI映射表中的映射关系进行组合，得到第三SRI映射表。本申请实施例中第三SRI映射表中包括N SRS＝1/2/3/4/5/6/7/8时对应的SRI索引值与SRS资源组合之间的映射关系。本申请实施例中实现了对已有的第一上行数据传输层数的第一SRI映射表的复用。
针对每个第二上行数据传输层数，扩展配置数量集合内每个候选数量下的SRI索引值与SRS资源组合之间的第二映射关系，并基于所述第二映射关系得到第四SRI映射表。也就是说，对于上行数据传输第5层至上行数据传输第8层，未存在已有的第一SRI映射表，需要为第5至8层，扩展配置每个候选数量下SRI索引值与SRS资源组合之间的第二映射关系，即扩展N SRS＝1/2/3/4/5/6/7/8时SRI索引值与SRS资源组合之间的第二映射关系。进一步地，基于第二映射关系对第一SRI映射表扩展，得到每个第二上行数据传输层数的第四SRI映射表，即第5层至第8层分别有各自的第四SRI映射表。
网络设备将第三SRI映射表和第四SRI映射表，确定为第二SRI映射表，即第二SRI映射表为一个集合包括每个第一上行数据传输层数扩展后的第二SRI映射表，还包括每个第二上行数据传输层数扩展后的第四SRI映射表，第二SRI映射表总数量为8个，与终端设备所支持的最大上行数据传输层数的取值相同。

步骤S36，从第三上行数据传输层数对应的SRI映射表中，确定第一SRS资源组合对应的SRI索引值，并将SRI索引值指示给终端设备。
其中，第三上行数据传输层数对应的SRI映射表中包括不同SRS资源组合与不同SRI索引值之间的映射关系，本申请实施例中，可以基于第一SRS资源组合，即第一SRS资源组合中SRS资源的编号和SRS资源集合对应的N SRS，从第三上行数据传输层数对应的SRI映射表中，确定出第一SRS资源组合对应的SRI索引值，并将SRI索引值指示给终端设备。可选地，通过SRI指示域，将SRI索引值指示给终端设备。
本申请实施例中，基于最大上行数据传输层数L max，扩展现有的第一SRI映射表，使得扩展后的第二SRI映射表，填充了新增的上行数据传输层数和新增的N SRS对应的SRI映射关系的空白，为增强上行发送能力提供了基础依据。而且能基于配置的第二SRI映射表，向终端设备指示PUSCH实际传输所需的预编码矩阵，有利于提供PUSCH的传输的安全性、可靠性和准确性，选取满足PUSCH传输要求的预编码矩阵，可以避免与其他被终端设备之间的资源冲突。

其中，第一SRS资源组合为从SRS资源集合中选出的SRS资源形成的组合，包括至少一个单端口的SRS资源。
终端设备通过高层信令从网络设备处获取一个功能为非码本的SRS资源集合，例如，终端设备可以接收RRC信令或者MAC-CE信令，从RRC信令或者MAC-CE信令获取网络设备为其配置的SRS资源集合，可选地，可以通过RRC配置或重配置，也可以通过MAC-CE更新部分或全部配置。
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，SRS资源集合中一个或多个单端口的SRS资源。
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CSI，进而获取可以获取到信道估计信息，该信道估计信息可以反映信道条件、多用户的干扰情况和/或信道噪声等调度信息。

请参见图7，图7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。如图7所示，该方法由终端设备执行，可以包括但不限于如下步骤：
步骤S71，响应于终端设备支持最大的物理上行共享信道PUSCH传输层数增加至8层，基于终端设备所支持的最大上行数据传输层数L max和已有的第一上行数据传输层数，确定新增的第二上行数据传输层数，以及向终端设备配置的SRS资源集合对应的配置数量集合。
需要说明的是，配置数量集合包括SRS资源集合内配置的SRS资源的数量N SRS，本申请实施例中，当最大的物理上行共享信道PUSCH传输层数增加至8层时，SRS资源集合中可以配置的SRS数量N SRS，从可配置4个SRS资源增加到可以配置8个SRS资源。即配置数量集合中包括已有的第一候选数量和新增的第二候选数量，其中，第一候选数量包括1至4，新增的第二候选数量包括5至8。
步骤S72，基于第二上行数据传输层数和配置数量集合，对第一SRI映射表进行扩展，得到第二SRI映射表。
针对每个第一上行数据传输层数，扩展第二候选数量下SRI索引值与SRS资源组合之间的第一映射关系，基于第一映射关系对第一SRI映射表扩展，得到第二SRI映射表。也就是说，对于上行数据传输第1层至上行数据传输第4层，第一SRI映射表已经包括第一候选数量下SRI索引值与SRS资源组合之间的映射关系，即第一SRI映射表中已经包括N SRS＝1/2/3/4时SRI索引值与SRS资源组合之间的映射关系，本申请实施例中，对每个第一上行数据传输层数，扩展第二候选数量下SRI索引值与SRS资源组合之间的第一映射关系，即扩展N SRS＝5/6/7/8时SRI索引值与SRS资源组合之间的第一映射关系。
进一步地，基于第一映射关系对第一SRI映射表扩展，得到每个第一上行数据传输层数的第三SRI映射表，即第1层至第4层分别有各自的第三SRI映射表，也就是说将新增加的第一映射关系与现有的第一SRI映射表中的映射关系进行组合，得到第三SRI映射表。本申请实施例中第三SRI映射表中包括N SRS＝1/2/3/4/5/6/7/8时对应的SRI索引值与SRS资源组合之间的映射关系。本申请实施例中实现了对已有的第一上行数据传输层数的第一SRI映射表的复用。
针对每个第二上行数据传输层数，扩展配置数量集合内每个候选数量下的SRI索引值与SRS资源组 合之间的第二映射关系，并基于所述第二映射关系得到第四SRI映射表。也就是说，对于上行数据传输第5层至上行数据传输第8层，未存在已有的第一SRI映射表，需要为第5至8层，扩展配置每个候选数量下SRI索引值与SRS资源组合之间的第二映射关系，即扩展N SRS＝1/2/3/4/5/6/7/8时SRI索引值与SRS资源组合之间的第二映射关系。进一步地，基于第二映射关系对第一SRI映射表扩展，得到每个第二上行数据传输层数的第四SRI映射表，即第5层至第8层分别有各自的第四SRI映射表。
终端设备将第三SRI映射表和第四SRI映射表，确定为第二SRI映射表，即第二SRI映射表为一个集合包括每个第一上行数据传输层数扩展后的第二SRI映射表，还包括每个第二上行数据传输层数扩展后的第四SRI映射表，第二SRI映射表总数量为8个，与终端设备所支持的最大上行数据传输层数的取值相同。

步骤S75，从第三SRI映射表和第四SRI映射表中，确定第三上行数据传输层数对应的SRI映射表。
本申请实施例中，第三SRI映射表和第四SRI映射表，分别对应不同的上行数据传输层数。在确定出第三上行数据传输层数后，可以基于从第三SRI映射表和第四SRI映射表中，确定出第三上行数据传输层数对应的SRI映射表。例如，第三上行数据传输层数为1，则可以将第1层对应的第二SRI映射表作为第三上行数据传输层数对应的SRI映射表。
步骤S76，从第三上行数据传输层数对应的SRI映射表中，确定基于SRI索引值索引的SRS资源组合，并确定第一SRS资源组合。
其中，第一SRS资源组合为从SRS资源集合中选出的SRS资源形成的组合，包括至少一个单端口的SRS资源。
其中，第三上行数据传输层数对应的SRI映射表中包括不同SRS资源组合与不同SRI索引值之间的映射关系，本申请实施例中，可以基于SRI索引值和SRS资源集合对应的N SRS，从第三上行数据传输层数对应的SRI映射表中，确定出SRI索引值对应的第一SRS资源组合。
步骤S77，基于第一SRS资源组合，确定PUSCH实际传输使用的预编码矩阵。
