下面结合附图对本申请所提供的基于非码本的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。该基于非码本的PUSCH发送信息的方法由网络设备执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤S21，接收终端设备发送的非码本的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；或者
第二类型：SRS资源集合包括一个第二候选SRS资源，其中，第二候选SRS资源有多个候选端口。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)信令或媒体介入控制层控制单元(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资源应用初始预编码矩阵，向网络设备发送预编码的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、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传输技术，它与基于码本的上行传输的区别在于它的预编码不限于固定的码本，可以基于一定的准则获得，如信道互易性特性，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关联的下行信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)资源，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，本申请中PUSCH传输使用的预编码矩阵是从初始预编码矩阵中筛选出的。

步骤S23，基于第一资源组合内SRS资源的标识或SRS资源的端口的标识，生成位图指示信息。
可选地，位图中包括候选SRS资源或候选端口对应的比特位，可选地，候选SRS资源或候选端口的编号，按照从小到大的顺序分别对应位图中最高比特位至最低位比特位，也就是说，第i个SRS资源对应位图中第i个比特，或者，第i个端口对应位图中第i个比特。
网络设备基于第一资源组合内SRS资源或端口的标识，配置位图上每个比特位的取值，在取值配置完成后，生成位图指示信息。例如，可以将选中的SRS资源或端口对应的比特位置1，未选中的SRS资源或端口对应的比特位置0，生成位图指示信息。
本申请实施例中，位图指示信息还可以用于向终端设备指示PUSCH传输使用的预编码矩阵对应的TRI。例如可以获取到位图指示信息中取值为1的比特位数，确定出预编码矩阵对应的TRI。
步骤S24，向终端设备发送位图指示信息。
可选地，通过SRI将位图指示信息发送给终端设备，或者通过高层信令直接向终端设备发送位图指示信息，例如网络设备通过RRC信令或者MAC-CE信令或者其他高层信令，向终端设备指示指示信息。
需要说明的时，第一资源组合内选择的SRS资源需要应用高层配置的最大传输层数RANK作为码本子集限制，也就是说，PUSCH传输使用的预编码矩阵对应的数据传输层数，小于或者等于该终端设备所支持的最大数据传输层数。
本申请实施例中，接收终端设备发送的非码本的SRS资源集合对应的预编码SRS资源，基于预编码SRS资源，从SRS资源集合中选出资源组合，基于选出的资源组合内SRS资源或端口的标识，生成位图指示信息，其中，位图指示信息用于指示PUSCH传输使用的预编码矩阵。本申请实施例中，通过位图指示信息，就可以能够确定出满足PUSCH传输要求的预编码矩阵，无需依赖预先定义SRI映射表，在数据传输层增加的场景下，通过位图指示信息就可以指示支持8层的PUSCH传输的预编码矩阵。
