Description

上行数据传输方法及相关设备 技术领域
本申请涉及通信技术领域，具体涉及一种上行数据传输方法及相关设备。
背景技术
在新空口(NR，New radio)中，一个载波可以包含多个带宽部分(Bandwidth Part，BWP)。对于一个用户设备(User Equipment，UE)来说，在一个时刻只有一个上行BWP可以被激活用于上行传输。同样的，在一个时刻只有一个下行BWP可以被激活用于下行传输。用户设备当前被激活哪个BWP是通过下行控制信息(Downlink Control Information，DCI)指示的，用户设备传输所使用的BWP是可以在一个载波内的多个BWP中动态切换的。如果物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输可以在多个BWP上动态切换，那么如何传输PUSCH的参数配置是需要解决的技术问题。

所述用户设备确定所述上行BWP对应的PUSCH传输参数；
所述用户设备根据所述PUSCH传输参数在所述上行BWP上传输所述PUSCH。
第二方面，本申请实施例提供一种用户设备，包括处理单元和通信单元，其中：
所述处理单元，用于确定用于传输PUSCH的上行BWP；
所述处理单元，还用于确定所述上行BWP对应的PUSCH传输参数；
所述处理单元，还用于根据所述PUSCH传输参数通过所述通信单元在所述上行BWP上传输所述PUSCH。
第三方面，本申请实施例提供一种用户设备，包括一个或多个处理器、一个或多个存储器、一个或多个收发器，以及一个或多个程序，所述一个或多个程序被存储在所述存储器中，并且被配置由所述一个或多个处理器执行，所述程序包括用于执行如第一方面所述的方法中的步骤的指令。
第四方面，本申请实施例提供一种计算机可读存储介质，其存储用于电子数据交换的计算机程序，其中，所述计算机程序使得计算机执行如第一方面所述的方法所描述的部分或全部步骤。
第五方面，本申请实施例提供一种计算机程序产品，所述计算机程序产品包括存储了计算机程序的非瞬时性计算机可读存储介质，所述计算机程序可操作来使计算机执行如第一方面所述的方法所描述的部分或全部步骤。该计算机程序产品可以为一个软件安装包。
可见，本申请中，首先，网络设备可以给用户设备的每个BWP分别配置一套PUSCH传输参数；然后，在用户设备被动态切换到某个BWP上传输所述PUSCH的情况下，用户设备可将该某个BWP对应的PUSCH传输参数作为PUSCH传输所用的PUSCH传输参数；最后，用户设备基于该某个BWP对应的PUSCH传输参数在该某个BWP上传输所述PUSCH。这样可实现在不同BWP上传输所述PUSCH可以采用不同的PUSCH传输参数，进而提升了传输PUSCH的灵活性。
本申请的这些方面或其他方面在以下实施例的描述中会更加简明易懂。

图1示出了本申请涉及的无线通信***。所述无线通信***不限于长期演进(Long Term Evolution，LTE)***，还可以是未来演进的第五代移动通信(the 5th Generation，5G)***、新空口(NR)***，机器与机器通信(Machine to Machine，M2M)***等。如图1所示，无线通信***100可包括：一个或多个网络设备101和一个或多个用户设备102。其中：
网络设备101可以为基站，基站可以用于与一个或多个用户设备进行通信，也可以用于与一个或多个具有部分用户设备功能的基站进行通信(比如宏基站与微基站，如接入点，之间的通信)。基站可以是时分同步码分多址(Time Division Synchronous Code Division Multiple Access，TD-SCDMA)***中的基站收发台(Base Transceiver Station，BTS)，也可以是LTE***中的演进型基站(Evolutional Node B，eNB)，以及5G***、新空口(NR)***中的基站。另外，基站也可以为接入点(Access Point，AP)、传输节点(Trans TRP)、中心单元(Central Unit，CU)或其他网络实体，并且可以包括以上网络实体的功能中的一些或所有功能。
用户设备102可以分布在整个无线通信***100中，可以是静止的，也可以是移动的。在本申请的一些实施例中，终端102可以是移动设备、移动台(mobile station)、移动单元(mobile unit)、M2M终端、无线单元，远程单元、用户代理、移动客户端等等。
具体的，网络设备101可用于在网络设备控制器(未示出)的控制下，通过无线接口103与用户设备102通信。在一些实施例中，所述网络设备控制器可以是核心网的一部分，也可以集成到网络设备101中。网络设备101与网络设备101之间也可以通过回程(blackhaul)接口104(如X2接口)，直接地或者间接地，相互通信。
在NR现有的讨论中，一个载波可以包含多个BWP。对于一个用户设备102来说，在一个时刻只有一个上行BWP可以被激活用于上行传输。在一个时刻只有一个下行BWP可以被激活用于下行传输。用户设备102当前被激活哪个BWP是网络设备101通过DCI指示的，用户设备102传输所使用的BWP是可以在一个载波内的多个BWP中动态切换的。如果PUSCH传输可以在多个BWP上动态切换，那么如何传输PUSCH的参数配置是需要解决的技术问题。
可见，本申请中，首先，网络设备101可以给用户设备102的每个BWP分别配置一套PUSCH传输参数；然后，在用户设备102被动态切换到某个BWP上传输PUSCH的情况下，用户设备102可将该某个BWP对应的PUSCH传输参数作为PUSCH传输所用的 PUSCH传输参数；最后，用户设备102基于该某个BWP对应的PUSCH传输参数在该某个BWP上传输PUSCH。这样可实现在不同BWP上传输PUSCH可以采用不同的PUSCH传输参数，进而提升了传输PUSCH的灵活性。
需要说明的，图1示出的无线通信***100仅仅是为了更加清楚的说明本申请的技术方案，并不构成对本申请的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请提供的技术方案对于类似的技术问题，同样适用。

请参见图4，图4为本申请实施例提供的一种上行数据传输方法的流程示意图，包括以下步骤：
步骤401：用户设备确定用于传输PUSCH的上行BWP。
在本申请的一实施例中，在用户设备被动态切换到某一BWP上传输上述PUSCH的情况下，执行上述步骤401。
在本申请的一实施例中，上述步骤401的具体实现方式有：
用户设备根据BWP指示信息确定用于传输上述PUSCH的上行BWP，用于调度PUSCH传输的DCI包含上述BWP指示信息。
具体地，网络设备先通过高层信令给用户设备预先配置多个BWP，然后再通过DCI中的BWP指示信息指示这多个BWP中的其中一个BWP用于传输所述PUSCH。其中，高层信令可以包括无线资源控制协议(Radio Resource Control，RRC)信令，介质访问控制(Medium Access Control，MAC)信令等等。
举例来说，假设网络设备首先通过RRC信令预先给用户设备配置了4个BWP和这4个BWP对应的带宽，然后网络设备再通过DCI，该DCI包括2比特的BWP指示信息，这2比特的BWP指示信息用来指示其中用于传输所述PUSCH的BWP。比如，假设这4个BWP为BWP1、BWP2、BWP3和BWP4，假如这2比特的BWP指示信息为00，那么当前用于传输所述PUSCH的上行BWP为BWP1，又假如这2比特的BWP指示信息为11，那么当前用于传输所述PUSCH的上行BWP为BWP4，以此类推。
在本申请的一实施例中，DCI可以同时用于触发激活的上行BWP上的非周期SRS传输。
步骤402：用户设备确定上述上行BWP对应的PUSCH传输参数。
在本申请的一实施例中，所述方法还包括：
用户设备接收网络设备发送的高层信令，该高层信令用于为用户设备的每个上行BWP配置对应的PUSCH传输参数；
上述步骤402的具体实现方式有：
用户设备根据该高层信令确定上述上行BWP对应的PUSCH传输参数。
其中，该高层信息可以包括RRC信令，MAC信令等等。
具体地，网络设备先通过一高层信令预先给用户设备配置了4个BWP对应的带宽，然后再通过另一高层信令为这4个BWP分别配置对应的PUSCH传输参数。或者，网络设备仅通过一高层信令预先给用户设备配置了4个BWP对应的带宽以及为这4个BWP分别配置对应的PUSCH传输参数。
举例来说，这4个BWP为BWP1、BWP2、BWP3和BWP4，假设网络设备通过高层信令给BWP1配置PUSCH传输参数1、网络设备给BWP2配置PUSCH传输参数2、网络设备给BWP3配置PUSCH传输参数3、网络设备给BWP4配置PUSCH传输参数4。假如上述用于传输上述PUSCH的上行BWP为BWP1，那么用户设备根据该高层信令可得到BWP1对应的PUSCH传输参数为PUSCH传输参数1，以此类推。

在上述DCI包含上述TRI信息和上述TPMI信息的情况下，用户设备根据确定的上述TRI信息和上述TPMI在上述上行BWP上传输所述PUSCH。
具体地，假如上述上行传输方式为基于码本的传输，表示上述DCI中包含TRI信息和TPMI信息，用户设备需要根据上述TRI信息和上述TPMI信息确定所述PUSCH的传输层数和所用的预编码矩阵，然后再根据确定的传输层数和所用的预编码矩阵在所述上行BWP上传输所述PUSCH。
又假如上述上行传输方式为基于非码本的传输，表示上述DCI中不包含TRI信息和TPMI信息，用户设备需要根据上述DCI中的SRI指示信息来确定所述PUSCH的传输层数和所用的预编码矩阵，然后再根据确定的传输层数和所用的预编码矩阵在所述上行BWP上传输所述PUSCH。

用户设备根据上述DCI中包含的PMI信息，从上述目标码本子集中确定传输所述PUSCH所用的预编码矩阵；
用户设备根据确定的上述预编码矩阵在所述上行BWP上传输所述PUSCH。
举例来说，假设约定的码本可以得到3个码本子集，比如码本子集1、码本子集2和码本子集3，分别对应于全相关，部分相关和非相关三种UE天线相关能力。假如码本子 集约束配置指示码本子集1，那么用户设备将码本子集1确定为目标码本子集。假设目标码本子集包括4个预编码矩阵，这4个预编码矩阵有预编码矩阵1、预编码矩阵2、预编码矩阵3和预编码矩阵4。假如PMI信息指示预编码矩阵4，那么用户设备将预编码矩阵4确定为传输所述PUSCH所用的预编码矩阵。最后用户设备根据预编码矩阵4在所述上行BWP上传输所述PUSCH。
在本申请的一实施例中，上述PUSCH传输参数包括上行最大传输层数，用户设备根据上述PUSCH传输参数和上述DCI中包含的调度信息，在上述上行BWP上传输所述PUSCH的具体实现方式有：

用户设备根据上述频率选择性预编码配置和上述DCI中包含的PMI信息确定，传输所述PUSCH所用的预编码矩阵；
用户设备根据确定的上述预编码矩阵在上述上行BWP上传输所述PUSCH。
具体地，上述频率选择性预编码配置包含是否允许频率选择性预编码的指示信息，表示用户设备根据该是否允许频率选择性预编码的指示信息，确定上述DCI中包含的PMI信息是用于指示带宽PMI还是子带PMI；然后用户设备根据该PMI指示信息包含的宽带PMI或子带PMI，从约定的码本中确定预编码矩阵，确定的预编码矩阵用于在上述上行BWP上传输PUSCH。例如，如果所述指示信息指示允许频率选择性预编码，则终端确定上述DCI中包含的PMI信息是用于指示子带PMI；如果所述指示信息指示不允许频率选择性预编码，则终端确定上述DCI中包含的PMI信息是用于指示宽带PMI。
上述频率选择性预编码配置包含频率选择性预编码所用的子带大小或数量配置，表示用户设备根据该频率选择性预编码所用的子带大小或数量配置，确定上述DCI中包含的PMI信息所指示的子带PMI；然后用户设备根据该子带PMI从约定的码本中确定各个子带上的预编码矩阵，确定的各个子带上的预编码矩阵用于在上述上行BWP上传输所述PUSCH。
在本申请的一实施例中，上述PUSCH传输参数包括是否允许频率选择性预编码的指示信息，用户设备根据上述PUSCH传输参数和上述DCI中包含的调度信息，在上述上行BWP上传输所述PUSCH的具体实现方式有：
用户设备根据上述DCI中包含的SRI信息和上述是否允许频率选择性预编码的指示信息，确定是否需要对所述PUSCH中的数据进行频率选择性预编码；
用户设备根据确定的结果在上述上行BWP上传输所述PUSCH。
具体地，假如上述DCI中包含的SRI指示信息所指示的SRS资源的端口数大于或等于4，那么用户设备根据上述是否允许频率选择性预编码的指示信息，确定是否需要对所述PUSCH中的数据进行频率选择性预编码。最后用户设备基于确定的结果在上述上行BWP上传输所述PUSCH，比如确定的结果是需要对所述PUSCH中的数据进行频率选择性预编码，那么用户设备在传输所述PUSCH之前，先对所述PUSCH中的数据进行频率选择性预编码，然后再传输所述PUSCH，以此类推。比如确定的结果是不需要对所述PUSCH中的数据进行频率选择性预编码，那么用户设备在传输所述PUSCH之前，先对所述PUSCH中的数据进行宽带预编码，然后再传输所述PUSCH，以此类推
又假设上述DCI中包含的SRI信息所指示的SRS资源的端口数小于4，那么用户设 备确定不需要对所述PUSCH中的数据进行频率选择性预编码，只要对所述PUSCH中的数据进行宽带预编码，然后再传输所述PUSCH。
