Description

PUSCH重复传输方法及终端设备 技术领域
本发明涉及通信领域，尤其涉及一种PUSCH重复传输方法及终端设备，以及计算机可读存储介质。
背景技术
现有技术中，用于调度物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的下行控制信息(Downlink Control Information，DCI)中包含探测参考信号(Sounding Reference Signal，SRS)资源指示(Sounding Reference Signal Resource Indicator，SRS Resource Indicator，SRI)域和发送预编码矩阵指示(Transmit Precoding Matrix Indicator，TPMI)域，终端设备基于所指示的SRI和TPMI得到单个波束和预编码矩阵，从而用于PUSCH的传输。如果PUSCH被配置了重复传输，则不同的重复传输所用的发送波束和预编码矩阵是相同的，都是来自于所述SRI域和TPMI域。
为了利用多个传输接收点(Transmission and Reception Point，TRP)进一步提高上行传输的可靠性，新无线(New Radio，NR)引入了基于多个TRP的上行重复传输，即不同的重复传输可以发给不同的TRP，如图1所示，为一种实现方式中基于多TRP的PUSCH重复传输的一个示意图。由于不同TRP对应的信道是不同的，不同的重复传输需要采用与信道对应的传输参数(如发送波束和/或预编码矩阵)，以得到最好的传输性能。但是现有协议中SRI域和TPMI域只能得到单个波束和预编码矩阵，无法同时匹配两个TRP各自的信道，从而影响了上行传输的性能。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
下面先对本申请实施例涉及的术语进行简要说明，如下所示：
1、上行码本传输和非码本传输
终端设备发送上行数据(物理上行共享信道(Physical Uplink Shared Channel，PUSCH))时，需要对上行数据进行预编码处理，以获得上行预编码增益。预编码处理一般分为两个部分：模拟域处理和数字域处理。模拟域处理针对发送的模拟信号，一般采用波束赋形的方式把射频信号映射到物理天线上。数字域处理针对数字信号，一般在基带进行，采用预编码矩阵对数字信号进行预编码，将传输层的数据映射到射频端口上。由于终端设备的射频通道数量有限，一般要同时采用两种处理方式，即对数字信号进行预编码，再对模拟信号采用波束进行赋形。PUSCH传输根据预编码方式的不同，分为基于码本的传输和基于非码本的传输。
在上行基于码本的预编码方式中，网络侧会为终端设备配置一个专用于码本传输的探测参考信号(Sounding Reference Signal，SRS)资源集合。终端设备会在集合中的多个SRS资源上发送SRS，每个SRS资源上的SRS采用不同的波束，网络侧从中选择最好的SRS资源用于获得上行信道状态指示(Channel State Information，CSI)，同时将资源索引通过SRS资源指示(Sounding Reference Signal Resource Indicator，SRS Resource Indicator，SRI)指示给终端设备，令终端设备采用SRS资源相应的波束对数据进行模拟波束赋形。同时，网络侧会通过下行控制信息(Downlink Control Information，DCI)指示秩指示(Rank Indicator，RI)和发送预编码矩阵指示(Transmit Precoding Matrix Indicator，TPMI,也称为PMI)，终端设备根据RI和TPMI从码本中确定TPMI对应的上行的预编码矩阵。如图2所示，为一种实现方式中基于码本的PUSCH传输的一个示意图。
对于一些支持上下行信道互易性的终端设备，还可以支持基于非码本的预编码方式。终端设备可以利用下行信道信息来得到上行信道信息，从而进行上行的模拟波束赋形和/或数字预编码，此时网络侧不需要再指示预编码矩阵的相关信息，从而可以降低DCI的开销。具体的，网络侧先发送信道状态信息参考信号(Channel State Information Reference Signal，CSI Reference Signal，CSI-RS)，令终端设备基于CSI-RS确定N个layer的波束和预编码矩阵。终端设备采用这N个layer的波束和预编码矩阵来发送N个单端口的SRS资源(即N个SRS ports)，这N个SRS资源被配置为一个用于非码本传输的SRS资源集合。网络侧收到SRS资源后进行测量，选择其中最好的K个SRS资源并将相应的SRI指示给终端设备，终端设备根据SRI来确定所采用的传输层数、预编码矩阵和模拟波束。指示的SRS资源的数量即为传输层数，相应SRS资源采用的预编码矩阵和模拟波束即为数据相应layer采用的预编码矩阵 和波束。此时，DCI中不需要指示RI和PMI。如图3所示，为一种实现方式中基于非码本的PUSCH传输的一个示意图。
2、上行重复传输
为了提高PUSCH的传输可靠性，新无线(New Radio，NR)引入了PUSCH的重复传输，即携带相同数据的PUSCH通过不同的时频资源/天线/冗余版本等多次传输，从而获得分集增益，降低误检概率(BLER)。具体的，所述重复传输可以在不同时隙进行，如图4所示，为一种实现方式中基于时隙的PUSCH重复传输的一个示意图。可以在不同的正交频分复用(Orthogonal Frequency Division Multiple，OFDM)符号中进行，如图5所示，为一种实现方式中基于OFDM符号的PUSCH重复传输的一个示意图(时隙内或者跨时隙)。也可以在多个Panel(天线面板)上进行，如图6所示，为一种实现方式中基于多TRP/Panel的PUSCH重复传输的一个示意图。对于多时隙或者多符号的重复传输，一个DCI可以调度多个PUSCH在连续的多个时隙或者多个OFDM符号上传输，携带相同的数据但采用不同的冗余版本。此时，不同重复传输的接收端可以是相同的传输接收点(Transmission and Reception Point，TRP)或者不同的TRP。对于多Panel重复，携带相同数据的PUSCH同时在不同Panel上分别传输，接收端可以是同一个TRP也可以是不同的TRP。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、非授权频谱上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、非授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)系统、非地面通信网络(Non-Terrestrial Networks，NTN)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、第五代通信(5th-Generation，5G)系统或其他通信系统等。

用于不同的重复传输。
可选的，第二传输参数还可以包括发送功率等其他参数。
可选的，所述一个预编码矩阵的不同部分，可以对应不同的PUSCH发送功率或发送功率缩放系数。
可选的，所述终端设备根据所述一个预编码矩阵的不同部分，分别确定PUSCH的不同重复传输所使用的第三传输参数，可以包括：
所述终端设备根据所述PUSCH的一次重复传输对应的所述一个预编码矩阵的部分预编码矩阵，确定所述一次重复传输的发送功率或发送功率缩放系数。所述一个预编码矩阵的不同部分和发送功率(或发送功率缩放系数)的对应关系可以由终端和网络设备预先约定好，或者由网络设备预先通知给终端设备。
可选的，所述终端设备根据所述传输参数，分别进行所述PUSCH的多次重复传输，可以包括：终端设备根据所述第二传输参数，所述第二传输参数包括所述传输层数，和/或，所述预编码矩阵，分别进行所述PUSCH的多次重复传输。
例如，奇数次的重复传输和偶数次的重复传输使用所述第一预编码矩阵的不同部分进行预编码；或者，前两次重复传输和后两次重复传输使用所述第一预编码矩阵的不同部分进行预编码，以此类推。
在本发明实施例中，终端设备根据一个TPMI域所指示的一个预编码矩阵就可以得到两个预编码矩阵，用于不同的PUSCH重复传输，从而分别匹配与不同TRP之间的信道，提高上行多TRP分集传输的性能。
实现方式3：
所述第一信息为通过一个SRI域指示的两个SRI，每个SRI指示不同SRS资源集合中的一个SRS资源，所述终端设备根据所述两个SRI，分别确定PUSCH的不同重复传输所使用的第三传输参数，所述第三传输参数包括所述发送波束、所述天线端口和所述发送功率中的至少一个。
可以理解的是，每个SRI指示不同SRS资源集合中的一个SRS资源，即两个SRI中的第一SRI用于指示第一SRS资源集合中的一个SRS资源(称为第一SRS资源)，第二SRI用于指示第二SRS资源集合中的一个SRS资源(称为第二SRS资源)。所述第一SRS资源集合和第二SRS资源集合可以预先配置给终端设备。
在一种实施方式中，当一个SRI域的一个取值指示两个SRI时，其中某个SRI可以不指示任何SRS资源，表示对应的SRS资源集合不被使用，此时，所有的重复传输都采用另一个SRI来确定发送波束，和/或，天线端口，从而达到在两个SRI之间动态切换的效果。由于不同的SRI对应不同的TRP接收，这样就可以支持两个TRP接收点之间的动态切换，灵活选择当前最好的TRP作为接收点，达到更好的传输性能。
可选的，本发明实施例可以用于基于码本的PUSCH传输，即前述第一SRS资源集合和第二SRS资源集合为用于上行码本传输的SRS资源集合(即SRS资源集合的usage参数配置为Codebook)。
可选的，终端设备可以采用如下方法，确定PUSCH的不同重复传输所使用的发送波束、天线端口或发送功率：
1)所述终端设备将所述PUSCH的一次重复传输对应的SRI所指示的SRS资源所使用的发送波束，作为所述一次重复传输的发送波束。
可以理解的是，所述PUSCH的每次重复传输与该重复传输对应的SRI所指示的SRS资源使用相同的发送波束。例如，PUSCH的部分重复传输对应第一SRI，则这些重复传输与第一SRI所指示的第一SRS资源使用相同的发送波束；其他重复传输对应第二SRI，则这些重复传输与第二SRI所指示的第二SRS资源使用相同的发送波束。本发明实施例中，发送波束也可以称为空间域传输滤波器或者空间滤波器。
2)所述终端设备将所述PUSCH的一次重复传输对应的SRI所指示的SRS资源的端口数，作为所述一次重复传输的端口数。
可以理解的是，所述PUSCH的每次重复传输所使用的天线端口数等于该重复传输对应的SRI所指示的SRS资源的端口数。例如，PUSCH的部分重复传输对应第一SRI，则这些重复传输所使用的天线端口数等于第一SRS资源的端口数；其他重复传输对应第二SRI，则这些重复传输所使用的天线端口数等于第二SRS资源的端口数。终端可以进一步根据天线端口数来确定所使用的码本。
3)所述一个SRI域的至少一个取值对应两组PUSCH功率控制参数，分别用于确定所述PUSCH的不同重复传输的发送功率。具体的，所述一个SRI域的至少一个取值对应两组PUSCH功率控制参数，所述终端设备根据所述PUSCH的一次重复传输对应的SRI，从所述两组PUSCH功率控制参数中，确定所述一次重复传输所用的PUSCH功率控制参数；根据所述PUSCH功率控制参数，确定所述一次重复传输的发送功率。即所述两组PUSCH功率控制参数分别用于确定所述PUSCH的不同重复传输所使用的发送功率。
下面考虑两种可能的配置情况：
i、一个SRI域的部分取值可以指示一个SRI，其他取值可以指示两个SRI。
在一种实施方式中，如果一个SRI域的某个取值指示两个SRI，则所述取值对应两组PUSCH功率控制参数，分别用于确定不同重复传输的发送功率。如果一个SRI域的某个取值指示一个SRI，则所述取值对应一组PUSCH功率控制参数，所有的重复传输都采用这组功率控制参数来确定发送功率。
在另一种实施方式中，如果一个SRI域的每个取值都对应两组PUSCH功率控制参数，则当某个取值指示两个SRI时，所述两组PUSCH功率控制参数分别用于确定不同重复传输的发送功率；当某个取值指示一个SRI时，终端采用所述两组PUSCH功率控制参数中的一组来确定所有重复传输的发送功率，例如其中的第一组功率控制参数。在一些特殊配置下，例如，当某个取值指示两个SRI但其中一个SRI不指示任何SRS资源时，终端设备采用另一个SRI对应的PUSCH功率控制参数来确定所有重复传输的发送功率。
例如，所述一个SRI域的取值范围是0-7，其中取值4-7指示两个SRI，则这些取值中每个取值都对应两组PUSCH功率控制参数，终端设备根据重复传输对应的SRI，来确定该重复传输所使用的功率控制参数。如果PUSCH的部分重复传输对应其中的第一SRI，则这些重复传输的发送功率根据第一组功率控制参数确定；如果PUSCH的部分重复传输对应其中的第二SRI，则这些重复传输的发送功率根据第二组功率控制参数确定。
ii、一个SRI域的所有取值可以都指示一个SRI，或者都指示两个SRI，采用哪种取决于高层信令的配置。如果高层信令配置一个SRI域只指示一个SRI，则所述SRI域的每个取值都对应一组PUSCH功率控制参数；如果高层信令配置一个SRI域指示两个SRI，则所述SRI域的每个取值都可以对应两组PUSCH功率控制参数。终端设备根据重复传输对应的SRI，来确定该重复传输所使用的功率控制参数为其中哪一组功率控制参数。
在一种实施方式中，一个SRI域的不同取值对应的两组PUSCH功率控制参数可以通过高层信令配置给终端设备。
可选的，所述终端设备根据所述传输参数，分别进行所述PUSCH的多次重复传输，可以包括：终端设备根据所述第三传输参数，分别进行所述PUSCH的多次重复传输。
例如，奇数次的重复传输和偶数次的重复传输使用不同的发送波束和/或天线端口；或者，前两次重复传输和后两次重复传输使用不同的发送波束和/或天线端口，以此类推。
在本发明实施例中，终端设备根据一个SRI域指示的两个SRI，得到两组发送波束和/或天线端口，用于不同的PUSCH重复传输，从而分别匹配与不同TRP之间的信道，提高上行多TRP分集传输的性能。
实现方式4：
所述终端设备根据所述两个SRI集合，分别确定PUSCH的不同重复传输所使用的第三传输参数，所 述第三传输参数包括所述发送波束、所述天线端口、所述传输层数和所述发送功率中的至少一个。
可选的，所述两个SRI集合包括第一SRI集合和第二SRI集合，所述第一SRI集合指示第三SRS资源集合中的一个或多个单端口SRS资源，所述第二SRI集合指示第四SRS资源集合中的一个或多个单端口SRS资源。即两个SRI集合中的第一SRI集合指示第三SRS资源集合中的一个或多个单端口SRS资源，第二SRI集合指示第四SRS资源集合中的一个或多个单端口SRS资源。所述第三SRS资源集合和第四SRS资源集合可以预先配置给终端设备。
在一些实施例方式中，一个SRI集合中可以不包含任何SRI，即不指示任何SRS资源，表示对应的SRS资源集合不被使用，此时，所有的重复传输都采用另一个SRI集合来确定传输参数，从而达到在两个SRI集合之间动态切换的效果。由于不同的SRI集合对应不同的TRP接收，这样就可以支持两个TRP接收点之间的动态切换，灵活选择当前最好的TRP作为接收点，达到更好的传输性能。
可选的，每个SRI集合中可以包含一个或多个SRI，且所述两个SRI集合中包含的SRI的数量是相同的。
可选的，本发明实施例可以用于基于码本的PUSCH传输，即前述第三SRS资源集合和第四SRS资源集合为用于上行非码本传输的SRS资源集合(该集合的usage参数配置为NonCodebook)。
可选的，每个SRI集合中可以包含一个或多个SRI，且两个SRI集合中包含的SRI的数量是相同的。
可选的，所述一个SRI域的至少一个取值分别对应的两个SRI集合通过高层信令通知给所述终端设备，或者，由所述终端设备与网络设备预先约定的。
可以理解的是，所述一个SRI域的不同取值对应的两个SRI集合可以通过MAC层信令通知给终端设备，或者由终端设备与网络设备(例如基站)预先约定好。例如，网络设备可以通过如下表格通知终端SRI域的每个取值对应的SRI集合，或者终端与网络设备预先约定好如下表的对应关系(其中一个大括号内为一个SRI集合)。在一些实施方式中，不同的取值可以对应不同数量的SRI集合；在另一些实施方式中，所有的取值都对应相同数量的SRI集合，且SRI集合的数量是1还是2由高层信令预先配置。

3)可选的，所述终端设备将所述PUSCH的一次重复传输对应的SRI集合，所指示的一个或多个SRS资源的天线端口，作为传输所述一次重复传输的各个传输层的天线端口。
可以理解的是，所述PUSCH的各次重复传输与该重复传输对应的SRI集合所指示的SRS资源使用相同的天线端口。例如，PUSCH的每个重复传输包含两个传输层，其中部分重复传输对应第一SRI集合，该第一SRI集合指示了两个单端口的SRS资源，则这些重复传输中的每个重复传输都与所述两个SRS资源使用相同的天线端口(即第一个传输层与第一个SRS资源使用相同的天线端口，第二个传输层与第二个SRS资源使用相同的天线端口)。对应第二SRI集合的重复传输采用相同的方法。
4)所述一个SRI域的至少一个取值对应两组PUSCH功率控制参数，所述终端设备根据所述PUSCH的一次重复传输对应的SRI集合，从所述两组PUSCH功率控制参数中，确定所述一次重复传输所用的 PUSCH功率控制参数；根据所述PUSCH功率控制参数，确定所述一次重复传输的发送功率。即所述两组PUSCH功率控制参数分别用于确定所述PUSCH的不同重复传输的发送功率。具体的，可以采用如下的实施方式：
i、在一种实施方式中，如果一个SRI域的某个取值指示两个SRI集合，则所述取值对应两组PUSCH功率控制参数，分别用于确定不同重复传输的发送功率。如果一个SRI域的某个取值指示一个SRI集合，则所述取值对应一组PUSCH功率控制参数，所有的重复传输都采用这组功率控制参数来确定发送功率。例如，所述一个SRI域的取值范围是0-7，其中取值4-7指示两个SRI集合，则这些取值中每个取值都对应两组PUSCH功率控制参数，终端设备根据重复传输对应的SRI集合，来确定该重复传输所使用的功率控制参数。如果PUSCH的部分重复传输对应其中的第一SRI集合，则这些重复传输的发送功率根据第一组功率控制参数确定；如果PUSCH的部分重复传输对应其中的第二SRI集合，则这些重复传输的发送功率根据第二组功率控制参数确定。
ii、在另一种实施方式中，如果一个SRI域的每个取值都对应两组PUSCH功率控制参数，则当某个取值指示两个SRI集合时，所述两组PUSCH功率控制参数分别用于确定不同重复传输的发送功率；当某个取值指示一个SRI集合时，终端设备采用所述两组PUSCH功率控制参数中的一组来确定所有重复传输的发送功率，例如其中的第一组功率控制参数。在一些特殊配置下，例如，当某个取值指示两个SRI集合但其中一个SRI集合不指示任何SRI时，终端设备采用另一个SRI集合对应的PUSCH功率控制参数来确定所有重复传输的发送功率。
iii、在另一种实施方式中，一个SRI域的所有取值可以都指示一个SRI集合，或者都指示两个SRI集合，采用哪种取决于高层信令的配置。如果高层信令配置SRI域只指示一个SRI集合，则所述一个SRI域的每个取值都对应一组PUSCH功率控制参数；如果高层信令配置SRI域指示两个SRI集合，则所述一个SRI域的每个取值都可以对应两组PUSCH功率控制参数。终端设备根据重复传输对应的SRI集合，来确定该重复传输所使用的功率控制参数为其中哪一组功率控制参数。
可选的，一个SRI域的不同取值对应的两组PUSCH功率控制参数可以通过高层信令配置给终端设备。
可选的，所述终端设备根据所述传输参数，分别进行所述PUSCH的多次重复传输，可以包括：终端设备根据所述第四传输参数，分别进行所述PUSCH的多次重复传输。
