  • Codebook-based uplink transmission may also be referred to as codebook transmission.
  • Codebook-based uplink transmission is a multi-antenna transmission technology that determines the TPMI of uplink transmission based on a fixed codebook.
  • the process of codebook-based uplink transmission in the NR system is as follows:
  • the UE sends the SRS to the base station on the SRS resource set obtained through the channel state information (Channel State Information, CSI) used for codebook-based uplink transmission.
  • CSI Channel State Information
  • the base station performs uplink channel detection according to the SRS sent by the UE, performs resource scheduling on the UE, and determines the SRS resource corresponding to the uplink transmission based on the codebook, the number of layers of the uplink transmission and the precoding matrix. Further, the UE can determine the modulation and coding strategy (Modulation and Coding Scheme, MCS) for uplink transmission according to the precoding matrix and channel information, and then the base station allocates PUSCH resources and assigns the corresponding MCS, TPMI, layer indicator (Layer Indicator, LI). ) and an SRS resource indication (Sounding Reference Signal Resource Indicator, SRI) are notified to the UE.

  • a maximum of two SRS resources can be configured in the SRS resource set, and the two SRS resources include The same number of SRS antenna ports. Since the MTRP-based PUSCH enhancement was introduced in R17, starting from R17, the NR system allows the base station to configure at most two SRS resource sets for the UE for CSI acquisition based on codebook-based uplink transmission. Whether the number of resources that can be included in the two SRS resource sets is the same is limited.
  • the base station indicates the SRS resource corresponding to the PUSCH to the UE through the SRI field in the DCI to assist the UE to determine the antenna and analog beamforming used for PUSCH transmission according to the SRS resource selected by the base station. Since the number of SRS resources configured by the base station for different uplink transmissions may be different, determining the number of bits corresponding to the SRI based on the uplink transmission can reduce the overhead of the SRI. Therefore, the size of the SRI information used to indicate the SRS resource corresponding to the PUSCH in the uplink scheduling information depends on the number of SRS resources configured for the uplink transmission corresponding to the PUSCH. When the base station configures only one SRS resource for one uplink transmission of the UE, the PUSCH under the uplink transmission corresponds to the SRS resource, and the SRI information field may not exist in the uplink scheduling information.
  • the base station can configure a SRS resource set with a purpose of "codebook" for the terminal, which includes at most two SRS resources, and all SRS resources have the same number of antenna ports.
  • the codebook subset that the base station can configure for the terminal depends on the coherent transmission capability of the terminal.
  • the R15 protocol stipulates that the coherent transmission capability is a non-coherent terminal (NC-UE) and a partially coherent terminal (PC-UE) only allowed to configure and use a part of the codebook subset. Combined with the power control rules of PUSCH, these terminals cannot reach full power when performing low-rank transmission. In an actual system, the signal-to-noise ratio of the terminal located at the edge of the cell is usually relatively low.
  • the base station In order to ensure the signal quality, the base station often schedules the terminal to perform low-rank transmission and transmit with the largest possible transmit power. The inability to transmit at full power will affect the performance of the terminal in the low signal-to-noise ratio area, thereby affecting the cell coverage.
  • NC-UE and PC-UE to achieve full power transmission at low rank is due to codebook subset limitation and PUSCH power control rules.
  • the full power transmission of PUSCH can be achieved by enhancing the codebook subset restriction or enhancing the PUSCH power control rule.
  • R16 allows the base station to configure a specific full power transmission mode for the terminal, called Mode 0 (Mode0) full power transmission mode.
  • Mode 0 full power transmission is no longer applicable if one or more of the terminal's PAs cannot transmit at full power.
  • R16 introduces two full power transmission modes, Mode 1 (Mode1) and Mode 2 (Mode2).
  • Mode 2 adopts the same codebook subset configuration restriction as R15.

本申请实施例提供了一种无线通信方法，可用于确定发送SRS的时隙。
为便于对本申请实施例的理解，下面对SRS进行介绍。
探测参考信号(Sounding Reference Signal，SRS)信号是5G/NR系统中重要的参考信号，广泛用于NR系统中的各种功能中，例如，SRS可以用于以下场景：
1.用于下行信道状态信息的获取(UE sounding procedure for DL CSI acquisition)
2.用于上行传输的频域调度和预编码确定；
3.用于天线切换(Antenna Switching)功能；
4.用于载波切换(Carrier Switching)功能(UE sounding procedure between component carriers)；
5.用于定位功能；
6.配合基于码本(codebook-based)的上行传输；
7.配合基于非码本(Non-Codebook based)的上行传输。
网络设备可以给一个终端设备配置一个或多个SRS资源集(SRS Resource set)，每个SRS Resource set可以配置1个或多个SRS resource(SRS资源)。
SRS的传输可以分为周期性(Periodic)、半持续(Semi-persistent)、非周期(Aperiodic)。
周期SRS是指周期性传输的SRS，其周期和时隙偏移由RRC信令配置，终端设备一旦接收到相应的配置参数，就按照一定的周期发送SRS，直到所述RRC配置失效。周期性SRS的空间相关信息(Spatial Relation Info)也由RRC信令配置。所述空间相关信息可以指示一个信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)，同步信号/物理广播信道块(Synchronization  Signal/PBCH Block，SSB)或者参考SRS。例如，可以通过隐式的方式来指示周期SRS的发送波束。例如，终端设备根据指示的CSI-RS/SSB来确定周期SRS的发送波束。再如，终端设备可以通过SRS资源的空间相关信息确定在SRS资源上传输SRS所用的发送波束。
半持续性SRS的周期和时隙偏移(slot offset)由RRC信令配置，但其激活和去激活信令是通过MAC CE承载的。终端设备在接收到激活信令后开始传输SRS，直到接收到去激活信令为止。半持续SRS的空间相关信息(发送波束)通过激活SRS的MAC CE一起承载。
NE系统中，以SRS资源集的方式进行SRS的管理和配置。根据不同的用途，基站可以为UE配置多个SRS资源集，每个SRS资源集包括一个或多个SRS资源，每个SRS资源包含1、2或4个端口。每个SRS资源集的配置信息中包含一个用途指示，可以被配置为波束管理(beamManagement)、码本(codebook)、非码本(nonCodebook)或天线切换(antennaSwitching)，其分别用于上行波束管理、基于码本的上行信道信息获取，非码本上行传输方案的上行信道信息获取以及基于SRS天线切换的下行信道信息获取。
为便于理解本申请的方案，下面对基于码本的上行传输的相关内容进行说明。基于码本的上行传输也可称为码本传输。基于码本的上行传输是基于固定码本确定上行传输的TPMI的多天线传输技术。NR系统中基于码本的上行传输的流程如下：
1、UE在通过用于基于码本的上行传输的信道状态信息(Channel State Information，CSI)获取的SRS资源集，上向基站发送SRS。
2、基站根据UE发送的SRS进行上行信道检测，对UE进行资源调度，并确定出基于码本的上行传输对应的SRS资源、上行传输的层数和预编码矩阵。进一步，UE可以根据预编码矩阵和信道信息，确定出上行传输的调制与编码策略(Modulation and Coding Scheme，MCS)，然后基站分配PUSCH资源并将相应的MCS、TPMI、层指示(Layer Indicator,LI)以及SRS资源指示(Sounding Reference Signal Resource Indicator，SRI)通知给UE。
3、UE根据基站指示的MCS对数据进行调制编码，并利用SRI、TPMI和LI确定数据发送时使用的预编码矩阵和传输层数，进而对数据进行预编码及发送，PUSCH的解调导频信号与PUSCH的数据采用相同的预编码方式。
4、基站根据解调导频信道估计上行信道，并进行数据检测。
在R16及以前，NR系统允许基站为UE最多配置一个通过用于基于码本的上行传输的CSI获取的SRS资源集，该SRS资源集内最多可配置两个SRS资源，这两个SRS资源包含相同的SRS天线端口数。由于在R17中引入了基于MTRP对PUSCH的增强，因此从R17开始，NR系统允许基站为UE最多配置两个用于基于码本的上行传输的CSI获取的SRS资源集，R17中并没有对这两个SRS资源集中可以包含的资源数目是否相同进行限制。基站通过DCI中的SRI域(field)向UE指示PUSCH对应的SRS资源，以辅助UE根据基站选择的SRS资源确定PUSCH传输所用的天线和模拟波束赋形等。由于基站为不同的上行传输配置的SRS资源的数目可能不同，基于上行传输确定SRI对应的比特数可以降低SRI的开销。因此，上行调度信息中用于指示PUSCH所对应的SRS资源的SRI信息的大小取决于为PUSCH对应的上行传输所配置的SRS资源数。当基站为UE的一个上行传输只配置了一个SRS资源时，该上行传输下的PUSCH对应于该SRS资源，上行调度信息中可以不存在SRI信息域。
在R15中，对于基于码本的上行传输，基站可以为终端配置一个用途为“码本”的SRS资源集，最多包含两个SRS资源，所有SRS资源的天线端口数相同。基站可以为终端配置的码本子集取决于终端的相干传输能力。R15协议规定相干传输能力为非相干的终端(NC-UE)和部分相干的终端(PC-UE)只允许配置使用一部分码本子集。结合PUSCH的功率控制规则，这些终端在进行低秩(rank)传输时不能达到满功率。在实际系统中，位于小区边缘的终端信噪比通常比较低，为了保证信号质量，基站往往会调度终端进行低秩传输，且以尽可能大的发送功率发送。无法满功率传输将影响低信噪比区域终端的性能，进而影响小区覆盖。
NC-UE和PC-UE在低秩时无法实现满功率传输是由于码本子集限制和PUSCH的功率控制规则。对码本子集限制进行增强或对PUSCH功率控制规则进行增强都可以实现PUSCH的满功率传输。对于每个功率放大器(power amplifier，PA)都可以满功率传输的终端，R16允许基站为终端配置一种特定的满功率传输模式，称之为模式0(Mode0)满功率传输模式。如果终端的一个或多个PA不能满功率传输，模式0满功率传输不再适用。为了使得全部或部分PA不能满功率传输的终端也可以实现满功率传输，R16引入了模式1(Mode1)和模式2(Mode2)这两种满功率传输模式。
模式2采用了与R15相同的码本子集配置的限制，通过新的SRS资源配置方式和新的PUSCH功率控制规则，允许非相干或部分相干的终端通过天线虚拟化或者满功率传输的PA使用特定预编码矩 阵达到PUSCH的满功率传输。模式2允许终端上报可以满功率传输的预编码矩阵，终端使用这些预编码矩阵可以进行PUSCH的满功率传输。
对于模式2方案，SRS资源集中可以最多配置4个SRS资源，当配置多个SRS资源时，多个SRS资源的天线端口数量可以相同或者不同，且最多可以配置两个不同的空间波束。
下面结合表1和表2对下行控制信道中关于TPMI的确定方案进行说明。
表1：4端口的TPMI TRI表格
Figure PCTCN2021119437-appb-000001
如表1所示，针对4端口的SRS资源，基于网络设备指示的索引，按照相应的码本子集可确定出相应的层数和TPMI。
表2：2端口的TPMI TRI表格
Figure PCTCN2021119437-appb-000002
如表2所示，针对2端口的SRS资源，基于网络设备指示的索引，按照相应的码本子集可确定 出相应的层数和TPMI。
基于以上分析可见，截止R16为止，NR系统仅允许基站为UE最多配置一个SRS资源集，这个SRS资源集内最多可配置两个SRS资源，且这两个SRS资源包含相同的SRS天线端口数。版本17(R17)中，引入了基于多TRP进行PUSCH的重复传输的方案，具体地，可通过DCI指示终端设备进行PUSCH的重复发送，进而通过不同的TRP来对PUSCH的可靠性进行增强。换言之，允许基站为UE最多配置多个SRS资源集，每一个SRS资源集内最多可配置多个SRS资源，由此，UE可基于多个SRS资源集中的SRS资源进行上行重复传输。但是，当所述多个SRS资源集中的最大端口数不同时，用于上行传输的所述多个SRS资源集中的SRS资源的端口数有可能不一样，由此，用于上行传输的所述多个SRS资源集中的SRS资源的端口数有可能存在UE不支持的端口数，使得终端设备选择的层数得不到终端设备的支持，保证不了通信质量。
基于此，本申请实施例提供了一种无线通信方法、终端设备和网络设备，能够使得终端设备实现PUSCH的重复发送，此外，在进行多TRP的上行重复传输时，能够使得终端设备选择的层数得到终端设备的支持，保证了通信质量。
图2示出了根据本申请实施例的无线通信方法200的示意性流程图，所述方法200可以由终端设备和网络设备交互执行。图2中所示的终端设备可以是如图1所示的终端设备，图2中所示的网络设备可以是如图1所示的接入网设备。
如图2所示，所述方法200可包括以下部分或全部内容：

换言之，终端设备接收用于指示PUSCH传输的指示信息，相应的，网络设备发送用于指示PUSCH传输的指示信息。

下面结合具体实施例对本申请的方案进行说明。
实施例1：
本实施例中，所述PUSCH未被配置为满功率模式2。
Case1：
如果所述PUSCH未被配置为满功率模式2，两个SRS资源集的SRS端口数都相同。
Case2：
如果所述PUSCH未被配置为满功率模式2，SRS资源集1的SRS端口数为4，SRS资源集2的SRS端口数为2，分两种情况来处理：
A、此时最大可以支持的层数为2，即DCI在指示SRS资源1的TPMI和TRI时需要按照最大层数为2，端口数为4的TPMI TRI表格来获取TPMI和TRI的指示。
B、终端认为这样的配置存在错误。
实施例2：
本实施例中，所述PUSCH被配置为满功率模式2。所述PUSCH被配置为满功率模式2的时候，一个SRS资源集中可以支持不同端口数的SRS资源。
情况1：
如果所述PUSCH被配置为满功率模式2，SRS资源集1中配置的SRS资源的端口数集合和SRS资源集2配置的SRS资源的端口数集合不同，比如SRS资源集1中配置的SRS资源的端口数集合为{2,1}，SRS资源集2中配置的SRS资源的端口数为{2,4}。分以下几种情况来处理：
A、终端认为这样的配置存在错误，不做处理。
B、终端获取SRS资源集1的最大端口数为2，同时终端获取SRS资源集2的最大端口数为4，因此终端在基于两个SRS资源集进行多波束传输时，可以支持的最大层数为2。网络侧在指示资源集1基于2端口的SRS资源进行PUSCH传输时，此时按照2端口的TPMI TRI表格(例如表2)来填写TPMI值。指示资源集2如果基于4端口的SRS资源进行PUSCH传输时，按照4端口的TPMI TRI表格(例如表1)填写TPMI值，但是支持的层数不能超过可以支持的最大层数2。
情况2：
如果所述PUSCH被配置为满功率模式2，SRS资源集1中配置的SRS资源的端口数集合和SRS资源集2配置的SRS资源的端口数集合不同，比如SRS资源集1中配置的SRS资源的端口数集合为{2}，SRS资源集2中配置的SRS资源的端口数为{2，4}。分以下几种情况来处理：
A、终端认为这样的配置存在错误，不做处理。
B、终端获取SRS资源集1的最大端口数为2，同时终端获取SRS资源集2的最大端口数为4，因此终端在基于两个SRS资源集进行多波束传输时，可以支持的最大层数为2。网络侧在指示资源集1基于2端口的SRS资源进行PUSCH传输时，此时按照2端口的TPMI TRI表格(例如表2)来填写TPMI值。指示资源集2如果基于4端口的SRS资源进行PUSCH传输时，按照4端口的TPMI TRI表格(例如表1)填写TPMI值，但是支持的层数不能超过可以支持的最大层数2。
情况3：
如果所述PUSCH被配置为满功率模式2，SRS资源集1中配置的SRS资源的端口数集合和SRS 资源集2配置的SRS资源的端口数集合不同，比如SRS资源集1中配置的SRS资源的端口数集合为{2}，SRS资源集2中配置的SRS资源的端口数为{2，4}。分以下几种情况来处理：
A、终端认为这样的配置存在错误，不做处理。
B、终端获取SRS资源集1的最大端口数为2，同时终端获取SRS资源集2的最大端口数为4，因此终端在基于两个SRS资源集进行多波束传输时，可以支持的最大层数为2。网络侧在指示资源集1基于2端口的SRS资源进行PUSCH传输时，此时按照2端口的TPMI TRI表格(例如表2)来填写TPMI值。指示资源集2如果基于2端口的SRS资源进行PUSCH传输时，按照2端口的SRS表格填写TPMI值，由于2端口和4端口的TPMI TRI表格(例如表1)所占的bit域大小不同，按照4端口的在前面做补0操作，但是支持的层数不能超过可以支持的最大层数2。
情况4：
如果所述PUSCH被配置为满功率模式2，SRS资源集1中配置的SRS资源的端口数集合和SRS资源集2配置的SRS资源的端口数集合相同，比如SRS资源集1中配置的SRS资源的端口数集合为{2,4}，SRS资源集2中配置的SRS资源的端口数为{2,4}。分以下几种情况来处理：
A、终端获取SRS资源集1的最大端口数为4，同时终端获取SRS资源集2的最大端口数为4，因此终端在基于两个SRS资源集进行多波束传输时，可以支持的最大层数为4。网络侧在指示资源集1基于2端口的SRS资源进行PUSCH传输时，此时按照2端口的TPMI TRI表格(例如表2)来填写TPMI值。指示资源集2如果基于4端口的SRS资源进行PUSCH传输时，按照4端口的TPMI TRI表格(例如表1)填写TPMI值，但是支持的层数不能超过DCI中所指示的两个SRS资源集所对应的SRS资源的端口数。
B、终端获取SRS资源集1的最大端口数为4，同时终端获取SRS资源集2的最大端口数为4，因此终端在基于两个SRS资源集进行多波束传输时，可以支持的最大层数为4。网络侧在指示资源集1和资源集2都基于4端口的SRS资源进行PUSCH传输时，此时按照4端口的SRS表格来填写两个资源集分别对应的TPMI值。
