Description

信道测量方法和用户设备 技术领域
本发明实施例涉及信道测量技术，尤其涉及一种信道测量方法和用户设备。
背景技术
第五代移动通信技术(5th-Generation，5G)的新空口(new radio，NR)中支持基于码本的上行传输模式。基站可以通过高层信令配置至少一个探测参考信号(Sounding Reference Signal，SRS)资源。用户设备(User equipment，UE)根据基站配置的SRS资源和指示信令在该SRS资源上发送SRS。基站接收并测量用户设备发送的SRS。当基站调度该用户进行上行数据发送时，将通过下行控制信息(DCI Downlink control information，DCI)指示SRS资源指示(SRS resource indication，SRI),传输层数(Transmission rank indication，TRI)和传输预编码矩阵(Transmission precoding matrix indication，TPMI)。UE基于该指示信息确定发送数据所使用的传输层数和预编码方式。TRI和TPMI可以联合编码，也就是说，通过指示一个DCI字段中的某个状态可以同时指示传输层数和预编码矩阵信息。传输层数可以从集合{1,2,3,4}中选择并指示，TPMI(W)基于表1-表7进行选择并指示。其中，矩阵的行对应PUSCH的传输天线端口，也可以对应SRS端口，矩阵的列对应传输层。经过调制编码之后的信息比特[y (0)(i)...y (υ-1)(i)] T，

终端设备会上报各个发送天线之间的相干能力。对于支持最大2天线端口的终端设备，相干能力包括完全相干(fully-coherent)能力和非相干(non-coherent)能力。其中，完全相干(fully-coherent)能力，表明终端设备的2个发送天线端口之间完成相位校准，可以进行相位加权，即：可以采用2个发送天线发送同一层数据；非相干(non-coherent)能力，表明终端设备的2个发送天线之间未完成相位校准，则不可以进行相位加权发送相同一层数据，即：只能使用一根天线发送同一层数据。对于最大2天线端口的终端设备，若上报非相干能力，则仅能支持表6中的TPMI 0-1和表7中的TPMI 0，可选的，还可以支持TPMI 2用于使能满功率PUSCH传输，若上报完全相干能力，可以支持表6和表7中的所有TPMI。
对于支持最大4天线端口的终端设备，相干能力包括完全相干(fully-coherent)能力、部分相干(partially-coherent)能力和非相干(non-coherent)能力。其中，对于完全相干(fully-coherent)能力，表明UE的全部发送天线完成相位校准，可以进行相位加权，即所有UE天线均可以发送同一个数据层。例如，可以支持表1-5中的所有TPMI。对于部分相干(partially-coherent)能力，表明UE的两两发送天线组内完成相位校准，可以进行相位加权，而UE的两两发送天线组间未完成相位校准，不可以进行相位加权，即天线组内的2个发送天线可以发送同一层数据。例如，可以支持表1和表2中的TPMI 0-11，表3中的TPMI 0-13，表4和表5中的TPMI 0-2，可选的，还可以支持表1和表2中的TPMI 12-15，或者进一步支持表1中的TPMI 16-19，这些TPMI用于使能满功率PUSCH传输，此时，终端设备无法保持基站所指示的天线间的相位。对于非相干(non-coherent)能力，表明UE的4个发送天线之间均未完成相位校准，均不可以进行相位加权发送相同的数据层，即对于同一层数据，只能使用一根天线发送。例如，可以支持表1和表2中的TPMI 0-3，表3中的TPMI 0-5，表4和表5中的TPMI 0，可选的，还可以支持表1和表2中的TPMI 13，表3中的TPMI 6，表4中的TPMI 1，这些TPMI用于使能满功率PUSCH传输，此时，终端设备无法保持基站所指示的天线间的相位。

具体实施方式
目前正处于研发阶段的下一代无线通信系统又可称为新无线(New Radio，NR)系统或者5G系统。最新研究进展显示，下一代无线通信标准支持半静态信道测量，并且半静态信道测量得到的CSI可以通过物理上行共享信道(Physical Uplink Shared Channel，PUSCH)进行传送。在支持半静态信道测量时，首先需要解决的一个问题便是如何通知用 户设备启动和停止半静态信道测量。本发明实施例提供了一种技术方案，有助于解决上述问题。下文就结合附图和具体实施例来对本发明实施例提供的技术方案进行描述。
本发明实施例提供一种通信设备，该通信设备可以用于实现上述接入设备，也可以用于实现上述用户设备。该通信设备包括处理器和收发器，处理器用于执行上述处理模块的操作，收发器用于执行上述收发模块所执行的操作。
在具体实现过程中，处理器可用于进行，例如但不限于，基带相关处理，收发器可用于进行，例如但不限于，射频收发。上述器件可以分别设置在彼此独立的芯片上，也可以至少部分的或者全部的设置在同一块芯片上。例如，处理器可以进一步划分为模拟基带处理器和数字基带处理器，其中模拟基带处理器可以与收发器集成在同一块芯片上，数字基带处理器可以设置在独立的芯片上。随着集成电路技术的不断发展，可以在同一块芯片上集成的器件越来越多，例如，数字基带处理器可以与多种应用处理器(例如但不限于图形处理器，多媒体处理器等)集成在同一块芯片之上。这样的芯片可以称为系统芯片(System on Chip)。将各个器件独立设置在不同的芯片上，还是整合设置在一个或者多个芯片上，往往取决于产品设计的具体需要。本发明实施例对上述器件的具体实现形式不做限定。
本发明实施例还提供一种处理器，用于执行上述各种方法。在执行这些方法的过程中，上述方法中有关发送上述信息和接收上述信息的过程，可以理解为由处理器输出上述信息的过程，以及处理器接收输入的上述信息过程。具体来说，在输出上述信息时，处理器将该上述信息输出给收发器，以便由收发器进行发射。更进一步的，该上述信息在由处理器输出之后，还可能需要进行其他的处理，然后才到达收发器。类似的，处理器接收输入的上述信息时，收发器接收该上述信息，并将其输入处理器。更进一步的，在收发器收到该上述信息之后，该上述信息可能需要进行其他的处理，然后才输入处理器。
基于上述原理，举例来说，前述方法中提及的接收传输参数指示信息可以理解为处理器接收输入的传输参数指示信息。又例如，发送传输参数指示信息可以理解为处理器输出传输参数指示信息。
如此一来，对于处理器所涉及的发射、发送和接收等操作，如果没有特殊说明，或者，如果未与其在相关描述中的实际作用或者内在逻辑相抵触，则均可以更加一般性的理解为处理器输出和接收输入等操作，而不是直接由射频电路和天线所进行的发射、发送和接收操作。
在具体实现过程中，上述处理器可以是专门用于执行这些方法的处理器，也可以是执行存储器中的计算机指令来执行这些方法的处理器，例如通用处理器。上述存储器可以为非瞬时性(non-transitory)存储器，例如只读存储器(Read Only Memory，ROM)，其可以与处理器集成在同一块芯片上，也可以分别设置在不同的芯片上，本发明实施例对存储器的类型以及存储器与处理器的设置方式不做限定。
根据本发明实施例的第二十方面，提供一种计算机可读存储介质，包括指令，当其在计算机上运行时，使得计算机执行上述各种方法。更进一步的，计算机可读存储介质为非瞬时性的计算机可读存储介质。
根据本发明实施例的第二十一方面，提供一种包含指令的计算机程序产品，当其在计算机上运行时，使得计算机执行上述各种方法。
图1是依照本发明一实施例的无线通信网络100的示范性示意图。如图1所示，无线通信网络100包括基站102～106和终端设备108～122，其中，基站102～106彼此之间可通 过回程(backhaul)链路(如基站102～106彼此之间的直线所示)进行通信，该回程链路可以是有线回程链路(例如光纤、铜缆)，也可以是无线回程链路(例如微波)。终端设备108～122可通过无线链路(如基站102～106与终端设备108～122之间的折线所示)与对应的基站102～106通信。
基站102～106通常作为接入设备来为通常作为用户设备的终端设备108～122提供无线接入服务。具体来说，每个基站都对应一个服务覆盖区域(又可称为蜂窝，如图1中各椭圆区域所示)，进入该区域的终端设备可通过无线信号与基站通信，以此来接受基站提供的无线接入服务。基站的服务覆盖区域之间可能存在交叠，处于交叠区域内的终端设备可收到来自多个基站的无线信号，因此这些基站可以进行相互协同，以此来为该终端设备提供服务。例如，多个基站可以采用多点协作(Coordinated multipoint，CoMP)技术为处于上述交叠区域的终端设备提供服务。例如，如图1所示，基站102与基站104的服务覆盖区域存在交叠，终端设备112便处于该交叠区域之内，因此终端设备112可以收到来自基站102和基站104的无线信号，基站102和基站104可以进行相互协同，来为终端设备112提供服务。又例如，如图1所示，基站102、基站104和基站106的服务覆盖区域存在一个共同的交叠区域，终端设备120便处于该交叠区域之内，因此终端设备120可以收到来自基站102、104和106的无线信号，基站102、104和106可以进行相互协同，来为终端设备120提供服务。
依赖于所使用的无线通信技术，基站又可称为节点B(NodeB)，演进节点B(evolved NodeB,eNodeB)以及接入点(Access Point，AP)等。此外，根据所提供的服务覆盖区域的大小，基站又可分为用于提供宏蜂窝(Macro cell)的宏基站、用于提供微蜂窝(Pico cell)的微基站和用于提供毫微微蜂窝(Femto cell)的毫微微基站等。随着无线通信技术的不断演进，未来的基站也可以采用其他的名称。
终端设备108～122可以是具备无线通信功能的各种无线通信设备，例如但不限于移动蜂窝电话、无绳电话、个人数字助理(Personal Digital Assistant，PDA)、智能电话、笔记本电脑、平板电脑、无线数据卡、无线调制解调器(Modulator demodulator，Modem)或者可穿戴设备如智能手表等。随着物联网(Internet of Things，IOT)技术和车联网(Vehicle-to-everything，V2X)技术的兴起，越来越多之前不具备通信功能的设备，例如但不限于，家用电器、交通工具、工具设备、服务设备和服务设施，开始通过配置无线通信单元来获得无线通信功能，从而可以接入无线通信网络，接受远程控制。此类设备因配置有无线通信单元而具备无线通信功能，因此也属于无线通信设备的范畴。此外，终端设备108～122还可以称为移动台、移动设备、移动终端、无线终端、手持设备、客户端等。
基站102～106，和终端设备108～122均可配置有多根天线，以支持MIMO(多入多出，Multiple Input Multiple Output)技术。进一步的说，基站102～106和终端设备108～122既可以支持单用户MIMO(Single-User MIMO，SU-MIMO)技术，也可以支持多用户MIMO(Multi-User MIMO，MU-MIMO)，其中MU-MIMO可以基于空分多址(Space Division Multiple Access，SDMA)技术来实现。由于配置有多根天线，基站102～106和终端设备108～122还可灵活支持单入单出(Single Input Single Output，SISO)技术、单入多出(Single Input Multiple Output，SIMO)和多入单出(Multiple Input Single Output，MISO)技术，以实现各种分集(例如但不限于发射分集和接收分集)和复用技术，其中分集技术可以包括例如但不限于发射分集(Transmit Diversity，TD)技术和接收分集(Receive Diversity， RD)技术，复用技术可以是空间复用(Spatial Multiplexing)技术。而且上述各种技术还可以包括多种实现方案，例如发射分集技术可以包括，例如但不限于，空时发射分集(Space-Time Transmit Diversity，STTD)、空频发射分集(Space-Frequency Transmit Diversity，SFTD)、时间切换发射分集(Time Switched Transmit Diversity，TSTD)、频率切换发射分集(Frequency Switch Transmit Diversity，FSTD)、正交发射分集(Orthogonal Transmit Diversity，OTD)、循环延迟分集(Cyclic Delay Diversity，CDD)等分集方式，以及上述各种分集方式经过衍生、演进以及组合后获得的分集方式。例如，目前LTE(长期演进，Long Term Evolution)标准便采用了空时块编码(Space Time Block Coding，STBC)、空频块编码(Space Frequency Block Coding，SFBC)和CDD等发射分集方式。上文以举例的方式对发射分集进行了的概括性的描述。本领域技术人员应当明白，除上述实例外，发射分集还包括其他多种实现方式。因此，上述介绍不应理解为对本发明技术方案的限制，本发明技术方案应理解为适用于各种可能的发射分集方案。
此外，基站102～106和终端设备108～122可采用各种无线通信技术进行通信，例如但不限于，时分多址(Time Division Multiple Access，TDMA)技术、频分多址(Frequency Division Multiple Access，FDMA)技术、码分多址(Code Division Multiple Access，CDMA)技术、时分同步码分多址(Time Division-Synchronous Code Division Multiple Access，TD-SCDMA)、正交频分多址(Orthogonal FDMA，OFDMA)技术、单载波频分多址(Single Carrier FDMA，SC-FDMA)技术、空分多址(Space Division Multiple Access，SDMA)技术以及这些技术的演进及衍生技术等。上述无线通信技术作为无线接入技术(Radio Access Technology，RAT)被众多无线通信标准所采纳，从而构建出了在今天广为人们所熟知的各种无线通信系统(或者网络)，包括但不限于全球移动通信系统(Global System for Mobile Communications，GSM)、CDMA2000、宽带CDMA(Wideband CDMA，WCDMA)、由802.22系列标准中定义的WiFi、全球互通微波存取(Worldwide Interoperability for Microwave Access，WiMAX)、长期演进(Long Term Evolution，LTE)、LTE升级版(LTE-Advanced，LTE-A)以及这些无线通信系统的演进系统等。如无特别说明，本发明实施例提供的技术方案可应用于上述各种无线通信技术和无线通信系统。此外，术语“系统”和“网络”可以相互替换。
应注意，图1所示的无线通信网络100仅用于举例，并非用于限制本发明的技术方案。本领域的技术人员应当明白，在具体实现过程中，无线通信网络100还可能包括其他设备，同时也可根据具体需要来配置基站和终端设备的数量。

可选的，在接收传输参数指示信息之前，接收码本子集配置信息，码本子集配置信息用于指示第一码本子集配置和第二码本子集配置中的至少一个。可选的，根据码本子集配置信息，接收传输参数指示信息。具体的，根据码本子集配置信息，确定传输参数指示信息的比特位数，以及该指示信息的每个状态位对应的含义。每个状态位对应的含义包括，传输层数和相应的TPMI。TRI和TPMI联合编码的字段中的状态用于指示数据传输所使用的TRI和TPMI。每个TRI取值都会对应一组预编码矩阵，对应关系如表1-4所示。当某一个传输层数被指示时,TPMI用于指示从该传输层数对应的一组预编码矩阵中选择其中一个预编码矩阵。表8是一种TRI和TPMI联合编码的示例。其中，所指示的传输层数，也就是TRI是通过表中的层x指示的，其中x的取值范围是{1,2,3,4}。所指示的预编码矩阵是通过表中的TPMI＝y指示的，其中y是大于等于1的正整数，y的取值范围根据表1-4中每个传输层数对应的三种UE能力对应的预编码矩阵个数确定。在本实施例中，对于每种UE能力，TRI和TPMI联合编码字段的索引按照层数从小到大而从小到大排列。如表8中所示，对于完全相干传输能力，该字段的索引0-27表示层1传输，其中每个索引都对应了层1传输对应的一个预编码矩阵索引，包括完全相干对应的码字，部分相干对应的码字和非相干对应的码字；该字段的索引28-49表示层2传输，其中每个索引都对应了层2传输对应的一个预编码矩阵索引，包括完全相干对应的码字，部分相干对应的码字和非相干对应的码字；该字段的索引50-56表示层3传输，其中每个索引都对应了层3传输对应的一个预编码矩阵索引，包括完全相干对应的码字，部分相干对应的码字和非相干对应的码字；该字段的索引57-61表示层4传输，其中每个索引都对应了层4传输对应的一个预编码矩阵索引，包括完全相干对应的码字，部分相干对应的码字和非相干对应的码字。
具体的，对于4T的情况，即终端设备可以支持的最大天线端口数量为4的情况，针对第一码本子集配置，在最大rank数为1的情况下，第一码本子集配置中包括表1和表2中的TPMI 0-3，或者，第一码本子集配置中包括表1和表2中的TPMI 0-3，以及TPMI 13，或者，第一码本子集配置中包括表1和表2中的TPMI 0-3，以及TPMI 4、8，以及TPMI 13。在最大rank数为2的情况下，第一码本子集配置中除了可以包括最大rank数为1的情况下的码字，还可以包括表3中的TPMI 0-5；或者，第一码本子集配置中包括表3中的TPMI 0-6。在最大rank数为3的情况下，第一码本子集配置中除了可以包括最大rank数为2的情况下的码字，还可以包括表4中的TPMI 0-1。在最大rank数为4的情况下，第一码本子集配置中除了可以包括最大rank数为3的情况下的码字，还可以包括表5中的 TPMI 0。应理解，当可以支持的最大天线端口数大于4的时候，在采用4端口配置的时候，也适用上述实施例。
针对第二码本子集配置，在最大rank数为1的情况下，第一码本子集配置中包括表1和表2中的TPMI 0-11，或者，第一码本子集配置中包括表1和表2中的TPMI 0-11，以及TPMI 12-15，或者，第一码本子集配置中包括表1和表2中的TPMI 0-11，以及TPMI 12-19。在最大rank数为2的情况下，第一码本子集配置中除了可以包括最大rank数为1的情况下的码字，还可以包括表3中的TPMI 0-13。在最大rank数为3的情况下，第一码本子集配置中除了可以包括最大rank数为2的情况下的码字，还可以包括表4中的TPMI 0-2。在最大rank数为4的情况下，第一码本子集配置中除了可以包括最大rank数为3的情况下的码字，还可以包括表5中的TPMI 0-2。
本发明中，传输层数指示(TRI)和预编码矩阵指示(TPMI)联合编码。也就是说，字段中每一个状态位均对应一个传输层数指示以及相应传输层数下的预编码矩阵指示。每个TRI取值都会对应一组预编码矩阵，对应关系如表1-7所示。当某一个传输层数被指示时,TPMI用于指示从该传输层数对应的一组预编码矩阵中选择其中一个预编码矩阵。表8和表9是一种TRI和TPMI联合编码的示例。其中，所指示的传输层数，也就是TRI是通过表中的x层指示的，其中x的取值范围限制为1，也就是当前PUSCH传输的最大传输层数被配置为1。所指示的预编码矩阵是通过表中的TPMI＝y指示的，其中y是大于等于1的正整数，y的取值范围根据表1-7中特定传输层数下的预编码矩阵个数确定，对于表8和表9，y的取值范围根据表1和表2的预编码矩阵个数确定。同时，特定y下的预编码矩阵还会根据最大发送天线端口数确定，表8和表9中，最大发送天线端口数量为4。进一步的，特定y下的预编码矩阵还会根据传输波形确定，例如，以TPMI＝12为例，当传输波形为DFT-s-OFDM，则TPMI＝12对应的预编码矩阵为

(对应表1)，当传输波形为CP-OFDM，则TPMI＝12对应的预编码矩阵为
Figure PCTCN2020124884-appb-000032
(对应表2)。进一步的，TRI和TPMI联合编码指示的比特数大小以及每个状态值对应的传输层数和预编码矩阵指示需要根据码本子集配置确定。例如，当码本子集配置为第一码本子集，则该字段的比特数为3比特，当码本子集配置为第二码本子集，则该字段的比特数为4比特。
当第一码本子集对应的5个第一索引值中的任意一个第一索引值m与第二码本子集对应的16个第二索引值中的任意一个第二索引值n相同时，第一索引值m对应的传输层数的值和预编码矩阵指示与所述第二索引值n对应的传输层数的值和预编码矩阵指示相同，且所述第一索引值m对应的预编码矩阵指示关联的预编码矩阵和所述第二索引值n对应的预编码矩阵指示关联的预编码矩阵相同。其中，对于第一码本子集配置而言，字段的索引值5-7为保留的，表明，该索引值对应的内容为空集。
可选的，表8、表9用于CP-OFDM波形和DFT-s-OFDM波形。
可选的，表8、表9用于CP-OFDM波形，表10、表11用于DFT-s-OFDM波形。

当第一码本子集对应的12个第一索引值中的任意一个第一索引值m与第二码本子集对应的30个第二索引值中的任意一个第二索引值n相同时，第一索引值m对应的传输层数的值和预编码矩阵指示与所述第二索引值n对应的传输层数的值和预编码矩阵指示相同，且所述第一索引值m对应的预编码矩阵指示关联的预编码矩阵和所述第二索引值n对应的预编码矩阵指示关联的预编码矩阵相同。

当第一码本子集对应的15个第一索引值中的任意一个第一索引值m与第二码本子集对应的36个第二索引值中的任意一个第二索引值n相同时，第一索引值m对应的传输层数的值和预编码矩阵指示与所述第二索引值n对应的传输层数的值和预编码矩阵指示相同，且所述第一索引值m对应的预编码矩阵指示关联的预编码矩阵和所述第二索引值n对应的预编码矩阵指示关联的预编码矩阵相同。

当第一码本子集对应的17个第一索引值中的任意一个第一索引值m与第二码本子集对应的38个第二索引值中的任意一个第二索引值n相同时，第一索引值m对应的传输层数的值和预编码矩阵指示与所述第二索引值n对应的传输层数的值和预编码矩阵指示相同，且所述第一索引值m对应的预编码矩阵指示关联的预编码矩阵和所述第二索引值n 对应的预编码矩阵指示关联的预编码矩阵相同。

方法300中涉及的技术细节已经在上文结合方法200进行了详细的描述，因此此处不再赘述。
图3是本发明的又一种实施方式。在具体实现过程中，步骤402可由网络设备执行，步骤404可由终端设备执行。
步骤402，根据SRS资源的配置信息，发送第二传输参数控制信息。具体包括，根据配置的多个SRS资源中端口数最大的SRS资源的端口数，确定第二传输参数控制信息中第一传输指示字段的比特数，第一传输指示字段用于指示PUSCH传输采用的传输层数以及相应的预编码矩阵；根据第二传输参数控制信息所指示的SRS资源的端口数，确定在第二传输参数控制信息中填零的比特位数。
例如，第二传输参数控制信息为调度PUSCH的DCI，第一传输指示字段用于指示PUSCH的传输层数和相应的TPMI。多个SRS资源中端口数最大的SRS资源的端口数用于确定第一传输指示字段的比特数(N1)。第二传输参数控制信息中还包括SRS资源指示(SRS resource indication，SRI)字段，该字段用于指示从配置的多个SRS资源中选择一个。SRI字段所指示的SRS资源的端口数用于确定有效的比特位数(N2)以及填零的比特位数，有效的比特位数为用于指示TPMI和传输层数的比特位数，填零的比特位数为N1-N2。
比如，配置了两个SRS资源的端口数分别为2和4，则SRS端口数为4用于确定第一传输指示字段的比特数，即，第一传输指示字段中指示的TPMI行数为4，SRI用于指示选择端口数为2的SRS资源还是端口数为4的SRS资源。当SRI指示了4端口的SRS资源，则第一传输指示字段的比特数N1和有效的比特位数N2相同，没有填零的比特位数；当SRI指示了2端口的SRS资源，则由于4天线码本和2天线码本对应的比特数不同导致第一传输指示字段的比特数N1和有效的比特位数N2不相同，存在填零的比特位数N1-N2。
可选的，填零的N位比特位于第二传输参数控制信息中末尾N位比特。比如，第二传输参数控制信息的总比特位数为X1，前X1-N位比特为指示有效信息的比特位，最后N位比特为填零比特位。
可选的，填零的N位比特位于第二传输参数控制信息中第一传输指示字段有效比特位之后的N位比特。比如，第二传输参数控制信息的总比特位数为X1，前X1-K位比特为指示有效信息的比特位，K>N，K位比特中的N位比特为相应的填零比特位。
可选的，填零的N位比特位于第一传输参数控制信息中有效比特位之后的N位比特位。比如，第一传输参数控制信息位于第二传输参数控制信息中第k 0-k i个比特位，其中，根据SRI指示的SRS资源端口数确定的有效比特位数为N2，则第k 0-k N2-1个比特位为有效比特位，第k N2-k i个比特位为填零的比特位。
步骤404，根据SRS资源的配置信息，接收第二传输参数控制信息。具体包括，根据配置的多个SRS资源中端口数最大的SRS资源的端口数，确定第二传输参数控制信息中第一传输指示字段的比特数，第一传输指示字段用于指示PUSCH传输采用的传输层数以及相应的预编码矩阵；根据第二传输参数控制信息所指示的SRS资源的端口数，确定在第二传输参数控制信息中填零的比特位数。

可选的，填零的N位比特位于第二传输参数控制信息中末尾N位比特。比如，第二传输参数控制信息的总比特位数为X1，前X1-N位比特为指示有效信息的比特位，最后N位比特为填零比特位。

可选的，填零的N位比特位于第一传输参数控制信息中有效比特位之后的N位比特位。比如，第一传输参数控制信息位于第二传输参数控制信息中第k 0-k i个比特位，其中，根据SRI指示的SRS资源端口数确定的有效比特位数为N2，则第k 0-k N2-1个比特位为有效比特位，第k N2-k i个比特位为填零的比特位。图4是依照本发明一实施例的通信设备900的示范性逻辑结构示意图。在具体实现过程中，通信设备900可以是上文所述的接入设备，也可以上文所述的用户设备。如图4所示，通信设备900包括收发模块902和处理模块904。
