Description

无线通信的方法、终端设备和网络设备 技术领域
本申请实施例涉及通信领域，具体涉及一种无线通信的方法、终端设备和网络设备。
背景技术
在一些场景中，引入了物理上行控制信道(Physical Uplink Control Channel，PUCCH)小区组(PUCCH Cell Groups，PUCCH CG)的概念。例如可以将所有被聚合的小区分为多个PUCCH CG，其中，包括特殊小区(SPCell)的PUCCH CG称为主PUCCH小区组(Primary PUCCH group)，其他PUCCH CG称为辅PUCCH小区组(Secondary PUCCH group)，PUCCH CG中携带PUCCH的辅小区(SCe11)称为PUCCH辅小区(PUCCH SCe11)。
在新无线(New Radio，NR)***中，当在时隙n接收到一个SCell的激活命令时，那么终端设备最早在时间点时隙n+k可以向网络设备上报信道状态信息(Channel State Information，CSI)报告。但是终端设备能够上报CSI报告的前提是该SCell所属的PUCCH group中的服务小区中至少有一个是激活的。当该SCell属于Secondary PUCCH group时，终端设备只有当该Secondary PUCCH group中的SCell激活之后才能够发送CSI报告，影响网络性能。
发明内容
本申请提供了一种无线通信的方法、终端设备和网络设备，通过为未激活的辅小区触发BFR以上报需要通过CSI报告上报的参考信号的信息，能够保证网络设备及时获知终端设备所选择的参考信号的信息，提升网络性能。
第一方面，提供了一种无线通信的方法，包括：在终端设备接收到第一信令的情况下，为第一辅小区触发波束失败恢复BFR，所述第一信令用于激活所述第一辅小区，所述第一辅小区为物理上行控制信道PUCCH辅小区。
第二方面，提供了一种无线通信的方法，包括：网络设备向终端设备发送第一信令，所述第一信令用于激活第一辅小区，所述第一辅小区为物理上行控制信道PUCCH小区；
在所述第一辅小区未激活的情况下，所述网络设备接收所述终端设备发送的波束失败恢复媒体接入控制控制元素BFR MAC CE。
第三方面，提供了一种终端设备，用于执行上述第一方面或其各实现方式中的方法。
具体地，该终端设备包括用于执行上述第一方面或其各实现方式中的方法的功能模块。
第四方面，提供了一种网络设备，用于执行上述第二方面或其各实现方式中的方法。
具体地，该网络设备包括用于执行上述第二方面或其各实现方式中的方法的功能模块。
第五方面，提供了一种终端设备，包括处理器和存储器。该存储器用于存储计算机程序，该处理器用于调用并运行该存储器中存储的计算机程序，执行上述第一方面或其各实现方式中的方法。
第六方面，提供了一种网络设备，包括处理器和存储器。该存储器用于存储计算机程序，该处理器用于调用并运行该存储器中存储的计算机程序，执行上述第二方面或其各实现方式中的方法。
第七方面，提供了一种芯片，用于实现上述第一方面至第二方面中的任一方面或其各实现方式中的方法。
具体地，该芯片包括：处理器，用于从存储器中调用并运行计算机程序，使得安装有该装置的设备执行如上述第一方面至第二方面中的任一方面或其各实现方式中的方 法。
第八方面，提供了一种计算机可读存储介质，用于存储计算机程序，该计算机程序使得计算机执行上述第一方面至第二方面中的任一方面或其各实现方式中的方法。
第九方面，提供了一种计算机程序产品，包括计算机程序指令，所述计算机程序指令使得计算机执行上述第一方面至第二方面中的任一方面或其各实现方式中的方法。
第十方面，提供了一种计算机程序，当其在计算机上运行时，使得计算机执行上述第一方面至第二方面中的任一方面或其各实现方式中的方法。
通过上述技术方案，终端设备可以在接收到辅小区的激活信令，此情况下，该辅小区通常还未激活，通过为该辅小区触发BFR，以向网络设备上报需要通过CSI报告上报的参考信号的信息，而不需要等待该辅小区激活之后再上报该参考信号的信息，从而能够保证网络设备及时获知终端设备所选择的参考信号的信息，提升网络性能。

为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
为便于更好的理解本申请实施例，对本申请相关的多波束(Multi-beam)***进行说明。
NR***的设计目标包括高频段(例如6GHz以上的频段)的大带宽通信。当工作频率变高时，传输过程中的路径损耗会增大，从而影响高频***的覆盖能力。为了能够有效地保证高频段NR***的覆盖，一种有效的技术方案便是基于大规模天线阵列(Massive MIMO)，以形成增益更大的赋形波束，克服传播损耗，确保***覆盖。
毫米波天线阵列，由于波长更短，天线阵子间距以及孔径更小，可以让更多的物理天线阵子集成在一个有限大小的二维天线阵列中，同时，由于毫米波天线阵列的尺寸有限，从硬件复杂度、成本开销以及功耗等因素考虑，无法采用数字波束赋形方式，而是通常采用模拟波束赋形方式，在增强网络覆盖同时，也可以降低设备的实现复杂度。
在2G/3G/4G***中，一个小区(扇区)使用一个较宽的波束(beam)来覆盖整个小区。因此在每个时刻，小区覆盖范围内UE都有机会获得***分配的传输资源。
NR的Multi-beam***通过不同的beam来覆盖整个小区，即每个beam覆盖一个较小的范围，通过时间上的sweeping来实现多个beam覆盖整个小区的效果。
例如一些不同beam上传输不同的同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH block，或称SSB)，UE可以通过不同的SSB来分辨出不同的beam。
又例如，一些不同的beam上传输不同的信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)，UE通过CSI-RS信号/CSI-RS资源来识别出不同的beam。
在一个multi-beam***中，物理下行控制信道(Physical Downlink Control Channel，PDCCH)和物理下行共享信道(Physical Downlink Shared Channel，PDSCH)可以通过不同的下行发送波束来传输。
为便于更好的理解本申请实施例，对本申请相关的CSI上报进行说明。
为了网络设备能够进行合理的调度，终端设备需要反馈CSI，以使网络设备确定传输层数、预编码矩阵、发送波束、调制编码方式等终端设备的调度信息。具体的，终端设备的CSI上报基于网络设备指示的CSI上报配置进行。每个CSI上报配置对应一个CSI上报，CSI中包含哪些内容通过CSI上报配置中的上报量信息(reportQuantity)来确定。例如，可以配置CSI上报量包括终端设备选择的参考信号(或者说，波束)的指示信息和/或，终端设备选择的参考信号(或者说，波束)的测量结果。
在一些实施例中，所述参考信号例如可以包括但不限于同步信号块(Synchronization Signal Block，SSB)、信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)。
需要说明的是，SSB也可以称为同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH block)。
在一些场景中，引入了物理上行控制信道(Physical Uplink Control Channel，PUCCH)小区组(PUCCH Cell Groups，PUCCH CG)概念。例如可以将所有被聚合的小区分为多个PUCCH CG，其中，包括特殊小区(SPCell)的PUCCH CG称为主PUCCH小区组(Primary PUCCH group)，其他PUCCH CG称为辅PUCCH小区组(Secondary PUCCH group)，PUCCH CG中携带PUCCH的辅小区(SCe11)称为PUCCH辅小区(PUCCH SCe11)。
其中，该SPcell可以指主小区(PCell)或者主辅小区(PScell)。
在NR***中，当在时隙n接收到一个SCell的激活命令时，那么终端设备最早在时间点时隙n+k可以向网络设备上报信道状态信息(Channel State Information，CSI)报告，该CSI报告用于向网络设备上报信号质量较优的参考信号。如图2所示，终端设备可以在时隙n+k和规定的激活时延需求之间激活该SCell，进一步地，在该SCell向网络设备上报CSI报告。
但是终端设备能够上报CSI报告的前提是该SCell所属的PUCCH group中的服务小区中至少有一个是激活的。当该SCell属于Secondary PUCCH group时，终端设备只有当该Secondary PUCCH group中的SCell激活之后才能够发送CSI报告，影响网络性能。因此，如何及时通知网络设备信号质量较优的参考信号是一项亟待解决的问题。
图3是根据本申请实施例的无线通信的方法200的示意性流程图，该方法200可以由图1所示的通信***中的终端设备执行，如图3所示，该方法200包括如下内容：
S210，在终端设备接收到第一信令的情况下，为第一辅小区触发波束失败恢复(beam failure recovery，BFR)，所述第一信令用于激活第一辅小区，第一辅小区为物理上行控制信道PUCCH辅小区(即PUCCH SCell)。
在本申请一些实施例中，所述第一信令为辅小区激活MAC CE(SCell
Activation/Deactivation MAC CE)，该辅小区激活MAC CE用于激活第一辅小区。
在本申请另一些实施例中，所述第一信令为无线资源控制(Radio Resource Control，RRC)信令，所述RRC信令用于配置PUCCH辅小区以及PUCCH辅小区的激活状态。
例如，RRC信令可以配置第一辅小区为PUCCH辅小区，配置该第一辅小区的激活状态参数(sCellState)为activated，以激活第一辅小区。
在本申请一些实施例中，所述第一辅小区属于辅PUCCH小区组，即Secondary PUCCH group。
在一些实施例中，在接收到第一信令之前，第一辅小区未激活，或者，第一辅小区所属的Secondary PUCCH group中没有激活的PUCCH SCell，因此，终端设备不能通过该Secondary PUCCH group中的PUCCH SCell向网络设备上报CSI报告。记为情况1。
在本申请一些实施例中，所述方法200还包括：
所述终端设备在第一服务小区上向所述网络设备发送BFR媒体接入控制控制元素MAC CE，其中，所述第一服务小区属于主PUCCH小区组，即Primary PUCCH group。
可选地，在第一辅小区未激活，或者，第一辅小区所属的Secondary PUCCH group中的PUCCH SCell均未激活的情况下，终端设备可以通过Primary PUCCH group中的服务小区为该第一辅小区触发BFR。通过该触发的BFR向网络设备上报CSI报告中所需上报的参考信号的信息。
在一些实施例中，所述BFR MAC CE包括以下中的至少一项：
所述第一辅小区的信息，至少一个参考信号的标识信息。
终端设备通过在所述BFR MAC CE中携带第一辅小区的信息，向网络设备指示通过第一服务小区发送的BFR MAC CE是为第一辅小区触发的BFR。

在一些实施例中，所述至少一个参考信号为候选参考信号列表(candidateBeamRSSCellList)中的参考信号，其中，所述候选参考信号列表是预配置的。

可选地，所述至少一个参考信号的信号质量采用物理层没有过滤的测量结果表征，例如层1-RSRP(L1-RSRP)等。
图4示出了一种BFR MAC CE的典型格式，例如，BFR MAC CE中可以包括候选参考信号列表中需要上报的候选参考信号的标识。
在另一些实施例中，终端设备也可以通过bitmap方式指示终端设备所上报的候选参考信号。例如，BFR MAC CE包括第二位图，该第二位图包括多个比特，每个比特对应候选参考信号列表中的一个候选参考信号，每个比特的取值用于指示对应的候选参考信号是否满足第一阈值，或者，终端设备是否上报该候选参考信号。比如，取值为1表示满足第一阈值，取值为0表示不满足第一阈值。假设候选参考信号列表包括8个候选参考信号(RS8～RS1)，若RS3是信号质量满足第一阈值的参考信号，第二位图包括B1～B8，分别对应RS8～RS1，则第二位图可以为00000100。
在一些实施例中，所述参考信号例如可以包括但不限于SSB、CSI-RS。
在本申请另一些实施例中，在接收到第一信令之前，第一辅小区已激活，或者，第一辅小区所属的Secondary PUCCH group中存在激活的PUCCH SCell。记为情况2。
在本申请一些实施例中，所述方法200还包括：

进一步地，所述方法200还包括：
所述终端设备在所述第一辅小区上向所述网络设备发送CSI报告，所述CSI报告包括至少一个参考信号的标识信息和/或所述至少一个参考信号的信号质量信息；或者
所述终端设备在第二辅小区上向所述网络设备发送CSI报告，所述CSI报告包括至少一个参考信号的标识信息和/或所述至少一个参考信号的信号质量信息，其中，第二辅小区可以为第一辅小区所属的Secondary PUCCH group中激活的PUCCH SCell。

又例如，在第一辅小区未激活，但是第一辅小区所属的Secondary PUCCH group中第二辅小区激活的情况下，在所述第二辅小区上向所述网络设备发送CSI报告。
即，在前述的情况2中，终端设备可以不为该第一辅小区触发BFR，而是在第一辅小区或第一辅小区所属的Secondary PUCCH group中激活的PUCCH SCell上向网络设备上报CSI报告。
综上所述，终端设备可以在接收到SCell的激活信令，但是该SCell还未激活，或者，该SChell所属的Secondary PUCCH group中没有激活的PUCCH SCell时，通过为该SCell触发BFR，以向网络设备上报需要通过CSI报告上报的参考信号的信息，而不需要等待该Schell激活之后再上报该参考信号的信息，从而能够保证网络设备及时获知终端设备所选择的信号质量较优的参考信号的信息，提升网络性能。
