Description

通信方法和通信装置
本申请要求于2018年10月26日提交中国专利局、申请号为201811256992.9、申请名称为“通信方法和通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，并且更具体地，涉及一种通信方法和通信装置。
背景技术
基于波束的通信能带来更高的天线增益，特别是在高频通信环境，基于波束的通信能够克服高频信号的快速衰减。
通信系统中，例如5G NR通信系统中，如果基站和终端都用了波束，就需要有一个让两端波束对准(beam alignment)的机制，否则基站与终端之间不能通信，这个机制在通信协议里叫波束管理(beam management)。
波束失败恢复(beam failure recovery，BFR)是波束管理的一个功能。当原本互相对准的基站波束和终端波束不能正常通信，例如，原本相互对准的基站波束和终端波束之间被障碍物(比如人体、车辆)挡住的时候，需要重新寻找新的可以互相对准的一对波束，以保证基站与终端之间的通信可以继续。该重新寻找可以通信的波束的过程就可以称为波束失败恢复。波束失败恢复可以简称为波束恢复。
波束失败恢复可以包括以下几个步骤：
(1)波束失败检测(beam failure detection)，即终端监视控制信道质量，如果控制信道质量连续低于某个门限并且持续一定时间，则认为发生波束失败；
(2)发现新的可用波束，即终端从备选波束(candidate beam)的集合中选择一个满足条件的备选波束作为新的可用波束，其中，该备选波束的集合可以是基站配置给终端的，可用波束满足的条件可以是波束质量高于给定备选波束质量门限；
(3)波束失败恢复请求(beam failure recovery request，BFRQ)，即终端将其发现的新的可用波束的编号通过与该备份波束编号关联的随机接入信道(random access channel，RACH)向基站通知发生波束失败，并且通过该RACH把该波束的编号通知给基站，然后把终端的波束切换到该可用的波束上，等待基站响应；
(4)波束失败恢复响应(beam failure recovery response)，即基站收到BFRQ以后，把自己的波束切换到终端通知的那个波束上，并在这个波束上面发一个响应；
(5)如果终端收到了基站发送的波束失败恢复响应，那么就完成了波束失败的恢复。
在载波聚合(carrier aggregation，CA)的场景下，也可以应用波束管理技术。具体地，在CA的场景下，也可以应用波束失败恢复流程。
例如，终端设备上会预先配置主小区(primary cell，Pcell)中的每个备选波束与随机 接入信道(random access channel，RACH)资源的关联关系，并在主小区检测到波束失败时，使用与选择的主小区中的备选波束预先关联的RACH资源向基站发送波束恢复请求消息。
但是，现有的波束失败恢复流程中，没有为辅小区(secondary cell，Scell)配置上行传输，例如没有为辅小区中的波束配置相关联的上行资源，这导致了终端设备在辅小区中检测到波束失败时，不知道应使用哪些RACH资源向基站发送波束恢复请求消息，从而影响终端设备在辅小区中的波束失败恢复的实现。
因此，如何实现终端设备在辅小区中的波束失败恢复，是一个亟待解决的技术问题。发明内容
本申请提供通信方法和通信装置，可以使得终端设备在小区中检测到波束失败时，可以实现波束失败恢复。

为便于理解本申请实施例，首先结合图1详细说明适用于本申请实施例的通信系统。
图1是适用于本申请实施例的通信系统的示意图。如图1所示，终端设备110可以位于小区130和小区140的覆盖范围内。应理解，图1所示的小区130和小区140仅是一种示例，终端设备110可以位于更多的小区的覆盖范围内。
应理解，图1所示的通信系统仅是一种示例，小区130与小区140的覆盖符号可以完全重合，或者小区130可以位于小区140的覆盖范围内。
如图1所示，该通信系统包括至少一个网络设备120和至少一个终端设备110。在该通信系统中，终端设备和网络设备可以通过波束管理过程获得通信较优的一个或多个波束对，波束对为<Bx，B’x>以及<By,B’y>，其中Bx代表网络设备的发送波束，B’x代表终端设备的接收波束，By代表终端设备的发送波束，B’y代表网络设备的接收波束。
例如，参见图1，网络设备的发送波束#1和终端设备的接收波束#0为一个波束对，网络设备的发送波束#2和终端设备的接收波束#2为一个波束对。终端设备的发送波束#0和网络设备的接收波束#1为一个波束对，终端设备的发送波束#1和网络设备的接收波束#2为一个波束对。
在该通信系统中需要终端设备110和网络设备120的波束对齐才能进行正常的通信。 由于终端设备和网络设备都能各自朝向多个波束方向，因此进行通信的前提是需要有正确的波束指示。具体来讲，在下行通信中，网络设备需要通知终端设备应该使用什么接收波束接收接下来网络设备发送的信号，或者通知终端设备接下来网络设备发送的信号是使用什么发送波束发送的。在上行通信中，网络设备需要通知终端设备应该使用什么发送波束发送上行信号，或者通知终端设备网络设备会使用什么样的接收波束来接收终端发出的信号。比如，在下行传输中，网络设备可以通知终端设备该网络设备使用发送波束#1进行传输，那么终端设备需要使用接收波束#0进行接收。或者，网络设备使用发送波束#1进行传输，并且通知终端设备使用接收波束#0进行接收。再如，在上行传输中，网络设备可以通知终端设备使用发送波束#0进行传输，那么网络设备将使用接收波束#1进行接收。或者，网络设备可以通知该网络设备使用的接收波束为接收波束#0，从而终端设备需要使用发送波束#0进行传输。
为便于理解本申请实施例，下面对本申请中涉及的几个术语做简单介绍。
1、波束：波束是一种通信资源。波束可以是宽波束，或者窄波束，或者其他类型波束。形成波束的技术可以是波束成形技术(beamforming)或者其他技术手段。波束成形技术可以具体为数字波束成形技术，模拟波束成形技术，混合数字/模拟波束成形技术。不同的波束可以认为是不同的资源。通过不同的波束可以发送相同的信息或者不同的信息。可选的，可以将具有相同或者类似的通信特征的多个波束视为是一个波束。一个波束内可以包括一个或多个天线端口，用于传输数据信道，控制信道和探测信号等。
波束，也可以理解为空间资源，可以是指具有能量传输指向性的发送或接收预编码向量。能量传输指向性可以指在一定空间位置内，接收经过该预编码向量进行预编码处理后的信号具有较好的接收功率，如满足接收解调信噪比等，能量传输指向性也可以指通过该预编码向量接收来自不同空间位置发送的相同信号具有不同的接收功率。同一设备(例如网络设备或终端设备)可以有不同的预编码向量，不同的设备也可以有不同的预编码向量，即对应不同的波束，针对设备的配置或者能力，一个设备在同一时刻可以使用多个不同的预编码向量中的一个或者多个，即同时可以形成一个波束或者多个波束。从发射和接收两个角度出发，波束可以分为发射波束和接收波束。
发射波束：是指通过多天线采用波束成形技术发射具有方向性的波束。
接收波束：是指接收信号的方向上也具有指向性，尽可能指向发射波束的来波方向，以进一步提高接收信噪比并避免用户间的干扰。
波束也可以称为空域滤波器(spatial filter)，或者称空间滤波器(spatial filter)或空间参数(spatial parameters)，发射波束也可以称为空域发射滤波器，接收波束也可以称为空域接收滤波器。
2、波束配对关系：即，发射波束与接收波束之间的配对关系，也就是空间发射滤波器与空间接收滤波器之间的配对关系。在具有波束配对关系的发射波束和接收波束之间传输信号可以获得较大的波束赋形增益。
在一种实现方式中，发送端和接收端可以通过波束训练来获得波束配对关系。具体地，发送端可通过波束扫描的方式发送参考信号，接收端也可通过波束扫描的方式接收参考信号。具体地，发送端可通过波束赋形的方式在空间形成不同指向性的波束，并可以在多个具有不同指向性的波束上轮询，以通过不同指向性的波束将参考信号发射出去，使得参考 信号在发射波束所指向的方向上发射参考信号的功率可以达到最大。接收端也可通过波束赋形的方式在空间形成不同指向性的波束，并可以在多个具有不同指向性的波束上轮询，以通过不同指向性的波束接收参考信号，使得该接收端接收参考信号的功率在接收波束所指向的方向上可以达到最大。
3、参考信号(reference signal，RS)与参考信号资源：参考信号可用于信道测量或者信道估计等。参考信号资源可用于配置参考信号的传输属性，例如，时频资源位置、端口映射关系、功率因子以及扰码等，具体可参考现有技术。发送端设备可基于参考信号资源发送参考信号，接收端设备可基于参考信号资源接收参考信号。
本申请中涉及的信道测量也包括波束测量，即通过测量参考信号获得波束质量信息，用于衡量波束质量的参数包括参考信号接收功率(reference signal receiving power，RSRP)，但不限于此。例如，波束质量也可以通过参考信号接收质量(reference signal receiving quality，RSRQ)，信噪比(signal-noise ratio，SNR)，信号与干扰噪声比(signal to interference plus noise ratio，SINR)，块误码率(block error rate，BLER)，信号质量指示(channel quality indicator，CQI)等参数衡量。本申请实施例中，为方便说明，在未作出特别说明的情况下，所涉及的信道测量可以视为波束测量。
参考信号例如可以包括信道状态信息参考信号(channel state information reference signal，CSI-RS)、同步信号块(synchronization signal block，SSB)以及探测参考信号(sounding reference signal，SRS)。与此对应地，参考信号资源可以包括CSI-RS资源(CSI-RS resource)、SSB资源、SRS资源(SRS resource)。
需要说明的是，上述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)，所对应的SSB资源也可以称为同步信号/物理广播信道块资源(SS/PBCH block resource)，可简称为SSB resource。
为了区分不同的参考信号资源，每个参考信号资源可对应于一个参考信号资源的标识，例如，CSI-RS资源标识(CSI-RS resource indicator，CRI)、SSB资源标识(SSB resource indicator，SSBRI)、SRS资源索引(SRS resource index，SRI)。其中，SSB资源标识也可以称为SSB标识(SSB index)。
应理解，上文中列举的参考信号以及相应的参考信号资源仅为示例性说明，不应对本申请构成任何限定，本申请并不排除在未来的协议中定义其他参考信号来实现相同或相似功能的可能。
4、波束指示信息：用于指示传输所使用的波束的信息。包括发送波束和/或接收波束。波束指示信息可以是下述中一种或多种：波束号(或者说编号、索引(index)、标识(identity，ID)等)、上行信号资源号，下行信号资源号、波束的绝对索引、波束的相对索引、波束的逻辑索引、波束对应的天线端口的索引、波束对应的天线端口组索引、波束对应的下行信号的索引、波束对应的下行同步信号块的时间索引、波束对连接(beam pair link，BPL)信息、波束对应的发送参数(Tx parameter)、波束对应的接收参数(Rx parameter)、波束对应的发送权重、波束对应的权重矩阵、波束对应的权重向量、波束对应的接收权重、波束对应的发送权重的索引、波束对应的权重矩阵的索引、波束对应的权重向量的索引、波束对应的接收权重的索引、波束对应的接收码本、波束对应的发送码本、波束对应的接收码本的索引、波束对应的发送码本的索引中的至少一种。其中，下行信号可以是下述中 的一种或多种：同步信号、广播信道、广播信号解调信号、同步信号广播信道块(synchronous signal/PBCH block，SSB)、信道状态信息参考信号(channel state information reference signal，CSI-RS)、小区专用参考信号(cell specific reference signal，CS-RS)、UE专用参考信号(user equipment specific reference signal，US-RS)、下行控制信道解调参考信号(dedicated reference signal，DMRS)，下行数据信道解调参考信号，下行相位噪声跟踪信号中任意一种。上行信号可以是下述中的一种或多种：上行随机接入序列，上行探测参考信号(sounding reference signal，SRS)，上行控制信道解调参考信号，上行数据信道解调参考信号，上行相位噪声跟踪信号任意一种。
波束指示信息还可以体现为传输配置编号(transmission configuration index，TCI)或者TCI状态。一个TCI状态包括一个或多个QCL信息，每一个QCL信息包括一个参考信号(或同步信号块)的ID和一种QCL类型。例如：终端设备可以需要根据网络设备指示的TCI状态(通常由物理下行控制信道(physical downlink control channel，PDCCH)携带)来确定接收物理下行共享信道(physical downlink shared channel，PDSCH)的波束。
5、准共址(quasi-co-location，QCL)：或者称准同位。准同位关系用于表示多个资源之间具有一个或多个相同或者相类似的通信特征，对于具有同位关系的多个资源，可以采用相同或者类似的通信配置。具体的。具有QCL关系的天线端口对应的信号中具有相同的参数，或者，一个天线端口的参数(也可以称为QCL参数)可用于确定与该天线端口具有QCL关系的另一个天线端口的参数，或者，两个天线端口具有相同的参数，或者，两个天线端口间的参数差小于某阈值。其中，所述参数可以包括以下一项或多项：时延扩展(delay spread)，多普勒扩展(Doppler spread)，多普勒频移(Doppler shift)，平均时延(average delay)，平均增益，空间接收参数(spatial Rx parameters)。其中，空间接收参数可以包括以下的一项或多项：到达角(angle of arrival，AOA)、平均AOA、AOA扩展、离开角(angle of departure，AOD)、平均离开角AOD、AOD扩展、接收天线空间相关性参数、发送天线空间相关性参数、发射波束、接收波束以及资源标识。
空域准同位(spatial QCL)：spatial QCL可以认为是QCL的一种类型。对于spatial，可以分别从发送端或接收端角度进行理解：从发送端来看，如果两个天线端口是空域准同位的，即是指这两个天线端口的对应的波束方向在空间上是一致的；从接收端来看，如果两个天线端口是空域准同位的，则是指接收端能够在相同的波束方向上接收到这两个天线端口发送的信号。
6、准同位假设(QCL assumption)：是指假设两个端口之间是否具有QCL关系。准同位假设的配置和指示可以用来帮助接收端进行信号的接收和解调。例如接收端能假设A端口和B端口具有QCL关系，即可以将A端口上测得的信号的大尺度参数用于B端口上的信号测量和解调。大尺度参数可以包括上述的天线端口的参数。
7、模拟波束成型，可以通过射频实现。例如，一个射频链路(RF chain)通过移相器来调整相位，从而控制模拟波束方向的改变。因此，一个RF chain在同一时刻只能打出一个模拟波束。
基于模拟波束的通信，需要发送端和接收端的波束对齐，否则无法正常传输信号。因此，当网络设备与终端设备之间通过波束进行通信时，终端设备需要对网络设备发送的多个波束进行测量以选择其中较优的波束，并将该较优的波束上报给网络设备，该波束将用 于网络设备与终端设备之间的后续通信。
终端设备对网络设备发送的多个波束进行测量之后，通常会根据RSRP最强原则进行上报波束的选择，即，通过测量，终端设备将RSRP较强的多个波束上报给网络设备，该RSRP较强的多个波束将用于网络设备与终端设备之间的后续通信。
8、载波聚合(carrier aggregation，CA)，可以将两个或多个成员载波(component carrier，CC))聚合在一起，实现更大的传输带宽，有效提高上下行传输速率。CA可以支持带内连续载波聚合、带内不连续载波聚合或带间不连续载波聚合等。其中，成员载波也可以称为载波分量(carrier component，CC)。
9、带宽部分(bandwidth part,BWP)：可以理解为一段连续的频带，该频带包含至少一个连续的子带，每个带宽部分可以对应一组系统参数(numerology)，包括例如但不限于，子载波间隔、循环前缀(cyclic prefix，CP)长度、传输时间间隔(transmission time interval,TTI)、符号(Symbol)个数、资源块(resource block，RB)位置、时隙长度和帧格式等。不同带宽部分可以对应不同的系统参数。
应注意的是本申请的各个实施例中，小区与载波分量可以等效替换，因为在通信协议中，一个CC通常被当做一个独立的小区。CC、带宽部分、CC/BWP、CC和/或BWP也可以等效替换，因为它们都可以用于描述一端频域资源。
10、主小区，工作在主频段上，终端设备在使用主小区执行初始连接或者重建连接。
11、辅小区组(secondary cell group，SCG)：对于配置了双连接的终端设备，一个包含主辅小区(primary SCG cell)和其他辅小区的服务小区的子集。
12、主辅小区：对于双连接操作，主辅小区指终端设备执行同步重配时发送随机接入的小区。
13、特殊小区：对于双连接操作，特殊小区指主小区组(master cell group，MCG)的主小区或者辅小区组的主辅小区，否则，特殊小区为主小区。
14、辅小区：如果终端设备配置了CA功能，在特殊小区之外提供额外的无线资源的小区。
15、服务小区：对于无线资源控制链接(RRC_CONNECTED)状态的终端设备，如果没有配置CA或双连接(dual-connectivity，DC)，只有一个服务小区，即主小区；如果配置了CA或DC，服务小区包括特殊小区和所有辅小区的结合。
16、波束失败恢复请求消息，用于终端设备在检测到波束失败时，向网络设备通知所述终端设备出现了波束失败问题。应理解，本申请实施例中，波束失败恢复请求消息可以与BFRQ相互替换。
上述各个术语的定义可以参考现有技术。但随着技术的不断发展，上述定义也有可能发生变化。
为便于理解本申请实施例，下面对本申请中涉及的几个概念做简单介绍。
第一小区，是指终端设备检测到波束失败的小区。第一小区可以是覆盖终端设备的多个小区中的任意一个。例如，第一小区可以是辅小区。
第二小区，是指终端设备发送波束失败恢复请求消息的小区。第二小区可以是覆盖终端设备的多个小区中的任意一个。例如，第二小区可以是主小区。
第一小区和第二小区所使用的频段、带宽或者说载波分量可以不同。第一小区与第二 小区可以相邻，也可以不相邻。第一小区和第二小区可以由同一个网络设备提供服务，也可以由不同的网络设备提供服务。
第一波束，是第一小区中的一个或多个波束。第一波束是由网络设备显式或隐式地配置给终端设备监测通信质量的，例如，控制信道质量。例如，终端设备在第一小区中连续N次检测到控制信道质量低于给定波束失败门限，则判断波束失败。
第二波束，是指终端设备与网络设备通信可以使用的波束。第二波束可以是第一小区中的波束，也可以是其他小区中的波束。或者，第二波束可以是预先配置的备选波束集合中的波束，也可以是该备选波束集合以外的波束。
例如，第二波束可以是终端设备测量同步信号块(synchronization signal block，SSB)或测量信道状态信息参考信号(channel status information reference signal，CSI-RS)或测量其他信号之后，根据测量结果确定的。
第二资源，是指终端设备使用第一资源发送波束恢复失败请求消息之后，发送上行信道应使用的资源，该上行信道中携带第二波束的信息。其中，上行信道可以包括PUCCH或PUSCH。
第二波束的信息可以包括以下信息中的一种或多种：第二波束的标识、第二波束的质量、第二波束对应的载波分量的标识、第二波束对应的带宽部分的标识或第二波束对应的参考信号的类型。
其中，若第二波束为备选波束集合以外的波束，则第二波束的标识可以是第二用波束的全局标识。若第二波束为备选波束集合中的波束，则第二波束的标识可以是第二波束的局部标识，也可以是全局标识。
第二资源与第一资源之间是具有关联关系的。也就是说，终端设备在哪些第二资源上发送携带第二波束信息的上行信道，与终端设备在哪些第一资源上发送波束恢复失败请求消息是有关联的。
第一信息，是指包括第二资源信息的信息。也就是说，第一信息中包括了用于发送上行信道的资源的信息，该上行信道中携带第二波束的信息。
因为第一信息包括了第二资源信息，因此，第二资源与第一资源之间的关联关系，也可以称为第一信息与第一资源之间的关联关系。进一步地，第一信息与第一资源之间的关联关系，可以称为第一信息与使用第一资源发送的波束失败恢复请求消息之间的关联关系，可以简称为第一信息与波束失败恢复请求消息的对应关系。
或者，第一信息与波束失败恢复请求消息的对应关系也可以称为第一信息与第二小区的对应关系。例如，在不同的小区中发送波束失败恢复请求消息之后，可以根据该小区对应的第一信息来发送上行信道。
或者，第一信息与波束失败恢复请求消息的对应关系可以称为第一信息与第二波束的对应关系。例如，终端设备确定不同的第二波束之后，可以根据第二波束对应的第一信息来发送上行信道。
或者可以说，在本申请实施例中，涉及第一信息与波束失败恢复请求消息的对应关系的内容中，第一信息可以替换为第二资源或上行信道，波束失败恢复请求消息可以替换为第一资源、第二波束或第二小区。
第一信息与波束失败恢复请求消息之间可以是一对一、一对多、多对一或者多对多的 对应关系。
例如，使用不同的第一资源发送的波束恢复请求消息之后，发送携带第二波束信息的上行信道所使用的第二资源不同，即波束失败恢复请求消息与第一信息之间是一对一的对应关系。
例如，使用不同的第一资源发送的波束恢复请求消息之后，发送携带第二波束信息的上行信道所使用的第二资源相同，即波束失败恢复请求消息与第一信息之间是多对一的对应关系。
例如，使用相同的第一资源发送波束恢复请求消息之后，发送携带第二波束信息的上行信道所使用的第二资源不相同，即波束失败恢复请求消息与第一信息之间是一对多的对应关系。
第一信息可以为上报配置(ReportConfig)信息、资源集合/资源设置(Resource setting或Resource set)信息、触发状态(trigger state)信息或上行信道的信息中的一种或多种。
第一信息可以包括第一指示信息和/或第二指示信息，第一指示信息用于指示终端设备使用第一资源发送的波束失败恢复请求消息与发送携带第二波束信息的上行信道之间的时间间隔，第二指示信息用于指示终端设备发送所述上行信道所使用的目标波束的信息。
所述目标波束的信息可以包括以下信息中的一种或多种：目标波束的标识、目标波束的质量、目标波束对应的载波分量的标识、目标波束对应的带宽部分的标识或目标波束对应的参考信号的类型。
终端设备使用第二资源发送所述上行信道所使用的目标波束，与终端设备使用相关联的第一资源发送波束失败恢复请求消息所使用的波束可以相同，也可以不相同。
例如，第二指示信息可以用于指示：不论是否为所述上行信道配置了发送波束，终端设备均使用用于所述波束恢复失败恢复请求消息的波束来发送所述上行信道；或者，第二指示信息可以用于指示：如果为所述上行信道配置了发送波束，则使用该发送波束来发送所述上行信道，否则使用用于所述波束恢复失败恢复请求消息的波束来发送所述上行信道。
应注意的是，本申请的实施例中的波束失败恢复请求消息，还可以用于激活网络设备在第二资源上接收上行信道，该上行信道中携带第二波束的信息。此外，所述波束失败恢复请求消息还可以用于通知网络设备不应在第二资源上调度其他终端设备的上行传输。
本申请实施例中的配置信息中包括第一信息与波束失败恢复请求消息的对应关系。该置信息可以携带在广播信道、系统消息传输、系统消息更新，层一(例如，物理层)控制信令、高层信令中的一种信令或者多种信令构成的组合信令中。
示例性地，该物理层信息可以为下行控制信息(downlink control information，DCI)，该高层信令可以为无线资源控制(radio resource control，RRC)信令或媒体接入控制控制单元(media access control control element，MAC CE)信令。
该配置信息中还可以包括第一信息。
该配置信息中还可以包括第二信息，第二信息用于指示终端设备在第一小区中检测到波束失败时，在第二小区中发送波束失败恢复请求消息。
该配置信息中还可以包括第三信息，第三信息用于指示终端设备在第二小区中用于发 送波束失败恢复请求消息的第一资源。或者可以说，第三信息用于指示第一资源信息，即指示终端设备在第二小区中使用哪些第一资源发送波束失败恢复请求消息。
该配置信息中还可以包括第四信息，第四信息用于指示终端设备确定的第二波束所属的范围。例如，第四信息可以用于指示终端设备在预先配置的备选波束集合中确定第二波束。或者，第四信息可以用于指示终端设备在备选波束集合以外确定第二波束，例如，第四信息可以用于指示终端设备测量SSB或测量配置给该终端设备的周期性的CSI-RS，以根据测量结果确定第二波束。
本申请实施例的上行信道为PUCCH时，上行信道的信息的可以包括但不限于以下一种或多种信息：PUCCH资源的标识(identification，ID)；PUCCH使用的时频资源；PUCCH的发送波束；功率相关的参数(包括发送功率的基准值和路损补偿值等)；PUCCH的格式和/或内容(例如候选波束的ID；候选波束的质量；PUCCH对应的BWP/CC的ID；候选RS类型)；PUCCH与BFRQ RACH在时间上的关联关系，例如，在BFRQ RACH发送后的X时间激活该PUCCH的发送；PUCCH与BFRQ RACH在波束上的关联关系，例如，如果该PUCCH资源本身配置有发送波束，则使用该配置的发送波束来发送该PUCCH，或者，与BFRQ RACH使用相同的发送波束(即使该PUCCH资源本身配置有发送波束，也使用BFRQ RACH的发送波束来发送该PUCCH)。
其中，PUCCH与BFRQ RACH在时间上的关联关系即为第一指示信息，PUCCH与BFRQ RACH在波束上的关联关系即为第二指示信息，候选波束即为第二波束。
当第一信息为上述PUCCH的信息时，波束失败恢复请求消息与第一信息的对应关系，具体可以通过PUCCH资源的标识与波束失败恢复请求消息的对应关系。终端设备根据波束失败恢复请求消息与“PUCCH资源的标识”的对应关系确定终端设备在第二小区中发送的波束失败恢复请求消息相对应的“PUCCH资源的标识”之后，可以根据该“PUCCH资源的标识”对应的上行信道信息来发送PUCCH。PUCCH资源标识与波束失败恢复请求消息的对应关系可以简称为PUCCH与BRRQ RACH的对应关系。PUCCH与BFRQ RACH资源可以是一一对应，一对多，多对一，多对多的对应关系。
本申请实施例的上行信道为PUSCH时，上行信道的信息可以参考上行信道为PUCCH时所包括的内容，此处不再赘述。
本申请实施例中，上行信道为PUCCH时，上报配置信息可以包括但不限于以下信息：上报配置的标识；上报的CC/BWP的标识；上报类型(周期性的上报，半持续的上报，非周期性的上报等)；PUCCH对应的BWP；PUCCH资源的标识；上报所在时间点相关的参数(包括上报时隙，符号，偏移量等)；上报所用功率相关的参数(包括发送功率的基准值和路损补偿值等)；上报量，例如CSI-RS资源标识+波束质量、SSB索引+波束质量、波束编号、波束编号+波束质量等不同的上报量中的一种或多种；上报的频域位置；是否分组上报；上报的波束数目；波束管理资源设置；干扰管理资源设置。可选的，上报配置信息中还可以包括上报使用的上行信道是PUCCH还是PUSCH的指示信息；上行信道为PUCCH时，还可以包括PUCCH资源的标识。
其中，上报量即为第二波束的信息，例如，“CSI-RS资源标识+波束质量”用于指示第二波束是根据该CSI-RS资源标识对应的CSI-RS测量得到的，其中的波束质量即为第二波束的信号质量。
当第一信息为上述上报配置信息时，波束失败恢复请求消息与第一信息的对应关系，具体可以通过波束失败恢复请求消息与“上报配置的标识”的对应关系来体现。终端设备根据波束失败恢复请求消息与“上报配置的标识”的对应关系确定终端设备在第二小区中发送的波束失败恢复请求消息相对应的“上报配置的标识”之后，可以根据该“上报配置的标识”对应的上报配置信息中记录的信息来发送上行信道。可选的，如果该上报配置用于正常的波束上报，终端设备在发送了波束失败恢复请求消息之后可以放弃正常的波束上报，而按照上报配置的指示发送用于波束失败恢复的信息，例如第一小区的可用波束的信息等。
本申请实施例中的资源设置信息可以包括但不限于以下信息：资源设置的标识。该资源设置的标识与上报设置信息中包括的资源设置的标识相对应。
当第一信息为上述资源设置信息时，波束失败恢复请求消息与第一信息的对应关系，具体可以通过波束失败恢复请求消息与“资源设置的标识”的对应关系来体现。终端设备根据波束失败恢复请求消息与“资源设置的标识”的对应关系确定终端设备在第二小区中发送的波束失败恢复请求消息相对应的“资源设置的标识”之后，可以根据该“资源设置的标识”对应的资源设置来发送上行信道，例如通过该资源设置的标识关联的上报设置信息来确定发送上行信道。
本申请实施例的触发状态信息可以包括但不限于以下信息：触发状态的标识；该触发状态关联的上报设置的标识，可以关联一个或多个上报设置的标识。
当第一信息为上述触发状态信息时，波束失败恢复请求消息与第一信息的对应关系，具体可以通过波束失败恢复请求消息与“触发状态的标识”的对应关系来体现。终端设备根据波束失败恢复请求消息与“触发状态标识”的对应关系确定终端设备在第二小区中发送的波束失败恢复请求消息相对应的“触发状态的标识”之后，可以根据该“触发状态的标识”对应的触发状态信息中包括的上报设置的标识所关联的上报设置信息来发送上行信道。
可选地，上述触发状态信息中还可以包括：该触发状态关联的资源设置的标识。此时，终端设备确定相关联的上报设置信息之后，还可以根据该资源设置的标识确定对应的资源设置信息，并根据该资源设置信息来发送上行信道。
可选的，如果该触发状态用于正常的波束上报，终端设备在发送了波束失败恢复请求消息之后可以放弃正常的波束上报，而按照上报配置的指示发送用于波束失败恢复的信息，例如第一小区的可用波束的信息等。
下面将结合附图详细说明本申请实施例。
图2是从设备交互的角度示出的通信方法的示意性流程图。如图所示，图2中示出的通信方法可以包括步S201至S205。
应理解，在本申请实施例中，以终端设备和网络设备作为执行本申请实施例通信方法的执行主体为例，对本申请实施例的通信方法进行说明。作为示例而非限定，执行本申请实施例的通信方法的执行主体也可以是应用于终端设备的芯片和应用于网络设备的芯片。
S201，网络设备发送配置信息，所述配置信息包括波束失败恢复请求消息与第一信息的对应关系。相对应地，终端设备接收该配置信息。
其中，每个波束失败恢复请求消息可以对应一个第一信息，或者可以说，波束失败恢 复请求消息与第一信息是一一对应的关系，或者可以说，每个第一资源对应一个第二资源。
S202，终端设备在第一小区检测到第一波束失败。
此外，终端设备还可以确定第二波束。例如，终端设备可以将第一小区中的可用波束确定为第二波束。
其中，终端设备可以将配置的备选波束集合中的波束确定为第二波束，也可以测量没有配置在备选波束集合中的波束，并根据测量结果确定第二波束。例如，终端设备可以测量第一小区中的SSB、其他小区中的SSB或者其他配置给该终端设备的周期性的CSI-RS，并将信号质量高于给定信号阈值的信号对应的波束确定为第二波束。
S203，终端设备在第二小区发送波束失败恢复请求消息。相应地，网络设备接收所述波束失败恢复请求消息。
例如，若配置信息中包括第二信息，则终端设备根据第二信息的指示，在第二小区发送波束失败恢复请求消息。
进一步地，终端设备在第二小区，可以使用第一资源发送波束失败恢复请求消息。
例如，若配置信息中包括第三信息，则终端设备在第二小区，使用第三信息指示的第二资源发送波束失败恢复请求消息。
应理解，该步骤中的网络设备与S201中的网络设备可以是同一个网络设备，也可以是不同的网络设备。
S204，终端设备根据所述配置信息中的所述对应关系，确定与所述波束失败恢复请求消息对应的第一信息。
其中，若配置信息包括的是波束失败恢复请求消息与第一信息的一一对应关系，则终端设备根据所述对应关系，能够确定与所述波束失败恢复请求消息对应的第一信息。
S205，终端设备根据所述第一信息，在所述第二小区发送上行信道，所述上行信道中携带所述第一小区中的第二波束的信息。相应地，网络设备接收该上行信道，以接收该第二波束的信息。
可选的，如果S202步骤中终端设备没有确定第二波束，即没有在第一小区进行新波束发现的操作，终端设备可以通过第二小区发送上行信道，所述上行信道中携带第一小区波束失败的信息。其中，第一小区波束失败的信息可以是第一波束标识以及一个波束质量上报异常标识。
应理解，该网络设备与S203中的网络设备可以是同一个网络设备。
终端设备根据所述第一信息，在所述第二小区发送上行信道，可以包括：终端设备在所述第二小区，使用所述第一信息所指示的第二资源发送上行信道。也就是说，终端设备发送所述上行信道的第二资源可以不是经过网络设备通过上行授权调度的。
例如，所述第一信息包括第一指示信息，所述第一指示信息用于指示所述终端设备发送所述波束失败恢复请求消息与发送所述上行信道之间的时间间隔时，所述终端设备在发送所述波束失败恢复请求消息之后，经过所述第一指示信息指示的所述时间间隔，发送所述上行信道。
例如，所述第一信息包括第二指示信息，所述第二指示信息用于指示所述终端设备发送所述上行信道所使用的目标波束的信息时，所述终端设备在发送所述波束失败恢复请求消息之后，使用所述目标波束发送所述上行信道。
例如，所述第一信息包括第一指示信息和第二指示信息，所述第一指示信息用于指示所述终端设备发送所述波束失败恢复请求消息与发送所述上行信道之间的时间间隔，所述第二指示信息用于指示所述终端设备发送所述上行信道所使用的目标波束的信息时，所述终端设备在发送所述波束失败恢复请求消息之后，经过所述第一指示信息指示的所述时间间隔，使用所述目标波束发送所述上行信道。
图2所示的通信方法中，还可以包括S206，即网络设备发送针对所述波束失败恢复请求消息和/或所述上行信道的响应。相应地，终端设备监测网络设备的所述响应。
现有技术中，通常情况下，终端设备会在发送波束恢复请求消息(例如RACH)之后的4个时隙(slot)开始监测网络设备的响应。
但在本申请实施例中，由于波束失败恢复请求消息(例如RACH)的发送关联了上行信道(例如PUCCH/PUSCH)的发送，所以不再适合从发送波束失败恢复请求消息之后开始计时。
假设终端设备在时隙n发送了波束失败恢复请求消息,在时隙n+X发送了上行信道，那么可以规定终端设备在时隙n+X+Y开始监测网络设备对波束失败恢复请求消息和相关联的上行信道的响应。其中，X即为第一指示信息指示的时间间隔。
另外，需要注意的有以下几点：
(1)上下行传输的子载波间隔(sub-carrier spacing，SCS)不同会导致的上下行时间单位不同。例如，如果下行传输的子载波间隔为120千赫兹(kHz)，那么一个下行时隙是0.125毫秒(ms)，如果上行传输的SCS为60kHz，那么一个上行时隙是0.25ms，这样就会出现上下行时隙号不同的问题。
针对该问题，一种可能的解决方法是使用绝对时间，例如使用ms来标识时间点；另一种可能的解决方法是规范统一使用上行或者下行的时隙号，例如，规范在时隙n发送波束失败恢复请求消息，在时隙n+X发送上行信道，在时隙n+X+Y监测网络设备的响应中的实现都是指的下行时隙；另一种可能的解决方法是对上下行时间单位进行换算。
(2)终端设备监测网络设备响应的波束可以包括以下可能：监测与发送波束失败恢复请求消息的波束对应的接收波束；监测欲发送上行信道的波束所对应的接收波束。
(3)终端设备监测网络设备响应的小区可以包括以下可能：监测第一小区的波束失败恢复专用资源集合(CORESET)和/或搜索空间(Search space)；监测第二小区上的第一小区波束失败恢复专用资源集合和/或搜索空间；监测第二小区上的正常资源集合和/或搜索空间，即非波束失败恢复专用的资源集合和/或搜索空间。
(4)网络设备响应的具体内容可以包括以下可能：确认波束失败恢复功能完成；通过调度触发一次第一小区的波束测量和上报；通过调度触发一次第一小区基于终端设备上报的可用波束的信道信息测量和上报；通过调度重新配置第一小区的波束信息，例如包括上下行数据/控制信道的波束配置。
本申请另一个实施例的通信方法的可以包括S301至S306。
应理解，在本申请实施例中，以终端设备和网络设备作为执行本申请实施例通信方法的执行主体为例，对本申请实施例的通信方法进行说明。作为示例而非限定，执行本申请实施例的通信方法的执行主体也可以是应用于终端设备的芯片和应用于网络设备的芯片。
S301至S306可以参考S201至S206，为了简洁，下面重点介绍该实施例中与S201 至S206中不同的内容。
其中，网络设备向终端设备发送的所述配置信息包括的是多个波束失败恢复请求消息与第一信息的对应关系，即每个波束失败恢复请求消息都有对应的第一信息，并且多个波束失败恢复请求消息对应同一个第一信息。
多个波束失败恢复请求消息与第一信息的对应关系，可以理解为：多个第一资源对应同一个第一信息，即多个第一资源对应同一个第二资源，即使用不同的第一资源发送波束失败恢复请求消息时，可以使用相同的第二资源发送上行信道。或者可以说，波束失败恢复请求消息与第一信息是多对一的对应关系。
本申请另一个实施例的通信方法的可以包括S401至S406。
应理解，在本申请实施例中，以终端设备和网络设备作为执行本申请实施例通信方法的执行主体为例，对本申请实施例的通信方法进行说明。作为示例而非限定，执行本申请实施例的通信方法的执行主体也可以是应用于终端设备的芯片和应用于网络设备的芯片。
S401至S406可以参考S201至S206，为了简洁，下面重点介绍该实施例中与S201至S206中不同的内容。
其中，网络设备向终端设备发送的所述配置信息包括多个第一信息与波束失败恢复请求消息的对应关系，即每个第一信息都有对应的波束失败恢复请求消息，并且多个第一信息对应同一个波束失败恢复请求消息，或者说，同一个波束失败恢复请求消息可以对应不同的第一信息。
其中，多个第一信息与波束失败恢复请求消息的对应关系，可以理解为：多个第一信息对应同一个第一资源，即多个第二资源对应同一个第一资源，即使用相同的第一资源发送波束失败恢复请求消息时，可以使用不同的第二资源发送上行信道。或者可以说，波束失败恢复请求消息与第一信息是对一多的对应关系。
这种情况下，S404中，终端设备根据所述配置信息中的所述对应关系，确定与所述波束失败恢复请求消息对应的第一信息时，可能会确定出多个与所述波束失败恢复请求消息对应的第一信息，此时，终端设备还需要从这多个第一信息中确定出目标第一信息，以根据该目标第一信息发送上行信道。
终端设备从这多个第一信息中确定出目标第一信息，可以包括：不同的第二波束对应不同的上行信道，或者说不同的第二波束对应不同的第二资源，或者说不同的第二波束对应不同的第一信息，然后终端设备根据确定的第二波束来从多个第一信息中的第二资源的信息；如果确定的第二波束为波束#2，则目标第一信息指示的第二资源用于发送波束#2对应的PUCCH#2。
或者，终端设备从这多个第一信息中确定出目标第一信息，可以包括：通过第一小区的标识来确定目标第一信息。例如不同的小区可以对应不同的第一信息，如果终端设备在Cell#1进行波束失败恢复，那么目标第一信息指示的第二资源用于发送与cell#1对应的PUCCH#1；如果终端设备在cell#2进行波束失败恢复，那么目标第一信息指示的第二资源用于发送与cell#1对应的PUCCH#1。
本申请另一个实施例的通信方法可以包括S501至S506。
应理解，在本申请实施例中，以终端设备和网络设备作为执行本申请实施例通信方法的执行主体为例，对本申请实施例的通信方法进行说明。作为示例而非限定，执行本申请 实施例的通信方法的执行主体也可以是应用于终端设备的芯片和应用于网络设备的芯片。
S501至S506可以参考S201至S206，为了简洁，下面重点介绍该实施例中与S201至S206中不同的内容。
其中，网络设备向终端设备发送的所述配置信息包括多个第一信息与多个波束失败恢复请求消息的对应关系，即同一个波束失败恢复请求消息可以对应不同的第一信息，且同一个第一信息可以对应不同的波束失败恢复请求消息。
其中，每个波束失败恢复请求消息可以对应多个第一信息，不同的波束失败恢复请求消息可以对应同一个第一信息。换句话说，配置信息中可以包括多个第一资源与多个第二资源的对应关系，每个第一资源可以对应不同的第二资源，不同的第一资源可以对应相同的第二资源。
这种情况下，终端设备根据所述配置信息中的所述对应关系，确定与所述第一波束失败恢复请求消息对应的第一信息的实现方式，可以参考S404，此处不再赘述
