为了保证业务的有效传输，小区会引入波束赋形(beam forming)技术，即基站通过把信号的能量集中于某一个需要的方向，通过该方向的波束向终端发送信号，从而提高终端的解调信噪比，改善小区边缘用户体验。当该终端的所有服务波束的质量不满足条件时，表示发生了波束失败现象，为了保证终端与基站之间的通信，需要进行波束失败恢复，即终端从候选波束中重新确定质量满足条件的候选波束，然后向基站发送波束失败恢复请求，通过该请求告知基站该终端选择的候选波束，以便基站将该候选波束作为该基站与终端通信的服务波束。目前，这种波束失败恢复方案应用于终端只有一个服务小区的场景。但是，当UE配置了载波聚合(carrier aggregation，CA)和/或双连接(dual connectivity，DC)时，即UE的服务小区为多个，此时UE如何向基站发送波束失败恢复请求是亟需解决的问题。

具体的，波束可以是指具有一定能量传输指向性的预编码向量并且能够通过标识信息去标识该预编码向量，所述能量传输指向性是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，而在其他空间位置内，接收经过该预编码向量进行预编码处理后的信号的功率较低，不满足接收解调信噪比。不同的通信设备可以有不同的预编码向量，即对应不同的波束，针对通信设备的配置或者能力，一个通信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。所述波束可以理解为空间资源。波束可以通过标识信息进行标识，可选地，所述标识信息可以对应配置该用户的对应的资源标识(identity，ID)，比如，所述标识信息可以对应配置的信道状态信息参考信号(Channel status information Reference Signal，CSI-RS)的ID或者资源；也可以是对应配置的上行探测参考信号(Sounding Reference Signal，SRS)的ID或者资源。或者，可选地，所述标识信息也可以是通过波束承载的信号或信道显示或隐式承载的标识信息，比如，所述标识信息包括但是不限于通过波束发送的同步信号或者广播信道指示该波束的标识信息，包括但是不限于通过该波束发送的同步信号块(Synchronization Signal block，SS block)指示该波束的标识信息(比如，SS block index)，其中SS block(SSB)至少包括主同步信号(PSS)和/或辅同步信号(SSS)和/或广播信道(PBCH)。
图2为本申请一实施例提供的通信方法的流程图，如图2所示，本实施例的方法可以包括：
S201、终端通过第一资源向网络设备发送第一请求。
相应地，网络设备通过第一资源从终端接收第一请求。
S202、网络设备向所述终端发送与该第一请求对应的第一响应。
相应地，终端从所述网络设备接收与该第一请求对应的第一响应。
本实施例中，第一小区为终端的服务小区，在终端的第一小区的波束失败后需要进行该第一小区的波束失败恢复的情况下，终端可以向网络设备发送第一请求，该第一请求用于请求第一小区的波束失败恢复；或者，在终端需要请求第一小区的系统信息的情况下，例如第一小区的系统信息更新，终端可以向网络设备发送第一请求，该第一请求用于请求第一小区的系统信息。
可选地，第一小区的波束失败可以基于第一小区的PDCCH质量确定，该PDCCH质量是基于CSI-RS或SSB获得。具体地，当终端连续N次确定第一小区的PDCCH质量低于预设的第一小区的PDCCH质量的门限，终端确定第一小区的波束失败。第一小区可以为至少一个小区，不同的小区对应的PDCCH的质量的门限是由网络设备单独配置的；不同的小区对应的N是由网络设备单独配置的，其中N为整数。其中，波束失败恢复请求过程是用于在基于SSB或CSI-RS确定波束失败后向网络设备指示新的SSB或者CSI-RS。
其中，服务小区为可用于为连接态的终端提供无线资源的小区；如果没有配置载波聚合(carrier aggregation，CA)和/或双连接(dual connectivity，DC)，则连接态的终端只有一个服务小区；如果连接态的终端配置了CA和/或DC，则服务小区为至少一个小区，包括主小区(Primary Cell，PCell)和辅小区(Secondary Cell，SCell)。PCell为工作在主频率，终端可以执行初始连接建立过程或发起连接重建立过程，或在切换过程被指示为主小区的小区。辅小区(Secondary Cell，SCell)，为工作在辅频率的小区，为连接态终端提供额外的无线资源。激活的服务小区为可用于数据传输的服务小区。主辅小区(Primary Secondary Cell，PSCell)为当辅基站的辅小区发生改变，可以发起基于竞争的随机接入的小区。PUCCH SCell为配置了PUCCH的SCell。本实施例中的第一小区例如为主小区(Pcell)，本实施例中的第二小区例如为辅小区(Scell)。
本实施例中，终端的服务小区为多个，例如配置了CA和/或DC的情况下，因此，本实施例终端通过第一资源向网络设备发送第一请求，该第一资源为不同于第一小区的一个服务小区的资源，本实施例将该不同于第一小区的一个服务小区称为第二小区，比如，第一小区为低频小区，第二小区为高频小区。
一种可能的方式中，本实施例可以应用于至少两个小区的组合场景，其中，该至少两个小区例如可以均为如下一类小区，或者，该至少两个小区可以包括如下至少两类小区，但本实篱例并不限于此。
第1类：高频上行和高频下行的小区，该小区的上行和下行均为高频。
第2类：高频下行和低频上行的小区，该小区的下行为高频，上行为低频。
第3类：单(高频或低频)下行的小区，该小区没有上行，且该小区的下行为高频或者上行。
第4类：单下行和多上行的小区，该上行有一个下行，而且具有多个上行。
在至少两个小区的组合场景中，如果一个为第一小区，其它小区为第二小区。该至少两个小区可通过载波聚合或双连接的方式为终端提供服务。
其中，所述第一资源包括以下至少一项：时域资源、频域资源、空域资源。其中，空域资源可以理解为波束(beam)。其中所述第一资源为专用的，可以在第二小区中唯一标识所述终端，即网络设备通过第一资源接收到该第一请求，根据该第一资源可以确定该第一请求该终端发送的。
网络设备通过第一资源从终端接收第一请求，然后根据该第一请求向终端发送与第一请求对应的第一响应，若第一请求用于请求第一小区的波束失败恢复，则终端接收到与该第一请求对应的第一响应，根据该第一响应可确定第一小区的波束失败恢复完成；若第一请求用于请求第一小区的系统信息，则终端接收到与该第一请求对应的第一响应，即可从第一响应中获得第一小区的系统信息，也就是说第一响应中包括第一小区的系统消息。
本实施例中，终端通过不同于第一小区的服务小区的资源向网络设备发送第一请求，该第一请求是有关第一小区的第一请求，用于请求第一小区的波束失败恢复或者请求第一小区的系统信息。因此，在终端的服务小区为多个时，终端可以跨小区(跨载波)传输请求，以提高传输的可靠性。
在一些实施例中，本实施例的方法还可以包括：
S203、网络设备向终端发送配置信息。
相应地，终端从网络设备接收配置信息。
可选的，网络设备可以在终端向网络设备发送第一请求之前，向终端发送配置信息，该配置信息包括第一资源的指示信息，当终端接收到该指示信息，获知可以通过第一资源发送上述第一请求。那么，终端从网络设备接收配置信息之后，在需要发送第一请求的情况下，根据上述配置信息，通过第一资源向网络设备发送第一请求。
本实施例中用于发送第一请求的第一资源是网络设备给终端配置的。需要说明的是，并不是终端每次通过第一资源发送第一请求之前均要从网络设备接收一次配置信息。
在一些实施例中，网络设备还向终端发送所述第一小区的至少一个波束的标识信息与所述第一资源中的部分或全部资源之间的关联关系，为了描述方便，将该关联关系称为第一关联关系，相应地，终端还从网络设备接收上述第一关联关系。可选地，上述第一关联关系包括在上述的配置信息中，也可以不包括在上述的配置信息中，该第一关联关系例如是用以表示波束的标识信息与资源的指示信息之间关联的表格，这表示第一小区的至少一个波束中每个波束的标识信息与第一资源中的部分资源或全部资源相关联，其中，每个波束的标识信息关联的第一资源中的资源(包括时域资源、频域资源、空域资源的至少一项)可能不完全相同。其中，本实施例中的波束的标识信息可以为：SSB的标识信息或CSI-RS的标识信息，该波束的标识信息可以标识该波束。其中，SSB包括以下至少一项：主同步信号(Primary synchronization signal，PSS)、辅同步信号(secondary synchronization signal，SSS)、物理广播信道(Physical broadcast channel，PBCH)。可选地，SSB的标识信息为SSB index，CSI-RS的标识信息为CSI-RS的资源ID。需说明的是所述至少一个波束的标识信息中的波束为下行波束。
需要说明的是，每个波束的标识信息关联的第一资源的部分资源或者全部资源，可以是，每个波束的标识信息关联一组资源，或者，多组资源；若第一波束的标识信息关联多组资源，则终端从该多组资源中选择一组资源用于发送第一请求。可选的，多个波束的标识信息可以关联同一组资源。
在一些实施例中，上述S201的一种可能的实现方式包括：终端根据所述第一小区的第一波束以及所述第一关联关系，通过所述第一资源向所述网络设备发送所述第一请求；所述第一波束为信号质量满足预设条件的所述第一小区的波束。即终端从第一小区的波束中确定信号质量满足预设条件(例如信号质量大于一门限值)的波束，为描述方便，此处称为第一波束，由于每个波束具有标识该波束的标识信息，因此，终端根据该第一波束的标识信息，以及上述的第一关联关系，确定该第一波束关联的第一资源中的部分资源或全部资源，然后通过确定的该第一资源中的部分资源或全部资源，向网络设备发送第一请求。需要说明的是，即使实际发送第一请求的资源为第一资源中的部分资源，也属于通过第一资源发送第一请求的保护范围。需要说明的是，本申请各实施例中涉及的第一波束为下行波束。
本申请实施例所描述的信号质量是指用于表征信号的质量的参数，例如可以是参考信号接收功率(reference signal received power，RSRP)，或者，参考信号接收质量(Reference Signal Receiving Quality，RSRQ)。
其中，若终端确定第一小区中信号质量满足预设条件的波束为多个时，则终端从信号质量满足预设条件的多个波束中选择一个波束为第一波束。
例如：每个波束可能关联的资源不完全相同，有些波束关联物理上行控制信道(Physical uplink Control channel，PUCCH)资源，有些波束关联基于非竞争的随机接入(contention free random access，CFRA)CSI-RS资源，有些波束关联CFRA SSB资源，有些波束关联基于竞争的随机接入(contention based random access，CBFA)SSB资源，关联的资源类型不同，波束的优先级存在差异，其中，波束 的优先级从高到低的顺序为：关联PUCCH资源的波束、关联CFRA CSI-RS资源的波束、关联CFRA SSB资源的波束、关联CBFA SSB资源的波束。在另一些实施例中，波束的优先级的顺序可以包括以上至少任意两种波束的优先级的顺序。
可选的，波束可以根据上述优先级的顺序，从信号质量满足预设条件的多个波束中确定优先级最高的波束为第一波束。
在一些实施例中，网络设备还向终端发送所述第一资源的部分资源或者全部资源与上行频带的标识信息之间的关联关系；为了描述方便，将该关联关系称为第二关联关系，相应地，终端从网络设备接收上述第二关联关系。可选地，上述第二关联关系包括在该配置信息中，也可以不包括在上述的配置信息中，第二关联关系例如是用以表示上行频带的标识信息与资源的指示信息之间关联的表格，这表示第一小区的上行频带与第一资源中的部分资源或全部资源相关联，其中，每个上行频带关联的第一资源中的资源可能不完全相同。例如第二小区具有多个上行频带时，因此需要确定采用哪个上行频带发送第一请求，本实施例中，每个上行频带具有相应的标识信息，用于标识该上行频带，该标识信息例如为上行频带的索引(index)。
在一些实施例中，上述S201中终端通过第一资源向网络设备发送第一请求的一种可能的实现方式包括：终端根据所述第一小区的第一波束、所述第一关联关系以及所述第二关联关系，通过所述第一资源向所述网络设备发送所述第一请求。其中，所述第一波束可以参见上述描述，此处不再赘述。由于每个波束具有标识该波束的标识信息，因此，终端根据该第一波束的标识信息，以及上述的第一关联关系，确定该第一波束关联的第一资源中的部分资源或全部资源；再根据第一波束关联的第一资源中的部分资源或全部资源，与第二关联关系，确定该部分资源或全部资源关联的上行频带的标识；然后根据该上行频带的标识，通过第一波束关联的该上行频带上的第一资源中的部分资源或全部资源向网络设备发送第一请求。
在一些实施例中，上述的第一请求可以是随机接入前导(preamble)，随机接入前导可以通过物理随机接入信道(Physical random access channel，PRACH)进行传输的。或者，上述的第一请求可以上行控制信息，上行控制信息可以通过物理上行控制信道(Physical uplink control channel，PUCCH)进行传输。可选地，当网络设备通过第一资源接收到随机接入前导或者上行控制信息，可以确定是该终端发送的，也可以确定是用于请求第一小区的波束失败恢复或者用于请求第一小区的系统信息。
在一些实施例中，网络设备还向终端发送所述第一小区的至少一个波束的标识信息与随机接入前导的关联关系，为了描述方案，此处的关联关系称为第三关联关系，相应地，终端从网络设备接收上述第三关联关系。可选地，上述第三关联关系包括在该配置信息中，也可以不包括在上述的配置信息中，第三关联关系例如是用以表示至少一波束的标识信息与随机接入前导之间关联的表格，这表示第一小区的波束与随机接入前导相关联。可选地，终端通过第一资源向网络设备发送第一请求的一种方式为：终端通过第一资源向网络设备发送随机接入前导，该随机接入前导根据上述第一波束以及上述第三关联关系确定。
在一些实施例中，上述S202中网络设备向终端发送第一响应的一种可能的实现方式可以包括：网络设备根据所述第一响应的发送参数，向所述终端发送所述第一响应。
可选地，可以根据接收所述第一请求的所述第一资源中的部分资源或全部资源与所述第一关联关系确定所述第一响应的发送参数。本实施例中，网络设备接收到第一请求后，可以确定该第一请求是通过哪些资源来接收的，例如第一资源中的部分或全部资源。由于存在上述第一关联关系，因此，根据接收第一请求的第一资源中的部分或全部资源，以及第一关联关系，确定与接收第一请求的第一资源中的部 分资源或全部资源所关联的第一波束。若第一请求用于请求第一小区的波束失败恢复，则网络设备可以将第一波束作为第一小区的服务波束。网络设备在确定第一波束之后，根据第一波束的发送参数确定第一响应的发送参数，然后根据该第一响应的发送参数，向终端发送第一响应。服务波束可以理解为该波束用于发送下行控制信息。
其中，发送参数包括以下至少一项：离开角(angle of Direction)、平均离开角(average(angle of Direction，AoD)、离开角的角功率谱(PAS of AoD)、传输和接收信道相关性(transmit/receive channel correlation)、传输和接收波束成型(transmit/receive beamforming)、空间信道相关性(spatial channel correlation)。
相应地，上述S202中终端从网络设备接收第一响应的一种可能的实现方式可以包括：终端根据所述第一响应的接收参数，从所述网络设备接收所述第一响应，所述第一响应的接收参数是根据所述第一波束的接收参数确定的。本实施例中，终端可以根据上述第一波束的接收参数确定第一响应的接收参数。例如：第一响应的接收参数与第一波束的接收参数相同。比如当终端接收传输第一响应的物理下行共享信道(Physical downlink shared channel，PDSCH)时，终端可以确定PDSCH的解调参数信号(demodulation reference signal，DMRS)的接收参数是根据所述第一波束的接收参数确定的。所述接收参数包括以下至少一项：平均增益(average gain)、平均时延(average delay)、时延扩展(delay spread)、多普勒偏移(Doppler shift)、多普勒扩展(Doppler spread)、到达角(angle of arrival，AoA)、平均到达角(average AoA)、显性到达角(Dominant AoA)、到达角的角功率谱(Power Angular Spectrum(PAS)of AoA)、平均离开角(average(angle of Direction，AoD))、离开角的角功率谱(PAS of AoD)、传输和接收信道相关性(transmit/receive channel correlation)、传输和接收波束成型(transmit/receive beamforming)、空间信道相关性(spatial channel correlation)。
在一些实施例中，若终端在发送第一请求后预设时长内未接收到网络设备发送的与第一请求对应的第一响应，则终端可以再次通过第一资源向网络设备发送第一请求。可选地，本实施例的终端还可以记录第一请求的发送次数，若第一请求的发送次数大于或等于预设次数，且终端仍未接收到与第一请求对应的第一响应，则终端可以认为第一小区的波束失败恢复失败或者请求第一小区的系统信息失败。
在一些实施例中，网络设备可以通过第一小区向终端发送与第一请求对应的第一响应。相应地，终端通过第一小区从网络设备接收与第一请求对应的第一响应。在一些实施例中，上述的第一响应为小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)加扰的物理下行控制信道(Physical downlink control channel，PDCCH)，或者，所述第一响应为随机接入响应。本实施例中，终端接收到C-RNTI加扰的PDCCH或者随机接入响应，判断该C-RNTI加扰的PDCCH或者随机接入响应是否通过第一小区接收的，若是通过第一小区的接收的，则终端确定该C-RNTI加扰的PDCCH或者随机接入响应为与上述第一请求对应的第一响应，否则表示终端未接收到与第一请求对应的第一响应。
在一种可能的实现方式中，第一响应为C-RNTI加扰(该C-RNTI用于标识该终端)的PDCCH。其中，C-RNTI加扰的PDCCH可以理解为通过PDCCH发送的下行控制信息(downlink control information，DCI)的循环冗余校验(cyclic redundancy check，CRC)是用C-RNTI进行加扰的。CRC可以用于判断该DCI的信息比特是否被解码成功。该DCI可以为下行分配(downlink assignment)或上行授权(uplink grant)。下行分配用于分配下行资源，uplink grant用于分配上行资源。例如：终端使用第一响应的接收参数从网络设备配置的用于接收响应消息的专用控制资源集合(Control Resource Set，CORESET)接收DCI，则终端可以确定波束失败恢复过程完成。该专用CORESET可用于传输专用的下行控制信息，具体的，传输C-RNTI加扰的DCI；其中，该专用CORESET例如可以包括以下至少一项：频域资源， 开始符号、时长、周期，交错指示，DMRS加扰ID。可选地，所述用于接收第一响应的专用控制资源集合与所述第一波束的标识信息有关联。在另一些实施例中，针对这种实现方式中的有关第一响应的描述，对应的第一请求可以是终端通过第一小区向网络设备发送的。
在另一种可能的实现方式中，第一请求为基于非竞争的随机接入前导，相应地，第一响应为随机接入响应。在基于非竞争的随机接入过程中，所述随机接入响应只包括字头，该字头中有随机接入前导标识的字段。若终端通过相应的随机接入临时标识(random access cell radio network temporary identifier，RA-RNTI)接收到携带所述随机接入前导(即第一请求)标识的随机接入响应，则终端确定随机接入完成，并确定第一小区的波束失败恢复过程完成。
在另一种可能的实现方式中，第一请求为基于竞争的随机接入前导(Msg1)。在基于竞争的随机接入过程中，与随机接入前导对应的随机接入响应消息包括字头，该字头中有随机接入前导标识的字段，还包括上行授权，可选地，随机接入响应消息还可以包括时间提前量指示，临时(temporary)C-RNTI。终端接收到网络设备发送的随机接入响应(Msg2)。若第一请求用于请求第一小区的波束失败恢复，则终端还根据所述随机接入响应，通过第二小区向网络设备发送第一数据(如Msg3)，所述第一数据包括上述C-RNTI，终端再通过第一小区从网络设备接收第二数据(如Msg4)，第二数据是C-RNTI加扰的PDCCH，可以是Downlink assignment或uplink grant；该第二数据用于竞争解决；终端在接收到上述的第二数据后，可以确定随机接入完成，并确定第一小区的波束失败恢复过程完成，不再向网络设备发送第一请求。若第一请求用于请求第一小区的系统信息，则终端根据所述随机接入响应，通过第一小区向网络设备发送第一数据(如Msg3)，所述第一数据包括上述C-RNTI和请求的系统信息类型，终端再通过第一小区接收第二数据，第二数据是C-RNTI加扰的PDCCH，可以是下行分配(Downlink assignment)或上行授权(uplink grant)；第二数据用于竞争解决；终端在接收到随机接入响应并接收到上述的第二数据后，可以确定随机接入完成，并获得第一小区的系统信息。
在一些实施例中，网络设备通过不同于第一小区的终端的服务小区，向终端发送所述第一响应。相应地，终端通过不同于第一小区的服务小区从网络设备接收第一响应，所述第一响应包括第一小区的标识信息，本实施例的终端可以根据第一响应中的第一小区的标识信息，确定该第一响应为与第一请求对应的第一响应，从而确定第一小区的波束失败恢复过程完成或者确定获得第一小区的系统信息。其中，该第一小区的标识信息可以承载于DCI的预留字段中，通过该预留字段的比特用于指示第一小区的标识信息，例如：“00”对应cell1，“01”对应cell2；这个对应关系可以由网络设备配置或协议预先规定。
可选地，针对第一请求为随机接入前导的方案中，针对配置CA的场景，则通过PCell的随机接入的优先级比SCell的高。针对配置DC的场景，则通过主小区group的PCell的随机接入的优先级比通过主小区group的SCell的随机接入的优先级高；通过辅小区group的PSCell的随机接入的优先级比通过辅小区group的SCell的随机接入的优先级高。如果通过SCell触发随机接入(比如需要波束失败恢复或者需要请求系统信息)，同时通过PCell也触发随机接入(比如，由于上行数据到达，但是上行失步或由于下行数据到达，但是上行失步)，则终端执行通过PCell触发的随机接入。如果终端正在通过PCell进行随机接入，通过SCell触发随机接入，则终端继续通过PCell进行的随机接入。如果终端正在进行通过SCell的随机接入，通过PCell触发随机接入，则终端停止通过SCell的随机接入，开始通过PCell的随机接入。
其中，上述的配置信息例如可以是无线资源控制(Radio Resource Control，RRC)消息。

本实施例中，当终端的第一小区的波束失败后需要进行该第一小区的波束失败恢复的情况下，终端可以向网络设备请求第一小区的波束失败恢复；或者，在终端需要请求第一小区的系统信息的情况下，例如第一小区的系统信息更新，终端可以向网络设备请求第一小区的系统信息。本实施例中，终端通过第二小区发起随机接入来向网络设备请求，其中，该随机接入为基于竞争的随机接入。需要说明的是，前述实施例中的有关第一小区和第二小区的说明同样适用于本实施例，此处不再赘述。
可选地，本实施例的终端还从网络设备接收随机接入的配置信息，该随机接入的配置信息用于随机接入过程。

S303、终端根据随机接入响应，通过第二小区向网络设备发送第一数据。
相应地，网络设备通过第二小区从终端接收第一数据。
本实施例中，终端接收到随机接入响应之后，通过第二小区向网络设备发送第一数据(如Msg3)，该第一数据中包括：该终端的C-RNTI(即该C-RNTI可以不同于上述temporary C-RNTI)。由于本实施例中终端请求第一小区的波束失败恢复或者请求第一小区的系统信息，因此该第一数据还包括：第一波束的标识信息。该第一波束为第一小区中信号质量满足预设条件的波束，其中，第一波束的相关描述可以参见上述实施例中的相关描述，此处不再赘述。其中，该第一波束的标识信息可以是SSB的标识信息和/或CSI-RS的标识信息，SSB的标识信息比如为第一小区的标识信息和SS block index，CSI-RS的标识信息比如为第一小区的标识信息和CSI-RS ID。可选的，第一数据可以通过MAC CE的方式进行传输，MAC CE的第一字段用于指示是否存在第一小区的第一波束的标识信息，第二字段用于指示第一小区的波束的标识信息(例如第一小区的SSB的标识信息和/或第一小区的CSI-RS的标识信息)，其中，第一字段为预留字段，比如，第一字段的比特位为“1”，表示存在第二字段，第一字段的比特位为“0”，表示不存在第二字段。其中，CSI-RS ID用于标识至少一份CSI-RS资源。SS block索引用于标识SS block。其中，该第一波束的标识用于波束失败恢复。需要说明的是，CSI-RS ID可以为CSI-RS配置ID或CSI-RS resource ID，用于标识一组配置，该配置至少包括一组CSI-RS资源。需说明的是，第一小区可以为至少一个发生波束失败的小区。
S304、网络设备通过第一小区或第二小区向终端发送第二数据。
相应地，终端通过第一小区或者第二小区从网络设备接收第二数据。
本实施例中，网络设备接收到第一数据，根据第一数据中的第一波束的标识，确定终端请求波束失败恢复，即将第一波束作为服务波束，网络设备通过第一小区或第二小区向终端发送第二数据(如Msg4)，该第二数据是C-RNTI加扰的PDCCH。终端在发送完第一数据后，通过第一小区或第二小区接收到该C-RNTI加扰的PDCCH后，确定第一小区的波束失败恢复过程完成或者获得第一小区的系统信息。可选地，终端还根据第二数据确定随机接入完成，第二数据用于竞争解决。
可选的，网络设备根据第一波束(该波束对应的SS block和/或CSI-RS)，确定第一小区的PDCCH的发送参数，然后根据该PDCCH的发送参数，通过第一小区向终端发送上述第二数据。
可选的，终端根据第一波束的接收参数通过第一小区从网络设备接收上述第二数据(例如该C-RNTI加扰的PDCCH)，或者，终端根据第一波束的接收参数通过第一小区的专用CORESET从网络设备接收第二数据(例如该C-RNTI加扰的PDCCH)，该专用CORESET用于传输专用的下行控制信息(具体的可以为用于传输C-RNTI加扰的DCI)。例如：第二数据的接收参数与第一波束的接收参数相同。其中，有关接收参数的描述可以参见上述实施例中的相关描述，此处不再赘述。
可选的，网络设备根据与接收所述随机接入前导的资源对应的第二小区的下行波束(该波束对应的SS block和/或CSI-RS)的发送参数，确定第二小区的PDCCH的发送参数，然后根据该PDCCH的发送参数，通过第二小区向终端发送上述第二数据。
可选的，终端根据与发送所述随机接入前导的资源对应的下行波束的接收参数通过第二小区从网络设备接收上述第二数据，例如：第二数据的接收参数与发送所述随机接入前导的资源对应的下行波束的接收参数相同。其中，有关接收参数的描述可以参见上述实施例中的相关描述，此处不再赘述。
本实施例中，在第一小区的波束失败的情况下，终端通过第二小区向网络设备发送随机接入前导，然后通过第二小区从网络设备接收随机接入响应，再根据随机接入响应，向网络设备发送Msg3，该Msg3包括第一小区的波束的标识，以请求波束失败恢复，或者请求第一小区的系统信息。本实施例是通过跨小区(跨载波)传输基于竞争的随机接入来请求波束失败恢复或者请求第一小区的系统信息，可提高传输的可靠性。
可选地，上述图2对应的实施例与上述图3对应的实施例可以相互独立，也可以存在一定的关联。例如：终端在确定第一小区发生波束失败后可以先判断上述的第一波束是否有对应的PUCCH资源和/或基于非竞争的随机接入资源，即是否有用于发送第一请求(上行控制信息)的PUCCH资源或者用于发送第一请求(非竞争的随机接入前导)CFRA资源，如果有PUCCH资源或者CFRA资源，可以用PUCCH资源或者CFRA资源发送第一请求，执行上述图2对应的实施例。如果没有PUCCH资源和CFRA资源，若存在PUSCH资源，那么终端生成一个媒体接入控制控制元素(medium access control control element，MAC CE)MAC CE，用于指示第一小区的第一波束的标识信息，MAC CE相当于图3所示实施例中第一请求的作用，网络设备接收到MAC CE后向终端发送确认响应，通知终端基于第一波束的接收参数从网络设备接收DCI；若不存在PUSCH资源，则执行图3对应的实施例。
图4为本申请另一实施例提供的通信方法的流程图，如图4所示，本实施例的方法可以包括：
S401、终端向网络设备发送第一请求。
相应地，网络设备从终端接收第一请求。
本实施例中可以应用于终端的服务小区为多个的场景，例如：第一小区和至少一个第二小区，其中，第一小区为具有SSB或CSI-RS的小区，第二小区为不具有SSB或CSI-RS的小区。其中，第二小区的同步是基于第一小区的SSB或CSI-RS。需要说明的是，本实施例的应用场景并不限于此。

在一些实施例中，网络设备根据上述的PDCCH的发送参数，向终端发送DCI，相应地，终端根据上述确定的PDCCH的接收参数，从网络设备接收DCI。
在一种可能的实现方式中，第一响应包括第二小区的至少一个PDCCH的标识信息，比如PDCCH的DMRS端口的标识信息或者PDCCH的DMRS的标识信息。可选地，网络设备根据该第一波束的发送参数，确定至少一个PDCCH的发送参数，该第一响应包括的是该网络设备确定发送参数的该至少一个PDCCH的标识信息，或者，该第一响应包括至少一个PDCCH的标识信息，网络设备根据第一波束的发送参数，确定所述至少一个标识信息标识的至少一个PDCCH的发送参数。终端根据第一响应中的所述至少一个标识信息以及第一波束的接收参数，确定所述至少一个标识信息所标识的至少一个PDCCH的接收参数。需要说明的是，第一响应中可以包括第二小区的部分PDCCH的标识信息，或者，第一响应中可以包括第二小区的全部PDCCH的标识信息。

图5为本申请另一实施例提供的通信方法的流程图，如图5所示，本实施例的方法可以包括：

可选的，PDCCH的接收参数可以包括PDCCH的DMRS接收参数。
在一些实施例中，网络设备在向终端发送第一指示之前，确定第一小区的至少一个PDCCH的发送参数。
在一些实施例中，上述第一指示包括所述第一小区的至少一个PDCCH的标识信息(例如PDCCH的DMRS端口的标识信息，或者，PDCCH的DMRS的标识信息)和第二小区的波束的标识信息；相应地，终端根据所述第一指示以及所述第二小区的波束的接收参数，确定所述第一小区的至少一个PDCCH的接收参数。本实施例中，终端根据第一指示中的第二小区的波束的标识信息，确定第二小区的该波束的接收参数，然后根据该波束的接收参数，确定该至少一个PDCCH的标识信息所标识的至少一个PDCCH的接收参数。另外，网络设备根据第二小区的波束的发送参数，确定该至少一个PDCCH的标识信息所标识的至少一个PDCCH的发送参数。在网络设备确定上述发送参数以及终端确定上述接收参数之后，网络设备通过该第一小区向终端发送下行控制信息，相应地，终端通过该第一小区从网络设备接收下行控制信息。该下行控制信息为下行分配(downlink assignment)或上行授权(uplink grant)。
其中，DMRS端口的标识信息例如包括：第一小区的cell index和DMRS端口索引/标识。第二小区的波束的标识信息例如包括：第二小区的cell index和波束(如SS block)index。
本实施例中通过上述方案，在小区不具有SSB或CSI-RS时，也可以确定该小区的PDCCH的接收参数(例如PDCCH的DMRS接收参数)。
在本申请另一实施例提供的通信方法中，包括如下步骤：
步骤A、终端的L1(即物理层)在检测到服务小区的波束失败发生后向终端的L2(媒体接入控制层)发送该服务小区的波束失败指示。
步骤B、终端的L2接收到波束失败指示启动第一定时器，可选地，还启动第二定时器，第一定时器和第二定时器任意一个定时器超时则退出波束失败恢复(beam failure recovery，BFR)过程并向L3(RRC层)指示BFR失败。如果当前发生BFR失败的该服务小区是Scell，则终端向网络设备发送BFR失败报告，以用于去激活该SCell。其中，第一定时器用于控制beam failure recovery过程的时长，第二定时器用于控制候选波束(candidate beam)的监视时间。
步骤C、[可选的，在第二定时器运行期间]，终端识别候选波束(该波束为下行波束，可能关联用于发送波束失败请求的PUCCH资源、基于竞争的随机接入资源、基于非竞争的随机接入资源，直到识别到(RSRP>＝门限)的至少一个候选波束。终端从至少一个候选波束中选择一个波束(称为第一波束)，以用于发送波束恢复请求(beam failure recovery request，BFRQ)。可选地，每个波束可能关联的资源不完全相同，有些波束关联PUCCH(Physical uplink Control channel，物理上行控制信道)资源，有些波束关联CFRA(contention free random access，基于非竞争的随机接入)CSI-RS资源，有些波束关联CFRA SSB资源，有些波束关联CBFA(contention based random access，基于竞争的随机接入)SSB资源，关联的资源类型不同，波束的优先级存在差异，终端设备根据预设优先级，确定一个beam，波束的优先级从高到低的顺序为：关联PUCCH资源的波束、关联CFRA CSI-RS资源的波束、关联CFRA SSB资源的波束、关联CBFA SSB资源的波束；因此，波束可以根据上述优先级的顺序，至少一个候 选波束中确定优先级最高的波束为用于发送波束失败恢复请求。需说明的是，波束的优先级的顺序只要包括任意两个如上所述波束的优先级的顺序均可，若波束的优先级从高到低的顺序包括两种波束的优先级的顺序，例如为从高到低的顺序为：关联PUCCH资源的波束、关联CFRA SSB资源的波束；本实施例不做限定。
在选择波束之后，终端判断选择的波束是否存在有效的PUCCH资源用于BFRQ传输，若存在有效的PUCCH资源用于BFRQ传输，则使用该PUCCH资源发送PUCCH的BFRQ并进行PUCCH的BFRQ发送次数计数加一，在预设时长内监听C-RNTI加扰的PDCCH；若不存在有效的PUCCH资源用于BFRQ传输，则进一步判断该选择的波束是否配置有CFRA资源用于CFRA的BFRQ传输，若配置有CFRA资源，则使用该CFRA资源发送CFRA的BFRQ并进行CFRA的BFRQ发送次数加1，在预设时长内监听C-RNTI加扰的PDCCH，若未配置有CFRA资源，则判断此时是否存在PUSCH资源，如果存在PUSCH资源，生成MAC CE或物理层信令，向网络设备指示第一波束的标识信息，用于波束失败恢复，停止向网络设备发送PUCCH或CFRA或CBRA的BFRQ，如果不存在PUSCH资源，则使用CBRA资源发送CBRA的BFRQ并进行CBRA的BFRQ发送次数加1，继续进行之后的基于基站的随机接入过程。
如果终端的L1在预设时长内监听到C-RNTI加扰的PDCCH，则指示L2退出BFR过程；否则判断是否达到BFRQ发送最大次数，是则退出BFR过程并向L3指示BFR失败。
可以理解的是，上述各个实施例中，由终端实现的方法或步骤，也可以是由可用于终端的芯片实现的。由网络设备实现的方法或步骤，也可以是由可用于网络设备的芯片实现的。
