图2是根据一示例性实施例示出的一种随机接入指示方法的流程图。该方法可应用于图1所示的网络架构中。该方法可以包括如下几个步骤(201～202)。
在步骤201中，服务基站发送随机接入指示信令，该随机接入指示信令向终端指示用于发送随机接入前导码的目标天线面板和/或目标波束。
服务基站向终端发送随机接入指示信令，相应地，终端接收该服务基站发送的随机接入指示信令。服务基站是指终端所接入的服务小区所属的基站。
如果终端只接入了一个服务小区，则服务基站即为该服务小区所属的基站。如果终端同时接入了多个服务小区，如终端接入了一个PCell(Primary cell，主小区)，还接入了一个或多个SCell(Secondary Cell，辅小区)，在这种情况下，如果PCell和SCell共用同一个基站，则服务基站即为该共用的基站，如果PCell和SCell并不共用同一个基站，也即存在双连接，即有PeNB和SeNB，则服务基站有可能是PCell所属的基站，也有可能是PScell(Primary Secondary Cell，主辅小区)所属的基站。
在本公开实施例中，终端具有至少两个天线面板，且每个天线面板包括至少一个波束。服务基站通过随机接入指示信令，来向终端指示用于发送随机接入前导码的目标天线面板和/或目标波束。目标天线面板可以是一个天线面板，也可以是多个天线面板。目标波束可以是一个波束，也可以是多个波束。如果目标波束为多个波束，则该多个波束可以属于同一天线面板，也可以属于多个不同的天线面板。如果随机接入指示信令同时包含多个目标天线面板和多个目标波束时，需要指示清楚每个目标波束对应的目标天线面板。
可选地，随机接入指示信令中包括目标天线面板和/或目标波束的指示信息，该指示信息用于对目标天线面板和/或目标波束起到表征作用。
在一个示例中，该指示信息包括目标天线面板的标识和/或目标波束的标识。也即，随机接入指示信令中包括目标天线面板的标识和/或目标波束的标识。目标天线面板的标识用于唯一指示该目标天线面板，不同的天线面板具有不同的标识。天线面板的标识可以记为panel ID，其可以是一个由数字、字母、字符中 的至少一项所组成的字符串。目标波束的标识用于唯一指示该目标波束，不同的波束具有不同的标识。波束的标识可以记为beam ID，其可以是一个由数字、字母、字符中的至少一项所组成的字符串。例如，随机接入指示信令中包括panel#1和beam#5，从而向终端指示用于发送随机接入前导码的目标天线面板是编号为1的天线面板，用于发送随机接入前导码的目标波束是编号为5的波束。
在另一个示例中，该指示信息包括目标天线面板的标识和/或第二参考信号标识。也即，随机接入指示信令中包括目标天线面板的标识和/或第二参考信号标识。第二参考信号标识用于指示目标波束。终端根据该第二参考信号标识，能够确定出用于发送随机接入前导码的目标波束。第二参考信号标识是第二参考信号的标识，该第二参考信号可以是上行参考信号，比如SRS(Sounding Reference Signal，探测参考信号)，也可以是下行参考信号，比如SSB(Synchronization Signal Block，同步信号块)或CSI-RS(Channel State Information-Reference Signal，信道状态信息参考信号)。如果第二参考信号是上行参考信号，服务基站是告诉终端：使用发送该上行参考信号的发送波束，作为用于发送随机接入前导码的目标波束。如果第二参考信号是下行参考信号，服务基站是告诉终端：使用与接收该下行参考信号的接收波束相对应的发送波束，作为用于发送随机接入前导码的目标波束。例如，随机接入指示信令中包括panel#1和SRS#1，从而向终端指示用于发送随机接入前导码的目标天线面板是编号为1的天线面板，用于发送随机接入前导码的目标波束是发送该SRS#1的发送波束。再例如，随机接入指示信令中包括panel#1和SSB#1，从而向终端指示用于发送随机接入前导码的目标天线面板是编号为1的天线面板，用于发送随机接入前导码的目标波束是与接收该SSB#1的接收波束相对应的发送波束。
在另一个示例中，该指示信息包括第二参考信号组(组为group或set)标识和/或第二参考信号标识。也即，随机接入指示信令中包括第二参考信号组标识和/或第二参考信号标识。第二参考信号组标识用于指示目标天线面板，第二参考信号标识用于指示目标波束。终端根据该第二参考信号组标识，能够确定出用于发送随机接入前导码的目标天线面板。第二参考信号组标识是第二参考信号组的标识，第二参考信号组可以包括至少一个参考信号。终端根据该第二参考信号标识，能够确定出用于发送随机接入前导码的目标波束。第二参考信号标识是第二参考信号的标识。这里的参考信号同样可以是上行参考信号或下 行参考信号。
在另一个示例中，该指示信息包括第二参考信号标识。也即，随机接入指示信令中包括第二参考信号标识。第二参考信号标识用于指示目标天线面板和/或目标波束。终端根据该第二参考信号标识，能够确定出用于发送随机接入前导码的目标天线面板和/或目标波束。第二参考信号标识是第二参考信号的标识。这种情况下，如果每个天线面板上的参考信号的标识不一样，那么通过第二参考信号标识，就可以确定出用于发送随机接入前导码的目标天线面板和目标波束。
在步骤202中，终端根据随机接入指示信令，确定用于发送随机接入前导码的目标天线面板和/或目标波束。
终端在接收到随机接入指示信令之后，便可以据此确定出用于发送随机接入前导码的目标天线面板和/或目标波束，然后采用该目标天线面板和/或目标波束发送随机接入前导码，从而向网络侧发起随机接入。
可选地，如果随机接入指示信令仅指示了目标天线面板，则终端采用该目标天线面板发送随机接入前导码。在这种情况下，如果目标天线面板仅包括一个波束，则终端采用该波束发送随机接入前导码；如果目标天线面板包括多个波束，则终端可以从该多个波束中选择至少一个波束来发送随机接入前导码。
可选地，如果随机接入指示信令仅指示了目标波束，终端可以根据天线面板与波束之间的映射关系，确定出该目标波束所属的目标天线面板，这样也就确定出了用于发送随机接入前导码的目标天线面板和目标波束。
可选地，如果随机接入指示信令指示了目标天线面板和目标波束，则终端可以直接据此确定出用于发送随机接入前导码的目标天线面板和目标波束。
例如，随机接入指示信令中包括panel#0，则终端采用该编号为0的天线面板发送随机接入前导码，进一步可以采用该编号为0的天线面板上的至少一个波束发送随机接入前导码。再例如，随机接入指示信令中包括beam#1，假设beam#1属于panel#1，则终端采用该编号为1的天线面板上的、编号为1的波束发送随机接入前导码。再例如，随机接入指示信令中包括panel#1和beam#1，则终端采用该编号为1的天线面板上的、编号为1的波束发送随机接入前导码。
可选地，随机接入指示信令中还包括目标小区的标识，该目标小区是指终端所要发起随机接入的小区。目标小区的标识用于唯一指示该目标小区，不同的小区具有不同的标识。小区的标识可以记为cell ID，其可以是一个由数字、 字母、字符中的至少一项所组成的字符串。终端在获取到目标小区的标识之后，便可以获知向哪个小区发起随机接入。
可选地，随机接入指示信令中还包括终端在发送随机接入前导码后，用于监听RAR(Random Access Response，随机接入反馈)的天线面板和/或波束的指示信息。此处用于监听RAR的天线面板和/或波束的指示信息的实现形式，可以与上文介绍的目标天线面板和/或目标波束的指示信息的实现形式相同。例如，用于监听RAR的天线面板，可以采用天线面板的标识来指示，也可以采用参考信号组标识来指示，还可以采用参考信号标识来指示；用于监听RAR的波束，可以采用波束的标识来指示，也可以采用参考信号标识来指示。这里的参考信号同样可以是上行参考信号或下行参考信号。这样，终端就可以在发送随机接入前导码后，使用正确的天线面板和波束来监听网络侧反馈的RAR，提高随机接入效率。
综上所述，本公开实施例提供的技术方案中，通过服务基站向终端发送随机接入指示信令，使得终端能够据此确定出用于发送随机接入前导码的目标天线面板和/或目标波束；这样，当终端有多个天线面板时，终端能够准确确定出使用哪个天线面板发起随机接入，有助于提高随机接入的准确性和成功率，减少随机接入时延。
对于终端有多个天线面板的情况，终端发起随机接入的场景包括如下：
(1)终端的所有天线面板都切换至目标小区，选择其中一个或多个天线面板向目标小区发送随机接入前导码；
(2)终端的所有天线面板中，一个或多个特定的天线面板切换至目标小区，从该一个或多个特定的天线面板中，选择一个或多个天线面板向目标小区发送随机接入前导码，这里的目标小区是终端即将要切换过去的小区；
(3)终端发现服务小区的某个天线面板发生无线链路失败(Radio Link Failure)或波束失败(Beam Failure)，使用终端的目标天线面板向目标小区发送随机接入前导码，这里的目标小区其实是服务小区；此时，目标天线面板是指终端接收该发生无线链路失败或波束失败的基站天线面板发送的下行信息(如下行参考信号和/或下行控制信令)时，所使用的天线面板；
(4)终端接入到某个PCell后，需要添加SCell时，从终端的天线面板中选择一个或多个天线面板向目标小区发送随机接入前导码，这里的目标小区是 将要添加的SCell。
下面，针对上述几种不同场景，对相应的随机接入指示方法进行介绍说明。
对于场景(1)，随机接入指示信令为切换指令，该切换指令用于向终端指示切换至目标小区。可选地，切换指令包括目标小区的标识，切换指令还包括目标天线面板和/或目标波束的指示信息。据此，终端可以确定使用目标天线面板和/或目标波束发送随机接入前导码，实现向目标小区发起随机接入。
如图3所示，对于场景(1)，本公开实施例提供的随机接入指示方法可以包括如下几个步骤(301～306)：
在步骤301中，终端向服务基站发送RRM测量报告，该RRM测量报告包括至少一个邻小区的测量报告。
当终端对邻小区和服务小区进行测量，发现邻小区的测量值满足一定的测量报告触发事件时，比如Event A3：邻小区测量值比服务小区测量值大一个偏移量(offset)时，终端可以向服务基站发送RRM测量报告；相应地，服务基站接收终端发送的RRM测量报告。RRM测量报告用于上报服务小区和/或邻小区的无线信号质量。
RRM测量报告中包括至少一个邻小区的测量报告。邻小区的测量报告用于指示邻小区的无线信号质量。邻小区的测量报告可以包括：邻小区的标识、邻小区的测量值和测量对象信息。
邻小区的测量值用于指示该邻小区的无线信号质量。示例性地，测量值包括但不限于以下至少一种：RSRP(Reference Signal Received Power，参考信号接收功率)、RSRQ(Reference Signal Received Quality，参考信号接收质量)、SINR(Signal to Interference plus Noise Ratio，信号干扰噪声比)。RSRP包括L1-RSRP和/或L3-RSRP，RSRQ包括L1-RSRQ和/或L3-RSRQ，SINR包括L1-SINR和/或L3-SINR。L1(Layer 1，层一)是指物理层的瞬时抽样值，L3(Layer 3，层三)是指RRM层的滑动窗口内的平均值，如加权平均值。
测量对象信息用于指示终端测量得到邻小区的测量值时使用的接收天线面板和/或接收波束。终端在对邻小区进行信号测量时，可能使用各个接收天线面板的各个接收波束，而只有在使用上述测量对象信息中给出的接收天线面板和/或接收波束时，其测量值最大或满足某个条件(比如超过预设的门限值)，所以测量对象信息给出的接收天线面板和/或接收波束，是终端得到测量报告中给出 的邻小区的测量值时所使用的接收天线面板和/或接收波束，通过该接收天线面板和/或接收波束接收邻小区下发的下行参考信号，然后获取该下行参考信号对应的测量值。
在一个示例中，测量对象信息包括：接收天线面板的标识和/或接收波束的标识。例如，测量对象信息包括panel#0和beam#3，表示终端对邻小区进行信号测量时使用的接收天线面板是编号为0的天线面板，终端对邻小区进行信号测量时使用的接收波束是编号为3的波束。
在另一个示例中，测量对象信息包括：接收天线面板的标识和/或第一参考信号标识。第一参考信号标识用于指示接收波束。服务基站根据该第一参考信号标识，能够确定出终端进行信号测量时使用的接收波束。第一参考信号标识是第一参考信号的标识，该第一参考信号可以是下行参考信号，比如SSB或CSI-RS，也可以是上行参考信号，比如SRS。如果第一参考信号是下行参考信号，终端是告诉服务基站：终端使用的是接收这个下行参考信号的接收波束来测量的；如果第一参考信号是上行参考信号，终端是告诉服务基站：终端使用的是与发送该上行参考信号的发送波束相对应的接收波束来测量的。例如，测量对象信息包括panel#0和SSB#1，表示终端对邻小区进行信号测量时使用的接收天线面板是编号为0的天线面板，终端对邻小区进行信号测量时使用的接收波束是接收该SSB#1的波束。再例如，测量对象信息包括panel#0和SRS#1，表示终端对邻小区进行信号测量时使用的接收天线面板是编号为0的天线面板，终端对邻小区进行信号测量时使用的接收波束是与发送该SRS#1的发送波束相对应的接收波束。
在另一个示例中，测量对象信息包括：第一参考信号组(组为group或set)标识和/或第一参考信号标识。第一参考信号组标识用于指示接收天线面板，第一参考信号标识用于指示接收波束。服务基站根据该第一参考信号组标识，能够确定出终端进行信号测量时使用的接收天线面板。第一参考信号组标识是第一参考信号组的标识，第一参考信号组可以包括至少一个参考信号。服务基站根据该第一参考信号标识，能够确定出终端进行信号测量时使用的接收波束。第一参考信号标识是第一参考信号的标识。这里的参考信号同样可以是下行参考信号或上行参考信号。
在另一个示例中，测量对象信息包括：第一参考信号标识，该第一参考信号的标识用于指示接收天线面板和/或接收波束。服务基站根据该第一参考信号 标识，能够确定出终端进行信号测量时使用的接收天线面板和/或接收波束。第一参考信号标识是第一参考信号的标识。这种情况下，如果每个天线面板上的参考信号的标识不一样，那么通过第一参考信号标识，就可以确定出接收天线面板和接收波束。
示例性地，假设某个邻小区的测量报告包括：Cell ID#1，panel#0，beam#3，RSRP，则表示终端针对编号为1的邻小区，使用接收天线面板panel#0和接收波束beam#3对该邻小区下发的下行参考信号进行测量，获取的测量值是RSRP，该测量值可以用一个具体的数值表示，来体现该邻小区的无线信号质量。
需要说明的是，RRM测量报告中可以包括一个或多个邻小区的测量报告，但这些邻小区的测量结果需要满足一定条件，比如邻小区的测量值大于一个阈值，或邻小区的测量值与服务小区的测量值相比较，大于一个偏移量(offset)等。换句话说，如果某一邻小区的测量结果不满足上述条件，那么RRM测量报告中不携带该邻小区的测量报告，如果没有邻小区满足上述条件，终端是不会发送RRM测量报告的。
可选地，RRM测量报告中还包括服务小区的测量报告，服务小区的测量报告用于指示服务小区的无线信号质量。服务小区的测量报告的内容可以与邻小区的测量报告的内容相类似，此处不再赘述。
在步骤302中，服务基站从至少一个邻小区中选择目标小区。
可选地，服务基站根据各个邻小区的测量值，选择无线信号强度最优的一个邻小区作为目标小区。
在步骤303中，服务基站向目标小区所属的目标基站发送切换请求信令。
切换请求信令用于请求切换至目标小区。可选地，切换请求信令中包括目标小区的测量报告，如包括该目标小区的标识、目标小区的测量值和测量对象信息等内容。
目标基站在接收到切换请求信令之后，如果同意终端切换至目标小区，则向服务基站发送切换响应信令。
在步骤304中，服务基站接收目标基站发送的切换响应信令。
可选地，切换响应信令中包括目标天线面板和/或目标波束的指示信息。也即，目标基站确定出终端在向其发起随机接入时，用于发送随机接入前导码的目标天线面板和/或目标波束，并将该信息携带在切换响应信令中告知给服务基站，再由服务基站告知给终端。
目标天线面板和/或目标波束的指示信息用于对目标天线面板和/或目标波束起到表征作用。在图2实施例中已经介绍，该指示信息可以有多种实现形式，该指示信息可以包括目标天线面板的标识和/或目标波束的标识，或者包括目标天线面板的标识和/或第二参考信号标识，或者包括第二参考信号组标识和/或第二参考信号标识，或者包括第二参考信号标识。切换响应信令中具体包括何种形式的指示信息，取决于终端发送的测量报告中测量对象信息的形式。可选地，切换响应信令中包括的指示信息的形式，与测量报告中测量对象信息的形式相同。例如，测量报告中测量对象信息包括接收天线面板的标识和/或接收波束的标识，则切换响应信令中的指示信息包括目标天线面板的标识和/或目标波束的标识。又例如，测量报告中测量对象信息包括接收天线面板的标识和/或第一参考信号标识，则切换响应信令中的指示信息包括目标天线面板的标识和/或第二参考信号标识。
在一种可能的情况下，如果终端具有波束相关(beam correspondence)能力，也即当终端在接收目标基站发送的下行信号时，信号最优的接收天线面板和接收波束，所对应的发送天线面板和发送波束，是向该目标基站发送上行信号时的最优选择。比如，当终端在接收目标基站发送的下行信号时，无线信号强度最优的接收天线面板为panel#1和接收波束为beam#1，与该接收天线面板panel#1对应的发送天线面板为panel#1，与该接收波束beam#1对应的发送波束为beam#4，则终端采用panel#1和beam#4向目标基站发送随机接入前导码的话，目标基站的接收信号也应该是最强的。在这种情况下，目标基站根据测量报告知道了终端在与其通信时最优的接收天线面板和接收波束，则相应的也就知道了终端在与其通信时最优的发送天线面板和发送波束，并将此作为终端用于向该目标基站发送随机接入前导码的目标天线面板和目标波束。
在另一种可能的情况下，如果终端不具有波束相关能力，即终端无法由接收天线面板和接收波束直接找出相应的发送天线面板和发送波束，则服务基站向目标基站发送的切换请求信令中，还可以包括终端用于上行测量的上行参考信号的配置信息。目标基站在获得该配置信息之后，对终端发送的上行参考信号进行测量，得到各个上行参考信号对应的测量值，进而找出测量值最优的发送天线面板和发送波束，作为终端向该目标基站发送随机接入前导码时使用的目标天线面板和目标波束。
在步骤305中，服务基站向终端发送切换指令。
可选地，切换指令包括目标小区的标识，还包括目标天线面板和/或目标波束的指示信息。可选地，切换指令还包括：终端在发送随机接入前导码后，用于监听RAR的天线面板和/或波束的指示信息。
在步骤306中，终端根据切换指令，确定用于发送随机接入前导码的目标天线面板和/或目标波束。
终端接收到切换指令之后，便可以据此确定出向目标小区发起随机接入，并且确定出用于发送随机接入前导码的目标天线面板和/或目标波束，然后采用该目标天线面板和/或目标波束，向目标小区所属的目标基站发送随机接入前导码，发起随机接入。
另外，目标天线面板可以是一个，也可以是多个，目标波束也可以是一个或多个。
其中，服务基站和目标基站可以相同或不同，此处不做限制。
对于场景(1)，通过终端向服务基站发送RRM测量报告，由服务基站找出信号强度最优的邻小区作为终端切换至的目标小区，然后再由目标小区所属的目标基站确定出终端用于发送随机接入前导码的目标天线面板和目标波束，使得终端能够向信号强度最优的目标小区发起随机接入，且终端在向目标小区发起随机接入时，能够使用最优的发送天线面板和发送波束，充分确保了小区切换时的随机接入成功率。
对于场景(2)，与场景(1)相类似，随机接入指示信令为切换指令。与场景(1)不同的是，由于在该场景(2)中，终端仅一部分特定的天线面板切换至目标小区，如终端可以保留一部分天线面板与当前的服务小区通信，并将另一部分天线面板切换至另一个目标小区，在这种场景下，终端还需要向服务基站发送候选面板信息，该候选面板信息指示用于随机接入的至少一个候选天线面板。服务基站将该候选面板信息发送给目标基站，以便于目标基站从该至少一个候选天线面板中选择目标天线面板。
例如，终端有3个天线面板，分别为panel#0、panel#1和panel#2，终端选择panel#0和panel#2切换至目标小区，并保持panel#1不切换，则终端向服务基站发送的候选面板信息中可以包括这两个候选天线面板的标识，如panel#0和panel#2，目标基站就从这两个候选面板中选择一个或多个天线面板，作为终端向其发送随机接入前导码时使用的目标天线面板，如目标基站选择panel#0作为 终端发送随机接入前导码使用的目标天线面板。
对于场景(2)，通过终端向网络侧发送候选面板信息，使得目标基站从终端确定出的需要切换的若干个候选天线面板中，选择出用于发送随机接入前导码的目标天线面板，确保了终端采用合适的天线面板发起随机接入，从而提升随机接入准确性和成功率。
对于场景(3)，随机接入指示信令为无线链路恢复(Radio Link Recovery)指令或波束恢复(Beam Recovery)指令，该无线链路恢复指令用于触发终端发起无线链路恢复流程，该波束恢复指令用于触发终端发起波束恢复流程。可选地，无线链路恢复指令或波束恢复指令中包括目标天线面板和/或目标波束的指示信息，以便终端使用该目标天线面板和/或目标波束向目标基站(如服务基站)发起随机接入，进行无线链路恢复或波束恢复。
如图4所示，对于场景(3)，本公开实施例提供的随机接入指示方法可以包括如下几个步骤(401～403)：
在步骤401中，终端向服务基站发送无线链路失败通知或波束失败通知。
无线链路失败通知用于向服务基站告知发生无线链路失败的基站天线面板，也即告知服务基站该服务基站的哪个/哪些天线面板发生了无线链路失败。波束失败通知用于向服务基站告知发生波束失败的基站天线面板，也即告知服务基站该服务基站的哪个/哪些天线面板发生了波束失败。可选地，无线链路失败通知或波束失败通知中，可以包括该发生无线链路失败或波束失败的基站天线面板的指示信息。此处的基站天线面板的指示信息，可以是基站天线面板的标识，也可以使用参考信号组标识和/或参考信号标识来表示，参考信号可以是下行参考信号或上行参考信号。比如是下行参考信号的标识时，基站即得知是发送该下行参考信号的TRP或天线面板发生了波束失败，则基站需要使用该天线面板在新的波束方向来向该终端发送下行控制信令。
在步骤402中，服务基站向终端发送无线链路恢复指令或波束恢复指令。
如果终端向服务基站发送无线链路失败通知，则服务基站向终端发送无线链路恢复指令；如果终端向服务基站发送波束失败通知，则服务基站向终端发送波束恢复指令。
可选地，无线链路恢复指令或波束恢复指令中包括目标天线面板和/或目标波束的指示信息。可选地，目标天线面板为终端接收该发生无线链路失败或波 束失败的基站天线面板发送的下行信息(如下行参考信号和/或下行控制信令)时使用的天线面板。同样，此处的目标天线面板的指示信息，可以是目标天线面板的标识，也可以使用参考信号组标识和/或参考信号标识来表示，参考信号可以是下行参考信号或上行参考信号。比如是下行参考信号的标识时，终端即得知基站是需要终端使用新的波束方向，向发送该下行参考信号的基站的TRP或天线面板发起随机接入，以便基站获得向终端发送下行控制信令的新的波束方向。
如果终端不是使用上述目标天线面板，通过向服务小区发送随机接入前导码来告知服务基站，该基站天线面板发生无线链路失败或波束失败，而是使用其它方法，比如使用PUCCH(Physical Uplink Control Channel，物理上行控制信道)发送SR(Scheduling Request，调度请求)，或者使用PUSCH(Physical Uplink Shared Channel，物理上行共享信道)发送MAC(Medium Access Control，媒体接入控制)CE(Control Element,控制单元)信令，或者使用其它服务小区或其它天线面板发送随机接入前导码等方式，向服务基站发送无线链路失败通知或波束失败通知，那么服务基站在接收到该无线链路失败通知或波束失败通知之后，需要告知终端在接收该发生无线链路失败或波束失败的基站天线面板发送的下行信息(如下行参考信号和/或下行控制信令)时使用的目标天线面板上进行随机接入。服务基站向终端发送无线链路恢复指令或波束恢复指令，该无线链路恢复指令或波束恢复指令中，可以包括该目标天线面板的指示信息。
可选地，无线链路恢复指令或波束恢复指令可以是RRC(Radio Resource Control，无线资源控制)信令、MAC CE信令或者DCI(Downlink Control Information，下行控制信息)信令，本公开实施例对此不作限定。
在步骤403中，终端根据无线链路恢复指令或波束恢复指令，确定用于发送随机接入前导码的目标天线面板和/或目标波束。
终端接收到无线链路恢复或波束恢复指令之后，便可以据此确定出用于发送随机接入前导码的目标天线面板和/或目标波束，然后采用该目标天线面板和/或目标波束，向服务基站发送随机接入前导码，发起随机接入。
对于场景(3)，实现了无线链路失败或波束失败场景下的随机接入，恢复无线链路或波束。
对于场景(4)，随机接入指示信令为辅小区添加指令，该辅小区添加指令 用于指示终端接入目标辅小区。可选地，辅小区添加指令中包括目标天线面板和/或目标波束的指示信息，以便终端使用该目标天线面板和/或目标波束向目标基站(如该目标辅小区所属的基站)发起随机接入，接入该目标辅小区。
如图5所示，对于场景(4)，本公开实施例提供的随机接入指示方法可以包括如下几个步骤(501～503)：
在步骤501中，终端向服务基站发送邻小区测量报告。
可选地，邻小区测量报告包括至少一个邻小区的测量报告。邻小区的测量报告用于指示邻小区的无线信号质量。邻小区的测量报告可以包括：邻小区的标识、邻小区的测量值和测量对象信息等。邻小区的测量报告具体可参见上文的介绍说明，此处不再赘述。
在步骤502中，服务基站从至少一个邻小区中选择目标辅小区。
可选地，服务基站根据各个邻小区的测量值，选择无线信号强度最优的一个邻小区作为目标辅小区。
在步骤503中，服务基站向终端发送辅小区添加指令。
辅小区添加指令用于指示终端接入目标辅小区。可选地，辅小区添加指令中包括目标辅小区的标识。可选地，辅小区添加指令中还包括目标天线面板和/或目标波束的指示信息。有关目标天线面板和/或目标波束的指示信息的形式，可参见上文实施例中的介绍说明，此处不再赘述。
在步骤504中，终端根据辅小区添加指令，确定用于发送随机接入前导码的目标天线面板和/或目标波束。
终端接收到辅小区添加指令之后，便可以据此确定出向目标辅小区发起随机接入，并且确定出用于发送随机接入前导码的目标天线面板和/或目标波束，然后采用该目标天线面板和/或目标波束，向目标辅小区所属的基站发送随机接入前导码，发起随机接入。
