请参阅图2，图2是本申请实施例提供的一种信号传输方法的流程示意图。该信号传输方法可由终端设备执行。该信号传输方法包括以下步骤：
S101、终端设备从多个参考信号中确定参考信号接收功率RSRP大于预设值的N1个参考信号，N1为大于或等于0的整数。其中，参考信号可以是同步信号块(synchronization signal block，SSB)或信道状态信息参考信号(channel state information reference signal，CSI-RS)。可选的，所述参考信号由网络侧通过高层信令配置，其可以是用于关联Msg1传输的下行参考信号。
S102、终端设备在M个重复传输资源上分别发送随机接入消息，每个重复传输资源上发送随机接入消息采用的波束是基于N1个参考信号关联的N1个波束确定的，M为大于0的整数。
其中，参考信号关联的波束是终端设备接收该参考信号所采用的波束，如 接收波束。预设值可以是网络设备通过高层信令配置的，还可以是预定义的。
另外，M的值等于随机接入消息的重复传输次数。那么，终端设备可重复M次发送随机接入消息，每次发送的随机接入消息是在M个重复传输资源中的一个重复传输资源上发送的。其中，重复传输资源可以是随机接入机会(random access channel occasion，RO)。终端设备重复M次发送随机接入消息可对应重复传输资源集合H，重复传输资源集合H包括M个元素，如重复传输资源集合H为{H1、H2，…，HM}，其中，每个元素对应M个重复传输资源中的一个重复传输资源。

关于终端设备在M个重复传输资源上发送随机接入消息采用的波束的确定方式，以及确定的波束与M个重复传输资源之间的对应关系(也可称为映射关系)，包括但不限于实施方式A至实施方式E所述。
实施方式A，N1小于M的情况：

例如，M为3，M个重复传输资源包括重复传输资源1、重复传输资源2和重复传输资源3，M个波束包括波束1、波束2和波束3。其中，重复传输资源1在M个波束中对应的波束是波束1，重复传输资源2在M个波束中对应的波束是波束2，重复传输资源3在M个波束中对应的波束是波束3。那么，终端设备在重复传输资源1上发送随机接入信号采用波束1，重复传输资源2上发送随机接入信号采用波束2，重复传输资源3上发送随机接入信号采用波束3。
其中，按照索引大小顺序排列的M个重复传输资源与按照索引大小顺序排列的M个波束之间一一对应。
可选的，按照索引从小到大的顺序排列的M个重复传输资源与按照索引从大到小的顺序排列的M个波束一一对应。例如，结合图3a，M为3，M个重复传输资源按照索引从大到小的顺序排列为：重复传输资源1、重复传输资源2、重复传输资源3，M个波束按照索引从大到小的顺序排列为：波束1、波束2和波束3。那么，重复传输资源1与波束1对应，重复传输资源2与波束2对应，重复传输资源3与波束3对应。
可选的，按照索引从大到小的顺序排列的M个重复传输资源与按照索引从大到小的顺序排列的M个波束一一对应。例如，结合图3b，M为3，M个重复传输资源按照索引从大到小的顺序排列为：重复传输资源3、重复传输资源2、重复传输资源1，M个波束按照索引从大到小的顺序排列为：波束1、波束2和波束3。那么，重复传输资源3与波束1对应，重复传输资源2与波束2对应，重复传输资源1与波束3对应。
可选的，M个波束按照索引从大到小的顺序排列可以是M个波束按照其关联的参考信号的索引号从大到小的顺序排列。
可选的，M个重复传输资源按照索引从小到大的顺序排列可以是按照M个重复传输资源在时域上从前到后的顺序排列，或者，是按照M个重复传输资源在时域上从后到前的顺序排列。
实施方式B，N1小于M的情况：
信号传输方法还可包括：终端设备从N1个参考信号中选择N3个参考信号，N3是第一集合中小于或等于N1的值；第一集合包括重复传输次数允许选择的多个值，且多个值均为大于或者等于1的整数。每个重复传输资源上发送随机接入消息采用的波束，是每个重复传输资源在N3个参考信号关联的N3个波束中对应的波束；N3个波束按照索引的大小顺序以循环的方式与按照索引的大小顺序排列的M个重复传输资源一一对应。可选的，N3还可以是第一集合中小于或等于N1的数值中最大的一个。
例如，结合图4a，M等于8，N1等于3，第一集合包括的多个值为：2、4、6、8。可见，N1小于M，那么N3可以等于2，终端设备可从参考信号接收功率(reference signal receiving power，RSRP)大于预设值的N1个参考信号中选择2个参考信号。该2个参考信号关联的波束按照索引的大小顺序排列为：波束1、波束2，另外，8个重复传输资源按照索引的大小顺序排列为：重复传输 资源1、重复传输资源2、重复传输资源3、重复传输资源4、重复传输资源5、重复传输资源6、重复传输资源7、重复传输资源8。波束1和波束2按照上述排列以循环的方式与排列的8个重复传输资源一一对应，即波束1与重复传输资源1对应，波束2与重复传输资源2对应；循环地，波束1再与重复传输资源3对应，波束2再与重复传输资源4对应，波束1还与重复传输资源5对应，波束6还与重复传输资源6对应，波束1还与重复传输资源7对应，波束2还与重复传输资源8对应。

可选的，第一集合可以是网络设备配置给终端设备的，还可以是预定义的。第一集合中的多个值可对应相同的预设值，也可以是多个值中每个值对应各自的预设值。

例如，结合图4b，M等于8，N1等于3，多个参考信号中RSRP大于预设值的N1个参考信号关联的波束按照索引的大小顺序排列为：波束1、波束2、波束3，8个重复传输资源按照索引的大小顺序排列为：重复传输资源1、重复传输资源2、重复传输资源3、重复传输资源4、重复传输资源5、重复传输资源6、重复传输资源7、重复传输资源8。波束1、波束2和波束3按照上述排列以循环的方式与排列的8个重复传输资源一一对应，即波束1与重复传输资源1对应，波束2与重复传输资源2对应，波束3与重复传输资源3对应；循环地，波束1再与重复传输资源4对应，波束2再与重复传输资源5对应，波 束3再与重复传输资源6对应，波束1还与重复传输资源7对应，波束2还与重复传输资源8对应。
实施方式D，N1小于M，且M与N1之比为整数的情况：

按照索引的大小顺序排列后的N1个波束以每个波束连续重复X次的方式与按照索引的大小顺序排列的M个重复传输资源一一对应，X等于M与N1之比。也就是说，按照索引的大小顺序排列后的N1个波束可按照循环映射(cyclic mapping)的策略与按照索引的大小顺序排列的M个重复传输资源一一对应。
例如，结合图5a，M等于8，N1等于2，多个参考信号中RSRP大于预设值的N1个参考信号关联的N1个波束按照索引的大小顺序排列为：波束1、波束2，8个重复传输资源按照索引的大小顺序排列为：重复传输资源1、重复传输资源2、重复传输资源3、重复传输资源4、重复传输资源5、重复传输资源6、重复传输资源7、重复传输资源8。排列后的波束1和波束2以每个波束连续重复4(即X)次的方式与排列的M个重复传输资源一一对应，即波束1与排列连续的重复传输资源1、重复传输资源2、重复传输资源3、重复传输资源4对应，波束2与排列连续的重复传输资源5、重复传输资源6、重复传输资源7、重复传输资源8对应。
可选的，按照索引的大小顺序排列后的N1个波束以每个波束连续重复X次的方式与按照索引的大小顺序排列的M个重复传输资源一一对应，可以是：按照索引从大到小的顺序排列后的N1个波束，以每个波束连续重复X次的方式与按照索引从大到小的顺序排列的M个重复传输资源一一对应；或者，可以是按照索引从大到小的顺序排列后的N1个波束，以每个波束连续重复X次的方式与按照索引从小到大的顺序排列的M个重复传输资源一一对应。
实施方式E，N1小于M，且M与N1之比不为整数的情况：
每个重复传输资源上发送随机接入消息采用的波束，是每个重复传输资源在N1个参考信号关联的N1个波束中对应的波束。
按照索引大小顺序排列后的N1个波束以每个波束连续重复X次的方式与按照索引大小顺序排列的M1个重复传输资源一一对应，X等于M与N1之比向下取整的值；M1等于X与N1之积，M1个重复传输资源是M个重复传输资 源中索引最小或最大的M1个重复传输资源。
按照索引大小顺序排列后的N4个波束以每个波束连续重复X次的方式与按照索引大小顺序排列的M2个重复传输资源一一对应。N4等于M2与X之比向上取整的值；N4个波束是N1个波束中索引最小或最大的波束；M2等于M与M1之差；M2个重复传输资源是M个重复传输资源中除M1个重复传输资源外的重复传输资源。
也就是说，按照索引的大小顺序排列后的N1个波束可按照循环映射(cyclic mapping)的策略与按照索引的大小顺序排列的M个重复传输资源一一对应。
例如，结合图5b，M等于8，N1等于3，多个参考信号中RSRP大于预设值的N1个参考信号关联的N1个波束按照索引的大小顺序排列为：波束1、波束2、波束3，8个重复传输资源按照索引的大小顺序排列为：重复传输资源1、重复传输资源2、重复传输资源3、重复传输资源4、重复传输资源5、重复传输资源6、重复传输资源7、重复传输资源8。排列后的波束1、波束2和波束3以每个波束连续重复2(即X)次的方式与排列的前6(即M1)个重复传输资源一一对应，即波束1与排列连续的重复传输资源1、重复传输资源2对应，波束2与排列连续的重复传输资源3、重复传输资源4对应，波束3与排列连续的重复传输资源5、重复传输资源6对应。排列在前的1(即N4)个波束与8个重复传输资源中除上述6个重复传输资源外的2(即M2)个重复传输资源对应，即波束1还与排列连续的重复传输资源7、重复传输资源8对应。
可选的，按照索引从大到小的顺序排列后的N1个波束，以每个波束连续重复X次的方式与按照索引从大到小的顺序排列的M1个重复传输资源一一对应；按照索引从大到小的顺序排列后的N4个波束以每个波束连续重复X次的方式与按照索引从大到小的顺序排列的M2个重复传输资源一一对应。
可选的，按照索引从大到小的顺序排列后的N1个波束，以每个波束连续重复X次的方式与按照索引从小到大的顺序排列的M1个重复传输资源一一对应；按照索引从大到小的顺序排列后的N4个波束以每个波束连续重复X次的方式与按照索引从小到大的顺序排列的M2个重复传输资源一一对应。
上述实施方式A至实施方式E可应用于终端设备采用不同波束重复M次发送随机接入消息的情况下，终端设备确定每次发送随机接入消息所采用的波束。实施方式B至实施方式E还可应用于，M次发送随机接入消息所采用的的波束 个数小于M时，存在一个波束与M个重复传输资源中多个重复传输资源对应的情况下，终端设备确定M次发送随机接入消息所采用的波束与M个重复传输资源之间的对应关系。
综上所述，该信号传输方法中，终端设备从多个参考信号中确定RSRP大于预设值的N1个参考信号，N1为大于或等于0的整数；终端设备在M个重复传输资源上分别发送随机接入消息，每个重复传输资源上发送随机接入消息采用的波束是基于N1个参考信号关联的N1个波束确定的。可见，终端设备可基于多个参考信号中RSRP大于预设值的N1个参考信号关联的波束，确定在每个重复传输资源上发送随机接入消息采用的波束。该信号传输方法可实现终端设备重复多次发送随机接入消息，从而增强随机接入过程中的上行覆盖，可提高终端设备随机接入的成功率。
