图2是根据本申请实施例的传输信号的方法200性流程图。如图2所示，该方法可以由终端设备执行，该传输信号的具体流程包括：
在210中，终端设备确定N组随机接入信号的波束信息。
其中，N组随机接入信号的波束信息相同，且每组随机接入信号中包括M个随机接入信号，M为正整数，N为正整数。
具体地说，终端设备在向网络设备发送上行随机接入信号(本申请实施例中简称为随机接入信号)时，首先以N组随机接入信号为单位进行波束信息的确定，终端设备为N组随机接入信号确定波束信息后，可以根据该波束信息向网络设备发送这N组随机接入信号，其中，每组随机接入信号中包括M个随机接入信号。
可选地，用于发送每组随机接入信号中的M个随机接入信号的波束相同或不同。
也就是说，每组随机接入信号中的M个随机接入信号，可以使用相同的波束进行发送，也可以分别使用不同的波束进行发送。
可选地，每组随机接入信号的波束信息包括用于发送M个随机接入信号的波束，和/或用于发送随机接入信号的时频资源位置与波束的对应关系。
例如，若用于发送每组随机接入信号中的M个随机接入信号的波束相同，则该波束信息中可以包括这该M个随机接入信号所使用的波束。
又例如，若用于发送每组随机接入信号中的M个随机接入信号的波束不相同，则该波束信息中可以包括用于发送随机接入信号的时频资源位置与波束的对应关系。这里的时频资源位置为相对的时频资源位置，某个随机接入信号使用的波束，与该随机接入信号的时频资源在该组随机接入信号的时频资源中的相对位置相对应。
举例来说，如图3所示的N组随机接入信号的传输示意图，图3中以N＝2，M＝4为例，也就是终端设备传输两组随机接入信号，且每组随机接入信号中都包括四个随机接入信号，并且每组中的四个随机接入信号使用的波束相同，都为波束(Beam)1，这时，这两组随机接入信息的波束信息就可以包括波束1的信息。
又例如，如图4所示的N组随机接入信号的传输示意图，图4中以N＝4，M＝2为例，也就是终端设备发送四组随机接入信号，且每组随机接入信号中都包括两个随机接入信号，并且每组中的两个随机接入信号使用的波束不相同。这时，这两组随机接入信号的波束信息就可以包括用于发送随机接入信号的时频资源位置与波束的对应关系，终端设备根据该波束信息，以及每组中的两个随机接入信号各自对应的资源位置，确定每个随机接入信号使用的波束。假设该波束信息中的该对应关系为表一所示，表一示出了用于时域资源位置与波束的对应关系，每组中的第一个的随机接入信号占用第一个符号发送，每组中的第二个随机接入信号占用第二个符号发送，因此终端设备根据表一可以确定第一个随机接入信号使用波束1，第二个随机接入信号使用波束2。
表一
时域资源位置 波束
第一个符号 波束1
第二个符号 波束2
可选地，在终端设备确定N组随机接入信号的波束信息之前，该方法还包括：终端设备接收网络设备发送的指示信息，该指示信息用于指示N和/或M。
应理解，M和N的值也可以由终端设备和网络设备之间事先约定例如协议中规定的M和N的值。
可选地，若该指示信息用于指示N，则M等于预设值；或者，若该指示信息用于指示M，则N等于预设值。
例如，若终端设备接收的指示信息中仅包括N，那么终端设备可以根据预设的M＝1，确定每组中只包括一个随机接入信号。
可选地，用于发送所述M个随机接入信号的时域资源、用于发送所述M个随机接入信号的频域资源和所述M个随机接入信号所使用的序列中的至少一项相同，或者全不相同。
可选地，用于发送M个随机接入信号的时频资源满足预设的跳频模式。
具体地说，终端设备发送M个随机接入信号的时频资源，可以满足预设的跳频(hopping)模式，例如在某个或某些域(时域、频域、序列资源)上采用hoppig的方式，网络通过配置hopping相关参数，则可以由前面的某个参考配置参数得到后续对应的参数，使终端设备可以按照配置的跳频模式来发送M个随机接入信号。
可选地，用于发送M个随机接入信号的时频资源在时域上连续或不连续。
也就是说，每组中的M个随机接入信号的时频资源在时域上可以是连续发送的例如图3和图4所示的情况，每组中的M个随机接入信号的时频资源在时域上也可以不连续，或者部分连续，这里不做限定。
在220中，若终端设备根据N组随机接入信号的波束信息向网络设备发送N组随机接入信号，且没有接收到网络设备针对N组随机接入信号发送的随机接入响应(Random Access Response，简称“RAR”)消息，则重新确定N组随机接入信号的波束信息。本申请实施例中将随机接入响应消息(RAR消息)简称为响应消息。
在230中，终端设备根据重新确定的N组随机接入信号的波束信息，向网络设备重新发送N组随机接入信号中的至少一个随机接入信号。
可选地，终端设备重新确定的N组随机接入信号的波束信息，与前一次 发送的N组随机接入信号的波束信息不相同。
具体地说，终端设备确定好当前的N组随机接入信号的波束信息后，可以根据N组随机接入信号的波束信息向网络设备依次发送N组随机接入信号中的每组随机接入信号，如果终端设备根据N组随机接入信号的波束信息向网络设备发送了N组随机接入信号，但没有接收到网络设备针对N组随机接入信号发送的响应消息，则终端设备需要重新确定N组随机接入信号的波束信息，并根据重新确定的波束信息重新发送随机接入信号，这里，不同的波束信息表示了不同的发送波束模式(pattern)，即用于传输随机接入信号不同资源位置与不同传输波束之间的对应关系。
可选地，如果终端设备在N组随机接入信号的发送过程中，接收到网络设备发送的针对N组随机接入信号中已发送的至少一个随机接入信号的响应消息，则停止向网络设备发送N组随机接入信号中其他未发送的随机接入信号。
举例来说，如图5所示的N组随机接入信号的发送示意图，图5中以N＝2，M＝4为例，也就是终端设备当前发送两组随机接入信号，且每组随机接入信号中都包括四个随机接入信号，并且每组中的四个随机接入信号使用的波束相同。假设终端设备当前发送的两组随机接入信号的波束信息指示波束1，终端设备首先使用波束1向网络设备发送第一组随机接入信号，若终端设备没有接收到网络设备针对第一组随机接入信号发送的响应消息，那么终端设备仍使用波束1向网络设备发送第二组随机接入信号，这里由于两组随机接入信号的波束信息相同即都为波束1，因此两组随机参考信号都是用波束1发送。如果终端设备也没有接收到网络设备针对第二组随机接入信号发送的响应消息，那么终端设备需要重新确定两组随机接入信号的波束信息，并且根据重新确定的波束信息，向网络设备发送随机接入信号。
假设终端设备重新确定的波束信息指示波束2，那么终端设备继续使用波束2向网络设备发送第一组随机接入信号，若终端设备没有接收到网络设备针对第一组随机接入信号发送的响应消息，那么仍使用波束2向网络设备发送第二组随机接入信号，这里由于重新确定的两组随机接入信号的波束信息为波束2，因此两组随机参考信号都用波束2重新进行了发送。
如果终端设备接收到网络设备针对第一组随机接入信号发送的响应消息，那么终端设备停止发送第二组随机接入信号。
又例如，如图6所示的N组随机接入信号的传输示意图，图6中以N＝4，M＝2为例，也就是终端设备发送四组随机接入信号，且每组随机接入信号中都包括两个随机接入信号，并且每组中的两个随机接入信号使用的波束不相同。
假设终端设备当前待发送的四组随机接入信号的波束信息包括表一所示的用于发送随机接入信号的时频资源位置与波束的对应关系，那么终端设备使用波束1向网络设备发送第一组中占用第一个符号的随机接入信号，并使用波束2向网络设备发送第一组中占用第二个符号的随机接入信号。若终端设备没有接收到网络设备针对第一组随机接入信号发送的响应消息，那么终端设备仍使用波束1向网络设备发送第二组中占用第一个符号的随机接入信号，并使用波束2向网络设备发送第二组中占用第二个符号的随机接入信号，若果仍未接收到网络设备发送的响应消息，那么终端设备根据表一所示的波束信息继续向网络设备发送第三组随机接入信号，依次类推，如果终端设备向网络设备发送了最后一组即第四组随机接入信号后，仍未接收到网络设备发送的响应消息，则终端设备需要重新确定四组随机接入信号的波束信息，并且根据重新确定的波束信息，向网络设备发送随机接入信号。
假设终端设备重新确定的波束信息包括表二所示的用于发送随机接入信号的时频资源位置与波束的对应关系，那么终端设备使用波束3向网络设备发送第一组中占用第一个符号的随机接入信号，并使用波束3向网络设备发送第一组中占用第二个符号的随机接入信号。若终端设备没有接收到网络设备针对第一组随机接入信号发送的响应消息，那么终端设备根据表二所示的波束信息继续向网络设备发送下一组随机接入信号，依次类推，若终端设备在随机接入信号的发送过程中，接收到网络设备针对四组随机接入信号中已发送的随机接入信号的响应消息，则终端设备停止向网络设备发送四组随机接入信号中其他未发送的随机接入信号。
表二
时域资源位置 波束
第一个符号 波束3
第二个符号 波束3
应理解，终端设备在检测网络设备发送的响应消息时，可以在发送随机接入信号的同时进行响应消息的检测，如果检测到网络设备发送的响应消 息，则停止随机接入信号的发送。例如，假设M＝4，N＝2，如果终端设备在发送第一组随机接入信号中的第一个随机接入信号后，就检测到网络设备发送的响应消息，那么终端设备就不必发送第一组中的第二个至第四个随机接入信号，也不必发送第二组中的随机接入信号了。
也可以在发送完一组随机接入信号后，再对针对该组随机接入信号的响应消息进行检测(例如图5和图6所示)，如果检测到网络设备发送的响应消息，则不必发送后面几组随机接入信号，如果没有检测到网络设备发送的响应消息，则继续发送下一组随机接入信号，并在下一组随机接入信号发送完毕后，检测针对下一组随机接入信号的响应消息。例如，假设M＝4，N＝2，终端设备发送第一组随机接入信号中的四个随机接入信号后，检测到网络设备发送的针对第一组随机接入信号的响应消息。如果检测到响应消息，则停止随机接入信号的发送；如果终端设备发送第一组随机接入信号中的四个随机接入信号后，没有检测到网络设备发送的响应消息，那么继续发送第二组随机接入信号中的四个随机接入信号。
因此，终端设备通过使用相同的波束信息向网络设备发送N组随机接入信号，使得网络设备可以有效地确定与用于发送随机接入信号的发送波束匹配的接收波束，以成功接收终端设备发送的随机接入信号，从而提高了终端设备随机接入的效率，降低了时延。
图7是根据本申请实施例的传输信号的方法300性流程图。如图7所示，该方法可以由网络设备执行，该传输信号的具体流程包括：
在310中，若网络设备没有成功接收终端设备根据N组随机接入信号的波束信息发送的N组随机接入信号，则确定禁止向终端设备发送针对N组随机接入信号的响应消息。
其中，N组随机接入信号的波束信息相同，且每组随机接入信号中包括M个随机接入信号，M为正整数，N为正整数。
具体地说，网络设备接收终端设备发送的随机接入信号后，可能由于接收随机接入信号的接收波束与终端设备发送该随机接入信号的发送波束之间的不匹配而导致随机接入信号的接收失败，或者该接收波束与该发送波束匹配度较差不能满足网络需求，因此网络设备需要根据随机接入信号的接收结果，确定是否向终端设备发送针对该随机接入信号的响应消息。本申请实施例中，终端设备在向网络设备发送随机接入信号时，会以N组随机接入信 号为单位进行波束信息的确定。如果网络设备没有成功接收终端设备根据N组随机接入信号的波束信息发送的N组随机接入信号，或者网络设备认为接收随机接入信号的接收波束与终端设备发送该随机接入信号的发送波束之间的匹配度较差不能满足网络需求，那么网络设备不会向终端设备发送针对N组随机接入信号的响应消息。
可选地，用于发送每组随机接入信号中的M个随机接入信号的波束相同或不同。
也就是说，每组随机接入信号中的M个随机接入信号，可以使用相同的波束进行发送，也可以分别使用不同的波束进行发送。
可选地，每组随机接入信号的波束信息包括用于发送M个随机接入信号的波束，和/或用于发送随机接入信号的时频资源位置与波束的对应关系。
例如，若用于发送每组随机接入信号中的M个随机接入信号的波束相同，则该波束信息中可以包括这该M个随机接入信号所使用的波束。
又例如，若用于发送每组随机接入信号中的M个随机接入信号的波束不相同，则该波束信息中可以包括用于发送随机接入信号的时频资源位置与波束的对应关系。
其中，根据波束信息进行N组随机接入信号的传输情况例如可以参考前述对图3和图4的相关描述。为了简洁，这里不再赘述。
可选地，在网络设备接收终端设备根据N组随机接入信号的波束信息发送的N组随机接入信号之前，该方法还包括：网络设备向终端设备发送指示信息，该指示信息用于指示N和/或M。
应理解，M和N的值也可以由终端设备和网络设备之间事先约定例如协议中规定的M和N的值。
可选地，若该指示信息用于指示N，则M等于预设值；或者，若该指示信息用于指示M，则N等于预设值。
例如，若终端设备接收的指示信息中仅包括N，那么终端设备可以根据预设的M＝1，确定每组中只包括一个随机接入信号。
可选地，用于发送所述M个随机接入信号的时域资源、用于发送所述M个随机接入信号的频域资源和所述M个随机接入信号所使用的序列中的至少一项相同，或者全不相同。
可选地，用于发送M个随机接入信号的时频资源满足预设的跳频模式。
可选地，用于发送M个随机接入信号的时频资源在时域上连续或不连续。
在320中，网络设备重新接收终端设备根据重新确定的N组随机接入信号的波束信息发送的N组随机接入信号中的至少一个随机接入信号。
可选地，终端设备重新确定的N组随机接入信号的波束信息，与前一次发送的N组随机接入信号的波束信息不相同。
可选地，若网络设备在N组随机接入信号的接收过程中，成功接收到终端设备发送的随机接入信号，则向终端设备发送针对N组随机接入信号中已接收的至少一个随机接入信号的响应消息。
具体地说，如果网络设备没有成功接收终端设备根据N组随机接入信号的波束信息发送的N组随机接入信号，网络设备不会向终端设备发送针对N组随机接入信号的响应消息，那么终端设备由于没有接收到网络设备针对N组随机接入信号发送的响应消息，需要重新确定N组随机接入信号的波束信息，并根据重新确定的波束信息重新发送随机接入信号。因此网络设备可以重新接收终端设备根据重新确定的N组随机接入信号的波束信息发送的N组随机接入信号中的至少一个随机接入信号。
如果网络设备在N组随机接入信号的接收过程中，成功接收到终端设备发送的随机接入信号，网络设备会向终端设备发送针对N组随机接入信号中已接收的至少一个随机接入信号的响应消息，那么终端设备在N组随机接入信号的发送过程中，就可以接收到网络设备发送的针对N组随机接入信号中已发送的至少一个随机接入信号的响应消息，并会停止向网络设备发送N组随机接入信号中其他未发送的随机接入信号。
其中，根据波束信息进行N组随机接入信号的传输情况例如可以参考前述对图5和图6的相关描述。为了简洁，这里不再赘述。
本申请实施例中，网络设备通过接收终端设备使用相同的波束信息发送的N组随机接入信号，可以有效地确定与用于发送随机接入信号的发送波束匹配的接收波束，以成功接收终端设备发送的随机接入信号，从而提高了终端设备随机接入的效率，降低了时延。
