在现有的长期演进(Long Team,LTE)系统中,当网络设备检测到终端设备发送的随机接入前导码时,网络设备将在物理下行共享信道(Physical Downlink Shared CHannel,PDSCH)上发送随机接入响应RAR(Random Access Response,RAR)消息。该RAR消息包含网络设备检测到的随机接入前导序列的索引号、用于上行同步的时间调整信息、初始的上行资源分配(用于发送随后的msg3)以及一个临时的小区无线网络临时标识(Cell-Radio Network Temporary Identifier,C-RNTI)。
终端设备发送随机接入前导码后,需要使用随机接入无线网络临时标识(Random Access-Radio Network Temporary Identifier,RA-RNTI)来监听物理下行控制信道(Physical Downlink Control Channel,PDCCH)以用于接收属于自己RAR消息。

可选地,在本申请实施例中,终端设备也可以将终端设备的标识信息携带在随机接入请求消息中。
可选地,在本申请实施例中,随机接入请求消息也可以仅携带随机接入前导码,此时,随机接入前导码即为随机接入请求消息。

可选地,用于确定RA-RNTI的信息中,待发送的随机接入响应占用的资源信息包括:发送随机接入响应消息的下行波束的信息。其中,该发送随机接入响应消息的下行波束的信息可以包括该下行波束的编号和/或该下行波束所属的波束组的编号。
其中,网络设备可以将终端设备期望的下行波束作为发送随机接入响应消息的波束。或者,网络设备也可以根据多个波束中承载的信号的质量和/或各个波束受到的干扰,从多个波束中选择发送随机接入响应消息的波束。或者,网络设备也可以即参考终端设备期望的下行波束,又参考多个波束中承载的信号的质量和/或各个波束受到的干扰,来确定用于发送随机接入响应消息的波束,例如,只有在终端设备期望的下行波束的信号的质量大于等于预定值时,才将终端设备期望的下行波束作为发送随机接入响应消息的波束,否则,从多个波束中,重新选择用于发送随机接入响应消息的波束。
可选地,用于确定RA-RNIT的信息中,该随机接入请求消息携带的除该随机接入前导码之外的信息包括以下中的至少一种:该终端设备的标识,和该终端设备期望该网络设备采用的下行波束的信息。其中,该终端设备期望该网络设备采用的下行波束的编号和/或该下行波束所属的波束组的编号。
可选地,可以根据随机接入前导码的编号确定RA-RNTI。
可选地,可以根据随机接入请求消息占用的资源信息和/或随机接入前导码对应的波束确定RA-RNTI。
具体地说,不同的资源和/或随机接入前导码可以对应的不同的波束,终端设备在确定波束之后,可以获取该波束对应的资源和/或随机接入前导码,并进行随机接入请求消息的发送。
其中,该随机接入请求消息占用的资源信息和/或随机接入前导码对应的波束可以是终端设备期望网络设备发送随机接入响应的下行波束。
可选地,在该终端设备期望该网络设备采用的下行波束不同于承载随机接入响应的下行波束时,可以根据该终端设备期望该网络设备采用的下行波束的信息,确定该RA-RNTI;或,根据承载该随机接入响应的下行波束的 信息,确定该RA-RNTI。

具体地说,由于终端设备在采用多波束的方式发送随机接入请求消息时,终端设备并不知道哪个波束发送的随机接入请求消息会被网络设备接收到,由于采用不同的波束发送随机接入请求消息时,不同的波束对应的起始子帧并不相同,如果采用子帧的编号确定RA-RNTI,则会出现多个波束对应多个RA-RNTI的情况,则终端设备需要尝试多个RA-RNTI进行随机接入响应消息的监听,会加重终端设备的处理负担。
其中,在通过多波束发送随机接入请求消息时,每个波束占用的频域资源和/或起始无线帧相同。
因此,在本申请实施例中,根据所述随机接入请求消息占用的起始无线帧信息,所述随机接入请求消息占用的频域信息和所述随机接入请求消息中携带的除所述随机接入前导码之外的信息中的至少一种确定RA-RNTI,可以确定出唯一的RA-RNTI,终端设备可以利用该唯一的RA-RNTI,进行随机接入响应消息的监听,可以减轻终端设备的处理负担。
