本申请实施例涉及通信技术领域,具体涉及一种随机接入方法及终端设备、网络设备。
背景技术
在基于竞争的随机接入过程中,通常可以采用四部接入法,即接入请求(Message 1,Msg1)、接入响应(Message 2,Msg2)、调度传输(Message 3,Msg3)和冲突解决(Message 4,Msg4)。
然而,由于现有的基于竞争的随机接入过程中,需要四个独立的步骤,其中包括两次终端设备与网络设备之间的信息交互,其所带来的时延开销较大。这种方式,对于诸多的低时延场景例如,5G中的低时延高可靠通信(Ultra-Reliable Low Latency Communication,URLLC)场景等场景来说,是无法适用的。
因此,亟需提供一种能够适用于低时延场景的随机接入方法,以实现终端设备的随机接入。

230、所述终端设备在第四资源上接收第四信息。
本申请的主要思想是:通过将现有的四步基于竞争的随机接入过程的第一步(Msg1)和第三步(Msg3)合并为本申请所提供的随机接入过程中的第一步(Message A,Msg A),现有的四步基于竞争的随机接入过程的第二步(Msg2)和第四步(Msg4)合并为本申请所提供的两步基于竞争的随机接入过程中的第二步(Message B,Msg B)。这样,一次完整的随机接入流程从四步简化为两步,只需要终端设备与网络设备之间进行一次信息交互,能够有效降低随机接入的时延开销,从而实现了低时延场景下终端设备的随机接入。
本申请中,两步基于竞争的随机接入过程可以如图2B所示,其基本特征包括一条终端设备发送的请求消息(Msg A)和一条终端设备接收的响应消息(Msg B)。具体地,在两步基于竞争的随机接入过程中的第一步中,终端设备需要发送第一信息如前导码信息(Preamble),以及第二信息如数据信息,例如,通过在物理随机接入信道(Physical Random Access CHannel,PRACH)机会(PRACH occasion,RO)资源上发送Preamble,在物理上行共享信道(Physical Uplink Shared CHannel,PUSCH)资源上发送数据信息。
基于上述分析,可以发现,两步基于竞争的随机接入过程可以带来随机接入的步骤简化、时延缩短等好处。
可选地,在本实施例的一个可能的实现方式中,在210中,所述终端设备具体可以在第一资源上向网络设备发送第一信息,在第二资源上向所述网络设备发送第二信息。

或者,再例如,所述高层信令可以是媒体访问控制(Media Access Control,MAC)控制元素(Control Element,CE)消息,具体还可以通过增加新的MAC CE消息携带配置信息,用以指示所述一组第一预配资源。
或者,再例如,所述物理层信令可以是下行控制信息(Downlink control information,DCI),具体可以通过DCI携带配置信息,用以指示所述一组第一预配资源。
在该实现过程中,所述终端设备从所述一组第一预配资源中,选择一个第一预配资源的方式,与现有技术类似,可以是将同步信号块(Synchronization Signal Block,SSB)即SS/PBCH block与第一预配资源进行关联。其中,SSB与第一预配资源的关联方式,可以由协议约定,或者还可以由所述网络设备指示,本实施例对此不进行特别限定。其中,主同步信号(Primary Synchronization Signal,PSS)、辅同步信号(Secondary Synchronization Signal,SSS)和物理广播信道(Physical Broadcast Channel,PBCH)共同构成一个同步信号块(Synchronization Signal Block,SSB)即SS/PBCH block。网络设备指示SSB与第一预配资源的关联方式的详细描述,可以参见网络设备指示所述一组第一预配资源的相关内容。

在该实现过程中,所述终端设备从所述一组第二预配资源中,选择一个第二预配资源的方式,可以是将SSB与第二预配资源进行关联,或者还可以是将第一预配资源与第二预配资源进行关联。其中,SSB与第二预配资源的关联方式,以及第一预配资源与第二预配资源的关联方式,可以由协议约定,或者还可以由所述网络设备指示,本实施例对此不进行特别限定。网络设备指示SSB与第二预配资源的关联方式的详细描述,以及网络设备指示第一预配资源与第二预配资源的关联方式的详细描述,可以参见网络设备指示所述一组第一预配资源的相关内容。

可选地,在本实施例的一个可能的实现方式中,在220和230中,所述终端设备具体可以在第一窗口内在一组第三预配资源上检测网络设备发送的第三信息,进而,所述终端设备则可以根据检测到的所述第三信息,在第四资源上检测网络设备发送的第四信息。
Msg B可以由第三信息(如PDCCH上承载的控制信息)和第四信息(如PDSCH上承载的数据信息)组成。
第三资源是一组第三预配资源中的一个,例如,周期性出现的预配资源构成的控制资源集(CORESET)中的一个预配资源。在CORESET上,通过物理下行控制信道(Physical Downlink Control CHannel,PDCCH)传输第三信息。所述第三信息,可以用于指示发送第四信息的第四资源的资源位置,可以包括但不限于时域资源位置和/或频域资源位置。

在本申请所提供的两步基于竞争的随机接入过程中,终端设备检测Msg B的时序应该如何确定呢?针对这一问题,考虑到终端设备检测复杂度和网络侧调度的灵活度需求,终端设备在第二资源上向网络设备发送第二信息之后,终端设备具体则可以在第一窗口内在一组第三预配资源上检测第三信息。具体地,所述终端设备具体可以在第一窗口内,在一组第三预配资源上检测是否有第三序列加扰的第三信道,如图2F所示。终端设备获得CORESET的配置信息,该配置信息指示一组周期出现的CORESET位置,终端设备在这组CORESET上检测Msg B。其中,CORESET中承载的PDCCH中的DCI消息指示终端设备接收数据的时频资源配置,及其他配置信息。终端设备根据DCI消息,确定接收数据的时频资源位置及配置信息,并在确定的时频资源位置上基于配置信息指示内容接收数据。

在本申请所提供的两步基于竞争的随机接入过程中,考虑一些特殊情况,例如,终端设备发送了Msg A中的第一信息和第二信息,但是,网络设备只接收到了Msg A的部分信息如只接收到Msg A的第一信息,尚未接收到Msg A的第二信息。那么,此时,如果终端设备重新发送Msg A显然是不必要的,而是网络设备则可以直接基于接收到的第一信息,在第五资源上发送第五信息。也就是说,将终端设备所发起的两步基于竞争的随机接入过程回退为现有的四步基于竞争的随机接入过程。
可选地,在本实施例的一个可能的实现方式中,所述终端设备还可以进一步可以在一组第五预配资源上检测第五信息。
第五资源是一组第五预配资源中的一个,例如,周期性出现的预配资源构成的控制资源集 (CORESET)中的一个预配资源。在CORESET上,通过物理下行控制信道(Physical Downlink Control CHannel,PDCCH)传输第五信息,如随机接入响应(Random Access Response,RAR)消息。所述第五信息,可以用于指示发送第六信息的第六资源的资源位置,可以包括但不限于时域资源位置和/或频域资源位置。
所述一组第五预配资源可以由协议约定,或者还可以由所述网络设备指示,本实施例对此不进行特别限定。
具体来说,所述终端设备具体可以接收网络设备发送的下列信息中的至少一项,用以指示所述一组第五预配资源:
系统广播消息;
高层信令;以及
物理层信令。
这些信息具体可以指示所述一组第五预配资源的资源位置,可以包括但不限于时域资源位置和/或频域资源位置。
例如,具体可以采用系统广播消息中现有的主信息块(Master Information Block,MIB)或系统信息块(System Information Block,SIB)携带配置信息,用以指示所述一组第五预配资源,或者还可以增加新的SIB携带配置信息,用以指示所述一组第五预配资源。
或者,再例如,所述高层信令可以是无线物理资源控制(Radio Resource Control,RRC)消息,具体可以通过RRC消息中的信息元素(Information Element,IE)携带配置信息,用以指示所述一组第五预配资源,所述RRC消息可以为现有技术中的RRC消息,例如,RRC连接重配置(RRC CONNECTION RECONFIGURATION)消息等,本实施例对此不进行限定,通过对已有的RRC消息的IE进行扩展携带配置信息,用以指示所述一组第五预配资源,或者所述RRC消息也可以为不同于现有技术中已有的RRC消息。
或者,再例如,所述高层信令可以是媒体访问控制(Media Access Control,MAC)控制元素(Control Element,CE)消息,具体还可以通过增加新的MAC CE消息携带配置信息,用以指示所述一组第五预配资源。
或者,再例如,所述物理层信令可以是下行控制信息(Downlink control information,DCI),具体可以通过DCI携带配置信息,用以指示所述一组第五预配资源。
具体地,终端设备具体可以在一组第五预配资源上检测第五信道(如承载的RAR消息的PDCCH),进而,则可以在第五信道上获取网络设备发送的第五信息(如RAR消息)。
在该实现过程中,所述终端设备在一组第五预配资源上检测第五信道(如承载的RAR消息的PDCCH)的方法,可以是在一组第五预配资源上检测是否有第五序列(如特定无线网络临时标识(Radio Network Temporary Identity,RNTI))加扰的第五信道,例如,UE在预配置的RAR消息的CORESET上检测特定RNTI加扰的PDCCH,如图2G所示。终端设备根据检测到的PDCCH,确定接收RAR消息的时频资源位置及配置信息,并在确定的时频资源位置上基于配置信息指示内容接收RAR消息。终端设备根据RAR消息,确定Msg3的发送资源及发送配置,继续基于竞争的四步随机接入过程。
在一个具体的实现过程中,所述终端设备具体可以在所述第一窗口内在所述一组第五预配资源上检测所述第五信息。
在该实现过程中,出现了所述终端设备在第一窗口内,同时检测Msg B和第五信息的情况,此时,需要进一步处理两种检测之间的关联关系,避免造成不必要的冗余检测操作,避免带来终端设备冗余检测所造成的行为不确定性。基于上述考虑,存在以下两种情况:
例如,若所述终端设备检测到所述第三信息,所述终端设备则可以停止在所述第一窗口内在所述一组第五预配资源上检测所述第五信息。
终端设备在第一窗口内检测到所述第三信息时对应的情况是:终端设备向网络设备发送Msg A之后,接收到的响应消息并不是四步基于竞争的随机接入过程的RAR消息,而是两步基于竞争的随机接入过程的Msg B,此时,两步基于竞争的随机接入过程正常进行。在上述情况下,终端设备则 可以停止在第一窗口内在所述一组第三预配资源上继续检测Msg B,也就是终端设备停止在第一窗口内在一组第三预配资源上继续检测是否有第三序列加扰的第三信道,以及终端设备则可以停止在第一窗口内在所述一组第五预配资源上继续检测RAR消息,也就是终端设备停止在第一窗口内在一组第五预配资源上继续检测是否有第五序列加扰的第五信道,如图2H所示。终端设备获得RAR消息的CORESET的配置信息,终端设备在这组CORESET上检测RAR消息。终端设备获得Msg B的CORESET的配置信息,终端设备在这组CORESET上检测Msg B。终端设备检测到Msg B,Msg B的CORESET中承载的PDCCH中的DCI消息指示终端设备接收数据的时频资源配置,及其他配置信息。终端设备根据DCI消息,确定接收数据的时频资源位置及配置信息,并在确定的时频资源位置上基于配置信息指示内容接收数据。
或者,再例如,若所述终端设备检测到所述第五信息,所述终端设备则可以停止在所述第一窗口内在所述一组第三预配资源上检测所述第三信息,进而,所述终端设备则可以在第六资源上发送第六信息。

终端设备在第一窗口内检测到RAR消息时对应的情况是:终端设备向网络设备发送Msg A之后,接收到的响应消息并不是两步基于竞争的随机接入过程的Msg B,而是四步基于竞争的随机接入过程的RAR消息,此时,两步基于竞争的随机接入过程回退为四步基于竞争的随机接入过程。在上述情况下,终端设备则可以停止在第一窗口内在所述一组第五预配资源上继续检测RAR消息,也就是终端设备停止在第一窗口内在一组第五预配资源上继续检测是否有第五序列加扰的第五信道,以及终端设备则可以停止在第一窗口内在所述一组第三预配资源上继续检测Msg B,也就是终端设备停止在第一窗口内在一组第三预配资源上继续检测是否有第三序列加扰的第三信道。在终端设备检测到RAR消息之后,在RAR消息中获得Msg3发送的第六资源的资源位置的指示,以及发送方式,终端设备在所指示的资源位置上,利用所指示的发送方式,发送第六信息,如图2I所示。终端设备获得RAR消息的CORESET的配置信息,终端设备在这组CORESET上检测RAR消息。其中,RAR消息中指示Msg3发送所需要的资源信息。终端设备获得Msg B的CORESET的配置信息,终端设备在这组CORESET上检测Msg B。终端设备检测到RAR消息,该RAR消息的CORESET中承载的PDCCH中的DCI消息指示终端设备接收MsgB数据的时频资源配置,及其他配置信息。终端设备根据DCI消息,确定接收数据的时频资源位置及配置信息,并在确定的时频资源位置上基于配置信息指示内容接收数据。终端设备基于RAR消息中提供的上行调度信息传输Msg3,继续基于竞争的四步随机接入过程。
第六信息承载在第六资源上,所述第五信息中指示第六资源的资源位置,可以包括但不限于时域资源位置和/或频域资源位置。所述终端设备具体可以在第六资源上向网络设备发送第六信息。
在另一个具体的实现过程中,所述终端设备具体可以在第二窗口内在所述一组第五预配资源上检测所述第五信息。
其中,所述第二窗口的开始时间可以包括但不限于:

在该实现过程中,在所述终端设备发送所述第一信息之后,所述终端设备可以启动第二窗口,在该第二窗口内在所述一组第五预配资源上检测所述第五信息。
在终端设备所采用的第二窗口中的所述第二时间间隔的取值可以为0,或者还可以为大于0,本实施例对此不进行特别限定。
在一个具体的实现过程中,当所述第二时间间隔的取值为0时,所述第二窗口的开始时间则可以简化为,包括但不限于:
所述终端设备发送所述第一信息之后;或者

具体来说,所述终端设备具体可以接收网络设备发送的下列信息中的至少一项,用以指示所述第二窗口的大小:

高层信令;以及
物理层信令。
例如,具体可以采用系统广播消息中现有的主信息块(Master Information Block,MIB)或系统信息块(System Information Block,SIB)携带指示信息,用以指示所述第二窗口的大小,或者还可以增加新的SIB携带指示信息,用以指示所述第二窗口的大小。
或者,再例如,所述高层信令可以是无线物理资源控制(Radio Resource Control,RRC)消息,具体可以通过RRC消息中的信息元素(Information Element,IE)携带指示信息,用以指示所述第二窗口的大小,所述RRC消息可以为现有技术中的RRC消息,例如,RRC连接重配置(RRC CONNECTION RECONFIGURATION)消息等,本实施例对此不进行限定,通过对已有的RRC消息的IE进行扩展携带指示信息,用以指示所述第二窗口的大小,或者所述RRC消息也可以为不同于现有技术中已有的RRC消息。
或者,再例如,所述高层信令可以是媒体访问控制(Media Access Control,MAC)控制元素(Control Element,CE)消息,具体还可以通过增加新的MAC CE消息携带指示信息,用以指示所述第二窗口的大小。
或者,再例如,所述物理层信令可以是下行控制信息(Downlink control information,DCI),具体可以通过DCI携带指示信息,用以指示所述第二窗口的大小。
在该过程中,出现了所述终端设备在第一窗口内,检测Msg B,在第二窗口内,检测第五信息的情况,此时,存在以下两种情况:
例如,若所述终端设备检测到所述第三信息,所述终端设备则可以停止在所述第二窗口内在所述一组第五预配资源上检测所述第五信息。
终端设备在第一窗口内检测到所述第三信息时对应的情况是:终端设备向网络设备发送Msg A的过程中(如发送第一信息之后,第二信息还未发送),或者,发送Msg A之后,接收到的响应消息并不是四步基于竞争的随机接入过程的RAR消息,而是两步基于竞争的随机接入过程的Msg B,此时,两步基于竞争的随机接入过程正常进行。在上述情况下,终端设备则可以停止在第一窗口内在所述一组第三预配资源上继续检测Msg B,也就是终端设备停止在第一窗口内在一组第三预配资源上继续检测是否有第三序列加扰的第三信道,以及终端设备则可以停止在第二窗口内在所述一组第五预配资源上检测RAR消息,也就是终端设备停止在第一窗口内在一组第五预配资源上检测是否有第五序列加扰的第五信道。
或者,再例如,若所述终端设备检测到所述第五信息,所述终端设备则可以不执行所述终端设备在第二资源上发送第二信息的操作,或者所述终端设备停止在所述第一窗口内在所述一组第三预配资源上检测所述第三信息;以及所述终端设备在第六资源上发送第六信息。
第六信息承载在第六资源上,所述第五信息中指示第六资源的资源位置,可以包括但不限于时域资源位置和/或频域资源位置。所述终端设备具体可以在第六资源上向网络设备发送第六信息。
终端设备在第二窗口内检测到RAR消息时对应的情况有两种:
一种情况是:终端设备向网络设备发送Msg A之后,接收到的响应消息并不是两步基于竞争的随机接入过程的Msg B,而是四步基于竞争的随机接入过程的RAR消息,此时,两步基于竞争的随机接入过程回退为四步基于竞争的随机接入过程。在上述情况下,终端设备则可以停止在第一窗口内在所述一组第五预配资源上继续检测RAR消息,也就是终端设备停止在第一窗口内在一组第五预配资源上继续检测是否有第五序列加扰的第五信道,以及终端设备则可以停止在第一窗口内在所 述一组第三预配资源上继续检测Msg B,也就是终端设备停止在第一窗口内在一组第三预配资源上继续检测是否有第三序列加扰的第三信道。在终端设备检测到RAR消息之后,在RAR消息中获得Msg3发送的第六资源的资源位置的指示,以及发送方式,终端设备在所指示的资源位置上,利用所指示的发送方式,发送第六信息,如图2J所示。终端设备获得CORESET的配置信息,该配置信息指示一组周期出现的CORESET位置,终端设备在这组CORESET上检测RAR消息。其中,RAR消息中指示Msg3发送所需要的资源信息。终端设备根据RAR消息,确定Msg 3的发送资源及方式。CORESET中承载的PDCCH中的DCI消息指示终端设备接收数据的时频资源配置,及其他配置信息。终端设备检测到RAR消息,终端设备基于RAR消息中提供的上行调度信息传输Msg3,继续基于竞争的四步随机接入过程。
另一种情况是:终端设备向网络设备发送Msg A的过程中(如发送第一信息之后,第二信息还未发送),接收到的响应消息并不是两步基于竞争的随机接入过程的Msg B,而是四步基于竞争的随机接入过程的RAR消息,此时,两步基于竞争的随机接入过程回退为四步基于竞争的随机接入过程。在上述情况下,终端设备则可以停止在第一窗口内在所述一组第五预配资源上继续检测RAR消息,也就是终端设备停止在第一窗口内在一组第五预配资源上继续检测是否有第五序列加扰的第五信道,以及终端设备则可以停止在第二资源上发送第二信息,以及停止在第一窗口内在所述一组第三预配资源上继续检测Msg B,也就是终端设备停止在第一窗口内在一组第三预配资源上继续检测是否有第三序列加扰的第三信道。在终端设备检测到RAR消息之后,在RAR消息中获得Msg3发送的第六资源的资源位置的指示,以及发送方式,终端设备在所指示的资源位置上,利用所指示的发送方式,发送第六信息,如图2K所示。终端设备获得CORESET的配置信息,该配置信息指示一组周期出现的CORESET位置,终端设备在这组CORESET上检测RAR消息。其中,RAR消息中指示Msg3发送所需要的资源信息。终端设备根据RAR消息,确定Msg 3的发送资源及方式。CORESET中承载的PDCCH中的DCI消息指示终端设备接收数据的时频资源配置,及其他配置信息。终端设备检测到RAR消息,终端设备基于RAR消息中提供的上行调度信息传输Msg 3,继续基于竞争的四步随机接入过程。
在该实现方式中,考虑到第一窗口和第二窗口在时间上有可能会发生重叠,那么,当第一窗口与第二窗口在时间上发生重叠(重叠部分称为第三窗口)时,终端设备则需要在重叠部分即第三窗口内,在所述一组第三预配资源上检测第三信息,在所述一组第五预配资源上检测第五信息。此时,存在以下两种情况:
例如,终端设备在第三窗口内检测到所述第三信息时对应的情况是:终端设备向网络设备发送Msg A之后,接收到的响应消息并不是四步基于竞争的随机接入过程的RAR消息,而是两步基于竞争的随机接入过程的Msg B,此时,两步基于竞争的随机接入过程正常进行。在上述情况下,终端设备则可以停止在第一窗口内在所述一组第三预配资源上继续检测Msg B,也就是终端设备停止在第一窗口内在一组第三预配资源上继续检测是否有第三序列加扰的第三信道,以及终端设备则可以停止在第二窗口内在所述一组第五预配资源上继续检测RAR消息,也就是终端设备停止在第二窗口内在一组第五预配资源上继续检测是否有第五序列加扰的第五信道。
或者,再例如,终端设备在第三窗口内检测到RAR消息时对应的情况是:终端设备向网络设备发送Msg A之后,接收到的响应消息并不是两步基于竞争的随机接入过程的Msg B,而是四步基于竞争的随机接入过程的RAR消息,此时,两步基于竞争的随机接入过程回退为四步基于竞争的随机接入过程。在上述情况下,终端设备则可以停止在第一窗口内在所述一组第五预配资源上继续检测RAR消息,也就是终端设备停止在第一窗口内在一组第五预配资源上继续检测是否有第五序列加扰的第五信道,以及终端设备则可以停止在第一窗口内在所述一组第三预配资源上继续检测Msg B,也就是终端设备停止在第一窗口内在一组第三预配资源上继续检测是否有第三序列加扰的第三信道。在终端设备检测到RAR消息之后,在RAR消息中获得Msg3发送的第六资源的资源位置的指示,以及发送方式,终端设备在所指示的资源位置上,利用所指示的发送方式,发送第六信息。
这样,通过在第一窗口与第二窗口在时间上发生重叠的重叠部分即第三窗口内同时检测第三信息和第五信息,并且能够相互中断,能够避免终端设备不必要的冗余发送和检测操作而导致的网络 设备和终端设备的后续行为的不确定性,提高了基于竞争的两步随机接入的性能,进一步降低了随机接入的时延开销。
可选地,在本实施例的一个可能的实现方式中,所述终端设备还可以进一步接收指示信息,用以指示是否允许所述终端设备执行所述终端设备在一组第五预配资源上检测第五信息的操作。

或者,再例如,所述高层信令可以是无线物理资源控制(Radio Resource Control,RRC)消息,具体可以通过RRC消息中的信息元素(Information Element,IE)携带指示信息,用以指示是否允许所述终端设备执行所述终端设备在一组第五预配资源上检测第五信息的操作,所述RRC消息可以为现有技术中的RRC消息,例如,RRC连接重配置(RRC CONNECTION RECONFIGURATION)消息等,本实施例对此不进行限定,通过对已有的RRC消息的IE进行扩展携带指示信息,用以指示是否允许所述终端设备执行所述终端设备在一组第五预配资源上检测第五信息的操作,或者所述RRC消息也可以为不同于现有技术中已有的RRC消息。
或者,再例如,所述高层信令可以是媒体访问控制(Media Access Control,MAC)控制元素(Control Element,CE)消息,具体还可以通过增加新的MAC CE消息携带指示信息,用以指示是否允许所述终端设备执行所述终端设备在一组第五预配资源上检测第五信息的操作。
或者,再例如,所述物理层信令可以是下行控制信息(Downlink control information,DCI),具体可以通过DCI携带指示信息,用以指示是否允许所述终端设备执行所述终端设备在一组第五预配资源上检测第五信息的操作。
在该实现方式中,所述指示信息还可以进一步用于指示所述终端设备执行所述终端设备在第一窗口内在一组第五预配资源上检测第五信息的操作,还是执行所述终端设备在第二窗口内在一组第五预配资源上检测第五信息的操作。
例如,所述指示信息中具体可以包含1比特信息,其取值为0,表示用于指示所述终端设备执行所述终端设备在第一窗口内在一组第五预配资源上检测第五信息的操作,取值为1,表示用于指示所述终端设备执行所述终端设备在第二窗口内在一组第五预配资源上检测第五信息的操作,或者还可以反过来,其取值为1,表示用于指示所述终端设备执行所述终端设备在第一窗口内在一组第五预配资源上检测第五信息的操作,取值为0,表示用于指示所述终端设备执行所述终端设备在第二窗口内在一组第五预配资源上检测第五信息的操作。
本申请提供了一种基于竞争的两步随机接入过程中Msg B的检测方案,并考虑到基于竞争的两步随机接入过程回退到基于竞争的四步随机接入过程的情况,给出了兼顾两步随机接入过程中Msg B的接收及四步随机接入过程中Msg 2接收的检测方案设计,并分析、处理了两种检测之间的关联关系,避免在两步随机接入过程中造成不必要的冗余发送和检测操作,提高了基于竞争的两步随机接入的性能,进一步降低了随机接入的时延开销。
本实施例中,通过终端设备在第一资源上发送第一信息,在第二资源上发送第二信息,进而由所述终端设备在第一窗口内在一组第三预配资源上检测第三信息,使得所述终端设备能够在第四资源上接收第四信息,这样,一次完整的随机接入流程只需要终端设备与网络设备之间进行一次信息交互,能够有效降低随机接入的时延开销,从而实现了低时延场景下终端设备的随机接入。

可选地,在本实施例的一个可能的实现方式中,所述网络设备还可以进一步在第五资源上发送第五信息。
