具体实施方式
下面将结合本公开中的附图,对本公开的一些实施例中的技术方案进行清楚、完整地描述。显然,所描述的实施例是本公开的一部分实施例,而不 是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
本公开提供的随机接入的处理方法、用户终端及网络侧设备可以解决随机接入信号的发送范围和发送距离不能兼顾的问题。
参见图1,图1是本公开的一些实施例提供的随机接入的处理方法的流程图,该随机接入的处理方法主要应用在移动终端中,用于对随机接入过程进行控制。
如图1所示,该方法包括以下步骤101-103。
步骤101、向网络侧设备发送至少两个随机接入信号。
该步骤中,在用户终端每一次进行随机接入过程中,均会向网络侧设备发送至少两个随机接入信号。发送至少两个随机接入信号的波束为窄波束或者与窄波束的功能相同的波束。在图1的实施例中,可以通过波束扫描的方式连续发送至少两个随机接入信号,可以预先配置波束扫描的方式,以及加载随机接入信号的波束。具体的,随机接入信号的数量可以根据实际需要进行设置,在此不做进一步的限定。
步骤102、根据第一配置信息确定至少一个第一目标随机接入信号对应的随机接入响应标识信息,所述至少一个第一目标随机接入信号为所述至少两个随机接入信号中的至少一个随机接入信号。
该步骤中,每一第一目标随机接入信号均对应有一个随机接入响应标识信息。上述第一配置信息为协议预先设定的配置信息或者为网络侧设备发送的配置信息,即通过协议预先约定第一配置信息或者网络侧设备指示第一配置信息。此外,还可以是协议预先设定部分配置信息,通过网络侧设备指示一部分配置信息。
在图1的实施例中,上述第一目标随机接入信号的数量可以为1个,也可以为多个,在此不做进一步的限定。
例如,当第一目标随机接入信号为一个时,可以为发送的至少两个随机接入信号中的首个随机接入信号,也可以为末个随机接入信号,还可以是中间的任意一个随机接入信号。
当第一目标随机接入信号为至少两个时,可以包括所有发送的随机接入 信号,也可仅包含部分随机接入信号。
其次,确定第一目标随机接入信号对应的随机接入响应标识信息的时间点可以根据事实需要进行设置。例如,可以在发送随机接入信号之前确定每一第一目标随机接入信号的随机接入响应标识信息;也可以是在发送第一目标随机接入信号后,确定该第一目标随机接入信号的随机接入响应标识信息;此外还可以是在发送所有的随机接入信号后,统一确定所有的第一目标随机接入信号。
步骤103、根据所述随机接入响应标识信息,在至少一个第二目标随机接入信号对应的随机接入响应窗口接收随机接入响应信息,所述至少一个第二目标随机接入信号包括所述至少两个随机接入信号中的至少一个随机接入信号。
该步骤中,上述至少一个第二目标随机接入信号可以包括一个或者多个第一目标随机接入信号,当然还可以包括其他的随机接入信号,例如通过其他方式(该其他方式可以根据实际需要进行设置,例如可以根据其他的配置信息确定,或者直接由网络侧设备指示)获得的随机接入响应标识信息对应的随机接入信号。并且,每一第二目标随机接入信号对应一随机接入响应窗口。
通常的,上述至少一个第二目标随机接入信号为至少一个第一目标随机接入信号的子集或全集。
在图1的实施例中,根据确定获得的随机接入响应标识信息,可以在对应的窗口内接收网络侧设备发送的随机接入响应信息。具体的,不同的随机接入,对应的随机接入响应信息的内容不同。例如,针对非竞争随机接入,在Msg2中接收到的随机接入响应信息包括:Msg1标识信息、上行定时提前量信息(Timing Advance Command)、上行发送授权信息(UL Grant)、回退信息(Backoff Indicator)和临时终端标识信息(Temporary C-RNTI)。针对竞争随机接入在Msg2中接收到的随机接入响应信息至少包括定时提前量信息和针对Msg3的UL grant。
用户终端在接收到网络侧设备发送的随机接入响应信息后,所执行的操作可以根据实际需要进行设置,在此不做进一步的限定。
这样,本公开的一些实施例中,通过向网络侧设备发送至少两个随机接入信号;根据第一配置信息确定至少一个第一目标随机接入信号对应的随机接入响应标识信息,所述至少一个第一目标随机接入信号为所述至少两个随机接入信号中的至少一个随机接入信号;根据所述随机接入响应标识信息,在至少一个第二目标随机接入信号对应的随机接入响应窗口接收随机接入响应信息,所述至少一个第二目标随机接入信号包括所述至少两个随机接入信号中的至少一个随机接入信号。由于在本公开的一些实施例中,实现了至少两个随机接入信号的发送,以及随机接入响应信息的接收,因此可以采用多个波束发送/接收不同的随机接入信号,从而可以同时满足对随机接入信号的发送范围和发送距离的需求。
可选的,上述第一配置信息的内容可以根据实际需要进行设置,例如,上述第一配置信息可以包括每一所述第一目标随机接入信号对应的第一位置信息。其中,上述所述第一位置信息可以包括时域、频域、码域和空域中的至少一项。
具体的,上述时域、频域、码域和空域可以为具体的位置信息,也可以为具体位置信息对应的标识信息。例如可以为时域位置信息或时域标识,频域位置信息或频域标识,码域位置信息或码域标识,空域位置信息或空域标识。
进一步的,上述第一配置信息还包括位置偏移信息、随机接入响应标识的数量和随机接入响应标识偏移量。其中,位置偏移信息可以包括时域偏移量、频域偏移量、码域偏移量和空域偏移量中的至少一项。在图1的实施例中,上述时域偏移量、频域偏移量、码域偏移量和空域偏移量可以为整数,也可以为非整数,在此不做进一步的限定。所属领域技术人员可以理解,所述波束可以以信道状态信息参考信号(Channel State Information-Reference Signal,简称CSI-RS)、或同步信号块(Synchronous Signal Block,简称SSB)、或CSI-RS和SSB的组合来标识。
在图1的实施例中,每一第一目标随机接入信号对应有一个随机接入响应标识信息,对每一第一目标随机接入信号对应的随机接入响应标识信息的确定方式可以根据实际需要进行设置,以下通过一具体实例进行详细说明:
当所述位置偏移信息包括时域偏移量、频域偏移量、码域偏移量和空域偏移量时,上述步骤102包括:根据第一公式确定每一第一目标随机接入信号对应的随机接入响应标识信息ID;其中,所述第一公式为:ID=offset1*t_id+offset2*f_id+offset3*c_id+offset4*s_id+offset5,其中,offset1为当前确定的第一目标随机接入信号的时域偏移量,offset2为当前确定的第一目标随机接入信号的频域偏移量,offset3为当前确定的第一目标随机接入信号的码域偏移量,offset4为当前确定的第一目标随机接入信号的空域偏移量,offset5为当前确定的第一目标随机接入信号的随机接入响应标识偏移量,t_id为当前确定的第一目标随机接入信号的时域,f_id为当前确定的第一目标随机接入信号的频域,c_id为当前确定的第一目标随机接入信号的码域,s_id为当前确定的第一目标随机接入信号的空域。
其中,上述当前确定的第一目标随机接入信号可以为首个发送的随机接入信号,也可以为末个发送的随机接入信号,还可以是中间任意一个随机接入信号。在图1的实施例中,每一第一目标随机接入信号均有对应的第一位置信息以及位置偏移信息,根据第一位置信息和位置偏移信息即可确定获得对应的第一目标随机接入信号的随机接入响应标识信息。应当说明的是,当某一偏移量为0时,可以不用进行确定,从而降低确定的难度。
然后根据该随机接入响应标识信息在相应的随机接入响应窗口内,接收网络侧设备发送的随机接入响应信息即可。对于随机接入响应窗口的确定方式可以根据实际需要进行设置,以下对此进行详细说明。
具体的,参照图2,在上述步骤103之前,所述方法还包括步骤104。
步骤104、根据第二配置信息确定所述至少一个第二目标随机接入信号对应的随机接入响应窗口的位置。
其中,上述第二配置信息可以根据实际需要进行设置,例如,上述第二配置信息包括每一所述第二目标随机接入信号对应的第二位置信息。该第二位置信息可以包括时域、频域、码域和空域中的至少一项。
在图2的实施例中,对于需要确定随机接入响应窗口的随机接入信号,采用重新配置的方式。应理解,当第二目标随机接入信号的集合等于第一目标随机接入信号的集合时,可以根据第一目标随机接入信号的第一位置信息 进行随机接入响应窗口确定。
进一步的,上述第二配置信息还包括随机接入响应窗口的数量、随机接入窗口的起始位置偏移量和随机接入响应窗口的窗长。
具体的,每一第二目标随机接入信号均有对应的随机接入响应窗口,例如,在发送一个第二目标随机接入信号时,便启动一个对应的随机接入窗口监听随机接入响应信息。
在图2的实施例中,所述步骤104可以包括:根据第二公式确定每一第二目标随机接入信号对应的随机接入响应窗口的起始位置window_start;所述第二公式为:window_start=n_config+offset6,其中,n_config为当前确定的第二目标随机接入信号的第二位置信息,offset6为当前确定的随机接入响应窗口的起始位置偏移量;以及根据当前确定的随机接入响应窗口的起始位置和窗长确定随机接入响应窗口的位置。
在图2的实施例中,上述第二目标随机接入信号的数量可以为1个,也可以为多个,在此不做进一步的限定。
例如,当第二目标随机接入信号为一个时,可以为发送的至少两个随机接入信号中的首个随机接入信号,也可以为末个随机接入信号,还可以是中间的任意一个随机接入信号。
当第二目标随机接入信号为至少两个时,可以包括所有发送的随机接入信号,也可仅包含部分随机接入信号。
应当说明的是,用户终端获取上述第一配置信息和第二配置信息的方式可以根据实际需要进行设置,在图2的实施例中,上述第二配置信息为协议预先设定的配置信息或者为网络侧设备发送的配置信息;上述第一配置信息为协议预先设定的配置信息或者为网络侧设备发送的配置信息。
进一步的,参照图3,在图3的实施例中,在上述步骤103之后,所述方法还包括步骤105。
步骤105、将满足预设条件的随机接入响应信息设定为目标配置信息。
该步骤中,上述预设条件可以根据实际需要进行设置。例如,在本实施例中,上述预设条件可以包括以下任一项:首个接收到的随机接入响应信息;末个接收到的随机接入响应信息;在接收到的随机接入响应信息中,随机选 择的随机接入响应信息;接收到的随机接入响应信息中,包含随机接入指示信号的随机接入响应信息;接收到的随机接入响应信息中,首个包含随机接入指示信号的随机接入响应信息;接收到的随机接入响应信息中,末个包含随机接入指示信号的随机接入响应信息;以及在接收到包含随机接入指示信号的随机接入响应信息中,随机选择的随机接入响应信息。
进一步的,本公开还提供一种随机接入的处理方法。该随机接入的处理方法应用于网络侧设备,用于对随机接入过程进行控制。参照图4,该随机接入的处理方法包括步骤401-402。
步骤401、向用户终端发送第一配置信息,所述第一配置信息用于供用户终端确定至少一个第一目标随机接入信号对应的随机接入响应标识信息,所述至少一个第一目标随机接入信号为至少两个随机接入信号中的至少一个随机接入信号,所述至少两个随机接入信号为用户终端按照预设的配置发送的随机接入信号。
该步骤中,在用户终端每一次进行随机接入过程中,均会向网络侧设备发送至少两个随机接入信号。发送至少两个随机接入信号的波束为窄波束或者与窄波束的功能相同的波束。在图4的实施例中,可以通过波束扫描的方式连续发送至少两个随机接入信号,可以预先配置波束扫描的方式,以及加载随机接入信号的波束。具体的,随机接入信号的数量可以根据实际需要进行设置,在此不做进一步的限定。
网络侧设备针对随机接入信号确定需要计算随机接入响应标识信息的第一目标随机接入信号,并向用户终端发送第一配置信息,以供用户终端根据第一配置信息计算确定每一第一目标随机接入信号的随机接入响应标识信息。
可以理解的是,网络侧设备发送第一配置信息的方式可以根据实际需要进行设置,例如可以通过广播方式的发送第一配置信息,还可以通过用户终端的专属信息发送第一配置信息,还可以在PDCCH(Physical Downlink Control Channel,物理下行控制信道)上发送第一配置信息。
步骤402、在接收到随机接入信号时,向所述用户终端发送所述随机接入信号对应的随机接入响应信息。
该步骤中,网络侧设备可以仅发送上述第一目标随机接入信号的随机接 入响应信息,也可以发送所有随机接入信号的随机接入响应信息,其中每一随机接收信号对应一随机接入响应信息。
