具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
相关技术中,业内近期对5G(第5代移动通信)非授权频谱进行了立项研究,提出支持5G非授权小区单独组网的方案。在5G非授权频谱独立组网设计上,需要遵循LBT(先听后说)机制。即,在随机接入过程中,无论上下行,在发送消息之前,都需要监听信道。如果没有可用的时频资源,则导致时延增加,影响随机接入的效率。
为解决上述问题,本实施例为随机接入的上下行传输在多个载波上配置时频资源,当至少有一个载波上的时频资源空闲,便可完成该次传输,提高了传输几率,减少了时延,有助于提高随机接入的效率。
图1是根据一示例性实施例示出的一种随机接入的处理方法的流程图,该随机接入的处理方法用于终端中,其中,终端可以是移动电话,计算机,数字广播终端,消息收发设备,游戏控制台,平板设备,医疗设备,健身设备,个人数字助理等。如图1所示,该方法包括以下步骤101-102。
在步骤101中,在预先配置的第一载波组中的至少一个载波上,监听用于传输物理随机接入信道(PRACH)的时频资源是否空闲;所述第一载波组至少包括两个载波;
在步骤102中,当存在空闲的PRACH的时频资源时,在所述空闲的PRACH的时频资源上发送随机接入前导码,以请求随机接入。
当不存在空闲的PRACH的时频资源时,本次放弃发送随机接入前导码(preamble),可以继续步骤101。
本实施例为PRACH在多个载波上配置了时频资源,用户设备可以监听第一载波组中的部分载波,如至少监听一个载波,可以采用随机等方式从第一载波组中选择部分载波监听。通过这种选择机制,可以增大监听到空闲的时频资源的几率,有助于提高随机接入的效率。
或者,用户设备可以监听第一载波组中的所有载波,当至少有一个载波上的时频资源空闲时,便可完成preamble的发送,实现随机接入请求。提高了发送preamble的几率,减少了时延,有助于提高随机接入的效率。
用户设备可以同时监听多个载波上PRACH的时频资源是否空闲。当存在多个载波上PRACH的时频资源空闲时,按照预设的第一顺序,选择一个载波上PRACH的时频资源传输preamble。
或者,按照预设的第二顺序,先监听第一载波组中的第一载波上PRACH的时频资源是否空闲,如果空闲,则使用第一载波上PRACH的时频资源传输preamble,不再继续监听第一载波组中的其它载波。如果第一载波上PRACH的时频资源不空闲,则按照第二顺序,监听第一载波组中的第二载波,以此类推。
第一顺序和第二顺序可以相同或不同。顺序可以是按照频段由高到低或由低到高等顺序。各种顺序均可适用于本实施例。
本实施例既遵循了LBT原则,又提高了随机接入请求的效率,减少了时延。
在一个实施例中,在监听用于传输物理随机接入信道PRACH的时频资源是否空闲之前,所述方法还包括:步骤A。
在步骤A中,接收基站侧发送的第一系统信息块,所述第一系统信息块包括所述第一载波组的指示信息和PRACH在所述第一载波组中至少一个载波上时频资源的指示信息。
本实施例中基站预先向用户设备发送第一系统信息块,以便配置PRACH在多个载波上的时频资源。该第一系统信息块可以是主系统信息(Master Information Block,MIB),系统信息块(System Information Block,SIB)2或其它系统信息块。基站可以在用户设备处于空闲态或非激活态时发送,也可以在需要进行随机接入时发送。
在一个实施例中,所述方法还包括:步骤B1-步骤B3。
在步骤B1中,在预先配置的第二载波组中的至少一个载波上,监听基站侧发送的随机接入响应消息(Random Access Technology,RAR);所述第二载波组至少包括两个载波。
在步骤B2中,在所述第二载波组中的载波上接收RAR。
在步骤B3中,利用随机接入无线网络临时标识(Random Access Radio Network Temporary Identifier,RA-RNTI)对所述RAR进行解码,其中,所述RA-RNTI是根据所述空闲的PRACH的时频资源和所述空闲的PRACH的时频资源所在的载波确定的。
本实施例为RAR在多个载波上配置时频资源,以便提高发送RAR几率。因此,用户设备 需要在多个载波上监听RAR,以便接收RAR。
并且,本实施例中的RA-RNTI是根据所述空闲的PRACH的时频资源和所述空闲的PRACH的时频资源(发送preamble的时频资源)所在的载波确定的。这样,可以有更多的RA-RNTI,使更多的用户设备同时实现随机接入,减少冲突,提高随机接入的成功率。其中,基站也会依据所述RA-RNTI对所述RAR进行编码。
在一个实施例中,在监听基站侧发送的随机接入响应消息(RAR)之前,所述方法还包括:步骤C。
在步骤C中,接收基站侧发送的第二系统信息块,所述第二系统信息块包括所述第二载波组的指示信息。
本实施例中基站预先向用户设备发送第二系统信息块,以便配置RAR在多个载波上的时频资源。该第二系统信息块可以是MIB、系统信息块(System Information Block,SIB)2或其它系统信息块。基站可以在用户设备处于空闲态或非激活态时发送,也可以在需要进行随机接入时发送。
第二系统信息块与第一系统信息块可以是同一个系统信息块,也可以是不同的系统信息块。
本实施例中,第二系统信息块可以不包括RAR的时频资源的指示信息,用户设备监听第二载波组即可。
在一个实施例中,所述第二系统信息块还包括RAR的时频资源的指示信息。
本实施例中,所述第二系统信息块还包括RAR的时频资源的指示信息。这样,用户设备可以更准确的监听RAR。
在一个实施例中,所述RAR包括随机响应消息(Message,Msg)3在所述第三载波组中的至少一个载波上的时频资源的指示信息。
本实施例利用RAR来通知用户设备Msg3的时频资源的指示信息,没有增加额外的通知消息,方便用户设备及时获知Msg3的时频资源。
并且,第三载波组至少包括两个载波,与第一载波组可以是完全相同的载波或存在不同的载波。如果第三载波组与第一载波组是完全相同的载波,那么RAR可以不包括第三载波组。
在一个实施例中,所述方法还包括:步骤D1-步骤D2。
在步骤D1中,在所述第三载波组中的至少一个载波上,监听用于传输随机响应消息3的时频资源是否空闲。
在步骤D2中,当存在空闲的随机响应消息3的时频资源时,在所述空闲的随机响应消息3的时频资源上发送随机响应消息3。
当不存在空闲的随机响应消息3的时频资源时,本次放弃发送随机响应消息3,可以继续步骤D1或步骤101。
本实施例步骤D1的监听过程可以参考步骤101的监听过程,可以监听第三载波组中的部分载波或全部载波。可以同时监听多个载波,也可以按照预设的顺序监听各个载波。
随机响应消息3可以包括临时小区无线网络临时标识(Temporary Cell Radio Network Temporary Identifier,TC-RNTI)。
本实施例为随机响应消息3在多个载波上配置了时频资源,当至少有一个载波上的时频资源空闲时,便可完成随机响应消息3的发送,提高了发送随机响应消息3的几率,减少了时延,有助于提高随机接入的效率。
在一个实施例中,所述方法还包括:步骤E1-步骤E2。
在步骤E1中,在预先配置的第四载波组中的至少一个载波上,监听基站侧发送的随机响应消息4。
在步骤E2中,在所述第四载波组中的载波上接收随机响应消息4,所述随机响应消息4包括小区无线网络临时标识(Cell Radio Network Temporary Identifier,C-RNTI)。
本实施例为随机响应消息4在多个载波上配置时频资源,以便提高发送RAR几率。因此,用户设备需要在多个载波上监听随机响应消息4,以便接收随机响应消息4。
第四载波组至少包括两个载波,与第二载波组可以是完全相同的载波或存在不同的载波。
本实施例中基站预先向用户设备发送第三系统信息块,以便配置随机响应消息4在多个载波上的时频资源。该第三系统信息块可以是MIB、系统信息块(System Information Block,SIB)2或其它系统信息块。基站可以在用户设备处于空闲态或非激活态时发送,也可以在需要进行随机接入时发送。
第三系统信息块与第一、二系统信息块可以是同一个系统信息块,也可以是不同的系统信息块。
或者,RAR包括随机响应消息4在多个载波上的时频资源的指示信息。
如果第四载波组与第二载波组是完全相同的载波,那么RAR可以不包括第四载波组,或者不需要发送第三系统信息块。
下面通过几个实施例详细介绍实现过程。
图2是根据一示例性实施例示出的一种随机接入的处理方法的流程图,该随机接入的处理方法用于终端中,其中,终端可以是移动电话,计算机,数字广播终端,消息收发设备,游戏控制台,平板设备,医疗设备,健身设备,个人数字助理等。如图2所示,该方法包括以下步骤201-205。

在步骤202中,当存在空闲的PRACH的时频资源时,在所述空闲的PRACH的时频资源上发送随机接入前导码,以请求随机接入。
当不存在空闲的PRACH的时频资源时,本次放弃发送随机接入前导码(preamble),可以继续步骤201。

在步骤205中,利用RA-RNTI对所述RAR进行解码,其中,所述RA-RNTI是根据所述空闲的PRACH的时频资源和所述空闲的PRACH的时频资源所在的载波确定的。RA-RNTI可以是基站根据所述空闲的PRACH的时频资源和所述空闲的PRACH的时频资源所在的载波为用户设备配置的。

在步骤304中,在所述第二载波组中的载波上接收RAR。
在步骤305中,利用RA-RNTI对所述RAR进行解码,其中,所述RA-RNTI是根据所述空闲的PRACH的时频资源和所述空闲的PRACH的时频资源所在的载波确定的。RA-RNTI可以是用户设备根据所述空闲的PRACH的时频资源和所述空闲的PRACH的时频资源所在的载波自行确定的。
在步骤306中,在所述第三载波组中的至少一个载波上,监听用于传输随机响应消息3的时频资源是否空闲。
在步骤307中,当存在空闲的随机响应消息3的时频资源时,在所述空闲的随机响应消息3的时频资源上发送随机响应消息3。

以上是用户设备侧的实现过程,相应的,基站侧也有所改进,下面介绍基站侧的实现过程。
图4是根据一示例性实施例示出的一种随机接入的处理方法的流程图,该随机接入的处理方法用于基站等接入设备。如图4所示,该方法包括以下步骤401-403。
在步骤401中,在预先配置的第一载波组中的载波上,接收用户设备通过PRACH时频资源的发送的随机接入前导码,以获得随机接入请求;所述第一载波组至少包括两个载波。
在步骤402中,在预先配置的第二载波组中的至少一个载波上,监听RAR的时频资源是否空闲。
在步骤403中,当存在空闲的RAR的时频资源时,在所述空闲的RAR的时频资源上发送RAR。
当不存在空闲的RAR的时频资源时,本次放弃发送RAR,可以继续步骤402或步骤401。
本实施例中基站监听多个载波,以便接收用户设备发送的随机接入前导码。
基站为RAR在多个载波上配置了时频资源,基站可以监听第二载波组中的部分载波,如至少监听一个载波,可以采用随机等方式从第二载波组中选择部分载波监听。通过这种选择机制,可以增大监听到空闲的时频资源的几率,有助于提高随机接入的效率。
或者,基站可以监听第二载波组中的所有载波,当至少有一个载波上的时频资源空闲时,便可完成RAR的发送,提高了发送RAR的几率,减少了时延,有助于提高随机接入的效率。
基站可以同时监听多个载波上RAR的时频资源是否空闲。当存在多个载波上RAR的时频资源空闲时,按照预设的第三顺序,选择一个载波上RAR的时频资源传输RAR。
或者,按照预设的第四顺序,先监听第二载波组中的第一载波上RAR的时频资源是否空闲,如果空闲,则使用第一载波上RAR的时频资源传输RAR,不再继续监听第二载波组中的其它载波。如果第一载波上RAR的时频资源不空闲,则按照第四顺序,监听第二载波组中的第二载波,以此类推。
第三顺序和第四顺序可以相同或不同。顺序可以是按照频段由高到低或由低到高等顺序。各种顺序均可适用于本实施例。
本实施例既遵循了LBT原则,又提高了随机接入请求的效率,减少了时延。

本实施例为随机响应消息4在多个载波上配置时频资源,以便提高发送RAR几率。因此,用户设备需要在多个载波上监听随机响应消息4,以便接收随机响应消息4。
第四载波组至少包括两个载波,与第二载波组可以是完全相同的载波或存在不同的载波。
本实施例中基站预先向用户设备发送第三系统信息块,以便配置随机响应消息4在多个载波上的时频资源。该第三系统信息块可以是MIB、系统信息块(System Information Block,SIB)2或其它系统信息块。基站可以在用户设备处于空闲态或非激活态时发送,也可以在需要进行随机接入时发送。
第三系统信息块与第一、二系统信息块可以是同一个系统信息块,也可以是不同的系统信息块。
或者,RAR包括随机响应消息4在多个载波上的时频资源的指示信息。
如果第四载波组与第二载波组是完全相同的载波,那么RAR可以不包括第四载波组,或者不需要发送第三系统信息块。
