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,在5G***中,随机接入分为基于竞争的随机接入和基于非竞争的随机接入。其中,基于竞争的随机接入分为4个步骤。
步骤1:用户设备(UE)发送随机接入前导码(preamble),以请求随机接入。
步骤2:基站反馈随机接入响应消息(Random Access Response,RAR)。UE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。
步骤3:UE发送随机响应消息3。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)。
步骤4:基站反馈随机响应消息4。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)。
在5G非授权频谱独立组网设计上,需要遵循LBT(监听避让)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,将放弃本次传输,继续监听下一个时频资源,这样则导致时延增加,影响随机接入的效率。因此,一种可能的方案是将基于竞争的随机接入改为2步实现,例如,将步骤1和步骤3中的信息合并为一个消息发送。将步骤2和步骤4中的信息合并为一个消息发送。这样,基站可能既支持2步竞争随机接入又支持4步竞争随机接入,或者仅支持4步竞争随机接入。这就带来一个问题,UE不知道基站支持哪种竞争随机接入,不知道应该采用哪种竞争随机接入过程。
为解决上述问题,本实施例对***消息进行了改进,增加了指示信息,用于指示支持2步竞争随机接入或支持4步竞争随机接入。
图1是根据一示例性实施例示出的一种传输随机接入指示信息的方法的流程图,该传输随机接入指示信息的方法用于基站等接入网设备。如图1所示,该方法包括以下步骤101-102。
在步骤101中,生成关于随机接入的指示信息;指示信息用于指示支持2步竞争随机接入或支持4步竞争随机接入。
在步骤102中,向用户设备广播***消息,所述***消息包括所述指示信息。
本实施例对***消息进行了改进,增加了指示信息,用于指示支持2步竞争随机接入或支持4步竞争随机接入。指示信息表示支持2步竞争随机接入时,说明基站既支持2步竞争随机接入又支持4步竞争随机接入。指示信息表示支持4步竞争随机接入时,说明基站仅支持4步竞争随机接入。
UE可能既支持2步竞争随机接入又支持4步竞争随机接入。当指示信息表示支持2步竞争随机接入时,UE可以优先采用2步竞争随机接入。当指示信息表示支持4步竞争随机接入时,UE只能采用4步竞争随机接入。如果UE仅支持4步竞争随机接入,那么无论指示信息是什么,均只能采用4步竞争随机接入。
基站既支持2步竞争随机接入又支持4步竞争随机接入时,基站可以先采用2步竞争随机接入方式来解析收到的消息,如果解析成功,则确定UE采用的是2步竞争随机接入方式。如果解析不成功,则确定UE采用的是4步竞争随机接入方式,再采用4步竞争随机接入方式来解析收到的消息。当然,基站也可以先采用4步竞争随机接入方式来解析收到的消息。在本实施例中不做限定。
指示信息可以通过多种方式来体现,参见下面的实施例。
在一个实施例中,所述***消息包括用于承载所述指示信息的指示位,所述指示位占用1比特。指示位仅占用1比特位,占用的网络资源较少。
所述指示位取值为1时,表示支持2步竞争随机接入,取值为0时,表示支持4步竞争随机接入。或者,所述指示位取值为0时,表示支持2步竞争随机接入,取值为1时,表示支持4步竞争随机接入。
UE根据指示位的取值便可获知基站支持哪种竞争随机接入。
本实施例中的***消息可以是主***信息块(MIB)或***信息块1(SIB1)。
在一个实施例中,所述***消息包括用于承载所述指示信息的指示位,所述指示位的取值为真(true)时,表示支持支持2步竞争随机接入,所述指示位的取值为假(false)时,表示支持支持4步竞争随机接入。
或者,所述指示位的取值为真(true)时,表示支持支持4步竞争随机接入,所述指示位的取值为假(false)时,表示支持支持2步竞争随机接入。
本实施例提供另一种指示位的取值方式,即指示位的取值可以是true或false。所述指示位的取值为真(true)时,表示支持支持2步竞争随机接入,所述指示位的取值为假(false)时,表示支持支持4步竞争随机接入。或者,所述指示位的取值为真(true)时,表示支持支持4步竞争随机接入,所述指示位的取值为假(false)时,表示支持支持2步竞争随机接入。
UE根据指示位的取值便可获知基站支持哪种竞争随机接入。
本实施例中的***消息可以是主***信息块(MIB)或***信息块1(SIB1)。
在一个实施例中,当所述指示信息指示支持2步竞争随机接入时,所述***消息包括指示位,当所述指示信息指示支持4步竞争随机接入时,所述***消息缺省所述指示位。
或者,当所述指示信息指示支持2步竞争随机接入时,所述***消息缺省指示位,当所述指示信息指示支持4步竞争随机接入时,所述***消息包括所述指示位。
本实施例中指示位的缺省也是一种指示信息,并且可以节省网络资源。
本实施例中的***消息可以是主***信息块(MIB)或***信息块1(SIB1)。
在一个实施例中,所述指示信息包括支持2步竞争随机接入时所需的资源配置信息和/或支持4步竞争随机接入时所需的资源配置信息。
所述***消息包括第一信息单元和/或第二信息单元,所述第一信息单元用于承载支持2步竞争随机接入时所需的资源配置信息,所述第二信息单元用于承载支持4步竞争随机接入时所需的资源配置信息。
本实施例中可以通过资源配置信息来表示指示信息。如果基站配置了2步竞争随机接入所需的资源配置信息,则表示基站支持2步竞争随机接入。如果基站只配置了4步竞争随机接入所需的资源配置信息,则表示基站只支持4步竞争随机接入。如果基站配置了2步竞争随机接入和4步竞争随机接入所需的资源配置信息,则表示基站既支持2步竞争随机接入又支持4步竞争随机接入。
本实施例不需要额外的指示位来指示,节省了网络资源。当然,本实施例也可以前面的实施例结合,即***消息包括指示位和相应的资源配置信息。
本实施例中的***消息可以是***信息块1(SIB1)。
以上介绍了基站侧的实现过程,相应的,UE侧也有所改进。下面对UE侧的实现过程进行介绍。

在一个实施例中,所述***消息包括用于承载所述指示信息的指示位,所述指示位占用1比特。
所述步骤202包括:步骤A。
在步骤A中,从所述***消息中解析出指示位,并从指示位中识别出所述指示信息。

UE根据指示位的取值便可获知基站支持哪种竞争随机接入。
所述步骤203包括:
确定指示位为1时,确定支持2步竞争随机接入;确定指示位为0时,确定支持4步竞争随机接入。
或者,确定指示位为0时,确定支持2步竞争随机接入;确定指示位为1时,确定支持4步竞争随机接入。
本实施例中的***消息可以是主***信息块(MIB)或***信息块1(SIB1)。

所述步骤203包括:
所述指示位的取值为真true时,确定所述指示信息表示支持2步竞争随机接入,所述指示位的取值为假false时,确定所述指示信息表示支持4步竞争随机接入。
或者,所述指示位的取值为真true时,确定所述指示信息表示支持4步竞争随机接入,所述指示位的取值为假false时,确定所述指示信息表示支持2步竞争随机接入。
本实施例中的***消息可以是主***信息块(MIB)或***信息块1(SIB1)。
在一个实施例中,指示信息需要指示支持2步竞争随机接入还是支持4步竞争随机接入这两种情况,本实施例可以采用指示位是否缺省来表示这两种情况,参见下面的实施例。
在一个实施例中,当所述指示信息指示支持2步竞争随机接入时,所述***消息包括所述指示位。
当所述指示信息指示支持4步竞争随机接入时,所述***消息缺省所述指示位。
所述步骤203包括:步骤B1-步骤B2。

本实施例中的***消息可以是主***信息块(MIB)或***信息块1(SIB1)。
本实施例中UE可以根据指示位是否缺省来确定指示信息。如果指示位缺省还是不缺省,则***消息的长度会发生变化,或者说***消息中用于承载该指示位的信息单元的长度会发生变化。UE可以根据***消息或信息单元的长度来确定指示位是否缺省。如果指示位不缺省, 则指示位的值可以是0、1、true或false。指示位的任何取值都指示的是一种情况,要么支持2步竞争随机接入,要么支持4步竞争随机接入,只能指示其中一种。
本实施例中指示位缺省时可以进一步节省网络资源。

本实施例中可以通过配置的资源配置消息来表示指示信息。如果UE解析出2步竞争随机接入所需的资源配置信息,则表示基站支持2步竞争随机接入。如果UE只解析出4步竞争随机接入所需的资源配置信息,则表示基站只支持4步竞争随机接入。如果UE解析出2步竞争随机接入和4步竞争随机接入所需的资源配置信息,则表示基站既支持2步竞争随机接入又支持4步竞争随机接入。
UE解析出资源配置信息后,便可以根据实际情况应用相应的资源
本实施例不需要额外的指示位来指示,节省了网络资源。当然,本实施例也可以前面的实施例结合,即***消息包括指示位和相应的资源配置信息。
本实施例提供了多种指示方式,***为基站与UE配置相同的指示方式即可。
