技术领域
本公开涉及通信领域,尤其涉及一种MPDU的传输方法、用户侧设备和网络侧设备。
背景技术
由于网络侧会通过波束扫描的方式发送下行信号,因此终端在发起上行随机接入过程的时候,网络会给终端配置每个下行波束对应的上行随机接入资源,即物理随机接入信道(Physical Random Access Channel,PRACH)资源,而该下行波束对应的参考信号包括CSI-RS和/或SS block。
终端会在选定对应的下行接收波束后,在该波束对应的上行随机接入资源发送msg1,即物理随机接入信道(Physical Random Access Channel,PRACH)。而网络侧则会在接收到该UE的msg1后,在该随机接入资源对应的下行波束上发送msg2,即RAR)。终端会在配置的RAR窗口内,去对应的下行波束上监测mgs1对应的RAR消息。
现有的RAR消息格式较为单一。在现有的RAR消息中,主要携带定时命令(TA command)、上行链路授权(UL grant)和临时的小区无线网络临时标识(Temporary Cell Radio Network Temmporary Identify,T-C-RNTI)。

具体实施方式
为了使本技术领域的人员更好地理解本公开中的技术方案,下面将结合本公开的一些实施例中的附图,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,所描述的实施例仅仅是本公开一部分实施例,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,都应当属于本公开保护的范围。
本公开提供一种MPDU的传输方法、用户侧设备和网络侧设备,以使得网络侧设备和用户侧设备的消息交互更灵活方便。
本公开的技术方案,可以应用于各种通信系统,例如:全球移动通讯系统(GSM,Global System of Mobile communication),码分多址(CDMA,Code Division Multiple Access)系统,宽带码分多址(WCDMA,Wideband Code Division Multiple Access),通用分组无线业务(GPRS,General Packet Radio  Service),长期演进(LTE,Long Term Evolution)/增强长期演进(LTE-A,Long Term Evolutionadvanced),NR(New Radio)等。
用户端(UE,User Equipment),也可称之为移动终端(Mobile Terminal)、移动用户设备等,可以经无线接入网(例如,RAN,Radio Access Network)与一个或多个核心网进行通信,用户设备可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。
基站,可以是GSM或CDMA中的基站(BTS,Base Transceiver Station),也可以是WCDMA中的基站(NodeB),还可以是LTE中的演进型基站(eNB或e-NodeB,evolutional Node B)及5G基站(gNB),本公开并不限定。但为描述方便,下述实施例以gNB为例进行说明。
协议数据单元(Protocol Data Unit,PDU):是指对等层次之间传递的数据单位。物理层的PDU是数据位(bit),数据链路层的PDU是数据帧(frame),网络层的PDU是数据包(packet),传输层的PDU是数据段(segment),其他更高层次的PDU是报文(message)。
MAC协议数据单元(MAC Protocol Data Unit,MPDU):在无线网络安全中,MAC服务数据单元(MAC Service Data Unit,MSDU)经过添加完整性校验MIC、分帧、添加IV、加密、添加MAC头部后,成为MPDU。
图1是本公开的一些实施例的MPDU传输方法的示意图。图1的方法由网络侧设备执行。该方法可包括步骤S101。
S101,发送MPDU,该MPDU用于指示该MPDU中一个或多个RAR消息的格式类型。
当然,应理解,在本公开的一些实施例中,在发送MPDU之前,该方法还包括:生成该MPDU。
本公开的一些实施例中,通过发送用于指示RAR消息的格式类型的MPDU,使得网络侧设备和用户侧设备能够根据需要采用不同的RAR消息的格式,从而通过携带不同的信息达到不同的功能,使得随机接入过程适用范围更广,而且还能达到网络侧设备和用户侧设备的消息交互更灵活方便的效 果。
当然,应理解,在本公开的一些实施例中,该MPDU指示该MPDU中一个或多个RAR消息的格式类型的方式,可以通过MPDU中的指示信息直接指示,或者通过MPDU的资源位置信息间接指示。
以通过MPDU中的指示信息直接指示的方式进行举例说明。
可选地,作为一些实施例,该MPDU的至少一个第一MAC子头中包括RAR格式指示域,该RAR格式域用于指示该第一MAC子头对应的至少一个第一RAR消息的格式。
本公开的一些实施例中,通过使用MAC子头中的RAR格式指示域指示MAC子头对应的RAR消息的格式类型,从而能够支持MPDU为不同的MAC子头对应的RAR消息设置不同的格式。
可选地,在本实施例的一种实现方式中,该RAR格式域指示该至少一个第一RAR消息是否为包括响应指示域的RAR消息,该响应指示域用于指示波束失败恢复请求响应。应理解,波束失败恢复请求响应,可包括确定收到波束失败恢复请求的响应,或确定未收到波束失败恢复请求的响应。
可选地,在本实现方式中,该RAR格式域可以使用MAC子头中的预留比特位;或者,该RAR格式域可以使用MAC子头中不同于预留比特位的新增比特位。
例如,该第一MAC子头中可包括扩展比特位、类型比特位、RAR格式域、回退指示(Back off Indicator,BI)/随机接入前导标识(Random access preamble Identity,RAPID)域,该RAR格式域使用预留比特位,用于表示该第一MAC子头对应的第一RAR消息中是否包括波束失败恢复请求响应。
图2是本公开的一些实施例的MAC子头(MAC subheader)的格式示意图。如图2所示,第一MAC子头中包括扩展比特位E、类型比特位T、格式域F和BI/RAPID字段域。其中,格式域F占用预留比特位R,用于表示该第一MAC子头对应的第一RAR消息中是否包括波束失败恢复请求响应。另外,扩展比特位E\类型比特位T和BI/RAPID字段域的用途与相关技术类似。例如,扩展比特位E,也称为E字段域,用于指示MAC头部中是否还有更多的字段域,1表示后续至少有一个E/T/RAPID字段域;0表示后续为RAR 消息或间隔(padding)。类型比特位T,用于表示BI/RAPID字段域存储的是BI还是RAPID。
当然,应理解,图2的MAC子头的格式仅仅是示意性地,在实际的应用中,MAC子头的格式可能不同。
例如,该第一MAC子头中可包括扩展比特位、类型比特位、第一预留比特位、回退指示(Back off Indicator,BI)/随机接入前导标识(Random access preamble Identity,RAPID)域、RAR格式域和0个至多个第二预留比特位,该RAR格式域用于表示该第一MAC子头对应的第一RAR消息中是否包括波束失败恢复请求响应。
应理解,该RAR格式域可以包括一个或多个比特位。
可选地,在本实现方式中,当该RAR格式域指示该至少一个第一RAR消息为不包括响应指示域的RAR消息,第一RAR消息的格式可以是现有的RAR消息。
可选地,在本实现方式中,当该RAR格式域指示该至少一个第一RAR消息为包括响应指示域的RAR消息,第一RAR消息的格式中,可采用现有的RAR消息的格式,并使用预留比特位作为响应指示域。
例如,第一RAR消息的格式中,可包括响应指示域、TA COMMAND域、上行授权(Upperlink grant,UL grant)域、TEMPORARY C-RNTI域等。
图3是本公开的一些实施例的RAR消息的消息格式示意图。如图3所示,携带波束失败恢复请求响应的RAR消息的格式可包括:响应指示域Beam-R、TA COMMAND域TA-C、UL grant域UL-G和TEMPORARY C-RNTI域T-C-RNTI等。其中,响应指示域Beam-R为预留比特位。
可选地,在本实现方式中,当该RAR格式域指示该至少一个第一RAR消息为包括响应指示域的RAR消息,第一RAR消息的格式中,可采用不同于现有的RAR消息的格式,使用新增的一个或多个比特位作为响应指示域。
例如,第一RAR消息的格式中,可包括第一预留比特位、TA COMMAND域、上行授权(Upperlink grant,UL grant)域、TEMPORARY C-RNTI域、响应指示域和0个至多个第二预留比特位等。
图4是本公开的一些实施例的RAR消息的消息格式的示意图。如图4所 示,携带波束失败恢复请求响应的RAR消息的格式可包括:第一预留比特位R1、TA COMMAND域TA-C、上行授权(Upperlink grant,UL grant)域UL-G、TEMPORARY C-RNTI域T-C-RNTI、响应指示域BeamR、第二预留比特位R2等。
当然,应理解,图3和图4只是示出了携带波束失败恢复请求响应的RAR消息的部分格式,该RAR消息还可携带其它域的信息,和/或略去其中的一个或多个域,本公开的一些实施例对此不作限制。当然,应理解,该RAR消息中的各域也可能采用其它的排列方式,本公开的一些实施例对此也不做限制。
