本申请实施例涉及移动通信技术领域,具体涉及一种信息指示方法及装置、终端设备、网络设备。
背景技术
在长期演进(Long Term Evolution,LTE)系统中,随机接入过程采用的是四步随机接入过程。在新无线(New Radio,NR)系统中仍然沿用LTE系统中的四步随机接入过程。随着标准化的讨论,认为四步随机接入过程较为繁琐,会给终端的接入带来较大的时延,因此提出了两步随机接入过程。通过两步随机接入过程中的msgA传输四步随机接入过程中的msg1和msg3,通过两步随机接入过程中的msgB传输四步随机接入过程中的msg2和msg4。
在四步随机接入过程中,msgB中可以包括一个或者多个包含无线资源控制(Radio Resource Control,RRC)消息的媒体接入控制(Media Access Control,MAC)子协议数据单元(sub Protocol Data Unit,subPDU),然而,终端设备在解码msgB的MAC PDU的时候,并不知道该MAC PDU是否包含了RRC消息,更不知道该MAC PDU包含了几个RRC消息。

为便于理解本申请实施例的技术方案,以下对本申请实施例相关的技术方案进行说明。
随机接入是终端设备与网络侧建立无线连接的重要过程,通过随机接入可以与基站之间取得上行同步,申请上行资源。随机接入过程分为基于竞争的随机接入过程和基于非竞争的随机接入过程。其中,基于竞争的随机接入过程包括四步随机接入过程和两步随机接入过程,图2-1给出了四步随机接入过程的流程图,如图2-1所示,四步随机接入过程包括以下步骤:
步骤201:终端设备向基站发送msg1。
这里,终端设备向基站发送msg1具体可以通过以下过程来实现:
–终端设备确定同步信号块(Synchronization Signal Block,SSB)与PRACH资源的关系(由高层配置);
–终端设备接收一组SSB并确定其参考信号接收功率(Reference Signal Received Power,RSRP) 值,根据门限选择合适的SSB;
–终端设备基于选择的SSB和SSB与RACH资源的对应关系确定物理随机接入信道(Physical Random Access Channel,PRACH)资源;
–终端设备在PRACH时频域资源上发送前导码。
步骤202:终端设备接收基站发送的msg2。
这里,终端设备接收基站发送的msg2具体可以通过以下过程来实现:
–终端设备在发送了前导码之后的第一个物理下行控制信道(Physical Downlink Control Channel,PDCCH)时机(occasion)开启RAR窗口(ra-Response Window)并在该窗口运行期间监听PDCCH,其中,PDCCH是用RA-RNTI加扰的PDCCH。RA-RNTI跟终端设备所选PRACH时频资源有关,RA-RNTI的计算如下:
RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id
其中,s_id为PRACH资源的第一个OFDM符号的索引(0≤s_id<14);
t_id为系统帧中PRACH资源的第一个时隙的索引(0≤t_id<80);
f_id是频域中的PRACH时机的索引(0≤f_id<8);
ul_carrier_id是用于preamble index传输的上行(Uplink,UL)载波。
终端设备成功监测到RA-RNTI加扰的PDCCH之后,能够获得该PDCCH调度的PDSCH,其中包含了随机接入响应(Random Access Response,RAR)(即msg2),msg2的MAC PDU的数据格式如图2-2所示,MAC PDU包括多个MAC subPDU,分别为MAC subPDU1、MAC subPDU2、MAC subPDU3等等。其中,MAC subPDU1包含回退指示(Backoff Indication,BI),MAC subPDU1包括E/T/R/R/BI subheader,E/T/R/R/BI subheader的结构如图2-3所示。MAC subPDU2包含随机接入前导码标识(Random Access preamble ID,RAPID),MAC subPDU2包括E/T/RAPID subheader,E/T/RAPID subheader的结构如图2-4所示。其余MAC subPDU(如MAC subPDU3)包含RAPID和RAR,以MAC subPDU3为例,MAC subPDU3包括E/T/RAPID subheader和MAC RAR,E/T/RAPID subheader的结构如图2-4所示,MAC RAR的结构如图2-5所示。图2-3至图2-5中各个信息的介绍如下:
BI:回退指示信息,用于指示重传第一步消息的回退时间。
RAPID:网络响应收到的preamble index。
R:代表保留比特区域。
TAC:时间提前命令(Timing Advance Command),用于调整上行时序。
UL Grant:上行授权(Uplink Grant),用于指示上行传输Msg3的资源。
TC-RNTI:临时小区RNTI(Temporary C-RNTI),用于终端后续对发送的Msg3消息进行加扰。
步骤203:终端设备向基站发送msg3。
msg3主要用于向网络发送UE ID来解决竞争冲突。比如,如果是初始接入随机过程,则在msg3中会携带RRC层消息,也就是CCCH SDU,其中包含UE ID和连接建立请求(RRCSetupRequest);如果是RRC重建,则会携带重建立请求(RRCRestablishmentRequest)。
步骤204:终端设备接收基站发送的msg4。
msg4有两个作用,一个是用于竞争冲突解决;第二是向终端传输RRC配置消息。这里,如果终端设备收到小区无线网络临时标识(Cell-Radio Network Temporary Identifier,C-RNTI)扰码的DCI format 1_0及其对应的PDSCH,随机接入完成;如果终端收到TC-RNTI扰码的DCI format 1_0及其对应的PDSCH,并比对内容成功,随机接入完成。
两步随机接入过程正在标准化讨论过程,处于研究阶段。两步随机接入过程可以提高时延,同时也能降低信令开销,目前有个基本的方式是,msgA传输四步随机接入过程的msg1和msg3,msgB传输四步随机接入过程的msg2和msg4,如图2-6所示。
其中,msgB可以包含成功随机接入响应(successRAR)、回退随机接入响应(fallbackRAR)和回退指示(Backoff Indication,BI)。进一步,msgB中不能复用多个终端设备的RRC消息;successRAR不能拆开到多个消息中,也就是说successRAR必须作为一个整体包含在一个msgB中。此外,SuccessRAR和fallbackRAR可以复用在一个msgB中。
以下对msgB中包含的各种类型的信息进行说明。
·对于successRAR,需要包含12比特的TAC、16比特的C-RNTI以及48比特的UE竞争解决标识。进一步,UE竞争解决标识的信息域应该位于successRAR MAC subPDU的负荷(payload)中,这里,successRAR MAC subPDU是指包含successRAR的MAC subPDU。再者,UE竞争解决标识的信息域在MAC subPDU的负荷之前。
·更进一步,msgB中包含的RRC消息需要满足以下需求:
1)msgB中是否有RRC消息需要清晰的指示;且RRC消息需要在successRAR之后;
2)对于重建原因(reestablishment case)触发的RRC消息,msgB中可以包含一个终端设备的多个RRC消息,但是如何指示msgB中携带了一个终端设备的多个RRC消息需要解决。
基于以上需求,提出了本申请实施例的以下技术方案,本申请实施例的技术方案旨在解决如何指示msgB中是否存在RRC消息,以及如何指示msgB中存在多个RRC消息的问题。
图3为本申请实施例提供的信息指示方法的流程示意图,如图3所示,所述信息指示方法包括以下步骤:
步骤301:终端设备接收第一消息,所述第一消息包括MAC PDU,所述MAC PDU携带第一指示信息和/或第二指示信息;其中,所述第一指示信息用于确定所述MAC PDU中是否包含第一类MAC subPDU,所述第二指示信息用于确定所述MAC PDU中包含的第一类MAC subPDU的数目;所述第一类MAC subPDU为包含RRC消息的MAC subPDU。
本申请实施例中,网络设备发送第一消息,终端设备接收第一消息。可选地,所述网络设备可以是基站,如gNB。
本申请实施例中,所述第一消息为两步随机接入过程中的msgB。其中,所述第一消息包括MAC PDU,可选地,可以将该MAC PDU称为msgB MAC PDU。
在一可选实施方式中,所述MAC PDU包括以下至少之一:
第二类MAC subPDU,所述第二类MAC subPDU只包括第二子头,所述第二子头包含BI信息;
第三类MAC subPDU,所述第三类MAC subPDU包括第三子头和成功successRAR;
第一类MAC subPDU,所述第一类MAC subPDU包括第一子头和SDU,所述SDU包含RRC消息;
第四类MAC subPDU,所述第四类MAC subPDU包括第四子头和fallbackRAR;
第五类MAC subPDU,所述第五类MAC subPDU包含第五子头和填充(padding),或者只包含第五子头(比如当padding的比特数为0时)。
上述方案中,所述第二类MAC subPDU是指包含BI信息的MAC subPDU,可选地,可以将所述第二类MAC subPDU称为BI MAC subPDU。
上述方案中,所述第三类MAC subPDU是指包含successRAR的MAC subPDU,可选地,可以将所述第三类MAC subPDU称为successRAR MAC subPDU。
上述方案中,所述第一类MAC subPDU是指包含RRC消息的MAC subPDU,可选地,可以将所述第一类MAC subPDU称为RRC MAC subPDU。
上述方案中,所述第四类MAC subPDU是指包含fallbackRAR的MAC subPDU,可选地,可以将所述第四类MAC subPDU称为fallbackRAR MAC subPDU。
上述方案中,所述第五类MAC subPDU是指包含padding的MAC subPDU,可选地,可以将所述第五类MAC subPDU称为padding MAC subPDU。当padding为0时,这个MAC subPDU可以不用包含padding,也就是说只有MAC subheader。
在一可选实施方式中,对于所述MAC PDU包含多个第一类MAC subPDU的情况,所述多个第一类MAC subPDU包含同一终端设备的不同RRC消息。
举个例子:一个RRC MAC subPDU包含一个RRC消息,多个RRC MAC subPDU共包含多个RRC消息,所述多个RRC消息为同一终端设备的消息。这种场景主要用于当2-step CBRA在RRC重建场景时(RRC re-establishment),网络可能会在msgB中响应同一个终端设备的RRC重建立消息(RRC re-establishment message)或者是RRC重配置消息(RRC reconfiguration message)。
在一可选实施方式中,在所述MAC PDU中,所述第一类MAC subPDU位于所述第三类MAC subPDU之后,该第一类MAC subPDU和该第三类MAC subPDU都是响应同一个终端设备。。
举个例子:在msgB MAC PDU中,如果包含RRC MAC subPDU,那么RRC MAC subPDU需要位于同一个终端设备的successRAR MAC subPDU之后。
以下结合图4-1对msgB MAC PDU的结构进行举例说明,需要说明的是,图4-1所示的msgB MAC PDU的结构仅为一种可选的示例。
如图4-1所示,一个msgB MAC PDU中可以包含一个或者多个MAC subPDU,MAC subPDU可以是如下几种:
1)BI MAC subPDU:BI MAC subPDU包含一个MAC子头(MAC subheader),这个MAC  subheader至少包含BI信息,一种参照示例如图4-1中的子头1。进一步,可选地,子头1的格式如图4-2所示。
2)successRAR MAC subPDU:successRAR MAC subPDU包含一个MAC subheader(参照图4-1中的子头2)和一个successRAR。进一步,这个MAC subheader中不包含48比特的UE竞争解决标识。进一步,可选地,子头2的格式如图4-3所示。
3)RRC MAC subPDU:RRC MAC subPDU包含一个MAC subheader(参照图4-1中的子头3)和一个包含RRC消息的服务数据单元(Service Data Unit,SDU)。进一步,可选地,子头3根据其中L域的长度可以有两种类型,子头3的格式如图4-4所示。
4)fallbackRAR MAC subPDU:fallbackRAR MAC subPDU包含一个MAC subheader(参照图4-1中的子头4)和一个fallbackRAR。进一步,可选地,子头4的格式如图4-5所示。
其中,msgB MAC PDU中可以包含一个或者多个同一个UE的RRC MAC subPDU,这些RRC MAC subPDU中的RRC消息属于一个终端设备。此外,RRC MAC subPDU需要在successRAR MAC subPDU之后,successRAR MAC subPDU和这些RRC MAC subPDU属于一个终端设备。
需要指出的是,图4-1所示的子头1对应于本申请实施例中的第二子头,子头2对应于本申请实施例中的第三子头,子头3对应于本申请实施例中的第四子头,子头4对应于本申请实施例中的第四子头。
终端设备在解码MAC PDU的时候,并不知道该MAC PDU中是否包含了RRC消息,也不知道包含了几个RRC消息。为此,本申请实施例的技术方案,通过在所述MAC PDU携带第一指示信息和/或第二指示信息来明确MAC PDU中的RRC消息的位置和/或数量。以下对所述第一指示信息和/或所述第二指示信息的实现进行详细说明。

所述第三子头携带所述第一指示信息,所述第一指示信息用于指示所述第三子头所在的第三类MAC subPDU之后是否跟随所述第一类MAC subPDU;且,所述第一子头携带所述第一指示信息,所述第一指示信息用于指示所述第一子头所在的第一类MAC subPDU之后是否跟随所述第一类MAC subPDU。
举个例子:参照图4-1,增强子头2的格式,该子头2至少包含第一指示信息,该第一指示信息用于指示该子头2所在的successRAR MAC subPDU之后是否跟随RRC MAC subPDU(或者说是否跟随RRC消息)。此外,增强子头3的格式,该子头3至少包含第一指示信息,该第一指示信息用于指示该子头3所在的RRC MAC subPDU之后是否跟随RRC MAC subPDU(或者说是否跟随RRC消息)。
具体实现时,所述第一子头可以重用R-15的MAC subheader格式,因此可以对其进行增强。
以下结合具体示例说明增强的子头2和子头3的格式。

E:增强的指示域,表示该MAC subPDU之后是否跟随RRC message MAC subPDU。
这里,E即代表所述第一指示信息,需要说明的是,“E”的名称仅为示例性描述。
在一个例子中,E=0(或者1)表示该MAC subPDU之后跟随RRC message MAC subPDU,E=1(或者0)表示该MAC subPDU之后不跟随RRC message MAC subPDU。
以下通过其他描述方式对所述第三子头中增强的指示域进行说明:

L:长度信息,可以为8比特(如(a)图所示)或者16比特(如(b)图所示);
E:增强的指示域,表示该MAC subPDU之后是否跟随RRC message MAC subPDU。
这里,E即代表所述第一指示信息,需要说明的是,“E”的名称仅为示例性描述。

举个例子:参照图4-1,增强子头1的格式,该子头1至少包含第二指示信息,该第二指示信息用于指示msgB MAC PDU中包含的RRC MAC subPDU的数量。终端设备基于子头1,能够知道msgB MAC PDU中包含了几个RRC消息,但是还不知道是哪个MAC subPDU后面包含了这些RRC消息,为此,增强子头2的格式,该子头2至少包含第一指示信息,该第一指示信息用于指示该子头2所在的successRAR MAC subPDU之后是否跟随RRC MAC subPDU(或者说是否跟随RRC消息)。
以下结合具体示例说明增强的子头1和子头2的格式。

举个例子:参照图4-1,增强子头2的格式,该子头2至少包含第二指示信息,该第二指示信息用于指示msgB MAC PDU中包含的RRC MAC subPDU的个数。需要说明的是,通过在子头2中携带第二指示信息,隐式的指示了该子头2所在的successRAR MAC subPDU之后是否跟随RRC MAC subPDU(或者说是否跟随RRC消息),与此同时,也指示了RRC MAC subPDU的个数。
增强的子头2(即successRAR MAC subPDU的子头,即所述第三子头)的格式如图5-5所示,其中,
T:表示类型,指示不同类型的MAC subPDU;
N:表示该msgB MAC PDU中包含的RRC MAC subPDU的个数。
需要说明的是,本申请实施例中的上述新增的指示域(如E、N)所占用的比特数仅为示例性的。比如图5-3、图5-4、图5-5中的N占用2比特,N所占用的比特数不局限于2比特,还可以是其他比特数,可选地,可以根据msgB MAC PDU中包含的RRC MAC subPDU的个数来确定N占用的比特数。

举个例子:参照图4-1,增强子头3(即所述第一子头)的格式,该子头3至少包含第一指示信息,该第一指示信息用于指示子头3所在的MAC subPDU是否为包含RRC消息的MAC subPDU。
具体实现时,所述第一子头可以重用R-15的MAC subheader格式,因此可以对其进行增强。
以下结合具体示例说明增强的子头3的格式。
增强的子头3(即RRC MAC subPDU的子头,即所述第一子头)的格式如图5-6所示,其中,
F:指示该子头携带的长度信息是8比特还是16比特;
L:长度信息,可以为8比特(如(a)图所示)或者16比特(如(b)图所示);
