本公开涉及通信技术领域,特别是指一种随机接入信息的获取、发送方法及网络节点。
在传统的随机接入流程中,用户设备在空闲态完成随机接入需要4步(除complete消息),称为四步随机接入(4-step RACH)。现在提出一种技术方案,用户设备在空闲态完成随机接入需要2步,称为两步随机接入(2-Step RACH)。
但对于2-step RACH,随机接入响应的设计方案尚未明确。
发明内容
本公开要解决的技术问题是提供一种随机接入信息的获取、发送方法及网络节点,能够明确两步随机接入过程中随机接入响应的内容。

图8为本公开实施例网络侧设备的结构示意图;
图9为本公开实施例网络侧设备的组成示意图;
图10为本公开实施例用户设备的组成示意图。
为使本公开的实施例要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
在本公开实施例中,用户设备可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant,PDA)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备。需要说明的是,在本公开实施例中并不限定用户设备的具体类型。
网络侧设备可以是是基站、中继或接入点等。基站可以是5G及以后版本的基站(例如:5G NR NB),或者其他通信系统中的基站(例如:演进型基站(Evolutional Node B,eNB))。需要说明的是,在本公开实施例中并不限定网络侧设备的具体类型。
四步随机接入的流程如图1所示,包括如下步骤:
步骤1、网络侧设备给UE配置四步随机接入的配置信息(4-Step RACH configuration)。
步骤2、UE向网络侧设备发送Msg1。
在本步骤中,Msg1可以包括随机接入前导码(Preamble),但不仅限于此。
步骤3、网络侧设备向UE发送Msg2。
在本步骤中,Msg2可以表现为随机接入响应(Random Access Response,RAR)消息。Msg2中可以包括回退指示(Backoff Indicator,BI)、上行授权(Uplink Grant)信息、随机接入-无线网络临时标识(Random Access-Radio Network Temporary Identifier,RA-RNTI)。
但应理解的是,在实际应用中,Msg2可以包括BI、上行授权信息和RA-RNTI中的一项或多项组合,当然,Msg2还可以包括其他信息,如时间提前命令(Timing Advance Command,TAC)等。
步骤4、UE向网络侧设备发送Msg3。
在本步骤中,Msg3可以表现为无线资源控制(Radio Resource Control,RRC)连接请求消息。Msg2中可以包括系统架构演进临时移动站标识符(SAE Temporary Mobile Station Identifier,S-TMSI),但不仅限于此。
步骤5、网络侧设备向UE发送Msg4。
在本步骤中,Msg4可以表现为RRC连接建立消息。Msg3中可以包括竞争解决(Contention Resolution),但不仅限于此。
步骤6、UE向网络侧设备发送Msg5。
在本步骤中,Msg5可以表现为RRC连接完成消息。
对于四步随机接入,值得指出的是,常规意义下Msg1-Msg5在具体的连接态和空闲态的连接建立过程中可能表现不同的消息形态,该四步随机接入过程的Msg1-Msg5的消息可以是无线资源控制(RRC)消息、媒体接入控制(Media Access Control,MAC)控制元素(CE)或者物理层指示、数据、序列等。
两步随机接入的流程如图2所示,包括以下步骤:
步骤(step)0:网络侧(gNB)给用户设备(User Equipment,UE)配置两步随机接入的配置信息(2-Step RACH configuration),如包括:Msg1和Msg2对应的发送资源信息;
步骤1:UE触发2-step RACH过程。将请求信息(Msg1)发送给网络侧,如通过物理上行共享信道(Physical Uplink Shared Channel,PUSCH)发送数据(data)和UE标识(UE-ID);
步骤2:网络侧发送确认信息(Msg2)给UE。如果UE接收Msg2失败,则UE重新发送Msg1。
对于两步随机接入,值得指出的是,Msg1-Msg2在具体的连接态和空闲态的连接建立过程中可能表现不同的消息形态,区分于传统的四步随机接入Msg1-Msg5,该两步随机接入Msg1-Msg2的消息可以是RRC消息、MAC CE或者物理层指示、数据、序列等。
对于2-step RACH而言,step1相当于将正常RACH过程中的Msg1和Msg3合并发送,step2相当于将正常RACH过程中的Msg2和Msg4合并。
图3为由媒体接入控制随机接入响应(Random Access Response,RAR)构成的MAC协议数据单元(Protocol Data Unit,PDU)示例,图4为MAC RAR的结构示意图。
简单来说,RAR分为三种MAC子(sub)PDU。一种只有BI的,一种只有随机前导码标识(Random Access Preamble Identifier,RAPID)的,一种有RAPID+RAR的。RAR的有效载荷(payload)内容有定时提前命令(Timing Advance Command),上行授权(UL Grant)和临时-小区无线网络临时标识(Temporary Cell Radio Network Temporary Identifier,Temporary C-RNTI)。其中,只有BI的sub PDU作用是对于没有检测到RAPID的UE,执行该BI;只有RAPID的sub PDU作用是对于检测到该RAPID的UE,作为SI request(系统信息请求)的ACK;有RAPID+RAR的sub PDU作用是对于检测到该RAPID的UE,执行对应的RAR内容。
对于4-step RACH过程,即处于空闲态(IDLE)/非激活态(inative)状态,从IDLE/inactive状态转换为连接(connnect)状态过程中使用4-step的UE,在接收RAR的时候,UE检测到自己的RAPID后,获得对应的上行授权,在上行授权上发送Msg3,通过Msg4完成竞争解决,同时Msg4提供重配消息,并且将T-C-RNTI升级为小区无线网络临时标识(Cell Radio Network Temporary Identifier,C-RNTI)),之后网络侧可以使用该C-RNTI进行调度。
但对于2-step RACH,如何在随机接入响应中完成4-step RACH中Msg2+Msg4的功能,以及随机接入响应使用的随机接入无线网络临时标识符如何计算,都尚未明确。
为了解决上述问题,本公开的实施例提供一种随机接入信息的获取方法及网络节点,能够明确两步随机接入过程中随机接入响应的内容。
本公开实施例提供了一种随机接入信息的获取方法,应用于用户设备,如图5所示,所述方法包括:
步骤101:接收网络侧设备发送的随机接入响应,所述随机接入响应包括预留比特、上行授权、回退指示、时间提前量、前导序列或其他序列标识ID、终端ID、竞争解决ID、无线资源控制RRC消息、RRC消息和各ID之间的关联关系、连接态无线网络临时标识符中至少一种,所述各ID包括前导序列或其他序列ID、终端ID和竞争解决ID至少之一。
本实施例可以明确两步随机接入过程中随机接入响应的内容。
进一步地,所述方法还包括:
根据随机接入过程的传输资源信息计算随机接入无线网络临时标识符,比如RA-RNTI;
所述接收网络侧设备发送的随机接入响应包括:
通过所述随机接入无线网络临时标识符接收所述随机接入响应。
进一步地,所述方法还包括:
向网络侧设备发送随机接入请求;
所述传输资源信息包括:随机接入请求中携带的随机接入前导码或者其他码序列对应的时域资源和/或频域资源和/或空域资源和/或功率域资源;和/或
随机接入请求中携带的发送物理上行共享信道对应的时域资源和/或频域资源和/或空域资源和/或功率域资源。
进一步地,计算所述随机接入无线网络临时标识符包括:
根据随机接入请求中携带的随机接入前导码或者其他码序列对应的时域资源和/或频域资源和/或空域资源和/或功率域资源计算所述随机接入无线网络临时标识符;和/或
根据随机接入请求中携带的发送物理上行共享信道对应的时域资源和/或频域资源和/或空域资源和/或功率域资源计算所述随机接入无线网络临时标识符。
对于处于IDLE/inative状态,从IDLE/inactive转换为connnect状态过程中使用2-step RACH的UE,在接收RAR的时候,UE需要完成竞争解决(contention resolution)、重配消息、C-RNTI确定等功能。
类似于长期演进(Long Term Evolution,LTE)机制,RAR的格式包含多个UE的信息,可以被多个UE检测到随机接入无线网络临时标识符(Random Access-Radio Network Tempory Identity,RA-RNTI),每个UE再根据对应的RAPID检测到自己发送的随机接入前导码(preamble)的ID。
发起RACH Msg1可能使用preamble或者物理上行共享信道(Physical Uplink Shared Channel,PUSCH)或者两者组合;关于RA-RNTI计算,可能用到的计算参数包括以下:
发起RACH Msg1所使用的preamble,以及对应的时域资源和/或频域资源和/或空域资源和/或功率域资源;和/或
发起RACH Msg1所使用的PUSCH,以及对应的时域资源和/或频域资源和/或空域资源和/或功率域资源。
进一步地,在两步随机接入过程的随机接入响应所在的控制资源集频域位置和四步随机接入过程的随机接入响应所在的控制资源集频域位置不同时,利用以下至少一种参数计算所述随机接入无线网络临时标识符:
两步随机接入过程对应的物理随机接入信道PRACH第一个正交频分复用符号OFDM的位置序号,两步随机接入过程对应的PRACH信道所在系统帧的第一个时隙的序号,两步随机接入过程对应的PRACH所在频域位置的序号,发送随机接入请求的上行载波的指示。
具体地,如果2步RACH接收RAR所在的控制资源集(coreset)频域位置和常规RACH(即4步RACH)不一样,则可以采用以下公式计算RA-RNTI:
RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id(2-step RACH carrier)
其中,s_id为两步随机接入过程对应的物理随机接入信道PRACH第一 个正交频分复用符号OFDM的位置序号,0≤s_id<14,t_id是两步随机接入过程对应的PRACH信道所在系统帧的第一个时隙的序号,0≤t_id<80,f_id是两步随机接入过程对应的PRACH所在频域位置的序号,and ul_carrier_id是发送随机接入请求的上行载波的指示,对于2步RACH,and ul_carrier_id的值可以取1,对于4步RACH,and ul_carrier_id的值可以取0;或者,对于4步RACH,and ul_carrier_id的值可以取0,对于上行辅助载波,and ul_carrier_id的值可以取1,对于2步RACH,and ul_carrier_id的值可以取2,等等,取值不做具体限制。
可选地,还可以利用PUSCH相关的计算参数计算RA-RNTI。
进一步地,在两步随机接入过程的随机接入响应所在的控制资源集频域位置和四步随机接入过程的随机接入响应所在的控制资源集频域位置相同时,两步随机接入过程的随机接入无线网络临时标识符与四步随机接入过程的随机接入无线网络临时标识符使用同一段RNTI资源。
进一步地,四步随机接入过程的随机接入无线网络临时标识符使用该段RNTI资源的前半部分,两步随机接入过程的随机接入无线网络临时标识符使用该段RNTI资源的后半部分。
即如果2步RACH接收RAR所在的coreset频谱位置和常规RACH一样,即共享一段资源接收RAR,则预留一段未被其他RNTI占用的RNTI资源,前半部分的RNTI资源供现有的RA-RNTI使用,后一部分的RNTI资源适用于2-step RACH的RA-RNTI。即2步RACH使用的RNTI区间可以如下:[legacy(maxRA-RNTI)+1,2-step RACH RA-RNTI],其中,legacy(maxRA-RNTI)为现有的RA-RNTI的最大值。
进一步地,RAR中包含的消息和UE的关联关系如下:
如果RAR是单播消息,则该RAR对应的UE ID和RAR中含有的无线资源控制连接建立消息(RRC connection setup)和/或无线资源控制连接恢复消息(RRC resume)和/或无线资源控制重配消息是对应的。
如果RAR是广播消息,对应不同的UE,则该RAR中的RRC connection setup/RRC resume/或无线资源控制重配消息等,需要和一个UE ID(可以是竞争解决ID或者可以唯一标识UE的ID)建立关联关系,其中一条消息可以对 应多个UE ID。所述随机接入响应中的以下消息对应至少一个用户终端标识:
无线资源控制连接建立消息;
无线资源控制连接恢复消息;
无线资源控制重配消息;
其他RRC消息、MAC控制元素、C-RNTI或者物理层控制指示等。
进一步地,所述随机接入响应中包括有每个竞争解决的用户设备的小区无线网络临时标识和无线资源控制消息。对于RAR中的C-RNTI使用,与相关技术中的RAR不同,本实施例的RAR中直接含有每个竞争解决UE的C-RNTI和RRC消息,C-RNTI包含在RRC消息或者MAC CE中,而不是将之前的T-C-RNTI自动升级成C-RNTI。
进一步地,所述小区无线网络临时标识包括在无线资源控制消息或媒体接入控制控制元素消息中。
进一步地,所述方法还包括:
根据所述小区无线网络临时标识识别自身为竞争解决的用户设备后,执行所述无线资源控制消息的内容。即对于收到的RRC消息,UE在确定自身是竞争解决的UE之后再执行RRC消息内容。
进一步地,所述方法还包括:
根据所述小区无线网络临时标识进行后续无线资源控制消息的调度。
RAR中对每一个竞争解决的UE都分配对应的C-RNTI,后续的RRC消息通过该分配的C-RNTI进行调度,传输RRC消息。
本实施例的技术方案适用于新空口(New Radio,NR)以及后续演进网络。
本公开实施例还提供了一种随机接入信息的发送方法,应用于网络侧设备,如图6所示,所述方法包括:
步骤201:向用户设备发送随机接入响应,所述随机接入响应包括预留比特、上行授权、回退指示、时间提前量、前导序列或其他序列标识ID、终端ID、竞争解决ID、无线资源控制RRC消息、RRC消息和各ID之间的关联关系、连接态无线网络临时标识符中至少一种,所述各ID包括前导序列或其他序列ID、终端ID和竞争解决ID至少之一。
