本申请主张在2016年8月5日在中国提交的中国专利申请No.201610635210.7的优先权,其全部内容通过引用包含于此。
技术领域
本公开文本涉及通信技术领域,尤其涉及一种无线网络中的接入方法及设备。
背景技术
在LTE(Long Term Evolution,长期演进)***中随机接入的原因主要有如下几种:
(1)从RRC_IDLE状态接入(也称为初始接入,initial access);
(2)无线链路失败发起RRC(Radio Resource Control,无线资源控制)连接重建(也是初始接入的一种);
(3)切换过程需要随机接入;
(4)UE(User Equipment,用户设备)处于RRC_CONNECTED时有下行数据到达;
(5)UE处于RRC_CONNECTED时有上行数据到达;
对于有下行数据到达和切换两种情况,如果有专用preamble(前同步码),则可以使用非竞争随机接入,非竞争随机接入的过程如图1所示,主要分为三步:
Msg0:基站向UE分配用于非竞争随机接入的专用ra-PreambleIndex(Random Access Preamble,随机接入前导码)以及随机接入使用的PRACH(Physical Random Access Channel,物理随机接入信道)资源ra-PRACH-MaskIndex(PRACH Mask Index,PRACH Mask编号):对于下行数据到达引起的非竞争随机接入使用PDCCH(Physical Downlink Control channel,物理下行控制信道)携带这些信息,对于切换引起的非竞争随机接 入通过handover command(切换命令)携带这些信息。
Msg1:UE根据Msg0指示的ra-PreambleIndex和ra-PRACH-MaskIndex,在指定的PRACH资源上向基站发送指定的专用preamble。基站接收到Msg1后根据Msg1计算上行TA(Timing Advance,定时提前量)。
Msg2:基站向UE发送随机接入响应,随机接入响应中包含定时提前量信息,通知UE后续上行传输的定时提前量。
对于其他所有随机接入原因引起的随机接入均可以使用竞争随机接入,竞争随机接入的过程如图2所示,主要分为四步:
Msg1:UE选择随机接入preamble和PRACH资源并利用该PRACH资源向基站发送所选的随机接入preamble;
Msg2:基站接收到preamble,计算定时提前量TA,并向UE发送随机接入响应,随机接入响应中至少包含该Temporary(临时)C-RNTI(Cell-Radio Network Temporary Identifier,小区无线网络临时标识)定时提前量信息和针对Msg3消息的UL grant(UpLink grant,上行调度授权);
Msg3:UE在Msg2指定的UL grant上发送上行传输,不同随机接入原因触发的随机接入过程对应的Msg3消息传输的内容可能不同,比如对于初始接入,Msg3传输的是RRC连接建立请求;
Msg4:竞争解决消息,UE根据Msg4可以判断随机接入是否成功;
相关技术中的LTE***随机接入过程设计是针对单层接入网节点的,即随机接入的整个信令交互都是发生在基站和UE之间。
随着5G(5th Generation,第五代)***接入网节点分层,需要考虑在这种接入网结构下如何执行接入过程。如果分布式处理节点仅有物理层功能,其他功能都位于集中处理节点,那么最简单的方式是复用相关技术中的LTE的随机接入流程,即接入过程所有信令交互都发生在UE和集中处理节点之间。但是如果分布式处理节点具备部分L2功能,那么需要考虑接入过程如何进行信令交互,以缩短接入时延,优化***性能。
现在尚处于5G初级研究阶段,目前公开的资料中并没有提出分层接入网架构下的接入过程的具体方案。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例,然而应当理解,可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反,提供这些实施例是为了能够更透彻地理解本公开,并且能够将本公开的范围完整的传达给本领域的技术人员。
本领域技术人员知道,本公开文本的实施方式可以实现为一种***、装置、设备、方法或计算机程序产品。因此,本公开文本的实施例可以具体实现为以下形式:完全的硬件、完全的软件(包括固件、驻留软件、微代码等),或者硬件和软件结合的形式。
超密集组网是未来移动通信***发展的一个趋势,在超密集组网情况下,为了实现对大量分布式处理节点的统一控制面管理,需要将部分协议功能进行集中处理节点。这样就形成了集中处理节点和分布式处理节点的双层接入网架构。其中分布式处理节点也称为TRP,集中处理节点也称为CU(Central Unit,集中处理节点)或者NR eNB(New RAT(Radio Access Technology)eNB(evolvedNode B),新接入技术基站)。对于集中处理节点,根据功能不同,还可以进一步划分为集中处理节点的控制面和集中处理节点的用户面。
基于上述描述,未来移动通信***的网络架构示意图如图3所示。在本公开文本实施例中,分布式处理节点可以是但不限于TRP或其他类似的分布式处理节点。集中处理节点可以是但不限于NR eNB或者CU或者其他类似的集中处理节点。
在本公开文本一些实施例中,参见图4,图中示出了一种无线网络中的接入方法,该接入方法适用于分层网络架构中的分布式处理节点,该分层网络架构中还包括集中处理节点,该接入方法的具体步骤如下:
步骤401、分布式处理节点接收UE发送的Msg1消息,所述Msg1消息包含接入专用码或序列;
步骤402、分布式处理节点向所述UE发送用于响应Msg1消息的Msg2消息,其中,所述Msg2消息中包含临时RNTI,所述临时RNTI是分布式处理节点可用的RNTI集合中一个当前未使用的RNTI。
在本实施例中,可选地,在分布式处理节点向UE发送用于响应Msg1消息的Msg2消息之后,接入方法还包括:
分布式处理节点接收UE发送的Msg3消息,Msg3消息包含有与随机接入原因对应的内容;
分布式处理节点解析Msg3消息,并根据解析结果进行相应的处理。
需要说明的是,Msg3消息包含的内容根据随机接入目的不同而不同,例如在竞争随机接入场景中,Msg3消息包含的内容可以是UE当前数据传输使用的RNTI对应的MAC CE,或者Msg3消息包含的内容是UE RRC连接建立/重建请求标识请求信息(比如Msg3消息中携带的CCCH(Common Control Channel,公共控制信道)SDU(Service Data Unit,服务数据单元)),当然也并不限于此。
此外,在LTE***中,随机接入触发条件有多种:比如初始接入、切换、RRC连接重建、上/下行数据到达但上行失步、定位等。基于不同触发条件触发的随机接入,其Msg3中携带的内容可能不同,比如对于初始接入/RRC连接重建,Msg3中携带的是CCCH SDU;对于切换,则携带的是C-RNTI MAC CE;对于其他原因触发的随机接入,切换消息中至少携带C-RNTI MAC CE。
在本实施例中,可选地,所述分布式处理节点解析所述Msg3消息,并根据解析结果进行相应的处理,包括:
分布式处理节点解析Msg3消息,Msg3消息包含UE当前数据传输使用的RNTI对应的RNTI MAC CE;
分布式处理节点向UE发送Msg4消息,所述Msg4消息使用所述RNTI寻址。
在本实施例中,可选地,分布式处理节点解析所述Msg3消息,并根据解析结果进行相应的处理,包括:
分布式处理节点解析Msg3消息,所述Msg3消息包含RRC连接建立/重建请求标识信息;
分布式处理节点向所述UE发送Msg4a消息,Msg4a消息包含RRC连接建立/重建请求标识信息;

在本实施例中,可选地,分布式处理节点可用的RNTI集合的确定方式为:
方式一、由集中处理节点确定集中处理节点可用的RNTI集合,再由所述集中处理节点将所述集中处理节点可用的RNTI集合的子集分配给所述集中处理节点管理的分布式处理节点,作为所述分布式处理节点可用的RNTI集合,一个集中处理节点下不同分布式处理节点可用的RNTI集合不存在交叠;
方式二、由集中处理节点确定集中处理节点可用的RNTI集合,再由所述集中处理节点将所述集中处理节点可用的RNTI集合的子集或全集分配给所述集中处理节点管理的分布式处理节点,作为所述分布式处理节点可用的RNTI集合,不同分布式处理节点可用的RNTI集合允许交叠。
在本实施例中,可选地,基于上述方式二,所述接入方法还包括:
如果所述Msg3消息包含RRC连接建立/RRC连接重建请求标识信息,所述分布式处理节点通过分布式处理节点和集中处理节点之间的接口将所述RRC连接建立/RRC连接重建请求标识信息和所述临时RNTI通知给所述集中处理节点,由所述集中处理节点根据所述临时RNTI以及所述分布式处理节点的TRP ID组合作为所述UE在所述集中处理节点中的标识。
在本实施例中,Msg1消息、Msg2消息、Msg3消息和Msg4消息均发生 在UE和分布式处理节点之间。
对于RRC连接建立/重建,分布式处理节点需要解析Msg3并提取出其中的RRC连接建立/重建请求标识信息(比如Msg3中携带的CCCH SDU),并通过分布式处理节点和集中处理节点之间的接口将该RRC连接建立/重建请求标识信息交互给集中处理节点,集中处理节点进行RRC连接建立/重建判决,并向分布式处理节点回复响应消息,然后由分布式处理节点将该响应消息转发给UE。
通过上述实施例,可以实现分层接入网架构下的接入过程,并且能够保证该接入过程具有较小的接入时延,并且可以支持竞争失败的UE能够快速发现竞争失败,从而再次发起随机接入。
在本公开文本一些实施例中,参见图5,图中示出了一种无线网络中的接入方法,该接入方法适用于分层网络架构中的UE,该分层网络架构中还包括集中处理节点和分布式处理节点,该接入方法的具体步骤如下:
步骤501、UE接收分布式处理节点发送的Msg2消息,其中,所述Msg2消息中包含临时RNTI,所述临时RNTI是分布式处理节点可用的RNTI集合中一个当前未使用的RNTI。
可选地,在上述步骤501之前,UE向分布式处理节点发送Msg1消息,Msg1消息包含接入专用码或序列。
在本实施例中,可选地,所述接入方法还包括:

所述UE接收所述分布式处理节点发送所述Msg4消息,所述Msg4消息使用所述RNTI寻址。在本实施例中,可选地,所述接入方法还包括:
所述UE向所述分布式处理节点发送Msg3消息,所述Msg3消息包含RRC连接建立/重建请求标识信息;
如果所述UE在预定时间内(例如竞争解决定时器超时前)接收到所述分布式处理节点发送的Msg4a消息,且所述Msg4a消息包含所述RRC连接建立/重建请求标识信息,则判断竞争成功;
所述UE接收分布式处理节点发送的用于响应Msg3消息的Msg5消息;
如果所述UE在预定时间内(例如竞争解决定时器超时前)没有收到所述分布式处理节点发送的Msg4a消息,所述UE可以按照回退机制,尽快重新发起随机接入。
在本实施例中,可选地,所述分布式处理节点可用的RNTI集合的确定方式为:
由集中处理节点确定集中处理节点可用的RNTI集合,再由所述集中处理节点将所述集中处理节点可用的RNTI集合的子集分配给所述集中处理节点管理的分布式处理节点,作为所述分布式处理节点可用的RNTI集合,一个集中处理节点下不同分布式处理节点可用的RNTI集合不存在交叠。
在本实施例中,可选地,基于上述确定方式,所述接入方法还包括:
如果所述Msg3消息包含RRC连接建立/RRC连接重建请求标识信息,且所述UE通过所述Msg4a消息判断竞争成功,所述UE将所述临时RNTI作为其后续数据传输使用的RNTI;或者
如果所述Msg3消息包含RRC连接建立/RRC连接重建请求标识信息,所述UE在收到RRC连接建立/RRC连接重建消息之前,一直使用临时RNTI;
当所述UE接收到所述集中处理节点通过分布式处理节点发送的RRC连接建立/RRC连接重建消息后,所述UE释放所述临时RNTI,并使用所述RRC连接建立/RRC连接重建消息中网络侧分配给UE的RNTI作为所述UE后续数据传输使用的RNTI。
在本实施例中,可选地,所述分布式处理节点可用的RNTI集合的确定方式为:
由集中处理节点确定集中处理节点可用的RNTI集合,再由集中处理节点将所述集中处理节点可用的RNTI集合的子集或全集分配给所述集中处理节点管理的分布式处理节点,作为所述分布式处理节点可用的RNTI集合,不同分布式处理节点可用的RNTI集合允许交叠。
在本实施例中,可选地,基于上述确定方式,如果所述Msg3消息包含RRC连接建立/RRC连接重建请求标识信息,所述接入方法还包括:
所述UE接收到集中处理节点通过分布式处理节点发送的RRC连接建立/RRC连接重建消息;
若所述RRC连接建立/RRC连接重建消息包含新分配的RNTI,则所述UE释放所述临时RNTI,并使用新分配的RNTI作为所述UE后续数据传输使用的RNTI;
若所述RRC连接建立/RRC连接重建消息不包含新分配的RNTI,则所述UE将所述临时RNTI作为新的RNTI,并使用新的RNTI作为所述UE后续数据传输使用的RNTI。
通过上述实施例,可以实现分层接入网架构下的接入过程,并且能够保证该接入过程具有较小的接入时延,并且可以支持竞争失败的UE能够快速发现竞争失败,从而再次发起随机接入。
在本公开文本一些实施例中,参见图6,图中示出了一种无线网络中的接入方法,具体步骤如下:
步骤601、分布式处理节点接收UE发送的Msg1消息,所述Msg1消息包含的内容由随机接入资源分配消息Msg0消息分配;
在本实施例中,Msg0消息生成节点依据Msg0包含的内容不同而不同。对于RRC层触发的非竞争随机接入,Msg0由集中处理节点生成;对于其他MAC层触发的非竞争随机接入,Msg0可以由分布式处理节点或集中式节点生成。
步骤602、分布式处理节点处理所述UE发送的所述Msg1消息,并生成与所述Msg1消息对应的Msg2消息,所述Msg2消息中包含临时RNTI,所述临时RNTI是分布式处理节点可用的RNTI集合中一个当前未使用的RNTI;
步骤603、分布式处理节点向所述UE发送所述Msg2消息。
可选地,所述分布式处理节点可用的RNTI集合的确定方式为:
由集中处理节点确定集中处理节点可用的RNTI集合,再由集中处理节点将所述集中处理节点可用的RNTI集合的子集分配给所述集中处理节点管理的分布式处理节点作为所述分布式处理节点可用的RNTI集合,一个集中处理节点下不同分布式处理节点可用的RNTI集合不存在交叠;或者
由集中处理节点确定集中处理节点可用的RNTI集合,再由集中处理节点将所述集中处理节点可用的RNTI集合的子集或全集分配给所述集中处理节点管理的分布式处理节点作为所述分布式处理节点可用的RNTI集合,不 同分布式处理节点可用的RNTI集合允许交叠。
通过上述实施例,可以实现分层接入网架构下的接入过程,并且能够保证该接入过程具有较小的接入时延。
在本公开文本一些实施例中,参见图7,图中示出了一种无线网络中的接入方法,具体步骤如下:
步骤701、UE向分布式处理节点发送Msg1消息,所述Msg1消息的内容由随机接入资源分配消息Msg0消息分配;
步骤702、所述UE接收所述分布式处理节点发送的所述Msg2消息,所述Msg2消息包含临时RNTI,所述临时RNTI是分布式处理节点可用的RNTI集合中一个当前未使用的RNTI。
可选地,所述接入方法还包括:
所述UE丢弃所述Msg2消息包含的临时RNTI,仍然使用根据所述Msg0消息获得的C-RNTI。
可选地,所述分布式处理节点可用的RNTI集合的确定方式为:
由集中处理节点确定集中处理节点可用的RNTI集合,再由集中处理节点将所述集中处理节点可用的RNTI集合的子集分配给所述集中处理节点管理的分布式处理节点作为所述分布式处理节点可用的RNTI集合,一个集中处理节点下不同分布式处理节点可用的RNTI集合不存在交叠;或者
由集中处理节点确定集中处理节点可用的RNTI集合,再由集中处理节点将所述集中处理节点可用的RNTI集合的子集或全集分配给所述集中处理节点管理的分布式处理节点作为所述分布式处理节点可用的RNTI集合,不同分布式处理节点可用的RNTI集合允许交叠。
通过上述实施例,可以实现分层接入网架构下的接入过程,并且能够保证该接入过程具有较小的接入时延。
在本公开文本一些实施例中,一个实施例适用的场景是:当UE当有数据传输可用的RNTI时的场景,比如:UE有下行数据到达,但是上行失步,且没有专用preamble或者sync序列;或者UE有上行数据到达,但是上行失步。
参见图8,图中示出了竞争随机接入过程,具体步骤如下:
步骤801、UE发送Msg1消息,Msg1消息终结于分布式处理节点。Msg1消息的内容可以是但不限于接入相关的码/序列,可以由分布式处理节点分配给UE。该码/序列可以是分布式处理节点自己管理的,也可以是由集中处理节点同一个分配并通知给分布式处理节点的。
不同分布式处理节点的码/序列允许有交叠。Msg1传输使用的资源使用的接入资源(比如PRACH资源)可以是由分布式处理节点分配,也可以是集中处理节点分配并通知给分布式处理节点。
步骤802、分布式处理节点处理UE发送的Msg1消息,并生成和Msg1消息对应的Msg2消息。Msg2消息可以使用物理层信令,也可以使用L2PDU(Protocol Data Unit,协议数据单元)传输中。其包含的内容和相关技术中LTE***Msg2消息包含的内容相同,具体包括UE对应的TA值、Msg3消息上行传输使用的资源、临时RNTI等信息。
Msg2消息中包含的临时RNTI的取值和集中处理节点使用的无冲突的UE标识管理方式有关。通过集中处理节点实现接入网无冲突的UE标识管理,具体可以有两种管理方式:
可选管理方式一(Alt1):集中处理节点确定集中处理节点可用的RNTI集合,并将其中的子集分配给其管理的分布式处理节点作为分布式处理节点可用的RNTI集合,一个集中处理节点下不同分布式处理节点的RNTI不存在交叠。
可选管理方式二(Alt2):集中处理节点确定集中处理节点可用的RNTI集合,并将该RNTI集合中的子集或者全集分配给其管理的分布式处理节点作为分布式处理节点可用,不同分布式处理节点的RNTI允许交叠,在集中处理节点可以通过TRP ID和RNTI唯一识别一个UE。
需要说明的是,无论集中处理节点实现接入网无冲突的UE标识管理使用上述哪种方法,分布式处理节点的行为是一致的,即从分布式节点可用的RNTI集合中选择一个当前未使用的RNTI作为UE的临时RNTI。
步骤803、UE向分布式处理节点发送Msg3消息。
Msg3消息包含的内容根据随机接入目的不同而不同,对于本实施例Msg3消息中包含的内容是UE当前数据传输使用的RNTI对应的RNTI MAC CE。
步骤804、分布式处理节点向UE发送Msg4消息。
分布式处理节点接收到Msg3消息并对其解析,可以通过C-RNTI加扰的PDCCH调度UE告知UE竞争成功,即Msg4消息。
在本公开文本一些实施例中,一个实施例适用的场景可以是:当UE没有数据传输可用的RNTI时的场景,例如:UE初始接入或者UE RRC连接重建。
参见图9,图中示出了一种竞争随机接入过程,具体步骤如下:
步骤901、UE向分布式处理节点发送Msg1消息,Msg1消息终结于分布式处理节点。Msg1消息的内容可以是但不限于接入相关的码/序列,可以由分布式处理节点分配给UE。该码/序列可以是分布式处理节点自己管理的,也可以是由集中处理节点同一个分配并通知给分布式处理节点的。
不同分布式处理节点的码/序列允许有交叠。Msg1消息传输使用的资源使用的接入资源(比如PRACH资源)可以是由分布式处理节点分配,也可以是集中处理节点分配并通知给分布式处理节点。
步骤902、分布式处理节点向UE发送Msg2消息;
分布式处理节点处理UE发送的Msg1消息,并生成和Msg1消息对应的Msg2消息。Msg2消息可以使用物理层信令,也可以使用L2PDU传输中。其包含的内容和相关技术中LTE***Msg2消息包含的内容相同,具体包括UE对应的TA值、Msg3消息上行传输使用的资源、临时RNTI等信息。
可选地,Msg2消息中包含的临时RNTI的取值和集中处理节点使用的无冲突的UE标识管理方式有关。通过集中处理节点实现接入网无冲突的UE标识管理,具体可以有两种管理方式:
可选管理方式一(Alt1):集中处理节点确定集中处理节点可用的RNTI集合,并将其中的子集分配给其管理的分布式处理节点作为分布式处理节点可用的RNTI集合,一个集中处理节点下不同分布式处理节点的RNTI不存在交叠。
可选管理方式二(Alt2):集中处理节点确定集中处理节点可用的RNTI集合,并将该RNTI集合中的子集或者全集分配给其管理的分布式处理节点作为分布式处理节点可用,不同分布式处理节点的RNTI允许交叠,在集中处理节点可以通过TRP ID和RNTI唯一识别一个UE。
需要说明的是,无论集中处理节点实现接入网无冲突的UE标识管理使用上述哪种方法,分布式处理节点的行为是一致的,即从分布式节点可用的RNTI集合中选择一个当前未使用的RNTI作为UE的临时RNTI。
步骤903、UE向分布式处理节点发送Msg3消息;
在本实施中,Msg3消息包含的内容根据随机接入目的不同而不同,对于本实施例Msg3消息中包含的内容是UE为RRC连接建立/重建请求标识信息(例如Msg3消息中携带的CCCH SDU)中包含的内容即RRC连接建立/重建请求。
步骤904、分布式处理节点向UE发送Msg4a消息;
分布式处理节点接收到Msg3消息并对其解析,如果可以成功解码(不需要解读出RRC连接建立/重建请求标识信息(比如Msg3消息中携带的CCCH SDU)的内容),则判断UE竞争成功,此时可以用临时RNTI加扰的PDCCH调度的下行数据传输将包含该RRC连接建立/重建请求标识信息(比如Msg3消息中携带的CCCH SDU)的MAC CE发送给UE。对于成功接收到该MAC CE的UE认为竞争成功,等待后续接收RRC连接建立/重建消息。对于同样发送了Msg3消息,但是在竞争解决定时器超时前没有成功接收到包含RRC连接建立/重建请求标识信息(比如Msg3消息中携带的CCCH SDU)的MAC CE,则可以按照回退机制,尽快重新发起随机接入。
步骤905、分布式处理节点向集中处理节点发送Msg3a消息;
分布式处理节点在向UE发送Msg4a消息的同时,需要将提取出的RRC连接建立/重建请求标识信息(比如Msg3中携带的CCCH SDU)发送给集中处理节点。
步骤906、集中处理节点向分布式处理节点发送Msg4b消息;
集中处理节点进行RRC连接建立/重建判决,一旦决定可以建立/重建RRC连接,则向分布式处理节点回复Msg4b消息,指示UE建立/重建RRC连接。
步骤907、分布式处理节点向UE发送Msg5消息;
基于上述可选管理方式一(Alt1),后续数据传输使用的RNTI有如下两种确定方法:
可选方式一(Option 1):如果Msg3消息包含RRC连接建立/重建请求标识 信息(比如MSG3中携带的CCCH SDU),那么UE一旦通过Msg4消息竞争成功,可以将该临时RNTI作为其后续数据传输使用的RNTI。
可选方式二(Option 2):如果Msg3消息包含RRC连接建立/重建请求标识信息(比如MSG3中携带的CCCH SDU),对于要接入网络的UE而言,在接收到RRC连接建立/重建消息之前一直使用临时RNTI。只有当UE接收到集中处理节点通过分布式处理节点发送的RRC连接建立/重建消息后,才释放该临时RNTI,并使用RRC连接建立请求/重建消息中网络侧分配给UE的携带的RNTI作为UE后续数据传输使用的RNTI。
基于上述可选管理方式二(Alt2),后续数据传输使用的RNTI按照如下方式确定:如果Msg3消息中包含RRC连接建立/重建请求标识信息(比如Msg3消息中携带的CCCH SDU),分布式处理节点通过分布式处理节点和集中处理节点之间的接口将该RRC连接建立/重建请求标识信息(比如Msg3消息中携带的CCCH SDU)通知给集中处理节点时,需要将该临时RNTI通知给集中处理节点,集中处理节点根据该临时RNTI以及该分布式处理节点的TRP ID组合作为该UE后在集中处理节点的标识。对于要接入网络的UE,如果网络侧的RRC连接建立/重建消息包含新分配的RNTI,则释放临时RNTI,使用新分配的RNTI。否则将临时RNTI作为新的RNTI。
需要说明的是,步骤804、步骤805和步骤806不区分先后顺序。
在本公开文本一些实施例中,一个实施例适用的场景是:切换场景。
参见图10,图中示出了非竞争随机接入过程,具体步骤如下:
步骤1001、集中处理节点向UE发送Msg0消息;
在本实施例中,根据Msg0消息内容的不同,Msg0消息的生成节点不同。
如果Msg0为RRC信令,那么由集中处理节点生成。
如果Msg0为低层信令,那么由分布式处理节点生成。
本实施例中Msg0由集中处理节点生成。Msg0的内容:可以包含接入专用码/序列或者专用接入资源。该专用码/序列或者专用接入资源可以是分布式处理节点自己分配的,也可以是由集中处理节点统一分配并通知给分布式处理节点的。不同分布式处理节点的码/序列允许有交叠。
步骤1002、UE向分布式处理节点发送Msg1消息;
UE发送Msg1消息,Msg1消息终结于分布式处理节点。Msg1消息的内容为Msg0消息分配的专用码/序列。Msg1消息传输使用的资源为Msg0消息分配的专用接入资源。
步骤1003、分布式处理节点向UE发送Msg2消息;
分布式处理节点处理UE发送的Msg1消息,并生成和Msg1消息对应的Msg2消息。
Msg2消息中包含的内容和相关技术中Msg2消息中包含的内容相同,包括UE对应的TA值、Msg3消息上行传输使用的资源、临时RNTI等信息。
Msg2消息中包含的临时RNTI的取值和集中处理节点使用的无冲突的UE标识管理方式有关。通过集中处理节点实现接入网无冲突的UE标识管理,具体可以有两种管理方式:
可选管理方式一(Alt 1):集中处理节点确定集中处理节点可用的RNTI集合,并将其中的子集分配给其管理的分布式处理节点作为分布式处理节点可用的RNTI集合,一个集中处理节点下不同分布式处理节点的RNTI不存在交叠。
可选管理方式二(Alt 2):集中处理节点确定集中处理节点可用的RNTI集合,并将该RNTI集合中的子集或者全集分配给其管理的分布式处理节点作为分布式处理节点可用,不同分布式处理节点的RNTI允许交叠,在集中处理节点可以通过TRP ID和RNTI唯一识别一个UE。
需要说明的是,无论集中处理节点实现接入网无冲突的UE标识管理使用上述哪种方法,分布式处理节点的行为是一致的,即从分布式节点可用的RNTI集合中选择一个当前未使用的RNTI作为UE的临时RNTI。
在本实施例中,UE收到Msg2消息后丢弃临时RNTI,仍然使用Msg0消息获得的C-RNTI。
在本公开文本一些实施例中,一个实施例适用的场景是:对于下行数据到达上行失步的场景。
参见图11,图中示出了非竞争随机接入过程,具体步骤如下:
步骤1101、分布式处理节点向UE发送Msg0消息;
在本实施例中,根据Msg0消息内容的不同,Msg0消息的生成节点不同。
如果Msg0消息为RRC信令,那么由集中处理节点生成。
如果Msg0消息为低层信令,那么由分布式处理节点生成。
本实施例中Msg0消息由分布式处理节点生成。Msg0消息的内容:可以包含接入专用码/序列或者专用的接入资源。该专用码/序列或者接入资源可以是分布式处理节点自己分配的,也可以是由集中处理节点统一分配并通知给分布式处理节点的。不同分布式处理节点的码/序列允许有交叠。
步骤1102、UE向分布式处理节点发送Msg1消息;
UE发送Msg1消息,Msg1消息终结于分布式处理节点。Msg1消息的内容为Msg0消息分配的专用码/序列。Msg1消息传输使用的资源为Msg0消息分配的专用接入资源。
步骤1103、分布式处理节点向UE发送Msg2消息;
分布式处理节点处理UE发送的Msg1消息,并生成和Msg1消息对应的Msg2消息。
Msg2消息中包含的内容和相关技术中Msg2消息中包含的内容相同,包括UE对应的TA值、Msg3消息上行传输使用的资源、临时RNTI等信息。
Msg2消息中包含的临时RNTI的取值和集中处理节点使用的无冲突的UE标识管理方式有关。通过集中处理节点实现接入网无冲突的UE标识管理,具体可以有两种管理方式:
可选管理方式一(Alt 1):集中处理节点确定集中处理节点可用的RNTI集合,并将其中的子集分配给其管理的分布式处理节点作为分布式处理节点可用的RNTI集合,一个集中处理节点下不同分布式处理节点的RNTI不存在交叠。
可选管理方式二(Alt 2):集中处理节点确定集中处理节点可用的RNTI集合,并将该RNTI集合中的子集或者全集分配给其管理的分布式处理节点作为分布式处理节点可用,不同分布式处理节点的RNTI允许交叠,在集中处理节点可以通过TRP ID和RNTI唯一识别一个UE。
需要说明的是,无论集中处理节点实现接入网无冲突的UE标识管理使用上述哪种方法,分布式处理节点的行为是一致的,即从分布式节点可用的RNTI集合中选择一个当前未使用的RNTI作为UE的临时RNTI。
