Description

一种非竞争随机接入中资源分配、请求发起方法及装置
本申请要求在2016年08月05日提交中国专利局、申请号为201610638511.5、发明名称为“一种非竞争随机接入中资源分配、请求发起方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信技术领域，特别涉及一种非竞争随机接入中的资源分配、接入请求的发起方法及装置。
背景技术
长期演进(Long Term Evolution，LTE)系统的随机接入分为竞争随机接入和非竞争随机接入两种。其过程分别如下：
竞争随机接入用于五个目的：1)终端初始接入；无线资源控制(Radio Resource Control，RRC)连接重建；切换；非同步状态下RRC连接态时下行数据到达；RRC连接态时上行数据到达。
图1为竞争随机接入过程示意图，如图所示，UE在RRC连接态时的定位过程主要分为四步：
Msg1：用户设备(User Equipment，UE)选择随机接入前导码(Random Access preamble)和物理随机接入信道(Physical Random Access Channel，PRACH)资源并利用该PRACH资源向基站发送所选的随机接入前导码(preamble)。
Msg2：基站接收到preamble，计算定时提前量(Time Alignment，TA)，并向UE发送随机接入响应，随机接入响应中包含该定时提前量信息和针对Msg3的上行调度信息(UL grant)，以及网络侧分配的临时小区无线网络临时标识(Cell-Radio Network Temporary Identifier，C-RNTI)。承载Msg2调度消息的物理下行控制信道(physical downlink control channel，PDCCH)用随机接入-无线网络临时标识(Random Access-Radio Network Temporary，RA-RNTI)加扰，RA-RNTI在10ms窗内与发送Msg1的时频资源唯一对应；另外Msg2中还携带前导码标识(preamble ID)，UE通过RA-RNTI和preamble ID确定该Msg2是与其发送的Msg1对应的。
Msg3：UE在Msg2指定的UL grant上发送上行传输，不同随机接入原因Msg3上行传输的内容不同，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。对于初始接入UE， 竞争解决成功后临时C-RNTI自动转化为UE在该小区的唯一UE标识C-RNTI。
图2为非竞争随机接入过程示意图，如图所示，非竞争随机接入用于切换、下行数据到达、定位和获取上行定时，其过程主要分为三步：
Msg0：基站向UE分配用于非竞争随机接入的专用preamble以及随机接入使用的PRACH资源。
Msg1：UE根据Msg0的指示，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计算上行定时提前量TA。
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、后续上行传输资源分配UL grant，定时提前量用于UE后续上行传输的定时关系。
在新一代无线网络系统(5G系统)中引入了一种新的网络架构，网络侧节点分为中央单元(Central Unit，CU)和分布式单元(Distributed Unit，DU)，用户侧节点为终端。在网络侧，一个中央单元CU控制一定区域内部署的多个分布式单元DU，这些分布式单元DU具体通过传输点发送接收节点(Transmission Reception Point，TRP)与终端进行空口传输。图3为5G网络架构示意图，图3为一个具体的由5G基站(gNB)、TRP、UE构成的5G系统架构示意，如图3所示，网络侧节点包括gNB和TRP两层实体节点控制传输，gNB是中心控制节点，TRP是直接与终端进行空口传输的网络侧传输点。一个或多个TRP可以同时为终端服务，进行数据传输。一个TRP下可以有多个波束(Beam)方向的传输，如图中TRP4下的Beam1、Beam2、Beam3。5G系统下终端在包含多个TRP的区域下可连续传输，保持终端上下文的连续性，不需要进行切换等操作，可将这个包含多个TRP的区域看做一个小区。显然，5G一个小区包含的区域范围和终端数远大于LTE系统小区的区域范围和终端数。
现有技术的不足在于：LTE系统的随机接入中，eNB通过Msg0为终端分配用于非竞争随机接入的专用preamble码和随机接入使用的PRACH资源(具体为OFDM系统中的时频资源)。在5G系统中，一个小区包含多个TRP，终端可能与多个TRP进行通信，TRP下还可能有不同的传输波束。如果采用LTE系统的非竞争接入资源分配方式，为终端分配小区内唯一的随机接入码(preamble)和时频资源(PRACH index)，5G小区内终端数非常多，显然已不能满足非竞争随机接入终端的需求。另一个问题是，在5G系统中存在双层网络节点的问题，LTE系统的非竞争接入资源分配方式(单层节点分配)无法直接应用到5G系统中。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
应理解，本发明的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、通用移动通 信系统(Universal Mobile Telecommunication System，UMTS)等。
还应理解，在本发明实施例中，用户设备(User Equipment，UE)包括但不限于移动台(Mobile Station，MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)及便携设备(portable equipment)等，该用户设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，用户设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
在本发明实施例中，基站(例如，接入点)可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。基站还可协调对空中接口的属性管理。例如，基站可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，本发明并不限定。
本发明实施例提供的技术方案意图解决在新一代无线通信系统(5G系统)中如何分配和使用随机接入资源，以使随机接入过程在5G系统中能正确进行，并实现资源的有效利用和管理。采用的方案的要点为，网络侧节点为终端分配TRP下和/或波束下唯一的随机接入码或随机接入码加上时频资源，用于非竞争随机接入中的随机接入请求。下面结合附图对本发明的具体实施方式进行说明。
在说明过程中，将分别从gNB(CU)、DU、终端侧的实施进行说明，其中gNB侧将说明资源的分配过程，DU侧将说明对随机接入请求的处理过程，终端侧将说明发起随即接入请求的过程，然后还将给出三者配合实施的实例以更好地理解本发明实施例中给出的方案的实施。这样的说明方式并不意味着三者必须配合实施、或者必须单独实施，实际上，当gNB、DU、终端分开实施时，其也各自解决gNB、DU、终端侧的问题，而三者结合使用时，会获得更好的技术效果。
在5G系统中存在双层网络节点的情况下，网络侧节点包括gNB和TRP两层实体节点控制传输，gNB是中心控制节点，TRP是直接与终端进行空口传输的网络侧传输点，因此，在具体说明过程中，将主要以gNB，DU将以TRP，终端将以UE为例进行说明。
图4为网络侧非竞争随机接入中的资源分配方法实施流程示意图，如图所示，可以包括：
步骤401、在网络侧为终端分配在非竞争随机接入中用于随机接入请求的资源，所述资源包括以下一项或多项：随机接入码，终端发起随机接入的时频资源，随机接入请求针 对的TRP ID，发送随机接入请求的beam ID；
步骤402、将包含所述资源的消息通知所述终端。
图5为终端侧发起非竞争随机接入请求的方法实施流程示意图，如图所示，可以包括：
步骤501、在终端上接收网络侧发送的随机接入指示消息，所述消息中携带有网络侧为终端分配的在非竞争随机接入中用于随机接入请求的资源，所述资源包括以下一项或多项：随机接入码，终端发起随机接入的时频资源，随机接入请求针对的TRP ID，发送随机接入请求的beam ID；
步骤502、根据该资源发起随机接入请求。
实施中，在网络侧节点上，负责分配非竞争接入资源的网络侧节点可以是gNB或TRP，也即指示终端根据所述资源发起随机接入的可以是gNB，也可以是TRP，其中，gNB决策指示终端发起随机接入的将在实施例1-4中以实例说明，TRP决策指示终端发起随机接入的将在实施例5-8中以实例说明。
实施中，将包含所述资源的消息通知终端，是通过物理层控制命令或高层RRC信令通知的。
具体的，网络侧节点为终端分配非竞争接入资源的命令(携带非竞争随机接入资源分配消息)方式可以为：物理层控制命令(主要用于在本TRP下或小区内发起随机接入)；或高层RRC信令(主要用于跨TRP发起随机接入或跨小区发起随机接入)。
实施中，资源对于UE发起随机接入请求时请求的TRP或使用的波束是唯一的。
具体实施中，使所述资源对于UE发起随机接入请求时请求的TRP或使用的波束而言是唯一的方式包括以下方式之一或者其组合；
在生成随机接入码后为每个TRP分配随机接入码，TRP仅在终端使用归属于自己的随机接入码发起随机接入请求时进行响应；具体将在实施例1、5中以实例说明。
基于每个TRP ID生成随机接入码，TRP仅在终端使用基于自己生成的随机接入码发起随机接入请求时进行响应；具体将在实施例2、6中以实例说明。
在生成随机接入码后为每个TRP的各波束分配随机接入码，TRP仅在终端使用归属于自己的随机接入码且在指定波束上发起随机接入请求时进行响应；具体将在实施例3、7中以实例说明。
基于每个波束ID或每个TRP的每个波束ID生成随机接入码，TRP仅在终端使用基于该波束ID生成的随机接入码且在指定波束上发起随机接入请求时进行响应。具体将在实施例4、8中以实例说明。
从上述方案可以看出，小区内的preamble码和时频资源在不同TRP下可复用，如果 一个TRP下有多个波束，不同波束下的preamble码和时频资源还可复用。这样大大增加了随机接入资源的使用效率，增加了可唯一识别的非竞争随机接入请求用户数，使得在5G系统下能有效进行随机接入过程。
具体的，非竞争随机接入资源分配消息的内容可以包括以下一项或多项的组合：
消息内容1：Preamble ID或(preamble ID+PRACH index)；
消息内容2：该非竞争随机接入生效的TRP ID；
消息内容3：该非竞争随机接入生效的beam ID。
可能的组合方式可以如下：
(1)消息内容1，即Preamble ID或(preamble ID+PRACH index)；
(2)消息内容1+2，即(Preamble ID或(preamble ID+PRACH index))+TRP ID；
(3)消息内容1+2+3，(Preamble ID或(preamble ID+PRACH index))+TRP ID+beam ID。
消息内容1与LTE系统的非竞争随机接入资源指示消息内容相同，但在具体实施中，结合具体信令过程和节点间关系，使用方法和效果不同。
非竞争随机接入资源分配消息为实际发送的终端的网络侧命令(物理层信令或RRC消息)中携带的消息，该消息发送给终端后，如何理解和使用详见以下实施例。

实施例一：
本实施例中，由gNB为终端分配特定TRP下的非竞争随机接入资源，例中，preamble码序列生成与具体的TRP不相关，preamble序列在小区中的所有TRP都可解析。但gNB为相邻TRP划分不同的非竞争随机接入preamble组及其可用时频资源。同时，本TRP和相邻TRP用于非竞争随机接入的preamble组不能用于竞争随机接入。
