一种下行数据传输方法及装置

本申请主张在2016年7月27日在中国提交的中国专利申请号No.201610601767.9的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种下行数据传输方法及装置。
背景技术
随着无线通信系统的发展，终端类型和业务类型多样化，终端省电、节约网络资源和满足各种业务类型的需求并存。为了同时保证终端省电和快速数据传输，引入一种终端状态Inactive(不活跃)态。在这种状态下，终端保持核心网连接，但没有空口连接，即不与特定小区有随时可以进行数据传输的连接关系。Inactive态下的终端不与特定小区关联，网络侧只知道终端的区域范围，不能直接进行空口调度传输。
在Inactive状态下，网络侧为终端分配一定区域内有效的RAN(Radio Access Network，无线接入网)标识：inactive UE ID(不活跃用户设备标识)，也可以称为resume ID，用以在inactive态下识别终端。网络可以利用该标识在查找终端或终端主动发起上行接入时用该标识作为身份识别进入连接态。该标识不同于全球唯一的IMSI(International Mobile Subscriber Identification Number，国际移动用户识别码)或连接态终端标识C-RNTI(Cell Radio Network Temporary Identifier)，该标识长度介于IMSI和C-RNTI两者之间(例如inactive UE ID长度为40bit，C-RNTI长度为16bit)，且该标识只在包含多个小区或多个eNB的一定区域内有效，如果超过该区域，终端需要更新inactive UE ID。
在相关的终端状态中，网络侧除了为处于RRC(Radio Resource Control，无线资源控制)连接态的终端分配了终端空口传输唯一标识C-RNTI可以直接进行数据收发外，对于处于其他状态的终端，如果有数据需要传输时，终端都要先进入RRC连接态，并在建立RRC连接来获取用于数据传输的终端空口传输唯一标识即C-RNTI后，才能进行后续的数据传输。因此，这种过程 不利于有数据到达时的快速传输，造成了一定的数据传输时延。

具体实施方式
下面将结合附图和实施例，对本公开的具体实施方式作进一步详细描述。以下实施例用于说明本公开，但不用来限制本公开的范围。
本公开实施例的方案可以用于不同的网络部署结构，为了描述方便，在此先介绍两种未来移动通信可能采用的网络部署结构。
部署结构一：基站+终端
如图1所示是典型的LTE(Long Term Evolution，长期演进)架构。在这种架构下，eNB下有多个小区(cell)，连接态的终端UE与小区进行空口数据收发，连接态的UE分配有小区内唯一的UE标识C-RNTI。
部署结构二：网络侧节点分为中央单元(CU，Central Unit)和分布式单元(DU，Distributed Unit)，用户侧节点为终端。
如图2所示，是未来移动通信5G可能采用的一种架构。在这种架构下，网络侧节点包括中央单元和分布式单元，一个中央单元控制一定区域内部署的多个分布式单元，这些分布式单元具体通过传输点TRP(Transmission Reception Point)与终端进行空口传输。一个或多个传输点可以同时为终端服务，进行数据传输。在这种架构下，都需要通过网络侧为终端分配终端空口唯一标识来进行数据调度和传输，这个标识可以是C-RNTI或TRP-RNTI。
后续实施例中为统一描述，将用于连接态的终端的传输的终端唯一标识称为终端空口传输唯一标识，该标识在传统LTE中即为C-RNTI。Inactive态的终端在区域内唯一标识称为inactive UE ID。网络侧无线信令和数据收发节点不管是部署结构一中的eNB或部署结构二中的CU/DU(具体收发点为TRP)，都统称为基站。
当有下行数据需要发送时，为快速发送数据，减小数据传输的时延，本公开实施例的核心思想是：当有下行数据需要发送给未与单个小区建立连接的终端时，区域内的一个或多个基站向所述终端发送寻呼消息，通知所述终端接收下行数据。随后，终端接收一个或多个基站发送的寻呼消息，接收所述一个或多个基站中的第一基站发送的下行数据。其中，该第一基站可以是一个或多个基站中的任意一个或者多个基站，或者还可以指的是接收到终端的寻呼反馈消息的基站。
其中，未与单个小区建立连接是指：新引入的终端状态，即不活跃的连接态(inactive状态)，在该状态下允许如下的行为：
(1)核心网与RAN网络侧节点(如基站、CU)保持全部或部分连接(如只保持控制面连接而不保持用户面连接)；(2)移动性是UE执行的，在网络侧预配置的区域内，通过小区重选来执行小区间移动，而不采用切换过程来进行小区间移动；(3)终端被分配了在网络侧预配置的区域内的唯一用户标识inactive UE ID(或resume ID)其中，该预配置区域包含一个或多个基站中的多个小区，为终端在移动性简化的同时带来移动性自由度。
一个或多个基站是指：该终端inactive UE ID有效区域内的所有基站，或者如果能确定终端大致位置，该大致位置内inactive UE ID有效区域内的所有基站(即为inactive UE ID有效区域全部基站的子集)。
终端inactive UE ID有效区域内一个或多个基站向该终端发送寻呼消息，寻呼消息中携带以下一个或多个信息：
(1)终端的inactive UE ID，用于标识终端身份。
(2)基站对终端进行下行数据调度和传输的空口标识(可选)。具体为：
(21)为终端分配的终端空口传输唯一标识，如C-RNTI，或
(22)用于为多个终端进行下行数据调度和传输的公共空口传输标识， 如CB-RNTI(Contention-Based RNTI)。
其中，该多个终端共用的空口传输标识也可以采用预配置、或协议规定、或系统消息广播的方式确定。
(3)终端接收下行数据指示(可选)。
该信息的目的是通知终端接收后续下行传输，可替换的方式是如果基站为终端分配了用于下行数据调度和传输的空口标识，则认为终端需要接收后续下行传输，“终端接收下行数据指示”可不出现。
(4)公共资源配置信息(可选)。
如果配置了公共资源，终端只在该资源范围内接收下行数据调度和传输，否则，在当前小区可用的所有下行资源上接收下行数据调度和传输。
(5)终端用于反馈基站寻呼消息的资源(可选)。其中，终端反馈的方式包括：
方式1：专用上行接入序列码和序列码的时频资源位置(如无时频资源位置指示则为该小区所有可用专用上行接入序列码传输资源位置)；
方式2：与该寻呼消息对应的HARQ(Hybrid Automatic Repeat Request，混合自动重传请求)反馈资源，如与该寻呼消息时频资源位置对应的具体资源位置上的反馈序列码。采用方式2时也可以不用基站指示，用协议规定的方式，规定终端反馈该基站寻呼消息的HARQ反馈序列及其位置，注意这里只有ACK反馈，没有NACK反馈。
下行数据传输是指：如果寻呼消息中为该终端分配了终端空口传输唯一标识，基站和终端用终端空口传输唯一标识进行下行数据调度和传输。如果终端只有公共空口传输标识可用，下行调度用公共空口传输标识调度，下行传输中携带需要传输的下行数据和该终端的inactive UE ID(用于唯一标识终端)。此时，可能有多个终端同时接收基站发送的下行传输，终端从中解出inactive UE ID进行识别，从而确定下行数据是否是发送给该终端的。
终端如果没对寻呼消息进行反馈，基站需要在发送寻呼消息的所有小区为终端进行下行数据传输；如果终端对寻呼消息进行了反馈，基站可以在接收到终端对寻呼反馈的小区进行下行数据传输。
终端随后接收下行数据传输是指终端根据寻呼消息中的inactive UE ID 确定身份，并根据寻呼消息中携带的信息接收下行数据调度和传输。如果基站指示了寻呼反馈资源，则终端收到寻呼消息后进行寻呼消息反馈，接收到寻呼消息反馈的基站为该终端发送下行数据传输；如果基站未指示寻呼反馈资源，发送寻呼消息的基站随后为终端发送下行数据传输。
以下，结合包括不同内容的寻呼消息，对本公开实施例的下行数据传输方法进行详细描述。
在下面提到的第一个实施例到第四个实施例中，寻呼消息中携带inactive UE ID和对该终端分配的C-RNTI，同时还可携带其他可选的信息。在寻呼消息相同的子帧或有对应时间关系的子帧或随后的任意子帧，基站用C-RNTI为该终端分配下行资源并在该下行资源上发送给该终端的下行数据。
在下面提到的第五个实施例到第八个实施例中，寻呼消息中携带inactive UE ID和对多个终端共用的CB-RNTI，同时还可携带其他可选的信息。在寻呼消息相同的子帧或有对应时间关系的子帧或随后的任意子帧，基站用CB-RNTI为该终端分配下行资源并在该下行资源对该终端发送下行传输，下行传输中包括携带inactive UE ID的层2控制单元(如携带inactive UE ID的MAC CE)和发送给该终端的下行数据。
