Description

一种端到端用户动态复用蜂窝用户资源的方法及基站
技术领域
本发明涉及无线通信技术领域， 具体地说， 涉及一种端到端 ( Device-to-Device，简称为 D2D )用户动态复用蜂窝用户资源的方法及基站。 背景技术
D2D通信是一种在蜂窝系统的控制下， 允许终端之间通过复用小区内资 源直接进行通信的新型技术。 它具有提高系统频谱利用率、 减少终端电池消 耗从而节省移动台功率、 降低蜂窝小区基站的负载、 改善系统用户公平性、 提高网络服务质量、 巩固下层结构及提供新的服务等优点， 且能在一定程度 上解决无线通信系统频谱资源匮乏的问题。
在蜂窝网络架构下， D2D通信通过共享小区资源来达到系统整体性能的 提升。若 D2D用户被分配到正交的信道资源时，则不会对蜂窝网络中的其它 用户造成干扰； 若 D2D用户被分配到非正交的信道资源， 即 D2D用户与其 它蜂窝用户共用信道资源时， D2D用户和蜂窝用户之间可能会形成干扰， 严 重时可能会造成蜂窝用户通信的中断。
如图 1所示， 蜂窝网络下有一对用户 D1和 D2在进行 D2D通信， 刚开 始由于用户 U1与 D2D用户间的距离较远， 蜂窝网络指定 D2D用户共享 U1 的资源， 此时 D2D与蜂窝网络间不会造成干扰。 当蜂窝用户 U1移动到距离 D2D用户较近的位置时 （或者当 D2D用户发生移动导致 D2D用户和 U1距 离较近时） ， 由于 U1与 D2D用户所占用的资源相同， 它们之间就会出现干 扰。 如果干扰严重影响到 U1用户的正常通信， 蜂窝网络一般会优先保证蜂 窝用户 U1的通信， D2D用户则可能会被要求切换到蜂窝网络下进行通信， 因此可能会出现 D2D用户频繁发生切换的现象。 由于蜂窝用户及 D2D用户 的移动不可预知性， 因此上述问题很难避免。 发明内容 本发明的目的是提供一种 D2D 用户动态复用蜂窝用户资源的方法及基 站， 以避免由于 D2D用户与共享资源的蜂窝用户间信道条件发生改变（例如 在通信过程中彼此靠近 )时， 由于相互干扰而使 D2D用户被迫频繁发生切换 的问题。

本发明实施例一方面可以避免 D2D用户在 D2D通信和蜂窝通信之间进 行频繁的切换， 另外一方面由于最大限度的复用了蜂窝网络的资源， 因此也 极大的提高了蜂窝网络的传输效率。 附图概述
图 1 为一个 LTE蜂窝网络下允许 D2D通信的实例；
图 2为本发明实施例中端到端用户动态复用蜂窝用户资源的方法流程图； 图 3 为本发明实施例中基站侧具体处理流程图；
图 4 为本发明实施例中蜂窝用户、 D2D用户和基站间交换消息的流程图。 本发明的较佳实施方式
下文中将结合附图对本发明的实施例进行详细说明。 需要说明的是， 在 不冲突的情况下， 本申请中的实施例及实施例中的特征可以相互任意组合。
下面的实施例以 LTE( Long Term Evolution,长期演进）及 LTE- Advanced (演进的 LTE )蜂窝网络下整合 D2D通信进行说明， 但本发明所涉及的技 术不限于 LTE及 LTE- Advanced蜂窝网络系统，还可以是 WCDMA( Wide band Code Division Multiple Access, 宽带码分多址） 、 CDMA2000、 TD-SCDMA ( Time Division- Synchronous Code Division Multiple Access , 时分同步码分多 址）、 GSM ( Global System for Mobile Communications, 全球移动通信系统） 以及其它的无线接入蜂窝网络系统。 在本实施例中， 一种端到端用户动态复用蜂窝用户资源的方法， 应用于 基站侧， 如图 2所示， 包括：
在确认服务范围内的端到端用户对其他蜂窝用户造成干扰时， 为该端到 端用户分配符合该端到端用户的服务质量要求、 且未对其他蜂窝用户造成干 扰的资源， 并指示该端到端用户使用新分配的资源。
如图 3所示，具体的处理过程是在基站发现有 D2D干扰时开始启动，基 站发现 D2D干扰过程可以基于蜂窝用户的上报或者基站自身的检测。所述基 站侧处理过程可以分为以下步骤：
步骤 1 : 基站首先检测是否有空闲的资源可满足 D2D上报的 QoS要求； 步骤 2: 如果检测结果为是， 则执行步骤 6, 直接通知 D2D用户更新到 该空闲资源上； 否则， 执行步骤 3 ;
步骤 3： 基站向蜂窝用户和 D2D用户广播探测指示消息；
一种实现方式时， 在该探测指示消息中携带 D2D探测所用的信息资源， 所述信息资源可包括时序和频率位置等； 为便于传统蜂窝用户的接收， 基站 广播的 D2D探测所用的信息资源优先选择下行资源，例如可以占用物理下行 控制信道（PDCCH, Physical downlink control channel )等。 如果蜂窝网路中 的用户都支持 D2D传输， 也可以选择上行资源；
另一种实现方式是，如果蜂窝用户和 D2D用户支持专用的探测信息资源 , 则在该探测指示消息中仅携带探测指示标识， 该探测指示标识用于指示蜂窝 用户和 D2D用户进行探测准备，在该探测指示消息中不需要额外携带探测所 用的信息资源。
步骤 4: 基站接收蜂窝用户上报的探测结果， 该探测结果用于指示该蜂 窝用户是否在 D2D用户附近及是否存在潜在的干扰风险；
步骤 5：基站基于接收到的探测结果及 D2D用户上报的所需的 QoS要求， 为 D2D用户分配新的资源；
步骤 6: 通知 D2D用户更新资源。
图 4是蜂窝用户、 D2D用户和基站间交换消息的过程。 依然以图 1所示 的蜂窝网络系统为例。其中，将基站标记成 E1 ,将蜂窝用户标记成 C— UE1 , ... , C UE10, 将 D2D用户标记成 D2D— D1和 D2D— D2.
基站向蜂窝网络用户和 D2D用户广播探测所用的信息资源。为便于传统 蜂窝用户接收， 探测所用的信息资源优先选择下行资源。 如果根据各用户在 接入时发来的注册信息，判断出蜂窝网络中的用户都支持 D2D传输，也可以 选择上行资源作为探测所用的信息资源。
D2D用户在接收到基站发过来的探测所用的信息资源后， 占用指定的资 源广播其探测信号。 蜂窝用户根据基站发过来的探测所用的信息资源， 在相 应的信息资源上侦听来自 D2D用户的探测信号。蜂窝用户可以通过侦听探测 信号来判断 D2D用户是否在附近及是否存在潜在的干扰风险。
蜂窝用户将侦听到的探测结果上报至基站。 上报的探测结果可以只是指 示是否存在干扰。例如蜂窝用户一旦探测到 D2D发出的探测信号的功率值超 过设定的阔值， 则触发在上行信道上报探测结果至基站。 如果蜂窝用户无法 探测到 D2D用户发出的探测信号或者探测到的 D2D用户发射的探测信号的 功率值小于设定的阔值， 则不触发上报探测结果至基站。 在另一实施例中， 上报的探测结果还可以包括探测到 D2D用户发射的探测信号的功率水平；其 中， 在该探测结果中， 只用 1比特信息指示是否存在干扰， 使用附加比特信 息以指示探测到探测信号的功率值。
基站基于接收到的探测结果及 D2D用户上报的所需的 QoS要求， 为该 D2D用户分配新的资源。基站根据探测结果将无干扰风险的蜂窝用户的资源 作为 D2D用户的备选资源。如果该备选资源同时可满足 D2D用户上报的 QoS 要求， 则可将该备选资源作为 D2D用户的优选资源，通过更新资源消息分配 给 D2D用户使用。
D2D用户在接收到基站发来的更新资源消息后， 将原有资源释放并按照 基站分配的新资源进行通信。
此外， 在本实施例中， 一种基站， 包括：
资源分配模块， 用于在确认服务范围内的端到端用户对其他蜂窝用户造 成干扰时， 为所述端到端用户分配符合该端到端用户的服务质量要求、 且未 对其他蜂窝用户造成干扰的资源；

较佳地，

较佳地，
所述资源分配模块接收到的测量结果中还携带有所述蜂窝用户探测到的 端到端用户发射的探测信号的功率值。
本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序 来指令相关硬件完成， 所述程序可以存储于计算机可读存储介质中， 如只读 存储器、 磁盘或光盘等。 可选地， 上述实施例的全部或部分步骤也可以使用 一个或多个集成电路来实现。 相应地， 上述实施例中的各模块 /单元可以釆用 硬件的形式实现， 也可以釆用软件功能模块的形式实现。 本发明不限制于任 何特定形式的硬件和软件的结合。

工业实用性
本发明实施例一方面可以避免 D2D用户在 D2D通信和蜂窝通信之间进 行频繁的切换， 另外一方面由于最大限度的复用了蜂窝网络的资源， 因此也 极大的提高了蜂窝网络的传输效率。
