Description

设备到设备通信系统的通信方法、 装置及系统 技术领域 本发明涉及通信领域, 具体而言, 涉及一种设备到设备通信系统的通信方法、 装 置及系统。 背景技术 在蜂窝通信系统中, 当两个用户设备 (User Equipment, 简称为 UE) 之间有业务 传输时, 例如, 用户设备 1 (UE1 ) 到用户设备 2 (UE2) 的业务数据, 首先通过空口 传输给 UE1所在小区的基站(Base Station,或者称为 Node B, 或演进(evolved) Node B),该基站通过核心网将该用户数据传输给 UE2所在小区的基站, 该基站再将上述业 务数据通过空口传输给 UE2。 UE2到 UE1的业务数据传输采用类似的处理流程。如图 1所示,当 UE1和 UE2位于同一个蜂窝小区,虽然两个 UE由同一个基站的小区覆盖, 数据传输时仍然需要通过核心网中转, 并且一次数据传输仍然会消耗两份无线频谱资 源。 由此可见, 如果用户设备 1和用户设备 2位于同一小区并且相距较近, 那么上述 的蜂窝通信方法显然不是最优的。 而实际上, 随着移动通信业务的多样化, 例如, 社 交网络、 电子支付等应用在无线通信系统中的普及, 使得近距离用户之间的业务传输 需求日益增长。 因此, 设备到设备 (Device-to-Device, 简称为 D2D) 的通信模式日益 受到广泛关注。 如图 2所示, D2D是指业务数据不经过基站和核心网的转发, 直接由 源用户设备通过空口传输给目标用户设备。 对于近距离通信的用户来说, D2D不但节 省了无线频谱资源, 而且降低了核心网的数据传输压力。 在蜂窝通信中, 当两个 UE进行通信时, 一般情况下 UE自身不会知道对方 UE的 位置, 而是通过网络侧设备 (例如基站或者核心网设备) 建立起两个 UE的连接。 而 对于设备到设备通信来说, 建立通信的前提是 UE之间的相互发现。但在相关技术中, 针对 UE如何发现与之邻近的 UE的问题 (或者也可称为同伴发现), 目前尚未提出有 效的解决方案。 发明内容 针对相关技术中 UE如何发现与之相邻的 UE的问题, 本发明实施例提供了一种 设备到设备通信系统的通信方法、 装置及系统, 以至少解决上述问题。 根据本发明的一个实施例, 提供了一种设备到设备通信系统的通信装置, 位于第 一用户设备, 所述装置包括: 第一接收模块, 设置为接收来自网络侧的配置消息, 其 中, 所述配置消息中携带有设备到设备通信发现信号的配置信息;

Evolution) /LTE-A (LTE- Advanced) 蜂窝通信系统为例, 对本发明实施例的技术方案 进行说明。 LTE/LTE-A系统下行链路以正交频分复用 (Orthogonal Frequency Division Multiplexing, 简称为 OFDM) 技术为基础, 上行链路则采用单载波频分多址 (Single carrier-Frequency Division Multiplexing Access, 简称为 SC-FDMA ) 方式。 在 OFDM/SC-FDMA系统中, 通信资源是时-频两维的形式。例如, 对于 LTE/LTE-A系统 来说, 上行和下行链路的通信资源在时间方向上都是以帧(frame) 为单位划分, 如图 10所示, 每个无线帧 (radio frame) 长度为 10 ms, 包含 10个长度为 1 ms的子帧 (sub-frame), 每个子帧又包括长度为 0.5ms的两个时隙 (slot)。 在频率方向, 资源以子载波 (subcarrier) 为单位划分, 具体在通信中, 频域资源 分配的最小单位是资源块(Resource Block, 简称为 RB), 对应物理资源的一个物理资 源块(Physical RB, 简称为 PRB)。 如图 11所示, 一个 PRB在频域包含 12个子载波, 对应于时域的一个时隙。 每个 OFDM 符号上对应一个子载波的资源称为资源单元 ( Resource Element, 简禾尔 RE )。 在 LTE/LTE-A蜂窝通信中, UE通过检测同步信号 (Synchronization Signal, 简称 为 SS) 发现 LTE小区。 同步信号包括有主同步信号 (Primary SS, 简称为 PSS) 和辅 同步信号(Secondary SS, 简称为 SSS)。 UE通过检测同步信号, 获得下行链路的中心 频点, 以及获得与基站的下行同步。 并且, 由于同步信号携带有物理小区标识, 检测 同步信号也意味着 UE"发现" LTE/LTE-A小区。 在上行链路, 当 UE有上行数据传输时, 需要发起随机接入 (Random Access, 简 称为 RA) 进行上行同步, 并且从 RRC (Radio Resource Control, 简称为 RRC) 空闲 (Idle) 状态进入连接 (Connected) 状态。 随机接入时 UE 需要发送随机接入前导 (preamble), 网络侧通过在特定的时频资源中盲检测随机接入前导, 实现对 UE的识 别和上行链路的同步。 在 D2D通信时, 也存在类似的问题, 即进行 D2D通信的 UE首先需要实现相互 的发现 (和识别)。 下面通过具体实施例进行说明。 实施例一 图 12是本实施例中 D2D同伴发现的信令流程图。 如图 12所示, 在本实施例中, D2D同伴发现主要包括以下步骤: 步骤 S1201 , 网络设备 (相当于上述的网络侧) 发送配置消息。 该配置消息用于 指示同伴发现的配置, 可以包括以下参数的一个或多个: (1 ) 发现信号集合, 用于指 示可用的 D2D通信发现信号; (2) 资源配置参数, 用于指示可以传输 D2D通信发现 信号的子帧位置和 /或资源块位置。 上述配置消息可以是以广播的形式发送。 例如, 上述配置消息可以承载于系统信 息块 (System Information Block, 简称为 SIB) 中以无线资源控制 (Radio Resource Control, 简称为 RRC) 信令的方式传输, 可以是重用系统中原有的 SIB, 或者是增加 新的用于 D2D通信的 SIB。 本实施例中的网络设备可以是基站,例如, 3GPP所定义的 eNB,该 eNB包括 Relay, 或者网络中的其他低功率节点。 该网络设备也可包括其他网元, 比如移动性管理实体 (Mobility Management Entity, 简称为 MME), 或者其他核心网的网元。 步骤 S1202, D2D用户设备检测上述的配置消息。 如果用户设备的被发现功能开 启, 即设置为可被发现时, 该用户设备可以以图 12中所示的目标用户设备(相当于上 述的第二用户设备)的身份工作。例如,在配置消息所指示的同伴发现资源中发送 D2D 通信发现信号。 如果用户设备有同伴发现的需求,则该用户设备可以以图 12中所示的源用户设备 (相当于上述的第一用户设备) 的身份工作。 例如, 在配置消息所指示的同伴发现资 源中检测 D2D通信发现信号。 上述的 D2D通信发现信号可以是配置消息中发现信号集合中指示的 D2D通信发 现信号。 或者, D2D 通信发现信号携带有目标标识信息 (ID), 该标识可以是临时标 识, 为用户设备从网络侧获得的用于 D2D通信或 D2D通信同伴发现的标识。 步骤 S1203, 对于源用户设备来说, 检测到 D2D通信发现信号后, 则表示在其邻 近区域有其他可被发现的用户设备;源用户设备基于检测到 D2D通信发现信号向网络 请求发送该 D2D通信发现信号的目标用户设备的身份信息。例如, 源用户设备向网络 设备发送请求消息。该请求消息中包括有源用户设备检测到的 D2D通信发现信号的标 识, 例如 D2D通信发现信号序列索引; 还可包括有检测到该 D2D通信发现信号的资 源位置, 例如子帧位置和资源块位置。 或者, 该同伴发现请求中包括有源用户设备检 测到的 D2D通信发现信号中的标识信息。 步骤 S1204, 接收到源用户设备发送的同伴发现请求后, 网络设备处理该请求。 例如, 网络设备发送寻呼消息, 该寻呼消息中包括有目标用户设备发送的 D2D通信发 现信号的标识, 该标识如前所述; 或者, 该寻呼消息中同时包括有该 D2D通信发现信 号的传输资源位置, 例如子帧位置和资源块位置。 或者, 该同伴发现请求中包括有标 识信息, 即源用户设备检测到的 D2D通信发现信号中携带的标识信息。 步骤 S1205, 目标用户设备发送 D2D通信发现信号后, 会监听(monitor)寻呼信 道。 当在寻呼信道中检测到自己所发送的 D2D通信发现信号的标识; 或者检测到自己 所发送的 D2D通信发现信号标识,并且该 D2D通信发现信号对应的 D2D通信发现信 号传输资源与自己传输 D2D通信发现信号资源相同; 或者检测到前述标识信息时, 向 网络设备做出响应消息。 响应消息表示目标用户设备是否同意被发现。 当同意时, 可 以包括有目标用户设备的身份信息。 该身份信息可以是应用层标识。 进一步的, 在做出响应消息之前, 网络设备会将源用户设备的身份信息告知目标 用户设备, 目标用户设备根据源用户设备的身份确定是否同意被发现。 上述的寻呼信道可以是为 D2D通信或 D2D同伴发现设置的专用寻呼信道。 步骤 S1206, 接收到目标用户设备发送的响应消息后, 网络侧设备向源用户设备 发送应答消息。 该应答消息包括目标用户设备的身份信息; 或者, 当同伴发现被拒绝 时, 该应答消息中包括用于表示同伴发现被拒绝的标识信息。 发送同伴发现请求后, 源用户设备等待接收网络设备发送的应答消息; 并根据上 述应答消息的内容确定同伴发现是否成功。 进一步的, 当检测到 D2D通信发现信号时, 如果源用户设备处于空闲 (idle, 例 如 RRC idle) 状态时, 源用户设备需要先发起连接建立请求, 与网络侧建立连接 (例 如 RRC连接), 进入连接 (connected) 状态, 再向网络侧发送同伴发现请求。 进一步的,当检测到寻呼消息时,如果目标用户设备处于空闲(idle,例如 RRC idle) 状态时,目标用户设备需要先发起连接建立请求,与网络侧建立连接(例如 RRC连接), 进入连接 (connected) 状态, 再向网络侧发送响应消息。 实施例二 本实施例与实施例一的区别在于, 在本实施例中, 源用户设备发起同伴发现请求 前, 先发送 D2D通信发现触发信号, 目标用户设备在接收到 D2D通信发现触发信号 后, 再发送 D2D通信发现信号。 图 13为本实施例 D2D同伴发现的信令流程图, 如图 13所示, 本实施例中 D2D 同伴发现主要包括以下步骤: 步骤 S1301 , 网络设备 (即网络侧) 发送配置消息, 其中, 配置消息中包括 D2D 通信发现信号的配置信息和 D2D通信发现触发信号的配置信息。 D2D通信发现信号 的配置信息包括以下参数的一个或多个: (1 )发现信号集合, 用于指示可用的 D2D通 信发现信号; (2) 资源配置参数, 用于指示 D2D通信发现信号传输的子帧位置和 /或 资源块位置。 D2D通信发现触发信号的配置信息包括以下参数的一个或多个: ( D D2D 通信发现触发信号集合,用于指示可用的 D2D通信发现触发信号; (2)资源配置参数, 用于指示 D2D通信发现信号传输的子帧位置和 /或资源块位置。 或者, 配置消息中包括资源配置参数, 指示 D2D通信发现信号和 /或 D2D通信发 现触发信号传输的子帧位置和 /或资源块位置; 还包括 D2D通信发现触发信号的配置 信息, 指示可用的 D2D通信发现触发信号集合。 上述配置消息可以是以广播的形式发送。 例如, 上述配置消息承载于系统信息块
(SIB)中传输,可以是重用系统中原有的 SIB,或者是增加新的用于 D2D通信的 SIB。 本实施例中的网络设备可以是基站,例如 3GPP所定义的 eNB,该 eNB包括 Relay, 或者网络中的其他低功率节点。 该网络设备也可包括其他网元, 比如 MME, 或者其 他核心网的网元。 步骤 S1302, 对于 D2D用户设备来说, 检测上述的配置消息。 如果用户设备有同 伴发现的需求, 则该用户设备可以以图 13中所示的源用户设备(即上述的第一用户设 备)的身份工作。例如, 在配置消息所指示的 D2D通信发现触发信号资源中发送 D2D 通信发现触发信号。 在发送 D2D通信发现触发信号后, 源用户设备监听 D2D通信发 现信号。 上述的同伴发现触信号可以是配置消息所指示的 D2D 通信发现触发信号集合中 的信号。 步骤 S1303, 如果用户设备的被发现功能开启, 即设置为可被发现时, 该用户设 备可以以图 13中所示的目标用户设备 (即相当于上述的第二用户设备) 的身份工作。 例如, 在配置消息所指示的 D2D通信发现触发信号资源中检测 D2D通信发现触发信 号。 检测到 D2D通信发现触发信号后, 该用户设备在 D2D通信发现信号中发送 D2D 通信发现信号。 上述的 D2D通信发现信号可以是配置消息中发现信号集合中指示的 D2D通信发 现信号。 或者, D2D 通信发现信号携带有目标标识信息 (ID), 该标识可以是临时标 识, 为用户设备从网络侧获得的用于 D2D通信或 D2D通信同伴发现的标识。 步骤 S1304, 对于源用户设备来说, 检测到 D2D通信发现信号后, 则表示在其邻 近区域有其他可被发现的用户设备;源用户设备基于检测到 D2D通信发现信号向网络 请求发送该 D2D通信发现信号的目标用户设备的身份信息。例如, 源用户设备向网络 设备发送请求消息。该请求消息中包括有源用户设备检测到的 D2D通信发现信号的标 识, 例如, D2D通信发现信号序列索引; 还可包括有检测到该 D2D通信发现信号的 资源位置, 例如子帧位置和资源块位置。 或者, 该同伴发现请求中包括有源用户设备 检测到的 D2D通信发现信号中的标识信息。 步骤 S1305, 接收到源用户设备发送的同伴发现请求后, 网络设备处理该请求。 例如, 网络设备发送寻呼消息, 该寻呼消息中包括有目标用户设备发送的 D2D通信发 现信号的标识, 该标识如前所述; 或者, 该寻呼消息中同时包括有该 D2D通信发现信 号的传输资源位置, 例如子帧位置和资源块位置。 或者, 该寻呼消息中包括有标识信 息, 即源用户设备检测到的 D2D通信发现信号中携带的标识信息。 步骤 S1306, 目标用户设备发送 D2D通信发现信号后, 会监听(monitor)寻呼信 道。 当在寻呼信道中检测到自己所发送的 D2D通信发现信号的标识; 或者检测到自己 所发送的 D2D通信发现信号标识,并且该 D2D通信发现信号对应的 D2D通信发现信 号传输资源与自己传输 D2D通信发现信号资源相同; 或者检测到前述标识信息时, 向 网络设备做出响应消息。 响应消息表示目标用户设备是否同意被发现。 当同意时, 可 以包括有目标用户设备的身份信息。 该身份信息可以是应用层标识。 进一步的, 在做出响应消息之前, 网络设备会将源用户设备的身份信息告知目标 用户设备, 目标用户设备根据源用户设备的身份确定是否同意被发现。 上述的寻呼信道可以是为 D2D通信或 D2D同伴发现设置的专用寻呼信道。 步骤 S1307, 接收到目标用户设备发送的响应消息后, 网络侧设备向源用户设备 发送应答消息。 该应答消息包括目标用户设备的身份信息; 或者, 当同伴发现被拒绝 时, 该应答消息中包括用于表示同伴发现被拒绝的标识信息。 发送同伴发现请求后, 源用户设备等待接收网络设备发送的应答消息; 并根据上 述应答消息的内容确定同伴发现是否成功。 进一步的, 当检测到 D2D通信发现信号时, 如果源用户设备处于空闲 (idle, 例 如 RRC idle) 状态时, 源用户设备需要先发起连接建立请求, 与网络侧建立连接 (例 如 RRC连接), 进入连接 (connected) 状态, 再向网络侧发送同伴发现请求。 进一步的,当检测到寻呼消息时,如果目标用户设备处于空闲(idle,例如 RRC idle) 状态时,目标用户设备需要先发起连接建立请求,与网络侧建立连接(例如 RRC连接), 进入连接 (connected) 状态, 再向网络侧发送响应消息。 相比于实施例一, 本实施例中增加了 D2D通信发现触发信号, 可以达到降低功率 浪费的目的, 比如, 目标用户设备只有检测到 D2D通信发现触发信号后, 才发送 D2D 通信发现信号。 实施例三 图 14为本实施例中 D2D同伴发现的信令流程示意图, 如图 14所示, 在本实施例 中, D2D同伴发现主要包括如下步骤: 步骤 S1401 ,网络设备发送配置消息。该配置消息指示 D2D通信发现信号的配置, 可以包括资源配置参数, 指示可以传输 D2D通信发现信号的子帧位置和 /或资源块位 置。 上述配置消息可以是以广播的形式发送。 例如, 上述配置消息承载于系统信息块 (SIB)中传输,可以是重用系统中原有的 SIB,或者是增加新的用于 D2D通信的 SIB。 本实施例的网络设备可以是基站, 例如 3GPP所定义的 eNB, 该 eNB包括 Relay, 或者网络中的其他低功率节点。 该网络设备也可包括其他网元, 比如 MME, 或者其 他核心网的网元。 步骤 S1402, D2D用户设备检测上述的配置消息。 如果用户设备的被发现功能开 启, 即设置为可被发现时, 该用户设备可以以图 14中所示的目标用户设备(相当于上 述的第二用户设备)的身份工作。例如,在配置消息所指示的同伴发现资源中发送 D2D 通信发现信号。 如果用户设备有同伴发现的需求,则该用户设备可以以图 14中所示的源用户设备 (相当于上述的第一用户设备) 的身份工作。 例如, 在配置消息所指示的同伴发现资 源中检测 D2D通信发现信号。 上述的 D2D通信发现信号携带有目标标识信息 (ID), 该标识可以是临时标识, 为用户设备从网络侧获得的用于 D2D通信或 D2D通信同伴发现的标识。 步骤 S1403, 源用户设备检测到 D2D通信发现信号后, 则表示在其邻近区域有其 他可被发现的用户设备;源用户设备基于检测到 D2D通信发现信号向网络请求发送该 D2D通信发现信号的目标用户设备的身份信息。 例如, 源用户设备向网络设备发送请 求消息。 该请求消息中包括有源用户设备检测到的 D2D通信发现信号中的标识信息。 步骤 S1405, 接收到源用户设备发送的同伴发现请求后, 网络设备处理该请求。 例如, 网络设备向源用户设备发送应答消息, 该应答消息中包括有目标用户设备的身 份信息, 该身份信息可以是应用层消息。 或者,网络设备可以根据预设的权限判断目标用户设备是否可被源用户设备发现。 当判断源用户设备可发现目标用户设备时, 向源用户设备发送携带有目标用户设备身 份信息的应答消息; 否则向源用户设备发送携带有拒绝信息的应答消息。 发送同伴发现请求后, 源用户设备等待接收网络设备发送的应答消息; 并根据上 述应答消息的内容确定同伴发现是否成功。 进一步的, 当检测到 D2D通信发现信号时, 如果源用户设备处于空闲 (idle, 例 如 RRC idle) 状态时, 源用户设备需要先发起连接建立请求, 与网络侧建立连接 (例 如 RRC连接), 进入连接 (connected) 状态, 再向网络侧发送同伴发现请求。 实施例四 本实施例与实施例三的区别在于, 在本实施例中, 源用户设备发起同伴发现请求 前, 先发送 D2D通信发现触发信号, 目标用户设备在接收到 D2D通信发现触发信号 后, 再发送 D2D通信发现信号。 图 15为本实施例中 D2D同伴发现的信令流程图,如图 15所示,本实施例中 D2D 同伴发现主要包括如下步骤: 步骤 S1501,网络设备发送配置消息。该配置消息指示 D2D通信发现信号的配置, 可以包括资源配置参数, 指示可以传输 D2D通信发现信号的子帧位置和 /或资源块位 置。 进一步的, 配置消息包括资源配置参数, 指示 D2D通信发现触发信号传输的子帧 位置和 /或资源块位置; 还包括 D2D通信发现触发信号配置信息, 指示可用的 D2D通 信发现触发信号集合。 或者, 配置消息包括资源配置参数, 指示 D2D通信发现信号和 /或 D2D通信发现 触发信号传输的子帧位置和 /或资源块位置; 还包括 D2D通信发现触发信号配置信息, 指示可用的 D2D通信发现触发信号集合。 上述配置消息可以是以广播的形式发送。 例如, 上述配置消息承载于系统信息块
(SIB)中传输,可以是重用系统中原有的 SIB,或者是增加新的用于 D2D通信的 SIB。 本实施例的网络设备可以是基站, 例如 3GPP所定义的 eNB, 该 eNB包括 Relay, 或者网络中的其他低功率节点。 该网络设备也可包括其他网元, 比如 MME, 或者其 他核心网的网元。 步骤 S1502, D2D用户设备检测上述的配置消息。 如果用户设备有同伴发现的需 求, 那么该用户设备可以以图 15中所示的源用户设备(即上述第一用户设备)的身份 工作。例如, 在配置消息所指示的同伴发现资源或 D2D通信发现触发信号资源中发送 D2D通信发现触发信号。 步骤 S1503, 如果用户设备的被发现功能开启, 即设置为可被发现时, 该用户设 备可以以图 15中所示的目标用户设备(即上述第二用户设备) 的身份工作。 例如, 在 配置消息所指示的同伴发现资源或 D2D通信发现触发信号资源中检测 D2D通信发现 触发信号。 如果检测到, 则在同伴发现资源中发送 D2D通信发现信号。 上述的 D2D通信发现信号携带有目标标识信息 (ID), 该标识可以是临时标识, 为用户设备从网络侧获得的用于 D2D通信或 D2D通信同伴发现的标识。 步骤 S1504, 源用户设备发送 D2D通信发现触发信号后, 等待检测 D2D通信发 现信号。如果检测到 D2D通信发现信号, 则表示在其邻近区域有其他可被发现的用户 设备; 源用户设备基于检测到 D2D通信发现信号向网络请求发送该 D2D通信发现信 号的目标用户设备的身份信息。 例如, 源用户设备向网络设备发送请求消息。 该请求 消息中包括有源用户设备检测到的 D2D通信发现信号中的标识信息。 步骤 1505, 接收到源用户设备发送的同伴发现请求后, 网络设备处理该请求。 例 如, 网络设备向源用户设备发送应答消息, 该应答消息中包括有目标用户设备的身份 信息, 该身份信息可以是应用层消息。 或者,网络设备可以根据预设的权限判断目标用户设备是否可被源用户设备发现。 当判断源用户设备可发现目标用户设备时, 向源用户设备发送携带有目标用户设备身 份信息的应答消息; 否则向源用户设备发送携带有拒绝信息的应答消息。 发送同伴发现请求后, 源用户设备等待接收网络设备发送的应答消息; 并根据上 述应答消息的内容确定同伴发现是否成功。 进一步的, 当检测到 D2D通信发现信号时, 如果源用户设备处于空闲 (idle, 例 如 RRC idle) 状态时, 源用户设备需要先发起连接建立请求, 与网络侧建立连接 (例 如 RRC连接), 进入连接 (connected) 状态, 再向网络侧发送同伴发现请求。 实施例五 本实施例中对同伴发现的资源配置方法进行说明。 用户设备发送 D2D通信发现信号的时频资源可以是预留资源。预留资源是指, 在 蜂窝通信系统中划分一部分时频资源用于 D2D通信或者用于 D2D通信时的同伴发现, UE只在该划分的资源中发送 D2DD2D通信发现信号和 /或 D2D通信发现触发信号。 例如, 按比例划分资源用于 D2D通信或者用于 D2D通信时的同伴发现。 比如, 在时 域每 n个无线帧划分 1个子帧用于 D2D通信时的同伴发现,该 1个子帧可以是约定的, 比如满足 mod ( SFN, n) =k的编号为 m的子帧, 这里 k和 m都是约定的整数, k取 值 0~n-l, m取值 0~9。 例如, n取值 4, k取 0, m取值 3, 此时 D2D同伴发现子帧 的位置如图 16中^子帧所示。 或者,用户设备发送 D2D通信发现信号的时频资源可以是网络侧通过高层信令分 配的资源。 比如, 网络侧通过广播消息如系统消息 (System Information) 向 UE广播 所分配的同伴发现资源, 也即上述预留资源方式中的 n、 k和 m等参数通过广播消息 发送, D2D用户设备通过检测广播消息获得 D2D同伴发现时频资源配置信息。 或者, 时域资源即子帧的分配也可以采用位图 (bitmap) 的方式, 例如以 1 个无线帧或者 4 个无线帧作为分配周期, 通过 i比特或者 4*i比特的位图分配同伴发现子帧资源, i为 1个无线帧中可用的子帧数, 例如使用蜂窝通信上行资源作同伴发现时, i可以是 10, 使用下行资源作同伴发现时, i可以是 6。 或者, 重用 3GPP LTE/LTE-A系统中随机接 入信道 (random access channel, 简称为 RACH) 资源的分配方法, 通过高层信令向
D2D用户设备分配专用同伴发现资源, 具体本实施例不再赘述。 频域资源的分配方法可以使用 3GPP LTE/LTE-A 中的资源分配 (resource allocation,简称为 RA)方法,例如,类型 0 (type 0),类型 1 (type 1 )或者类型 2 (type 2) 资源分配。 或者, 也可重用 RACH频域资源的分配方法, 具体本实施例不再赘述。 在本实施例中,可以使用 LTE/LTE-A系统定义的随机接入( RACH )前导( preamble ) 作为 D2D通信发现信号和 /或 D2D通信发现触发信号。 不再赘述。 从以上的描述中, 可以看出, 本发明实施例针对蜂窝通信系统中的 D2D通信, 即 D2D通信可能会与蜂窝通信共用频谱资源, 因此, 在 D2D通信的同伴发现过程中, 需要考虑潜在的 D2D通信与蜂窝通信的干扰,即需要实现 D2D通信资源的有效管理, 以及 D2D通信与蜂窝通信干扰的协调。 另一方面, 在 D2D通信的同伴发现过程中, 需要考虑同伴发现的灵活性和资源开销, 即进行同伴发现的用户设备, 应具有一定的 自主性, 并且设备发现不会产生太大的资源开销和功率浪费。 显然, 本领域的技术人员应该明白, 上述的本发明的各模块或各步骤可以用通用 的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布在多个计算装置所 组成的网络上, 可选地, 它们可以用计算装置可执行的程序代码来实现, 从而, 可以 将它们存储在存储装置中由计算装置来执行, 并且在某些情况下, 可以以不同于此处 的顺序执行所示出或描述的步骤, 或者将它们分别制作成各个集成电路模块, 或者将 它们中的多个模块或步骤制作成单个集成电路模块来实现。 这样, 本发明不限制于任 何特定的硬件和软件结合。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技 术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内, 所作的 任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
