D2D技术可以工作在授权频段或非授权频段， 允许多个支持 D2D功能 的用户设备（即 D2D用户设备， D2D User Equipment, D2D UE )在有网络 基础设施或无网络基础设施的情况下进行直接发现 /直接通信。 D2D的应用场 景主要有三种：
1 ) UE1和 UE2在蜂窝网络的覆盖下进行数据交互， 用户面数据不经过 网络基础设施， 如图 1的模式 1 ;
2 )在弱 /无覆盖区域的 UE中继传输， 如图 1中的模式 2, 允许信号质量 较差的 UE4通过附近有网络覆盖的 UE3与网络进行通信， 能帮助运营商扩 展覆盖、 提高容量；
3 )在发生地震或紧急情况，蜂窝网络不能正常工作的情况下， 允许设备 间直接通信， 如图 1中的模式 3 , UE5 , UE6和 UE7间控制面和用户面都不 经过网络基础设施而进行一跳或多跳的数据通信。 D2D技术通常包括 D2D发现技术和 D2D通信技术， 其中 , D2D发现技 术是指用于判断 /确定两个或多个 D2D用户设备之间相互邻近（例如， 在可 进行 D2D直接通信的范围之内 )或者用于判断 /确定第一用户设备邻近第二 用户设备的技术。通常， D2D用户设备间可通过发送或接收发现信号 /信息来 发现对方； D2D通信技术是指 D2D用户设备之间部分或全部通信数据可以 不通过网络基础设施而直接进行通信的技术。
根据相关 3GPP标准会议的进展，无论是 D2D发现还是 D2D通信资源， 都存在两种资源分配方式， 即基于竟争的资源获取（第一资源分配方式）或 是由基站为 UE分配专有的资源 （第二资源分配方式）进行 D2D发现 /通信。 第一资源分配方式通常由基站或是***预分配一个 D2D资源池， 参与 D2D 发现 /通信的 D2D UE监听该资源池，并通过竟争的方式获取 D2D发送资源。 而第二资源分配方式由基站根据 UE的调度请求 /緩冲区状态报告为 UE分配 合适的 D2D资源。
目前标准规定了在有蜂窝网络的覆盖场景下 D2D发现及通信资源尽可 能使用上行频谱资源。 D2D UE在使用上行频谱资源进行 D2D传输（包括 D2D发现信息以及 D2D通信数据发送） 时， D2D的传输有可能会对基站的 上行蜂窝控制信息和 /或上行蜂窝数据信息接收产生干扰。
相关技术并未对上述 D2D传输对蜂窝传输的干扰给出***完善的解决 方案。 发明内容

目前标准规定了在有蜂窝网络的覆盖场景下 D2D发现及通信资源尽可 能使用上行频谱资源。 D2D UE在使用上行频谱资源进行 D2D传输（包括 D2D发现信息以及 D2D通信数据发送） 时， D2D的传输有可能会对基站的 上行蜂窝控制信息和 /或上行蜂窝数据信息接收产生干扰。 如图 2 中 （a )所 示场景， UE1正在进行 D2D传输，而 UE3正在进行上行蜂窝通信。假设 UE1 距离基站比较近，则 UE1的 D2D传输有可能产生带内泄露（ inband emission ), 从而对 UE3 的上行控制信道（PUCCH )传输（第一干扰场景）产生干扰， 如图 2中的 （b )所示， 导致基站无法正确解出 UE3发送的上行控制信息。 除此之外， UE1的 D2D传输所产生的带内泄露还有可能会对 UE3的上行共 享信道（PUSCH )传输（第二干扰场景）产生干扰， 导致基站无法正确解出 UE3发送的上行蜂窝数据。
相关技术并未对上述 D2D传输对蜂窝传输的干扰给出***完善的解决 方案。 而本发明的实施例提出了一种设备到设备通信干扰避免方法和装置， 通过本发明的实施例提供的技术方案， 用户设备可以根据需要选择合适的资 源获取方式以及对应的发送功率， 确保 D2D传输与上行蜂窝传输的顺利进 行。
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。 下文中的 "/" 均表示 "或者" 。
本发明的实施例要解决的问题是 D2D传输产生的带内泄露对基站的上 行蜂窝控制信息和 /或上行蜂窝数据信息接收产生的干扰问题。相关技术并未 对上述 D2D传输对蜂窝传输的干扰给出***完善的解决方案。而本发明的实 施例提供了一种设备到设备通信干扰避免方法， 用户设备可以根据需要选择 合适的资源获取方式以及对应的发送功率，确保 D2D传输与上行蜂窝传输的 顺利进行。
如图 3所示，用户设备首先获取 D2D资源分配方式和 /或 D2D功控信息， 所述 D2D资源分配方式信息包括以下至少之一：
配置信息、 配置对应的资源信息、 用户设备所处场景、 所述用户设备状 态，
其中， 所述用户设备所处场景包括覆盖场景和无覆盖场景， 所述用户设 备状态包括连接态和闲置态。
所述配置信息包括以下至少之一：
第一资源分配信息、 第二资源分配信息、 第一传输节点发送的资源分配 指示信息， 所述第一传输节点包括以下一种或多种：

所述 D2D功控信息包括以下之一：
所述用户设备进行 D2D传输所允许的最大发送功率级别 /门限， 所述用户设备进行 D2D传输所允许的最小发送功率级别 /门限， 所述用户设备在所分配资源上进行 D2D传输所允许的发送功率级别 /门 限 /信噪比门限 /调整步长，
所述对应于第一资源分配信息和 /或第二资源分配信息， 及对应的 D2D 资源的用户设备 D2D传输所允许的发送功率级别 /信噪比门限，

所述对应于第一资源分配信息和 /或第二资源分配信息， 及对应的 D2D 资源对应的资源分组的用户设备 D2D传输所允许的发送功率级别 /信噪比门 限 /调整步长。
之后用户设备使用所述 D2D资源分配方式和 /或 D2D功控信息进行 D2D 传输。本发明的实施例提出的技术方案即可应用于 D2D发现也可应用于 D2D 度上緩解上行蜂窝传输对 D2D传输的干扰问题。
实施例一 本发明实施例提供了一种设备到设备通信干扰避免方法， 用户设备使用 D2D功控信息进行干扰避免。
具备 D2D通信功能的 UE1***预配置了 D2D传输所允许的最大发送功 率以及最小发送功率。此外***还有可能预配置了 D2D传输相对于基站所允 许的信噪比门限。 这些功控信息可以是***默认值， 或是内置在 UE中， 也 有可能在 UE接入网络后， 从 D2D服务器或近距离服务器或是从核心网元 MME获取 (通过 NAS消息 ) , 如图 4所示。
UE获取这些信息后， 当需要发起 D2D通信时， 首先获取 D2D资源， 在 进行 D2D传输时要保证 D2D发送功率不超过 D2D传输所允许的最大发送功 率。如果 UE获取到的功控信息包含 D2D传输相对于基站所允许的信噪比门 限， 则 UE需要监听并测量与基站之间的路损， 然后根据 D2D传输相对于基 站所允许的信噪比门限， 计算 D2D传输对应的发送功率， 保证 D2D传输时 从基站侧监听到的 D2D传输对应的信噪比不超出***配置的 D2D传输相对 于基站所允许的信噪比门限。 如果计算得出的 D2D传输发送功率大于 D2D 传输所允许的最大发送功率，则 UE使用 D2D传输所允许的最大发送功率进 行 D2D发送；如果 D2D传输发送功率小于 D2D传输所允许的最大发送功率 并且大于 D2D传输所允许的最小发送功率， 则 UE使用该 D2D传输发送功 率进行 D2D通信数据传输；如果 D2D传输发送功率小于 D2D传输所允许的 最小发送功率， 则 UE放弃 D2D传输或是向基站上报该情况。
本发明实施例提出的功控信息预配置方法可以定义***或小区级别或 UE级别的功控配置。 该方法可同时适用于连接态以及闲置态的 D2D UE的 发现 /通信。
实例二
本发明实施例提供了一种设备到设备通信干扰避免方法， 用户设备使用 D2D功控信息进行干扰避免。
具备 D2D发现功能的 UE1服务基站周期性的通过 SIB广播发送 D2D传 输所允许的最大发送功率和 /或最小发送功率和 /或 D2D传输相对于基站所允 许的信噪比门限， 如图 5所示。 广播发送的功控信息中有可能仅包含最大发 送功率信息， 也有可能仅包含信噪比门限信息。 各个小区之间可以使用完全 相同功控信息配置， 也有可能针对不同的小区以及基站的处理能力釆用变化 的功控信息。
UE1从基站接收到这些功控信息后， 当希望被其他 UE发现或是主动发 现特定的 UE时， 首先获取 D2D资源， 在进行 D2D传输时要保证 D2D发送 功率不超过 D2D传输所允许的最大发送功率。如果 UE获取到的功控信息包 含 D2D传输相对于基站所允许的信噪比门限，则 UE需要监听并测量与基站 之间的路损，然后根据 D2D传输相对于基站所允许的信噪比门限，计算 D2D 传输对应的发送功率， 保证 D2D传输时从基站侧监听到的 D2D传输对应的 信噪比不超出 SIB广播发送的 D2D传输相对于基站所允许的信噪比门限。如 果计算得出的 D2D传输发送功率大于 D2D传输所允许的最大发送功率， 则 UE使用 D2D传输所允许的最大发送功率进行 D2D发送； 如果 D2D传输发 送功率小于 D2D传输所允许的最大发送功率并且大于 D2D传输所允许的最 小发送功率， 则 UE使用该 D2D传输发送功率进行 D2D通信数据传输； 如 果 D2D传输发送功率小于 D2D传输所允许的最小发送功率，则 UE放弃 D2D 传输或是向基站上报该情况。
本发明实施例提出的功控信息发送方法可以定义***或小区级别的功控 配置。 该方法可同时适用于连接态以及闲置态的 D2D UE的发现 /通信。 考虑 到 D2D UE的移动， 通过 SIB广播发送的功控信息可在 D2D UE切换准备阶 段从目标基站发送给源基站。
实例三
本发明实施例提供了一种设备到设备通信干扰避免方法， 用户设备使用 D2D功控信息进行干扰避免。
具备 D2D通信功能的 UE1可从服务基站接收通过专有信令发送的 D2D 传输所允许的最大发送功率和 /或最小发送功率和 /或 D2D传输相对于基站所 允许的信噪比门限,如图 6所示。基站所发送的专有信息有可能是 RRC信令， 复用相关的 RRC连接建立或是 RRC连接重配消息，或是设计新的 RRC消息 携带所述 D2D功控信息。通过专有信令发送的功控信息中有可能仅包含最大 发送功率信息， 也有可能仅包含信噪比门限信息。 基站所服务的各个 UE可 以使用完全相同功控信息配置， 也有可能针对不同的 UE釆用变化的功控信 息。
UE1从基站接收到这些功控信息后， 当希望进行 D2D通信时， 首先获 取 D2D资源， 在进行 D2D传输时要保证 D2D发送功率不超过 D2D传输所 允许的最大发送功率。如果 UE获取到的功控信息包含 D2D传输相对于基站 所允许的信噪比门限， 则 UE需要监听并测量与基站之间的路损， 然后根据 D2D传输相对于基站所允许的信噪比门限， 计算 D2D传输对应的发送功率， 保证 D2D传输时从基站侧监听到的 D2D传输对应的信噪比不超出通过专有 信令获取到的 D2D传输相对于基站所允许的信噪比门限。 如果计算得出的 D2D传输发送功率大于 D2D传输所允许的最大发送功率， 则 UE使用 D2D 传输所允许的最大发送功率进行 D2D发送；如果 D2D传输发送功率小于 D2D 传输所允许的最大发送功率并且大于 D2D传输所允许的最小发送功率， 则 UE使用该 D2D传输发送功率进行 D2D通信数据传输； 如果 D2D传输发送 功率小于 D2D传输所允许的最小发送功率， 则 UE放弃 D2D传输或是向基 站上报该情况。
除了 UE在初始接入时获取 D2D功控信息， D2D功控信息也有可能在基 站为 UE分配专有 D2D资源时发送。 如 D2D UE1使用第二资源分配方式获 取 D2D资源，则 UE1发送调度请求 /緩冲区状态报告 (buffer status report, BSR) 给基站， 基站收到该消息后， 为 UE1分配资源并为 UE确定在所分配资源上 进行 D2D传输所允许的发送功率或信噪比门限。 之后基站可通过 RRC信令 或信噪比门限发送给 UE1。
UE1从基站接收到资源分配及功控信息后， 使用基站发送的 D2D传输 所允许的发送功率或是根据基站发送的 D2D传输所允许的信噪比门限计算 如果基站检测到蜂窝上行控制信道和 /或蜂窝上行共享信道被干扰，则基 站判断被干扰的蜂窝上行控制信道和 /或蜂窝上行共享信道资源是否与 D2D 通信数据资源邻近。 如果邻近， 则基站监听 D2D通信控制资源， 解析用户设 备发送的调度分配信息，确定使用与被干扰的蜂窝上行控制信道和 /或蜂窝上 行共享信道资源邻近的 D2D通信数据资源的用户设备， 假设产生干扰的 UE 为 UE1 , 则基站组装包含当前 D2D传输所允许的发送功率或信噪比门限信 息的消息， 并通过专有信令发送给 UE1。
本发明实施例提出的功控信息发送方法可以定义***或小区级别或 UE 级别的功控配置。 该方法可仅适用于连接态的 D2D UE的发现 /通信。 考虑到 D2D UE的移动， 通过专有信令发送的功控信息可在 D2D UE切换准备阶段 从目标基站发送给源基站， 并由源基站发送给 UE。

( hysical resource block , PRB )为一组， 剩余 PRB为一组， 或者， 特定时 域位置边带为一组， 特定时域位置剩余 PRB为一组， 剩余时域位置为一组， 或者， 特定时域位置为一组， 剩余时域位置为一组， 或者， 根据传输次数分 组， 如： 首传一组， 重传一组， 或， 第一次传输为一组， 第二传输为一组， 第三次传输为一组等。这种对发送功率级别 /信噪比门限进行分组以及对应的 编码的方式也适用于前面的实例 1-3。 基站可以设计新的 SIB或是复用相关 的 SIB增加新的与前述功控相关的字段。
UE1从基站接收到这些功控信息后， 当希望进行 D2D通信时， 首先获 取 D2D资源，然后根据相应的 D2D资源池对应的用户设备 D2D传输所允许 的发送功率，或对应于获取到的资源单元对应的用户设备 D2D传输所允许的 发送功率确定 D2D传输的发送功率。如果 UE获取到的功控信息包含对应于 D2D资源池或是 D2D资源池的每个资源分配单元对应的 D2D传输相对于基 站所允许的信噪比门限， 则 UE需要监听并测量与基站之间的路损， 然后根 据 UE获取资源的 D2D资源池和 /或获取到的资源对应的 D2D传输相对于基 站所允许的信噪比门限， 计算 D2D传输对应的发送功率， 保证 D2D传输时 从基站侧监听到的 D2D传输对应的信噪比不超出 SIB广播发送的 D2D传输 相对于基站所允许的信噪比门限。如果 UE获取的功控信息还包括 D2D传输 所允许的最大发送功率以及 D2D传输所允许的最大发送功率信息， UE判断 如果计算得出的 D2D传输发送功率大于 D2D传输所允许的最大发送功率， 则 UE使用 D2D传输所允许的最大发送功率进行 D2D发送； 如果 D2D传输 发送功率小于 D2D传输所允许的最大发送功率并且大于 D2D传输所允许的 最小发送功率， 则 UE使用该 D2D传输发送功率进行 D2D通信数据传输； 如果 D2D传输发送功率小于 D2D传输所允许的最小发送功率， 则 UE放弃 D2D传输或是向基站上报该情况。
本发明实施例提出的功控信息发送方法可以定义***或小区级别的功控 配置。 该方法可仅适用于连接态以及空闲态的 D2D UE的发现 /通信。 考虑到 D2D UE的移动， 通过专有信令发送的功控信息可在 D2D UE切换准备阶段 从目标基站发送给源基站， 并由源基站发送给 UE。 实例五
本发明实施例提供了一种设备到设备通信干扰避免方法， 用户设备使用
D2D功控信息进行干扰避免。
具备 D2D通信功能的 UE1可从服务基站接收通过专有信令发送的对应 于第一和 /或第二资源分配方式 D2D资源池的用户设备 D2D传输所允许的发 送功率级别 /信噪比门限， 或对应于第一和 /或第二资源分配方式 D2D资源池 包含的每个资源分配单元的用户设备 D2D传输所允许的发送功率级别 /信噪 比门限， 如图 8所示。 对应于第一和 /或第二资源分配方式 D2D资源池的用 户设备 D2D传输所允许的发送功率级别 /信噪比门限可以是一个列表， 列表 中的每个元素是针对某个 D2D资源池的用户设备 D2D传输所允许的最大发 送功率级别 /信噪比门限。 而对应于第一和 /或第二资源分配方式 D2D资源池 包含的每个资源分配单元的用户设备 D2D传输所允许的发送功率级别 /信噪 比门限则是针对每个 D2D 资源池都有一个列表， 列表中的每个元素是针对 D2D资源池包含的每个资源分配 /竟争单元的用户设备 D2D传输所允许的最 大发送功率级别 /信噪比门限。 用户设备 D2D传输所允许的最大发送功率级 别 /信噪比门限可以通过一个 bit来指示， 如 0标识高， 1标识低， 分别对应 ***预定义的发送功率级别 /信噪比门限值，这种情况下，列表成为了 bitmap。 除此之外， 用户设备 D2D传输所允许的最大发送功率级别 /信噪比门限也可 以通过预先定义的若干发送功率级别 /信噪比门限级别来指示，不同的级别通 过编码后的信息指示。 除此之外， 还可将所述 D2D资源池按照频域和 /或时 域位置分组， 不同组分别进行功率控制， 此时列表中的每个元素指示某个组 的发送功率级别 /信噪比门限； 如： 两个边带为一组， 中心为一组， 或者， 特 定 PRB为一组， 剩余 PRB为一组， 或者， 特定时域位置边带为一组， 特定 时域位置剩余 PRB为一组， 剩余时域位置为一组， 或者， 特定时域位置为一 组， 剩余时域位置为一组， 或者， 根据传输次数分组， 如： 首传一组， 重传 一组， 或， 第一次传输为一组， 第二传输为一组， 第三次传输为一组等。
基站所发送的专有信息有可能是 RRC信令， 复用相关的 RRC连接建立 或是 RRC连接重配消息， 或是设计新的 RRC消息携带所述 D2D功控信息。 通过专有信令发送的功控信息中有可能仅包含所允许的最大发送功率信息， 也有可能仅包含信噪比门限信息。 基站所服务的各个 UE可以使用完全相同 功控信息配置， 也有可能针对不同的 UE釆用变化的功控信息。
UE1从基站接收到这些功控信息后， 当希望进行 D2D通信时， 首先获 取 D2D资源，然后根据相应的 D2D资源池对应的用户设备 D2D传输所允许 的发送功率，或对应于获取到的资源单元对应的用户设备 D2D传输所允许的 发送功率确定 D2D传输的发送功率。如果 UE获取到的功控信息包含对应于 D2D资源池或是 D2D资源池的每个资源分配单元对应的 D2D传输相对于基 站所允许的信噪比门限， 则 UE需要监听并测量与基站之间的路损， 然后根 据 UE获取资源的 D2D资源池和 /或获取到的资源对应的 D2D传输相对于基 站所允许的信噪比门限， 计算 D2D传输对应的发送功率， 保证 D2D传输时 从基站侧监听到的 D2D 传输对应的信噪比不超出通过专有信令接收到的 D2D传输相对于基站所允许的信噪比门限。 如果 UE获取的功控信息还包括 D2D传输所允许的最大发送功率以及 D2D传输所允许的最大发送功率信息， UE判断如果计算得出的 D2D传输发送功率大于 D2D传输所允许的最大发送 功率，则 UE使用 D2D传输所允许的最大发送功率进行 D2D发送；如果 D2D 传输发送功率小于 D2D传输所允许的最大发送功率并且大于 D2D传输所允 许的最小发送功率， 则 UE使用该 D2D传输发送功率进行 D2D通信数据传 输； 如果 D2D传输发送功率小于 D2D传输所允许的最小发送功率， 则 UE 放弃 D2D传输或是向基站上报该情况。
除此之外， 当 UE1接收到所述 D2D功控信息后， 还可以根据上述 D2D 功控信息选择合适的 D2D资源。 如 UE1获取到对应于第一和 /或第二资源分 配方式 D2D资源池的用户设备 D2D传输所允许的发送功率级别 /信噪比门限 信息， 则 UE1 可选择所允许的用户设备发送功率级别 /信噪比门限在用户设 备进行 D2D传输所允许的最大发送功率级别 /门限以及最小发送功率级别 /门 限范围内的 D2D资源池以及对应的资源分配方式， 然后根据确定的 D2D资 源分配方式进行 D2D资源获取。 如果 UE1获取到对应于第一和 /或第二资源 分配方式 D2D资源池包含的每个资源分配单元的用户设备 D2D传输所允许 的发送功率级别 /信噪比门限信息， 则 UE1可根据 D2D资源池包含的每个资 源分配单元的用户设备 D2D传输所允许的发送功率级别 /信噪比门限， 确定 用户设备可接受的 D2D资源池包含的资源子集， 然后根据确定的 D2D资源 池子集进行 D2D资源获取。
本发明实施例提出的功控信息发送方法可以定义***或小区级别或 UE 级别的功控配置。 该方法仅适用于连接态的 D2D UE 的发现 /通信。 考虑到 D2D UE的移动， 通过专有信令发送的功控信息可在 D2D UE切换准备阶段 从目标基站发送给源基站， 并由源基站发送给 UE。
实施例六
本发明实施例提供了一种设备到设备通信干扰避免方法， 用户设备使用
D2D资源分配方式信息进行干扰避免。
具备 D2D发现功能的 UE1可从服务基站接收通过专有信令发送的各个 D2D资源池对应的资源分配方式， 和 /或允许 /禁止所述用户设备使用第一 /第 二资源分配方式获取 D2D资源的信息，如图 9所示。基站所发送的专有信息 有可能是 RRC信令，复用相关的 RRC连接建立或是 RRC连接重配消息，或 是设计新的 RRC消息携带所述 D2D功控信息。如果针对 D2D发现资源，基 站同时允许用户设备使用一个以上 D2D资源池和 /或一种以上 D2D资源分配 方式，则基站通过专有信令发送的资源分配信息还可以包括不同 D2D资源池 和 /或不同资源分配方式对应的优先级和 /或适用场景 /地理范围信息， 如有覆 盖场景下第二资源分配方式优先级高于第二资源分配方式， 或连接态用户设 备优选第二资源分配方式对应的资源池而闲置态用户设备优选专用于闲置态 用户的第一资源分配方式资源池。 基站所服务的各个 UE可以使用完全相同 资源分配方式， 也有可能针对不同的 UE釆用变化的资源分配方式。
UE1从基站接收到这些资源分配方式信息后， 当希望被其他 UE发现或 是主动发现其他 UE时， UE1根据获取到的资源分配方式获取资源。 如果允 许第一资源分配方式， 则从第一资源分配方式对应的 D2D资源池获取资源， 如果允许第二资源分配方式， 则向基站发送调度请求或緩冲区状态报告请求 分配 D2D资源， 如果同时允许第一和第二资源分配方式， 则根据优先级和 / 或适用场景信息确定资源分配方式。 资源分配方式确定后， 如果是第一资源 分配方式， 则用户设备监听第一资源分配方式对应的 D2D资源池。 优选的， 如果第一资源分配方式对应的 D2D资源池有多个， 则 UE1根据资源池优先 级 /或适用场景信息确定特定的 D2D资源池。 UE1还可以根据实例 1~5方式 获取到的 UE功控信息确定 D2D资源子集， 如 UE1根据 D2D资源池包含的 每个资源分配单元的用户设备 D2D传输所允许的发送功率级别 /信噪比门限， 确定 UE1可接受的 D2D资源池包含的资源子集， 然后根据确定的 D2D资源 池子集， 通过竟争的方式获取 D2D发送资源。
如果是第二资源分配方式，则用户设备发送调度请求 /緩冲区状态报告给 基站， 由基站为 UE分配合适的 D2D资源。 如果基站为 UE1分配的 D2D资 源时没有包含 D2D功控信息， 而 UE1之前获取到了 D2D功控信息， 则 UE1 根据实例 1 ~5提到的发送功率计算方法计算 D2D发送功率，在所分配资源上 使用该 D2D发送功率进行 D2D通信。如果 UE1在所分配资源上计算得到的 D2D传输发送功率小于 D2D传输所允许的最小发送功率， 则 UE放弃 D2D 传输或是向基站上报该情况。
本发明实施例提出的资源分配方式信息发送方法可以定义***或小区级 别或 UE级别的资源分配方式配置。 该方法仅适用于连接态的 D2D UE的发 现 /通信。考虑到 D2D UE的移动，通过专有信令发送的功控信息可在 D2D UE 切换准备阶段从目标基站发送给源基站， 并由源基站发送给 UE。
实例七
本发明实施例提供了一种设备到设备通信干扰避免方法， 用户设备使用 D2D资源分配方式信息进行干扰避免。
具备 D2D通信功能的 UE1预先获取了 D2D传输所允许的资源分配方式。 优选的资源分配方式信息包括： 各个 D2D资源池对应的资源分配方式， 和 / 允许 /禁止所述用户设备使用第一 /第二资源分配方式获取 D2D资源的信息。 如果针对 D2D发现资源， 基站同时允许用户设备使用一个以上 D2D资源池 和 /或一种以上 D2D资源分配方式， 则基站通过专有信令发送的资源分配信 息还可以包括不同 D2D资源池和 /或不同资源分配方式对应的优先级和 /或适 用场景 /地理范围信息。 这些资源分配方式信息可以是***默认值， 或是内置 在 UE中， 也有可能在 UE接入网络后， 从 D2D服务器或近距离服务器或是 从核心网元 MME获取 (通过 NAS消息） ， 如图 10所示。 ***可以使用完 全相同上述资源分配方式信息配置， 也有可能针对不同的 UE而釆用变化的 资源分配方式信息配置。
UE获取这些信息后， 当需要发起 D2D通信时， 首先判断资源分配方式 信息，如果允许第一资源分配方式，则从第一资源分配方式对应的 D2D资源 池获取资源， 如果允许第二资源分配方式， 则向基站发送调度请求或緩冲区 状态报告请求分配 D2D资源，如果同时允许第一和第二资源分配方式，则根 据优先级和 /或适用场景信息确定资源分配方式。 资源分配方式确定后， 如果 是第一资源分配方式， 则用户设备监听第一资源分配方式对应的 D2D 资源 池。 优选的， 如果第一资源分配方式对应的 D2D资源池有多个， 则 UE1才艮 据资源池优先级和 /或适用场景信息确定特定的 D2D资源池和 /或 D2D资源子 集， 最后通过竟争的方式获取 D2D发送资源。
如果是第二资源分配方式，则用户设备发送调度请求 /緩冲区状态报告给 基站， 由基站为 UE分配合适的 D2D资源。 如果基站为 UE1分配的 D2D资 源时没有包含 D2D功控信息， 而 UE1之前获取到了 D2D功控信息， 则 UE1 根据实例 1 ~5提到的发送功率计算方法计算 D2D发送功率，在所分配资源上 使用该 D2D发送功率进行 D2D通信。如果 UE1在所分配资源上计算得到的 D2D传输发送功率小于 D2D传输所允许的最小发送功率， 则 UE放弃 D2D 传输或是向基站上报该情况。
本发明实施例提出的功控信息预配置方法可以定义***或小区级别或 UE级别的功控配置。 该方法可同时适用于连接态以及闲置态的 D2D UE的 发现 /通信。
实例八
本发明实施例提供了一种设备到设备通信干扰避免方法， 用户设备使用 D2D资源分配方式信息进行干扰避免。
具备 D2D通信功能的 UE1发起 D2D通信，首先选择使用第一资源分配 方式获取资源进行 D2D传输。 在此期间， 基站检测到蜂窝上行控制信道和 / 或蜂窝上行共享信道被干扰或基站收到来自用户设备的干扰以及功控问题上 报，则基站通过专有信令向 UE1发送禁止使用第一资源分配方式对应的 D2D 资源指示， 如图 11所示。 该指示可通过 RRC信令/ MAC CE/PDCCH发送给 UE1。 UE1接收到该指示后， 停止使用第一资源分配方式获得的 D2D资源， 在此期间， UE1允许使用第二资源分配方式获取资源， 则 UE1可以使用第二 资源分配方式获取 D2D资源进行 D2D传输。 过一段时间后， 如果基站检测 到干扰情况好转， 或是 UE1移动到了不会出现干扰或功控问题的区域， 则基 站可通过专有信令向 UE1发送允许使用第一资源分配方式对应的 D2D资源 指示。 该指示可通过 RRC信令/ MAC CE/PDCCH发送给 UE1。 UE1接收到 该指示后， 可选择重新使用第一资源分配方式获得的 D2D资源。
实例九
本发明实施例提供了一种设备到设备通信干扰避免方法， 基站通过广播 信令或是通过专有信令向 UE发送 D2D资源分配方式和 /或 D2D功控信息之 前， 基站可基站启动时预配置 D2D资源分配方式和 /或 D2D功控信息， 之后 通过***广播信令或是在 UE接入时下发该信息。 如果***配置发生变化， 则基站可通过***消息更新流程或专有信令下发更新后的 D2D 资源分配方 式和 /或 D2D功控信息。
除此之外，基站还有可能在 S1连接建立时从 MME获取针对整个***或 小区级别的 D2D资源分配方式和 /或 D2D功控信息， 则基站通过***广播信 令或是专有信令发送给具备 D2D能力（根据核心网 HSS签约信息， MME鉴 权之后的 D2D发现 /通信能力） 的 UE。 或是在 UE接入时从 MME获取针对 特定 UE的经过鉴权的 D2D资源分配方式和 /或 D2D功控信息，如图 12所示 , 之后基站通过专有信令发送给该 UE。
