实施例一
图 1 为本发明实施例一提供的无线通信方法的流程图, 参见图 1, 本实 施例的方法具体包括:
步骤 101 : 基站向用户设备 UE发送侦听配置信息;

可选地, 在步骤 101之前, 本实施例的方法还包括: 基站生成侦听配置 信息。
步骤 102 : UE根据所述侦听配置信息, 对待侦听频谱进行干扰侦听, 得 到第一侦听结果;
在实际应用中, 所述待侦听频谱可以为未授权频谱, 也可以为授权频谱, 在本实施例中, 所述待侦听频谱优选为未授权 (unlicensed ) 频谱。
可选地, 所述侦听配置信息中可以包括待侦听频谱的描述信息, 该步 骤中, UE具体根据侦听配置信息中的待侦听频谱的描述信息, 对所述待侦 听频谱进行干扰侦听, 其中, 所述待侦听频谱的描述信息包括待侦听频谱 的时域信息和 /或频域信息。 时域信息可以表示为针对待侦听频谱上的一 个或多个载波上, 进行侦听的时间集合信息比如子帧集合信息, 时域信息 可以采用配置异频测量间隔 (Measurement gap ) 的方式来实现, 也可以 采用其他方式来实现, 在此不做限定。 需要说明的是, 如果基站没有在待 侦听频谱上发送信号, 那么 UE对于待侦听频谱上时间的理解, 可以为 UE 在当前使用的频谱上的时间理解, 例如可以根据当前使用的频谱子帧信 息, 确定待侦听频谱的第 n个子帧。 待侦听频谱的描述信息可以预置在基 站中, 也可以由基站临时确定, 优选地, 在本实施例中, 为减轻 UE的负 担, 精确缩减 UE待侦听的频谱, 可以先由基站预先对可用频谱进行侦听, 根据侦听结果, 基站过滤出较为空闲的频谱并确定频谱的描述信息, 从而 得到所述待侦听频谱的描述信息, 所述可用频谱为包含待侦听频谱的未授 权频谱, 具体可以为所有的未授权频谱, 相应地, 步骤 101之前, 所述基 站还执行以下步骤:
对可用频谱上进行干扰侦听, 得到第二侦听结果, 所述可用频谱为包 含所述待侦听频谱的未授权频谱。
或者, 基站将侦听得到的第二侦听结果携带在所述侦听配置信息中发 送给 UE , 步骤 102中 UE根据所述侦听配置信息, 对待侦听频谱进行干扰 侦听, 包括: UE根据第二侦听结果, 确定出较为空闲的空闲频谱并确定空 闲频谱的描述信息, 从而得到待侦听频谱的描述信息, 根据确定出的待侦 听频谱的描述信息对待侦听频谱进行干扰侦听。
或者, 所述待侦听频谱的描述信息预置在 UE侧, UE根据自身预置的 待侦听频谱的描述信息进行干扰侦听。
上述第二侦听结果具体可以为可用频谱上的信号的能量信息。
可选地, 为控制 UE的干扰侦听, 基站可以在步骤 102之前, 通过向 UE发送触发指令来开启或结束 UE的干扰侦听。
可选地, 为控制 UE的干扰侦听, 基站也可以通过在所述侦听配置信 息中携带侦听时间信息或侦听触发条件信息来控制 UE的干扰侦听。 所述 侦听时间信息, 用于指示所述 UE开始和 /或停止对所述待侦听频谱进行干 扰侦听的时间; 或者用于指示所述 UE以所述侦听时间信息为周期, 对所 述待侦听频谱进行干扰侦听, 所述侦听触发条件用于指示所述 UE在当前 使用的信道的质量满足所述触发条件时, 对所述待侦听频谱进行干扰侦 听, 相应地, 步骤 102中 UE根据所述侦听配置信息, 对待侦听频谱进行 干扰侦听具体还包括: 根据侦听配置信息中的侦听时间信息或侦听触发条 件信息, 对待侦听频谱进行干扰侦听。 其中, 所述 UE在当前使用的信道 的质量可以根据当前使用的信道的参考信号接收功率 RSRP ( Reference signal received power ) 、 参考信号接收质量 RSRQ ( Reference signal received qual ity ) 、 信道质量指示 CQI ( Channel qual ity indicator ) 、 参考信号强度指示 RSSI ( Received Signal Strength Indicator ) 中的至 少一项来确定。
另外,也可以通过将所述侦听时间信息或侦听触发条件信息预置在 UE 中, 从而使得 UE可以根据预置的侦听时间信息或侦听触发条件来控制自 身对待侦听频谱的干扰侦听。
步骤 103: UE将第一侦听结果发送给所述基站;
在本实施例中, 所述侦听配置信息中还可以包括指示所述 UE上报所 述第一侦听结果时所占用资源的上报配置信息, 或者, 所述上报配置信息 预先设定并预置在 UE 中, 所述上报配置信息包括时域信息、 频域信息和 码域信息中的至少一个, 相应地, 步骤 103中 UE将第一侦听结果发送给所 述基站, 包括:
UE在所述上报配置信息对应的资源上将第一侦听结果发送给所述基站。 步骤 104: 基站根据第一侦听结果, 从待侦听频谱中选择空闲频谱; 所述 UE上报的第一侦听结果,可以为待侦听频谱上的干扰信号的能量信 息, 也可以为 UE选择的空闲频谱的描述信息。
由于当基站在待侦听频谱上为其他 UE提供数据服务时, UE对待侦听频 谱上的信号侦听得到的能量信息, 包括干扰信号的能量信息及当前基站发 送的信号的能量信息 S,其中所述干扰信号为当前基站之外的其他设备(可 以为其他基站、 wifi设备等)在待侦听频谱上发送的信号, 干扰信号的能 量信息可以用干扰信号的能量 I ( interference ) 表示, 也可以用 I和噪 声 N ( noise )表示, 干扰信号的能量信息的值可以等于干扰信号的能量 I, 也可以等于 I与噪声 N之和, 具体地, 在本实施例中以所述干扰信号的能 量信息的值为 I+N为例。 基站所发送的信号会影响所述 UE对干扰信号的侦 听结果, 若不考虑基站发送的信号的影响或基站未在待侦听频谱上发送信 号时, 所述侦听频谱上的干扰信号的能量信息可以通过 UE 对待侦听频谱上 的所有的信号进行能量检测得到。 若需要排除基站自身所发送的信号对第一 侦听结果的影响, 进一步提高干扰侦听的精准度, 本实施例的中, 步骤 102 之前还包括:
基站向所述 UE发送当前基站对所述待侦听频谱的使用状态信息,所述 使用状态信息包括当前基站在所述待侦听频谱上发送的信号对应的数据 调度信息。
具体地,基站发送的待侦听频谱的使用状态信息中不携带用户设备 ID ( User equipment identificat ion? UE ID ) , 从而使得任何一个 UE者 β 可以通过解析得到待侦听频谱的使用状态信息, 获知待侦听频谱上的数据 调度情况, 所述基站发送的待侦听频谱的使用状态信息, 具体可以承载在 物理下行控制信道 PDCCH ( Physical downl ink control channel ) 中, 也 可以是承载在增强下行控制信道 EPDCCH ( Enhanced physical downl ink control channel ) 中。
相应地, 若所述第一侦听结果为待侦听频谱上的干扰信号的能量信息, 步骤 102 中 UE根据所述侦听配置信息, 对待侦听频谱进行干扰侦听, 得到 第一侦听结果具体还包括:
所述 UE对待侦听频谱上的信号进行侦听, 得到待侦听频谱上的信号 的能量信息, 根据所述当前基站对所述待侦听频谱的使用状态信息, 确定 所述基站发送的信号的能量信息;
所述 UE根据待侦听频谱上的信号的能量信息及所述基站发送的信号 的能量信息, 确定待侦听频谱上的干扰信号的能量信息, 得到所述第一侦 听结果。
上述实施例中, 当所述基站在待侦听频谱上为其他 UE发送信号时, 根据基站发送的当前基站对所述待侦听频谱的使用状态信息, 所述 UE可 以恢复基站发送的信号的能量信息 S , 进而精确得到干扰信号的能量 I和 噪声 N, 提高了 UE对待侦听频谱进行干扰侦听的精准度。
当所述第一侦听结果为待侦听频谱上的干扰信号的能量信息时, 相应 地, 步骤 104中基站根据第一侦听结果, 从待侦听频谱中选择空闲频谱, 具体包括:
基站根据所述待侦听频谱上的干扰信号的能量信息, 从所述待侦听频 谱中选择满足预设条件的待侦听频谱。
本实施例中, 所述预设条件可以根据需要设定, 将满足预设条件的待 侦听频谱确定为空闲频谱。 由于干扰信号的能量信息的值越小, 对应的频 谱越空闲, 待侦听频谱的信干噪比 SINR ( Signal interference noise ratio) 及待侦听频谱的信道质量指示 CQI 越大代表该频谱对应的信道质 量越好, 频谱越空闲, 因此, 本实施例中, 所述预设条件具体可以包括以 下三项中的至少一项:
待侦听频谱上的干扰信号的能量信息的值小于第一预设值;
待侦听频谱的信干噪比 SINR的值大于第二预设值, 所述 SINR的值为 所述 UE在当前使用的信道的参考信号接收功率 RSRP与该待侦听频谱上的 干扰信号的能量信息的值的比值, 即 RSRP/ (N+I), 或所述 SINR的值为所 述 UE在当前使用的信道的接收信号能量与该待侦听频谱上的干扰信号的 能量信息的值比值;
待侦听频谱的信道质量指示 CQI大于第三预设值, 所述 CQI的值对应 于所述 UE在当前使用的信道的 RSRP与该待侦听频谱上的干扰信号的能量 信息的值的比值, 或者, 所述 CQI的值对应于所述 UE在当前使用的信道 的接收信号能量与该待侦听频谱上的干扰信号的能量信息的值的比值。
本实施例中, 所述 UE在当前使用的信道的参考信号接收功率 RSRP与 待侦听频谱上的干扰信号的能量信息的值的比值, 与所述 CQI存在对应关 系, 这里的对应关系可以表示为: 如果所述 UE在当前使用的信道的参考 信号接收功率 RSRP与待侦听频谱上的干扰信号的能量信息的值的比值越 大, 即 RSRP/ (I+N)的值越大, 则 CQI越大。 所述 UE在当前使用的信道的 接收信号能量的值与待侦听频谱上的干扰信号的能量信息的值的比值, 与 所述 CQI也存在对应关系, 所述 UE在当前使用的信道的接收信号能量与 待侦听频谱上的干扰信号的能量信息的值的比值越大,则 CQI越大。因此, 根据所述 UE在当前使用的信道的参考信号接收功率 RSRP与待侦听频谱上 的干扰信号的能量信息的值的比值, 或者根据所述 UE在当前使用的信道 的接收信号能量与待侦听频谱上的干扰信号的能量信息的值的比值, 可以 确定对应的 CQI的值。
其中, 所述 UE在当前使用的信道的 RSRP、 UE在当前使用的信道的接 收信号能量, 具体可以由 UE上报给基站, 另外, 基站也可以根据 UE上报 的在当前使用的信道的 RSRQ和 RSSI ,计算出 UE在当前使用的信道的 RSRP 或 UE在当前使用的信道的接收信号能量。所述 UE当前使用的信道具体可 以为 UE当前使用或激活的频谱对应的信道, 例如可以为该 UE的主小区 (Primary cel l : Pcel l ) 的频谱对应的信道, 也可以是已经被激活的 UE 的辅小区 (Secondary cel l ; Scel l ) 的频谱对应的信道。
可选地, 在上述实施例中, 若所述第一侦听结果为 UE选择的空闲频 谱的描述信息, 即空闲频谱是由 UE来选择时, 相应地, 步骤 102中 UE根 据所述侦听配置信息, 对待侦听频谱进行干扰侦听, 得到第一侦听结果, 具体包括: 所述 UE对待侦听频谱进行干扰侦听得到待侦听频谱上的干扰 信号的能量信息; 根据所述待侦听频谱上的干扰信号的能量信息, 从所述 待侦听频谱中选择满足上述预设条件的频谱作为空闲频谱, 确定所述空闲 频谱的描述信息, 得到所述第一侦听结果。 相应地, 步骤 104中基站根据 第一侦听结果, 从待侦听频谱中选择空闲频谱, 具体包括: 基站根据 UE 上报的空闲频谱的描述信息, 从待侦听频谱中选择出所述空闲频谱。
步骤 105: 基站在所述空闲频谱上与 UE进行通信。
优选地, 在本实施例中, 通过所述空闲频谱的 SINR或 CQI , 可以辅助 基站在选择的空闲频谱上进行数据调度, 具体的, 基站可以通过所述空闲 频谱的 SINR或者 CQI , 确定和所述 UE在选择的空闲频谱上进行数据通信 所对应的调制编码方案 MCS (Modulator Coder Scheme ), 并根据所述 MCS, 对所述 UE数据通信数据进行编码调制。
在步骤 105之后, 基站可以将选择的空闲频谱配置为该 UE的辅小区 Scel l对应的频谱。
可选地, 当基站接收到多个 UE上报的第一侦听结果, 且为多个 UE选 择的空闲频谱为同一频谱资源时, 为保证 UE与基站的通信质量, 基站优 先将选择的空闲频谱配置给最适合的 UE, 只将最合适的 UE调度在该空闲 频谱上, 其中, 最适合的 UE是指: 该 UE进行干扰侦听得到的干扰信号的 能量信息的值最小, 或者该 UE在干扰侦听频谱上对应的 SINR的值最大, 又或者, 该 UE在干扰侦听频谱上对应的 CQI的值最大。
由于处于基站及基站的隐藏节点的共同覆盖范围内的 UE可以侦听到隐藏 节点发送的干扰信号, 因此本实施例的方法中, 通过 UE对待侦听频谱进行侦 听, 可以扩大基站干扰侦听范围, 发现对于基站而言的隐藏节点, 从而使得 基站可以选择合适的非授权频谱和 UE进行通信, 降低了基站和 UE之间在选 择的非授权频谱上进行通信可能受到的干扰强度。
本实施例的方法可以降低基站的隐藏节点对基站与 UE 之间的通信的影 口向, 根据本实施例的方法, 本领域技术人员容易想到将本实施例中的基站替 换为其他接入点设备, 可以实现降低接入点设备的隐藏节点对该接入点设备 与 UE之间的通信的影响。

可选地, 所述 UE中也可以预置有待侦听频谱的描述信息, 所述待侦听频 谱的描述信息包括待侦听频谱的时域信息和 /或频域信息, 其中, 时域信息 可以表示为针对待侦听的未授权频谱上的一个或多个载波上, 进行侦听的 时间信息例如子帧信息, 所述第一侦听结果为 UE根据预置的待侦听频谱 的描述信息进行干扰侦听得到。

可选地, 为提高 UE侦听的灵活性, UE可以根据基站生成的侦听配置 来进行侦听, 相应地, 步骤 201之前还包括:
生成侦听配置信息,所述侦听配置信息用于配置用户设备 UE进行干扰侦 听,所述干扰侦听是指对待侦听频谱进行能量检测,所述待侦听频谱属于未授 权频谱;
向所述 UE发送侦听配置信息, 以使所述 UE根据所述侦听配置信息对待 侦听频谱进行干扰侦听。
具体地, 基站通过无线资源控制 RRC专有信令、 RRC广播信令、 媒体接 入控制 MAC信令或物理层信令向所述 UE发送侦听配置信息。
可选地, 上述的指示所述 UE 上报所述第一侦听结果时所占用资源的 上报配置信息、 待侦听频谱的描述信息、 侦听时间信息、 侦听触发条件信 息中的一项或多项也可以携带在所述侦听配置信息中, 由基站发送给 UE。
可选地, 在本实施例中, 为降低 UE的负担, 缩减 UE需要侦听的频谱, 可以先由基站对可用频谱预先进行侦听, 并根据侦听结果过滤出基站认为 空闲的频谱作为 UE 的待侦听频谱, 所述可用频谱为包括待侦听频谱的未 授权频谱, 具体可以为所有的未授权频谱资源, 相应地, 所述向所述 UE 发送侦听配置信息之前, 基站还执行以下操作步骤:
对可用频谱进行干扰侦听, 得到第二侦听结果;
相应地, 基站向 UE发送的侦听配置信息中可以包括所述第二侦听结 果, 以使所述 UE根据所述第二侦听结果确定所述待侦听频谱的描述信息, 或者, 基站根据第二侦听结果, 从可用频谱中选择空闲的频谱并确定空闲 频谱的描述信息从而得到待侦听频谱的描述信息, 并向 UE发送携带待侦 听频谱描述信息的侦听配置信息, 以使所述 UE根据侦听配置信息中的待 侦听频谱的描述信息进行干扰侦听。
由于当基站使用待侦听频谱为其他 UE进行通信时, 基站发送的信号 会对所述 UE的干扰侦听的精准度造成影响, 为排除当前基站发送的信号 对 UE侦听结果的影响, 本实施例的基站还可以发送当前基站对所述待侦 听频谱的使用状态信息, 所述 UE可以根据当前基站对所述待侦听频谱的 使用状态信息, 恢复当前基站发送的信号的能量信息 S , 将对待侦听频谱 上所有信号进行侦听得到的能量信息的值减去当前基站发送的信号的能 量信息 S的值, 从而精确得到待侦听频谱上干扰信号的能量信息, 所述干 扰信号为除所述基站之外的其他设备在待侦听频谱上发送的信号, 干扰信 号的能量信息包括干扰信号的能量 I及噪声 N。
步骤 202 : 根据所述第一侦听结果, 从所述待侦听频谱中选择空闲频谱; 可选地, 在本实施例中, 所述第一侦听结果可以为所述待侦听频谱上的 干扰信号的能量信息, 相应地, 步骤 202 中根据所述第一侦听结果, 从所 述待侦听频谱中选择空闲频谱具体包括:根据所述待侦听频谱上的干扰信号 的能量信息, 从所述待侦听频谱中选择满足预设条件的待侦听频谱。
可选地, 所述第一侦听结果也可以为 UE选择的空闲频谱的描述信息, UE根据干扰侦听得到的待侦听频谱上的干扰信号的能量信息,从待侦听频 谱中选择满足预设条件的待侦听频谱作为空闲频谱, 并将选择的空闲频谱 的描述信息作为第一侦听结果发送给基站, 相应地, 步骤 202 : 根据所述 第一侦听结果, 从所述待侦听频谱中选择空闲频谱, 具体包括: 根据 UE上 报的空闲频谱的描述信息, 从待侦听频谱中选择出所述空闲频谱。
上述的预设条件可以根据需要设定, 将满足预设条件的待侦听频谱确 定为空闲频谱。 由于干扰信号的能量信息的值越小, 对应的频谱越空闲, 待侦听频谱的信干噪比 SINR ( Signal interference noise ratio ) 、 待 侦听频谱的信道质量指示 CQI的值越大该频谱对应的信道质量越好, 频谱 越空闲, 因此, 本实施例中, 所述预设条件具体可以包括以下三项中的至 少一项:
待侦听频谱上的干扰信号的能量信息的值小于第一预设值;
待侦听频谱的信干噪比 SINR的值大于第二预设值, 所述 SINR的值为 所述 UE在当前使用的信道的参考信号接收功率 RSRP与该待侦听频谱上的 干扰信号的能量信息的值的比值, 即 RSRP/ (N+I), 或所述 SINR的值为所 述 UE在当前使用的信道的接收信号能量与该待侦听频谱上的干扰信号的 能量信息的值比值;
待侦听频谱的信道质量指示 CQI大于第三预设值, 所述 CQI的值对应 于所述 UE在当前使用的信道的 RSRP与该待侦听频谱上的干扰信号的能量 信息的值的比值, 或者, 所述 CQI的值对应于所述 UE在当前使用的信道 的接收信号能量与该待侦听频谱上的干扰信号的能量信息的值的比值。
步骤 203: 在所述空闲频谱上与所述 UE进行通信。
优选地, 本实施例中, 通过所述空闲频谱的 SINR或 CQI , 可以辅助基 站在选择的空闲频谱上进行数据调度, 具体的, 基站可以通过所述空闲频 谱的 SINR或者 CQI , 确定和所述 UE在选择的空闲频谱上进行数据通信所 对应的调制编码方案 MCS (Modulator Coder Scheme ) , 并根据所述 MCS, 对所述 UE数据通信数据进行编码调制。
由于处于基站及基站的隐藏节点的共同覆盖范围内的 UE可以侦听到隐藏 节点发送的干扰信号, 因此, 本实施例的方法, 通过 UE对待侦听频谱进行侦 听, 可以扩大基站干扰侦听范围, 发现对于基站而言的隐藏节点, 从而使得 基站可以选择合适的非授权频谱和 UE进行通信, 降低了基站和 UE之间在选 择的非授权频谱上进行通信可能受到的干扰强度。
本实施例的方法可以降低基站的隐藏节点对基站与 UE 之间的通信的影 口向, 根据本实施例的方法, 本领域技术人员容易想到将本实施例中的基站替 换为其他接入点设备, 可以实现降低接入点设备的隐藏节点对该接入点设备 与 UE之间的通信的影响。
