Description

工作载波选择及信息上报方法和设备 本申请要求在 2013年 3月 28日提交中国专利局、 申请号为 201310103243.3、 发明名称为
"工作载波选择及信息上报方法和设备"的中国专利申请的优先权，其全部内容通过引用结合在 本申请中。 技术领域 本申请涉及无线通信领域， 尤其涉及一种工作载波选择及信息上 4艮方法和设备。 背景技术 随着技术发展以及数据业务的爆发式增长， 越来越多的微小区（Pico cell )基站、 家庭 基站（ Home NodeB , He B )等低功率基站被部署用于提供局部的小覆盖， 这类基站可统 称为小小区 （small cell )基站。 部署 small cell不仅可以扩展宏小区 （Macro cell ) 的覆盖， 也能够提升特定区域内的吞吐量。一般地， 网络中部署的 small cell越多， 则有更多的用户 可以被 small cell服务， 享受到 small cell带来的性能增益， 使得网络整体吞吐量得到更大 的提升。 可以预期， 在实际网络中， 4艮可能出现在业务需求集中的地理区域大量密集部署 small cell的情况。
图 1给出了一种在 Macro网络中大量部署 small cell的示意图，其中 Macro cell和 small cell使用不同的频段， 分别为 F1和 F2。 为了支持 small cell覆盖的热点区域的高数据传输 速率， small cell的频段 F2通常使用较高的频率资源 (例如 3.5GHz), 在这些频段上频率资 源相对丰富， 可以使用更多的载波， 釆用载波聚合技术提升 small cell中的峰值速率。
由于 small cell密集部署的特性， small cell之间的相互千扰也会较为严重，相关文稿给 出了一种均匀分布的 small cell部署情况下网络的下行信噪比 （SINR )分布性能， 如图 2 所示。 可以看到， 当每个宏基站覆盖范围内部署了大量的 small cell ( 20个或 50个） 时， small cell的下行 SINR将显著降低， 并有大量终端 （ User Equipment , UE ) 的 SINR小于 0dB。 因此， 如不釆用合理的千扰控制策略， 网络性能将严重下降。

参见图 3 , 本申请实施例针对基站侧提供的工作载波选择方法， 包括以下步骤： 步骤 30: 基站（例如 Pico cell基站、 HeNB等 small cell基站）在特定载波或各载波上 监听信号， 根据信号监听结果得到各载波的使用情况信息； 或者， 接收终端上报的各载波 的使用情况信息； 这里， 各载波是指全部可用载波集合或全部可用载波集合的子集中的各 载波； 载波的使用情况信息包括该载波是否被占用、 该载波上的业务负载等信息。
步骤 31 :基站根据各载波的使用情况信息从各载波中选取至少一个载波作为该基站的 工作载波； 或者， 基站将各载波的使用情况信息上报给中心控制器， 以使中心控制器根据 各载波的使用情况信息为该基站选择工作载波。
步骤 30 中， 基站在特定载波或各载波上监听信号， 根据信号监听结果得到各载波的 使用情况信息， 具体实现可以釆用如下三种方法：
第一， 基站在各载波上监听信号， 根据在各载波上的信号监听结果测量得到对应载波 上的宽带平均接收总功率值， 根据载波上的宽带平均接收总功率值得到该载波上的使用情 况信息。 宽带平均接收总功率值具体可以是接收信号强度指示 （Received Signal Strength Indicator, RSSI )值。
具体的， 若基站在某一个载波上未监听到信号， 则该载波上的宽带平均接收总功率值 为 0, 并确定该载波未被占用； 若基站在某一个载波上监听到信号， 则根据该信号测量得 到的宽带平均接收总功率值越大， 说明该载波正在被较多的基站作为工作载波向外发送信 号或该载波被某一千扰较大的基站占用， 反之说明该载波被较少的基站作为工作载波向外 发送信号或该载波被某一千扰较小的基站占用。
针对一个载波， 基站可以在特定子帧中进行信号监听并测量宽带平均接收总功率值， 也可以在多个子帧中进行信号监听并测量宽带平均接收总功率值。 在多个子帧中进行测量 时， 可以将测量得到的多个宽带平均接收总功率值的平均值作为对应载波的结果值。
基站可以同时 (例如在同一个子帧中） 在各载波上进行信号监听并测量宽带平均接收 总功率值， 或者在不同的时刻针对不同载波进行信号监听并测量宽带平均接收总功率值。
第二， 基站在各载波上监听小区负载标识信号， 其中每个载波上的小区负载标识信号 是将对应载波作为工作载波的其他基站发送的且承载对应载波的小区负载信息的信号； 基 站根据在各载波上监听到的小区负载标识信号得到对应载波的小区负载信息。 这里， 基站 在某个载波上监听到小区负载标识信号的个数可以被认为是占用该载波的基站的数目； 基 站若在某个载波上未监听到小区负载标识信号， 则可以认为该载波未被占用， 负载为 0。
釆用本方法时， 在基站根据各载波的使用情况信息从各载波中选取至少一个载波作 为该基站的工作载波或中心控制器根据各载波的使用情况信息为该基站选择工作载波之 后， 基站在自身的工作载波上发送承载该工作载波的小区负载信息的小区负载标识信号。
第三， 基站在特定载波上监听小区负载标识信号， 其中特定载波上的小区负载标识信 号是其他基站发送的承载该其他基站在其工作载波上的小区负载信息的信号； 基站根据在 特定载波上监听到的小区负载标识信号得到各载波的小区负载信息。 该特定载波可以预先 约定或由网络控制设备（例如 OMC )预先给各基站。 比如， 该特定载波可以是基站可用 的工作频点中的某个频点， 或者是宏基站使用的工作频点。
釆用本方法时， 在基站根据各载波的使用情况信息从各载波中选取至少一个载波作 为该基站的工作载波或中心控制器根据各载波的使用情况信息为该基站选择工作载波之 后， 基站在特定载波上发送承载该基站的在工作载波上的小区负载信息的小区负载标识信 号。
小区负载标识信号可以为物理层控制信息， 该物理层控制信息包含经过编码调制后的 特定长度的信息比特， 该信息比特表示量化后的小区负载信息， 例如， 若小区负载等级为 1 (此时资源利用率 0~25% ), 则该信息比特为 00, 若小区负载等级为 2 (此时资源利用率 25%~50% ), 则该信息比特为 01 , 若小区负载等级为 3 (此时资源利用率 50%~75% ), 则 该信息比特为 10, 若小区负载等级为 4 (此时资源利用率 75%~100% ), 则该信息比特为 11。
或者， 小区负载标识信号还可以为参考信号， 该参考信号的发射功率根据预先设定的 小区负载与信号发射功率之间的对应关系确定。 对于接收小区负载标识信号的基站来说， 该基站根据接收到的小区负载标识信号的发射功率确定该小区负载标识信号所承载的小 区负载信息。 比如， 预先设定的小区负载与信号发射功率之间的对应关系包括： 小区负载 等级 1对应信号发射功率 10, 小区负载等级 2对应信号发射功率 20, 小区负载等级 3对 应信号发射功率 30, 小区负载等级 4对应信号发射功率 40, 则在基站接收到的小区负载 标识信号的发射功率为 10时， 确定该小区负载标识信号所承载的小区负载等级为 1 , 在基 站接收到的小区负载标识信号的发射功率为 20 时， 确定该小区负载标识信号所承载的小 区负载等级为 2, 在基站接收到的小区负载标识信号的发射功率为 30时， 确定该小区负载 标识信号所承载的小区负载等级为 3 , 在基站接收到的小区负载标识信号的发射功率为 40 时， 确定该小区负载标识信号所承载的小区负载等级为 4。 对于发送小区负载标识信号的 基站来说， 该基站根据该小区负载标识信号需要承载的小区负载信息确定小区负载标识信 号的发射功率， 比如， 预先设定的小区负载与信号发射功率之间的对应关系包括： 小区负 载等级 1对应信号发射功率 10, 小区负载等级 2对应信号发射功率 20, 小区负载等级 3 对应信号发射功率 30, 小区负载等级 4对应信号发射功率 40, 则在小区负载标识信号所 需要承载的小区负载等级为 1时， 该小区负载标识信号的发射功率为 10, 在小区负载标识 信号所需要承载的小区负载等级为 2时， 该小区负载标识信号的发射功率为 20, 在小区负 载标识信号所需要承载的小区负载等级为 3时， 该小区负载标识信号的发射功率为 30, 在 小区负载标识信号所需要承载的小区负载等级为 4时， 该小区负载标识信号的发射功率为 40。
较佳的， 为了基站能够区分接收到的小区负载标识信号所对应的小区， 在小区负载标 识信号中还包含对应小区的标识信息。
较佳的， 若基站的工作载波与其他基站的工作载波相同， 则该基站发送小区负载标识 信号时所使用的时频资源与其他基站不相同， 即工作在同一载波的多个基站发送小区负载 标识信号所使用的时频资源是互不相同的； 并且， 基站发送的小区负载标识信号与小区之 间具有对应关系。 基站发送小区负载标识信号时所使用的时频资源可以是预先约定的或是 网络控制实体预先配置的。
小区负载信息可以与小区资源利用率、 激活用户数目等相关， 例如若小区的资源利用 率越高、 激活用户的数目越多， 则小区负载越高。
步骤 31 中， 基站根据各载波的使用情况信息从各载波中选取至少一个载波作为该基 站的工作载波， 具体实现可以如下：
基站根据各载波的使用情况信息确定对应载波是否被其他基站占用和 /或对应载波的 小区负载，按照优先选择被最少基站占用的载波和 /或优先选择负载最低的被占用载波的原 则， 从各载波中选取至少一个载波作为该基站的工作载波。 这里， 在按照优先选择被最少 基站占用的载波和优先选择负载最低的被占用载波的原则为基站选择工作载波时， 可以先 选择被最少基站占用的载波， 若被最少基站占用的载波为多个， 则从该多个载波中选择负 载最低的载波作为基站的工作载波； 或者， 先选择负载最低的被占用载波， 若负载最低的 被占用载波为多个， 则从该多个载波中选择被最少基站占用的载波作为基站的工作载波。
本方法中的中心控制器可以为网络中的基站， 例如宏基站、 small cell基站、 或者其他 网络实体。 基站间传递各载波的使用情况信息时所使用的接口可以是有线接口例如 X2接 口或者 S 1接口， 或者是其他类型的接口例如空中接口等。
参见图 4, 本申请实施例针对终端侧提供的信息上报方法， 包括以下步骤： 步骤 40: 终端在特定载波或各载波上监听信号， 根据信号监听结果得到各载波的使用 情况信息； 这里， 各载波是指全部可用载波集合或全部可用载波集合的子集中的各载波； 载波的使用情况信息包括该载波是否被占用、 该载波上的业务负载等信息。
步骤 41： 终端将各载波的使用情况信息上 4艮给基站或中心控制器， 以使基站或中心控 制器根据各载波的使用情况信息为基站选择工作载波。
步骤 40 中， 终端在特定载波或各载波上监听信号， 根据信号监听结果得到各载波的 使用情况信息， 具体实现可以釆用如下三种方法：
第一， 终端在各载波上监听信号， 根据在各载波上的信号监听结果测量得到对应载波 上的宽带平均接收总功率值， 根据载波上的宽带平均接收总功率值得到该载波上的使用情 况信息； 宽带平均接收总功率值具体可以是 RS SI值。
具体的， 若终端在某一个载波上未监听到信号， 则该载波上的宽带平均接收总功率值 为 0, 并确定该载波未被占用； 若终端在某一个载波上监听到信号， 则根据该信号测量得 到的宽带平均接收总功率值越大， 说明该载波正在被较多的基站作为工作载波向外发送信 号或该载波被某一千扰较大的基站占用， 反之说明该载波被较少的基站作为工作载波向外 发送信号或该载波被某一千扰较小的基站占用。
针对一个载波， 终端可以在特定子帧中进行信号监听并测量宽带平均接收总功率值， 也可以在多个子帧中进行信号监听并测量宽带平均接收总功率值， 在多个子帧中进行测量 时， 可以将测量得到的多个宽带平均接收总功率值的平均值作为对应载波的结果值。
终端可以同时 (例如在同一个子帧中） 在各载波上进行信号监听并测量宽带平均接收 总功率值， 或者在不同的时刻针对不同载波进行信号监听并测量宽带平均接收总功率值。
第二， 终端在各载波上监听小区负载标识信号， 其中每个载波上的小区负载标识信号 是将对应载波作为工作载波的基站发送的且承载对应载波的小区负载信息的信号； 终端根 据在各载波上监听到的小区负载标识信号得到对应载波的小区负载信息。 这里， 终端在某 个载波上监听到小区负载标识信号的个数可以被认为是占用该载波的基站的数目； 终端若 在某个载波上未监听到小区负载标识信号， 则可以认为该载波未被占用， 负载为 0。
第三， 终端在特定载波上监听小区负载标识信号， 其中特定载波上的小区负载标识信 号是基站发送的承载该基站的在工作载波上的小区负载信息的信号； 终端根据在特定载 波上监听到的小区负载标识信号得到各载波的小区负载信息。 该特定载波可以预先约定或 由网络控制设备预先给各基站。 比如， 该特定载波可以是基站可用的工作频点中的某个频 点， 或者是宏基站使用的工作频点。
具体的， 小区负载标识信号为物理层控制信息， 该物理层控制信息包含经过编码调制 后的特定长度的信息比特， 该信息比特表示量化后的小区负载信息； 或者，
小区负载标识信号为参考信号， 该参考信号的发射功率根据预先设定的小区负载与信 号发射功率之间的对应关系确定。 终端可以根据接收到的小区负载标识信号的发射功率确 定该小区负载标识信号所承载的小区负载信息。
较佳的， 小区负载标识信号中还包含对应小区的标识信息。
本方法中的中心控制器可以为网络中的基站， 例如宏基站、 small cell基站、 或者其他 网络实体。
参见图 5 , 本申请实施例针对中心控制侧提供的工作载波选择方法， 包括以下步骤： 步骤 50: 中心控制器接收基站或终端上报的各载波的使用情况信息； 这里， 载波的使 用情况信息可以包括该载波是否被占用、 该载波上的业务负载等信息。
