Description

一种无线资源管理的测量方法、 设备及系统 技术领域
本发明涉及通信领域， 尤其涉及一种无线资源管理的测量方 法、 设备及系统。 背景技术
LTE ( Long Term Evolution , 长期演进 ） 系统基于 OFDM ( Orthogonal Frequency Division Multiplexing，正交频分复用 )技术, 即利用该 OFDM技术将时频资源划分为时间域维度上的 OFDM符号 和频域维度上的 OFDM子载波。 为了维持 LTE系统中的业务传输， UE 需要根据基站发送的参考信号进行同步， 信道状态测量和 RRM ( Radio Resource Management , 无线资源管理） 测量。 具体的， 该 RRM测量包括 RSRP (Reference Signal Received Power , 参考信号接 收功率）、 RSRQ (Reference Signal Received Quality , 参考信号接收 质量）和 RS SI(Received Signal Strength Indicator ,接收信号强度指示） 测量， 其中 RSRP 表示 目 标被测量小 区的 CRS ( Cell-specific Reference Signal , 小区特定参考信号） 资源单元上所包含的目标被 测小区发送的 CRS 的平均接收功率； RS SI 表示目标被测量小区的 CRS所在的 OFDM符号上所有信号的平均接收功率； RSRQ则是根 据 RSRP与 RS SI的比值获得的。 此外， 现有的 LTE系统对基站的功 率效率要求较高， 且在将来的网络拓朴演进中， 运营商会大量部署 异构网络， 因此现今一个主流的异构网络包括： 一个宏基站以及在 该宏基站范围内的大量小小区。
在上述密集小小区的异构网络中， 由于网络设备的密集使得大 量小小区范围内并没有需要服务的 UE , 同时当所有小小区都处于开 启状态时， 即便没有业务传输但各小小区仍然向外发送周期较短的 参考信息 (如 PS S ( Primary Synchronization Signal , 主同步信号 ) , S SS ( Secondary Synchronization Signal , 辅同步信号 ） 和 CRS ( Cell-specific Reference Signal , 小 区特定参考信号 ）、 RCRS ( Reduced CRS , 减少的小区特定参考信号）， 其中 PS S/SS S/ RCRS 的发送周期为 5个子帧， CRS的发送周期为 1个子帧 ）， 而这些参考 信息会造成小区间干扰严重。 这样， 一个潜在的方案是将这些没有 服务 UE 的小小区关闭， 使其不能发送上述周期较短的参考信息， 从而达到节能和降低小区间干扰的作用。
但是， 发明人发现， 在对上述小小区进行关闭或开启时， 会导 致一个区域内相邻小区间的干扰环境发生较快的变化或抖动， 从而 增加了 RRM的测量的难度， 给 RRM测量提出了更高的要求， 使得 UE不能高效的进行本小区和邻小区的小区选择， 重选或切换。 发明内容

具体实施方式 下面将结合本发明实施例中的附图， 对本发明实施例中的技术 方案进行清楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明 一部分实施例， 而不是全部的实施例。 基于本发明中的实施例， 本 领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他 实施例， 都属于本发明保护的范围。
本发明所提供的实施例应用于 LTE ( Long Term Evolution , 长 期演进） 系统， 该 LTE 系统基于 OFDM ( Orthogonal Frequency Division Multiplexing , 正交频分复用 ） 技术， 即利用该 OFDM技术 将时频资源划分为时间域维度上的 OFDM 符号和频域维度上的 OFDM子载波， 所形成的最小资源粒度叫做 RE ( Resource Element , 资源单元）， 该资源单元表示时间域上的一个 OFDM 符号和频率域 上的一个 OFDM子载波的时频格点。 同时 LTE系统中业务的传输是 基于基站调度的， 一般是基站发送控制信道， 该控制信道可以承载 上行或下行数据数据信道的调度信息， 该调度信息包括资源分配信 息或调制编码方式等控制信息， 而 UE ( User Equipment , 用户设备） 在接收到上述的控制信道所承载的调度信息后， 会根据该调度信, ¾ 进行下行数据信道的接收或上行数据信道的发送。 其中基站调度 UE 是以资源块 （ RB , Resource Block ) 为粒度来进行的， 一个资源块 在时间域上占用一个子帧的长度， 频率域上占 12 个 OFDM 子载波 的宽度， 一个子帧一般包括 14个 OFDM符号。
进一步的， 为了维持 LTE系统中的业务传输， UE需要根据基 站发送的参考信号进行同步、信道状态测量和 RRM ( Radio Resource Management , 无线资源管理） 测量。 其中， 同步又分为初始粗同步 和时频跟踪精同步， 初始粗同步是根据基站发送的 PS S ( Primary Synchronization Signal , 主 同 步 信 号 ) 和 S S S ( Secondary Synchronization Signal , 辅同步信号） 来完成的， 而时频跟踪精同步 是通过基站发送的 CRS ( Cell-specific Reference Signal , 小区特定参 考信号） 来完成的。 信道状态测量包括信道测量和干扰测量， 一般 是通过 CRS或 RCRS ( Reduced CRS , 减少的小区特定参考信号）来 测量。 其中， RCRS是将当前每个子帧都会发送的 CRS 的周期修改 为 N ms的 CRS , N可以为 5或其他整数， 即后续 LTE系统中的 CRS 可能不会每个子帧都被发送， 而是以 N ms (N> 1 )为周期来发送， 此 时的 CRS叫 RCRS。 RRM测量包括 RSRP (Reference Signal Received Power , 参考信号接收功率）、 RSRQ (Reference Signal Received Quality , 参考信号接收质量）和 RS SI(Received Signal Strength Indicator , 接收信号强度指示）测量， 其中 RSRP 表示目标被测量小 区的 CRS ( Cell-specific Reference Signal , 小区特定参考信号） 资源 单元上所包含的目标被测小区发送的 CRS 的平均接收功率； RS SI 表示目标被测量小区的 CRS所在的 OFDM符号上所有信号的平均接 收功率， 包括本小区信号接收功率， 同频邻小区信号接收功率， 异 频段泄露到本频段的信号接收功率和热噪声等所有信号的平均功 率； RSRQ则是根据 RSRP与 RSSI的比值获得的。
此外， 现有的 LTE系统对基站的功率效率要求较高， 且在将来 的网络拓朴演进中， 运营商会大量部署异构网络， 因此现今一个主 流的异构网络包括： 一个宏基站以及在该宏基站范围内的大量小小 区， 其中， 宏基站主要提供覆盖和实时数据业务， 小小区主要提供 高速率的数据业务， 且宏小区和小小区可以釆用相同或不同的频点 部署， 但以不同频点的部署场景为主。 同时在上述密集小小区的异 构网络中， 由于网络设备的密集使得大量小小区范围内并没有需要 服务的 UE , 同时当所有小小区都处于开启状态时， 即便没有业务传 输但各小小区仍然向外发送周期较短的参考信息（如 PS S , SS S , CRS 和 RCRS , 其中 PSS/SS S/ RCRS的发送周期为 5个子帧， CRS的发 送周期为 1 个子帧））， 而这些参考信息会造成小区间干扰严重。 这 样， 一个潜在的方案是将这些没有服务 UE 的小小区关闭， 使其不 能发送上述周期较短的参考信息， 从而达到节能和降低小区间干扰 的作用。 但是， 发明人发现， 在对上述小小区进行关闭或开启时， 会导致一个区域内相邻小区间的干扰环境发生较快的变化或抖动， 从而增加了 RRM的测量的难度， 给 RRM测量提出了更高的要求， 使得 UE不能高效的进行本小区和邻小区的小区选择， 重选或切换。 因此， 如何更高效的进行 RRM测量是现今所要解决的首要问题。
但是， 反观上述技术方案， 如果小小区将这些没有服务 UE的 小区彻底关闭， UE是无法及时的发现被关闭的小小区， 也无法对其 进行 RRM测量， 这样小小区就无法确定其何时再开启。 因此， 基于 上述方案， 一个优选的方案是让这些没有服务 UE 的小小区以较长 的周期来发送一个 DRS ( Discovery Reference Signal , 发现参考信 号 ) ,从而使得该关闭的小小区周围的 UE可以根据该 DRS对该关闭 的小小区进行及时发现和 RRM 测量。 而且为了降低 UE 利用 DRS 做 RRM测量的功耗， 通常是让多个小小区同步发送 DRS , 这样 UE 就只需要在这个时间窗内利用 DRS做 RRM测量， 就可以同时获取 多个小小区的 RRM测量结果。 为了方便理解， 本文在以下的描述过 程中， 将上述处于关闭但发送 DRS的状态称为休眠态， 此时不发送 周期较短的参考信号， 该参考信号包括 PSS , S SS , CRS/RCRS , 用 作 CSI测量的 CSI-RS 中的至少一种， 或者此时除了 DRS之外其他 信号都不发送； 将开启后正常服务 UE 的状态称为的激活态， 此时 需要发送 PS S , SS S , CRS/RCRS , 用作 CSI 测量的 CSI-RS 中的至 少一种。
另外， 基于上述描述， 当 目标被测小区相邻的小小区中存在较 多的休眠态的小小区， 且这些小区同步发送 DRS时， 处于休眠态的 小小区除了较长周期发送的 DRS时刻的发送功率不为 0之外， 其他 时段的发送功率均为 0 , 但上述小小区在发送 DRS这一时刻的发送 功率， 由于同步 DRS发送机制被算在了 RS SI中， 从而高估了 RS SI 值， 进而低估了利用该 RSSI所得到的 RSRQ或 SINR值。 因此， 发 明人发现， 无论目标被测小区在根据 DRS进行 RRM测量时处于激 活态还是休眠态， 目标被测小区根据 DRS 所测得的 RSRQ或 SINR 均会被低估， 从而导致较好的本该服务该 UE 的小小区不能够服务 该 UE。
因此， 针对上述 RSRQ或 SINR值被低估的应用场景， 本发明 的实施例提供了一种无线资源管理的测量方法， 应用于用户设备侧， 如图 1所示， 该无线资源管理的测量方法具体包括如下步骤：
101、 UE检测第一参考信号， 并根据检测到的第一参考信号确 定该检测到的第一参考信号对应的目标小区及该检测到的第一参考 信号所在的第一资源。
其中， 上述的第一参考信号为 DRS , —般发送周期较长， 比如 远大于 5 ms或 10 ms , 比如几十或几百 ms甚至几千 ms , 用于测量 RSRP , 并位于第一资源上， 该 DRS 具体可以基于现有的参考信号 来设计， 如 PRS , CSI-RS , CRS , RCRS , PSS和 S SS 中的至少一种， 也可以是基于上述现有参考信号进行一些优化， 比如序列不变但通 过灵活配置现有参考信号的时频资源来作为上述 DRS。 此外， 该检 测到的第一参考信号所在的第一资源可以为承载该检测到的第一参 考信号的资源单元， 因此， UE在检测完该第一参考信号后， 便可将 该检测到的第一参考信号的资源单元确定为第一资源。
102、 U E根据第一资源上承载的该检测到的第一参考信号的接 收功率确定目标小区的参考信号接收功率 RSRP。
103、 UE确定第二资源。
其中， 当上述的目标小区处于激活态时， 该目标小区在第二资 源上至少承载第二参考信息； 和 /或者， 当上述的目标小区处于休眠 态时， 该目标小区在第一资源上承载该检测到的第一参考信号， 且 在第二资源上未承载第二参考信息， 但该目标小区从休眠态转入激 活态， 那么在第二资源上会承载上述第二参考信息。
可选的， 该第二资源上只要不承载上述第一参考信号就可以， 即第二资源为不承载第一参考信号的任意资源， 可以承载或不承载 上述第二参考信息。 如果不承载第二参考信息， 那么第二资源上的 功率由动态的调度的数据信道来确定， 即有数据调度就会有功率， 否则可能就没有功率， 此时更可以反映出真实的数据信道带来的干 扰影响。 当然， 如果第二资源承载第二参考信息， 该第二参考信息 不依赖于动态数据调度， 而是只要该目标小区处于激活态， 那么就 会发送上述第二参考信息， 此时测量到的干扰未必能真实的反映出 数据信道的干扰， 但测量到的干扰比较稳定， 不会抖动很大， 便于 网络侧拿到 UE测量到的结果后的使用， 比如对该 UE进行添加或删 除小区， 切换等。
而上述的第二资源指的是目标小区的第二参考信息所在的整 个 OFDM符号上的全部或部分资源单元， 也可以是该第二参考信息 所在的时隙， 子帧或子帧集合中的多个 OFDM符号； 该第二参考信 息包括： CSI-RS , CRS , RCRS , PSS , S SS , PRS和广播信道中的至 少一种。 具体的， 当该目标小区处于激活态时， 该目标小区在第二 资源上至少承载第二参考信息； 而当该目标小区处于休眠态时， 由 于该目标小区不会发送第二参考信息， 即该目标小区的传输帧中只 存在第一参考信号， 因此， 该目标小区在第一资源上承载第一参考 信号， 在第二资源上未承载第二参考信息， 或者， 第二资源为该目 标小区处于激活态时发送的第二参考信息所在的资源。
需要说明的是， 对于上述的广播信道， 由于只有处于激活态的 小区才会发送广播信道， 且该广播信道的发送是周期性的， 因此，
UE根据该广播信道进行 RRM测量的方法， 与根据其他参考信号进 行 RRM测量的方法相同。
104、 UE根据该第二资源上的总接收功率确定目标小区的接收 信号强度指示 RSSI。
其中， 上述的第一资源和上述的第二资源在不同的时刻。 具体 的， 该第一资源和该第二资源属于不同的 OFDM符号或不同的时隙 或不同的子帧或不同的子帧集合。
105、 UE根据 RSRP和 RSSI确定目标小区的参考信号接收质 量 RSRQ和 /或信号与干扰加噪声比 SINR。
需要说明的是， 如果目标小区处于激活态， 那么该目标小区上 会发送 DRS , PSS , SS S , CRS , RCRS , CSI-RS , PRS , 广播信道中 的至少一种， 这样可以供 UE 随时接入或驻留到该目标小区上； 如 果该目标小区处于休眠态， 那么该休眠小区上只会发送第一参考信 号， 即 DRS , 且该 DRS 的发送周期会比上述激活态需要发送的第 二参考信号的周期要长得多， 一般会是几百子帧甚至几千子帧的周 期。这样就会出现多个小区同步发送 DRS ,从而使得测量出的 RSRQ 或 SINR 被低估的问题， 该问题可以釆用上述分别在第一资源和第 二资源上测量 RSRP和 RS SI来解决。
或者， 若目标小区处于激活态， 那么该目标小区上会发送 PSS , SS S , CRS , RCRS , CSI-RS , PRS , 广播信道中的至少一种， 而不 发送 DRS； 则此时 UE可以根据 PSS和 S SS进行小区识别， 并根据 CRS或 RCRS做 RRM测量。 若目标小区处于休眠态， 那么该目标小 区上除了发送 DRS 之外， 还可以发送 RCRS 或 CRS , 该 RCRS 或 CRS的发送周期可能比激活态时的发送周期长， 比如周期跟 DRS相 同， 而用来供 UE做 RRM测量， 或者辅助 DRS—起做 RRM测量。
本发明实施例中的第一资源和第二资源属于时间资源和 /或频 率资源。
本发明的实施例提供的无线资源管理的测量方法， 通过第一资 源上承载的第一参考信号的接收功率所确定的目标小区的参考信号 接收功率 RSRP , 以及第二资源上的总接收功率所确定的目标小区的 接收信号强度指示 RS SI , 来确定目 标小区的参考信号接收质量 RSRQ 和 /或信号与干扰加噪声比 SINR , 相比于现有技术中只根据 CRS或 DRS来测量目标小区的 RSRQ或 SINR , 并会导致一个区域 内相邻小区间的干扰环境发生较快的变化或抖动， 本发明所提供的 无线资源管理的测量方法则效率更高。 此外， 针对现有技术中 UE 测量出的 RSRQ 或 SINR会被低估的问题， 本发明提供的第一资源 与第二资源存在时刻差，使得目标小区的 RS SI中并没有包含处于休 眠态小区 （ 目标小区， 和 /或该目标小区的邻区 ） 的功率， 从而避免 上述 RSRQ和 /或 SINR被低估， 进而提高了无线资源管理测量的正 确率。 本发明的实施例提供的无线资源管理的测量方法，如图 2所示， 该无线资源管理的测量方法具体包括如下步骤：
201、 UE获取第一参考信号的配置信息。
其中， 上述的配置信息包括第一参考信号的候选序列和 /或第 一参考信号的候选时频资源。 该候选时频资源可以是定时， 带宽， 时频单元图案等等。 同时， 该配置信息可以是 UE 预先配置的， 也 可以是 UE的服务小区对应的基站通知的。
具体的， 当 UE的服务小区为频点为 fl 的宏小区， 而该目标小 区为频点为 f2的小小区时， 该服务小区会配置 UE在 f2频点上对小 小区进行测量。 同时为了降低 UE 测量的复杂度和功耗， 服务小区 会辅助性的通知 UE该小小区的一些配置信息， 如通过 RRC专有信 令通知 UE该小小区的第一参考信号的候选序列， 以便 UE可以根据 该第一参考信号的候选序列检测到该第一参考信号， 其中该候选序 列包括但不限于： Gold序列和 Zad-off Chu序列； 和 /或， 通过 RRC ( Radio Resource Control , 无线资源控制协议）专有信令通知 UE该 小小区发送第一参考信号时的发送定时， 以便 UE 可以根据该第一 参考信号的发送定时确定检测时间； 和 /或， 通过 RRC 专有信令通 知 UE该小小区的第一参考信号的发送带宽； 和 /或， 通过 RRC专有 信令通知 UE该小小区的第一参考信号在资源块中的时频资源图案。 其中， 服务小区通知 UE 该小小区发送第一参考信号的发送定时， 主要是由于该第一参考信号 （如 DRS ) 的发送周期一般较长 （如几 百个子帧 ）， 因此若是 UE每个子帧都去检测该第一参考信号， 会造 成 UE对第一参考信号进行检测的检测时间变长， 同时增加了 UE的 功耗。 此外， 服务小区通知 UE 该小小区发送第一参考信号的发送 定时除了可以是具体的发送时间， 也可从是服务小区的无线帧号， 具体的， 服务小区在该服务小区的无线帧号 （如， 0或 20或 40等） 的位置处发送第一参考信号， 并将该服务小区的无线帧号发送至 UE , 以便该 UE根据与该服务小区的同步关系推测出小小区的第一 参考信号的发送定时。 另外， 由于服务小区和小小区可能不会完全 同步， 因此， 上述的发送定时可能是粗略的定时， 但即便如此， 该 第一参考信号的发送定时的发送也可以大大减小 UE 检测该第一参 考信号的检测时间和功耗。
202、 UE检测第一参考信号， 并根据检测到的第一参考信号确 定该检测到的第一参考信号对应的目标小区及该检测到的第一参考 信号所在的第一资源。
其中， 上述的第一参考信号包括 DRS , 该 DRS 可以基于现有 参考信号设计， 如 PRS , CSI-RS , CRS , RCRS , PSS和 SS S 中的至 少一种， 也可以是基于上述现有参考信号进行一些优化， 比如序列 不变但通过灵活配置现有参考信号的时频资源来作为上述 DRS。
可选的， 步骤 202具体包括如下步骤： 202a, UE根据第一参考信号的配置信息检测该第一参考信号。 202b , UE 根据检测到的第一参考信号的配置信息确定该检测 到的第一参考信号对应的目标小区及该检测到的第一参考信号所在 的第一资源。
具体的， 首先 UE根据预先配置或 UE的服务小区对应的基站 通知获取到该第一参考信号的配置信息后， 便可根据该配置信息检 测该第一参考信号。 例如， UE在被通知的第一参考信号的某个发送 定时及被通知的小小区频点的某个带宽内， 检测多个第一参考信号 的候选序列， 比如用 10个候选序列去——匹配， 最终检测到某个第 一参考信号的序列后， 即其中一个候选序列匹配成功， 便可根据预 先获取的该第一参考信号的配置信息中的该第一参考信号的序列与 小区标识之间的对应关系 , 和该匹配成功的实际序列确定 UE 所检 测到的第一参考信号的实际序列所对应的小区标识， 即识别到 目标 小区。 当然 UE 也可以通过该第一参考信号的序列及资源单元图案 来确定小区标识 , 进而识别到目标小区。 其次， UE在识别到目标小 区后， 便在目标小区的传输帧中确定该第一参考信号所属子帧， 然 后从该第一参考信号所述子帧的资源块中确定该第一参考信号所在 的第一资源， 即承载该检测到的第一参考信号的资源单元。
203、 U E根据第一资源上承载的该检测到的第一参考信号的接 收功率确定目标小区的参考信号接收功率 RSRP。
具体的， 将第一资源上的第一参考信号的功率取平均值， 比如 承载第一参考信号的 10个资源单元， 则取这 10个资源单元上的第 一参考信号的平均接收功率为 RSRP。
204、 UE确定第二资源。
具体的， UE 在确定了上述的目标小区的第一参考信号的第一 资源后， 还需要确定第二资源。 其中， 上述的第二资源指的是目标 小区的第二参考信息所在的整个 OFDM符号上的全部或部分资源单 元， 或也可以包括上述 OFDM符号所在的时隙、 子帧、 子帧集合或 无线帧。 而该第二参考信息包括： CSI-RS , CRS , RCRS , PSS , SS S , PRS 和广播信道中的至少一种。 具体的， 当该目标小区处于激活态 时， 该目标小区在第二资源上至少承载第二参考信息； 而当该目标 小区处于休眠态时， 由于该目标小区不会发送第二参考信息， 即该 目标小区的传输帧中只存在第一参考信号， 因此， 该目标小区在第 ―资源上承载该检测到的第一参考信号， 在第二资源上未承载第二 参考信息。 但该目标小区从休眠态转入激活态， 那么在第二资源上 会承载上述第二参考信息。
可选的， 该第二资源上只要不承载上述第一参考信号就可以， 即第二资源为不承载第一参考信号的任意资源， 可以承载或不承载 上述第二参考信息。 如果不承载第二参考信息， 那么第二资源上的 功率由动态的调度的数据信道来确定， 即有数据调度就会有功率， 否则可能就没有功率， 此时更可以反映出真实的数据信道带来的干 扰影响。 当然， 如果第二资源承载第二参考信息， 该第二参考信息 不依赖于动态数据调度， 而是只要该目标小区处于激活态， 那么就 会发送上述第二参考信息， 此时测量到的干扰未必能真实的反映出 数据信道的干扰， 但测量到的干扰比较稳定， 不会抖动很大， 便于 网络侧拿到 UE测量到的结果后的使用， 比如对该 UE进行添加或删 除小区， 切换等。
需要说明的是， 对于上述的广播信道， 由于只有处于激活态的 小区才会发送广播信道， 且该广播信道的发送是周期性的， 因此， UE根据该广播信道进行 RRM测量的方法， 与根据其他参考信号进 行 RRM测量的方法相同。
可选的， 步骤 204具体包括：
204a, UE根据第一资源与资源偏移量确定第二资源。
其中， 上述的资源偏移量包括时域偏移和 /或频率偏移， 该资 源偏移量可以是 UE预先配置的，也可以是 UE的服务小区对应的基 站通过辅助 RRC信令通知的。 具体的， UE在确定上述的第二资源 时， 可以根据第二资源与第一资源之间的资源偏移量 （例如， 第二 资源与第一资源所在 OFDM符号之间存在 N个 OFDM符号间隔，或 者， 第二资源与第一资源所在子帧之间存在 N个子帧间距）来确定。 这样， UE在确定了第一资源之后， 就可以根据上述资源偏移量确定 第二资源的时域位置。 而在确定第二资源的频率位置时， 可以预先 进行配置， 也可以与第一资源占用相同的频率位置， 也可以与第一 资源存在频率上的偏移量等， 这里不做具体限定。
205、 UE根据该第二资源上的总接收功率确定目标小区的接收 信号强度指示 RSSI。
具体的， UE测量第二参考信息所在 OFDM符号上的接收总功 率， 该接收总功率包括该 OFDM鼓号上所有信号的接收功率， 该所 有信号包括目标小区的接收功率， 及该目标小区的邻区在该 OFDM 符号上的功率和噪声等。 即 UE不区分该 OFDM符号上的不同信号， 只是测量该 OFDM符号上的接收功率， 并把上述的接收功率在多个 OFDM 符号上取平均值作为该目标小区的 RSSI , 当然这里也可以不 做平均， 具体计算方式这里不做限制。 只要 UE根据该 OFDM符号 上的总接收功率来确定目标小区的 RS SI 即可， 甚至可以将上述 OFDM符号上的接收功率平均到整个子帧的 14 个 OFDM符号上或 更多的子帧上， 来平均计算该目标小区的 RS SI。
其中， 上述的第一资源和上述的第二资源在不同的时刻。 具体 的， 该第一资源和该第二资源属于不同的 OFDM符号或不同的时隙 或不同的子帧或不同的子帧集合， 只要该第一资源和该第二资源在 时域上不同即可， 其他不做限定。
206、 UE根据 RSRP和 RSSI确定目标小区的参考信号接收质 量 RSRQ和 /或信号与干扰加噪声比 SINR。
具体的， UE 在确定了 RSRP 及 RSSI后， 便可根据 RSRP 和 RSSI的比值， 即 RSRP除以 RSSI , 来进一步确定 RSRQ或 SINR。 其中， UE可以直接将上述比值作为 RSRQ或 SINR , 也可以在上述 比值上再乘以一个系数作为 RSRQ或 SINR。 而该系数可以根据当前 的测量带宽来确定， 也可以根据平均化参数来确定。 当根据当前的 测量带宽来确定系数时， 该测量带宽越宽， 则该系数越大； 或者， 当根据平均化参数来确定系数时， 该平均化参数可以为测量 RSRP 或 RS SI的符号上的接收功率在整个子帧的 14个 OFDM符号上的平 均值，也可以为测量 RSRP或 RSSI的符号上的接收功率在 N个子帧 的 N* 14个 OFDM符号上平均值。需要说明的是，由于 RSSI在 RSRQ 或 SINR计算的分母上， 且目标小区的 RSSI中没有包括休眠态小区 的功率， 因此， 相比于休眠态小区的 DRS 功率被计算到 RS SI 中而 言， 本发明最终所确定的 RSRQ或 SINR则不会被低估。
进一步的， 对于 SINR测量， 上述第二资源不仅可以是第二参 考信息所在的 OFDM符号， 还可以是第二参考信息所在的时隙， 还 可以是第二参考信息所在的子帧或子帧集合中的部分频率上的资源 单元。 例如， 若以第二资源为 RCRS所在的 OFDM符号为例， 不同 小区在相同的测量频带内分别占用上述 OFDM的不同频域位置 (比 如， 在 RCRS所在 OFDM符号的不同的子载波）， 这样对于目标小区 的干扰或干扰加噪声， 只需要在上述 OFDM符号中 目标小区所对应 的子载波测量接收功率即可。 但是由于该子载波位置处该目标小区 不发送信号， 因此 UE 在此位置处测量到的是其他小区对目标小区 所产生的干扰。 此外， 由于目标小区在处于休眠态时， 第二资源上 并未承载该目标小区的第二参考信息， 所以上述 UE 所测量到的干 扰或干扰加噪声也不包括休眠态小区的功率， 因此 UE 最终得到的 SINR也不会被低估。
可选的， 步骤 206具体包括： 若目标小区在第二资源上的发送 功率不为 0 , 则 UE根据 RSRP和 RSSI确定目标小区的 RSRQ ; 和 / 或， 若目标小区在第二资源上的发送功率为 0 , 则 UE根据 RSRP和 RSSI确定目标小区的 SINR。
具体的， 如果目标小区在第二资源上的发送功率不为 0 , 则 UE 根据 RSRP和 RS SI确定第一小区的 RSRQ , 因为此时目标小区的第 二资源上的功率不为 0 , 即第二资源上承载的第二参考信息的功率 不为 0。 如果目标小区在第二资源上的发送功率为 0 , 则 UE 根据 RSRP和 RS SI确定目标小区的 SINR ,因为此时目标小区的第二资源 上的功率为 0 , 即第二资源上上不承载第二参考信息。
进一步的， 如果小小区的开关或状态转换对于 UE来说是透明 的， 即 UE在做小小区的 RRM测量时不会感知到小小区的处于激活 态或休眠态，那么如果目标小区为激活态，则测量到的结果为 RSRQ ; 如果为休眠态， 则测到的结果为 SINR。 这样， 如果 UE将多次 DRS 的测量结果进行平均， 即将 RSRQ和 SINR的结果进行了平均处理， 这种处理会发生在目标小区的状态转换期间， 这样会导致测量结果 不够准确，即既不能准确的反应出 RSRQ也不能准确的反应出 SINR , 而是两者的平均值， 可能对后续基站使用 UE 上报的该结果造成影 响。
解决上述进一步问题的方法可以为： UE 确定多个时间窗， 该 时间窗的起点和长度可以预定义或基站通知， 那么 UE 只允许在每 个时间窗内进行 RRM测量结果的平均处理。 相应的， 目标小区也只 会在多个窗的边界处进行状态转换， 这样可以保证 UE 在每个窗内 测量平均后得到的结果要么都是 RSRQ , 要么都是 SINR, 这样对于 两者的测量都是准确的。
可选的， 在步骤 206之后， 还包括：
207a、UE将 RSRQ上报至基站，以便基站根据 UE上报的 RSRQ 确定是否将目标小区从休眠态切换至激活态， 和 /或， 根据 UE上报 的 RSRQ确定是否将目标小区配置给 UE。
或者，
207b、 UE将 SINR上 4艮至基站， 以便基站根据 UE上^艮 SINR 确定是否将目标小区从休眠态切换至激活态， 和 /或， 根据 UE上报 的 SINR确定是否将目标小区配置给 UE。
或者，
207c、 UE将 RSRQ和 SINR上 4艮至基站， 以便基站根据 UE上 报的 RSRQ 和 SINR确定是否将目标小区从休眠态切换至激活态， 和 /或， 根据 UE上报的 RSRQ和 SINR确定是否将目标小区配置给 UE。 具体的，由于 UE在不同的应用场景下最终测量得到上述 RSRQ 和 /或 SINR ( 即只测量到 RSRQ , 或者， 只测量得到 SINR , 或者， 同时测量到 RSRQ和 SINR) 后， UE可以将目标小区的测量结果上 报给该 UE 的服务小区 （ 比如宏小区 ） 对应的基站， 而基站在接收 到该 RSRQ和 /或 SINR之后， 会根据 UE上报的测量结果， 来确定 是否将该测量结果对应的目标小区配置给该 UE, 如果该目标小区处 于休眠态， 则基站还可以确定是否将该目标小区由休眠态切换到激 活态， 并配置给该 UE。
需要说明的是， 如果目标小区处于激活态， 那么该目标小区上 会发送 DRS, PSS, SSS, CRS, RCRS, CSI-RS, PRS, 广播信道中 的至少一种， 这样可以供 UE 随时接入或驻留到该目标小区上； 如 果该目标小区处于休眠态， 那么该休眠小区上只会发送第一参考信 号， 比如 DRS, 且该 DRS的发送周期会比上述激活态需要发送的第 二参考信号的周期要长得多， 一般会是几百子帧甚至几千子帧的周 期。这样就会出现多个小区同步发送 DRS,从而使得测量出的 RSRQ 或 SINR 被低估的问题， 该问题可以釆用上述分别在第一资源和第 二资源上测量 RSRP和 RS SI来解决。
或者， 若目标小区处于激活态， 那么该目标小区上会发送 PSS, SSS, CRS, RCRS, CSI-RS, PRS, 广播信道中的至少一种， 而不 发送 DRS； 则此时 UE可以根据 PSS和 SSS进行小区识别， 并根据 CRS或 RCRS做 RRM测量。 若目标小区处于休眠态， 那么该目标小 区上除了发送 DRS 之外， 还可以发送 RCRS 或 CRS, 该 RCRS 或 CRS的发送周期可能比激活态时的发送周期长， 比如周期跟 DRS相 同， 而用来供 UE做 RRM测量， 或者辅助 DRS—起做 RRM测量。
本发明的实施例提供的无线资源管理的测量方法， 通过第一资 源上承载的第一参考信号的接收功率所确定的目标小区的参考信号 接收功率 RSRP,以及第二资源上的总接收功率所确定的目标小区的 接收信号强度指示 RSSI, 来确定目 标小区的参考信号接收质量 RSRQ 和 /或信号与干扰加噪声比 SINR, 相比于现有技术中只根据 CRS或 DRS来测量目标小区的 RSRQ或 SINR , 并会导致一个区域 内相邻小区间的干扰环境发生较快的变化或抖动， 本发明所提供的 无线资源管理的测量方法则效率更高。 此外， 针对现有技术中 UE 测量出的 RSRQ 或 SINR会被低估的问题， 本发明提供的第一资源 与第二资源存在时刻差，使得目标小区的 RS SI中并没有包含处于休 眠态小区 （ 目标小区， 和 /或该目标小区的邻区 ） 的功率， 从而避免 上述 RSRQ和 /或 SINR被低估， 进而提高了无线资源管理测量的正 确率。 具体的， 这里提供了三种应用场景下的无线资源管理的测量方 法， 且参照图 3、 4、 5可知， 其中第一参考信号以 DRS为例， 第二 参考信息以 RCRS 为例， 目标小区以小区 0 为例， 邻小区以小区 1 和小区 2为例。
在第一种应用场景下 （即目标小区为激活态， 同时该目标小区 的 DRS与 RCRS处于不同子帧 ）：
首先， UE根据预先获取的 DRS的配置信息检测到小区 0后， UE确定该小区 0的 DRS所在的第一资源，即图 3所示的 4个 OFDM 符号上的总共 16个 RE ,再测量该 16个 RE上的 DRS的平均接收功 率，并将该平均接收功率作为该小区 0的 RSRP。这里需要注意的是， 小区 0的 DRS所在的 16个 RE上可能还会包括其他小区在相同资源 上发来的干扰信息和噪声， 但这里只需要测量 16个 RE上所包含的 该小区 0的 DRS的平均接收功率， 不将上述干扰功率和噪声功率计 算在 RSRP之内。
然后， 根据预设的第一资源与第二资源之间的资源偏移量， 及 第一资源在子帧资源块中的位置来确定第二资源， 由于小区 0 处于 激活态， 则该第二资源为 RCRS所在 OFDM符号上的所有资源。 即 图 3 中所示的第一资源与第二资源的位置， 可以看出第二资源与第 一资源相隔 4个子帧， 该第二资源为 RCRS所在 4列 OFDM符号上 的 RE。 UE 在确定了第二资源的位置后，便测量该 RCRS所在 OFDM 符号上的总接收功率， 该总接收功率包括该 0 F D M符号上的所有信 号的接收功率， 并把该上述的接收功率在多个 OFDM符号上取平均 值作为该小区 0的 RSSI , 当然也可以不做平均， 这里不做限制。
如图 3所示， 被测小区小区 0是激活态， 激活态意味着该小区 0上至少承载第二参考信号， 该第二参考信号为 DRS , CRS , RCRS , PS S , SS S和 CSI-RS 中的至少一种， 而小区 2是休眠态， 即小区 2 上承载 DRS或只承载 DRS , 那么在第二资源上的发送功率为 0 , 因 为第二资源不同于 DRS被发送的第一资源， 因此， 上述测量得到的 RSSI中就不包括小区 2的功率， 即休眠态小区的功率不会被计算在 被测小区的 RS SI中。
最后， UE 在测量出 RSRP 和 RSSI 之后， 便可根据 RSRP 和 RSSI的比值， 即 RSRP除以 RSSI , 来进一步确定 RSRQ或 SINR。 此时， 由于小区 0处于激活态， 因此， 小区 0在第二资源上的发送 功率不为 0 , 即第二资源上发送的 RCRS 的功率不为 0 , 此时， UE 根据 RSRP和 RS SI计算出 RSRQ。
本发明的实施例提供的无线资源管理的测量方法， 通过第一资 源上承载的第一参考信号的接收功率所确定的目标小区的参考信号 接收功率 RSRP , 以及第二资源上的总接收功率所确定的目标小区的 接收信号强度指示 RS SI , 来确定目 标小区的参考信号接收质量 RSRQ , 相比于现有技术中只根据 CRS 或 DRS 来测量目标小区的 RSRQ或 SINR , 并会导致一个区域内相邻小区间的干扰环境发生较 快的变化或抖动， 本发明所提供的无线资源管理的测量方法则效率 更高。 此外， 针对现有技术中 UE测量出的 RSRQ或 SINR会被低估 的问题， 本发明提供的第一资源与第二资源存在时刻差， 使得目标 小区的 RS SI 中并没有包含处于休眠态小区 （ 目标小区， 和 /或该目 标小区的邻区 ） 的功率， 从而避免上述 RSRQ被低估， 进而提高了 无线资源管理测量的正确率。 在第二种应用场景下 （即目标小区为激活态， 同时该目标小区 的 DRS与 RCRS处于相同子帧 ）：
首先， UE根据预先获取的 DRS的配置信息检测到小区 0后， UE确定该小区 0的 DRS所在的第一资源，即图 3所示的 4个 OFDM 符号上的总共 16个 RE ,然后测量该 16个 RE上的 DRS的平均接收 功率， 并将该平均接收功率作为该小区 0的 RSRP。 当然， UE可以 测量更多的 DRS子帧， 从而根据更多的 DRS的 RE来测量 RSRP , 测量用 RE越多， 测量得到的 RSRP越准确， 这里并不做限制。 此外， 还需要注意的是，小区 0的 DRS所在的 16个 RE上可能还会包括其 他小区在相同资源上发来的干扰信息和噪声， 但这里只需要测量该 16个 RE上所包含的该小区 0的 DRS的平均接收功率， 不将上述干 扰功率和噪声功率计算在 RSRP之内。
然后， 根据预设的第一资源与第二资源之间的资源偏移量， 及 第一资源在子帧资源块中的位置来确定第二资源， 由于小区 0 处于 激活态， 则该第二资源为 RCRS所在 OFDM符号上的所有资源。 如 图 4所示， 可以看到第二资源和第一资源在相同的子帧内， 即 DRS 发送在 RCRS子帧，且 DRS和 RCRS之间存在固定的 OFDM符号间 的位置关系， 那么 UE确定了 DRS所在符号， 进而便可确定第二资 源的 OFDM符号， 即 RCRS所在符号。 而 UE 在确定了第二资源的 位置后， 便测量该 RCRS所在 OFDM符号上的总接收功率， 该总接 收功率包括该 OFDM符号上的所有信号的接收功率， 并把该上述的 接收功率在多个 OFDM符号上取平均值作为该小区 0的 RS SI , 当然 也可以不做平均， 这里不做限制。
如图 4所示， 被测小区小区 0是激活态， 激活态意味着该小区 0上至少承载第二参考信号， 该第二参考信号为 DRS , CRS , RCRS , PS S , SS S和 CSI-RS 中的至少一种， 而小区 2是休眠态， 即小区 2 上承载 DRS或只承载 DRS , 那么在第二资源上的发送功率为 0 , 因 为第二资源不同于 DRS被发送的第一资源， 因此， 上述测量得到的 RSSI中就不包括小区 2的功率， 即休眠态小区的功率不会被计算在 被测小区的 RS SI中。 最后， UE 在测量出 RSRP 和 RSSI 之后， 便可根据 RSRP 和 RSSI的比值， 即 RSRP除以 RSSI , 来进一步确定 RSRQ或 SINR。 此时， 由于小区 0处于激活态， 因此， 小区 0在第二资源上的发送 功率不为 0 , 即第二资源上发送的 RCRS 的功率不为 0 , 此时， UE 根据 RSRP和 RS SI计算出 RSRQ。
本发明的实施例提供的无线资源管理的测量方法， 通过第一资 源上承载的第一参考信号的接收功率所确定的目标小区的参考信号 接收功率 RSRP , 以及第二资源上的总接收功率所确定的目标小区的 接收信号强度指示 RS SI , 来确定目 标小区的参考信号接收质量 RSRQ , 相比于现有技术中只根据 CRS 或 DRS 来测量目标小区的 RSRQ或 SINR , 并会导致一个区域内相邻小区间的干扰环境发生较 快的变化或抖动， 本发明所提供的无线资源管理的测量方法 H 'j效率 更高。 此外， 针对现有技术中 UE测量出的 RSRQ或 SINR会被低估 的问题， 本发明提供的第一资源与第二资源存在时刻差， 使得目标 小区的 RS SI 中并没有包含处于休眠态小区 （ 目标小区， 和 /或该目 标小区的邻区 ） 的功率， 从而避免上述 RSRQ被低估， 进而提高了 无线资源管理测量的正确率。 在第三种应用场景下 （即目标小区为休眠态， 同时该目标小区 的 DRS与 RCRS处于不同子帧 ）：
首先， UE根据预先获取的 DRS的配置信息检测到小区 0后， UE确定该小区 0的 DRS所在的第一资源，即图 5所示的 4个 OFDM 符号上的总共 16个 RE ,然后测量该 16个 RE上的 DRS的平均接收 功率， 并将该平均接收功率作为该小区 0的 RSRP。 当然， UE可以 测量更多的 DRS子帧， 从而根据更多的 DRS的 RE来测量 RSRP , 测量用 RE越多， 测量得到的 RSRP越准确， 这里并不做限制。 此外， 还需要注意的是，小区 0的 DRS所在的 16个 RE上可能还会包括其 他小区在相同资源上发来的干扰信息和噪声， 但这里只需要测量 16 个 RE上所包含的该小区 0的 DRS的平均接收功率， 不讲上述干扰 功率和噪声功率计算在 RSRP之内。
然后， 根据预设的第一资源与第二资源之间的资源偏移量， 及 第一资源在子帧资源块中的位置来确定第二资源。 需要说明的是， 虽然该小区 0 由于处于休眠态而并未发送 RCRS , 但是用于承载该 RCRS的第二资源还是实际存在的， 只是其中并未承载该 RCRS , 因 此， UE还是可以根据第一资源的位置及预设的第一资源与第二资源 之间的资源偏移量来获取该第二资源的位置。 UE在确定了第二资源 后， 此时， 由于被测小区小区 0及邻小区小区 2均处于休眠态， 因 此， 小区 0及小区 2的接收功率均未被计算在小区 0的 RSSI中， 则 该小区 0的 RS SI中只包含了邻小区小区 1 的接收功率。
最后， UE 在测量出 RSRP 和 RSSI 之后， 便可根据 RSRP 和 RSSI的比值， 即 RSRP除以 RSSI , 来进一步确定 RSRQ或 SINR。 此时， 由于小区 0处于休眠态， 因此， 小区 0在第二资源上的发送 功率为 0 , 即第二资源上并未发送 RCRS , 当然也不发送其他上述的 第二参考信息， 此时， UE根据 RSRP和 RS SI计算出 SINR。
本发明的实施例提供的无线资源管理的测量方法， 通过第一资 源上承载的第一参考信号的接收功率所确定的目标小区的参考信号 接收功率 RSRP , 以及第二资源上的总接收功率所确定的目标小区的 接收信号强度指示 RS SI , 来确定目 标小区的参考信号接收质量 RSRQ 和 /或信号与干扰加噪声比 SINR , 相比于现有技术中只根据 CRS或 DRS 来测量目标小区的 SINR , 并会导致一个区域内相邻小 区间的干扰环境发生较快的变化或抖动， 本发明所提供的无线资源 管理的测量方法则效率更高。 此外， 针对现有技术中 UE 测量出的 RSRQ或 SINR会被低估的问题， 本发明提供的第一资源与第二资源 存在时刻差， 使得目标小区的 RS SI 中并没有包含处于休眠态小区 ( 目标小区， 和 /或该目标小区的邻区 ）的功率， 从而避免上述 SINR 被低估， 进而提高了无线资源管理测量的正确率。 本发明的实施例提供的一种用户设备， 该用户设备用于实现上 述无线资源管理的测量方法， 如图 6所示， 该用户设备 3 包括： 确 定单元 3 1、 第一功率确定单元 32、 第二功率确定单元 33 和第三功 率确定单元 34 , 其中：
