下面结合附图对本申请实施例技术方案的主要实现原理、具体实施方式及其对应能够 达到的有益效果进行详细的阐述。
实施例一
请参考图 1 , 本实施例提供一种测量反馈的方法, 该方法包括:
S101 : 终端基于单小区参考信号进行测量, 以及基于多播广播单频网络参考信号进行 测量, 其中, 所述基于单小区参考信号进行测量和所述基于多播广播单频网络参考信号进 行测量是相关的;
S102: 所述终端根据单小区测量结果和多播测量结果进行上报, 其中, 所述单小区测 量结果为所述终端基于所述单小区参考信号进行测量得到的测量结果, 所述多播测量结果 为所述终端基于所述多播广播单频网络参考信号进行测量得到的测量结果
其中,单小区参考信号可以为小区专属参考信号( Cell-Specific Reference Signal, CRS )、 信道状态信息参考信号 ( Channel State Information-Reference Signal, CSI-RS ) 、 缩减的小 区专属参考信号 (Reduced Cell-Specific Reference Signal, RCRS )等, 本发明不限制进行 单小区测量的小区参考信号的类型。 下面以 CRS作为单小区参考信号为例, 对本发明的测 量反馈进行详细描述, 对于使用 CRS的情况都可以使用其他任何单 、区参考信号代替。 为 了描述简便, 下面将基于单小区参考信号进行测量称之为单小区测量、 基于多播广播单频 网络参考信号进行测量称之为多播测量。
在具体实施过程中, 网络可以釆用单小区向终端 (User Equipment, UE )发送数据, 也可以釆用多媒体广播多播业务( Multimedia Broadcast Multicast Service, MBMS )通过多 个小区釆用单频网络( Single Frequency Network , SFN )向终端发送数据。 基站在釆用单 小区传输数据时会向终端发送小区专属参考信号 CRS。 相应的, 基站釆用 MBMS传输数据
时会向终端发送多播广播单频网络参考信号 ( Multicast Broadcast Single Frequency Network Reference Signal, MBSFN RS ) 。 因此终端执行 S101基于 CRS和 MBSFN RS进行小区覆盖 情况测量。
在 S101中, 终端基于多播广播单频网络参考信号进行多播测量获得多播测量结果, 其 中多播测量结果包含 MBSFN RS的参考信号接收功率 (Reference Signal Received Power, RSRP )和多播广播单频网络 ( Multicast Broadcast Single Frequency Network, MBSFN ) 的 接收信号强度指示 ( Received Signal Strength Indicator , RSSI ) , 并可以才艮据公式 M*MRSRP/MRSSI来确定参考信号接收质量 ( MBSFN Reference Signal Received Quality, MRSRQ ) , 其中用 MRSRP表示 MBSFN RS的参考信号接收功率、 MRSSI表示 MBSFN的接 收信号强度指示、 M表示 MBSFN区域中用于测量 MRSSI的资源块个数。 在同一个载波上, 无线网络包括多个小区, 其中, 一个多播广播单频网络区域 (MBSFN area)包括一个或多个 小区, 还有其他小区是不包括在多播广播单频网络区域中。 终端在接收 MBSFN area的信号 时也会接收到该区域外其他单小区的干扰信号如 CRS, 因此终端基于小区专属参考信号进 行单小区测量获得单小区测量结果, 其中单小区测量结果包含单小区参考信号的参考信号 接收功率,用 RSRP表示单小区参考信号的参考信号接收功率(此处基于小区专属参考信号 进行 CRS测量) , 从而能够确定该单小区的信号对该 MBSFN area传输的信号的干扰程度。
终端在执行 S101获得单小区测量结果和多播测量结果之后, 执行 S102: 根据单小区测 量结果和多播测量结果进行上报。 具体的, 测量上报可以为直接上报单小区测量结果和多 播测量结果, 也可以上报根据单小区测量结果和多播测量结果计算后得到的结果和多播测 量结果。 终端的上述测量上报, 使得网络控制节点可以从基站获得与测量结果相关的上报 信息并根据终端的上报信息快速地调整为终端服务的小区或调整 MBSFN区域的组成,具体 可以根据 MRSRP和 MRSSI获得多播广播单频网络中的参考信号接收质量 MRSRQ, 并基于 MRSRQ和 RSRP进行调整。 例如, 在 RSRP较大, 对多播广播单频网络造成较大的干扰, 而 此时多播广播单频网络中的参考信号接收质量较低, 那么基站则可以考虑将干扰较强的单 小区添加到多播广播单频网络中, 从而增强多播广播单频网络的信号功率和信号质量; 相 反的, 在 RSRP非常小, 对多播广播单频网络干扰非常小, 而此时多播广播单频网络中的参 考信号接收质量很高, 那么基站则可以考虑从多播广播单频网络中去掉一个小区, 去除掉 的小区可以用于单小区数据传输, 从而增加单小区数据传输的资源, 有利于整个网络性能 的提高和单小区数据传输的吞吐量的增加。
可见, 本发明终端在进行上报时, 不仅进行多播测量还进行单小区测量, 并基于单小 区测量结果和多播测量结果向基站上报, 上报的信息不仅包含单小区的测量情况还包含多 播广播单频网络的测量情况, 能够更准确的反应测量区域的网络覆盖情况。 基站进一步可 以将终端上报的相关信息传输到网络控制节点, 使得网络控制节点能够获得单小区测量和
多播测量的测量结果的相关信息, 从而根据测量结果的相关信息快速地对多媒体广播多播 业务的小区组成进行优化, 进一步解决网络控制节点优化多媒体广播多播业务的小区组成 速率慢的技术问题, 提高多媒体广播多播业务的服务质量。 其中网络控制节点可以为移动 管理实体( Mobility Management Entity, MME )、多小区 /多播协调实体( Multi-cell/multicast Coordination Entity, MCE )等节点。
需要说明的是, UE的测量可以根据预定义的或基站配置的测量配置信息进行; UE的 上报也可以根据预定义的或基站配置的上报配置信息进行。 其中, 测量配置信息包括以下 信息: 进行单小区测量的小区标识和进行多播测量的 MBSFN区域标识。还可以包括测量时 间和 /或测量地理区域信息, 这里不排除还包括其他信息。 上报配置信息则包括上报周期和 /或上报触发条件, 这里不排除还包括其他信息。
在具体实施过程中, 终端进行单小区测量与进行多播测量是相关的测量, 进而保证单 小区测量结果和多播测量结果相互之间具有参考性。 具体的, 进行单小区测量的第一测量 时间窗和进行多播测量的第二测量时间窗相关;和 /或进行单小区测量的第一测量区域和进 行多播测量的第二测量区域相关;和 /或进行单小区测量的第一测量频段和进行多播测量的 第二测量频段相关。
当进行单 、区测量的第一测量时间窗和进行多播测量的第二测量时间窗相关时, 终端 通过接收基站下发的测量配置信息, 从接收到的测量配置信息中获得进行单 ' j、区测量和多 播测量的相关测量时间窗, 或者终端根据设备预定义的相关测量时间窗进行单小区测量和 多播测量。 具体的, 终端进行单小区测量的第一时间窗与进行多播测量的第二时间窗之间 的间隔小于时间阈值, 即第一时间窗的结束时刻与第二时间窗的开始时刻之间间隔小于时 间阈值, 或者第二时间窗的结束时刻与第一时间窗的开始时刻之间间隔小于时间阈值; 终 端也可以在开始进行单小区测量或多播测量后, 单小区测量或多播测量未完成之前进行另 一项测量, 即第一时间窗和第二时间窗部分重叠; 当然, 终端还可以在同一时间窗同时进 行单小区测量和多播测量, 即第一时间窗和第二时间窗全部重叠。
例如: 在某一测量时间周期内, 第一时间窗为 9: 00: 00-9: 00: 10, 终端在 9: 00: 00-9: 00: 10这段时间进行单小区测量。 若第二时间窗与第一时间窗之间的将小于第一时 间阈值如 5s, 那么进行多播测量的第二时间窗从 9: 00: 10-9: 00: 15之间的任一时刻开始 或者第二时间窗在 8: 59: 55-9: 00: 00之间的任一时刻结束; 若第二时间窗与第一时间 窗部分重叠, 那么终端进行多播测量的第二时间窗从 9: 00: 00-9: 00: 10之间的任一时 刻开始或者第二时间窗在 9: 00: 00-9: 00: 10之间的任一时刻结束; 若第二时间窗与第 一时间窗全部重叠, 那么终端则在 9: 00: 00-9: 00: 10进程单小区测量的同时进行多播 测量。
终端在进行单小区测量和多播测量时, 除了从测量时间上保证测量得到的单小区测量
结果和多播测量结果的相关性, 还可以从测量区域上来保证单小区测量结果和多播测量结 果的相关性。 当进行所述单小区测量的第一测量区域和进行所述多播测量的第二测量区域 相关时, 终端可以从基站下发的测量配置信息中或设备预定义信息中获得进行单小区测量 和进行多播测量的相关测量区域。 具体的, 终端进行单小区测量的第一测量区域和进行多 播测量的第二测量区域部分或全部重叠, 或者第一测量区域和第二测量区域的距离小于距 离阈值。 具体的, 第一测量区域和第二测量区域可以是终端所处的地理位置区域, 也可以 是终端所处的小区位置区域。 例如: 终端进行单小区测量的第一地理位置区域可以和终端 进行多播测量的第二地理位置区域相同或在距离阈值(如 10米) 范围内。
终端在进行单 、区测量和多播测量时,除了从测量时间和 /或测量区域上保证测量得到 的单小区测量结果和多播测量结果的相关性, 还可以从测量频段上来保证单小区测量结果 和多播测量结果的相关性。 当进行所述单小区测量的第一测量频段和进行所述多播测量的 第二测量频段相关时, 终端可以从基站下发的测量配置信息中或设备预定义信息中获得进 行单小区测量和进行多播测量的相关测量频段。 具体的, 终端进行单小区测量的第一测量 频段和进行多播测量的第二测量频段部分或全部重叠, 或者第一测量频段和第二测量频段 之间的间隔小于频段阈值。 例如: 终端进行单小区测量的第一测量频段和终端进行多播测 量的第二测量频段相同或相互之间的间隔小于频段阈值(如 720kHz或 N个物理资源块) 。
当然, 终端进行单小区测量和多播测量时不仅测量时间窗满足上述时间要求, 其测量 区域和 /或测量频段也同时满足上述要求,则能更进一步的保证单小区测量结果和多播测量 结果之间在时间与区域和 /频段上的相互参考性。
在具体实施过程中, 终端可以从基站下发的测量配置信息中获取具体针对哪一个小区 进行单小区测量, 从基站下发的上报配置信息中获取上报信息需要包含的内容。 该测量配 置信息和上报配置信息可以是基站根据实际需要即时向终端下发的, 也可以是基站在某一 周期内向终端下发的。 而本发明不限制基站向终端下发测量配置信息和上报配置信息的方 式, 可以是通过广播信令下发, 如通过系统信息块类型 2 ( SystemInformationBlockType2, SIB2 ) 、 系统信息块类型 13 ( SystemInformationBlockTypel3 , SIB13 ) 、 多播控制信道 (Multicast Control Channel, MCCH)、 MBMS等来下发,也可以是通过终端专属信令来下发。 例如: 基站通过终端专属信令向终端下发测量配置信息和上报配置信息, 测量配置信息中 要求终端对单小区 A和 MBSFN进行测量, 那么终端则根据测量配置信息, 对单小区 A进行 单小区测量、 对 MBSFN进行多播测量, 并根据上报配置信息将单 、区 A和 MBSFN的测量 结果按照预定的上报方式向基站上报。
在具体实施过程中, 终端进行单小区测量和多播测量得到测量结果之后, 可以直接向 基站上报, 也可以在接收到基站发送的上报要求时上报, 还可以由终端对测量结果进行进 一步判断, 在判断出单小区测量结果和多播测量结果满足上报触发条件时向基站上报。 终
端对测量结果进行进一步判断之后, 在满足上报触发条件时基于测量结果向基站上报, 可 以减少无效测量信息的上报, 节约电能并减小基站的负担。
其中, 上报触发条件可以由基站配置也可以是预定义的, 且上报触发条件可以为一个 触发条件或多个触发条件的组合。 具体的, 上报触发条件可以包含以下至少一个条件:
(1)、 终端得到的单小区测量结果和多播测量结果中多播广播单频网络参考信号的参考 信号接收功率与单小区参考信号的参考信号接收功率的比值小于第一阈值, 即 MRSRP/RSRP小于第一阈值, 表明单小区的信号对 MBSFN区域的干扰较强, 可能需要添 加一个小区到 MBSFN区域中以增强 MBSFN区域的信号接收功率和信号接收质量, 因此 终端需要基于单小区测量结果和多播测量结果向基站进行测量。
(2)、 终端得到的单小区测量结果和多播测量结果中多播广播单频网络参考信号的参考 信号接收功率与单小区参考信号的参考信号接收功率的比值大于第二阈值, 其中第二设定 阈值大于第一设定阈值, 即 MRSRP/RSRP大于第二阈值,表明单小区的信号对 MBSFN区 域的干扰很小, MBSFN 区域可能存在过度覆盖, 基站可以从 MBSFN 区域中去掉一个小 区, 使去掉的小区用于单小区数据传输, 以增强单小区数据传输的吞吐量, 因此终端需要 基于单小区测量结果和多播测量结果向基站进行上报。
(3)、多播广播单频网络中添加被测量的单小区后的第一参考值大于第三阈值或小于第 四阈值,即 MBSFN区域中添加被测量的单小区后的 MRSRQ大于第三阈值或小于第四阈值, 其中所述第四阈值大于所述第三阈值, 表明基站可能需要对 MBSFN的小区组成进行调整, 因此终端需要基于单小区测量结果和多播测量结果向基站进行上报。 本触发条件中添加被 测量的单小区后的 MRSRQ的具体算法在后续上报计算中进行详细说明。
(4)、 多播广播单频网络中去掉被测量的单小区后的第二参考值大于第五阈值或小于第 六阈值,即 MBSFN区域中去掉被测量的单小区后的 MRSRQ大于第五阈值或小于第六阈值, 其中所述第六阈值大于所述第五阈值,此时也表明基站可能需要对 MBSFN的小区组成进行 调整, 因此终端需要基于单小区测量结果和多播测量结果向基站进行上报。 本触发条件中 去除被测量的单小区后的 MRSRQ的具体算法在后续上报计算中进行详细说明。
(5)、 终端获得的单小区测量结果和多播测量结果中单小区参考信号的参考信号接收功 率 RSRP大于第七阈值, 表明单小区的信号接收功率过强, 可能会对 MBSFN区域的数据 传输造成较强的干扰, 基站可能需要添加一个小区到 MBSFN区域中以增强 MBSFN区域 的信号接收功率和信号接收质量, 因此终端需要基于单小区测量结果和多播测量结果向基 站进行上报。
(6)、 终端获得的单小区测量结果和多播测量结果中单小区参考信号的参考信号接收功 率 RSRP小于第八阈值,其中第八阈值小于第七阈值,表明终端接收到单小区信号接收功率 足够小, MBSFN区域可能存在过度覆盖, 基站可以从 MBSFN区域中去掉一个小区, 使去
掉的小区用于单小区数据传输, 以增强单小区数据传输的吞吐量, 因此终端需要基于单小 区测量结果和多播测量结果向基站进行上报。
(7)、终端获得的单小区测量结果和多播测量结果中多播广播单频网络 MBSFN的参考信 号接收功率 MRSRP的 M倍比上 MBSFN的接收信号强度指示 MRSSI小于第九阈值, 即 MBSFN的参考信号接收功质量 MRSRQ=M*MRSRP/MRSSI小于第九阈值。 此时, 表明 MBSFN区域的信号接收质量过小, 需要基站对 MBSFN包含的小区进行相应的调整, 因此 终端需要基于单小区测量结果和多播测量结果向基站进行上报。
(8)、 终端获得的单小区测量结果和多播测量结果中 MBSFN的参考信号接收功率 MRSRP的 M倍比上 MBSFN的接收信号强度指示 MRSSI大于第十阈值, 即 MRSRQ=M*MRSRP/MRSSI大于第十阈值,其中第十阈值小于第九阈值。此时,表明 MBSFN 区域的信号接收质量很好,基站可以考虑从 MBSFN中去掉一个小区, 因此终端需要基于单 小区测量结果和多播测量结果向基站进行上报。
终端无论是直接上报、 收到基站上报请求上报, 还是在测量结果满足上报触发条件时 基于单小区测量结果和多播测量结果进行上报的上报信息可以为单小区测量结果和多播 测量结果, 也可以为基于单小区测量结果和多播测量结果进行计算后的结果和多播测量结 果。 具体的, 上报信息可以包含: 单小区测量得到的单小区测量结果、 第一参考信息、 第 二参考信息中的至少一个信息及多播测量得到的多播测量结果, 其中, 所述第一参考信息 由所述终端根据所述单小区测量结果和所述多播测量结果计算获得; 所述第二参考信息由 所述终端根据所述单小区测量结果、 所述多播测量结果及所述单小区参考信号对应小区的 资源利用率计算获得。 下面对上报信息的具体内容进行举例说明:
第一种: 终端将进行单小区测量得到的单小区测量结果和进行多播测量得到的多播测 量结果上报基站, 如将 RSRP、 MRSRP, MRSRQ—起上报给基站。
第二种: 终端根据进行单小区测量得到的单小区测量结果和进行多播测量得到的多播 测量结果计算获得第一参考信息, 将第一参考信息、 单小区测量结果及多播测量结果上报 获得第一参考信息, 其中, MRSRP表示所述多播广播单频网络参考信号的参考信号接收 功率; MRSSI表示 MBSFN区域中接收信号强度指示; RSRP表示小区专属参考信号的参 考信号接收功率; M 为正整数, 具体可以为 MBSFN 区域中用于测量 MRSSI 的资源块 ( Resource Block, RB )个数。 终端可以根据基站测量配置信息或终端预定义信息来选择 M*(MRSRP+RSRP)/MRSSI 或 M*(MRSRP-RSRP)/MRSSI 获得第一参考信息。 通过公式 M*(MRSRP+RSRP)/MRSSI获得第一参考信息可以得到 MBSFN区域中添加被测量的单小 区之后 MBSFN 区域的参考信号接收质量 MRSRQ; 相反的 , 通过公式 M*(MRSRP-RSRP)/MRSSI可以获得 MBSFN区域中去掉被测量的单小区之后 MBSFN区
域的参考信号接收质量 MRSRQ。 由于终端经过计算获得添加单小区或却掉单小区之后 MBSFN区域的 MRSRQ即第一参考信息, 并将计算获得的第一参考信息上报基站, 减少 基站在接收到 RSRP、 MRSRP及 MRSSI后进行计算获得第一参考信息而产生的量化误差, 从而提高上报的准确性。
第三种: 终端根据进行单小区测量得到的单小区测量结果、进行多播测量得到的多播 测量结果及小区专属参考信号对应小区的资源利用率计算获得第二参考信息, 将第二参考 信息、 单小区测量结果及多播测量结果上报基站。 具体的, 终端可以根据公式 M*(MRSRP+RSRP*alfa)/MRSSI或 M*(MRSRP-RSRP*alfa)/MRSSI获得第二参考信息, 其 中, MRSRP表示所述多播广播单频网络参考信号的参考信号接收功率; MRSSI表示所述接 收信号强度指示; RSRP表示所述小区专属参考信号的参考信号接收功率; alfa表示所述小 区专属参考信号对应小区的资源利用率, alfa为预定义的或基站配置的, alfa大于 0小于 1 , M为正整数, 具体可以为 MBSFN区域中用于测量 MRSSI的资源块个数。 终端可以根据基站 测量配置信 息或终端预定义信 息来选择 M*(MRSRP+RSRP*alfa)/MRSSI或 M*(MRSRP-RSRP*alfa)/MRSSI 获 得 第 二 参 考 信 息 。 通 过 公 式 M*(MRSRP+RSRP*alfa)/MRSSI获得第二参考信息可以得到 MBSFN区域中添加被测量的 单小区之后 MBSFN区域的 MRSRQ; 相反的, 通过公式 M*(MRSRP-RSRP*alfa)/MRSSI可以 获得 MBSFN区域中去掉被测量的单小区之后 MBSFN区域的 MRSRQ。终端通过上述两个公 式计算获得的第一参考信息上报基站, 不仅能够减少量化误差、 提高上报的准确性, 还由 于终端在添加或去除单小区的计算中还考虑了 CRS对应单小区的资源利用率, 进一步增强 了小区调整后 MBSFN区域的 MRSRQ的准确性。
在具体实施过程中, 除上述三种上报信息, 上报信息还可以为多播测量结果和第一参 考信息; 多播测量结果和第二参考信息; 多播测量结果、 第一参考信息及第二参考信息等, 根据本发明上述示例能够清楚的获知上报数据的具体内容组合, 在此不再——例举。 无论 上报数据包含上述哪些信息均可以釆用联合上报的方式向基站上报, 其中联合上报用于指 示上报的参数之间是相关的, 若终端将所述单小区测量结果和所述多播测量结果进行联合 上报, 表明所述单小区测量结果和所述多播测量结果为相关测量结果; 若终端根据所述单 小区测量结果和所述多播测量结果计算获得参考结果, 将所述参考结果、 所述单小区测量 结果及所述多播测量结果进行联合上报, 表明所述联合上报用于指示所述参考结果、 所述 单小区测量结果及所述多播测量结果为相关测量结果。 具体的, 联合上报可以釆用普通编 码方式向基站上报, 如分别对 RSRP、 MRSRP ^ MRSRQ进行编码, 然后将编码后的结果置 于一个上报数据包中上报给基站; 当然, 也可以釆用联合编码方式向基站上报, 联合编码 能够降低上报需要的总开销, 且能够有效表示上报的单小区测量结果和多播测量结果之间 是相关的。 另外, 终端基于单小区测量和多播测量结果获得的测量结果向基站上报时, 还
可以上报进行单小区测量和进行多播测量的测量时间信息; 和 /或测量区域信息; 和 /或测 量频段信息。 其中, 测量时间信息用于指示进行单小区测量的测量时间窗和进行多播测量 的测量时间窗具有相关性; 测量区域信息用于指示进行单小区测量的测量区域和进行多播 测量的测量区域具有相关性; 测量频段信息用于指示进行单小区测量的测量频段和进行多 播测量的测量频段具有相关性。 具体的, 测量区域信息可以为进行单小区测量和多播测量 的地理位置信息, 也可以为进行单 d、区测量和多播测量的小区区域信息。从测量时间 /测量 区域 /测量频段来说明上报的单小区测量结果和多播测量结果之间是相关的。
终端也可以通过各种其他指示单小区测量结果和多播测量结果之间相关性的方式来 上报测量结果, 如在上报信息中增加相关指示标识或按照指定的编码方式编码上报信息 等, 本发明不限定指示单小区测量结果和多播测量结果之间相关性的方式。
当终端通过任一方式指示单小区测量结果和多播测量结果之间的相关性,并根据测量 结果上报时, 网络控制节点可以根据上报的相关信息有效判断是否需要增加一个小区到 MBSFN区域或从 MBSFN区域中去掉一个小区。
在具体实施过程中, 为了使终端测量多播广播单频网络的接收信号强度指示时更准 确, 本发明还根据多播广播单频网络传输的子帧中的至少一个指定符号测量获得接收信号 强度指示, 其中, 指定符号为所述子帧数据区域中的符号。 由于终端不是根据 MBSFN传输 的子帧中的所有符号来测量获得 MRSSI, 而是排除了与信号接收强度相关性低的控制区域 的符号,根据数据区域中的符号来测量获得 MRSSI,从而使得测量获得的 MRSSI更为准确。
在 MBSFN传输的子帧中,用于测量 MRSSI的指定符号可以是数据区域中所有的符号, 如使用扩展循环前缀( Cyclic Prefix, CP ) 包含 12个符号的子帧, 当控制区域的符号为 1个 时, 选择数据区域编号为 1~11的所有符号为指定符号; 当控制区域的符号为 2个时, 则选 择数据区域编号为 2~11的所有符号为指定符号。
MBSFN传输的子帧在实际传输过程中, 由于单小区信号的干扰, 子帧中的部分符号 会承载有小区专属参考信号, 这些符号更能体现存在干扰的情况下真实的信号接收强度指 示 MRSSI, 因此用于测量 MRSSI的指定符号也可以是子帧数据区域中承载小区专属参考信 号的符号。 请参考图 2, 以单小区釆用常规 CP为例, 单小区传输的子帧在数据区域中编号 为 4/7/8/11的符号为承载有 CRS的符号, 那么 MBSFN传输的子帧则对应可能在编号为 4/7/8/11的符号上承载有 CRS , 因此选择编号为 4/7/8/11的符号作为指定符号用于 MRSSI的 测量。
此外, 承载小区专属参考信号的符号与 MBSFN子帧中用于承载多播业务和 /或多播广 播单频网络参考信号的符号交叠时, 也会影响 MRSSI, 因此用于测量 MRSSI的指定符号还 可以是数据区域中与承载所述小区专属参考信号的符号有交叠的用于承载多播业务和 /或 所述多播广播单频网络参考信号的符号。 以单小区釆用常规 CP为例, 请参考图 3, MBSFN
子帧的数据区域中承载有 MBSFN RS的编号为 6的符号与承载 CRS信号的符号有交叠;承载 多播业务的编号为 3/4/7的符号与承载 CRS信号的符号有交叠; 承载多播业务和 MBSFN RS 的编号为 9/10的符号与承载 CRS信号的符号有交叠, 那么则可以选择 3/4/6/7/9/10中至少一 个符号作为指定符号, 进行 MRSSI测量。
由于单小区信号中编号为 0~3的符号可能承载单小区的控制信号, 相应的, 在 MBSFN 的子帧中编号为 0~3的符号因受到单小区信号的干扰也有可能与承载单小区控制信号的符 号重叠或交叠, 而这些符号不利于 MBSFN区域相关的 MRSSI的测量, 因此在上述方法选择 的指定符号中进一步选择编号大于等于 4的符号作为测量 MRSSI的符号。 由于测量 MRSSI 的符号不会包括任何 MBSFN区域外单小区的控制信号,从而保证 MRSSI中包括的单小区干 扰中只有对应单小区的数据区域信号带来的干扰, 从而排除了单小区控制信号负载波动对 MBSFN区域调整和参数调整带来的影响,更准确地体现单小区业务传输对绝大多数 MBMS 业务符号带来的干扰情况,有利于网络控制节点根据这种干扰情况来更准确的调整 MBSFN 区域和 /或 MBMS业务传输参数。
本发明实施例中的上述一个或多个技术方案,通过终端基于单小区参考信号进行单小 区测量, 以及基于多播广播单频网络参考信号进行多播测量; 并根据单小区测量和多播测 量得到的测量结果进行上报, 实现基于单小区参考信号和多播广播单频网络参考信号的测 量上报。
实施例二
请参考图 4、 本发明实施例提供一种测量反馈方法, 所述方法包括:
S401:终端根据多播广播单频网络传输的子帧中的至少一个指定符号测量获得所述多 播广播单频网络的接收信号强度指示, 其中, 所述指定符号为所述子帧的数据区域中的符 号;
S402: 所述终端根据所述接收信号强度指示进行上报。
在具体实施过程中, 由于多播广播单频网络 MBSFN传输的子帧中包含控制区域和数 据区域, 其中控制区域的符号用于承载控制信号, 数据区域的符号用户承载多播业务和参 考信号 MBSFN RS。 为了使终端测量多播广播单频网络的接收信号强度指示时更准确, 终 端根据多播广播单频网络传输的子帧中的至少一个指定符号测量获得接收信号强度指示 MRSSI, 其中, 指定符号为所述子帧数据区域中的符号。 由于终端不是根据 MBSFN传输的 子帧中的所有符号来测量获得 MRSSI, 而是排除了与信号接收强度相关性低的控制区域的 符号, 根据数据区域中的符号来测量获得 MRSSI, 从而使得测量获得的 MRSSI更为准确。
在具体实施过程中, 在 MBSFN传输的子帧中, S401中用于测量 MRSSI的指定符号可 以是数据区域中所有的符号; 也可以是也可以是数据区域中承载小区专属参考信号的符 号; 还可以是数据区域中与承载所述小区专属参考信号的符号有交叠的承载多播业务和 /
或所述多播广播单频网络参考信号的符号。 当指定符号为数据区域中承载小区专属参考信 号的符号时, 或者当指定符号为数据区域中与承载所述小区专属参考信号的符号有交叠的 用于传输多播业务和 /或所述多播广播单频网络参考信号的符号时, S401测量获得信号接收 强度指示 MRSSI为存在单小区信号干扰的实际传输过程中多播广播单频网络真实的信号 接收强度反应, 进一步提高了测量获得的 MRSSI的准确性。 由于终端根据上述至少一个指 定符号获得多播广播单频网络的接收信号强度指示在实施例一中结合图 2和图 3已进行详 细说明, 所以为了说明书的简洁, 在此不再详述。
实际应用中, 由于单小区信号中编号为 0~3的符号可能承载单小区的控制信号, 相应 的, 在 MBSFN的子帧中编号为 0~3的符号因受到单小区信号的干扰也有可能与承载单小区 控制信号的符号重叠或交叠, 而这些符号不利于 MBSFN的 MRSSI的测量, 因此在上述方法 选择的指定符号中进一步选择编号大于等于 4的符号作为测量 MRSSI的符号。 由于测量 MRSSI的符号不会包括任何 MBSFN区域外单小区的控制信号,从而保证 MRSSI中包括的单 小区干扰中只有对应单小区的数据区域信号带来的干扰, 从而排除了单小区控制信号负载 波动对 MBSFN区域调整和参数调整带来的影响,更准确地体现单小区业务传输对绝大多数 MBMS业务符号带来的干扰情况, 有利于网络控制节点根据这种干扰情况来更准确的调整 MBSFN区域和 /或 MBMS业务传输参数。
在 S401中获得多播广播单频网络的接收信号强度指示 MRSSI后, 终端继续执行 S402: 所述终端根据所述接收信号强度指示进行上报。 具体的, 终端可以直接将接收信号强度指 示上报给基站, 也可以根据公式 M*MRSRP/MRSSI确定参考信号接收质量 MRSRQ, 然后 将信号接收信号强度指示和参考信号接收质量 MRSRQ上报给基站, 其中, MRSRP表示所 述多播广播单频网络参考信号的参考信号接收功率, 由终端进行 MRSSI测量时测量获得; M为正整数, 具体可以为多播广播单频网络 MBSFN中用于测量 MRSSI的资源块 ( Resource Block, RB )个数。 由于 S401中获得的了更为准确的 MRSSI, 因此根据该 MRSSI 确定并上报的 MRSRQ的准确性也相应的得到了提高。
