The averaging is performed until the terminal receives the status indicator indicating the second status again.
- the MBMS control channel and the MBMS scheduling channel adopt the same modulation and coding mode
- the MBMS data channel may adopt a modulation and coding manner different from the MBMS control channel and the MBMS scheduling channel, and therefore,
- the candidate measurement result of the first subframe that carries the MBMS control channel and the second subframe that carries the MBMS scheduling channel is averaged separately from the candidate measurement result of the third subframe that carries the MBMS data channel, that is, the first subframe

- an MBSFN area includes five base stations, and each base station covers one cell (Cell).
- the five base stations initially belong to the MBSFN area, and jointly provide MBMS services for the terminals in the MBSFN area.
- the terminal performs MBSFN reception quality measurement according to the measurement method of the foregoing reception quality, and transmits the obtained target measurement result to the network device. If the network device finds that the MBSFN reception quality is very good, the number of base stations participating in the MBMS service in the MBSFN area may be appropriately reduced, for example, the previous five base stations are reduced to three base stations, that is, the base station 4 and the cell in the cell 4 may be used.
- the base station 5 in 5 moves out of the MBSFN area, that is, the base station 4 and the base station 5 will no longer provide the MBMS service, but provide the unicast service.
- the terminal After the base station 4 and the base station 5 move out of the MBSFN area, the area identifier of the MBSFN area, the MBMS control channel, the MBMS scheduling channel, and the MBMS data channel do not change, that is, the change in the number of the base stations is transparent to the terminal, and the terminal does not Knowing the change in the number of base stations, the terminal will continue to measure the MBSFN reception quality and report the target measurement result to the network device.
- the MBSFN reception quality is different before and after the number of base stations changes. Therefore, if the terminal changes the number of the base stations. The average measurement of candidate measurement results before and after will result in inaccurate target measurement results.

【具体实施方式】
为了更好的理解本发明的技术方案,下面结合附图对本发明实施例进行详细描述。
应当明确,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作出创造性劳动前提下所获得的所有其它实施例,都属于本发明保护的范围。
本发明实施例给出一种接收质量的测量方法,请参考图1,其为本发明实施例所提供的接收质量的测量方法的流程示意图;如图1所示,该方法包括以下步骤:
步骤101,获得MBMS控制信道的至少一个变更时间窗组;每个所述变更时间窗组包括至少一个变更时间窗。
具体的,终端与网络同步后,可以接收网络设备广播的系统信息,所述网络设备可以包括:基站、MBMS控制单元、无线网络控制器(Radio
Network Controller,RNC)等;所述系统信息可以包括物理广播信道(Physical Broadcast
Channel,PBCH)和系统信息块,该系统信息块(System Information
Block,SIB)可以包括SIB1、SIB2和SIB13。终端从PBCH中可以获得系统无线帧号(System Frame
Number,SFN)。终端还可以继续读取SIB1,并依据SIB1中携带的SIB13的接收时间窗来读取SIB13,SIB13中包括MBMS控制信道的配置信息,所述MBMS控制信道的配置信息包括:MBMS控制信道的变更周期、MBMS控制信道的重复周期、无线帧偏移量和子帧标识等。一个MBSFN区域可以对应一个MBMS控制信道。
本发明实施例中,终端可以依据系统无线帧号和变更周期,获得所述MBMS控制信道的至少一个变更时间窗组,具体包括:首先,终端获得起始无线帧号;所述起始无线帧号为满足以下公式的系统无线帧号:系统无线帧号mod变更周期=0,即:所述系统无线帧号除以所述变更周期的余数等于0,也就是说,若某一系统无线帧号除以变更周期的余数等于0,那么该系统无线帧号可以作为起始无线帧号;然后,终端依据起始无线帧号之后连续的至少一个变更周期的时域长度,获得一个变更时间窗组;即:终端以该起始无线帧为起点,该起始无线帧之后连续的时域长度为一个变更周期的时域资源就是一个变更时间窗,连续的至少一个所述变更时间窗可以组成一个所述变更时间窗组。
其中,一个变更时间窗组中可以包括至少一个变更时间窗,一个变更时间窗组中变更时间窗的具体数目可以预先配置,还可以由网络设备通过信令发送给终端,例如,网络设备在系统信息中携带该一个变更时间窗组中变更时间窗的数目,或者网络设备通过MBMS控制信道向终端发送一个变更时间窗组中变更时间窗的数目。
其中,MBMS控制信道在一个变更周期内重复发送至少一次,重复发送的周期就是重复周期,例如,请参考图2,其为本发明实施例所提供的变更时间窗的示意图,如图所示,变更周期为512个系统无线帧,重复周期为128个系统无线帧,则一个变更周期内MBMS控制信道需要重复发送4次,整个变更周期内的时域资源就是一个变更时间窗。
步骤102,获得每个所述变更时间窗的至少一个子帧。
具体的,首先,终端依据所述系统无线帧号、所述重复周期和所述无线帧偏移量,获得变更时间窗内的承载MBMS控制信道的第一无线帧,第一无线帧为满足下述公式的系统无线帧:
系统无线帧号mod重复周期=无线帧偏移量
例如,如图2所示,无线帧偏移量为64,重复周期为128,
系统无线帧号mod128=64,则系统无线帧号可以为64、192、320和448,则第一无线帧是系统无线帧号为64、192、320和448的系统无线帧。
其次,终端依据所述子帧标识,在上述第一无线帧中确定承载MBMS控制信道的第一子帧;该子帧标识可以是子帧编号,该子帧标识用于指示第一无线帧中哪些子帧可以是第一子帧,例如,第一子帧可以是第一无线帧中的子帧1、子帧2、子帧3、子帧6、子帧7和子帧8。
优选的,终端在确定承载MBMS控制信道的第一子帧后,还可以进一步在该第一子帧上接收MBMS控制信道,并从MBMS控制信道中获得MBMS控制信道对应的MBSFN区域的候选MBMS子帧、MBMS调度信道的周期和MBMS数据信道的结束子帧指示,终端可以依据系统无线帧号和MBMS调度信道的周期,确定承载MBMS调度信道的第二无线帧,然后将第二无线帧中的第一个子帧作为第二子帧;例如,请参考图3,其为本发明实施例所提供的变更时间窗的子帧示意图,如图所示,可以将满足如下公式的系统无线帧作为第二无线帧:
系统无线帧号mod MBMS调度信道的周期=0
由于MBMS数据信道具有灵活性,不一定所有的候选MBMS子帧都用来承载MBMS数据信道,因此,可以通过MBMS数据信道的结束子帧指示,来指示终端候选MBMS子帧中实际承载MBMS数据信道的子帧,因此,终端可以依据MBMS数据信道的结束子帧指示,在候选MBMS子帧中确定承载MBMS数据信道的子帧,该子帧就是第三子帧。
步骤103,在每个所述子帧中进行MBSFN接收质量的测量,以获得候选测量结果。
具体的,若终端在步骤102中,获得第一子帧、第二子帧和第三子帧,则终端可以在上述第一子帧、第二子帧和第三子帧中的至少一个子帧中,每个子帧获得MBSFN
RS;依据所述MBSFN RS进行MBSFN区域的MBSFN接收质量的测量,以获得候选测量结果。其中,MBSFN
RS是利用MBSFN区域特有的区域标识进行加扰的,该区域标识也承载在上述SIB13中。
或者,若终端在步骤102中,只获得第一子帧,则终端只在第一子帧中进行MBSFN
接收质量的测量,而不在第二子帧和第三子帧中进行MBSFN
接收质量的测量,是因为第二子帧的子帧标识、第三子帧的子帧标识和第三子帧上MBMS数据信道的调制编码方式都是在获得MBMS控制信道之后才能得到,因此,只在承载MBMS控制信道的的第一子帧中进行MBSFN接收质量的测量,而不进一步获得第二子帧和第三子帧,可以简化MBSFN
接收质量的测量流程和终端实现复杂度。
其中,所述MBSFN接收质量包括以下信息中至少一个:
MBSFN参考信号接收功率(Reference Signal Receiving
Power,RSRP)、MBSFN参考信号接收质量(Reference Signal Receiving
Quality,RSRQ)、MBSFN接收信号强度指示(Received Signal Strength
Indication,RSSI)、MBSFN信道质量指示(Channel Quality
Indicator,CQI)、MBSFN信号与干扰加噪声比(Signal to Interference plus Noise
Ratio,SINR)、MBSFN块误码率(Block Error Ratio,BLER)和MBSFN误包数。
其中,MBSFN RSSI指的是在符号或子帧上全部接收功率,MBSFN RSRQ可以依据MBSFN
RSRP与MBSFN RSSI的比值获得,MBSFN SINR等于MBSFN RSRP除以MBSFN RSSI和MBSFN RSRP的差值或者MBSFN
SINR等于MBSFN RSRP,MBSFN CQI指的是在一定的MBSFN块误码率下的MBSFN
SINR或者调制编码方式,MBSFN误包数指的是一段时间内误包的数目。其中,终端可以通过MBSFN
BLER的测量,获得调制编码方式和该调制编码方式对应的块误码率,并存储调制编码方式和该调制编码方式对应的块误码率,还可以向网络设备上报该调制编码方式和该调制编码方式对应的块误码率。这样,不同的终端不用在相同的MBSFN
BLER的情况下测量得到调制编码方式,而是比较自由地依据自身测量得到的实际MBSFN BLER得到调制编码方式,使得终端测量的实现方式更为灵活。
步骤104,依据所述候选测量结果和每个所述变更时间窗,获得目标测量结果。
具体的,终端在每个所述子帧中进行MBSFN接收质量的测量后,可以依据获得的候选测量结果和每个变更时间窗,对候选测量结果进行平均计算,以获得目标测量结果,可以提高测量精度和稳定性。
本发明实施例中,终端依据所述候选测量结果和每个所述变更时间窗,获得目标测量结果的方法可以包括以下几种:
第一种:终端依据每个所述变更时间窗的至少一个子帧中获得的所述候选测量结果,获得每个所述变更时间窗的候选测量结果的平均值,所述候选测量结果的平均值为所述目标测量结果;即:终端只允许对属于同一个变更时间窗内的至少一个子帧上的候选测量结果进行平均计算,不可以对属于不同变更时间窗的子帧上的候选测量结果进行平均计算,这样,至少一个变更时间窗中的每个变更时间窗都对应获得一个目标测量结果。
第二种:如果所述变更时间窗组包括至少两个所述变更时间窗,则终端依据所述至少两个变更时间窗中每个所述变更时间窗的至少一个子帧中获得的所述候选测量结果,获得所述变更时间窗组的候选测量结果的平均值,所述候选测量结果的平均值为所述目标测量结果;即:终端只允许对属于同一变更时间窗组的至少一个子帧上的候选测量结果进行平均计算,不可以进行属于不同变更时间窗组的子帧上的候选测量结果的平均计算,这样,至少一个变更时间窗组中,每个变更时间窗组都对应获得一个目标测量结果。
第三种:如果所述至少一个变更时间窗组包括至少两个变更时间窗组,则终端获得状态标识;所述状态标识指示第一状态或第二状态,状态标识可以利用比特或者扰码等方式实现,例如,比特等于0时,状态标识指示第一状态,比特等于1时,状态标识指示第二状态。
若所述状态标识指示第一状态,则表示终端可以进行收到状态标识之后的变更时间窗的候选测量结果与之前的变更时间窗的候选测量结果的平均计算,即依据所述状态标识之前的至少一个所述变更时间窗的候选测量结果和所述状态标识之后的至少一个所述变更时间窗的候选测量结果,获得所述候选测量结果的平均值,所述候选测量结果的平均值为所述目标测量结果。
若所述状态标识指示第二状态,则表示终端不可以进行收到状态标识之后的变更时间窗的候选测量结果与之前的变更时间窗的候选测量结果的平均计算,即在收到指示第二状态的状态标识后,不可以依据所述状态标识之前的至少一个所述变更时间窗的候选测量结果和所述状态标识之后的至少一个所述变更时间窗的候选测量结果,获得所述候选测量结果的平均值,即不可以对获得状态标识前后的候选测量结果进行平均计算。
这里,如果终端一直没有收到指示第二状态的状态标识,则终端可以一直进行收到状态标识之后的变更时间窗的候选测量结果与之前的变更时间窗的候选测量结果的平均计算,一旦收到指示第二状态的状态标识,则终端就不可以进行后续的候选测量结果与之前的候选测量结果的平均计算,但是终端可以对收到指示第二状态的状态标识之后收到的候选测量结果进行平均计算,直到终端再次收到指示第二状态的状态标识时为止。
进一步的,对于上述三种方法,考虑到MBMS控制信道与MBMS调度信道采用相同的调制编码方式,而MBMS数据信道可以采用不同于MBMS控制信道与MBMS调度信道的调制编码方式,因此,还可以将承载MBMS控制信道的第一子帧和承载MBMS调度信道的第二子帧的候选测量结果,与承载MBMS数据信道的第三子帧的候选测量结果分开进行平均计算,即对第一子帧的候选测量结果与第二子帧的候选测量结果进行平均计算,对第三子帧的候选测量结果单独进行平均计算。
可选的,在进行了上述MBSFN接收质量的测量之后,得到至少一个子帧的候选测量结果或得到上述物理层的变更时间窗或变更时间窗组中候选测量结果的平均值后,还可以进一步将该平均值在高层(如无线资源控制(Radio
Resource Control,RRC)层或媒体访问控制(Media Access
Control,MAC)层)进行进一步的平均处理,此时还需要在高层引入平均时间窗以及平均时间窗组,该高层的平均时间窗或平均时间窗组可以大于或等于上述物理层的变更时间窗或变更时间窗组,即对上述高层的平均时间窗或平均时间窗组中对应的物理层的测量结果,进行进一步的平均处理,得到最终的测量结果,然后保存该最终的测量结果,还可以进一步向网络设备上报该最终的测量结果。
优选的,在步骤104之后,该方法还可以包括:
终端判断终端的状态;若所述终端的状态为空闲态,终端存储所述目标测量结果,待终端的状态为连接态时,终端可以向网络设备发送该目标测量结果;若所述终端的状态为连接态,终端向网络设备发送所述目标测量结果。
实施例
请参考图4,其为本发明实施例所提供的MBSFN区域中小区的示意图,如图所示,MBSFN区域包括5个基站,每个基站覆盖一个小区(Cell)。
5个基站最开始都属于该MBSFN区域,共同为该MBSFN区域内的终端提供MBMS业务,终端依据上述接收质量的测量方法进行MBSFN接收质量的测量,并将获得的目标测量结果发送给网络设备。如果网络设备发现MBSFN接收质量非常好,则可以适当减少该MBSFN区域内参与MBMS业务的基站的数量,例如将之前的5个基站减少为3个基站,即可以将小区4中的基站4和小区5中的基站5移出该MBSFN区域,即基站4和基站5将不再提供MBMS业务,而是提供单播业务。
基站4和基站5移出该MBSFN区域后,MBSFN区域的区域标识、MBMS控制信道、MBMS调度信道和MBMS数据信道等都不发生变化,即上述基站数量的变化对于终端而言是透明的,终端不知道上述基站数量的变化,因此终端会继续进行MBSFN接收质量的测量,并将目标测量结果上报给网络设备,因为基站数量改变前后,MBSFN接收质量存在差别,因此,如果终端将上述基站数量的变化前后的候选测量结果进行平均处理,将会导致目标测量结果的不准确。
为了解决基站数量变化前后目标测量结果不准确的问题,本发明实施例中提供了上述三种依据所述候选测量结果和每个所述变更时间窗,获得目标测量结果的方法,例如,对于其中的第三种方法,当基站数量发生变化前,网络设备向终端发送状态标识,指示终端不可以将状态标识之后变更时间窗的子帧的候选测量结果与之前变更时间窗的子帧的候选测量结果进行平均计算,这样,终端就不会将基站数量的变化前后的候选测量结果进行平均处理,从而可以避免基站数量改变后目标测量结果的不准确问题。
需要说明的是,即使只允许对一个变更时间窗内的子帧上的候选测量结果进行平均计算,也不会对目标测量结果的精度有较大影响,因为一个变更时间窗内的子帧数量比较多,因此还可以满足MBSFN接收质量测量的精度要求。
