本申请涉及通信领域,更具体地,涉及一种用于无线资源管理RRM测量的方法和装置。

但是,在新无线(new radio,NR)***中,由于网络设备覆盖范围比较小,例如,ISD=200,即使终端在覆盖边缘的部分地区可能性能仍然比较好。终端可能在这些区域随时进入其他小区,如果终端测量周期比较大,移动速度比较大,则RRM测量得到的测量结果不能够及时反应这种变化,导致接收信号质量差,进而会造成小区内的切换失败,从而使得终端的功耗开销较大。也就是说,传统方案中,终端只能采用增大RRM测量周期来调整RRM测量方式,该RRM测量方式的调整,仍然使得终端的开销较大。

201,网络设备确定RRM测量的测量条件。
需要说明的是,该测量条件可以看作制定的测量规则。
可选地,所述测量条件包括测量结果与信道质量阈值、参考信号索引、同步信号块索引或运动速度中的至少一项的关联关系。
具体地,网络设备可以为终端配置测量结果与信道质量阈值、参考信号索引、同步信号块索引或运动速度阈值中的至少一项存在关联关系的测量条件。也就是说,终端可以考虑多种参考因素,进行RRM测量调整。
可选地,所述测量条件具体可以包括测量结果与至少一个所述信道质量阈值的大小关系。
具体地,该测量条件可以是测量结果与至少一个信道质量阈值的大小关系。该信道质量阈值可以是一个,也可以是多个。
例如,在信道质量阈值为一个的情况下,该测量条件可以是大于第一质量阈值,或小于第一质量阈值。即大于第一质量阈值的情况下不可以进行RRM测量的松弛,小于第一质量阈值的情况可以进行RRM测量的松弛。或者大于第一质量阈值的情况下可以进行RRM测量的松弛,小于第一质量阈值的情况下不可以进行RRM测量的松弛。
又例如,在信道质量阈值为多个的情况下,该测量条件可以是测量结果大于第一质量阈值,且小于第二质量阈值。即大于第一质量阈值,且小于第二质量阈值的情况下,进行RRM测量的松弛。小于第一质量阈值或大于第二质量阈值的情况下,不进行RRM测量的松弛。
再例如,该测量条件可以是测量结果大于第一质量阈值或小于第二质量阈值。即大于第一质量阈值,且小于第二质量阈值的情况下,不可以进行RRM测量的松弛。小于第一质量阈值或大于第二质量阈值的情况下,可以进行RRM测量的松弛。
可选地,信道质量阈值可以是网络设备根据RSRP、RSRQ或SINR中的至少一项确定的。
具体地,该信道质量阈值可以网络设备从RSRP、RSRQ或SINR中的至少一项选出的。该阈值可以是基于一次样本的测量结果,也可以是基于K次样本的测量结果,K的值可以是固定的。例如,网络设备与终端约定的,或者协议规定的,也可以是网络设备配置的。K的取值可以是1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16中的任意一项。
需要说明的是,样本可以是对物理层参考信号进行处理得到的样本,也可以是经过物理层滤波后得到的样本,也可以是经过高层滤波(例如,L3-filter)后得到的样本。
可选地,该质量阈值可以是根据同频小区测量预设阈值(S-measure)确定的,或根据邻区测量预设阈值(criterion S)确定的。
具体地,在终端处于空闲态(idle)的情况下,该质量阈值可以是网络设备根据criterion S的阈值确定的。在终端处于连接态的情况下,该质量阈值可以是网络设备根据S-measure的阈值确定的。也就是说,在固定场景中,可以采用固定的值作为质量阈值,不需要网络设备专门指示该质量阈值,从而降低了信令开销。例如,终端在空闲态的情况下,该质量 阈值可以是Qrxlevmeas值+第一偏移值(offset1),或Qqualmeas值+第二偏移值(offset2)。
需要说明的是,该第一偏移值和第二偏移值分别可以是预先设定的,也可以是网络设备配置的,本申请对此不进行限定。
需要说明的是,criterion S表示的意思是当Srxlev>0AND Squal>0,终端不进行小区选择。其中Srxlev=Qrxlevmeas–(Qrxlevmin+Qrxlevminoffset)–Pcompensation-Qoffsettemp;Squal=Qqualmeas–(Qqualmin+Qqualminoffset)-Qoffsettemp。其中参数列表如下表所示。
其中,s-MeasureConfig是为让终端是否进行非服务小区测量的一个RSRP阈值。该阈值可以是基于SSB的RSRP,也可以是基于CSI-RS的RSRP。
需要说明的是,该Qrxlevmeas值可以是使srxlev=0的值,也可以是使squal=0的值。
应理解,该offset1或offset2可以是0,2,4,4.5,6,8,9,10,12,14,16,18,20,22,24,26,28,30中的任意一项。
可选地,该测量条件可以是测量结果与至少一个参考信号索引的映射关系。
具体地,该参考信号索引可以是1个也可以是多个。例如,一部分参考信号索引可以用于指示可以进行RRM测量的松弛,另一部分参考信号索引可以用于指示不可以进行RRM测量的松弛。若该测量条件中仅包括一个参考信号索引(例如第一参考信号索引),则在一种场景中,该第一参考信号索引可以指示进行RRM测量的松弛;在另一种场景中,该第一参考信号索引也可以指示不可以进行RRM测量的松弛。
可选地,参考信号索引可以是CSI-RS索引,也可以是SSB索引,或者还可以是DMRS索引,功率节省信号索引,追踪信号的索引,以及其他参考信号索引。
具体地,CSI-RS索引具体可以是CSI-RS资源指示,还可以是CSI-RS资源指示的索引。
应理解,CSI-RS资源指示可以是通过CSI-RS资源索引实现,也可以通过其他方式实现,本申请对此不进行限定。
可选地,该测量条件具体可以是测量结果与至少一个同步信号块索引的映射关系。例如,若SSB索引指示该信号为小区边缘的索引,则终端可以不进行RRM测量的松弛。这样避免终端在小区边缘进行RRM测量的松弛,影响终端的小区切换,从而使得终端的性能下降。也就是说,本申请实施例提高了终端的性能。
可选地,网络设备可以通过比特位图(bitmap)配置参考信号索引。
具体地,bitmap可以与参考信号索引具有映射关系。该bitmap可以基于单个参考信号索引进行映射,也可以基于参考信号组进行映射。例如,参考信号的数目为8个,使用8个比特位进行映射该8个参考信号的参考信号索引。
需要说明的是,在bitmap基于单个参考信号索引进行映射的情况下,bitmap中的每个比特位可以与单个参考信号索引具有映射关系,或者bitmap中的所有比特的不同取值分别与的单个参考信号索引具有映射关系。
还需要说明的是,比特位的取值“0”指示可以进行RRM测量的松弛,比特位的取值“1”指示不可以进行RRM测量的松弛。例如,使用00110010表示参考信号索引(index)的index2,index3和index6不可以进行RRM测量的松弛。
可选地,该测量条件具体可以是测量结果与至少一个同步信号块索引的映射关系。
具体地,该同步信号块的索引可以是1个或多个,一部分同步信号块索引可以用于指示可以进行RRM测量的松弛,另一部分同步信号块索引可以用于指示不可以进行RRM测量的松弛。
可选地,网络设备可以通过比特位图(bitmap)配置该同步信号块索引。
具体地,bitmap可以与同步信号块索引具有映射关系。该bitmap可以基于的那个同步信号块进行映射,也可以基于同步信号块组进行映射。例如,16个SSB分成4组,每组有4个SSB,这样需要8bit就可以指示是否进行RRM测量。
需要说明的是,在bitmap基于单个同步信号块索引进行映射的情况下,bitmap中的每个比特位可以与单个同步信号块索引具有映射关系,或者bitmap中的所有比特的不同取值分别与的同步信号块索引具有映射关系。例如,0000对应SSB0,0001对应SSB1。
可选地,该测量条件可以是测量结果与至少一个运动速度阈值的大小关系。
具体地,运动速度可以是指终端的运动速度,也可以是指网络设备的运动速度。
可选地,该测量条件可以是与至少一个运动速度阈值以及至少一个质量阈值的大小关系。
具体地,当终端的运动速度小于或等于V1的时候,终端根据质量阈值1和/或偏移1进行RRM测量的松弛;当终端的速度大于V1小于等于V2的时候,终端根据质量阈值2和/或偏移2进行RRM测量的松弛;当终端的速度大于V2或小于等于V3的时候,终端根据质量阈值3和/或偏移隔3进行RRM测量的松弛;当终端的速度大于V3的时候,终端不能进行RRM测量的松弛。
需要说明的是,该运动速度阈值可以是一个也可以是多个。例如,该运动速度阈值为2个,即V1和V3。
应理解,终端的速度反应量可以是多普勒频移,也可以是在一定时间段内经过的小区数目,也可以是在一定时间段内经过的SSB数目,也可以根据终端的定位来确定。终端的速率可以是网络设备指示的,也可以是终端根据自己的运动状态确定的。终端也可以向网络设备上报自己的速度。
还应理解,V1的值可以是1,2,3,4,5,6,7,8,9,10km/h中的任意一个值。V1的值可以是网络设备配置的,也可以是固定的(协议规定的或者是网络设备与终端约定的);V2的值可以是10,15,20,25,30,35,40,45,50,55,60km/h中的任意一个值。V2的值可以是网络设备配置的,也可以是固定的(协议规定的或者是网络设备与终端约定的);V3的值可以是60,70,80,90,100,110,120km/h中的任意一个值。V3的值可以是网络设备配置的,也可以是固定的(协议规定的或者是网络设备与终端约定的)。
可选地,该测量条件可以是与至少一个质量阈值的大小关系以及与至少一个同步信号块索引的映射关系。
具体地,不同的同步信号块可以对应不同的阈值,网络设备可以根据SSB索引配置不同的阈值。例如SSB0的松弛阈值为Th1,SSB1的松弛阈值为Th2。这些相同阈值下的SSB的索引可以为一个集合,高阈值下的SSB的索引集合可以包含低阈值下的SSB的索引集合,例如Th1>Th2,它们的参考信号索引集合分别为集合1和集合2。
可选地,该测量条件可以是与至少一个运动速度阈值的大小关系以及与至少一个参考信号索引的映射关系。
具体地,当终端的速度小于或等于V1时,终端对参考信号索引集合1中的参考信号进行RRM测量时可以进行RRM测量的松弛。当终端的速度大于V1小于等于V2的时候,终端对参考信号索引集合2中的参考信号进行RRM测量时可以进行RRM测量的松弛。 当终端的速度大于V2或小于等于V3的时候,终端参考信号索引集合3中的参考信号进行RRM测量时可以进行RRM测量的松弛。当终端的速度大于V3的时候,终端不能进行RRM测量的松弛。
需要说明的是,参考信号的集合1,集合2,集合3可以是网络设备确定并配置给终端。或者参考信号的集合也可以是终端自己配置的,且终端还可以将自己配置的发送给网络设备。集合1,集合2,集合3可以是包含全部或者部分的参考信号索引。集合1,集合2,集合3之间可以重叠。
还需要说明的是,在配置参考信号的集合时,网络设备还可以采用差值的方法配置,例如集合2包含了全部的集合3,网络设备可以先配置集合3,在配置集合2的时候,只配置2中除了3剩余的部分,这样降低配置的开销。
例如,例如小区有8个SSB,其中SSB#1,3,4,6,7为集合2,SSB#6,7为集合3。网络设备也可以从大的集合中挑选部分用作小的集合进行配置,从而节省开销。第一种配置方法为先配置集合3配置的字段为0000 0011,在配置集合2,配置的字段为011100;第二种配置方法为配置集合2为01011011,再进行配置集合3为00011。网络设备在配置其中速度级别也可以增大或者减少,相应的集合级别也进行增大或者减少。
可选地,网络设备也可以根据终端的速度,终端测量信号的阈值,终端所在的SSB的位置这三者确定测量条件。
202,终端进行RRM测量得到测量结果。
具体地,终端对周期性信号进行测量,具体地可以是测量信道质量,测量是否接收到参考信号。相应地,测量信号得到的测量结果可以是信道质量大小、接收到的参考信号的索引、或者根据测量信号得到的终端的运动速度。
203,网络设备向终端发送该RRM测量的测量条件。相应地,终端从网络设备接收该RRM测量的测量条件。
需要说明的是,本实施例对步骤202或步骤203的先后顺序不进行限定。
还需要说明的是,终端设备获取的测量条件可以是与网络设备预先约定的,或者协议规定的,或者还可以是网络设备预先配置的,这样本实施例不需要执行步骤201和步骤203。
可选地,网络设备可以向终端发送指示信息,该指示信息用于指示该RRM测量的测量条件。
可选地,该指示信息可以承载在物理广播信道(physical broadcast channel,PBCH)、剩余最小***信息(remaining minimum system information,RMSI)、***信息块(system information block,SIB)1、SIB2、SIB3,媒体接入控制控制元素(media access control-control element,MAC-CE)、下行控制信息(down link control information,DCI)、无线资源控制(radio resource control,RRC)以及***信息中的任意一项。
204,终端确定测量结果是否满足该RRM测量的测量条件。
205,终端在确定测量结果满足该测量条件的情况下,对该RRM测量进行松弛。
具体地,网络设备确定RRM测量的测量条件,并将该测量条件告知终端,终端进行RRM测量并根据测量结果确定是否满足该测量条件,进而确定是否对该RRM测量进行松弛。也就是说,终端可以根据网络设备配置的测量条件灵活的对RRM测量的测量方式进 行调整,即使得终端采用合适的RRM测量方式进行RRM测量,从而有助于减少终端的功耗开销。
可选地,终端在不满足该测量条件的情况下,不对该RRM测量进行松弛。
具体地,通常情况下,终端具有一个固定的RRM测量周期,终端初始可以基于该RRM测量周期进行RRM测量。在终端满足该测量条件的情况下,对该RRM测量周期进行调整。在不满足该测量条件的情况下,采用该固定的该RRM测量周期进行RRM测量。
可选地,对该RRM测量进行松弛具体可以是增大所述RRM测量的周期,或减少测量样本数目,或减少邻区域的测量数目,或减少RRM测量波束的数目,或减少邻频的测量数目。也就是说,终端可以合理的调整RRM测量的测量方式,从而节省终端的功耗开销。
需要说明的是,邻区域可以是相邻小区。邻频是指相邻的频点,频点具体可以是是参考信号的频点。
可选地,终端对RRM测量进行松弛可以是根据前述offset确定的。
具体地,终端对不同的offset值或不同的质量阈值可以由不同的松弛,从而增加了RRM测量的灵活性,更进一步节省了终端的开销。例如,当终端测量到一个参考信号的测量值为Y,而网络设备配置的预设条件的阈值(质量阈值或运动速度阈值)为X。若Y比X大的值每大Z的倍数时,终端就可以将RRM测量周期增大一倍。其中,Z可以是1,2,3,4,5,6,7,8,10dB中的任意一个值。
例如,Z为3dB,则测量周期增大一倍,有正比关系。若X为-120dBm,当Y的值为-117dBm的时候,RRM测量的周期可以增大一倍。其中,RRM测量的周期增大一倍也可以提换为RRM周期的样本数目减少一半或者减少1个,也可以替换为RRM测量的波束减少一半,本申请对此不进行限定。
可选地,在步骤205之后,终端在进行RRM测量的松弛之后,还可以向网络设备发送反馈信息,该反馈信息用于指示松弛参数。
需要说明的是,网络设备在接收到该反馈信息之后,也可以对该终端进行小区切换,或者触发小区切换流程。
例如,该反馈信息可以指示测量周期增大的倍数,减少的测量样本的数目,滤波采用的样本的数目。
可选地,终端在步骤205之后可以进行小区切换,或者触发小区切换流程。
因此,本申请实施例的RRM测量的方法,网络设备确定RRM测量的测量条件,并将该测量条件告知终端,终端进行RRM测量并根据测量结果确定是否满足该测量条件,进而确定是否对该RRM测量进行松弛。也就是说,终端可以根据网络设备配置的测量条件灵活的对RRM测量的测量方式进行调整,即使得终端采用合适的RRM测量方式进行RRM测量,从而有助于减少终端的功耗开销。
