在本发明实施例中,终端设备可以包括但不限于移动台(Mobile Station,MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、用户设备(User Equipment,UE)、手机(handset)及便携设备(portable equipment)、车辆(vehicle)等,该终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,例如,终端设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等,终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。

如图1所示,本发明提供波束质量测量方法100的实施例,该方法可以由终端设备执行,换言之,该方法可以由安装在终端设备的软件或硬件来执行,该方法包括如下步骤:
S102:接收多个RS。
该实施例中,上述多个RS是网络设备通过目标发送波束发送的,终端设备采用目标接收波束接收这多个RS。具体如图2所示,其中,图2以网络设备是发送接收点(Transmission Receive Point,TRP)为例进行显示。
上述多个RS可以是用于波束质量测量的参考信号,具体例如,上述多个RS均为信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS);又例如,上述多个RS均为同步信号块(Synchronization Signal and PBCH block,简称SSB);再例如,上述多个RS是一个或多个CSI-RS以及一 个或多个SSB的组合。
可选地,上述多个RS满足准共址(Quasi Co-Location,QCL)关系,QCL关系用于表示这多个RS的资源之间具有一个或多个相同或者相类似的通信特征,这多个RS可以采用相同或者类似的通信配置。
S104:基于接收到的多个RS确定目标波束对的波束质量指标。
该目标波束对包括一个发送波束和一个接收波束,如图2所示,该发送波束即网络设备发送上述多个RS的发送波束;该接收波束即终端设备接收这多个RS的接收波束。
可选地,该步骤中终端设备可以基于接收到的多个RS以及这多个RS对应的所有天线端口,确定目标波束对的波束质量指标。
该实施例中,终端设备可以在上述多个RS的资源粒子(Resource Element,RE)上联合计算波束质量指标,该波束质量指标可以包括CSI参数(parameters)或计算波束质量等。
可选地,波束质量指标可以包括参考信号接收功率(Reference Signal Receiving Power,RSRP)、参考信号接收质量(Reference Signal Receiving Quality,RSRQ)和信号与干扰加噪声比(Signal to Interference plus Noise Ratio,SINR)中的至少一种。
可选地,终端设备可以将多个RS分别得到的波束质量指标通过如下至少之一的算法进行运算,得到目标波束对的波束质量指标:线性平均;几何平均;调和平均;平方平均;加权平均;最小值最大化;最大值最小化。当然,本发明实施例中的算法也不局限于上述示例及其简单变化。
具体例如,上述多个RS为两个,分别为第一RS和第二RS,终端设备可以将第一RS的波束质量指标(例如RSRP)和第二RS的波束质量指标(和第一RS的波束质量指标的种类相同,例如,均为RSRP)进行线性平均运算,将得到的结果作为目标波束对的波束质量指标。
本发明实施例提供的波束质量测量方法可以分以下三种过程:
P-1:UE测量TRP的多个发送波束和以及UE的接收波束,并选择TRP的发送波束和UE的接收波束。典型场景:TRP扫描多个发送波束,UE扫描多个接收波束。UE向TRP报告选择的至少一个TRP发送波束。
P-2:UE测量TRP的多个发送波束,并选择TRP的发送波束。典型场景:与P-1相比,实现小范围的更为精确的发送波束扫描,可以看作是P-1的特例。UE向TRP报告选择的至少一个TRP发送波束。
P-3:UE在TRP的同一个发送波束上测量UE的多个接收波束,并选择UE的接收波束。UE不向TRP报告。
可选地,针对上述过程P-1和P-2,在上述实施例的S104基于多个RS确定目标波束对的波束质量指标之后,还可以包括如下步骤:发送波束测量报告,该波束测量报告包括上述波束质量指标和目标RS的标识。
上述目标RS的标识和网络设备发送上述多个RS的发送波束之间存在关联关系,这样,网络设备在接收到目标RS的标识之后,即可识别出发送上述多个RS的发送波束,后续还可以通过该发送波束和终端设备之间进行数据或信号的传输。
该目标RS的标识为可以将该目标RS与其他RS相区分的信息,例如,可以将目标RS使用的序列作为信号标识,或者将生成目标RS的序列的循环移位作为信号标识,或者将该目标RS的编号为信号标识。
具体例如,目标RS为SSB,则目标RS的标识为SSB index;又例如,目标RS为CSI-RS,则目标RS的标识为CSI-RS index。
本发明实施例提供的波束质量测量方法,终端设备接收多个RS,并通过这多个RS联合确定目标波束对的波束质量指标,相对于相关技术中采用一个RS确定目标波束对的波束质量指标的方案而言,可以提升波束质量的测量精度、降低时域滤波时间,达到更快、更准的波束训练的目的。
以下将对本发明实施例提供的波束质量测量方法的实现原理进行详细解释:
相关技术中一个RS对应一个波束,网络设备无法通过增加RS来达到提升波束训练的速度和精度的效果。举例来说,假设终端设备可以采用8个接收波束,而网络设备给终端设备配置了16个RS,那么网络可以每2个RS对应终端设备一个波束。但终端设备只能在每个RS自己的RE上进行检测,而且在波束报告中,终端设备只能上报每个RS自己的波束质量,这样就无法使资源得到最大限度的利用。
本发明实施例提出多个RS联合检测目标波束对的波束质量指标,同样是上面这个例子,终端设备可以在2个RS的RE上测量该波束的质量并且线性平均,这样就是使波束测量的收敛速度提升了一倍。如果一个波束使用更多的RS来检测,那么波束测量的收敛速度也就能提升地更多。
而且,网络设备可以根据***中RS资源数目、终端设备数目、终端设备业务类型,来灵活配置波束训练,提升***性能。
例如,终端设备数目比较多时,每个终端设备的波束训练的RS就相对少配置一些(仍然可以是多个),训练速度降低一些;终端设备数目比较少时,每个终端设备的波束训练的RS就可以相对多配置一些,加速训练。举例来说,假设当前小区的终端设备数较少,网络设备可以发送多一些的RS,多个RS提高了波束测量的精度。假设当前小区的终端设备数较多,网络设备可以少发送一些的RS,减少占用的下行资源,提升下行***容量。
对于重要的、信道质量要求高的业务,可以通过配置更多的RS,使得波束训练更准确;对于信道质量要求一般的业务,就可以降低波束训练的要求。
对于上述提到的降低时域滤波时间,以下将对其原理进行详细说明:
由于终端设备对波束检测(或称测量)存在误差,波束本身也会随着时间进行变化,单次测量的结果往往不准。因此波束测量的结果需要进行时域上的层1滤波,通过多个时间上的测量,来提升测量精度、降低时变性的影响。甚至,还要在层1滤波的结果基础上,再进行层3滤波,来进一步提升波束测量的质量。
而本发明实施例通过提高RS的数量,通过多个RS联合确定目标波束对的波束质量指标,可以提升波束质量的测量精度。同时,这多个RS的时域资源可以比较接近,甚至可以占用相同的时域资源(通过频域区分),可以减少甚至省略上述层1滤波和层3滤波,因此可以降低时域滤波时间。
可选地,本发明实施例还可以考虑在对现有协议的影响尽量小的情况下,实现多个RS联合检测的功能,为达到上述效果,本发明实施例考虑了三种不同的配置方法,都是对现有协议的改动较小的方法,以下将分三个实施例,对多个RS联合检测单个波束的具体配置方法进行详细介绍。
实施例一
上述多个RS(实施例100的S102中的接收的多个RS,后续类同)是通过高层信令配置的,该高层信令包括下述之一:
1)CSI测量配置信令(CSI-MeasConfig);
2)CSI报告配置信令(CSI-ReportConfig);
3)CSI资源配置信令(CSI-ResourceConfig);
4)非零功率CSI-RS资源集信令(NZP-CSI-RS-ResourceSet);或
5)CSI-SSB资源集信令(CSI-SSB-ResourceSet)。
具体例如,在高层配置信令中配置某高层信令的状态为“on”,通过该高层信令可以指示终端设备接收上述多个RS。
实施例一中,在终端设备发送波束测量报告的情况下,波束测量报告中包括目标RS的标识,该目标RS可以是上述高层信令关联的所有RS中:
标识号最大的;
标识号最小的;
第一个配置的;
最后一个配置的;或
任意的一个。
可以理解,在目标RS是上述高层信令关联的所有RS中的标识号最大的、 标识号最小的、第一个配置的或最后一个配置的这几种情况下,网络设备在为终端设备配置上述多个RS时,是已经知道终端设备后续上报的目标RS具体是哪一个。
在目标RS是上述高层信令关联的所有RS中的任意的一个的这种情况下,网络设备在配置上述多个RS时,通常是不知道终端设备后续可能上报哪一个RS的标识,网络设备只有在接收到波束测量报告包括的(目标)RS的标识之后才知晓,后续可以使用该(目标)RS进行波束相关的指示。
需要说明是的,本说明书各个实施例中提到的第一个/最后一个配置的RS,具体可以是指RS在配置中的顺序为第一个/为最后一个,例如,网络设备同时配置了多个RS,那么第一个配置的RS就是配置顺序中的第一个,最后一个配置的RS就是配置顺序中的最后一个。
还需要说明是的是,本说明书各个实施例中提到的高层信令“关联”的RS,其中的“关联”还可以用其他类似的技术术语来替代,例如,“指示”、“配置”等。
具体例如,在高层信令是CSI测量配置信令(CSI-MeasConfig)时,该高层信令可以和CSI资源配置信令(CSI-ResourceConfig)关联,而CSI资源配置信令可以用来配置资源集,上述多个RS包含于该资源集内,在这种情况下,高层信令—CSI测量配置信令关联的RS,可以是CSI资源配置信令配置的资源集中的包括的多个RS。同样,CSI测量配置信令也可以直接配置RS资源和/或RS资源集,高层信令—CSI测量配置信令关联的RS,可以是其配置的多个RS和/或RS资源集中包括的多个RS。
又例如,在高层信令是CSI资源配置信令(CSI-ResourceConfig)时,该高层信令可以配置资源集,上述多个RS包含于该资源集内,在这种情况下,高层信令—CSI资源配置信令关联的RS,还可以称作是高层信令—CSI资源配置信令配置的RS。
又例如,在高层信令是CSI报告配置信令(CSI-ReportConfig)时,该高 层信令可以和CSI资源配置信令关联,而CSI资源配置信令可以用来配置资源集,上述多个RS包含于该资源集内,在这种情况下,高层信令—CSI报告配置信令关联的RS,可以是CSI资源配置信令配置的资源集中的包括的多个RS。
可选地,波束测量报告中包括的目标RS可以是网络设备配置指示的,也可以是终端设备自主选择的,也可以是协议约定的。具体例如,协议约定终端设备发送的波束测量报告中包括的目标RS,是高层信令关联的所有RS中第一个配置的。
可选地,上述高层信令的重复开启配置(repetition)可以为开启状态,这样,网络设备可以通过同一个发送波束重复发送上述多个RS,便于终端设备扫描其多个接收波束,以确定波束质量较好的一个或多个接收波束。
可选地,实施例一中的上述高层信令关联的RS均配置了相同的QCL信息。
可选地,实施例一中的上述高层信令关联的RS(目标RS除外,因为上述高层信令关联的RS也可能包括目标RS)的QCL信息遵循(follow)目标RS的QCL信息,该目标RS即上述多个RS中用于波束测量报告的RS。该实施例中,高层信令关联的RS(目标RS除外)如果配置了QCL信息,则无论这些RS的QCL信息与目标RS的QCL信息是否相同,这些RS均可以忽略原始配置的QCL信息,而遵循目标RS的QCL信息;当然,如果高层信令关联的RS(目标RS除外)未配置QCL信息,则这些RS可以直接遵循目标RS的QCL信息。
实施例二
上述多个RS包含于网络设备配置的RS列表(list)中,该RS列表中包括多个RS的标识。
该实施例中,网络设备可以配置一个或多个RS列表。在一个例子中,网络设备配置多个RS列表,一个RS列表关联网络设备的一个发送波束,任意的两个RS列表关联的发送波束不同。
实施例二中,在终端设备发送波束测量报告的情况下,波束测量报告中包 括目标RS的标识,该目标RS可以是RS列表中:
标识号最大的;
标识号最小的;
第一个配置的;
最后一个配置的;
任意的一个;或
网络设备指示的(例如,网络设备在RS列表中单独标注出的)。
可选地,波束测量报告中包括的目标RS可以是网络设备配置指示的,也可以是终端设备自主选择的,也可以是协议约定的。具体例如,协议约定终端设备发送的波束测量报告中包括的目标RS,是RS列表中第一个配置的。
可选地,RS列表中的RS包含于同一个资源集(resource set)。当然,RS列表中的RS也可以属于不同的资源集。
实施例三
上述多个RS配置了相同的QCL信息,或上述多个RS中的一个RS被配置为另外一个或多个RS的QCL信息。
可选地,上述多个RS配置了相同的QCL信息,在终端设备发送波束测量报告的情况下,波束测量报告中包括目标RS的标识,该目标RS是上述多个RS中:

在该实施例中,如果满足上述要求的RS(即报告量被配置为上述之一的RS)为多个,则波束测量报告中包括的目标RS可以是满足要求的多个RS中的任意一个,或者是标识号最大的,或者是标识号最小的。
可选地,上述多个RS配置了相同的QCL信息,在终端设备发送波束测量报告的情况下,波束测量报告中包括目标RS的标识,该目标RS:
优先为SSB;
优先为CSI-RS;
是按照所述终端设备选择的优先级确定的,例如,终端设备选择目标RS优先为SSB;或
是按照网络设备配置的优先级确定的,例如,网络设备配置指示目标RS优先为SSB。
可选地,波束测量报告中包括的目标RS可以是网络设备配置指示的,也可以是终端设备自主选择的,也可以是协议约定的。具体例如,协议约定终端设备发送的波束测量报告中包括的目标RS,是RS列表中第一个配置的。
可选地,在上述多个RS中的一个RS被配置为另外一个或多个RS的QCL信息的情况下,这“一个RS”是目标RS,即,多个RS中目标RS被配置为另外一个或多个RS的QCL信息。
可选地,多个RS中至少一个RS所属于的高层信令中,配置某高层信令为“on”,以触发该实施例的通过多个RS联合检测目标波束对的波数质量指标。

该实施例考虑RS的不同用途,对于时效性要求高的RS类型,例如,用于波束失败检测(Beam Failure Detection,BFD)的RS,或用于无线链路监听(Radio Link Monitoring)的RS,可以协议要求或优先进行多个RS联合检测目标波束对的波数质量指标。
