具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述。
图1示出了本申请实施例提供的一种通信系统100,该通信系统100可包括网络设备101和终端设备102。
其中,网络设备101,可以为终端设备102提供无线接入有关的服务,实现下述功能中的一个或多个功能:无线物理层功能、资源调度和无线资源管理、服务质量(quality of service,Qos)管理、无线接入控制以及移动性管理功能。终端设备102可通过空口,接入网络设备101。在本申请实施例中,网络设备101与终端设备102可通过波束进行通信。
本申请提供一种波束质量测量的方法,具体为:网络设备101可通过第一波束向终端设备102发送第一参考信号,终端设备102可根据在第一波束上所接收的第一参考信号,生成第一波束的波束质量测量报告,且终端设备102反馈所述第一波束的波束质量测量报告至网络设备101。
在本申请的一示例中,终端设备102所反馈的第一波束的波束质量测量报告的格式可如下{第一波束标识,第一参考信号的接收功率}。可见,终端设备102所反馈的第一波束的波束质量测量报告中包括两部分内容,分别为第一波束标识以及第一波束上所接收第一参考信号的功率,空口开销比较大。
比如,以总共包括64个波束为例,每个波束的标识需占用6比特(log 264=6)。同时在64个波束中,参考信号的接收功率最大的波束需占用7比特,其余63个波束的参考信号接收功率采用差分方式,均需占用4比特。也就是说,按照上述所规定的反馈波束质量测量报告的格式,在64个波束的情况下,其中一个波束的质量测量报告需占用13比特,其余63个波束的质量测量报告分别需占用10比特,如果终端设备反馈64个波束的质量测量报告,那么共总需占用13+10*63=643比特,空口开销较大。
基于上述,本申请提供一种通信方法,该通信方法可减少终端设备所反馈波束质量测 量报告的开销,主要原理为:终端设备在通过第一波束接收到第一参考信号时,根据第一参考信号以及第一门限,确定第一波束的可用性,然后直接反馈第一波束的可用性至网络设备。相对于反馈第一波束标识以及第一参考信号的接收功率至网络设备,可减少空口开销。

在本申请实施例中,可为每个CSI资源集合均分配一个资源集合ID,每个CSI资源集合中可包括一个或多个资源,每个资源也设有自己的标识,一个资源集合最大的资源数目为一个CSI-RS资源集合中最大的非零功率CSI-RS资源的数目(maxNrofNZP-CSI-RS-ResourcesPerSet)。
波束可用性门限的配置信息:
在本申请实施例中,可为终端设备配置一个或多个门限,所述门限可以为RSRP、RSRQ、RSSI、SINR以及CQI中的一个或多个为度量。上述一个或多个门限中,至少一个门限是与波束失败恢复配置的门限相关的。
反馈波束可用性的配置信息:在本申请实施例中,反馈波束可用性的配置信息中可包括反馈波束可用性的上报的内容以及格式等,以及上波的资源配置等。关于上述第三部分内容,将在步骤S505中详细说明。
步骤S502:终端设备接收第一配置信息。
步骤S503:网络设备根据上述第一配置信息中的参考信号的配置信息,发送参考信号。
步骤S504:终端设备根据上述第一配置信息中的参考信号的配置信息,接收参考信号,并测量参考信号。
在本申请实施例中,通过对参考信号进行测量,可确定波束质量,所述波束质量可通过以下参数中一种或多种进行反馈:BLER、RSRP、RSRQ、RSSI、SINR、CQI以及PMI等。
可选的,网络设备也可确定参考信号的测量方法,比如,网络设备如果要求终端设备上报RSRP,那么终端设备可仅测量终端设备的RSRP即可。
步骤S505:终端设备反馈波束可用性消息。
在本申请实施例中,终端设备可通过1个二进制比特,反馈每个波束的可用性,比如, 当波束的质量满足波束可用性门限时,可标记为1,当波束的质量未满足波束可用性门限时,可标识为0。
比如,当整个CSI资源信合中可包括8个CSI-RS集合,按照CSI-RS标识的从大到小的顺序,分别为1,4,6,9,13,15,24,63。其中,标识为1,9,13,63的资源,UE测量满足门限,UE可以反馈8比特的bitmap{10011001},UE反馈的信息说明按资源标识从小到大的顺序,第1,4,5,8个资源满足门限。
在本申请实施例中,终端设备反馈波束可用性的信令格式可以为MAC-CE,也可以为DCI。
比如,当UE反馈的信令格式为MAC PDU时,如图3所示,该MAC PDU中可包括报文头以及MCE-CE,所述报文头可以示例性的称为波束可用性上报,当一个资源集合中包括64个CSI-RS,即一次性测试64个波束的可用性时,MAC-CE示例性的可如图6所示,所述MAC-CE中可包括8个Oct,一个Oct为一个字节,包括8比特,图4中的一个小方格代表一比特,代表一个波束的可用性。图6所示的MAC-CE可为一定长的64比特的MAC CE,所述C的值可为1或0,C的下标表示资源集合中从小到大排序的资源标识。
在本申请实施例中,UE反馈波束可用性的信令格式可以为UCI,所述UCI可为定长的或变长的。以64比特的定长UCI为例,第一个比特表示资源集合中的从小到大排序的第一个资源标识,且当标识对应的波束质量满足门限时,取值为1,第二个比特表示资源集合中的从小到大排序的第二个资源标识,且当标识对应的波束质量不满足门限时,取值为0,依次类推,直至第六十四个比特。
在本申请实施例中,可选的,终端设备的波束上报可与下述方式相结合。比如,波束质量的一种上报方式为{波束#1标识、波束#1的RSRP}。本申请实施例中的64比特的bitmap可以反馈其他波束与波束#1的相关性高低,例如“1”表示和波束#1相关性高,“0”表示和波束#1相关性低。又例如,本申请实施例的64比特的bitmap可以反馈其他波束对波束#1的干扰程度,例如,“1”表示对波束#1干扰高,“0”表示对波束#1干扰低。其他例子还包括,该波束和波束#1是否适合构成多波束传输信道,该波束和波束#1是否适合构成高鲁棒性传输组合等。
上述方法还可以自然的扩展到终端设备通过现有上报方式上了多个波束的情况,例如,UE上报了{波束#1+波束#1的L1-RSRP}{波束#2+波束#2和波束#1的差分L1-RSRP}。本实施例的64比特bitmap可以自然的扩展到两个64比特的bitmap,分别对应波束#1和波束#2的情况。这两个bitmap可以分组上报或者分次上报。
可选的,终端设备可以通过M个比特来反馈每个波束的可用性。如果501中配置的波束可用性门限有M个时,每个比特可以对应一个门限,例如当门限有两个时,每个波束可以反馈两个比特,第一个比特表示波束质量是否满足第一门限,第二个比特表示波束质量是否满足第二门限。
可选的,终端设备可以通过M个比特来反馈每个波束的可用性。例如波束质量分为N个区间,UE可以通过M={上取整log2(N)}个比特来反馈每个波束质量属于哪个区间。区间的划分可以根据绝对的波束质量,例如RSRP按-100dBm到-50dBm为区间1,-150dBm到-100dBm为区间2。也可以根据相对的波束质量,例如与最强波束相差0dB到10dB为区间1,与最强波束相差10dB到20dB为区间2。
可选的,bitmap的长度可以是资源集合的大小,也可以是资源集合中最大允许的资源 数目,例如64。bitmap的长度可以是资源集合的大小*M,也可以是资源集合中最大允许的资源数*M。bitmap中每个比特对应的资源标识的顺序是可配的,例如从小到大或者从大到小。
在本申请实施全名,并不限于bitmap反馈波束的可用性,还可使用显式的资源标识编号,或者逻辑的资源标识编号等方式,反馈波束的可用性。
步骤S506:网络设备接收波束可用性消息。
在本申请实施例中,网络设备在接收到波束可用性消息后,可更新配置,从而更合理的利用资源。
比如,网络设备可以将终端设备的可用资源(例如,反馈为1的资源)的全部或者部分配置为新的波束管理资源集合。
或者,网络设备可以不将不可用的资源(例如,反馈为0的资源)配置到新的波束管理资源集合。
或者,网络设备可以将可用的资源(例如,反馈为1的资源)的全部或者部分配置为新的可用波束的资源集合。
或者,网络设备可以不将不可用的资源(例如,反馈为0的资源)配置到新的可用波束的资源集合。
或者,网络设备可以将可用的资源(例如,反馈为1的资源)的全部或者部分配置为波束指示(例如TCI)的集合。
或者,网络设备可以不将不可用的资源(例如,反馈为0的资源)配置到波束指示(例如TCI)的集合。
或者,网络可以将终端设备的不可用资源(例如,反馈为0的资源)用来服务其它终端设备,从而不对上述终端设备造成干扰。
在本申请实施例中,可低开销的反馈每个波束的可用性,提供网络设备侧更多的信息,有利于网络设备侧合理的配置波束相关的资源。
