Description

一种传输信道质量信息的方法和装置
本申请要求于2017年11月17日提交中国专利局、申请号为201711148332.4、申请名称为“一种传输信道质量信息的方法和装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,尤其涉及一种传输信道质量信息的方法和装置。
背景技术
移动业务的发展对无线通信的数据速率和效率要求越来越高。在5G以及未来无线通信系统中,波束赋形技术用来将传输信号的能量限制在某个波束方向内,从而增加信号通信效率。波束赋形技术能够有效扩大无线信号的传输范围,降低信号干扰,从而达到更高的通信效率和获取更高的网络容量。
在采用波束赋形技术的通信网络中,需要通过波束训练或者波束管理,使得终端通过某一特定的接收波束接收到的信号来自网络设备的某一特定的发送波束,该特定的接收波束和该特定的发送波束构成一个波束对,从而获得比较好的信号质量,否则无法取得比较高的通信效率甚至无法进行通信。作为一个示例,波束训练或波束管理的具体流程如下:网络设备向终端发送一个或多个波束赋性的参考信号;终端通过一个或多个接收波束接收网络设备发送的波束赋性的参考信号,然后,根据所接收的参考信号估计出多个信道质量,并向网络设备上报所估计出的信道质量中的最好的几个信道质量。网络设备根据该最好的几个信道质量选择一个波束对。信道质量可以包括但不限于是参考信号接收功率(reference signal received power,RSRP)。
终端向网络设备上报信道质量之前,需要对实际测量得到的信道质量进行量化。目前,通常采用的方法是:为减小上报开销,采用差分方式上报信道质量信息,先选定一个参考信道质量,然后根据该参考信道质量和固定的1db量化步长对非参考信道质量(或者说是差分信道质量)进行量化。由于非参考信道质量的量化比特数是固定值4比特,因此若采用上述方法对非参考信道质量进行量化,则会导致非参考信道质量的量化值的取值范围受限,从而降低系统整体性能增益。

具体实施方式
本申请中的术语“多个”是指两个或两个以上。本申请中的术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。本申请中的术语“第一”、“第二”等是为了区分不同的对象,并不限定该不同对象的顺序。
本申请提供的技术方案可以应用于各种通信系统,例如,在现有通信系统的基础上引入了波束,5G通信系统,未来演进系统或多种通信融合系统等等。可以包括多种应用场景,例如,机器对机器(machine to machine,M2M)、D2M、宏微通信、增强型移动互联网(enhance mobile broadband,eMBB)、超高可靠性与超低时延通信(ultra reliable&low latency communication,uRLLC)以及海量物联网通信(massive machine type communication,mMTC)等场景。这些场景可以包括但不限于:终端与终端之间的通信场景,网络设备与网络设备之间的通信场景,网络设备与终端之间的通信场景等。本申请提供的技术方案也可以应用于5G通信系统中的终端与终端之间的通信,或网络设备与网络设备之间的通信等场景中。
图1给出了本申请提供的技术方案所适用的一种通信系统的示意图,该通信系统可以包括一个或多个网络设备100(仅示出了1个)以及与每一网络设备连接的一个或多个终端200(仅示出了1个)。图1仅为示意图,并不构成对本申请提供的技术方案的适用场景的限定。
网络设备100可以是能和终端200通信的设备。网络设备100可以是传输节点(transmission reference point,TRP)、基站、中继站或接入点等。网络设备100可以是全球移动通信系统(global system for mobile communication,GSM)或码分多址(code division multiple access,CDMA)网络中的基站收发信台(base transceiver station,BTS),也可以是宽带码分多址(wideband code division multiple access,WCDMA)中的NB(NodeB),还可以是长期演进(long term evolution,LTE)中的eNB或eNodeB(evolutional NodeB)。网络设备100还可以是云无线接入网络(cloud radio access network,CRAN)场景下的无线控制器。网络设备100还可以是5G通信系统中的网络设备或未来演进网络中的网络设备;还可以是可穿戴设备或车载设备等。
终端200可以是用户设备(user equipment,UE)、接入终端、UE单元、UE站、移动站、移动台、远方站、远程终端、移动设备、UE终端、无线通信设备、UE代理或UE装置等。接入终端可以是蜂窝电话、无绳电话、会话开启协议(session initiation protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字处理(personal digital assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,5G网络中的终端或未来演进的PLMN网络中的终端等。
波束是一种通信资源。波束可以分为发送波束和接收波束。发送波束,可以理解为:信号经天线发送出去后在空间不同方向上形成的信号强度的分布,接收波束,可以理解为:从天线上接收到的无线信号在空间不同方向上的信号强度分布。不同的波束可以认为是不同的资源。使用不同的波束可以发送相同的信息或不同的信息。可选的,可以将具有相同或类似的通信特征的多个波束视为是一个波束。一个波束内可以包括一个或多个天线端口,用于传输数据信道信息,控制信道信息和探测信号等。波束在协议中可以例如但不限于体现为空域滤波器(spatial filter)、参考信号资源索引,准共址(quasi co location,QCL)等信息。
波束对(beam pair link,BPL)建立在波束的概念上。一个波束对包括发送端设备的一个发送波束和接收端设备的一个接收波束。在上行方向上,发送端设备可以是终端,接收端设备可以是网络设备。在下行方向上,发送端设备可以是网络设备,接收端设备可以是终端。
在通信系统例如5G新空口(new radio,NR)系统中,网络设备和终端均可生成一个或多个波束。作为一个示例,在传输信号之前,需要进行波束对准。另外,在终端移动或者信道质量变更的情况下,可能需要进行波束对切换,从而使用新的波束对进行通信等。例如但不限于在波束对准,或者波束切换场景中,需要终端向网络设备上报至少两个信道质量。信道质量可以例如但不限于包括以下至少一种:RSRP,参考信号接收质量(reference signal receiving quality,RSRQ),信干噪比(signal to interference plus noise ratio,SINR)、信噪比(signal to noise ratio,SNR)。下文中的具体示例均 是以信道质量是RSRP为例进行说明的。
终端向网络设备上报的信道质量之前,需要对实际测量得到的信道质量进行量化。目前,通常采用的方法是:先选定一个参考信道质量,然后根据该参考信道质量和固定的1db量化步长对非参考信道质量进行量化。由于非参考信道质量的量化比特数是固定值4比特。因此非参考信道质量的量化值的取值范围是16dbm,采用上述方法对非参考信道质量进行量化会导致量化后的取值范围过小,从而导致量化损失过大,降低系统整体性能增益。例如,假设实际测量得到的信道质量的值分别是:-135dbm,-125dbm,-90dbm,-138dbm;若将这4个信道质量中的最大值即-90dbm作为参考信道质量,则非参信道质量的量化值的取值范围是区间[-105dbm,-90dbm],基于此,非参考信道质量(即-135dbm、-125dbm和-138dbm)的量化值均是-105dbm。由此可以看出,采用现有技术提供的量化方法,会导致成量化损失较大(或量化精确度较低),从而导致系统整体性能增益不高。
基于此,本申请提供了一种传输信道质量信息的方法和装置,下面结合附图对本申请提供的传输信道质量信息的方法和装置进行说明。
如图2所示,为本申请提供的一种传输信道质量信息的方法,该方法可以包括如下步骤:
S101:网络设备通过X个发送波束向终端发送一个或多个参考信号。
其中,该X个发送波束可以是网络设备的部分或全部发送波束。X是大于等于1的整数。通过不同发送波束发送的参考信号之间可以进行资源复用,例如通过时分、频分、码分方式或其结合方式进行时域和/或频域资源复用。
S102:终端分别通过Y个接收波束中每个接收波束,接收网络设备的每个发送波束发送的参考信号。
其中,该Y个接收波束可以是终端的部分或全部接收波束。Y是大于等于1的整数。
S103:终端根据接收到的参考信号,估计出经网络设备的X个发送波束中的每个发送波束到终端的Y个接收波束中的每个接收波束传输的参考信号的信道质量,共X*Y个信道质量。其中,这里的信道质量是指实际测量得到的信道质量。
例如,假设X=3,Y=2,网络设备的X个发送波束是发送波束1、2、3,终端的Y个接收波束是接收波束a、b。那么,S101~S103具体可以是:网络设备通过发送波束1、2、3分别发送参考信号1、2、3;终端通过接收波束a接收参考信号1、2、3,并通过接收波束b接收参考信号1、2、3,然后,根据所接收的参考信号确定X*Y(即6)个信道质量,分别是:通过发送波束1与接收波束a传输的参考信号1的信道质量,通过发送波束2与接收波束a传输的参考信号2的信道质量,通过发送波束3与接收波束a传输的参考信号3的信道质量,通过发送波束1与接收波束b传输的参考信号1的信道质量,通过发送波束2与接收波束b传输的参考信号2的信道质量,通过发送波束3与接收波束b传输的参考信号3的信道质量。
S104:终端从X*Y个信道质量中选择出满足预设条件的K个信道质量。
其中,2≤K≤X*Y,K是整数。K的取值可以是网络设备向终端配置的,或者终端根据自身的能力确定的,本申请对此不进行限定。
满足预设条件的信道质量通常是用于表示信道条件较好的信道质量。以信道质量是RSRP、RSRQ、SINR或SNR中的其中之一为例,满足预设条件的K个信道质量可以是信道质量大于或等于某一阈值的K个信道质量,或者可以是X*Y个信道质量按照信道质量由高到低排序后得到的序列中的前K个信道质量。其他示例不再一一列举。
在一个示例中,针对网络设备的每一发送波束,终端通常至多向网络设备发送一个信道质量。基于此,S104中选择出的K个信道质量中的每个信道可以对应一个发送波束。例如,基于上述S103中的示例,终端从6个信道质量中选择出的K个信道质量可以包括以下信道质量中的至少一个:发送波束1对应的一个信道质量,发送波束2对应的一个信道质量,发送波束3对应的一个信道质量。
S105:终端确定K个信道质量的参考信道质量。
作为一个示例,参考信号质量可以是终端根据K个信道质量确定的至少一个值,例如,可以是该K个信道质量中的最大值、最小值和平均值中的至少一个值,当然本申请不限于此。其中,若参考信道质量包括多个值,则通常是两个值,例如可以是K个信道质量中的最大值和最小值,也可以是K个信道质量中的最大值和平均值等。为了方便描述,如果不加说明,下文中所示的参考信道质量均是以一个值为例进行说明的。参考信道质量的确定规则,即参考信道质量有一个还是多个和/或具体是K个信道质量中的什么值等,可以是预定义的例如协议中预定义的,或者可以是网络设备通过信令向终端配置的。
作为一个示例,参考信号质量可以是网络设备根据终端的历史通信信息确定并通过信令向终端配置的至少一个值。需要说明的是,本申请涉及到的任意一个信令(例如配置参考信道质量的信令等)均可以是RRC信令、MAC信令和DCI中的至少一种。下文中不再赘述。
可以理解的,若参考信道质量是该K个信道质量中的平均值,则该参考信道质量可能不是该K个信道质量中的值。实际实现时,参考信道质量可以是该K个信道质量中的值,也可以不是该K个信道质量中的值,还可以有的参考信道质量是该K个信道质量中的值,有的参考信道质量不是该K个信道质量中的值。
S106:终端确定第一量化步长。
其中,本申请对第一量化步长的设置方式不进行限定,例如,第一量化步长可以是一个预定义的值,例如固定值1db。当然本申请不限于此。
S107:终端根据第一量化步长对参考信道质量进行量化,得到参考信道质量的量化值。
作为一个示例,根据第一量化步长对参考信道质量进行量化,具体可以是:根据第一量化步长,在第一量化范围内对参考信道质量进行量化。其中,本申请中将第一量化范围标记为区间[A,B],其中,A小于B。
例如,以信道质量是RSRP为例,第一量化范围可以是区间[-140dbm,-44dbm],当然不限于此。以第一量化范围是区间[-140dbm,-44dbm]为例,假设K=4,4个信道质量分别是:-135dbm、-134dbm、-146dbm、-138dbm,那么,若参考信道质量是这4个信道质量中的最大值即-134dbm,由于-134dbm属于区间[-140dbm,-44dbm],因此,该情况下,参考信道质量的量化值是-134dbm。若参考信道质量是这4个信道质量中 的最小值即-146dbm,由于-146dbm不属于区间[-140dbm,-44dbm],因此,该情况下,参考信道质量的量化值是[-140dbm,-44dbm]中的最小值,即-140dbm。
可以理解的,若第一量化范围是区间[-140dbm,-44dbm],且第一量化步长是1db,则参考信道质量可能的量化值构成的集合是{-140dbm,-139dbm,-138dbm……-44dbm},因此,可以使用7比特(即共2 7=128个状态)来指示参考信道质量的量化值,即参考信道质量的量化比特数是7比特。
S108:终端根据参考信道质量的量化值确定第二量化步长。
若参考信道质量有两个值,则终端可以根据其中的任意一个值确定第二量化步长。至于终端使用其中的哪一个值可以是预定义的例如协议中预定义的,或者网络设备通过信令向终端配置的。
本申请中,第二量化步长与参考信道质量的量化值相关(或具有映射关系)。该映射关系可以是预定义的,具体可以例如但不限于通过表格或者公式等来体现。
下面列举本申请提供的几种第二量化步长与参考信道质量的量化值相关的具体实现:
方式1:若参考信道质量的量化值小于阈值,则确定第二量化步长是M。若参考信道质量的量化值大于或等于阈值,则确定第二量化步长是N;其中,M不等于N。
可选的,当参考信道质量是K个信道质量中的最大值时,M小于N。当参考信道质量是K个信道质量中的最小值时,M大于N。
例如,阈值-109dbm,M=2db,N=4db。假设K=4,4个信道质量分别是:-135dbm,-125dbm,-90dbm,-138dbm。那么,若参考信道质量是这4个信道质量中的最大值即-90dbm,则-90dbm大于阈值,因此第二量化步长是4db。
例如,阈值-109dbm,M=4db,N=2db。假设K=4,4个信道质量分别是:-135dbm,-125dbm,-90dbm,-138dbm。那么,参考信道质量是这4个信道质量中的最小值即-138dbm,则-138dbm小于阈值,因此第二量化步长是4db。
其中,该阈值、M和N中的任意的一个或多个值均可以是预定义的,例如通过协议预定义的,也可以是网络设备通过向终端发送信令配置给终端的。
作为一个示例,该阈值与用于恢复终端和网络设备之间的通信时设置的信道质量的门限值相等。需要说明的是,终端和网络设备之间的通信失败时/后,为了恢复终端与网络设备之间的通信,需要在候选参考信号资源集合中检测信道质量高于一个门限值的候选参考信号资源。该实施例中,所设置的阈值与该门限值相等。其中,本申请对该门限值的设置方式不进行限定,例如可以是预定义的例如协议预定义的,另外也可以是网络设备通过向终端发送信令配置的。其中,通信失败可以例如但不限于包括以下几种情况之一:①网络设备发送物理下行控制信道(physical downlink control channel,PDCCH)信息的波束和终端接收PDCCH信息的波束质量下降到足够低时发生通信失败,即用于传输PDCCH的波束对的质量下降到足够低时发生通信失败。质量下降到足够低可以例如但不限于体现为:终端接收的信号质量小于一个门限,或者终端在预定时间窗内无法接收到信号。②网络设备为终端配置与控制信道满足准共址QCL关系的参考信号资源,该参考信号资源的信道质量低于一个门限时,认为通信失败。通常该门限(例如上述①②中的门限)小于或等于恢复终端和网络设备之间的通 信时设置的信道质量的门限值。
作为一个示例,该阈值与用于判定通信失败时设置的信道质量的门限值相等。
方式2:若参考信道质量是K个信道质量中的最大值,则参考信道质量的量化值越大,第二量化步长越大。若参考信道质量是K个信道质量中的最小值,则参考信道质量的量化值越大,第二量化步长越小。
该方式中,每个参考信道质量的量化值对应一个第二量化步长,不同参考信道质量的量化值对应的第二量化步长不同。
方式3:若参考信道质量是K个信道质量中的最大值,则参考信道质量的量化值范围中的值越大,该参考信道质量的量化值范围对应的第二量化步长越大。
该方式中,每个参考信道质量的量化值范围对应一个第二量化步长,不同参考信道质量的量化值范围对应的第二量化步长不同。其中,第一量化范围[A,B]可以包括至少两个参考信道质量的量化值范围,每一个参考信道质量的量化值范围可以包括至少两个参考信道质量的量化值。不同参考信道质量的量化值范围之间无交集。
一、以映射关系是表格为例:
假设参考信道质量是RSRP,参考信道质量是K个信道质量中的最大值,且第一量化范围是区间[-140dbm,-44dbm],那么,参考信道质量的量化值范围与第二量化步长之间的映射关系可以如表1或表2所示。
表1
RSRP的量化值范围(单位:dbm) 第二量化步长(单位:db)
-140~-139 0.125
-138~-137 0.25
-136~-133 0.5
-132~-125 1
-124~-109 2
-108~-77 4
-76~-44 6
表2
RSRP的量化值范围(单位:dbm) 第二量化步长(单位:db)
-140~-125 1
-124~-109 2
-108~-77 4
-76~-44 6
其中,表1和表2的区别在于,表1中的第二量化步长可以大于1、等于1或小于1。表2中的第二量化步长均大于或等于1。
假设参考信道质量是RSRP,参考信道质量是K个信道质量中的最小值,且第一量化范围是区间[-140dbm,-44dbm],那么,参考信道质量的量化值范围与第二量化步长之间的映射关系可以如表3或表4所示。
表3
RSRP的量化值范围(单位:dbm) 第二量化步长(单位:db)
-140~-139 6
-138~-137 4
-136~-133 2
-132~-125 1
-124~-109 0.5
-108~-77 0.25
-76~-44 0.125
表4
RSRP的量化值范围(单位:dbm) 第二量化步长(单位:db)
-140~-125 6
-124~-109 4
-108~-77 2
-76~-44 1
其中,表3和表4的区别在于,表3中的第二量化步长可以大于1、等于1或小于1。表4中的第二量化步长均大于或等于1。表3所示的技术方案能够提高精确度,表4所示的技术方案可以使得终端实现简单。
二、以映射关系是公式为例:
当参考信道质量是K个信道质量中的最大值时,可以根据如下公式之一确定第二量化步长:△=(r-A)/2 N,△=ceil[(r-A)/2 N],△=floor[(r-A)/2 N],△=(r-A+1)/2 N,△=ceil[(r-A+1)/2 N],△=floor[(r-A+1)/2 N]。
当参考信道质量是K个信道质量中的最小值时,可以根据如下公式之一确定第二量化步长:△=(B-r)/2 N,△=ceil[(B-r)/2 N],△=floor[(B-r)/2 N],△=(B-r+1)/2 N,△=ceil[(B-r+1)/2 N],△=floor[(B-r+1)/2 N]。
其中,△表示第二量化步长,r表示参考信道质量的量化值,参考信道质量的量化值的取值范围,即上述第一量化范围是[A,B],N是非参考信道质量的量化比特数,N是大于等于1的整数;ceil()表示向上取整,floor()表示向下取整。
基于上述方式2或方式3,终端可以通过在预定义的表格中查找任意一个参考信道质量的量化值对应的第二量化步长。或者,终端可以通过预定义的公式计算得到任一个参考信道质量的量化值对应的第二量化步长。例如,若参考信道质量是K个信道质量中的最大值,参考信道质量的量化值是-135dbm,且终端和网络设备均使用表1所示的映射关系,则终端可以通过查询表1,确定参考信道质量的量化值-135dbm对应的第二量化步长是:-135dbm所在的参考信道质量的量化值范围(即-136~-133dbm)对应的第二量化步长即0.5db。又如,若参考信道质量是K个信道质量中的最小值,参考信道质量的量化值是-135dbm,且终端和网络设备均使用表3所示的映射关系,则终端可以通过查询表3,确定参考信道质量的量化值-135dbm对应的第二量化步长是:-135dbm所在的参考信道质量范围(即-136~-133dbm)对应的第二量化步长即2db。
S109:终端根据参考信道质量的量化值和第二量化步长对K个信道质量进行量化。
具体的,终端根据第二量化步长对K个信道质量中的非参考信道质量进行量化。
若参考信道质量是K个信道质量中的一个值,则S109具体可以是:终端根据第二量化步长对该K个信道质量中的除参考信道质量之外的K-1个信道质量进行量化。
若参考信道质量不是K个信道质量中的值,则S109具体可以是:终端根据第二量化步长对该K个信道质量进行量化。
若参考信道质量是K个信道质量中的两个值,例如最大值和最小值,则S109具体可以是:终端根据第二量化步长对该K个信道质量中的除参考信道质量之外的K-2个信道质量进行量化。
通常,非参考信道质量的量化比特数是固定值N,N是大于等于1的值,例如N=4。当然本申请不限于此。下文中均是以非参考信道质量的量化比特数是4为例进行说明的。
作为一个示例,根据参考信道质量的量化值和第二量化步长对K个信道质量进行量化,、可以包括如下实现方式:
实现方式1:根据参考信道质量的量化值r、第二量化步长△、以及非参考信道质量的量化比特数N,确定非参考信道质量的实际量化范围;然后在非参考信道质量的实际量化范围内,对K个信道质量中的非参考信道质量进行量化。
例如,若参考信道质量的量化值是K个信道质量中的最大值,则非参考信道质量的实际量化范围具体可以是[r-△*(2 N-1),r]或者[r-△*2 N,r-△]。若参考信道质量的量化值是K个信道质量中的最小值,则非参考信道质量的实际量化范围具体可以是[r,r+△*(2 N-1)]或者[r-△,r+△*2 N]。其中,△大于0。
实现方式2:根据参考信道质量r、第二量化步长△、非参考信道质量的量化比特数N,以及第二量化范围[C,D]确定非参考信道质量的实际量化范围;然后在实际量化范围内,对K个信道质量中的非参考信道质量进行量化。其中,第二量化范围[C,D]是预定义的一个范围。第二量化范围与第一量化范围可以相同,也可以不相同。C小于D。
例如,若参考信道质量的量化值是K个信道质量中的最大值,则非参考信道质量的实际量化范围具体可以是[max{r-△*(2 N-1),C},r]。若参考信道质量的量化值是K个信道质量中的最小值,则非参考信道质量的实际量化范围具体可以是[r,min{r+△*(2 N-1),D}]。
实现方式3:若参考信道质量是K个信道质量中的两个值,则这两个值通常用于确定非参考信道质量的实际量化范围;然后在实际量化范围内,基于用于确定第二量化步长的参考信道质量,对该K个信道质量中的除参考信道质量之外的K-2个信道质量进行量化。
例如,若参考信道质量是K个信道质量中的最小值E和最大值F,E小于F,则非参考信道质量的实际量化范围具体可以是[E,F]。
另外,实现方式3也可以与实现方式1或实现方式2结合使用。
例如,若实现方式3与实现方式1结合,则当用于确定第二量化步长的是K个信道质量中的最大值时,非参考信道质量的实际量化范围具体可以是[max{r-△*(2 N-1),E},min{r,F}];当用于确定第二量化步长的是K个信道质量中的最小值时,非参考 信道质量的实际量化范围具体可以是[max{r,E},min{r+△*(2 N-1),F}]。
又如,若实现方式3与实现方式2结合,则当用于确定第二量化步长的是K个信道质量中的最大值时,非参考信道质量的实际量化范围具体可以是[max{r-△*(2 N-1),E,C},min{r,F}];当用于确定第二量化步长的是K个信道质量中的最小值时,非参考信道质量的实际量化范围具体可以是[max{r,E},min{r+△*(2 N-1),F,D}]。
下面通过具体的示例对上述步骤进行说明:
假设K=4,4个信道质量分别是:-135dbm、-112dbm、-146dbm、-138dbm,第二量化范围是区间[-140dbm,-44dbm],参考信道质量的量化值与第二量化步长之间的映射关系如上述表2所示。那么:
示例1,参考信道质量可以是这4个信道质量中的最大值即-112dbm,该情况下,非参考信道质量的实际量化范围可以是区间[-140dbm,-112dbm],则参考信道质量-112bm的量化值是-112dbm。参考表2可知,第二量化步长是2db。由此可知,非信道质量可能的量化值构成的集合是{-112dbm,-114dbm,-116dbm……-140dbm},如表5所示。

示例2:参考信道质量可以是这4个信道质量中的最小值即-146dbm,则参考信道质量-146dbm的量化值是-140dbm。参考表2可知,参考信道质量的量化值-140dbm对应的第二量化步长是1db。由此可知,非信道质量可能的量化值构成的集合是{-140dbm,-139dbm,-138dbm,……-125dbm},非参考信道质量的实际量化范围可以是区间[-140dbm,-125dbm],如表6所示。

在本申请的一些实施例中,当非参考信道质量量化后得到的状态不足N比特时,可以循环重复或者补充特殊状态值(例如0)以保证非参考信道质量的量化比特数是N。 例如,假设非参考信道质量的实际量化范围是[-140dbm,-138dbm],第二量化步长是1db,则仅需2比特即可指示非参考信道质量所有可能的量化值,共需要6个比特,可以分别使用状态00、01、10来指示该范围内的量化值。那么,实际传输时,可以使用000110以及补充的状态位000000来表示该范围内的各量化值。或者,可以使用000110以及循环重复的000110来表示该范围内的各量化值。
S110:终端生成并向网络设备发送信道质量信息,其中,信道质量信息用于指示参考信道质量,以及K个信道质量量化后得到的量化值。具体的,信道质量信息用于指示S107中对参考信道质量进行量化后得到的量化值,以及S109中对K个信道质量中的非参考信道质量进行量化后得到的量化值。
作为一个示例,信道质量信息可以包括:参考信道质量的量化值的索引,以及K个信道质量中的每一非参考信道质量的量化值的索引。其中参考信道质量的量化值的索引用于指示参考信道质量的量化值,非参考信道质量的量化值的索引用于指示非参考信道质量的量化值。
例如,若参考信道质量是K个信道质量中的最大值,则第i个参考信道质量的量化值的索引所指示的信道质量的量化值是max{r-i*△,A},i是[0,2 N-1]中的整数,N是非参考信道质量的量化比特数,N是大于等于1的整数。其中,△表示第二量化步长,△大于0,r表示参考信道质量的量化值。或者,非参考信道质量的量化值的索引与非参考信道质量的量化值之间的对应关系可以如表7所示,其中,表7中是以非参考信道质量的量化比特数是4为例进行说明的。

又如,若参考信道质量是K个信道质量中的最小值,则第i个参考信道质量的量化值的索引所指示的信道质量的量化值是min{r+i*△,B}。或者,非参考信道质量的量化值的索引与非参考信道质量的量化值之间的对应关系可以如表8所示。其中,表8中是以非参考信道质量的量化比特数是4为例进行说明的。

例如,若参考信道质量是K个信道质量中的最大值,则差分信道质量的量化值的索引与差分信道质量的量化值之间的对应关系可以如表9所示。其中,表9中是以非参考信道质量的量化比特数是4为例进行说明的。

基于上述任一示例,信道质量信息还可以包括:K个信道质量中每一非参考信道质量对应的参考信号资源索引。
终端可以通过物理上行链路控制信道(physical uplink control channel,PUCCH)或物理上行共享信道(physical uplink shared channel,PUSCH)向网络设备发送信道质量信息。
在一些实现方式中,若参考信道质量是网络设备向终端配置的,则在S110中,信道质量信息也可以不用于指示参考信道质量。
S111:网络设备接收终端发送的信道质量信息,并根据参考信道质量的量化值的索引确定参考信道质量的量化值。
S112:网络设备根据参考信道质量的量化值确定第二量化步长。
网络设备中可以预先存储各参考信道质量的量化值与第二量化步长之间的映射关系。关于参考信道质量的量化值与第二量化步长之间的映射关系,以及如何根据参考信道质量的量化值确定第二量化步长,均可以参考上文,此处不再赘述。
S113:网络设备根据参考信号的量化值、第二量化步长,以及用于指示K个信道质量中的非参考信道质量的量化值的信息,确定K个信道质量中的非参考信道质量的量化值。
若用于指示K个信道质量中的非参考信道质量的量化值的信息是非参考信道质量的量化值的索引,如表7或表8所示,则相应的,在S113中,网络设备可以根据非参 考信道质量的量化值的索引与非参考信道质量的量化值之间的对应关系,如表7或表8所示,确定K个信道质量中的每一非参考信道质量的量化值。例如,参见表5,假设参考信道质量的量化值是-112dbm,K个信道质量中的非参考信道质量的量化值分别是-134dbm、-140dbm和-138dbm,那么,终端可以基于表7得到这3个非参考信道质量的量化值的索引,同理,在S113中,网络设备可以基于表7得到这3个非参考信道质量的量化值的索引所指示的非参考信道质量的量化值,即得到-134dbm、-140dbm和-138dbm。
若用于指示K个信道质量中的非参考信道质量的量化值的信息是差分信道质量的量化值的索引,如表9或表10所示,则相应的,在S113中,网络设备可以根据差分信道质量的量化值的索引与差分信道质量的量化值之间的对应关系,如表9或表10所示,确定信道质量信息中包括的每一差分信道质量的量化值索引所指示的差分信道质量的量化值,然后基于参考信道质量的量化值与所确定的每一差分信道质量的量化值,确定K个信道质量中的每一非参考信道质量的量化值。例如,参见表5,假设参考信道质量的量化值是-112dbm,K个信道质量中的非参考信道质量的量化值分别是-134dbm、-140dbm和-138dbm,那么,终端可以先获取这3个非参考信道质量的量化值相对于-112dbm的差分信道质量的量化值,即:32db、28db和26db;然后,基于表9得到这3个差分信道质量的量化值的索引,同理,在S113中,网络设备可以基于表9得到这3个差分信道质量的量化值的索引所指示的非参考信道质量的量化值,即得到32db、28db和26db;接着,基于参考信道质量的量化值是-112db和这3个差分信道质量的量化值32db、28db和26db,得到K个信道质量中的非参考信道质量的量化值,即得到-134dbm、-140dbm和-138dbm。
在S113之后,网络设备可以根据K个信道质量的量化值,从K个波束对中选择出一个波束对,并指示给终端。后续,网络设备使用该波束对中的发送波束发送信息,终端使用该波束对中的接收波束接收该信息。其中,该信息例如但不限于包括以下信息中的至少一种:控制信道信息、数据信道信息或者探测信号等。
本实施例提供的传输信道质量的方法中,在终端需要上报多个信道质量时,基于参考信道质量确定对非参考信道质量进行量化的量化步长。这样,根据参考信道质量和量化步长所确定的非参考信道质量的量化值的取值范围不是固定不变的,因此,通过合理设置对非参考信道质量进行量化时的量化步长,可以调整非参考信道质量的量化值的取值范围,从而有助于提高系统整体性能增益。
