Description

一种信道质量上报方法及装置 技术领域
本申请涉及通信技术领域,尤其涉及一种信道质量上报方法及装置。
背景技术
机器类型通信(Machine Type Communication,MTC)或窄带物联网(Narrow Band Internet of Thing,NB-IoT)有别于传统长期演进(Long Term Evolution,LTE)通信,其不追求数据传输速率、多频段、多天线、全双工传输,而是追求较长的终端电池的使用时间,较低廉的终端成本,即要求终端能够实现低功耗(Low power consumption)、低成本(Low cost)。此外,考虑到MTC类型的终端的应用场景,例如水表、电表等,终端的信号覆盖强度无法满足信号接收要求,因此对MTC进行增强,使基站和终端能够支持扩展覆盖或增强覆盖(enhanced coverage)或覆盖增强(coverage enhancement),目前实现扩展覆盖的主要方法是重复多次发送上行或下行信号,通过多次接收合并实现提高数据接收成功率的目的。再者,在MTC或NB-IoT的应用场景中,其数据传输的特点是,数据量较小,且数据到达时间不确定。例如,网络侧呼叫终端上报数据,或是网络侧向终端下达控制指令等。现有技术中,为了传输数据,需要建立起基站与终端之间的无线连接,而建立该无线连接需要一定的信令开销,如果只是为了传输较小的数据,沿用现有技术中的连接建立流程,会使得无线资源的利用效率降低,大量资源用于连接建立的流程,少量资源用于数据传输。再者,对于传统终端(如日常所用的智能手机),其常常有小数据包需要与网络进行交互,若沿用现有技术中的连接建立流程,资源利用率低。
为此,在改进的方案中,上行数据最早可以在随机接入过程中的Msg3进行传输,下行数据最早可以在随机接入过程中的Msg4进行传输。
基站在调度终端进行上下行数据传输时,如果能够获取到终端的下行信道质量,则基站可以更好地调度接入网设备进行下行数据传输。例如,在MTC或NB-IoT中,基站根据下行信道质量可以更精确的确定调度下行数据传输的重复次数,使得终端刚好能够成功接收到下行数据,又不会有过多的无效的重复传输,如终端重复接收M次下行数据即可正确解出下行数据,如果基站重复发送下行数据大于M次,则多于M次的重复传输会造成资源浪费,如果基站重复发送下行数据小于M次,则终端无法成功接收到下行数据。根据上面所述,若要高效地调度下行数据(例如,Msg4这个下行数据),基站可以在调度下行数据之前获取终端的下行信道质量(例如,通过Msg3获取到下行信道质量)。这在NB-IOT中已经实现,即在Msg3中向基站上报信道质量指示窄带物理下行控制信道(Channel quality indicator narrowband physical downlink control channel,cqi-NPDCCH),用于指示服务小区的下行信道质量。在NB-IOT中,该指示信息(即cqi-NPDCCH)直接引入至以下Msg3中:
1),RRCConnectionReestablishmentRequest(无线资源控制(radio resource control,RRC)连接重建立请求);
2),RRCConnectionRequest(RRC连接请求);
3),RRCConnectionResumeRequest(RRC连接恢复请求);
4),RRCEarlyDataRequest(RRC早传数据请求)。
当前在NB-IOT中,支持长的cqi-NPDCCH和短的cqi-NPDCCH上报,其中长的为4bits,短的为2bits。由于NB-IOT中,上述三条消息中有较多冗余比特,所以可以直接引入。
而在MTC或LTE中,上述第一条消息只有2个冗余比特,上述第二条、第三条消息只有1个冗余比特,如此,将难以在上述三条消息中指示下行信道质量。

终端是一种具有无线收发功能的设备,终端可以部署在陆地上,包括室内或室外、手持或车载;也可以部署在水面上(如轮船等);还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端、增强现实(augmented reality,AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端,以及还可以包括用户设备(user equipment,UE)等。
接入网设备,也可以称为无线接入网(radio access network,RAN)设备,是一种为终端提供无线通信功能的设备。接入网设备例如包括但不限于:第五代(5th generation,5G)中的下一代基站(g nodeB,gNB)、演进型节点B(evolved node B,eNB)、无线网络控制器(radio network controller,RNC)、节点B(node B,NB)、基站控制器(base station controller,BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如,home evolved nodeB,或home node B,HNB)、基带单元(baseBand  unit,BBU)、传输点(transmitting and receiving point,TRP)、发射点(transmitting point,TP)、移动交换中心等。
基于图1所示的应用场景,本申请提供一种信道质量上报方法,该方法是在Msg3的媒体接入控制(medium access control,MAC)协议数据单元(protocol data unit,PDU)的MAC PDU子头中指示下行信道质量。由于MAC PDU子头的某些域目前未使用,或者是某些域的部分比特信息处于未定义取值,或者是某些域的部分比特位在Msg3中并不使用,因此本申请将利用这些未使用的域、或处于未定义取值的比特信息、或在Msg3中未使用的比特信息指示下行信道质量,以实现在Msg3指示下行信道质量,因而可以解决背景技术所提到的MTC或LTE难以在Msg3指示下行信道质量的问题。需要说明的是,本申请方法同样也可以适用于NB-IoT场景。
在介绍本申请之前,首先对现有技术定义的一个MAC PDU的数据结构进行介绍说明。
一个MAC PDU由一个MAC PDU头、0个或多个MAC业务数据单元(service data unit,SDU)以及0个或多个MAC控制单元(Control Element,CE)组成。可选地,一个MAC PDU还包括填补比特(Padding)。其中,MAC PDU头和MAC SDU的大小(size)都是变化。
其中,一个MAC PDU头由一个或多个MAC PDU子头组成,一个MAC PDU子头对应一个MAC SDU、或对应一个MAC CE、或对应Padding。
一个MAC PDU子头由保留(reversed,R)域、F2域、扩展(Extension,E)域、逻辑信道标识(Logical Channel Identity,LCID)域、(R域、R域、扩展LCID(Extension,eLCID)域)、(格式(format,F)域)、长度(length,L)域组成。其中,(R域、R域、eLCID域)是可选的,有的MAC PDU子头包括R域、R域和eLCID域,有的MAC PDU子头不包括R域、R域和eLCID域。同样的,F域也是可选的。
目前,标准定义了4种MAC PDU子头的格式,分别如图2a-图2d所示。其中,图2a为包含7比特的L域的MAC PDU子头示意图,图2b为包含15比特的L域的MAC PDU子头示意图,图2c为包含16比特的L域的MAC PDU子头示意图,图2d为无L域的MAC PDU子头示意图。
下面对上述MAC PDU子头中各个域的含义和取值范围进行说明。
(1)、LCID域
LCID域为5比特,用于标识逻辑信道或MAC CE或Padding,对于上行(uplink),其取值如下表1所示,该表1即为3GPP TS 36.321 v15.3.0中定义的Table 6.2.1-2。
表1上行共享信道LCID域的值(Values of LCID for UL-SCH)

Figure PCTCN2018125813-appb-000005
针对上述表1,需要关注以下几点:
第一,如果SIB2指示unicastFreqHoppingInd,则支持单播跳频的带宽减少和低复杂度(Bandwidth reduced and Low complexity,BL)终端或支持单播跳频的处于增强覆盖下的终端,将使用LCID的取值为“01100”来指示CCCH。其实质是终端使用LCID的取值为“01100”来指示CCCH,并且指示该终端支持单播跳频的能力。
如果SIB2没有指示unicastFreqHoppingInd,或终端不支持支持单播跳频,或终端不处于增强覆盖下,如果该终端是0类(Category 0)终端,则该终端使用LCID“01011”来指示CCCH。其实质是终端使用LCID的取值为“01011”来指示CCCH,并且指示该终端不支持单播跳频的能力、不处于增强覆盖下、且该终端是Category 0终端。
其中,上述unicastFreqHoppingInd用于让终端指示跳频能力。
否则,终端使用“00000”来指示CCCH。
或者,也可以理解为,LCID域的取值为“00000”时,指示的信息为:CCCH。
LCID域的取值为“01011”时,指示的信息为:CCCH和终端为0类(Category 0)终端。
LCID域的取值为“01100”时,指示的信息为:CCCH和终端支持单播跳频。
第二,LCID取值为01110、01111、10001,其对应的含义是保留的,也即目前没有定义LCID取值为01110、01111、10001时的含义。
第三,LCID取值为10000时,表明R域、R域、eLCID域包含于MAC PDU子头中。
(2)、eLCID域
eLCID域:为6比特,用于标识逻辑信道,对于上行(uplink),其取值如下表2所示,该表2即为3GPP TS 36.321 v15.3.0中定义的Table 6.2.1-2a。
表2 eLCID域的值(Values of eLCID for UL-SCH)
Figure PCTCN2018125813-appb-000006
(3)、L域
L域用于指示对应的MAC SDU的长度,或者指示大小变化的MAC CE的长度。L域可为7bits、15bits、或16bits。L域的大小是由F域和F2域共同指示的。
(4)、E域
E域指示该MAC PDU子头之后是否还有MAC PDU子头。
(5)、F域和F2域
F2域用于指示L域的大小,如果MAC SDU或MAC CE的大小大于32767字节,且该MAC PDU子头不是最后一个子头,则F2设置为1,否则,设置为0。
F域用于指示L域的大小,如果F域存在且MAC SDU或MAC CE的大小小于128字节,则F设置为0,否则设置为1。
因此,当F2域取值为0,F域取值为0,则指示的MAC PDU子头的结构如图2(a)所示;当F2域取值为0,F域取值为1,则指示的MAC PDU子头的结构如图2(b)所示;当F2域取值为1,此时没有F域,则指示的MAC PDU子头的结构如图2(c)所示。具体可参考如下表3,为F域、F2域的取值及L域大小之间的关系表。

以上是现有技术对于MAC PDU及MAC PDU子头的简单介绍,本申请将基于该示例,对本申请提供的下行信道质量的上报方法进行说明。需要说明的是,本申请可以应用于上述示例,也可以应用于对上述MAC PDU子头进行修改后的新的MAC PDU 子头(比如在上述现有技术的MAC PDU子头中增加一行,即增加一个字节),上述具体示例并不构成对本申请应用范围的限定。
需要说明的是,由于本申请中将可能会使用上述MAC PDU子头中的第一字节或第一行的最左侧(leftmost)或最高位(most significant),由于该保留域使用之后将不适合再称为保留域,因此本申请中将该保留域称为第一域,即本申请中的第一域指的是MAC PDU子头中第一字节或第一行的最左侧(leftmost)或最高位(most significant)的一个比特域或所述第一域为保留域(R)。
如图3所示,为本申请提供的一种下行信道质量上报方法示意图,该方法包括以下步骤:
步骤302,终端生成MAC PDU,所述MAC PDU包括MAC PDU头,所述MAC PDU头用于指示下行信道质量。
在一种可能的实施方式中,可以由终端的MAC实体从复用和级联实体(Multiplexing and assembly entity)获取MAC PDU。
比如,下行信道质量比如可以是下行控制信道的重复次数(repetition number)(例如,要求误块率(BLER)为1%时,终端解码机器类型通信物理下行控制信道(MTC Physical Downlink Control Channel,MPDCCH)的重复次数),或者还可以是下行控制信道的聚合等级(aggregation level)(例如,要求误块率(BLER)为1%时,终端解码MPDCCH的聚合等级)。
步骤303,终端向接入网设备发送所述MAC PDU。相应地,接入网设备可以接收到该MAC PDU。
步骤304,接入网设备根据所述MAC PDU,确定下行信道质量。
即接入网设备可以根据MAC PDU的MAC PDU头确定下行信道质量。
基于上述方案,本申请在Msg3的MAC PDU的MAC PDU头中指示了下行信道质量,因而实现了在Msg3中指示下行信道质量,进而接入网设备可以根据接收到的下行信道质量更好地实现调度下行数据传输之目的,如调度Msg4这个下行数据,可以减少资源开销,降低终端功耗。
例如,在MTC或NB-IoT中,接入网设备根据下行信道质量可以更精确的确定调度下行数据传输的重复次数,使得终端刚好能够成功接收到下行数据,又不会有过多的无效的重复传输,如终端重复接收M次下行数据即可正确解出下行数据,如果接入网设备重复发送下行数据大于M次,则多于M次的重复传输会造成资源浪费,如果接入网设备重复发送下行数据小于M次,则终端无法成功接收到下行数据。基于该方案,接入网设备可以在调度下行数据之前,通过Msg3获取终端的下行信道质量,从而接入网设备可以高效地调度下行数据(例如,Msg4这个下行数据)。
可选的,在上述步骤302之前,还可以包括以下步骤301。
步骤301,接入网设备向终端发送指示信息。相应地,终端可以接收到该指示信息。
该指示信息用于指示允许终端在Msg3上报下行信道质量。即接入网设备指示终端具备上报下行信道质量的资格。
作为一种实现方式,该指示信息可以是携带于系统消息(System Information)发送至终端的。
作为一种实施方式,可以利用第一域和LCID域指示下行信道质量。例如,如前述介绍,MAC PDU子头的保留域(第一域)目前还没有定义,LCID域的部分取值也未定义(即保留),在Msg3中LCID域的部分取值未使用,因此可以利用第一域和LCID域指示下行信道质量。
作为一种实施方式,可以利用F域和F2域的取值组合来指示下行信道质量。例如,在一些场景中,Msg3携带的数据量较少,一般不会超过1000比特,因此Msg3可以采用如图2a所示的MAC PDU子头结构,因而F域和F2域的取值始终均为0,因此也可以利用F域和F2域的取值组合来指示下行信道质量。
综上,本申请可以使用MAC PDU子头中的第一域、F域、F2域和LCID域中的一个或多个域用于指示所述下行信道质量。此外,本申请还可以通过扩展MAC PDU子头的域来实现指示下行信道质量之目的。
为方便说明,本申请后续将使用quality value来表示下行信道质量,比如,quality value1用于表示第一下行信道质量,quality value2用于表示第二下行信道质量,quality value3用于表示第三下行信道质量,quality value4用于表示第四下行信道质量,quality value5用于表示第五下行信道质量,quality value6用于表示第六下行信道质量,quality value7用于表示第七下行信道质量,以此类推。一个quality value可以表示一个或多个取值,或者表示一个取值范围,后面会具体说明。
下面给出不同的实现方法,以实现在MAC PDU子头指示下行信道质量。
方法1,MAC PDU子头中的第二域的取值和LCID域的取值用于指示下行信道质量,第二域为第一域、或为F域、或为F2域。
即,使用第二域的取值和LCID域的取值联合指示下行信道质量,以及还指示CCCH。下面给出三种方法进行具体说明。
方法1.1,所述MAC PDU子头中的所述第二域的取值和所述LCID域的取值用于指示第一信息和所述下行信道质量;其中,所述第一信息为CCCH,CCCH和所述终端支持单播跳频,CCCH和所述终端为0类(Category 0)终端中的任意一个,或者,所述第一信息是LCID为00000时对应的CCCH,LCID为01011时对应的CCCH,LCID为01100时对应的CCCH中的任意一个。
结合表1,下面给出一种该方法1.1的具体示例,如表4所示。
表4第二域的取值和LCID域的取值用于指示的内容
Figure PCTCN2018125813-appb-000008
根据表1,由于LCID域的取值为01110、01111和10001时,没有给出相应的定义,即01110、01111和10001均为保留的取值,因此该方法基于该特征,使用LCID 域的这三个取值和第二域的取值相结合,来指示第一信息和下行信道质量。
在可能的实施方式中,可以采用表1中第二行至第七行中的一行或多行来指示下行信道质量。
需要说明的是,此时表1中原来的LCID为00000时指示的CCCH、LCID为01011指示的CCCH、LCID为01100指示的CCCH的含义仍然可以适用。或者理解为,基于本申请既可以使用LCID分别为00000、01011和01100来指示CCCH,也可以使用LCID为01110、01111和10001时结合第二域来指示第一信息和下行信道质量。
下面分别对表4中的quality value、CCCH以及表4进行解释说明。
第一,对表4中的quality value的解释说明。
表4中的quality value1至quality value6中的任一quality value可以是一个或多个取值,比如可以是下行控制信道的重复次数(repetition number)(例如,要求误块率(BLER)为1%时,终端解码MPDCCH的重复次数),或者还可以是下行控制信道的聚合等级(aggregation level)(例如,要求误块率(BLER)为1%时,终端解码MPDCCH的聚合等级)。
表4中的quality value1至quality value6中的任一quality value还可以是一个取值范围,比如可以是下行控制信道的重复次数的范围(例如,要求块误块率为1%时,终端解码MPDCCH的重复次数的范围),或者还可以是下行控制信道的聚合等级的范围(如要求误块率为1%时,终端解码MPDCCH的聚合等级的范围)。
可选地,上述“终端解码MPDCCH”还可以是“终端解码假设的(hypothetical)MPDCCH”。
表4中的quality value1至quality value6中的任一quality value还可以是一个取值范围或取值,即quality value1至quality value6中的部分quality value为取值,部分quality value为取值范围,即该方法是前述两种方法的结合。
下面以表4中的quality value1至quality value6中的任一quality value是一个取值范围(例如,可以是重复次数范围或聚合等级范围)为例进行说明。比如quality value与取值范围的对应关系如下表5-1所示。
表5-1 quality value与取值范围的对应关系
quality value 取值范围
quality value1 X1≤quality value1<X2
quality value2 X2≤quality value2<X3
quality value3 X3≤quality value3<X4
quality value4 X4≤quality value4<X5
quality value5 X5≤quality value5<X6
quality value6 X6≤quality value6<X7
其中,0≤X1<X2<X3<X4<X5<X6<X7。
在又一个示例中,以表4中的quality value1至quality value6中的任一quality value是一个取值范围(例如,可以是重复次数范围或聚合等级范围)为例进行说明。比如quality value与取值范围的对应关系如下表5-2所示。
表5-2 quality value与取值范围的对应关系
quality value 取值范围
quality value1 quality value1<X1
quality value2 X1≤quality value2<X2
quality value3 X2≤quality value3<X3
quality value4 X3≤quality value4<X4
quality value5 X4≤quality value5<X5
quality value6 X5≤quality value6
其中,0<X1<X2<X3<X4<X5。
本申请对于quality value与取值范围的对应关系中的取值范围的划分方法没有具体限制。
在又一个示例中,以表4中的quality value1至quality value6中的任一quality value是一个或多个取值(例如,可以是重复次数或聚合等级)为例进行说明。比如quality value与取值的对应关系如下表6所示。
表6 quality value与取值的对应关系
quality value 取值
quality value1 {a1,a2,……,aA}
quality value2 {b1,b2,……,bB}
quality value3 {c1,c2,……,cC}
quality value4 {d1,d2,……,dD}
quality value5 {e1,e2,……,eE}
quality value6 {f1,f2,……,fF}
如表6所示,quality value1对应的取值包括a1,a2,……aA,其中A为正整数;quality value2对应的取值包括b1,b2,……bB,其中B为正整数;quality value3对应的取值包括c1,c2,……,cC,其中C为正整数;quality value4对应的取值包括d1,d2,……,dD,其中D为正整数;quality value5对应的取值包括e1,e2,……,eE,其中E为正整数;quality value6对应的取值包括f1,f2,……,fF,其中F为正整数。每个quality value对应的取值可以是一个或多个。
需要说明的是,上述表4是协议预定义的,或者是预配置在终端及接入网设备上的,即上述表4是终端和接入网设备均预先获取的可存储于本地的表。
同样的,对于上述quality value的理解,也可以是协议预定义或者是预配置在终端及接入网设备的。在具体实现中,可以采用上述表5-1、或表5-2、或表6中的任一方式预定义,当然上述表5-1、表5-2、表6只是作为示例,也可以是其他方式的预定义。
本发明中所涉及的表格,不限制于使用整个表格,使用个整个表格中的一行或多行的方法也在本发明的保护范围之内。
第二,对表4中的CCCH的解释说明。
根据表1所示的方案,可以看出MAC PDU子头可以指示三种CCCH,分别是LCID为00000时指示的CCCH、LCID为01011指示的CCCH、LCID为01100指示的CCCH,而本申请的该方法1.1中,仅可以指示一种CCCH,该CCCH需要进行预定义,比如预定义该CCCH是表1中LCID为00000时指示的CCCH,或者预定义该CCCH是表1中LCID为01011时指示的CCCH,或者预定义该CCCH是表1中LCID为01100时指示的CCCH。
第三,对表4中第二域和LCID域的解释说明。
该表4指示了如何将第二域和LCID域相结合,以指示下行信道质量、第一信息。具体地:
比如,当第二域的取值为0,LCID域的取值为01110时,则指示quality value1和第一信息。再比如,当第二域的取值为1,LCID域的取值为01110时,则指示quality value4和第一信息,等等,不再一一例举说明。
针对该表4,需要关注以下几点:
1),第二域的取值、LCID域的取值与指示的下行信道质量的关系是预先定义的,但上述表4并不是唯一的预定义方式。
比如,可以将第二域的取值为0,LCID的取值为01110对应的quality value1,与第二域的取值为0,LCID的取值为01111对应的quality value2调换,即第二域的取值为0,LCID的取值为01110时指示quality value2,第二域的取值为0,LCID的取值为01111时指示quality value1。即上述表4中的quality value1至quality value6相互之间可以任意互换位置。
再比如,也还可以将上述表4中的LCID的6种取值相互之间可以任意互换位置。
需要说明的是,一旦选择一种定义方式,则将以该方式作为预定义的对应关系,在具体使用中将只能参照这一种对应关系。
2),指示的第一信息是预定义的,一旦预定义了其含义,则后续将只能指示该第一信息。
3),quality value可以是一个或多个取值,也可以是取值范围,一旦预定义,则后续将只能指示对应的含义。
以上是对方法1.1中的作为示例的表4的解释说明。下面以表4为例,介绍说明终端如何使用该表4,向接入网设备上报下行信道质量,即终端如何使用上述表4来执行上述步骤302。
假设终端测量得到的下行信道质量的取值为下行控制信道的重复次数,上述表4定义的quality value对应下行控制信道的重复次数的取值范围。
比如,终端测量得到的下行信道质量的取值为M(即下行控制信道的重复次数等于M),则终端查找上述表4,确定下行控制信道的重复次数取值为M时对应的第二域的取值和LCID域的取值,假设下行控制信道的重复次数取值为M属于quality valueN对应的取值范围,则终端确定quality valueN对应的第二域的取值和LCID域的取值。比如,M=5,且下行控制信道的重复次数取值为5属于quality value4对应的取值范围,则根据上述表4,确定第二域为1,LCID域为01110,即终端将会在MAC PDU头的MAC PDU子头的第二域填充1,在LCID域填充01110。
相对应的,接入网设备接收到终端发送的Msg3之后,获取MAC PDU头的MAC PDU子头中各个域的信息,接入网设备获取到第二域的取值和LCID域的取值(比如第二域的取值为1,LCID域的取值为01110),接入网设备可以通过查找上述表4,确定终端上报的下行信道质量的取值和第一信息(比如确定下行信道质量的取值是在quality value4对应的取值范围内,以及确定和第一信息)。即基于该示例,接入网设备并不能准确获知终端测量到的下行信道质量的取值,而只能获知终端测量到的下行信道质量对应的取值范围。
当然,若希望接入网设备可以准确获知终端测量到的下行信道质量的取值,则可以将上述表4中的各个quality value分别对应一个取值,这种方式可以使得接入网设备通过Msg3准确获知终端测量得到的下行信道质量的取值。但基于该方法1.1,只能预定义最多6种具体的下行信道质量的取值,比较受限,因此一般情形下,若接入网设备不要求获知准确的下行信道质量的取值,则可以将上述quality value均对应一个取值范围。
以下方法1.2和方法1.3,与上述方法1.1类似,只是方法1.2可以指示2个CCCH和3个quality value,方法1.3可以指示3个CCCH和2个quality value。下面分别说明。
方法1.2,MAC PDU子头中的第二域的取值和LCID域的取值用于指示第一信息和下行信道质量,或用于指示第二信息和下行信道质量;其中,第一信息、第二信息为CCCH,CCCH和终端支持单播跳频,CCCH和终端为0类(Category 0)终端中的任意两个,或者,第一信息、第二信息是LCID为00000时对应的CCCH,LCID为01011时对应的CCCH,LCID为01100时对应的CCCH中的任意两个。
结合表1,下面给出一种该方法1.2的具体示例,如表7所示。
表7第二域的取值和LCID域的取值指示的内容
Figure PCTCN2018125813-appb-000009
该表7中的第一信息、第二信息共有6种不同的预定义方式,分别如下:
1)、第一信息:CCCH;第二信息:CCCH和终端支持单播跳频;
2)、第一信息:CCCH;第二信息:CCCH和终端为0类(Category 0)终端;
3)、第一信息:CCCH和终端支持单播跳频;第二信息:CCCH;
4)、第一信息:CCCH和终端支持单播跳频;第二信息:CCCH和终端为0类(Category 0)终端;
5)、第一信息:CCCH和终端为0类(Category 0)终端;第二信息:CCCH;
6)、第一信息:CCCH和终端为0类(Category 0)终端;第二信息:CCCH和 终端支持单播跳频。
实际应用中,可以选择上述任一种作为预定义的第一信息和第二信息。
或者理解为,该表7中的第一信息、第二信息共有6种不同的预定义方式,分别如下:
1)、第一信息:LCID为00000时对应的CCCH;第二信息:LCID为01011时对应的CCCH;
2)、第一信息:LCID为00000时对应的CCCH;第二信息:LCID为01100时对应的CCCH;
3)、第一信息:LCID为01011时对应的CCCH;第二信息:LCID为00000时对应的CCCH;
4)、第一信息:LCID为01011时对应的CCCH;第二信息:LCID为01100时对应的CCCH;
5)、第一信息:LCID为01100时对应的CCCH;第二信息:LCID为00000时对应的CCCH;
6)、第一信息:LCID为01100时对应的CCCH;第二信息:LCID为01011时对应的CCCH。
实际应用中,可以选择上述任一种作为预定义的第一信息和第二信息。
进一步的,针对表7中的quality value1至quality value3,其可以采用类似于上述表5-1、或表5-2、或表6任一所示的预定义方式,可参考前述方式实现,不再赘述。
因此,该方法1.2中,通过第二域和LCID域,可以指示2个信息(第一信息或第二信息)和3个quality value,每个quality value对应一个取值范围或至少一个取值。
以上是对方法1.2中的作为示例的表7的解释说明。下面以表7为例,介绍说明终端如何使用该表7,向接入网设备上报下行信道质量,即终端如何使用上述表7来执行上述步骤302。
假设终端测量得到的下行信道质量的取值为下行控制信道的重复次数,上述表7定义的quality value对应下行控制信道的重复次数的取值范围。
比如,终端测量得到的下行信道质量的取值为M(即下行控制信道的重复次数等于M),且该终端的类型为第一信息,则终端查找上述表7,确定下行控制信道的重复次数取值为M时对应的第二域的取值和LCID域的取值,假设下行控制信道的重复次数取值为M属于quality valueN对应的取值范围,则终端确定quality valueN对应的第二域的取值和LCID域的取值。比如,M=5,且下行控制信道的重复次数取值为5属于quality value2对应的取值范围,则根据上述表7,确定第二域为0,LCID域为10001,即终端将会在MAC PDU头的MAC PDU子头的第二域填充0,在LCID域填充10001。
相对应的,接入网设备接收到终端发送的Msg3之后,获取MAC PDU头的MAC PDU子头中各个域的信息,接入网设备获取到第二域的取值和LCID域的取值(比如第二域的取值为0,LCID域的取值为10001),接入网设备可以通过查找上述表7,确定终端上报的下行信道质量的取值和信息(比如确定下行信道质量的取值是在quality value2对应的取值范围内,且确定为第一信息)。基于该示例,接入网设备并不能准确获知终端测量到的下行信道质量的取值,而只能获知终端测量到的下行信道质量对应的取值范围。进一步的,相较于方法1.1,该方法1.2中终端对应的信息可以 有两种(即第一信息或第二信息)。
当然,若希望接入网设备可以准确获知终端测量到的下行信道质量的取值,则可以将上述表7中的各个quality value分别对应一个取值,这种方式可以使得接入网设备通过Msg3准确获知终端测量得到的下行信道质量的取值。但基于该方法1.2,只能预定义最多3种具体的下行信道质量的取值,比较受限,因此一般情形下,若接入网设备不要求获知准确的下行信道质量的取值,则可以将上述quality value均对应一个取值范围。
方法1.3,MAC PDU子头中的第二域的取值和LCID域的取值用于指示第一信息和下行信道质量,或用于指示第二信息和下行信道质量,或用于指示第三信息和下行信道质量;其中,第一信息、第二信息、第三信息分别为CCCH,CCCH和终端支持单播跳频,CCCH和终端为0类(Category 0)终端中的一个,或者,第一信息、第二信息、第三信息分别是LCID为00000时对应的CCCH,LCID为01011时对应的CCCH,LCID为01100时对应的CCCH中的一个。
结合表1,下面给出一种该方法1.3的具体示例,如表8所示。
表8第二域的取值和LCID域的取值指示的内容
第二域 LCID域 指示的内容
0 01110 第一信息+quality value1
0 01111 第二信息+quality value1
0 10001 第三信息+quality value1
1 01110 第一信息+quality value2
1 01111 第二信息+quality value2
1 10001 第三信息+quality value2
该表8中的第一信息、第二信息、第三信息共有6种不同的预定义方式,分别如下:
1)、第一信息:CCCH;第二信息:CCCH和终端支持单播跳频;第三信息:CCCH和终端为0类(Category 0)终端;
2)、第一信息:CCCH;第二信息:CCCH和终端为0类(Category 0)终端;CCCH;第三信息:CCCH和终端支持单播跳频;
3)、第一信息:CCCH和终端支持单播跳频;第二信息:CCCH;第三信息:CCCH和终端为0类(Category 0)终端;
4)、第一信息:CCCH和终端支持单播跳频;第二信息:CCCH和终端为0类(Category 0)终端;第三信息:CCCH;
5)、第一信息:CCCH和终端为0类(Category 0)终端;第二信息:CCCH;第三信息:CCCH和终端支持单播跳频;
6)、第一信息:CCCH和终端为0类(Category 0)终端;第二信息:CCCH和终端支持单播跳频;第三信息:CCCH。
实际应用中,可以选择上述任一种作为预定义的第一信息、第二信息和第三信息。
进一步的,针对表8中的quality value1和quality value2,其可以采用类似于上述表5-1、或表5-2、或表6任一所示的预定义方式,可参考前述方式实现,不再赘述。
因此,该方法1.3中,通过第二域和LCID域,可以指示3个信息(第一信息、第二信息或第三信息)和2个quality value,每个quality value对应一个取值范围或至少一个取值。
以上是对方法1.3中的作为示例的表8的解释说明。结合该表8,终端使用该表8向接入网设备发送用于指示下行信道质量和CCCH的方式与上述方法1.2中的相关描述类似,可参考前述描述。需要说明的是,该方法1.3可以用于指示3种不同类型的信息和2种quality value。
方法2,MAC PDU子头中的第二域的取值和第三域的取值用于指示下行信道质量;第二域为第一域且第三域为F域,或者,第二域为第一域且第三域为F2域,或者,第二域为F域且第三域为F2域。
下面给出两种不同的示例进行说明。
方法2.1,当第二域的取值为0,且第三域的取值为0时,无下行信道质量。
结合表1,下面给出一种该方法2.1的具体示例,如表9所示。
表9第二域的取值和第三域的取值用于指示下行信道质量
第二域 第三域 指示的下行信道质量
0 0 No quality value
0 1 quality value2
1 0 quality value3
1 1 quality value4
该方法2.1中,第二域和第三域有以下几种实现方式:
(1)、第二域为第一域,第三域为F域;
(2)、第二域为第一域,第三域为F2域;
(3)、第二域为F域,第三域为F2域。
由于目前Msg3中携带的数据量较少,一般不会超过1000比特,因此Msg3可以采用如图2a所示的MAC PDU子头结构,因而F域和F2域的取值始终均为0,因此也可以利用F域和F2域的其它取值组合来指示下行信道质量。
上述表9所示的方案中,对于第二域和第三域的取值同时为0的场景,不做定义,即不使用,只对其他取值组合进行定义。
其中,上述表9可以用于指示3个quality value,分别为quality value2,quality value3和quality value4。
针对表9中的quality value2、quality value3和quality value4的具体实现方式,其可以采用类似于上述表5-1、或表5-2、或表6任一所示的预定义方式,可参考前述方式实现,不再赘述。需要说明的是,上述表9中并不存在quality value1。
以上是对方法2.1中的作为示例的表9的解释说明。结合该表9,终端使用该表9向接入网设备发送用于指示下行信道质量的方式与上述方法1中的相关描述类似,可参考前述描述。
方法2.2,当第二域的取值为0,且第三域的取值为0时,对应一个下行信道质量。
结合表1,下面给出一种该方法2.2的具体示例,如表10所示。
表10第二域的取值和第三域的取值用于指示下行信道质量
第二域 第三域 指示的下行信道质量
0 0 quality value1
0 1 quality value2
1 0 quality value3
1 1 quality value4
该方法2.2与上述方法2.1的主要区别在于:第二域的取值和第三域的取值同时为0时,也用于指示一个下行信道质量,即quality value1。
其中,上述表10可以用于指示4个quality value,分别为quality value1,quality value2,quality value3和quality value4。
针对表10中的quality value1、quality value2、quality value3和quality value4的具体实现方式,其可以采用类似于上述表5-1、或表5-2、或表6任一所示的预定义方式,可参考前述方式实现,不再赘述。
以上是对方法2.2中的作为示例的表10的解释说明。结合该表10,终端使用该表10向接入网设备发送用于指示下行信道质量的方式与上述方法1中的相关描述类似,可参考前述描述。
方法3,MAC PDU子头中的第二域的取值、第三域的取值和第四域的取值用于指示下行信道质量,第二域为第一域、第三域为F域,第四域为F2域。
下面给出两种不同的示例进行说明。
方法3.1,当第二域的取值为0,第三域的取值为0,且第四域的取值为0时,无下行信道质量。
结合表1,下面给出一种该方法3.1的具体示例,如表11所示。
表11第二域的取值、第三域的取值和第四域的取值用于指示下行信道质量
第二域的取值 第三域的取值 第四域的取值 指示的下行信道质量
0 0 0 No quality value
0 0 1 quality value2
0 1 0 quality value3
0 1 1 quality value4
1 0 0 quality value5
1 0 1 quality value6
1 1 0 quality value7
1 1 1 quality value8
由于目前Msg3中携带的数据量较少,一般不会超过1000比特,因此Msg3可以采用如图2a所示的MAC PDU子头结构,因而F域和F2域的取值始终均为0,因此也可以利用F域和F2域的其它取值组合来指示下行信道质量。
上述表11所示的方案中,对于第二域、第三域和第四域的取值同时为0的场景,不做定义,即不使用。只对其他取值组合进行定义。
其中,上述表11可以用于指示7个quality value,分别为quality value2至quality  value8。
针对表11中的quality value2至quality value8的具体实现方式,其可以采用类似于上述表5-1、或表5-2、或表6任一所示的预定义方式,可参考前述方式实现,不再赘述。需要说明的是,上述表11中并不存在quality value1。
以上是对方法3.1中的作为示例的表11的解释说明。结合该表11,终端使用该表11向接入网设备发送用于指示下行信道质量的方式与上述方法3.1中的相关描述类似,可参考前述描述。
方法3.2,当第二域的取值为0,第三域的取值为0且第四域的取值为0时,对应一个下行信道质量。
结合表1,下面给出一种该方法3.2的具体示例,如表12所示。
表12第二域的取值、第三域的取值和第四域的取值用于指示下行信道质量
第二域的取值 第三域的取值 第四域的取值 指示的下行信道质量
0 0 0 quality value1
0 0 1 quality value2
0 1 0 quality value3
0 1 1 quality value4
1 0 0 quality value5
1 0 1 quality value6
1 1 0 quality value7
1 1 1 quality value8
该方法3.2与上述方法3.1的主要区别在于:第二域的取值、第三域的取值和第四域的取值同时为0时,也用于指示一个下行信道质量,即quality value1。
其中,上述表12可以用于指示8个quality value,分别为quality value1至quality value8。
针对表12中的quality value1至quality value8的具体实现方式,其可以采用类似于上述表5-1、或表5-2、或表6任一所示的预定义方式,可参考前述方式实现,不再赘述。
以上是对方法3.2中的作为示例的表12的解释说明。结合该表12,终端使用该表12向接入网设备发送用于指示下行信道质量的方式与上述方法1中的相关描述类似,可参考前述描述。
方法4,LCID域的取值用于指示下行信道质量。
由于Msg3传输的特殊性,很多LCID的取值在Msg3中并不会使用,因此可以使用这些不会在Msg3使用的LCID取值来指示信道质量。例如,参考上述表1,Msg3的LCID的以下取值并不会被使用,因此可以用来指示下行信道质量和CCCH:10010、10011、10100、10101、10110、10111、11000、11011。此处,还可以结合保留的LCID的取值。
该方法4与上述方法1类似,只是该方法4没有使用到第二域。该方法4也包括3种实现方案,分别可用于指示1个CCCH、2个CCCH和3个CCCH。
方法4.1,LCID域的取值用于指示第一信息和下行信道质量;其中,第一信息为 CCCH,CCCH和终端支持单播跳频,CCCH和终端为0类(Category 0)终端中的任意一个,或者,第一信息是LCID为00000时对应的CCCH,LCID为01011时对应的CCCH,LCID为01100时对应的CCCH中的任意一个。
结合表1,下面给出一种该方法4.1的具体示例,如表13所示,此处仅以8个LCID取值为例,本发明不限制LCID的取值的个数,任意个数的LCID的取值的个数都在本发明的保护范围内。
表13 LCID域的取值指示的内容
LCID域 指示的内容
10010 第一信息+quality value1
10011 第一信息+quality value2
10100 第一信息+quality value3
10101 第一信息+quality value4
10110 第一信息+quality value5
10111 第一信息+quality value6
11000 第一信息+quality value7
11011 第一信息+quality value8
根据表13,由于Msg3的LCID域的取值为10010、10011、10100、10101、10110、10111、11000、11011时,没有被使用,因此该方法基于该特征,使用LCID域的这8个取值,来指示CCCH和下行信道质量。
需要说明的是,此时表1中原来的LCID为00000时指示的CCCH、LCID为01011指示的CCCH、LCID为01100指示的CCCH的含义仍然可以适用。或者理解为,基于本申请既可以使用LCID分别为00000、01011和01100来指示CCCH,也可以使用LCID为10010、10011、10100、10101、10110、10111、11000、11011时来指示第一信息和下行信道质量。
对于上述表13中的第一信息和quality value的解释,可以参考前述表4中对于第一信息和quality value的解释,不再赘述。需要说明的是,可以将上述表13中的LCID的8种取值互换位置。一旦选择一种定义方式,则将以该方式作为预定义的对应关系,在具体使用中将只能参照这一种对应关系。
以上是对方法4.1中的作为示例的表13的解释说明。下面以表13为例,介绍说明终端如何使用该表13,向接入网设备上报下行信道质量,即终端如何使用上述表13来执行上述步骤302。
假设终端测量得到的下行信道质量的取值为下行控制信道的重复次数,上述表13定义的quality value对应下行控制信道的重复次数的取值范围。
比如,终端测量得到的下行信道质量的取值为M(即下行控制信道的重复次数等于M),则终端查找上述表13,确定下行控制信道的重复次数取值为M时对应的LCID域的取值,假设下行控制信道的重复次数取值为M属于quality valueN对应的取值范 围,则终端确定quality valueN对应的LCID域的取值。比如,M=5,且下行控制信道的重复次数取值为5属于quality value4对应的取值范围,则根据上述表13,确定LCID域为10101,即终端将会在MAC PDU头的MAC PDU子头的LCID域填充10101。
相对应的,接入网设备接收到终端发送的Msg3之后,获取MAC PDU头的MAC PDU子头中各个域的信息,接入网设备获取到LCID域的取值(比如LCID域的取值为10101),则接入网设备可以通过查找上述表13,确定终端上报的下行信道质量的取值、CCCH和终端的类型(比如确定下行信道质量的取值是在quality value4对应的取值范围内,以及确定第一信息。即基于该示例,接入网设备并不能准确获知终端测量到的下行信道质量的取值,而只能获知终端测量到的下行信道质量对应的取值范围。
当然,若希望接入网设备可以准确获知终端测量到的下行信道质量的取值,则可以将上述表13中的各个quality value分别对应一个取值,这种方式可以使得接入网设备通过Msg3准确获知终端测量得到的下行信道质量的取值。但基于该方法4.1,只能预定义8种具体的下行信道质量的取值,比较受限,因此一般情形下,若接入网设备不要求获知准确的下行信道质量的取值,则可以将上述quality value均对应一个取值范围。
以下方法4.2和方法4.3,与上述方法4.1类似,只是方法4.2可以指示2个信息(第一信息或第二信息)和4个quality value,方法4.3可以指示3个信息(第一信息、第二信息或第三信息)和3个quality value。下面分别说明。
方法4.2,LCID域的取值用于指示第一信息和下行信道质量,或用于指示第二信息和下行信道质量;其中,第一信息、第二信息为CCCH,CCCH和终端支持单播跳频,CCCH和终端为0类(Category 0)终端中的任意两个,或者,第一信息、第二信息是LCID为00000时对应的CCCH,LCID为01011时对应的CCCH,LCID为01100时对应的CCCH中的任意两个。
结合表1,下面给出一种该方法4.2的具体示例,如表14所示。
表14 LCID域的取值指示的内容
LCID域 指示的内容
10010 第一信息+quality value1
10011 第二信息+quality value1
10100 第一信息+quality value2
10101 第二信息+quality value2
10110 第一信息+quality value3
10111 第二信息+quality value3
11000 第一信息+quality value4
11011 第二信息+quality value4
该表7中的第一信息、第二信息共有6种不同的预定义方式,分别如下:
1)、第一信息:CCCH;第二信息:CCCH和终端支持单播跳频;
2)、第一信息:CCCH;第二信息:CCCH和终端为0类(Category 0)终端;
3)、第一信息:CCCH和终端支持单播跳频;第二信息:CCCH;
4)、第一信息:CCCH和终端支持单播跳频;第二信息:CCCH和终端为0类(Category 0)终端;
5)、第一信息:CCCH和终端为0类(Category 0)终端;第二信息:CCCH;
6)、第一信息:CCCH和终端为0类(Category 0)终端;第二信息:CCCH和终端支持单播跳频。
实际应用中,可以选择上述任一种作为预定义的第一信息和第二信息。
或者理解为,
该表7中的第一信息、第二信息共有6种不同的预定义方式,分别如下:
1)、第一信息:LCID为00000时对应的CCCH;第二信息:LCID为01011时对应的CCCH;
2)、第一信息:LCID为00000时对应的CCCH;第二信息:LCID为01100时对应的CCCH;
3)、第一信息:LCID为01011时对应的CCCH;第二信息:LCID为00000时对应的CCCH;
4)、第一信息:LCID为01011时对应的CCCH;第二信息:LCID为01100时对应的CCCH;
5)、第一信息:LCID为01100时对应的CCCH;第二信息:LCID为00000时对应的CCCH;
6)、第一信息:LCID为01100时对应的CCCH;第二信息:LCID为01011时对应的CCCH。
实际应用中,可以选择上述任一种作为预定义的第一信息和第二信息。
进一步的,针对表14中的quality value1至quality value4,其可以采用类似于上述表5-1、或表5-2、或表6任一所示的预定义方式,可参考前述方式实现,不再赘述。
因此,该方法4.2中,通过LCID域,可以指示2个信息和4个quality value,每个quality value对应一个取值范围或至少一个取值。
以上是对方法4.2中的作为示例的表14的解释说明。下面以表14为例,介绍说明终端如何使用该表14,向接入网设备上报下行信道质量,即终端如何使用上述表14来执行上述步骤302。
假设终端测量得到的下行信道质量的取值为下行控制信道的重复次数,上述表14定义的quality value对应下行控制信道的重复次数的取值范围。
比如,终端测量得到的下行信道质量的取值为M(即下行控制信道的重复次数等于M),且确定的信息为第一信息,则终端查找上述表14,确定下行控制信道的重复次数取值为M时对应的LCID域的取值,假设下行控制信道的重复次数取值为M属于quality valueN对应的取值范围,则终端确定quality valueN对应的第二域的取值和LCID域的取值。比如,M=5,且下行控制信道的重复次数取值为5属于quality value2对应的取值范围,则根据上述表14,确定LCID域为10100,即终端将会在MAC PDU头的MAC PDU子头的在LCID域填充10100。
相对应的,接入网设备接收到终端发送的Msg3之后,获取MAC PDU头的MAC PDU子头中各个域的信息,接入网设备获取到LCID域的取值(比如LCID域的取值为10100,接入网设备可以通过查找上述表14,确定终端上报的下行信道质量的取值、CCCH和终端的类型(比如确定下行信道质量的取值是在quality value2对应的取值范围内,且确定为第一信息。即基于该示例,接入网设备并不能准确获知终端测量到的下行信道质量的取值,而只能获知终端测量到的下行信道质量对应的取值范围。进一步的,相较于方法4.1,该方法4.2中终端对应的信息可以有两种。
当然,若希望接入网设备可以准确获知终端测量到的下行信道质量的取值,则可以将上述表14中的各个quality value分别对应一个取值,这种方式可以使得接入网设备通过Msg3准确获知终端测量得到的下行信道质量的取值。但基于该方法4.2,只能预定义4种具体的下行信道质量的取值,比较受限,因此一般情形下,若接入网设备不要求获知准确的下行信道质量的取值,则可以将上述quality value均对应一个取值范围。
方法4.3,LCID域的取值用于指示第一信息和下行信道质量,或用于指示第二信息和下行信道质量,或用于指示第三信息和下行信道质量;其中,第一信息、第二信息、第三信息分别为CCCH,CCCH和终端支持单播跳频,CCCH和终端为0类(Category 0)终端中的一个,或者,第一信息、第二信息、第三信息分别是LCID为00000时对应的CCCH,LCID为01011时对应的CCCH,LCID为01100时对应的CCCH中的一个。
结合表1,下面给出一种该方法4.3的具体示例,如表15所示。
表15 LCID域的取值指示的内容
LCID域 指示的内容
10010 第一信息+quality value1
10011 第二信息+quality value1
10100 第三信息+quality value1
10101 第一信息+quality value2
10110 第二信息+quality value2
10111 第三信息+quality value2
11000 第一信息+quality value3
11011 第二信息+quality value3
该表15中的第一信息、第二信息、第三信息共有6种不同的预定义方式,分别如下:
1)、第一信息:CCCH;第二信息:CCCH和终端支持单播跳频;第三信息:CCCH 和终端为0类(Category 0)终端;
2)、第一信息:CCCH;第二信息:CCCH和终端为0类(Category 0)终端;CCCH;第三信息:CCCH和终端支持单播跳频;
3)、第一信息:CCCH和终端支持单播跳频;第二信息:CCCH;第三信息:CCCH和终端为0类(Category 0)终端;
4)、第一信息:CCCH和终端支持单播跳频;第二信息:CCCH和终端为0类(Category 0)终端;第三信息:CCCH;
5)、第一信息:CCCH和终端为0类(Category 0)终端;第二信息:CCCH;第三信息:CCCH和终端支持单播跳频;
6)、第一信息:CCCH和终端为0类(Category 0)终端;第二信息:CCCH和终端支持单播跳频;第三信息:CCCH。
实际应用中,可以选择上述任一种作为预定义的第一信息、第二信息和第三信息。
进一步的,针对表15中的quality value1至quality value3,其可以采用类似于上述表5-1、或表5-2、或表6任一所示的预定义方式,可参考前述方式实现,不再赘述。
因此,该方法4.3中,通过LCID域,可以指示3个信息(第一信息、第二信息或第三信息)和3个quality value,每个quality value对应一个取值范围或至少一个取值。
以上是对方法4.3中的作为示例的表15的解释说明。结合该表15,终端使用该表15向接入网设备发送用于指示下行信道质量的方式与上述方法4.2中的相关描述类似,可参考前述描述。需要说明的是,该方法4.3可以用于指示3种不同的信息和3种quality value。
需要说明的是,针对上述方法4中的任一方法,还可以使用第一域显式通知接入网设备:LCID域指示了下行信道质量,比如当第一域的取值为1时,接入网设备确定第一域的取值为1,则确定LCID域指示了下行信道质量,然后通过上述方法4.1或4.2或4.3确定信息和下行信道质量。再比如当F域的取值为1时,接入网设备确定F域的取值为1,则确定LCID域指示了下行信道质量,然后通过上述方法4.1或4.2或4.3确定信息和下行信道质量。再比如当F2域的取值为1时,接入网设备确定F2域的取值为1,则确定LCID域指示了下行信道质量,然后通过上述方法4.1或4.2或4.3确定信息和下行信道质量。
本申请还提供一种通过MAC PDU子头指示下行信道质量的方法,该方法与上述方法1至方法4均不同,该方法是对MAC PDU子头进行扩展,增加一行或一个字节,或增加一个或多个域(称为扩展域),然后利用增加的一个字节或扩展域携带或指示下行信道质量。
方法5,MAC PDU子头中的第N行的域用于指示下行信道质量,N可以等于2或3或4或5。
该MAC PDU子头的第N行的域可以包括Y个扩展域,分别包括(Y-1)个R域(1比特)和1个质量报告(quality report,QR)域(8-Y+1比特),其中Y为{1,2,3,4,5,6,7,8}中的一个元素。
如图2e所示,为本申请自定义的一种MAC PDU子头的格式。图中是以N=3为例。该MAC PDU子头的第三行的域包括5个扩展域,分别为R,R,R,R和QR域,即增加了一个字节,其中,QR域用于携带或指示下行信道质量,QR域为4比特,4 个扩展的R域分别为1比特。
下面以该MAC PDU子头包括5个扩展域为例进行说明。
比如,当MAC PDU子头中的第一域的取值为1,则第3行的域的部分比特位(即QR域)携带或指示下行信道质量。或者,当MAC PDU子头中的F域的取值为1时,则第3行的域的部分比特位(即QR域)携带或指示下行信道质量。或者,当MAC PDU子头中的F2域的取值为1时,第3行的域的部分比特位(即QR域)携带或指示下行信道质量。
比如,若通过QR域携带下行信道质量,则可以携带16种不同的下行信道质量的取值。该方案是直接在QR域携带下行信道质量的取值。
再比如,若通过QR域指示下行信道质量,则可以指示16种不同的quality value,一个quality value对应至少一个取值或者对应一个取值范围。
通过以上任一方案,可以实现通过Msg3指示下行信道质量,从而接入网设备可以获知下行信道质量。
下面给出另一种解决方案,该解决方案是结合终端所处的覆盖增强等级和索引来指示下行信道质量。
如图4所示,为本申请提供的又一种下行信道质量的上报方法,该方法包括以下步骤:
步骤401,终端确定终端所处的覆盖增强等级(coverage enhancement level,CE level)和下行信道质量。
步骤402,终端在CE level下,确定与所述下行信道质量对应的索引。
这里的索引也可以称为上报值。
步骤403,终端向接入网设备发送所述索引。
步骤404,接入网设备根据CE level和索引,确定下行信道质量。
需要说明的是,接入网设备可以根据以下任一方法确定上述CE level:
方法1,终端向接入网设备发送随机接入前导码,所述随机接入前导码用于指示终端所处的CE level或指示所述随机接入前导码与终端所处的CE level对应;接入网设备接收终端发送的随机接入前导码,根据随机接入前导码确定终端所处的CE level。
方法2,终端使用第一资源向接入网设备发送上述索引,所述第一资源用于指示终端所处的CE level或指示所述第一资源与终端所处的CE level对应;接入网设备接收终端发送的索引时,可以根据发送索引的第一资源确定终端所处的CE level。
方法3,终端向接入网设备发送参考信号接收功率(Reference Signal Receiving Power,RSRP),接入网设备根据接收到的RSRP确定终端的CE level。
基于该方案,终端确定所述终端所处的CE level和下行信道质量,然后终端在CE level下,确定与所述下行信道质量对应的索引,并向接入网设备发送所述索引,从而接入网设备可以根据该索引,确定该下行信道质量,从而实现了向接入网设备上报下行信道质量。其中,该索引可以是携带于Msg3发送至接入网设备的。
下面对上述方案进行说明。对于终端,可以认为其移动较慢或在随机接入过程中信道环境变化较小,因此,终端在确定上述需要在Msg3上报的下行信道质量(如下行控制信道的重复次数)时,其下行信道质量与CE level有一定的对应关系。
在一种可能的实施方式中,CE level可以分为CE level 0、CE level1、……、CE level K这(K+1)个等级,其中,K为正整数。例如,当前CE level可以分为CE level 0、CE level 1、CE level 2、CE level 3四个等级。当终端处于CE level 0时,终端信道条件最好,此时需要较少的下行控制信道的重复次数或不用重复,因此,当终端处于CE level 0时,其确定的下行控制信道的重复次数不会非常大,即其一定在一个较小的范围内。相应地,当终端处于CE level 1、CE level 2、CE level 3时,则下行控制信道的重复次数依次增大。因而,CE level与下行信道质量之间是具有对应关系的。
以终端所处的CE level包括四个等级,即CE level 0、CE level 1、CE level 2、CE level 3为例,则可以预先定义每个CE level与下行信道质量之间的对应关系,这里的下行信道质量可以为下行控制信道的重复次数(repetition number)、或为下行控制信道的重复次数的范围,或为下行控制信道的聚合等级(aggregation level)、或为下行控制信道的聚合等级的范围。
在一种可能的实施方式中,所述覆盖增强等级所对应的所述索引或上报值,和/或所述下行信道质量所对应的所述索引或上报值,由网络配置或协议预定义。
在一种可能的实施方式中,第i个CE level可以对应Qi个下行信道质量取值,其中Qi为正整数,i为正整数。
例如,以下行控制信道的重复次数为例,则可以预先定义CE level与下行信道质量之间的对应关系。如表16为CE level与下行信道质量的取值之间的对应关系的一个示例。其中,每个CE level对应2个下行信道质量取值。
表16 CE level与下行信道质量的取值之间的对应关系
Figure PCTCN2018125813-appb-000010
在一种可能的实施方式中,每个下行信道质量取值可以是一个数值或多个数值或一个数值范围。如表16所示,quality value1对应的取值包括a1,a2,……aA,其中A为正整数;quality value2对应的取值包括b1,b2,……bB,其中B为正整数;quality value3对应的取值包括c1,c2,……,cC,其中C为正整数;quality value4对应的取值包 括d1,d2,……,dD,其中D为正整数;quality value5对应的取值包括e1,e2,……,eE,其中E为正整数;quality value6对应的取值包括f1,f2,……,fF,其中F为正整数;quality value7对应的取值包括g1,g2,……,gG,其中G为正整数;quality value8对应的取值包括h1,h2,……,hH,其中H为正整数。可选地,上述取值可以满足:
a1<a2<a3<…<aA;
b1<b2<b3<…<bB;
……
h1<h2<h3<…<hH;
并且,同一个CE level对应的不同quality value之间没有重叠的取值,不同CE level对应的quality value之间可以有部分重叠的取值。比如,quality value1与quality value2之间没有重叠的取值,quality value3与quality value4之间没有重叠的取值,quality value5与quality value6之间没有重叠的取值,quality value7与quality value8之间没有重叠的取值。再比如,quality value1可以与quality value3或quality value4之间有部分重叠的取值,再比如,quality value2可以与quality value3或quality value4之间有部分重叠的取值,等等。
如表16a为CE level与下行信道质量的取值之间的对应关系的又一个示例。其中,每个CE level对应4个下行信道质量取值。

具体说明如上,此处不再赘述。再比如,以下行控制信道的重复次数的范围为例,则可以预先定义CE level与下行信道质量的取值范围之间的对应关系。如表17为CE level与下行信道质量的取值范围之间的对应关系的一个示例。其中,每个CE level对应2个下行信道质量取值范围。

X1<X3<X5<X7<X9<X11<X13<X15,X2<X4<X6<X8<X10<X12<X14<X16。
如表17a为CE level与下行信道质量的取值范围之间的对应关系的又一个示例。其中,每个CE level对应4个下行信道质量取值范围。

具体说明如上,此处不再赘述。在一种可能的实施方式中,每一个CE level与下行信道质量的取值或取值范围对应关系都对应或预定义一个索引。例如,基于上述表16或表16a或表17或表17a所示的CE level与下行信道质量之间的对应关系,可以为每一个对应关系预定义一个索引。以表16为例,由于每个CE level对应两个quality value,因此可以使用两个索引(在具体实现中,可以使用1比特)来表示。如表18所示,为CE level、索引及下行信道质量之间的对应关系。

因此,上述表18即为CE level、索引及下行信道质量之间的对应关系,可以通过网络配置或协议预定义的方式,配置在终端和接入网设备上。
同样地,基于表16a,由于每个CE level对应4个quality value,因此可以使用4个索引(在具体实现中,可以使用2比特)来表示。如表18a所示,为CE level、索引及下行信道质量之间的对应关系。

在一种可能的实施方式中,上述表18a、表18c、表19a-1、表19a-2、表19a-3、表19a-4、表19c-1、表19c-2、表19c-3、表19c-4中的索引“0”、“1”、“2”和“3”可由“00”、“01”、“10”和“11”代替。
下面以表18为例。当终端和接入网设备均存储该表18时,则终端可以基于表18上报下行信道质量,而接入网设备可以基于表18获取下行信道质量。
假设终端测量得到的下行信道质量的取值为下行控制信道的重复次数,上述表18定义的quality value对应下行控制信道的重复次数的取值。
比如,终端测量得到的下行信道质量的取值为M(即下行控制信道的重复次数等于M),且终端确定终端所处的CE level为CE level N,则终端在CE level N下确定与该下行信道质量对应的索引为L,比如,下行控制信道的重复次数取值为5属于quality value2的取值,即quality value2包括5,则终端确定的索引的值为1。
因此可以将索引L(例如,L=1)发送至接入网设备,例如可以通过MAC PDU子头的第一域、F域或F2域发送,即将第一域、F域或F2域置为1。或者还可以使用RRC消息的1比特发送所述索引L(例如,L=1)。
相对应的,接入网设备接收到终端发送的索引后(比如接收到Msg3或RRC消息),获取索引的值,则接入网设备可以通过查找上述表18,根据索引L(例如,L值为1)和终端所处的CE level N确定下行信道质量在quality value P(例如quality value2)对应的取值范围内。即基于该示例,接入网设备并不能准确获知终端测量到的下行信道质量的取值,而只能获知终端测量到的下行信道质量对应的取值范围。
当然,若希望接入网设备可以准确获知终端测量到的下行信道质量的取值,则可以将上述表18中的各个quality value分别对应一个取值,这种方式可以使得接入网设备通过准确获知终端测量得到的下行信道质量的取值。但基于该方法,只能预定义8种具体的下行信道质量的取值,比较受限,因此一般情形下,若接入网设备不要求获知准确的下行信道质量的取值,则可以将上述quality value均对应一个取值范围。
在一种可能的实施方式中,上述只是以一个CE level对应两个quality value为例,实际应用中,一个CE leve还可以对应4个quality value、8个quality value、16 quality value等等,即一个CE level可以对应2 N个quality value,N为正整数,相应地,则需要N个比特用来发送索引。
在一种可能的实施方式中,上述只是以终端所处的CE level包括4个CE level为例,实际应用中,可以包括M个CE level,其中M为大于1的整数。
作为又一种可能的实现方法,本申请还提供一种信道质量上报方法,包括:
步骤A,终端确定载波(carrier)或窄带(narrowband)发生改变。
步骤B,终端上报下行信道质量。
基于该方案,当终端确定载波或窄带发生改变时,触发终端上报下行信道质量。即载波或窄带的改变是终端上报下行信道质量的触发条件。
在前述方法中,给出了一种触发终端上报下行信道质量的方法,即接入网设备向终端发送指示信息,该指示信息用于指示允许终端上报下行信道质量。而这里的方案给出另一种触发终端上报下行信道质量的方法。
对于NB-IoT,终端工作于一个载波上,接入网设备可以配置终端更换到另一个载波。对于MTC,终端工作于一个窄带上,接入网设备可以配置终端更换到另一个窄带 上。由于终端在不同载波或不同窄带上的信道环境不同,所以需要终端上报下行信道质量。
基于该信道质量上报方法,对于上述步骤B中的终端上报下行信道质量的具体实现方法,可以参考前述任一实施例中的终端上报下行信道质量,这里不再赘述。
可以理解的是,上述方法实施例中,由终端实现的方法,也可以由可用于终端的部件(例如芯片或者电路)实现,本申请实施例对此不作限定。
