具体实施方式
下面将结合附图,对本申请实施例中的技术方案进行描述。
应理解,本申请实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile Communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、以及未来的5G通信系统等。
本申请结合终端设备描述了各个实施例。终端设备也可以指用户设备 (User Equipment,UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(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,未来5G网络中的终端设备或者未来演进的陆上公用移动通信网(Public Land Mobile Network,PLMN)网络中的终端设备等。
本申请结合网络设备描述了各个实施例。网络设备可以是用于与终端设备进行通信的设备,例如,可以是GSM系统或CDMA中的基站(Base Transceiver Station,BTS),也可以是WCDMA系统中的基站(NodeB,NB),还可以是LTE系统中的演进型基站(Evolutional Node B,eNB或eNodeB),或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络侧设备或未来演进的PLMN网络中的网络侧设备等。
图1是本申请实施例的一个应用场景的示意图。图1中的通信系统可以包括网络设备10和终端设备20。网络设备10用于为终端设备20提供通信服务并接入核心网,终端设备20可以通过搜索网络设备10发送的同步信号、广播信号等而接入网络,从而进行与网络的通信。图1中所示出的箭头可以表示通过终端设备20与网络设备10之间的蜂窝链路进行的上/下行传输。
本申请实施例中的网络可以是指公共陆地移动网络(Public Land Mobile Network,PLMN)或者设备对设备(Device to Device,D2D)网络或者机器对机器/人(Machine to Machine/Man,M2M)网络或者其他网络,图1只是举例的简化示意图,网络中还可以包括其他终端设备,图1中未予以画出。
在未来的通信系统中,如果信道互异性(channel reciprocity)成立,则对于下行链路(Downlink,DL),终端设备不需要向网络设备反馈信道的预编码矩阵指示信息(Precoding Matrix Indicator,PMI),大大降低了信令开销,并且使得同时网络具有更大的自由度去选择一个更优的预编码矩阵。
但是,由于网络侧和终端侧的干扰不同,因此,所以终端设备仍然需要把干扰相关的信息通知给网络,以便网络能够选择较好的调制编码等级(Modulation and Coding Scheme,MCS)来进行传输,因此CQI的反馈仍然是必须的。
假设网络配置用于传输信道状态指示参考信号(Channel State Indication Reference Signals,CSI-RS)的CSI-RS资源,该CSI-RS信号资源包括N个端口。终端设备根据对该CSI-RS的测量,可以获知下行链路(Uplink,DL)对应的信道,同时可以通过干扰测量资源(Interference Measurement Resource,IMR)进行干扰测量,综合考虑信道信息和干扰信息以计算CQI,并将该CQI上报给网络。
在未来的通信系统例如在5G或称新无线(New Radio,NR)通信系统中,由于天线数量的增多,MU-MIMO技术的使用概率相比于LTE系统将会大大增加,因此急需针对这一场景进行优化。
本申请实施例中,网络设备通过向终端设备指示用于计算CQI的K个端口,以使终端设备基于N个端口中的这K个端口计算CQI,从而可以获得更精确的CQI,提升了通信性能。
图2是本申请实施例的计算CQI的方法的示意性流程图。图2所示的方法可以由终端设备执行,该终端设备例如可以为图1中所示的终端设备20。如图2所示,该计算CQI的方法包括:
在210中,终端设备在N个端口中确定用于计算CQI的K个端口。
在220中,终端设备基于该K个端口计算该CQI。
在230中,终端设备向网络设备上报该CQI和秩。
其中,该秩(Rank,RI)等于K,K和N为正整数。
因此,终端设备基于N个端口中的K个端口计算CQI,可以获得更精确的CQI,从而提升通信性能。
可选地,在210中,终端设备在N个端口中确定用于计算CQI的K个端口,包括:终端设备根据该秩,在N个端口中选择预配置的该K个端口。
可选地,该K个端口(port)的端口号为0至K-1,或者为N-K至N-1。
例如,预配置的K个端口可以如表一所示。该K个端口的端口号分别为0至K-1,终端设备待上报的秩的值不同时,所选择的K个端口的也不同。
表一
端口
RI=1 port 0
RI=2 port 0、port 1
…… ……
RI=K port 0、port 1、……、port K
…… ……
RI=N port 0、port 1、……、port K、……port N
又例如,预配置的K个端口可以如表二所示。该K个端口的端口号分别为N-K至N-1,终端设备待上报的秩的值不同时,所选择的K个端口的也不同。
表二
端口
RI=1 port N-1
RI=2 port N-2、port N-1
…… ……
RI=K port N-K、……、port N-2、port N-1
…… ……
RI=N port 0、……、port N-K、……、port N-2、port N-1
进一步地,可选地,若K为奇数,则该K个端口的端口号为0至K-1,若K为偶数,则该K个端口的端口号为N-K至N-1;或者,若K为偶数,则该K个端口的端口号为0至K-1,若K为奇数,则该K个端口的端口号为N-K至N-1。
可选地,该方法还包括:终端设备向网络设备发送所选择的该K个端口的信息。
也就是说,终端设备可以在N个端口中自己选择K个端口,并通过某个上行传输,将其选择的所述K个端口的信息发送给网络设备。
可选地,在210之前,即终端设备在N个端口中确定用于计算CQI的K个端口之前,该方法还包括:终端设备接收网络设备发送的第一配置信息,该第一配置信息用于指示该K个端口的信息;
其中,在210中,终端设备在N个端口中确定用于计算CQI的K个端口,包括:终端设备根据该第一配置信息,在该N个端口中确定该K个端口。
该实施例中,网络设备向终端设备发送第一配置信息以指示该K个端口 的信息,网络设备可以通过两种方式向该终端设备指示该K个端口的信息,下面分别描述。
方式1
可选地,该第一配置信息包括用于计算该CQI的目标端口配置,该目标端口配置包括多个秩与多个端口集合之间的对应关系,该多个秩中不同的秩对应的端口集合包括不同数量的端口,
其中,在210中,终端设备根据所述第一配置信息,在该N个端口中确定该K个端口,包括:终端设备根据该目标端口配置以及该秩,确定与该秩对应的第一端口集合,其中,该第一端口集合包括该K个端口。
具体地,网络设备可以通过第一配置信息直接向终端设备指示用于计算CQI的端口配置即目标端口配置,该目标端口配置中包括多个秩与多个端口集合之间的对应关系,例如该目标端口配置可以为表一或者表二所示的端口配置。终端设备根据该目标端口配置以及需上报的该秩,在该目标端口配置中确定与该秩对应的端口集合即第一端口集合,并基于该第一端口集合中的端口计算CQI。该目标端口配置中,多个秩与多个端口集合之间一一对应,不同秩对应的端口集合中的端口数量不同,例如秩为K时对应的该第一端口集合中包括K个端口。
方式2
可选地,该第一配置信息包括用于计算该CQI的目标端口配置的标识信息,该标识信息用于标识该目标端口配置;
其中,在210中,终端设备根据该第一配置信息,在该N个端口中确定该K个端口,包括:
终端设备根据该标识信息,在多个端口配置中,确定该标识信息指示的该目标端口配置,该多个端口配置中的每个端口配置包括多个秩与多个端口集合之间的对应关系,其中,在每个端口配置中,不同的秩对应的端口集合包括不同数量的端口;
终端设备根据该目标端口配置以及该秩,确定与该秩对应的第一端口集合,其中,该第一端口集合包括该K个端口。
具体地,终端设备中可以预存多个端口配置,网络设备可以通过第一配置信息向终端设备指示用于计算CQI的目标端口配置的标识信息,该标识信息用于标识该目标端口配置,从而终端设备能够根据该标识信息,在该多个 端口配置中找到该标识信息所指示的该目标端口配置。该多个端口配置中的每个端口配置都包括多个秩与多个端口集合之间的对应关系,每个端口配置中的多个秩与多个端口集合之间一一对应,且不同端口配置中与相同秩对应的端口集合可以不相同。终端设备基于该目标端口配置中与秩K对应的第一端口集合中的K个端口,计算该CQI。
应理解,当与秩K对应的端口集合有多个时,终端设备可以在于秩K对应的端口集合中选择一个作为用于计算CQI的该第一端口集合。
可选地,该第一端口集合中的该K个端口的端口号为0至K-1。
可选地,该第一端口集合中的该K个端口的端口号为N-K至N-1。
可选地,该第一端口集合中的该K个端口的端口号连续。
可选地,该第一端口集合中的该K个端口的端口号连续,且该K个端口的端口号中最小的端口号M满足M mod K=0,M为自然数。
举例来说,该多个端口配置可以包括表一、表二、表三和表四所示的这四种端口配置,该多个端口配置可以是网络设备通过第二配置信息告诉终端设备的,也可以是终端设备预存的例如协议中约定的。终端设备可以根据第一配置信息携带的标识信息,在该标识信息所指示的目标端口配置中,选择秩RI=K对应的第一端口集合,并基于第一端口集合中的K个端口计算CQI。
在表一中,与秩K对应的端口集合中的端口的端口号为port 0至port K-1。
在表二中,与秩K对应的端口集合中的端口的端口号为port N-K至port N-1。
在表三中,每个端口集合中的端口的端口号连续。
例如,RI=2时终端设备可以在与RI=2对应的多个端口集合(port 0,port 1)、(port 1,port 2)、……、(port N-2,port N-1)(可能还包括(port N-1,port 0))中选择一个作为用于计算CQI的该第一端口集合。
RI=3时终端设备可以在与RI=3对应的多个端口集合(port 0,port 1,port 2)、(port 1,port 2,port 3)、……、(port N-3,port N-2,port N-1)(可能还包括(port N-1,port 0,port 1)和(port N-2,port N-1,port 0))中选择一个作为用于计算CQI的该第一端口集合。
在表四中,每个端口集合中的端口的端口号连续,且该端口集合中的最小端口号为0或者为该端口集合对应的秩的值的整数倍。
例如,RI=2时终端设备可以在与RI=2对应的多个端口集合(port 0,port 1)、(port 2,port 3)、……、(port N-2,port N-1)(可能还包括(port N-1,port 0))中选择一个作为用于计算CQI的该第一端口集合。
RI=3时终端设备可以在与RI=3对应的多个端口集合(port 0,port 1,port 2)、(port 3,port 4,port 5)、……、(port N-3,port N-2,port N-1)(可能还包括(port N-1,port 0,port 1)或(port N-2,port N-1,port0))中选择一个作为用于计算CQI的该第一端口集合。
网络设备为终端设备配置了一个N端口的CSI-RS信号用来进行信道测量,终端设备在N个端口中进行端口选择并计算CQI,假设N=4,4个端口的端口号为port 1、port 2、port 3和port 4,那么表三和表四可以如下所示。
表三
Figure PCTCN2017105000-appb-000001
表四
端口
RI=1 port 0或port 1或port 2或port 3
RI=2 (port 0,port 1)或(port 2,port 3)
RI=3 (port 0,port 1,port 2)或(port 3,port 0,port 1)
RI=4 (port 0,port 1,port 2,port 3)
应理解,表一至表四仅仅为示例,在每种端口配置中,与秩对应的端口集合也可以为其他形式,当某个秩对应于多个端口集合时(例如表三和表四),终端设备可以在多种可能的端口集合中选择一个作为用于计算CQI的该第一端口集合,并且进一步地,终端设备可以在某个上行传输中将所选择的端口的信息上报给网络设备;当秩对应于一个端口集合时(例如表一和表二),终端设备基于该秩对应的端口集合中的端口计算CQI。
可选地,在终端设备接收网络设备发送的该第一配置信息之前,该方法还包括:终端设备接收网络设备发送的第二配置信息,该第二配置信息包括该多个端口配置。
可选地,终端设备接收网络设备发送的第二配置信息,包括:终端设备接收网络设备通过无线资源控制(Radio Resource Control,RRC)信令、介质访问控制(Medium Access Control,MAC)控制元素(Control Element,CE)发送的该第二配置信息。
可选地,终端设备接收网络设备发送的第一配置信息,包括:终端设备接收网络设备通过RRC信令、MAC CE或者下行控制信息(Download Control Information,DCI)发送的该第一配置信息。
例如,网络设备可以通过RRC信令向终端设备发送第二配置信息以指示该多个端口配置,并通过MAC CE向终端设备发送第一配置信息以指示用于计算CQI的目标端口配置的标识信息。
又例如,网络设备可以通过RRC信令向终端设备发送第二配置信息以指示该多个端口配置,并通过DCI向终端设备发送第一配置信息以指示用于计算CQI的目标端口配置的标识信息。
又例如,网络设备可以通过MAC CE向终端设备发送第二配置信息以指示该多个端口配置,并通过DCI向终端设备发送第一配置信息以指示用于计算CQI的目标端口配置的标识信息。

又例如,网络设备可以通过MAC CE直接向终端设备发送第一配置信 息以指示用于计算CQI的目标端口配置。
又例如,网络设备可以通过DCI直接向终端设备发送第一配置信息以指示用于计算CQI的目标端口配置。
上述的多个端口配置中,每个端口配置都是可以进行更新的。
可选地,该方法还包括:终端设备接收网络设备发送的更新配置信息,该更新配置信息中包括该目标端口配置中与该秩对应的第二端口集合;终端设备将该目标端口配置中与该秩对应所述第一端口集合,更新为该第二端口集合。
可选地,该终端设备接收网络设备发送的更新配置信息,包括:终端设备接收网络设备通过RRC信令、MAC CE或者DCI发送的该更新配置信息。
例如,网络设备可以通过RRC信令向终端设备发送该第一配置信息,并通过MAC CE或DCI向终端设备发送该更新配置信息。
又例如,网络设备可以通过MAC CE向终端设备发送该第一配置信息,并通过DCI向终端设备发送该更新配置信息。
又例如,网络设备可以通过DCI向终端设备发送该第一配置信息,并通过DCI向终端设备发送该更新配置信息。
可选地,在230中,终端设备在基于该K个端口计算该CQI时,将与所该K个端口属于CSI-RS资源的其他端口作为干扰;或者可以将与该K个端口属于相同CSI-RS资源的其他端口不作为干扰。
例如,网络设备为终端设备配置了一个4端口的CSI-RS信号用来进行信道测量,终端设备在4个端口中选择了2个端口用来计算CQI,那么终端设备在根据被选择的两个端口计算CQI时,与被选择的这两个端口属于同一个CSI-RS资源的另外两个端口可以被当做干扰,即干扰来自于该另外两个端口以及该CSI-RS资源外的其他端口;或者,与被选择的这两个端口属于同一个CSI-RS资源的另外两个端口也可以不被当做干扰,即干扰仅来自于该CSI-RS资源外的其他端口。
图3是本申请实施例的计算CQI的方法的示意性流程图。图3所示的方法可以由网络设备执行,该网络设备例如可以为图1中所示的网络设备10。如图3所示,该计算CQI的方法包括:
在310中,网络设备向终端设备发送第一配置信息,所述第一配置信息指示用于所述终端设备计算信道质量指示CQI的K个端口,以便于所述终 端设备根据所述第一配置信息在N个端口中确定所述K个端口,并基于所述K个端口计算所述CQI,并且上报所述CQI和秩,其中,所述秩等于K,K和N为正整数。
