Description
本申请涉及通信技术领域,特别是涉及一种通信方法、装置、终端和存储介质。
在新无线(New Radio,简称NR)***中,根据终端设备中各天线端口之间的相干特性,将终端设备的相干传输能力分为完全相干、部分相干以及非相干。终端设备向网络上报自身的相干传输能力。针对基于码本的上行传输,网络根据该终端设备的相干传输能力,在与该相干传输能力对应的码本子集中选择合适的预编码矩阵,并通过下行控制信息(Downlink Control Information,简称DCI)将该预编码矩阵对应的预编码矩阵指示符(Transmitted Precoding Matrix Indicator,简称TPMI)下发给终端设备,使得终端设备可以通过相应的预编码矩阵对上行数据进行预编码处理。其中,不同相干传输能力的终端设备对应不同码本子集,非相干类型的终端设备对应码本子集为nonCoherent,完全相干类型终端设备对应码本子集可以为fullyAndPartialAndNonCoherent,nonCoherent,或者partialAndNonCoherent,部分相干类型的终端设备对应的码本子集可以为nonCoherent,或者partialAndNonCoherent,nonCoherent是fullyAndPartialAndNonCoherent的子集。
在上行传输中,为了保证传输质量以及降低上行干扰,需要对终端设备的发射功率进行控制。在功率控制过程中,终端设备先根据网络配置信息等计算一个发射功率,然后在确定对计算出的发送功率进行缩放后,针对实际传输计算出功率缩放系数;并采用功率缩放系数对发射功率进行缩放后,分配至PUSCH的非零传输端口上进行传输。
但是,对于相干传输能力为部分相干以及非相干的终端设备,按照上述方法进行功率控制时,会出现终端设备无法达到最大发射功率的情况。

为了使本申请的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本申请进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本申请,并不用于限定本申请。
在新无线(New Radio,简称NR)***中,根据终端设备中各天线端口之间的相干特性,可以将终端设备的相干传输能力分为完全相干、部分相干以及非相干,其中:
非相干nonCoherent,是指终端设备中任意两个天线端口对应的相位差不能保持恒定关系,例如两个天线端口之间的相位差会发生变化,难以在一定时长内保持不变;或者在一定时长内两个天线端口之间的相位差变化幅度超出一定的范围。
部分相干partialCoherent,是指终端设备的天线端口分为多个组,每组天线端口之间的相位差可以保持恒定关系,但是不同组之间的天线端口之间的相位差不能保持恒定关系。
全相干fullCoherent,是指终端设备的所有天线端口之间的相位差可以保持恒定关系。上述天线端口是物理天线端口的抽象表示,天线端口与物理天线端口可以一一对应,也可以一对多。
终端设备向网络上报自身的相干传输能力;其中,2端口终端设备可以有非相干和全相干两种类型,4端口终端设备可以有非相干、部分相干和全相干三种类型。网络设备接收到终端设备上传的相干传输能力之后,针对基于码本的上行传输,可以根据该终端设备的相干传输能力,在与该相干传输能力对应的码本子集codebook subset中选择合适的预编码矩阵,可以通过DCI将该预编码矩阵对应的TPMI下发给终端设备,使得终端设备可以通过该TPMI对应的预编码矩阵对上行数据进行预编码处理。
目前协议规定了三种不同的码本子集,包括:fullyAndPartialAndNonCoherent,partialAndNonCoherent、nonCoherent。其中,fullyAndPartialAndNonCoherent,可以适用于相干传输能力为fullCoherent的终端;partialAndNonCoherent,可以适用于相干传输能力为partialCoherent以及fullCoherent的终端;nonCoherent:可用于相干传输能力为nonCoherent,partialCoherent以及fullCoherent的终端。其中,对于支持4个天线端口的终端设备,码本子集nonCoherent是partialAndNonCoherent的子集,partialAndNonCoherent是fullyAndPartialAndNonCoherent的子集。
在上行传输中,为了保证传输质量以及降低上行干扰,需要对终端设备的发射功率进行控制。上行功率控制过程中,终端设备可以根据网络配置信息,和/或上行传输对应的调度信息,例如频域资源分配信息、发射功率控制(transmit power control,简称TPC)命令等,计算一个发射功率;然后,终端设备根据当前传输情况,确定是否对所述计算得到的发射功率进行缩放;最后,当确定需要对所述计算得到发射功率进行缩放时,基于物理上行共享信道(Physical Uplink Shared Channel,简称PUSCH)端口信息计算出功率缩放系数,并采用功率缩放系数对计算得到的发射功率进行缩放后,分配至PUSCH非零传输端口上进行传输,其中PUSCH非零传输端口可以对应PUSCH所用的预编码矩阵的非零传输端口。
其中,缩放系数的计算方法为:PUSCH非零传输端口数目除以终端设备能支持的探测参考信号(Sounding Reference Signal,简称SRS)的最大端口数目。例如,对于相干传输能力为nonCoherent的2天线端口的终端设备,网络设备下发的TPMI对应的预编码矩阵为
由预编码矩阵可以看出对应的PUSCH非零传输端口数目为1,而终端设备能支持的最大端口数目为2,因此计算得到的 缩放系数为0.5。也就是说,当终端设备计算出的发射功率为20dBm时,实际发射功率只能是17dBm,因此会导致终端设备的最大发射功率为23dBm时,该终端设备实际发送的最大功率为20dBm。因此,对于相干传输能力为部分相干以及非相干的终端设备,按照上述方法进行功率控制时,无法使用最大功率发送上行信号,我们把这种情况简称为无法进行满功率发射。
基于上述情况,本申请实施例提供的一种通信方法。该方法可以应用于基于5G通信技术和IoT相关的技术的智能服务,例如智能家居,智能建筑,智能城市,智能汽车,联网汽车,医疗保健,数字教育,智能零售,安全和安全服务。图1为本申请实施例提供的通信方法的一种应用场景示意图。如图1所示,该场景包括网络设备100和终端设备200,网络设备100和终端设备200通过网络进行通信。其中,网络设备100可以是全球移动通讯(Global System of Mobile communication,简称GSM)或码分多址(Code Division Multiple Access,简称CDMA)中的基站(Base Transceiver Station,简称BTS),也可以是宽带码分多址(Wideband Code Division Multiple Access,简称WCDMA)中的基站(NodeB,简称NB),还可以是LTE中的演进型基站(Evolutional Node B,简称eNB或eNodeB),或者中继站或接入点,或者5G网络中的基站等,在此并不限定。
终端设备200可以是无线终端,无线终端可以是指向用户提供语音和/或其他业务数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(Radio Access Network,简称RAN)与一个或多个核心网进行通信,无线终端可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,例如,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,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,简称PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol,简称SIP)话机、无线本地环路(Wireless Local Loop,简称WLL)站、个人数字助理(Personal Digital Assistant,简称PDA)等设备。
下面以具体地实施例对本申请的技术方案以及本申请的技术方案进行介绍。下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图,对本申请的实施例进行描述。
图2为一个实施例中通信方法的流程图。本实施例中的通信方法,以运行于图1中的终端设备为例进行描述。如图2所示,上述通信方法包括以下步骤:
S101、向网络设备发送第一指示信息,所述第一指示信息指示第一预编码矩阵指示符TPMI组,第一TPMI组为TPMI组集合中的一个TPMI组。
可选的,第一TPMI组中的TPMI对应的预编码矩阵为支持终端设备进行PUSCH满功率发送的预编码矩阵。
其中,上述第一TPMI组为预设的TPMI组集合中的一个TPMI组。上述每个TPMI组对应的预编码矩阵集合中可以包括至少一个预编码矩阵。
在MIMO***中,终端设备和网络设备可以通过多个天线实现多个信号流在空中的并行传输。例如,在上行传输中,终端设备通过多个天线端口传输几路并行的数据流,然后网络设备在接收端再通过多个接收天线将并行的数据流接收下来,检测出终端设备发送的信号。
为了提高数据流的传输效率,MIMO***可以采用空分复用模式,例如,将1个高速的数据流分割为几个速率较低的数据流,通过预编码处理然后从不同的天线端口发送。预编码矩阵可以保存于设备中的码本中;码本中包括多个码字,每个码字是一个预编码矩阵。对于上行传输,对应的上述预编码矩阵可以通过TPMI来标识。
本申请实施例涉及的预编码矩阵的系数除实施例中给出的具体系数外,还可以是1,或者其他值。
上述第一TPMI组对应的预编码矩阵集合中可以包括一个预编码矩阵,也可以包括多个预编码矩阵;在此不做限定。上述TPMI组集合中包含的TPMI组的数量在此不做限定,可以是6个TPMI组,也可以是10个TPMI组。可选地,上述TPMI组集合中可以包括至少8个TPMI组。例如,当终端设备采用4比特上报第一TPMI组时(针对终端设备支持4个天线端口的情况),上述TPMI组集合中可以包含16个TPMI组,或者可以包括15个TPMI组,或者其他数目的TPMI组。TPMI组集合至少包括至少8个TPMI组,可以大大提高终端设备在TPMI组集合中选择第一TPMI组时的可选范围,从而使得终端设备能够选择到更加匹配的第一TPMI组进行上报。
上述TPMI组集合中的各个TPMI组中,不同的两个TPMI组可以包含部分相同的预编码矩阵。
上述TPMI组可以适用于不同实现类型的终端设备,上述实现类型可以是支持不同功率架构的终端设备。例如,终端设备具有满功率发送能力时,可以向网络设备上报第一指示信息,上述第一指示信息指示TPMI组集合中相应的一个TPMI组,可选的,第一指示信息同时指示终端设备可以采用上述TPMI组中包含的预编码矩阵实现满功率发送。
可选的,终端设备在向网络设备发送用于指示第一TPMI组的第一指示信息时,可以基于终端设备的天线端口数目以及TPMI组集合,确定第一指示信息指示的第一TPMI组。例如,终端设备支持的天线端口数目为4时,可以根据各天线端口对应的功率能力,在支持4个天线端口的终端设备对应的TPMI组集合中选择第一TPMI组,并通过第一指示信息上报给网络设备。
具体地,终端设备可以通过高层信令向网络设备发送第一指示信息。可选地,终端设备可以通过无线资源控制((Radio Resource Control,简称RRC)信令向网络设备发送第一指示信息;可选的,终端设备可以通过终端能力上报信令向网络设备发送第一指示信息。
上述终端设备可以是支持2个天线端口传输的终端设备,也可以是支持4个天线端口传输的终端设备,还可以是支持其他多个天线端口传输的终端设备,在此不做限定。其中,上述天线端口数目是指逻辑端口的数目,可以等于物理天线端口(或物理天线)的数目,也可以小于物理天线端口的数目。例如,具有4个物理天线端口终端设备,可以支持4个天线端口传输,也可以是将其中两个物理天线端口进行虚拟化之后形成2个天线端口,支持2天线端口传输。在后面描述中,天线端口有时简称为端口,例如2端口传输,4端口终端设备。
终端设备可以根据天线端口数目以及终端设备的相干传输能力,上报上述TPMI组。例如,对于支持4个天线端口的终端设备,在前面通过第一指示信息上报第一TPMI组的基础上,还可以采用2比特的位图(bitmap)来上报第二指示信息,其中每个比特对应1个预编码矩阵,用于指示对应的预编码矩阵能否支持满功率发送;对于上述上报方式,在此不做限定。
另外,终端设备向网络设备发送用于指示第一TPMI组的第一指示信息时,还可以向网络设备上报终端设备支持第一满功率发送模式;第一满功率发送模式用于表征终端设备具有满功率发送能力。
可选地,上述第一满功率发送模式可以通过RRC信令上报,也可以通过终端能力信令上报。
可选地,当终端设备向网络设备上报第一满功率发送模式时,上述第一指示信息的上报方式可以为可选上报。也就是说,当终端设备向网络设备上报第一满功率发送模式时,可选地发送第一指示信息。
可选地,当终端设备向网络设备上报第一满功率发送模式时,上述第一指示信息的上报方式可以为必须上报。也就是说,当终端设备向网络设备上报第一满功率发送模式时,必须同时向网络设备发送第一指示信息。
进一步地,网络设备可以根据接收到的第一满功率发送模式,可以在终端设备发送的第一TPMI组中选择一个TPMI下发给终端设备,也可以在终端设备所对应的码字子集中选择其他一个TPMI下发给终端设备,用于PUSCH传输,在此不做限定。
若网络设备配置终端设备工作在第一满功率发送模式,还可以向终端设备发送探测参考信号资源组配置SRS resource set;其中,上述SRS resource set可以配置至少一个SRS resource,并携带各SRS resource对应的端口数量。各SRS resource对应的端口数量可以相同;可选地,部分或全部SRS resource对应的端口数量可以不同。上述SRS resource可以对应1个端口,也可以对应2个端口;可选地,SRS resource对应的端口数量小于等于4。例如,若上述SRS resource set中携带2个SRS resource,其中一个SRS resource对应的端口数量可以为2,另一个SRS resource对应的端口数量可以为4;若上述SRS resource set中携带4个SRS resource,其中两个SRS resource对应的端口数量可以为1,另外另个SRS resource对应的端口数量可以为2。
上述各SRS resource可以对应同一个空间关系spatial relation information,也可以对应不同的空间关系;可选地,所有SRS resource对应的空间关系的数量小于等于2。可选地,上述SRS resource set用于支持基于codebook的PUSCH传输;其中,SRS resource set对应的usage配置可以是“codebook”。
S102、接收网络设备指示的第一TPMI。
若第一TPMI对应第一TPMI组中的其中一个预编码矩阵,终端设备可以采用第一TPMI对应的目标预编码矩阵进行满功率发送。若第一TPMI不属于第一TPMI组,终端设备采用第一TPMI对应的目标预编码矩阵,根据规定的功率缩放方法进行对应的功率控制。
可选地,若第一TPMI对应的预编码矩阵具有满功率发送能力,终端设备可以采用该第一TPMI对应的目标预编码矩阵进行满功率发送。若第一TPMI不属于第一TPMI组,那么终端设备可以根据规定的功率缩放方法进行对应的功率控制;例如,终端设备采用具有满功率发送能力的第一TPMI获得的缩放系数为1,然后采用该缩放系数进行满功率发送。
终端设备向网络发送第一TPMI组之后,网络设备可以选择一个预编码矩阵,然后通过DCI下发给终端设备,从而使得终端设备基于DCI的预定格式获取DCI指示的目标预编码矩阵。
如果终端设备获取的目标预编码矩阵包含在已上报的第一TPMI组中所对应的预编码矩阵集合中, 终端设备采用该目标预编码矩阵对上行数据进行预编码处理,然后将预编码处理后的上行数据分配至PUSCH非零端口中,进而对预编码处理后的上行数据进行满功率发送。
需要说明的是,终端设备在进行满功率发送时,发射功率是基于网络设备下发的网络配置信息,和/或上行传输对应的调度信息,例如频域资源分配信息、TPC命令等得到的。
具体地,终端设备在进行满功率发送时,可以在上行功率控制过程中,不对计算得到的发射功率进行缩放处理,把计算得到的发送功率分配到PUSCH对应端口,或者采用缩放系数1对计算得到的发射功率进行缩放,把缩放后的发射功率分配到PUSCH对应端口。对于上述满功率发送的实现方式在此不做限定。
上述通信方法,终端设备向网络设备发送第一指示信息,第一指示信息用于指示第一TPMI组,第一TPMI组为TPMI组集合中的一个TPMI组;然后,接收网络设备指示的第一TPMI。当网络设备基于第一TPMI组选择第一TPMI指示给终端设备时,终端设备就可以基于该第一TPMI所对应的目标预编码矩阵进行满功率发送,提高了终端设备的上行覆盖能力,以及终端设备的上行传输性能。
图3为一个实施例中通信方法的流程图。本实施例中的通信方法,以运行于图1中的网络设备为例进行描述。如图3所示,上述通信方法包括以下步骤:
S201、接收终端设备发送的第一指示信息;第一指示信息指示第一预编码矩阵指示符TPMI组,第一TPMI组为TPMI组集合中的一个TPMI组。
S202、向终端设备发送第一TPMI。
