Description

一种传输信号的方法及装置 技术领域
本申请实施例涉及通信领域，尤其涉及一种传输信号的方法及装置。
背景技术
第五代(5th generation，5G)系统或新无线(new radio，NR)系统中的发送端和接收端是基于多输入多输出(multiple-input multiple-output，MIMO)技术通信的。MIMO技术指在发送端和接收端分别使用多个发送天线和接收天线，使信号通过发送端与接收端的多个天线传送和接收，通过多个天线实现多发多收，能充分利用空间资源，在不增加频谱资源和天线发射功率的情况下，可以成倍的提高系统信道容量。
通常，终端支持用于同时接收信号的天线的数量大于或等于用于同时发送信号的天线的数量。例如，终端中设置有2个或更多个天线，终端支持2个天线同时接收信号，所述2个天线中在一个时刻只有一个天线可以发送信号。该方式也可以理解为终端具有1T2R的能力。
针对时分双工(time division duplex，TDD)系统，终端发送参考信号(例如探测参考信号(sounding reference signal，SRS))，获得上行信道状态信息，然后利用信道互异性获得下行信道状态信息。如果终端支持一部分天线同时发送信号，不支持所有天线同时发送信号，则为了获得全信道特性，就需要发送参考信号的天线之间进行切换，多个天线轮流发送参考信号。由此引入天线切换(antenna switching)特性，使得终端可以在一段时间内完成所有天线的参考信号发送。
在UE支持以4T6R的方式传输信号，即终端支持6个天线用于接收信号，6个天线中的4个天线端口用于发送信号的情况下，如何为终端配置资源，以实现全信道测量，并且保证用于测量每个天线端口对应信道的参考信号覆盖相同是需要解决的技术问题。
发明内容
本申请实施例提供一种传输信号的方法及装置，用以实现全信道测量，并且保证用于测量每个天线端口对应信道的参考信号覆盖相同。
第一方面，提供了一种传输信号的方法，首先，终端获取配置信息，然后终端根据所述配置信息，发送参考信号，其中，所述参考信号用于信道测量。其中，所述配置信息用于指示：三个参考信号资源。每个参考信号资源对应2个第一端口，不同的所述参考信号资源对应的第一端口所关联的天线端口不同(不同，即没有交集)；所述三个参考信号资源中的至少两个参考信号资源分别对应的时间单元为相邻的时间单元(相邻，即连续或无保护间隔)。
在上述的第一方面中，终端的6个天线端口对应的信道根据3个参考信号资源配置的3个参考信号测量，每个参考信号资源对应不同的2个天线端口。如果终端为每个参考信号资源分配的传输功率相同，则各个天线端口上的传输功率也相同，从而网络设备接收到参考信号的相对功率可以平衡，可以提高下行信道状态信息估计的准确性。另外，每个天线端口上的传输功率相同，可以保证用于测量每个天线端口的参考信号的覆盖相同(每个 天线端口的参考信号的覆盖相同，也可以理解为用于测量每个天线端口对应信道的参考信号覆盖相同，或者所测量的每个天线端口对应的覆盖相同)。再者，至少两个参考信号资源分别对应的时间单元为相邻的时间单元，终端在连续的时间单元上发送多个参考信号，可以节省时域资源。
在一种可能的实现中，所述三个参考信号资源分别对应的时间单元为相邻的时间单元，该情况可以适用终端支持发送参考信号和天线切换同时发生的情况，可以进一步节省时域资源。

在上述第二方面中，终端的6个天线端口对应的信道根据2个参考信号资源配置的2个参考信号测量。第一参考信号资源对应2个天线端口，第二参考信号资源对应另外的4个天线端口，由于所述第二参考信号资源对应的时间单元的数量为所述第一参考信号资源对应的时间单元的数量的2倍，如果终端为每个参考信号资源分配的传输功率相同，虽然不能达到一个时间单元中每个天线端口上的传输功率相同，但是在多个时间单元中，可以保证每个天线端口上的覆盖相同(即于测量每个天线端口对应信道的参考信号覆盖相同)。
在一种可能的实现中，所述第二参考信号资源对应的重复因子为所述第一参考信号资源对应的重复因子的两倍，和/或，第一参考信号资源对应的每个时间单元上发送参考信号时所占带宽，为所述第二参考信号资源对应的每个时间单元上发送参考信号时所占带宽的两倍或4倍(也就是跳频发送参考信号，第二参考信号资源对应的跳频次数，是第一参考信号资源对应的跳频次数的2倍或4倍)。跳频发送参考信号可以提高分集增益，提高抗干扰的能力。

第三方面，提供了一种传输信号的方法，首先，终端获取配置信息，然后终端根据所述配置信息，发送参考信号，其中，所述参考信号用于信道测量。其中，所述配置信息用于指示：第一参考信号资源、第二参考信号资源和第三参考信号资源。所述第一参考信号资源对应2个第一端口，所述第二参考信号资源对应4个第一端口，所述第三参考信号资源对应4个第一端口。所述第一参考信号资源对应的第一端口所关联的天线端口、与所述第二参考信号资源对应的第一端口所关联的天线端口不同；所述第二参考信号资源对应的第一端口所关联的天线端口、与所述第三参考信号资源对应的第一端口所关联的天线端口相同。所述第一参考信号资源和所述第二参考信号资源分别对应的时间单元为不相邻的时间单元，所述第二参考信号资源和所述第三参考信号资源分别对应的时间单元为相邻的时间单元。
在上述第三方面中，终端的6个天线端口对应的信道根据3个参考信号资源配置的3个参考信号测量。第一参考信号资源对应2个天线端口，第二参考信号资源和第三参考信号资源对应另外的4个天线端口，也就是另外的4个天线端口传输参考信号的时间单元是第一参考信号资源对应的2个天线端口传输参考信号的时间单元的2倍。如果终端为每个参考信号资源分配的传输功率相同，虽然不能达到一个时间单元中每个天线端口上的传输功率相同，但是在多个时间单元中，各个天线端口上总传输功率相同，可以保证每个天线端口上的覆盖相同。
在一种可能的实现中，所述第一参考信号资源、所述第二参考信号资源和所述第三参考信号资源在同一个参考信号资源集中。

具体实施方式
下面将结合附图，对本申请实施例进行详细描述。
为便于理解本申请实施例的技术方案，下面将对本申请实施例提供的方法的系统架构 进行简要说明。可理解的，本申请实施例描述的系统架构是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定。
本申请实施例的技术方案可以应用于各种通信系统，例如：卫星通信系统、传统的移动通信系统。其中，所述卫星通信系统可以与传统的移动通信系统(即地面通信系统)相融合。通信系统例如：无线局域网(wireless local area network，WLAN)通信系统，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)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、第五代(5th generation，5G)系统或新无线(new radio，NR)，第六代(6th generation，6G)系统，以及未来通信系统等。
为便于理解本申请实施例，接下来对本请的应用场景进行介绍，本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
1)介绍本申请适用的通信系统。
如图1所示的通信系统，包括发送端和接收端，发送端和接收端之间可以通过无线电波来进行通信传输，也可以通过可见光、激光、红外、光纤等传输媒介来进行通信传输。在一种示例中，发送端为网络设备，接收端为终端。
网络设备，具有能够为终端设备提供随机接入功能的设备或可设置于该设备的芯片，该设备包括但不限于：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)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)等，还可以为5G，如，NR，系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(DU，distributed unit)等。
终端设备，又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)、终端等，是一种向用户提供语音和/或数据连通性的设备。例如，终端设备包括具有无线连接功能的手持式设备、车载设备等。目前，终端设备可以是：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端(例如，传感器等)、无人驾驶(self-driving)中的无线终端、远程手术(remote medical surgery)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，或智慧家庭(smart home)中的无线终端，或具有车与车(Vehicle-to-Vehicle，V2V就)公共的无线终端等。
2)介绍天线切换与信道测量的关联。
NR系统中的发送端和接收端是基于多输入多输出(multiple-input multiple-output， MIMO)技术通信的。MIMO技术指在发射端和接收端分别使用多个发射天线和接收天线，使信号通过发射端与接收端的多个天线传送和接收，通过多个天线实现多发多收，能充分利用空间资源，在不增加频谱资源和天线发射功率的情况下，可以成倍的提高系统信道容量。
通常，终端支持用于同时接收信号的天线的数量大于或等于用于同时发送天线的数量。例如，终端中设置有2个或更多个天线，终端支持2个天线同时接收信号，所述2个天线中在一个时刻只有一个天线可以发送信号。该方式也可以理解为终端支持以1T2R的方式传输信号，或终端具有1T2R的能力。
针对时分双工TDD系统，终端发送SRS，获得上行信道状态信息，然后利用信道互异性获得下行信道状态信息。如果终端支持一部分天线同时发送信号，不支持所有天线同时发送信号，则为了获得全信道特性，就需要发送信号的天线之间进行切换，多个天线轮流发送参考信号。由此引入天线切换(antenna switching)特性，使得终端可以在一段时间内完成所有天线的参考信号发送。例如，终端在第一个SRS传输机会期间从天线1发送SRS，并且在第二个SRS传输机会期间从天线2发送SRS。
3)接下来介绍天线切换的原理。
终端中设置有一个或多个功率放大器(power amplifier，PA)，一个功率放大器PA可以连接一个天线端口(天线端口与PA之间可能还有其它的元器件，例如移相器，此处进行了省略)，终端可以控制切换功率放大器PA连接的天线端口，与PA连接的天线端口可以发送信号。如图2所示，终端中设置有4个功率放大器PA和6个天线端口。首先，终端控制PA1-PA4分别连接天线端口1-天线端口4，在天线端口1-天线端口4上发送参考信号，则可以测量出天线端口1-天线端口4对应的4个信道的特性。然后，终端控制PA3由连接天线端口3切换为连接天线端口5，控制PA4由连接天线端口4切换为连接天线端口0，在天线端口5和天线端口0上发送参考信号，则可以测量出天线端口5和天线端口0对应的2个信道的特性。
4)接下来介绍网络为终端配置SRS资源。
首先介绍网络为终端配置的SRS-Resource Set的一个示例。
Figure PCTCN2021072318-appb-000001
Figure PCTCN2021072318-appb-000002
Figure PCTCN2021072318-appb-000003
由上，可以看出：终端可以通过高层参数SRS-Resource Set被配置一个或多个SRS资源集，每一个SRS资源集实现的功能通过高层参数SRS-Resource Set中的用例usage被配置。目前的协议版本中支持的usage包括：码本codebook，非码本non Codebook，波束管理beamManagement，以及天线切换antennaSwitching，分别对应基于码本的上行传输、基于非码本的上行传输、上行波束管理以及天线切换这四种功能。对于每一个SRS资源集，终端可以通过高层参数SRS-Resource被配置一个或多个SRS资源。通过srs-ResourceIdList被配置资源集中包含的资源的数量，通过高层参数SRS-Resource中包含的参数nrofSRS-Ports被配置资源对应的SRS端口数，通过各个高层参数SRS-Resource中的startPosition被配置时域资源在一个时隙内的起始位置。
例如，终端向网络设备上报终端支持1T2R。在这种情况下，网络设备为终端最多配 置两个资源类型resourceType不同的SRS资源集，其中，每个SRS资源集中配置两个SRS资源，这两个SRS资源采用不同的符号传输。一个SRS资源集中的每个SRS资源由一个的SRS端口组成，并且该SRS资源集的第二个SRS资源对应的SRS端口所关联的终端的天线端口与第一个SRS资源对应的SRS端口所关联的终端的天线端口不同。
从时域的角度看，一个NR SRS资源集可以通过高层参数资源类型resource Type被配置为周期探测参考信号(periodic SRS，P-SRS)，半持续探测参考信号(semi-persistent SRS，SP-SRS)和非周期探测参考信号(aperiodic SRS，AP-SRS)三种时域行为方式。
此外，UE还会被配置Y个符号的保护间隔，当一个SRS资源集的SRS资源在相同时隙传输时，UE在保护间隔上不传输任何信号。保护间隔在一个资源集的不同资源之间(The UE is configured with a guard period of Y symbols,in which the UE does not transmit any other signal,in the case the SRS resources of a set are transmitted in the same slot.The guard period is in-between the SRS resources of the set)。
Y的取值如表1所示，表1中介绍的是保护间隔的最小符号数，与子载波间隔有关，比如在子载波间隔是15kHz时，保护间隔至少有1个OFDM符号。
表1：最小保护间隔与子载波的关系。
μ Δf＝2 μ·15[kHz] Y[符号]
0 15 1
1 30 1
2 60 1
3 120 2
5)接下来介绍天线端口与天线(即物理天线)的关联。
天线端口是一个逻辑概念，一个天线端口与一个物理天线可以没有直接对应关系，也可以具有关联关系。例如可以规定收发模式为4T6R。天线端口通常和参考信号关联，可以理解为参考信号占用信道上的一个或多个收发接口。对于低频，一个天线端口可能对应一个或多个天线阵元，这些阵元联合发送参考信号，接收端可以把它们当作一个整体，不需要区分这些阵元。对于高频系统，天线端口可能对应着一个波束，接收端只需要将这个波束视为一个接口，不需要区分每个阵元。
6)接下来介绍SRS与传输功率的关联关系。
对于SRS，UE会将传输功率P SRS,b,f,c(i,q s,l)均等地分配到为SRS配置的天线端口上。如果终端基于SRS-ResourceSet的配置，在服务小区c的载波f的上行部分带宽(band width part，BWP)b上用SRS功率控制调整状态l发送SRS，终端在一次SRS发送上通过以下公式确定传输功率P SRS,b,f,c(i,q s,l)(单位为dBm)：
Figure PCTCN2021072318-appb-000004
其中，P CMAX,f,c(i)是UE配置的在服务小区c的载波f上的一次SRS发送i的最大输出功率；P O_SRS,b,f,c(q s)是网络设备想要获得的SRS功率，通过SRS-ResourceSet 中的参数p0配置；q s是指SRS资源集；M SRS,b,f,c(i)是SRS带宽，α SRS,b,f,c(q s)是路损补偿因子，通过SRS-ResourceSet中的参数alpha配置；PL b,f,c(q d)是下行路损估计，通过SRS-ResourceSet中配置的路损参考信号进行测量；h b,f,c(i,l)是闭环功率调整，通过下行控制信息(downlink control information，DCI)进行指示。
由上述公式可知，一个SRS资源集中的每个SRS资源上分配的传输功率相同。当用于天线切换的SRS资源集中的每个SRS资源被配置的SRS端口的数量相同时，对于不同的SRS资源，所有天线端口上的传输功率也相同。
上述介绍了与本申请的技术方案相关的内容，接下来介绍：在UE支持以4T6R的方式传输信号(即终端支持6个天线用于接收信号，6个天线(即天线端口)中的4个天线端口用于发送信号)的情况下，为终端进行资源配置的多个实施例，本申请介绍的多个实施例可以实现全信道测量，并且保证用于测量每个天线端口对应信道的参考信号的覆盖相同(也可以理解为天线端口的覆盖相同)。多个天线端口的覆盖相同，可以理解为多个天线端口分别对应的总传输功率相同，或者多个天线端口对应的资源单元(resource element，RE)上分配的功率相同。
在本申请介绍的任一实施例中，需要注意以下几点：
(1)终端支持4T6R，也就是有6个信道需要测量，在同一时间单元最多只能测量4个信道。
(2)网络设备最多为终端配置两个资源类型resourceType不同(时域行为不同)的SRS资源集。每个参考信号集通过一个或多个高层参数SRS-Resource Set被配置一个或多个SRS资源集，每一SRS资源集实现的功能通过高层参数SRS-Resource Set中的usage被配置。本申请以一个SRS资源集为例进行说明。
(3)“天线端口”为终端的天线端口。“天线端口不同”，可以理解为：天线端口完全不同或没有交集。
(4)一个所述时间单元可以是：一个或多个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号，或者一个或多个子帧，或者一个或多个帧。
(5)“两个参考信号资源之间在时域上相邻”，也可以替换为：两个参考信号资源之间在时域上连续，或两个参考信号资源占用连续的时间单元(例如OFDM符号)，或两个参考信号资源之间不存在保护间隔(guard period，GP)(例如，guard period of Y symbols)，或两个参考信号资源分别对应的时间单元为相邻的时间单元。
例如，时域上依次排列的参考信号资源1和参考信号资源2之间在时域上相邻，可以理解为：参考信号资源1的最后一个OFDM符号和参考信号资源2的第一个OFDM符号之间在时域上相邻，或不存在保护间隔。在本申请中，保护间隔可以是Y个OFDM符号，Y为大于或等于1的整数。保护间隔与参考信号资源对应的时间单元的大小关系不进行限定。OFDM符号仅是一种示例，也可以是其它的能够与OFDM符号等同的时间单元。在本申请中，当一个SRS资源集的SRS资源在相同时隙传输时，UE在保护间隔上不传输任何信号。本申请的SRS资源集中的SRS资源对应的时间单元均为一个时隙中的时间单元。
(6)“两个参考信号资源之间在时域上不相邻”，也可以替换为：两个参考信号资源之间在时域上不连续，或两个参考信号资源占用非连续的时间单元(例如OFDM符号)，或 两个参考信号资源之间存在保护间隔(例如，guard period of Y symbols)，或两个参考信号资源分别对应的时间单元非相邻的时间单元。
接下来将结合附图对方案进行详细介绍，附图中以虚线标识的特征或内容可理解为本申请实施例的可选操作或者可选结构。
实施例1：终端被配置3个参考信号资源，每个参考信号资源对应2个端口，3个参考信号资源中至少两个参考信号资源之间在时域上相邻。
接下来对配置信息进行介绍。
所述配置信息用于指示：三个参考信号资源。
示例的，所述三个参考信号资源在同一个参考信号资源集中。
例如，配置信息包括三组字段，一组字段指示一个参考信号资源。例如，参考信号为SRS。所述配置信息可以承载在无线资源控制(radio resource control，RRC)信令中，所述配置信息可以是高层参数SRS-ResourceSet，SRS-ResourceSet可以配置SRS资源集，并包含参数srs-ResourceIdList；srs-ResourceIdList配置有三个值，即表示资源SRS集中包括三个SRS资源。
示例的，所述配置信息用于天线切换。例如，SRS-ResourceSet中的高层参数usage被配置为antennaSwitching。
示例的，每个参考信号资源对应2个第一端口。
示例的，不同的所述参考信号资源对应的第一端口所关联的天线端口不同。
本申请中的第一端口可以指一类端口，即参考信号端口。例如，第一端口可以是SRS端口(port)。
通常，一个第一端口关联一个天线端口。本申请中的“天线端口不同”，可以理解为：天线端口完全不同或没有交集。如图3a、图3b、和图3c所示的示例，三个参考信号资源中的第一个参考信号资源对应的两个第一端口分别关联天线端口0和天线端口1，第二个参考信号资源对应的两个第一端口分别关联天线端口2和天线端口3，第三个参考信号资源对应的两个第一端口分别关联天线端口4和天线端口5。应理解，图中的“端口”指的是天线端口。此处的第一个、第二个、第三个是指从时域上来说，依次排列的第一个、第二个和第三个。在时域上依次排列的参考信号资源并不是对应ID号依次排列的天线端口。图3a、图3b、图3c中参考信号资源与天线端口的对应关系仅是一种示例，不应造成限定。例如，也可以是第一个参考信号资源对应天线端口3和天线端口4、第二个参考信号资源对应天线端口1和天线端口5、第三个参考信号资源对应天线端口0和天线端口2。应理解，对于图示中横轴来说，代表不同参考信号资源占用的时域位置关系。
在该实施例1中，每个参考信号资源对应的多个第一端口分别关联的天线端口，可以是终端决定的。也就是终端还可以确定每个参考信号资源对应的多个第一端口分别关联的天线端口的标识。
示例的，所述三个参考信号资源中的至少两个参考信号资源之间在时域上相邻。
如图3a所示，提供了一种三个参考信号资源之间在时域上相邻的示例。
如图3b所示，提供了一种三个参考信号资源中的两个参考信号资源之间在时域上相邻的示例。在图3b中，三个参考信号资源中的前两个参考信号资源之间在时域上相邻，第二个参考信号资源和第三个参考信号资源之间在时域上不相邻。
如图3c所示，提供了一种三个参考信号资源中的两个参考信号资源之间在时域上相邻 的示例。在图3c中，三个参考信号资源中的第一个参考信号资源和第二个参考信号资源之间在时域上不相邻，后两个参考信号资源之间在时域上相邻。
可选的，实施例1中，网络设备为终端配置的所述3个参信号资源分别对应的时间单元的数量是相同的，频域资源的带宽值也是相同的。但也不排除时间单元的数量不同、频域资源的带宽值不同的情况。
网络设备可以为终端配置子载波间隔，通常，在子载波间隔小于120kHz时，三个参考信号资源之间都不需要预留保护间隔。当子载波间隔大于或等于120KHz时，保护间隔一般为2个符号，如果配置3个参考信号资源中位于中间的时间单元(在时域上的第二个参考信号资源对应的时间单元)占2个符号时，三个参考信号资源之间可以不需要预留保护间隔，如果配置3个参考信号资源中的位于中间的时间单元(在时域上的第二个参考信号资源对应的时间单元)占1个符号时，即使终端支持发送参考信号和天线切换同时发送，这3个参考信号资源之间也需要额外配置一个符号的保护间隔。
接下来，如图4所示，介绍了一种通信的方法，包括以下步骤：
可选的，步骤401：终端向网络设备发送第一指示信息。相应的，网络设备接收来自终端的第一指示信息。所述第一指示信息用于指示所述终端是否支持三个参考信号资源之间在时域上相邻。
示例的，所述第一指示信息用于指示：所述终端是否支持发送参考信号和天线切换同时发生。
例如，如图2所示，在第一个时间单元上，终端控制PA1和PA2分别连接天线端口0和天线端口1，终端在天线端口0和天线端口1上发送参考信号。在第二个时间单元上，终端控制PA3和PA4分别连接天线端口3和天线端口4，终端在天线端口3上和天线端口4上发送参考信号的同时，也可以将PA1由连接天线端口0切换为连接天线端口5，将PA2由连接天线端口1切换为连接天线端口0。在第三个时间单元上，终端在天线端口5个天线端口0上发送信号。在第二个时间单元上，终端既可以发送参考信号，也进行天线端口的切换，这样，无须预留时间来进行天线切换。
可选的，步骤402：终端向网络设备发送第二指示信息。相应的，网络设备接收来自终端的第二指示信息。所述第二指示信息用于指示：所述终端支持6个天线(具体为6个天线用于接收信号，天线也可以理解为天线端口)，所述6个天线中的4个天线端口用于发送信号。即终端支持以4T6R的方式传输信号，或终端支持4T6R的天线切换能力。
步骤403：网络设备向终端发送配置信息。相应的，终端接收来自网络设备发送的配置信息。
所述配置信息可以参见上文介绍，此处不再重复。
步骤404：终端根据所述配置信息，向网络设备发送参考信号，相应的，网络设备接收来自终端的参考信号，参考信号用于信道测量。此处的参考信号为参考信号资源中配置的参考信号。应理解，步骤404可以单独作为一个实施例，即终端向网络设备发送参考信号，具体的发送方式是以配置信息所配置的方式发送的，在此不再赘述。
进一步地，网络设备可以根据参考信号(例如SRS)进行6个天线端口上的信道测量，以得到下行信道状态信息(channel state information，CSI)。具体的，网络设备确定参考信号接收功率，根据所述参考信号接收功率，计算下行信道状态。
其中，终端根据所述配置信息，发送参考信号，具体可以是：
终端在第一参考信号资源对应的时频资源上，采用所述第一参考信号资源对应的第一端口所关联的天线端口发送参考信号；
终端在第二参考信号资源对应的时频资源上，采用所述第二参考信号资源对应的第一端口所关联的天线端口发送参考信号；
终端在第三参考信号资源对应的时频资源上，采用所述第三参考信号资源对应的第一端口所关联的天线端口发送参考信号。
可以理解的是，在每个参考信号资源对应的时频资源上，有2个天线端口发送参考信号。如图3a、图3b和图3c所示，在第一个参考信号资源对应的时频资源上，天线端口0和天线端口1发送参考信号；在第二个参考信号资源对应的时频资源上，天线端口2和天线端口3发送参考信号；在第三个参考信号资源对应的时频资源上，天线端口4和天线端口5发送参考信号。
另外，第一参考信号资源、第二参考信号资源、第三参考信号资源中有至少两个参考信号资源之间在时域上相邻。可以参见图3a、图3b和图3c，不再重复介绍。
由于UE具有4T能力，所以三个参考信号资源中可以有至少两个参考信号资源之间不需要配置切换时间，即不需要预留Y个符号的保护间隔。进一步地，如果UE具有SRS发送和天线切换同时进行的能力，且发送参考信号的载波的子载波间隔小于120kHz，则三个参考信号资源之间均不需要预留Y个符号的保护间隔。
在实施例1中，终端的6个天线端口对应的信道根据3个参考信号资源配置的3个参考信号测量，每个参考信号资源对应不同的2个天线端口。如果终端为每个参考信号资源分配的传输功率相同，则各个天线端口上的传输功率也相同，从而网络设备接收到参考信号的相对功率可以平衡，可以提高下行信道状态信息估计的准确性。另外，每个天线端口上的传输功率相同，可以保证用于测量每个天线端口的参考信号的覆盖相同(每个天线端口的参考信号的覆盖相同，也可以理解为用于测量每个天线端口对应信道的参考信号覆盖相同)。再者，至少两个参考信号资源分别对应的时间单元为相邻的时间单元，终端在连续的时间单元上发送多个参考信号，可以节省时域资源。
上述介绍的内容是针对4T6R场景的，在非4T6R场景中，例如4T8R、4T10R、6T8R、6T10R场景中，也可以采用与上述介绍的内容类似的方式配置资源。以下仅是针对参考信号资源对应的第一端口的数量，以及在时间单元是否相邻进行介绍，其余内容可以参考上文介绍。
例如，在4T8R场景中，配置信息可以指示4个参考信号资源，每个参考信号资源对应2个第一端口。
在终端支持发送参考信号和天线切换同时发生的情况下，这4个参考信号资源中最多有3个参考信号资源分别对应的时间单元可以是相邻的时间单元，另一个参考信号资源对应的时间单元与这3个相邻的时间单元之间有保护间隔。
在终端不支持发送参考信号和天线切换同时发生的情况下，这4个参考信号资源中，可以每2个参考信号资源分别对应的时间单元可以是相邻的时间单元。
例如，在4T10R场景中，配置信息可以指示5个参考信号资源，每个参考信号资源对应2个第一端口。
在终端支持发送参考信号和天线切换同时发生的情况下，这5个参考信号资源中最多 有3个参考信号资源分别对应的时间单元可以是相邻的时间单元，另外2个参考信号资源分别对应的时间单元也可以是相邻的时间单元。但是这3个相邻的时间单元与这2个相邻的时间单元之间有保护间隔。
在终端不支持发送参考信号和天线切换同时发生的情况下，这5个参考信号资源中，可以每2个参考信号资源分别对应的时间单元可以是相邻的时间单元，剩余一个参考信号资源分别对应的时间单元，与中5个中其它的4个参考信号资源分别对应的时间单元均不相邻。
例如，在6T8R场景中，配置信息可以指示4个参考信号资源，每个参考信号资源对应2个第一端口。
在终端支持发送参考信号和天线切换同时发生的情况下，这4个参考信号资源中最多有4个参考信号资源分别对应的时间单元可以是相邻的时间单元。
在终端不支持发送参考信号和天线切换同时发生的情况下，这4个参考信号资源中最多有3个参考信号资源分别对应的时间单元可以是相邻的时间单元，另一个参考信号资源对应的时间单元与这3个相邻的时间单元之间有保护间隔。
例如，在6T10R场景中，配置信息可以指示5个参考信号资源，每个参考信号资源对应2个第一端口。
在终端支持发送参考信号和天线切换同时发生的情况下，这5个参考信号资源中最多有4个参考信号资源分别对应的时间单元可以是相邻的时间单元，另外一个参考信号资源对应的时间单元与这4个相邻的时间单元之间有保护间隔。
在终端不支持发送参考信号和天线切换同时发生的情况下，这5个参考信号资源中最多有3个参考信号资源分别对应的时间单元可以是相邻的时间单元，另外2个参考信号资源分别对应的时间单元也可以是相邻的时间单元。但是这3个相邻的时间单元与这2个相邻的时间单元之间有保护间隔。
当然，以上示例中，所有的参考信号资源对应的时间单元均可以不相邻。
结合上述示例，可以得到xTyR场景中，配资信息可以指示：y/m个参考信号资源，每个参考信号资源对应m个端口，其中，m为小于或等于x的整数，x为大于或等于2的整数，y为大于或等于2的整数，第一数量的参考信号资源分别对应的时间单元为相邻的时间单元，此处的第一数量为：x/m的向下取整后的值。
实施例2：终端被配置2个参考信号资源，第一参考信号资源对应的2个端口，第二参考信号资源对应4个端口，第二参考信号资源对应的时间单元为第一参考信号资源对应的时间单元的2倍，且第一参考信号资源和第二参考信号资源之间在时域上不相邻。
接下来对配置信息进行介绍。
所述配置信息用于指示：第一参考信号资源和第二参考信号资源。
示例的，所述第一参考信号资源和所述第二参考信号资源在同一个参考信号资源集中。
例如，配置信息包括2组字段，一组字段指示一个参考信号资源。例如，srs-ResourceIdList配置有2个值，即表示SRS资源集中包括2个SRS资源。
示例的，所述配置信息参考信号用于天线切换。例如，SRS-ResourceSet中的高层参数
示例的，所述配置信息参考信号用于天线切换。例如，SRS-ResourceSet中的高层参数usage配置为antennaSwitching。
示例的，第一参考信号资源对应2个第一端口，第二参考信号资源对应4个第一端口。例如，第一参考信号资源的高层参数SRS-Resource中包含的参数nrofSRS-Ports为ports2。第二参考信号资源的高层参数SRS-Resource中包含的参数nrofSRS-Ports为ports4。
示例的，第一参考信号资源对应的第一端口所关联的天线端口与第二参考信号资源对应的第一端口所关联的天线端口不同(不同，即无交集)。
如图5a所示的示例，第一参考信号资源对应的两个第一端口分别关联天线端口0和天线端口1，第二参考信号资源对应的4个第一端口分别关联天线端口2至天线端口5。如图5b所示，第一参考信号资源对应的两个第一端口分别关联天线端口4和天线端口5，第二参考信号资源对应的4个第一端口分别关联天线端口0至天线端口3。图5a和图5b中参考信号资源与天线端口的对应关系仅是一种示例，不应造成限定。在时域上依次排列的参考信号资源并不是对应ID号依次排列的天线端口。
在该实施例2中，每个参考信号资源对应的多个第一端口分别关联哪个天线端口，可以是终端决定的。也就是终端还可以确定每个参考信号资源对应的多个第一端口分别关联的天线端口的标识。
示例的，所述第二参考信号资源对应的时间单元的数量为所述第一参考信号资源对应的时间单元的数量的2倍；所述第一参考信号资源和所述第二参考信号资源之间在时域上不相邻。如图5a和图5b所示，分别提供了一种第一参考信号资源和第二参考信号资源在时域上不相邻的示例。在图5a中，第一参考信号资源对应的时间单元在第二参考信号资源对应的时间单元之前。在图5b中，第二参考信号资源对应的时间单元在第一参考信号资源对应的时间单元之前。
示例的，所述第二参考信号资源对应的重复因子为所述第一参考信号资源对应的重复因子的两倍，则可以实现所述第二参考信号资源对应的时间单元的数量为所述第一参考信号资源对应的时间单元的数量的2倍。“重复因子为两倍”可以由高层参数SRS-Resource中的repetitionFactor确定。这里要注意的是，协议规定或网络设备配置(即配置信息用于指示)，第二参考信号资源对应的重复因子为所述第一参考信号资源对应的重复因子的两倍(即4端口的资源所对应的参数repetitionFactor取值，是2端口的资源对应的参数repetitionFactor取值的两倍)。
在一种示例中，第一参考信号资源对应的频域资源包括至少两个子频域资源，也可以是第一参考信号资源对应的频域资源不进行子频域资源的划分。
在一种示例中，第二参考信号资源对应的频域资源包括至少两个子频域资源。
示例的，第一参考信号资源对应的每个时间单元上发送参考信号时所占带宽，为所述第二参考信号资源对应的每个时间单元上发送参考信号时所占带宽的两倍。(也就是跳频发送参考信号，第二参考信号资源对应的跳频次数，是第一参考信号资源对应的跳频次数的2倍)。跳频发送参考信号可以提高分集增益，提高抗干扰的能力。协议规定或网络设备配置(即配置信息用于指示)，第一参考信号资源对应的每个时间单元上发送参考信号时所占带宽，为所述第二参考信号资源对应的每个时间单元上发送参考信号时所占带宽的两倍。
例如，每个参考信号资源均对应的总的频域资源均为10M，第一参考信号资源对应1 个时间单元a，第二参考信号资源对应2个时间单元b和时间单元c。终端在时间单元a上采用10M带宽发送参考信号，在时间单元b上采用10M带宽中的前5M带宽发送参考信号，在时间单元c上采用10M带宽上的后5M带宽发送参考信号。第一参考信号资源在一个频段上发送参考信号；第二参考信号资源将一个频段分别为两个子频段，在两个子频段上分别发送参考信号。
例如，每个参考信号资源均对应的总的频域资源均为10M，第一参考信号资源对应2个时间单元a和时间单元b，第二参考信号资源对应4个时间单元c、时间单元d、时间单元e和时间单元f。终端在时间单元a上采用10M带宽中的前5M带宽发送参考信号，在时间单元b上采用10M带宽上的后5M带宽发送参考信号。终端在时间单元c、时间单元d、时间单元e和时间单元f上，分别采用10M带宽中的不同的2.5M带宽发送参考信号。第一参考信号资源将一个频段分别为两个子频段，在两个子频段上分别发送参考信号。第二参考信号资源将一个频段分别为四个子频段，在四个子频段上分别发送参考信号。
示例的，第一参考信号资源对应的每个时间单元上发送参考信号时所占带宽，为所述第二参考信号资源对应的每个时间单元上发送参考信号时所占带宽的4倍。例如，每个参考信号资源均对应的总的频域资源均为10M，第一参考信号资源对应2个时间单元a和时间单元b，第二参考信号资源对应4个时间单元c、时间单元d、时间单元e和时间单元f。终端在时间单元a上采用10M带宽发送参考信号，在时间单元b上采用10M带宽发送参考信号。终端在时间单元c、时间单元d、时间单元e和时间单元f上，分别采用10M带宽中的不同的2.5M带宽发送参考信号。第一参考信号资源不对频段进行划分。第二参考信号资源将一个频段分别为四个子频段，在四个子频段上分别发送参考信号。
示例的，第一参考信号资源对应的每个时间单元上发送参考信号时所占带宽，为所述第二参考信号资源对应的每个时间单元上发送参考信号时所占带宽的2倍，且所述第二参考信号资源对应的重复因子为所述第一参考信号资源对应的重复因子的两倍。再例如，每个参考信号资源均对应的总的频域资源均为10M，第一参考信号资源对应2个时间单元a和时间单元b，第二参考信号资源对应4个时间单元c、时间单元d、时间单元e和时间单元f。终端在时间单元a上采用10M带宽中的前5M带宽发送参考信号，在时间单元b上采用10M带宽上的后5M带宽发送参考信号。终端在时间单元c、时间单元d上，分别采用10M带宽中的前5M带宽和后5M带宽分别发送参考信号，终端在时间单元e、时间单元f上，分别采用10M带宽中的前5M带宽和后5M带宽分别发送参考信号。第一参考信号资源将一个频段分别为两个子频段，在两个子频段上分别发送参考信号。第二参考信号资源将一个频段分别为两个子频段，且对这两个子频段进行再次重复。
接下来提供一种适用于实施例2的通信方法，适用于实施例2的通信方法可以与实施例1的通信方法中的步骤401至步骤404相同，重复之处不再赘述。不同之处在于：第一，终端根据所述配置信息，发送参考信号的具体过程(与实施例1类似，可以作为一个单独的实施例)。第二，网络设备接收到参考信号后计算下行信道状态的过程。
接下来介绍终端根据所述配置信息，发送参考信号的具体过程。具体可以是：
终端在第一参考信号资源对应的时频资源上，采用所述第一参考信号资源对应的第一端口所关联的天线端口发送参考信号；
终端在第二参考信号资源对应的时频资源上，采用所述第二参考信号资源对应的第一 端口所关联的天线端口发送参考信号。
可以理解的是，在第一参考信号资源对应的时频资源上，有2个天线端口同时发送参考信号。在第二参考信号资源对应的时频资源上，有4个天线端口同时发送参考信号。第二参考信号资源对应的时间单元的数量为所述第一参考信号资源对应的时间单元的数量的2倍。
如图5a所示，在第一参考信号资源对应的时频资源上，天线端口0和天线端口1发送参考信号，在第二参考信号资源对应的时频资源的前半部分时域资源上，天线端口2-天线端口4发送参考信号，然后再在第二参考信号资源对应的时频资源的后半部分时域资源上，天线端口2-天线端口4再次发送参考信号。
接下来介绍网络设备接收到参考信号之后计算下行信道状态的具体过程。网络设备根据参考信号(例如SRS)进行功率平衡处理(实施例1不需要进行功率平衡处理)；然后，进行6个天线端口上的信道测量，以得到下行CSI。此处的功率平衡处理可以是网络设备对第一参考信号资源对应的参考信号接收功率减少一半。理由为：终端为第一参考信号资源和第二参考信号资源分配的传输功率是相同。由于第一参考信号资源对应2个天线端口，第二参考信号资源对应个4天线端口，则第二参考信号资源对应的每个天线端口上的传输功率是第一参考信号资源对应的每个天线端口上的传输功率的一半。网络设备在计算信道状态信息时，所以需要对第一参考信号资源对应的参考信号接收功率减少一半，然后再根据6个天线端口对应的信道的参考信号的发送功率和接收功率(其中包括第一参考信号资源对应的参考信号接收功率的一半，和第二参考信号资源对应的参考信号接收功率)，准确地计算下行信道状态。
在实施例2中，终端的6个天线端口对应的信道根据2个参考信号资源配置的2参考信号测量。第一参考信号资源对应2个天线端口，第二参考信号资源对应另外的4个天线端口，由于所述第二参考信号资源对应的时间单元的数量为所述第一参考信号资源对应的时间单元的数量的2倍。终端为每个参考信号资源分配的传输功率相同，虽然不能达到一个时间单元中每个天线端口上的传输功率相同，但是在多个时间单元中，各个天线端口上总传输功率相同，可以保证每个天线端口上的覆盖相同(即于测量每个天线端口对应信道的参考信号覆盖相同)。
可选的，在实施例2中，协议可以规定，终端为每个参考信号资源分配的总传输功率相同。也可以是网络设备向终端设备发送第三指示信息，相应的，终端接收来自网络设备的第三指示信息，所述第三指示信息用于指示：每个参考信号资源对应的总传输功率是否相同。
如果指示总传输功率相同，则终端根据现有的方式计算出每个参考信号资源对应的总传输功率后，将总传输功率平均分配给该参考信号资源对应的多个天线端口上，每个天线端口采用被分配的传输功率传输参考信号。对于网络设备来说，需要进行功率平衡处理，即网络设备对第一参考信号资源对应的参考信号接收功率减少一半，然后再计算下行信道状态。
如果指示总的传输功率不同，则终端根据现有的方式计算出每个参考信号资源对应的总传输功率后，先将第一参考信号资源对应的总传输功率减少一半，再将总传输功率的一半平均分配给该第一参考信号资源对应的多个天线端口上，第二参考信号资源对应的总传 输功率平均分配给该第二参考信号资源对应的多个天线端口上，每个天线端口采用被分配的传输功率传输参考信号。或者，终端先将第二参考信号资源对应的总传输功率提升一倍再平分，第一参考信号资源对应的总传输功率直接平分。或者，网络设备为终端配置各个参考信号资源对应的计算总传输功率的相关参数值，使第一参考信号资源对应的总传输功率是第二参考信号资源对应的总传输功率的一半。
或者，协议规定第一参考信号资源按照对应的总传输功率在以下公式的基础上降低3dB的方式计算获得，公式为：
Figure PCTCN2021072318-appb-000005
或者，协议规定第二参考信号资源按照对应的总传输功率在以下公式的基础上升高3dB的方式计算获得。公式为：
Figure PCTCN2021072318-appb-000006
由于终端进行了功率平衡处理，则网络设备无需进行功率平衡处理，网络设备直接根据参考信号接收功率，计算下行信道状态即可。
实施例3：终端被配置3个参考信号资源，第一参考信号资源对应的2个端口，第二参考信号资源和第三参考信号资源均对应4个端口，且第一参考信号资源和第二参考信号资源之间在时域上不相邻，第一参考信号资源和第三参考信号资源在时域上不相邻，第二参考信号资源和第三参考信号资源在时域上可以相邻，也可以不相邻。
接下来对配置信息进行介绍。
所述配置信息用于指示：第一参考信号资源、第二参考信号资源和第三参考信号资源。
示例的，所述第一参考信号资源、第二参考信号资源和第三参考信号资源在同一个参考信号资源集中。
例如，配置信息包括3组字段，一组字段指示一个参考信号资源。例如，srs-ResourceIdList配置有三个值，即表示SRS资源集中包括三个SRS资源。
示例的，所述配置信息用于天线切换。例如，SRS-ResourceSet中的高层参数usage配置为antennaSwitching。
示例的，第一参考信号资源对应2个第一端口，第二参考信号资源和第三参考信号资源均对应4个第一端口。例如，第一参考信号资源的高层参数SRS-Resource中包含的参数nrofSRS-Ports为ports2，第二参考信号资源的高层参数SRS-Resource中包含的参数nrofSRS-Ports为ports4，第三参考信号资源的高层参数SRS-Resource中包含的参数nrofSRS-Ports为ports4。
示例的，第一参考信号资源对应的第一端口所关联的天线端口与第二参考信号资源对应的第一端口所关联的天线端口不同，第二参考信号资源对应的第一端口所关联的天线端口与第三参考信号资源对应的第一端口所关联的天线端口相同。
如图6a所示的示例，第一参考信号资源对应的两个第一端口分别关联天线端口0和天线端口1，第二参考信号资源对应的4个第一端口分别关联天线端口2至天线端口5，第三参考信号资源对应的4个第一端口分别关联天线端口2至天线端口5。如图6b所示，第一参考信号资源对应的两个第一端口分别关联天线端口4和天线端口5，第二参考信号资源对应的4个第一端口分别关联天线端口0至天线端口3，第三参考信号资源对应的4个第一端口分别关联天线端口0至天线端口3。图6a和图6b中参考信号资源与天线端口的对应关系仅是一种示例，不应造成限定。在时域上依次排列的参考信号资源并不是对应ID号依次排列的天线端口。
在该实施例3中，每个参考信号资源对应的多个第一端口分别关联哪个天线端口，可以是终端决定的。也就是终端还可以确定每个参考信号资源对应的多个第一端口分别关联的天线端口的标识。
示例的，所述第一参考信号资源和所述第二参考信号资源之间在时域上不相邻，所述第一参考信号资源和所述第三参考信号资源之间在时域上不相邻，所述第二参考信号资源和所述第三参考信号资源之间在时域上可以相邻，也可以不相邻。上文已经介绍了“相邻”与“不相邻”的含义，此处不再重复赘述。
如图6a所示，分别提供了一种第一参考信号资源在第二参考信号资源和第三参考信号资源之前，且第二参考信号资源和第三参考信号资源在时域上相邻的示例。
如图6b所示，分别提供了一种第一参考信号资源在第二参考信号资源和第三参考信号资源之间，且3个参考信号资源在时域上均不相邻的示例。
在实际应用中，第一参考信号资源也可以在第二参考信号资源和第三参考信号资源之后。
可选的，实施例1中，网络设备为终端配置的所述3个参信号资源分别对应的时间单元的数量是相同的，频域资源的带宽值也是相同的。但也不排除时间单元的数量不同、频域资源的带宽值不同的情况。
由于第二参考信号资源和第三参考信号资源对应相同的4个天线端口，所以当第二参考信号资源和第三参考信号资源在时域上相邻时，无需进行天线端口的切换，可以减少时域资源的占用。
接下来提供一种适用于实施例3的通信方法，适用于实施例3的通信方法可以与实施例1的通信方法中的步骤401至步骤404相同，重复之处不再赘述。不同之处在于：第一，终端根据所述配置信息，发送参考信号的具体过程(与实施例1类似，可以作为一个单独的实施例)。第二，网络设备接收到参考信号后计算下行信道状态的过程。
接下来介绍终端根据所述配置信息，发送参考信号的具体过程。具体可以是：
终端在第一参考信号资源对应的时频资源上，采用所述第一参考信号资源对应的第一端口所关联的天线端口发送参考信号；
终端在第二参考信号资源对应的时频资源上，采用所述第二参考信号资源对应的第一端口所关联的天线端口发送参考信号；
终端在第三参考信号资源对应的时频资源上，采用所述第三参考信号资源对应的第一端口所关联的天线端口(也就是所述第二参考信号资源对应的第一端口所关联的天线端口)发送参考信号。
可以理解的是，在第一参考信号资源对应的时频资源上，有2个天线端口发送参考信号。在第二参考信号资源对应的时频资源上，有4个天线端口发送参考信号。在第三参考信号资源对应的时频资源上，也有4个天线端口发送参考信号。第二参考信号资源对应的时频资源上发送参考信号的4个天线端口与第三参考信号资源对应的时频资源上发送参考信号的4个天线端口相同。
如图6a所示，在第一参考信号资源对应的时频资源上，天线端口0和天线端口1同时发送参考信号，在第二参考信号资源对应的时频资源对应的时域资源上，天线端口2-天线端口4同时发送参考信号，然后再在第三参考信号资源对应的时频资源上，天线端口2-天线端口4再次同时发送参考信号。
接下来介绍网络设备接收到参考信号之后计算下行信道状态的具体过程。网络设备根据参考信号(例如SRS)进行功率平衡处理(实施例1不需要进行功率平衡处理，实施例2中需要进行功率平衡具体过程可以参考实施例2的描述，重复之处不再赘述)；然后，进行6个天线端口上的信道测量，以得到下行CSI。
在实施例3中，终端的6个天线端口对应的信道根据3个参考信号资源配置的2参考信号测量。第一参考信号资源对应2个天线端口，第二参考信号资源和第三参考信号资源对应另外的4个天线端口，也就是另外的4个天线端口传输参考信号的时间单元是第一参考信号资源对应的2个天线端口传输参考信号的时间单元的2倍。终端为每个参考信号资源分配的传输功率相同，虽然不能达到一个时间单元中每个天线端口上的传输功率相同，但是在多个时间单元中，各个天线端口上总传输功率相同，可以保证每个天线端口上的覆盖相同。
在上述的3个实施例中，均是以一个周期为例进行说明的。也就是配置信息中包括的2个或3个参考信号资源，均是一个周期中的参考信号资源，终端上的每个天线端口在任一周期中均能保证覆盖相同。
在接下来的实施例4和实施例5中，以连续的3个周期为例进行说明。终端上的天线端口在连续的3个周期中保证覆盖相同。
实施例4：终端被配置1个周期性的参考信号资源集，每个周期的参考信号资源集中包括2个参考信号资源，第一参考信号资源对应2个第一端口，第二参考信号资源对应4个第一端口，第一参考信号资源和第二参考信号资源分别对应的时间单元为不相邻的时间单元。
接下来对配置信息进行介绍。
在一种方式4.1中，所述配置信息用于指示：参考信号资源集中第一个周期的第一参考信号资源和第二参考信号资源。
示例的，配置信息具体可以指示：第一参考信号资源对应的天线端口标识和/或第二参考信号资源对应的天线端口标识。即使配置信息只配置2个参考信号资源中的一个参考信号资源对应的天线端口标识，另一个参考信号资源对应的天线端口标识也可以推理得到。
此处的第一参考信号资源对应的天线端口标识，可以理解为第一参考信号资源第一端口所关联的天线端口的标识，第二参考信号资源对应的天线端口标识可以理解为第二参考信号资源对应的第一端口所关联的天线端口的标识。
在第一个周期中，第一参考信号资源对应的第一端口所关联的天线端口与第二参考信 号资源对应的第一端口所关联的天线端口不同(没有交集)。例如，第一个周期中的第一参考信号资源对应的天线端口标识分别为天线端口0和天线端口1，第二参考信号资源对应的天线端口标识分别为天线端口2、天线端口3、天线端口4和天线端口5。
可选的，所述配置信息还可以指示天线端口标识的步长值；或者协议规定：天线端口标识的步长值。步长值例如为1、2、3等整数。终端可以根据所述天线端口标识的步长值，以及第一个周期中的第一参考信号资源对应的天线端口标识和/或第二参考信号资源对应的天线端口标识，确定第二个周期和第三个周期中的第一参考信号资源对应的天线端口标识和第二参考信号资源对应的天线端口标识。
例如，如图7a所示，第一个周期中的第一参考信号资源对应的天线端口标识分别为天线端口0和天线端口1，第二参考信号资源对应的天线端口标识分别为天线端口2、天线端口3、天线端口4和天线端口5。在天线端口标识的步长值为2的情况下，则第二个周期中的第一参考信号资源对应的天线端口标识分别为天线端口2和天线端口3，第二参考信号资源对应的天线端口标识分别为天线端口0、天线端口1、天线端口4和天线端口5；则第三个周期中的第一参考信号资源对应的天线端口标识分别为天线端口4和天线端口5，第二参考信号资源对应的天线端口标识分别为天线端口0、天线端口1、天线端口2和天线端口3。
在图7a的示例中，第一参考信号资源在第二参考信号资源之前，当然，第一参考信号资源也可以在第二参考信号资源之后。
再例如，第一个周期中的第一参考信号资源对应的天线端口标识分别为天线端口3和天线端口4，第二参考信号资源对应的天线端口标识分别为天线端口5、天线端口0、天线端口1和天线端口2。在步长值为2的情况下，则第二个周期中的第一参考信号资源对应的天线端口标识分别为天线端口5和天线端口0，第二参考信号资源对应的天线端口标识分别为天线端口1、天线端口2、天线端口3和天线端口4；则第三个周期中的第一参考信号资源对应的天线端口标识分别为天线端口1和天线端口2，第二参考信号资源对应的天线端口标识分别为天线端口3、天线端口4、天线端口5和天线端口0。
在另一种方式4.2中，网络设备为终端配置连续的3个周期中的每个周期中的每个参考信号资源对应的天线端口标识。例如，所述配置信息用于指示：第一个周期中的参考信号资源集中的第一参考信号资源和/或第二参考信号资源分别对应的天线端口标识；第二个周期中的参考信号资源集中的第一参考信号资源和/或第二参考信号资源分别对应的天线端口标识；第三个周期中的参考信号资源集中的第一参考信号资源和/或第二参考信号资源分别对应的天线端口标识。在任一周期中，配置信息可以只配置2个参考信号资源中的一个参考信号资源对应的天线端口标识，另一个参考信号资源对应的天线端口标识也可以推理得到。
在三个周期中的任一个周期中，第一参考信号资源对应的第一端口所关联的天线端口与第二参考信号资源对应的第一端口所关联的天线端口不同(没有交集)。
由上述示例可以看出：不管是方式4.1还是方式4.2，这三个周期中的参考信号资源集中的第一参考信号资源和第二参考信号资源分别对应的天线端口标识中的任一天线端口标识满足以下要求：
在这三个周期中的某一周期中，该天线端口标识为第一参考信号资源对应的天线端口 标识，在剩余的两个周期中，该天线端口标识为第二参考信号资源对应的天线端口标识。也可以理解为两个参考信号资源对应的天线端口标识是循环往复的。
在该实施例4中，终端的6个天线端口对应的信道根据3个周期中的每个周期中的2个参考信号资源配置的2参考信号测量，第一参考信号资源对应2个天线端口，第二参考信号资源对应另外的4个天线端口。如果在任一周期中的任一个时间单元中，终端为每个参考信号资源分配的传输功率相同，虽然不能达到一个周期中每个天线端口上的传输功率相同，但是在3个周期中，各个天线端口上总传输功率相同，可以保证每个天线端口上的覆盖相同。
可选的，在实施例4中，与实施例2类似，协议可以规定，终端为每个参考信号资源分配的总传输功率相同。也可以是网络设备向终端设备发送第三指示信息，相应的，终端接收来自网络设备的第三指示信息，所述第三指示信息用于指示：每个参考信号资源对应的总传输功率是否相同。
如果指示总传输功率相同，则终端根据现有的方式计算出每个参考信号资源对应的总传输功率后，将总传输功率平均分配给该参考信号资源对应的多个天线端口上，每个天线端口采用被分配的传输功率传输参考信号。对于网络设备来说，需要进行功率平衡处理，即网络设备对第一参考信号资源对应的参考信号接收功率减少一半，然后再计算下行信道状态。
如果指示总的传输功率不同，则终端根据现有的方式计算出每个参考信号资源对应的总传输功率后，先将第一参考信号资源对应的总传输功率减少一半，再将总传输功率的一半平均分配给该第一参考信号资源对应的多个天线端口上，第二参考信号资源对应的总传输功率平均分配给该第二参考信号资源对应的多个天线端口上，每个天线端口采用被分配的传输功率传输参考信号。由于终端进行了功率平衡处理，则网络设备无需进行功率平衡处理，网络设备直接根据参考信号接收功率，计算下行信道状态即可。
实施例5：终端被配置1个周期性的参考信号资源集，每个周期的参考信号资源集中包括2个参考信号资源，每个参考信号资源对应的4个端口，第二参考信号资源对应4个端口，第一参考信号资源和第二参考信号资源分别对应的时间单元为不相邻的时间单元。
接下来对配置信息进行介绍。
在一种方式5.1中，所述配置信息用于指示：参考信号资源集中第一个周期中的第一参考信号资源和第二参考信号资源。
示例的，配置信息具体可以指示：第一参考信号资源对应的天线端口标识和第二参考信号资源对应的天线端口标识。
此处的第一参考信号资源对应的天线端口标识，可以理解为第一参考信号资源第一端口所关联的天线端口的标识，第二参考信号资源对应的天线端口标识可以理解为第二参考信号资源对应的第一端口所关联的天线端口的标识。
在第一个周期中，第一参考信号资源对应的4个天线端口标识和第二参考信号资源对应的4个天线端口标识中存在交集。该交集中包括2个天线端口标识。例如，第一个周期中的第一参考信号资源对应的天线端口标识分别为天线端口0、天线端口1、天线端口4和天线端口5，第二参考信号资源对应的天线端口标识分别为天线端口2、天线端口3、天线端口4和天线端口5。该交集中包括天线端口4和天线端口5。
可选的，所述配置信息还可以指示天线端口标识的步长值；或者协议规定：天线端口标识的步长值。步长值例如为1、2、3等整数。终端可以根据所述天线端口标识的步长值，以及第一个周期中的第一参考信号资源对应的天线端口标识和第二参考信号资源对应的天线端口标识，确定第二个周期和第三个周期中的第一参考信号资源对应的天线端口标识和第二参考信号资源对应的天线端口标识。
例如，如图7b所示，第一个周期中的第一参考信号资源对应的天线端口标识分别为天线端口0、天线端口1、天线端口4和天线端口5，第二参考信号资源对应的天线端口标识分别为天线端口2-5。在天线端口标识的步长值为2的情况下，则第二个周期中的第一参考信号资源对应的天线端口标识分别为天线端口0-3，第二参考信号资源对应的天线端口标识分别为天线端口4、天线端口5、天线端口0和天线端口1；则第三个周期中的第一参考信号资源对应的天线端口标识分别为天线端口2-5，第二参考信号资源对应的天线端口标识分别为天线端口0-3。
在图7b的示例中，第一参考信号资源在第二参考信号资源之前，当然，第一参考信号资源也可以在第二参考信号资源之后。
在另一种方式5.2中，网络设备为终端配置连续的3个周期中的每个周期中的每个参考信号资源对应的天线端口标识。例如，所述配置信息用于指示：第一个周期中的参考信号资源集中的第一参考信号资源和第二参考信号资源分别对应的天线端口标识；第二个周期中的参考信号资源集中的第一参考信号资源和第二参考信号资源分别对应的天线端口标识；第三个周期中的参考信号资源集中的第一参考信号资源和第二参考信号资源分别对应的天线端口标识。
不管是方式5.1还是方式5.2，这三个周期中的参考信号资源集中的第一参考信号资源和第二参考信号资源分别对应的天线端口标识满足以下要求：
在三个周期中的任一个周期中，第一参考信号资源对应的第一端口所关联的天线端口与第二参考信号资源对应的第一端口所关联的天线端口存在交集。该交集中包括2个天线端口标识。三个周期对应的3个交集中，天线端口标识没有交集。
在该实施例5中，终端的6个天线端口对应的信道根据3个周期中的每个周期中的2个参考信号资源配置的2参考信号测量，每个参考信号资源对应4个天线端口。如果在任一周期中的任一个时间单元中，终端为每个参考信号资源分配的传输功率相同，虽然不能达到一个周期中每个天线端口上的传输功率相同，但是在3个周期中，各个天线端口上总传输功率相同，可以保证每个天线端口上的覆盖相同。
