图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(VUE)、行人终端(PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer，PC)、柜员机或者自助机等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以包括接入网设备或核心网设备，其中，接入网设备也可以称为无线接入网设备、无线接入网(Radio Access Network，RAN)、无线接入网功能或无线接入网单元。接入网设备可以包括基站、WLAN接入点或WiFi节点等，基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、家用B节点、家用演进型B节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例进行介绍，并不限定基站的具体类型。
为便于理解，先对本申请实施例的应用场景和一些相关技术、概念进行说明。
本申请实施例所提供的技术方案可以应用于频分双工(Frequency Division Duplexing，FDD)和/或时分双工(Time Division Duplexing，TDD)频谱、授权频段和/或非授权频段，单载波和/或多载波等多种场景。
在Rel-18标准中，网络侧灵活/全双工(flexible/full duplex)以及用户/终端侧半双工操作的特点如下：
对于频分双工的对称频谱，也可称为成对频谱，可以半静态配置或动态指示某些时隙/符号上的上行或下行频谱为下行或上行传输，如图2所示，在上行频谱上半静态配置或动态指示填充竖条矩形部分对应的频谱为下行传输(D)，在下行频谱上半静态配置或动态指示填充网格矩形部分对应的频谱为上行传输(U)，其中每个矩形框表示X个时隙或者Y个符号。
对于时分双工的非对称频谱，也可称为非成对频谱，可以半静态配置或动态指示某些时隙/符号上的不同频域资源既有上行传输又有下行传输，如图3所示，在同一时刻，不同频率资源上可以半静态配置或动态指示为下行传输(D)或上行传输(U)，如填充竖条矩形部分对应的频域资源为下行传输，填充网格矩形部分对应的频域资源为上行传输。
对于半双工的终端，在同一时刻只能进行上行发送或者下行接收，即在同一时刻终端不能既接收信号又发送信号，如图4和图5所示，分别对应网络侧的图2和图3。
为了实现灵活的网络部署，NR系统中通过时隙格式(slot format)配置一个时隙中各个符号的传输方向。
NR系统中时隙的传输方向有三种定义：下行(DL)、上行(UL)、灵活(flexible)。当网络配置了一个时隙或符号是DL或UL，则该时刻的传输方向是明确的；当网络配置了一个时隙或符号是flexible，则该时刻的传输方向是待定的。网络可以通过动态信令，如动态的时隙格式指示(slot format indicator，SFI)来对灵活的时隙或符号的传输方向进行修改。
一个时隙可以包含下行、上行和灵活的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号，灵活符号可以被改写为下行或者上行符号。如图6所示，填充竖条矩形部分为下行OFDM符号，填充网格矩形部分为上行OFDM符号，空白矩形部分为灵活OFDM符号。
时隙格式指示可以指示一个或者多个时隙的格式。时隙格式指示在组公共物理下行控制信道(Group Common-Physical Downlink Control Channel，GC-PDCCH)中发送。
时隙格式指示可以灵活地根据需求改变时隙的格式，以满足业务传输需求。
终端可以根据时隙格式指示的指示决定是否监测物理下行控制信道。
网络侧设备，如基站，可以通过高层参数，如UL-DL-configuration-common和UL-DL-configuration-common-Set2(可选的)半静态地给终端配置一个或者多个小区专属(cell-specific)的时隙格式。
网络侧设备，如基站，也可以通过高层参数UL-DL-configuration-dedicated半静态地给终端配置一个或者多个终端专属(UE-specific)的时隙格式。
网络侧设备，如基站，可以通过组公共物理下行控制信道中承载的时隙格式指 示改写半静态配置中的灵活时隙或符号。
由终端专属无线资源控制(Radio Resource Control，RRC)配置隐式指示的传输方向被统称为测量(measurement)，包括：
终端专属的RRC信令配置的周期性或者半持续的信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)测量，周期性的信道状态信息(Channel State Information，CSI)上报，周期性或者半持续的探测参考信号(Sounding Reference Signal，SRS)所隐式指示的上下行传输方向；
终端专属的RRC配置的物理随机接入信道(Physical Random Access Channel，PRACH)资源，type1和type2免授权上行传输；
对type2的免授权上行传输，只有第一个激活的资源上的传输被看做终端专属的数据(UE-specific data)。
终端专属(UE-specific)传输可以包括物理下行控制信道(Physical Downlink Control Channel，PDCCH)、物理上行共享信道(Physical Uplink Shared Channel，PUSCH)、物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的A/N反馈，下行控制信息(Downlink Control Information，DCI)触发的非周期测量等。
上面对本申请实施例的应用场景和一些相关技术、概念进行了说明，下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的信号处理方法进行详细地说明。
S710：终端获得网络侧设备配置的下行参考信号资源。
网络侧设备可以根据下行参考信号传输需求配置下行参考信号资源，在下行参考信号资源上传输下行参考信号。同时，网络侧设备还可以将配置的多个下行频域子带{W1,W2,…,WN}传送给终端。
终端获得网络侧设备配置的下行参考信号资源后，可以继续执行后续步骤的操作。
S720：终端在第一时刻，基于下行参考信号资源上传输的第一下行参考信号，进行信道或干扰测量；其中，每个第一下行参考信号与第二下行参考信号相关，第二下行参考信号对应于下行参考信号资源，每个第一下行参考信号是基于一组频域单元传输的。
在本申请实施例中，终端获得网络侧设备配置的下行参考信号资源后，可以在第一时刻，确定下行参考信号资源上传输的第一下行参考信号，然后基于第一下行参考信号，进行信道或干扰测量。具体的，终端可以基于第一下行参考信号，对包括服务小区和邻区的多个小区进行信道或干扰测量。
第一时刻可以是第一下行参考信号的传输时刻，或者是测量时刻。第一时刻不限于一个时刻，可以是多个时刻。如果第一时刻是第一下行参考信号的传输时刻，则不限定测量是在什么时刻进行，只要测量时基于第一时刻传输的第一下行参考信 号即可。如果第一时刻是测量时刻，则不限定第一下行参考信号的传输是什么时刻，只要是在第一时刻进行的测量，就可以基于第一下行参考信号进行。另外，第一下行参考信号的传输时刻和测量时刻可以是同一时刻，只是从不同角度进行的描述。
下行参考信号资源上传输的每个第一下行参考信号与第二下行参考信号相关，可以是对第二下行参考信号进行拆分得到的。这里的拆分具体可以是分开、划分、分割、分段等。第二下行参考信号对应于下行参考信号资源，每个第一下行参考信号是基于一组频域单元传输的。一组频域单元可以包括一个或多个频域单元，是一段连续的频域资源，比如资源块(Resource Block，RB)、资源粒子(Resource Element，RE)、资源块组(Resource Block Group，RBG)、子带(subband)等。从不同的频域粒度来看，第一下行参考信号的传输在频域上可以是连续的，也可以是不连续的。例如，在资源块上是连续的，在资源粒子上是不连续的。
即将一个第二下行参考信号的传输拆分为一个或多个实际的第一下行参考信号的传输。多个第一下行参考信号可以都属于一个第二下行参考信号，每个第一下行参考信号是第二下行参考信号的一个分段或部分。如果下行参考信号资源是一段连续的频域资源，则只有一个实际的第一下行参考信号传输，且这个第一下行参考信号即为下行参考信号资源对应的第二下行参考信号。
本申请实施例中，第一下行参考信号可以为周期、或半持续、或非周期的下行参考信号；或者，第一下行参考信号可以为跟踪参考信号(Tracking Reference Signal，TRS)、或用于波束管理的信道状态信息参考信号(CSI-RS for beam management)、或用于获取信道状态信息的信道状态信息参考信号(CSI-RS for CSI acquisition)；或者，第一下行参考信号为用于信道/干扰测量的非零功率信道状态信息参考信号(NZP-CSI-RS for channel/interference measurement)、或用于干扰测量的信道状态信息干扰测量信号(CSI-IM for interference measurement)。
应用本申请实施例所提供的方法，在下行参考信号资源上传输一个或多个第一下行参考信号，每个第一下行参考信号均与下行参考信号资源对应的第二下行参考信号相关，这样能够有效地在多个不连续的下行子带上传输与第二下行参考信号相关的第一下行参考信号，不需要过多的配置下行参考信号资源，可以节省下行参考信号资源，避免过多使用下行参考信号资源，避免因下行参考信号资源不足影响下行参考信号的正常传输。
在本申请的一个实施例中，传输每个第一下行参考信号的频域资源是有效的。
可以理解的是，在下行参考信号资源上用于传输下行参考信号的频域资源需要是有效的，而下行参考信号资源包括的频域资源可能并不都是有效的，比如下行参考信号资源包括的指示为上行传输的频域资源就是非有效频域资源，无法进行下行参考信号的传输，即需要在有效的频域资源上传输每个第一下行参考信号。这样可以保证下行参考信号的正常传输。
在本申请的一个实施例中，下行参考信号资源的频域单元是否为有效频域资源是按照以下至少一项规则确定的：
由灵活双工上下行配置指示为上行或灵活的频域单元，不是传输下行参考信号的有效频域资源；
由灵活双工上下行配置指示为上行或灵活的频域单元，如果网络侧设备指示为用于下行传输，则是传输下行参考信号的有效频域资源；
由随机接入资源配置指示为用于随机接入的频域单元，不是传输下行参考信号的有效频域资源；
由保护带配置指示为用于保护带的频域单元，不是传输下行参考信号的有效频域资源；
由网络侧设备配置的无效资源块样式或速率匹配样式指示为非可用的频域单元，不是传输下行参考信号的有效频域资源。
在本申请实施例中，可以预定义规则，用于确定下行参考信号资源的频域单元是否有效。下行参考信号资源可以包括多个频域单元，频域单元可以是子带、资源粒子、资源块、带宽部分(bandwidth part，BWP)等粒度的频域资源。
具体的，该预定义规则可以包括以下至少一项：
第一规则：由灵活双工上下行配置指示为上行或灵活的频域单元，不是传输下行参考信号的有效频域资源。即对于被指示为上行或灵活的频域单元，不能作为传输下行参考信号的有效频域资源，该频域单元为非有效频域资源。
灵活双工上下行配置可以是时分双工上下行配置(TDD-UL-DL-Configuration)或者频分双工上下行配置(FDD-UL-DL-Configuration)。可以是网络高层配置的，例如通过终端专属信令配置的，或者通过广播信令配置的。
第二规则：由灵活双工上下行配置指示为上行或灵活的频域单元，如果网络侧设备指示为用于下行传输，则是传输下行参考信号的有效频域资源。即对于被指示为上行或灵活的频域单元，如果用于下行传输，则可以作为下行参考信号传输的有效频域资源。
第三规则：由随机接入资源配置指示为用于随机接入的频域单元，不是传输下行参考信号的有效频域资源。即如果频域单元被指示为用于随机接入，则其不能再用于传输下行参考信号，不能作为传输下行参考信号的有效频域资源，该频域单元为非有效频域资源。
第四规则：由保护带(Guardband)配置指示为用于保护带的频域单元，不是传输下行参考信号的有效频域资源。即如果频域单元被指示为用于保护带，则其不能再用于传输下行参考信号，不能作为传输下行参考信号的有效频域资源，该频域单元为非有效频域资源。
第五规则：由网络侧设备配置的无效资源块样式(invalid RB pattern)或速率匹 配样式(Rate Match Pattern)指示为非可用的频域单元，不是传输下行参考信号的有效频域资源。即如果频域单元被无效资源块样式或者速率匹配样式指示为非可用，则其不能再用于传输下行参考信号，不能作为传输下行参考信号的有效频域资源，该频域单元为非有效频域资源。速率匹配样式用于指示物理下行共享信道进行速率匹配。
以上自定义规则可以单独使用，还可以联合使用，根据以上至少一项规则方便终端准确确定下行参考信号资源的频域单元是否为有效频域资源，进而可以准确确定出下行参考信号资源上传输的第一下行参考信号，以基于第一下行参考信号进行信道或干扰测量。
另外，还有一个预定义规则，即对于单端口的下行参考信号资源，不期望存在非有效的频域单元。也就是说，如果下行参考信号资源配置为单端口，则其包括的频域单元应该均为有效频域资源。
根据以上预定义规则可以准确确定下行参考信号资源的频域单元是否为有效频域资源。具体的，可以直接基于以上预定义规则确定出下行参考信号资源中的有效频域资源，还可以基于以上预定义规则确定出下行参考信号资源中的非有效频域资源，然后排除掉非有效频域资源后将剩余的频域资源确定为有效频域资源。
在本申请的一个实施例中，第一下行参考信号的数量为M，M为正整数，M是根据以下至少一种方式确定的：
根据网络侧设备的配置确定；
根据网络侧设备配置的第二下行参考信号包含的第一下行参考信号的最大传输数量确定；
根据下行频域子带的数量确定。
在本申请实施例中，第一下行参考信号与下行参考信号资源对应的第二下行参考信号相关，第一下行参考信号是下行参考信号资源上实际传输的信号，第一下行参考信号的数量可以为M。即一个第二下行参考信号传输可以被拆分成M个实际的第一下行参考信号传输，每个实际的第一下行参考信号传输包括一组频域单元。
可以根据网络侧设备的配置确定第一下行参考信号的数量。具体的，可以将网络侧设备配置的数量确定为第一下行参考信号的数量。
或者，可以根据网络侧设备配置的第二下行参考信号包含的第一下行参考信号的最大传输数量确定。即网络侧设备可以配置第二下行参考信号包含的第一下行参考信号的最大传输数量，根据该最大传输数量可以确定第一下行参考信号的数量，第一下行参考信号的数量小于或等于该最大传输数量。
或者，可以根据下行频域子带的数量确定。下行频域子带可用于传输下行参考信号，第一下行参考信号的数量小于或等于下行频域子带的数量。
根据以上至少一种方式可以有效确定第一下行参考信号的数量，以基于第一下 行参考信号进行信道或干扰测量。
在本申请的一个实施例中，传输每个第一下行参考信号的频域资源包括的频域单元数大于或等于预设的第一数量阈值；
或者，传输每个第一下行参考信号的频域资源包括的频域单元数与下行参考信号资源包括的频域单元数的比例大于或等于预设的比例阈值。
在本申请实施例中，可以对传输第一下行参考信号的频域资源包括的频域单元数进行限定。具体的，针对每个第一下行参考信号，传输该第一下行参考信号的频域资源包括的频域单元数需大于或等于预设的第一数量阈值，或者，传输该第一下行参考信号的频域资源包括的频域单元数与下行参考信号资源包括的频域单元数的比例需大于或等于预设的比例阈值。第一数量阈值和比例阈值均可根据实际情况进行设定和调整。
对传输每个第一下行参考信号的频域资源包括的频域单元数进行限定，可以避免传输每个第一下行参考信号的频域资源包括的频域单元数过少，导致传输的第一下行参考信号信息量太少，使得基于这样的第一下行参考信号进行信道或干扰测量无法获得准确的信道状态信息。
在本申请的一个实施例中，下行参考信号资源上传输的每个第一下行参考信号对应的码分复用类型、频域密度、端口数中至少一项相同。
在本申请实施例中，下行参考信号资源上传输的每个第一下行参考信号对应的码分复用类型(CDM-type)、频域密度(density)、端口数(Number of ports)中至少一项相同，且每个第一下行参考信号对应的码分复用类型、频域密度、端口数中至少之一与第二下行参考信号对应的参数相同。以保证第一下行参考信号与第二下行参考信号的相关性。
为方便理解，以图8所示的CSI-RS传输为例，对本申请实施例进行说明。
网络侧设备配置的时频域资源如图8所示，D代表下行资源，U代表上行资源，GB代表保护带，GP代表保护间隔，区域A代表CSI-RS的不可用资源块(Invalid RBs)。
网络侧设备配置1个CSI-RS资源配置，分别包括CSI-RS 1资源和CSI-RS 2资源，对应的频域资源都为f0～f5。CSI-RS资源可以是周期CSI-RS资源或非周期CSI-RS资源。
slot t0、slot t1和slot t2是CSI的测量时刻。
在slot t0，所有频域资源均为DL频域资源，终端根据预定义规则，可以确定所有频域资源是CSI-RS 1资源和CSI-RS 2资源的有效频域资源，即频域资源f0～f5。所以，在slot t0，CSI-RS 1资源上有CSI-RS 1传输，CSI-RS 2资源上有CSI-RS 2传输。
在slot t1，终端根据预定义规则，可以确定上行频域资源和保护带频域资源为传 输CSI-RS的非有效频域资源，即频域资源f2～f3为传输CSI-RS的非有效频域资源。所以，在slot t1，CSI-RS 1资源上的CSI-RS传输拆分成两个实际的CSI-RS传输，分别为在f0～f2的CSI-RS 1’-1传输和在f3～f5的CSI-RS 1’-2传输；CSI-RS 2资源上的CSI-RS传输拆分成两个实际的CSI-RS传输，分别为在f0～f2的CSI-RS 2’-1传输和在f3～f5的CSI-RS 2’-2传输。
在slot t2，终端根据预定义规则，可以确定上行频域资源和保护带频域资源为传输CSI-RS的非有效频域资源，即频域资源f1～f4为传输CSI-RS的非有效频域资源。所以，在slot t1，CSI-RS 1资源上的CSI-RS传输拆分成两个实际的CSI-RS传输，分别为在f0～f1的CSI-RS 1”-1传输和在f4～f5的CSI-RS 1”-2传输；CSI-RS 2资源上的CSI-RS传输拆分成两个实际的CSI-RS传输，分别为在f0～f1的CSI-RS 2”-1传输和在f4～f5的CSI-RS 2”-2传输。
本申请实施例中，当终端在不同时刻有不同的频域资源格式，需要对每个时刻对应的下行频域带宽进行CSI测量，可以根据传输CSI-RS的有效频域资源确定实际的CSI-RS传输，不需要在每个下行频域子带配置不同的CSI-RS资源，能够节省开销。
上面是基于预定义规则确定下行参考信号资源上传输的第一下行参考信号，下面从另一种网络侧设备配置角度考虑对下行参考信号资源上传输的第一下行参考信号进行确定。
在本申请的一个实施例中，传输每个第一下行参考信号的频域资源是根据网络侧设备的资源配置信息确定的。
在本申请实施例中，网络侧设备可以对下行参考信号资源包括的频域资源进行配置，将资源配置信息发送给终端。终端根据网络侧设备的资源配置信息可以确定传输每个第一下行参考信号的频域资源。
根据网络侧设备的资源配置信息，有助于终端准确确定传输每个第一下行参考信号的频域资源，进而确定下行参考信号资源上实际传输的第一下行参考信号。
在本申请的一个实施例中，资源配置信息可以包括下行参考信号资源对应的频域资源集，频域资源集可以包括一个或多个频域资源子集。
在本申请实施例中，资源配置信息可以包括下行参考信号资源对应的频域资源集，频域资源集可以包括一个或多个频域资源子集。以下行参考信号资源为信道状态信息参考信号资源，即CSI-RS资源为例，对于一个CSI-RS资源，可以配置频域资源集{FCSI-RS}，该频域资源集{FCSI-RS}包含一个或多个频域资源子集，如{FD,FX}。
根据资源配置信息可以准确确定传输每个第一下行参考信号的频域资源，进而可以确定下行参考信号资源上传输的第一下行参考信号，以基于第一下行参考信号进行信道或干扰测量。
在本申请的一个实施例中，频域资源集可以包括第一频域资源子集，第一频域 资源子集对应于第一时域单元；
其中，第一时域单元满足以下至少一项：
对应于时域格式为下行/灵活的时域资源；
对应于资源配置信息给定编号的时域资源；
仅包含下行频域资源。
在本申请实施例中，频域资源集可以包括第一频域资源子集，第一频域资源子集对应于第一时域单元。即在第一时域单元，下行参考信号资源对应的频域资源集包括第一频域资源子集，如{FD}。
具体的，第一时域单元可以对应时域格式为下行/灵活(DL/Flexible)的时域资源；第一时域单元还可以对应于资源配置信息给定编号的时域资源，给定编号的时域资源可以是时域格式为下行/灵活的时域资源，还可以是其他时域格式的时域资源；第一时域单元还可以仅包含下行频域资源。
根据以上至少一项，可以准确确定出频域资源集包括的第一频域资源子集对应的第一时域单元，进而可以在第一时域单元基于第一频域资源子集确定传输第一下行参考信号的频域资源，以进一步确定下行参考信号资源上实际传输的第一下行参考信号，基于第一下行参考信号进行信道或干扰测量。
在本申请的一个实施例中，频域资源集包括第二频域资源子集，第二频域资源子集对应于第二时域单元；
其中，第二时域单元满足以下至少一项：
对应于时域格式为下行/灵活/上行的时域资源；
对应于资源配置信息给定编号的时域资源；
包含下行频域资源和上行频域资源。
在本申请实施例中，频域资源集可以包括第二频域资源子集，第二频域资源子集对应于第二时域单元。即对于第二时域单元，下行参考信号资源对应的频域资源集包括第二频域资源子集，如表示为{FX}。
具体的，第二时域单元可以对应于时域格式为下行/灵活/上行(DL/Flexible/UL)的时域资源；第二时域单元还可以对应于资源配置信息给定编号的时域资源，给定编号的时域资源可以是时域格式为下行/灵活/上行的时域资源，还可以是其他时域格式的时域资源；第二时域单元还可以同时包含下行频域资源和上行频域资源。
根据以上至少一项，可以准确确定出频域资源集包括的第二频域资源子集对应的第二时域单元，进而可以在第二时域单元基于第二频域资源子集确定传输第一下行参考信号的频域资源，以进一步确定下行参考信号资源上实际传输的第一下行参考信号，基于第一下行参考信号进行信道或干扰测量。
在本申请的一个实施例中，频域资源集可以包括第三频域资源子集；
其中，第三频域资源子集包括起始频域单元、长度、起始偏移值集合；
或者，第三频域资源子集包括起始频域单元集合、长度；
或者，第三频域资源子集包括每个频域资源分配的起始频域单元和长度。
在本申请实施例中，频域资源集可以包括第三频域资源子集，第三频域资源子集可以是第一频域资源子集或者第二频域资源子集。比如，第三频域资源子集是第二频域资源子集，对于下行参考信号资源在第二时域单元的频域资源子集{FX}，可以包含一个或多个频域资源分配{FX,1,FX,2,…,FX,M}。
第三频域资源子集可以包括起始频域单元、长度、起始偏移值集合，起始偏移值集合如{起始偏移值1,起始偏移值2,…,起始偏移值M}。根据起始频域单元和长度可以确定第一个频域资源分配，根据起始频域单元、长度、起始偏移值集合，可以确定第一个频域资源分配后的每个频域资源分配。举例而言，起始频域单元为f0，长度为f，起始偏移值集合为{f1,f2}，每个频域资源分配分别为：f0～f0+f、f0+f1～f0+f1+f、f0+f2～f0+f2+f。
第三频域资源子集还可以包括起始频域单元集合、长度，起始频域单元集合如{起始频域单元1,起始频域单元2,…,起始频域单元M}。根据起始频域单元集合、长度，可以确定每个频域资源分配。举例而言，起始频域单元集合为{f1,f2,f3}，长度为f，每个频域资源分配分别为：f1～f1+f、f2～f2+f、f3～f3+f。
第三频域资源子集还可以包括每个频域资源分配的起始频域单元和长度，如{(起始频域单元1,长度1),(起始频域单元2,长度2),…,(起始频域单元M,长度M)}。根据每个频域资源分配的起始频域单元和长度，可以确定每个频域资源分配，如第一个频域资源分配为起始频域单元1～起始频域单元1+长度1，第二个频域资源分配为起始频域单元2～起始频域单元2+长度2，以下类同，不再赘述。
根据第三频域资源子集的上述形式，可以快速确定在第一时域单元或第二时域单元下行参考信号资源包括的频域资源分配。
以上确定频域资源子集的方式可以是网络侧设备配置的，还可以是协议约定的。
在本申请的一个实施例中，可以通过以下至少之一确定下行参考信号资源在第二频域资源子集包含的频域资源分配是否传输：
针对第二频域资源子集包含的每个频域资源分配，如果当前频域资源分配与时域格式为灵活/上行的时域资源冲突，则确定下行参考信号资源在当前频域资源分配上不传输；
针对第二频域资源子集包含的每个频域资源分配，如果当前频域资源分配与上行频域资源冲突，则确定下行参考信号资源在当前频域资源分配上不传输。
在本申请实施例中，第二频域资源子集可以包括一个或多个频域资源分配，下行参考信号资源在每个频域资源分配上是否传输下行参考信号可以通过以下至少一项进行确定：
针对第二频域资源子集包含的每个频域资源分配，如果当前频域资源分配与时 域格式为灵活/上行(Flexible/UL)的时域资源冲突，则确定下行参考信号资源在当前频域资源分配上不传输。当前频域资源分配是指当前操作所针对的频域资源分配，如表示为{FX,K}。时域格式为灵活/上行的时域资源可能用于进行上行传输，如果当前频域资源分配与时域格式为灵活/上行的时域资源冲突，则可以确定下行参考信号资源在该当前频域资源上不传输下行参考信号。
针对第二频域资源子集包含的每个频域资源分配，如果当前频域资源分配与上行频域资源冲突，则确定下行参考信号资源在当前频域资源分配上不传输。当前频域资源分配是指当前操作所针对的频域资源分配，如表示为{FX,K}。上行频域资源需用于进行上行传输，如果当前频域资源分配与上行频域资源冲突，则可以确定下行参考信号资源在该当前频域资源上不传输下行参考信号。
进一步的，针对第二频域资源子集包含的每个频域资源分配，如果当前频域资源分配与时域格式为下行/灵活/上行的时域资源上的上行频域资源冲突，则可以确定下行参考信号资源在该当前频域资源上不传输。
通过以上至少一项可以准确确定出下行参考信号资源在第二频域资源子集包括的每个频域资源分配上是否传输下行参考信号。
为方便理解，以图9所示的CSI-RS传输为例，对本申请实施例进行说明。
网络侧设备配置的时频域资源如图9所示，D代表下行资源，U代表上行资源，GB代表保护带，GP代表保护间隔。
网络侧设备配置三个CSI-RS资源配置，分别为CSI-RS资源配置1、CSI-RS资源配置2和CSI-RS资源配置3，其中：
CSI-RS资源配置1分别包括CSI-RS 1资源和CSI-RS 2资源，频域资源都为f0～f5；
CSI-RS资源配置2分别包括CSI-RS 3资源和CSI-RS 4资源。CSI-RS 3资源包含两个频域资源分配{F3-1,F3-2}，分别为：{F3-1}＝f0～f2和{F3-2}＝f3～f5；CSI-RS 4资源包含两个频域资源分配{F4-1,F4-2}，分别为：{F4-1}＝f0～f2和{F4-2}＝f3～f5。
CSI-RS资源配置3分别包括CSI-RS 5资源和CSI-RS 6资源。CSI-RS 5资源包含两个频域资源分配{F5-1,F5-2}，分别为：{F5-1}＝f0～f1和{F5-2}＝f4～f5；CSI-RS 6资源包含两个频域资源分配{F6-1,F6-2}，分别为：{F6-1}＝f0～f1和{F6-2}＝f4～f5。
CSI-RS资源可以是周期CSI-RS资源或非周期CSI-RS资源。slot t0、slot t1和slot t2是CSI的测量时刻。
在slot t0，CSI-RS 1资源上有CSI-RS 1传输，CSI-RS 2资源上有CSI-RS 2传输。
在slot t1，CSI-RS 3资源的频域资源f0～f2上有CSI-RS 3-1’传输，频域资源f3～f5上有CSI-RS 3-2’传输；CSI-RS 4资源的频域资源f0～f2上有CSI-RS 4-1’传输，频域资源f3～f5上有CSI-RS 4-2’传输。
在slot t2，CSI-RS 5资源的频域资源f0～f1上有CSI-RS 5-1’传输，频域资源f4～f5 上有CSI-RS 5-2’传输；CSI-RS 6资源的频域资源f0～f1上有CSI-RS 6-1’传输，频域资源f4～f5上有CSI-RS 6-2’传输。
本申请实施例中，当终端在不同时刻有不同的频域资源格式，需要对每个时刻对应的下行频域带宽进行CSI测量，可以根据多个频域资源分配确定实际的CSI-RS传输，不需要在每个下行频域子带配置独立的CSI-RS资源，能够节省开销。
需要说明的是，在相关技术中，在下行子带发生变化时需要重新配置下行参考信号资源，造成额外的信令开销，本申请实施例无论是基于预定义规则还是基于网络侧设备的资源配置信息，进行实际传输的第一下行参考信号的确定，都具有一定的灵活性，在下行子带发生变化时不需要重新配置下行参考信号资源，节省了信令开销。
在本申请的一个实施例中，该方法还可以包括以下步骤：
终端向网络侧设备上报信道或干扰测量对应的信道状态信息。
终端在第一时刻，基于下行参考信号资源上传输的第一下行参考信号，进行信道或干扰测量后，可以获得信道或干扰测量对应的信道状态信息，终端可以向网络侧设备上报信道或干扰测量对应的信道状态信息。
这样网络侧设备可以基于信道状态信息进行波束管理、终端调度等操作。
在本申请的一个实施例中，终端的上报方式为基于宽带的上报；
第一下行参考信号的数量为M，信道或干扰测量对应的信道状态信息包括K个第一信道状态信息，K<＝M；
其中，每个第一信道状态信息包括第一宽带信道状态信息，和/或每个第一信道状态信息分别对应一个或多个第一下行参考信号。
在本申请实施例中，终端向网络侧设备上报信道或干扰测量对应的信道状态信息时，其上报方式可以是基于宽带的上报。下行参考信号资源上传输的第一下行参考信号是实际的下行参考信号传输，第一下行参考信号的数量可以为M。终端可以基于每个第一下行参考信号或者多个第一下行参考信号进行信道或干扰测量，得到相应的信道状态信息。
信道或干扰测量对应的信道状态信息可以包括K个第一信道状态信息，K<＝M。
因为终端的上报方式为基于宽带的上报，所以每个第一信道状态信息可以包括第一宽带信道状态信息，每个第一信道状态信息可以分别对应一个或多个第一下行参考信号。
终端基于多个第一下行参考信号进行信道或干扰测量，得到相应的信道状态信息，并分别上报宽带信道状态信息，可以使得网络侧设备能够得到更准确的信道状态。
在本申请的一个实施例中，终端的上报方式为基于子带的上报；
第一下行参考信号的数量为M，信道或干扰测量对应的信道状态信息包括L个 第二信道状态信息，L<＝M；
每个第二信道状态信息包括第二宽带信道状态信息和子带信道状态信息；
每个第二宽带信道状态信息对应一个或多个第一下行参考信号；
每个子带信道状态信息对应信道状态信息上报频带中的一个子带，每个子带对应一个或多个第一下行参考信号；其中，信道状态信息上报频带对应信道或干扰测量对应的信道状态信息。
在本申请实施例中，终端向网络侧设备上报信道或干扰测量对应的信道状态信息时，其上报方式可以是基于子带的上报。下行参考信号资源上传输的第一下行参考信号是实际的下行参考信号传输，第一下行参考信号的数量可以为M。终端可以基于每个第一下行参考信号或者多个第一下行参考信号进行信道或干扰测量，得到相应的信道状态信息。
信道或干扰测量对应的信道状态信息可以包括L个第二信道状态信息，L<＝M。每个第二信道状态信息可以包括第二宽带信道状态信息和子带信道状态信息。每个第二宽带信道状态信息对应一个或多个第一下行参考信号，每个子带信道状态信息可以与信道状态信息上报频带中的一个子带相对应，每个子带对应于一个或多个第一下行参考信号。这里的信道状态信息上报频带对应信道或干扰测量对应的信道状态信息。信道状态信息上报频带可以是根据下行频域资源确定的，也可以是网络侧设备配置在下行频域资源内的。
需要说明的是，第二信道状态信息包括的第二宽带信道状态信息对应信道状态信息上报频带中的一个或多个子带，第二信道状态信息包括的子带信道状态信息是根据该第二信道状态信息包括的第二宽带信道状态信息得到的。
举例而言，终端配置了子带信道状态信息(subband CSI)上报。下行子带(DL subband)数为2，下行参考信号资源对应的第二下行参考信号拆分成M＝2个实际的第一下行参考信号传输，如CSI-RS传输1-1和CSI-RS传输1-2。在DL subband 1，终端基于CSI-RS传输1-1进行信道或干扰测量，上报宽带CSI 1+DL subband 1上的subband CSI；在DL subband 2，终端基于CSI-RS传输1-2进行信道或干扰测量，上报宽带CSI 2+DL subband 2上的subband CSI。
终端基于子带上报方式上报信道或干扰测量对应的信道状态信息，可以提高上报精准度。
在本申请的一个实施例中，终端的上报方式为基于子带的上报，第一下行参考信号的数量为M，终端向网络侧设备上报信道或干扰测量对应的信道状态信息，可以包括以下步骤：
终端在传输M个第一下行参考信号的频域资源包括的频域单元总数小于预设的第二数量阈值的情况下，向网络侧设备上报单个宽带信道状态信息，或者向网络侧设备上报P个宽带信道状态信息，不上报子带信道状态信息，P<＝M。
可以理解的是，传输M个第一下行参考信号的频域资源包括的频域单元总数越多，对信道或干扰的测量越准确。所以，在传输M个第一下行参考信号的频域资源包括的频域单元总数小于第二数量阈值时，可以向网络侧设备上报单个宽带信道状态信息，可以对应整个信道状态信息上报频带的带宽。或者，在上述情况下，终端还可以向网络侧设备上报P个宽带信道状态信息，不上报子带信道状态信息。
这样可以有效保证上报的信道状态信息的准确性。
在本申请的一个实施例中，在终端向网络侧设备上报信道或干扰测量对应的信道状态信息之前，该方法还包括：
终端根据传输每个第一下行参考信号的频域资源，确定上报频带；
终端向网络侧设备上报信道或干扰测量对应的信道状态信息，包括：
终端基于上报频带，向网络侧设备上报信道或干扰测量对应的信道状态信息。
在本申请实施例中，终端可以根据传输每个第一下行参考信号的频域资源，确定上报频带。具体的，可以分别将每个传输第一下行参考信号的频域资源确定为上报频带，或者将多个传输第一下行参考信号的频域资源确定为上报频带。然后基于该上报频带，向网络侧设备上报信道或干扰测量对应的信道状态信息。
具体的，如果终端的上报方式为基于宽带的上报，第一下行参考信号的数量为M，则终端可以向网络侧设备上报该上报频带对应的宽带信道状态信息，宽带信道状态信息对应于M个第一下行参考信号；
或者，终端可以向网络侧设备上报该上报频带对应的M个宽带信道状态信息，每个宽带信道状态信息分别对应一个第一下行参考信号。
本申请实施例还可以对下行参考信号进行功率控制(power control)。以下行参考信号为CSI-RS为例，对于一个实际的CSI-RS传输，实际的CSI-RS资源粒子(Resource element，RE)相对于辅同步信号(Secondary Synchronization Signals，SSS)RE的功率偏移(Power offset)OffsetB可以根据至少一项来确定：
该CSI-RS传输所占带宽Wx；
CSI-RS资源的总带宽W；
实际CSI-RS传输的总数量M。
如，
OffsetB＝OffsetA；
或，OffsetB＝Wx*OffsetA/W；
或，OffsetB＝W*OffsetA/M/Wx。
其中，OffsetA是在CSI-RS传输不拆分时，CSI-RS RE相对于SSS RE的功率偏移。
对于一个实际的CSI-RS传输，PDSCH RE相对于实际的CSI-RS RE的功率偏移OffsetD可以根据以下至少一项来确定：
该CSI-RS传输所占带宽Wx；
CSI-RS资源的总带宽W；
实际CSI-RS传输的总数量M。
如，
OffsetD＝OffsetC；
或，OffsetD＝Wx*OffsetC/W；
或，OffsetD＝W*OffsetC/M/Wx。
其中，OffsetC是在CSI-RS传输不拆分时，PDSCH RE相对于CSI-RS RE的功率偏移。
在本申请的一个实施例中，第一时刻是基于测量参考资源确定的。
测量参考资源具体可以为CSI参考资源。因为终端对信道或干扰的测量需要时间，所以在第一时刻对信道或干扰的测量所基于的第一下行参考信号需要是在测量参考资源之上或之前传输的，第一时刻基于测量参考资源确定，可以保证终端有充足的时间进行信道或干扰的测量。
