Description

信道状态信息测量的配置方法及相关设备 技术领域
本发明实施例涉及通信技术领域，尤其涉及一种信道状态信息测量的配置方法及相关设备。
背景技术
在长期演进(英文：Long Term Evolution，LTE)版本8(英文：Release8，简称：R8)/R9中，为了对信道的质量进行测量，设计了公共参考信号(英文：Common Reference Signal，CRS)，用户设备(英文：User Equipment，UE)可以通过CRS进行信道的测量，从而决定UE进行小区重选和切换到目标小区。在LTE R10中为了进一步提高小区平均的频谱利用率和小区边缘频谱利用率以及各个UE的吞吐率，定义了信道状态信息(英文：Channel State Indication，CSI)参考信号(英文：CSI Reference Signal，CSI-RS)，CSI-RS用于信道的测量，通过对CSI-RS的测量可以计算出UE需要向基站(英文：evolved Node B，eNB)反馈的预编码矩阵索引(英文：Precoding Matrix Indicator，PMI)、信道质量信息指示(英文：Channel Quality Indicator，CQI)以及秩指示(英文：Rank Indication，RI)。
在3GPP无线接入系统中，eNB可以具有多个天线用于到UE的传输，从而允许eNB使用多输入多输出(英文：Multi-input Multi-output，MIMO)技术。MIMO是指在发送器和接收器二者处使用多个天线来提高通信性能，MIMO技术利用空间维度的资源，可以在不增加系统带宽的前提下，使信号在空间获得阵列增益、复用和分集增益以及干扰抵消增益，成倍地提升通信系统的容量和频谱效率，因而自其面世以来，一直得到人们的青睐。在第五代(英文：5th-Generation，5G)移动通信技术中，能够显著提高系统容量的MIMO技术仍然将作为一项关键技术，来满足新的无线接入技术(英文：New Radio Access Technology，New RAT)对高速率的传输需求。现有技术协同多点传输(英文：Coordinated Multipoint Transmission，CoMP)被认为是一种解决小区间干扰问题并提升边缘用户吞吐量的有效方法。CoMP技术中多个相邻小区可以联合处理或协调边缘用户来避免干扰并提升边缘用户吞吐量。此外，在5G中，不同的频段可以采用不同的帧结构。
UE在进行CSI-RS测量时会根据基站配置的参考信号图样(英文：pattern)接收参考信号，根据参考信号得到信道矩阵，进而获取信道状态信息并且上报给基站，比如根据该信道矩阵计算最优的PMI，以及在该PMI下计算CQI，最后将选择的PMI和CQI上报给基站。现有技术中的CSI测量只有一种帧结构，当CoMP系统中的不同小区采用不同的帧结构时，导致UE无法进行相邻小区的CSI测量，导致性能下降。但是在5G中，UE所在的服务小区的帧结构可能会与邻小区或者协作小区或者其他小区的帧结构信息不同。因此即使UE知道自己服务小区的帧结构，但是针对邻区的CSI测量，UE将无法进行。

具体实施方式
本发明实施方式部分使用的术语仅用于对本发明实施例的具体实施例进行解释，而非旨在限定本发明实施例。
图1是本发明实施例提供的一种应用场景的示意图。图1示出了高密集传输点(Transceiver Point，TRP)构成的超级小区(hypercell)。如图1所示，在高密集TRP传输场景中，一个用户设备可以与多个传输点通信，形成以用户设备为中心的通信系统(UE-cell-center-like)。通常，可以将位置上相邻的多个传输点划分成一个组，形成附图中虚线圆圈所示的一组传输点，可称为一个TRP组(TRP Set)，或者一个协作传输集合。需要说明的，TRP组的划分方式不限于依据位置的划分方式，还可以是其他划分方式，例如 将相关性强的TRP划分为一组，本发明实施例不做限制。
具体实现中，传输点可以是GSM系统或CDMA系统中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是未来5G网络中的基站、微型基站等网络设备，本发明实施例对此并不限定。
具体实现中，用户设备可支持CoMP传输方式，即用户设备可以与附图中的两个或多个传输点通信。用户设备可以称为接入终端、用户设备、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。具体实现中，用户设备可以是移动的或固定的，用户设备可以是蜂窝电话、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、可穿戴设备以及未来5G网络中的用户设备等。随着物联网(Internet of Things，IOT)技术的兴起，越来越多之前不具备通信功能的设备，例如但不限于，家用电器、交通工具、工具设备、服务设备和服务设施，开始通过配置无线通信单元来获得无线通信功能，从而可以接入无线通信网络，接受远程控制。此类设备因配置有无线通信单元而具备无线通信功能，因此也可以作为上述用户设备。
当用户设备在高速移动时，其所处环境经常发生变化，在高密集TRP场景下，用户设备可以从一个TRP切换到另一个TRP，也可以从一个TRP组切换至另一个TRP组。用户设备对应的用于信道测量的参考信号资源也需要相应变化。
现有技术中，针对CSI测量只有一种固定的帧结构，当不同小区采用不同的帧结构时，导致用户设备无法进行CSI测量，导致性能下降。
本发明实施例中，第一网络设备包括但不限于：传输点，第二网络设备包括但不限于：用户设备。
本发明实施例用于解决NR下不同的频段会采用不同的参数(numerology)和/或帧结构。其中，不同的numerology和/或帧结构决定了不同的子载波间隔，CP长度，帧结构时间长度，符号个数等等。进而导致不同的CSI-RS导频图样(pattern)。在这种情况下如果告知用户设备当前CSI-RS所在频段的numerology和/或帧结构，用户设备就可以获知当前频段对应的CSI-RS导频图样，或者CSI-RS所在的时/频域资源，进而可以在相应资源上接收CSI-RS信号，进而进行CSI测量。
为了解决NR下不同的频段会采用不同的帧结构，本发明实施例提供了一种信道状态信息测量的配置方法。本发明实施例中第一网络设备告知第二网络设备当前CSI-RS所在资源的参数信息，以使第二网络设备获知当前CSI-RS所在资源的帧结构，从而实现第二网络设备进行CSI测量，满足了第二网络设备在不同频段下的CSI-RS测量。
下面结合附图详细说明本发明实施例提供的信道状态信息测量的配置方法。
请参见图2，是本发明实施例提供的一种信道状态信息测量上报的配置方法的流程示意图，该方法包括但不限于以下步骤。
S201：第一网络设备向第二网络设备发送CSI参考信号所在资源的参数信息。
本发明实施例中，所述参数信息用于所述第二网络设备确定所述CSI参考信号所在资源的子载波间隔信息、循环前缀长度信息、帧结构时间长度信息和符号个数信息中的一种或多种。
本发明实施例中，参数信息具体为numerology信息和/或帧结构信息，可以表征出CSI-RS资源所在的导频图样或者CSI-RS所占的时域和/或频域资源。
具体的，所述参数信息用于所述第二网络设备确定所述CSI参考信号的导频图样，或者所述参数信息用于所述第二网络设备确定所述CSI参考信号所占的时域和/或频域资源。
作为一种可选的实现方式，当前的CSI参考信号所在资源的参数信息可以是第一网络设备直接通过信令的方式告知第二网络设备的。例如，所述第一网络设备通过无线资源控制(英文：Radio Resource Control，RRC)信令或者媒体接入控制(英文：Medium Access Control，MAC)信令为第二网络设备配置所述CSI参考信号所在资源的参数信息或者通过下行控制信息(英文：Downlink Control Information，DCI)信令向所述第二网络设备发送所述CSI参考信号所在资源的参数信息。这种情况下，所述参数信息为所述子载波间隔信息、所述循环前缀长度信息、所述帧结构时间长度信息和所述符号个数信息中的一种或多种。
作为另一种可选的实现方式，第一网络设备可以预先告知第二网络设备多组参数信息，之后，再通过信令的方式告知第二网络设备当前频段的CSI参考信号所在资源对应的参数信息。具体的，所述第一网络设备通过RRC信令或者MAC信令为第二网络设备配置参数信息指示信息或者通过DCI信令向所述第二网络设备发送参数信息指示信息，所述参数信息指示信息用于所述第二网络设备从多组参数信息中确定所述CSI参考信号所在资源的参数信息。这种情况下，第一网络设备可以预先定义不同比特信息与不同的参数信息的映射信息或者第一网络设备向第二网络设备发送不同比特信息与不同的参数信息的映射信息，之后，所述第一网络设备通过RRC信令或者MAC信令为第二网络设备配置当前频段对应的比特信息或者通过DCI信令向第二网络设备发送当前频段对应的比特信息，来告知第二网络设备当前的CSI-RS所对应的参数信息，这里，参数信息包括子载波间隔信息、所述循环前缀长度信息、所述帧结构时间长度信息和所述符号个数信息中的一种或多种。例如，第一网络设备将不同的参数用不同的比特信息表示，以下举例说明，不同的子载波间隔可以用2个bit表示或者其他个数的bit表示。例如，00代表子载波间隔为15kHz，01代表子载波间隔为30kHz，10代表子载波间隔为60kHz，依次类推，不同的bit值也可以代表其他不同的子载波间隔的情况。作为一种举例，可以参见表1所示。
表1
比特信息 子载波间隔
00 15kHz
01 30kHz
10 60kHz
11 Reserved
不同的循环前缀(英文：Cyclic Prefix，CP)长度信息可以用1个bit表示或者其他个数的bit表示。例如，0代表正常CP，1代表扩展CP。依次类推，不同的bit值也可以代表其他CP长度的情况。作为一种举例，可以参见表2所示。
表2
比特信息 CP长度
0 正常CP
1 扩展CP
不同的帧结构时间长度可以用2个bit表示或者其他个数的bit表示。例如，00代表子帧1ms，01代表时隙slot为0.5ms，10代表微时隙mini slot为0.25ms，依次类推，不同的bit值也可以代表其他不同的时间长度的情况。作为一种举例，可以参见表3所示。
表3
比特信息 帧结构时间长度
00 1ms
01 0.5ms
10 0.25ms
不同的符号个数可以用2个bit表示或者其他个数的bit表示。例如，00代表14个符号，01代表7个符号，10代表4个符号，11代表2个符号。依次类推，不同的bit值也可以代表其他不同的符号个数的情况。作为一种举例，可以参见表4所示。
表4
比特信息 符号个数
00 14
01 7
10 4
11 2
或者，还可以用几个比特信息来集中指示子载波间隔信息、循环前缀长度信息、帧结构时间长度信息和符号个数信息中的一种或多种。例如，用3个bit或者其他个数的比特表示，举例如下：000代表子载波间隔为15kHz，CP长度为正常CP，符号个数14个；001代表子载波间隔30kHz，CP长度为正常CP，符号个数7个；010代表子载波间隔60kHz，CP长度为正常CP，符号个数4个。依次类推，不同的bit值也可以代表其他不同的子载波间隔的值和/或其他不同的CP长度的值和/或其他不同的符号个数的值的情况。例如，可参见表5所示。
表5
比特信息 参数信息
000 子载波间隔15kHz；CP长度为正常CP；符号个数14个
001 子载波间隔30kHz；CP长度为正常CP；符号个数7个
010 子载波间隔60kHz；CP长度为正常CP；符号个数4个

110 子载波间隔30kHz；CP长度为正常CP；符号个数4个
111 子载波间隔60kHz；CP长度为正常CP；符号个数2个
此外，第一网络设备和第二网络设备之间也可以预定义多种不同的参数信息，然后在CSI-RS配置时，第一网络设备向第二网络设备发送参数信息指示信息来指示当前CSI-RS所在资源具体对应的是哪组参数信息。
其中表1至表5中的bit值以及参数信息，仅是举例说明，其他数值和/或者参数信息也适用，本发明实施例在此不做限定。
S202：所述第二网络设备根据所述参数信息确定所述CSI参考信号所在资源的子载波间隔信息、循环前缀长度信息、帧结构时间长度信息和符号个数信息中的一种或多种。
作为一种可选的实现方式，所述参数信息为所述子载波间隔信息、所述循环前缀长度信息、所述帧结构时间长度信息和所述符号个数信息中的一种或多种，则第二网络设备可以直接从所述第一网络设备获取到所述子载波间隔信息、所述循环前缀长度信息、所述帧结构时间长度信息和所述符号个数信息中的一种或多种。
作为另一种可选的实现方式，第一网络设备预先将不同的比特信息以及对应的参数信息(子载波间隔信息、循环前缀长度信息、帧结构时间长度信息和符号个数信息中的一种或多种)发送给第二网络设备，第二网络设备保存不同的比特信息与不同的参数信息之间的映射关系，之后，第一网络设备向第二网络设备发送当前传输的CSI-RS资源所在资源的参数信息对应的比特信息，第二网络设备根据该比特信息来查询映射关系，从而确定当前传输的CSI-RS资源所在资源的参数信息。例如，第一网络设备向第二网络设备发送一段比特位0010000，其中，该段比特位中第1位和第2位用于指示子载波间隔，第3位用于指示循环前缀长度，第4位和第5位用于指示帧结构时间长度，第6位和第7位用于指示符号个数。第二网络设备接收到该段比特位之后，查询上述表1至表4，确定出当前CSI-RS对应的参数信息分别为：子载波间隔15kHz、循环前缀为正常CP、帧结构时间长度1ms和符号个数14个。第二网络设备根据该组参数信息可以确定当前CSI-RS所在资源的导频图样或者当前CSI-RS所占的时域和/或频域资源，从而进行相应的CSI测量。
作为另一种可选的实现方式，所述参数信息还可以用几个比特信息来集中指示子载波间隔信息、循环前缀长度信息、帧结构时间长度信息和符号个数信息中的一种或多种。例如，针对表5，第一网络设备向第二网络设备发送一段比特位011，第二网络设备接收到该段比特位之后，查询上述表5，确定出当前CSI-RS对应的参数信息分别为：子载波间隔15kHz；CP长度为扩展CP；符号个数12个。第二网络设备根据该组参数信息可以确定当前CSI-RS所在资源的导频图样或者当前CSI-RS所占的时域和/或频域资源，从而进行相应的CSI测量。
以高层信令中的RRC信令为例，以现有的36.331中的信令指示为例，(当然也适用于其他的协议信令的情况，在此不做限制)举例如下：在CSI-RS配置信息中携带numerology信息(numerologyConfig)和/或帧结构信息(frameStructureConfig)。该numerology信息和/或该帧结构信息可以指示当前CSI-RS对应的参数信息。例如，numerologyConfig包括标识0至标识31，每个标识对应一组参数信息，第二网络设备根据该numerologyConfig即可确定当前CSI-RS对应的参数信息。或者，frameStructureConfig包括标识0至标识31，每个标识对应一组参数信息，第二网络设备根据该frameStructureConfig即可确定当前CSI-RS对应的参数信息。或者，在CSI-RS配置信息中携带参数信息指示信息，比如子载波间隔信息(SubcarrierSpacingConfig)和/或时间长度信息(timeUintConfig)和/或CP长度信息(CPConfig)和/或符号个数信息(symbolNumConfig)中的至少一项。例如，SubcarrierSpacingConfig可以为15kHz、30kHz、60kHz等等，第二网络设备根据该 SubcarrierSpacingConfig即可确定当前CSI-RS对应的子载波间隔。同样的，timeUintConfig可以为1ms、0.5ms、0.25ms等等，第二网络设备根据该SubcarrierSpacingConfig即可确定当前CSI-RS对应的帧结构时间长度。或者，timeUintConfig可以为subframe、slot、mini slot等等，对应的帧结构时间长度分别为1ms、0.5ms、0.25ms等等，因此，第二网络设备根据该SubcarrierSpacingConfig即可确定当前CSI-RS对应的帧结构时间长度。同样的，CPConfig可以为NZP、EZP等等，第二网络设备根据该CPConfig即可确定当前CSI-RS对应的CP长度信息。同样的，symbolNumConfig可以为14、12、7、6、4、3、2等等，第二网络设备根据该symbolNumConfig即可确定当前CSI-RS对应的符号个数。作为一种举例，RRC信令配置可参见如下表6所示。
表6

需要说明的是，上述子载波间隔信息(SubcarrierSpacingConfig)和/或时间长度信息(timeUintConfig)和/或CP长度信息(CPConfig)和符号个数信息(symbolNumConfig)的取值和命名只是作为一种举例，在实际应用中，这几个参数的命名和取值不作具体限定。
作为一种可选的实现方式，参数信息可以包括频域指示信息，所述频域指示信息用于指示所述参数信息适用的频域。第二网络设备接收到该参数信息后，即可以根据该频域指示信息确定当前频域上的CSI-RS的子载波间隔信息、循环前缀长度信息、帧结构时间长度信息和符号个数信息中的一种或多种。
作为另一种可选的实现方式，参数信息可以不包括频域指示信息，如果参数信息中没有频域指示信息，则配置参数信息时需要单独配置频域指示信息，即配置不同频域对应的参数信息。例如，第一网络设备配置频域指示信息(frequency Config List)用于指示频段的划分情况，而且针对划分的频段可以配置一个或者多个参数信息。如果没有频域指示信息，则默认频域为全带宽频段或者其他预定义的频段，具体的，在此不做限定。
具体如下所示：以物理层信令中的下行控制信息DCI为例，以现有的36.212中的信令指示为例，(当然也适用于其他的协议信令的情况，在此不做限制)，举例如下：通过DCI配置CSI-RS测量配置信息，在该CSI-RS配置信息中指示对应CSI-RS的参数信息以及该参数信息所适用的频域指示信息。具体如下：frequency Config List中包含了一个或多个frequency Config，Numerology Config List中包含了一个或多个Numerology Config(例如取值可以为0-31中的任意值)，Frame Structure Config List中包含了一个或多个Frame Structure Config(例如取值可以为0-31中的任意值)。Subcarrier Spacing Config List中包含了一个或多个Subcarrier Spacing Config(例如取值可以为15kHz、30kHz、60kHz等)。Time Uint Config List中包含了一个或多个Time Uint Config(例如取值可以为1ms、0.5ms、0.25ms等)。CPConfig List中包含了一个或多个CP Config(例如取值可以为NZP、EZP等)。Symbol Num Config List中包含了一个或多个Symbol Num Config(例如取值可以为14、12、7、6、4、3、2等)。
这里，每个frequency Config对应一个Numerology Config取值和/或一个Frame Structure Config取值。或者，每个frequency Config对应一个Subcarrier Spacing Config、一个Time Uint Config、一个CP Config和一个Symbol Num Config取值。其中，CSI configuration ID：用于指示CSI配置标识，包括测量集，RS集，上报集中的一个或者多个配置信息。频域指示信息(Frequency Config)：用于指示频域信息。Numerology Config：用于指示参数配置信息。帧结构配置信息(Frame Structure Config)：用于指示帧结构配置信息。Subcarrier Spacing Config：用于指示子载波间隔配置信息。Time Uint Config：用于指示帧结构时间长度配置信息。CP Config：用于指示CP长度配置信息。Symbol Num Config：用于指示符号个数配置信息。通过配置CSI测量配置信息对应的频域指示信息以及numerology信息和/或帧结构信息，第二网络设备可以确定某一频域范围内CSI-RS所在的资源位置，进而接收CSI-RS进行CSI测量。作为一种举例，具体的信令配置可以参见如下表7所示。
表7
Figure PCTCN2017118538-appb-000002
其中，频域指示信息(frequencyConfigList)用于指示频段的划分情况，而且针对划分的每一个频段都需要配置一个或者多个numerology信息和/或帧结构信息，或者说针对每一个频段都需要配置子载波间隔信息、循环前缀长度信息、帧结构时间长度信息和符号个数信息中的一种或多种。
需要说明的是，频域指示信息的划分方式、命名方式和取值范围本发明实施例不作具体限定。
通过本发明实施例，第一网络设备告知第二网络设备当前CSI-RS参考信号所在资源的参数信息，因此第二网络设备可以确定CSI-RS所在的资源位置，进而接收CSI-RS进行CSI测量。
进一步的，所述参数信息包括CSI参考信号标识信息，所述CSI参考信号标识信息用于指示所述CSI参考信号所在资源的子载波间隔信息、循环前缀长度信息、帧结构时间长度信息和符号个数信息中的一种或多种为所述第二网络设备当前的服务小区对应的子载波间隔信息、循环前缀长度信息、帧结构时间长度信息和符号个数信息中的一种或多种，或者所述CSI参考信号标识信息用于指示所述CSI参考信号所在资源的子载波间隔信息、循环前缀长度信息、帧结构时间长度信息和符号个数信息中的一种或多种为所述第二网络设备初始接入时获取的子载波间隔信息、循环前缀长度信息、帧结构时间长度信息和符号个数信息中的一种或多种。具体的，针对于服务小区的CSI-RS，第二网络设备可以通过初始接入确定自己所用的参数信息。但是配置CSI-RS的时候，第二网络设备不知道哪些是服务小区的CSI-RS配置，哪些是其他小区的CSI-RS配置。第一网络设备在发送CSI-RS配置信息时，可以增加CSI参考信号标识信息，用于表征CSI-RS配置的相关信息。比如增加是否为服务小区的CSI-RS配置的标识。通过该标识，第二网络设备可以确定当前的CSI参考信号是否为服务小区的CSI-RS，若是，则第二网络设备将服务小区的CSI-RS确定为当前CSI-RS所在资源的参数信息。或者，增加是否为接入的参数信息的配置的标识。通过该指示信息，第二网络设备可以确定该CSI-RS所在资源的参数信息是否与第二网络设备初始接入确定的信息或者是否与之前通过高层信令(比如RRC信令)配置或者物理层信令配置确定的信息一致。如果一致的话，第二网络设备将按照之前确定的numerology信息和/或帧结构信息接收CSI-RS进行CSI测量。
作为一种举例，CSI参考信号标识信息的信令配置可参见如下表8所示。在信令中携带了字段“IsservingCellConfig”，若该字段被配置为Ture，则第二网络设备可以获知当前CSI-RS所在资源的参数信息与第二网络设备当前服务小区对应的参数信息一致。

或者，作为一种举例，CSI参考信号标识信息的信令配置可参见如下表9所示。在信令中携带了字段“IsInitialConfig”，若该字段被配置为Ture，则第二网络设备可以获知当前CSI-RS所在资源的参数信息与第二网络设备初始接入确定的参数信息一致。
表9
Figure PCTCN2017118538-appb-000004
通过实施本发明实施例，第一网络设备通过指示是否与初始接入或者之前配置的信息确定的numerology信息和/或帧结构信息相同，如果相同则可以省掉第一网络设备向第二网络设备再通知的信令开销。
进一步的，所述参数信息包括小区标识信息，所述小区标识信息用于指示所述CSI参考信号所在资源的子载波间隔信息、循环前缀长度信息、帧结构时间长度信息和符号个数信息中的一种或多种为所述小区标识信息对应的子载波间隔信息、循环前缀长度信息、帧结构时间长度信息和符号个数信息中的一种或多种。具体的，第一网络设备预先通知第二网络设备一个或多个小区标识信息各自对应的参数信息，第二网络设备接收到该信息后，可以确定一个小区或者多个小区的numerology信号和/或帧结构信息。之后，在进行CSI-RS配置时，第一网络设备只需要向第二网络设备发送小区标识信息即可，第二网络设备根据该小区标识即可即可获知当前的CSI-RS所在资源对应的参数信息，根据该参数信息确定当前CSI-RS的导频图样或者时/频域资源，进而接收该CSI-RS，进行CSI测量。
例如，第一网络设备通过高层的公共信令(例如RRC信令或者MAC信令)，通知第二网络设备一个小区或者多个小区的numerology信号和/或帧结构信息。具体举例如下：第一网络设备通过高层的公共信令通知第二网络设备小区标识信息Cell_ID，以及该小区对应的载波的参数信息，具体的参数信息可以是numerology信息和/或帧结构信息，也可以是具体的子载波间隔信息、循环前缀长度信息、帧结构时间长度信息和符号个数信息中的一种或多种。之后，第一网络设备在向第二网络设备发送的CSI-RS配置信息中增加小区标识信息和/或载波配置标识，第二网络设备根据该小区标识信息和/或载波配置标识即可确定当前CSI-RS所在频段的参数信息。
其中，小区标识信息用于指示小区，而且针对划分的每一个小区标识都需要配置一个或者多个numerology信息和/或帧结构信息，或者说针对每一个小区都需要配置子载波间隔信息、循环前缀长度信息、帧结构时间长度信息和符号个数信息中的一种或多种。
需要说明的是，小区标识信息的命名方式和取值范围本发明实施例不作具体限定。
作为一种举例，小区标识信息对应的信令配置可参见如下表10所示。
表10
Figure PCTCN2017118538-appb-000005
或者，第一网络设备通过物理层信令通知第二网络设备一个小区或者多个小区的numerology信息和/或帧结构信息。具体的比如通过DCI指示：公共DCI通过小区公共临时标识加扰，比如小区1的信息用小区ID1加扰，小区2的信息用小区ID2加扰。通过告知第二网络设备需要接收的小区标识信息，进而接收该小区标识信息加扰的DCI。通过该信息第二网络设备可以获知一个小区或者多个小区的numerology信息和/或帧结构信息。第一网络设备在向第二网络设备发送的CSI-RS配置信息中增加小区标识信息，第二网络设备根据该小区标识信息确定该CSI-RS所在频段的参数信息。
或者，第一网络设备通过高层信令向第二网络设备通知一个或多个小区各自对应的numerology信号和/或帧结构信息，然后再通过DCI信令携带小区标识信息告知第二网络设备当前使用的numerology信息和/或帧结构信息。
通过本发明实施例，第一网络设备可以预先告知第二网络设备一个或多个小区的参数信息，然后在配置CSI-RS时添加小区标识信息，第二网络设备根据该小区标识信息即可确定当前CSI-RS所对应的参数信息，从而可以确定CSI-RS所在的资源位置，进而接收CSI-RS进行CSI测量。
