本申请要求在2022年02月28日提交中国专利局、申请号为202210184994.1、申请名称为“一种通信方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及一种通信方法和装置。
背景技术
在5G通信系统中，大规模多天线技术(Massive MIMO)对系统的频谱效率起到至关重要的作用。在采用MIMO技术时，为了保证终端设备与基站之间的良好通信性能，终端设备需要向基站反馈信道状态信息(channel state information，CSI)。
在时变信道的场景下，由于终端设备向基站反馈的CSI与真实信道不匹配。终端设备可以根据基站多次下发的信道状态信息参考信号(channel state information reference signaling，CSI-RS)估计得到该信道的多个时刻的信道信息，然后，终端设备根据该多个时刻的信道信息，得到多普勒信息，该多普勒信息可以通过该信道在角度时延域上的每个角度时延的多普勒频率表征，进一步，基于该多普勒信息可以预测后续时刻的信道，进而计算得到预测后续的CSI，最后，终端设备根据该预测的CSI，将预测信道的预编码矩阵指示(precoding matrix indicator，PMI)等信息上报给基站；或者终端设备将该信道的多个时刻的信道信息进行压缩发送CSI给基站，由基站根据该CSI，获得多普勒频率，进而预测该后续的信道。然而，通过基站集中下发多个时刻的CSI-RS来预测后续的信道，然而会增加传输CSI-RS的系统资源的开销。
因此，亟待需提出一种通信方法，在信道时变的场景中，不仅可以保证获取准确地信道状态信息，还可以降低系统资源的开销。
发明内容

第一通信装置作为参考信号的接收端，可根据参考信号资源集合中包括的N个(即至 少两个或多个)参考信号资源，从发送端接收对应的N个参考信号(即发送端发送N次参考信号)；然后，第一通信装置基于该N个参考信号进行信道测量，得到N个时刻的信道信息；其次，第一通信装置基于该N个时刻的信道信息，可获取用于确定信道的时变特征的多普勒信息，进而根据该多普勒信息，可准确的预测后续该信道的信道状态信息。并且每个参考信号资源的密度小于0.5，可使得参考信号占用资源块更加稀疏，从而降低传输参考信号所需的系统资源开销，节省出来的资源块可用于更多的参考信号的传输，提高了资源块的利用率。

具体实施方式
本申请实施例提供了一种通信方法和装置，其中，方法和装置是基于相同或相似技术构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
在5G通信系统中，大规模多天线技术(Massive MIMO)对系统的频谱效率起到至关重要的作用。在采用MIMO技术时，为了保证终端设备与基站之间的良好通信性能，终端设备需要向基站反馈信道状态信息(channel state information，CSI)。
为便于理解本申请实施例的技术方案，下面先对基站和终端设备之间传输信道状态信息CSI的基本流程进行简单介绍。
参考图1所示，基本流程如下：步骤一：基站向终端设备发送信道测量的配置信息，该配置信息用于配置信道测量，并用于向终端设备通知信道测量的时间及行为；步骤二：基站向终端设备发送信道状态信息参考信号(channel state information reference signaling，CSI-RS)，该CSI-RS用于信道测量；步骤三：终端设备根据该CSI-RS进行信道测量，得到最终的信道状态信息CSI；步骤四：终端设备将该CSI发送给基站，基站接收该CSI； 步骤五：基站根据该CSI进行数据的发送。例如，该CSI包括信道秩指示(rank indicator，RI)和信道状态指示(channel quality indicator，CQI)、预编码矩阵指示(precoding matrix indicator，PMI)等中的一项或多项，基站可以根据终端设备反馈的信道秩指示RI，确定该终端设备的传输数据的流数；基站还可以根据终端设备反馈的信道状态指示CQI，确定给终端设备传输数据的调制阶数，及信道编码的码率；此外，基站还可以根据终端设备反馈的预编码矩阵指示PMI，确定终端设备传输数据的预编码。
通常情况下，基站假设根据终端设备反馈的预编码矩阵指示PMI确定的预编码在CSI上报周期内是保持不变的。上述基站获取信道的CSI方案中，会存在CSI过期问题。CSI过期主要包括两个影响因素，可参考图2所示，具体包括以下：
(1)CSI生效时延t1：基站下发下行CSI-RS到终端设备反馈上行CSI之间的时延，以及基站算出预编码矩阵并使用的过程中存在的时延。
因此，导致CSI上报以后已经与真实的信道CSI存在延迟，当信道存在时变时，t1会导致CSI过期，引起性能下降。
(2)信道时变t2：基站在CSI反馈周期间持续使用最近上报的CSI计算出的预编码矩阵，即常数P0在t2时间段内是固定不变的。然而，当信道存在时变时，因基站获得的CSI过期，从而导致基站计算出的预编码矩阵与真实信道不匹配，进而导致传输性能下降。
因此，在信道时变的场景下，由于上述影响因素，导致终端设备向基站反馈的CSI与真实信道不匹配。目前的有效解决方案如图3所示，基站可以向终端设备连续且多次下发CSI-RS，终端设备根据该多次下发的CSI-RS估计得到该信道的多个时刻的信道信息，然后，终端设备根据该多个时刻的信道信息，得到多普勒信息，该多普勒信息可以通过该信道在角度时延域上的每个角度时延的多普勒频率表征，进一步，基于该多普勒信息可以预测后续时刻的信道，进而计算得到预测后续的CSI，最后，终端设备根据该预测的CSI，将预测信道的预编码矩阵指示PMI等信息上报给基站；或者终端设备将该信道的多个时刻的信道信息进行压缩发送CSI给基站，由基站根据该CSI，获得多普勒频率，进而预测该后续的信道。然而，通过基站集中下发多个时刻的CSI-RS来预测后续的信道，会增加传输CSI-RS的系统资源的开销。
因此，本申请中提供一种通信方法，该方法包括：第一通信装置获取第一配置信息，该第一配置信息用于指示一个或多个参考信号资源集合中的参考信号资源，该一个或多个参考信号资源集合中至少一个参考信号资源集合包括N个参考信号资源，N为大于或等于2的正整数；每个参考信号资源的密度为M，M为小于0.5的正数，该密度用于确定参考信号资源占用资源块的数量；然后，该第一通信装置根据该第一配置信息进行信道测量，得到信道状态信息；最后，该第一通信装置发送该信道状态信息。该方法通过降低密度的多个参考信号进行信道测量，以获得用于确定信道的时变特征的多普勒信息，不仅可获得准确地信道状态信息，也可降低传输参考信号所需的系统资源开销。
本申请的技术方案可以应用于第三代合作伙伴计划(3rd generation partnership project，3GPP)相关的蜂窝系统，例如，长期演进(long term evolution，LTE)系统等第四代(4th generation，4G)通信系统，新无线(new radio，NR)系统等第五代(5th generation，5G)通信系统，或者是第六代(6th generation，6G)通信系统等5G之后演进的通信系统，还可以应用于窄带物联网系统(narrow band-internet of things，NB-IoT)、卫星通信系统、无线保真(wireless fidelity，WiFi)系统，支持多种无线技术融合的通信系统。

S501：第二通信装置发送第一配置信息。
可选的，该第二通信装置为发送端，该第二通信装置为网络设备，例如基站。
相应的，第一通信装置获取该第一配置信息。
在本申请中，第一通信装置可以直接的从第二通信装置获取该第一配置信息，例如第一通信装置可以直接的从第二通信装置获取该第一配置信息，或者第一通信装置从第二通信装置获取第一信息，该第一信息中携带该第一配置信息。第一通信装置还可以间接的从第二通信装置获取该第一配置信息，例如由第三通信装置先从第二通信装置获取该第一配置信息，第一通信装置再从该第三通信装置获取该第一配置信息；或者由第三通信装置先从第二通信装置获取携带该第一配置信息的第一信息，第一通信装置再从该第三通信装置获取该第一信息携带的第一配置信息。因此，本申请对第一通信装置通过何种途径获取该第一配置信息不做具体限定。
可选的，该第一通信装置为接收端，该第一通信装置为终端设备。
在一种实施方式中，第二通信装置发送第一配置信息之前，还包括：第二通信装置确定第一配置信息。第二通信装置通过何种方式确定该第一配置信息，本申请不做限定。
示例性的，第二通信装置可以从已存储的多个配置信息中，确定该第一配置信息。或者该第一配置信息由第二通信装置根据实际需求实时进行配置并确定的。又或者该第一配置信息由其它装置确定，并发送给第二通信装置。
此外，为了与现有3GPP协议规范更好兼容，可在CSI报告配置信息中的码本配置(codebookConfig)信息中的码本类型(codebookType)字段的新增一个码本类型，该码本类型与现有3GPP协议规范中的码本类型不同，如可命名为typeII-Doppler、typeII-R18或typeII-Doppler-R18等，该新增的码本类型用以表示采用本申请实施例的技术方案来实现的信道信息反馈。应理解，上述码本类型的命名为示例性的，本申请实施例对新增的码本类型的命名不做具体限定。具体的，该第一配置信息用于指示一个或多个参考信号资源集合中的参考信号资源，该一个或多个参考信号资源集合中至少一个参考信号资源集合包括N个参考信号资源，N为大于或等于2的正整数；每个参考信号资源的密度为M，M为小于0.5的正数，该密度用于确定参考信号资源占用资源块的数量。
可选的，该参考信号可以为CSI-RS，该参考信号资源集合可以为非零功率(non-zero-power，NZP)-CSI-RS-resource set，该参考信号资源可以为NZP-CSI-RS-resource。

可选的，该M等于0.25或者该M等于0.125。
若参考信号资源的密度M等于0.25时，该参考信号资源占用资源块的数量等于4；若参考信号资源的密度为等于0.125时，该参考信号资源占用资源块的数量等于8。
本申请中每个参考信号资源的密度小于0.5，可以使得参考信号资源占用资源块更稀疏，从而降低传输参考信号所需的系统资源开销，节省出来的资源可用于更多的参考信号的传输，提高了资源块的利用率。
在一种实施方式中，该第一配置信息还用于指示第一偏移量，该第一偏移量用于指示该参考信号资源占用的起始资源块相对于参考资源块的偏移量。
其中，参考资源块(reference resource block，RB)为参考信号资源集配置的初始资源块。
可选的，该N个参考信号资源对应的第一偏移量均相同；或该N个参考信号资源对应的第一偏移量部分相同；或者该N个参考信号资源对应的第一偏移量均不相同。
在一种实施方式中，该N个参考信号资源均匀占用资源块。通过该实施方式，可以使得每个参考信号资源占用各资源块的次数尽量相等，从而可避免资源块使用不均而导致资源块利用率低。
在一种实施方式中，该第一配置信息还用于指示参考信号资源对应的周期和第二偏移量，该第二偏移量用于指示该参考信号资源占用的时隙相对于参考时隙的偏移量，该第二偏移量的取值范围为从0到参考信号资源对应的周期，该N个参考信号资源对应的周期均相同，且第一个该参考信号资源对应的第二偏移量至第N个该参考信号资源对应的第二偏移量为等间隔递增的。
其中，参考时隙可以被称为“参考点”，并且用作其他时隙的公共“参考点”，如该参考时隙在时域上从0开始编号，编号为0的时隙对于时域上的所有时隙是公共的。
示例性的，N个参考信号资源对应的周期均为t，t大于0，参考时隙为T0，该T0可为0，也可不为0。第一个参考信号资源对应的第二偏移量为a1，第二个参考信号资源对应的第二偏移量为a2，第三个参考信号资源对应的第二偏移量为a3……第N个参考信号资源对应的第二偏移量为aN；a1、a2、a3…aN取值范围为0至t，另外，a1、a2、a3…aN之间为等间隔递增的。
例如，该第一配置信息用于指示一个参考信号资源集合中10个参考信号资源时，每个参考信号资源对应的周期均为200slots，该10个参考信号资源对应的第二偏移量分别可以为{0、20、40、60、80、100、120、140、160、180}。
其中，每个参考信号资源对应的周期和第二偏移量可以通过对应的参考信号资源周期和偏移量CSI-ResourcePeriodicityAndOffset参数进行配置。
在一种实施方式中，第一配置信息还用于指示该参考信号资源对应的准共址QCL源，该N个参考信号资源对应的QCL源均相同；或者该第一配置信息还用于指示该参考信号资源对应的准共址QCL的类型，该N个参考信号资源对应的QCL的类型均相同。
示例性的，可以将N个参考信号资源对应的传输配置指示状态标识(transceiver configuration indicator-state identity，TCI-State Id)配置为相同。
在本申请实施例中，该第一配置信息可以直接的用于指示一个或多个参考信号资源集 合中的参考信号资源；或者该第一配置信息可以间接的用于指示一个或多个参考信号资源集合中的参考信号资源，例如该第一配置信息中包括第一信息，该第一信息用于指一个或多个参考信号资源集合中的参考信号资源。本申请对此不做限定。
S502：第一通信装置根据第一配置信息进行信道测量，得到信道状态信息。
在一种实施方式中，第一通信装置获取该第一配置信息之后，还包括：第二通信装置利用该第一配置信息指示的一个或多个参考信号资源集合中的参考信号资源，发送参考信号。相应的，第一通信装置根据第一配置信息可以获取由第二通信装置发送的参考信号，基于该参考信号测量并得到信道状态信息。
在一种实施方式中，该第一配置信息用于指示一个或多个参考信号资源集合中的参考信号资源，该一个或多个参考信号资源集合中至少一个参考信号资源集合包括N个参考信号资源，N为大于或等于2的正整数；第一通信装置根据第一配置信息进行信道测量，得到信道状态信息，包括：第一通信装置根据每个参考信号资源集合包括的N个参考信号资源进行信道测量，得到对应的一个信道状态信息。
示例性的，第二通信装置利用一个参考信号资源集合中包括的N个参考信号资源，连续向第一通信装置发送N次参考信号，其中，一个参考信号资源用于发送一次参考信号；第一通信装置接收该N次参考信号，并根据接收的该N次参考信号，进行计算得到测量结果(如N个时刻的信道信息)，进一步的，第一通信装置根据该测量结果获取多普勒信息，预测后续的信道并计算CSI，并在下述步骤S503中将该CSI发送给第二通信装置。或者，第一通信装置接收该N次参考信号，并根据接收的该N次参考信号，进行计算得到测量结果(如N个时刻的信道信息)并计算CSI，在下述步骤S503中将该CSI发送给第二通信装置，由第二通信装置根据该N个时刻的信道信息获取多普勒信息，进而预测后续的信道。
需要注意的是，上述具体的计算得到CSI的过程，以及根据N个时刻的信道信息获取多普勒信息均为现有技术，因此，可以参考现有的技术实现，此处不再具体描述。
S503：第一通信装置发送该信道状态信息。
相应的，第二通信装置接收该信道状态信息。本申请对第二通信装置通过何种途径获取该信道状态信息不做具体限定。
可选的，该第二通信装置为网络设备。
可选的，第二通信装置直接的从第一通信装置获取该信道状态信息；或者第二通信装置间接的从第一通信装置获取该信道状态信息，例如由第三通信装置从第一通信装置获取该信道状态信息，然后第二通信装置从该第三通信装置获取该信道状态信息。
综上所述，本申请中提供一种通信方法，该方法包括：第一通信装置获取第一配置信息，该第一配置信息用于指示一个或多个参考信号资源集合中的参考信号资源，该一个或多个参考信号资源集合中至少一个参考信号资源集合包括N个参考信号资源，N为大于或等于2的正整数；每个参考信号资源的密度为M，M为小于0.5的正数，该密度用于确定参考信号资源占用资源块的数量；然后，该第一通信装置根据该第一配置信息进行信道测量，得到信道状态信息；最后，该第一通信装置发送该信道状态信息。该方法通过降低密度的多个参考信号进行信道测量，以获得用于确定信道的时变特征的多普勒信息，不仅可获得准确地信道状态信息，也可降低传输参考信号所需的系统资源开销。
下面针对上述步骤S501中一个参考信号资源集合中的N个参考信号资源的密度如何 配置，通过以下两个具体实施例进行详细介绍。
在下述的两个实施例中，第一通信装置为终端设备，第二通信装置为网络设备，参考信号为CSI-RS，N个参考信号资源用于发送N次参考信号，即一个参考信号资源对应发送一次参考信号，参考信号资源的密度用于表示该参考信号资源配置占用资源块RB的数量。
实施例一
网络设备配置参考信号资源集合中的N个CSI-RS资源(用于发送N次CSI-RS)的密度均相同，且该N个CSI-RS资源的第一偏移量也均相同，该第一偏移量用于指示CSI-RS资源配置占用的起始资源块相对于参考资源块的偏移量。
具体的，当N个CSI-RS资源的密度均为0.25，且第一偏移量均为0(即CSI-RS资源集合中每个CSI-RS资源的起始RB位置相同，也就是每个CSI-RS资源的起始RB索引相同、且相对于参考资源块的偏移为0)，参考图6所示，该N个CSI-RS资源配置占用的资源块可分别为RB0、RB4、RB8......，即N次CSI-RS分别在RB0、RB4、RB8……上配置。需要说明的是，图6-图7中以一列阴影部分为一个CSI-RS资源为例进行描述，下文均如此，不再赘述。
终端设备侧获取第一配置信息后，可以确定每个资源集合中N个CSI-RS资源；当网络设备向终端设备发送N次CSI-RS时，终端设备可以从网络设备接收N次CSI-RS，然后根据该N次CSI-RS进行信道测量，得到N次信道测量结果(即N个时刻的信道状态信息)，其次，终端设备根据该N次信道测量结果，获得多普勒信息；进而终端设备根据该多普勒信息，预测该信道后续的信道状态信息，并上报给网络设备。或者终端设备根据该N次信道测量结果(即N个时刻的信道信息)不进行信道预测而是直接计算CSI上报给网络设备，由网络设备根据该N次信道测量结果的信道信息，获得多普勒信息，进而网络设备根据该多普勒信息，预测该信道后续的信道。
实施例二
为了增强终端滤波性能及角度时延估计精确性，网络设备配置参考信号资源集合中的N个CSI-RS资源(用于发送N次CSI-RS)的密度均相同，该N个CSI-RS资源的第一偏移量部分相同(即CSI-RS资源集合中部分CSI-RS资源的起始RB位置相同，也就是部分CSI-RS资源的起始RB索引相同、且相对于参考资源块的偏移量相同)，或者该N个CSI-RS资源的第一偏移量均不相同(即CSI-RS资源集合中的CSI-RS资源的起始RB位置均不相同，也就是CSI-RS资源的起始RB索引均不相同、且相对于参考资源块的偏移量均不相同)。
针对该N个CSI-RS资源如何占用资源块，具体可以包括以下几种情况：
第一种情况：当N小于密度的倒数值时，该N个CSI-RS所占用的资源块尽可能是均匀的分布于为终端设备调度的资源块中，即使得该N个CSI-RS资源配置尽可能在频域上均匀分布。
上述该N个CSI-RS所占用的资源块尽可能是均匀的分布在为终端设备调度的资源块中，可以理解为，在该N个CSI-RS占用的资源块满足对应的资源的密度的基础上，还需要求不同的CSI-RS尽量别总是重复的占用相同资源块，且不同的CSI-RS所占用的资源块的间隔相同。
因此，为了使得N个CSI-RS所占用的资源块尽可能是均匀的分布在为终端设备调度 的资源块中，可以令一个CSI-RS占用的资源块与下一个CSI-RS占用的资源块的间隔(或对应的第一偏移量的差值)等于资源的密度的倒数除以N，若得到的间隔不为整数，则向下取整，若取整后为0时，则令该间隔为1。
例如，当N＝2，2个CSI-RS资源的密度均为0.25时，即在第一个周期内，网络设备向终端设备发送2次CSI-RS(即对应2个CSI-RS)，第一个CSI-RS占用的资源块与第二个CSI-RS占用的资源块的间隔为2，即第一个CSI-RS资源配置可以在RB0、RB4、RB8…，第二个CSI-RS资源配置可以在RB2、RB6、RB10…；或者第一个CSI-RS资源配置可以在RB1、RB5、RB9…，第二个CSI RS资源配置可以在RB3、RB7、RB11等。
第二种情况：当N等于密度的倒数时，该N个CSI-RS资源对应的第一偏移量均不相同，即N个CSI-RS资源配置在频域上均不相同。
另外，针对该第二种情况，也需要求该N个CSI-RS所占用的资源块尽可能是均匀的分布在为终端设备调度的资源块中，即使得该N个CSI-RS资源配置尽可能在频域上均匀分布。
例如，当N＝4时，4个CSI-RS资源的密度均为0.25时，该N个CSI-RS资源的第一偏移量可以依次递增，如为了保证该4个CSI-RS所占用的资源块尽可能是均匀的分布在为终端设备调度的资源块中，可以参考上述第一种情况中计算间隔的方式，确定第一个CSI-RS占用的资源块与第二个CSI-RS占用的资源块的间隔为1，第三个CSI-RS占用的资源块与第二个CSI-RS占用的资源块的间隔为1，参考图7中(a)所示，在第一个周期内，网络设备向终端设备发送4次CSI-RS(即对应4个CSI-RS)，第一个CSI-RS资源配置可以在RB0、RB4、RB8…，第二个CSI-RS资源配置可以在RB1、RB5、RB9…，第三个CSI RS资源配置可以在RB2、RB6、RB10…，第四个CSI RS资源配置可以在RB3、RB7、RB11…。在第二个周期内，网络设备按照前述第一个周期内的发送方式向终端设备发送CSI-RS，以此类推，每个相同周期均按照前述第一个周期内的发送方式向终端设备发送CSI-RS。
或者参考图7中(b)所示，在第一个周期内，网络设备向终端设备发送4次CSI-RS(即对应4个CSI-RS)，该N个CSI-RS资源对应的第一偏移量之间没有必然联系，例如第一个CSI-RS资源配置可以在RB0、RB4、RB8…，第二个CSI-RS资源配置可以在RB3、RB7、RB11…，第三个CSI RS资源配置可以在RB2、RB6、RB10…，第四个CSI RS资源配置可以在RB1、RB5、RB9…。在第二个周期内，则网络设备按照前述第一个周期内的发送方式向终端设备发送CSI-RS，以此类推，每个相同周期均按照前述第一个周期内的发送方式向终端设备发送CSI-RS。
第三种情况：当N大于密度的倒数时，该N个CSI-RS资源配置所占用的资源块尽可能是均匀的分布在为终端设备调度的资源块中，即使得该N个CSI-RS资源配置尽可能在频域上均匀分布。
因此，针对该第三种情况，为了保证该N个CSI-RS资源配置所占用的资源块尽可能是均匀的分布在为终端设备调度的资源块中，在该N个CSI-RS占用的资源块满足对应的资源的密度的基础上，还需要求不同的CSI-RS所占用的资源块的间隔相同，且每个资源块被该N个CSI-RS所占用地总次数尽量相同。
例如，当N＝8，8个CSI-RS资源的密度均为0.25时，在第一个周期内，网络设备向终端设备发送8次CSI-RS(即对应8个CSI-RS)，为了保证该8个CSI-RS所占用的资源块尽可能是均匀的分布在为终端设备调度的资源块中，可以参考上述第一种情况中计算间隔的方式，确定第一个CSI-RS占用的资源块与第二个CSI-RS占用的资源块的间隔为1，第三个CSI-RS占用的资源块与第二个CSI-RS占用的资源块的间隔为1，第四个CSI-RS占用的资源块与第三个CSI-RS占用的资源块的间隔为1，即第一个CSI-RS资源配置可以在RB0、RB4、RB8…，第二个CSI-RS资源配置可以在RB1、RB5、RB9…，第三个CSI-RS资源配置可以在RB2、RB6、RB10…，第四个CSI-RS资源配置可以在RB3、RB7、RB11…，此时，若继续按照前述的方式确定第五个CSI-RS资源配置所占用的资源块时，因后面的资源块数量不够而无法实现时，可以使第五个CSI-RS至第八个CSI-RS分别重复占用对应的前述的第一个CSI-RS至第四个CSI-RS所占用的资源块，即每个资源块被占用的次数均为2，从而可以保证该8个CSI-RS所占用的资源块尽可能是均匀的分布在为终端设备调度的资源块中，即第五个CSI RS资源配置可以在RB0、RB4、RB8…，第六个CSI RS资源配置可以在RB1、RB5、RB9…，第七个CSI RS资源配置可以在RB2、RB6、RB10…，第八个CSI RS资源配置可以在RB3、RB7、RB11…。在第二个周期内，则网络设备按照前述第一个周期内的发送方式向终端设备发送CSI-RS，以此类推，每个相同周期均按照前述第一个周期内的发送方式向终端设备发送CSI-RS。
或者在一个周期内，网络设备向终端设备发送8次CSI-RS(即对应8个CSI-RS)，第一个CSI RS资源配置可以在RB0、RB4、RB8…，第二个CSI RS资源配置可以在RB3、RB7、RB11…，第三个CSI RS资源配置可以在RB2、RB6、RB10…，第四个CSI RS资源配置可以在RB1、RB5、RB9…，第五个CSI RS资源配置可以在RB0、RB4、RB8…，第六个CSI RS资源配置可以在RB3、RB7、RB11…，第七个CSI RS资源配置可以在RB2、RB6、RB10…，第八个CSI RS资源配置可以在RB1、RB5、RB9…。在第二个周期内，网络设备按照前述第一个周期内的发送方式向网络设备发送CSI-RS，以此类推，每个相同周期均按照前述第一个周期内的发送方式向网络设备发送CSI-RS。
可以理解的是，上述从第五个CSI-RS资源配置占用RB可以重复第一个CSI-RS资源配置占用的RB，第六个CSI-RS资源配置占用的RB可以重复第二个CSI-RS资源配置占用的RB，以此类推，此处不再具体描述。
通过以上配置，可以使得N个CSI-RS资源配置尽可能是均匀的分布在为终端设备调度的资源块中，从而可以获得更加精确的信道信息。
综上，本申请方法不仅在时变信道的场景中，可获得准确的信道状态信息，同时，通过上述具体实施例，将每个参考信号资源的密度设置为0.25或0.125，可以使得参考信号资源占用资源块更稀疏，因此，发送端(第二通信装置)密集多次下发参考信号的前提下，可以保证每次下发的参考信号能均匀的占用资源块，可以降低传输参考信号的开销，同时保证获得更加精确的信道信息。
