Description

信号传输方法和装置
本申请要求于2016年11月04日提交中国专利局、申请号为201610963254.2、申请名称为“信号传输方法和装置”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
本申请实施例涉及通信领域，并且更具体地，涉及一种信号传输方法和装置。
背景技术
在无线通信系统中，为了在保证传输可靠性的前提下提升传输效率，网络设备通常会估计用于传输信号的无线信道的质量，并根据无线信道的质量确定调度方案。在目前的无线通信系统中，通常会借助传输参考信号来获取无线信道的质量信息。通信系统通常使用不同种类的参考信号：一类参考信号用于信道质量测量或信道状态信息(channel state information，CSI)的测量，例如，小区特定参考信号(cell-specific reference signal，CRS)、信道状态信息参考信号(channel state information reference signal，CSI-RS)等；另一类参考信号用于波束管理，由于在波束赋形技术中，为跟踪赋形波束的变化，终端设备可以基于对不同赋形波束下的多个参考信号的信道质量测量选择得到最优的一个或多个赋形波束。
在现有技术中，用于波束管理的参考信号和用于CSI测量的参考信号是独立配置的，这样会导致参考信号所采用的资源不能灵活分配，资源利用率较低。
发明内容
有鉴于此，本申请实施例提供一种信号传输方法和装置，能够灵活分配不同种类的参考信号所采用的资源，从而提高资源的利用率。
第一方面，提供了一种信号传输方法，包括：网络设备确定参考信号资源池，所述参考信号资源池中的资源用于发送第一类参考信号和/或第二类参考信号；所述网络设备向终端设备发送指示信息，所述指示信息用于指示所述参考信号资源池中的资源；所述网络设备根据所述参考信号资源池，向所述终端设备发送第一配置信息和/或第二配置信息，所述第一配置信息用于指示所述参考信号资源池中发送所述第一类参考信号所采用的第一资源，所述第二配置信息用于指示所述参考信号资源池中发送所述第二类参考信号所采用的第二资源；所述网络设备根据所述第一配置信息向所述终端设备发送所述第一类参考信号，和/或所述网络设备根据所述第二配置信息向所述终端设备发送所述第二类参考信号。
具体地，网络设备可以配置一个既可用于波束管理又可用于信道质量信息获取的参考信号资源池，即该参考信号资源池中的资源既可用于第一类参考信号，又可用于第二类参 考信号，那么，该网络设备可以灵活配置该参考信号资源池中的资源用于波束管理和/或用于信道质量信息获取。例如，在不发送第二类参考信号的情况下，将该参考信号资源池中的资源完全给第一类参考信号使用；或者在不发送第一类参考信号的情况下，将该参考信号资源池中的资源完全给第二类参考信号使用；或者为该第一类参考信号和该第二类参考信号合理动态地分配该参考信号资源池中的资源，本申请实施例对此不作限定。
本申请实施例的信号传输方法，通过网络设备在发送第一类参考信号和/或第二类参考信号之前，确定参考信号资源池，并为第一类参考信号和/或第二类参考信号配置该参考信号资源池中的资源，从而能够灵活分配不同种类的参考信号所采用的资源，实现不同种类的参考信号资源间的共享，提高参考信号资源的利用率。
在第一方面的第一种可能的实现方式中，所述第一资源包括所述第二资源。
具体地，可以先选取用于发送第一类参考信号的M个资源，再从该M个资源中选择N个资源作为发送第二类参考信号所采用的资源，这样，第一类参考信号和第二类参考信号可以共享上述N个资源进行发送，从而实现资源间的共享，提高资源的利用率。
结合第一方面的上述可能的实现方式，在第一方面的第二种可能的实现方式中，所述第二资源为所述参考信号资源池中的资源除所述第一资源外的全部或部分剩余资源；或所述第一资源为所述参考信号资源池中的资源除所述第二资源外的全部或部分剩余资源。
具体地，若第一资源为该参考信号资源池中除第二资源外的全部剩余资源，或者第二资源为该参考信号资源池中除第一资源外的全部剩余资源，那么可以理解，用于第一类参考信号的资源与用于第二类参考信号的资源为互补的关系。在这种情况下，网络设备只需要向终端设备发送第一配置信息，该终端设备接收该第一配置信息，确定第一类参考信号采用的资源后，可以确定参考信号资源池中除第一类参考信号的资源外的剩余资源全部用于发送第二类参考信号，这样，无需该网络设备再向终端设备发送第二配置信息，节省了所需的配置信令开销。
第一资源还可以为该参考信号资源池中除第二资源外的部分剩余资源，或者第二资源为该参考信号资源池中除第一资源外的部分剩余资源。在这种情况下，网络设备若需要发送第一类参考信号和第二类参考信号，需要既发送第一配置信息，又发送第二配置信息。可选地，所述第一配置信息与所述第二配置信息可以由同一个物理层信令进行指示，也可以由不同的物理层信令分别进行指示，本申请实施例对此不作限定。

应理解，该高层信令可以为无线资源控制(radio resource control，RRC)信令，该物理层信令可以为下行控制信息(downlink control information，DCI)信令，该高层信令以及该物理层信令还可以为其他信令，本申请实施例对此不作限定。

(3)接收波束的更新，用于终端设备基于网络设备侧的多次重复相同的发射波束扫 描实现对接收波束的更新；
终端设备通过上述波束管理机制可实现对收发波束的追踪和更新。
在基于波束赋形的信号传输机制下，可以存在两类参考信号：一类参考信号用于信道质量测量或信道状态信息(channel state information，CSI)的测量，例如，小区特定参考信号(cell-specific reference signal，CRS)、信道状态信息参考信号(channel state information reference signal，CSI-RS)等；另一类参考信号用于波束管理，由于在波束赋形技术中，为跟踪赋形波束的变化，终端设备可以基于对不同赋形波束下的多个参考信号的信道质量测量选择最优的一个或多个赋形波束。
但是，现有技术中用于波束管理的参考信号和用于CSI测量的参考信号是独立配置的，其中，每一类参考信号的配置中包括参考信号的频域资源、时域资源、参考信号的端口数以及参考信号的密度等信息中的至少一个，这种参考信号的配置方法会导致两类参考信号所采用的资源不能灵活共享和分配，从而资源利用率较低。
考虑到用于波束跟踪的参考信号和用于CSI测量的参考信号间有一定的关联关系，例如，由于用于波束跟踪的参考信号和用于CSI测量的参考信号上作用的赋形波束通常相同，因此用于波束跟踪的参考信号可同时用于CSI测量，而用于CSI测量的参考信号也可用于波束跟踪，从而两类参考信号的配置间存在相关性和共享的可能性。基于此，本申请实施例提出了对两类参考信号灵活配置及共享的方法。
下文将用于波束跟踪的参考信号统称为第一类参考信号，将用于CSI测量的参考信号统称为第二类参考信号，但应理解，本申请实施例并不限于此，该第一类参考信号和第二类参考信号还可以是其他用途的参考信号，只要是对两种不同的参考信号的配置都可以适用本申请实施例的方法。第一类参考信号和第二类参考信号可对应相同的参考信号类型，也可对应不同的参考信号类型，本申请实施例对此不作限定。
图2示出了本申请实施例提供的信号传输方法200的示意性流程图。该方法200可以应用于图1所示的系统架构100，但本申请实施例不限于此。
S210，网络设备确定参考信号资源池，所述参考信号资源池中的资源用于发送第一类参考信号和/或第二类参考信号；
S220，所述网络设备向终端设备发送指示信息，所述指示信息用于指示所述参考信号资源池中的资源；对应地，所述终端设备接收所述指示信息；
S230，所述网络设备根据所述参考信号资源池，向所述终端设备发送第一配置信息和/或第二配置信息，所述第一配置信息用于指示所述参考信号资源池中发送所述第一类参考信号所采用的第一资源，所述第二配置信息用于指示所述参考信号资源池中发送所述第二类参考信号所采用的第二资源；对应地，所述终端设备接收所述第一配置信息和/或所述第二配置信息；
S240，所述网络设备根据所述第一配置信息向所述终端设备发送所述第一类参考信号，和/或所述网络设备根据所述第二配置信息向所述终端设备发送所述第二类参考信号；对应地，所述终端设备接收所述网络设备发送的所述第一类参考信号和/或所述第二类参考信号。
具体地，网络设备可以配置一个既可用于波束管理又可用于信道质量信息获取的参考信号资源池，即该参考信号资源池中的资源既可用于第一类参考信号，又可用于第二类参 考信号，那么，该网络设备可以灵活配置该参考信号资源池中的资源用于波束管理和/或用于信道质量信息获取。例如，在不发送第二类参考信号的情况下，将该参考信号资源池中的资源完全给第一类参考信号使用；或者在不发送第一类参考信号的情况下，将该参考信号资源池中的资源完全给第二类参考信号使用；或者为该第一类参考信号和该第二类参考信号合理动态地分配该参考信号资源池中的资源，本申请实施例对此不作限定。
本申请实施例的信号传输方法，通过网络设备在发送第一类参考信号和/或第二类参考信号之前，确定参考信号资源池，并为第一类参考信号和/或第二类参考信号配置该参考信号资源池中的资源，从而能够灵活分配不同种类的参考信号所采用的资源，实现不同种类的参考信号资源间的共享，提高参考信号资源的利用率。
应理解，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
应理解，本申请实施例中的第一类参考信号和第二类参考信号均为作用了波束赋形的参考信号，这两类参考信号可以为小区特定参考信号CRS，也可以为信道状态信息参考信号CSI-RS，还可以为其他任意一种用于信道质量信息测量的参考信号，本申请实施例对此不作限定。此外，应理解，本申请实施例并不排除第一类参考信号和第二类参考信号均为无波束赋形的参考信号。
还应理解，对于用于波束跟踪的参考信号来说，在模拟波束赋形和混合波束赋形的技术中，假设存在P份参考信号需进行时分发送以用于接收波束的更新训练，P为大于或等于1的整数，可选地，所述时分发送的多份参考信号可以占用一个子帧的多个符号。而所述多个符号可以为一个子帧内连续的多个符号，也可以为一个子帧内非连续的多个符号。由于用于波束跟踪的参考信号通常只需基于所述P份参考信号中的每份参考信号的信道质量测量得到每个发送或接收波束下的能量即可，因此用于波束管理的参考信号的时域资源位置可以为连续的多个符号，也可以为非连续的多个符号。且用于接收波束扫描和选择过程的至少一份参考信号中的每份参考信号通常对应了不同的接收波束，以便于终端设备基于对重复相同的至少一份参考信号的测量训练得到一个最优的接收波束。
而对于用于信道质量信息获取的参考信号来说，终端设备需基于对所述参考信号的测量需得到除波束索引(beam index，BI)或参考信号资源索引，如信道状态信息参考信号指示符(CSI-RS index，CRI)外的秩指示(rank indicator，RI)，预编码矩阵指示(precoding matrix indicator，PMI)以及信道质量指示(channel quality indication，CQI)等信道质量信息。因此，此类参考信号的时域符号位置及时域间隔需尽可能大，以用来跟踪同一子帧的不同时隙间的频偏和相位偏转跟踪。在一种优选地实现方式中，用于信道质量信息测量的参考信号的时域符号数应为至少两个，以实现较好的多符号联合信道估计。同时至少存在两个符号，其中一个符号位于一个子帧的前半个时隙，而另一个符号位于一个子帧的后半个时隙是此类参考信号的进一步设计目标。
具体而言，对于多级波束索引或参考信号资源索引的选择和上报：发送侧最优发射波束的选取和上报可以通过多级的方式来实现。具体地，发送侧的波束获取和选择可通过多级或多层的波束扫描方式来逐级完成。例如，第一级的波束扫描对应了第一波束宽度，第二级的波束扫描对应了第二波束宽度，依此类推，第Q级的波束扫描对应了第Q波束宽度，其中，Q为大于或等于1的整数。在每级的波束扫描中，接收侧基于信道质量的测量 结果选择出所属级别或波束宽度下对应的至少一个最优发射波束，并上报或通知所述最优发射波束的索引编号给发射侧。
这里，第一级波束扫描对应的最优波束的索引编号记为第一最优波束索引，第二级波束扫描对应的最优波束的索引编号记为第二最优波束索引，依此类推，第Q级的波束扫描对应的最优波束的索引编号记为第Q最优波束索引。所述第一最优波束索引的上报类型为第一上报类型，所述第二最优波束索引的上报类型为第二上报类型，依此类推，所述第Q最优波束索引的上报类型为第Q上报类型。
其中，所述第i上报类型可以不同于所述第j上报类型，i和j均为大于或等于1的整数，且i小于或等于j。具体地，所述第i上报类型不同于所述第j上报类型包括：
所述第i上报类型中所述第i最优波束索引独立编码，所述第j上报类型中所述第j最优波束索引与其他信道状态信息联合编码；或
所述第i上报类型中所述第i最优波束索引的编码比特数大于或等于所述第j上报类型中所述第j最优波束索引的编码比特数；或
所述第i上报类型中所述第i最优波束索引的编码码率小于或等于所述第j上报类型中所述第j最优波束索引的编码码率；或
所述第i上报类型中所述第i最优波束索引的编码方式(第一编码方式)与所述第j上报类型中所述第j最优波束索引的编码方式(第二编码方式)不同，其中，所述第一编码方式的可靠性大于等于所述第二编码方式。
上述分级的最优波束索引的不同编码方式可使得所述第i上报类型中所述第i最优波束索引的传输可靠性大于等于所述第j上报类型中所述第j最优波束索引的传输可靠性。由于第j上报类型中所述第j最优波束索引的选取依赖于所述第i上报类型中所述第i最优波束索引的选取，因此上述多级方式下的最优发射波束的选取和上报方式的性能可得到较好保证。
作为一个可选的实施例，所述第一资源包括所述第二资源。
具体地，可以先选取用于发送第一类参考信号的M个资源，再从该M个资源中选择N个资源作为发送第二类参考信号所采用的资源，这样，第一类参考信号和第二类参考信号可以共享上述N个资源进行发送，从而实现资源间的共享，提高资源的利用率。
作为一个可选的实施例，所述第二资源为所述参考信号资源池中的资源除所述第一资源外的全部或部分剩余资源；或所述第一资源为所述参考信号资源池中的资源除所述第二资源外的全部或部分剩余资源。
具体地，若第一资源为该参考信号资源池中除第二资源外的全部剩余资源，或者第二资源为该参考信号资源池中除第一资源外的全部剩余资源，那么可以理解，用于第一类参考信号的资源与用于第二类参考信号的资源为互补的关系。在这种情况下，网络设备只需要向终端设备发送第一配置信息，该终端设备接收该第一配置信息，确定第一类参考信号采用的资源后，可以确定参考信号资源池中除第一类参考信号的资源外的剩余资源全部用于发送第二类参考信号，这样，无需该网络设备再向终端设备发送第二配置信息，节省了所需的配置信令开销。
应理解，上述仅列举了网络设备配置第一类参考信号的情况，对于第二类参考信号的情况亦然，此处不再赘述。
第一资源还可以为该参考信号资源池中除第二资源外的部分剩余资源，或者第二资源为该参考信号资源池中除第一资源外的部分剩余资源。在这种情况下，网络设备若需要发送第一类参考信号和第二类参考信号，需要既发送第一配置信息，又发送第二配置信息。可选地，所述第一配置信息与所述第二配置信息可以由同一个物理层信令进行指示，也可以由不同的物理层信令分别进行指示，本申请实施例对此不作限定。
作为一个可选的实施例，所述指示信息包括下列信息中的至少一个：所述参考信号资源池中的资源的时域符号数、所述参考信号资源池中的资源的时域符号位置、所述参考信号资源池中的资源的频域资源位置以及所述参考信号资源池中的资源的端口信息。
作为一个可选的实施例，所述网络设备向终端设备发送指示信息，包括：所述网络设备通过高层信令和/或物理层信令向所述终端设备发送所述指示信息。
应理解，该高层信令可以为无线资源控制(radio resource control，RRC)信令，该物理层信令可以为下行控制信息(downlink control information，DCI)信令，该高层信令以及该物理层信令还可以为其他信令，本申请实施例对此不作限定。
作为一个可选的实施例，所述网络设备根据所述参考信号资源池，向所述终端设备发送第一配置信息和/或第二配置信息，包括：所述网络设备通过高层信令和/或物理层信令向所述终端设备发送所述第一配置信息和/或所述第二配置信息。
应理解，该高层信令可以为无线资源控制(radio resource control，RRC)信令，该物理层信令可以为下行控制信息(downlink control information，DCI)信令，该高层信令以及该物理层信令还可以为其他信令，本申请实施例对此不作限定。
作为一个可选的实施例，所述配置的第一类参考信号的符号信息与所述配置的第二类参考信号的符号信息组成所述配置的参考信号资源池的符号信息。
在一种具体实现中，高层信令配置的参考信号资源池中的资源为L个时域符号(L为大于或等于1的整数)，例如一个子帧中的L个符号。而在具体配置第一类参考信号和第二类参考信号的资源时，该网络设备可以具体指示该L个符号中的哪K个符号用于第一类参考信号(K为大于或等于1的整数)，而余下的L-K个符号则用于第二类参考信号。
应理解，若第二类参考信号用于信道质量信息获取，那么该第二类参考信号具有如下特殊需求，如其需满足：1)至少两个符号的传输；2)任意两个符号的间隔尽可能大。因此，上述第一类参考信号的资源与上述第二类参考信号的资源对参考信号资源池中的L个符号的分配关系可以为预定义的满足上述需求的有限几个预定义值，例如，当L＝10时，预定义的两类参考信号间的时域资源分配关系可以有：10+0，0+10，8+2，7+3，6+4，5+5等6种。此处可以将上述两类参考信号间的资源分配关系记为x+y的形式，其中，x,代表了用于第一类参考信号发送的时域符号数，而y代表了用于第二类参考信号发送的时域符号数。具体地，上述预定义的时域资源分配关系中10+0，0+10分别对应了只有第一类参考信号发送和只有第二类参考信号发送的两种特殊情况。8+2代表了用于第一类参考信号发送的时域符号数为8,而用于第二类参考信号发送的时域符号数为2。对于其他情况，例如7+3，6+4，5+5，与8+2类似，此处不再赘述。
此外，配置信令可以是L个比特的位图bitmap形式，其中L个比特中的每个比特具体用于指示对应的L个符号中的每个符号为用于第一类参考信号的符号还是用于第二类参考信号的符号，这样，在上述情况下，所需比特数可以小于或等于L。应理解，根据第 二类参考信号的特定设计需求，限定第二类参考信号的时域资源位置分布时，所需比特数则可以小于L，否则所需比特数等于L。
图3示出了本申请实施例提供的另一种信号传输方法300的示意性流程图。该方法300可以应用于图1所示的系统架构100，但本申请实施例不限于此。
S310，网络设备向终端设备发送第三配置信息，所述第三配置信息包括发送第一类参考信号和第二类参考信号所采用的端口的第一端口信息；对应地，该终端设备接收该第三配置信息；
S320，所述网络设备根据所述第三配置信息，确定第四配置信息，所述第四配置信息包括发送所述第二类参考信号所采用的剩余端口的第二端口信息；
S330，所述网络设备向所述终端设备发送所述第四配置信息；对应地，该终端设备接收该第四配置信息；
S340，所述网络设备根据所述第三配置信息，向所述终端设备发送所述第一类参考信号；对应地，该终端设备接收该第一类参考信号；
S350，所述网络设备根据所述第三配置信息和所述第四配置信息，向所述终端设备发送所述第二类参考信号；对应地，该终端设备接收该第二类参考信号。
本申请实施例的信号传输方法，通过网络设备为第一类参考信号和第二类参考信号配置共用的端口信息，再向该第二类参考信号配置剩余端口的端口信息，能够实现端口资源的共享，避免对相同端口信息进行重复配置，从而节省信令开销。
应理解，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
具体地，考虑到第二类参考信号，即用于信道质量信息获取的参考信号，需完成对信道质量信息的获取，从而有更多的空域自由度需求(即更多的空域天线端口数对应更多的空域自由度)，而第一类参考信号，即用于波束管理的参考信号，主要用于基于对波束能量的测量进行最优波束的选取。因此，第一类参考信号较第二类参考信号而言对空域自由度(即端口数)的需求不是很强烈。在本申请实施例中，第一类参考信号的端口数为第二类参考信号的端口数的子集，因此，网络设备可以先向终端设备发送第一类参考信号和第二类参考信号采用的端口信息的第三配置信息，该端口信息可以称为基本资源，该基本资源还可以包括参考信号的时域位置、频域位置、参考信号密度等等。网络设备在该基本资源的基础之上，为该第二类参考信号配置额外的端口信息，并将携带该额外的端口信息的第四配置消息发送给该终端设备。
在一种具体的实现中，当第一类参考信号资源的天线端口数为2，而第二类参考信号资源的天线端口数为4时，该网络设备只需为第二类参考信号配置新增的2个端口资源即可，从而既可提高第一类参考信号的资源和第二类参考信号的资源之间的灵活复用，又可节省网络设备的配置信令开销。
作为一个可选的实施例，所述第一端口信息和所述第二端口信息包括天线端口的个数和/或所述天线端口的时频域资源映射关系。
作为一个可选的实施例，发送所述第一类参考信号采用的第一天线端口的个数为M，发送所述第二类参考信号采用的第二天线端口的个数为N，所述M个第一天线端口的频域资源位置图样与所述N个第二天线端口中的M个第二天线端口的频域资源位置图样相 同，其中，所述M和所述N均为大于或等于1的整数，且所述M小于或等于所述N。
作为一个可选的实施例，所述第三配置信息包括所述M个第一天线端口的信息，所述第四配置信息包括所述N个第二天线端口中除所述M个第一天线端口外的N-M个第二天线端口的信息。
作为一个可选的实施例，所述M个第一天线端口根据所述N个第二天线端口虚拟加权运算得到。
具体地，用于发送第一类参考信号的M个端口与用于发送第二类参考信号的N个端口间存在嵌套关系。例如，第一类参考信号的M个端口可以由第二类参考信号的N个端口经过虚拟加权运算得到，其中，虚拟加权的方式可以是Walsh码或离散傅里叶变换(discrete fourier transform，DFT)矩阵的形式，例如，DFT矩阵为[1,1,1,1]，[1,1,-1,-1]，[1,-1,1,-1]和[-1,1,-1,1]。应理解，上述虚拟加权运算还可以通过其他方式，本申请实施例对此不作限定。
在一种具体的实现中，当第一类参考信号的天线端口数M＝2，第二类参考信号的天线端口数N＝4，而虚拟加权矩阵表示为[1,1,1,1]时，第二类参考信号的4个天线端口与第一类参考信号的2个天线端口间的关系满足y(p)＝y0，y(q)＝y1。这里，p＝0或1，q＝2或3，y0和y1是第一类参考信号的2个天线端口，y(0)，y(1)，y(2)，y(3)是第二类参考信号的4个天线端口。这里，前两个加权系数[1,1]代表了第二类参考信号的前两个天线端口与第一类参考信号的第一个天线端口间的虚拟加权系数，后两个加权系数[1,1]代表了第二类参考信号的后两个天线端口与第一类参考信号的第二个天线端口间的虚拟加权系数。
作为一个可选的实施例，所述方法还包括：所述网络设备向所述终端设备发送虚拟加权系数，所述虚拟加权系数用于进行所述虚拟加权运算。对应地，所述终端设备接收所述网络设备发送的所述虚拟加权系数。
作为一个可选的实施例，用于进行所述虚拟加权运算的虚拟加权系数为预定义的。
具体地，上述用于进行虚拟加权运算的虚拟加权系数可以是网络设备与终端设备协议约定的，也可以是该网络设备配置给该终端设备的，本申请实施例对此不作限定。
作为一个可选的实施例，所述第三配置信息和所述第四配置信息还包括下列信息中的至少一个：时域资源位置、频域资源位置以及所述第一类参考信号或所述第二类参考信号的密度。
具体地，所述第二参考信号的密度可以与系统参数绑定，即不同的系统参数对应不同的参考信号密度，这里不同的系统参数对应了不同的子载波间隔，例如，第一系统参数对应了15KHz的子载波间隔，第二系统参数对应了30KHz或60KHz的子载波间隔。
子载波间隔较小的系统参数对应的参考信号密度与两个系统参数对应的子载波间隔的比值有关。在一种具体的实现中，子载波间隔较小的系统参数对应的参考信号密度可以是两个系统参数对应的子载波间隔的比值的倒数，但本申请实施例对此不作限定。例如，当两个系统参数对应的子载波间隔的比值为2时，所述子载波间隔较小的系统参数对应的参考信号密度为1/2，即每隔一个资源单位放置一个参考信号。
当在至少两个符号上对应相同的参考信号时，可在重复的第二个符号上调制一些指示信息，所述指示信息可以用来指示下面信息中的至少一个：控制信道和业务信道的赋形波束是否相同，控制信道的传输方式指示，例如，发射分集、开环传输方式、闭环传输方式 等。可选地，所述控制信道的传输方式指示也可通过物理层控制信令，如DCI信息等进行指示，本申请实施例对此不做限定。
应理解，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
