Description

一种参考信号的配置方法和装置 技术领域
本发明涉及通信领域，尤其涉及一种参考信号的配置方法和装置。
背景技术
在NR(new radio，新空口)通信系统中，CSI-RS资源集(CSI-RS resource set)包括一个或多个CSI-RS(channel state information-reference signal，信道状态信息CSI-RS)资源。每个CSI-RS资源对应的天线端口(Antenna Port，AP)的数量至多为32个。在CSI-RS资源用于波束的测量和上报的情况下，每个CSI-RS资源对应2个天线端口。时隙偏移(slot offset)表示基站发送CSI-RS触发指示的时隙和实际发送CSI-RS的时隙之间的偏移，在目前的方案中，基站可以非周期性的发送CSI-RS，此时CSI-RS的时隙偏移默认为0，即基站只能在发送CSI-RS触发指示的时隙内发送CSI-RS(当前时隙触发当前时隙发送)。
当前这种发送CSI-RS的方式会造成系统效率的低下。例如：在CSI-RS用于波束测量和上报的场景下，一个时隙内可用于发送承载模拟波束的CSI-RS所在的OFDM(orthogonal frequency division multiplexing，正交频分复用)符号数十分有限，当有较多的波束待扫描时，配置多个CSI-RS资源集在不同的时隙上发送各自的CSI-RS，此时便会涉及频繁的触发和频繁的上报，这样的配置方法一方面会浪费上行资源，另一方面也受限于终端设备的能力，使得系统效率低下。
发明内容
本发明实施例所要解决的技术问题在于，提供一种参考信号的配置方法和装置，在网络设备通过非周期方式发送参考信号的情况下，网络设备通过配置信息通知终端设备待发送的一个或多个参考信号资源集的时隙偏移，能实现网络设备根据在不同的时隙灵活的发送参考信号，减少触发参考信号和上报测量结果的数量，提高通信系统的效率。
第一方面，本申请提供了一种参考信号的配置方法，包括：网络设备确定配置信息，网络设备向终端设备发送配置信息，网络设备在配置信息所指示的时频资源上发送一个或多个参考信号资源集指示的参考信号。
其中，参考信号资源集包括至少一个参考信号资源，参考信号资源用于指示参考信号的配置，例如：参考信号资源包括一项或多项参数：天线端口号：时频资源位置、参考信号数量等。时隙偏移的单位为时隙，在NR中时隙的时间长度和子载波间隔有关。本实施例的时隙偏移可以是参考信号资源集对应的时隙和首个参考信号资源集对应的时隙之间的偏移，也可以是参考信号资源对应的时隙和前一个参考信号资源对应的时隙之间的偏移。
在本发明实施例中，网络设备通过发送配置信息向终端设备配置一个或多个参考信号资源集的时隙偏移，终端设备在接收到网络设备的配置信息以及触发指示后，根据配置信息能确定出一个或多个参考信号资源集对应的参考信号的时域位置，进而根据参考信号进行测量。本发明实施例提供的方案，可以使得网络设备实现灵活的发送参考信号的目的， 减少触发参考信号和上报测量结果的数量。
在一种可能的设计中，配置信息包括在高层信令中，高层信令中有1个单独的字段用来表示配置信息。高层信令表示物理层以上的信令，例如：高层信令包括：RRC信令或MAC-CE信令等。
在一种可能的设计中，配置信息包括在高层信令的“参考信号资源集配置”字段中，该字段还可以称为“参考信号资源集信息”或者其他名称，该配置信息用于指示一个参考信号资源信息的时隙偏移。
在一种可能的设计中，配置信息包括在高层信令的“参考信号资源设置配置”字段中，该字段还可以称为“参考信号资源设置信息”或者其他名称，该配置信息用于指示多个参考信号资源集的时隙偏移。
在一种可能的设计中，每个时隙偏移的最大值不大于终端设备上报的能力值。例如：终端设备上报的能力值包括最大子载波间隔、时隙偏移的最大值、比特位图的最大长度、最大调度带宽中的一种或多种。
在一种可能的设计中，配置信息包括比特位图，每个比特位对应1个时隙，当比特位的值为1时表示该比特位对应的时隙上发送参考信号资源集指示的参考信号，当比特位的值为0时表示该比特位置对应的时隙上不参考信号资源集指示的参考信号；或比特位的值为0时表示该比特位对应的时隙上发送参考信号资源集指示的参考信号，比特位的值为1时表示该比特位对应的时隙上不发送参考信号资源集指示的参考信号。
例如：比特位图的长度为4，比特位图为0010，比特位的值为1表示对应时隙上发送参考信号资源集指示的参考信号，比特位置的值为0表示对应的时隙上不发送参考信号资源集指示的参考信号。网络设备在时隙n上发送触发指示，那么比特位图0010的4个比特位置分别和时隙n、时隙n+1、时隙n+2、时隙n+3对应，根据比特位图中各比特位的值，网络设备只在时隙n+2上发送参考信号资源集指示的参考信号。
在一种可能的设计中，配置信息包括公共时隙偏移，公共时隙偏移表示多个参考信号资源集中相邻的两个参考信号资源集之间的时隙距离或者时隙间隔。其中，首个参考信号资源集对应方式触发指示的时隙，触发指示用于触发终端设备接收参考信号和/或上报测量结果。

本实施例的时隙偏移的单位为时隙(slot)，时隙偏移是相对于参考时隙的偏移，所述参考时隙可以是网络设备发送的触发指示所在的时隙，也可以是终端设备接收触发指示时所在的时隙，即时间偏移表示参考信号资源集对应的时隙和上述的参考时隙之间的偏移；所述触发指示用于触发终端设备接收参考信号和/上报测量结果。可选的，时隙偏移也可以 是参考信号资源集对应的时隙和前一个参考信号资源集对应的时隙之间的偏移。在本发明实施例中，网络设备以非周期方式发送参考信号，参考信号可以是CSI-RS，也可以是其他参考信号，本实施例不作限制。
其中，参考信号资源的时隙偏移具有一定的取值范围，时隙偏移的最大值可与终端设备上报的能力值有关。对于终端设备而言，从收到触发指示到实际接收参考信号并测量的最大时延可以是一种终端能力，具体可以体现为时隙偏移的最大值、非周期CSI-RS的时隙偏移最大值、时隙偏移比特位图的最大长度、非周期CSI-RS最大等待时延、非周期CSI-RS的时间窗等。在实施方式中，所述时隙偏移的最大值不大于终端设备上报的相关能力值。可选的，时隙偏移的最大值也可以为网络设备预配置或终端设备预存储的值，具体值不作限定。
所述配置信息通过高层信令发送给终端设备，所述高层信令为物理层以上的信令，例如：高层信号包括RRC(radio resource control，无线资源控制)信令或MAC-CE(media access control-control element，媒体访问控制-控制元素)信令等。如无特殊说明，以下以RRC信令为例。
在一种可能的实施方式中，该配置信息包括在高层信令的“参考信号资源集配置”字段中，该字段还可以称为参考信号资源集信息，或者其他名称。参考信号资源集配置用于指示参考信号资源集的配置，该配置包括但不限于参考信号资源的索引号、资源重复信息等。可选的，在本实施例中，该配置信息为数值。在本实施例中，每一个参考信号资源集中的所述配置信息独立配置，用于指示当前参考信号资源集的时隙偏移。
例如，参见图2b所示，参考信号为CSI-RS，配置信息用时隙偏移来表示，网络设备配置4个CSI-RS资源集，分别为CSI-RS资源集k、CSI-RS资源集k+1、CSI-RS资源集k+2、CSI-RS资源集k+3，那么网络设备为每个CSI-RS资源集配置1个时隙偏移，CSI-RS资源集k的时隙偏移为0，CSI-RS资源集k+1的时隙偏移为1、CSI-RS资源集k+2的时隙偏移为2，CSI-RS资源集k+3的时隙偏移为3，假设终端设备在时隙n上收到CSI-RS触发指示，根据高层信令收到的配置信令，终端设备获知当前时隙接收CSI-RS资源集k，n+1时隙接收CSI-RS资源集k+1，n+2时隙接收CSI-RS资源集k+2，n+3时隙接收CSI-RS资源集k+3。
在另一种可能的实施方式中，该配置信息包括在高层信令的参考信号资源设置配置字段中，该字段还可以称为参考信号资源设置信息，或者其他名称。参考信号资源设置配置用于表示多个参考信号资源集的配置，该配置包括但不限于时频资源信息。在当前配置方式下，所述配置信息的可以有如下四种实施方式：
实施例a，该配置信息包括比特位图bitmap，每个比特位对应1个时隙，首个比特位对应触发指示所在的时隙，当比特位置的值为1时表示该比特位对应的时隙上发送参考信号资源集指示的参考信号，当比特位的值为0时表示该比特位对应的时隙上不发送参考信号资源集指示的参考信号；或当比特位的值为0是表示该比特位对应的时隙上发送参考信号资源集指示的参考信号，当比特位置的值为1时表示该比特位对应的时隙上不发送参考信号资源集指示的参考信号。
具体的，比特位图中首个比特位和触发指示所在的时隙对应，比特位图对应连续的多 个比特位。可选的，配置信息还包括比特位图的长度，终端设备根据配置信息得到比特位图的长度，该比特位图的最大长度不大于终端上报的相关能力。
例如：参见图2c所示，参考信号为CSI-RS，比特位图的长度为4，网络设备配置的比特位图为1010，以比特位的值为1表示发送CSI-RS资源集指示的参考信号，以及比特位的值为0表示不发送CSI-RS资源集指示的参考信号为例。触发指示所在的时隙为时隙n，比特位图中的4个比特位分别和时隙n、时隙n+1、时隙n+2、时隙n+3对应，根据比特位图中各个比特位的值可以得出：时隙n上发送CSI-RS资源集k指示的CSI-RS，时隙n+1不发送CSI-RS资源集指示的CSI-RS，时隙n+2上发送CSI-RS资源集k+1指示的CSI-RS，时隙n+4上不发送CSI-RS资源集指示的CSI-RS。
实施例b：该配置信息包括公共时隙偏移，公共时隙偏移表示多个参考信号资源集中相邻的两个参考信号资源集之间的时隙偏移，首个参考信号资源集的时隙为触发指示所在的时隙。可选的，配置信息还包括参考信号资源集的数量，终端设备根据配置信息得知参考信号资源集的数量；或者所述参考信号资源集的数量等于当前参考信号资源设置中的所有已配置的参考信号资源集的数量；或者所述参考信号资源集的数量等于当前参考信号资源设置中的所有被触发的参考信号资源集的数量。
例如：参见图2d所示，参考信号为CSI-RS，公共时隙偏移为2，待配置的参考信号资源集的数量为3，触发指示所在的时隙为时隙n，根据公共时隙偏移为2，时隙n上发送CSI-RS资源集k指示的CSI-RS，时隙n+2上发送CSI-RS资源集k+1指示的CSI-RS，时隙n+4上发送CSI-RS资源集k+2指示的CSI-RS。
实施例c：该配置信息包括差分时隙偏移，差分时隙偏移表示多个参考信号资源集中相邻的两个参考信号资源集之间的时隙偏移，首个参考信号资源集的时隙和触发指示所在的时隙之间的时隙距离或时隙间隔等于差分时隙偏移。可选的，配置信息还包括参考信号资源集的数量，终端设备根据配置信息得知参考信号资源集的数量；或者所述参考信号资源集的数量等于当前参考信号资源设置中的所有已配置的参考信号资源集的数量；或者所述参考信号资源集的数量等于当前参考信号资源设置中的所有被触发的参考信号资源集的数量。
例如：参见图2e所示，参考信号为CSI-RS，差分时隙偏移为2，待配置的参考信号资源集的数量为3，触发指示所在的时隙为时隙n，根据公共时隙偏移为2，时隙n+2上发送CSI-RS资源集k指示的CSI-RS，时隙n+4上发送CSI-RS资源集k+1指示的CSI-RS。
实施例d：该配置信息包括逻辑判断信息(boolean)，在逻辑判断信息为真的情况下，网络设备根据预设的时间偏移发送一个或多个参考信号资源集指示的参考信号；或在逻辑判断信息为假的情况下，网络设备根据预设的时间偏移发送一个或多个参考信号资源集指示的参考信号。
具体的，时间偏移为预存储或预配置的值，本实施例的时间偏移可以是参考信号资源集对应的时隙和参考时隙之间的偏移，参考时隙为触发指示所在的时隙，也可以是参考信号资源集对应的时隙和前一个参考信号资源集对应的时隙之间的偏移。时间偏移的表示方式可参照实施例a中的比特位图的方式、实施例b中的公共偏移值、实施例c中的差分偏移值的方式或其他方式，本实施例不作限制。
在上述实施例a至d中，配置信息往往用于指示多个参考信号资源集的时隙位置，此时，网络设备和终端设备间需要约定所述多个参考信号资源集的实际发送顺序。一种可能的发送顺序为按照配置信息所指示的多个参考信号资源集的索引号的升序或降序方式依次发送。
例如：网络设备同时触发3个CSI-RS资源集，3个CSI-RS资源集的索引号分别为2、5、8，当CSI-RS资源集的索引号以升序方式发送CSI-RS时，CSI-RS的发送顺序为：CSI-RS资源集2指示的CSI-RS、CSI-RS资源集5指示的CSI-RS、CSI-RS资源集8指示的CSI-RS。当CSI-RS资源集的索引号以降序方式发送参考信号时，CSI-RS的发送顺序为：CSI-RS资源集8指示的CSI-RS、CSI-RS资源集5指示的CSI-RS、CSI-RS资源集2指示的CSI-RS。
在还一种可能的实施方式中，该配置信息配置在高层信令的一个单独的字段上。该配置信息可以为前述实施例a中的比特位图、实施例b中的公共时隙偏移、实施例c中的差分偏移值和实施例d中逻辑判断信息，区别为，在前述实施例中所述配置信息的作用范围仅限于某一个参考信号资源设置配置所关联的一个或多个参考信号资源集，而在本实施例中，所述配置信息的作用范围可以是多个参考信号资源设置配置所关联的多个参考信号资源集。
在另一种可能的实施方式中，网络设备向终端设备发送配置信息之后，还包括：网络设备向终端设备发送触发指示，触发指示用于触发指示终端设备接收参考信号和/或上报测量结果。
具体的，触发指示所在的时隙为首个参考信号资源集对应的时隙，触发指示可由DCI(downlink control information，下行控制信息)或MAC CE信令来发送，也由其他信令来发送，本实施例不作限制。其中，网络设备可以根据配置信息指示的时隙偏移在至少两个时隙上发送参考信号。需要说明的是，参考信号资源集在时隙中的时域位置可以由网络设备配置的，并通知给终端设备，或者网络设备和终端设备预存储或预配置有参考信号资源集在时隙中的时域位置，无需由网络设备进行通知。这样，网络设备一次能触发多个参考信号资源集指示的参考信号在至少两个不同时隙上的发送，无需频繁地为每个参考信号资源集发送触发指令，减少了触发次数，提高通信系统的交互效率和减少信令资源的消耗。同时，在非周期方式发送CSI-RS时，该出发指示还可以同时触发测量上报，因此，减少触发次数，也同时避免了频繁地、不必要的上报。
在一种可能的实施方式中，所述网络设备接收来自所述终端设备上报的测量结果；其中，所述测量结果由所述终端设备对所述一个或多个参考信号资源集指示的参考信号进行测量得到的。
其中，参考信号为CSI-RS的情况下，测量结果包括CSI(Channel Quality Indicator，信道质量指示)、RI(rank indication，秩指示)、PMI(Precoding Matrix Indicator，预编码矩阵指示)中的至少一种，当涉及波束测量和上报时，测量结果还可以包括CRI(CSI-RS resource indicator，CSI-RS资源指示)，L1-RSRP(Layer 1-Reference Signal Received Power，层1参考信号接收功率)等。
其中，终端设备对一个或多个参考信号资源集指示的参考信号进行测量，根据触发指示，一次将需要上报的测量结果上报给网络设备，避免分别对每个时隙上的参考信号进行 测量和上报，减少了终端设备测量和上报的次数，提高通信系统的交互效率。
S202、网络设备向终端设备发送配置信息，终端设备接收网络设备发送的配置信息。
其中，配置信息可包括在高层信令中，或包括在高层信令的参考信号资源集配置，或包括在高层信令的参考信号资源设置配置中，配置信息的表示方法可参照S201中的描述，此处不再赘述。
S203、网络设备在配置信息所指示的时频资源发送一个或多个参考信号资源集指示的参考信号，终端设备接收来自网络设备的参考信号。
具体的，终端设备根据配置信息的指示确定一个或多个参考信号资源集的时隙偏移。配置信息的指示一个或多个参考信号资源集的时间偏移的方法可参照S201的描述，此处不再赘述。终端设备接收来自网络设备的触发指示，根据触发指示所在的时隙和配置信息确定所述一个或多个参考信号资源集对应的参考信号发送的时隙，终端设备在确定的时隙上接收这些参考信号，进而根据参考信号进行测量。
这样，终端设备一次能接收多个在不同时隙上传输的参考信号资源集指示的参考信号，不需要每个参考信号资源集接收一次，减少了接收次数，提高通信系统的交互效率和减少信令资源的消耗。
在另一种可能的实施方式中，所述方法还包括：所述终端设备对所述网络设备发送的所述一个或多个参考信号资源集指示的参考信号进行测量得到测量结果；所述终端设备向所述网络设备发送所述测量结果。
具体的，在一些场景中，例如波束测量与上报，终端设备对一个参考信号资源集指示的参考信号进行测量，参考信号资源集包括至少一个参考信号资源，终端设备可以不上报参考信号资源集所有的参考信号资源的测量结果，只上报信号质量最好的前n个参考信号资源指示的参考信号的测量结果，n为大于1的整数。其中，信号质量包括但不限于RSSI(Received Signal Strength Indication，接收信号强度指示)、RSRQ(Reference Signal Receiving Quality，参考信号接收质量)和RSRP(Reference Signal Receiving Power，参考信号接收功率))中至少一种。
例如：CSI-RS资源集包括16个CSI-RS资源，分别为CSI-RS资源0至CSI-RS资源15，终端设备对16个CSI-RS资源各自指示的CSI-RS进行测量，终端设备确定信号质量最好的前4个CSI-RS资源，假设信号质量最好的前4个CSI-RS资源为：CSI-RS资源2、CSI-RS资源5、CSI-RS资源8和CSI-RS资源13，终端设备将上述信号质量最好的前4个CSI-RS资源的测量结果上报给网络设备。
根据上述实施例，终端设备对一个或多个参考信号资源集指示的参考信号进行一次测量，将测量结果上报给网络设备，避免分别对每个时隙上的参考信号进行测量和上报，减少了终端设备测量和上报的次数，提高通信系统的交互效率。
需要说明的是，一次上报多个CSI-RS资源集指示的CSI-RS的测量结果时，例如：涉及波束测量结果的上报，可以有如下的两种实施方式：
方式1：多个CSI-RS资源集所配置的CSI-RS资源之间的CSI-RS资源的索引号不重复，此时，上报的测量结果中包括CSI-RS资源的索引号，网络设备便可以获知与CSI-RS资源的索引号唯一对应的测量结果信息。
例如：待上报3个CSI-RS资源集的测量结果，3个CSI-RS资源集分别为CSI-RS资源集1、CSI-RS资源集2和CSI-RS资源集3，每个CSI-RS资源集包括8个CSI-RS，3个CSI-RS资源集的CSI-RS资源的索引号不重复，统一进行编号。假设CSI-RS资源集内的CSI-RS资源的索引号为0至7，CSI-RS资源集2内的CSI-RS资源的索引号为8至15，CSI-RS资源集3内的CSI-RS资源的索引号为16至23。终端设备向网络设备上报测量结果时，上报任一CSI-RS资源的索引号，在本次测量上报中均有唯一性。
方式2：多个CSI-RS资源集所配置的CSI-RS资源之间的全部或部分CSI-RS资源索引号重复，此时，上报的测量结果包括CSI-RS资源的索引号和该CSI-RS资源所在的CSI-RS资源集的辅助信息，该辅助信息包括但不限于CSI-RS资源集的索引号、CSI-RS资源集所对应的时隙索引号或CSI-RS资源集所对应的其他时间标识。
例如：待上报3个CSI-RS资源集的测量结果，3个CSI-RS资源集分别为CSI-RS资源集1、CSI-RS资源集2和CSI-RS资源集3，每个CSI-RS资源集包括8个CSI-RS，3个CSI-RS资源集的CSI-RS资源的索引号单独进行编号，各个CSI-RS资源集内的CSI-RS资源存在重复。假设CSI-RS资源集内的CSI-RS资源的索引号为0至7，CSI-RS资源集2内的CSI-RS资源的索引号为0至7，CSI-RS资源集3内的CSI-RS资源的索引号为0至7。终端设备向网络设备上报测量结果时，需要上报某一个CSI-RS资源集的索引号或其对应的时间标识，和该CSI-RS资源集中CSI-RS资源的索引号，才能确保在本次测量上报中，某一个CSI-RS资源的唯一性。
参见图3，为本发明实施例提供的一种参考信号的配置方法的另一流程示意图，在本发明实施例中，所述方法包括：
S301、网络设备确定配置信息。
具体的，配置信息用于指示一个或多个参考信号资源的时间偏移。
可选地，该配置信息包括在高层信令的参考信号资源配置字段中，该字段还可以称为参考信号资源信息字段或者其他名称。参考信号资源配置表示参考资源的配置，例如：该配置包括时频资源信息，本实施例的时间偏移表示参考信号资源的时域位置和触发后首个发送的参考信号资源的时域位置之间的偏移，也可以表示参考信号资源的时域位置和前一个参考信号资源的时域位置之间的偏移。参考信号可以是CSI-RS。
在一种可能的实施方式中，一个或多个参考信号资源对应同一个时隙，或一个或多个参考信号资源配置在同一个参考信号资源集中，此时，当属于同一个参考信号资源集时，所述一个或多个参考信号资源的时隙偏移相同。
具体的，时隙偏移以时隙为单位，一个或多个参考信号资源都对应同一个时隙，网络设备需要将一个或多个参考信号资源的时隙偏移配置为相同值。
在另一种可能的实施方式中，所述配置在同一个参考信号资源集中的一个或多个参考信号资源分为多个组，每个组的参考信号资源的时间偏移取同一值，不同组的参考信号资源的时间偏移互不相同。
例如：一个参考信号资源集包括共计m+n个参考信号资源，前m个参考信号资源的时间偏移值取第一值，后n个参考信号资源的时间偏移取第二值，前m个参考信号资源对应第一时隙，后n个参考信号资源对应第二时隙，m和n为大于等于1的整数。
又例如：时间偏移的单位为时隙，网络设备待配置16个CSI-RS资源，16个CSI-RS资源集属于同一个CSI-RS资源集，前8个CSI-RS资源对应时隙k，后8个CSI-RS资源对应时隙k+1，假设触发指示所在的时隙为时隙k，那么前8个CSI-RS资源的时间偏移均为0，后8个CSI-RS资源的时间偏移均为1。时间偏移的单位为OFDM符号的情况下，则前8个CSI-RS资源的公共符号偏移均为0，后8个CSI-RS资源的公共符号偏移均为14。
S302、网络设备向终端设备发送配置信息，终端设备接收来自网络设备的配置信息。
可选地，配置信息通过高层信令中的参考信号资源配置字段(该字段也可以是其他名称)发送给终端设备。
S303、网络设备根据配置信息所指示的时频资源发送一个或多个参考信号资源指示的参考信号，终端设备接收来自网络设备的参考信号。
具体的，终端设备接收网络设备发送的触发指示，确定触发指示所在时隙，以及根据配置信息确定一个或多个参考信号资源所在的时隙，终端设备在确定的时隙上接收来自网络设备的一个或多个参考信号资源指示的参考信号。
需要说明的是，在网络设备为参考信号资源集配置有第一时隙偏移，且为该参考信号资源集包括的至少一个参考信号资源配置有第二时隙偏移的情况下，若第一时隙偏移和第二时隙不相同，网络设备和终端设备确定时隙偏移包括4种方法：1、在配置第一时隙偏移的情况下，以第一时隙偏移为准；2、在配置第二时隙偏移的情况下，以第二时隙偏移为准；3、将第一时隙偏移和第二时隙偏移相加后作为最终的时隙偏移；4、两个时隙偏移均配置的情况下，选其中一个时隙偏移作为最终的时隙偏移。
根据图3的描述，在网络设备通过非周期方式发送参考信号，网络设备通过配置信息通知终端设备待发送的一个或多个参考信号资源的时间偏移，能实现网络设备根据在不同的时域位置灵活的发送参考信号。
