Description

信道状态信息参考信号CSI-RS的测量方法和装置 技术领域
本申请涉及通信技术，尤其涉及一种信道状态信息参考信号CSI-RS的测量方法和装置。
背景技术
新无线(New Radio，NR)中，为了进行无线资源管理(Radio Resource Management，RRM)测量，终端设备可以被配置为测量同步信号(synchronization signal，SS)块和/或信道状态信息参考信号(channel state information reference signal，CSI-RS)，基站基于终端设备上报的测量报告为终端设备完成移动性管理的决策(例如切换)，分配传输资源。
用于移动性测量的CSI-RS是通过测量目标(measurement object，MO)配置进行配置的。通过MO可以配置CSI-RS的时频资源位置，例如，周期、偏移值(offset)以及时隙内的符号位置。终端设备根据MO配置对网络设备发送的CSI-RS进行测量。
然而，由于终端设备在一段时间内可以接收和处理的CSI-RS资源数是受限于终端设备的存储和计算能力的，不同的终端设备实现可以有不同的规格(dimensioning)。不同的规格在不同的资源配置下有不同的测量性能，上述向终端设备配置CSI-RS的方式会存在资源浪费的问题。例如，有的终端设备可以接收和处理一个资源周期内的所有测量数据，但处理时间较长，在下一个资源周期到来之前无法完成处理，因此无法接收下一个资源周期资源的测量数据，从而造成资源浪费的问题。

示例性的，该第一消息可以是无线资源控制(Radio Resource Control，RRC)连接重配置消息。以周期性出现的4个CSI-RS资源为例，进行举例说明，该第一消息用于配置该周期性出现的4个CSI-RS资源，其周期可以是5ms，该周期性出现的4个CSI-RS资源的时域配置可以如图3所示，该图3的每一行对应一种时域配置。例如，参见图3的第一行所示，一个周期内的4个CSI-RS资源可以位于同一符号(symbol)上。再例如，参见图3的第二行所示，一个周期内的4个CSI-RS资源可以位于一个时隙(slot)内的两个符号上。又例如，参见图3的第三行所示，一个周期内的4个CSI-RS资源可以位于一个时隙(slot)内的四个符号上。还例如，参见图3的第四行所示，一个周期内的4个CSI-RS资源可以位于四个时隙(slot)内的四个符号上。
网络设备可以基于终端设备接收和处理CSI-RS资源的能力限制，确定该至少一个CSI-RS资源，并通过第一消息向终端设备配置该至少一个CSI-RS资源。例如，终端设备接收和处理CSI-RS资源的能力限制可以是终端设备主动上报给网络设备，或者，终端设备接收和处理CSI-RS资源的能力限制可以是预设的最低能力信息，该预设的最低能力信息可以是与终端设备的类型有关，例如，类型1对应一个预设的最低能力信息，类型2对应另 一个预设的最低能力信息。
步骤102、终端设备根据该第一消息对至少一个CSI-RS资源进行测量。
其中，该至少一个CSI-RS资源包括位于多个第一时间段内的CSI-RS资源，多个第一时间段满足以下至少一项：多个第一时间段中任意两个第一时间段之间的间隔大于第一阈值；或者，多个第一时间段中任意一个第一时间段内的CSI-RS资源的个数小于第二阈值。
换言之，该至少一个CSI-RS资源满足第一条件，该第一条件包括以下至少一项：该至少一个CSI-RS资源位于多个第一时间段内，该多个第一时间段中任意两个第一时间段之间的间隔大于第一阈值；或者，该至少一个CSI-RS资源位于多个第一时间段内，该多个第一时间段中任意一个第一时间段内的CSI-RS资源的个数小于第二阈值。
该第一时间段可以是第一时间窗口或第一时隙，该第一时间窗口可以包括多个时隙，第一时隙可以包括一个时隙。举例而言，该第一时间段可以是如图3所示的第一行中CSI-RS资源所在的时隙。需要说明的是，该第一时间段具体指终端设备需要测量CSI-RS资源的时间段，即终端设备可以对该时间段内的CSI-RS资源进行测量，而不测量该时间段之外的CSI-RS资源，该第一时间段也可以称之为测量时间段等，本申请实施例不以此作为限制，其也可以称之为其他名称。
换言之，终端设备根据该第一消息对多个第一时间段内的CSI-RS资源进行测量，并满足测量周期要求。
一种可实现方式，该多个第一时间段中任意两个第一时间段之间的间隔大于第一阈值，可选的，该多个第一时间段中任意两个第一时间段之间的间隔可以大于或等于第一阈值。换言之，该第一时间段为第一时间窗口时，该至少一个CSI-RS资源所在的多个第一时间窗口中，任意两个第一时间窗口之间的间隔大于第一阈值。该第一时间段为第一时隙时，该至少一个CSI-RS资源所在的多个第一时隙中，任意两个第一时隙之间的间隔大于第一阈值。一种示例，该第一阈值可以是预设的数值，该预设的数值用于反映终端设备的最低接收和处理CSI-RS资源能力，例如，任意两个第一时间段之间的最小间隔。举例而言，P表示第一阈值，P取任意正数，例如，2、4、40等。另一种示例，该第一阈值可以是网络设备基于终端设备上报的能力限制确定的。
另一种可实现方式，该多个第一时间段中任意一个第一时间段内的CSI-RS资源的个数小于第二阈值，可选的，该多个第一时间段中任意一个第一时间段内的CSI-RS资源的个数可以小于或等于第二阈值。换言之，该第一时间段为第一时间窗口时，该至少一个CSI-RS资源所在的多个第一时间窗口中，任意一个第一时间窗口内的CSI-RS资源的个数小于第二阈值。该第一时间段为第一时隙时，该至少一个CSI-RS资源所在的多个第一时隙中，任意一个第一时隙内的CSI-RS资源的个数小于第二阈值。一种示例，该第二阈值可以是预设的数值，该预设的数值用于反映终端设备的最低接收和处理CSI-RS资源能力，例如，任意一个第一时间段内的最大资源个数。举例而言，N表示第二阈值，N取任意整数，例如，4、5等。另一种示例，该第二阈值可以是网络设备基于终端设备上报的能力限制确定的。
又一种可实现方式，该多个第一时间段中任意两个第一时间段之间的间隔大于第一阈值，且任意一个第一时间段内的CSI-RS资源的个数小于第二阈值，可选的，该多个第一时间段中任意两个第一时间段之间的间隔可以大于或等于第一阈值，且任意一个第一时间段 内的CSI-RS资源的个数可以小于或等于第二阈值。该第一阈值和第二阈值的解释说明可以参见上述两种实现方式，此处不再赘述。
上述第一阈值和第二阈值是独立的阈值。可选的，第一阈值和第二阈值也可以是关联的。例如，{P＝P 1，N＝N 1}和{P＝P 2，N＝N 2}。其中，{P＝P 1，N＝N 1}表示该多个第一时间段中任意两个第一时间段之间的间隔大于P 1，且任意一个第一时间段内的CSI-RS资源的个数小于N 1。
本实施例，网络设备向终端设备发送第一消息，该第一消息用于配置至少一个CSI-RS资源，终端设备根据该第一消息对至少一个CSI-RS资源进行测量，该至少一个CSI-RS资源满足以下至少一项：该至少一个CSI-RS资源所在的多个第一时间段中，任意两个第一时间段之间的间隔大于第一阈值，或者，该至少一个CSI-RS资源所在的多个第一时间段中，任意一个第一时间段内的CSI-RS资源的个数小于第二阈值。网络设备可以基于终端设备接收和处理CSI-RS资源的能力限制，确定该至少一个CSI-RS资源，并通过第一消息向终端设备配置该至少一个CSI-RS资源，以避免向终端设备配置超出其能力限制的CSI-RS资源所造成的资源浪费，终端设备根据该第一消息对多个第一时间段内的CSI-RS资源进行测量，并满足测量周期要求。
针对现有技术中有的终端设备可以接收和处理一个资源周期内的所有CSI-RS资源，但处理时间较长，在网络设备配置的下一个资源周期到来之前无法完成处理，因此无法接收下一个资源周期资源的CSI-RS资源，从而造成资源浪费的问题，以及终端设备的测量周期无法确定的问题(即UE需要在网络配置的全部CSI-RS资源中选择部分资源进行测量，该选择与网络设备配置的CSI-RS资源的周期，不同资源之间的时域位置以及终端设备的实现策略有关)，本申请的网络设备可以基于终端设备接收和处理CSI-RS资源的能力限制，向终端设备配置该至少一个CSI-RS资源，以避免向终端设备配置超出其能力限制的CSI-RS资源所造成的资源浪费，终端设备可以测量网络设备配置的所有CSI-RS资源，终端设备可以明确测量周期，并且可以满足测量周期要求。
针对现有技术中有的终端设备只能接收和处理一个资源周期内的部分CSI-RS资源，但处理时间较短，终端设备可以接收下一个资源周期资源的部分CSI-RS资源，即终端设备只能接收每个资源周期内的部分CSI-RS资源，造成资源浪费的问题，本申请的网络设备可以基于终端设备接收和处理CSI-RS资源的能力限制，约束配置给终端设备的该至少一个CSI-RS资源，使得终端设备可以测量网络设备配置的所有CSI-RS资源，避免资源浪费，并且可以满足测量周期要求。
针对现有技术中有的终端设备只能接收和处理一个资源周期内的部分CSI-RS资源，但处理时间较短，终端设备可以接收下一个资源周期资源的部分CSI-RS资源，即终端设备只能接收每个资源周期内的部分CSI-RS资源，终端设备需要在网络设备配置的全部CSI-RS资源中选择部分资源进行测量，从而造成终端设备的测量周期无法确定的问题，本申请的网络设备可以基于终端设备接收和处理CSI-RS资源的能力限制，约束配置给终端设备的该至少一个CSI-RS资源，使得终端设备可以测量网络设备配置的所有CSI-RS资源，从而有明确的测量周期，并且可以满足测量周期要求。
在图2所示实施例的基础上，下面通过图4所示实施例，对终端设备主动上报自身接 收和处理CSI-RS资源的能力限制的CSI-RS的测量方法进行具体解释说明。本实施例以能力限制为第一信息和/或第二信息为例进行举例说明，本申请实施例的能力限制不以此作为限制，其还可以是其他信息，例如，第三信息等。
图4为本申请实施例的另一种CSI-RS的测量方法的流程图，本实施例的方法涉及终端设备和网络设备，如图4所示，本实施例的方法可以包括：
步骤201、终端设备向网络设备发送第一信息和/或第二信息。
网络设备接收终端设备发送的第一信息和/或第二信息。该第一信息用于指示第一阈值，该第二信息用于指示第二阈值。
一种可实现方式，终端设备向网络设备发送第一信息，该第一信息用于指示第一阈值。该第一信息可以是直接指示该第一阈值，终端设备通过该第一信息向网络设备上报其自身接收和处理CSI-RS资源的能力限制。例如，第一阈值的取值可以是4个数值中的任意一个，该4个数值可以是20、30、40和80，假设由于终端设备的能力限制，其需要任意两个第一时间段之间的间隔大于20，则该终端设备向网络设备发送的第一信息可以是两比特信息，如00，以向网络设备指示该第一阈值为20ms。
该第一阈值可以理解为终端设备可以支持的两次CSI-RS资源接收之间的最小间隔。
示例性的，如果终端设备仅测量周期性出现的第一时间窗口内的CSI-RS资源，则该第一信息表征终端设备可以支持的第一时间窗口的最小周期。

另一种可实现方式，终端设备向网络设备发送第二信息，该第二信息用于指示第二阈值。该第二信息可以是直接指示该第二阈值，终端设备通过该第二信息向网络设备上报其自身接收和处理CSI-RS资源的能力限制。例如，第二阈值的取值可以是4个数值中的任意一个，该4个数值可以是N 1、N 2、N 3和N 4，假设由于终端设备的能力限制，其需要任意一个第一时间段内的CSI-RS资源的个数小于N 2，则该终端设备向网络设备发送的第二信息可以是两比特信息，如01，以向网络设备指示该第二阈值为N 2。该第二信息可以是间接指示该第二阈值，例如，第二信息用于指示至少一个频域特性对应的最大资源个数，该频域特性包括子载波间隔(SCS)或带宽中至少一项，即第二信息用于指示终端设备在不同子载波间隔(SCS)和/或带宽所对应的最大资源个数。以终端设备上报不同子载波间隔(SCS)对应的最大资源个数为例，进行举例说明，例如，子载波间隔(SCS)为15kHz对应的最大资源个数为N 1，子载波间隔(SCS)为30kHz对应的最大资源个数为N 2，子载波间隔(SCS)为60kHz对应的最大资源个数为N 3，子载波间隔(SCS)为120kHz对应的最大资源个数为N 4，该第二信息用于指示不同子载波间隔(SCS)对应的最大资源个数。网络设备可以根据该第二信息确定第二阈值。
该第二阈值可以理解为终端设备每次CSI-RS测量接收可以支持的最大资源数。
示例性的，如果终端设备仅测量周期性出现的第一时间窗口内的CSI-RS资源，则该第二信息表征终端设备可以支持的第一时间窗口内的最大资源个数。
示例性的，如果终端设备测量任意时域位置上的CSI-RS资源，则该第二信息表征终端设备可以在一个时隙(上述第一时隙)内支持的最大资源个数。

该至少一个CSI-RS资源是终端设备进行CSI-RS测量的资源。该终端设备接收和处理CSI-RS资源的能力限制可以是预设的最低能力信息，该预设的最低能力信息可以是与终端设备的类型有关，例如，类型1对应一个预设的最低能力信息，类型2对应另一个预设的最低能力信息。
该预设的最低能力信息可以是预设的第一阈值和/或第二阈值。网络设备可以根据终端设备的类型确定第一阈值的取值，和/或，确定第二阈值的取值。
该至少一个CSI-RS资源所在的多个第一时间段可以满足以下至少一项，多个第一时间段中任意两个第一时间段之间的间隔大于第一阈值；或者述多个第一时间段中任意一个第一时间段内的CSI-RS资源的个数小于第二阈值。
该第一阈值可以与子载波间隔或带宽中至少一项相关，例如，不同的子载波间隔可以对应不同的第一阈值，15kHz对应最小间隔P 1，30kHz对应最小间隔P 2等。该第二阈值可以与子载波间隔或带宽中至少一项相关，例如，不同的CSI-RS资源带宽可以对应不同的第一阈值，带宽小于等于48个物理资源块(Physical Resource Block，PRB)对应最大资源个数N 1，带宽大于48个PRB对应最大资源个数N 2等。

需要说明的是，不同的子载波间隔(SCS)和/或带宽可以对应不同的第二阈值。第一阈值和第二阈值可以是独立的，也可以是关联的。
上述第一阈值和/或第二阈值可以是针对每一个MO(per MO)，即每个MO内终端设备可以支持的CSI-RS资源。上述第一阈值和/或第二阈值也可以是针对每一个终端设备，即任意两个MO内的CSI-RS资源所在的第一时间段之间的间隔需要满足上述第一阈值的限制，每次CSI-RS测量接收中所有MO的资源总数需要满足上述第二阈值的限制。

步骤303、终端设备根据该第一消息对至少一个CSI-RS资源进行测量。
网络设备基于预定义的终端设备的能力限制，向终端设备配置不超过其能力限制的CSI-RS资源，所以，本实施例的终端设备可以对网络设备配置的所有CSI-RS资源进行测量，并满足相应的测量周期要求。该测量周期可以是根据CSI-RS资源的周期以及第一时间窗口的周期确定的，也可以是根据CSI-RS资源的周期确定的。
如果网络设备配置的CSI-RS资源满足步骤301中的第一阈值和/或第二阈值限制，终端设备可以在每个第一时隙或第一时间窗口内测量所有的CSI-RS资源，并满足相应的测量周期的要求。或者，测量周期要求定义为M*max{P min，P CSI-RS}，M是滤波的样点数，P CSI-RS是CSI-RS资源的资源周期，P min是步骤301中第一时间窗口的最小周期。如果网络设备配置的周期小于P min，终端设备允许按照周期P min进行测量，跳过部分第一时间窗口。
本实施例，网络设备基于终端设备接收和处理CSI-RS资源的能力限制，确定至少一个CSI-RS资源，并且可以通过第一消息向终端设备配置该至少一个CSI-RS资源，从而实现网络设备可以根据终端设备的能力限制对不同的终端设备进行个性化的CSI-RS资源配置，当网络设备配置的CSI-RS资源不超出终端设备的能力限制时，终端设备可以测量网络设备配置的所有的CSI-RS资源，可以避免资源浪费，并且测量行为简单，避免了终端设备设计复杂的轮询算法对不同的周期的CSI-RS资源进行测量调度。终端设备的测量周期由网络设备配置的第一时间段的周期和/或网络设备配置的各个CSI-RS资源的周期确定， 网络设备对终端设备的测量周期有明确的预期，可以根据移动性管理的需求以及终端设备的能力限制配置CSI-RS资源。
