Description

通信方法及装置
本申请要求于2017年11月24日提交中国专利局、申请号为201711192794.6、发明名称为“通信方法及装置”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
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
在新一代无线(new radio，NR)通信系统中使用波束进行传输，即通过在空间上朝向特定的方向发送信号，可以实现更高的天线阵列增益。因此，波束管理(beam management)是NR中的关键技术。在波束管理的过程中，网络设备在多个波束上向终端设备发送参考信号，终端设备在接收和测量后，向网络设备反馈测得的波束质量。
根据网络设备的配置，终端设备一次上报的波束质量最多为2个或4个。当上报的波束质量的数量大于1个时，采用差分方式上报波束质量，即将质量最好的波束质量直接上报并作为参考值，并上报其余波束质量与参考波束质量的差值，该差值表示为步长的整数倍。
参考波束的波束质量的取值范围是固定的，在上报比特数确定的前提下，量化步长也是一个固定的值。而差分波束的波束质量是相对参考波束的波束质量而言的，在不同的应用场景下，实际相对量化范围是不同的，在当前协议已经约定了差分波束的波束质量上报的比特数的情况下，如果采用一个固定的步长，很难适配各种场景，也无法获得更好的量化精度。
因此，网络设备如何配置更为合适的量化步长，终端设备如何选择合适的步长进行差分波束质量信息的上报，保证高精度地上报波束质量，是有待解决的问题。

图2为本申请实施例提供的一种通信方法的交互流程示意图，该方法可包括以下步骤：
S201、网络设备发送参考信号给终端设备。所述终端设备接收所述网络设备发送的参考信号。
S202、所述终端设备对所述参考信号进行测量，得到至少两个波束质量。
S203、所述终端设备发送参考波束质量信息和差分波束质量信息给所述网络设备；其中，差分波束质量的步长与载波频率和/或所述参考信号的类型对应。所述网络设备接收所述终端设备发送的参考波束质量信息和差分波束质量信息。
网络设备通过一个或多个发送波束发送参考信号给终端设备。终端设备通过一个或多个接收波束接收该参考信号。终端设备对接收到的参考信号进行测量，得到多个波束质量。然后，终端设备上报波束质量给网络设备。需要说明的是，在一种实现方式中，终端设备可以上报测量得到的所有波束质量给网络设备，例如，终端设备测量得到3个波束质量，则终端设备上报这3个波束质量给网络设备。在另一种实现方式中，终端设备可以上报测量得到的波束质量中大于门限值的波束质量给网络设备，例如，终端设备测量得到3个波束质量，其中，2个波束质量大于门限值，则终端设备上报这2个波束质量给网络设备。
波束质量可以以下任一种参数度量：参考信号接收功率(reference signal receiving power，RSRP)、参考信号接收质量(reference signal receiving quality，RSRQ)和信号与干扰加噪声比(signal to interference plus noise ratio，SINR)。下面如果不作说明，波束质量以RSRP为例进行描述。
根据网络设备的配置，终端设备一次上报的波束质量最多为2个或4个。当上报的波束质量的数量大于1个时，采用差分方式上报波束质量，即将质量最好的波束质量直接上报并作为参考值，并上报其余波束质量与参考波束质量的差值。具体地，如图3a所示的参考波束质量信息的状态示意图，RSRP的范围为-140dBm～-44dBm，采用7比特的参考波束质量信息进行上报，参考波束质量的步长为1dBm。如图3b所示的差分波束质量信息的状态示意图，采用4比特的差分波束质量信息进行上报，例如，假设需上报的波束质量包括3个值：-85dBm，-87dBm和-89dBm，则参考波束质量值为-85dBm，并假设差分波束质量的步长为2dBm，则终端设备需发送“0001”和“0010”给网络设备，网络设备解析“0001”，“0001”对应的与参考波束质量值的差值为-2dBm，则计算得到其波束质量为-85dBm-2 dBm＝-87dBm；同样地，计算得到“0010”对应的波束质量为-89dBm。本申请的方案用于确定差分波束质量信息的步长。
在一种场景下，例如，在网络设备配置为以直射径为主的情况下，低频率范围的波束数量较少，波束指向角的角度差较大，同一个终端设备所测量的多个波束之间的波束质量偏差范围较大；而高频率范围的波束数量较多，波束指向角的角度差较小，同一个终端设备所测量的多个波束之间的波束质量偏差范围较小。又例如，在网络设备配置为以反射径为主的情况下，则情况相反，低频范围的波束由于反射损耗较小，同一个终端设备所测量的各反射波束之间的波束质量偏差范围较小；而高频范围的波束由于反射损耗较大，终端设备测量所得的反射波束差异较大，其波束质量偏差范围较大。在上述场景中，如果终端设备采用一个固定的步长，无法保证需差分上报的波束质量都能被合理地差分量化。因而，在本申请的一个实现方式中，差分波束质量的步长与频率范围对应。具体地，每个频率范围对应至少一个步长，不同频率范围对应的步长不同。如图4a所示的步长与频率范围的关系示意图，在该示例中，被划分为N个频率范围，每个频率范围对应一个步长。终端设备在接收到网络设备通过多个波束发送的参考信号时，确定该多个波束所处的频率范围，从而确定与该频率范围对应的步长。
在另一种场景下，参考信号可以是同步信号块(SS/PBCH block)，也可以是信道状态信息参考信号(channel state information-reference signal，CSI-RS)，不同类型的参考信号上测得的波束质量可能不同。如果终端设备针对不同的参考信号采用一个固定的步长，无法保证需差分上报的波束质量都能被合理地差分量化。在本申请的另一个实现方式中，差分波束质量与参考信号的类型对应。具体地，每个参考信号的类型对应至少一个步长。如图4b所示的步长与参考信号的类型的关系示意图，在该示例中，CSI-RS和SS/PBCH block分别对应一个步长。终端设备在接收到网络设备通过多个波束发送的参考信号时，确定接收到的参考信号的类型，从而确定与该参考信号的类型对应的步长。
另外，发送SS/PBCH block时需要减少盲检的复杂度，因此，频率范围的划分相比CSI-RS对应的频率范围的划分应该更精细，即还需要结合参考信号的类型进行频率范围的划分。在本申请的又一个实现方式中，步长与频率范围和参考信号的类型对应。如图4c所示的根据SS/PBCH block配置的步长与载波频率的关系示意图，当参考信号的类型为SS/PBCH block时，其频率范围被划分为三个：小于3GHz、3GHz～6GHz和大于6GHz。每个频率范围对应至少一个步长。在该示例中，每个频率范围对应一个步长。如图4d所示的根据CSI-RS配置的步长与载波频率的关系示意图，当参考信号的类型为CSI-RS时，其频率范围被划分为两个：小于6GHz和大于6GHz。每个频率范围对应至少一个步长。在该示例中，每个频率范围对应一个步长。终端设备在接收到网络设备通过多个波束发送的参考信号时，确定接收到的参考信号的类型和该多个波束所处的频率范围，从而确定与该参考信号的类型和频率范围对应的步长。
终端设备在确定差分波束质量的步长后，根据该步长对需差分上报的波束质量进行量化，得到一个或多个差分波束质量信息。然后，发送参考波束质量信息和差分波束质量信息给网络设备。
根据本申请实施例提供的一种通信方法，采用的步长与载波频率和/或参考信号的类型 对应，使得需差分上报的波束质量能够被合理地量化，从而终端设备可实现准确地上报波束质量。
图5为本申请实施例提供的另一种通信方法的交互示意图，该方法可包括以下步骤：
S501、网络设备发送第一步长给终端设备。所述终端设备接收所述网络设备发送的第一步长。
S502、所述网络设备发送参考信号给所述终端设备。所述终端设备接收该参考信号。
S503、所述终端设备对所述参考信号进行测量，得到至少两个波束质量。
S504、所述终端设备根据所述第一步长或预存储的第二步长对需差分上报的波束质量进行量化。
S503、所述终端设备发送所述量化后的差分波束质量信息给所述网络设备。所述网络设备接收该差分波束质量信息，其中，所述差分波束质量信息为所述终端设备根据所述第一步长或预存储的第二步长对需差分上报的波束质量进行量化得到的。
预存储的第二步长有多种实现方式，例如协议约定的用于差分波束量化的步长，该步长可以在终端设备出厂时，预存储在终端设备中，，在没有接收到网络设备其他指示信息的情况下，终端设备默认采用该步长进行差分量化；再例如，终端设备接入该网络时，网络设备可以初始化分配一个用于差分波束量化的步长，终端设备将该步长存储下来，在没有接收到网络设备其他指示信息的情况下，终端设备默认采用该步长进行差分量化。但是，网络设备可以根据具体的发送场景，例如通信环境的变化(直射为主或反射折射为主)，测量参考信号的变化(同步信号块或CSI-RS)的情况下，配置一个新的差分波束质量的步长发送给终端设备。此时，终端设备可以根据实际测得的波束质量，在预存储的步长和网络设备后续发送的步长中选择一个合适的步长对需差分上报的波束质量进行量化。
在一个实现方式中，当接收到所述网络设备发送的所述第一步长时，S504具体为：根据所述第一步长对需差分上报的波束质量进行量化。具体如图6a所示，若网络设备没有额外发送步长，则终端设备采用预存储的步长作为差分量化的步长；若网络设备额外发送一个步长给终端设备，则终端设备选择网络设备发送的该步长作为差分量化的步长。这样，终端设备采用网络设备根据实际情况发送的步长，可对需差分上报的波束质量进行合理的量化。网络设备默认终端设备采用其发送的步长作为差分量化的步长，因而，网络设备可根据该步长、参考波束质量信息和差分波束质量信息，准确地得到终端设备上报的波束质量。
在另一个实现方式中，所述方法还包括：所述终端设备发送步长的选择信息给所述网络设备，所述选择信息用于表征对所述需差分上报的波束质量进行量化时，选择所述第一步长或选择所述第二步长。所述网络设备接收所述终端设备发送的步长的选择信息。虽然网络设备发送了一个新的步长，但是终端设备可以根据实际测量得到的波束质量情况自主选择差分波束质量的步长，从而，终端设备需要将步长的选择信息通知给网络设备，这样网络设备才能根据终端设备选择的步长、参考波束质量信息和差分波束质量信息，得到实际上报的波束质量。
具体地，所述步长的选择信息位于所述差分波束质量信息中。如图6b所示，若网络设备没有额外发送步长，则终端设备采用预存储的步长作为差分量化的步长，且4比特全部 作为差分波束质量信息进行上报；若网络设备额外发送一个步长给终端设备，则终端设备可选择预存储的步长或发送的新的步长作为差分量化的步长，且在4比特的差分波束质量信息中包括该步长的选择信息。例如，占用4比特差分波束质量信息的1比特用于包括该步长的选择信息。例如，用“0”表示采用预存储的步长，用“1”表示采用发送的新的步长；或者用“0”表示采用发送的新的步长，用“1”表示采用预存储的步长。其中，用于表征步长的选择信息的1比特可以是差分波束质量信息的高位或低位。
具体地，所述步长的选择信息位于其它上行控制信息(uplink control information，UCI)中。这里，其它上行控制信息是指除发送上述差分波束质量信息的上行控制信息之外的任一上行控制信息。如图6c所示，若网络设备没有额外发送步长，则终端设备采用预存储的步长作为差分量化的步长，且4比特全部作为差分波束质量信息进行上报；若网络设备额外发送一个步长给终端设备，则终端设备可选择预存储的步长或发送的新的步长作为差分量化的步长，且4比特全部作为差分波束质量信息进行上报，并采用额外的1比特表示步长的选择信息。
网络设备在接收到步长的选择信息后，可根据该选择信息所表征的步长、参考波束质量信息和差分波束质量信息，准确地得到终端设备上报的波束质量。
在以上实现方式中，网络设备发送的第一步长可以仅针对当前这次测量生效，也可以作为新的预存储步长被终端设备存储，并在之后的测量中，持续使用，直至再一次接收到新的第一步长。
根据本申请实施例提供的一种通信方法，通过配置两个差分波束质量的步长，终端设备选择其中一个步长对需差分上报的波束质量进行量化，使得需差分上报的波束质量能够被合理地量化，从而终端设备可实现准确地上报波束质量。
图7为本申请实施例提供的又一种通信方法的交互流程示意图，该方法可包括以下步骤：
S701、网络设备发送第一参考信号和第二参考信号给终端设备。所述终端设备接收所述网络设备发送的第一参考信号和第二参考信号。
S702、分别对所述第一参考信号和所述第二参考信号进行测量，得到第一波束质量和第二波束质量；
S703、发送第一差分波束质量信息和第二差分波束质量信息给所述网络设备，其中，所述第一差分波束质量信息为根据所述第一参考信号的步长对需差分上报的第一波束质量进行量化后得到的，所述第二差分波束质量信息为根据所述第一参考信号的步长对需差分上报的第二波束质量进行量化后得到的。
在本实施例中，网络设备通过多个波束分别发送两个参考信号，例如SS/PBCH block和CSI-RS。当然也可以发送其他的参考信号。终端设备在接收到两种参考信号后，分别对这两个参考信号进行测量，得到两个波束质量集，其中，一个波束质量集包括一个或多个第一波束质量，另一个波束质量集包括一个或多个第二波束质量。终端设备可分别根据步长对每个波束质量集中需差分上报的波束质量进行量化。其中，两个参考信号对应的差分波束质量的步长可以相同，也可以不同。终端设备可以分别发送每个波束质量集的参考波束质量信息和差分波束质量信息给网络设备。终端设备也可以以其中一个参考信号对应的 差分波束质量的步长为参考，对需差分上报的第一波束质量和第二波束质量进行量化，并将获得的第一差分波束质量信息和第二差分波束质量信息进行联合上报。网络设备在接收到第一差分波束质量信息和第二差分波束质量信息后，根据作为参考的步长、第一参考波束质量和第一差分波束质量信息，得到上报的第一参考信号对应的波束质量；以及根据作为参考的步长、第二参考波束质量和第二差分波束质量信息，得到上报的第二参考信号对应的波束质量。这样，网络设备可根据一个差分波束质量的步长，得到上报的两个参考信号对应的波束质量，实现简单。
本申请的一个实现方式中，所述方法还包括：相对于所述第一波束质量，所述终端设备根据功率偏移值对所述需差分上报的第二波束质量进行功率偏移；其中，所述第二差分波束质量信息为根据所述第一参考信号的步长对需差分上报的功率偏移后的第二波束质量进行量化后得到的。网络设备接收到第一差分波束质量信息和第二差分波束质量信息后，所述方法还包括：根据所述第一参考信号的步长和所述第二差分波束质量信息，得到第三波束质量；根据功率偏移值对所述第三波束质量进行功率补偿，得到所述第二波束质量。在该实现方式中，不同类型的参考信号上测得的波束质量可能不同，例如，如果采用第一参考信号的步长对第二参考信号对应的需差分上报的波束质量进行量化，可能无法保证需差分上报的波束质量都能被差分量化。因此，在进行量化前，可采用第二参考信号的发射功率相对于第一参考信号的发射功率的功率偏移值对需差分上报的第二波束质量进行功率偏移，然后再根据第一参考信号的步长对需差分上报的功率偏移后的第二波束质量进行量化。例如，测量接收到CSI-RS的波束质量，其中，需上报的波束质量包括：-85dBm，-87dBm和-89dBm；测量接收到SS/PBCH block的波束质量，其中，需上报的波束质量包括：-101dBm，-103dBm和-105dBm。采用CSI-RS对应的步长对-87dBm和-89dBm进行量化，步长为-2dBm，参考波束质量为-85dBm，则根据4比特的差分波束质量信息，能够量化的波束质量范围为-85dBm～-101dBm。而SS/PBCH block需差分上报的波束质量为-103dBm和-105dBm，已超出采用CSI-RS对应的步长进行量化的范围。因此，采用本实现方式的方法，先根据发射功率的偏移值对SS/PBCH block需差分上报的波束质量进行功率偏移。例如，网络设备和终端设备预先确定的SS/PBCH block与CSI-RS的发射功率的偏移值为-5dBm，则SS/PBCH block对应的功率偏移后的需上报的波束质量为：-96dBm、-98dBm和-100dBm。然后，终端设备根据CSI-RS对应的步长对SS/PBCH block对应的功率偏移后的需差分上报的波束质量进行量化。终端设备发送第一差分波束质量信息和第二差分波束质量信息给网络设备，网络设备解析获得第一差分波束质量信息和第二差分波束质量信息分别对应的第一波束质量和第二波束质量，然后网络设备对第二波束质量进行功率补偿。例如，根据上面的示例，网络设备解析获得第二波束质量为-96dBm、-98dBm和-100dBm，然后网络设备对每个第二波束质量进行功率补偿，即在每个第二波束质量基础上分别加上-5dBm，最终得到实际的第二波束质量为-101dBm，-103dBm和-105dBm。这样可以保证将SSB需差分上报的波束质量在联合上报中能够被量化。
本申请的另一个实现方式中，终端设备侧，所述方法还包括：终端设备根据第一参考波束质量值和所述第一参考信号的步长，对第二参考波束质量值进行差分量化，得到第三差分波束质量信息；以及所述终端设备发送所述第三差分波束质量信息给所述网络设备。 网络设备侧，所述方法还包括：所述网络设备接收所述终端设备发送的第三差分波束质量信息，所述第三差分波束质量信息为所述第二波束质量的参考值相对于所述第一波束质量的参考值的差分量化信息；以及所述网络设备根据所述第三差分波束质量信息和第一参考波束质量值，得到所述第二参考波束质量值。在该实现方式中，为进一步节省上报波束质量的开销，以第一参考波束质量作为参考，对第二参考波束质量进行差分，得到第三差分波束质量信息。进行差分的步长可以是第一差分波束质量对应的步长，也可以是另设的一个步长。例如，第一参考波束质量信息可以为7比特，第一、第二和第三差分波束质量可以均为4比特。终端设备可以同时发送第一、第二和第三差分波束质量信息，即第一、第二和第三差分波束质量位于一条信令中，也可以分别发送第一、第二和第三差分波束质量信息。网络设备在接收到第一、第二和第三差分波束质量后，根据第一差分波束质量对应的步长和第一、第二和第三差分波束质量，可以得到差分上报的第一差分波束质量、第二差分波束质量和第二参考波束质量。
根据本申请实施例提供的一种通信方法，终端设备在接收到网络设备发送的两个参考信号时，可根据其中一个参考信号对应的步长对两个差分波束质量进行量化，简化了波束质量的上报过程。
上述详细阐述了本申请实施例的方法，下面提供了本申请实施例的装置。

当需要发送数据时，处理器对待发送的数据进行基带处理后，输出基带信号至射频电路，射频电路将基带信号进行射频处理后将射频信号通过天线以电磁波的形式向外发送。当有数据发送到终端设备时，射频电路通过天线接收到射频信号，将射频信号转换为基带信号，并将基带信号输出至处理器，处理器将基带信号转换为数据并对该数据进行处理。为便于说明，图8中仅示出了一个存储器和处理器。在实际的终端设备产品中，可以存在一个或多个处理器和一个或多个存储器。存储器也可以称为存储介质或者存储设备等。存储器可以是独立于处理器设置，也可以是与处理器集成在一起，本申请实施例对此不做限制。
