Description

一种干扰控制方法及装置 技术领域

在5G通信系统中允许在不同区域内部署不同的基站，使用不同的帧结构，服务不同业务。图1为目前几种可能的帧结构的示意图，如图1所示，帧结构1适用于下行大容量业务，帧结构2适用于上行大容量业务，帧结构3适用于URLLC业务。
进一步地，为了提高频谱资源利用效率，5G通信系统允许不同业务使用相同的频谱资源。但是由于帧结构不同，当不同业务使用的频谱资源发生重叠时，在重叠区域内会存在异向干扰。如图2所示，传输接收点(transmission reception point，TRP)1和用户设备(user equipment，UE)1支持上行大容量业务，使用帧结构2；TRP2和UE2支持URLLC业务，使用帧结构3。由于使用的帧结构不同，在重叠的时频资源上，UE1发送上行数据时会对UE2接收下行数据造成干扰，类似的，TRP2发送下行数据时也会对TRP1接收上行数据造成干扰。

请参考图4，为本申请实施例提供的一种干扰控制方法的流程示意图，该方法包括：
步骤S401、第一网络设备向第一终端设备发送第一指示信息，该第一指示信息用于指示第一参考信号(reference signal，RS)。可选的，该第一RS为在第一时频资源上进行信号传输的第二终端设备对应的RS。
相应的，第一终端设备可以接收来自第一网络设备的第一指示信息。
本申请实施例中，第一网络设备为第一终端设备的服务网络设备，或者也可以称为服务基站或服务节点。即，第一终端设备接入第一网络设备，由第一网络设备为其提供控制和数据服务。
所述第一时频资源是第一网络设备通过信令为第一终端设备分配的用于上行传输的时频资源，第一终端设备可以在该第一时频资源上向第一网络设备发送上行信息。所述上行信息可以包括上行数据信息、上行控制信息或探测参考信号(sounding reference signal，SRS)中的一种或多种。其中，上行数据信息可承载在物理上行共享信道(physical uplink shared channel，PUSCH)上，上行控制信息可承载在物理上行控制信道(physical uplink control channel，PUCCH)上。
在本申请的实施例中，信令可以是高层信令也可以是物理层信令，高层信令可以是RRC信令或媒体接入控制控制单元(medium access control-control element，MAC CE)，物理层信令可以是承载在物理下行控制信道(physical downlink control channel，PDCCH)上的下行控制信息(downlink control information，DCI)。
若将第一终端设备在第一时频资源上向第一网络设备发送上行信息的传输过程记为第一上行传输，则该第一上行传输可以是第一网络设备通过DCI动态调度或触发的上行传输，例如可以是动态调度的PUSCH、动态触发的PUCCH或非周期的SRS；该第一上行传输也可以是第一网络设备配置的上行传输，例如可以是配置授权的PUSCH、配置的周期性或半持续性的PUCCH或SRS等。
在第一网络设备向第一终端设备发送第一指示信息之前，第一网络设备可以与相邻的 第二网络设备进行信息交互，确定第一RS。具体的，第一网络设备可以获取第二网络设备的资源分配信息，根据该资源分配信息，确定第二网络设备调度的在第一时频资源上进行信号传输的第二终端设备，然后根据该第二终端设备的标识，将该第二终端设备对应的RS确定为第一RS。进而，第一网络设备可以通过第一指示信息向第一终端设备指示该第一RS。可选的，第一指示信息指示第一RS可以为，第一指示信息直接指示该第一RS的标识(identity，ID)。
应注意，本申请实施例中对第二终端设备的具体设备形态不作限定，第二终端设备可以认为是受第二网络设备管理的、由第二网络设备负责为其调度第一时频资源进行信号传输的终端设备或网络设备或其他类型的设备，如中继设备等，为了方便说明，本申请实施例中将这种终端设备或网络设备或其他类型的设备统称为第二终端设备。应理解，本申请实施例中的第二终端设备仅是对同在第一时频资源上进行信号传输的终端设备或网络设备或其他类型的设备的一种代称。
在第一网络设备向第一终端设备发送第一指示信息之前，第一网络设备可以与相邻的第二网络设备进行协调，确定每个不同邻近设备(包括第二终端设备)关联的RS信息，例如RS ID和时频资源信息。例如，第一网络设备与相邻的第二网络设备协调确定M个RS，每个RS对应一个邻近终端设备。也就是说，第二网络设备下的每个终端设备A会在预设的时频资源上发送自己关联的RS，如此，第一网络设备下的终端设备B可以测量得到所有终端设备A到终端设备B的干扰信道，便于终端设备B后续进行上行传输时进行干扰规避。
若第二终端设备具体是与第一终端设备同在第一时频资源上进行信号传输的终端设备，则该第二终端设备可以接入第二网络设备，并由第二网络设备为其提供控制和数据服务，如第二网络设备可以控制第二终端设备在第一时频资源上接收下行信息，所述下行信息可以包括下行数据信息、下行控制信息或信道状态信息参考信号(channel state information-reference signal，CSI-RS)中的一种或多种，其中，下行数据信息可承载在物理下行共享信道(physical downlink shared channel，PDSCH)上，下行控制信息可承载在PDCCH上。可以理解的是，在本申请的实施例中，PUSCH、PUCCH、PDSCH和PDCCH仅仅作为上行数据信道、上行控制信道、下行数据信道和下行控制信道的举例，在不同的通信系统中，这些信道可能有不同的名称，本申请实施例对此不做限定。
如此可知，由于第一终端设备与第二终端设备占据的时频资源相同，当第一终端设备在第一时频资源上发送上行信息时，可能会对第二终端设备从第二网络设备接收下行信息造成干扰。
所述第一指示信息可以是网络设备通过高层信令或物理层信令发送的。
在一种可能的实施方式中，如果第一上行传输是第一网络设备通过第一DCI动态调度或触发的上行传输，则第一指示信息可以包含在该第一DCI中发送给第一终端设备，即第一DCI在调度或触发第一上行传输的同时，还用于指示第一RS，如该第一DCI中可以包括第一RS的标识。
在另一种可能的实施方式中，如果第一上行传输是第一网络设备配置的上行传输，则第一指示信息可以包含在该第一上行传输的配置参数中发送给第一终端设备，即该第一上行传输的配置参数既用于配置该第一上行传输，还用于指示第一RS，如该第一上行传输的配置参数中可以包括第一RS的标识。
在又一种可能的实施方式中，第一指示信息也可以包含在单独的第二DCI或高层信令中发送给第一终端设备，第一终端设备可以根据预定义或网络指示的规则，确定第一指示信息应用的上行传输集合，第一上行传输为该上行传输集合中的一次上行传输。例如，第一指示信息包含在第二DCI中，该第二DCI中可以包括第一RS的标识，该第二DCI为单独发送的DCI，而非用于调度第一上行传输的DCI。假设第二DCI的发送时刻为T1，则该第二DCI应用的上行传输集合中可以包括起始时刻或结束时刻或整个时域位置在第一时间窗内的所有上行传输，第一时间窗根据发送时刻T1确定，该第一时间窗可以认为是第一RS适用的时域资源集合。又例如，第一指示信息包含在高层信令中，用于指示包含第一RS的第一RS集合以及第一RS集合内每个RS对应的时频资源集合，可选的，一个RS对应的时频资源集合可以是由一个时频资源A和该时频资源A在时域周期性平移后的所有时域资源组成。对应的，第一终端设备接收第一指示信息后，根据第一时频资源确定第一RS。
步骤S402、第一终端设备根据对第一RS的测量，得到第一RS对应的第一干扰信息。
如前所述，第一RS为在第一时频资源上进行信号传输的第二终端设备对应的RS。本申请实施例中，第二终端设备可以发送该第一RS，相应的，第一终端设备在接收到指示该第一RS的第一指示信息后，可以确定该第一RS所在的时频资源和/或该第一RS的发送序列，进而接收该第一RS。通过对该第一RS进行测量，第一终端设备可以得到第一RS对应的第一干扰信息。该第一干扰信息可以为第一RS对应的干扰信道的信息，该第一RS对应的干扰信道是指第一终端设备与第二终端设备之间的传输信道，或者更准确的说，是第二终端设备到第一终端设备的传输信道。
可选的，第一RS可以为非零功率参考信号(non zero power-reference signal，NZP-RS)或零功率参考信号(zero power-reference signal，ZP-RS)。若第一RS为NZP-RS，则第二终端设备可以在该RS对应的时频资源上发送该RS，由第一终端设备根据在该RS所在的时频资源接收到的信号和该RS的发送序列，进行信道估计，得到对应的干扰信道的信息。若第一RS为ZP-RS，则第二终端设备可以在该RS对应的时频资源上发送数据信号或参考信号，由第一终端设备根据在该RS所在的时频资源上接收到的信号，估计干扰信道，得到对应的干扰信道的信息，或者也可以由第一终端设备根据在该RS所在的时频资源上接收到的信号，计算干扰自相关矩阵，根据该干扰自相关矩阵计算干扰信道，得到对应的干扰信道的信息。例如，第一终端设备可以对该RS所在的时频资源上每个资源单元(resource element，RE)，计算接收信号向量与接收信号向量共轭转置的乘积，获取接收信号矩阵，再对邻近多个RE上的接收信号矩阵进行滤波平滑或者线性平均，获取对应的干扰自相关矩阵，最后对自相关矩阵进行奇异值分解，得到的奇异向量即为下面的干扰信道的特征方向，奇异值的根方即为下面的干扰信道的特征值。
可选的，第一RS可以为SRS或CSI-RS。
可选的，第一RS可以为周期性发送的RS。如此，第一终端设备可以根据对该第一RS的最近一次测量，得到第一RS对应的第一干扰信息；或者，第一终端设备也可以根据对该第一RS的所有测量，得到第一RS对应的第一干扰信息。
在一种可能的实施方式中，考虑到第一终端设备对第一RS进行测量到得出该次测量中第一RS对应的第一干扰信息之间需要一定的处理时间，第一终端设备可以根据在第一时间点之前对第一RS的最近一次测量，得到第一RS对应的第一干扰信息；或者，第一终 端设备也可以根据在第一时间点之前对该第一RS的所有测量，得到第一RS对应的第一干扰信息；或者，第一终端设备也可以根据在第一时间点之前对该第一RS的所有测量中的部分测量结果，得到第一RS对应的第一干扰信息。该第一时间点根据第一上行传输的时域位置确定，例如第一时间点可以是第一时频资源的时域起始位置往前倒推预设时长之后得到的时域位置，所述预设时长可以是预定义或网络配置给第一终端设备的，也可以由第一终端设备根据自身的处理能力自行设定，本申请并不限定。
步骤S403、第一终端设备根据第一干扰信息，确定第一传输参数。
步骤S404、第一终端设备根据第一传输参数，在第一时频资源上向第一网络设备发送上行信息。相应的，第一网络设备可以在第一时频资源上接收来自第一终端设备的上行信息。
本申请实施例中，第一传输参数可以包括如下的至少一种：空域配置参数、传输功率。其中，空域配置参数可以包括预编码矩阵和传输波束信息，预编码矩阵表示在进行第一上行传输时的空域处理行为，传输波束信息也可以称为模拟/数字波束信息或传输空域滤波设置，用于指示传输波束的方向或者发送天线阵列上不同天线阵子连接的移相器的相位取值等，传输功率是终端设备发送信号的输出功率或功率谱密度等参数。
在一种可能的实施方式中，第一传输参数可以为第一预编码矩阵，该第一预编码矩阵为第一终端设备在进行第一上行传输时应用的预编码矩阵，或者说第一终端设备对上行信息进行预编码时使用的预编码矩阵。如此，第一终端设备在确定出该第一预编码矩阵后，可使用该第一预编码矩阵在第一时频资源上发送上行信息。
具体的，第一预编码矩阵在第一子空间上的投影为0，该第一子空间为第一干扰信道矩阵最强的L个特征方向构成的子空间，L为正整数，该第一干扰信道矩阵由第一干扰信息确定，例如第一干扰信道矩阵可以是根据第一RS测量到的传输信道的矩阵或传输信道的转置矩阵。第一预编码矩阵在第一子空间上的投影为0也可以理解为，第一干扰信道矩阵最强的L个特征方向与第一预编码矩阵的乘积为零矩阵，或是第一干扰信道矩阵最强的L个特征方向与第一预编码矩阵的特征方向正交。
可选的，第一终端设备根据收发天线阵列和发送天线端口、接收天线端口的对应关系，确定第一干扰信道矩阵。例如，当第一终端设备存在4个收发天线、4个发送天线端口和4个接收天线端口，且4个收发天线与4个发送天线端口、4个接收天线端口一一对应时，第一终端设备根据第一RS测量得到接收干扰信道矩阵，该接收干扰信道矩阵或其转置矩阵即为第一干扰信道矩阵。又例如，当第一终端设备存在4个收发天线、2个发送天线端口和4个接收天线端口，且4个收发天线与4个接收天线端口一一对应，且第一天线和第三天线与2个发送天线端口一一对应时，第一终端设备根据第一RS测量得到接收干扰信道矩阵，该接收干扰信道矩阵或其转置矩阵的第一列和第三列组成的矩阵即为第一干扰信道矩阵。
所述L可以等于第一干扰信道矩阵的所有特征值中数值大于或等于第一阈值的特征值的数量，即第一终端设备测量到的第一干扰信道矩阵的所有特征方向中对应的特征值大于或等于第一阈值的特征方向的数量，第一阈值可以是预定义的或是预配置的或是第一网络设备向第一终端设备动态指示的，本申请并不限定。或者，所述L也可以等于1、2或S/2，其中，S为第一终端设备的收发天线的数量。再或者，所述L也可以等于S-R，其中，S为第一终端设备的收发天线的数量，R为第一终端设备发送上行信息时的数据层数，也是 第一预编码矩阵的列数，所述数据层数也可以称为数据流数或者解调参考信号(demodulation reference signal，DMRS)端口数，本申请并不限定。例如，如果第一上行传输为PUSCH传输(即上行信息为上行数据信息)，则R可以为该PUSCH传输的DMRS端口数；如果该第一上行传输为PUCCH传输(即上行信息为上行控制信息)，则R可以为该PUCCH传输的DMRS端口数；如果该第一上行传输为SRS传输，则R可以为该SRS传输的端口数目。再或者，所述L也可以是预定义或预配置或第一网络设备动态指示的，本申请并不限定。
示例性的，第一终端设备根据第一干扰信息，确定第一预编码矩阵可以包括如下的步骤S501至步骤S503：
步骤S501、第一终端设备确定第一子空间的零空间。
首先，第一终端设备根据第一干扰信息，确定第一干扰信道矩阵的最强的L个特征方向组成的子空间，即第一子空间。该第一子空间是S*1维复数向量所组成的向量空间的一个子空间，S为第一终端设备的收发天线的数量。该第一子空间中的任意一个向量可以表示为第一干扰信道矩阵的最强的L个特征向量的线性组合，或者说，第一干扰信道矩阵的最强的L个特征方向的线性组合都包含于该第一子空间中。
随后，第一终端设备可以将该第一子空间的正交空间，确定为第一子空间的零空间。该第一子空间的零空间是所述S*1维复数向量所组成的向量空间的另一个子空间，可以将其记为第二子空间。该第一子空间的零空间中的任意一个向量与第一子空间中的任意一个向量正交，或者说，与第一子空间中的所有向量正交的向量都包含于该第一子空间的零空间中。
步骤S502、第一终端设备确定第一上行传输的原始预编码矩阵。
原始预编码矩阵为第一终端设备在进行波束调整前，准备在第一上行传输中应用的预编码矩阵。该原始预编码矩阵由R个预编码向量组成，R为第一终端设备在发送上行信息时的数据层数。
具体的，在一种可能的实施方式中，如果第一上行传输为第一网络设备通过第一DCI调度的上行传输，则原始预编码矩阵可以是第一DCI动态指示的。例如，当第一上行传输是动态调度的PUSCH时，原始预编码矩阵可以根据第一DCI中的预编码矩阵指示(precoding matrix indicator，PMI)或SRS资源指示(sounding reference signal resource indicator，SRI)确定。如果第一上行传输为第一网络设备配置授权的上行传输，则原始预编码矩阵可以是第一上行传输对应的高层参数指示的。例如，当第一上行传输是配置授权的PUSCH时，原始预编码矩阵可以根据该配置授权的PUSCH的高层配置参数中的PMI或SRI确定。如果第一上行传输为第一网络设备配置的周期性的SRS或PUCCH，则原始预编码矩阵可以由该周期性的SRS或PUCCH的高层配置参数中关联的第二RS确定，该第二RS用于确定所述SRS或PUCCH的空域设置，即空域的发送预编码矩阵或者模拟波束等信息。
或者，在另一种可能的实施方式中，原始预编码矩阵也可以是第一终端设备自己确定的任意一个预编码矩阵，本申请并不限定。
步骤S503、第一终端设备将原始预编码矩阵在第一子空间上的投影，确定为第一预编码矩阵。
本申请实施例中，第一预编码矩阵也由R个预编码向量组成，但是组成第一预编码矩 阵的R个预编码向量为原始预编码矩阵中的R个预编码向量在第一子空间的零空间上的投影向量。即，第一预编码矩阵为原始预编码矩阵中的R个预编码向量在第一子空间的零空间上的投影向量组成的预编码矩阵。
具体的，以R＝1为例，针对原始预编码矩阵中的1个预编码向量，如果第一子空间的零空间中的某个单元向量与该预编码向量的内积为最大，则表示该单位向量为该预编码向量在第一子空间的零空间上的投影向量。
在一种可能的实施方式中，第一终端设备在确定出第一预编码矩阵后，可以先使用确定出的第一预编码矩阵，向第一网络设备发送SRS信号，该SRS信号与上述上行信息是不同的信息或信号。进而，第一网络设备可以接收该SRS信号，基于对该SRS信号的测量结果，调整调制与编码方案(modulation and coding scheme，MCS)，然后向第一终端设备发送第二指示信息，该第二指示信息用于指示调整后的MCS。相应的，第一终端设备在接收到该第二指示信息后，可以根据该第二指示信息指示的调整后的MCS发送上行信息。
如此，可使第一终端设备使用对原始预编码矩阵进行调整后的预编码矩阵发送上行信息时的信道质量与采用的MCS相匹配，从而有效提高第一网络设备接收上行信息的成功率。
可选的，第一终端设备可以同样使用确定的第一预编码矩阵，发送上行信息。或者，第一网络设备也可以在该第二指示信息中指示第一终端设备发送上行信息时具体使用的预编码矩阵，所述具体使用的预编码矩阵与第一终端设备发送SRS信号时使用的第一预编码矩阵可以相同或不同，并不限定。而且，第一网络设备可以在第二指示信息中直接指示该具体使用的预编码矩阵的信息，也可以通过第二指示信息中的SRI间接指示，即该具体使用的预编码矩阵为终端设备发送SRI指示的SRS时使用的预编码矩阵。
可选的，所述第一指示信息可以指示多个第一RS。在这种情况下，多个第一RS可以与第一时频资源包括的多个频域资源一一对应，其中，频域资源的单位可以是资源块(resource block，RB)、sub-RB或者子带subband，所述sub-RB是连续P个RE，其中P<12，所述subband是连续Q个RB，其中Q>＝2。以频域资源是子带subband为例，第一指示信息中可以指示多个RS的标识和每个RS对应的子带集合，或者第一指示信息中可以指示多个子带和每个子带关联的RS的标识。进一步地，第一终端设备可以针对每个RS，都在其对应的频域资源上测量一个对应的干扰信道，得到相应的干扰信息，然后针对每个干扰信道/干扰信息都执行如上述步骤S403和步骤S404中所述的类似处理，确定出在该RS对应的频域资源上的第一传输参数，进而使用该第一传输参数在该RS对应的频域资源上发送上行信息。
可选的，对于一个频域资源，第一指示信息也可以指示多个第一RS。在这种情况下，多个第一RS可以与多个第二终端设备对应。以频域资源为子带为例，此时，第一终端设备可以针对每个RS，都测量到一个对应的干扰信道，并对多个干扰信道进行聚合得到最终的干扰信道，即相应的干扰信息。最后，针对聚合后的干扰信道/干扰信息执行如上述步骤S403和步骤S404中所述的类似处理，确定出在该子带上的第一传输参数，进而使用该第一传输参数在该子带上发送上行信息。例如，对于子带A，第一RS包含RS#A(和对应的时频资源#A)和RS#B(和对应的时频资源#B)，第一终端设备在时频资源#A上对RS#A 进行测量得到接收干扰信道矩阵#A(记为G1)，在时频资源#B上对RS#B进行测量得到接收干扰信道矩阵#B(记为G2)，则对接收干扰信道#A和#B进行聚合后得到信道矩阵G＝[G1,G2]，其中G1、G2为S*L1和S*L2维的复数矩阵，S为第一终端的接收天线端口数目，L1、L2为RS#A和RS#B上测量得到的干扰流数。最后，根据聚合后的信道矩阵G得到第一干扰信道矩阵，根据第一干扰信道矩阵确定该子带A上传输参数。
可选的，在第一网络设备向第一终端设备发送第一指示信息之前，第一网络设备还可以向第一终端设备发送第一配置信息，该第一配置信息用于指示M个RS。或者说，第一配置信息用于指示一个RS集合，该RS集合中包括M个RS，M为正整数。相应的，第一终端设备可以接收来自第一网络设备的第一配置信息。随后，第一终端设备可根据该第一配置信息的指示，确定所述M个RS中每个RS所在的时频资源和/或每个RS的发送序列。
具体的，在一种可能的实施方式中，第一配置信息指示M个RS可以为:第一配置信息中包括M个RS的标识，每个RS的标识与一个RS配置信息相关联，该RS配置信息用于指示对应RS所在的时频资源和/或该RS的发送序列。可以理解，该实施方式可以认为是第一配置信息间接指示了M个RS中每个RS所在的时频资源和/或发送序列。如此，终端设备可根据第一配置信息中包括的M个RS的标识，获取所述M个RS分别关联的RS配置信息，进而根据所述M个RS分别关联的RS配置信息，确定所述M个RS中每个RS所在的时频资源和/或发送序列。
需要说明的是，所述M个RS中每个RS的标识与其对应的RS配置信息之间的关联关系可以是协议预定义或第一网络设备通过高层信令预配置给第一终端设备的，或者也可以是第一网络设备通过物理层信令向该第一终端设备指示的，再或者还可以是第一终端设备通过其他方式获取的，本申请并不限定。
在另一种可能的实施方式中，第一配置信息指示M个RS还可以为：第一配置信息中包括M个RS的标识和所述M个RS中的每个RS关联的RS配置信息，该RS配置信息用于指示对应RS所在的时频资源和/或该RS的发送序列。可以理解，该实施方式可以认为是第一配置信息直接指示了M个RS中每个RS所在的时频资源和/或发送序列。如此，终端设备接收到该第一配置信息后，可根据该第一配置信息直接确定出所述M个RS中每个RS所在的时频资源和/或发送序列。
进一步的，第一终端设备确定所述M个RS中每个RS所在的时频资源和/或RS的发送序列之后，可以测量所述M个RS中的至少一个RS，得到所述至少一个RS中的每个RS对应的干扰信息，即每个RS对应的干扰信道的信息。可选的，第一终端设备可以测量所述M个RS中的每个RS，得到所述M个RS中的每个RS对应的干扰信息，即M个RS对应的干扰信道的信息。
示例性的，对于所述M个RS中的其中一个RS来说，第一终端设备测量该RS，并得到该RS对应的干扰信道的信息具体可以为：如果该RS为NZP-RS，且第一配置信息中指示了该RS的发送序列(包括直接指示和间接指示)，则第一终端设备可以根据在该RS所在的时频资源上接收到的信号和该RS的发送序列，进行信道估计，然后得到该RS对应的干扰信道的信息。如果该RS是ZP-RS，即第一配置信息中未指示该RS的发送序列，则第一终端设备可以根据在RS占据的时频资源上接收到的数据信号或参考信号，估计干扰信道，得到该RS对应的干扰信道的信息；或者，第一终端设备可以根据在该RS占据的时频资源上接收到的数据信号或参考信号，计算干扰自相关矩阵，然后根据该干扰自相关矩阵， 计算干扰信道，得到该RS对应的干扰信道的信息。
可选的，该RS所在的时频资源在频域上可以包括多个子带，第一终端设备可以在每个子带上均测量得到一个对应的干扰信道的信息。
本申请实施例中，所述M个RS可以与M个终端设备一一对应。所述第一RS为所述M个RS之一，具体为M个终端设备中的第二终端设备对应的RS。所述M个终端设备为第一网络设备邻近的一个或多个其他网络设备管理的终端设备，所述M个终端设备的具体设备形态可参考上文中对第二终端设备的描述，在此不再赘述。
可以理解，第一配置信息可指示该第一RS。例如，第一配置信息中可包括该第一RS的标识，该第一RS的标识与该第一RS的RS配置信息相关联，该第一RS的RS配置信息用于指示该第一RS所在的时频资源和/或该第一RS的发送序列。
或者，该第一配置信息可指示该第一RS，以及该第一RS所在的时频资源和/或该第一RS的发送序列。例如，该第一配置信息中可包括该第一RS的标识以及该第一RS的RS配置信息，该第一RS的RS配置信息用于指示该第一RS所在的时频资源和/或该第一RS的发送序列。
由此可知，本申请实施例中，当第一终端设备将要在第一时频资源发送上行信息时，第一网络设备可以根据邻近的第二网络设备的资源分配情况，确定出与第一终端设备占据相同的第一时频资源的第二终端设备，并通过第一指示信息将该第二终端设备对应的第一RS指示给第一终端设备。如此，第一终端设备可在接收到该第一指示信息后，测量第一RS对应的干扰信道，并根据测量到的干扰信道在发送上行信息时主动调整传输参数，例如调整预编码矩阵，从而规避对占据相同的时频资源的第二终端设备的干扰。
在传统的上行传输中，终端设备发送上行信息时使用的预编码矩阵通常是指向目标网络设备的，即预编码矩阵的特征方向与终端设备到目标网络设备的信道的特征方向对齐。而本申请实施例中，第一网络设备可以通过指示第一RS，隐式地告诉第一终端设备与其占用相同的时频资源的第二终端设备的干扰信道，第一终端设备可以在原始预编码矩阵的基础上，对第一网络设备指示的干扰信道进行干扰迫零(zero-forcing)，相应调整发送上行信息时使用的波束或预编码矩阵，从而避免对第二终端设备造成干扰。
举例来说，在图6中，TRP#1为支持eMBB业务的网络设备，UE1为支持eMBB业务的终端设备，UE1接入TRP1，由该TRP1为其提供控制和数据服务，作为一种示例，图6中所示的UE1为具有摄像和视频上传功能的监控设备。TRP#2为支持URLLC业务的网络设备，UE2(包括图6中所示的UE2-1至UE2-K)为支持URLLC业务的终端设备，作为一种示例，图6中所示的UE2为应用在工业自动化控制场景中的机械手臂。在具体的应用场景中，UE2的部署具有高密度的特征，因此在一个UE1的周围可能分布着多个UE2，如图6中所示的UE2-1至UE2-K，K为正整数。
由UE1和UE2的业务特性可知，UE1需要将拍摄到的监控录像发送给TRP#1，而UE2(如图6中所示的UE2-1至UE2-K)需要从TRP#2接收实时的机械控制指令。为了避免UE1在上传监控录像时对UE2接收机械控制指令造成干扰，TRP#1可以从TRP#2获取TRP#2的调度信息，根据TRP#2的调度信息，确定在UE1进行上行传输时与UE1占用同样的时频资源进行下行传输的UE2为UE2-1。如此，TRP#1可以向UE1指示该UE2-1对应的RS 1，以便UE1测量该RS 1，得到对应的干扰信道的信息，进而在发送上行信息时对该干扰信道进行干扰迫零，例如可以调整在发送上行信息时使用的预编码矩阵或波束 方向，从而规避对UE2-1的干扰。
本申请实施例还关注在支持不同业务的终端设备之间形成的另一种干扰。
如图7所示，TRP1和UE1支持上行大容量业务，使用图1所示的帧结构2；TRP2和UE2支持URLLC业务，使用图1所示的帧结构3。根据UE1和UE2的业务特性并结合帧结构2和3可知，UE1的数据传输是基于时隙的(slot-based)，针对帧结构2中的一个时隙，该时隙的传输方向是单一的，即该时隙要么为上行时隙，要么为下行时隙，或者说该时隙中除灵活符号(用于上下行转换)之外的其他符号只会是上行符号或下行符号中的其中一种，不会同时包括上行符号和下行符号。而UE2由于URLLC业务的低时延要求，UE2的数据传输是基于子时隙(sub-slot based)或半时隙的，帧结构3的一个时隙中具有两种传输方向，即该时隙中既包括上行符号也包括下行符号。
因此，当UE1和UE2使用的时频资源发生重叠时，在重叠区域的每个时隙中，由于UE2的传输方向会发生变化，UE2对UE1造成的干扰的方向也随之变化。UE1在一个时隙中可能会先后经历同向干扰和异向干扰，UE1基于前面的DMRS测量到的干扰信道与后面的干扰信道不同，UE1根据该干扰信道做干扰破零，无法完全消除UE2对其造成的干扰。
鉴于此，针对终端设备在一个时间单元中会经历不同传输方向的干扰的问题，本申请实施例提供了另一种干扰控制方法。
请参考图8，为本申请实施例提供的另一种干扰控制方法的流程示意图，该方法包括：
步骤S801、第一网络设备向第一终端设备发送第三指示信息，该第三指示信息用于指示第一时间单元中包括的N个时域区间，该N个时域区间中的每个时域区间包括时域上连续的一个或多个符号，且不同的时域区间在时域上互不重叠，所述N为大于或等于2的正整数。本申请实施例中的符号可以是正交频分复用(orthogonal frequency division multiplexing，OFDM)符号或单载波频分复用(single carrier-frequency division multiplexing，SC-FDM)符号。
相应的，第一终端设备可以接收来自第一网络设备的第三指示信息。
本申请实施例中，所述第一网络设备为第一终端设备的服务网络设备，或者也可以称为服务基站或服务节点。即，第一终端设备接入第一网络设备，由第一网络设备为其提供控制和数据服务。
所述第一时间单元为时隙、子帧或无线帧，或者也可以是其他的时间调度单元，本申请并不限定。
在所述N个时域区间中的不同的时域区间内，第一终端设备接收到的干扰信号不同。因此，所述N个时域区间也可以认为是第一时间单元内的N个干扰区间。具体来说，所述干扰信号不同可以是指干扰信号的强度不同、或干扰信号的方向不同、或干扰信号的自相关矩阵不同中的一种或多种。因此，这需要第一终端设备在所述N个时域区间中的每个时域区间中分别测量干扰信号，并相应做干扰迫零处理，而不可以跨时域区间做干扰平滑。
所述第一指示信息可以是网络设备通过高层信令或物理层信令发送的，本申请并不限定。
步骤S802、第一网络设备在所述N个时域区间上，向第一终端设备发送下行数据。
所述下行数据可以承载在PDSCH上。
步骤S803、第一终端设备根据在第一时域区间内接收的参考信号和/或数据信号，确 定干扰自相关矩阵，该第一时域区间为所述N个时域区间中的一个。
步骤S804、第一终端设备根据所述干扰自相关矩阵，在第一时域区间上接收来自第一网络设备的下行数据。
需要说明的是，本申请实施例中是以N个时域区间中的第一时域区间为例来说明第一终端设备的下行数据接收过程。考虑到第一时间单元中包括N个时域区间，且N个时域区间内该第一终端设备受到的干扰不同，第一终端设备需要独立测量第一时间单元中的每个时域区间内的干扰信道，并针对每个时域区间内的干扰信道相应做干扰迫零处理。也就是说，第一终端设备可以针对所述N个时域区间中的每个时域区间分别执行如步骤S803和步骤S804所述的处理。
由此可知，本申请实施例中，当第一终端设备的相邻节点采用sub-slot级的DL-UL配置时，第一终端设备的下行数据接收在1个时隙内会受到来自该相邻节点的下行传输造成的同向干扰，以及该相邻节点的上行传输造成的异向干扰。该相邻节点可以是终端设备或网络设备或其他类型的设备，本申请并不限定。
这种情况下，第一网络设备可以向第一终端设备指示第一时间单元中包括的N个时域区间，该N个时域区间可以根据该相邻节点的DL-UL配置确定，或者也可以理解为第三指示信息是该相邻节点在第一时间单元内的干扰区间信息。如此，可以使第一终端设备在第一时间单元内的不同时域区间中分别测量干扰，从而获取到精确的干扰信息，更好地进行多天线均衡接收。
举例来说，第一时间单元为一个时隙，该时隙包括2个时域区间，分别称为第一时域区间和第二时域区间。其中，该时隙共包括14个符号，第一时域区间包括该时隙中的前7个符号，第二时域区间包括该时隙中的后7个符号。
假设TRP1为UE1调度的PDSCH占满该时隙。如图9a所示，如果该PDSCH在第一时域区间和第二时域区间中都有TRP 1发给UE 1的DMRS，则UE1可以根据第一时域区间(即该时隙的前7个符号)内的DMRS 1，进行信道估计和干扰测量，获取估计信道和第一干扰自相关矩阵，然后基于该第一干扰自相关矩阵进行前7个符号上的下行数据的多天线均衡接收。类似的，UE1可以根据第二时域区间(即该时隙的后7个符号)内的DMRS2，进行信道估计和干扰测量，获取估计信道和第二干扰自相关矩阵，然后基于该第二干扰自相关矩阵进行后7个符号上的下行数据的多天线均衡接收。可以理解，第一干扰自相关矩阵是根据第一时域区间内的DMRS1确定的，与第二时域区间内的DMRS2无关，反之亦然。
如图9b所示，如果该PDSCH仅在第一时域区间内有DMRS，则UE1可以根据第一时域区间(即该时隙的前7个符号)内的DMRS 1，进行信道估计和干扰测量，获取估计信道和第一干扰自相关矩阵，然后基于该第一干扰自相关矩阵进行前7个符号上的下行数据的多天线均衡接收。针对第二时域区间(即该时隙的后7个符号)，UE1可以根据在该第二时域区间内接收到的信号，进行信道估计、干扰测量和数据接收联合处理。应注意，所述联合处理与第一干扰自相关矩阵无关。
