Description

交调干扰指示方法及装置、基站和用户设备 技术领域
本公开涉及通信技术领域，尤其涉及一种交调干扰指示方法及装置、交调干扰结果反馈方法及装置、基站、用户设备和计算机可读存储介质。
背景技术
随着无线通信技术的飞速发展，出现了第五代移动通信技术(5th Generation，简称为5G)。在5G布局的前期会采用非独立(non-standalone，简称为NSA)的方式进行布网，而NSA方式是基于长期演进(Long Term Evolution，简称为LTE)-新空口(new radio，简称为NR)双连接的，这就需要用户设备(UE)同时维持两条通信链路，一条为LTE通信链路，一条为NR通信链路。
但是，如果UE在两个频段上同时进行上行传输，则有可能对某个频段的下行接收造成严重的交调干扰(Inter-Modulation Distortion，简称为IMD)，降低UE的性能，而这个问题对于6GHz以下的LTE频段和NR频段尤其严重。
因此，如果UE能够向基站上报自己在某些频段组合上的IMD问题，那么基站就可以避免为该UE配置会产生交调干扰问题的上行链路组合。但是，如果采用UE能力上报的方法来使UE向基站上报自己的能力，那么UE需要在附着阶段上报所有自己能够支持的频段组合，这样会造成很大的信令开销。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
图1是本申请一示例性实施例示出的一种交调干扰指示方法的流程图，该实施例从第一基站侧进行描述，如图1所示，该交调干扰指示方法包括：
在步骤S101中，当准备为UE配置第二基站时，向UE发送询问请求，该询问请求用于询问UE同时在第一基站和第二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生IMD。
其中，第一基站可以为LTE基站，第二基站可以为5G基站(gNB)，上行频段组合包括第一基站对应的一个上行频段和第二基站对应的一个上行频段，第一基站可以根据负载情况选择第二基站对应的一个上行频段，也可以随机从第二基站可以使用的上行频段中选择一个上行频段。
在该实施例中，当LTE基站准备为5G UE配置gNB为辅基站时，可以通过新的无线资源控制(RRC)信令向UE发送询问请求，以询问5G UE同时在第一基站和第二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生IMD。
其中，下行接收对应的频段是上行频段组合中任一上行频段对应的下行频段。
在步骤S102中，接收UE根据询问请求反馈的判断结果。
UE在接收到询问请求后，可以根据自己的实际实现情况来判断自己同时在第一基站和第二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生交调干扰，如果在某些频段组合上进行上行传输时会对下行接收产生交调干扰，则UE可以通过新的RRC信令向基站反馈产生交调干扰的频段信息。如果在某些频段组合上进行上行传输时不会对下行接收产生交调干扰，则UE可以通过新的RRC信令向基站反馈不会产生交调干扰。
在步骤S103中，根据接收到的判断结果在对应的频段上为UE配置上行传输和下行接收。
在该实施例中，若第一基站接收到的判断结果为产生IMD的频段信息，则可以在除产生IMD的频段之外的其他频段上为UE配置上行传输和下行接收，也即避免为该UE配置会产生交调干扰的频段，从而可以消除IMD，提升UE的性能。若第一基站接收到的判断结果为UE同时在上行频段组合进行上行传输时不会对下行接收产生IMD，则可以在上行频段组合上为UE配置上行传输和下行接收。
例如，若LTE基站接收到的判断结果为LTE的上行频段1和NR上行频段2为产生IMD的频段，则不可以同时在LTE的上行频段1和NR上行频段2为UE配置上行传输。若LTE基站接收到的判断结果为UE同时在上行频段1和NR上行频段2进行上行传输时不会对下行接收产生IMD，则可以同时在上行频段1和NR上行频段2上为UE配置上行传输。
需要说明的是，在一种是实施例中，第一基站在除产生IMD的频段之外的其他频段上为UE配置上行传输和下行接收之前，需要重复执行向UE发送询问请求和接收UE根据询问请求反馈的判断结果的操作，直至判断结果为UE同时在上行频段组合进行上行传输时不会对下行接收产生IMD，这样，可以避免产生IMD，其中，上行频段组合包括其他频段。
上述实施例，通过在准备为UE配置第二基站时，向UE发送询问请求，以询问UE同时在第一基站和第二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生IMD，并根据UE反馈的判断结果在对应的频段上为UE配置上行传输和下行接收，由于UE根据询问请求反馈判断结果，从而可以极大地节省系统信令开销，且可以避免出现交调干扰。
图2是本申请一示例性实施例示出的一种交调干扰结果反馈方法的流程图，该实施例从UE侧进行描述，如图2所示，该交调干扰结果反馈方法包括：
在步骤S201中，接收第一基站在准备为UE配置第二基站时发送的询问请求，该询问请求用于询问UE同时在第一基站和第二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生交调干扰。
其中，第一基站可以为LTE基站，第二基站可以为5G基站(gNB)，例如，当LTE基站准备为5G UE配置gNB为辅基站时，可以通过新的RRC信令向UE发送询问请求，UE接收该询问请求。
在步骤S202中，根据该询问请求判断UE同时在第一基站和第二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生交调干扰。
UE在接收到询问请求后，可以根据自己的实际实现情况来判断自己同时在第一基站和第二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生交调干扰。
在该实施例中，UE可以根据上行频段组合中两个上行频段的信息计算出IMD下限和IMD上限，若下行接收所在的频段位于IMD下限和IMD上限构成的频段区间，则可以确定同时在上行频段组合进行上行传输时会对下行接收产生交调干扰，否则，可以确定同时在上行频段组合进行上行传输时不会对下行接收产生交调干扰。
例如，上行频段组合为：上行频段1800-1810和上行频段3640-3660，则UE同时在上行频段组合进行上行传输，造成的IMD下限(IM2_low)为3640-1810＝1830,造成的IMD上限(IM2_high)为3660-1800＝1860，假设上行频段1800-1810对应的下行频段为1850-1860，由于1850-1860位于1830-1860中，则UE在这两个上行频段同时发送会对下行接收产生IMD干扰。
在步骤S203中，向第一基站反馈判断结果。
其中，UE可以通过新的RRC信令向第一基站反馈判断结果。
在该实施例中，如果在某些频段组合上进行上行传输时会对下行接收产生交调干扰，则UE可以通过新的RRC信令向基站反馈产生交调干扰的频段信息。如果在某些频段组合上进行上行传输时不会对下行接收产生交调干扰，则UE可以通过新的RRC信令向基站反馈不会产生交调干扰。
上述实施例，通过根据接收的询问请求判断UE同时在第一基站和第二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生交调干扰，并向第一基站反馈判断结果，从而可以极大地节省系统信令开销。
图3是本申请一示例性实施例示出的一种交调干扰结果反馈方法的信令流程图，该实施例从UE和基站交互的角度进行描述，如图3所示，该交调干扰结果反馈方法包括：
在步骤S301中，当第一基站准备为用户设备UE配置第二基站时，向UE发送询问请求，该询问请求用于询问UE同时在第一基站和第二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生交调干扰IMD。
在步骤S302中，UE接收第一基站发送的询问请求。
在步骤S303中，UE根据该询问请求判断UE同时在第一基站和第二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生交调干扰。
在步骤S304中，UE向第一基站反馈判断结果。
在步骤S305中，第一基站接收UE反馈的判断结果。
在步骤S306中，若第一基站接收到的判断结果为产生IMD的频段信息，则在除产生IMD的频段之外的其他频段上为该UE配置上行传输和下行接收，若第一基站接收到的判断结果为UE同时在上行频段组合进行上行传输时不会对下行接收产生IMD，则可以在上述上行频段组合上为UE配置上行传输和下行接收。
上述实施例，通过基站与UE之间的交互，使得UE可以根据基站发送的询问请求反馈判断结果，从而可以极大地节省系统信令开销，使得基站可以根据UE反馈的判断结果在对应的频段上为UE配置上行传输和下行接收，从而可以避免出现交调干扰。
图4是根据一示例性实施例示出的一种交调干扰指示装置的框图，该装置可以位于基站中，如图4所示，该装置包括：发送模块41、接收模块42和配置模块43。
发送模块41被配置为当准备为用户设备UE配置第二基站时，向UE发送询问请求，询问请求用于询问UE同时在第一基站和第二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生交调干扰IMD。
其中，第一基站可以为LTE基站，第二基站可以为5G基站(gNB)，上行频段组合包括第一基站对应的一个上行频段和第二基站对应的一个上行频段，第一基站可以根据负载情况选择第二基站对应的一个上行频段，也可以随机从第二基站可以使用的上行频段中选择一个上行频段。
在该实施例中，当LTE基站准备为5G UE配置gNB为辅基站时，可以通过新的无线资源控制(RRC)信令向UE发送询问请求，以询问5G UE同时在第一基站和第二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生IMD。
其中，下行接收对应的频段是上行频段组合中任一上行频段对应的下行频段。接收模块42被配置为接收UE根据发送模块41发送的询问请求反馈的判断结果。
UE在接收到询问请求后，可以根据自己的实际实现情况来判断自己同时在第一基站和第二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生交调干扰，如果在某些频段组合上进行上行传输时会对下行接收产生交调干扰，则UE可以通过新的RRC信令向基站反馈产生交调干扰的频段信息。如果在某些频段组合上进行上行传输时不会对下行接收产生交调干扰，则UE可以通过新的RRC信令向基站反馈不会产生交调干扰。
配置模块43被配置为根据接收模块42接收到的判断结果在对应的频段上为UE配置上行传输和下行接收。
在该实施例中，若第一基站接收到的判断结果为产生IMD的频段信息，则可以在除产生IMD的频段之外的其他频段上为UE配置上行传输和下行接收，也即避免为该UE配置会产生交调干扰的频段，从而可以消除IMD，提升UE的性能。若第一基站接收到的判断结果为UE同时在上行频段组合进行上行传输时不会对下行接收产生IMD，则可以在上行频段组合上为UE配置上行传输和下行接收。
上述实施例，通过在准备为UE配置第二基站时，向UE发送询问请求，以询问UE同时在第一基站和第二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生IMD，并根据UE反馈的判断结果在对应的频段上为UE配置上行传输和下行接收，由于UE根据询问请求反馈判断结果，从而可以极大地节省系统信令开销，且可以避免出现交调干扰。
图5是根据一示例性实施例示出的另一种交调干扰指示装置的框图，如图5所示，在 上述图4所示实施例的基础上，配置模块43可以包括：第一配置单元431和第二配置单元432。
第一配置单元431被配置为若接收模块42接收到的判断结果为产生IMD的频段信息，则在除产生IMD的频段之外的其他频段上为UE配置上行传输和下行接收。
第二配置单元432被配置为若接收模块42接收到的判断结果为UE同时在上行频段组合进行上行传输时不会对下行接收产生IMD，则在上行频段组合上为UE配置上行传输和下行接收。
例如，若LTE基站接收到的判断结果为LTE的上行频段1和NR上行频段2为产生IMD的频段，则不可以同时在LTE的上行频段1和NR上行频段2为UE配置上行传输。若LTE基站接收到的判断结果为UE同时在上行频段1和NR上行频段2进行上行传输时不会对下行接收产生IMD，则可以同时在上行频段1和NR上行频段2上为UE配置上行传输。
另外，第一配置单元431还可以配置为在除产生IMD的频段之外的其他频段上为UE配置上行传输和下行接收之前，重复调用发送模块41执行向UE发送询问请求和接收模块42执行接收UE根据询问请求反馈的判断结果的操作，直至判断结果为UE同时在上行频段组合进行上行传输时不会对下行接收产生IMD，其中，上行频段组合包括其他频段。
上述实施例，在判断结果为产生IMD的频段信息时，在除产生IMD的频段之外的其他频段上为UE配置上行传输和下行接收，也即避免为该UE配置会产生交调干扰的频段，从而可以消除IMD，在接收到的判断结果为UE同时在上行频段组合进行上行传输时不会对下行接收产生IMD时，在上行频段组合上为UE配置上行传输和下行接收，也即同时在上行频段组合上进行上行传输也不会产生IMD。
图6是根据一示例性实施例示出的一种交调干扰结果反馈装置的框图，该装置可以位于UE中，如图6所示，该装置包括：接收模块61、判断模块62和反馈模块63。
接收模块61被配置为接收第一基站在准备为UE配置第二基站时发送的询问请求，询问请求用于询问UE同时在第一基站和第二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生交调干扰。
其中，第一基站可以为LTE基站，第二基站可以为5G基站(gNB)，例如，当LTE基站准备为5G UE配置gNB为辅基站时，可以通过新的RRC信令向UE发送询问请求，UE接收该询问请求。
判断模块62被配置为根据接收模块61接收的询问请求判断UE同时在第一基站和第 二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生交调干扰。
UE在接收到询问请求后，可以根据自己的实际实现情况来判断自己同时在第一基站和第二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生交调干扰。
在该实施例中，UE可以根据上行频段组合中两个上行频段的信息计算出IMD下限和IMD上限，若下行接收所在的频段位于IMD下限和IMD上限构成的频段区间，则可以确定同时在上行频段组合进行上行传输时会对下行接收产生交调干扰，否则，可以确定同时在上行频段组合进行上行传输时不会对下行接收产生交调干扰。
例如，上行频段组合为：上行频段1800-1810和上行频段3640-3660，则UE同时在上行频段组合进行上行传输，造成的IMD下限(IM2_low)为3640-1810＝1830,造成的IMD上限(IM2_high)为3660-1800＝1860，假设下行频段为1850-1860，由于1850-1860位于1830-1860中，则UE在这两个上行频段同时发送会对下行接收产生IMD干扰。
反馈模块63被配置为向第一基站反馈判断模块62的判断结果。
其中，UE可以通过新的RRC信令向第一基站反馈判断结果。
在该实施例中，如果在某些频段组合上进行上行传输时会对下行接收产生交调干扰，则UE可以通过新的RRC信令向基站反馈产生交调干扰的频段信息。如果在某些频段组合上进行上行传输时不会对下行接收产生交调干扰，则UE可以通过新的RRC信令向基站反馈不会产生交调干扰。
上述实施例，通过根据接收的询问请求判断UE同时在第一基站和第二基站即将配置的上行频段组合进行上行传输时是否会对下行接收产生交调干扰，并向第一基站反馈判断结果，从而可以极大地节省系统信令开销。
