Description

用于网络控制端和网络节点的电子设备和方法
本申请要求于2016年11月24日提交中国专利局、申请号为201611052958.0、发明名称为“用于网络控制端和网络节点的电子设备和方法”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
本发明的实施例总体上涉及无线通信领域，具体地涉及无线通信中的干扰处理，更具体地涉及一种用于网络控制端和网络节点的电子设备和方法。
背景技术
在3D-MIMO(Multiple In Multiple Out，多输入多输出)的实际场景下，可以利用垂直维度的信道，基站支持垂直维度的波束赋形(beam-forming)。这可以提高分布在高楼建筑中用户的服务质量(Quality of Service，QoS)。传统的水平维度的波束赋形的下倾角是固定的。因此可能会覆盖到邻小区的边缘用户，引起小区间干扰。而在垂直维度的波束赋形的情况下，服务高层建筑中的用户的垂直波束因其下倾角较大可能会对邻小区的边缘用户造成更大的影响。
图1示出了发生这种干扰的一个示例性场景的图。如图1所示，在波束赋形信道状态信息参考信号(Channel Status Information Reference Signal，CSI RS)为K>1Class B的情况下，基站2(BS2)配置K个CSI RS，分别指向不同的波束方向，其中包括不同的垂直波束方向。但是，某一方向的波束可能会覆盖到邻小区的某个用户，此时可以认为该波束对邻小区造成了比较强的干扰。例如，如图1所示，为高层建筑中的用户设备2(UE2)服务的波束对邻小区的UE1造成了干扰，即趋近于水平方向的波束可能会造成严重的小区间干扰。此外，为UE3服务的波束也可能会对邻小区的UE1造成强干扰。

根据本申请的另一个方面，提供了一种用于网络控制端的电子设备，包括：处理电路，被配置为：从本网络控制端所服务的网络节点获取网络节点对本网络控制端使用的CSI RS端口的RSRP的测量结果；以及基于测量结果产生第一指示信息，该第一指示信息指示本网络控制端所使用的CSI RS端口的干扰状态。
根据本申请的另一个方面，提供了一种用于网络节点的电子设备，包括：处理电路，被配置为：评估网络节点的服务质量；在服务质量低于预定水平时，测量网络节点使用的CSI RS端口的RSRP；以及基于测量的结果生成指示CSI RS端口的干扰状态的信息。

具体实施方式
在下文中将结合附图对本发明的示范性实施例进行描述。为了清楚和简明起见，在说明书中并未描述实际实施方式的所有特征。然而，应 该了解，在开发任何这种实际实施例的过程中必须做出很多特定于实施方式的决定，以便实现开发人员的具体目标，例如，符合与系统及业务相关的那些限制条件，并且这些限制条件可能会随着实施方式的不同而有所改变。此外，还应该了解，虽然开发工作有可能是非常复杂和费时的，但对得益于本公开内容的本领域技术人员来说，这种开发工作仅仅是例行的任务。
在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本发明，在附图中仅仅示出了与根据本发明的方案密切相关的设备结构和/或处理步骤，而省略了与本发明关系不大的其他细节。
<第一实施例>
如前所述，由于垂直维度的波束赋形的应用，可能造成小区间的强干扰，此外，在其他情形中，也可能存在小区间的明显干扰。更一般地，即使在不存在小区的概念的情形中，网络控制端的服务区域之间也可能由于波束赋形等因素而存在干扰，例如，某一网络控制端所使用的波束覆盖或部分覆盖相邻网络控制端的某一网络节点，从而对该网络节点造成严重干扰。因此，干扰情形是否存在的判断和干扰波束的确定对于通信质量和效率的提高有重要意义。
其中，网络控制端可以指通信系统中用于实现通信活动的相关设置、控制、通信资源分配等功能的实体，比如蜂窝通信系统中的基站，C-RAN(Cloud-RAN/Centralized-RAN)结构下(可能不存在小区概念)的基带云设备，例如C-RAN架构下的彼此高速连通的BBU池中的任一BBU等。网络节点可以指通信系统中使用通信资源以实现其通信目的的实体，比如各种用户设备(诸如具有蜂窝通信能力的移动终端、智能车辆、智能穿戴设备等)或者网络基础设施比如小小区基站等。
图2示出了根据本申请的一个实施例的用于网络控制端的电子设备100的功能模块框图，如图2所示，该电子设备100包括：第一确定单元101，被配置为基于来自相邻网络控制端的第一指示信息，确定本网络控制端所服务的网络节点要测量其参考信号接收功率(Reference Signal Receiving Power，RSRP)的CSI RS端口，其中，第一指示信息指示相 应的相邻网络控制端所使用的CSI RS端口的干扰状态；以及第二确定单元102，被配置为基于来自网络节点的测量结果，确定对网络节点产生干扰的相邻网络控制端及其CSI RS端口。
例如，在结合图1的场景考虑时，该电子设备100可以位于基站中或通信地连接到基站，网络节点可以为用户设备UE。应该注意，虽然在本说明书中为了便于理解可能结合图1的场景进行描述，但是本领域的技术人员应该理解，本申请的实施例的应用场景并不限于此，而是可以适用于任何相邻网络控制端的服务区域之间存在干扰的情形。
其中，第一确定单元101和第二确定单元102例如可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片。
网络节点可以通过测量CSI RS端口的RSRP来获知相应的CSI RS端口的接收功率水平。例如，对于本网络节点(及本网络控制端)使用的CSI RS端口而言，其发射功率不为0，这些端口为NZP(non-zero power)CSI RS端口，在正常情况下，这样的CSI RS端口的RSRP应该较高。反之，对于本网络节点(及本网络控制端)不使用的CSI RS端口而言，其发射功率为0，这些端口为ZP(zero power)CSI RS端口，在正常情况下，这样的CSI RS端口的RSRP应该较低。
在本实施例中，网络控制端所服务的网络节点并不需要测量所有的CSI RS端口的RSRP，而是仅测量特定的CSI RS端口的RSRP。其中，要测量的CSI RS端口是由第一确定单元101根据从相邻网络控制端接收到的第一指示信息来确定的。该第一指示信息指示了相应的相邻网络控制端所使用的CSI RS端口的干扰状态，其例如由相邻网络控制端的网络节点通过对其NZP CSI RS端口的RSRP的测量获得。该第一指示信息例如可以用来指示相邻网络控制端所使用的CSI RS端口中可能对本网络控制端的网络节点产生干扰的CSI RS端口。
在一个示例中，第一指示信息指示相邻网络控制端所使用的CSI RS端口中相应的RSRP低于第一预定阈值的CSI RS端口的信息，并且第一确定单元101被配置为将RSRP低于第一预定阈值的CSI RS端口确定为网络节点要测量的CSI RS端口。
如前所述，相邻网络控制端所使用的CSI RS端口对该相邻网络控制 端而言为NZP CSI RS，如果所测量的某一NZP CSI RS端口的RSRP过低，则意味着该CSI RS端口对应的波束的一部分功率可能被其他网络控制端(例如电子设备100对应的本网络控制端)所服务的网络节点接收到，即，该CSI RS端口对应的波束可能对其他网络控制端的网络节点造成了干扰。因此，将这样的CSI RS端口的信息包含在第一指示信息中并提供给其他网络控制端(例如电子设备100对应的本网络控制端)。
其中，NZP CSI RS端口的RSRP是否过低可以用第一预定阈值来衡量。该第一预定阈值例如可以根据上述相邻网络控制端的发射功率设置。
此外，第一指示信息还可以包括RSRP低于第一预定阈值的CSI RS端口与波束的对应关系的信息，该信息例如可以用于确定产生干扰的波束。
如图3所示，电子设备100还可以相应地包括：收发单元103，被配置为从相邻网络控制端接收第一指示信息。示例性地，收发单元103可以被配置为经由X2接口来接收第一指示信息。其中，收发单元103例如可以实现为通信接口。
进一步地，接收到第一指示信息的网络控制端指示其服务的网络节点对第一指示信息中包含的CSI RS端口的RSRP进行测量。对于该网络控制端而言，这些CSI RS端口是不被使用的，即为ZP CSI RS端口。因此，如果所测得的RSRP较高，说明受到了来自其他网络控制端的波束的干扰。这样，通过对上述CSI RS端口的RSRP的测量，第二确定单元102可以判断本网络节点是否受到了来自相邻网络控制端的干扰，并且可以确定具体哪个或哪些CSI RS端口产生了干扰。另外，网络控制端之间可以交互各自的CSI RS配置信息，例如，网络控制端可以从第一指示信息的接收中获得相邻网络控制端与其使用的CSI RS端口中待测量的CSI RS端口的信息。因此，网络控制端已知相邻网络控制端与待测量的CSI RS端口的对应关系，从而可以根据产生干扰的CSI RS端口来确定这些端口属于哪一个相邻网络控制端。
在一个示例中，网络节点的测量结果可以包括所测量的RSRP高于第二预定阈值的CSI RS端口的至少一部分的端口号的信息。第二预定阈值也可以基于网络控制端的发射功率来设置。如前所述，当所测量的 RSRP高于第二预定阈值时，说明其对应的CSI RS端口受到了相邻网络控制端的干扰。当存在多个RSRP高于第二预定阈值的CSI RS端口时，网络节点可以仅将部分CSI RS端口的端口号发送给网络控制端，比如可以仅发送RSRP最大的CSI RS端口的端口号。
该端口号例如用信号M来表示，即，M可以为相应的端口号。例如，在目前的协议中，CSI RS端口为从15到22，每个端口都有一个对应的端口号，端口15的端口号为1，端口16的端口号为2，以此类推。
假设每个网络控制端最多配置R个CSI RS端口，则信号M可以包括用来指示引起干扰的CSI RS端口的
Figure PCTCN2017109296-appb-000001
比特的信息元素。在R为16的情况下，M可以包括4比特的信息元素。
第二确定单元102可以对信号M进行分析，以获得产生干扰的CSI RS端口的信息，并且根据相邻网络控制端与CSI RS端口的对应关系来确定产生干扰的相邻网络控制端。
或者，信号M也可以包括两部分，分别用来指示引起干扰的网络控制端和该网络控制端的产生干扰的CSI RS端口。假设有N个相邻网络控制端，每个网络控制端最多配置R个CSI RS端口，则信号M可以包括如下比特数量的信息元素：用来指示引起干扰的网络控制端的
Figure PCTCN2017109296-appb-000002
比特，用来指示引起干扰的CSI RS端口的
Figure PCTCN2017109296-appb-000003
比特。在N为6和R为16的情况下，M可以包含7比特信息，其中3比特用来指示引起干扰的网络控制端，4比特用来指示引起干扰的CSI RS端口。
在该情况下，第二确定单元102可以对信号M进行分析，以获得产生干扰的相邻网络控制端及其CSI RS端口的信息。
另外，第二确定单元102还可以根据第一指示信息中的端口与波束的对应关系的信息，来确定与产生干扰的CSI RS端口对应的干扰波束。例如，假设波束b使用的端口分别为15、16、17、18，在端口15为产生干扰的CSI RS端口的情况下，由于波束b使用的是端口15，则认为波束b为干扰波束。
此外，如图4中所示，电子设备100还可以包括：生成单元104，被配置为生成针对对网络节点产生干扰的相邻网络控制端的干扰指示信息，以用于指示对网络节点产生干扰的CSI RS端口。
虽然图4中未示出，但是电子设备还可以包括图3中所示的收发单元103。相应地，收发单元103可以被配置为将干扰指示信息发送至相邻网络控制端。其中，生成单元104例如可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片。
在一个示例中，生成单元104可以根据第二确定单元102如上所述对信号M的分析结果来生成干扰指示信息。
换言之，干扰指示信息包括引起干扰的CSI RS端口号。例如，干扰指示信息可以用信号C表示，在信号M仅包括CSI RS端口号的情况下，信号C与信号M相同，在信号M还包括产生干扰的相邻网络控制端的指示比特的情况下，信号C例如为信号M的后
Figure PCTCN2017109296-appb-000004
比特。
另一方面，在相邻网络控制端接收到干扰指示信息后，可以根据其中的CSI RS端口的信息确定产生干扰的波束。例如，假设波束b使用的端口分别为15、16、17、18，在信号C表示的端口号为0001的情况下，表明端口15为产生干扰的CSI RS端口。相应地，确定波束b为产生干扰的波束。
示例性地，为了减轻或消除干扰，相邻网络控制端可以将该产生干扰的波束由波束赋形CSI RS切换为非预编码(non-precoded)CSI RS或者与本网络控制端对该波束进行分时复用。
生成单元104可以被配置为在每接收到一个网络节点的测量结果时分别生成一条干扰指示信息，也可以将一定时间内收到的测量结果进行汇总以生成一条干扰指示信息。在后一种情形下，例如，可以针对在一定时间内接收到的针对同一相邻网络控制端的同一CSI RS端口的所有测量结果生成一条干扰指示信息，或者，可以仅在一定时间内接收到针对同一相邻网络控制端的同一CSI RS端口的测量结果的数量超过预定数目时才生成相应的一条干扰指示信息。具体的生成方式可以取决于实际应用的场景和要求来确定。
此外，生成单元104还被配置为：在接收单元103在生成单元104生成干扰指示信息后的第一预定时间段内没有接收到来自相邻网络控制端的第一指示信息的情况下，将干扰指示信息修改为不包括任何CSI RS端口的形式，以指示相邻网络控制端。
即，如果在第一预定时间段内没有收到第一指示信息，说明在该段时间内不存在相互干扰，则可以将干扰指示信息设置为空，这样，相邻网络控制端在接收到新的干扰信息之后可以恢复之前操作的波束的正常使用，例如，切换回波束赋形CSI RS或停止分时复用。应该理解，生成单元104也可以生成其他形式的信号来指示相邻网络控制端恢复波束的正常使用。
根据本实施例的电子设备100能够通过网络节点对特定CSI RS端口的RSRP的测量结果，来确定对网络节点造成干扰的相邻网络控制端及其CSI RS端口，有助于减小网络控制端的服务区域之间的干扰。
<第二实施例>
图5示出了根据本申请的另一个实施例的用于网络控制端的电子设备200的功能模块框图，如图5所示，电子设备200包括：获取单元201，被配置为从本网络控制端所服务的网络节点获取网络节点对本网络控制端使用的CSI RS端口的RSRP的测量结果；以及生成单元202，被配置为基于测量结果产生第一指示信息，该第一指示信息指示本网络控制端所使用的CSI RS端口的干扰状态。
其中，获取单元201和生成单元202例如可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片。
网络节点在满足特定条件时对本网络控制端使用的CSI RS端口的RSRP进行测量，并且将测量结果提供给本网络控制端。该特定条件例如为网络节点的QoS下降到预定水平以下。
如前所述，本网络控制端使用的CSI RS端口为NZP CSI RS。在网络节点测量的RSRP过低比如低于第一预定阈值时，说明该CSI RS端口对应的波束可能被其他网络控制端的网络节点接收到，即可能对其他网络控制端的网络节点产生干扰，其中第一预定阈值可以根据网络控制端的发射功率设置。因此，在一个示例中，网络节点可以将该CSI RS端口的信息作为测量结果发送给网络控制端。
例如，网络节点可以将上述CSI RS端口的信息用比特序列或比特位图表示。具体地，可以将RSRP低于第一预定阈值的CSI RS端口对应 的比特位设置为0，其余比特位设置为1。
在获取单元201获取包含上述CSI RS端口的信息的测量结果之后，生成单元202可以相应地生成第一指示信息，该第一指示信息指示本网络控制端使用的CSI RS端口的干扰状态，例如可以包括可能对相邻网络控制端的网络节点产生干扰的波束所对应的CSI RS端口的信息。该第一指示信息用于指示相邻网络控制端对这些CSI RS端口的RSRP的进行测量，以确定是否确实产生干扰。
获取单元201可以基于每一个网络节点的测量结果生成第一指示信息，也可以仅在多于或等于预定数目的网络节点的测量结果一致的情况下，产生第一指示信息。
相应地，如图6所示，电子设备200还可以包括：收发单元203，被配置为从网络节点接收测量结果以及向相邻网络控制端发送第一指示信息。该第一指示信息例如可以包括网络控制端所使用的CSI RS端口中相应的RSRP低于第一预定阈值的CSI RS端口的信息。此外，该第一指示信息还可以包括这些CSI RS端口与波束的对应关系的信息。
在相邻网络控制端接收到第一指示信息之后，可以根据其中的干扰状态信息指示其服务的网络节点进行相应的CSI RS端口的RSRP的测量，从而例如根据测量结果确定哪些CSI RS端口的确受到了干扰。例如可以采用第一实施例中所述的判断方式，即认为所测量的RSRP高于第二预定阈值的CSI RS端口为受到干扰的CSI RS端口。随后，相邻网络控制端将受到干扰的CSI RS端口的信息包括在干扰指示信息中，以提供给本网络控制端。
相应地，收发单元203还可以被配置为从相邻网络控制端接收干扰指示信息，该干扰指示信息指示本网络控制端的CSI RS端口中对相邻网络控制端所服务的网络节点产生干扰的CSI RS端口。与第一实施例中类似，干扰指示信息例如可以用信号C表示，信号C为相应的CSI RS端口的端口号。
如图6中的虚线框所示，电子设备200还可以包括：确定单元204，被配置为基于干扰指示信息，确定对相邻网络控制端所服务的网络节点产生干扰的干扰波束。具体地，确定单元204可以根据本网络控制端的 CSI RS端口与波束之间的对应关系，来确定与干扰指示信息中包括的CSI RS端口对应的波束作为干扰波束。
例如，假设波束b使用的端口分别为15、16、17、18，在干扰指示信息表明端口15为产生干扰的CSI RS端口的情况下，相应地确定波束b为产生干扰的波束。
此外，确定单元204还可以被配置为将所确定的干扰波束从波束赋形CSI RS切换为非预编码CSI RS，或者与相邻网络控制端对该干扰波束进行分时复用。通过执行这样的处理，可以有效地减轻对相邻网络控制端的网络节点的干扰，提高整体通信质量。
在一个示例中，确定单元204还可以被配置为在第二预定时间段内接收到多于或等于预定数量的针对同一干扰波束的干扰指示信息时，执行上述切换处理或分时复用处理。例如，假设波束b使用的端口分别为15、16、17、18，预定数量为2，如果分别从两个相邻网络控制端接收到指示端口15和端口16的干扰指示信息或者从一个相邻网络控制端接收到指示端口15的两条干扰指示信息，由于针对这两条干扰指示信息，均可以相应地确定干扰波束为波束b，因此满足上述条件，执行切换处理或分时复用处理。
在这种情况下，本网络控制端的某个波束对多个相邻网络控制端产生干扰以及/或者对一个相邻网络控制端所服务的多个网络节点产生干扰，即该干扰波束的影响较大，仅对这样的干扰波束执行处理可以避免不必要的频繁的切换，有利于保持系统的稳定和高效。
此外，确定单元204还可以被配置为响应于来自相邻网络控制端的不包括任何CSI RS端口的干扰指示信息，将干扰波束从非预编码CSI RS切换为波束赋形CSI RS，或者停止对干扰波束进行分时复用。其中，不包括任何CSI RS端口的干扰指示信息指示了干扰状况不再存在，因此，本网络控制端可以恢复对干扰波束的正常使用。
应该理解，本实施例的电子设备200可以和第一实施例中的电子设备100共同用于网络控制端，也可以单独地使用，这并不是限制性的。
根据本实施例的电子设备200可以向相邻网络控制端提供其CSI RS端口的干扰状态，并且根据来自相邻网络控制端的干扰指示信息执行相 应的操作，以避免或减轻本网络控制端对相邻网络控制端的网络节点的干扰。
<第三实施例>
图7示出了根据本申请的一个实施例的用于网络节点的电子设备300的功能模块框图，该电子设备300包括：评估单元301，被配置为评估网络节点的服务质量；测量单元302，被配置为在服务质量低于预定水平时，测量网络节点使用的CSI RS端口的RSRP；以及生成单元303，被配置为基于测量的结果生成指示CSI RS端口的干扰状态的信息。
其中，评估单元301、测量单元302和生成单元303例如可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片。
此外，如图7中的虚线框所示，电子设备300还可以包括：收发单元304，被配置为将生成的指示CSI RS端口的干扰状态的信息发送给网络控制端。
评估单元301例如可以通过各种方式来评估网络节点的QoS。当QoS低于预定水平时，说明可能产生了网络控制端的服务区域之间的干扰。因此，测量单元302对网络节点使用的CSI RS端口的RSRP进行测量。例如，在某一CSI RS端口的RSRP的测量结果低于第一预定阈值时，认为该CSI RS端口对应的波束可能对其他相邻网络控制端的网络节点产生干扰。相应地，生成单元303可以生成指示该CSI RS端口的干扰状态的信息。例如，该信息可以包括指示所测量的RSRP小于第一预定阈值的CSI RS端口的信息。
在一个示例中，该信息可以具有比特序列或比特位图的形式，其中，所测量的RSRP小于第一预定阈值的CSI RS端口对应的比特为0，其余CSI RS端口对应的比特为1。
由以上描述可以看出，指示CSI RS端口的干扰状态的信息的生成和上报是基于触发式的，即，基于QoS的下降而触发的。网络控制端在接收到上报的该信息之后，根据该信息生成第一指示信息，以指示本网络控制端使用的CSI RS端口的干扰状态。该第一指示信息可以提供给其他相邻网络控制端，以使其针对其中包括的CSI RS端口进行RSRP测量。
相应地，本网络控制端也可以从相邻网络控制端接收其发送的第一指示信息。测量单元302还可以被配置为对网络控制端基于来自相邻网络控制端的第一指示信息确定的要测量的CSI RS端口的RSRP进行测量，并将测量的结果上报给网络控制端，其中，第一指示信息指示相应的相邻网络控制端所使用的CSI RS端口的干扰状态。
例如，第一指示信息中包括相邻网络控制端的CSI RS端口中相应的RSRP低于第一预定阈值的CSI RS端口的信息，测量单元302针对这些CSI RS端口进行RSRP的测量。
测量单元302可以将所测量的RSRP大于第二预定阈值的CSI RS端口的至少一部分的端口号的信息上报给网络控制端。对于网络节点而言，相邻网络控制端使用的CSI RS端口是ZP CSI RS端口，因此，当测量的RSRP较大(例如，大于第二预定阈值)时，说明受到了来自相邻网络控制端的波束的影响。测量单元302可以将这样的CSI RS端口的端口号上报给网络控制端，以使得网络控制端可以通知相应的相邻网络控制端该CSI RS端口对应的波束产生了干扰。
在一个示例中，测量单元302可以将所测量的RSRP大于第二预定阈值的CSI RS端口中RSRP最大的CSI RS端口的端口号的信息上报给网络控制端。
根据该实施例的电子设备300能够响应于服务质量的降低来确定CSI RS端口的干扰状态，为干扰的存在的确定提供依据，此外，电子设备300还能够对其他相邻网络控制端的特定CSI RS端口进行测量，确定产生干扰的其他相邻网络控制端及其CSI RS端口，从而有助于避免或减轻干扰。
为了便于理解，图8示出了网络控制端与网络节点之间的有关干扰避免或减轻的信息流程的示例。在图8中以一个产生干扰的网络控制端2(NC2)和一个被干扰的网络控制端1(NC1)为例进行了图示。但是，应该理解，该信息流程可以在多个网络控制端之间同时进行，此外，网络控制端所服务的网络节点也可以有多个。
如图8所示，NC2的网络节点(N2)评估其QoS，并且将其QoS与预定水平相比较，当QoS低于预定水平时，测量NC2和N2使用的 CSI RS端口的RSRP，并将其与第一预定阈值相比较。随后，N2将指示CSI RS端口的干扰状态的比特序列发送给网络控制端，该比特序列中对应于RSRP低于第一预定阈值的CSI RS端口的比特为0，对应于其余CSI RS端口的比特为1。NC2接收到N2的比特序列的上报之后，生成第一指示信息，该第一指示信息可以包括对应于比特为0的CSI RS端口的信息。接着，NC2将第一指示信息例如通过X2接口发送给NC1。NC1根据该第一指示信息确定其服务的N1要测量的CSI RS端口并向其发送指示。N1测量相应的CSI RS端口的RSRP并将测量的结果与第二预定阈值比较，将RSRP高于第二预定阈值的CSI RS端口中RSRP最高的CSI RS端口的端口号上报给NC1。NC1相应地生成针对NC2的干扰指示信息，该干扰指示信息中包括CSI RS端口的端口号。NC2根据该端口号可以确定产生干扰的干扰波束，并且通过将该干扰波束切换为非预编码CSI RS或者与NC1对该干扰波束进行分时复用，来消除或减轻干扰。
随后，N2继续评估其QoS，如果其在预定时间段内没有发现QoS低于预定水平，则不会向NC2上报比特序列，相应地，NC2不会生成和发送新的第一指示信息。在这种情况下，NC1在预定时间段内没有接收到来自NC2的新的第一指示信息，其对干扰指示信息进行修改以使其不包含任何CSI RS端口的信息并向NC2发送该修改的干扰指示信息。NC2在接收到该修改的干扰指示信息之后，将前述干扰波束切换回波束赋形CSI RS或者停止对该干扰波束的分时复用。
注意，NC1和NC2在功能上可以是对等的，即，NC1也可以执行NC2的功能，NC2也可以执行NC1的功能。类似地，N1和N2在功能上也是对等的，N1也可以执行N2的功能，N2也可以执行N1的功能。
当结合图1的场景时，NC1例如为BS1，N1例如为UE1，NC2例如为BS2，N2例如为UE2。但是，应该理解，本申请的实施例并不限于图1的场景，并且，可以采用的信息流程也不限于图8所示的那样，而是可以根据实际应用进行适当的修改。

在确定干扰波束之后，上述方法还可以包括S25：将所确定的干扰波束从波束赋形CSI RS切换为非预编码CSI RS，或者与相邻网络控制端对干扰波束进行分时复用。该步骤S25还可以在如下情况下执行：在第二预定时间段内接收到多于或等于预定数量的针对同一干扰波束的干扰指示信息时。
此外，虽然图10中未示出，但是上述方法还可以包括：响应于来自相邻网络控制端的不包括任何CSI RS端口的干扰指示信息，将干扰波束从非预编码CSI RS切换为波束赋形CSI RS，或者停止对干扰波束进行分时复用。

例如，上述信息可以包括指示所测量的RSRP小于第一预定阈值的CSI RS端口的信息。上述信息可以具有比特序列或比特位图的形式，其 中，所测量的RSRP小于第一预定阈值的CSI RS端口对应的比特为0，其余CSI RS端口对应的比特为1。
