用于无线通信的电子设备和方法、计算机可读存储介质
本申请要求于2018年9月12日提交中国专利局、申请号为201811061539.2、发明名称为“用于无线通信的电子设备和方法、计算机可读存储介质”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
本申请涉及无线通信技术领域，具体地涉及无线通信系统中的干扰测量。更具体地，涉及一种用于无线通信的电子设备和方法以及计算机可读存储介质。
背景技术
新无线电(New Radio，NR)作为针对长期演进(Long Term Evolution，LTE)的下一代的无线接入方式，是与LTE不同的无线接入技术(Radio Access Technology，RAT)。在当前制定的5G标准中，增强了波束管理方面的机制，其中可以包括与干扰测量相关的增强。
例如，用户设备(User Equipment，UE)对物理层的参考信号接收功率(L1-Reference Signal Received Power，L1-RSRP)进行测量并将测量结果上报至基站，从而使得基站可以选择L1-RSRP较高的发射波束来执行与UE的通信。但是，L1-RSRP并不能反映来自邻小区的干扰波束所产生的影响，换言之，L1-RSRP较高的波束可能受到较强的来自邻小区的干扰，从而波束质量较差。
此外，用于移动性管理的高层干扰测量机制具有较长的测量和上报周期，并不适用于基于干扰感知的波束管理。

根据本申请的电子设备和方法通过执行干扰波束测量来测量邻小区的发射波束对服务小区的干扰程度，从而能够在考虑干扰的情况下更加准确地评估服务小区的各个波束的波束质量，进而实现更高效的波束管 理。

具体实施方式
在下文中将结合附图对本公开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公开，在附图中仅仅示出了与根据本公开的方案密切相关的设备结构和/或处理步骤，而省略了与本公开关系不大的其他细节。
<第一实施例>
图1示出了根据本申请的一个实施例的用于无线通信的电子设备100的功能模块框图，如图1所示，电子设备100包括：确定单元101，被配置为确定期望被用于干扰波束测量的邻小区的发送参考信号的资源，干扰波束测量用于测量邻小区的发射波束对服务小区的干扰程度；上报单元102，被配置为将所确定的资源的资源指示符上报至服务小区的基站；以及执行单元103，被配置为基于来自基站的配置信息执行干扰波束测量。
其中，确定单元101、上报单元102和执行单元103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、处理器。并且，应该理解，图1中所示的电子设备中的各个功能单元仅是根据其所实现的具体功能而划分的逻辑模块，而不是用于限制具体的实现方式。这同样适用于随后要描述的其他电子设备的示例。
电子设备100例如可以设置在用户设备(UE)侧或者可通信地连接到UE。这里，还应指出，电子设备100可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备100可以工作为用户设备本身，并且还可以包括诸如存储器、收发器(图中未示出)等外部设备。存储器可以用于存储用户设备实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，基站、其他用户设备等等)间的通信，这里不具体限制收发器的实现形式。这同样适用于随后关于用户设备侧的电子设备的其他配置示例的描述。
如前所述，期望以较低的时延获得邻小区的发射波束对服务小区产生的干扰的程度，从而实现考虑邻小区的干扰的情况下的波束管理。在本申请中，服务小区指的是UE当前所接入的小区，邻小区指的是与服务小区相邻的小区，其中，邻小区的发射波束会对服务小区的通信造成干扰。例如，当服务小区的基站使用发射波束beam1向UE传输数据时， 邻小区的基站的发射波束beam2可能同时被该UE所接收，从而造成干扰，降低通信质量。
因此，通过使得邻小区在期望的波束发送方向上发送参考信号，并且使得服务小区的UE对该参考信号进行测量，可以获得邻小区的发射波束对服务小区的干扰程度。这里所述的参考信号例如可以为同步信号(Synchronization Signal，SS)(或称为同步信号/物理广播信道(Synchronization Signal/Physical Broadcast Channel,SS/PBCH))，或者CSI-RS(Channel State Information Reference Signal)。
应该理解，在采用波束赋形技术的情况下，基站可以有多个波束发送方向，并且每一个波束发送方向与发送参考信号所使用的资源具有预定对应关系。在考虑空间位置等因素的情况下，邻小区的所有发射波束中可能只有一部分会对服务小区造成干扰，因此可以仅考虑这一部分发射波束，从而减轻测量负荷。
在本实施例中，确定单元101确定要用于干扰波束测量的邻小区的发送参考信号的资源，即确定邻小区的发射波束的方向。在一个示例中，确定单元101被配置为基于初始接入时收集的信息以及/或者移动性相关的配置来确定该资源。具体地，UE在初始接入时将测量来自多个小区的同步信号/物理广播信道(Synchronization Signal/Physical Broadcast Channel,SS/PBCH)并且选择信道质量最好的一个(即，服务小区)接入。相应地，UE将不参与服务该UE的其他小区作为可能会产生干扰的小区(也称为干扰小区)，并且例如可以存储各个干扰小区的波束相关信息或者资源指示符信息。确定单元101可以基于这些信息来选择邻小区最可能对服务小区产生干扰的一个或更多个发射波束的方向，即，确定相应的发送参考信号的资源。上报单元102将确定的资源的资源指示符上报至服务小区的基站，并由服务小区的基站例如经由Xn信令传递至邻小区的基站，以使得邻小区的基站与服务小区的基站达成共识并使用相应的资源发射专用参考信号(例如CSI-RS)供服务小区的UE进行测量。
相应地，执行单元103基于来自基站的配置信息执行干扰波束测量。可以理解，配置信息用于对干扰波束测量所采用的具体方式、执行测量所占用的资源等进行配置。例如，执行单元103可以经由无线资源控制(Radio Resource Control，RRC)信令来接收该配置信息。在执行单元 103完成干扰波束测量后，上报单元102还将干扰波束测量的测量结果上报至基站。借此，UE只须针对最可能对其产生干扰的一个或更多个邻小区波束进行测量，从而节省能耗，而邻小区基站也不必为了非服务用户占用过多资源发射干扰波束供其测量，从而降低参考信号资源开销。
为了便于理解，图2示出了服务小区的基站与UE之间的相关信息流程。如图2所示，在初始接入阶段，UE搜索并同步到当前服务小区，随后在下行链路中从服务小区的基站接收系统信息块(System Information Block，SIB)，选择当前服务小区并在上行链路中向基站发送物理随机接入信道(Physical Random Access Channel，PRACH)。在初始的小区搜索和选择过程中，UE轮番搜索每一载波并确定同步信号接收强度最强的小区作为服务小区，在这个过程中UE记录并存储观测到的较强载波对应的小区ID及其波束的指示符。接入成功后，UE进入RRC连接(RRC_Connected)状态。接下来，UE向基站报告其期望测量的邻小区的资源的资源指示符，例如报告之前存储的邻小区的小区ID及其波束的资源指示符。基站将干扰波束测量的配置信息发送给UE。UE根据该配置信息执行干扰波束测量，并且将测量结果上报至基站，以使得基站可以使用该测量结果进行波束管理。在本实施例中，UE执行了物理层的干扰测量和上报。
例如，配置信息可以包括如下中的一个或多个：服务小区的用于干扰波束测量的资源；邻小区的发送参考信号的资源；与干扰波束测量有关的周期性配置；干扰波束的扫描(sweeping)机制；参考信号的类别。注意，这些配置信息可以包含在一条信令(比如RRC信令)中，也可以包含在多条信令中(比如RRC信令和MAC信令结合)。
在另一个示例中，UE在完成接入并与服务基站进行通信后，将根据服务基站的配置进行移动性相关的高层测量，例如测量邻小区的信号强度并与服务小区的信号强度进行比较用以基站判断是否需要切换到其他小区进行服务。在这个过程中，UE需要对基站配置的多个邻小区频率进行测量进而能够储存测量到的较强频率对应的小区ID及其波束作为历史信息，以用于筛选并报告服务基站要测量的干扰波束。
如前所述，参考信号可以为SS/PBCH或者CSI-RS。其中，SS/PBCH波束的宽度较宽，最多64个SS/PBCH资源可以覆盖整个小区，因此在采用SS/PBCH的情况下可以对邻小区引起的干扰有一个总体的了解。另 一方面，CSI-RS的波束宽度较窄，在采用CSI-RS的情况下可以更为精确地获知邻小区引起的干扰状况。
为了完成邻小区的干扰波束的测量，服务小区需要提前为UE配置测量资源，该测量资源可以包括邻小区用于发射波束的SS/PBCH资源或者NZP CSI-RS(Non-Zero Power CSI-RS)资源，还可以包括服务小区的用于L1-RSRP测量的SS/PBCH资源或者NZP CSI-RS资源。在邻小区用于发送参考信号的资源与上报单元102所上报的用于干扰波束测量的邻小区的发送参考信号的资源一致的情况下，配置信息中可以不包括该项。
此外，与干扰波束测量有关的周期性配置可以包括如下中的一个或多个：周期性测量、非周期性测量、半静态测量。其中，干扰波束测量可以每隔预定时间周期性地执行，也可以非周期地执行，例如在通信质量下降到预定程度时执行。干扰波束测量还可以采用半静态的方式执行，比如基站通过下行控制信息(Downlink Control Information，DCI)动态地触发干扰波束的测量。应该理解，上述三种周期性配置可以结合使用。
干扰波束的扫描机制可以包括如下之一：邻小区的基站扫描发射波束，服务小区的UE扫描接收波束(下文中也称为P1’过程)；邻小区的基站扫描发射波束，服务小区的UE固定接收波束(下文中也称为P2’过程)；以及邻小区的基站固定发射波束，服务小区的UE扫描接收波束(下文中也称为P3’过程)。
为了便于理解，图3A示出了P1’过程的一个示例，图3B示出了P2’过程的一个示例，图3C示出了P3’过程的一个示例。在图3A至图3C中，小区A为服务小区，小区B为邻小区，黑色实线所表示的波束为测量所涉及的发射波束或接收波束。应该注意，图3A中用黑色实线所示出的邻小区的发射波束和图3B至图3C中用灰色实线所示出的邻小区的发射波束可能仅是邻小区所能发射的发射波束的一部分而非全部，类似地，所示出的UE的接收波束也可能仅是UE所能使用的接收波束的一部分。此外，虽然图3A至图3C中仅示出了一个邻小区，但是这并不是限制性的，而是可以存在多个邻小区。
在参考信号为SS/PBCH的情况下，资源指示符为同步信号块资源指 示符(Synchronization Signal Block Resource indicator，SSBRI)。由于SS/PBCH的周期性发送属性，因此可以采用如下配置：执行周期性的干扰波束测量，以及/或者采用P1’过程。在参考信号为CSI-RS的情况下，资源指示符为信道状态信息参考信号资源指示符(CSI-RS Resource Indicator，CRI)。为了减轻邻小区发送参考信号的负荷，在这种情况下可以采用如下配置：执行非周期的干扰波束测量；以及/或者采用P2’过程或P3’过程。应该理解，这些配置仅是示意性示例，并不是限制性的。
在参考信号为CSI-RS的情况下，执行单元103还可以被配置为基于RRC信令中的特定参数来确定干扰波束的扫描机制。例如，该特定参数为InterferenceMeasureRSRepetition，当该特定参数设置为ON时，表示参考信号的发送是重复的，因此干扰波束的扫描机制为：邻小区基站固定发射波束，服务小区的用户设备扫描接收波束，即P3’过程；当该特定参数设置为OFF时，表示参考信号的发送不是重复的，因此干扰波束的扫描机制为：邻小区基站扫描发射波束，服务小区的用户设备固定接收波束，即P2’过程。此外，当该特定参数没有被配置时，可以认为CSI-RS资源不是用于干扰波束测量的。
例如，执行单元103被配置为：针对服务小区的用于参考信号收发的每一个波束对，测量L1-RSRP；针对用于干扰波束测量的、由邻小区的基站的发射波束与服务小区的用户设备的接收波束构成的每一个波束对，测量物理层接收信号强度指示(L1-Received Signal Strength Inication，L1-RSSI)，或者测量承载参考信号的资源单元上的干扰与噪声之和；以及基于所测量的L1-RSRP和L1-RSSI计算服务小区的每一个波束对在考虑邻小区的干扰的情况下的物理层参考信号接收质量(L1-Reference Signal Receiving Quality，L1-RSRQ)，或者基于所测量的L1-RSRP和干扰与噪声之和计算服务小区的每一个波束对在考虑邻小区的干扰的情况下的物理层信干噪比(L1-Signal to Interference and Noise Ratio，L1-SINR)。下文中L1-RSRQ和L1-SINR也可被简称为RSRQ和SINR。
其中，通过测量服务小区的发射接收波束对的L1-RSRP和针对同一接收波束测量邻小区的干扰波束的L1-RSSI或干扰与噪声之和(I+N)，并取二者的比值(即，L1-RSRP/L1-RSSI或L1-RSRP/(I+N))，可以获得该波束对在考虑邻小区的干扰情况下的波束质量，即L1-RSRQ或 L1-SINR。图4示出了该测量的一个示意图。在图4中，用黑色实线的波束代表发射波束和接收波束，小区A为服务小区，小区B和C为邻小区，应该理解，邻小区的数量并不限于图中所示的2个。
在针对一个接收波束扫描邻小区的多个干扰波束，例如图4中扫描邻小区B和C的三个波束的情况下，可以获得多个L1-RSRQ或L1-SINR，例如可以根据需要保留最大值或最小值。
在一个示例中，执行单元103还可以基于所计算的L1-RSRQ或L1-SINR，确定L1-RSRQ或L1-SINR最高的服务小区的N个波束对作为在考虑邻小区的干扰的情况下的波束质量最好的N个波束对，上报单元102将该N个波束对中的发射波束对应的参考信号的资源的资源指示符作为测量结果上报至基站，其中，N为自然数。这样，基站可以获知受到邻小区的干扰较小的发射波束。其中，在采用参考信号SS/PBCH的情况下，上报的为SSBRI，在采用参考信号CSI-RS的情况下，上报的为CRI。例如，N可以等于4。
此外，上报的测量结果还可以包括与N个波束对相关联的波束质量的指示。
例如，波束质量的指示包括与N个波束对中的每一个波束对相关联的L1-RSRQ或L1-SINR的量化值。图5示出了对RSRQ进行量化的一个示例。其中，RSRQ的量化范围为-34dB至2.5dB，步长为0.5dB，因此共有77个量化状态，每个RSRQ上报值可以用7比特字段表示。此外，对于SINR可以类似地进行量化。
图6示出了在参考信号为CSI-RS的情况下所上报的测量结果的一个示意性示例。在图6中，CSI字段包括4个CRI以及分别与这四个CRI对应的RSRQ的量化值，CRI#1至CRI#4与RSRQ#1至RSRQ#4依次一一对应。CRI#1至CRI#4所对应的RSRQ例如从高到低，即，CRI#1对应的RSRQ#1的值最大。
当然，也可以采用SINR作为对CRI排序的指标，并且上报与前四个CRI对应的SINR。另外，如果参考信号为SS/PBCH，则用SSBRI来代替CRI。
注意，图6中的RSRQ除了与第一个CRI对应的值采用实际量化值表示外，其余的RSRQ均用差分值来表示，以减小信令开销。换言之， 执行单元103还可以被配置为以最高的L1-RSRQ或L1-SINR作为基准，使用N个波束对中的其他波束对相关联的L1-RSRQ或L1-SINR相对于该基准的差分值作为其他波束的波束质量的指示。
除了L1-RSRQ或L1-SINR的量化值，波束质量的指示还可以包括N个波束对中的每一个波束对的L1-RSRP是否在预定阈值以上的指示或者该L1-RSRP所在的取值范围的指示。这样例如可以指示L1-RSRQ或L1-SINR很高但是L1-RSRP很低的发射波束。
当包含每一个波束对的L1-RSRP是否在预定阈值以上的指示时，该指示例如可以通过额外的1比特字段表示。此外，可以将L1-RSRP可能的取值的值域分为几个范围，并且根据所分成的范围的个数来确定要使用的比特数。例如，将L1-RSRP可能的取值的值域分为4个范围，并且使用额外的2比特来指示L1-RSRP所在的取值范围。这里的额外的1比特或2比特字段例如可以加在RSRQ或SINR的量化值之后。
又例如，波束质量的指示包括N个波束对中的每一个波束对的L1-RSRP的量化值，其中，波束质量的指示还可以包括与N个波束对中的每一个波束对相关联的L1-RSRQ或L1-SINR的量化值，也可以不包括L1-RSRQ或L1-SINR的量化值。
为了减小信令开销，可以以最高的L1-RSRP作为基准，使用其他L1-RSRP相对于该基准的差分值作为其他波束对的L1-RSRP的量化值，波束质量的指示中还包括指示最高的L1-RSRP在测量结果中的位置的信息。这是因为，由于所上报的资源指示符是按照L1-RSRQ或L1-SINR进行排序的，因此L1-RSRQ或L1-SINR最高的资源指示符对应的波束对的L1-RSRP不一定具有最大值，换言之，作为基准的L1-RSRP不一定是第一个L1-RSRP，所以需要额外的信息来指示作为基准的L1-RSRP在测量结果中的位置。
图7示出了在参考信号为CSI-RS的情况下所上报的测量结果的另一个示意性示例。在图7中，CSI字段中包括上报的CRI#1至CRI4以及与其对应的RSRP的量化值，此外还包括指示最高的L1-RSRP的位置的2比特或更少比特。在该示例中，CRI#2对应的波束对的L1-RSRP最高，因此上述2比特用于指示例如位置2。可以理解，在上报的CRI更少的情况下，可以使用更少的比特来指示最高的L1-RSRP的位置。
此外，虽然图7中未示出，但是CSI字段中还可以包括图6中所示的RSRQ(或SINR)值。类似地，在参考信号为SS/PBCH的情况下，资源指示符为SSBRI。
在另一个示例中，执行单元103基于所测量的L1-RSRP，确定L1-RSRP最高的服务小区的N个波束对作为在考虑邻小区的干扰的情况下的波束质量最好的N个波束对，上报单元102将该N个波束对中的发射波束对应的参考信号的资源的资源指示符作为测量结果上报至基站，其中，N为自然数，并且测量结果中还包括与N个波束对相关联的干扰信息。
例如，测量结果中还包括N个波束对中的每一个波束对的L1-RSRP的量化值，其中，以最高的L1-RSRP作为基准，使用其他物理层参考信号接收功率相对于该基准的差分值作为其他波束对的L1-RSRP的量化值。图8示出了对L1-RSRP进行量化的一个示例。其中，参考信号为CSI-RS，CSI-RSRP的量化范围为-140dBm至-44dBm，步长为1dBm，因此共有98个量化状态，每个CSI-RSRP上报值可以用7比特字段表示。对于参考信号为SS/PBCH的情况，可以进行类似的量化。
与现有技术不同，该示例中上报的测量结果还包括与N个波束对相关联的干扰信息。例如，干扰信息可以为与N个波束对中的每一个波束对相关联的L1-RSRQ或L1-SINR是否在预定阈值以上的指示。可以将该指示附加到RSRP的量化值之后，该指示可以用1比特字段表示。
此外，干扰信息还可以为与N个波束对中的每一个波束对相关联的L1-RSRQ或L1-SINR所在的取值范围的指示。表示该指示所需要的比特数取决于取值范围的个数，例如，当L1-RSRQ或L1-SINR可能取值的值域被划分为四个取值范围时，则可以用2比特字段来表示该指示，类似地，该指示可以附加到RSRP的量化值之后。
或者，干扰信息可以包括指示N个波束对按照L1-RSRQ或L1-SINR排序的信息。例如，针对每一个上报的资源指示符，包含将N个波束对按照L1-RSRQ或L1-SINR从高到低排序时与该资源指示符相应的波束所对应的序号。图9示出了在参考信号为CSI-RS的情况下所上报的测量结果的另一个示意性示例。在该示例中，CSI字段包括按照RSRP由大到小排序获得的前4个波束对对应的CRI#1至CRI#4和与该四个 CRI一一对应的RSRP的量化值，其中，只有最大的RSRP用实际值的量化值表示，其他RSRP用相对于该最大RSRP的差分值表示。CSI字段还包括指示CRI#1至CRI#4的序号的2比特或更少比特，该序号是通过将CRI#1至CRI#4对应的波束对按照其L1-RSRQ或L1-SINR从高到低进行排序而获得的。
或者，干扰信息可以包括与N个波束对中的每一个波束对相关联的L1-RSRQ或L1-SINR，图10示出了在参考信号为CSI-RS的情况下所上报的测量结果的另一个示意性示例，其中，除了各个CRI的RSRP之外，还包括各个CRI的RSRQ，最大的RSRQ用其实际量化值表示且其他RSRQ用相对于该最大RSRQ的差分值来表示。并且，由于CRI#1所对应的波束对的RSRQ不一定具有最大值，因此，还包括指示最大的RSRQ所在的位置的信息。在图10的示例中，使用2比特或更少的比特来指示该位置，例如CRI#2对应的波束对的RSRQ最大。类似地，还可以用SINR来代替RSRQ，或者在参考信号为SS/PBCH的情况下使用SSBRI作为资源指示符。
在又一个示例中，执行单元103还被配置为基于L1-RSRQ或L1-SINR，确定邻小区的基站的发射波束与服务小区的用户设备的接收波束构成的波束对中对服务小区造成的干扰最强或最弱的M个波束对，并将该M个波束对中的发射波束对应的邻小区的参考信号的资源的资源指示符以及邻小区的标识包括在测量结果中。或者，执行单元103还可以被配置为基于针对邻小区的发射波束的L1-RSRP，确定邻小区的发射波束中对服务小区造成的干扰最强或最弱的M个波束，并将该M个波束对应的邻小区的参考信号的资源的资源指示符以及邻小区的标识包括在测量结果中。例如，为了确定针对邻小区的每一个发射波束的最大L1-RSRP，UE可以尝试使用不同的接收波束。
该测量结果能够告知服务小区的基站使用哪些发射波束将受到邻小区的最强干扰，或者使用哪些发射波束可以尽可能避免受到邻小区的干扰。此外，由于UE报告了邻小区的波束产生的干扰情况，因此邻小区和服务小区之间可以执行波束级别的系统调度。比如，当邻小区使用了对UE产生强干扰的下行发射波束时，服务小区可以使得UE尽量避免使用接收到邻小区该强干扰的接收波束。
图11示出了在参考信号为CSI-RS的情况下所上报的测量结果的另 一个示意性示例。在该示例中，CSI字段包括邻小区引起的干扰最强的M个(比如M＝4)波束对应的CRI以及相应的邻小区的物理小区标识(Physical cell ID，PCI)。此外，CSI字段中还包括与这M个波束分别对应的RSRP的量化值。在M个波束是基于L1-RSRP确定的情况下，RSRP的量化值为分别针对M个(比如M＝4)波束中的每一个所能获得的最大RSRP，类似地，最大的RSRP用其实际量化值表示且其他RSRP用相对于该最大RSRP的差分值来表示。另一方面，在M个波束是基于L1-RSRQ或L1-SINR确定的情况下，RSRP的量化值为在采用对应的M个(比如M＝4)波束对的情况下，UE接收到的邻小区的发射波束的RSRP的量化值，类似地，最大的RSRP用其实际量化值表示且其他RSRP用相对于该最大RSRP的差分值来表示。但是，在后一种情形下，L1-RSRQ或L1-SINR最大的发射波束对应的RSRP不一定最高，因此，CSI字段中还可以包括指示最高的RSRP所在的位置的信息，如图11中的斜体字一栏所示，例如使用2比特或更少的比特来指示该信息。
图12示出了在参考信号为CSI-RS的情况下所上报的测量结果的另一个示意性示例。与图11不同，在该示例中，CSI字段包括邻小区引起的干扰最弱的4个波束对应的CRI以及相应的邻小区的PCI。类似地，该CRI可以是基于L1-RSRQ或L1-SINR选择的，也可以是基于L1-RSRP选择的。参照图11所进行的说明类似地适用于图12，在此不再重复。
另外，在参考信号为SS/PBCH的情况下，所上报的资源指示符为SSBRI。应该理解，在采用过程P3’的情况下，由于邻小区的发射波束固定，因此不必要进行如图11或图12所示的上报。
以上虽然描述了上报的测量结果的多个示例，但是应该理解，这种描述并不是限制性的，还可以采用其他各种上报形式。
此外，除了用于波束管理的参考信号测量之外，UE还执行用于移动性管理的参考信号测量。用于移动性管理的参考信号的资源具有比用于波束管理的参考信号的资源更长的周期。如果两种资源是空间准共址(Quasi Co-located，QCLed)的，则在某些时刻UE可以测量这两种资源以获得更准确的结果，这称为联合测量。图13示出了用于波束管理的参考信号的资源和用于移动性管理的参考信号的资源之间的关系的示意图。可以看出，在虚线框处，这两种资源是空间准共址的，UE可以对两 种资源进行测量并作为本申请的测量结果来上报。
相应地，上报单元102可以被配置为将指示是否支持联合测量的信息上报至基站，其中，如上所述，联合测量包括同时测量用于干扰波束测量的参考信号的资源以及测量空间准共址的用于移动性测量的资源。
综上所述，根据本实施例的电子设备100通过执行干扰波束测量来测量邻小区的发射波束对服务小区的干扰程度，从而能够在考虑干扰的情况下更加准确地评估服务小区的各个波束的波束质量，进而实现更高效的波束管理。
<第二实施例>
图14示出了根据本申请的另一个实施例的电子设备200的功能模块框图，如图14所示，电子设备200包括：获取单元201，被配置为获取来自服务小区的用户设备的待测资源指示符，该待测资源指示符指示期望被用于干扰波束测量的邻小区的发送参考信号的资源，该干扰波束测量用于测量邻小区的发射波束对服务小区的干扰程度；提供单元202，被配置为将该待测资源指示符提供给邻小区的基站；以及生成单元203，被配置为生成用于所述干扰波束测量的配置信息，以提供给用户设备。
其中，获取单元201、提供单元202和生成单元203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、处理器。并且，应该理解，图14中所示的电子设备中的各个功能单元仅是根据其所实现的具体功能而划分的逻辑模块，而不是用于限制具体的实现方式。这同样适用于随后要描述的其他电子设备的示例。
电子设备200例如可以设置在基站侧或者可通信地连接到基站。本申请中所述的基站也可以是收发点(Transmit Receive Point，TRP)或者接入点(Access Point,AP)。这里，还应指出，电子设备200可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备200可以工作为基站本身，并且还可以包括诸如存储器、收发器(未示出)等外部设备。存储器可以用于存储基站实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，用户设备、其他基站等等)间的通信，这里不具体限制收发器的实现形式。这同样适用于随后关于基站侧的电子设备其他配置示例的描述。
有关干扰波束测量的详细描述可以参见第一实施例中所述，在此不再重复。例如，要用于干扰波束测量的参考信号可以为SS/PBCH或者CSI-RS。相应地，获取单元201所获取的待测资源指示符可以分别为SSBRI和CRI。这些待测资源指示符实质上指示了邻小区的发射波束的方向。如第一实施例中所述，这些待测资源指示符例如可以由UE根据其初始接入时收集的信息以及/或者移动性相关的配置来确定。
接着，提供单元202例如可以通过Xn信令将待测资源指示符提供给邻小区的基站。在一个示例中，邻小区将提供与该待测资源指示符对应的发射波束，而不向服务小区的基站发送任何反馈。
在另一个示例中，邻小区的基站还根据自身的资源使用状况等判断能否提供待测资源指示符所指示的资源，即判断能否为服务小区提供相应的发射波束，并将该判断结果通过反馈的形式提供给服务小区的基站。在这种情况下，获取单元201还被配置为从邻小区的基站获取针对待测资源指示符的反馈信息。
反馈信息例如可以包括如下之一：确认信息；经修改的待测资源指示符。例如，在参考信号为CSI-RS的情况下，邻小区的基站可以判断当前的CSI-RS资源是否充足，如果充足，则可以向服务小区的基站发送确认信息，表示将按照待测资源指示符来提供发射波束，否则，可以根据当前资源占用状况确定能够提供的资源，并将经修改的待测资源指示符提供给服务小区的基站。该反馈信息也通过Xn信令来进行传输。
相应地，当邻小区要执行干扰波束测量时，获取单元201还被配置为接收来自邻小区的基站的待测资源指示符。此外，获取单元201还可以向邻小区的基站提供对于接收的待测资源指示符的反馈信息。
另一方面，如果邻小区的基站对待测资源指示符进行了修改，则服务小区的基站还将经修改的待测资源指示符的信息提供给UE，以使得UE进行正确的测量。该信息可以包含在以下将要描述的配置信息中。
生成单元203生成用于干扰波束测量的配置信息，以提供给UE。例如，配置信息可以包括如下中的一个或多个：服务小区的用于干扰波束测量的资源；邻小区的发送参考信号的资源；与干扰波束测量有关的周期性配置；干扰波束的扫描机制；参考信号的类别。
这些配置信息例如可以经由RRC信令提供给UE。并且，这些配置 信息可以经由一条或多条RRC信令来提供。有关配置信息中各项的详细说明已经在第一实施例中给出，在此不再重复。
其中，与干扰波束测量有关的周期性配置包括如下中的一个或多个：周期性测量，非周期性测量，半静态测量。干扰波束的扫描机制包括如下之一：邻小区基站扫描发射波束，服务小区的UE扫描接收波束；邻小区基站扫描发射波束，服务小区的UE固定接收波束；以及邻小区基站固定发射波束，服务小区的UE扫描接收波束，如第一实施例中参照图3A至3C所述。基站根据这些配置相应地为UE分配测量资源。
例如，生成单元203可以被配置为基于RRC信令中的特定参数来向UE指示干扰波束的扫描机制。该特定参数例如为InterferenceMeasureRSRepetition，当该特定参数设置为ON时，邻小区的干扰波束的扫描机制为：邻小区基站固定发射波束，服务小区的用户设备扫描接收波束；当该特定参数设置为OFF时，邻小区的干扰波束的扫描机制为：邻小区基站扫描发射波束，服务小区的用户设备固定接收波束。
此外，获取单元201还被配置为从UE获取干扰波束测量的测量结果。例如，测量结果包括服务小区的用于发送参考信号的N个资源的资源指示符，其中，在用于干扰波束测量的波束对中，与该N个资源对应的发射波束和用户设备的接收波束构成的N个波束对具有在考虑邻小区的干扰的情况下的最好的波束质量，其中N为自然数。测量结果还可以包括与N个波束对相关联的波束质量的指示。
在一个示例中，在用于干扰波束测量的波束对中，这N个波束对具有最高的L1-RSRQ或L1-SINR。波束质量的指示可以包括与N个波束对中的每一个波束对的相关联的L1-RSRQ或L1-SINR的量化值。此外，波束质量的指示还包括N个波束对中的每一个波束对的L1-RSRP是否在预定阈值以上的指示或者该L1-RSRP所在的取值范围的指示。
在另一个示例中，在用于干扰波束测量的波束对中，这N个波束对具有最高的L1-RSRP，并且波束质量的指示中包括与这N个波束对相关联的干扰信息。例如，干扰信息可以包括如下中的一个：与N个波束对中的每一个波束对相关联的L1-RSRQ或L1-SINR是否在预定阈值以上的指示；与所述N个波束对中的每一个波束对相关联的L1-RSRQ或 L1-SINR所在的取值范围的指示；指示所述N个波束对按照L1-RSRQ或L1-SINR的排序的信息。此外，波束质量的指示中还可以包括与这N个波束对相对应的L1-RSRP的量化值。
在又一个示例中，测量结果可以包括对服务小区造成的干扰最强或最弱的邻小区的M个发射波束所对应的参考信号的资源的资源指示符以及邻小区的标识。
以上所述的测量结果的具体形式和内容可以结合使用，其细节在第一实施例中参照图5至图13给出，在此不再重复。
此外，获取单元201还被配置为指示是否支持联合测量的信息，其中，联合测量包括同时测量用于干扰波束测量的参考信号的资源以及测量空间准共址的用于移动性测量的资源。通过联合测量，可以提高干扰波束测量的准确性。
综上所述，根据本申请的电子设备200能够通过UE执行的干扰波束测量来获知邻小区的发射波束对服务小区的干扰程度，从而能够在考虑干扰的情况下更加准确地评估服务小区的各个波束的波束质量，进而实现更高效的波束管理。
<第三实施例>
在上文的实施方式中描述用于无线通信的电子设备的过程中，显然还公开了一些处理或方法。下文中，在不重复上文中已经讨论的一些细节的情况下给出这些方法的概要，但是应当注意，虽然这些方法在描述用于无线通信的电子设备的过程中公开，但是这些方法不一定采用所描述的那些部件或不一定由那些部件执行。例如，用于无线通信的电子设备的实施方式可以部分地或完全地使用硬件和/或固件来实现，而下面讨论的用于无线通信的方法可以完全由计算机可执行的程序来实现，尽管这些方法也可以采用用于无线通信的电子设备的硬件和/或固件。
