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>
图1a示出了相邻的小区1、小区2和小区3的CSI-RS配置的时频资源分配的示意图。在本文中，CSI-RS配置可以指为CSI-RS所分配的时频资源的位置。在图1a中，每个小区的CSI-RS配置包括8个端口(用序号0-7表示)，每一个端口对应于一个时频资源单元，即，图1a中的每个CSI-RS配置对应于8个时频资源单元(Resource Element，RE)， 每个RE上的数字代表对应的CSI-RS端口的序号。应该注意，这里的序号只是代表性的数字，并不是实际的端口号，例如在实际的8端口CSI-RS配置中，使用的端口为15-22。具体地，小区1的CSI-RS配置的各个端口对应于灰色填充的RE，小区2的CSI-RS配置的各个端口对应于黑点填充的RE，小区3的CSI-RS配置的各个端口对应于横线填充的RE。对于每一个小区而言，在其他小区的CSI-RS配置对应的RE上不发送任何信息，图中用斜线填充相应的框来表示这一点。
当小区使用波束赋形CSI-RS方案时，小区并不会一直使用CSI-RS配置中的所有的CSI-RS端口。换言之，某些CSI-RS端口对应的时频资源被闲置，从而造成了资源的严重浪费。以Cell-Specific波束赋形为例，在一个子帧内活跃波束的数量通常少于配置的波束数量，而当配置使用的是非周期CSI-RS时，资源的浪费将更加严重。注意，在本说明书中，如无特别说明，小区可以是宏小区和小小区，并且在适当情况下，小区也被称为基站。此外，在本说明书中，CSI-RS端口对应的时频资源被简称为CSI-RS资源、CSI-RS端口或者资源。
图2示出了波束赋形CSI-RS方案下的资源浪费的一个示意图。其中，基站1、基站2和基站3使用不同的CSI-RS配置来避免小区间CSI-RS干扰。假设一个CSI-RS配置包括8个CSI-RS端口，一个波束使用2个CSI-RS端口形成，实心波束表示波束处于服务状态、即激活状态，空心波束表示波束处于空闲状态。例如，基站2中有2个波束处于激活状态，2个波束处于空闲状态，因此有4个CSI-RS时频资源单元(以下也简称为CSI-RS资源)未被使用。类似地，基站3中有4个CSI-RS资源未被使用。在一个基站有多个相邻基站的情况下，资源浪费现象将会更加严重。
如果基站1要服务的用户设备很多，使用相邻基站未使用的CSI-RS的时频资源用来进行数据传输将非常有意义。本申请的技术提供了利用空闲CSI-RS资源来进行数据传输的实现。
此外，除了相邻基站未使用的CSI-RS的时频资源之外，基站1也可以利用其自身的CSI-RS的空闲时频资源。但是，在下文中将主要讨论基站利用相邻基站的CSI-RS配置的空闲的时频资源的情形，应该理解，这并不是限制性的，不能理解为本发明对利用或者不利用自身的 CSI-RS配置的空闲时频资源作出了任何规定或者限制。
另一方面，虽然在图2的示例中，相邻小区(或基站)使用不同的CSI-RS配置，但是相邻小区也可以使用相同的CSI-RS配置并通过其他技术手段来减轻或消除CSI-RS干扰，而这并不影响本申请的技术的应用。由于对于要利用空闲CSI-RS资源进行数据传输的小区而言，要利用的是哪一个小区空闲的CSI-RS资源并不重要，该小区只需要获知该空闲的CSI-RS资源的位置即可。同时，由于CSI-RS配置是有固定模式并且有有限的数量，因此，可以以CSI-RS配置为单位识别空闲的CSI-RS资源。
图3示出了根据本申请的一个实施例的电子设备100的功能模块框图，该电子设备100包括：允许单元101，被配置为允许一个小区使用与该一个小区的自身CSI-RS配置不同的CSI-RS配置的空闲的CSI-RS端口对应的时频资源的至少一部分进行数据传输。在下文中，也将针对其执行操作的“所述一个小区”称为本小区。
该电子设备100例如可以位于小区的基站侧，或者与基站通信地耦接，该耦接可以是有线的或者无线的。
由于对于一个小区而言，其使用的CSI-RS配置是已知的，因此，与本小区的自身CSI-RS配置不同的CSI-RS配置(以下也称为其他CSI-RS配置)也是能够获知的，而这些其他CSI-RS配置的空闲的CSI-RS端口对应的时频资源可以由本小区用来进行数据传输。其中，本小区可以使用所有的空闲的CSI-RS资源来进行数据传输，也可以仅使用其中的一部分，取决于实际的需要或配置。
此外，如前所述，本小区也可以使用自身的空闲CSI-RS资源进行数据传输。在这种情况下，允许单元101被配置为允许本小区使用所有CSI-RS配置的空闲的CSI-RS端口对应的时频资源的至少一部分进行数据传输。
另一方面，小区对空闲的CSI-RS资源的使用并不限于以上方式，例如，允许单元101可以使得小区直接使用上述时频资源。换言之，可以设置为：小区使用其认为空闲(或者预先规定)的CSI-RS资源进行数据传输(这里所述的空闲的CSI-RS资源可以包括本小区的CSI-RS配 置的空闲CSI-RS资源，也可以不包括)。随后，在获得了实际的关于CSI-RS空闲资源的信息后，根据该信息来调整或停止其对空闲的CSI-RS资源的使用。例如，在用于进行数据传输的CSI-RS资源实际上正被使用的情况下，将停止使用该时频资源来进行数据传输。
在一个示例中，实际的关于CSI-RS空闲资源的信息来自于相邻小区。如图3中的虚线框所示，电子设备100还包括：确定单元102，被配置为确定本小区的相邻小区的CSI-RS的端口使用情况，并基于该端口使用情况确定各个CSI-RS配置的空闲CSI-RS端口对应的时频资源。
其中，相邻小区可以为处于本小区的干扰范围内的小区，或者，相邻小区为本小区在地理位置上相邻的小区。对于一个小区而言，如果其干扰范围内没有任何其他小区，则理论上该小区可以使用不同于其自身CSI-RS配置的任何CSI-RS配置对应的时频资源进行数据传输。但是，由于其干扰范围内通常总是有其他小区的，因此，需要避免对这些小区的CSI-RS传输的干扰，即，仅使用这些小区的CSI-RS配置的空闲CSI-RS端口对应的时频资源进行数据传输。
在无线通信系统中，CSI-RS配置的种类数是有限的，例如，在每一个CSI-RS配置包括8个CSI-RS端口的情况下，共有5种CSI-RS配置。而在为各个小区分配CSI-RS配置时，一般尽量为相邻小区分配不同的CSI-RS配置以避免CSI-RS干扰。因此，通过统计所有相邻小区的CSI-RS的端口使用情况，一般可以获得各个CSI-RS配置的CSI-RS端口的空闲状况。该空闲状况例如包括该CSI-RS配置中哪些CSI-RS端口处于空闲状态的信息。在一个示例中，对于由两个或多个相邻小区使用的CSI-RS配置，将具有最少的CSI-RS空闲端口的相邻小区的CSI-RS配置的空闲CSI-RS端口对应的时频资源的数量作为该CSI-RS配置的空闲CSI-RS端口对应的时频资源的数量。换言之，在CSI-RS配置的空闲CSI-RS端口数量在多个相邻小区中具有多个取值时，取其中的最小值作为该CSI-RS配置的空闲CSI-RS端口数量。
以图1a中所示的CSI-RS配置为例，在小区1要服务的用户设备很多从而期望使用相邻小区未使用的CSI-RS的时频资源用来进行数据传输的情况下，确定单元102确定小区2的CSI-RS端口4-7空闲，小区3的CSI-RS端口4-7空闲，即小区2和3实际上没有利用其CSI-RS配置 的CSI-RS端口4-7对应的时频资源传输CSI-RS。因此，小区1可以使用与这些空闲CSI-RS端口对应的时频资源进行数据传输。如图1b所示，代替用斜线填充，可以用网格来填充这些RE，表示小区1使用这些空闲CSI-RS资源单元来进行数据传输。应该理解，图1b仅是一个示例，对于其他小区而言，可以进行类似的操作。并且，图1a和图1b中仅示出了常规循环前缀(CP)的OFDM子帧作为示例，但是本技术同样可以应用于采用其他类型的OFDM子帧的情形。
在一个示例中，确定单元102可以被配置为根据来自相邻小区的基站的X2信令来获得该相邻小区的CSI-RS端口的使用情况。
例如，X2信令可以为ENB CONFIGURATION UPDATE消息，该ENB CONFIGURATION UPDATE中包括指示该相邻小区的CSI-RS配置中的各个CSI-RS端口的使用状况的信息的信息单元。示例性地，该信息单元可以包括在ENB CONFIGURATION UPDATE消息的信息单元Served Cell Information中，例如在该信息单元中添加新的信息单元Antenna_ports_usage。
例如，该信息单元可以具有位图的形式，位图的比特数根据CSI-RS配置的CSI-RS端口数确定。在CSI-RS配置具有8个CSI-RS端口的情况下，位图可以有8个比特。位图的一个比特为0可以表示相应CSI-RS端口未被使用，位图的一个比特为1表示相应CSI-RS端口正被使用。当然，也可以采用相反的定义。
在另一个示例中，确定单元102可以根据来自中央处理装置的消息获取相邻小区的CSI-RS端口的使用情况。在该示例中，例如设置中央处理装置来收集各个小区的CSI-RS配置的CSI-RS端口的使用情况，并向各个小区提供其相邻小区的CSI-RS配置的CSI-RS端口的使用情况。中央处理装置可以与各个小区的基站通过有线或无线方式通信地耦接。中央处理装置例如可以位于核心网侧或服务器上。
或者，中央处理装置可以对收集的各个小区的CSI-RS配置的CSI-RS端口的使用情况进行更进一步的处理，例如针对一个小区获得各个CSI-RS配置的空闲CSI-RS端口对应的时频资源的信息或者除该小区的CSI-RS配置之外的其他CSI-RS配置的空闲CSI-RS端口对应的时频资源的信息，并将这些信息提供给相应的小区。在这种情况下，确定单 元102可以直接从来自中央处理装置的消息确定各个CSI-RS配置的空闲CSI-RS端口对应的时频资源。
此外，中央处理装置也可以进行进一步处理以针对一个小区获得该小区能够用于进行数据传输的其他CSI-RS配置(或各个CSI-RS配置)的空闲CSI-RS端口对应的时频资源的信息，并将这些信息提供给相应的小区。在这种情况下，确定单元102可以直接从来自中央处理装置的消息确定能够用于进行数据传输的各个CSI-RS配置的空闲CSI-RS端口对应的时频资源。
该电子设备100中的各个单元例如可以通过一个或多个处理电路来实现，该处理电路例如可以实现为芯片。
在本实施例中，电子设备100通过使得小区能够利用其他CSI-RS配置的空闲的CSI-RS端口对应的时频资源进行数据传输，提高了CSI-RS的资源利用效率。
<第二实施例>
如前所述，允许单元101可以基于确定单元102的确定结果来执行操作，也可以基于确定单元102的确定结果来决定是否继续之前的操作或对之前的操作进行相应的改变。
在一个示例中，允许单元101不进行任何判断而允许小区使用其他CSI-RS配置的空闲CSI-RS端口对应的时频资源。或者，允许单元101根据特定条件来允许或禁止小区对其他CSI-RS配置的空闲CSI-RS端口对应的时频资源的使用，下面将参照图4进行描述。
图4示出了根据本申请的一个实施例的电子设备200的功能模块框图，除了图3所示的各个单元之外，电子设备200还包括：判断单元201，被配置为判断空闲CSI-RS端口对应的时频资源是否满足第一预定条件；并且在满足第一预定条件的情况下，允许单元101允许本小区使用空闲的CSI-RS端口对应的时频资源的至少一部分进行数据传输。
类似地，该电子设备200中的各个单元例如可以通过一个或多个处理电路来实现，该处理电路例如可以实现为芯片。该电子设备200例如 可以位于小区的基站侧，或者与基站以有线或无线方式通信地耦接。
例如，可以仅在空闲CSI-RS资源较多的情况下才允许小区使用空闲CSI-RS资源的一部分或全部进行数据传输。示例性地，第一预定条件为至少一部分CSI-RS配置的、能够由本小区使用的空闲CSI-RS端口对应的时频资源的数量之和超过第一预定阈值。
在一个示例中，第一预定条件为不同于本小区的自身CSI-RS配置的所有CSI-RS配置的所有空闲CSI-RS端口对应的时频资源的数量之和超过第一预定阈值，例如用下式表示：
Figure PCTCN2017077632-appb-000001
其中，Ri表示CSI-RS配置i的空闲资源数量，Th1为第一预定阈值，其中Th1例如取决于信令比特的消耗、利用空闲CSI-RS资源传输数据所提高的数据吞吐量、期望的最高数据吞吐量提升比例等因素。
在另一个示例中，至少一部分CSI-RS配置可以包括其空闲CSI-RS端口的数量超过预定值的CSI-RS配置，称为空闲CSI-RS配置。在本实施例中，能够由本小区使用的空闲CSI-RS端口被限定为非本小区CSI-RS配置的空闲CSI-RS端口。因此，这里的空闲CSI-RS配置指的是满足上述空闲CSI-RS端口数量限定的、非本小区CSI-RS配置的CSI-RS配置。在这种情况下，第一预定条件可以用下式(2)来表示。
Figure PCTCN2017077632-appb-000002
此外，还可以设置为仅允许使用空闲CSI-RS配置的空闲CSI-RS端口对应的时频资源的一部分。例如，每一个空闲CSI-RS配置能够由本小区使用的空闲CSI-RS端口对应的时频资源的数量为小于或等于预定值的固定值。在这种情况下，上述数量之和为空闲CSI-RS配置的数量与固定值的乘积。第一预定条件可以用下式(3)来表示。
Figure PCTCN2017077632-appb-000003
其中，Ci表示空闲CSI-RS配置i的能够被利用的资源的数量，对于每一个空闲CSI-RS配置而言，该值均为C，N为空闲CSI-RS配置的数量。
此外，判断单元201还可以被配置为判断空闲CSI-RS端口对应的时频资源是否满足第二预定条件，并且在满足第二预定条件的情况下，允许单元101禁止本小区使用空闲的CSI-RS端口对应的时频资源进行数据传输。
或者，判断单元201可以被配置为在本小区使用空闲的CSI-RS端口的时频资源进行数据传输期间，判断空闲CSI-RS端口对应的时频资源是否满足第二预定条件，并且在满足第二预定条件的情况下，允许单元101禁止本小区使用空闲的CSI-RS端口对应的时频资源进行数据传输。
例如，在空闲CSI-RS资源较少的情况下禁止小区使用空闲CSI-RS资源进行数据传输。示例性地，第二预定条件为至少一部分CSI-RS配置的、能够由本小区使用的空闲CSI-RS端口对应的时频资源的数量之和低于第二预定阈值。其中，时频资源的数量之和的计算方式可以采用以上所述的各种方式之一，并且可以与进行第一预定条件的判断时的计算方式相同，也可以不同，这并不是限制性的，而是可以取决于实际的应用情况来选择。
第二预定阈值例如取决于信令比特的消耗、利用空闲CSI-RS资源传输数据所提高的数据吞吐量、期望的最小数据吞吐量提升比例等因素。第二预定阈值可以小于第一预定阈值。
此外，在本小区使用空闲的CSI-RS端口的时频资源进行数据传输期间，确定单元102还可以被配置为周期性地更新CSI-RS配置的CSI-RS端口的使用情况。这是因为，各个小区中CSI-RS端口的使用情况是实时变化的，周期性地更新该使用状况能够更准确地获得CSI-RS端口的空闲状态。这样，相应地调整用于数据传输的空闲的CSI-RS端口的时频资源将有助于进一步减轻对相邻小区的CSI-RS的传输的干扰。
应该注意，相邻小区对于分配给它的CSI-RS配置的各个CSI-RS端口的使用是不受本申请的技术的影响的，即，相邻小区可以使用其CSI-RS配置的任何CSI-RS端口，而不管该CSI-RS端口是否正在被其他小区用于数据传输。在一个小区利用相邻小区的空闲CSI-RS资源传输数据时，如果该相邻小区开始使用该空闲CSI-RS资源传输CSI-RS，则由于处理的延迟，可能在一定时间范围内会对本小区当前的数据传输 产生干扰，但是由于受到干扰的数据传输的资源单元仅占一小部分，因此这种干扰在可接受的范围内。随后，在本小区检测到所使用的CSI-RS资源不再空闲后，可以停止使用CSI-RS资源来传输数据或者使用其他相邻小区的空闲CSI-RS资源来继续传输数据。
在本实施例中，通过按照特定条件来使用空闲的CSI-RS资源进行数据传输，可以优化空闲的CSI-RS资源的利用，提高CSI-RS资源的利用效率。
<第三实施例>
图5示出了根据本申请的另一个实施例的电子设备300的功能模块框图，除了图3中所示的允许单元101之外，电子设备300还包括：消息生成单元301，被配置为生成用于向本小区的用户设备指示能够使用的空闲CSI-RS端口对应的时频资源的指示消息。此外，虽然图5中未示出，但是电子设备300还可以包括前文所述的确定单元102、判断单元201中的任意一个。
类似地，该电子设备300中的各个单元例如可以通过一个或多个处理电路来实现，该处理电路例如可以实现为芯片。该电子设备300例如可以位于小区的基站侧，或者与基站以有线或无线方式通信地耦接。
在一个示例中，该指示消息包括各个CSI-RS配置的、用户设备能够使用的空闲CSI-RS端口对应的时频资源的数量的信息。由于基站和用户设备之间对于CSI-RS的端口的使用的规则的理解是一致的，例如用户设备已知要优先使用哪些CSI-RS端口，比如按照固定顺序使用CSI-RS配置的情况下，例如仅需要使用4个端口时，可以首先使用端口0-3。因此，用户设备在获知能够使用的空闲CSI-RS端口对应的时频资源的数量的信息后，即可确定要使用的时频资源单元的位置，从而使用这些时频资源进行数据传输。
其中，用户设备能够使用的空闲CSI-RS端口对应的时频资源可以为所有的空闲CSI-RS资源，也可以仅为其中的一部分，这可以例如由确定单元102根据实际需要或预先规定等确定。例如，可以以与进行第一预定条件的判断时相同的方式来确定用户设备能够使用的空闲 CSI-RS资源。
指示消息的格式可以有多种形式。图6至图9示出了指示消息的形式的示例。图6示出了一种较为完整的指示消息的示例，其中，指示消息包括各个CSI-RS配置是否有能够使用的空闲CSI-RS端口的位图信息，即图中的前X比特。位图的相应比特为0表示相应CSI-RS配置的空闲CSI-RS不可用或者无空闲CSI-RS。此外，在X比特之后，分别用Y比特来表示每一个CSI-RS配置的能够使用的空闲CSI-RS端口对应的时频资源的数量。可以使相应数量为0来表示相应CSI-RS配置的空闲CSI-RS不可用或者无空闲CSI-RS。
其中，位图的比特数由CSI-RS配置的总数确定，比如，在共有5种CSI-RS配置的情况下，位图的比特数X为5。Y的取值由最大允许使用的资源的数量来决定，例如，在CSI-RS配置包括8个端口的情况下，Y取值最大为3就足以表示各种数量情况。
图7示出了一种简化的形式，其中，省略了在前的X个比特。在图7的示例中，假定事先约定了CSI-RS配置的排列顺序，换言之，用户设备已知第一个Y比特对应于哪一个CSI-RS配置，第二个Y比特对应于哪一个CSI-RS配置，以此类推。在这种情况下，对于本小区采用的CSI-RS配置，可以将其可用CSI-RS资源数设置为0(即将其对应的Y比特均设置为0)。
图8示出了另一种简化的形式，其中，X比特后只有一个Y比特。在该示例中，用户设备能够使用的各个CSI-RS配置的空闲CSI-RS端口对应的时频资源的数量是相同的。因此，只需要一个Y比特来表示该数量的信息。X比特仍然用于表示各个CSI-RS配置是否有能够使用的空闲CSI-RS端口的位图信息。
图9示出了对图8的进一步简化的形式，其中，仅包括表示各个CSI-RS配置是否有能够使用的空闲CSI-RS端口的位图信息。在这种情况下，可以事先规定好用户设备将要使用的各个CSI-RS配置的资源的数量，即，该数量对于每个CSI-RS配置而言是固定的。对于不同的CSI-RS配置，该固定数量可以是相同的，也可以是不同的。因此，只需要通知用户设备哪个CSI-RS配置的空闲资源可用即可，而无需后面的指示具体数量的信息比特。
应该理解，以上仅是指示消息的示例，但是其形式并不限于此。此外，还可以设置更为简化的形式，例如仅用1比特来指示，当该1比特为0时，没有任何一个CSI-RS配置的空闲端口可用，当该1比特为1时，对于每一种CSI-RS配置(可以包括本小区采用的CSI-RS配置、也可以不包括本小区采用的CSI-RS配置)，均可以使用事先规定好的固定数量的CSI-RS资源用于数据传输，该固定数量对于每一种CSI-RS配置可以相同也可以不同。或者，用一个Y比特来表示预先确定好的若干CSI-RS配置的要使用的资源数量(对所有配置相同)。
此外，消息生成单元301还被配置为生成用于向一个小区的用户设备指示禁止使用空闲CSI-RS端口对应的时频资源的禁止消息。在一个示例中，该禁止消息具有与上述指示消息相同的形式，只是将位图的各个比特设置为表示各个CSI-RS配置均没有可供使用的空闲资源，以及/或者将表示资源数量的比特均设置为0。在另一个示例中，可以将禁止消息生成为1比特的指令。即用户设备收到该指令后即获知被禁止使用空闲的CSI-RS资源。该方式可以有效地降低信令开销。
<第四实施例>
图10示出了根据本申请的一个实施例的信息处理设备400的功能模块框图。该信息处理设备400例如可以为基站或基站的一部分。收发单元401例如可以使用天线或通信接口实现，确定单元402、允许单元403、判断单元404例如可以通过一个或多个处理电路来实现，该处理电路例如可以实现为芯片。
在一个示例中，该信息处理设备400包括收发单元401、确定单元402和允许单元403。收发单元401可以被配置为从一个小区的相邻小区的基站接收包含该相邻小区的CSI-RS的端口使用情况的信息，其中，相邻小区为处于本小区的干扰范围内的小区。此外，确定单元402被配置为基于所接收的信息确定相邻小区的CSI-RS的端口使用情况，并基于该端口使用情况确定各个CSI-RS配置的空闲CSI-RS端口对应的时频资源，允许单元403被配置为允许一个小区使用与其CSI-RS配置不同的CSI-RS配置的空闲的CSI-RS端口对应的时频资源的至少一部分进行数据传输。本实施例中的确定单元402具有与确定单元102类似的功能， 并且允许单元403具有与允许单元101类似的功能，因此在本实施例的描述中省略了相关的细节。
在该示例中，信息处理设备400还可以包括：判断单元404，被配置为判断空闲CSI-RS端口对应的时频资源是否满足第一预定条件；并且在满足第一预定条件的情况下，允许单元403允许本小区使用空闲的CSI-RS端口对应的时频资源的至少一部分进行数据传输。判断单元404具有与判断单元201类似的功能，在此不再重复描述。
在该示例中，收发单元401还被配置为向相邻小区的基站发送包含本小区的CSI-RS的端口使用情况的信息。即，相邻小区的基站之间通过例如X2信令来交互有关CSI-RS的端口使用情况的信息。例如，该信息包含在ENB CONFIGURATION UPDATE消息的信息单元Served Cell Information中。关于该信息的具体配置可以参照第一实施例所述，在此不再重复。
在另一个示例中，收发单元401可以被配置为从中央管理装置接收包含小区的相邻小区的CSI-RS的端口使用情况的信息。在该示例中，相邻小区的基站之间不直接进行该信息的交互，而是通过中央管理装置来对该信息进行集中管理和提供。
在又一个示例中，收发单元401可以被配置为从中央管理装置接收与本小区的CSI-RS配置不同的其他CSI-RS配置的空闲CSI-RS端口对应的时频资源的信息，比如时频资源的数量。在该示例中，将由中央管理装置来执行确定单元402的功能，并将确定单元402的确定结果提供给本小区。此时，信息处理设备400可以包括收发单元401、允许单元403和判断单元404。或者，信息处理设备400可以仅包括收发单元401和允许单元403。
在另一个示例中，收发单元401可以被配置为从中央管理装置接收能够由本小区使用的各个CSI-RS配置的空闲CSI-RS端口。在该示例中，将由中央管理装置来执行确定单元402的功能以及判断单元404的功能，并将最终确定的结果提供给本小区。此时，信息处理设备400可以包括收发单元401和允许单元403。
此外，在本实施例中，收发单元401还被配置为向本小区的用户设 备发送指示能够使用的空闲CSI-RS端口对应的时频资源的指示消息。收发单元401还可以向本小区的用户设备发送指示禁止使用空闲CSI-RS端口对应的时频资源的禁止消息，其中，该禁止消息可以是取特定值的指示消息，也可以是专用的禁止消息，如第三实施例中所述。
根据本实施例的信息处理设备能够使得本小区使用其他CSI-RS配置的空闲CSI-RS资源进行数据传输，提高了CSI-RS资源的利用效率。
<第五实施例>
图11示出了根据本申请的一个实施例的电子设备500的功能模块框图，该电子设备500包括：确定单元501，被配置为基于从基站接收的消息确定用户设备能够用来进行数据传输的与所述基站使用的自身CSI-RS配置不同的CSI-RS配置的空闲的CSI-RS端口对应的时频资源；以及反馈生成单元502，被配置为生成包含用户设备反馈的消息。
该电子设备500中的各个单元例如可以通过一个或多个处理电路来实现，该处理电路例如可以实现为芯片。该电子设备500例如可以位于小区的用户设备侧，或者与用户设备以有线或无线方式通信地耦接。
从基站接收到的消息例如为前文所述的包含各个CSI-RS配置的、用户设备能够使用的空闲CSI-RS端口对应的时频资源的数量的信息的指示消息。应该理解，所接收到的消息并不限于此，只要其中包含用户设备能够用于进行数据传输的空闲的CSI-RS端口对应的时频资源的信息即可。
此外，接收的消息还可以为禁止消息，在这种情况下或者在确定的时频资源的数量为0(在广义上也属于禁止消息的一种)的情况下，用户设备被禁止使用空闲的CSI-RS端口对应的时频资源进行数据传输。
无论所接收的消息的内容为何，反馈生成单元502均要生成包含用户设备反馈的消息。用户设备反馈例如包括接受与拒绝中的一种。例如可以定义1比特的信令open_close_response来进行用户设备反馈，比如1表示接受，0表示拒绝，或者采用相反的定义。
在所接收的消息为允许用户设备使用空闲的CSI-RS端口对应的时 频资源进行数据传输的情况下，用户设备反馈接受表示同意利用上述时频资源，用户设备反馈拒绝表示不同意利用上述时频资源。而在所接收的信息为禁止消息时，用户设备反馈接受表示同意不利用上述时频资源，用户设备反馈拒绝表示不同意不利用上述时频资源，例如在用户设备已使用上述时频资源传输数据的情况下，用户设备对禁止消息反馈拒绝意味着用户设备将继续使用上述时频资源。

此外，判断单元704还可以被配置为：针对每一个小区，判断所确定的与该小区的CSI-RS配置不同的CSI-RS配置的空闲状况是否满足第二预定条件，并且在满足第二预定条件的情况下生成禁止消息，禁止消息表示所述小区被禁止使用空闲的CSI-RS端口进行数据传输。针对与第二预定条件相关的判断可以是在小区使用空闲的CSI-RS端口进行数据传输期间进行的，也可以是在小区没有使用空闲的CSI-RS端口进行数据传输的情况下进行的。
如图13中的另一个虚线框所示，电子设备700还可以包括：收发单元705，被配置为从基站接收相应小区的CSI-RS的端口使用情况。收发单元705例如可以使用天线或通信接口比如收发器实现，确定单元702、 生成单元703和判断单元704例如可以通过一个或多个处理电路来实现，该处理电路例如可以实现为芯片。

<第八实施例>
在上文的实施方式中描述电子设备和信息处理设备的过程中，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电子设备和信息处理设备的过程中公开，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，电子设备和信息处理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电子设备和信息处理设备的硬件和/或固件。
图14示出了根据本申请的一个实施例的用于电子设备的方法的流程图，该方法包括：允许一个小区使用与所述一个小区的自身信道状态信息参考信号CSI-RS配置不同的CSI-RS配置的空闲的CSI-RS端口对应的时频资源的至少一部分进行数据传输(S11)。
如图14中的虚线框所示，该方法还可以包括：确定所述一个小区的相邻小区的CSI-RS的端口使用情况，并基于该端口使用情况确定各个CSI-RS配置的空闲CSI-RS端口对应的时频资源(S12)。此外，虽然图14中示出了步骤S12在步骤S11之前，但是并不限于此，该步骤S12也可以位于步骤S11之后。
此外，在执行步骤S11之前，还可以执行步骤S14：判断空闲CSI-RS端口对应的时频资源是否满足第一预定条件。如果满足第一预定条件(是)，则处理进行到步骤S11。并随后执行步骤S17：生成用于向所述一个小区的用户设备指示能够使用的空闲CSI-RS端口对应的时频资源的指示消息。在步骤S18中接收到来自用户设备的反馈，当反馈接受时，用户设备将使用空闲的CSI-RS资源进行数据传输。该方法在步骤S20中判断空闲CSI-RS端口对应的时频资源是否满足第二预定条件，如果不满足第二预定条件，则处理进行到步骤S20，以周期性地更新CSI-RS配置的CSI-RS端口的使用情况。如果满足第二预定条件，则处理进行到步骤S16：禁止所述一个小区使用所空闲的CSI-RS端口对应的时频资源进行数据传输。接着进行到S19：生成用于向所述一个小区的用户设备指示禁止使用空闲CSI-RS端口对应的时频资源的禁止消息。此外，虽然图中未示出，但是在步骤S19之后，还可以包括接收用户设备反馈的步骤。
另一方面，当步骤S14的判断为不满足第一预定条件时，还可以进行步骤S15：判断空闲CSI-RS端口对应的时频资源是否满足第二预定条件。如果满足第二预定条件，则处理进行到步骤S16和S19。如果不满足第二预定条件，则处理可以进行到步骤S13：周期性地更新CSI-RS配置的CSI-RS端口的使用情况，步骤S13的处理与步骤S20的处理相同。此处，如果本小区尚未使用空闲CSI-RS资源进行数据传输，也可以跳过步骤S15的判断，直接回到步骤S13。
应该理解，虽然图14中示出了该方法的一种流程图的示例，但是本申请的方法的步骤并不限于此，本申请的方法可以仅包括其中的部分处理步骤，或者处理步骤的顺序并不限于图示的顺序。例如，步骤S14和S15的顺序可以互换。
作为一个示例，步骤S14中的第一预定条件为至少一部分CSI-RS 配置的、能够由所述一个小区使用的空闲CSI-RS端口对应的时频资源的数量之和超过第一预定阈值。步骤S15中的第二预定条件为至少一部分CSI-RS配置的、能够由所述一个小区使用的空闲CSI-RS端口对应的时频资源的数量之和低于第二预定阈值。
例如，至少一部分CSI-RS配置包括其空闲CSI-RS端口的数量超过预定值的CSI-RS配置，称为空闲CSI-RS配置。示例性地，每一个空闲CSI-RS配置能够由所述一个小区使用的空闲CSI-RS端口对应的时频资源的数量为小于或等于所述预定值的固定值。在这种情况下，数量之和为空闲CSI-RS配置的数量与固定值的乘积。
对于由两个或多个相邻小区使用的CSI-RS配置，可以将具有最少的CSI-RS空闲端口的相邻小区的CSI-RS配置的空闲CSI-RS端口对应的时频资源的数量作为该CSI-RS配置的空闲CSI-RS端口对应的时频资源的数量。
此外，在步骤S17中生成的指示消息包括各个CSI-RS配置的、所述用户设备能够使用的空闲CSI-RS端口对应的时频资源的数量的信息。例如，可以将用户设备能够使用的各个CSI-RS配置的空闲CSI-RS端口对应的时频资源的数量设置为相同。
在一个示例中，指示消息包括表示各个CSI-RS配置是否有能够使用的空闲CSI-RS端口的位图信息。相应数量为0或位图的相应比特为0，表示相应CSI-RS配置的空闲CSI-RS不可用。
在步骤S19中生成的禁止消息可以为具有特定取值的指示消息，也可以为1比特的指令。
在一个示例中，在步骤S13和S20中可以根据来自相邻小区的基站的X2信令来获得该相邻小区的CSI-RS端口的使用情况。X2信令例如为ENB CONFIGURATION UPDATE消息，该ENB CONFIGURATION UPDATE中包括指示该相邻小区的CSI-RS配置中的各个CSI-RS端口的使用状况的信息的信息单元。该信息单元例如具有位图的形式，位图的比特数根据CSI-RS配置的CSI-RS端口数确定，例如，位图的一个比特为0表示相应CSI-RS端口未被使用，位图的一个比特为1表示相应CSI-RS端口正被使用。该信息单元可以包括在ENB CONFIGURATION  UPDATE消息的信息单元Served Cell Information中。
此外，在步骤S13和S20中，也可以通过接收来自中央管理装置的信息来更新CSI-RS端口的使用情况。
相应地，虽然图14中未示出，但是该方法还可以包括接收包含CSI-RS的端口使用情况的信息的步骤。并且，该方法还可以包括向用户设备发送指示消息或禁止消息的步骤。
图15示出了根据本申请的另一个实施例的用于电子设备的方法的流程图，该方法包括：基于从基站接收的消息确定用户设备能够用来进行数据传输的与所述基站使用的自身CSI-RS配置不同的CSI-RS配置的空闲的CSI-RS端口对应的时频资源(S21)；以及生成包含用户设备反馈的消息(S22)。例如，该用户设备反馈包括接受与拒绝中的一种。
当从基站接收的消息为禁止消息或者所确定的时频资源的数量为0时，用户设备被禁止使用空闲的CSI-RS端口对应的时频资源进行数据传输。
如图15中的虚线框所示，该方法还可以包括：步骤S23，从基站接收消息；以及步骤S24，向基站发送包含用户设备反馈的消息。
图16示出了根据本申请的又一个实施例的用于电子设备的方法的流程图，该方法包括：存储各个小区的CSI-RS的端口使用情况(S31)；以及针对每一个小区，确定其相邻小区的CSI-RS的端口使用情况(S32)。
此外，如图中的虚线框所示，该方法还可以包括步骤S33：从基站接收相应小区的CSI-RS的端口使用情况。
上述方法还可以包括步骤S34：基于端口使用情况确定与所述一个小区的自身CSI-RS配置不同的CSI-RS配置的空闲CSI-RS端口对应的时频资源。可以接着执行步骤S37和步骤S38，其中，步骤S37为生成包含与所述一个小区的自身CSI-RS配置不同的CSI-RS配置的空闲CSI-RS端口对应的时频资源的信息的消息，步骤S38为向相应的小区的基站发送所生成的该消息。此外，在不执行步骤S34的情况下，在步骤S38中还可以发送步骤S32中确定的端口使用情况。
上述方法还可以包括步骤S35：针对每一个小区，判断所确定的与 该小区的CSI-RS配置不同的CSI-RS配置的CSI-RS端口的空闲状况是否满足第一预定条件。如果满足第一预定条件(是)，则进行到步骤S37以生成所述消息。如果不满足第一预定条件(否)，则进行到步骤S36：针对每一个小区，判断所确定的与该小区的CSI-RS配置不同的CSI-RS配置的空闲状况是否满足第二预定条件。如果满足第二预定条件(是)，则进行到步骤S39：生成禁止消息，该禁止消息表示相应小区被禁止使用空闲的CSI-RS端口进行数据传输。如果不满足第二预定条件(否)，则返回到步骤S32继续更新相邻小区的CSI-RS的端口使用情况。应该理解，也可以仅进行第一预定条件的判断，当不满足第一预定条件时，即返回步骤S32，或者仅进行第二预定条件的判断。
注意，上述各个方法可以结合或单独使用，其细节在第一至第八实施例中已经进行了详细描述，在此不再重复。
为了便于理解，以下将参照图17示出基站与用户设备间的示例性信息流程。其中基站可以包括前文所述的电子设备100-300或信息处理设备400中的任意一个，用户设备可以包括前文所述的电子设备500或信息处理设备600中的任意一个。应该理解，这些信息流程仅是为了说明的用途，而不是限制性的。
图17示出了基站与用户设备(UE)以及基站之间的信息流程的一个示例。其中，将要利用空闲CSI-RS资源进行数据传输的小区的基站作为基站1，基站1的相邻基站为处于小区1的干扰范围内的小区的基站。注意，图17中虽然示出了一个相邻基站，但是相邻基站的数量并不一定为1，而是可能有多个，这里仅是一个示例。
在图17中，相邻基站向其各个用户设备发送波束赋形CSI-RS，用户设备进行测量之后，向该相邻基站发送CSI反馈，从而该相邻基站能够获得CSI-RS的端口使用情况。随后，该相邻基站向基站1提供该端口使用状况。在图17中通过X2信令ENB CONFIGURATION UPDATE来传递CSI-RS的端口使用情况，具体地，例如可以通过前文所述的在ENB CONFIGURATION UPDATE消息的信息单元Served Cell Information中增加新的信息单元Antenna_ports-usage来承载CSI-RS的端口使用情况的信息，信息单元Antenna_ports-usage例如可以具有位图的形式。基站1在收到ENB CONFIGURATION UPDATE之后，向相 应的相邻基站发送ENB CONFIGURATION UPDATE ACKNOWLEDGE来确认收到该消息。
接下来，基站1对接收到的来自(多个)相邻基站的CSI-RS的端口使用情况进行处理，例如获得各个CSI-RS配置的CSI-RS的空闲端口的数量，并判断CSI-RS端口的空闲状况是否满足第一预定条件。如果满足第一预定条件，则向基站1的用户设备发送指示其能够使用的空闲CSI-RS资源的指示消息Allowed_Reresource，该指示消息相当于开启利用空闲CSI-RS资源的消息。其中，关于第一预定条件和指示消息的描述请参见前文的细节。
基站1的用户设备接收到指示消息后，向基站1发出用户设备反馈Open_close_response，以告知基站1其接受或拒绝上述指示消息指示的开启。比如，在Open_close_response为1时表示接受开启，Open_close_response为0时表示拒绝开启。
图18示出了在基站1使用空闲CSI-RS资源进行数据传输期间，基站与用户设备(UE)以及基站之间的信息流程的一个示例。其中，与图17相比，增加了在基站1使用空闲CSI-RS资源进行数据传输期间，对来自相邻基站的CSI-RS端口的空闲状况进行是否满足第二预定条件的判断。
图18中示出了不满足第二预定条件的情形。此时将向用户设备提供其能够使用的空闲CSI-RS资源的指示消息Allowed_Reresource，以使得用户设备能够继续使用当前空闲的CSI-RS资源进行数据传输。类似地，用户设备还向基站1发送用户设备反馈。
图19示出了在基站1使用空闲CSI-RS资源进行数据传输期间，基站与用户设备(UE)以及基站之间的信息流程的另一个示例。在该示例中，满足第二预定条件，基站1向用户设备发送禁止消息，以禁止用户设备使用空闲的CSI-RS资源进行数据传输。类似地，用户设备还向基站1发送用户设备反馈。
图20-22示出了基站通过中央管理装置来获取有关空闲CSI-RS资源的信息的信息流程的示例。应该注意，在基站与其用户设备侧的流程可以与图17-19中的相同，因此，图中仅示出了与图17的情况相同的部分， 但是图18和图19的情况同样适用于图20-22的基站与其用户设备侧的信息交互部分。
在图20-22中，左侧的基站代表中央管理装置所管理的各个基站，其包括基站1。在图20中，基站1从中央管理装置获取CSI-RS端口的使用状况，并根据该使用状况获得各个CSI-RS配置的空闲的CSI-RS资源，判断是否满足第一预定条件。在满足第一预定条件的情况下，指示用户设备使用空闲的CSI-RS资源进行数据传输。
在图21中，由中央管理装置对CSI-RS端口的使用状况进行进一步处理，以获得各个CSI-RS配置的空闲的CSI-RS资源，并将相关信息提供给基站1。基站1判断是否满足第一预定条件。在满足第一预定条件的情况下，指示用户设备使用空闲的CSI-RS资源进行数据传输。
而在图22中，中央管理装置对各个CSI-RS配置的空闲的CSI-RS资源进行进一步处理，例如进行是否满足第一预定条件等的判断，从而获得基站1能够使用的空闲的CSI-RS资源，并将其提供给基站1。在这种情况下，基站1不需要再进行任何处理，可以直接指示用户设备使用这些CSI-RS资源进行数据传输。
此外，关于本技术的描述同样地适用于使用Cell-Specific波束赋形CSI-RS、UE-Specific波束赋形CSI-RS、非周期波束赋形CSI-RS或其任意组合的情况。
