Description

CSI测量方法和装置
技术领域 本发明涉及通信领域， 具体而言， 涉及一种信道状态信息 （Channel State Information, 简称 CSI) 测量方法和装置。 背景技术 根据技术规范 3GPP TS 36.211， 长期演进（Long Term Evolution, 简称为 LTE)时 分双工 （Time Division Duplex, 简称为 TDD) 系统的帧结构如图 1所示， 一个无线帧 (Radio frame)长度为 Tf=307200Ts=10ms， 包括两个长度为 5ms的半帧， 每个半帧由 5个长度为 lms的子帧组成。 该帧结构支持的上下行配置如表 1所示， 其中， D表示 子帧用于下行传输， U表示子帧用于上行传输， S表示特殊子帧且包含三个特殊时隙， 这三个特殊时隙分别为： 用于下行传输的下行导频时隙（Downlink Pilot Time Slot, 简 称为 DwPTS)、 保护间隔 （Guard Period, 简称为 GP) 和用于上行传输的上行导频时 隙 （Uplink Pilot Time Slot, 简称为 UpPTS)。 表 1
Figure imgf000003_0001
目前， 在 LTE TDD系统中， 各个小区基站 （例如演进的节点 B， 即 eNodeB, 简 称为 eNB) 通过广播消息把上下行配置信息发送给终端。 为了控制小区间干扰， 各个 小区基站通常采用相同的上下行配置， 因此， 基站进行下行传输时主要会受到其他基 站下行传输产生的干扰， 终端进行上行传输时主要会受到其他小区终端上行传输产生 的干扰。
TDD elMTA ( enhanced Interference Management and Traffic Adaptation? 简禾尔为 elMTA) 允许基站根据小区业务负载变化灵活调整上下行配置， 当不同小区基站的上 下行配置不同时， 基站进行下行传输、 终端进行上行传输在不同子帧上受到的干扰可 能会发生显著变化。例如，如图 2所示，在图 2的（a)中基站 eNBl在无线帧 Radio frame #1 (无线帧 1 ) 和 Radio frame #2分别采用了上下行配置 Config. 0 (配置方式 0) 和 Config. 2， 在图 2的（b)中基站 eNB2在无线帧 Radio frame #1和 Radio frame #2分别 采用了上下行配置 Config. 2和 Config. 1。 因此， eNB2在 Radio frame #1的第 0/1/5/6 个子帧和 Radio frame #2的第 0/1/4/5/6/9个子帧进行下行传输时会受到 eNBl在相应子 帧进行下行传输的干扰， 而 eNB2在 Radio frame #1的第 3/4/8/9个子帧进行下行传输 则会受到 eNBl服务小区中的终端进行上行传输的干扰。因此， eNB2进行下行传输时， 在 Radio frame #1的第 3/4/8/9个子帧上受到的干扰情况与其在 Radio frame #1的第 0/1/5/6个子帧以及 Radio frame #2的第 0/1/4/5/6/9个子帧上受到的干扰情况可能会明 显不同。 其中， 在 Radio frame #1的第 3/4/8/9个子帧上受到的干扰情况与干扰源小区 终端的上行发射功率、 干扰源小区终端与被干扰小区终端的距离等因素有关。
LTE系统支持通过配置信道状态信息干扰测量资源 （例如， 基于零功率信道状态 信窗、参考信号酉己置的 Channel State Information-Interference Measurement Resource, 简 称 CSI-IM资源）进行干扰测量， 从而获得 CSI的测量报告。例如， 如图 3所示， eNBl 与 eNB2的上下行配置与图 2相同， eNB2在每个无线帧的第 0个子帧和第 5个子帧上 配置了一套 CSI-IM资源 （即， 图 3中的 1)， 供终端执行周期 5ms的干扰测量， 用于 获取包含 eNBl 下行传输产生的干扰的干扰信息， 从而获取并报告反映信道状况的 CSI, 用于链路自适应传输。 或者， 如图 4所示， 其中， eNBl与 eNB2的上下行配置与图 2相同， eNB2在每 个无线帧的第 0个子帧和第 5个子帧上配置了两套 CSI-IM资源 （SP， 图 4中的 II和 12)，供终端执行周期 5ms的干扰测量， eNBl在与 eNB2配置的第一套 CSI-IM资源相 同的时频资源位置处也配置了 CSI-IM资源，这样从 eNB2获取服务的终端可以通过第 一套 CSI-IM 资源获取不包含 eNBl 下行传输产生的干扰的干扰信息， 通过第二套 CSI-IM资源获取包含 eNBl下行传输产生的干扰的干扰信息， 从而获取并报告反映不 同信道状况的两套 CSI， 用于链路自适应传输或协作多点传输。 然而， 在 TDD elMTA中， 通过上述 CSI测量报告方法获取 CSI， 无法有效反映小 区基站灵活调整上下行配置时基站在不同子帧进行下行传输受到的干扰发生显著变化 的情况， 例如： 现有技术中 CSI-IM资源配置周期为 5ms的倍数， 受限于此， 上述 CSI 测量报告方法无法同时获取能够反映图 2所示的 eNB2在 Radio frame #1的第 3/4/8/9 个子帧上进行下行传输受到的干扰情况的 CSI。 另外存在的一个问题是， 基站采用的上下行配置改变， 会导致其配置了信道状态 信息干扰测量资源的子帧的传输方向发生变化，此时如果不对子帧传输方向进行判断， 终端就无法获知信道状态信息干扰测量资源所在子帧是否为下行子帧， 就会出现终端 对非下行子帧进行干扰测量的状况， 从而导致终端在该子帧上执行干扰测量操作失败 或者获取的干扰测量结果不准确。 针对上述的问题， 目前尚未提出有效的解决方案。 发明内容 本发明实施例提供了一种 CSI测量方法和装置， 以至少解决现有技术中由于基站 灵活调整上下行配置而导致的难以有效进行 CSI测量的技术问题。 根据本发明实施例的一个方面， 提供了一种 CSI测量方法， 包括： 终端设备确定 信道状态信息干扰测量资源所在子帧是否为下行子帧； 如果是， 则所述终端设备通过 所述信道状态信息干扰测量资源执行干扰测量。 优选地， 所述终端设备通过以下方式至少之一确定所述信道状态信息干扰测量资 源所在子帧是否为下行子帧： 所述终端设备根据从网络侧设备接收的上下行配置信息 确定所述信道状态信息干扰测量资源所在子帧是否为下行子帧； 所述终端设备根据从 所述网络侧设备接收的与所述信道状态信息干扰测量资源所在子帧对应的下行调度信 息确定所述信道状态信息干扰测量资源所在子帧是否为下行子帧； 所述终端设备根据 从所述网络侧设备接收的所述信道状态信息干扰测量资源所在子帧上的下行控制信道 确定所述信道状态信息干扰测量资源所在子帧是否为下行子帧； 所述终端设备根据从 所述网络侧设备接收的与所述信道状态信息干扰测量资源所在子帧对应的 CSI测量报 告触发信息确定所述信道状态信息干扰测量资源所在子帧是否为下行子帧。 优选地， 在终端设备确定信道状态信息干扰测量资源所在子帧是否为下行子帧之 前， 上述方法还包括： 所述终端设备接收网络侧设备发送的配置信息， 其中， 所述配 置信息用于指示所述网络侧设备为多个子帧组配置的信道状态信息干扰测量资源， 其 中， 所述多个子帧组中的每个子帧组包括一个或多个子帧。 优选地， 所述多个子帧组包括： 第一子帧组和第二子帧组。 优选地， 所述第一子帧组包括传输方向固定为下行的下行子帧， 所述第二子帧组 包括传输方向允许进行调整的子帧； 或者， 所述第一子帧组包括当前网络侧设备配置 为下行传输子帧， 且与所述当前网络侧设备之间的距离小于预定阈值的网络侧设备也 将对应于所述下行传输子帧的位置的子帧配置为下行传输子帧的子帧， 所述第二子帧 组包括所述当前网络侧设备配置为下行传输子帧， 且与所述当前网络侧设备之间的距 离小于所述预定阈值的网络侧设备将对应于所述下行传输子帧的位置的子帧配置为上 行传输子帧的子帧； 或者， 所述第一子帧组包括终端设备测量报告的信道状态信息小 于预设门限的下行子帧， 所述第二子帧组包括终端设备测量报告的信道状态信息高于 所述预设门限的下行子帧。 优选地， 所述网络侧设备为所述终端设备的多个子帧组配置的信道状态信息干扰 测量资源包括以下至少之一： 所述网络侧设备为所述多个子帧组中的不同子帧组配置 周期的信道状态信息干扰测量资源； 所述网络侧设备为所述多个子帧组中的不同子帧 组配置非周期触发的信道状态信息干扰测量资源。 优选地， 所述网络侧设备为所述多个子帧组中的不同子帧组配置非周期触发的信 道状态信息干扰测量资源是所述网络侧设备根据 CSI测量报告触发信息配置的。 优选地， 所述 CSI测量报告触发信息包括： 下行控制信息 DCI中的信道状态信息 请求 CSI request。 优选地， 所述网络侧设备为所述终端设备的多个子帧组配置的信道状态信息干扰 测量资源包括： 所述网络侧设备为所述多个子帧组中的不同子帧组配置的信道状态信 息干扰测量资源位于不同的子帧。 优选地， 所述网络侧设备通过子帧偏移的大小的不同来指示与所述多个子帧组中 的不同子帧组对应的信道状态信息干扰测量资源位于不同的子帧。 优选地， 在所述网络侧设备通过半静态方式确定所述多个子帧组的情况下， 所述 多个子帧组是所述网络侧设备以多个无线帧为周期确定的； 在所述网络侧设备通过动 态方式确定所述多个子帧组的情况下， 所述多个子帧组是所述网络侧设备以一个无线 帧为周期确定的。 优选地， 在所述网络侧设备通过半静态方式确定所述多个子帧组的情况下， 所述 网络侧为所述多个无线帧中的各个无线帧配置相同的多个子帧组。 优选地， 所述配置信息还用于指示所述多个子帧组中各个子帧组配置了信道状态 信息干扰测量资源的子帧， 和 /或各个配置了所述信道状态信息干扰测量资源的子帧所 属的子帧组。 优选地， 所述终端设备通过所述信道状态信息干扰测量资源执行干扰测量包括： 所述终端设备通过所述信道状态信息干扰测量资源执行干扰测量； 所述终端设备根据 所述配置信息确定所述信道状态信息干扰测量资源所在的子帧所属的子帧组， 将执行 所述干扰测量得到的测量结果作为确定的子帧组的测量结果。 优选地， 在所述终端设备根据所述配置信息确定所述信道状态信息干扰测量资源 所在的子帧所属的子帧组， 将执行所述干扰测量得到的测量结果作为确定的子帧组的 测量结果之后， 所述方法还包括： 所述终端设备根据测量结果确定与所述信道状态信 息干扰测量资源所在子帧所属的子帧组对应的 CSI;

#2分别采用了上下行配置 Config. 0和 Config. 2， 在图 2的 （b) 中基站 eNB2在无线 帧 Radio frame #1和 Radio frame #2分别采用了上下行配置 Config. 2和 Config. 1。 在本优选实施例中， 以 eNB2为例， eNB2可以采用以下方式确定多个子帧组（在 本实施例中以两个子帧组为例进行说明， 即多个子帧组至少包括第一子帧组和第二子 帧组）： 方式一： eNB2静态确定多个子帧组， 并且，把传输方向固定为下行的下行子帧作 为第一子帧组， 把传输方向允许进行调整的子帧作为第二子帧组。 从上述表 1可以看 出， 在不同的上下行配置中， 第 0/1/5/6个子帧固定用于下行业务传输， 第 2个子帧固 定用于上行业务传输， 第 3/4/7/8/9个子帧或用于上行业务传输或用于下行业务传输， 也就是说第 3/4/7/8/9个子帧的传输方向允许进行调整。 假设 eNB2可以从表 1所示的 7种上下行配置中灵活选择上下行配置作为其无线帧结构进行业务传输，则 eNB2可以 把每个无线帧中的第 0/1/5/6个子帧作为第一子帧组，把每个无线帧中的第 3/4/7/8/9个 子帧作为第二子帧组。 方式二： eNB2以多个无线帧为周期半静态确定多个子帧组， 并且，根据当前周期 内首个无线帧的上下行配置， 把传输方向固定为下行的下行子帧作为第一子帧组， 把 传输方向允许进行调整的下行子帧作为第二子帧组。 则 eNB2根据无线帧 Radio frame #1采用的上下行配置 Config. 2， 把传输方向固定为下行的第 0/1/5/6个下行子帧作为 第一子帧组， 把传输方向允许进行调整的第 3/4/8/9个下行子帧作为第二子帧组。 方式三： eNB2以多个无线帧为周期半静态确定多个子帧组， 并且，根据当前周期 内首个无线帧的上下行配置， 把 eNB2配置为下行传输子帧且与 eNB2之间的距离小 于预定阈值的 eNB (假设为 eNBl ) 也将对应位置的子帧配置为下行传输子帧的子帧 作为第一子帧组， 把 eNB2配置为下行传输子帧且与 eNB2之间的距离小于预定阈值 的 eNBl将对应位置的子帧配置为上行传输子帧的子帧作为第二子帧组。 则 eNB2根 据其在无线帧 Radio frame #1采用的上下行配置 Config. 2， 以及 eNBl在无线帧 Radio frame #1采用的上下行配置 Config. 0， 把第 0/1/5/6个下行子帧作为第一子帧组， 把第 3/4/8/9个下行子帧作为第二子帧组。 方式四： eNB2以多个无线帧为周期半静态确定多个子帧组， 并且，根据终端设备 测量报告的信道状态信息 （例如： 调制编码方式， 在系统中每个调制编码方式对应一 个序号， 按照调制编码方式对应的序号进行后续的分组判断）， 把信道状态信息（即调 制编码方式的序号） 小于预设门限的下行子帧作为第一子帧组， 把信道状态信息高于 预设门限的下行子帧作为第二子帧组。 其中， 对于信道状态信息小于预设门限的下行 子帧， 基站认为这些子帧上受到了较大的干扰； 对于信道状态信息高于预设门限的下 行子帧，基站认为这些子帧上受到了较小的干扰。例如， eNB2可以根据终端设备测量 报告的信道状态信息，把第 0/1/5/6个子帧作为第一子帧组，把第 3/4/7/8/9个子帧作为 第二子帧组。 方式五： eNB2以一个无线帧为周期动态确定多个子帧组，根据当前无线帧的上下 行配置， 把传输方向固定为下行的下行子帧作为第一子帧组， 把传输方向允许进行调 整的下行子帧作为第二子帧组。则对于 Radio frame #1，其采用的上下行配置为 Config. 2， eNB2把传输方向固定为下行的第 0/1/5/6个下行子帧作为第一子帧组，把传输方向 允许进行调整的第 3/4/8/9个下行子帧作为第二子帧组； 对于 Radio frame #2， 其采用 的上下行配置为 Config. 1， eNB2把传输方向固定为下行的第 0/1/5/6个下行子帧作为 第一子帧组， 把传输方向允许进行调整的第 4/9个下行子帧作为第二子帧组。 方式六： eNB2以一个无线帧为周期动态确定多个子帧组， 并且，根据当前无线帧 的上下行配置， 把 eNB2配置为下行传输子帧且与 eNB2之间的距离小于预定阈值的 eNB (假设为 eNBl )也将对应位置的子帧配置为下行传输子帧的子帧作为第一子帧组， 把 eNB2配置为下行传输子帧且与 eNB2之间的距离小于预定阈值的 eNBl将对应位置 的子帧配置为上行传输子帧的子帧作为第二子帧组。 则对于 Radio frame #1 , eNB2采 用的上下行配置为 Config. 2， eNBl采用的上下行配置为 Config. 0， eNB2把第 0/1/5/6 个下行子帧作为第一子帧组， 把第 3/4/8/9个下行子帧作为第二子帧组； 对于 Radio frame #2, eNB2采用的上下行配置为 Config. 1， eNBl采用的上下行配置为 Config. 2， eNB2把第 0/1/4/5/6/9个下行子帧均作为第一子帧组，第二子帧组为空或者无第二子帧 组。 优选实施例 2 在本优选实施例中， 主要介绍终端设备如何确定信道状态信息干扰测量资源所在 子帧是否为下行子帧， 下面给出了几个具体的确定方式： 方式一： 终端设备根据从基站接收的上下行配置信息（如表 1所示）， 确定当前无 线帧中信道状态信息干扰测量资源所在子帧的传输方向是否为下行， 包括是否为 D或 是否为 S， 如果为 D或为 S， 则终端设备确定该子帧为下行子帧。 方式二： 终端设备根据从基站接收的下行调度信息， 确定信道状态信息干扰测量 资源所在子帧是否为下行子帧。 例如， 对于多子帧调度， 基站可以通过某个下行子帧 的下行控制信道发送多个下行子帧的下行调度信息， 如果终端设备接收到基站发送的 与信道状态信息干扰测量资源所在子帧对应的下行调度信息， 则终端确定该子帧为下 行子帧； 对于单子帧调度， 基站通过当前下行子帧的下行控制信道发送当前下行子帧 的下行调度信息， 如果终端设备通过检测当前子帧的下行控制信道获取到下行调度信 息， 则终端确定该子帧为下行子帧。 方式三： 终端设备检测信道状态信息干扰测量资源所在子帧的下行控制信道 （例 如物理下行控制信道 PDCCH), 如果检测成功， 则终端设备确定该子帧为下行子帧。 方式四： 终端设备根据从基站接收的 CSI测量报告触发信息确定子帧为是否下行 且存在信道状态信息干扰测量资源。 如果终端设备从基站接收到与一个子帧对应的 CSI 测量报告触发信息， 则终端设备确定该子帧为下行且该子帧上存在信道状态信息 干扰测量资源， 或者， 如果终端通过检测一个子帧的下行控制信道获取到 CSI测量报 告触发信息， 则终端设备确定该子帧为下行且该子帧上存在信道状态信息干扰测量资 源。 优选实施例 3 如图 10所示， 图 10中 （a) 所示的基站 eNBl与图 10中 （b) 所示的基站 eNB2 的上下行配置与图 2相同。 本实施例中， eNB2按照优选实施例 1中的方式二或方式三以无线帧长度的 2倍（即 20ms) 为周期半静态确定不同子帧组， 则在当前的 Radio frame #1和 Radio

3个子帧不是下行子帧，则终端 在该子帧不执行干扰测量； 终端确定 Radio frame #2上 CSI-IM资源所在的第 5个子帧为下行子帧，则终端通 过 CSI-IM资源执行干扰测量， 获取与该子帧所属第一子帧组对应的干扰测量结果； 终端确定 Radio frame #2上 CSI-IM资源所在的第 8个子帧不是下行子帧，则终端 在该子帧不执行干扰测量。 其中， 终端确定

#2分别采用了上下行配置 Config. 0和 Config. 2， 图 12中 （b)所示的基站 eNB2在无 线帧 Radio frame #1和 Radio frame #2均采用了上下行配置 Config. 2。 本实施例中， eNB2按照优选实施例 1中的方式二或方式三以无线帧长度的 2倍（即 20ms) 为周期半静态确定不同子帧组， 则在当前的 Radio frame #1和 Radio frame #2 中， eNB2把每个无线帧中用于下行传输的第 0/1/5/6个子帧确定为第一子帧组， 把每 个无线帧中用于下行传输的第 3/4/8/9个子帧确定为第二子帧组。 eNB2为第一子帧组配置 CSI-IM资源 1， 即 eNB2在每个无线帧的第 0个、 第 5 个子帧上配置周期 5ms的 CSI-IM资源， 用于供终端对第一子帧组执行干扰测量； eNB2为第二子帧组配置 CSI-IM资源 2， 即 eNB2在每个无线帧的第 3个、 第 8 个子帧上配置周期 5ms的 CSI-IM资源， 用于供终端对第二子帧组执行干扰测量。 eNB2把与不同子帧组对应的 CSI-IM资源配置信息发送给终端， 用于供终端执行 干扰测量， 获取与不同子帧组对应的干扰测量结果以及 CSI。 eNB2把不同子帧组信息发送给终端， 用于供终端确定 CSI-IM资源所在子帧属于 哪一个子帧组。 终端接收 CSI-IM 资源配置信息和子帧组信息， 在 CSI-IM 资源所在子帧通过 CSI-IM资源执行干扰测量， 获取与 CSI-IM资源所在子帧所属子帧组对应的干扰测量 结果， 例如： 终端确定 Radio frame #1上 CSI-IM资源所在的第 0个子帧为下行子帧，则终端通 过 CSI-IM资源执行干扰测量， 获取与该子帧所属第一子帧组对应的干扰测量结果； 终端确定 Radio frame #1上 CSI-IM资源所在的第 3个子帧为下行子帧，则终端通 过 CSI-IM资源执行干扰测量， 获取与该子帧所属第二子帧组对应的干扰测量结果。 其中， 终端确定 CSI-IM 资源所在子帧是否为下行子帧， 包括： 终端根据从基站 接收的上下行配置信息确定该子帧是否为下行子帧； 或者， 终端根据从基站接收的与 该子帧对应的下行调度信息确定该子帧为下行子帧； 或者， 终端根据从基站接收的该 子帧上的下行控制信道 （例如物理下行控制信道 PDCCH) 或下行控制信息 DCI确定 该子帧为下行子帧。 终端确定与不同子帧组对应的 CSI， 包括： 终端根据在 CSI-IM资源所在子帧获取 的与该子帧所属子帧组对应的干扰测量结果， 确定与相应子帧组对应的 CSI， 例如： 终端根据在 Radio frame #1的第 0个子帧上获取的与该子帧所属第一子帧组对应 的干扰测量结果， 确定与第一子帧组对应的 CSI; 终端根据在 Radio frame #1的第 3个子帧上获取的与该子帧所属第二子帧组对应 的干扰测量结果， 确定与第二子帧组对应的 CSI。 终端把所确定的与不同子帧组对应的 CSI发送给 eNB2，供 eNB2用于下行链路自 适应， 过程同优选实施例 3。 优选实施例 6 如图 13所示， 图 13中 （a)所示的基站 eNBl与图 13中 （b)所示的基站 eNB2 的上下行配置与图 12相同。 本实施例中， eNB2按照优选实施例 1 中的方式六动态确定不同子帧组， 则对于 Radio frame #1， eNB2把该无线帧中用于下行传输的第 0/1/5/6个子帧确定为第一子帧 组， 将该无线帧中用于下行传输的第 3/4/8/9个子帧确定为第二子帧组， 对于 Radio frame #2, eNB2把该无线帧的所有用于下行传输的子帧均确定为第一子帧组。 eNB2在每个无线帧的第 0个、第 5个子帧上配置周期 5ms的 CSI-IM资源， 在每 个无线帧的第 3个、 第 8个子帧上配置周期 5ms的 CSI-IM资源。 eNB2把 CSI-IM资源配置信息发送给终端， 用于供终端执行干扰测量， 获取与不 同子帧组对应的干扰测量结果以及 CSI。 eNB2把不同子帧组信息发送给终端， 用于供终端确定 CSI-IM资源所在子帧属于 哪一个子帧组。 终端接收 CSI-IM 资源配置信息和子帧组信息， 在 CSI-IM 资源所在子帧通过 CSI-IM资源执行干扰测量， 获取与 CSI-IM资源所在子帧所属子帧组对应的干扰测量 结果， 例如： 对于 Radio frame #1上 CSI-IM资源所在的第 0个子帧，终端确定该子帧为下行子 帧且该子帧属于第一子帧组， 则终端通过 CSI-IM资源执行干扰测量， 获取与该子帧 所属第一子帧组对应的干扰测量结果； 对于 Radio frame #1上 CSI-IM资源所在的第 3个子帧，终端确定该子帧为下行子 帧且该子帧属于第二子帧组， 则终端通过 CSI-IM资源执行干扰测量， 获取与该子帧 所属第二子帧组对应的干扰测量结果； 而对于 Radio frame #2上 CSI-IM资源所在的第 3个子帧，终端确定该子帧为下行 子帧且该子帧属于第一子帧组， 则终端通过 CSI-IM资源执行干扰测量， 获取与该子 帧所属第一子帧组对应的干扰测量结果。 其中， 终端确定 CSI-IM资源所在子帧是否为下行子帧， 包括： 终端根据从基站 接收的上下行配置信息确定该子帧是否为下行子帧； 或者， 终端根据从基站接收的与 该子帧对应的下行调度信息确定该子帧为下行子帧； 或者， 终端根据从基站接收的该 子帧上的下行控制信道 （例如物理下行控制信道 PDCCH) 或下行控制信息 DCI确定 该子帧为下行子帧。 终端确定与不同子帧组对应的 CSI， 包括： 终端根据在 CSI-IM资源所在子帧获取 的与该子帧所属子帧组对应的干扰测量结果， 确定与相应子帧组对应的 CSI， 例如： 终端根据在 Radio frame #1的第 0个子帧上获取的与该子帧所属第一子帧组对应 的干扰测量结果， 确定与第一子帧组对应的 CSI; 终端根据在 Radio frame #1的第 3个子帧上获取的与该子帧所属第二子帧组对应 的干扰测量结果， 确定与第二子帧组对应的 CSI; 而对于终端在 Radio frame #2的第 3个子帧上获取的与该子帧所属第一子帧组对 应的干扰测量结果， 则可以用于供终端确定与第一子帧组对应的 CSI。 终端把所确定的与不同子帧组对应的 CSI发送给 eNB2，供 eNB2用于下行链路自 适应， 过程同优选实施例 3。 在上述各个优选实施例中， 通过终端设备在与不同子帧组对应的信道状态信息干 扰测量资源所在子帧为下行子帧时实施干扰测量， 获取与不同子帧组对应的 CSI， 并 报告给网络侧设备，解决了相关技术中基站灵活调整上下行配置引起的 CSI测量问题， 进而达到了提高系统数据传输性能的效果。 在另外一个实施例中， 还提供了一种软件， 该软件用于执行上述实施例及优选实 施方式中描述的技术方案。 在另外一个实施例中， 还提供了一种存储介质， 该存储介质中存储有上述软件， 该存储介质包括但不限于： 光盘、 软盘、 硬盘、 可擦写存储器等。 需要说明的是， 以上各实施例及优选实施例中所描述的 CSI测量方法和装置及其 对应的软件和存储介质中， 信道状态信息干扰测量资源可以是基于零功率信道状态信 息参考信号配置的 CSI-IM资源， 也可以是其他类型的信道状态信息干扰测量资源。 从以上的描述中， 可以看出， 本发明实现了如下技术效果： 终端设备先确定信道 状态信息干扰测量资源所在的子帧是否为下行子帧， 只有在确定信道状态信息干扰测 量资源所在子帧是下行子帧的情况下， 终端才在该信道状态信息干扰测量资源上执行 干扰测量。 通过上述方式有效解决了相关技术中基站灵活调整上下行配置而导致的难 以有效进行 CSI测量的技术问题， 达到了提高系统数据传输性能的技术效果。 显然， 本领域的技术人员应该明白， 上述的本发明的各模块或各步骤可以用通用 的计算装置来实现， 它们可以集中在单个的计算装置上， 或者分布在多个计算装置所 组成的网络上， 可选地， 它们可以用计算装置可执行的程序代码来实现， 从而， 可以 将它们存储在存储装置中由计算装置来执行， 并且在某些情况下， 可以以不同于此处 的顺序执行所示出或描述的步骤， 或者将它们分别制作成各个集成电路模块， 或者将 它们中的多个模块或步骤制作成单个集成电路模块来实现。 这样， 本发明不限制于任 何特定的硬件和软件结合。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本领域的技 术人员来说， 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内， 所作的 任何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。
