具体实施方式detailed description

为了使本发明的目的、技术方案及优点更加清楚明白，下面结合附图并据实施例，对本发明的技术方案进行详细说明。In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

在长期演进技术(LongTermEvolution，LTE)系统中，基站不做功率控制，终端设备接收到的信号强度比较稳定。若在该终端设备接收信号的频带的相邻频道上存在发射信号的终端设备，会对接收到的信号强度带来干扰。In a Long Term Evolution (Long Term Evolution, LTE) system, the base station does not perform power control, and the signal strength received by the terminal equipment is relatively stable. If there is a terminal device transmitting signals on an adjacent channel of a frequency band in which the terminal device receives signals, it will cause interference to received signal strength.

本申请具体实施例中，记录当前时刻前预设时间内接收到的信号的总强度，并计算在预设时间内的平均信号强度。该预设时间可以为预设个数个传输时间间隔(TransmissionTimeInterval，TTI)，也可以是根据实际需要配置的时间段。其中，接收到的信号的强度包括服务信号的强度和干扰信号的强度。In a specific embodiment of the present application, the total strength of signals received within a preset time before the current moment is recorded, and the average signal strength within the preset time is calculated. The preset time may be a preset number of transmission time intervals (Transmission Time Interval, TTI), or may be a time period configured according to actual needs. Wherein, the strength of the received signal includes the strength of the serving signal and the strength of the interference signal.

当在某一时刻确定该时刻接收到的信号的总强度与预设时间内平均信号强度的差值大于第一阈值时，终端设备确定有一个相邻频带正在被其他终端用于发射信号，对本终端设备接收数据产生了干扰，此时，需要执行本申请提供的实施例，进行邻频终端间干扰的避免。When it is determined at a certain moment that the difference between the total strength of the received signal at that moment and the average signal strength within a preset time is greater than the first threshold, the terminal device determines that an adjacent frequency band is being used by other terminals to transmit signals, and the The data received by the terminal equipment generates interference. At this time, it is necessary to implement the embodiments provided in this application to avoid interference between adjacent frequency terminals.

本申请实施例中的终端设备为FDD终端设备或TDD终端设备，FDD终端设备为FDD系统中的终端设备，TDD终端设备为TDD系统中的终端设备。The terminal device in the embodiment of the present application is an FDD terminal device or a TDD terminal device, the FDD terminal device is a terminal device in an FDD system, and the TDD terminal device is a terminal device in a TDD system.

下面结合附图，详细说明本申请实施例中如何实现终端设备调度的。How to implement terminal device scheduling in the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

参见图1，图1为本申请实施例中终端设备调度方法流程示意图。具体步骤为：Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a terminal device scheduling method in an embodiment of the present application. The specific steps are:

终端设备确定当前接收到的信号的总强度与预设时间内平均信号强度的差值不大于第一阈值时，按现有实现。When the terminal device determines that the difference between the total strength of the currently received signal and the average signal strength within a preset time is not greater than the first threshold, the existing implementation is followed.

步骤102，该终端设备向基站发送本终端设备在接收下行数据的频带的相邻频带有干扰的通知，使基站在下次调度该终端设备时，将本终端设备调度在距离所述相邻频带大于第二阈值的频带上接收下行数据。Step 102, the terminal equipment sends to the base station a notification that the terminal equipment is receiving interference in the adjacent frequency band of the downlink data frequency band, so that the base station schedules the terminal equipment at a distance greater than or equal to the adjacent frequency band when scheduling the terminal equipment next time. The downlink data is received on the frequency band of the second threshold.

本步骤中基站在调度本终端设备时，具体距离所述相邻频带的距离，即第二阈值，根据实际应用确定，以达到干扰在可接受范围内。In this step, when the base station schedules the terminal equipment, the specific distance from the adjacent frequency band, that is, the second threshold, is determined according to the actual application, so as to keep the interference within an acceptable range.

终端设备通过PUCCH信令实现时，在上行PUCCHformat2/2a/2b中携带干扰指示，所述干扰指示用于标识本终端设备接收下行数据的频带的相邻频带有干扰。When the terminal device implements it through PUCCH signaling, the uplink PUCCH format2/2a/2b carries an interference indication, and the interference indication is used to identify the adjacent frequency band interference of the frequency band where the terminal device receives downlink data.

The frequency band interference notification enables the base station to schedule the device to receive downlink data on a frequency band whose distance from the adjacent frequency band is larger than the second threshold when scheduling the device next time.

较佳地，Preferably,

发送单元202，具体用于所述向基站发送本终端设备在接收下行数据的频带的相邻频带有干扰的通知时，在上行PUCCHformat2/2a/2b中携带干扰指示，所述干扰指示用于标识本终端设备接收下行数据的频带的相邻频带有干扰。The sending unit 202 is specifically configured to send an interference indication to the base station when the adjacent frequency band of the terminal equipment receives downlink data frequency band interferes, and carries an interference indication in the uplink PUCCH format2/2a/2b, and the interference indication is used to identify The adjacent frequency band of the frequency band where the terminal equipment receives downlink data has interference.

较佳地，所述干扰指示携带在PUCCHformat2/2a/2b中的最后一个比特，或第一个填充比特。Preferably, the interference indication carries the last bit in PUCCH format2/2a/2b, or the first padding bit.
