具体实施方式Detailed ways
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有付出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
如图1所示,为现有技术中340M宽带终端和PDT终端的应用场景的一种示例图。该示例中,340M宽带终端占用336~344M频段发送数据,340M宽带终端的功放在351MHz的带外抑制度为≥60dB。由于受限于体积,340M宽带终端无法应用带外抑制度更高的模拟滤波器,因此当PDT终端处在PDT基站覆盖边缘位置,而且340M宽带终端与PDT终端距离很近时,340M宽带终端的邻频泄露信号可能会压制相对较弱的PDT终端的下行信号,导致PDT终端语音质量受损或者无法接入PDT网络。As shown in FIG. 1 , it is an example diagram of an application scenario of a 340M broadband terminal and a PDT terminal in the prior art. In this example, the 340M broadband terminal occupies the 336-344M frequency band to send data, and the out-of-band suppression of the power amplifier of the 340M broadband terminal at 351MHz is ≥60dB. Due to the limited size, the 340M broadband terminal cannot apply an analog filter with a higher degree of out-of-band suppression. Therefore, when the PDT terminal is at the edge of the PDT base station coverage, and the 340M broadband terminal is very close to the PDT terminal, the The adjacent channel leakage signal may suppress the downlink signal of the relatively weak PDT terminal, resulting in the loss of voice quality of the PDT terminal or the inability to access the PDT network.
基于上述问题,本申请提供的方案的基本思想是:由340M宽带终端监测附近是否有PDT终端,以及PDT终端是否在PDT基站覆盖的边缘位置,如果监测到340M宽带终端附近有PDT终端,且PDT终端处在PDT基站覆盖的边缘位置,则对自身的最大发射功率进行限制,和/或,优先使用远离PDT工作频段的频段向340M宽带基站发送上行数据,从而抑制340M宽带终端对PDT终端的干扰。Based on the above problems, the basic idea of the solution provided by this application is: the 340M broadband terminal monitors whether there is a PDT terminal nearby, and whether the PDT terminal is at the edge position covered by the PDT base station, if there is a PDT terminal near the 340M broadband terminal, and the PDT If the terminal is located at the edge of the coverage of the PDT base station, the maximum transmit power of the terminal is limited, and/or the frequency band far from the PDT operating frequency band is preferentially used to send uplink data to the 340M broadband base station, thereby suppressing the interference of the 340M broadband terminal to the PDT terminal. .
基于上述基本思想,请参阅图2和图3,图2为本申请实施例提供的340M宽带终端和PDT终端的应用场景的一种示例图,图3为本申请实施例提供的信号处理方法的一种实现流程图,本申请实施例提供的信号处理方法应用于340M宽带终端中,具体可以包括:Based on the above basic idea, please refer to FIG. 2 and FIG. 3 . FIG. 2 is an example diagram of an application scenario of a 340M broadband terminal and a PDT terminal provided by an embodiment of the present application, and FIG. 3 is a schematic diagram of a signal processing method provided by an embodiment of the present application. An implementation flowchart. The signal processing method provided by the embodiment of the present application is applied to a 340M broadband terminal, which may specifically include:
步骤S31:接收警用数字集群标准PDT的上行工作频段信号和下行工作频段信号。Step S31: Receive the uplink working frequency band signal and the downlink working frequency band signal of the police digital trunking standard PDT.
本申请实施例中,340M宽带终端除了能够收发336~344M频段的信号外,还可以接收PDT的351~366M频段的信号。In the embodiment of the present application, the 340M broadband terminal can not only receive and transmit signals in the 336-344M frequency band, but also receive the signals in the 351-366M frequency band of the PDT.
当340M宽带终端位于PDT基站的信号覆盖范围内,且340M宽带终端附近有PDT终端时,340M宽带终端便可以接收警用数字集群标准PDT的上行工作频段信号(即PDT终端向PDT基站发送的信号)和下行工作频段信号(即PDT基站向PDT终端发送的信号)。When the 340M broadband terminal is located within the signal coverage of the PDT base station and there is a PDT terminal near the 340M broadband terminal, the 340M broadband terminal can receive the uplink working frequency band signal of the police digital trunking standard PDT (that is, the signal sent by the PDT terminal to the PDT base station) ) and the downlink working frequency band signal (that is, the signal sent by the PDT base station to the PDT terminal).
步骤S32:检测PDT的上行工作频段的信号强度(为便于叙述,记为第一信号强度)和下行工作频段的信号强度(为便于叙述,记为第二信号强度)。Step S32: Detect the signal strength of the uplink working frequency band of the PDT (denoted as the first signal strength for ease of description) and the signal strength of the downlink working frequency band (denoted as the second signal strength for ease of description).
步骤S33:若第一信号强度和第二信号强度满足预设条件,限制340M宽带终端的最大发射功率和/或优先使用远离PDT工作频段的频段发送上行数据。Step S33: If the first signal strength and the second signal strength meet the preset conditions, limit the maximum transmit power of the 340M broadband terminal and/or preferentially use a frequency band far from the PDT working frequency band to send uplink data.
本实施例中340M宽带终端接收并检测PDT的上下行工作频段的信号强度可以是周期性的,也可以是事件触发的,都不影响本发明技术方案的实施,故此处不做限制。In this embodiment, the signal strength of the uplink and downlink working frequency bands of the PDT received and detected by the 340M broadband terminal may be periodic or event-triggered, which does not affect the implementation of the technical solution of the present invention, so it is not limited here.
若第一信号强度和第二信号强度满足预设条件,说明340M宽带终端附近有PDT终端,且PDT终端处在PDT基站的信号覆盖区域的边缘位置,此时可以限制340M宽带终端的最大发射功率,或者,340M宽带终端优先使用远离PDT工作频段的频段向340M宽带基站发送上行数据,或者,限制340M宽带终端的最大发射功率并且优先使用远离PDT工作频段的频段向340M宽带基站发送上行数据。If the first signal strength and the second signal strength meet the preset conditions, it means that there is a PDT terminal near the 340M broadband terminal, and the PDT terminal is at the edge of the signal coverage area of the PDT base station. At this time, the maximum transmit power of the 340M broadband terminal can be limited. , or, the 340M broadband terminal preferentially uses the frequency band far away from the PDT working frequency band to send uplink data to the 340M broadband base station, or limits the maximum transmit power of the 340M broadband terminal and preferentially uses the frequency band far away from the PDT working frequency band to send uplink data to the 340M broadband base station.
其中,限制340M宽带终端的最大发射功率是指,限制340M宽带终端的最大发射功率不超过功率阈值,该功率阈值是可以保证不会对PDT终端的通信质量造成影像的最大值。该功率阈值可以通过实验室仿真得到,或者,通过外场实测得到。Among them, limiting the maximum transmit power of the 340M broadband terminal refers to limiting the maximum transmit power of the 340M broadband terminal not to exceed the power threshold, which is the maximum value that can ensure that the communication quality of the PDT terminal will not be affected. The power threshold can be obtained through laboratory simulation, or obtained through field measurement.
优先使用远离PDT工作频段的频段发送上行数据是指,在336-344M频段的可用频段中,优先选用靠近336M的频段发送上行数据,使得340M宽带终端的实际工作频段与PDT工作频段的隔离度尽量大。Preferentially using the frequency band far from the PDT working frequency band to send uplink data means that in the available frequency bands of the 336-344M frequency band, the frequency band close to 336M is preferentially used to send the uplink data, so that the actual working frequency band of the 340M broadband terminal can be isolated from the PDT working frequency band as far as possible. big.
可选的,限制340M宽带终端的最大发射功率和/或优先使用远离PDT工作频段的频段发送上行数据的一种具体实现方式可以为:Optionally, a specific implementation manner of limiting the maximum transmit power of the 340M broadband terminal and/or preferentially using a frequency band far away from the PDT working frequency band to send uplink data may be:
340M宽带终端确定最大发射功率(为便于叙述,记为目标最大发射功率)和/或优先使用的工作频段(为便于叙述,记为目标工作频段),然后向340M宽带基站发送资源申请,该资源申请中携带有目标最大发射功率和目标工作频段,若340M宽带基站在接收到资源申请后反馈确定信息,则将340M宽带终端的最大发射功率和/或优先使用的工作频段调整为目标最大发射功率和/或目标工作频段。若340M宽带基站在接收到资源申请后反馈的不是确定信息,而是调度指示,则将340M宽带终端的最大发射功率和/或优先使用的工作频段调整为调度指示所指示的最大发射功率和/或工作频段。The 340M broadband terminal determines the maximum transmission power (for the convenience of description, denoted as the target maximum transmission power) and/or the working frequency band to be used preferentially (for the convenience of description, denoted as the target working frequency band), and then sends a resource application to the 340M broadband base station. The application carries the target maximum transmit power and the target working frequency band. If the 340M broadband base station feeds back the confirmation information after receiving the resource application, the maximum transmit power of the 340M broadband terminal and/or the preferred working frequency band will be adjusted to the target maximum transmit power and/or target operating frequency band. If the 340M broadband base station feeds back not the determination information but the scheduling instruction after receiving the resource application, then adjust the maximum transmit power and/or the preferentially used working frequency band of the 340M broadband terminal to the maximum transmit power indicated by the scheduling instruction and/or or working frequency.
本申请提供的信号处理方法,340M宽带终端除了可以接收336~344M频段的信号外,还可以接收PDT的351~366M频段的信号,当接收到PDT上行工作频段和下行工作频段信号时,基于PDT的上行工作频段和下行工作频段的信号强度满足预设条件,限制340M宽带终端的最大发射功率和/或优先使用远离PDT工作频段的频段发送上行数据,从而有效抑制340M宽带终端对PDT终端的干扰。基于上述方案,本申请对于340M宽带终端在硬件上的改进是使得340M宽带终端能够接收PDT的351~366M频段的信号,这种改进可以通过增加信号接收侧的滤波通带实现,而这种实现方式几乎可以不增加340M宽带终端的体积。According to the signal processing method provided in this application, the 340M broadband terminal can not only receive the signals in the 336-344M frequency band, but also receive the signals in the 351-366M frequency band of the PDT. The signal strength of the upstream working frequency band and the downstream working frequency band meet the preset conditions, limit the maximum transmit power of the 340M broadband terminal and/or preferentially use the frequency band far away from the PDT working frequency band to send uplink data, thereby effectively suppressing the interference of the 340M broadband terminal to the PDT terminal. . Based on the above solution, the hardware improvement of the 340M broadband terminal in this application is to enable the 340M broadband terminal to receive signals in the 351-366M frequency band of the PDT. This improvement can be achieved by increasing the filter passband on the signal receiving side, and this realization In this way, the volume of the 340M broadband terminal can hardly be increased.

在一可选的实施例中,上述限制340M宽带终端的最大发射功率和/或优先使用远离PDT工作频段的频段发送上行数据的一种实现方式可以为:In an optional embodiment, an implementation manner of limiting the maximum transmit power of the 340M broadband terminal and/or preferentially using a frequency band far away from the PDT working frequency band to send uplink data may be:
向340M宽带基站发送测量报告,该测量报告中携带标识信息,该标识信息用于标识上述第一信号强度和第二信号强度满足预设条件。A measurement report is sent to the 340M broadband base station, where the measurement report carries identification information, where the identification information is used to identify that the above-mentioned first signal strength and second signal strength meet preset conditions.
接收340M宽带基站发送的控制信息,基于控制信息限制340M宽带终端的最大发射功率和/或优先使用远离PDT工作频段的频段发送上行数据。Receive control information sent by the 340M broadband base station, limit the maximum transmit power of the 340M broadband terminal based on the control information, and/or preferentially use a frequency band far from the PDT working frequency band to send uplink data.
也就是说,340M宽带终端的最大发射功率和工作频段由340M宽带基站调度指示。That is to say, the maximum transmit power and working frequency band of the 340M broadband terminal are indicated by the 340M broadband base station scheduling.

At this time, the identification information in the measurement report is used to identify whether the first signal strength and the second signal strength meet the predetermined conditions.
