Embodiment Construction

[0021] In order to make the purpose, technical means and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0022] figure 1 It is a schematic diagram of the basic flow chart of the power adjustment method in this application, such as figure 1 As shown, the method includes:

[0023] Step 101: Determine the first uplink path loss threshold TH1 according to the saturation power of the terminal, the transmit power of the base station and the cell bandwidth; calculate the second uplink path loss threshold TH2 according to the maximum uplink path loss allowed for the terminal.

[0024] The processing of calculating TH1 and TH2 in this step can be performed in advance, and does not need to be recalculated each time whether the power needs to be adjusted. Among them, the first uplink path loss threshold TH1 is related to the saturation power of the terminal, and is used to ...

Abstract

The invention discloses a base station adaptive downlink power adjustment method, which comprises the following steps that: a base station determines a first uplink path loss threshold TH1 according to the saturation power of a terminal, the transmitting power of the base station and the bandwidth of a cell; a second uplink path loss threshold TH2 is calculated according to the allowed uplink maximum path loss of the terminal; the base station periodically calculates current path loss information of each terminal in the cell for the cell; the current path loss information of each terminal is compared with the first uplink path loss threshold TH1 and the second uplink path loss threshold TH2, and if the current path loss information of any terminal is smaller than the TH1 and the current path loss information of no terminal is larger than the TH2, when the transmitting power of the cell is allowed to be reduced, the downlink transmitting power of the cell is reduced; otherwise, the transmitting power of the cell is not changed. By applying the invention, the problem of downlink power saturation in a base station scene can be solved.

Description

technical field [0001] The present application relates to a power adjustment technology in a communication system, in particular to a base station adaptive downlink power adjustment method. Background technique [0002] In current base stations, a fixed transmission power is generally used to transmit downlink signals. However, this downlink transmission method may cause problems for the base station in some cases. [0003] Specifically, in current practical applications, a backpack-type base station appears, which is small in size and can be carried in a vehicle or carried around. For this type of base station, the handheld or CPE terminal may be very close to the base station, but the receiving power of the terminal is limited. In this case, the receiving power of the terminal in the downlink direction may exceed the limit of its own receiving power, resulting in power saturation. cause abnormalities in the business.
