Embodiment 1

[0028] See figure 1 In this embodiment, a method for controlling carrier pilot transmission is provided, including:

[0029] 101: Know the current traffic load of three sectors in a cell; the three sectors include the first sector, the second sector, and the third sector;

[0030] 102: Determine whether the current service loads of the three sectors are all less than a first threshold;

[0031] 103: If yes, send corresponding control commands to the power amplifiers of each sector, so that the power amplifiers of each sector can time-share or synchronously send the carrier signal within the preset time, the control command Including the pilot transmission start time of the power amplifier carrier of each sector, the frame transmission duration of the power amplifier carrier of each sector, and the frame transmission period of the power amplifier carrier of each sector The number of time slots.

[0032] The first sector, the second sector, and the third sector in this embodiment can a...

Embodiment 2

[0048] This embodiment provides a method for controlling carrier pilot transmission, which can be applied to a GSM base station. In order to realize this method, the base station transmission channel control hardware should have the functions of controlling inter-sector synchronization or time division transmission, variable transmission period and variable transmission frame length. See figure 2 , The method in this embodiment specifically includes:

[0049] 201: Know the current traffic load status of the user channels of the three sectors.

[0050] In this embodiment, the traffic load status of the current user channel of the three sectors of the cell is calculated, so as to know the traffic load status of the current user channel of the three sectors.

[0051] In this embodiment, the three sectors include the first sector, the second sector, and the third sector. The first sector, the second sector, and the third sector can all be the three sectors of the cell. Any sector in d...

Embodiment 3

[0075] This embodiment provides a method for controlling carrier pilot transmission. In the second embodiment, the VODS time-sharing transmission method is used. In this embodiment, the time-division transmission method is not used, but the synchronous transmission method is used, that is, 3 The sectors send continuous or discontinuous frames in the same cycle at the same time, and the number of time slots sent in a frame can still be adjusted with changes in traffic load.

[0076] In this embodiment, if the current traffic loads of the three sectors are all less than the first threshold, the base station switching to the VODS transmission mode specifically includes: transmitting to the power amplifier of the first sector and the second sector respectively The power amplifier of the third sector and the power amplifier of the third sector send a fourth control command, and the frame transmission duration of the fourth control command is equal to the duration of the preset time. T...

Abstract

Disclosed are a method and device for controlling carrier pilot transmission, which belong to the technical field of communications. The method comprises: learning the current service loads of three sectors in a cell, the three sectors comprising a first sector, a second sector and a third sector; judging whether all the current service loads of the three sectors are less than a first threshold value; and if yes, separately sending a corresponding control command to a power amplifier of each sector so that the power amplifier of each sector sends carrier signals asynchronously or synchronously within a preset time, the control command comprising the start time of the carrier pilot transmission of the power amplifier of each sector, the carrier frame transmission duration of the power amplifier of each sector, and the time-slot number in the carrier frame transmission cycle of the power amplifier of each sector.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular, to a method and device for controlling carrier pilot transmission. Background technique [0002] At present, the focus of energy conservation and emission reduction of mobile operators is how to reduce the energy consumption of wireless networks and minimize OPEX costs. In the existing mobile network, the energy consumption of the wireless access part usually accounts for about 75% of the total energy consumption of the entire network. Among them, the power consumption of the main base station equipment accounts for about 55%, and the rest is the power consumption of the equipment room supporting equipment. In the main equipment, the power consumption of the radio frequency power amplifier accounts for more than 40%, so reducing the power consumption of the power amplifier is an effective way to reduce the power consumption of the main equipment. [0003] In order to ...
