Abstract

The present invention provides a base station, a radio-frequency (RF) remote unit, and a motherboard, an RF daughter card, and a channel automatic establishment method thereof. The RF remote unit comprises an RF daughter card and an RF remote unit motherboard. An RF device on the RF daughter card realizes an RF channel. An intermediate-frequency (IF) resource pool on the RF remote unit motherboard is provided with multiple RF processing devices realizing an RF channel by means of combination. The RF daughter card and the RF remote unit motherboard can be detachably connected through a card slot. A processor on the RF remote unit motherboard can select, according to an RF daughter card currently connected in the card slot and current service configuration information, an RF daughter card required to be used, and select an IF processing device from the IF resource pool to realize an IF channel corresponding to the RF channel realized by the RF daughter card.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a base station, a radio remote unit and its main board, a radio frequency daughter card and a channel self-building method. Background technique [0002] The base station is an indispensable part of the wireless communication network. At present, the base station is generally composed of a baseband processing unit (Building Base band Unit, BBU) and a radio remote unit (Radio Remote Unit, RRU). At the same time, with the business The scene continues to expand, and the form of base stations such as low-power blind filling also appears. In the form of these base stations, there is a relatively fixed feature, that is, the radio frequency devices such as power amplifiers on each radio frequency channel are integrated on the single board, and the intermediate frequency processing devices corresponding to all radio frequency devices are also solidified, so Once the board is formed...
