Problems solved by technology

[0002] At present, the remote radio unit (RRU) in the field is designed in the form of different frequency and non-mutual assistance, that is, it can only receive wireless signals in fixed frequency bands, and cannot receive wireless signals in other frequency bands. Therefore, the existing RRU The uplink coverage of the Long Term Evolution (LTE) system is poor, especially when the outfield network is congested, which will lead to unbalanced uplink and downlink

Abstract

The invention discloses a radio frequency front end system and a base station. Uplink signals of more antennas are received, and the receiving of the uplink signals of multiple channels, multiple frequency bands, and multiple carriers is realized, and in addition, an uplink coverage capability of an LTE system is improved. The radio frequency front end system comprises a splitter-combiner and a radio frequency receiver. The splitter-combiner comprises N channels, and each channel is connected with one antenna, and is used to receive the radio frequency signals of the corresponding antenna, and the antennas connected with the channels are different. The radio frequency receiver comprises N receiving links, and each link is connected with each channel, and is used to receive the radio frequency signals from the corresponding channel, and is used to process the received radio frequency signals, and in addition, N is a positive integer greater than or equal to two.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a radio frequency front-end system and base station. Background technique [0002] At present, the remote radio unit (RRU) in the field is designed in the form of inter-frequency non-mutual assistance, that is, it can only receive wireless signals in a fixed frequency band, and cannot receive wireless signals in other frequency bands. Therefore, the existing RRU includes The long term evolution (Long Term Evolution, LTE) system has poor uplink coverage, especially when the external network is congested, it will cause the problem of unbalanced uplink and downlink. Summary of the invention [0003] The embodiments of the present invention provide a radio frequency front-end system and a base station to receive uplink signals of more antennas, realize the reception of multi-channel, multi-frequency, and multi-carrier uplink signals, and improve the uplink coverage capabilit...
