Embodiment Construction

[0044] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] The invention provides a downlink antenna selection method of a distributed base station. The distributed base station has two forms. The first form is composed of a baseband processing center and a number of remote radio frequency modules; the second form is composed of a base station coordination group. In the base station coordination group, a base station is responsible for the baseband central processing. The downlink antenna selection method of the distributed base station provided by the present invention is implemented based on the above-mentioned distributed base station. For example, the downlink antenna selection method of the distributed base station provided by the present invention can be executed by the above-mentioned baseband processing center, or by the above-mentioned center responsible for b...

Abstract

The invention discloses a method for selecting a downlink antenna of a distributed base station. The method for selecting a downlink antenna of a distributed base station includes: determining the antenna currently receiving an uplink signal; and calculating the determined quality of the uplink signal received by each of the antennas parameters; selecting a downlink antenna from the determined antennas according to each of the quality parameters. The invention also discloses a downlink antenna selection device of a distributed base station. The present invention can select the downlink antenna according to the quality parameter of the uplink signal, realizes the adaptive selection of the downlink antenna, and realizes the flexible selection of the downlink antenna and the cooperative transmission of the downlink, improves the spatial freedom of the downlink transmission, and further improves the information Transmission quality and rate.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a downlink antenna selection method and device for a distributed base station. Background technique [0002] With the development of LTE and 5G technologies, distributed base stations are increasingly used. Distributed base stations are generally equipped with multiple antennas. When the uplink antenna receives a signal, the downlink antenna corresponding to the uplink antenna is determined according to the preset one-to-one correspondence between the uplink antenna and the downlink antenna. The defect of the prior art is that The downlink antenna is not selected according to the quality of the uplink signal, resulting in inappropriate selection of the downlink antenna, and even poor information transmission quality and low rate. Contents of the invention [0003] The main purpose of the present invention is to provide a downlink antenna selection method...
