A signal processing method, device and base station

Abstract

Disclosed in the present application is a base station. The base station comprises an array antenna and a baseband processing unit (BBU). The array antenna comprises n reception ports, n being a positive integer greater than 3. The array antenna is used for receiving uplink signals through m reception ports among n reception ports. The BBU is used for obtaining first uplink signals and second uplink signals, performing demodulation according to the first uplink signals and performing uplink scheduling according to the second uplink signals, the first uplink signals being uplink signals received through the m reception ports, m being a positive integer greater than q and is not greater than n, q is the number of downlink beams of the array antenna, and the second uplink signals being uplink signals obtained by performing digital forming on the first uplink signals according to a downlink directional diagram of the array antenna. By implementing the base station provided in the embodiment of the present application, the utilization rate of uplink performance of the antennas is improved; it is ensured that a cell in which a user equipment is located is not be strongly interfered, and accordingly there are available resources for scheduling.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a signal processing method, device and base station. Background technique [0002] The currently widely used multi-sector networking with the same frequency coverage generally adopts multi-column split antennas or Active Antenna System (Active Antenna System AAS). The downlink uses multiple sectors, and the uplink uses up to 2Rx for each sector, that is, Two receiving ports receive, but the actual number of receiving ports of the multi-column antenna is greater than the number of sectors multiplied by 2Rx. For example: Take the four-row antenna as an example, the four-row antenna will have two sectors, so the uplink will use four receiving ports, but in fact, the four-row antenna has 8 receiving ports, so there will be four receiving ports The uplink is idle, therefore, the existing solution does not make the best use of the uplink performance of multiple antennas...
