Abstract

The invention discloses a base station. The base station comprises array antennas and a base band unit BBU. The array antennas comprise n receiving ports. The n is an integer greater than or equal to 3. The array antennas are used for receiving uplink signals through m receiving ports in n receiving ports. The BBU is used for obtaining first uplink signals and second uplink signals, carrying out demodulation according to the first uplink signals and carrying out uplink scheduling according to the second uplink signals. The first uplink signals are the uplink signals received through the m receiving ports. The m is a positive integer greater than q and is not greater than n. The q is the number of the downlink beams of the array antennas. The second uplink signals are the uplink signals obtained by carrying out digital forming on the first uplink signals according to a downlink directional diagram of the array antennas. According to the base station provided by the embodiment of the invention, the utilization rate of the uplink performance of the antennas is improved; the cells in which user equipment are located will not be strongly interfered; and therefore, 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...
