Abstract

Embodiments of the present invention provide a beam selection method and a base station. The method includes: separately acquiring multipath information of each receiving port in M ​​receiving ports, where the multipath information is used to indicate at least one path corresponding to each receiving port; Multi-path matching, to determine i group of matching paths; according to the uplink signals of i group of matching paths, respectively determine the equivalent signals on the N sending ports of the base station; according to the energy of the equivalent signals on the N sending ports, determine the A downlink transmit beam that sends signals to user equipment. In the embodiment of the present invention, the equivalent signal on the transmitting port is determined according to the uplink signal of the matching path between the receiving ports, and the downlink transmitting beam is determined according to the energy of the equivalent signal on the transmitting port, so that the system using AAS can be realized The selection of the downlink transmit beam in .

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a beam selection method and a base station. Background technique [0002] At present, wireless communication operators increasingly hope to introduce technologies such as new carriers and multiple antennas, and at the same time urgently need to improve the situation of limited antenna space. In this context, the application of Active Antenna System (AAS) in the field of wireless communication has become a research hotspot, and the deployment of AAS will be able to solve the above problems of operators. Compared with traditional antennas, AAS has the advantages of high networking flexibility, environmental protection, better system capacity and coverage. [0003] In a system using AAS, multi-sector networking can be performed in the downlink direction, that is, more sectors can be formed through beam splitting, thereby increasing system capacity. For example, by sp...
