Abstract

The invention relates to a space division multiplexing and MIMO combining method and a base station. The embodiment of the space division multiplexing and MIMO combining method comprises the steps of acquiring the space channel information estimation of each terminal, scheduling priority of the terminal, determining whether the terminal sends a single flow or dual flows according to the acquired space channel information estimation of each terminal, carrying out space division multiplexing scheduling on the user terminal which is not scheduled, has top priority and has greatest isolation with the existing scheduled user, allocating resources to the space division multiplexing user terminal, determining weighting factors of downlink sending data of the user terminal and sending data. With the invention, the space division multiplexing can be combined with the MIMO so as to achieve the effect of effectively utilizing the interference rejection of a smart antenna, and the user throughput and the system capacity can be increased.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a combination method of space division multiplexing and multiple input multiple output and a base station. Background technique [0002] In wireless communication systems, the research and application of smart antenna technology has received more and more attention. The smart antenna uses digital signal processing technology to generate spatially directional beams, so that the main beam of the antenna is aligned with the direction of arrival of user signals, and the side lobes or nulls are aligned with the direction of arrival of interference signals, so as to achieve the purpose of fully and efficiently utilizing mobile user signals and suppressing interference signals . The use of smart antennas can maximize the useful signal and minimize the interference signal, thus greatly improving the system capacity and expanding the coverage of the system. [0003] One a...
