Abstract

The invention provides a space division multiple access resource scheduling method, device and wireless communication system, wherein the method comprises: spatial isolation degree measuring step of obtaining spatial isolation parameter between mobile terminals; system resource scheduling step of realizing system resource multiplexing between mobile terminals, based on spatial isolation parameter between mobile terminals; if the spatial isolation parameter between mobile terminals can not satisfy requirement, the system resource between mobile terminals can be divided, therefore the space division multiple access resource can be scheduled.

Description

technical field [0001] The present invention relates to a wireless communication system, in particular to a space division multiple access resource scheduling method, device and wireless communication system. Background technique [0002] Spatial Division Multiple Access (SDMA, Spatial Division Multiple Access) is usually closely related to smart antenna technology. Based on the antenna array, the smart antenna uses the spatial characteristics of signal transmission and digital signal processing technology to realize the weight vector estimation and downlink beamforming according to the spatial distribution of signals, interference and noise, that is, to form the main beam in the desired useful signal direction , to suppress interference and noise in other directions, including forming nulls in certain interference directions. [0003] According to the spatial propagation characteristics of different mobile terminal signals, space division multiple access uses space selecti...
