The invention discloses a
spatial multiplexing link scheduling method applied to a
millimeter wave WPAN. The method includes the following steps that firstly, a
signal detection
broadcasting period in which interference is directionally measured is set before time slot allocation of a current
signal transmission frame is started; secondly, a co-channel mutual interference statistical table of links is established; thirdly, allowed link interference tolerance values of the links are calculated, and a link interference tolerance table is established; fourthly, according to the number of the links, the current
signal transmission frame is divided into multiple time slots corresponding to the links one by one, each link serves as a main link in the corresponding time slot, and other links allowed simultaneous transmission to be conducted except for the main links are determined in the corresponding time slots according to the method that actual interference values among the links are compared with the interference tolerance values of the links. According to the link scheduling method, all the links can be connected in the same transmission period, fairness of the links is guaranteed to a certain degree,
spatial multiplexing gains are utilized to the maximum degree, priority is given to the links which slightly interfere with the main links to enter the corresponding time slots, each time slot can contain the parallel links as many as possible, and
system throughput is maximized.
