With apparent advantages of severalGHz license-free spectra, low power consumption, low-cost implementation ofCMOS devices,\nand so forth, 60GHz wireless communication technology becomes the first choice for short-range high ratewireless communication\nin future wireless personal area network (WPAN) and wireless local area network (WLAN).While different from commonWPAN\nsystem with omnidirectional communication, 60GHz-WPAN system generally adopts directional communication. In this paper,\na device (DEV) interconnected mechanism of 60GHz-WPAN based on switched beamforming technology is structured firstly.\nWithout considering the directional transmission characteristic of 60GHz communication, most of the 60GHz-WPAN Medium\nAccess Control (MAC) protocols fail to make full use of the high spatial reuse degree caused by directional communication.\nIn this paper, an average time slot multiplexing allocation (ATSMA) algorithm based on space/time division multiple access\n(STDMA) solution is proposed, which allows concurrent transmission in a single time slot. The designed link schedule process\nincludes common channel interference (CCI) probing scheme, link coexistence determination scheme, and link schedule algorithm.\nExtensive simulations are conducted in order to demonstrate the efficiency of proposed scheme. Simulation results demonstrated\nthat the capacity gain is obvious using ATSMA algorithm, no matter whether under omnidirectional antenna or under directional\nantenna.
