Abstract
In a TDMA/TDD communication system and method, communication throughput is increased by allowing direct duplex communication between the mobile stations that are within close proximity of each other. The system and method determines the range of the mobile stations from each other. Based on the range, the communication units may communicate with each other in one of either direct mode or indirect mode. If an in-range condition is determined, the mobile stations engage in direct duplex communication with each other. Otherwise, they communicate with each other in the indirect mode.
