Location-based bidirectional user scheduling and mode selection in full-duplex system

摘要

This paper studies the bidirectional user scheduling and mode selection in single-cell full-duplex (FD) system, where a FD base station (BS) serves multiple uplink and downlink half-duplex (HD) users. Due to the existence of the inter-user interference from an uplink transmitting user to a downlink receiving user, the system operating in FD mode does not necessarily outperform HD mode, depending on the pairing of the bidirectional users. Different from existing studies based on perfect inter-user channel state information, we design the bidirectional user scheduling and mode selection based on imperfect location information of users. Simulation results show the gain of the proposed schemes over HD system.
