METHOD AND SYSTEM FOR DYNAMIC ADJUSTMENT OF DOWNLINK/UPLINK ALLOCATION RATIO IN LTE/TDD SYSTEM
Abstract:
A method and system for dynamic adjustment of downlink/uplink resource allocation ratio in a long-term evolution (LTE) time division duplex (TDD) system is disclosed. The method includes replacing at least one uplink subframe in a subframe pattern with at least one of a mute subframe and a mute uplink pilot timeslot (UpPTS), within a geographical guard area that isolates at least two areas having different TDD allocation patterns. The method further includes scheduling an uplink transmission from at least one mobile terminal such that the at least one of the mute subframe and the mute UpPTS are unused. A simple solution or a TDD configuration index substitution solution, or any combination thereof, may be used to control the uplink transmission involving a mute subframe or a mute UpPTS.
