Abstract
A method communicating downlink and uplink sub-frames between a base and at least one half duplex user equipment. For a scheduled synchronization time, beginning of reception of an effective part of the uplink sub-frame is separated from end of transmission of an effective part of the first downlink sub-frame by a duration of the difference between a single idle period and an incremental timing advance value. The single idle period, having a duration greater than or equal to summation of downlink/uplink and uplink/downlink required minimum idle durations, is reserved in the end of the first downlink sub-frame or the beginning of the uplink sub-frame, or both. The incremental timing advance value is greater than or equal to the uplink/downlink required minimum idle duration and lower than or equal to the difference between the duration of the single idle period and the downlink/uplink required minimum idle duration.
