METHOD AND APPARATUS FOR COMMUNICATING DOWNLINK AND UPLINK SUB-FRAMES IN A HALF DUPLEX COMMUNICATION SYSTEM |
摘要 |
<p>The present invention relates to a method for communicating downlink and uplink sub-frames between a base station and at least one half duplex user equipment in a half duplex communication system. The method is characterised in that a scheduled synchronisation time (T"<SUB>STUL</SUB>) is such that the beginning of the reception of the effective part of said uplink sub-frame (UL) is separated from the end of the transmission of the effective part of said first downlink sub-frame (DLl) by a duration which is equal to the difference between a single idle period (IP) and an incremental timing advance value (?t<SUB>A</SUB>), said single idle period (IP), having a duration greater than or equal to the summation of a downlink/uplink required minimum idle duration (T<SUB>DLUL</SUB>) and a uplink/downlink required minimum idle duration (T<SUB>ULDL</SUB>), is reserved in either the end of said first downlink sub-frame (DL<SUB>1</SUB>), or the beginning of said uplink sub-frame (UL), or both, said incremental timing advance value (?t<SUB>A</SUB>) being greater than or equal to said uplink/downlink required minimum idle duration (T<SUB>ULDL</SUB>) and lower than or equal to the difference between the duration of said single idle period (IP) and said downlink/uplink required minimum idle duration (T<SUB>DLUL</SUB>).</p> |
