    摘要: A method of uplink packet scheduling in a wireless mobile communications system and method of supporting the same are disclosed, scheduling efficiency can be enhanced in case that one base station schedules uplink packet transmission to a user equipment which is in soft handover with a plurality of base stations. A method of uplink packet scheduling, which is for a user equipment in a soft handover state in a wireless mobile communications system, includes the steps of transmitting a NACK signal in response to an uplink packet transmitted from the user equipment, receiving instruction information for a reception result of the uplink packet in at least one base station from the user equipment or at least one different base station, and performing the uplink packet scheduling for the user equipment by considering the instruction information.

    摘要: A reference signal transmission method in a downlink MIMO system is disclosed. The downlink MIMO system supports a first UE supporting N transmission antennas among a total of M transmission antennas (where M>N) and a second UE supporting the M transmission antennas. The method includes transmitting, by a base station (BS), subframe-associated information which designates a first subframe in which data for the first UE and the second UE is transmitted and a second subframe in which data only for the second UE can be transmitted within a radio frame having a plurality of subframes, and transmitting the first subframe and the second subframe. Reference signals corresponding to antenna ports ‘0’ to ‘N−1’ of the N antennas are mapped to the first subframe, and reference signals corresponding to antenna ports ‘0’ to ‘M−1’ of the M antennas are mapped to the second subframe.
