Abstract:
A method for performing uplink scheduling of packet data in a mobile communication system that includes at least one base station transmitting to a plurality of mobile stations within its respective area of coverage, the at least one base station using adaptive antennas, the method comprising:determining the relative positions of each mobile station in the plurality of mobile stations, allocating mobile stations with similar positions to the same adaptive antenna beam, allocating mobile stations located in the same adaptive antenna beam to the same packet data channel, if a downlink packet contains information for more than one of mobile stations, prioritizing the transmission of information by: transmitting data blocks carrying scheduling information from the base station in a first narrow antenna beam towards a mobile station for which scheduling information is intended; and transmitting all other data blocks in a second narrow antenna beam towards a mobile station for which user data in the other data blocks are intended.
