Abstract
The present invention relates to methods for performing uplink scheduling of packet data when using adaptive antennas. In the solution according to the invention the uplink scheduling information is transmitted in an antenna beam towards the mobile for which the scheduling information is intended and by allocating mobile stations with similar position to the same packet data channel. All other data packets are transmitted in an antenna beam towards the mobile station for which the data are intended. By adopting the proposed solution it is possible to efficiently use adaptive antennas in a system carrying e.g. GPRS/EGPRS traffic. The carrier to interference gain introduced by adaptive antennas produces a pronounced increase in system performance.
