Method and system for selecting the most suitable logic channel for transmitting packet data in a third generation cellular communications system enables a radio network controller (102) to set bit rate, spread factor and frames required from information supplied by user equipment (104) and the node B's (110) comprising the system. Such information comprises queue size, reported by the user equipments, and noise rise measurements due to user equipment activity, reported by the node B's. The invention advantageously allows a logic channel to be chosen based on the prevailing system state conditions. Hence performance of the system is optimised.
