Abstract: PROBLEM TO BE SOLVED: To minimize interference introduced by an uplink common control channel.SOLUTION: There is provided a method and system employing a wireless code-division multiple access technology in which adaptive modulation and coding is utilized in order to achieve improved radio resource utilization and provide increased data rates for user services, where a base station measures uplink interference on all time slots received from mobile terminals UEs and determines the need for uplink control channels.

The UE determines an appropriate uplink power level on the basis of a path loss determination made by the UE, the uplink interference and optionally the quality margin. The UE then initiates uplink common control transmission responsive to these determinations.
