摘要
In a wireless digital communication system employing code-division multiple access (CDMA) technology, a method in which adaptive modulation and coding (AM&C) is utilized in order to achieve improved radio resource utilization and provide increased data rates for user services in which the base station measures up link interference on all time slots received from mobile terminals (UEs) and determines the need for uplink control channel; the base station transmitting to the UE the allocation of specific uplink control channels indicating uplink interference in the time slot and potentially the quality margin; the UE determining appropriate uplink power level based on a path loss determination made by the UE, uplink interference and the quality margin; the UE initiating an uplink common control transmission responsive to these determinations.
