COMMON CONTROL CHANNEL UPLINK POWER CONTROL FOR ADAPTIVE MODULATION AND CODING TECHNIQUE

摘要

PROBLEM TO BE SOLVED: To provide a power control that minimizes the interference introduced by an uplink common control channel.

SOLUTION: In a method and a system using wireless digital 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 in which the base station measures up link interference on all time slots received from user equipment UE and determines the need for uplink control channel. The base station transmits to the UE the allocation of specific uplink control channels indicating uplink interference in the time slot and potentially the quality margin. The UE determines an appropriate uplink power level based on a path loss determination made by the UE, uplink interference and an optionally selected quality margin. The UE then initiates an uplink communication responsive to these determinations.
