<P>PROBLEM TO BE SOLVED: To enable distributed schedulers in an enhanced uplink system to allocate uplink transmission resources while preemptively managing intercell interference levels. <P>SOLUTION: In some embodiments, each cell's base station transmits a downlink reference signal at a known transmission power level. A mobile station monitors the received signal strength of the downlink reference signals from multiple base stations. The received signal strength levels can be used by the mobile station to estimate the amount of intercell interference that the mobile station's uplink transmission causes, and the mobile station's uplink transmission parameters are adjusted accordingly. In further embodiments, the received reference signal power levels, or values derived therefrom, are transmitted by the mobile station to its serving base station, where a scheduling algorithm uses the information to adjust one or more transmission parameters relating to a grant of uplink transmission resources to a UE, thereby controlling the intercell interference generated by the mobile station's uplink transmissions. <P>COPYRIGHT: (C)2012,JPO&INPIT |
