Embodiments of the present invention exploit the reciprocity of radio
channels in TDD, and longer-term correlation between average uplink and
downlink path losses in FDD wireless communication systems to enable
distributed schedulers in an enhanced uplink system to allocate uplink
transmission resources while preemptively managing intercell interference
levels. 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 transmitted and received signal strength levels can be used
by the mobile station to estimate the amount of intercell interference
that the mobile station's uplink transmissions cause, 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 the UE, thereby controlling the
intercell interference generated by the mobile station's uplink
transmissions.
