Abstract:
1. A method for transmission power control of a user equipment in a wireless time division duplex communication system using code division multiple access, the method comprising: measuring an interference level; determining a pathloss estimate; determining a long term average of pathloss estimates; and multiplying a first weighting factor, α, by the determined pathloss estimate, producing a weighted pathloss estimate; multiplying (1−α) to the determined long term average of pathloss estimates, producing a weighted long term pathloss estimate; providing a target signal to interference ratio; updating the target signal to interference ratio using outer loop power commands; and determining a transmission power level of the user equipment by adding the weighted pathloss estimate to the weighted long term pathloss estimate to the measured interference level to the updated target signal to interference ratio to a constant value.
