Apparatus and method of ULTPC rejection threshold optimization in WCDMA for power control algorithm 2

摘要

Techniques for uplink transmit power command (ULTPC) rejection threshold optimization in WCDMA for power control algorithm 2 (PCA2) are described. Uplink transmit power control commands may be received on a five-slot interval. The uplink transmit power control commands may be decoded for each of the five slots. The decoded uplink transmit power control commands may be compared for each of the five slots to a threshold. The threshold may be optimized to minimize overall transmit power control decision error. A bit decision may be made for each of the five slots based on the comparison and an overall transmit power control command may be determined based on the bit decision for each of the five slots over the five-slot interval.

1. A method for controlling transmit power at a user equipment, comprising:
receiving uplink transmit power control commands on a five-slot interval; decoding the uplink transmit power control commands for each of the five slots; comparing the decoded uplink transmit power control commands for each of the five slots to a threshold, wherein the threshold is optimized to minimize overall transmit power control decision error by determining the threshold to prioritize a reduction in transmit power control command determination errors as compared to a reduction in rejections of transmit power control commands; making a bit decision for each of the five slots based on the comparison; and determining an overall transmit power control command based on the bit decision for each of the five slots over the five-slot interval.
