Transmit power control based on receiver gain setting in a wireless communication network

摘要

Techniques for performing transmit power control based on receiver gain setting in a wireless communication network are described. In an aspect, a terminal A may estimate pathloss to another terminal B, e.g., based on a peer discovery signal received from terminal B. Terminal A may then determine a transmit power level for a peer-to-peer (PTP) signal (e.g., a paging signal) based on the estimated pathloss, a receiver gain setting at terminal B, and a target received power level for the PTP signal. Terminal A may send the PTP signal at the determined transmit power level to terminal B. In another aspect, terminal B may use different receiver gain settings in different time intervals to receive PTP signals from other terminals. Terminal A may then select a suitable time interval to send the PTP signal based on the pathloss and the different receiver gain settings used by terminal B.

1. A method for wireless communication, comprising:
receiving a peer discovery signal from a second terminal; estimating pathloss from a first terminal to the second terminal based on a transmit power level and a received power level of the peer discovery signal; determining another transmit power level for a peer-to-peer (PTP) signal based on the estimated pathloss, a maximum value of a receiver gain setting at the second terminal, and a target received power level for the PTP signal at the second terminal, wherein the PTP signal is a paging signal sent by the first terminal to page the second terminal; and sending the PTP signal at the determined transmit power level to the second terminal.
