Mitigation of interference due to peer-to-peer communication

摘要

Techniques for mitigating interference due to peer-to-peer (P2P) communication are described. In an aspect, a P2P UE may measure the signal strength of downlink signals from base stations and may set its transmit power based on (e.g., proportional to) the measured signal strength in order to mitigate interference to WWAN UEs communicating with base stations. In another aspect, the P2P UE may measure the signal strength of uplink signals from WWAN UEs and may set its transmit power based on (e.g., inversely proportional to) the measured signal strength in order to mitigate interference to the WWAN UEs. In one design, the P2P UE may measure the signal strength of an uplink signal from a WWAN UE, estimate the pathloss between the two UEs based on the measured signal strength, and determine its transmit power based on the estimated pathloss.

1. A method for wireless communication, comprising:
measuring signal strength of at least an uplink signal from a first user equipment (UE) at a second UE, wherein the first UE communicates with a base station and the second UE communicates peer-to-peer with a third UE; and determining transmit power of the second UE based on the measured signal strength of at least the uplink signal from the first UE, wherein the determining the transmit power of the second UE comprises estimating pathloss between the first UE and the second UE based on the measured signal strength of the at least one uplink signal from the first UE, and determining the transmit power of the second UE based on the estimated pathloss.
