FIELD: radio engineering, communication.
SUBSTANCE: according to an aspect, P2P UE may measure the signal strength of downlink signals from base stations and may set its transmission power based on (e.g., proportional to) the measured signal strength in order to mitigate interference for WWAN UE communicating with base stations. According to another aspect, the P2P UE may measure the signal strength of uplink signals from WWAN UE and may set its transmission power based on (e.g., inversely proportional to) the measured signal strength in order to mitigate interference for the WWAN UE. According to one version, the P2P UE may measure the signal strength of an uplink signal from WWAN UE, estimate the path loss between the two UE based on the measured signal strength, and determine its transmission power based on the estimated path loss.
EFFECT: mitigating interference due to peer-to-peer communication.
