The distance estimation unit is for generating a distance estimation signal responsive to the packets of data received at the remote device such that the distance estimation signal is associated with a power level at which the power level adjustable transmitter is not able to sufficiently transmit the packets of data to the remote device. | 2011-07-14 |
20110170431 | MITIGATION OF INTERFERENCE DUE TO PEER-TO-PEER COMMUNICATION - 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. | 2011-07-14 |
20110170432 | ACCESS POINT TRANSMIT POWER SCHEMES - In a multi-level power transmission scheme, an access point transmits at one power level, while repeatedly transmitting at a burst power level for short periods of time. For example, a femto cell may transmit a beacon with periodic high power bursts of short duration, while the femto cell transmit power also undergoes high power bursts aligned with the beacon bursts. In a network listen-based power control scheme, an access point listens for one or more parameters sent over-the-air by the network and then defines transmit power based on the received parameter(s). In some aspects, beacon transmit power may be set based on a defined outage radius parameter and the total received signal power on a channel. In some aspects, access point transmit power may be set based on a defined coverage parameter and the received energy associated with signals from access points of a certain type. | 2011-07-14 |
