  • Patent number: 9743414
    Abstract: Methods and apparatus for improved utilization of air link resources are discussed in wireless communications systems employing multi-sector base stations and wireless terminals with multiple antennas. Timing synchronization is maintained across the base station sectors, and the same set of tones are used in adjacent sectors. In a sector boundary region, which is typically a high interference region, a wireless terminal is set to a sector pair state and operated in a MIMO mode of operation, communicating with two adjacent base station antenna faces of the same base station concurrently, the two different adjacent base station antenna faces corresponding to different adjacent sectors. Thus, typically high interference sector boundary regions, are converted into high capacity regions by having the sectors coordinated and utilizing MIMO techniques.

  • Patent number: 9301264
    Abstract: 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.

    Abstract: A method and apparatus for adjusting the transmission power of signals transferred by at least one home base station through a wireless interface to a mobile device, the at least one home base station being located in the cell of a base station. The transmission power is adjusted by first performing an inter cell interference coordination procedure including determining at least one high interference reference zone for the at least one home base station. Then the signal transmission power adjustment for the at least one home base station is determined to ensure a given outage probability that a given function g representing the mobile terminal performance degradation is lower than or equal to a threshold value in the high interference reference zone around the at least one home base station.
