Abstract:
PROBLEM TO BE SOLVED: To define transmit power (e.g., maximum transmit power) on the basis of the maximum received signal strength allowed by a receiver and a minimum coupling loss from a transmitting node to a receiver.SOLUTION: For the transmit power, a corresponding outage created in a cell (e.g., a macro cell) is limited while providing an acceptable level of coverage for access terminals associated with an access node (e.g., a femto node). An access node may autonomously adjust its own transmit power on the basis of channel measurement and a defined coverage hole to mitigate interference. The transmit power may be defined based on channel quality. The transmit power may be defined based on a signal-to-noise ratio at an access terminal. The transmit power of neighboring access nodes may also be controlled by inter-access node signaling.

PROBLEM TO BE SOLVED: To provide a method for reducing RF interference in a wireless network.SOLUTION: Interference that occurs during wireless communication may be managed by using partial reuse and other technique. In some aspects, the partial reuse relates to HARQ interlace, portions of a time slot, frequency spectrum, and extended code. The interference may be managed by using a transmit power profile and/or an attenuation profile. The interference also may be managed by using power management-related technique.
Abstract:
PROBLEM TO BE SOLVED: To provide a method and apparatus for managing, by subframe time reuse, interference that occurs during wireless communication.SOLUTION: Transmission gating in a home access point is adjusted by determining a first gating sequence from a first unplanned access point. A second gating sequence is selected based on the first gating sequence, where the first and second gating sequences are non-interfering. Signals are transmitted according to the second gating sequence from a second unplanned access point to an associated access terminal.
Abstract:
Interference that occurs during wireless communication may be managed through the use of fractional reuse and other techniques. In some aspects fractional reuse may relate to HARQ interlaces (2202), portions of a timeslot, frequency spectrum, and spreading codes. Interference may be managed through the use of a transmit power profile and/or an attenuation profile. Interference also may be managed through the use of power management- related techniques.

Abstract:
Systems and methodologies are described that facilitate dynamic load balancing in a communications network. In particular, one or more mobile devices can send random access preambles on an uplink frequency paired to a downlink frequency employed to connect the one or more mobile devices to a base station. The base station can determine if an uplink frequency load imbalance exists based upon the random access preambles. The base station can transmit an indicator on an acquisition indicator channel to at least one mobile device wherein the indicator includes a command to transition to a new uplink frequency. The mobile device can switch uplink frequencies in response to the command.
