Abstract: Transmissions by a first access point (e.g., a femto cell) are restricted upon detecting an access terminal in the vicinity of the first access point in the event the access terminal is communicating with a second access point (e.g., a macro cell). Upon detection of such an access terminal, the access terminal restricts transmission (e.g., beacon transmission) on a downlink carrier frequency on which the access terminal is actively receiving information from the second access point. This restriction of transmission by the access point may involve, for example, temporarily reducing transmit power, reducing the periodicity of transmission, or ceasing transmission.

Abstract: A base station in a cellular wireless communications system uses one or more control algorithms to control a transmission pattern of a 1xRTT or DO discovery beacon. The transmission pattern enables access terminals using any one of multiple wake-up periods and wake-up offsets to discover all macrocell frequencies in a finite amount of time. In addition, for base stations allocating a single transmit chain to both 1xRTT and DO beacons, the transmission pattern enables a definite maximum discovery time for both 1xRTT and DO beacons for all access terminals entering the base station coverage.

Abstract: Methods and apparatus are provided for adapting femtocell properties based on changes detected in network topology. A method includes detecting a network topology change associated with a network node. The method includes determining an availability factor of the network node based on the topology change. The method includes setting mobility parameters of at least one mobile entity serviced by the network entity and mitigating interference with at least one neighboring network node based at least in part on the network topology and on at least one adjusted resource parameter of the network entity.
