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

    摘要: A cell reselection parameter is transmitted on one carrier frequency for a defined period of time to cause access terminals operating on that carrier frequency to more aggressively search for access points on at least one other carrier frequency. For example, a femto cell operating on one carrier frequency may transmit a broadcast channel including a cell reselection parameter such as Sintersearch on another carrier frequency that is used by a macro cell. Here, the value of the cell reselection parameter (e.g., Sintersearch) is chosen so that the access terminals will more aggressively conduct inter-frequency searches. In addition, the cell reselection parameter is transmitted for a period of time that ensures that a nearby access terminal will receive the parameter during its wakeup interval.

    摘要: Methods and apparatuses are provided for causing active hand-in of a device from a macrocell base station to a femto node, which can be an inter-frequency hand-in. The femto node can broadcast a beacon over an operating frequency of the macrocell base station, and the macrocell base station, and/or one or more network components, can identify the femto node based on one or more parameters reported by the device from receiving the beacon. The beacon can be transmitted at varying powers to ensure active hand-in triggering, mitigate interference and/or can be powered on and off for such purposes. In addition, a macrocell base station can regulate compressed mode periods during which a device can measure the femto node based on receiving information regarding device proximity to the femto node, or a device can generate proximity indication messages base on measuring the beacon signals, etc.

In some aspects fractional reuse may relate to HARQ interlaces, 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.

A non-femto enabled device and/or a femto enabled device can communicate with a femto enabled device in the same geographical area for femto-enabled peer-to-peer communication. Two non-femto enabled devices can be provided femto functionality through utilization of a femto enabled device, which operates as a hub between the two devices. Other aspects relate to enhanced position determination, adaptive coverage enhancement, local mobile networks, open access femtocells without a backhaul, and local broadcast of media though utilization of femto enabled devices.

    摘要: 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.
