    摘要： Aspects describe communications environments in which femtocell capability is provided to devices within the communications network. 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： 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： Systems and methods for avoiding interference signals sent by a femto node in a wireless communication system are described herein. In one embodiment, the method comprises establishing a communication link between a first transceiver and a base station. The base station is configured to provide wireless communication coverage within a first area. The method further comprises detecting by the first transceiver a femto signal generated by the femto node. The femto node is configured to provide wireless communication coverage within a second area to at least a second transceiver. The second transceiver is different from the first transceiver. The second area is smaller than the first area. The method further comprises identifying information indicative of a signal strength of the femto signal. The method further comprises transmitting a first message in response to detecting the femto signal, the first message comprising information identifying the femto node and the information indicative of the signal strength of the femto signal to the base station over a first frequency carrier. The method further comprises receiving a second message from the base station. The second message comprises information indicative of an instruction to communicate over a second carrier frequency. The method further comprises communicating with the base station over a second frequency carrier in response to the second message.

    摘要： Transmit power for a user equipment (UE) is set by a Home NodeB (HNB) in response to interference at a nearby macrocell. The HNB monitors an interference level to the macrocell from a UE communicating with the HNB. An acceptable transmit power for the UE is determined by the HNB in response to the interference level. A power change indicator is transmitted from the HNB to the UE to adjust the transmit power of the UE. In some cases, the interference may be estimated from a busy indicator from the macrocell and the HNB sends a modified version of the busy indicator to the UE to adjust the transmit power of the UE. In other cases, the HNB estimates a path loss for the UE based on received signal power from the macrocell and signals a transmit power change to the UE, if needed, based on the estimated path loss.

    摘要： 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, 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.
