    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: Transmissions of beacons by a set of access points (e.g., femtocells) are synchronized to facilitate discovery of the access points by an access terminal moving through the coverage areas of the access points. In some embodiments, periodic beacon transmissions are synchronized across all of the femtocells of a set of femtocells such that each femtocell transmits a beacon signal according to a similar pattern and at the same time. In some embodiments, an opportunistic beacon control scheme involves commencing beacon transmissions by at least one femtocell of a set of femtocells upon determining that an access terminal has communicated with one or more of the femtocells.

A femtocell base station may include a narrower transmit pulse-shaping filter and a narrower receive pulse-shaping filter. The mobile station may utilize the narrower transmit pulse-shaping filter for transmitting uplink signals and the narrower receive pulse-shaping filter for receiving downlink signals when it is receiving service from the femtocell base station. The mobile station may utilize the standard transmit pulse-shaping filter for transmitting uplink signals and the standard receive pulse-shaping filter for receiving downlink signals when it is receiving service from a macrocell base station.

    摘要: A method for reducing interference to wireless communication devices is described. It is determined that a base station is deployed with a first coverage area that overlaps a second coverage area of a femto access point. The base station uses a first carrier for wireless communications. The femto access point uses a second carrier for wireless communications. Transmissions by the femto access point interfere with transmissions by the base station. An amount of radio frequency (RF) leakage experienced by wireless communication devices communicating with the base station is estimated. Interference experienced by the wireless communication devices is minimized.

    摘要: Embodiments disclosed herein relate to methods and systems for server selection during feedback channel impairment in wireless communications. The feedback channel may be provided by a data rate control (DRC) channel, transmitted from an access terminal to an access network relating the selected serving sector (DRC cover) and the desired data rate (DRC rate) for transmission on forward link. During DRC cover erasure (e.g., due to channel impairment), a data source control (DSC) channel may be used as complimentary information to assist the DRC erasure mapping decision at the access network.
