    Abstract: 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.

    Abstract: A femtocell base station includes a transmitter that transmits downlink signals to a mobile station, a receiver that receives uplink signals from the mobile station, a standard transmit pulse-shaping filter, and a narrower transmit pulse-shaping filter that limits the bandwidth of the downlink signals to a greater extent than the standard transmit pulse-shaping filter. The femtocell base station also includes a standard receive pulse-shaping filter and a narrower receive pulse-shaping filter. The femtocell base station is configured to switch between the standard transmit pulse-shaping filter and the narrower transmit pulse-shaping filter, and to switch between the standard receive pulse-shaping filter and the narrower receive pulse-shaping filter. A mobile station may switch from a standard transmit pulse-shaping filter to a narrower transmit pulse-shaping filter to limit uplink interference. A mobile station may switch from a narrower transmit pulse-shaping filter to a standard transmit pulse-shaping filter to achieve a higher data rate.

    Abstract: A mobile station may include a standard transmit pulse-shaping filter, a standard receive pulse-shaping filter, a narrower transmit pulse-shaping filter, and a narrower receive pulse-shaping filter. 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.

    Abstract: Techniques are provided for mobile assisted reverse link interference management. For example, a method for providing mobile assisted reverse link (RL) interference management includes requesting at least one pilot strength measurement from a user device. The method may include receiving at least one macrocell pilot strength measurement or femtocell pilot or beacon strength measurement from the user device in response to the request. The method may include determining a data rate allocation for the user device based at least in part on the at least one macrocell pilot strength measurement or femtocell pilot or beacon strength measurement. The method may include transmitting the data rate allocation to the user device, thereby controlling RL interference caused by the user device to at least one non-serving cell.
