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.

摘要： A power calibration scheme adjusts power levels of network of femtocells based on macro signals seen at different points in and around a coverage area and based on the mutual positions of the femtocells (e.g., based on femtocell signals seen at these points). The power calibration scheme thus facilitates a good balance between providing a desired level of coverage and mitigation of interference to nearby macrocells and femtocells.

摘要： 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.

摘要： 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.

A method described herein includes identifying a neighboring macrocell and a time division multiplexing (TDM) channel offset of the neighboring macrocell, the channel offset corresponding to at least one of a signaling channel or an overhead channel; selecting a local channel offset that differs from the channel offset of the neighboring macrocell; and generating a transmission schedule such that first transmissions are omitted for at least a portion of transmission intervals of the neighboring macrocell; wherein the transmission intervals of the neighboring macrocell are identified according to the channel offset of the neighboring macrocell and wherein the first transmissions include at least one of pilot transmissions, medium access control (MAC) transmissions or traffic transmissions.

摘要： An access point (e.g., a femto cell) that is connected in an active call with an access terminal may cooperate with that access terminal or another access terminal to derive timing information from one or more neighboring access points (e.g., macro access points). In addition, an access point may cooperate with an idle access terminal to derive timing information from one or more neighboring access points. For example, an access terminal may determine the difference between pilot transmission timing or frame transmission timing of a femto cell and a macro cell, and report this timing difference to the femto cell. Based on this timing difference, the femto cell may adjust the timing and/or frequency of its transmissions so that these transmissions are synchronized in time and/or frequency as per network operation requirements.
