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 method for enabling an active hand-in from a macro base station network to a femtocell network includes servicing an active hand-in of a mobile entity from a macro base station to a femtocell network, using a first femtocell of the femtocell network. The active hand-in includes a hard handoff of the mobile entity from the macro base station with soft handoff of the mobile entity enabled between the first femtocell and one or more neighboring femtocells in the femtocell network. The hard handoff with soft handoff enabled may be implemented using novel procedures implemented by one or more entities of a wireless communications network including the femtocells and macro base station.

摘要： An access point is identified based on a plurality of pilot signatures. Here, in addition to transmitting a pilot signal that is encoded (e.g., spread/scrambled) using a particular pilot signature, an access point transmits a message that includes at least one indication of at least one other pilot signature. For example, an access point may use one PN offset to generate a pilot signal and transmit a message that identifies at least one other PN offset. An access terminal that receives the pilot signal and the message may then generate a pilot report that identifies all of these pilot signatures. Upon receiving a handover message including this pilot-related information, a target network entity with knowledge of the pilot signatures assigned to that access point may then accurately identify the access point as a target for handover of the access terminal.

摘要： Methods and apparatuses are provided that facilitate providing access point measurements to restricted access points. Restricted access points can lessen restrictions to allow devices to register with the restricted access point for providing measurements thereto. Additionally or alternatively, access point measurements can be provided to a minimization of drive tests (MDT) server for providing to the restricted access points. Thus, restricted access points can obtain the access point measurements for performing enhanced interference management or other functionality based at least in part on the measurements.

摘要： Techniques for enhanced backhaul flow control are provided. In an exemplary embodiment, a backhaul control system is described that comprises a base station controller (BSC), a backhaul network, and a base transceiver station (BTS). Each is responsive to data and messaging transmitted and received. In one aspect, the BTS includes a queue and a controller. The amount of data in a queue is adjusted by a controller based upon calculating a target queue size value. The controller non-uniformly adjusts the amount of data in a queue based upon a target queue size value which is based upon communication system parameters. The target queue size and amount of data in a queue is adjusted so as to reduce buffer underrun, decrease system latency, and increase communication system throughput.
