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： A cell reselection parameter is transmitted on one carrier frequency for a defined period of time to cause access terminals operating on that carrier frequency to more aggressively search for access points on at least one other carrier frequency. For example, a femto cell operating on one carrier frequency may transmit a broadcast channel including a cell reselection parameter such as Sintersearch on another carrier frequency that is used by a macro cell. Here, the value of the cell reselection parameter (e.g., Sintersearch) is chosen so that the access terminals will more aggressively conduct inter-frequency searches. In addition, the cell reselection parameter is transmitted for a period of time that ensures that a nearby access terminal will receive the parameter during its wakeup interval.

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： 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.

摘要： Methods and apparatuses are provided that include adaptively configuring a rise-over-thermal (RoT) threshold at a base station to improve communications with one or more devices while mitigating interference to one or more other base stations. A potential device pathloss to the macrocell can be computed based on a measured pathloss thereto applied with a coverage area of the low power base station to emulate a worst-case device, one or more received measurement reports, and/or the like. The RoT threshold can be computed based at least in part on the pathloss and/or a maximum interference level at the macrocell. In addition, the RoT threshold can be adapted based on a reverse link attenuation level.

摘要： An access point transmits cell information via a physical layer channel. In some cases, the cell information sent on the physical layer channel comprises a physical layer identifier. For example, a physical layer channel may be modulated based on a cell identifier and/or a closed subscriber group identifier associated with the access point. Through the use of this cell information, an access point may be quickly identified for mobility and/or interference management operations. In addition, this cell information may be used for finger-printing operations.

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.
