摘要： A method for managing uplink signal quality at a radio node and at a macrocell and/or external cell, includes determining a first transmit power associated with a radio node of a small-cell radio access network and a second transmit power associated with a macrocell and/or an external cell. A desense value associated with an uplink of the radio node of the small-cell radio access network is provided, which enables balancing of a first signal to noise-plus-interference ratio associated with an uplink of the small-cell radio access network and a second signal to noise-plus-interference ratio associated with an uplink of the macrocell and/or external cell in relation to a downlink of the radio node, thereby managing uplink signal quality at the radio node of the small-cell radio access network and at the macrocell and/or external cell.

摘要： Apparatus and methods for reconfiguration of a communication environment based on loading requirements. Network operations are monitored and analyzed to determine loading balance across the network or a portion thereof. Where warranted, the network is reconfigured to balance the load across multiple network entities. For example, in a cellular-type of network, traffic loads and throughput requirements are analyzed for the access points and their user equipment. Where loading imbalances occur, the cell coverage areas of one or more access points can be reconfigured to alleviate bottlenecks or improve balancing.

摘要： Erasure detection and power control are performed for an intermittently active transport channel with unknown format. A receiver processes each received block and determines whether it passes or fails CRC. For each received block with CRC failure, the receiver performs erasure detection by computing a symbol error rate (SER) and energy of the received block, comparing the computed SER against an SER threshold, comparing the computed energy against an energy threshold, and declaring an erasure if the computed SER is less than the SER threshold and the computed energy exceeds the energy threshold. The SER and energy thresholds may be adjusted based on the average SER and the average energy for prior received blocks with CRC failures. For power control, an SIR target is increased by an UP step whenever an erased block is detected for the transport channel.

摘要： Techniques for achieving linear monotonic output power with piecewise non-linear and/or non-monotonic circuits are described. A coarse gain is selected for a first circuit having non-linear and/or non-monotonic characteristics. A fine gain is selected for a second circuit used to account for output power error due to the coarse gain. First and second look-up tables may store output power versus gain for the first and second circuits, respectively. An output power in the first look-up table may be selected based on the requested output power, and the gain corresponding to the selected output power may be provided as the coarse gain. An output power in the second look-up table may be selected based on the output power error, and the gain corresponding to the selected output power may be provided as the second gain.

摘要： Methods and apparatus are described that enable a deployment of a system of wireless nodes, e.g., femtocells, which can self-configure themselves into a balanced and optimized wireless network. In various embodiments, access points switch between a network monitoring mode in which network monitoring is performed and a communications mode in which the access point serves one or more wireless terminals and communicates traffic data to/from the wireless terminals. Traffic data transmission to wireless terminals are not supported in network monitoring mode. Based on information gathered from one or more access nodes while they operating in network monitoring mode of operation, access point configuration information is generated and one or more access points are automatically configured.
