Abstract: To perform erasure detection for an intermittently active transport channel with unknown format, a receiver determines an energy metric and a symbol error rate (SER) for a received block with CRC failure. The receiver computes uncorrelated random variables u and v for the received block based on the energy metric and SER, the estimated means and standard deviations of the energy metric and SER, and a correlation coefficient indicative of the correlation between the energy metric and SER. The receiver then evaluates the uncorrelated random variables u and v based on at least one decision criterion and declares the received block to be an erased block or a DTX block based on the result of the evaluation. The decision criterion may be defined based on a target probability of false alarm and adjusted based on another metric, such as a zero state bit, for the received block.

Abstract: Apparatus and methods for power control for mitigation or control of interference in a wireless communications environment. Power control techniques can consider the effectiveness of interference cancellation before making power control determinations. For example, where interference with a base station from an interfering wireless terminal is being canceled such that the effects of that interference are not adversely affecting operations of the base station, the offending terminal can be left unchanged, or its transmit power can be increased. On the other hand, where the interference cancellation operation is not able to cancel the effects of the interfering signal sufficiently, the operation can lower the uplink transmit power of the offending signal so as to not cause interference to the other base station.

Abstract: 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.

Abstract: Systems and method for hand-in of mobile users into a local RAN, such as UMTS ERAN, deployment are provided. In accordance with various embodiments, a local RAN gateway is utilized to multicast relocation request messages to multiple target ERANs pursuant to the receipt of a measurement report from a user equipment. By virtue of either a pre-configured relocation request acknowledgement or a pair of generated tokens, each of the multiple target ERANs may allocate the appropriate resources for the user equipment to be handed into one of the multiple target ERANs. In accordance with another embodiment, the local RAN gateway additionally multicasts a user equipment uplink layer configuration to each of the multiple target ERANs. In accordance with yet another embodiment, the local RAN gateway receives the timing difference between a current cell and target cell to disambiguate the target cell and corresponding ERAN.

Abstract: 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.
