Abstract: At least one feature pertains to a method of communication that comprises aligning a measurement task that utilizes a resource within a user equipment, such that at least a portion of the measurement task is performed during a time that the resource is enabled in the user equipment, and executing the measurement task during the time that the resource is enabled in the user equipment. In one example, the measurement task may be a searcher task, the resource may comprise receiver circuitry, and the time that the resource is enabled corresponds to a DRX monitoring interval of a downlink channel, such as a high speed shared control channel. By aligning and executing the searcher task during the time that the resource is enabled in the user equipment, searcher overhead may be reduced. Reducing searcher overhead allows the user equipment to save power by disabling the receiver circuitry.

Abstract: Techniques for performing searches by a user equipment (UE) equipped with multiple receive antennas are described. In an aspect, the UE may support multiple receive diversity (R×D) search modes. Each R×D search mode may be different from each remaining R×D search mode in how correlation is performed, how correlation results are combined, and/or how search results are reported for the multiple receive antennas. The UE may select an R×D search mode from among the multiple R×D search modes and may perform at least one step of a search in accordance with the selected R×D search mode. In another aspect, the UE may perform a search with interference cancellation to detect cell(s). The UE may determine multiple complex weights for multiple receive antennas such that signals from interfering cells can be attenuated. The UE may perform a search to detect cell(s) using the complex weights.

Abstract: A particular method includes transmitting a message corresponding to a reporting event detected at a mobile device, where the reporting event is associated with a network condition that decreases a likelihood of the mobile device successfully decoding a reply to the message. The method also includes, in response to transmitting the message, increasing a signal-to-interference ratio (SIR) target of the mobile device.
