Abstract: Apparatus and methods are disclosed for generating and managing a set of sectors, the signals received from which are utilized to generate an interference estimate for use by an interference cancellation circuit. The set of sectors generally includes a subset of the combined set of sectors in the Active Set and the Candidate Set for an access terminal. A finger of a receiver at an access terminal can be assigned to each sector in the set of sectors for interference cancellation to improve receiver operations. Other aspects, embodiments, and features are also claimed and described.

Abstract: Apparatus and methods, in several embodiments, are disclosed for generating and managing a set of sectors, the signals received from which are utilized to generate an interference estimate for use by an interference cancellation circuit. The set of sectors generally includes a subset of the combined set of sectors in the Active Set and the Candidate Set for an access terminal. A finger of a receiver at an access terminal can be assigned to each sector in the set of sectors for interference cancellation to improve receiver operations.

Abstract: Apparatus and methods are disclosed for selecting between a Rake receiver and an interference cancellation engine (ICE) for receiving forward link signals in a wireless communication network. Selection can be based on one or more of various factors in the channel. These factors can include an average SINR of at least one of the first receiver or the second receiver, a dispersion of a downlink channel, a flatness metric, a number of locked fingers at the first receiver or the second receiver, or a size of an Active Set. Other aspects, features, and embodiments are claimed and described.

Abstract: Access terminals are adapted to regulate power in wireless receiver circuits. In one example, access terminals include a communications interface with at least one wireless receiver circuit. A processing circuit coupled with the communications interface can determine that data is not expected to be received by the access terminal for a period of time while operating in a connected mode. One or more components of the wireless receiver circuit, including a low noise amplifier (LNA) of the wireless receiver circuit, can subsequently be powered down (e.g., set to a passive state) in response to such a determination. Other aspects, embodiments, and features are also claimed and described.
