Abstract: Apparatus and methods for low power sensing of wireless access technologies are disclosed. In particular, a mobile wireless device, such as an access terminal, may utilize a lower power circuitry portion that operates at a lower power than active circuitry, such as a primary transceiver. The lower power circuitry portion includes a configurable searcher that is capable of sensing if signals of one or more various wireless access technologies are present. When the wireless device utilizes sleep or idle modes for power savings, use of the lower power sensing circuitry to sense the presence of wireless access technologies, rather than using an awoken higher power primary transceiver for sensing, affords increased power savings. An added ability of the lower power circuitry to be put into sleep or idles modes achieves even greater power savings.

Abstract: A method, an apparatus, and a computer program product for communication within a wireless terminal. The method can be implemented using dedicated logic and managed and controlled by state machines and/or sequencers. Data received or provided in a memory of a first integrated circuit of a terminal is encoded and transmitted in a data packet to a second integrated circuit. A header identifying the data type and providing a destination is included in the data packet. The destination may be identified as a memory address memory of the second integrated circuit that is mapped to a corresponding memory address of the first integrated circuit at which the data is received. In an aspect, the apparatus receives a header, detects an error in the received header, determines a failure to identify a packet boundary when the error is detected, and performs a search operation to identify the packet boundary.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which PAPR for an input of an AGC in a wireless receiver is generated. The AGC may provide a gain-controlled signal to a correlator when the PAPR of the input does not exceed the threshold ratio and may clamp the gain of the gain-controlled signal when PAPR of the input is large. A large PAPR may cause termination of search for a signal of interest in a current channel. The search may be resumed in a non-adjacent channel.
