Abstract: Communication devices configured to identify a channel for network communication are disclosed. For example, an apparatus operable in a wireless communication network can receive a message that specifies a list of channels in operation in a network, remove at least one channel from the list of channels, and identify a channel from among the list of channels other than the at least one removed channel for communication with the network. The apparatus may be able to increase the likelihood that it will acquire the network, even though the network may be utilizing one or more channels that are not supported by the apparatus. Other aspects, embodiments, and features are also disclosed and claimed.

Abstract: Methods and apparatus for selecting one or more suitable antennas for use during power-up/initial acquisition and out of service modes are disclosed. In some examples, initial system acquisition may be performed for a particular receive circuit utilizing a selected one of a first antenna or a second antenna, based on a channel characteristic, such as an automatic gain control (AGC) value corresponding to a received signal energy utilizing either of the antennas. In another example, initial system acquisition utilizing either a receive diversity determination algorithm or an antenna switching determination algorithm may be performed based on a channel characteristic, such as an AGC value corresponding to a received signal energy utilizing one of the antennas coupled to one of the receive circuits.

Abstract: Systems and methodologies are described that facilitate dynamically allocating demodulation resources of a wideband receiver to provide improved demodulation of simultaneously received signals. Signal-to-noise ratio (SNR) and/or packet error rate (PER) can be measured for the plurality of carriers to determine which demodulators related to the carriers require more resources than others to demodulate signals at a specified signal quality. Where the SNR of a related carrier is high and/or PER is low, the demodulator can require fewer resources than where the SNR of a related carrier is low and/or PER is high. In this regard, the resources are dynamically allocated among the demodulators and reallocated where SNR/PER changes and/or additional resources are made available.
