Abstract: Techniques for sending page messages with quality of service (QoS) in a wireless communication system are described. In an aspect, a network entity receives incoming packets for access terminals operating in an idle state, generates page messages in response to the incoming packets, and includes QoS information in the page messages. The QoS information for each page message may indicate whether the page message is delay sensitive. A base transceiver station (BTS) receives page messages with QoS information and sends the page messages to access terminals based on the QoS information. In one design, the BTS determines whether each page message is delay sensitive based on the QoS information, sends page messages that are delay sensitive, and either sends or delays sending page messages that are delay insensitive in order to reduce the number of packets to send for the page messages.

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.

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: A system and method of conducting wireless communications between a wireless communication device (WCD) and both a first network (e.g., IS-2000) supporting voice and data services and a second network (e.g., IS-856) supporting packet data services. The method comprises providing the WCD with a primary transceiver and a secondary receiver for conducting wireless communications in a spatial diversity for the second network traffic or broadcast; disabling the secondary receiver and spatial diversity before a paging slot or 1x system acquisition and synchronization attempts; tuning the secondary receiver to a first network carrier frequency to perform first network activities; and retuning the secondary receiver to a second network carrier frequency for spatial diversity after performing the first network activities. The first network activities may include pilot set maintenance, overhead message maintenance, page match detection, or 1x system acquisition and synchronization attempts.
