Access terminals are adapted to facilitate reacquisition procedures for a slotted idle mode. According to one example, an access terminal can operate in a slotted idle mode. The access terminal can then determine one or more optimized parameters for reacquisition procedures. In one example, the access terminal can determine an optimized length of time for reacquisition periods by incrementally reducing the length of time for reacquisition periods until an optimized length of time is obtained. In another example, the access terminal can determine an optimized number of pseudorandom noise (PN) signals and PN positions to be stored during each awake state of the slotted idle mode by incrementally reducing the number of PN signals and PN positions that are stored until an optimized number of stored PN signals and PN positions is obtained. Other aspects, embodiments, and features are also included.

Devices and methods for facilitating reacquisition procedures

Techniques for determining if it is safe for a mobile device to transition directly from a traffic session to a paging mode and for avoiding network re-synchronization procedures in stationary M2M devices are disclosed. It may be safe for direct transition if before-call and in-call network parameters correspond. If safe, the mobile device may transition from the traffic session directly to the paging mode to begin immediately monitoring the paging channel. In stationary M2M devices, paging information is stored before the traffic session and, once the traffic session is complete, the M2M device may be configured to receive paging messaging based on the stored paging information. The M2M device may also store system access information and confirm the validity of the information before returning to the sleep state. The stationary M2M device avoids network re-synchronization procedures. Other aspects, embodiments, and features are also claimed and described.

Method and apparatus for avoiding network re-synchronization in stationary M2M devices

Apparatus and methods for optimizing data transmission include receiving an indicator indicating the availability of a first communication channel, the first communication channel having a higher data rate than a second communication channel. Aspects can include determining whether the first communication channel is available to transmit data based on the indicator, and transmitting the data via the first communication channel, upon determining that the first communication channel is available. Additionally, aspects include entering a sleep state, upon determining that the first communication channel is not available, and determining whether the first communication channel has become available during a subsequent awake period. Entering a sleep state and determining whether the first communication channel has become available during a subsequent awake period may occur until the first communication channel becomes available or until an expiration of a timer. Other aspects, embodiments, and features are also claimed and described.

High-speed data channel availability

Various features and aspects of the present disclosure are adapted to facilitate improved reception of page messages at an access terminal operable in a wireless communication system. When the access terminal is in a region where two or more cells overlap, if the access terminal is moving away from the coverage area of an active cell and moving towards the coverage area of a neighbor cell, the access terminal may miss an incoming page message transmitted from its serving cell. Thus, the access terminal may dedicate fingers of a rake receiver to listen to paging information transmitted from one or more neighbor cells, decoding this information if a page decoding operation corresponding to the active cell fails. Other aspects, embodiments, and features are also claimed and described.

Methods and devices for parallel page decoding from neighboring cells

Devices, systems, articles of manufacture, and methods for optimized page matching is disclosed. According to some embodiments, a portion of a sub-slot is read. A page message is extracted from the portion of the sub-slot. A page matching procedure is performed prior to the end of the sub-slot. Other aspects, embodiments, and features are also claimed and described.

Optimized page matching

Methods and apparatus for wireless communication via a communication device (e.g, via a 1X Advanced enabled mobile device) are discussed. Embodiments can include calculating that a temperature associated with the mobile device has exceeded a thermal threshold. Aspects of the methods and apparatus include transmitting a guarantee frame, from each set of frames to be transmitted, when the temperature associated with a mobile device has exceeded the thermal threshold. Aspects of the methods and apparatus include determining that the temperature associated with a mobile device has fallen below the thermal threshold. Aspects of the methods and apparatus also include reactivating normal transmissions upon determining that the temperature associated with the mobile device has fallen below the thermal threshold. Other aspects, embodiments, and features are also claimed and described.
