  • Patent number: 9686815
    Abstract: Access terminals are adapted to facilitate discontinuous transmission (DTX). According to one example, an access terminal determines to disable DTX, such that a continuous reverse link transmission may occur, in a fashion such as not to interfere with the operation of a Frame Early Termination operation utilized in CDMA 1× technology. As one example, the access terminal may cease the utilization of DTX in accordance with a performance metric of a wireless communication network. The performance metric may be a forward link power control setpoint of a base station, a number of quasi-orthogonal function sets being utilized at the base station, a number of frame erasures corresponding to a forward link transmission from the base station, or any other suitable measurable parameter of the network performance. Other aspects, embodiments, and features are also claimed and described.

  • Patent number: 9485727
    Abstract: 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.

  • Publication number: 20130308562
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with improving antenna selection for a UE as part of an access procedure. In an example, a UE with two or more antennas is equipped to obtain receive chain measurements for the two or more antennas associated with the UE when an access procedure is initiated, select an antenna, of the two or more antennas, for transmission based on receive chain measurements for use during at least a portion of the access procedure, and perform the access procedure using the selected antenna. In another example, the UE is equipped to determine that an Access procedure is to be initiated, select an antenna from the two or more antennas based on a selection algorithm, and perform the Access procedure based using the selected antenna. Other aspects, embodiments, and features are also claimed and described.

  • Patent number: 8589715
    Abstract: A method and system for correcting timing errors due to thermal changes within a portable computing device are disclosed. The system and method may include calculating an estimate of frequency for a first clock compared to a second clock. The first clock may comprise a crystal oscillator while the second clock comprises a system clock. Next, a sleep state may be calculated for a hardware device, such as radio access technology (“RAT”) module, based on the estimate of frequency for the first clock. An error in the frequency of the first clock that may occur during the sleep state of the hardware device may be calculated. Subsequently, a magnitude of time that corresponds to an actual length of the sleep state relative to the second clock may be calculated so that an internal clock of the hardware devices may be synchronized with the second clock.
