20130136045 | METHODS AND DEVICES FOR FACILITATING OPTIMIZED GENERAL PAGE MESSAGE MONITORING - Access terminals are adapted to receive a non-empty general page message (GPM) which includes a number of page records that is less than a predefined maximum number of page records. In response to receiving the non-empty general page message (GPM), the access terminal can enter into a sleep state of a slotted idle mode. A method operational on an access terminal includes receiving a general page message (GPM) with at least one page record. A number of page records included in the general page message (GPM) may be determined to be less than a maximum number of page records allowed in the general page message (GPM). The access terminal may enter a sleep state in response to determining the number of page records in the received general page message (GPM) is less than the maximum allowed number of page records. Other aspects, embodiments, and features are also included. | 05-30-2013 |
20130229960 | METHODS AND DEVICES FOR FACILITATING TRANSMITTER CIRCUIT POWER REGULATION - Access terminals are adapted to facilitate power regulation of a transmitter circuit by employing a transmitter power timer. An access terminal may identify expiration of a predetermined period of time without any data to be sent. The access terminal may subsequently power down the transmitter circuit in response to the expiration of the predetermined period of time. Methods for facilitating power regulation of a transmitter circuit include initiating a transmitter power timer after a data transmission, and powering off the transmitter circuit when the transmitter power timer expires without data to be transmitted. The transmitter power timer can be adapted to facilitate guarantee frames for smart blanking, and can operate independent of a dormancy timer. Other aspects, embodiments, and features are also included. | 09-05-2013 |
20130303181 | METHODS AND APPARATUSES FOR DATA THROUGHPUT OPTIMIZATION IN DSDS SCENARIOS - Aspects of the present disclosure provide methods and apparatuses for improved throughput for network subscriptions in multi-SIM, multi-standby wireless devices by altering a tune away frequency to another network subscription based on throughput level or communication link parameters. For example, the present application provides a method of tune away in a wireless system, which includes initiating a data session via a first subscription in a multi-subscriber identity module, multi-standby user equipment, determining that a data rate associated with the data session is less than a threshold data rate value, establishing a modified tune away frequency based on the determining, and tuning a radio resource away to a second subscription based on the modified tune away frequency. Through such operation, throughput on an active subscription in such user equipment can be dynamically maximized. | 11-14-2013 |
20140056191 | METHODS AND DEVICES FOR PROCESSING A GENERAL PAGE MESSAGE IN SLOTTED IDLE MODE - Access terminals are adapted to facilitate power conservation by selectively powering down one or more hardware block when processing a general page message (GPM) received in slotted idle mode. An access terminal may include a processor core, a de-interleaver, a decoder and a firmware block. The firmware block may be adapted to enable the processor core to sleep while the firmware block collects samples of a received transmission and extracts symbols from the collected samples. The firmware block may further power ON the de-interleaver to de-interleave the extracted symbols, and the decoder to decode the de-interleaved symbols. Other aspects, embodiments, and features are also included. | 02-27-2014 |
20140056215 | RAPID NETWORK ACQUISITION AND OVERHEAD MESSAGE STORAGE FOR MACHINE-TO-MACHINE DEVICES - A stationary access terminal, such as a stationary remote sensor, capable of wireless communication with a network is provided. The access terminal obtains sector information associated with a wireless network node by establishing a communication link with the network node. The access terminal then stores the sector information in non-volatile memory, and later retrieves the sector information from the memory, for example, after a subsequent boot up or wake up event. The stored sector information is used by the access terminal to establish a subsequent communication link with the network node, and may include at least one of channel, band, and pseudo-random number sequence information. The access terminal may also store overhead messages received from the network node in the non-volatile memory. The stored overhead messages may later be retrieved to establish system operating parameters of the network node after the subsequent boot up or wake up event. | 02-27-2014 |
20140198695 | APPARATUS AND METHOD FOR AVOIDING SYSTEM LOSSES FOR M2M DEVICES OPERATING AT LONGER SLOT CYCLE - Aspects of the present disclosure are directed to an apparatus and methods capable of pre-correcting reacquisition slew of pilot signal timing when a mobile device operates in a slotted mode or discontinuous reception (DRX) mode. In one aspect, a mobile device is operated in slotted mode. The mobile device wakes up to perform a pilot reacquisition corresponding to a slotted mode and detects a slew of a pilot timing relative to a pilot reference timing. The mobile device adjusts a subsequent pilot reference timing by an amount corresponding to the detected slew, to be utilized during a subsequent wake-up cycle. The mobile device returns to a sleep state to wait for the subsequent wake-up cycle. Other aspects, embodiments, and features are also claimed and described. | 07-17-2014 |
20140198882 | SYSTEMS, APPARATUS, AND METHODS FOR RECEIVING PAGING MESSAGES BY CREATING FAT PATHS IN FAST FADING SCENARIOS - This disclosure provides systems, methods, and apparatus for receiving paging messages in fast fading scenarios. In one aspect, a method of demodulating a paging message during an assigned time slot by a wireless communications apparatus operating in an idle mode is provided. The method includes determining, in anticipation of the assigned time slot, an expected time position corresponding to a path of a pilot signal having a greater signal strength relative to other pilot signals. The method further includes assigning a first demodulation element to demodulate the pilot signal with reference to the expected time position and assigning a second demodulation element to demodulate the pilot signal with reference to a time offset from the expected time position. Other aspects, embodiments, and features are also claimed and described. | 07-17-2014 |
20140221031 | METHOD AND APPARATUS FOR EFFICIENT AND DYNAMIC SYSTEM RESELECTION PROCEDURE FOR M2M STATIONARY DEVICES - Apparatus and method for wireless communication in a wireless communication network include receiving a synchronization channel message parameter at a user equipment (UE) from a network entity. The aspects also include transmitting data to the network entity based on the synchronization channel message parameter. Additionally, the aspects include determining whether an assignment of a reverse supplemental (RS) channel to the UE is performed by the network entity. Still further, the aspects include incrementing a counter value when the network entity fails to assign the RS channel.

20140274019 | METHOD AND APPARATUS FOR AVOIDING NETWORK RE-SYNCHRONIZATION IN STATIONARY M2M DEVICES - 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. | 09-18-2014 |
