20150334574 | Preventing Coexistence Interference Through Smart Band Selection in MSMA Devices - Various embodiments leverage the typical manner in which a RAT selects a supported frequency band listed in its acquisition database and the standard communications with its network indicating the supported frequency bands to avoid potential coexistence events with one or more other RATs. In particular, various embodiments include methods for avoiding band interference between RATs operating on a multi-SIM communication device by identifying the frequency bands available to each of the RATs, comparing the identified frequency bands to determine whether any RAT's frequency bands will interfere with one or more other RAT's frequency bands, and in response to determining that there is a possibility of frequency band interference, removing those interfering frequency bands from that RAT's acquisition database. As a result, during standard communications, that RAT will report to its network that it supports only non-interfering frequency bands. | 11-19-2015 |
20150382285 | OTHER RADIO ACCESS TECHNOLOGY SEARCH INSIDE A GSM TUNE-AWAY GAP IN MULTI-SIM DEVICES - A mobile communication device, includes: a radio frequency (RF) receive chain; a control unit configured to tune the RF receive chain to receive signals from one of a first radio access technology (RAT) and a second RAT different from the first RAT; and a first signal modification unit configured to modify the signals received from the first RAT. The control unit is further configured to suspend operation of the first signal modification unit when the RF receive chain is tuned to receive signals on the second RAT. | 12-31-2015 |
20160050644 | METHODS AND APPARATUS FOR QUICK BURST TUNE AWAY IN MULTI-SIM DEVICES - Methods and apparatus for wireless communication are provided.

20160066217 | APPARATUS AND METHOD OF INTELLIGENT RADIO ACCESS TECHNOLOGY RESELECTION IN WIRELESS COMMUNICATIONS - Aspects of the present disclosure relate to a multimode user equipment (UE) that when suffering a power crunch, can intelligently reselect to another RAT to extend the battery life of the UE. The reselected RAT has a lower specified maximum transmit power relative to the currently attached RAT. Therefore, the UE may reduce its battery drain to extend its service time per charge when a call is made utilizing the reselected RAT. The UE intelligently selects the RAT that will likely consume less uplink transmit power to communicate with a base station in order to conserve battery power in a poor coverage area, when the UE is experiencing a power crunch condition. | 03-03-2016 |
20160073349 | Enhanced Device Selection Algorithm for Device-to-Device (D2D) Communication - Methods, systems and devices are provided for selecting one or more target devices for device-to-device (D2D) communication with a device. A device processor may determine whether a battery power level of the device is below a threshold battery power level. The device processor may establish a received power level threshold in response to determining that the battery power level of the device is below a threshold power battery level. The device processor may determine whether a received power level of a signal from target devices for D2D communication is above the received power level threshold. In response to determining that the received power level from a target device is above the received power level threshold, the device processor may permit D2D communication with that target device. | 03-10-2016 |
20160119804 | ADAPTIVE CONTROL CHANNEL DETECTION IN WIRELESS COMMUNICATIONS - Aspects described herein relate to adaptive control channel detection in wireless communications. A signal-to-interference-and-noise ratio (SINR) of a signal received by a receiver comprising multiple sub-receivers is measured, wherein the SINR is filtered according to a signal combining technology. Based at least in part on the SINR, it is determined whether to utilize the signal combining technology in combining signals related to a channel received over the multiple sub-receivers. Accordingly, the signals related to the channel received over the multiple sub-receivers can be demodulated using the signal combining technology based on determining to utilize the signal combining technology | 04-28-2016 |
20160119857 | BILATERAL SEARCH ALGORITHM FOR LTE SYSTEM - Methods, systems, and devices are described for acquiring a network by a user equipment (UE) by concurrently scanning for a network signal on supported frequencies by two or more antennas. In one aspect, a method may include searching by a first antenna for a first signal on a first group of supported frequencies while concurrently searching by a second antenna for the first signal on a second group of supported frequencies.
