20090300537 | Method and system for changing format for displaying information on handheld device - A method and system for changing a display format for information rendered on a handheld device based at least in part on a velocity of the handheld device recognizes that when the velocity of the handheld device that is optimally held by a stationary user in both hands in a horizontal orientation exceeds a predetermined threshold, it is generally indicative that the handheld device is being held by a mobile user in one hand in a vertical orientation. Accordingly, upon determining that the velocity of the handheld device exceeds the predetermined threshold, information rendered on the handheld device is reoriented from a landscape orientation to a portrait orientation so that the information is oriented correctly from the perspective of the mobile user. Thereafter, upon determining that the velocity of the handheld device is below the predetermined velocity threshold, the information rendered on the handheld device is reoriented from the portrait orientation to the landscape orientation so that the information is oriented correctly from the perspective of a stationary user. | 12-03-2009 |

20100144366 | Methods and systems for determining the location of a femtocell - A femtocell acquires its geographic location using location samples reported by mobile devices that are communicatively coupled with the femtocell. The estimated location may be calculated as an arithmetic mean of reported location samples, a weighted mean of reported location samples, or by using reported location samples in conjunction with estimated distances and trilateration. The estimated location may be applied in geographic license checks, network interference checks and/or emergency call registration, for example. | 06-10-2010 |
20100322185 | SYSTEMS AND METHODS FOR COMPONENT CARRIER SELECTION IN A WIRELESS COMMUNICATION SYSTEM - The present disclosure relates to component carrier (CC) selection in a wireless communication system. A user equipment (UE) that is in idle mode may receive a reference signal (RS) from an evolved Node B (eNB), obtain signal quality measurements with respect to the RS, and switch to a new CC based on the signal quality measurements. For a UE that is in connected mode, an eNB may obtain uplink channel condition information corresponding to uplink CCs, obtain downlink channel condition information corresponding to downlink CCs, and select a CC pair for the UE to use based on the uplink channel condition information and the downlink channel condition information. | 12-23-2010 |
20100323753 | SYSTEMS AND METHODS FOR PROVIDING A REDUCED POWER AMPLIFIER TRANSMISSION MODE - A user equipment (UE) that supports multiple antenna transmission via multiple power amplifiers may operate in a reduced power amplifier (PA) mode. When operating in the reduced PA mode, a subset of the UE's power amplifiers are used to transmit uplink signals. A UE may send a preference signal to an e-Node B to request that the UE operate in the reduced PA mode. | 12-23-2010 |
20110081898 | DETERMINING WHETHER SYSTEM INFORMATION CAN BE REUSED AND MANAGING SYSTEM INFORMATION IN A WIRELESS COMMUNICATION SYSTEM - The present disclosure relates to determining whether system information can be reused and managing system information in a wireless communication system. A wireless communication device may read and compare a physical cell identity and specific system information of a target component carrier with the physical cell identity and specific system information of a source component carrier to determine whether generic system information needs to be read or can be reused. A base station may determine whether a change in system information impacts generic system information and specific system information. The base station may update a data control variable such that it is synchronized for particular sets of component carriers. | 04-07-2011 |
20110270984 | MODIFIED ACCESS CLASSES FOR MACHINE TYPE COMMUNICATION (MTC) DEVICES DURING EMERGENCIES - A method for determining whether to attempt to attach to a network by a machine type communication (MTC) device is described. A triggering event is detected. A radio frame is received from a base station. The radio frame includes a current access class of the base station. The radio frame is the first radio frame to include the current access class after the triggering event. It is determined if the MTC device has access privileges to the base station. It is then decided whether to attempt to attach to a network based on if the MTC device has access privileges. | 11-03-2011 |
