20130273915 | METHOD AND APPARATUS FOR EXPEDITED WIRELESS DEVICE HANDOVER - The present disclosure presents a method and apparatus for expedited mobile device handover that include performing one or more handover tasks in parallel that have previously been performed exclusively in serial. For example, the disclosure presents a method for wireless device handover, which may include acquiring a target cell, ascertaining a system frame number (SFN) of the target cell, calculating a connection frame number (CFN) for a dedicated channel (DCH) transmission, and reconfiguring a dedicated physical channel (DPCH) based on the calculated CFN. In addition, such an example method may include, while performing at least one of the ascertaining of the SFN, the calculating of the CFN, and the reconfiguring of the DPCH, contemporaneously performing at least one of establishing a downlink dedicated physical channel (DL-DPCH), establishing a synchronization with the target cell, and establishing an uplink dedicated physical channel (UL-DPCH) subsequent to the downlink synchronization. | 10-17-2013 |
20140169246 | DEVICES AND METHODS FOR FACILITATING DYNAMIC POWER REDUCTION DURING DISCONTINOUS RECEPTION - User Equipments (UEs) are adapted to facilitate power conservation by dynamic selection of power reduction techniques during discontinuous reception (DRX), where the power reduction techniques are selected based on a DRX gap length. UEs may be adapted to calculate a DRX gap length, and identify a power reduction technique associated with the determined DRX gap length. The identified power reduction technique may be applied to a receiver circuit during the DRX gap. Other aspects, embodiments, and features are also included. | 06-19-2014 |
20150057046 | System and Methods for improving Page Decode Performance During Reading of System Information on a Multi-SIM Wireless Communication Device - Methods and devices are disclosed for enabling improved performance for page decodes on a SIM of a multi-SIM wireless communication device in which a shared radio frequency (RF) resource is used to read system information for a different SIM. After determining that a first SIM is using the shared RF resource to decode SIBs, the wireless device may receive information about an upcoming page decode time for monitoring a paging channel associated with the second SIM. The wireless device may obtain system information block (SIB) scheduling information associated with the first SIM, and may create a RF resource release gap during the system information read period based on the SIB scheduling information and the upcoming page decode time. Control of the RF resource may be released from the modem stack associated within the first SIM, and gained by a modem stack associated with the second SIM during the RF resource release gap. | 02-26-2015 |
20150063313 | METHOD AND APPARATUS FOR IMPROVING UPLINK PERFORMANCE AT A USER EQUIPMENT - The present disclosure presents a method and apparatus for improving uplink (UL) performance at a user equipment (UE). For example, the method may include identifying a random access channel (RACH) preamble failure when the UE is communicating with a current serving cell of the UE, increasing transmission power of successive RACH preambles based at least on the identifying, comparing signals received on a downlink at the UE via a first path and a second path from the current serving cell of the UE, and determining that a RACH preamble failure problem exists at the UE based at least on the comparing of the signals received on the downlink and identifying of successive RACH preamble failures. As such, improved performance uplink (UL) performance at a UE may be achieved. | 03-05-2015 |
