20140018022 | System and Method for Quickly Power Amplifier Control - Embodiments of the present invention provide a system and method for power amplifier control. Before a fixed gain amplifier is disabled and after an automatic gain controller adjusts gain for the last time, a reference transmit power value is read from the automatic gain controller. A gain level is read from the fixed gain amplifier. The reference transmit power value and the gain level are saved in a storage module. Before the fixed gain amplifier is enabled and after the automatic gain controller adjusts gain for the last time, the reference transmit power value saved in the storage module is written into the automatic gain controller and the gain level saved in the storage module is written into the fixed gain amplifier. | 01-16-2014 |
20140056197 | METHOD AND APPARATUS FOR ADJUSTING WAKE-UP PERIOD OF A TERMINAL IN A COMMUNICATIONS SYSTEM - A method and apparatus for adjusting a wake-up period of a terminal in a communications system. In at least one embodiment, the method includes: determining whether a network-side device retransmits a paging message in an area in which the terminal is located; and if a paging message is retransmitted, acquiring a time interval at which the paging message is retransmitted and the number R of times that the paging message is retransmitted, and adjusting the wake-up period of the terminal to a value equal to N times the time interval at which the paging message is retransmitted, wherein N is an integer and 2≦N≦R. Consequently, when a network-side device has the performance of retransmitting a paging message in the current location area, the terminal does not need to wake up according to a DRX period set by the network side, thereby reducing electric energy consumption of the terminal and extending the standby time. | 02-27-2014 |
20140057631 | CELL RESELECTION METHOD AND MOBILE TERMINAL - Embodiments of the present invention provide a cell reselection method and a mobile terminal. In the embodiments of the present invention, whether a cell where signal measurement needs to be performed exists is determined according to a neighboring cell list and a reselection prohibited list; if a cell where signal measurement needs to be performed exists, signal measurement is performed on the cell where signal measurement needs to be performed and a current serving cell to obtain a measurement result; and if the measurement result satisfies a trigger condition of cell reselection, cell reselection is triggered. Therefore, when cell reselection needs to be performed, signal measurement is no longer performed on a cell in the reselection prohibited list and unnecessary signal measurement and cell reselection are avoided, thereby decreasing power consumption of a mobile terminal and prolonging standby time of the mobile terminal. | 02-27-2014 |
