    Abstract: An uplink transmission power control method and a user equipment are provided, where the method includes: determining, by a UE, whether uplink channels are simultaneously transmitted over adjacent subframes between multiple carriers; where the adjacent subframes between the multiple carriers are partially overlapped; and timing advance values of the multiple carriers are different; and if uplink channels are simultaneously transmitted over adjacent subframes between multiple carriers, processing, by the user equipment, an uplink channel transmitted over the last symbol on a partially overlapped subframe of another carrier except a carrier having the greatest timing advance value, so that total transmission power of the uplink channels is lower than the maximum transmission power or an interference level of the user equipment.

    Abstract: Embodiments of the present invention disclose a method and an apparatus for determining an active time of UE, where the method includes: acquiring extension information of a DTX active time of a base station; and adjusting a DTX active time of the UE according to the extension information, and using an overlapped time between the DTX active time of the UE and a DRX active time of the UE as an active time of the UE for listening on a PDCCH channel. The UE can learn a latest DTX condition according to a change of the DTX on a base station side in a manner of acquiring extension information of a DTX active time of the base station, and therefore can determine a correct active time of the UE with reference to DRX of the UE, thereby ultimately ensuring QoS of the UE.

    Abstract translation: 本发明的实施例公开了一种用于确定UE的活动时间的方法和装置，其中所述方法包括：获取基站的DTX活动时间的扩展信息; 以及根据所述扩展信息调整所述UE的DTX活动时间，并且使用所述UE的所述DTX活动时间与所述UE的DRX活动时间之间的重叠时间作为所述UE用于监听PDCCH信道的活跃时间。 UE可以以获取基站的DTX活动时间的扩展信息的方式，根据基站侧的DTX的变化来学习最新的DTX条件，因此可以参考地确定UE的正确的活动时间 到UE的DRX，从而最终确保UE的QoS。
