Abstract

The invention provides an extended carrier power control method and user equipment. The method comprises the following steps of: acquiring power control parameters of an extended carrier, wherein the extended carrier is a carrier attached to an independent carrier; determining the transmitting power of a physical uplink shared channel (PUSCH) of the extended carrier according to the power control parameters of the extended carrier; and transmitting the PUSCH on the extended carrier by employing the transmitting power of the PUSCH of the extended carrier. According to the embodiment of the invention, the related power processing schemes of the extended carrier can be provided.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to an extended carrier power control method and user equipment. Background technique [0002] In a Long Term Evolution Advanced (LTE-A) system, a Carrier Aggregation (Carrier Aggregation, CA) technology is used as a method for expanding system bandwidth to meet its higher bandwidth requirement. In the LTE-A carrier aggregation scenario, a user equipment (User Equipment, UE) supports up to five component carriers (Component Carrier, CC), and the system configures a pair of uplink and downlink primary carriers (Primary Component Carrier, PCC) for the UE, and the remaining carriers A secondary carrier (Secondary Component Carrier, SCC), the primary carrier and the secondary carrier may also be called a primary cell (Pcell) and a secondary cell (Scell), respectively. A physical uplink control channel (Physical Uplink Control Channel, PUCCH) of the UE can only be sent on the up...
