Abstract

The invention provides a correction method of power authorization of an E-DCH physical uplink channel (E-PUCH). The method comprises the following steps: determining time slots in which a plurality of the E-PUCHs are located in a current transmission time interval (TTI), wherein a plurality of the E-PUCHs are scheduled for UE; selecting a first type of the time slots possessing the single E-PUCH and a second type of the time slots possessing a plurality of E-PUCHs from the time slots; for any time slot in the first type of the time slots, when a power sum of all carrier waves in the time slot is greater than a largest power authorization of the UE, recording the single E-PUCH in the time slot and performing down-regulation to emission power of the single E-PUCH; for any time slot in the second type of the time slots, when the power sum of all the carrier waves in the time slot is greater than the largest emission power of the UE, recording the time slot and determining priorities of a plurality of E-PUCHs in the each time slot which is recorded, and successively performing the down-regulation to the emission power of a plurality of E-PUCHs in the each time slot. By using the method of the invention, an efficiency of power authorization correction can be increased and a communication quality can be guaranteed.

Description

technical field [0001] The present invention relates to a correction method for power authorization of an enhanced dedicated channel physical uplink channel (E-DCH Physical Uplink Channel, referred to as: E-PUCH), which belongs to the multi-carrier (Multi-carrier, referred to as: MC) high-speed uplink packet access method. into (High Speed ​​Uplink Packet Access, referred to as: HSUPA) technical field. Background technique [0002] In the MC HSUPA technology, a base station (NODEB) may simultaneously schedule multiple carriers of a user equipment (abbreviated: UE) within the same transmission time interval (Transmission Time Interval, abbreviated: TTI). On the UE side, there is at least one time slot occupied by each E-PUCH that may be scheduled to the UE within the TTI, and the sum of the power of all carriers in this time slot is greater than the maximum transmit power of the UE. type of time slots, the power authorization of E-PUCH located in these time slots needs to be...
