METHOD AND APPARATUS FOR PERFORMING UPLINK TRANSMISSION IN A WIRELESS COMMUNICATION SYSTEM

摘要

A method for and apparatus for transmitting uplink transmission in a wireless communication system supporting multiple carriers is provided. A wireless device transmits the uplink transmission via an alternative Primary serving cell or Secondary serving cell in uplink between the UE and the eNB. Herein the uplink transmission is configured by enabling information with corresponding serving cell as the Primary serving cell or the Secondary serving cell for the uplink transmission. And then, a PUCCH and/or PUSCH can performed on the enabling serving cell and/or cells in consideration of power control more accurately and efficiently.

1. A method for transmitting uplink transmission in a wireless communication system supporting multiple carriers, performed by a wireless device, the method comprising:
receiving enabling information for the uplink transmission, transmitting a set of uplink channels via a first serving cell based on the enabling information, and transmitting another set of uplink channels via the first serving cell or a second serving cell based on the enabling information; wherein the first serving cell or the second serving cell for the uplink transmission is changed alternatively based on the enabling information, and the set of uplink channels each includes at least one of a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH).
