DATA RECEPTION AND TRANSMISSION METHOD AND APPARATUS FOR POWER SAVING IN COMMUNICATION SYSTEM USING MULTIPLE CARRIERS

摘要

The present invention relates to a multi-carrier resource utilization method and apparatus for power saving in a communication system using a multi-carrier, in which the activation of a secondary carrier for transmitting and receiving data traffic between a terminal and a base station is determined according to the QoS (Quality of Service) requirements such as a data traffic status between the terminal and the base station, a maximum sustained traffic rate, a maximum traffic burst size, or the like, and an indication message (Indication) indicating this is transferred to the terminal through a primary carrier to transmit and receive data traffic through the activated secondary carrier.

主权项

1. A method of operating carriers at a user equipment in wireless communication system, the method comprising:
configuring a primary carrier and at least one secondary carrier; receiving a message through the primary carrier, the message information including an indicator indicating activation of the at least one secondary carrier and an index of the at least one secondary carrier; activating the at least one secondary carrier based on the indicator; receiving scheduling information associated with a scheduled secondary carrier of the at least one activated secondary carrier through the primary carrier, the scheduling information including an index of the scheduled secondary carrier and downlink resource assignment information; and receiving data through the scheduled secondary carrier based on the scheduling information associated with the scheduled secondary carrier.
