US 2015/0103779 A1 · METHOD AND APPARATUS FOR CONTROLLING CARRIER FREQUENCY IN MULTI-CARRIER/CELL SYSTEM

Abstract

A method and an apparatus for controlling a carrier frequency in a multi-carrier/cell system are provided. The method includes receiving Channel Quality Indicator (CQI) information of a carrier frequency reported by a terminal, determining whether to deactivate or activate the carrier frequency according to the CQI information, and instructing the terminal to deactivate or activate the carrier frequency according to a result of the determining. Thus, a certain carrier frequency is flexibly activated or deactivated in the multi-carrier/cell system through carrier frequency quality reporting and threshold comparison.

Claims20

Dependent claims

A base station configured to be applied in a multi-carrier/cell system, the base station comprising:

a controller configured to determine to activate or deactivate a subsidiary carrier frequency of the multi-carrier/cell system according to a parameter associated with the subsidiary carrier frequency;
and
a transmitter configured to transmit, to a terminal, an activation/deactivation instruction to activate or deactivate the subsidiary carrier frequency, the activation/deactivation instruction being carried through a Media Access Control (MAC) control element.

Dependencies are inferred from the claim text.
