COMMUNICATION SYSTEM FOR SUPPORTING CARRIER AGGREGATION AND METHOD AND APPARATUS FOR UPDATING SYSTEM INFORMATION THEREOF

摘要

A communication system for supporting carrier aggregation and a method and apparatus for updating system information thereof are disclosed. A method for providing system information in the communication system supporting carrier aggregation includes: when system information of said communication system changes, generating first information including information for indicating the change of system information; determining a first cell of a terminal related to the change of system information, wherein said first cell is one of cells to which said terminal connects, and corresponds to a carrier unit currently used by said terminal for keeping connection with a base station of said communication system; and transmitting said first information to said terminal through said first cell.

主权项

1. An electronic device, comprising
circuitry, configured to generate a first information comprising updated system information of a dependent carrier; allocate the first information to a dedicated channel for a user equipment; and control transmission of the first information in the dedicated channel via a first cell associated with an independent carrier which is being used by the user equipment to kept in connection with the electronic device, wherein the dependent carrier has fewer channels than the independent carrier and the dependent carrier is aggregated with the independent carrier for transmission.
