Document Type and Number:
WIPO Patent Application WO/2012/081923
Kind Code:
A2
Abstract:
Provided are an apparatus and a method for performing wireless connection re-establishment in a multiple component carrier system. The present description discloses a terminal comprising: a cell selection unit which selects a cell for said wireless connection re-establishment upon occurrence of failure of wireless connection; a sub-serving cell setting information constructing unit which constructs sub-serving cell setting information for specifying at least one sub-serving cell set for the terminal; a message transmitting unit which transmits a wireless connection re-establishment request message for requesting procedures for the wireless connection re-establishment and a wireless connection re-establishment completion message indicating the completion of the procedures for the wireless connection re-establishment, to a base station through the selected cell; and a message receiving unit which receives a wireless connection re-establishment message as a response to said wireless connection re-establishment request message. According to the present invention, RRC connection re-establishment procedures are performed using sub-serving cell setting information, and therefore, change of configuration of the sub-serving cell which has been already set between the terminal and the base station may be performed without exchanging any additional message when the sub-serving cell is added/changed/removed.
