1. A method for receiving information in a mobile terminal of a mobile communication system, the method comprising:
- receiving, by the mobile terminal from a base station via a first portion of a subframe, control information via a shared downlink control channel for a specific logical channel,wherein the control information includes indication information indicatingthat the specific logical channel is a broadcast control logical channel (BCCH) or a paging control logical channel (PCCH), andthat system information corresponding to the specific logical channel will be transmitted via a control message via a shared downlink data channel, the control message being a system information control message or a paging information control message respectively corresponding to the BCCH and the PCCH,wherein the control information further includes scheduling information for the control message, the scheduling information including information about where a radio block (RB) of the shared downlink data channel containing the system information corresponding to the specific logical channel will be located in a domain of time and frequency; and
receiving, by the mobile terminal from the base station via a remaining portion of the subframe, the system information via the shared downlink data channel based on the received scheduling information and indication information,wherein the first portion of the subframe and the remaining portion of the subframe are contiguous portions of the subframe, andwherein the indication information comprises a logical channel identifier.

Abstract
In a wireless mobile communications system, a method for processing control information allows the operations of a mobile terminal to be simplified and permits efficient use of resources for the mobile terminal. The network instructs in advance, the transmission of control information, such as system information and the like, via a single indicator channel. The mobile terminal receives this single indicator channel and uses the indicator information that was transmitted via the indicator channel in order to receive the control information.
