Abstract: A system and a method minimize power consumption, signalling overhead, and processing load in blind scheduling in a mobile communication system. A User Equipment (UE) detects a type of an uplink (UL) grant while it is periodically allocated the UL grant. If there is no data to transmit using the UL grant, the UE determines whether to transmit a padding Medium Access Control (MAC) Protocol Data Unit (PDU) to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB) using the UL grant according to the type of the UL grant.

Abstract: Method for radio communication with base station, by user equipment (UE), apparatus in UE for radio communication with base station, a method for radio communication with a UE by a base station, and an apparatus in a base station for radio communication with a UE are provided. The method for radio communication with a base station, by a UE, includes identifying whether an uplink resource for data to be transmitted to the base station is available, when a buffer status report to be transmitted to the base station is triggered; transmitting an uplink packet including the buffer status report using the uplink resource, in response to the uplink resource being available; and transmitting a scheduling request to the base station, in response to the uplink resource not being available for a predetermined time duration, wherein the scheduling request is used for requesting an uplink resource for the buffer status report.

Abstract: A method and an apparatus for supporting a discontinuous reception (DRX) operation in a Node B in a mobile communication system are provided. The method includes defining a second System Frame Number (SFN) where one cycle of a first SFN corresponds to one bit, transmitting information on the second SFN to a User Equipment (UE), determining a second SFN which is used to transmit a paging signal to the UE, determining a first SFN which is used to transmit the paging signal in the determined second SFN, and transmitting the paging signal to the UE at the determined first SFN.

Abstract: Methods and apparatuses are provided for operating a base station in a wireless communication system. Capability information on an aggregation operation using a first RAT and a second RAT, is received from a terminal. A first message including a SSID of an access node and information on an authentication for the access node, is transmitted to the terminal. A second message for requesting to allocate a resource of the second RAT, is transmitted to the access node. First data is transmitted to the terminal by using on the first RAT and second data is transmitted to the terminal via the access node by using the second RAT, after the terminal performs an association and the authentication with the access node based on the SSID and the information on the authentication. The base station supports the first RAT. The access node supports the second RAT.

Abstract: The present disclosure relates to a method and device for receiving a multimedia broadcast multicast service (MBMS) in a mobile communication system. The method for receiving the MBMS of a terminal in the mobile communication system according to an embodiment of the present disclosure is characterized in that it includes: determining whether service area ID (SAI) information on a serving cell is broadcast during the MBMS; receiving the SAI information on the serving cell when it is determined that the SAI information is broadcast; determining, by using the received SAI information of the serving cell, whether an SAI of the MBMS matches the SAI of the serving cell; and changing the cell reselection priority of the frequency of the serving cell to the highest priority if it is determined that the SAI of the MBMS matches the SAI of the serving cell.
