Abstract: An operation method of a terminal that receives a DRS in a mobile communication system operating in an unlicensed spectrum includes: receiving an SS/PBCH block included in the DRS; checking at least one monitoring occasion for a PDCCH for receiving RMSI on the basis of a PBCH included in the SS/PBCH; monitoring the at least one monitoring occasion and detecting the PDCCH for receiving the RMSI; and receiving a PDSCH including the RMSI on the basis of the detected PDCCH, wherein the at least one monitoring occasion is set to at least one symbol among symbols in front of the PDSCH and symbols behind the PDSCH. Accordingly, the DRS and data may be reliably transmitted and received in the mobile communication system operating in the unlicensed spectrum.

Abstract: Provided are methods of managing a terminal in a heterogeneous network (HetNet) environment. Between the methods, a method of managing a terminal performed in a base station includes determining whether or not a measurement change request event has occurred, and when a measurement change request event has occurred, transmitting a control message for instructing a change of a measurement operation to the terminal. Accordingly, it is possible to improve a measurement operation and discontinuous reception (DRX) operation control procedure necessary for connection control between one or more base stations and a terminal in a HetNet environment, and thereby performance of a system can be improved.

Abstract: Provided is a method of transmitting and receiving data using a persistent allocation scheme in order to effectively support a voice service between a base station and a mobile terminal in a packet based mobile communication system. When an error occurs in transmitting control information that indicates whether to use a radio resource using the persistent allocation scheme, the base station may retransmit the control information and thereby maintain a communication quality.

Abstract: Disclosed are a control method for supporting multiple connections in a mobile communication system and an apparatus for supporting multiple connections. In the method for supporting the multiple connections to be performed in first and second base stations, a first base station receives the measured results for multiple connections from a terminal, determines whether the plurality of connections are set on the basis of the measured results, transmits the information for setting the multiple connections to the second base station when setting the multiple results, and the second base station generates the control information for setting the multiple connections of the terminal on the basis of the information for setting the multiple connections received from the first base station. Thus, the multiple connections can be easily supported and the performance of the mobile communication system can be improved therethrough.

Abstract: Disclosed is a carrier management method for use in a carrier aggregation environment of a mobile communication system. In the method, a base station is configured to transmit a deactivation message for a secondary carrier to a terminal and change the secondary carrier to a deactivation state after a predetermined time from the transmission of the deactivation message. The terminal receives the deactivation message transmitted by the base station, and changes the secondary carrier to the deactivation state after a predetermined time from the transmission of the deactivation message. As the predetermined time, a predefined value may be used to prevent inconsistency of secondary-carrier state information that is managed by the base station and the terminal. If the carrier state management information is used, it is possible to prevent inconsistency of secondary-carrier states that are managed by the base station and the terminal and solve problems due to the inconsistency.
