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 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: Provided is a method for transmitting paging information in a cellular system. An object of the method is transmitting paging information which can improve applicability of a limited radio resource by variably and flexibly setting up and mapping a transport channel and a physical channel in order to transmit information notifying start of downlink information from a base station to a terminal in a cellular system for packet transmission. The method includes the steps of: forming a paging channel (PCH) in a transport channel corresponding to generation of paging information; setting a paging indication channel (PICH) based on the paging information and forming the paging indication channel in a radio resource of a physical layer; and allocating the paging channel to the radio resource of the physical layer.

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 are a method and an apparatus for transmitting or receiving uplink feedback information in a communication system. An operation method of a terminal may comprise receiving downlink control information (DCI) from a base station, the DCI including resource allocation information of a physical downlink shared channel (PDSCH); receiving data #n from the base station through the PDSCH indicated by the DCI; generating a hybrid automatic repeat request (HARQ) codebook including an HARQ response bit #n for the data #n and an HARQ response bit #n−1 for data #n−1 received from the base station before the data #n; and transmitting the HARQ codebook to the base station. Therefore, the performance of the communication system can be improved.
