Abstract: A method for receiving a PDCCH by a terminal in a mobile communication system may comprise the steps of: receiving a first PDCCH including first DCI from a base station through a first PDCCH search space; and receiving a second PDCCH including second DCI from the base station through a second PDCCH search space, wherein the first DCI and second DCI are for scheduling the same PDSCH for the same TB or TBs associated with the same HARQ process, are for scheduling different PDSCHs for the same TB or TBs associated with the same HARQ process, or are for scheduling different PDSCHs for different TBs or TBs associated with different HARQ processes. In addition, the first DCI and second DCI may be received from the base station within a time window.

Abstract: A sidelink communication method performed by a UE in a communication system may comprise receiving, from a base station, a message including configuration information of a subchannel which is a sensing unit of a resource pool; determining a size of the subchannel based on the configuration information; and performing a sensing operation in units of the subchannel in the resource pool. Therefore, the sidelink communication can be efficiently performed, and the performance of the communication system can be improved.

Abstract: An operation method for a communication node transmitting system information in a communication network is an operation method for a base station which transmits system information in a communication network, and includes: configuring information on a request time when system information is requested and a transmission time when the system information is transmitted in a communication network; transmitting a message including the configured information on the request time and the transmission time by using a broadcast-based method; receiving, from at least one user equipment included in the communication network, a message requesting the system information on the basis of the request time; and transmitting a message including the system information to the at least one user equipment on the basis of the transmission time.

Abstract: A method and an apparatus for communications using synchronization signal blocks. An operation method of a base station in a mobile communication system includes generating a first synchronization signal/physical broadcast channel (SS/PBCH) block including information indicating whether the first SS/PBCH block is used for initial access of the terminal; and transmitting the generated SS/PBCH block in a first bandwidth part (BP).
