Abstract: An operation method of a source terminal for sidelink communication comprises transmitting at least two transport blocks (TBs) or code block groups (CBGs) to a destination terminal, and receiving hybrid automatic repeat request-acknowledgement/negative acknowledgement (HARQ-ACK/NACK) bits for the at least two TBs or CBGs from the destination terminal. The operation method further comprises generating an HARQ codebook based on the HARQ-ACK/NACK bits, and reporting the generated HARQ codebook to a serving base station.

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: Disclosed are methods and apparatuses for transmitting and receiving signals in a communication system supporting unlicensed bands. An operation method of a terminal may comprise acquiring a time period for occupying a channel by performing a sensing operation on the channel; transmitting a first uplink signal to a base station in a first uplink period within the time period; receiving DCI from the base station in a downlink period within the time period, the DCI including an uplink grant; and transmitting a second uplink signal to the base station in a second uplink period indicated by the uplink grant within the time period. Thus, performance of the communication system can be improved.
