Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present invention provides a method of a base station for supporting an inter-system handover from an evolved packet system (EPS) system to a 5th generation (5G) system. The present application provides a method for transmitting HARQ-ACK information, including steps of: detecting, by a UE, a PDCCH and receiving a PDSCH scheduled by the PDCCH; for one slot of one carrier, determining, according to a configured slot pattern and a configured PDCCH monitoring occasion, the HARQ-ACK occasion and the number of HARQ-ACK bits occupied by the one slot; and, generating, by the UE, an HARQ-ACK codebook according to the HARQ-ACK occasion and the number of HARQ-ACK bits occupied by the one slot, and transmitting HARQ-ACK information. By the method of the present invention, the number of HARQ-ACK bits to be fed back within each slot is reduced, and the feedback overhead is reduced; moreover, the number of bits of the generated HARQ-ACK codebook changes semi-statically, so that the confusion between a base station and a UE is avoided.

Abstract: A method and an apparatus in a wireless communication system are provided. Configuration information is received on resource pools in multiple carriers for a vehicle to everything (V2X) sidelink communication, At least one carrier is selected for transmission among the multiple carriers. An order of the at least one carrier is determined according to a decreasing order based on a highest priority of a sidelink traffic channel. A set of candidate resources associated with each of the at least one carrier is determined according to the determined order. A candidate resource is excluded from the set of candidate resources, in case that the candidate resource is not supported due to a limitation of a user equipment (UE) in supported carrier combinations.
