    摘要: Disclosed is a resource allocation method in sidelink communication. An operation method of a terminal includes the steps of: receiving a first message, including mobility conditions to be used for selecting a resource allocation mode for sidelink communication, from a base station; selecting the resource allocation mode to be applied to the terminal, the selection being made on the basis of the results of a comparison between the mobility of the terminal and the mobility conditions; determining a resource pool on the basis of the selected resource allocation mode; and performing the sidelink communication by using the determined resource pool. Accordingly, the performance of a communication system can be enhanced.

    摘要: Disclosed are a method and apparatus for transmitting and receiving an HARQ response in a communication system. An operation method of a first terminal comprises the steps of: configuring a first HARQ identifier mapped to a first HARQ feedback resource; transmitting, to a second terminal, a message including the first HARQ identifier; transmitting sidelink data to a plurality of terminals belonging to a groupcast group in a groupcast method; and receiving, from the second terminal, an HARQ response to the sidelink data in the first HARQ feedback resource mapped to the first HARQ identifier.
