In another aspect of the present disclosure, a computer readable storage medium having at least one computer program that, when executed, cause at least one processor to perform operations. The operations may include: receiving DCI scheduling a single PUSCH or multiple PUSCHs to be transmitted on a serving cell; and transmitting the single PUSCH or the multiple PUSCHs on the serving cell based on the DCI. A payload size of the DCI may be determined based on a larger of a number of information bits for scheduling the single PUSCH and a number of information bits for scheduling the multiple PUSCHs.
In another aspect of the present disclosure, a method of transmitting and receiving a signal by a base station in a wireless communication system is provided. The method may include: transmitting DCI scheduling a single PUSCH or multiple PUSCHs to be transmitted on a serving cell; and receiving the single PUSCH or the multiple PUSCHs on the serving cell based on the DCI. A payload size of the DCI may be determined based on a larger of a number of information bits for scheduling the single PUSCH and a number of information bits for scheduling the multiple PUSCHs.
