A method of transmitting and receiving a signal by a user equipment, UE, in a wireless communication system, the method comprising: monitoring a physical downlink control channel, PDCCH, during an on-duration based on a configured discontinuous reception, DRX, operation; starting an inactivity timer and staying awake based on successful reception of the PDCCH during the on-duration; detecting downlink control information, DCI, scheduling a single physical uplink shared channel, PUSCH, or multiple PUSCHs to be transmitted on a serving cell while staying awake; and transmitting the single PUSCH or the multiple PUSCHs on the serving cell based on the DCI, wherein the DCI is DCI format 0_1, wherein a payload size of the DCI is 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, wherein the DCI includes a codeblock group transmission information, CBGTI, field based on the scheduling of the single PUSCH, and wherein the DCI includes no CBGTI field based on the scheduling of the multiple PUSCHs, wherein the DCI includes a two-bit redundancy version, RV, field and an one-bit new data indicator, NDI, field based on the scheduling of the single PUSCH, wherein the DCI includes an N-bit RV field and an N-bit NDI field based on the scheduling of the multiple PUSCHs, and the N bits are based on a maximum number of PUSCHs schedulable by the DCI, and wherein the number of information bits for scheduling the single PUSCH is based on the CBGTI field and two-bit the RV field and the one-bit NDI field, and the number of information bits for scheduling the multiple PUSCHs is based on no CBGTI field and the N-bit RV field and the N-bit NDI field. monitoring a physical downlink control channel, PDCCH, during an on-duration based on a configured discontinuous reception, DRX, operation; starting an inactivity timer and staying awake based on successful reception of the PDCCH during the on-duration; detecting downlink control information, DCI, scheduling a single physical uplink shared channel, PUSCH, or multiple PUSCHs to be transmitted on a serving cell while staying awake; and transmitting the single PUSCH or the multiple PUSCHs on the serving cell based on the DCI, wherein the DCI is DCI format 0_1, wherein a payload size of the DCI is 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, wherein the DCI includes a codeblock group transmission information, CBGTI, field based on the scheduling of the single PUSCH, and wherein the DCI includes no CBGTI field based on the scheduling of the multiple PUSCHs, wherein the DCI includes a two-bit redundancy version, RV, field and an one-bit new data indicator, NDI, field based on the scheduling of the single PUSCH, wherein the DCI includes an N-bit RV field and an N-bit NDI field based on the scheduling of the multiple PUSCHs, and the N bits are based on a maximum number of PUSCHs schedulable by the DCI, and wherein the number of information bits for scheduling the single PUSCH is based on the CBGTI field and two-bit the RV field and the one-bit NDI field, and the number of information bits for scheduling the multiple PUSCHs is based on no CBGTI field and the N-bit RV field and the N-bit NDI field.
