摘要

The method and device for transmitting and receiving signals in a wireless communication system, according to one embodiment of the present invention, comprise: receiving downlink control information (DCI) for scheduling a single physical uplink shared channel (PUSCH) or a plurality of PUSCHs to be transmitted on a serving cell; and transmitting the single PUSCH or the plurality of PUSCHs on the serving cell on the basis of the DCI, wherein the payload size of the DCI may be determined on the basis of the larger one of the number of bits of the pieces of information for scheduling the single PUSCH and the number of bits of the pieces of information for scheduling the plurality of PUSCHs.

說(shuō)明書

The PDCCH may be transmitted in the DL control region, and the PDSCH may be transmitted in the DL data region. The PUCCH may be transmitted in the UL control region, and the PUSCH may be transmitted in the UL data region. The GP provides a time gap in the process of the UE switching from the transmission mode to the reception mode or from the reception mode to the transmission mode. Some symbols at the time of switching from DL to UL within a subframe may be configured as the GP.

In the present disclosure, a base station (BS) may be, for example, a gNode B (gNB).

FIG. 4 illustrates an ACK/NACK transmission process. Referring to FIG. 4, the UE may detect a PDCCH in slot #n. The PDCCH includes DL scheduling information (e.g., DCI format 1_0 or DCI format 1_1). The PDCCH indicates a DL assignment-to-PDSCH offset, K0 and a PDSCH-to-HARQ-ACK reporting offset, K1. For example, DCI format 1_0 or DCI format 1_1 may include the following information.

    • Frequency domain resource assignment: Indicates an RB set assigned to a PDSCH.
    • Time domain resource assignment: Indicates K0 and the starting position (e.g., OFDM symbol index) and length (e.g., the number of OFDM symbols) of the PDSCH in a slot.
    • PDSCH-to-HARQ feedback timing indicator: Indicates K1.
