Abstract: A UE can receive a UL grant setting for set UL grants. The UE determines hybrid automatic repeat request (HARQ) process identifiers (IDs) for cycles of the set UL grants on the basis of the UL grant setting, and can perform UL channel transmission in at least one of transmission periods corresponding to the set UL grants within the cycles on the basis of the determined HARQ process IDs. Determining the HARQ process IDs for the cycles can include determining start HARQ process IDs of the HARQ process IDs on the basis of HARQ process ID intervals. The HARQ process ID intervals are the minimum differences among the start HARQ process IDs for different cycles.

Abstract: A base station and a user equipment may determine whether to determine a start symbol value representing a start symbol of a physical downlink shared channel (PDSCH) on the basis of a reference point which is different from the start of a slot allocated for the PDSCH of a cell and is based on the subcarrier spacing of the cell and the subcarrier spacing of a scheduling cell for the cell. The base station/user equipment may transmit/receive, through the scheduling cell, the DCI including symbol information on the start symbol value for the PDSCH on the basis of the determination.
