Claim of US Patent No. 10,973,015

1. A method of performing, by a user equipment (UE), uplink transmission in a wireless communication system, the method comprising:receiving, from a base station (BS), first radio resource control (RRC) configuration information for a configured grant-based physical uplink shared channel (PUSCH);
receiving, from the BS, second RRC configuration information for a dynamic grant-based PUSCH;
receiving, from the BS, a first downlink control information (DCI) that is scrambled by a configured scheduling (CS)-radio network temporary identifier (RNTI);
validating the first DCI as a valid activation or a valid release of the configured grant-based PUSCH;
applying parameters of the first RRC configuration information to the first DCI, according to a DCI format of the first DCI, for a configured grant-based PUSCH transmission;
performing the configured grant-based PUSCH transmission to the BS;
receiving, from the BS, a second DCI that is scrambled by the CS-RNTI; and
based on a new data indicator (NDI) field of the second DCI indicating a PUSCH re-transmission: (i) applying parameters of the second RRC configuration information to the second DCI, according to the same DCI format as the first DCI, for the PUSCH re-transmission, and (ii) performing the PUSCH re-transmission to the BS,
wherein at least one field of the first DCI that is scrambled by the CS-RNTI comprises zero-padding to have a same size as each corresponding at least one field of a third DCI that is scrambled by a cell-RNTI (C-RNTI), wherein the third DCI has the same DCI format as the first DCI.
