Abstract: A user equipment that has performed a random access procedure with respect to a base station may determine a DCI size to be monitored based on DCI size alignment and the base station may determine a DCI size to be used based on the DCI size alignment. The DCI size alignment may include aligning the size of a legacy UL DCI format and the size of a legacy DL DCI format after aligning the size of a new UL DCI format and the size of a new DL UCI format. Each of the new UL DCI format and the legacy UL DCI format is a DCI format used to schedule a physical uplink shared channel (PUSCH), and each of the new DL DCI format and the legacy DL DCI format is a DCI format used to schedule a physical downlink shared channel (PDSCH).

Abstract: A method of transmitting a physical uplink control channel (PUCCH) in a wireless communication system and a device therefor are disclosed. Specifically, the method performed by a user equipment (UE) includes receiving, from a base station (BS), configuration information for performing transmission and reception on a per subslot basis, receiving, from the BS, multiple physical downlink shared channels (PDSCHs) based on the configuration information, and transmitting, to the BS, the PUCCH including hybrid automatic repeat request (HARQ)-acknowledgement (ACK) information for the multiple PDSCHs in a specific slot. The PUCCH includes a first PUCCH transmitted in a first subslot of the specific slot and a second PUCCH transmitted in a second subslot of the specific slot. The first PUCCH and the second PUCCH each are transmitted based on a separately constructed HARQ-ACK codebook.

Abstract: Systems and techniques for transmitting a physical uplink control channel (PUCCH) carrying a scheduling request (SR) in a wireless communication system. In some implementations, a method performed by a terminal includes the steps of: receiving, from a base station, a first message related to configuration of an uplink (UL) resource; receiving, from the base station, a second message related to resource configuration of a PUCCH carrying the SR; determining a resource for transmission of the PUCCH carrying the SR; and transmitting, to the base station, the PUCCH carrying the SR on the determined resource.
