Abstract: A method and a device for allowing a terminal to transmit a signal in a wireless communication system, according to one embodiment of the present invention, map first uplink control information (UCI) and second UCI to one specific uplink channel if a resource region for transmitting the first UCI and a resource region for transmitting the second UCI are overlapped in a time domain, and transmit the specific uplink channel. Particularly, the specific uplink channel comprises a first bit payload for the first UCI and a second bit payload for the second UCI, wherein the number of bits of the first bit payload and the number of bits of the second bit payload are determined on the basis of preset ratio information.

Abstract: A method for performing wireless communication by a first device and a device for supporting same are provided. The method may comprise the steps of: receiving a physical sidelink shared channel (PSSCH) from a second device; determining a physical sidelink feedback channel (PSFCH) resource associated with the PSSCH; and transmitting hybrid automatic repeat request (HARQ) feedback to the second device on the PSFCH resource. Here, the PSFCH resource can be determined on the basis of a sub channel associated with the PSSCH, a slot associated with the PSSCH, a cast type of communication between the first device and the second device, an ID of the first device, and a source ID of the second device.

Abstract: A method of performing an operation for a first user equipment (UE) in a wireless communication system includes determining a slot for transmitting a physical uplink control channel (PUCCH) based on a value related to the number of slots from a physical sidelink feedback channel (PSFCH) to the PUCCH by the first UE, and transmitting, to a base station (BS), feedback information based on the PSFCH through the PUCCH in the slot by the first UE. The value related to the number of slots is applied based on a last of slots for the PUCCH, overlapped with a slot for the PSFCH on a time axis.

Abstract: According to one embodiment of the present disclosure, a method by which a first device performs sidelink communication is provided. The method comprises the steps of: receiving, from a base station, a sidelink grant associated with a first retransmission resource and an initial transmission resource of a transport block; transmitting, to a second device, a PSCCH and a PSSCH associated with the PSCCH, on the basis of the initial transmission resource; determining a PSFCH resource for receiving a PSFCH from the second device, on the basis of the index of a slot and the index of a subchannel associated with the PSSCH; receiving, from the second device, the PSFCH on a first PSSCH, on the basis of the PSFCH resource; comparing a time interval between the PSFCH resource and the first retransmission resource with a minimum processing time required between the reception of the PSFCH and retransmission of the transport block; and performing sidelink communication with the second device, on the basis of the comparison of the time interval and the minimum processing time, wherein retransmission for the transport block may be dropped over the first retransmission resource by the first device, on the basis of the fact that the transport block is a transport block for which sidelink HARQ feedback is activated and the time interval is less than the minimum processing time.

Abstract: A method of receiving a physical downlink shared channel (PDSCH) by a user equipment (UE) in a wireless communication system includes receiving first information about a PDSCH time-domain resource assignment table including a plurality of candidate PDSCH time-domain resource assignment information, receiving second information about a minimum offset value for an interval between a slot in which a physical downlink control channel (PDCCH) is received and a slot to which a PDSCH is allocated, and receiving the PDSCH based on candidate PDSCH time-domain resource assignment information including an offset value equal to or larger than the minimum offset value among the candidate PDSCH time-domain resource assignment information. The PDSCH is received based on one of the candidate PDSCH time-domain resource assignment information irrespective of the minimum offset value, based on a PDCCH for scheduling the PDSCH, being related to system information (SI), a random access response (RAR), or paging.
