1. A method comprising:
receiving, by a User Equipment (UE) from another UE, a data through a physical sidelink shared channel (PSSCH); and
transmitting, by the UE to the another UE, a Hybrid Automatic Repeat and request (HARQ)-ACK information through a Physical Sidelink Feedback Channel (PSFCH) in response to receiving the data through the PSSCH,
wherein a first resource pool related to the PSSCH includes PSSCH slot-subchannel based units, and a second resource pool related to the PSFCH includes PSFCH slot-PRB based units,
wherein the PSSCH slot-subchannel based units are associated with the PSFCH slot-PRB based units,
wherein the PSFCH slot-PRB based units are sequentially mapped to the PSSCH slot-subchannel based units from smallest index of the PSFCH slot-PRB based units in frequency domain, and
wherein the PSFCH slot-PRB based units are mapped to the PSSCH slot-subchannel based units, the mapping starts in ascending order of a smallest slot index of the PSSCH slot-subchannel based units and continues in ascending order of smallest subchannel index of the PSSCH slot-subchannel based units.
