1. A method for transmitting and receiving data by a first user equipment (UE) in a communication system, the method comprising:
receiving sidelink repetitive transmission information from a base station;
performing physical sidelink shared channel (PSSCH) repetitive transmissions including sidelink data for a second UE based on the sidelink repetitive transmission information, the sidelink repetitive transmission information including at least one of a first number of repetitive transmissions for the PSSCH, and time/frequency resource information used for repetitive transmissions of the PSSCH; and
determining a second number of repetitive transmissions for the PSSCH based on response information received by the first UE from the second UE in response to the PSSCH repetitive transmissions,
wherein the second number of repetitive transmissions is equal to, greater than, or less than the first number of repetitive transmissions.
