Abstract
A method includes determining a first sidelink feedback resource in accordance with a first sidelink transmission received from a second user equipment (UE), the first sidelink feedback resource comprising a first frequency resource and a first time resource, the first sidelink feedback resource being associated with a first sidelink feedback message responsive to the first sidelink transmission; determining a second sidelink feedback resource in accordance with a second sidelink transmission received from a third UE, the second sidelink feedback resource comprising a second frequency resource and the first time resource, the second sidelink feedback resource being associated with a second sidelink feedback message responsive to the second sidelink transmission; multiplexing the first sidelink feedback message and the second sidelink feedback message; and transmitting the multiplexed first and second sidelink feedback messages in a third frequency resource.
