Abstract
A method and apparatus are disclosed from the perspective of a first device, wherein the first device is configured with a sidelink resource pool comprising a frequency region of sidelink data transmission and multiple frequency regions of sidelink feedback transmission, wherein the multiple frequency regions of sidelink feedback transmission in one TTI (Transmission Time Interval) are separately associated with the one frequency region of sidelink data transmission in multiple TTIs, and wherein the multiple frequency regions of sidelink feedback transmission in the one TTI are non-overlapped with each other in frequency domain and fully overlapped in time domain. In one embodiment, the method includes the first device receiving a sidelink data transmission from a second device within the frequency region of sidelink data transmission in a first TTI. The method further includes the first device generating a feedback information associated with the sidelink data transmission. The method also includes the first device determining or deriving a sidelink feedback resource within one frequency region of sidelink feedback transmission among the multiple frequency regions of sidelink feed…
