Abstract
A method and apparatus are disclosed. In an example, a first user equipment (UE) may be configured with a first number of carriers corresponding to a maximum number of carriers that the first UE is able to use concurrently and/or transmit on concurrently. The first UE may receive a plurality of sidelink transmissions on a plurality of carriers. The first UE may derive a plurality of slots for transmitting Physical Sidelink Feedback Channels (PSFCHs) based upon resources associated with the plurality of sidelink transmissions. Responsive to determining that a number of carriers of a second plurality of carriers associated with derived transmissions of the PSFCHs exceeds the first number of carriers, the first UE may prioritize one or more PSFCHs of the PSFCHs based upon a rule. The plurality of slots for transmitting the PSFCHs may be at least partially overlapped in the time domain.
