Abstract

A method includes receiving a first scheduling information in a first slot, the first scheduling information including a first assignment for a reception of a first transport block (TB), and a first communication priority for a transmission of a first HARQ feedback message associated with the reception of the first TB and being scheduled for transmission in a first resource of a feedback slot; transmitting a second scheduling information in a second slot, the second scheduling information comprising a second assignment for a transmission of a second TB, and a second communication priority for a transmission of a second HARQ feedback message associated with the transmission of the second TB and being scheduled for transmission in a second resource of the feedback slot; and communicating the first HARQ feedback message and the second HARQ feedback message in accordance with comparison of the first communication priority with the second communication priority.
