Patent ID: 11063706

Abstract:
Embodiments of an Evolved Node-B (eNB), User Equipment (UE) and methods for communication are generally described herein. The eNB may receive, from a UE, uplink control information (UCI) that indicates a hybrid automatic repeat request identifier (HARQ ID) for a grant-less uplink (GUL) transmission by the UE during a first sub-frame. The eNB may select, from candidate HARQ IDs, a HARQ ID for a scheduled uplink (SUL) transmission by another UE in a second sub-frame after the first sub-frame. The eNB may, if the GUL transmission is successfully decoded, include the HARQ ID for the GUL transmission in the candidate HARQ IDs for the GUL transmission. The eNB may, if the GUL transmission is not successfully decoded, exclude the HARQ ID for the GUL transmission from the candidate HARQ IDs for the GUL transmission.
