Hybrid Automatic Repeat Request Acknowledgment Feedback Using Periodic and Aperiodic Physical Uplink Control Channel Resources

摘要

Various communication systems may benefit from an appropriate usage of resources. For example, certain wireless communication systems may benefit from appropriate usage of periodic and aperiodic physical uplink control channel resources for hybrid automatic repeat request acknowledgment feedback. A method can include receiving, from an access node, an acknowledgment/negative acknowledgement resource indicator in a downlink assignment. The indicator can correspond to two or three resource sets. The method can also include determining, by a user equipment, a resource for hybrid automatic repeat request acknowledgment transmission based on the acknowledgment/negative acknowledgement resource indicator and based on an outcome of a listen before talk procedure.
