Efficient and robust verification response procedures for new wireless operations in unlicensed bands

摘要

A system, method and apparatus for efficiently and robust processing of confirmation responses in a new unlicensed wireless bandwidth (nr-u) environment.A wireless transmit receive unit (WTRU) can receive control information and data transmission from the GNB at a first interval (i.e., transport block or channel occupancy time) and control information is An uplink resource may be included.Data transmission may require some kind of confirmation response (i.e. HARQ feedback).While the WTRU may try to send a confirmation response in the indicated uplink resource, the GNB may not receive the acknowledgment response.The WTRU may receive control information and data transmission from the GNB at the second interval, including an indication for aggregation of previously failed acknowledgement response transmission.The WTRU may send an integrated acknowledgement response including an earlier failed confirmation response and any additional confirmation response from the current interval.In some cases, the view before talk procedure may be used.Diagram
