摘要
A method, system and apparatus for semi-persistent channel state information (CSI) reporting procedures with uplink (UL) clear channel assessment (CCA) are disclosed. According to one aspect, a method includes receiving a signal indicating activation or deactivation of semi-persistent channel state information (CSI) reporting and responsive to receiving the signal, attempt to transmit a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK), the attempt being subject to success or failure of a clear channel assessment (CCA). When the CCA fails and when the signal indicates activation, the method includes refraining from CSI measurement and reporting unless CCA subsequently succeeds before expiry of a time interval. When the CCA fails and when the signal indicates deactivation, the method includes continuing CSI measurement but refraining from CSI reporting unless CCA subsequently succeeds before expiry of a time interval.
