Re-synchronization management for wireless communications in unlicensed spectrum

An apparatus configured for wireless communication, the apparatus comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor, wherein the at least one processor is configured to:
• receive, at a user equipment (UE), an indication identifying an uplink re-synchronization procedure for use in an unlicensed spectrum;
• perform an extended clear channel assessment (ECCA) check prior to a re-synchronization boundary associated with the uplink re-synchronization procedure;
• perform, based on success of the ECCA check, a clear channel assessment (CCA) check in a subframe preceding the re-synchronization boundary;
• and
• transmit data beginning at the re-synchronization boundary in response to successfully completing both the CCA check and the ECCA check.
