Methods and apparatuses are described herein for reporting channel failure, and may be used, among others, for New Radio (NR) operation in unlicensed spectrum (NR-U). Upon detecting a consistent uplink (UL) listen-before-talk (LBT) failure or upon detecting a beam failure on a cell, a Scheduling Request (SR) may be triggered to have a UL resource granted for transmission of the failure to another cell, or to a subset of other cells, using, for example, a failure recovery Medium Access Control-Control Element (MAC-CE).

In some cases, a WTRU may initiate a random-access procedure for transmitting the MAC-CE, for example when resources for failure reporting are not configured.
