Abstract
Systems, methods, and instrumentalities are disclosed for Random Access Channel (RACH) procedures in unlicensed spectrum. A wireless transmit/receive unit (WTRU) may monitor for a random access response (RAR) or a reference signal (RS), e.g. in an RAR window. The WTRU may determine whether an RS has been received a threshold amount of times, e.g. if an RAR is not received. The WTRU may continue to monitor for an RAR or an RS, e.g. if the RS has not been received a threshold amount of times and the RAR window is not at a maximum RAR window size.
