Abstract: A wireless transmit receive unit (WTRU) and methods are disclosed for mitigating radar interference with transmission and reception of RACH preambles. According to a first aspect, one or more first RACH preambles are transmitted based on a first RACH configuration. The WTRU may receive an RAR with an indication that the first RACH configuration is unavailable. The WTRU may then retrieve a second RACH configuration information. The WTRU may then transmit one or more second RACH preambles based on the second RACH configuration and then completes a random access procedure based on the second RACH configuration.
