Methods and apparatus for selecting random access occasions in systems where multiple types of random access occasions are configured

A wireless transmit/receive unit (WTRU) configured with a plurality of random access occasions (ROs), wherein each of the plurality of ROs is one of a first type of RO or a second type of RO, the WTRU comprising:

• a transceiver;
• and
• a processor,
• wherein the transceiver and the processor are configured to select a synchronization signal block (SSB) from a plurality of SSBs for a random access preamble transmission, wherein each of the plurality of SSBs is mapped to a subset of the plurality of ROs,
• wherein the transceiver and the processor are further configured to identify a closest RO of the first type to a current frame,
• wherein the transceiver and the processor are further configured to identify a closest RO of the second type to the current frame,
• wherein the transceiver and the processor are further configured to select either the closest RO of the first type or the closest RO of the second type based on one or more RO selection criteria, and
• wherein the transceiver and the processor are further configured to send the random access preamble in the selected RO.
