Signaling to indicate locations of dedicated random access channel region in time domain

A wireless communication node, comprising:

• a processor configured to generate a signal indicating a location of a contention free random access channel (CFRA) resource within a time region and indicating a number of actually transmitted synchronization signal block (SSB) signals, wherein:
• the CFRA resource is based at least in part on the actually transmitted SSB signals and is partially overlapping and not fully overlapping in time with respect to a contention based random access (CBRA) resource,
• the signal indicates a timing pattern for the CFRA resource via a symbol index within a radio frame and a system frame n umber configuration index,
• the timing pattern associated with a pattern of subsequent instances of the time region in which the CFRA resource is repeated, and
• the signal indicates a physical random access channel (PRACH) configuration index to provide at least one of the location of the CFRA resource, or the indication of the timing pattern for the CFRA resource, or a combination thereof, and
• the processor is further configured to determine the timing pattern based at least in part on the symbol index and the system frame number configuration index;
• and
• a transmitter configured to transmit, for one or more user equipments (UEs), the signal to indicate the location, the timing pattern, and the time region;
• and
• a receiver configured to receive, during at least one instance of the CFRA resource within the time region, a random access channel (RACH) transmission using the CFRA resource.
