1. A wireless communication node, comprising:
one or more processors configured to generate a signal indicating a contention free random access (CFRA) resource 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 comprises an indication of a timing pattern for the CFRA resource,
the timing pattern is associated with a pattern of subsequent instances of a time region in which the CFRA resource is repeated, and
the signal indicates a physical random access channel (PRACH) configuration index to provide the indication of the timing pattern for the CFRA resource;
a transmitter configured to transmit the signal to indicate the timing pattern using a first radio access technology (RAT); and
a receiver configured to receive, during at least one instance of the CFRA resource, a random access channel (RACH) transmission using a second RAT, the second RAT being different from the first RAT.
 
9. A method for wireless communication at a node, comprising:
generating a signal indicating a contention free random access (CFRA) resource 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 comprises an indication of a timing pattern for the CFRA resource, the timing pattern is associated with a pattern of subsequent instances of a time region in which the CFRA resource is repeated, and
the signal indicates a physical random access channel (PRACH) configuration index to provide the indication of the timing pattern for the CFRA resource;
transmitting the signal to indicate the timing pattern using a first radio access technology (RAT); and
receiving, during at least one instance of the CFRA resource, a random access channel (RACH) transmission using a second RAT, the second RAT being different from the first RAT.
 
17. An apparatus for wireless communication, comprising:
one or more processors;
one or more memories in electronic communication with the one or more processors; and
instructions stored in the one or more memories and operable, when executed by the one or more processors, to cause the apparatus to:
generate a signal indicating a contention free random access (CFRA) resource 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 comprises an indication of a timing pattern for the CFRA resource, the timing pattern is associated with a pattern of subsequent instances of a time region in which the CFRA resource is repeated, and
the signal indicates a physical random access channel (PRACH) configuration index to provide the indication of the timing pattern for the CFRA resource;
transmit the signal to indicate the timing pattern using a first radio access technology (RAT); and
receive, during at least one instance of the CFRA resource, a random access channel (RACH) transmission using a second RAT, the second RAT being different from the first RAT.
