Techniques for selecting a random access channel occasion

A method for wireless communications at a network entity, comprising:

• determining a plurality of random access channel occasion types and a channel quality threshold for each random access channel occasion type of the plurality of random access channel occasion type, the plurality of random access channel occasion types comprising a time division multiplexing type, a frequency division multiplexing type, a spatial division multiplexing type, or a combination thereof;
• transmitting, to a user equipment (UE), control signaling identifying a configuration that indicates the plurality of random access channel occasion types and the channel quality threshold for each random access channel occasion type of the plurality of random access channel occasion types;
• and
• receiving a random access channel preamble in a random access channel occasion type based at least in part on a multiplexing scheme comprising a random access channel occasion type of the plurality of random access channel occasion types.

An apparatus for wireless communications at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a network entity, control signaling identifying a configuration that indicates a plurality of random access channel occasion types and a channel quality threshold for each random access channel occasion type of the plurality of random access channel occasion types, the plurality of random access channel occasion types comprising a time division multiplexing type, a frequency division multiplexing type, a spatial division multiplexing type, or a combination thereof;
• select, based at least in part on the configuration and a channel quality between the UE and the network entity, a random access channel occasion type of the plurality of random access channel occasion types and a random access channel occasion associated with the selected random access channel occasion type;
• and
• transmit a random access channel preamble in the selected random access channel occasion type based at least in part on a multiplexing scheme comprising the selected random access channel occasion type.
