Abstract
Techniques for determining a random access channel (RACH) procedure to use to establish an uplink connection between a user equipment (UE) and a base station are discussed herein. In some cases, when a UE is in an idle state, the UE may determine a network condition, a UE condition, or other conditions. Based on the determined conditions, the UE may select or otherwise determine to use a two-step RACH procedure or a four-step RACH procedure. In some cases, the determination of which RACH procedure to use can be based on a machine learned model, heuristic(s), rule(s), threshold(s), and the like. Based on the selection, the UE may initiate a communication with the base station using the particular RACH procedure.
