    Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing unified RACH for multiple features. For example, some aspects of this disclosure relate to a method including determining, by a user equipment (UE), a feature to be indicated at an initial access of the UE to a base station and determining whether the UE and the base station support feature specific random access (RA) procedure for the feature. The method further includes determining whether a condition for the feature is satisfied in response to determining that both the UE and the base station support the feature specific RA procedure for the feature. In response to determining that the condition is satisfied, the method includes selecting a feature specific Random Access Channel (RACH) resource and perform a 4-step RA procedure or a 2-step RA procedure based on the selected feature specific RACH resource.
