1. A method of wireless communication performed by a user equipment (UE), comprising:
receiving, during a first state, a configuration of a sounding reference signal (SRS) resource or SRS resource set;
obtaining an association between the SRS resource or SRS resource set and a group of random access channel (RACH) resources; and
transmitting, while outside the first state, a group of RACH signals using transmission properties based on the association between the SRS resource or SRS resource set and the group of RACH resources, wherein the group of RACH resources spans a plurality of adjacent frequency resources over a single time resource, or the group or RACH resources spans the plurality of adjacent frequency resources over a plurality of time resources.
