TECHNIQUES FOR CONFIGURING REFERENCE SIGNALS FOR RANDOM ACCESS MESSAGES IN WIRELESS COMMUNICATIONS

Abstract:

Aspects described herein relate to a user equipment (UE) determining a reference signal port of multiple configured reference signal ports to use in transmitting a reference signal for a random access message. In one aspect, a configuration indicating multiple reference signal ports to use in transmitting reference signals for a random access message can be transmitted to the UE, as well as an indication of a reference signal port of the multiple reference signal ports to be used in transmitting a reference signal for the random access message.
