Power ramping for random access channel (RACH) preamble transmissions with beam switching

Abstract:

Certain aspects of the present disclosure provide techniques for transmitting a random access channel (RACH) preamble. For example, certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes generating a message comprising a random access channel (RACH) preamble, determining an order of a plurality of beams for transmitting the message based on an indication of the order, and transmitting the message, to a network node, via the plurality of beams in accordance with the determined order of the beams.
