Title:
TERMINAL DEVICE, BASE STATION DEVICE, COMMUNICATION METHOD AND INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2018/061501
Kind Code:
A1
Abstract:
Provided is a terminal device that: transmits one random access preamble using a plurality of time intervals; changes, for each of one or more time intervals of the plurality of time intervals, a transmission beam used to transmit the one random access preamble; and monitors a random access response to the one random access preamble. The random access response includes first information for identifying any one of the plurality of time intervals.
