Title:
TERMINAL DEVICE, BASE STATION DEVICE, COMMUNICATION METHOD, AND INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2018/230726
Kind Code:
A1
Abstract:
This terminal device receives, from a base station device, a signal that includes directive information directing the commencement of a random access procedure. The terminal device transmits one or a plurality of random access preambles on the basis of the directive information, and determines, on the basis of information that relates to SRS resources and is included in the directive information, an antenna port to use for the transmission of the random access preamble(s).
