Title:
TERMINAL, WIRELESS COMMUNICATION METHOD, AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2023/170905
Kind Code:
A1
Abstract:
Provided is a terminal according to one embodiment of the present disclosure characterized to have: a receiving unit that receives an antenna port instruction in a case where a set demodulation reference signal (DMRS) type and/or the maximum length of the DMRS is not 1; and a control unit that, on the basis of the antenna port instruction, controls uplink (UL) transmissions which correspond to two codewords and use the number of layers greater than four. Said one embodiment makes it possible to suitably control UL transmission with the number of layers greater than four.
