Title:
TERMINAL DEVICE, BASE STATION DEVICE, AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/074071
Kind Code:
A1
Abstract:
A communication method to be used by a terminal device, the method being provided with a step for separately creating a first encoded bit fk of a transport block, a second encoded bit q0 of control information, and a third encoded bit q1 of a rank indicator, and creating a multiplexed bit gk by multiplexing the first encoded bit fk
and the second encoded bit q0, and a step for creating a first sequence hk by multiplexing the multiplexed bit gk and the third encoded bit q1, wherein the location where the third encoded bit q1 is mapped is assigned on the basis of at least one condition among a first condition, a second condition, and a third condition. The first condition is whether the search space where the PDCCH is detected is CSS or USS, the second condition is whether the CRC parity bit added to the DCI format is an RNTI and is scrambled, and the third condition is whether a first method or a second method is used for the first encoded bit.
