BASE STATION DEVICE, TERMINAL DEVICE, AND TRANSMISSION METHOD

Title:

BASE STATION DEVICE, TERMINAL DEVICE, AND TRANSMISSION METHOD

Document Type and Number:

WIPO Patent Application WO/2015/012119

Kind Code:

A1

Abstract:

Provided are a base station device, a terminal device, and a transmission method, with which it is possible to detect a desired signal at high accuracy, irrespective of whether an interference signal is an initial transmission signal or a retransmission signal. The base station device notifies terminal devices of terminal information representing information about other terminal devices that may be causing interference, and is provided with a terminal information generation unit for generating the terminal information. The terminal information generation unit generates terminal information composed of different information, depending on the redundancy version of the interference signal. Even in instances in which the interference signal has been transmitted using a redundancy version of numerous parity bits, a terminal device can perform appropriate interference suppression and elimination, thereby improving throughput.
