BASE STATION, RADIO COMMUNICATION TERMINAL, RADIO COMMUNICATION SYSTEM, AND RADIO COMMUNICATION METHOD

Title:

BASE STATION, RADIO COMMUNICATION TERMINAL, RADIO COMMUNICATION SYSTEM, AND RADIO COMMUNICATION METHOD

Document Type and Number:

WIPO Patent Application WO/2019/187146

Kind Code:

A1

Abstract:

The base station (100) has a PDSCH/MCS control unit (110), an ACK reception MCS-ACK index determination unit (112), and a radio reception unit (102). The PDSCH/MCS control unit (110) determines a coding and modulation scheme for a signal to be transmitted to a radio communication terminal. The ACK reception MCS-ACK index determination unit (112) determines resources to be used in the transmission of a response signal to the aforementioned signal by reference to association information associating such resources to the coding and modulation scheme applied to the aforementioned signal. The radio reception unit (102) receives the aforementioned response signal transmitted using the aforementioned resources.
