Title:
WIRELESS COMMUNICATION TERMINAL, BASE STATION DEVICE, RESOURCE ALLOCATION METHOD
Document Type and Number:
WIPO Patent Application WO/2014/020819
Kind Code:
A1
Abstract:
A wireless communication terminal with which, in a system by which Enhanced Physical Downlink Control Channel (E-PDCCH) control information is transmitted, ACK/NACK resource usage efficiency can be increased, and a wasteful decrease in the bandwidth of a PUSCH can be suppressed, while avoiding an ACK/NACK conflict. The wireless communication terminal is provided with: a reception unit which receives a control signal including an ACK/NACK indicator via an E-PDCCH transmitted using any one configuration from one or a plurality of configuration candidates; a control unit which selects, on the basis of the ACK/NACK indicator and the E-PDCCH configuration information used for the E-PDCCH transmission/reception, resources used for a downlink data ACK/NACK signal from among designated resources that are designated in advance; and a transmission unit which transmits the ACK/NACK signal using the selected designated resources.
