TERMINAL, BASE STATION, COMMUNICATION SYSTEM, AND COMMUNICATION METHOD
First Claim
1. A terminal communicating with a base station in a cell, the terminal comprising:
- a downlink control channel detection module that monitors an physical downlink control channel in a first physical downlink control channel-physical resource block set and a second physical downlink control channel-physical resource block set;
a data extraction module that extracts transmission data in a physical downlink shared channel associated with a detected physical downlink control channel, in a case where the downlink control channel detection module detects the physical downlink control channel;
a response information generation module that generates response information responding to the extracted transmission data;
an uplink control channel generation module that generates a physical uplink control channel by mapping the response information to a physical uplink control channel resource that is determined in accordance at least with an index of an element that constructs a physical downlink control channel resource in which the physical downlink control channel is detected and with a prescribed offset, in a case where the downlink control channel detection module detects the physical downlink control channel in the first physical downlink control channel-physical resource block set, and that generates the physical uplink control channel by mapping the response information to a physical uplink control channel resource that is determined in accordance at least with the index of the element that constructs the physical downlink control channel resource in which the physical downlink control channel is detected and with an offset which is configured by dedicated RRC signaling, in a case where the downlink control channel detection module detects the physical downlink control channel in the second physical downlink control channel-physical resource block set; and
a response transmission module that transmits a signal that includes the physical uplink control channel.

Abstract
Provided is a terminal that performs communication with a base station, in which a Physical Uplink Control Channel is generated by mapping response information to a Physical Uplink Control Channel resource that is determined in accordance with at least a prescribed offset and generates a Physical Uplink Control Channel, in a case where a Physical Downlink Control Channel is detected in a first Enhanced Physical Downlink Control Channel-Physical Resource Block set, and in which a Physical Uplink Control Channel is generated by mapping the response information to a Physical Uplink Control Channel resource that is determined in accordance with at least an offset which is configured individually for every terminal and generates the Physical Uplink Control Channel, in a case where the Physical Downlink Control Channel is detected in a second Enhanced Physical Downlink Control Channel-Physical Resource Block set.
