Mobile communication system, base station device, mobile station device, communication method, and integrated circuit

摘要

A mobile communication system, a base station device, a mobile station device, a communication method, and an integrated circuit that each can efficiently transmit HARQ-ACK and/or channel state information are provided.;A mobile station device includes means for receiving a first parameter that is used for instructing whether simultaneous transmission of information relating to HARQ-ACK and channel state information is allowed or not; and means for receiving a second parameter that is used for instructing whether simultaneous transmission of the information relating to HARQ-ACK and the channel state information is allowed or not, and controls a transmission method of the information relating to HARQ-ACK and the channel state information based on the first parameter, the second parameter, and whether or not the information relating to HARQ-ACK corresponds to transmission on a single physical downlink shared channel only on a primary cell.

主权项

1. A mobile station device that communicates with a base station device by using a plurality of serving cells, wherein the plurality of serving cells includes a primary cell and at least one secondary cell, the mobile station device comprising:
a receiving circuitry configured to:
receive a first parameter that is used for indicating that simultaneous transmission of Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) and channel state information using a first physical uplink control channel format is allowed;receive a second parameter that is used for indicating that simultaneous transmission of HARQ-ACK and channel state information using a second physical uplink control channel format is allowed; and a determining circuitry configured to determine, in a case of collision between the HARQ-ACK and the channel state information in a same sub-frame with a physical uplink control channel, the same sub-frame being a subframe without a physical uplink shared channel, based on the first parameter, the second parameter and whether or not the HARQ-ACK corresponds to a single physical downlink shared channel transmission only on the primary cell, whether the channel state information multiplexed with the HARQ-ACK is transmitted using the first physical uplink control channel format, the channel state information multiplexed with the HARQ-ACK is transmitted using the second physical uplink control channel format, or the channel state information is dropped.
