Mobile communication system, base station apparatus, mobile station apparatus, and mobile communication method

摘要

Provided is a mobile communication system in which a base station apparatus and a mobile station apparatus communicate with each other using a plurality of component carriers, wherein the base station apparatus persistently allocates a first physical uplink control channel to the mobile station apparatus, dynamically allocates a second physical uplink control channel to the mobile station apparatus, and allocates a physical uplink shared channel to the mobile station apparatus, and the mobile station apparatus performs simultaneous transmission on the physical uplink shared channel and the second physical uplink control channel when transmission on the first physical uplink control channel, transmission on the second physical uplink control channel, and transmission on the physical uplink shared channel occur in the same sub-frame.

主权项

1. A base station apparatus which receives uplink control information from a mobile station apparatus, the base station apparatus comprising:
in a case that the mobile station apparatus is enabled to perform a simultaneous transmission on a physical uplink shared channel and a physical uplink control channel in a sub-frame:
a receiver configured to receive in a sub-frame, from the mobile station apparatus, channel state information on the physical uplink control channel if the uplink control information consists only of the channel state information;the receiver configured to receive in a sub-frame, from the mobile station apparatus, hybrid automatic repeat request (HARQ) control information on the physical uplink control channel if the uplink control information consists only of the HARQ control information; andthe receiver configured to receive in a sub-frame, from the mobile station apparatus, the channel state information on the physical uplink shared channel and the HARQ control information on the physical uplink control channel if the uplink control information consists of the channel state information and the HARQ control information and if a transmission on the physical uplink shared channel is being performed.
