A method for transmitting uplink control information in a mobile station of a wireless communication system includes performing reverse repetition coding with respect to first uplink control information, and performing joint coding with respect to the reverse repetition coded first uplink control information and second uplink control information. The first uplink control information has higher priority than the second uplink control information. | 2012-11-22 |
20120294269 | PROCESSING METHOD AND MOBILE STATION DEVICE - A communication system, a mobile station device, a base station device, and a processing method for carrying out processing involved in introducing a contention based uplink efficiently, and carrying out communication promptly, are provided. A mobile station device communicating with a base station device in a mobile communication system includes a buffer for a contention based uplink and a buffer for a regular uplink HARQ, as a buffer for a HARQ. | 2012-11-22 |
20120294270 | PROCESSING METHOD AND MOBILE STATION DEVICE - A communication system, a mobile station device, a base station device, and a processing method for carrying out processing involved in introducing a contention based uplink efficiently, and carrying out communication promptly are provided. A mobile station device communicating with a base station device in a mobile communication system obtains an uplink grant from the base station device, and when a timer for prohibiting transmission of a scheduling request is not running, uses a contention based uplink when the uplink grant is a grant for a contention based uplink, and when the timer for prohibiting transmission of a scheduling request is running, does not use the contention based uplink when the uplink grant is a grant for a contention based uplink. | 2012-11-22 |
20120294271 | MOBILE STATION AND CONTROL INFORMATION DECODING METHOD - A mobile station capable of efficiently detecting control information addressed thereto, by prioritizing CRC decoding to control channel element at a candidate position, is disclosed. | 2012-11-22 |
20120294272 | METHOD AND APPARATUS FOR TRANSMITTING CONTROL INFORMATION IN A WIRELESS COMMUNICATION SYSTEM - The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting acknowledgement/negative ACK (ACK/NACK) in a wireless communication system which supports carrier aggregation, and to an apparatus for the method. A method in which a terminal transmits ACK/NACK in a wireless communication system that supports carrier aggregation comprises the following steps: receiving one or more physical downlink shared channels (PDSCHs); and transmitting ACK/NACK for said one or more PDSCHs via a physical uplink control channel (PUCCH). A PUCCH format for transmitting ACK/NACK is selected by taking the type of the carrier in which said one or more PDSCHs are received into account. | 2012-11-22 |
