BASE STATION APPARATUS, MOBILE STATION APPARATUS, AND TRANSMISSION METHOD |
摘要 |
A base station able to maintain backward compatibility with an LTE mobile station while minimizing the amount of increase in uplink scheduling information reception and demodulation/decoding processing in independent uplink/downlink cell data transmission. A wireless communication system includes a cell #1, a cell #2, and an LTE-A mobile station, and supports independent uplink/downlink cell data transmission. The base station of the cell #2 arranges a PDCCH+, which includes uplink scheduling information from the LTE-A mobile station to the base station of the cell #2, in a downlink data region in the downlink connection of the base station of the cell #1. |

1. An integrated circuit to control a process performed by mobile station apparatus receiving downlink data that is transmitted from a first cell and transmitting uplink data to a second cell on a physical uplink shared channel (PUSCH), the process comprising:
receiving first control information including scheduling information of the PUSCH, the first control information being mapped in in a part of a data channel region, the data channel region being different from a control channel region, in which second control information including scheduling information of the downlink data is mapped; mapping the uplink data in a resource indicated by the scheduling information of the uplink data; and transmitting the mapped uplink data. |
