CCE + NUMBER ALLOCATION METHOD AND BASE STATION DEVICE |
摘要 |
Disclosed is a CCE+ number allocation method which reduces the ACK/NACK (Acknowledgment/Negative Acknowledgment) collision probability in a mixed system containing an LTE (Long Term Evolution) system and an LTE+ (Long Term Evolution Advanced) system. A CCE(Control Channel Element)+ number is defined by selecting a number from CCE numbers of the CCE to contain PDCCH (Physical Downlink Control Channel) allocated in a resource element region constituting CCE+ where PDCCH + is arranged. This can prevent overlapped selection of the CCE number and the CCE + number even when the PDCCH and the PDCCH+ are simultaneously transmitted. Thus, it is possible to reduce the collision probability of ACK/NACK correlated to the CCE number and the CCE+ number. |
