9, system according to claim 8 is characterized in that, during at least two of the Metric of maximum occurrences, described base station is further used for sending signaling to UE; UE is further used for selecting corresponding PUCCH resource according to the described signaling of receiving; Perhaps, in the Metric of identical maximum occurrences, select corresponding PUCCH resource according to setting rule.

10, system according to claim 8, it is characterized in that, described base station is further used for the implicit mapping according to the PUCCH resource index of the PUCCH resource of the CCE index of first CCE of PDCCH and UE transmission HARQ-ACK package informatin, avoids the Metric of identical maximum occurrences to occur by scheduling.
