In an eNB (100), which is operative to perform a semi-persistent scheduling for a UE, a scheduler (102) performs, in accordance with the service type of a service to be used by the UE, a scheduling of upstream data to be transmitted by the UE, and a radio processing unit (103) transmits, to the UE, scheduling information indicating a result of the scheduling performed by the scheduler (102). Here, when the UE is to use a service corresponding to a semi-persistent scheduling, the scheduler (102) is triggered, by the establishment of a radio bearer of the service corresponding to the semi-persistent scheduling between the eNB (100) and the UE, to perform the semi-persistent scheduling.Type: ApplicationFiled: February 18, 2011Publication date: February 14, 2013Applicant: PANASONIC CORPORATIONInventor: Takenobu Arima
