Abstract  Abstract

An apparatus includes a User Equipment (UE) having a receiver and a decoder. The receiver is configured to receive from an eNodeB (eNB) a signal indicating a configuration of a period to receive one or more Physical Downlink Control CHannels (PDCCHs) in respective one or more Transmission Time Intervals (TTIs). Each of the one or more PDCCHs conveys a same Downlink Control Information (DCI) format. The DCI format includes at least one field indicating a first Time Division Duplexing (TDD) UpLink-DownLink (UL-DL) configuration in a first cell for DL data receptions or UL data transmissions. A TDD UL-DL configuration includes ten TTIs each having a respective serial index from 0 to 9. The receiver is also configured to receive from the eNB at least one PDCCH of the one or more PDCCHs. The decoder is configured to decode the DCI format conveyed by the at least one PDCCH in a second cell. The period is a multiple of ten TTIs and the one or more TTIs are in a last ten TTIs of the period.
