Patent ID: 10237863

Abstract:
A communication device for handling a HARQ process in a LAA SCell comprises a storage unit and a processing circuit configured to execute instructions stored in the storage unit. The instructions comprise receiving at least one UL grant from a network in a DL subframe, wherein a UL grant of the at least one UL grant schedules at least one PUSCH transmission associated with a UL HARQ process in at least one UL subframe, and a first timer and a second timer are associated with the UL HARQ process; starting the first timer in a first UL subframe of the at least one UL subframe, if the communication device is not able to perform a PUSCH transmission of the at least one PUSCH transmission in the first UL subframe; starting the second timer, when the first timer expires; and monitoring a PDCCH, when the second timer is running.
