Claim of US Patent No. 10,397,977

1. A method for communicating by an internet of things (IoT) device in a wireless communication system, the method comprising:configuring a length of a drxCycle;
configuring a starting subframe of the drxCycle;
configuring, by the IoT device, a length of a first timer specifying a time in which the IoT device remains in an active state of discontinuous reception (DRX) operation;
starting, by the IoT device, the first timer when a second timer expires;
monitoring, by the IoT device, a physical downlink control channel (PDCCH); and
stopping, by the IoT device, the first timer when the monitored PDCCH indicates a transmission for the IoT device,
wherein the starting subframe of the drxCycle is determined by [(SFN*10)+sf?SS_Offset]modulo DRX=drxStartOffset modulo DRX where an SFN is a system frame number, an sf is a subframe number within a system frame, an SS_Offset is a PDCCH search space offset from a subframe 0, a DRX is a length of a drxCycle in a subframe, and a drxStartOffset is an offset of the starting subframe of the drxCycle from the subframe 0.
