US Patent 10420165 Discontinuous reception in a wireless device and wireless network

A wireless device receives a first downlink control information (DCI). The first DCI comprises: a first trigger field indicating that the first DCI is triggered in response to a second DCI indicating a second trigger; and a field indicating a validation duration for receiving the second DCI via a cell. A discontinuous reception (DRX) process determines that a medium access control (MAC) entity is not in an Active Time. The MAC entity, during at least a portion of the validation duration, monitors a control channel for the second trigger on the cell even if the MAC entity is not in the Active Time.
