Abstract

Systems, apparatuses, and methods are described for wireless communications. A base station may transmit, to a wireless device, one or more radio resource control messages comprising parameters for a discontinuous reception operation. The wireless device may monitor, based on one or more of the parameters, a downlink control channel for downlink control information (DCI). After detecting the DCI, the wireless device may communicate one or more packets.
