Methods for receiving downlink control information (DCI) are provided herein. A method performed by a wireless transmit/receive unit (WTRU) may include receiving configuration information indicating a location of a monitoring indicator and identifying a first one or more search spaces and a second one or more search spaces. The method may include receiving a first physical downlink control channel (PDCCH) transmission including first DCI, the DCI including the monitoring indicator at the indicated location. The method may include monitoring, based on the monitoring indicator, either the first one or more search spaces or the second one or more search spaces and decoding a second PDCCH transmission detected in either the first one or more search spaces or the second one or more search spaces to receive second DCI.
