An eNB (or other base station) comprising one or more processors may generate a plurality of channel status activation indicators. The eNB's processors may encode the plurality of indicators into a Downlink Control Information (DCI) codeword, may scramble the cyclic redundancy check bits of the DCI with a predetermined sequence, and may generate the DCI codeword to the UE as part of a DCI transmission on a physical control channel. A UE (or other mobile handset) comprising one or more processors may process a DCI transmission from the eNB, the DCI transmission including a DCI codeword. The UE's processors may decode a plurality of channel status activation indicators from the DCI codeword, may check if the cyclic redundancy bits of the DCI are scrambled with a predetermined sequence, and may trigger a plurality of physical layer activation-and-deactivation circuitries based on the plurality of channel status activation indicators.
