1. A method of operating a terminal device, comprising:
configuring a data connection on a wireless link between the terminal device and a network based on a first control signal native to a first layer of a transmission protocol stack associated with the wireless link,
participating in a data communication via the data connection,
receiving a second control signal native to a second layer of the transmission protocol stack, the second layer being arranged lower in hierarchy of the transmission protocol stack than the first layer,
in response to receiving the second control signal: activating a connected mode discontinuous reception for the data communication, and
during the connected mode discontinuous reception, suspending monitoring a downlink control channel, wherein the data connection and a configuration for the data connection set by RRC control signaling are maintained during the connected mode discontinuous reception,
wherein the second layer is implemented by the Physical Layer of the transmission protocol stack,
wherein the connected mode discontinuous reception activated in response to the second control signal has a temporal validity, and
wherein the second control signal is indicative of a timing of the discontinuous reception.
