1. A method for operating an electronic communication device, the method comprising:
determining, in an active mode of the electronic communication device and via a processing unit, a state associated with a direct mode radio channel;
determining, in the active mode, at least one subset of a plurality of radio resources of the direct mode radio channel based on the determined state;
determining, in the active mode, an active mode time period based on the determined state associated with the direct mode radio channel;
determining an end of the active mode time period;
initiating a sleep mode upon the determination of the end of the active mode time period;
determining, in the sleep mode, a sleep mode time period based on the determined state associated with the direct mode radio channel;
determining an end of the sleep mode time period;
initiating the active mode upon the determination of the end of the sleep mode time period, and
performing a cross-slot scheduling including
receiving, in the active mode, first sidelink physical channel information,
decoding a first stage, a second stage, or both, of a first sidelink control information,
determining, based on the decoded information, a necessity to decode a further transmission associated with a reservation in the first sidelink control information based on an indication in the first sidelink control information for a first physical sidelink shared channel associated with the first sidelink control information,
performing a micro-sleep and skipping decoding the first physical sidelink shared channel, and
in response to determining that it is necessary to decode the further transmission, decoding a second retransmission or a third retransmission of the first sidelink physical channel information following the micro-sleep and the skipping of decoding the first physical sidelink shared channel.
