Dynamic time division duplexing for enhanced sidelink control signaling

An apparatus for wireless communications at a first wireless device, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a second wireless device and via a sidelink communication link, sidelink control information comprising a first scheduling for an uplink control transmission from the first wireless device to the second wireless device during a first slot;
• decode at least a portion of the sidelink control information, the sidelink control information comprising an indication of an operating mode of the second wireless device in the first slot, wherein the indication of the operating mode is received in a temporally first portion of the sidelink control information;
• and
• apply a second scheduling for the uplink control transmission different from the first scheduling, the second scheduling based at least in part on the operating mode of the second wireless device in the first slot.

An apparatus for wireless communications at a second wireless device, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• transmit, to a first wireless device and via a sidelink communication link in a first slot, sidelink control information comprising a scheduling for an uplink control transmission from the first wireless device to the second wireless device during a second slot, wherein the sidelink control information further comprises an indication of an operating mode of the second wireless device in the second slot and is transmitted in a temporally first portion of the sidelink control information;
• and
• switch the operating mode of the second wireless device to receive the uplink control transmission in the second slot in accordance with the scheduling.
