Directional sidelink discontinuous reception and operations

A method for wireless communications at a first user equipment (UE), comprising:

• receiving, from a network entity, a configuration message that indicates to extend an active duration of a discontinuous cycle for a sidelink response associated with a configuration for the first UE to perform sidelink communication;
• receiving, within the extended active duration of the discontinuous cycle, a sidelink control message or sidelink measurement signal from a second UE;
• switching, within the extended active duration of the discontinuous cycle and based at least in part on activating a first timer, from a reception mode to a transmission mode based at least in part on receiving the sidelink control message or the sidelink measurement signal;
• and
• transmitting, after switching from the reception mode to the transmission mode and within the extended active duration of the discontinuous cycle based at least in part on the configuration message and activating a second timer, the sidelink response to the sidelink control message or the sidelink measurement signal.

An apparatus for wireless communications at a first user equipment (UE), 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 network entity, a configuration message that indicates to extend an active duration of a discontinuous cycle for a sidelink response associated with a configuration for the first UE to perform sidelink communication;
• transmit, within the extended active duration of the discontinuous cycle, a sidelink control message or sidelink measurement signal to a second UE;
• switch, within the extended active duration of the discontinuous cycle and based at least in part on activating a first timer, from a transmission mode to a reception mode based at least in part on transmitting the sidelink control message or the sidelink measurement signal;
• and
• monitor, after switching from the transmission mode to the reception mode and within the extended active duration of the discontinuous cycle based at least in part on the configuration and activating a second timer, for the sidelink response to the sidelink control message or the sidelink measurement signal from the second UE.
