Resource management techniques for full-duplex and half-duplex vehicle-to-everything systems

An apparatus for wireless communications at a first device that supports half-duplex communications in a wireless network, comprising:

• a processor;
• and
• memory coupled to the processor, the processor configured to:
• transmit a first sidelink control channel during a set of time resources, the first sidelink control channel comprising scheduling information for transmission of a sidelink data channel by the first device via a first set of time-frequency resources;
• receive, from a second device, an indication that the first set of time-frequency resources at least partially overlaps with a second set of time-frequency resources reserved by the second device;
• select a third set of time-frequency resources that is different from the second set of time-frequency resources based at least in part on the received indication;
• and
• transmit, to the second device, an updated sidelink control channel comprising updated scheduling information for transmission of the sidelink data channel by the first device via the third set of time-frequency resources based at least in part on the selected third set of time-frequency resources.

• transmitting a first sidelink control channel during a set of time resources, the first sidelink control channel comprising scheduling information for transmission of a first sidelink data channel by the first device via a first set of time-frequency resources;
• receiving, from a second device, a second sidelink control channel during the set of time resources, the second sidelink control channel comprising scheduling information for transmission of a second sidelink data channel by the second device via a second set of time-frequency resources;
• performing a resource selection procedure based at least in part on the first set of time-frequency resources at least partially overlapping with the second set of time-frequency resources;
• and
• transmitting, to the second device, an updated sidelink control channel comprising updated scheduling information for transmission of the first sidelink data channel by the first device via a third set of time-frequency resources based at least in part on the resource selection procedure.
