Resource allocation for sidelink full duplex communications

A method for wireless communications at a base station, comprising:

• receiving, from a user equipment (UE) having multiple transmission reception points, a message comprising a request for a first set of resources for sidelink communications by the UE and an indication of a self-interference measurement between the multiple transmission reception points of the UE using the first set of resources;
• transmitting, to the UE, a first grant scheduling the first set of resources for the UE based at least in part on the message;
• receiving, from the UE, a sidelink feedback message comprising an indication of a second set of sidelink resources that are available for sidelink full duplex communications by the UE;
• and
• transmitting, to the UE, a second grant scheduling a third set of sidelink resources for the sidelink full duplex communications by the UE based at least in part on the sidelink feedback message, wherein the third set of sidelink resources are at least partially overlapping with the second set of sidelink resources.

An apparatus for wireless communications at a user equipment (UE) having multiple transmission reception points, 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 base station, a message comprising a request for a first set of resources for sidelink communications by the UE and an indication of a self-interference measurement by the UE using the first set of resources;
• receive, from the base station, a grant scheduling the first set of resources for the UE based at least in part on the message;
• measure, in the first set of resources, self-interference between a first set of antenna components of a first transmission reception point of the UE configured for transmission and a second set of antenna components of a second transmission reception point of the UE configured for reception;
• transmit, to the base station, a sidelink feedback message comprising an indication of a second set of sidelink resources that are available for sidelink full duplex communications by the UE based at least in part on the measured self-interference;
• receiving, from the base station, a second grant scheduling a third set of sidelink resources for the sidelink full duplex communications by the UE, wherein the third set of sidelink resources are at least partially overlapping with the second set of sidelink resources based at least in part on the sidelink feedback message;
• and
• performing the sidelink full duplex communications in the third set of sidelink resources based at least in part on the second grant.
