Multi-anchor sidelink quasi-colocation indication and configuration for enhanced positioning and sensing

A method at a receiving user equipment (UE) for utilizing multi-anchor sidelink quasi-colocation (mSL-QCL) information, the method comprising:

• wirelessly receiving, at the receiving UE, the mSL-QCL information from a base device, wherein the mSL-QCL information is indicative of a quali-colocation (QCL) relationship between a first wireless reference signal transmitted by a first sidelink (SL) anchor and a second wireless reference signal transmitted by a second SL anchor, and wherein:
• the first SL anchor and the second SL anchor comprise UEs separate from the receiving UE, and
• the first wireless reference signal and the second wireless reference signal are transmitted for positioning of the receiving UE, performing radio frequency (RF) sensing, or both;
• and
• wirelessly measuring the first wireless reference signal, the second wireless reference signal, or both, based at least in part on the mSL-QCL information.

A base device for configuring a receiving user equipment (UE) for multi-anchor sidelink quasi-colocation (mSL-QCL) information, the base device comprising:

• a transceiver;
• a memory;
• and
• one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to:
• determine a quali-colocation (QCL) relation between a first wireless reference signal transmitted by a first sidelink (SL) anchor and a second wireless reference signal transmitted by a second SL anchor, wherein:
• the first SL anchor and the second SL anchor comprise UEs separate from the receiving UE, and
• the first wireless reference signal and the second wireless reference signal are transmitted for positioning of the receiving UE, performing radio frequency (RF) sensing, or both;
• and
• wirelessly send, via the transceiver to the receiving UE, the mSL-QCL information, wherein the mSL-QCL information is indicative of the QCL relation between the first wireless reference signal and the second wireless reference signal.
