In some systems, a first user equipment (UE) may operate in accordance with a multi-user (MU) multiple input-multiple output (MIMO) communication mode and may communicate with multiple other UEs over a same physical sidelink shared channel (PSSCH) resource. In some implementations, the first UE may transmit an indication of an MU-unicast mode for multiple sidelink transmissions to the multiple other UEs and may transmit the multiple sidelink transmissions to the multiple other UEs over the same PSSCH resource. In such implementations, the multiple other UEs may select physical sidelink feedback channel (PSFCH) resources to transmit feedback associated with the multiple sidelink transmissions in accordance with a PSFCH resource selection procedure associated with the MU-unicast mode. In accordance with the PSFCH resource selection procedure, the multiple other UEs may each select different PSFCH resources for their respective feedback transmissions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Feedback designs for multi-user multiple input-multiple output sidelink communication","description":"Methods, systems, and devices for wireless communications are described.
