Methods and apparatus for inter-ue coordinated resource allocation in wireless communication

A method, performed by a receiving user equipment (UE) in a wireless communication system comprising:

• establishing a sidelink session with a transmitting UE;
• performing a local sensing;
• receiving a Physical Sidelink Control Channel (PSCCH), a Physical Sidelink Shared Channel (PSSCH), and reserved multiple resources from the transmitting UE, wherein the transmitting UE reserves the reserved multiple resources;
• determining whether a coordination message is triggered;
• in response to the coordination message being triggered, transmitting the coordination message indicating whether a collision occurs among the reserved multiple resources, to the transmitting UE.

A baseband processor configured to cause a transmitting user equipment (UE) to perform operations comprising:

• establishing a sidelink session with a receiving UE;
• performing a sensing and a resource selection;
• determining whether to trigger a coordination message;
• transmitting a PSCCH and a PSSCH to the receiving UE indicating reserved multiple resources by the transmitting UE, wherein the transmitting UE reserves multiple resources
• transmitting, to the receiving UE, an indication to trigger the coordination message;
• and performing resource reselection based on the coordination message.
