Sidelink reference signal and measurement report sharing

A second user equipment (UE) for wireless communication, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to:
• receive, from a first UE, information indicating a reference signal and a measurement report for a first sidelink between the first UE and the second UE;
• transmit or receive the reference signal on a second sidelink between the first UE and the second UE;
• and
• transmit or receive the measurement report on the second sidelink;
• wherein the information is dedicated for sidelink channel state information (CSI) reporting that is to be shared among multiple sidelinks between the first UE and the second UE.

A method of wireless communication performed by a first user equipment (UE), comprising:

• generating information indicating a reference signal and a measurement report for a first sidelink between the first UE and a second UE;
• and
• using the information for a second sidelink between the first UE and the second UE;
• wherein the reference signal is dedicated for sidelink channel state information (CSI) reporting that is to be shared among multiple sidelinks between the first UE and the second UE.

• generate information indicating a reference signal and a measurement report for a first sidelink between the first UE and a second UE;
• and
• use the information for a second sidelink between the first UE and the second UE;
• wherein:
• the information indicating the reference signal includes a transmission configuration indicator (TCI) state for the reference signal or a configuration for the reference signal;
• and
• the one or more processors are configured to transmit or receive a medium access control control element (MAC CE) that activates the TCI state for the first sidelink and that includes a source identifier (ID) and a destination ID of the second sidelink;
• or
• the one or more processors, to transmit the information that includes the TCI state, are configured to transmit the information that includes the TCI state in a TCI state list on a sidelink between the first UE and the second UE that is dedicated for sharing the TCI state list.
