I believe you are talking about the Sidelink shared/control channel which are used for Proximity Services (ProSe) to allow devices in close proximity to detect each other and to communicate directly with each other with the goal to reduce the network load, increase capacity in a given bandwidth and allow communication in areas without network coverage.

Please confirm if you are looking about the same so that it can be answered in detail.

However lookinto the following article for details
