CBR Acquisition Through Inter-UE Signaling

A second user equipment of a wireless communication system,

• wherein the second user equipment is configured to operate in a sidelink scenario, in which resources for a sidelink communication over a sidelink channel are allocated or scheduled autonomously by the second user equipment,
• wherein the second user equipment is configured to perform a channel busy ratio measurement on the sidelink channel,
• wherein the second user equipment is configured to transmit, based on the channel busy ratio measurement, a channel busy ratio report to a first user equipment directly via the sidelink.

A transceiver of a wireless communication system,

• wherein the transceiver is configured to receive, from a second user equipment of the wireless communication system a channel busy ratio report describing a channel busy ratio, CBR, of a sidelink channel,
• wherein the transceiver is configured to transmit, to a first user equipment of the wireless communication system, the channel busy ratio report or a further processed version of the channel busy ratio report.

A method for operating a first user equipment of a wireless communication system, the method comprising:

• operating the first user equipment in a sidelink scenario, in which resources for a sidelink communication over a sidelink channel are allocated or scheduled autonomously by the first user equipment, and
• receiving a channel busy ratio report from a second user equipment of the wireless communication system, the channel busy ratio report describing a channel busy ratio, CBR, of the sidelink channel.
