Abstract
As a channel busy ratio (CBR) is defined to measure the congestion of a PC5 interface in order to support an effective vehicle-to-everything (V2X) communication, an eNodeB (eNB) transmits CBR information of a sidelink channel to a user equipment (UE) for each resource pool used for V2X communication. The user equipment which has received the CBR information determines if there is a usable CBR and, if it is determined that there is no usable CBR, can use the received CBR information.
Claims14
A method by a wireless device in a wireless communication system, the method comprising:
- receiving, from a network, channel busy ratio (CBR) information for a resource pool;
- and
- performing a sidelink communication based on transmission parameters,
- wherein, based on a CBR measured for the resource pool being available, the transmission parameters are determined based on the measured CBR, and
- wherein, based on the CBR measured for the resource pool being unavailable, the transmission parameters are identified by the CBR information received from the network.
A wireless device in a wireless communication system, the wireless device comprising:
- a memory;
- a transceiver;
- and
- at least one processor, operably coupled to the memory and transceiver, configured to:
- control the transceiver to receive, from a network, channel busy ratio (CBR) information for a resource pool, and
- perform a sidelink communication based on transmission parameters,
- wherein, based on a CBR measured for the resource pool being available, the transmission parameters are determined based on the measured CBR, and
- wherein based on the CBR measured for the resource pool being unavailable, the transmission parameters are identified by the CBR information received from the network.
