Abstract
The present disclosure relates to 5G (5th generation) or pre-5G communication systems to support the higher data rate after 4G (4th generation) communication systems such as LTE (Long Term Evolution). The present disclosure provides an apparatus and a method for effectively selecting a transmission carrier in a wireless communication system. The present disclosure relates to an operating method of a terminal in a wireless communication system, which including receiving configuration information from a base station and selecting a transmission carrier and a resource pool on the basis of the configuration information.
Claims18
A method for operating performed by a terminal in a wireless communication system, the method comprising:
- receiving, from a base station, information on a first threshold value of a channel busy ratio (CBR) and a second threshold value of the CBR;
- measuring a first CBR for a serving carrier and a second CBR for at least one candidate carrier;
- in case that the first CBR is higher than the first threshold value and the second CBR is lower than the second threshold value, selecting a carrier having a lowest CBR among the at least one candidate carrier;
- selecting at least one resource of a resource pool associated with the carrier;
- and
- transmitting data based on the selected at least one resource.
A terminal in a wireless communication system, the terminal comprising:
- a transceiver;
- and
- a processor coupled with the transceiver and configured to:
- receive, from a base station, information on a first threshold value of a channel busy ratio (CBR) and a second threshold value of the CBR,
- measure a first CBR for a serving carrier and a second CBR for at least one candidate carrier,
- in case that the first CBR is higher than the first threshold value and the second CBR is lower than the second threshold value, select a carrier having a lowest CBR among the at least one candidate carrier,
- select at least one resource of a resource pool associated with the carrier, and
- transmit data based on the selected at least one resource.
A method performed by a base station in a wireless communication system, the method comprising:
- transmitting, to a terminal, information on a first threshold value for a first channel busy ratio (CBR) from a serving carrier and a second threshold value for a second CBR from at least one candidate carrier,
- wherein, in case that the first CBR is higher than the first threshold value and the second CBR is lower than the second threshold value, a carrier having a lowest CBR is selected among the at least one candidate carrier, and data is received based on selected at least one resource of a resource pool associated with the carrier.
A base station in a wireless communication system, the base station comprising:
- a transceiver;
- and
- a processor coupled with the transceiver and configured to:
- transmit, to a terminal, information on a first threshold value for a first channel busy ratio (CBR) from a serving carrier and a second threshold value for a second CBR from at least one candidate carrier,
- wherein, in case that the first CBR is higher than the first threshold value and the second CBR is lower than the second threshold value, a carrier having a lowest CBR is selected among the at least one candidate carrier, and data is received based on selected at least one resource of a resource pool associated with the carrier.
