Abstract
A communication method of a first sidelink terminal in a wireless communication system is provided. The communication method includes obtaining sidelink radio bearer configuration information, identifying default sidelink radio bearer information in the sidelink radio bearer configuration information, and transmitting data to a base station or a second sidelink terminal based on the default sidelink radio bearer information.
Claims18
A communication method of a first sidelink terminal in a wireless communication system, the communication method comprising:
- receiving sidelink radio bearer configuration information including default sidelink radio bearer information indicating a default sidelink radio bearer for a sidelink QoS flow and priority information comprising a priority value for sidelink data transmission;
- and
- transmitting, to a second sidelink terminal, sidelink data prior to uplink data identified to be transmitted to a base station, based on the default sidelink radio bearer information, in case that the priority value for the sidelink data transmission is less than a priority threshold value for a sidelink and a priority value for uplink data transmission is greater than or equal to a priority threshold value for an uplink,
- wherein the priority value for the uplink data transmission and the priority threshold value for the sidelink and the uplink are configured via a radio resource control (RRC) signal.
A first sidelink terminal of a wireless communication system, the first sidelink terminal comprising:
- a transceiver;
- and
- a processor coupled to the transceiver and configured to:
- receive sidelink radio bearer configuration information including default sidelink radio bearer information indicating a default sidelink radio bearer for a sidelink QoS flow and priority information comprising a priority value for sidelink data transmission, and
- transmit, to a second sidelink terminal, sidelink data prior to uplink data identified to be transmitted to a base station, based on the default sidelink radio bearer information, in case that the priority value for the sidelink data transmission is less than a priority threshold value for a sidelink and a priority value for uplink data transmission is greater than or equal to a priority threshold value for an uplink,
- wherein the priority value for the uplink data transmission and the priority threshold value for the sidelink and the uplink are configured via a radio resource control (RRC) signal.
