Abstract
The present application generally relates to wireless communication technology. More particularly, it relates to a method and apparatus for controlling sidelink (SL) Quality of Service (QoS). According to one or more embodiments, a method for controlling sidelink (SL) Quality of Service (QoS) comprising the following steps carried out at a User Equipment (UE): a) generating QoS requirement from characteristics for one or more packets to be transmitted via a sidelink; b) determining bearer configuration corresponding to the QoS requirement; and c) performing SL transmission on the basis of the bearer configuration.
Claims30
A method by a User Equipment (UE) for controlling sidelink (SL) Quality of Service (QoS) in a cellular network to which the UE is connected, comprising:
- a) generating QoS requirement from characteristics for one or more packets to be transmitted via a sidelink;
- b) transmitting a bearer request comprising the QoS requirement to a network node;
- and
- c) performing SL transmission on the basis of a bearer configuration received from the network node, wherein the bearer configuration is determined on the basis of the QoS requirement and comprises a mapping relationship between the QoS requirement and a SL Data Radio Bearer (DRB).
A User Equipment (UE) operating in a cellular network with sidelink (SL) Quality of Service (QoS) controlling function, the UE comprising:
- a storage device configured to store a computer program comprising computer instructions;
- and
- a processor coupled to the storage device and configured to execute the computer instructions to, while the UE is connected to the cellular network:
- a) generate QoS requirement from characteristics for one or more packets to be transmitted via a sidelink;
- b) transmit a bearer request comprising the QoS requirement to a network node;
- and
- c) perform SL transmission on the basis of bearer configuration received from the network node, wherein the bearer configuration is determined on the basis of the QoS requirement and comprises a mapping relationship between the QoS requirement and a SL Data Radio Bearer (DRB).
A computer program product for controlling sidelink (SL) Quality of Service (QoS) in a cellular network, the computer program product comprising a non-transitory computer readable storage medium storing computer instructions executable by a processor of a user equipment (UE) to:
- a) generate QoS requirement from characteristics for one or more packets to be transmitted via a sidelink;
- b) transmit a bearer request comprising the QoS requirement to a network node;
- and
- c) perform SL transmission on the basis of bearer configuration received from the network node, wherein the bearer configuration is determined on the basis of the QoS requirement and comprises a mapping relationship between the QoS requirement and a SL Data Radio Bearer (DRB).
