Claim
1. A method, at a User Equipment (UE), for obtaining configuration information for one or more Sidelink Radio bearers (SL-RBs) used for sidelink communication, the method comprising:
transmitting a sidelink (SL) configuration request, the SL configuration request comprising UE capability information and service information associated with a requested ultra-reliable low latency (URLL) vehicle-to-anything (V2X) service;
receiving a sidelink configuration response sent the sidelink configuration response comprising the configuration information for one or more SL-RBs associated with the requested URLL V2X service; and
transmitting data associated with the requested URLL V2X service over the one or more SL-RBs using the configuration information.
2. The method of claim 1, wherein the configuration request associated with the requested URLL V2X service comprises at least one of:
an identifier of the requested URLL V2X service;
an identifier of a destination UE to be associated with the requested URLL V2X service;
an identifier of a destination UE group to be associated with the requested URLL V2X service;
quality of service (QoS) indicators to be associated with the requested URLL V2X service
UE capabilities associated with the requested URLL V2X service;
preferred radio resources associated with the requested URLL V2X service.
3. The method of claim 1, wherein the configuration information for the requested URLL V2X service comprises a mapping of the requested URLL V2X service to a set of component carriers.
4. The method of claim 1, wherein the configuration information for the requested URLL V2X service comprises connection type information indicative of a connection type supported by the connection type comprising one of unicast, groupcast or broadcast transmission.
5. The method of claim 1, wherein the configuration information for the requested URLL V2X service comprises quality of service (QoS1 class information indicative of the QoS supported by the one or more SL-RBs.
6. The method of claim 5, wherein one or more QoS flows can be mapped to a QoS class.
7. The method of claim 1, wherein the configuration information for the requested URLL V2X service includes one or more of:
an identifier of the SL-RB;
packet filtering rules for mapping a data packet to an SL-RB;
parameters corresponding to the layer 2 radio link protocol stack associated with the SL-RB;
mapping rules to map between the SL-RBs and SL carriers;
SL carrier information; and
resource pool information.
8. The method of claim 1 wherein the UE capability information includes a set of parameters comprising at least one of:
an identifier of UE;
supported resource scheduling and communication modes;
supported radio access technologies (RAT), and radio frequency capability;
supported Sidelink carrier frequency bands;
UE class information corresponding to maximum transmit power supported;
number of transmitter and receiver chains supported; and
channel sensing, measurement and reporting capability.
9. The method of claim 1 wherein the configuration information for the requested URLL V2X service includes packet duplication configuration information, the packet duplication configuration information comprises:
an indication whether packet duplication is to be activated; and
mapping restrictions when mapping the duplicate packets to different SL carriers.
10. The method of claim 1, wherein the requested URLL V2X service comprises one or more of: platooning, remote driving, and automated driving.
11. A method of claim 1, wherein the sidelink configuration request is an RRC message transmitted to a radio access network (RAN) node and the sidelink configuration response is an RRC message received from a RAN node.
12. The method of claim 1, wherein the sidelink configuration request is transmitted over a SL discovery channel and the sidelink configuration response is received over a SL discovery channel.
13. A method, by a RAN node, for providing configuration information for one or more Sidelink Radio bearers (SL-RBs) used for sidelink communication with one or more UEs, the method comprising of:
