Abstract
A method and apparatus are disclosed from the perspective of a first User Equipment (UE) in RRC_CONNECTED to request sidelink resources. In one embodiment, the method transmits a first RRC (Radio Resource Control) message to a network node, wherein a presence of a sidelink QoS (Quality of Service) information list in the first RRC message is optional.
Claims16
A method for a first UE (User Equipment) in RRC_CONNECTED to request sidelink resources, comprising:
- transmitting a first RRC (Radio Resource Control) message to a network node, wherein a presence of a sidelink QoS (Quality of Service) information list in the first RRC message is optional,
- wherein the first RRC message is used to:
- request sidelink resources for transmitting traffic of a V2X (Vehicle-to-Everything) service to a second UE;
- or
- request sidelink resources for transmitting a PC5-S message used to request establishment of a PC5 unicast link with the second UE,
- wherein the sidelink QoS information list is present in the first RRC message transmitted to the network node if the first RRC message is used to request sidelink resources for transmitting traffic of the V2X service to the second UE, and
- wherein the sidelink QoS information list is absent in the first RRC message transmitted to the network node if the first RRC message is used to request sidelink resources for transmitting the PC5-S message used to request establishment of the PC5 unicast link with the second UE.

A first UE (User Equipment), comprising:
- a control circuit;
- a processor installed in the control circuit;
- and
- a memory installed in the control circuit and operatively coupled to the processor;
- wherein the processor is configured to execute a program code stored in the memory to:
- transmit a first RRC (Radio Resource Control) message to a network node, wherein a presence of a sidelink QoS (Quality of Service) information list in the first RRC message is optional,
- wherein the first RRC message is used to:
- request sidelink resources for transmitting traffic of a V2X (Vehicle-to-Everything) service to a second UE;
- or
- request sidelink resources for transmitting a PC5-S message used to request establishment of a PC5 unicast link with the second UE,
- wherein the sidelink QoS information list is present in the first RRC message transmitted to the network node if the first RRC message is used to request sidelink resources for transmitting traffic of the V2X service to the second UE, and
- wherein the sidelink QoS information list is absent in the first RRC message transmitted to the network node if the first RRC message is used to request sidelink resources for transmitting the PC5-S message used to request establishment of the PC5 unicast link with the second UE.
