Abstract
Systems and methods provide solutions for delay and interruption requirements for vehicle-to-everything (V2X) sidelink carrier aggregation (CA). For example, when any number of component carriers is added for V2X CA, a user equipment (UE) capable of V2X sidelink communication is allowed an interruption of up to two subframes to the cellular network. The interruption may be for both uplink and downlink of a serving cell or primary cell.
Claims12
A method for a user equipment (UE), the method comprising:
- decoding a radio resource control (RRC) signal comprising a component carrier addition or release command for vehicle-to-everything (V2X) carrier aggregation (CA) in a wireless wide area network (WAN);
- determining that the UE is configured for V2X sidelink communication;
- and
- in response to the component carrier addition or release command and the determination that the UE is configured for V2X sidelink communication, interrupting communications with the WAN for up to two subframes for radio frequency (RF) chain configuration.
1 more element
An apparatus for a mobile communication system, the apparatus comprising:
- means to determine that a user equipment (UE) is configured in a connected mode wherein a wireless wide area network (WAN) allocates time and frequency transmission resources to the UE;
- means to process a radio resource control (RRC) connection reconfiguration message corresponding to a vehicle-to-everything (V2X) carrier addition or release command, the RRC connection reconfiguration message comprising dedicated configuration information for V2X sidelink communication in a subframe n from the WAN;
- and
- means to, in response to the V2X carrier addition or release command, add or release one or more V2X component carriers no later than an end of WAN subframe n+21+N, where N is a number of the one or more V2X component carriers added or released.
