Abstract
An apparatus of a first user equipment (UE) comprises one or more baseband processors to generate a message to indicate to a second UE that the first UE intends to establish a new radio (NR) sidelink connection for enhanced vehicle-to-everything (eV2X) services, and to process a response from the second UE regarding the message. The apparatus can include a memory to store the message.
Claims20
A processor of a first user equipment (UE) configured to perform operations, the operations comprising:
- transmitting a radio resource control (RRC) message to a second UE, the RRC message comprising an indication that the first UE intends to establish a new radio (NR) sidelink connection for a vehicle-to-everything (V2X) service, wherein the indication is an RRC information element (IE) comprising at least quality of service (QoS) related parameters for the NR sidelink connection, a source ID for the first UE, a destination ID for the second UE, a V2X service ID for the V2X service and security related information for the 5G NR sidelink comprising one or more security keys;
- receiving a response to the RRC message from the second UE;
- and
- transmitting keep alive signaling (KAS) to the second UE, wherein the KAS comprises at least one of i) an updated QoS related parameter, ii) an updated source ID for the first UE, or iii) an updated destination ID for the second UE.
A first user equipment (UE), comprising:
- a transceiver configured to communicate with a network;
- and
- a processor communicatively coupled to the transceiver and configured to perform operations, the operations comprising:
- generating a radio resource control (RRC) message for a second UE comprising an indication that the first UE intends to establish a new radio (NR) sidelink connection for a vehicle-to-everything (V2X) service, wherein the indication is an RRC information element (IE) comprising at least quality of service (QoS) related parameters for the NR sidelink connection, a source ID for the first UE, a destination ID for the second UE, a V2X service ID for the V2X service and security related information for the 5G NR sidelink comprising one or more security keys;
- processing a response to the RRC message from the second UE;
- and
- generating keep alive signaling (KAS) for the second UE, wherein the KAS comprises at least one of i) an updated QoS related parameter, ii) an updated source ID for the first UE, or iii) an updated destination ID for the second UE.
A method performed by a first user equipment (UE), comprising:
- transmitting a radio resource control (RRC) message to a second UE, the RRC message comprising an indication that the first UE intends to establish a new radio (NR) sidelink connection for a vehicle-to-everything (V2X) service, wherein the indication is an RRC information element (IE) comprising at least quality of service (QOS) related parameters for the NR sidelink connection, a source ID for the first UE, a destination ID for the second UE, a V2X service ID for the V2X service and security related information for the 5G NR sidelink comprising one or more security keys;
- receiving a response to the RRC message from the second UE;
- and
- transmitting keep alive signaling (KAS) to the second UE, wherein the KAS comprises at least one of i) an updated QoS related parameter, ii) an updated source ID for the first UE, or iii) an updated destination ID for the second UE.
