Resource allocation and configuration for broadcast and unicast operation over sidelink for NR V2X
An apparatus of a user equipment (UE) comprises one or more baseband processors to configure a set of resources for New Radio (NR) vehicle-to-everything (V2X) transmission over sidelink for communication with one or more other UEs, and to allocate the resources for transmitting one or more packets from an NR network to the one or more other UEs via the sidelink. The apparatus can include a memory to store the configuration of resources.
1. An apparatus of a user equipment (UE), comprising:
one or more baseband processors to configure a set of resources for New Radio (NR) vehicle-to-everything (V2X) transmission over sidelink for communication with one or more other UEs, to allocate the set of resources for transmitting one or more packets from an NR network to the one or more other UEs via the sidelink, to determine whether a resource pool for the NR V2X transmission is unavailable, when the resource pool for the NR V2X transmission is unavailable, select the set of resources from an exception resource pool and when the resource pool for the NR V2X transmission is available, select the set of resources to be configured from the resource pool for the NR V2X transmission, wherein a first resource pool, in the set of resources, is used for unicast communication and a second resource pool, in the set of resources, is used for broadcast communication and wherein the first resource pool is unique to a specific unicast link; and
a memory to store the configured set of resources.
2. The apparatus of claim 1 , wherein the UE is to select the set of resources to be configured autonomously from the NR network.
3. The apparatus of claim 1 , wherein the exception resource pool is used for handover.
4. The apparatus of claim 1 , wherein the exception resource pool is used for radio link failure.
5. The apparatus of claim 1 , wherein a first congestion control mechanism is used for the unicast communication, and a second congestion control mechanism is used for the broadcast communication.
6. One or more non-transitory machine readable media having instructions stored thereon that, when executed by an apparatus of a user equipment (UE), result in:
configuring a set of resources for New Radio (NR) vehicle-to-everything (V2X) transmission over sidelink for communication with one or more other UEs;
allocating the set of resources for transmitting one or more packets from an NR network to the one or more other UEs via the sidelink;
determining whether a resource pool for the NR V2X transmission is unavailable;
when the resource pool for the NR V2X transmission is unavailable, selecting the set of resources from an exception resource pool; and
when the resource pool for the NR V2X transmission is available, select the set of resources to be configured from the resource pool for the NR V2X transmission, wherein a first resource pool, in the first resource pool, is used for unicast communication and a second resource pool, in the resource pool, is used for broadcast communication and wherein the first resource pool is unique to a specific unicast link.
7. The one or more non-transitory machine readable media of claim 6 , wherein the UE is to select the set of resources to be configured autonomously from the NR network.
8. The one or more non-transitory machine readable media of claim 6 , wherein the exception resource pool is used for handover.
9. The one or more non-transitory machine readable media of claim 6 , wherein the exception resource pool is used for radio link failure.
10. The one or more non-transitory machine readable media of claim 6 , wherein a first congestion control mechanism is used for the unicast communication, and a second congestion control mechanism is used for the broadcast communication.
