Abstract
A method and apparatus for sidelink resource handling for central unit (CU)-distributed unit (DU) split based vehicle-to-everything (V2X) communication is provided. A gNB central unit (gNB-CU) in a wireless communication system receives, from a wireless device, information related to a radio access technology (RAT) for which a sidelink resource is requested. The gNB-CU transmits, to a gNB distributed unit (gNB-DU), the information related to the RAT for sidelink resource allocation.
Claims16
A method performed by a gNB central unit (gNB-CU) operating in a wireless communication system, the method comprising:
- receiving, from a wireless device, a sidelink resource request for a specific radio access technology (RAT);
- transmitting, to a gNB distributed unit (gNB-DU), the sidelink resource request for the specific RAT;
- receiving, from the gNB-DU, a sidelink resource for the specific RAT, which is configured by the gNB-DU based on the sidelink resource request for the specific RAT;
- and
- transmitting, to the wireless device, the sidelink resource for the specific RAT.
A gNB central unit (gNB-CU) operating in a wireless communication system, the method comprising:
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
- receiving, from a wireless device, a sidelink resource request for a specific radio access technology (RAT);
- transmitting, to a gNB distributed unit (gNB-DU), sidelink resource request for the specific RAT;
- receiving, from the gNB-DU, a sidelink resource for the specific RAT, which is configured by the gNB-DU based on the sidelink resource request for the specific RAT;
- and
- transmitting, to the wireless device, the sidelink resource for the specific RAT.

A user equipment (UE) operating in a wireless communication system, the method comprising:
- transmitting, to a gNB central unit (gNB-CU), a sidelink resource request for a specific radio access technology (RAT);
- and
- receiving, from the gNB-CU, a sidelink resource for the specific RAT, which is configured by a gNB distributed unit (DU) based on the sidelink resource request for the specific RAT forwarded to the gNB-DU by the gNB-CU.
