A UE may, after establishing an RRC connection with a base station, transmit, to the base station, V2X connection information. The V2X connection information may include a V2X identifier associated with the UE and a V2X identifier associated with a target UE. The UE may receive, from the base station, a side-link configuration for data transmission with the target UE. The side-link configuration may include a resource allocation defined in time and frequency (e.g., a transmit/receive pool). The UE may communicate with the target UE using the resource allocation included in the side-link configuration. ## Claims ### Claim 1 A user equipment device (UE), comprising: at least one antenna; at least one radio, wherein the at least one radio is configured to perform cellular communication using at least one radio access technology (RAT); and one or more processors coupled to the at least one radio, wherein the one or more processors and the at least one radio are configured to perform communications; and wherein the one or more processors are configured to cause the UE to: establish a radio resource control (RRC) connection with a first base station, including sharing, with the first base station, vehicle-to-everything (V2X) information including a destination identifier associated with an other UE, V2X capabilities of the UE, and associated cell information; perform PC5 data transmissions with the other UE, wherein the other UE has an RRC connection with a second base station; receive, during the PC5 data transmissions, a handover command from the first base station, wherein the handover command includes an indication to continue the PC5 data transmissions in an exceptional pool during a handover procedure to the second base station; and establish an RRC connection with the second base station as part of the handover procedure. ### Claim 2 (depends on 1) The UE of claim 1, wherein the one or more processors are further configured to cause the UE to: resume, after completion of the handover procedure, the PC5 data transmissions with the other UE in a transmit pool. ### Claim 3 (depends on 1) The UE of claim 1, wherein the one or more processors are further configured to cause the UE to: receive, from the first base station, a side-link configuration for PC5 data transmissions with the other UE. ### Claim 4 (depends on 3) The UE of claim 3, wherein the side-link configuration includes a resource allocation defined in time and frequency. ### Claim 5 (depends on 4) The UE of claim 4 wherein the side-link configuration further includes at least one of: layer two resource blocks;
