he scheduled resource allocation or UE autonomous resource selection according to eNB configuration. When the UE is out-of- coverage on the frequency used for V2X sidelink communication and if the eNB does not provide V2X sidelink configuration for that frequency, the UE may use a set of transmission and reception resource pools preconfigured in the UE. The V2X sidelink communication resources are not shared with other non-V2X data transmitted over sidelink. An RRC_CONNECTED UE may send a sidelink UE information message to the serving cell, when it wishes to establish V2X sidelink communication in order to request sidelink resources If the UE is configured by upper layers to receive V2X sidelink communication and V2X sidelink reception resource pools are provided, then the UE will receive sidelink communi- cation on the allocated resources. The reception of V2X sidelink communication on differ- ent carriers or from different PLMNs can be supported by incorporating multiple receivers in the UE. For sidelink SPS, up to eight SPS configurations with different parameters can be configured by the eNB and all SPS configurations can be simultaneously active. The activation/deactivation of SPS configuration is signaled via PDCCH by the eNB. The exist- ing logical channel prioritization based on PPPP is used for sidelink SPS. The UE can pro- vide supplementary information to the eNB which configures the reporting of such information for V2X sidelink communication. The latter information includes traffic charac- teristic parameters (e.g., a set of preferred SPS interval, timing offset with respect to sub- frame 0 of the SFN 0, PPPP and maximum TB size based on the observed traffic pattern) related to the SPS configuration. The UE supplementary information can be reported regard- less of whether SPS is configured. Triggering of UE supplementary information transmis- sion is implementation specific. For instance, the UE can report its supplementary information when a change in estimated periodicity and/or timing offset of pa
