1. A method comprising:
receiving, by a wireless user device from a base station, one or more messages comprising information of a resource allocation mode for direct data transmission between wireless user devices;
determining, by the wireless user device, a radio link failure (RLF) associated with a radio resource control (RRC) connection; and
based on the determined RLF:
canceling buffer status reports (BSRs) for direct data transmission, wherein the canceled BSRs for direct data transmission are associated with at least one direct data transmission, between wireless user devices, scheduled by the base station;
selecting, based on a configuration parameter indicating a plurality of resources of a resource pool via which the wireless user device is allowed to transmit data to at least one wireless user device in an exceptional condition, at least one resource associated with the exceptional condition; and
transmitting, via the at least one resource associated with the exceptional condition, data to a second wireless user device.
