Abstract (en)

[origin: WO2019090605A1] Various communication systems may benefit from improved carrier aggregation. For example, certain communication systems may benefit from improved sidelink carrier aggregation in vehicle-to-everything communication. A method, in certain embodiments, may include receiving at a user equipment a sidelink carrier aggregation configuration. The sidelink carrier aggregation configuration may include a timing offset. The method may also include determining to transmit data using the sidelink carrier aggregation on a resource of a first carrier and a resource of a second carrier based on the timing offset and a timing of the resource of the first carrier. In addition, the method may include transmitting data from the user equipment using the sidelink carrier aggregation on the resource of the first carrier and the resource of the second carrier.
