The multi-layer transmission comprising multiple layers each having a different robustness on the radio frequency. As to a method aspect of the technique, a contention procedure is performed with respect to each of a plurality of access classes, ACs, for accessing the radio frequency. The multi-layer transmission is performed upon success of the contention procedure of at least one of the ACs. In a transmission opportunity defined by the successful contention procedure, data associated with the successful AC is transmitted on a main layer of the multi-layer transmission simultaneously with data associated with at least one further AC on at least one further layer, which is less robust than the main layer of the multi-layer transmission."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Contention-based multi-layer transmission","description":"A technique for performing a multi-layer transmission of data on a radio frequency is described.
