In some embodiments, a wireless device determines a TBS for a downlink transmission from a radio access node to the wireless device using a TBS table that supports both a first set of modulation schemes and 256QAM. The TBS table comprises a first set of rows from a preexisting TBS table that supports the first set of modulation schemes but not 256QAM and a second set of rows added to the preexisting TBS table to provide the TBS table, where the second set of rows substantially reuse TBS values from the first set of rows. The wireless device receives the downlink transmission from the radio access node according to the Downlink Control Information (DCI) and the TBS determined for the downlink transmission."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods utilizing an efficient TBS table design for 256QAM in a cellular communications network","description":"Systems and methods relating to the use of a Transport Block Size (TBS) table that supports 256 Quadrature Amplitude Modulation (QAM) in a cellular communications network are disclosed.
