One apparatus includes a transceiver that transmits groupcast data via sidelink communication to a set of UEs and receives negative acknowledgement feedback via sidelink communication from at least one UE of the set, the negative acknowledgement feedback indicating unsuccessful reception of the groupcast data. The apparatus includes a processor that determines a retransmission mode based on a number of UEs sending negative acknowledgement feedback and controls the transceiver to send selectively beamformed retransmission of the groupcast data according to the determined retransmission mode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Selective retransmission of groupcast data","description":"Apparatuses, methods, and systems are disclosed for selective retransmission of groupcast data.
