The method according to an embodiment includes generating an Aggregate-Medium Access Control Protocol Data Unit (A-MPDU) including an A-MPDU subframe, the A-MPDU subframe including a Medium Access Control Protocol Data Unit (MPDU) delimiter field; and selecting a type of a guard interval. When the A-MPDU is generated for a plurality of receiving devices, the transmitting device selects a short guard interval only if all of the plurality of receiving devices support the short guard interval. The MPDU delimiter field includes a null field and an MPDU length field, the null field indicates a corresponding A-MPDU subframe is used to pad the A-MPDU, and the MPDU length field indicates a length of an MPDU. The null field is a 1-bit information field."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for multiple frame transmission for supporting MU-MIMO","description":"A method of multi user multiple input multiple output (MIMO) communication in a wireless local area network (WLAN) system; and a transmitting device therefore are discussed.
