Apparatus and method for reducing delay of buffering in short range wireless communication system

Abstract

According to various embodiments of the present disclosure, a method of operating a first apparatus in a short-range wireless communication system, the first apparatus includes: a first processor corresponding to a host stack; a second processor corresponding to a first controller stack; a memory; and a transceiver, wherein the host stack and the first controller stack are connected through a host controller interface (HCI), the method includes: in relation to data transport from the first controller stack of the first apparatus to a second controller stack of a second apparatus, transporting, from the first processor to the second processor, HCI command information configured so that there is no buffering in the first controller stack; transporting a plurality of service data units (SDUs) generated by the first processor to the second processor—each of the plurality of SDUs is transported to the second processor apart at each configured sub interval-; and based on the HCI command information, transporting, by the transceiver, each of a plurality of protocol data units (PDUs) based on each of the plurality of SDUs to the second apparatus without buffering after each of the plurality of SDUs is received by the second processor, wherein transport of the plurality of PDUs is performed within one isochronous event.
