Abstract:
1. A packet transmission method for a wireless local area network wherein a source transmits data to a destination, comprising: performing a first initialization transaction to initialize a first burst transmission, wherein the first initialization transaction consists of the source delivering a first clear-to-send (CTS) frame; initializing the first burst transmission at one SIFS interval after completion of the initialization transaction, wherein said first burst transmission does not deliver any CTS frame; delivering a plurality of data frames from the source to the destination; awaiting an ACK frame from the destination within one SIFS interval when each data frame is delivered; and delivering the successive data frame at one SIFS interval after upon receipt of the ACK frame when a successive data frame is ready, and repeating the awaiting step, wherein upon completion of the first burst transmission, the source holding one SIFS interval and performs a second initialization transaction to initialize a second burst transmission, said the second initialization transaction consists of the source delivering a second clear-to-send (CTS) frame; and the first CTS frame comprises a network allocation vector (NAV) reserving the medium for a duration beginning at the falling edge of the first CTS frame and ending at the falling edge of the second CTS frame.
