METHOD FOR TRANSMITTING PPDU IN WIRELESS LOCAL AREA NETWORK AND APPARATUS FOR THE SAME

摘要

A method and device for receiving a data block in a wireless communication system, the method performed by a receiver. The method includes: receiving a physical layer protocol data unit (PPDU) from a transmitter over an operating channel, the PPDU including a signal field, a Very High Throughput-Signal-A (VHT-SIG-A) field, a Very High Throughput-Signal-B (VHT-SIG-B) field and a padded data block, generating a first data block by removing zero or more physical padding bits from the padded data block in a physical layer; and generating a second data block by removing zero or more Medium Access Control (MAC) padding bits from the first data block in a MAC layer.

1. A method for transmitting data blocks in a wireless communication system, the method performed by a transmitter and comprising:
generating a data block in a Medium Access Control (MAC) layer; generating a first padded data block by appending zero or more MAC padding bits to the data block; delivering the first padded data block from the MAC layer to a physical (PHY) layer; generating a second padded data block by appending zero or more PHY padding bits to the first padded data block in the PHY layer; and transmitting a PHY protocol data unit (PPDU) to a receiver over an operating channel, the PPDU including a first signal field, a second signal field and the second padded data block, wherein the first signal field includes information required to interpret the PPDU, wherein the second signal field includes information indicating a modulation and coding scheme for the data block, and wherein a size for the second signal field increases as a bandwidth of the operating channel increases.
