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 of 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, the PPDU including a Very High Throughput-Signal-A (VHT-SIG-A) field, a Very High Throughput-Signal-B (VHT-SIG-B) field and the second padded data block over an operating channel, wherein the VHT-SIG-A field includes group information indicating the receiver to receive the PPDU, wherein the VHT-SIG-B field includes information indicating a length of the data block before padding, and wherein a number of bits for the VHT-SIG-B field is determined based on a bandwidth of the operating channel.
