1. A method for transmitting data to a plurality of Stations (STAs) through a transmission channel by an Access Point (AP) in a Wireless Local Area Network (WLAN) system, wherein the transmission channel is divided into a plurality of resource units which are allocated to the plurality of STAs respectively, the method comprising:
interleaving a plurality of data units for the plurality of STAs based on sizes of the plurality of resource units allocated to the plurality of STAs to generate a plurality of interleaved data units; and transmitting, through the transmission channel, a Physical layer Protocol Data Unit (PPDU) frame including the plurality of interleaved data units respectively on the plurality of resource units to the plurality of STAs, wherein a set of sizes available to a resource unit allocated to a first STA among the plurality of STAs includes a first size and a second size, wherein the interleaving of the plurality of data units for the plurality of STAs comprises:
when the size of the resource unit allocated to the first STA is the first size, interleaving a data unit for the first STA using a first set of interleaving parameter values; andwhen the size of the resource unit allocated to the first STA is the second size, interleaving the data unit for the first STA using a second set of interleaving parameter values, and wherein the first size is smaller than a size of the transmission channel, the second size is smaller than the first size, and the second set of interleaving parameter values is different from the first set of interleaving parameter value. |
