Abstract
Proposed herein is a method and device for setting limited RUs and MRUs in a WLAN system. More specifically, a receiving STA receives a PPDU from a transmitting STA through a preset frequency band, and decodes the PPDU. The receiving STA is an STA operating only in a 20MHz band. The PPDU includes a preamble and a data field. The data field is received through resources other than the first RU and the first MRU among the preset frequency band.

A method in a wireless local area network (WLAN) system, the method comprising:
- receiving, by a receiving station (STA), a Physical Protocol Data Unit (PPDU) from a transmitting STA through a preset frequency band;
- and
- decoding, by the receiving STA, the PPDU,
- wherein the receiving STA is an STA that operates only in a 20 MHz band,
- wherein the PPDU includes a preamble and a data field,
- wherein the data field is received through resources other than a first resource unit (RU) and a first multiple RUs (MRU) among the preset frequency band,
- wherein, when the preset frequency band is a 40 MHz band,
- when the 40 MHz band consists of only 26 tone RUs, the 40 MHz band includes first to 18th 26 tone RUs, when the 40 MHz band consists of only 52 tone RUs, the 40 MHz band includes first to 8th 52 tone RUs, when the 40 MHz band consists of only 106 tone RUs, the 40 MHz band includes first to 4th 106 tone RUs, and when the 40 MHz band consists only of 242 tone RUs, the 40 MHz band includes first and second 242 tone RUs,
- wherein the first RU includes the 5th and 14th 26 tone RUs and the first and second 242 tone RUs, and
- wherein the first MRU includes an MRU in which the 5th 26 tone RU and the second 52 tone RU are aggregated, an MRU in which the 14th 26 tone RU and the 6th 52 tone RU are aggregated, an MRU in which the 5th 26 tone RU and the first 106 tone RU are aggregated, an MRU in which the 5th 26 tone RU and the second 106 tone RU are aggregated, an MRU in which the 14th 26 tone RU and the 3rd 106 tone RU are aggregated, and an MRU in which the 14th 26 tone RU and the 4th 106 tone RU are aggregated.
A receiving station (STA) in a wireless local area network (WLAN) system, the receiving STA comprising:
- a memory;
- a transceiver;
- and
- a processor being operatively connected to the memory and the transceiver,
- wherein the processor is configured to:
- receive a Physical Protocol Data Unit (PPDU) from a transmitting STA through a preset frequency band, and
- decode the PPDU,
- wherein the receiving STA is an STA that operates only in a 20 MHz band,
- wherein the PPDU includes a preamble and a data field,
- wherein the data field is received through resources other than a first resource unit (RU) and a first multiple RUs (MRU) among the preset frequency band,
- wherein, when the preset frequency band is a 40 MHz band,
- when the 40 MHz band consists of only 26 tone RUs, the 40 MHz band includes first to 18th 26 tone RUs, when the 40 MHz band consists of only 52 tone RUs, the 40 MHz band includes first to 8th 52 tone RUs, when the 40 MHz band consists of only 106 tone RUs, the 40 MHz band includes first to 4th 106 tone RUs, and when the 40 MHz band consists only of 242 tone RUs, the 40 MHz band includes first and second 242 tone RUs,
- wherein the first RU includes the 5th and 14th 26 tone RUs and the first and second 242 tone RUs, and
- wherein the first MRU includes an MRU in which the 5th 26 tone RU and the second 52 tone RU are aggregated, an MRU in which the 14th 26 tone RU and the 6th 52 tone RU are aggregated, an MRU in which the 5th 26 tone RU and the first 106 tone RU are aggregated, an MRU in which the 5th 26 tone RU and the second 106 tone RU are aggregated, an MRU in which the 14th 26 tone RU and the 3rd 106 tone RU are aggregated, and an MRU in which the 14th 26 tone RU and the 4th 106 tone RU are aggregated.
A method in a wireless local area network (WLAN) system, the method comprising:
