Abstract
The present specification suggests a method for transmitting and receiving a signal, by a station, in a wireless LAN (WLAN) system supporting a maximum of eight space time streams, and an apparatus therefor. More specifically, the present specification suggests a method for transmitting and receiving a signal including a pilot sequence for 2 channel bonding per each space time stream when a station transmits and receives a signal through a channel in which two channels are bonded, and an apparatus therefor.
Claims8
A method in a wireless LAN (WLAN) system, the method comprising:
- generating, by a first station (STA) supporting a plurality of space time streams (STSs), a first pilot sequence having a length of 36 for two 2.16 GHz channels based on a second pilot sequence having a length of 12,
- wherein the second pilot sequence is repeated three times in the first pilot sequence,
- wherein the first pilot sequence is generated for an enhanced directional multi-gigabit physical protocol data unit (EDMG PPDU),
- wherein the second pilot sequence is set to one sequence among a plurality of candidate pilot sequences based on an index of an STS to be used for the EDMG PPDU,
- wherein each of the plurality of candidate pilot sequences has a length of 12,
- wherein the plurality of candidate pilot sequences are configured for the plurality of STSs, respectively,
- wherein the plurality of the candidate pilot sequences are mutually orthogonal, and
- wherein a maximum number of the plurality of STSs is eight;
- and
- transmitting, by the first STA to a second STA, the EDMG PPDU including the first pilot sequence through the two 2.16 GHz channels.
A first station (STA) supporting a plurality of space time streams (STSs) in a wireless LAN (WLAN) system, the station comprising:
- a transceiver having at least one radio frequency (RF) chain and configured to transmit a radio signal;
- and
- a processor connected to the transceiver unit,
- wherein the processor is configured to:
- generate a first pilot sequence having a length of 36 for two 2.16 GHz channels based on a second pilot sequence having a length of 12,
- wherein the second pilot sequence is repeated three times in the first pilot sequence,
- wherein the first pilot sequence is generated for an enhanced directional multi-gigabit physical protocol data unit (EDMG PPDU),
- wherein the second pilot sequence is set to one sequence among a plurality of candidate pilot sequences based on an index of an STS to be used for the EDMG PPDU,
- wherein each of the plurality of candidate pilot sequences has a length of 12,
- wherein the plurality of candidate pilot sequences are configured for the plurality of STSs, respectively,
- wherein the plurality of the candidate pilot sequences are mutually orthogonal, and
- wherein a maximum number of the plurality of STSs is eight;
- and
- transmit, via the transceiver, the EDMG PPDU including the first pilot sequence through the two 2.16 GHz channels.
