Syntax

cfgTRS = getTRSConfiguration(cfgHETB)

Description

example

cfgTRS= getTRSConfiguration(cfgHETB)generatescfgTRS, a valid PHY configuration for the IEEE®802.11™ high-efficiency trigger-based (HE TB) packet format. The function sets properties ofcfgTRS通过更改输入PHY配置的属性子集cfgHETB. You can parameterize an HE TB uplink PPDU transmitted in response to a frame containing a triggered response scheduling (TRS) Control subfield by using thecfgTRSoutput. For a detailed description of the HE WLAN formats, see[1].

Open Live Script

Configure and generate a WLAN HE TB waveform to be transmitted in response to a frame containing a TRS Control subfield.

Create an HE TB configuration object, specifying the triggering frame type.

cfgHETB = wlanHETBConfig('TriggerMethod','TRS');

Generate a valid configuration by using thegetTRSConfigurationobject function, displaying the result.

cfgTRS = getTRSConfiguration(cfgHETB)
cfgTRS = wlanHETBConfig with properties: FeedbackNDP: 0 TriggerMethod: 'TRS' ChannelBandwidth: 'CBW20' RUSize: 242 RUIndex: 1 PreHEPowerScalingFactor: 1 NumTransmitAntennas: 1 NumSpaceTimeStreams: 1 StartingSpaceTimeStream: 1 SpatialMapping: 'Direct' STBC: 0 MCS: 0 DCM:0频道编码：“ bcc” prefecpaddingFactor：4 numDatasymbols：10默认过程：0 GuardInterval：3.2000 HeltfType：4 numHeltfSymbols：1 SingleSteramPilots：1 BSSCOLOT：1 BSSCOLOR：1 BSSCOLOR：1 BSSCOLOR：0 SPATIALREUSE1：0 SpatialReuse1：15 Spatialreuse2：15 Spatialig oferique2：15 Hessre：15 spatialreuse3：15 spatialreuse 3：[9x1 double] Postfecpaddingsource：'MT19937AR与种子'Postfecpaddinged：73

Get the PSDU length in bytes and generate a PSDU for transmission.

psduLength = getPSDULength(cfgTRS); psdu = randi([0 1],8*psduLength,1);

Generate and plot the waveform.

waveform = wlanWaveformGenerator(psdu,cfgTRS); figure; plot(abs(waveform)); title('HE TB Waveform'); xlabel('Time (nanoseconds)'); ylabel('Amplitude');

PPDU

The physical layer (PHY) protocol data unit (PPDU) is the complete physical layer convergence procedure (PLCP) frame, including PLCP headers, MAC headers, the MAC data field, and the MAC and PLCP trailers.
