Syntax

mode = compressionMode(cfg)

Description

mode = compressionMode(cfg) returns the compression mode of the ultra high-reliability or extremely high-throughput (UHR or EHT) configuration object cfg, as defined in Table 38-24 of IEEE® P802.11bn™ [1] and Table 36-29 of IEEE Std 802.11be™-2024 [2].

Open Live Script

Create a configuration object for an EHT TB transmission, setting the channel bandwidth to 320 MHz and specifying that the configuration has an MRU of size 3*996.

cfgEHTTB = wlanEHTTBConfig(ChannelBandwidth="CBW320",RUSize=[996 996 996],RUIndex=[1 2 3]);

Use the compressionMode object function to return the compression mode of the configuration.

compressionMode(cfgEHTTB)

0

Input Arguments

Format configuration, specified as an object of type wlanUHRTBConfig, wlanUHRELRConfig, or wlanEHTTBConfig.

Output Arguments

collapse all

Compression mode, returned as 0 or 3. The U-SIG field of any UHR or EHT packet has a compression mode subfield that consists of two bits. In the UHR trigger-based (UHR TB) and EHT TB cases, the value of this subfield is 0. In the UHR enhanced long range (UHR ELR) case, the value of this subfield is 3.

Data Types: double
