An electronic device receives a physical layer (PHY) protocol data unit (PPDU) including a PHY preamble including a non-high-throughput (Non-HT) short training field (L-STF), a Non-HT long training field (L-LTF), a Non-HT signal (L-SIG) field, a repeated Non-HT signal (RL-SIG) field, and a universal signal (U-SIG) field. The electronic device checks a control field in the PPDU. The control field indicates whether the PHY preamble in the PPDU carries payload information and the PPDU carries no data field carrying payload information. The electronic device obtains the payload information from the PHY preamble and processes the payload information if the control field indicates that the PHY preamble in the PPDU includes the payload information and the PPDU carries no data field.

Low latency in wireless communication system

An access point (AP) multi-link device (MLD) is associated with a non-AP MLD. The non-AP MLD comprises a first station (STA) and a second STA. The AP MLD comprises a first AP affiliated with the AP MLD and associated with the first STA and a second AP affiliated with the AP MLD and associated with the second STA. The first AP sets up a first link with the first STA and the second AP sets up a second link with the second STA. The first link uses a millimeter wave band and the second link uses a frequency band below the millimeter wave band. The first AP transmits a beamforming training signal for the first link to the first STA and receives beamforming feedback information from the first STA when the second link is enabled.
