Abstract
This disclosure provides methods, devices and systems for wireless communications over a 320 MHz bandwidth. Some implementations more specifically relate to signaling techniques for indicating the bandwidth of a physical layer convergence protocol (PLCP) protocol data unit (PPDU) transmitted in a secondary 160 MHz channel of the 320 MHz bandwidth. In some implementations, an access point (AP) may transmit an aggregated PPDU (A-PPDU) that includes a first sub-PPDU transmitted within a primary 160 MHz channel and a second sub-PPDU transmitted within a secondary 160 MHz channel. In such implementations, the first sub-PPDU may carry bandwidth information indicating the bandwidth of the first sub-PPDU within the primary 160 MHz channel and the second sub-PPDU may carry bandwidth information indicating the 320 MHz bandwidth.
