Physical (PHY) layer control for wireless local area network (WLAN) communication

A method for wireless communication by an apparatus of a first station (STA), comprising:

• receiving, via at least part of a wireless channel, a first physical layer convergence protocol (PLCP) protocol data unit (PPDU) from an access point (AP), the first PPDU including physical (PHY) layer control signaling indicating an assigned subchannel of the wireless channel and identifying the first STA;
• and
• adjusting a PHY layer receiver configuration of the first STA based on the PHY layer control signaling to tune to the assigned subchannel as an operating channel for subsequent communications between the AP and the first STA, the subsequent communications including a second PPDU having a format associated with a bandwidth of the assigned subchannel.

An apparatus of a first access point (AP), comprising:

• at least one modem configured to output, for transmission via a wireless channel, a first physical layer convergence protocol (PLCP) protocol data unit (PPDU) that includes physical (PHY) layer control signaling indicating an assigned subchannel of the wireless channel and identifying at least one station (STA), wherein the PHY layer control signaling instructs the at least one STA to tune to the assigned subchannel as an operating channel for subsequent communications between the first AP and the at least one STA;
• and
• the at least one modem configured to output, for transmission via the assigned subchannel, a second PPDU using a format associated with a bandwidth of the assigned subchannel.

A method for wireless communication by an apparatus of a first access point (AP), comprising:

• transmitting, via a wireless channel, a first physical layer convergence protocol (PLCP) protocol data unit (PPDU) that includes a universal signal field (U-SIG) followed by a signaling field that includes physical (PHY) layer control signaling that identifies a first station (STA) and an assigned subchannel of the wireless channel, wherein the PHY layer control signaling instructs the first STA to adjust a receiver bandwidth configuration of the first STA to tune the assigned subchannel for subsequent communications between the first AP and the first STA.
