Abstract: Systems and methods for frame addressing in DL MU-MIMO transmissions are described. In some embodiments, identifier information identifying receiving devices for a frame may be included in a header of that frame. In various embodiments, the identifier information may include a concatenation of respective identifiers for each of the plurality of receiving devices. In some other embodiments, the identifiers may include information identifying a pre-defined device group including several receiving devices. In some embodiments, the frame may include a medium access control (MAC) frame transmitted by an access point/personal basic service set control point (PCP/AP), and the recipient devices may include non-AP/non-PCP stations (STAs). In some such embodiments, a receiving STA address (RA) field or transmitting STA address (TA) field in a MAC header of the MAC frame may be used as a container for the recipient identifier information.

Abstract: Techniques to enable dynamic bandwidth management at the physical layer level while maintaining backwards compatibility in wireless systems is provided. Furthermore, techniques for reducing the occurrence of exposed nodes are provided. A transmitter may transmit a frame including an indication that a PHY layer sub-header defining a bandwidth associated with a channel is present. Furthermore, the transmitter may transmit a third frame after receiving a second frame from a receiver to indicate to legacy stations that the TXOP was successful.
