Abstract: Embodiments of a high-efficiency WLAN (HEW) master station and method for communicating in a Wireless Network are generally described herein. In some embodiments, the HEW master station comprises a receiver configured to receive an uplink multi-user multiple-input multiple-output (MU-MIMO) transmission from a plurality of scheduled HEW stations. The uplink MU-MIMO transmission may comprise at least an HEW short-training field (STF) (HEW-STF) transmitted by each of the scheduled HEW stations. The HEW-STFs received from the HEW stations are distinguishable. The master station may process the HEW-STFs received from the scheduled HEW stations to set receiver gain for reception of UL-MIMO data from the scheduled HEW stations. In some embodiments, a single automatic gain control (AGC) setting may be determined from the combined HEW-STF resulting in improved receiver performance in UL MU-MIMO.

Abstract: Embodiments of a system and method for distributed channel access for device-to-device (D2D) communication in a wireless network are generally described herein. User equipment (UE) may transmit a connection identifier (CID) code at a beginning of a contention window to request channel access for a D2D transmission to a receiving device. Links for D2D transmissions from a transmitting device to a receiving device are identified by a CID that is mapped to a CID code. The UE may receive a bandwidth grant from the receiving device during the contention window, along with bandwidth grants for other CIDs, in an order based on a priority level of the CID. The UE may transmit data after reception of the bandwidth grants in time-frequency resources indicated in an associated one of the bandwidth grants. In some embodiments, spatial-reuse and variable resource size allocation are supported.

Abstract: Methods, apparatus, and computer-readable media are described for notching a 6 GHz channel. A station associates with an access point on a 6 GHz band. A notching pattern indication is decoded from data received from the AP after associating with the AP. A notching region within a channel within the 6 GHz band is determined based on the notching pattern indication. The notching pattern indicates a width of a notching region and a location of the notching region within the channel. The notching region covers bandwidth occupied by an incumbent system within the channel. A physical layer convergence procedure (PLCP) protocol data unit (PPDU) is encoded for transmission on the channel to the AP. The PPDU is encoded to exclude transmission within the notching region.
