摘要： Methods, apparatuses, and computer readable media for channelization of vehicle-to-everything (V2X) networks in a wireless network are disclosed. An apparatus of an of a next generation vehicle to everything (V2X) (NGV) wireless device includes processing circuitry configured to: encode a management frame, the management frame including an indication of resource units (RUs) for use by NGV stations during transmission opportunities (TXOPs) where the RUs part of a channel. The processing circuitry is further configured to configure the NGV wireless device to transmit the management frame on the channel and configure the NGV wireless device to transmit a short sequence frame (SF) at a start of each TXOP of the TXOPs. An apparatus for V2X networks is disclosed that is configured to transmit a packet in center tones of a channel and to simultaneously transmit parity or redundancy information for the packet on tones on either side of the center tones.

摘要： This disclosure describes systems, methods, and devices related to time-sensitive networking in wireless communications. A device may exchange time-sensitive networking (TSN) capabilities with one or more station devices associated with the device. The device may identify a TSN capability request received from a TSN management entity associated with a TSN domain. The device may transmit a TSN capability response to the TSN management entity. The device may identify a TSN capability configuration frame from the TSN management entity. The device may configure the TSN capabilities based on the TSN capability configuration frame.

摘要： An access point (AP) may be configured by processing circuitry to operate as a coordinator AP for performing BSS channel level coordination. The coordinator AP is configured to assign non-overlapping channels to one or more coordinated APs of overlapping BSSs to schedule time-sensitive traffic to help ensure bounded latency, jitter and reliability per BSS. In some embodiments, the AP may be configured for performing transmission level coordination and may initiate a coordinated transmission opportunity (TXOP) for resource assignment to control contention access among managed BSSs. To perform the BSS channel level coordination, the coordinator AP is configured to encode a multi-AP trigger frame (M-TF) to initiate the coordinated TXOP. The M-TF may be encoded to include a time-sensitive operation IE indicating how each STA is to access the channel within the coordinated TXOP.
