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.

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： Embodiments of a station (STA) and method of communication are generally described herein. The STA may be included in a first plurality of STAs affiliated with a first multi-link logical entity (MLLE). A plurality of links may be established between the first MLLE and a second MLLE, wherein the second MLLE may be affiliated with a second plurality of STAs. The STA may receive a first subset of a sequence of MAC protocol data units (MPDUs). A second subset of the sequence of MPDUs may be transmitted by another STA of the first plurality of STAs. The STA may transmit a block acknowledgement (BA) frame that includes: a number of BA bitmaps, configurable to values greater than or equal to one; and BA control information for each of the BA bitmaps.

摘要： Systems and techniques for locating a radio transmission source by scene reconstruction are described herein. A multipath radio signal—comprised of two or more multipath components—may be received at an antenna array. A collection of angle-of-arrival (AoA) values may be created from the multipath components. Thus, each AoA in the collection corresponds to one of the multipath components. An optical image of the environment may be obtained and possible reflective surfaces for the multipath components identified in the optical image. A set of paths may be created in a model of the environment by backtracking from the antenna array along the AoAs in the collection of AoA values. Here, the backtracking simulates reflections of the ray off of the surfaces identified in the optical image. A transmitter of the multipath radio signal may then be located via the set of paths.

摘要： A station (STA), when operating as a responding STA (RSTA) for time-synchronization of a plurality of initiating STAs (ISTAs) in a time-synchronized network (TSN), may determine, during a negotiation phase, whether each of the ISTAs that intend to participate in one or more measurement phases are requesting to be polled or are requesting not to be polled. For the ISTAs that are requesting to be polled, the RSTA may perform a polling phase prior to performing each of the one or more measurement phases. For the ISTAs that are requesting not to be polled, the RSTA may refrain from performing a polling phase prior to performing each of the one or more measurement phases. The RSTA can directly trigger the measurement phase for ISTAs that are requesting not to be polled. By grouping ISTAs into polling and non-polling groups, efficiency improvements are achieved.

摘要： An apparatus of a station (STA) includes memory and processing circuitry coupled to the memory. The processing circuitry is to detect a first peer-to-peer (p2p) wireless communication link of the STA is active within a wireless TSN network. A wireless link information element corresponding to the first p2p wireless communication link is encoded for transmission to an AP. The wireless link information element includes at least one attribute of the first p2p wireless communication link. A gate control list (GCL) received from the AP is decoded. The GCL originates from a central network controller (CNC) of the wireless TSN network, and the GCL is based on the at least one attribute in the wireless link information element. Transmission and reception schedules of the first p2p wireless communication link are configured based on the GCL.

摘要： An apparatus of a station (STA) includes memory and processing circuitry coupled to the memory. The processing circuitry is to decode an MSDU received at a MAC layer of the STA, the MSDU including a data packet and descriptor metadata. A DSCP tag and launch time information are detected in the descriptor metadata. The launch time information indicates a desired transmission time of the data packet. The data packet is placed in a first transmission queue of a plurality of transmission queues of the MAC layer based on the DSCP tag. A scheduled transmission time of at least a second transmission queue of the plurality of transmission queues is determined to conflict with the desired transmission time. The scheduled transmission time is adjusted based on the launch time information. The data packet is encoded for transmission by the desired transmission time using a wireless communication channel.

摘要： An access point (AP) station (STA) configured for communicating with another STA within a synchronized transmission opportunity (S-TXOP) may encode an S-TXOP trigger for transmission at a beginning of the S-TXOP. The S-TXOP trigger may be followed by a plurality of slots within the S-TXOP. The S-TXOP trigger may include a synchronization information field, a station information list field and an optional schedule information field. The STA information list field may include an AID of each STA that is scheduled to communicate during the slots and an indication of whether semi-static configuration is enabled. When the S-TXOP trigger includes the optional schedule information field, it may include resource information for each slot which may include a slot identifier and a slot type indicator. The resource allocation for each slot further includes a scheduling information element when the semi-static configuration for the corresponding slot is not enabled.
