摘要： In response to a first communication device determining that a specific wireless local area network (WLAN) communication link has been negotiated with a second communication device for traffic corresponding to a first traffic identifier (TID), the first communication device transmits packets corresponding to the first TID to the second communication device only via the specific WLAN communication link. In response to the first communication device determining that no WLAN communication link has been negotiated with the second communication device for traffic corresponding to a second TID, transmitting, by the first communication device, packets corresponding to the second TID to the second communication device via multiple WLAN communication links.

摘要： A communication device determines that simultaneous transmission/reception via multiple frequency segments in a WLAN is not permitted, and transmits a first packet in a first frequency segment and a second packet in a second frequency segment. The communication device determines that an end of the first packet does not align with an end of the second packet and that the first packet and/or the second packet prompts transmission of a respective response packet a defined time period after transmission of the corresponding one of the first packet and the second packet. In response to having determined that simultaneous transmission/reception is not permitted and that the first packet and/or the second packet prompts transmission of the respective response packet, the communication device pads the first packet and/or the second packet so that an end of transmission of the first packet is aligned with an end of transmission of the second packet.

摘要： A communication device selects a frequency bandwidth via which a physical layer (PHY) protocol data unit (PPDU) will be transmitted in a vehicular communication network, and generates, the PPDU i) according to a downclocking ratio of 1/2, and ii) based on an orthogonal frequency division multiplexing (OFDM) numerology defined by an IEEE 802.11ac Standard. In response to the selected frequency bandwidth being 10 MHz, the PPDU is generated according to the downclocking ratio of 1/2 and based on the OFDM numerology defined by the IEEE 802.11ac Standard for 20 MHz PPDUs. In response to the selected frequency bandwidth being 20 MHz, the PPDU is generated according to the downclocking ratio of 1/2 and based on the OFDM numerology defined by the IEEE 802.11ac Standard for 40 MHz PPDUs.

摘要： Systems and methods are provided for introducing time diversity in a transmitter. The systems and methods may include receiving, at the transmitter, a request from a receiver to retransmit data. The systems and methods may further include receiving an input of data corresponding to the data requested for retransmission at a first transmitter block. The systems and methods may further include operating on the signals using the first transmitter block in at least one of a first mode and a second mode, such that an output of signals from the first transmitter block is dependent on a time-varying function and corresponds to the data requested by the receiver for retransmission.

摘要： An access point manages a first wireless local area network (WLAN) in a 6 GHz radio frequency (RF) band and ii) a second WLAN operating in another RF band. The access point generates a physical layer (PHY) data unit to include a management frame having i) first information indicating first network parameters of the first WLAN, and ii) second information indicating second network parameters of the second WLAN. The AP transmits the PHY data unit in the other RF band to provide, to any client stations that are operating in the other RF band and that are also capable of operating in the 6 GHz band: the first information indicating the first network parameters of the first WLAN operating in the 6 GHz RF band to assist the any client stations that are operating in the other RF band with joining the first WLAN operating in the 6 GHz RF band.

摘要： A first communication device determines whether a specific wireless local area network (WLAN) communication link, among a plurality of WLAN communication links corresponding to respective frequency segments, has been negotiated with a second communication device for a first traffic stream. In response to determining that the specific WLAN communication link has been negotiated for the first traffic stream, the first communication device transmits packets in the first traffic stream only via the specific WLAN communication link. In response to determining that no WLAN communication link has been negotiated with the second communication device for the first traffic stream, the first communication device transmits packets in the first traffic stream via multiple WLAN communication links corresponding to different frequency segments.

摘要： A communication device generates a first packet for transmission in a first frequency segment, and generates a first physical layer (PHY) preamble of the first packet to include a first field that indicates a first overall bandwidth that the first packet spans. The communication device generates a second packet for transmission in a second frequency segment, and generates a second PHY preamble of the second packet to include a second field that indicates a second overall bandwidth that the second packet spans. The communication device transmits the first packet in the first frequency segment beginning at a first time, and simultaneously transmits the second packet in the second frequency segment beginning at a second time that is different than the first time.

摘要： A communication device operates according to a communication protocol defines a first set of frequency resource units (RUs) and a second set of frequency RUs. The first set of frequency RUs includes at least a first subset of frequency RUs having a first bandwidth and a second set of RUs having a second bandwidth greater than the first bandwidth, and the second set of frequency RUs omits at least some of the frequency RUs in the first subset of frequency RUs. The communication device determines that a communication channel to be used for an uplink (UL) multi-user (MU) transmission spans a frequency bandwidth greater than 160 MHz, and allocates one or more frequency RUs for the UL MU transmission, including: in response to determining that the communication channel spans the frequency bandwidth greater than 160 MHz, selecting one or more frequency RUs from a second set of frequency RUs.

摘要： A method, performed by a first communication device, for transmitting a wireless local area network (WLAN) packet to a WLAN network interface device of a second communication device is described. The second communication device includes a separate wakeup radio (WUR) coupled to the WLAN network interface device. The WLAN packet is generated at the first communication device to include a WUR identifier associated with a neighbor communication device. The WUR identifier is usable by the WUR of the second communication device to identify WUR packets transmitted by the neighbor communication device. The neighbor communication device is different from the first communication device. The WLAN packet is transmitted by the first communication device to the WLAN network interface device of the second communication device.

摘要： A communication device determines whether a PHY data unit is to be transmitted in a first frequency band from among multiple frequency bands in which a WLAN communication protocol permits operation. The multiple frequency bands also include a second frequency band. The communication device determines whether the PHY data unit is to include a PS-Poll frame, and whether a BSS color is currently disabled for the WLAN. In response to i) determining that the PHY data unit is to be transmitted in the first frequency band, ii) determining that the PHY data unit is not to include a PS-Poll frame, and iii) determining that the BSS color is not currently disabled for the WLAN: the communication device determines that a TXOP duration subfield in a PHY preamble of the PHY data unit cannot be set to a value defined by the WLAN communication protocol for indicating a TXOP duration that is unspecified.
