摘要： Communications between an access point, AP, of an AP multi-link device, MLD, and a non-AP station, STA, of a STA MLD are established on one or more links of a plurality of links (1410). The non-AP STA receives a frame transmitted by the AP on a first link of the plurality of links (1420). The non-AP STA then either transmits a response to the AP on the first link responsive to receiving the frame from the AP (1430) or performs a listening operation on the plurality of links (1440).

摘要： An access point, AP, and a station, STA, communicate with each other, with the AP indicating to the STA either or both of a preamble detection, PD, channel and a signaling, SIG, content channel and with the STA being initially monitoring a primary frequency segment of a plurality of frequency segments in an operating bandwidth of the AP (1510). A downlink, DL, or triggered uplink, UL, communication is performed between the AP and the STA during a transmission opportunity, TXOP, such that: (i) during the TXOP, the STA monitors a preamble on the PD channel and decodes a SIG content on the SIG content channel (1520); and (ii) after an end of the TXOP, the STA switches to the primary frequency segment.

摘要： Communications between an access point, AP, and a non-AP station, STA, are established in a plurality of frequency segments within a basic service set, BSS, bandwidth (1410) or on at least a first link and a second link. An extreme-high-throughput, EHT, subchannel selective transmission, SST, operation is performed between the AP and the non-AP STA in the plurality of frequency segments (1420) or on the first link and the second link. A trigger-enabled target wake time, TWT, session period, SP, for the EHT SST operation by either indicating one of the plurality of frequency segments as containing a resource unit, RU, allocation addressed to the non-AP STA (1422) or indicating one of the first link and the second link on which an operating frequency segment is located during the TWT SP.

摘要： A first station, STA, in a non-access point, non-AP, multi-link device, MLD, which has a constraint on simultaneous transmission and reception, TX/RX, on the first link and the second link, receives a Physical Layer Convergence Protocol, PLCP, Protocol Data Unit, PPDU, on a first link or a second link (310). In response to the PPDU meeting a condition, one or more other STAs of a plurality of STAs in the non-AP MLD are refrained from performing an operation (320).

摘要： Embodiments of the present invention a computer-implemented process for automatically synchronizing TXOPs for a multi-link device (200), MLD, to improve wireless network performance and prevent IDC is depicted according to embodiments of the present invention. The process can be performed by a multi-link device (200) performing a multi-link operation, and the multi-link device (200) can act as a wireless access point or a wireless station. The MLD (200) includes a first wireless station (210), STA, associated with a fist wireless link and a second wireless STA (215) associated with a second wireless link. The MLD (200) can include more wireless STAs (225) for communicating over different wireless links.

摘要： Embodiments of the present invention provide a punctured preamble enabling wireless devices to efficiently use a channel (e.g., an 80 or 160 MHz channel) where a primary service is operating. A Wideband Channel Access Mechanism for 20 MHz/80 MHz operating STAs is provided so that a 20 MHz/80 MHz operating STA can dynamically move to a secondary channel to improve wireless performance of the STA. An AP coordinates the operating channel switch of the 20 MHz/80 MHz operating STA. An EHT cooperative multi-band operation can be applied to the preamble punctured PPDU for simultaneous multi-band operation.

摘要： Embodiments of the present invention provide a method and apparatus for hybrid ARQ acknowledgement and retransmission requests for decoding failed MPDUs of an A-MPDU received by an STA. The source address and receiver address of a failed MPDU can be verified according to a MAC header CRC that can be included in an A-Control frame, for example (1705). For verifying the source address and the receiver address in MAC header, according to some embodiments, the MAC header CRC is jointly calculated over the first two octets of the MPDU delimiter of an A-MPDU subframe.
Moreover, a Hybrid ARQ frame is defined to include Block Ack Bitmap subfield representing the received status of a plurality of MPDUs according to starting sequence control number, for example.-

摘要： Mechanisms of CCA status reporting and NAV distribution for coordinated transmissions in a multi-AP WLAN. A coordinator AP (101) may broadcast a RTS frame to a set of coordinated APs (102, 103), which allow the coordinated APs (102, 103) with a CCA clear status to set a protected period in a CST frame to silence the associated non-AP STAs (104, 105). The coordinator AP (101) also polls the coordinated APs (102, 103) to have them individually report their CCA statuses as well as additional information used for transmission coordination. In some embodiments, a status report from a coordinated AP (102, 103) may integrate the protected period setting and the CCA clean status indication, and therefore the coordinator AP (101) just needs to poll for such a report without using RTS/CTS exchange. A coordinated AP (102, 103) may set a protected period to end at the complete transmission of a coordination frame. The coordination frame may specify the remaining TXOP duration information.

摘要： An encryption mechanism used on cooperative multi-band wireless STA architecture that enables full duplex operations. In encrypting a frame, an AAD can be constructed by using a selected MAC address, which may not be associated with a band to be used for transmitting the frame in an upcoming TXOP. An STA that supports simultaneous transmission in a multi-band operation uses the same MAC address to encrypt the frames to be transmitted on different bands. An AAD is constructed by using a same MAC address corresponding to one of the transceivers. A transmit STA may specify band information used for encryption in the MAC header, which serves to signal the receive STA to decrypt the frame by using the proper information.
