摘要： This disclosure describes systems, methods, and devices for using a per-bandwidth virtual sensing network allocation vector (NAV) for sub-band operations. An access point may send an overlapping basic service set (OBSS) frame using at least a subset of an operating bandwidth of the access point, wherein the OBSS frame signals to a receiving device operating in the at least the subset of the operating bandwidth to set a network allocation vector (NAV) of the receiving device to on only in the at least the subset of the operating bandwidth; send an initial control frame (ICF) using the operating bandwidth; identify an initial control response (ICR) received, based on the ICF and based on the OBSS frame having used the at least the subset of the operating bandwidth; send an in-basic service set (in-BSS) transmission; and identify an acknowledgement to the in-BSS transmission.

摘要： Embodiments disclosed herein provide favored channel access for STAs whose transmissions have failed or collided. After a first collision or transmission failure, a STA receives prioritized access in order to re-transmit a PPDU. If an initial transmission of the PPDU is unsuccessful (e.g., the initial transmission fails or if the PPDU collides with another transmission), for retransmission of the PPDU, the STA may update the EDCA parameters to EDCA parameters for prioritized access, may determine a backoff for accessing the wireless medium, and may retransmit the PPDU based on the EDCA parameters for prioritized access (i.e., using the updated EDCA parameters). The EDCA parameters for prioritized access may be configured to give the STA a higher probability of accessing the wireless medium for a PPDU retransmission than use of the initial EDCA parameters.

摘要： Methods, apparatuses, and computer readable media for trigger frames or transmission opportunities with multiple start times and delayed uplink start are disclosed. Apparatuses of a station (STA) are disclosed, where the apparatuses comprise processing circuitry configured to decode a trigger frame, the trigger frame indicating a time allocation of a plurality of time allocations and indicating a resource unit (RU) for an uplink transmission for the STA. The processing circuitry is further configured to: encode an uplink (UL) trigger-based (TB) physical (PHY) protocol data unit (PPDU) in accordance with the time allocation and the RU and configure the STA to transmit the UL TB PPDU on the RU during the time allocation. Trigger frames are disclosed that include indications of multiple time allocations for multiple RUs where the STAs are permitted to use delayed transmissions or random access within the time allocations.

摘要： This disclosure describes systems, methods, and devices related to in-channel and adjacent channel interference avoidance. The device may perform a clear channel assessment (CCA) measurement on a portion of a second operating channel, wherein the portion shares a contiguous edge with a first operating channel that is adjacent to the second operating channel. The device may detect an energy on the portion of the second operating channel based on the CCA measurement. The device may compare the detected energy to an energy detection (ED) threshold. The device may determine to communicate on the second operating channel based on the comparison of the energy to the ED threshold.

摘要： This disclosure describes systems, methods, and devices related to an enhanced hybrid automatic repeat request (HARQ). A device may determine two or more HARQ medium access control (MAC) frames. The device may determine a difference between a first number of bits of a physical layer (PHY) codeword and a second number of bits of a first HARQ MAC frame of the two or more HARQ MAC frames. The device may generate, based on the difference, a third number of bits, wherein the first number of bits is equal to a sum of the second number of bits and the third number of bits. The device may generate an aggregated MAC frame comprising the first HARQ MAC frame, the third number of bits, and a second HARQ MAC frame of the two or more HARQ MAC frames. The device may send the aggregated MAC frame.

摘要： Embodiments of a Next Generation Vehicle-to-Everything (NGV) station (STA) and method of communication are generally described herein. The NGV STA may encode a physical layer convergence procedure (PLCP) protocol data unit (PPDU) for transmission in a dedicated short-range communication (DSRC) frequency band allocated for vehicular communication by NGV STAs and legacy STAs. In some cases, the NGV STA may encode the PPDU in accordance with an NGV enhanced physical (PHY) layer protocol, and includes usage of a mid-amble, space-time block coding (STBC), or low-density parity check (LDPC) coding. In other cases, the NGV STA may encode the PPDU in accordance with a legacy PHY layer protocol that is compatible with the legacy STAs, and excludes usage of the mid-amble, the STBC, and the LDCP coding.

摘要： An access point station (AP) configured for operation in a wireless local area network (WLAN) may establish a target wake-up time (TWT) agreement with a non-access point station (STA). The TWT agreement may comprise an unavailability period during which the STA is unavailable. During establishment of the TWT agreement, a priority threshold may be indicated by the STA. The AP may encode frames for transmission to the STA during a transmission opportunity (TXOP) established by the AP. The TXOP may begin prior to activation of the TWT agreement. The AP may continue to send the frames during the unavailability period of the TWT agreement when the unavailability period occurs during the TXOP and when a priority of the frames meets the priority threshold. When the priority of the frames does not meet the priority threshold, the AP may end the TXOP before the unavailability period and may refrain from sending frames to the STA during the unavailability period.

摘要： Methods, apparatuses, and computer readable media for initial control and response frames, where an apparatus of an access point (AP) comprises processing circuitry configured to: encode, for transmission to a station (STA), an initial control frame comprising a transmission opportunity (TxOP) duration and information regarding the TxOP, and decode, from the STA, an initial control response frame, the initial control response frame comprising an availability of the STA during the TxOP. The STA may determine not to participate in the TxOP to operate on another radio. The AP may modify the parameters of the TxOP based on the initial control response frame received from the STA.

摘要： Methods, apparatuses, and computer readable media include an apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to decode a legacy preamble of a physical layer (PHY) protocol data unit (PPDU), determine whether the legacy preamble comprises an indication that the PPDU is an extremely-high throughput (EHT) PPDU, and in response to the determination indicating the PPDU is the EHT PPDU, decode the EHT PPDU. Some embodiments determine a spatial stream resource allocation based on a row of a spatial configuration table, a row of a frequency resource unit table, a number of stations, and location of the station relative to the number of stations in user fields of an EHT-signal (SIG) field. To accommodate 16 spatial streams, some embodiments extend the length of the packet extension field, extend signaling of a number of spatial streams, and/or extend a number of EHT-SIG symbols.
