摘要： Embodiments of an access point (AP), station (STA), and method of communication are generally described herein. The AP may perform channel sensing in a first channel of a first frequency band and a second channel of a second frequency band to obtain access for transmission of a physical layer convergence procedure (PLCP) protocol data unit (PPDU) that comprises multiple subframes. The transmission of the PPDU may be configurable to use a multi-band layer-1 aggregation of the first and second channels. While the second channel is unavailable, the AP may transmit one or more subframes on the first channel without usage of the multi-band layer-1 aggregation. When it is determined that the second channel has become available, the AP may switch to synchronized transmission of the subframes on the first and second channels in accordance with the multi-band layer-1 aggregation.

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： Embodiments of an AP and wake up radio (WUR) non-AP station (STA) are generally described herein. The AP may transmit a WUR packet to wake up a wireless local area network (WLAN) radio of the WUR non-AP STA. A non-WUR portion of the WUR packet may include legacy fields and a BPSK mark to spoof high throughput (HT) devices receiving the WUR packet. The AP may transmit the BPSK mark in a channel that includes a lower guard band, a transmission bandwidth, and an upper guard band. The AP may encode the BPSK mark in accordance with: on-off keying (OOK) modulation in a center portion of the transmission bandwidth; and orthogonal frequency division multiplexing (OFDM) in a remaining portion of the transmission bandwidth that excludes the center portion.

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.
