    摘要: Apparatuses, methods, and computer readable media for channel bonding and bonded channel access. The apparatus comprising processing circuitry configured to: gain access to a first 10 MHz channel and to a second 10 MHz channel, and encode a physical layer (PHY) protocol data unit (PPDU) for transmission over a bonded channel, the bonded channel comprising the first 10 MHz channel and the second 10 MHz channel, where the PPDU is encoded to comprise a legacy preamble portion to be transmitted on the first 10 MHz channel and a repeated legacy preamble portion to be transmitted on the second 10 MHz channel, the PPDU further including a non-legacy portion, the non-legacy portion comprising a non-legacy signal field indicating a modulation and coding scheme (MCS) used to encode a data portion of the non-legacy portion, the data portion to be transmitted on the bonded channel.

    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) in accordance with an enhanced PHY layer protocol. The PPDU may be encoded for transmission in a dedicated short-range communication (DSRC) frequency band. The NGV STA may encode the PPDU to include a preamble, one or more data portions, and one or more midambles. The one or more midambles may occur within the PPDU after the preamble and after at least one of the data portions. The NGV STA may encode a preamble that includes an NGV SIG-A field that indicates: whether the PPDU includes the one or more midambles, and a periodicity of the one or more midambles.

    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 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.
