摘要： This disclosure describes systems, methods, and devices related to extended range modulation and coding scheme (MCS). A device may generate a first orthogonal frequency-division multiplexing (OFDM) signal to be transmitted in a frequency band. The device may generate a second OFDM signal to be transmitted in the frequency band, wherein the second OFDM signal is a duplicate of the first signal. The device may assign a reduced number of guard intervals (GIs) to the first OFDM signal and the second OFDM signal. The device may cause to send the first OFDM signal and the second OFDM signal using the frequency band.

摘要： This disclosure describes systems, methods, and devices related to enhanced aggregate preemption. A device may divide a transmit opportunity (TXOP) transmission into physical layer convergence procedure service data unit (PSDU) or physical layer (PHY) convergence protocol data unit (PPDU) transmissions. The device may establish fixed time intervals between two continuous PSDU or PPDU transmissions. The device may sense an idle status of a channel after an end of each PSDU or PPDU transmission. The device may send a first suspend request (SR) control frame after an end of receiving a current PSDU or PPDU transmission.

摘要： This disclosure describes systems, methods, and devices related to low latency preemption. A device may establish time gaps between consecutive physical layer (PHY) convergence protocol data units (PPDUs) to facilitate preemption opportunity for low latency (LL) transmission. The device may detect a suspend/resource request (SR) transmitted over predefined null tones, wherein the SR is received from a station device (STA). The device may determine if a current transmit opportunity (TXOP) is preemptable and communicate this status through a control frame. The device may set a suspend request (SR) feedback report support subfield within an ultra high reliability (UHR) capabilities element based on a capability to support the SR feedback report.

摘要： This disclosure describes systems, methods, and devices related to scrambler initialization for multi-user (MU) clear to send (CTS) transmission. A first device may identify a MU request to send (RTS) frame received from a second device. The first device may determine an initial state of a scrambler based on the first 7 bits of a service field of the MU-RTS frame. The first device may cause first data to be scrambled, using the initial state of the scrambler, resulting in second data. The first device may cause to send a MU-CTS frame that comprises the second data to the second device.

摘要： Techniques for resource block allocation in a multi-user MIMO High Efficiency WLAN system are provided. Specifically, teachings that when taken alone or together, provide a device or a group of devices with an improved resource allocation for the reduction of usable tone waste, are presented. The present disclosure includes a system that provides a user with a technique allocating data tones prior to the encapsulation unit or overhead tones on a resource block unit. Further, the total allocated bandwidth can be reduced prior resource allocation to overcome modulation and coding scheme downgrading caused by severe puncturing. Alternatively, only band edge basic resource blocks are reduced to account for overhead tones which largely reside on band edges.

摘要： Disclosed herein are systems and methods that are directed to non-contiguous channel bonding in wireless networks. Non-contiguous channels can refer to channels that are not adjacent to one another in the frequency domain. In one aspect, the non-contiguous channel bonding may support non-high efficiency (HE) physical layer convergence procedure protocol data unit (PPDU) communications. For example, non-high throughput (non-HT) devices, for example, legacy devices, can be supported using non-high throughput (non-HT) format frames. In one embodiment, this can include integration of non-contiguous channel bonding with multi-user (MU) request to send, clear to send (RTS/CTS) exchanges. In another embodiment, a trigger-initiated uplink (UL) PPDU can be supported with non-contiguous channel bonding.
