Abstract: A system and method for triggering beamformed uplink (UL) physical layer protocol data units (PPDUs) are disclosed. The system comprises an access point (AP) and one or more stations (STAs). The AP sends a soliciting frame to the one or more STAs, wherein the frame comprises a null data packet, NDP, request, NDPR, indicator and receive an NDP PPDU from each of the one or more solicited STAs. The AP, then computes the precoder for each of the one or more solicited STAs and send the one or more solicited STA a trigger frame with a beamforming report. The AP receives from each of the STAs one or more beamformed UL data packets and sends a block acknowledgement to the one or more solicited STAs indicating the successful receipt of the one or more beamformed UL data packets.

Abstract: A device on a wireless network generates duration data for determining a duration of a time interval. A transmission is then instructed, by the device, to transmit the duration data and a downlink payload including an aggregated Media Access Control (MAC) layer data unit, the downlink payload being transmitted on first subcarriers. The transmission also includes a trigger that configures the at least one other device on the network to transmit an uplink payload within the time interval, and during at least part of the transmission of the downlink payload, on second subcarriers that are at different frequencies to the first subcarriers.

Abstract: An apparatus for deriving a submatrix {tilde over (G)}−1 is described. The apparatus for deriving a submatrix {tilde over (G)}−1 is configured to select an N-elements-column and an N-elements-row of an N×N-Matrix G or G−1. The apparatus for deriving a submatrix {tilde over (G)}−1 is configured to rearrange the selected column to the rightest column and the selected row to the lowest row of G or G−1 so as to generate a N×N-matrix Gp or Gp−1. The apparatus for deriving a submatrix {tilde over (G)}−1 is configured to calculate a submatrix {tilde over (G)}−1 by G ~ - 1 = A - AbcA d - 1 + c T Ab , wherein the parameters (N−1)×(N−1)-submatrix A, b, d, c are obtained from the Gp or the Gp−1; wherein G p = [ G ~ b c T d ] , G p - 1 = [ A b ~ c ~ T d ~ ] .

Abstract: Disclosed are a physical layer (PHY) protocol data unit (PPDU) transmission method and a related apparatus. The method includes: generating a PPDU, where the PPDU includes a universal signal field (U-SIG), and the U-SIG includes a subfield indicating that the PPDU is a null data packet (NDP); and sending the PPDU. In this way, a beamformee (Bfee) that receives the NDP can identify the NDP earlier. This helps improve efficiency of reading the NDP by the Bfee. The PPDU is an NDP used for a standard after 802.11ax. In a scenario in which wireless communication is performed by using the standard (for example, 802.11be) after 802.11ax, the Bfee can perform channel estimation based on the NDP.

Abstract: The present disclosure suggests to expand and improve the method of utilizing channel resources in the 802.11be standard by allowing the use of multiple and non-contiguous portions of a channel. Supporting multiple resource units (MRUs) and non-contiguous resource units (RUs) improves the channel utilization by making it more efficient due to enhancing the capability of leveraging the channel selectivity. To this end, a wireless network device for resource allocation is provided and configured to define a non-contiguous MRU in the bandwidth of the channel. The channel comprises a plurality of RUs, and the MRU is defined based on non-punctured RUs after puncturing one or more of the RUs of the channel, and/or is defined by aggregating two or more non-adjacent RUs of the channel.
