摘要： The present application provides a method for determining a CP. A STA performs channel estimation, determines a CP value according to the result of channel estimation, and sends indication information to an AP, wherein the indication information is used for indicating the CP value, so that the AP may choose a suitable CP according to the indication information. Therefore, overhead may be reduced and system throughput may be optimized.

摘要： This application relates to the field of communications technologies, in particularly related to wireless fidelity (WIFI) technologies, and provides a method and apparatus for reducing peak to average power ratio (PAPR) for transmitting a physical layer protocol data units (PPDUs). The method can be used for both an access point (AP) and a station (STA). The method comprises: operating on a first disregard bits sequence to obtain a second disregard bits sequence, wherein the first disregard bits sequence is with all bits set to ‘1’, and transmitting the PPDU, wherein the PPDU comprises the second disregard bits sequence.

摘要： A wireless access point, AP, (110a) is disclosed, which is configured to share a transmission opportunity with at least one further wireless access point (110b) within a Multi-AP set using a Coordinated Beamforming, C-BF, scheme. The wireless AP (110a) comprises a processing circuitry (111) configured to generate a C-BF Null Data PPDU Announcement, C-BF NDPA, frame, wherein the C-BF NDPA frame comprises a Multi-AP set identifier. Moreover, the wireless AP (110a) comprises a communication interface (113) configured to transmit the C-BF NDPA frame to one or more wireless stations (120a) associated with the wireless AP (110a) and/or to one or more further wireless stations (120b) associated with the at least one further wireless AP (110b) within the Multi-AP set.

摘要： 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.

摘要： 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.
