摘要： An antenna device includes a plurality of dipole antennas and a port. Each of the dipole antennas is connected to the port. The dipole antennas are arranged around the port. Each of the dipole antennas comprises two ends. The device further includes a plurality of passive elements. The ends of the dipole antennas and the passive elements are interchangeably arranged around the port such that each of the passive elements is situated between ends of two different antennas from the plurality of dipole antennas. One or more switches are configured to switch between an omnidirectional state, in which the ends of the dipole antennas are not connected to the plurality of passive elements, and a directional state, in which at least one end of one of the passive elements is connected to at least one end of one of the antennas.

摘要： The disclosure relates to an access point device (AP) for communicating with a client device (STA). The AP may include a transceiver configured to transmit a first data packet indicating a set of groups, wherein each group of the set of groups is associated with a specific set of transmission parameters. The transceiver of the AP may also be configured to transmit a second data packet indicating an allocation for at least part of the groups. Furthermore, the transceiver of the AP may also be configured to receive a response frame using at least part of random access (RA) resources selected by the STA for the at least part of the groups.

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.

摘要： A radio station, in particular an access point, for client localization in a multipath indoor environment is disclosed. The radio station comprises: a circular antenna array comprising uniform circularly arranged antenna elements; and a processor configured to: transform first input data from the circular antenna array into second input data using a transform that transforms the first steering vector of the circular antenna array into a second steering vector of a virtual linear antenna array; and transform the second input data into third input data by using a transform that transforms the second steering vector of the virtual linear antenna array into a third steering vector of a second virtual linear antenna array, comprising a larger number of antenna elements than the virtual linear antenna array; and determine an angle of arrival based on the third input data.
