    摘要: Logic of an access point may transmit a null data packet for beamforming training and transmit a beamforming report poll to the first station on a user list before receiving a transmission from the first station on the user list. Logic may wait for a timeout period to determine whether the first station on the user list will respond to the null data packet prior to transmitting the beamforming report poll. Logic may receive from the first station an indication that the first station is a slow beamforming report responder. Logic may reorder the user list to position a fast beamforming responder as the first station. And logic of the station may determine that the station is unable to complete and transmit the report so the logic may wait to transmit the beamforming report in response to a subsequent beamforming report poll frame.

    摘要: Aspects of the present disclosure provide techniques for sounding procedures using frames with some portions that use relatively long symbol durations. Certain aspects of the present disclosure provide a method that may be performed by an access point. The method generally includes generating one or more frames, collectively having one or more training fields allowing one or more stations to calculate channel information and an indication of one or more feedback parameters for the one or more stations to use for generating the channel information; transmitting the one or more frames; and receiving channel information from at least one of the stations calculated, in accordance with the one or more feedback parameters, for a corresponding one or more reporting units based on the one or more training fields, wherein the channel information is received via a report containing a plurality of channel information parameters for each of the one or more reporting units.

    摘要: A method, apparatus, and computer program for carrying out channel sounding are provided. Said method comprises: causing, by an apparatus, transmission of a request for space-time channel sounding to at least one unassociated access node; receiving, in the apparatus as a multi-antenna transmission and in response to said request, at least one message comprising space-time sounding information from at least one unassociated access node; determining, by the apparatus, at least one parameter describing space-time channel quality from the received space-time sounding information; and causing, by the apparatus, transmission of the at least one determined parameter to an associated access node or causing selection of an unassociated access node for further communication based at least partly on the determined at least one parameter.

    摘要: A method and apparatus are disclosed for updating a beam set of a UE (User Equipment) in a cell of a wireless communication system, wherein a base station applies beam-forming for transmission and/or reception in the cell and there are at least two beams in the cell. In one embodiment, the method includes the base station determines the beam set of the UE. The method also includes the base station monitors an uplink transmission from the UE via the beam set. The method further includes the base station sends a signaling to the UE for triggering at least an aperiodic reference signal transmission if no DM RS associated with the uplink transmission is detected via at least one beam in the beam set. In addition, the method includes the base station updates the beam set according to at least a beam or beams via which the aperiodic reference signal is received from the UE.
