Assignee: MAXLINEAR, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A method comprising:
detecting, by an access point (AP), one or more parameters of a channel of communication between the AP and a wireless station (STA), wherein detecting the one or more parameters of the channel of the communication comprises:
detecting an airtime of the communication; and
determining a distance between the AP and the STA based on the airtime of the communication;

determining, by the AP, a training configuration for a channel estimation of the channel of the communication based on the one or more parameters of the channel of the communication, the training configuration indicating at least one of a number of training symbols or a length of training symbols to include in a training block of a downlink (DL) transmission, wherein responsive to the distance between the AP and the STA being greater than a distance threshold value, determining the training configuration comprises determining to increase the number of training symbols to be included in the training block of the UL transmission compared to a number of training symbols included in a training block of one or more prior UL transmissions;
transmitting a trigger frame from the AP to the STA, the trigger frame including the training configuration and instructions for the STA to include the training block configured according to the training configuration in an uplink (UL) transmission to the AP;
receiving, at the AP, the UL transmission from the STA; and
determining the channel estimation of the channel of the communication using the training block of the UL transmission received at the AP.
