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

Claim 8:
9. A system comprising:
an access point (AP) configured to:
detect one or more parameters of a channel of communication between the AP and a wireless station (STA), wherein when detecting the one or more parameters of the channel of the communication, the AP is configured to detect a length of one or more packets transmitted between the AP and the STA in one or more prior DL transmissions;
determine a training configuration for 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 length of the one or more packets being less than a packet length threshold value, when determining the training configuration, the AP is configured to perform at least one of:
determine to reduce the length of training symbols to be included in the training block of the DL transmission compared to a length of training symbols included in a training block of the one or more prior DL transmissions; or
determine to reduce the number of the training symbols to be included in the training block of the DL transmission compared to a number of the training symbols included in the training block of the one or more prior DL transmissions; and

transmit the DL transmission to the STA over the channel, the DL transmission including the training block and a data portion, the training block configured according to the training configuration,
wherein the STA is configured to determine the channel estimation of the channel of the communication using the training block of the DL transmission received at the STA.
