US 12,010,683 B2 · Transmission of a second ACK after failure of first ACK

Abstract

In a wireless local area network (LAN) system, a first station (STA) may check the transfer failure of a first acknowledgement (ACK) signal for a first frame, the signal being received through a first link. The first STA may transmit report information related to the transfer failure of the first ACK signal to a second STA through a second link. Here, the report information may include identification information associated with the first link. The first STA may receive a second frame from the second STA through the first link. The first STA may transmit a second ACK signal for the second frame to the second STA through the first link on a narrowband.

Dependent claims

A method in a Wireless Local Area Network (LAN) system, the method comprising:

confirming, by a first station (STA), a delivery failure of a first acknowledgment (ACK) signal for a first frame received through a first link;
transmitting, by the first STA to a second STA, report information related to the delivery failure of the first ACK signal through a second link, wherein the report information includes identification information related to the first link;
receiving, by the first STA, a second frame from the second STA through the first link;
and
transmitting, by the first STA to the second STA, a second ACK signal for the second frame in a narrowband through the first link,
wherein the report information includes narrowband resource unit (RU) allocation request information.
