US 2023/0141728 A1 · APPARATUS AND METHODS FOR TB PPDU ALIGNMENT FOR MULTI-LINK TRIGGERED UPLINK ACCESS IN A WIRELESS NETWORK

Abstract

Embodiments of the present invention prevent interference caused by the simultaneous transmission and reception of data in a constrained multi-link operation of a wireless network. According to one embodiment, a frame from a first affiliated AP of a multi-band wireless AP is transmitted for receipt by an STA, and a second affiliated wireless AP of the multi-band wireless AP is scheduled to transmit a trigger frame to the wireless STA over a second wireless link. Accordingly, the trigger frame is transmitted from the second affiliated wireless AP to the wireless STA over the second wireless link, and the response frame solicited by the frame is scheduled for transmission after the predetermined value has expired following an end of the PPDUs containing the trigger frame.

Claims20

Dependent claims

A method of data transmission in a wireless network, the method comprising:

transmitting a frame from a first affiliated wireless access point (AP) of a multi-band wireless AP for receipt by a wireless station (STA), wherein the transmitting performed over a first wireless link, and the frame solicits a response frame;
determining that a second affiliated wireless AP of the multi-band wireless AP is scheduled to transmit a trigger frame to the wireless STA over a second wireless link, the trigger frame comprising a carrier sense (CS) required field having a predetermined value;
and
transmitting the trigger frame from the second affiliated wireless AP for receipt by the wireless STA over the second wireless link, wherein the response frame solicited by the frame is scheduled for transmission after the predetermined value has expired following an end of a physical layer conformance procedure (PLCP) protocol data units (PPDUs) which contains the trigger frame.

A wireless communication device comprising:

a first transceiver and a second transceiver configured to send and receive data over the wireless network;
and
a processor operable to:
cause the first transceiver to transmit a frame from a first affiliated wireless access point (AP) of a multi-band wireless AP for receipt by a wireless station (STA), wherein the transmitting performed over a first wireless link, and the frame solicits a response frame;
determine that a second affiliated wireless AP of the multi-band wireless AP is scheduled to transmit a trigger frame to the wireless STA over a second wireless link, the trigger frame comprising a carrier sense (CS) required field having a predetermined value;
and
cause the second transceiver the trigger frame from the second affiliated wireless AP for receipt by the wireless STA over the second wireless link, wherein the response frame solicited by the frame is scheduled for transmission after the predetermined value has expired following an end of a physical layer conformance procedure (PLCP) protocol data units (PPDUs) which contains the trigger frame.
