US 12,588,059 B2 · Data in communication system supporting multiple links

Abstract

Disclosed are a method and device for transmitting and receiving data in a communication system supporting multiple links. The method of a first device comprises the steps of: performing a first backoff operation for a first AC in a first link; performing a second backoff operation for a second AC in the first link; performing a third backoff operation for a third AC in a second link; if the first backoff operation and the second backoff operation in the first link are performed successfully, selecting one AC from among the first AC and the second AC; and, if the third backoff operation is performed successfully, simultaneously performing a first transmission operation of a first frame comprising a data unit corresponding to the selected one AC in the first link and a second transmission operation of a second frame comprising a data unit corresponding to the third AC in the second link.

A method of a first device, comprising:

performing a first backoff operation for a first access category (AC) on a first link;
performing a second backoff operation for a second AC on the first link;
performing a third backoff operation for a third AC on a second link;
in response to that the first backoff operation and the second backoff operation succeed on the first link, selecting one AC from among the first AC and the second AC;
and
in response to that the third backoff operation succeeds, simultaneously performing a first transmission operation of a first frame including a data unit corresponding to the selected one AC on the first link and a second transmission operation of a second frame including a data unit corresponding to the third AC on the second link.
