Abstract

A multi-link device using a plurality of links is disclosed. The multi-link device comprises: a transceiving unit; and a processor. When the multi-link device transmits a plurality of PPDUs simultaneously on the plurality of links using the transceiving unit, the processor determines a transmission end time of the plurality of PPDUs on the basis of whether the multi-link device transmits a frame requesting an ACK.

First claim

1 - 20 . (canceled)

21 . A non-access point (AP) multi-link device that uses a plurality of links including a first link and a second link, wherein a reception in the second link by the non-AP multi-link device is restricted due to an internal leakage from the first link when the non-AP multi-link device performs a transmission in the first link, the non-AP multi-link device comprising:
a transceiver; and a processor, wherein the processor is configured: to respectively access each of a channel in the first link and a channel in the second link using a channel access method, wherein the channel access method uses a backoff counter, wherein an initial value of the backoff counter is set to an obtained random number, the backoff counter is decreased by one when a channel accessed in the channel access method is idle during a slot time, and when a value of the backoff counter is 0, a station of the non-AP multi-link device is allowed to perform a transmission; and even when a backoff counter of a channel access in the first link reaches 0, not to perform transmission in the first link.

22 . The non-AP multi-link device of claim 21 , wherein when not performing transmission in the first link, the processor is configured to maintain a value of the backoff counter of the channel access in the first link.

23 . A method of operating a non-access point (AP) multi-link device that uses a plurality of links including a first link and a second link, wherein a reception in the second link by the non-AP multi-link device is restricted due to an internal leakage from the first link when the non-AP multi-link device performs a transmission in the first link, the method comprising:
respectively accessing each of a channel in the first link and a channel in the second link using a channel access method, wherein the channel access method uses a backoff counter, wherein an initial value of the backoff counter is set to an obtained random number, the backoff counter is decreased by one when a channel accessed in the channel access method is idle during a slot time, and when a value of the backoff counter is 0, a station of the non-AP multi-link device is allowed to perform a transmission; and even when a backoff counter of a channel access in the first link reaches 0, not performing transmission in the first link.

24 . The method of claim 23 , wherein the not performing transmission in the first link comprises maintaining a value of the backoff counter of the channel access in the first link.
