This disclosure provides a method for channel state feedback in a non-simultaneous transmit and receive (NSTR) operation mode and the communication device thereof. The method implemented in a first communication device, the first communication device being configured with a plurality of links for communicating with a second communication device, the method including: receiving first data over a channel of a first link of the plurality of links; determining whether a channel of a second link of the plurality of links is idle in a case that no data is received over the channel of the second link and the first link and the second link belong to a non-simultaneous transmit and receive (NSTR) link pair; and transmitting a feedback frame over the channel of the first link, wherein the feedback frame includes a first field indicating whether the channel of the second link is idle.

Method for channel state feedback in a non-simultaneous transmit and receive (NSTR) operation mode

This disclosure provides a backoff counting method in a non-simultaneous transmit and receive (NSTR) operation mode and the communication device for the method. The method includes: configuring a plurality of backoff counters for counting backoff slots with no medium activity of channels of the plurality of links; synchronizing a count value of a first backoff counter of the plurality of backoff counters with a count value of a second backoff counter of the plurality of backoff counters, if the first backoff counter starts counting later than the second backoff counter or resumes counting after a pause, wherein the count value of the second backoff counter is smaller than that of the first backoff counter; and transmitting or receiving a signal on a channel of at least one of the plurality of links after all the backoff counters reach a predefined value.
