Data transmission method and apparatus thereof

An apparatus for data transmission, comprising:

• a transceiver, configured to perform wireless transmission and reception to and from a second apparatus;
• a processor, coupled to the transceiver, and configured to:
• detect a medium condition to obtain a detection result;
• receive, via the transceiver, a second channel information from the second apparatus;
• obtain a punctured sub-channel information corresponding to a transmission bandwidth based on the detection result and the second channel information;
• transmit, via the transceiver, a data frame through non-punctured sub-channels of the transmission bandwidth to the second apparatus based on the punctured sub-channel information;
• and
• receive, via the transceiver, an acknowledgement frame from the second apparatus in response to the second apparatus receiving the data frame.

A data transmission method, comprising:

• detecting, by a processor of a network node, whether there are any radar signals in a transmission bandwidth for a data transmission;
• in response to a radar signal in at least one sub-channel of the transmission bandwidth, puncturing, by the processor, the at least one sub-channel;
• and
• transmitting, by the processor, a first beacon frame to a user equipment (UE) to indicate the at least one punctured sub-channel in the transmission bandwidth.
