Wireless communications

A method for wireless communication, comprising:

• transmitting, using a transmit path, an acknowledgement preamble for a received data packet as soon as reception of the received data packet is complete, the received data packet being received using a receive path separate from the transmit path;
• determining, in parallel with transmitting the acknowledgement preamble, whether the received data packet comprises an error;
• and
• terminating transmission of the acknowledgement if the received data packet comprises an error.

One or more computer-readable storage memory devices, comprising code configured to direct a processing unit to:

• perform a transmission of a first preamble during a clear channel assessment of a wireless network, wherein a first node in the wireless network transmits the first preamble;
• detect, in parallel with the transmission of the first preamble, a plurality of transmissions of corresponding plurality of preambles, wherein a corresponding plurality of nodes in the wireless network transmit the preambles;
• determine a later start between the transmission of the first preamble and each of the plurality of transmissions of the corresponding plurality of preambles;
• and
• terminate the transmission of the first preamble if the determining indicates that the transmission of the first preamble started after the transmission of the second preamble.
