Abstract
Examples are disclosed for simultaneous transmitting and receiving packets in a wireless local access network (WLAN). In some examples, a source node in the WLAN may transmit a packet to a destination node in the WLAN and may receive an implicit acknowledgement (ACK) packet from the destination node. The source node may stop transmitting a remaining portion of the packet if the implicit ACK packet is not received within a defined time interval or if a dummy/packet payload for the implicit ACK packet is not successfully decoded. Also, the destination node may or may not include a data payload in an implicit ACK packet sent responsive to receiving the packet from the source node. Other examples are described and claimed.
Claims18
An apparatus for a source node in a wireless local area network (WLAN) comprising:
- circuitry;
- a transmit component for execution by the circuitry to transmit a packet having a first header and a first data payload to a destination node in the WLAN;
- a receive component for execution by the circuitry, the receive component to wait for receipt of an implicit acknowledgement (ACK) packet having a second header from the destination node, the implicit ACK packet to indicate receipt of at least the first header by the destination node;
- and
- a stop component for execution by the circuitry to cause the transmit component to stop transmission of any remaining portion of the first data payload awaiting transmission when the stop component has determined that the second header for the implicit ACK packet has not been received within a defined time interval.
A method implemented at a source node in a wireless local area network (WLAN) comprising:
- transmitting, at the source node, a packet having a first header and a first data payload to a destination node in the WLAN;
- continuing to transmit the first data payload to the destination node based on whether at least a second header for an implicit acknowledgement (ACK) packet has been received from the destination node to indicate receipt of at least the first header by the destination node;
- and
- stopping transmission of a remaining portion of the first data payload awaiting transmission when the second header for the implicit ACK packet has not been received within a defined time interval.
