Selective retransmission procedure

A method for wireless communication by a first wireless device, comprising:

• transmitting a packet to a second wireless device, the packet including one or more information units, at least one identifier of the information units, and at least one wireless device identifier;
• receiving a first trigger frame from the second wireless device, the first trigger frame identifying at least one information unit of the one or more information units to be retransmitted;
• and
• transmitting, to the second wireless device, the at least one information unit identified by the first trigger frame to be retransmitted.

A wireless communication device at a first wireless device comprising:

• at least one processor;
• and
• at least one memory communicatively coupled with the at least one processor and storing processor-readable code that, when executed by the at least one processor, causes the wireless communication device to:
• receive a packet from at least one second wireless device, the packet including one or more information units, at least one identifier of the one or more information units, and at least one wireless device identifier;
• determine, based on the at least one wireless device identifier and the at least one identifier of the one or more information units, at least one information unit of the one or more information units to be retransmitted by the at least one second wireless device;
• and
• transmit a first trigger frame to the at least one second wireless device, the first trigger frame identifying the at least one information unit to be retransmitted.
