1. An apparatus for wireless communication, comprising:
- a processing system configured to;
receive a message instructing each of multiple devices to transmit a packet at least partially concurrently with each transmission of the other multiple devices, the message comprising an indication of a time period associated with transmission of an acknowledgment regarding reception of the packet, the acknowledgment being a block acknowledgment; and
generate the packet comprising an indicator having a value greater than a time associated with a transmission of the packet, the value being based on the indication of the time period; and
an interface configured to provide the packet for transmission during the time associated with the transmission of the packet,wherein the message instructing each of the multiple devices to transmit the packet comprises a packet transmission time instruction, and wherein a duration indicated by the packet transmission time instruction is greater than the time associated with the transmission of the packet by at least the time period associated with transmission of the block acknowledgment and a time period associated with an extended interframe space (EIFS).
