    Abstract: An apparatus for wireless communication includes data defragmentation logic configured to receive, during a first transmit opportunity, a first data packet from a first device and a second data packet from a second device. The first data packet includes a first data fragment, and the second data packet includes a second data fragment. The apparatus also includes block acknowledgement generation logic configured to generate a block acknowledgement frame including a first block acknowledgement bitmap and a second block acknowledgement bitmap. The first block acknowledgement bitmap indicates at least the first data fragment received from the first device, and the second block acknowledgement bitmap indicates at least the second data fragment received from the second device. The apparatus further includes a wireless interface configured to transmit the block acknowledgement frame to the first device and to the second device.

    Abstract: Techniques for reducing delay in scheduling traffic transmission in an overlapping basic service set (OBSS) environment by modifying backoff mechanisms are disclosed. In some examples, a device (e.g., station (STA), access point (AP)) decodes at least a portion of a preamble of a packet to determine whether the packet is sent by a member of an OBSS (e.g., STA, AP from a different BSS). Backoff operations are typically deferred as a result of the decoding. Aspects of the present disclosure provide a method, apparatus, and system in which the backoff operations are resumed prior to expiration of the period reserved for an OBSS packet by the network allocation vector (NAV). That is, the device may not honor the NAV of the OBSS packet, and instead perform spatial reuse by transmitting another packet (or signal) on the same frequency channel during the NAV of the OBSS packet.
