Abstract: Systems, methods, and apparatus are disclosed for increasing reuse in wireless communications. In one aspect, a method of wireless communication is provided, transmitting a message to a first station indicating an identified transmission opportunity for the first station to communicate with a second station. The method further comprises transmitting a first wireless communication signal to at least a third station utilizing beamformed wireless communication such that the first wireless communication signal to the third station has a received signal level below a threshold at one or both of the first and second stations. The identified transmission opportunity is based on whether a transmission of a second wireless communication signal between the first and the second stations occurs over a period of time that is at least partially concurrent with the utilized beamformed communication.

Abstract: A method includes receiving a data fragment of a block of data fragments of a single data unit from a wireless device at a receiver. The method includes, in response to determining that the data fragment is a last data fragment of the block of data fragments, transmitting an acknowledgement to the wireless device. The acknowledgement indicates whether each data fragment of the block of data fragments was received from the wireless device. The method includes, in response to determining that the data fragment is a last data fragment of the single data unit, transmitting the acknowledgment to the wireless device. The method further includes, in response to determining that the data fragment is not the last data fragment of the block of data fragments or the last data fragment of the single data unit, refraining from transmitting the acknowledgement to the wireless device.
