Abstract:
Methods, computer readable media, and apparatuses are disclosed for spatial reuse. A high efficiency station (HE STA) that includes circuitry is disclosed. The circuitry may be configured to: determine if a link with a wireless device is a D2D link with a spatial reuse opportunity; and transmit a packet that includes an indication that there is the spatial reuse opportunity for the duration of the packet, if the link with the wireless device is the D2D link with the spatial reuse opportunity. The circuitry may be configured to: receive a packet from a second HE STA, where the packet includes an indication that there is a spatial opportunity for the duration of the packet; adjust at least one of the following group: a transmit power and a clear channel assessment parameter; and transmit a second packet to a wireless device in the spatial opportunity in accordance with D2D communication.
