摘要： Apparatuses, methods, and computer readable media for restriction of upload traffic in a high-efficiency wireless local-area network are disclosed. A high-efficiency (HE) wireless local area network (HEW) device including circuitry is disclosed. The circuitry may be configured to generate a HE packet comprising a first indication of whether a random access is allowed, and generate the HE packet with a second indication of a type of packet allowed in the random access, if random access is allowed. A HE station including circuitry is disclosed. The circuitry may be configured to receive a HE packet from a access point, the packet comprising an indication of whether random access is permitted during a transmission opportunity, and determine based on the HE packet whether the random access is allowed, and if the random access period is not allowed, then return to a power saving mode without decoding the rest of the HE packet.
