    摘要: Wireless devices, methods and computer readable media for spatial reuse in a high efficiency wireless local-area network. An apparatus of a HEW station may comprise circuitry. The circuitry may be configured to determine if a plurality of links with a plurality of wireless stations are device-to-device links that indicate that there is a spatial reuse opportunity; and transmit a packet that comprises a spatial reuse indication that there is the spatial reuse opportunity, if the spatial reuse opportunity is indicated. The spatial reuse opportunity may be an uplink orthogonal frequency division multiple access (OFDMA) with the plurality of wireless stations, a downlink OFDMA with the plurality of wireless stations, or a downlink multiple users multiple-input multiple-output (MU-MIMO). The spatial reuse indication may include a margin that indicates how a second HEW station may adjust a transmit power and clear channel assessment to use within the spatial opportunity.

    摘要: Apparatus, computer readable medium, and method for generating and receiving signal fields in a high efficiency wireless local-area network (WLAN) are disclosed. A high-efficiency wireless local-area network (HEW) device including circuitry is disclosed. The circuitry may be configured to: receive a physical (PHY) header or media access control (MAC) header from a second HEW station, wherein the PHY header or MAC header comprises an indication of a spatial reuse opportunity and a defer duration; adjust one or more parameters to determine whether or not the wireless medium is in use; and determine whether to transmit within the spatial reuse opportunity based on the adjusted one or more parameters. The circuitry may be configured to adjust one or more parameters to determine whether or not the wireless medium is in use in where the parameters are signal detect (SD) threshold, a mid-packet detection (MPD) threshold, and an energy detection (ED) threshold.

    摘要: Wireless device, method, and computer readable media for channel contention in wireless communication devices. The wireless communication device may include hardware processing circuitry configured to: determine to adapt the channel contention, and configured to adapt the channel contention settings by changing a level of a clear channel assessment (CCA) and adapting at least one additional channel contention setting. The hardware processing circuitry may be configured to adapt the channel contention settings by raising a level of the clear channel assessment (CCA) and by decreasing a power used to transmit, raising a back-off time, or modifying a portion of or parameter to a distributed coordination function (DCF). The hardware processing circuitry may be configured to adapt the channel contention settings by decreasing the clear channel assessment (CCA) and increasing a power used to transmit or decreasing an amount of time to wait after a CCA determines the channel is free.

    摘要: A transmitter/receiver pair may estimate a first channel interference caused during the spatial reuse phase by the transmitter/receiver pair to other transmitter/receiver pairs over a channel. A second channel interference experienced by the transmitter/receiver pair may be estimated during the spatial reuse phase by the transmitter/receiver pair from the other transmitter/receiver pairs. An interference margin may be estimated for the channel based on the first and second channel interferences. The interference margin may be announced to the other transmitter/receiver pairs in frame. The interference margin may then be complied with while communicating over the channel in order to control the interference.
