摘要：
This disclosure describes systems, methods, and devices related to spatial reuse using quasi-omni and directional clear channel assessment (CCA). A device may use multiple antenna elements in an antenna array to perform both a quasi-omni CCA and a directional CCA during the same time slot. Some embodiments may use different antenna weight vectors to switch the antenna array between quasi-omni and directional CCA. Other embodiments may dedicate some elements of the array to quasi-omni CCA and other elements of the array to directional CCA. The device may use the combination of quasi-omni CCA and directional CCA to determine whether a channel is free for transmitting.
