Abstract: This disclosure describes systems, and methods related to parallel transmission of high efficiency SIGNAL field in communication networks. A device may generate a high efficiency preamble in accordance with a high efficiency communication standard, the high efficiency preamble including, at least in part, one or more legacy SIGNAL fields, one or more high efficiency SIGNAL fields, and one or more channel training fields. The device may cause to send the one or more channel training fields to one or more first devices. The device may determine one or more spatial channel streams associated with at least one of the one or more first devices, the one or more spatial channel streams includes a first stream and a second stream. The device may partition the at least one of the one or more high efficiency SIGNAL fields into, at least in part, a common part and one or more user-specific parts, the one or more user-specific parts includes a first user-specific part and a second user-specific part. The device may cause to send at least one of the one or more user-specific parts using the one or more spatial channel streams.

Abstract: Embodiments of a high-efficiency WLAN (HEW) access point (AP), user device (STA), and methods for communication between HEW APs and STAs in a wireless network are generally described herein. In some embodiments, a HEW AP determines a duration of a low-power time allocation, within a beacon period, that is to be reserved for low-power transmissions by STAs within a service range of the AP. The HEW AP can broadcast time sharing information to STAs within the service range of the AP. The time sharing information can indicate a start time of the duration of the low-power time allocation with respect to a start time of the beacon period and a maximum transmission power for transmissions performed during the low-power time allocation. Other embodiments and methods are also described.
