Abstract
Embodiments of a high efficiency (HE) access point (HE AP) and HE station (HE STA) are generally described herein. The HE AP may transmit a frame that includes a transmit power envelope element to indicate local maximum transmit power constraints for an operating bandwidth of the HE AP on a per-segment basis. The operating bandwidth may be configurable for division into segments of a configurable segment size. The transmit power envelope element may include: a transmit power information field that includes: a local maximum transmit power count subfield that indicates the operating bandwidth, and a segment size subfield that indicates the segment size; and for each of the segments, a local maximum transmit power per segment field that indicates a local maximum transmit power for the segment.
