Abstract

Methods, apparatuses, and computer readable media for high efficiency (HE) beacon and HE formats in a wireless network are disclosed. An apparatus of a high efficiency (HE) access point (AP), where the apparatus comprises processing circuitry configured select a <HE-MCS, NSS=1> tuple from the basic HE-MCS set of tuples, if a basic HE modulation and control scheme (MCS)(HE-MCS) and a number of spatial streams (NSS) set of tuples is not empty, and otherwise select the <HE-MCS, NSS=1> tuple from a mandatory HE-MCS and NSS set of tuples. The processing circuitry may be further configured to encode a beacon frame in a HE single user (SU) physical layer (PHY) protocol data unit (PPDU), in accordance with the selected <HE-MCS, NSS=1> tuple, and configure the HE AP to transmit the HE SU PPDU. Null data packets formats, methods, computer readable media, and apparatuses are disclosed for multiple 20 MHz operations.
