Abstract
Methods, systems and apparatus related to index modulation for WLAN (IEEE 802.11) are provided. An information-carrying bit sequence to be transmitted is separated into two parts. The first part is used as the basis for selecting tones from distributed resource units (DRUs) which are defined for use in transmission of a frame. The second part is used as the basis for generating modulation symbols for transmission. The modulation symbols are then transmitted using the selected tones. At the receiver, the tones which are used are determined by an energy detection method, and the modulation symbols are also decoded. A recovered bit sequence is generated based on the determined tones and the modulation symbols. Where there are N DRUs, each having T tones, T groups of tones can be defined. From each group of tones, one tone is selected based on a sub-part of the bit sequence's first part.
