摘要： Embodiments of an access point (AP), user station (STA), and method for spatial modulation orthogonal frequency division multiplexing (SM-OFDM) communication in a wireless network are generally described herein. The AP may transmit an SM-OFDM signal that comprises multiple OFDM signals. The SM-OFDM signal may be transmitted in channel resources that comprise multiple sub-carriers and the OFDM signals may be based at least partly on data symbols for used data portions of the sub-carriers. The used data portions may be based on a first portion of encoded bits and the data symbols for the used data portions may be based on a second portion of the encoded bits. In some examples, the used data portions of the sub-carriers may be different for at least some of the OFDM signals.

摘要： Logic such as hardware and/or code to narrow available sub-channels in frequency selective transmission communications in which a station selects a narrow band from a wider channel bandwidth. A frequency selective transmission scheme for communications devices may select a 1 or 2 MHz channel from a wider channel bandwidth (e.g., 4, 8, 16 MHz) that consists of a number of 1 or 2 MHz sub-channels and transmitting packets on the selected sub-channel. The access point may narrow the number of sub-channels available for selection by stations. Stations may narrow the number of sub-channels. Both the AP and the stations may operate to narrow the number of sub-channels. A medium access control sub-layer protocol common to the communications devices may facilitate a frequency selective transmission scheme.

In some embodiments, the access point may be configured to operate as a master station and may configure an HEW frame to include a legacy signal field (L-SIG), an HEW signal field (HEW SIG-A) following the L-SIG, and one or more HEW fields following the HEW SIG-A. The L-SIG may be configured for transmission using a legacy number of data subcarriers, a legacy number of pilot subcarriers and a number of additional reference subcarriers modulated with a known reference sequence. At least one symbol of the HEW SIG-A and the one or more HEW fields following the HEW SIG-A of the HEW frame may be configured for transmission using additional data subcarriers. The additional data subcarriers may correspond to the additional reference subcarriers of the L-SIG.
