摘要： Devices and methods of providing communications between a Low-Power (LP) STA and an Assisting STA are generally described. Different TXOPs are used for communication with the LP STA with an AP. A wideband preamble is transmitted on a 20 MHz channel and a narrowband trigger frame on a 2 MHz subchannel of the channel. A narrowband response is transmitted from the LP STA to the Assisting STA in response to transmission of the trigger frame. The response contains predetermined duration of data and an address of the Assisting STA and/or AP. The response potentially has a transmission range less than a distance from the LP STA to the AP. A narrowband ACK is transmitted in response to reception of the response. The trigger frame, the response and the ACK use the same subchannel. After reception of the response, a wideband communication containing the data is transmitted from the Assisting STA to the AP.

Logic may deparse the data stream prior to space-time block coding of the data stream. Logic may transmit the data stream in two or more frequency segments having a total bandwidth of greater than 160 megahertz. Logic may receive a communication with a contiguous bandwidth or two or more frequency segments with contiguous or non-contiguous bandwidths. Logic may parse a communication with a contiguous bandwidth into two or more frequency segments. And logic may deparse the frequency segments to decode the communication.

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.
