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.

Embodiments may comprise physical layer logic to implement a new, short acknowledgement. Embodiments may store the short acknowledgement on a machine-accessible medium. Some embodiments may determine and transmit a communication with the short acknowledgement. Further embodiments may receive and detect communications with the short acknowledgement. The short acknowledgement may reduce power consumption and reduce on-the-air time.

Logic may parse a data stream into two or more 80 megahertz or 160 megahertz bandwidth frequency segments. Logic may parse a data stream into two or more frequency segments having a total bandwidth of greater than 160 megahertz. Logic may deparse the data stream prior to transmitting the data stream to transmit a communication with a contiguous bandwidth of greater than 160 megahertz. 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.

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.

Generally, arrangements for enabling direct medium access control (MAC) sublayer data frames are described herein. Embodiments may comprise logic such as hardware and/or code to reduce the size of a packet by determining a frame in the MAC sublayer, inserting the frame in the signal field of a preamble to transmit, transmitting the direct MAC data frame as a packet, communicating that the packet is a direct MAC data frame, and parsing and interpreting the direct MAC data frame at the receiving device. Embodiments may determine and transmit and/or receive and interpret direct MAC data frames.

In some examples, an apparatus for dynamically setting a clear channel assessment (CCA) threshold in a wireless local area network (WLAN) may comprise a processor component, a radio coupled to the processor component, and logic for execution by the processor component to establish a CCA threshold for a wireless channel of the WLAN, send a first wireless message to one or more wireless station (STA) devices in wireless proximity to the apparatus informing the one or more STA devices of the established CCA threshold and instructing the one or more STA devices to avoid CCA levels exceeding the CCA threshold on the wireless channel and send a second wireless message to a wireless access point (AP) device associated with the apparatus informing the AP device of the established CCA threshold and instructing the AP device to broadcast use of the CCA threshold on the wireless channel. Other examples are described and claimed.
