    Abstract: Some new low power architecture devices may, e.g., be associated with in a new device category in the IEEE 802.11ah Standard for devices with low power architecture. Some new low power architecture devices may only to support a subset of modulation and coding schemes (MCSs). Some new low power architecture devices negotiate the use of the subset of MCSs with an access point. Further new low power architecture devices address power consumption through modifications to the architecture of the new low power device. For instance, many new low power architecture devices remove, modify or bypass portions of the front-end transmitter circuitry and/or the front-end receiver circuitry such as a power amplifier, a low noise amplifier, predistortion circuitry, digital-to-analog and analog-to-digital converter resolutions, and stages of filtering.

    Abstract: This document discusses, among other things, apparatus and methods for transmit beamforming sounding. An example method for communicating over a wireless network having multiple sub-carrier frequencies can include assigning a first pilot signal to a first sub-carrier frequency for transmission with a first symbol, transmitting the first symbol from a first wireless device, receiving the first symbol at a second wireless device, determining channel time and phase offset using the first pilot signal, and estimating transmit beamforming channel state information using the first pilot signal.

    Abstract: An approach is provided for defining a 1 MHz preamble of a packet. The approach involves determining a preamble sequence of a packet, the preamble sequence having a determinable length. The approach also involves causing, at least in part, the preamble sequence to be divided into a predetermined number of blocks. The approach further involves causing, at least in part, a mathematical operation and a summation over the predetermined number of blocks and a corresponding number of received blocks. The approach also involves causing, at least in part, the summation to be maximized to determine the preamble sequence corresponds to one of a first bandwidth or a second bandwidth, the second bandwidth being greater than the first bandwidth, to determine a type of the packet.

    Abstract: Logic for collision mitigation between transmissions of wireless transmitters and receivers operating at different bandwidths. Logic of the receivers may be capable of receiving and detecting signals transmitted at narrower bandwidths. In several embodiments, the receivers comprise a clear channel assessment logic that implements a guard interval (or cyclic prefix) detector to detect transmissions at narrower bandwidths. For instance, a two MegaHertz (MHz) bandwidth receiver may implement a guard interval detector to detect 1 MHz bandwidth signals and a 16 MHz bandwidth receiver may implement logic to detect one or more 1 MHz bandwidth signals and any other combination of, e.g., 1, 2, 4, 8 MHz bandwidth signals. In many embodiments, the guard interval detector may be implemented to detect guard intervals on a channel designated as a primary channel as well as on one or more non-primary channels.
