Abstract: A system comprising a processing circuitry configured to: obtain a first ordered sequence of symbols associated with a corresponding second ordered sequence of transmitted symbols and including one or more errors, the errors being discrepancies between given symbols of the first ordered sequence and corresponding symbols of the second ordered sequence; determine, for each symbol of the first ordered sequence of symbols, an estimated transmitted symbol, utilizing a Decision Feedback Equalizer (DFE); and determine if the estimated transmitted symbol of a given symbol of the first ordered sequence of symbols, satisfies a saturation threshold condition; and determine an error hypothesis identifying one or more of the errors by comparing the estimated transmitted symbol of at least one symbol of the first ordered sequence of symbols with one or more pairs of thresholds.

Abstract: A rate Detection Apparatus (RDA) includes a power spectral density (PSD) estimator and a rate selector. The PSD estimator is configured to receive samples of a signal, and to estimate a PSD of the signal. The rate selector is configured to identify a transmission rate of the signal responsively to the estimated PSD.

Abstract: Techniques and apparatus for efficiently performing rate selection and transmit gain selection are provided. The techniques may be performed, for example, by a transmitting entity in the absence of explicit MCS selection reporting by a receiving entity. One technique includes outputting first packets for transmission using a first modulation and coding scheme (MCS) value and via a transmit power amplifier (PA) configured according to a transmit gain parameter associated with the first MCS value. Feedback indicating whether the first packets have been received is obtained, a second MCS value for second packets is selected based on the feedback, and the transmit gain parameter is adjusted if one or more criteria are met. Second packets are output for transmission using the second MCS value and, thereafter, additional packets are output for transmission based on the first MCS value and the adjusted transmit gain parameter.

Abstract: Certain aspects relate to methods, apparatuses, computer readable mediums and wireless nodes. For example, an apparatus generally includes (a) a processing system configured to (i) obtain a TXOP, (ii) generate a plurality of first frames, wherein one or more of the first frames include a control field having a first value and one or more of the first frames include data and (iii) apply a first MCS to the plurality of the first frames and (b) an interface configured to (i) output the modulated and coded first frames for transmission to a second apparatus during the TXOP, wherein the first value indicates the second apparatus can only transmit control information during the TXOP and (ii) obtain, during the TXOP, an ACK indicating data of at least one of the first frames was received by the second apparatus.

Abstract: Certain aspects relate to methods, apparatuses, computer readable mediums and wireless nodes. For example, an apparatus generally includes an interface configured to obtain, during a TXOP owned by a second apparatus, at least one first frame from the second apparatus and a processing system configured to (i) determine a MCS associated with the at least one first frame, (ii) increase a value of a counter if the MCS associated with the at least one first frame is the same as a MCS associated with a frame previously obtained by the apparatus during the TXOP and (iii) take one or more actions based on the counter value.

Abstract: Techniques for multiplexing pilots in a wireless transmission are described. In one aspect, a transmitter station generates multiple pilot sequences for multiple transmit antennas, with each pilot sequence comprising pilot symbols sent in the time domain on a different set of subcarriers. The transmitter station further generates multiple pilot transmissions for the transmit antennas based on the pilot sequences. In another aspect, a transmitter station generates multiple pilot sequences for multiple transmit antennas based on frequency-domain code division multiplexing (FD-CDM) of a Chu sequence defined by a transmitter-specific value. The transmitter station further generates multiple pilot transmissions for the transmit antennas based on the pilot sequences.

Abstract: Methods and apparatus for selectively invoking receive diversity during power-up/initial acquisition and out of service modes are disclosed. A method can include selectively enabling receive diversity based on an initial acquisition attempt by one of the receive chains in a wireless device having multiple receive chains. A method can also include enabling receive diversity based on a predetermined list of channels to be acquired. A predetermined list of channels is a subset of a plurality of channels that may be acquired. Other aspects, embodiments, and features are also claimed and described.
