Abstract: Apparatuses and methods for correcting a distorted signal at a receiver device during wireless local area network (WLAN) communications are disclosed. The apparatuses and methods include receiving, by a receiver device in a WLAN, a distorted signal corresponding to a data packet signal transmitted from a transmitter device, receiving, by the receiver device, one or more transmitter parameters corresponding to the transmission of the data packet signal, the one or more transmitter parameters including information to adjust the distorted signal, and adjusting, by the receiver device, the distorted signal to reconstruct the data packet signal based at least on the one or more transmitter parameters.

Abstract: A method for wireless communication is described herein. The method may include advertising support by a wireless device for a first bandwidth mode and a second bandwidth mode, wherein the first bandwidth mode utilizes a single channel and the second bandwidth mode utilizes channel bonding between a plurality of channels. The method may also include switching a current bandwidth mode of the wireless device from one of the bandwidth modes to the other of the bandwidth modes and adjusting a number of multiple-input, multiple-output (MIMO) spatial streams supported by the wireless device in response to the switching.

Abstract: Methods, systems, and apparatuses are described for wireless communications. More particularly, an access point (AP) identifies a plurality of multi-user multiple-input multiple-output (MU-MIMO) groups associated with a wireless station (STA). The AP determines a communication metric associated with each of the plurality of MU-MIMO groups. The communication metric provides an indication of the compatibility of the STAs in the MU-MIMO group. The AP prioritizes at least one of the plurality of MU-MIMO groups based at least in part on the communication metric associated with the prioritized MU-MIMO group. The AP creates a preferred group list and/or a blacklisted group list and included the prioritized MU-MIMO group in the appropriate group list.

Abstract: In an aspect a transceiver is provided. The transceiver may include a plurality of local oscillator (LO) generators configured to generate a plurality of LO signals, respectively, for mixing with one or more communication signals. The transceiver also includes a first synthesizer configured to generate a first reference signal and a second synthesizer configured to generate a second reference signal. The transceiver also includes a distribution circuit. The distribution circuit is configured to switch an input to at least one of the LO generators between the first and second reference signals for tuning each of the at least one of the LO generators between two different LO frequencies and to input to the other ones of the LO generators the first reference signal for tuning each of the other ones of the LO generators to an LO frequency.

Abstract: Method and systems are disclosed for qualifying a wireless device as frequency hopping device. In some aspects, an access point (AP) may determine a frequency hopping pattern for the wireless device, and then allocate a sequence of unique resource units to the wireless device based on the frequency hopping pattern. Each of the unique resource units include a different set of frequency subcarriers. The AP may receive a series of uplink orthogonal frequency-division multiple access (OFDMA) transmissions from the wireless device on the allocated sequence of unique resource units.

Abstract: Systems and methods for communicating packets having a plurality of formats are described herein. In some aspects, a signal (SIG) field in the preamble of a packet may indicate whether an extension field, such as an extension SIG field or SIG-B field, is included in the packet. In another aspect, one or more detectors may be used to auto-detect packets formatted as one of at least two different formats based on a short training field (STF) of a received packet. In some aspects, along training field (LTF) in the preamble of a packet may indicate whether the payload is repetition coded.
