    Abstract: A method and apparatus for concurrent wireless communications on multiple channels of the same frequency band. A wireless device receives a first data signal via a first transceiver chain while concurrently initiating a transmission of a second data signal via a second transceiver chain of the wireless device. The wireless device suspends updates to one or more tracking loops of the first transceiver chain in response to initiating the transmission of the second data signal. The updates to the one or more tracking loops may be suspended prior to transmitting the second set of data from the second transceiver chain. The wireless device may subsequently resume updates to the one or more tracking loops of the first transceiver chain after completing the transmission of the second data signal.

    Abstract: Methods, apparatus, and computer-readable media for wireless communication may involve techniques for throughput estimation. An expected air time parameter may be used as a parameter for estimating throughput. The expected air time parameter may be indicative of an estimated air time fraction obtainable for communications using an access point (AP), for example, between a wireless station (STA) and the AP. Either the expected air time parameter or an estimated air time fraction determined (e.g., calculated) from the expected air time parameter may be transmitted from the AP to the STA (or other communication device) to allow the STA (or other communication device) to determine an estimated throughput for communications using the AP.

    Abstract: A method of determining a channel response of a communications channel. A computing device receives a data packet via the communications channel and generates a first channel estimation based on a first portion of a preamble of the received data packet. The computing device further generates a second channel estimation based on a second portion of the preamble and determines the channel response of the communications channel based, at least in part, on an average of the first and second channel estimations. For example, the first portion of the preamble may correspond with a Long Training Field (LTF), and the second portion of the preamble may correspond with a Very High Throughput Signal B (VHT-SIG-B) field.

    Abstract: A wireless transmitter can include a plurality of bandwidth modules, each bandwidth module processing data based on a predetermined frequency band. In one embodiment, such a wireless transmitter can include encoding components for receiving transmit data and generating encoded data. A multiple-input multiple-output (MIMO) stream parser can receive the encoded data and generate a plurality of MIMO streams. A first module parser coupled to a first MIMO stream can generate a first plurality of partial MIMO streams. A first bandwidth module can include a first interleaver that interleaves bits of the first partial MIMO stream and generates first interleaved data. A second bandwidth module can include a second interleaver that interleaves bits of the second partial MIMO stream and generates second interleaved data. A first inverse fast Fourier transform (IFFT) unit can combine and process the first and second interleaved data and generate a first transmission MIMO stream.
