  • Publication number: 20220141841
    Abstract: Methods, devices and systems for communication techniques that use the quasi-static properties of wireless channels are described. One example method to improve communication performance includes receiving a set of pilots over a transmission channel between the wireless communication apparatus and a far-end communication apparatus, the transmission channel comprising a first portion that is time-invariant and a second portion that is time-variant, processing the received set of pilots to generate an estimate of the first portion, processing the received set of pilots to generate an estimate of the second portion, and performing a communication based on a channel state information that is a weighted combination of a first term based on the estimate of the first portion and a second term based on the estimate of the second portion.

  • Publication number: 20210058114
    Abstract: Described are devices, systems and methods for scheduling multi-user (MU) multiple input multiple output (MIMO) transmissions in a fixed wireless access (FWA) system. One method for scheduling a large number of user devices in a wireless communication system includes a preselection process to pare down the number of user devices to be simultaneously scheduled, and then scheduling that subset of users. In an example, and assuming each user device communicates over a corresponding wireless channel, the preselection process includes determining a number of sets based on a first characteristic of the wireless channels, where each set includes at least one user device, and then determining a subset of user devices by selecting at most one user device from each of the sets. The scheduling of the selected subset of users is based on a scheduling algorithm and a second characteristic of the wireless channels.

  • Patent number: 10020864
    Abstract: Aspects of the subject disclosure may include, for example, a device, process or software that determines an operation between a number of pairs of antennas of a set of antennas. A pair of antennas of the number of pairs of antennas is determined based on the operation. One antenna of the pair of antennas is eliminated from the set of antennas, which results in a reduced number of antennas remaining in the set of antennas. Each of the determining of the operation, the determining of the pair of antennas of the reduced number of antennas and the eliminating of the one antenna of the pair of antennas is repeated in response to the reduced number of antennas being greater than a predetermined number of antennas. Other embodiments are disclosed.

  • Publication number: 20170131402
    Abstract: A method for registering a location of a device with a floor plan of an indoor space determines a portion of the floor plan specifying a coarse location of the device using strength of WiFi signals received from at least three access points (APs). The location of each AP is registered with the floor plan. The method determines at least one distance between the device and at least one object registered with the floor plan using a time-of-flight of at least one acoustic signal and registers the location of the device within the portion of the floor plan at the distance from the object.

    Abstract: A method of channel estimation in an OFDM transmission system having a transmitter and a receiver according to standard IEEE 802.11x. The method includes: in the transmitter, setting an identifier in a reserved bits section of the header following the preamble in a physical layer frame; attaching a postamble at the end of said frame without altering the length information in the header; transmitting said frame over the channel, in the receiver, receiving a frame over the channel and checking a reserved bits section in the header of the received frame for the presence of the identifier; and if the identifier is detected, using the postamble and the preamble of the received frame to estimate the channel.

  • Patent number: 7912014
    Abstract: Interference is reduced with a multiple-input-multiple-output (MIMO) system having a set of basestations including a first basestation and a second basestation is reduced. Signals associated with the first basestation having its own antenna elements are received. The first basestation is associated with its own mobile stations each having their own antenna elements. Each signal associated with the first basestation is uniquely associated with a mobile station associated with the first basestation. Signals associated with the second basestation having its own antenna elements are received. The second basestation is associated with its own mobile stations each having their own antenna elements. Each signal associated with the second basestation is uniquely associated with a mobile station associated with the second basestation. Signals associated with the first basestation are jointly detected in conjunction with the signals associated with the second basestation to produce a set of detected signals.
