  • Patent number: 10135551
    Abstract: The method of identifying faulty antenna elements in massive uniform linear antenna arrays is a compressive sensing-based method that takes advantage of the reduction of the measurement matrix for a uniform linear antenna array to a partial discrete Fourier transform (DTF) matrix, whose rows correspond to the measurements' locations. Particularly, the method of identifying faulty antenna elements in massive uniform linear antenna arrays allows the measurements to be taken to reduce the measurement matrix's worst-case coherence, a factor which affects the detection probability of the defective antenna elements. The method constructs a measurement matrix with fewer distinct inner product values to reduce the worst-case coherence. In an alternative embodiment, the method focuses on bounding the inner product between any pair of measurement matrix columns.

  • Patent number: 10108903
    Abstract: In a general aspect, motion in a space can be detected based on machine learning of wireless signal properties. In some aspects, sets of tagged neural network input data are obtained at a neural network training system. Each set of tagged neural network input data is based on a statistical analysis of a series of wireless signals transmitted through a space over a respective time period, and each set of the tagged neural network input data includes a tag indicating whether motion occurred in the space over the respective time period. The sets of tagged neural network input data are processed by the neural network training system to parameterize nodes of a neural network system. Parameterizing the nodes configures the neural network system to detect motion based on untagged neural network input data.

    Abstract: A wireless device determines a calculated power for a plurality of signals comprising: a first sounding reference signal (SRS) configured for transmission in a subframe of a licensed assisted access (LAA) cell type and a second SRS configured for transmission in the subframe of a licensed cell type. The wireless device drops or scales at least one of the first SRS or the second SRS based on a transmit power priority. The transmit power priority considers whether the first SRS or the second SRS is configured for transmission on the licensed cell type or the unlicensed cell type.

  • Patent number: 9973408
    Abstract: A method and apparatus of measuring a packet throughput in a wireless communication system are provided. When determining a reference time for estimating packet throughput, a receiver determines the time that a data burst starts or ends in order to estimate the packet throughput considering a change in the data burst of the transmitter buffer. A measurement period is defined through the determined start time and end time of the data burst, and packet throughput is measured considering the total amount of the received data burst. The throughput of packet data may be estimated by each base station based on the same standard rule, so that the measured packet throughput values may be reliable, thus allowing the operator to make use of it as a parameter for MDT.

  • Patent number: 9967754
    Abstract: Monitoring non-supported wireless spectrum within a coverage area of a distributed antenna system (DAS) in which a listening module connected to a remote unit of the DAS monitors non-supported wireless frequencies (i.e., frequencies that are outside the frequency ranges supported by the downlink and uplink signals of the DAS), via one or more antennas. The listening module also transmits the wireless frequencies to a monitoring module connected to head-end equipment (HEE) of the DAS. In that manner, a monitoring module can use an existing DAS infrastructure to monitor non-supported portions of the wireless spectrum at remote locations. In addition to avoiding the need to run a parallel DAS infrastructure, the disclosed arrangements are also useful in shared spectrum environments and other environments where efficient spectrum utilization is desired.

  • Patent number: 9948486
    Abstract: The apparatus enables pilot signals, whether single tone or multiple tone, that achieve a very low PAPR. After receiving an allocation for multiple tones, the apparatus determines a pilot signal for transmission. The apparatus may select tones from the allocation for transmission of a pilot signal based on a pilot pattern. The pilot pattern may comprise a tone sequence that identifies a sequences of tones, wherein each tone in the tone sequence of identifies one tone of multiple tones for transmission of a pilot signal during a given pilot symbol period. The pilot signal may also comprise a signal sequence. The apparatus may generate a set of multi-tone modulated pilot sequences, select a pilot sequence based on a cross-correlation property, and transmit a pilot signal using multiple tones of the allocation using the selected pilot sequence.

  • Patent number: 9936444
    Abstract: Methods and systems for wireless stations to wirelessly exchange configuration information using the vendor specific field of management frames (e.g. Wi-Fi™ probe request frames, Wi-Fi™ beacon frames or Wi-Fi probe response frames). Each wireless station can then use the configuration information to configure itself for a particular application or task. For example, the wireless stations may use the configuration information to determine the appropriate topology of a collection of wireless stations for the application or task. Using the management frames to exchange configuration information allows the wireless stations to exchange configuration information without being fully connected to a wireless network. This then allows the wireless stations to exchange configuration information while they are operating in a low-power mode (e.g. in a mode where the network stack is disabled).

  • Patent number: 9930539
    Abstract: Methods, systems, and devices for wireless communication are described. A base station may select a repetition level for a physical broadcast channel (PBCH) based on system configuration parameters. A user equipment (UE) may identify the system configuration. For example, the UE may assume a system bandwidth, assume a control region size, and determine whether the cell is a time division duplexing (TDD) or frequency division duplexing (FDD) cell. The UE may then determine a PBCH configuration based on the system configuration. For example, the PBCH repetition level may depend on the system configuration, such as whether a TDD or FDD scheme is employed. The UE may then receive a PBCH transmission according to the PBCH configuration. If a different cell has a different system configuration, the UE may determine a different PBCH configuration and receive PBCH using a different repetition level and different resources.
