  • 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.

The base station (20) requests at least two terminals (11-13) to transmit pilot signals in the allocated pilot time slot in such a manner that the at least two terminals (11, 12; 11-13) are prevented from transmitting their pilot signals simultaneously.

  • Patent number: 10045148
    Abstract: Apparatuses, methods, and computer-readable media for a proximity-based connection facilitation device (“PBC”) may be described which may facilitate discovery and connection to computing devices. The PBC may present visual elements representing devices based on their locations, such as their proximity to the PBC. The PBC may present visual elements for a limited set of devices. The PBC may present computing devices in a visual manner that may depict their proximity to the PBC. The PBC may also provide for facilitated connection to devices that are not as proximate to the PBC. The PBC may facilitate identification of devices that are proximate to an identified device. By facilitating a user in selecting a first device and then visualizing devices proximate to the first device, the PBC may facilitate a user in chaining from a first device to devices that are less easily identified. Other embodiments may be described and/or claimed.

  • Patent number: 10028095
    Abstract: Embodiments of the invention generate metrics quantifying the mobility of a mobile device without persisting information related to the device's specific location at any given time. Specifically, at multiple intervals, a value of a mobility metric is computed based on the distance between the current location of the mobile device and a previously identified origin location of the mobile device. The values of the mobility metric computed over a period of time quantify the overall mobility of the mobile device. The mobility metric does not provide any information regarding the specific location of the mobile device at any given time.

  • Patent number: 10015696
    Abstract: A Physical Broadcast Channel (PBCH) Interference Cancellation (PBCH-IC) solution is presented herein. The PBCH-IC provides accurate and efficient techniques for cancelling interference from a serving cell PBCH. In one embodiment, PBCH symbols previously determined for an aggressor cell are canceled from a PBCH sequence currently received by the wireless device to produce a serving cell PBCH free of interference. In another embodiment, the PBCH symbols of the aggressor cell are reconstructed in the frequency domain and converted to the time domain to generate an aggressor PBCH sequence. The aggressor PBCH sequence is then subtracted from the received PBCH sequence to cancel the aggressor cell interference.
