Publication number: 20230283989Abstract: A mobile device may be configured to perform concurrent Satellite Positioning System (SPS) operation and wireless communications when uplink signals transmitted by the mobile device interferes with the reception of SPS signals in one or more frequency bands. The mobile device may determine if the SPS receiver has already acquired SPS signals and is in a tracking state. If the SPS receiver is not in a tracking state, an SPS acquisition procedure is initiated before the wireless communication session is initiated. The SPS acquisition procedure is performed until the SPS receiver reaches a tracking state, or until a timeout is reached. Once the SPS receiver is in a tracking state, the wireless communication session may be initiated, during which the SPS receiver is controlled, e.g., to perform signal blanking, measurement exclusion, or disable SPS reception, to mitigate interference with SPS signals.Type: ApplicationFiled: March 31, 2023Publication date: September 7, 2023Inventors: Jordan COOKMAN, Liang ZHAO, Angelica WONG, Krishnaranjan RAO, Chang ROW

Patent number: 9450646Abstract: An NFC initiator device requests a passive communication mode by modulating a request onto a first carrier signal. In response thereto, the target device transmits a second carrier signal while still receiving the first carrier signal from the initiator device.

Publication number: 20160149735Abstract: Systems and methods relate to extracting a small sideband signal from a received signal having the small sideband with a small frequency offset from a large carrier signal. The received signal is down-converted from a transmission frequency and the large carrier signal is filtered out. A threshold comparator is configured to compare the resultant sideband signal with a first signal threshold and a second signal threshold. If the sideband signal exceeds the first signal threshold in a first direction, the sideband signal is restored to a data signal with a first data value. The restored data signal is retained at the first data value until the sideband signal exceeds a second signal threshold in a second direction, at which time the sideband signal is restored to the data signal with a second data value.Type: ApplicationFiled: November 21, 2014Publication date: May 26, 2016Inventors: Angelica WONG, Haitao GAN
