The BS receives UL data based on the UL grant in the first subframe, transmits an acknowledgement/non-acknowledgement (ACK/NACK) for the UL data through a physical HARQ indicator channel (PHICH) in subframe i of the first serving cell and receives non-adaptively retransmitted UL data in a second subframe of the second serving cell if a NACK for the UL data has been transmitted through the PHICH in the subframe i of the first serving cell. The first serving cell and the second serving cell use different UL-DL configurations. | 2016-02-18 |
20160050061 | FINGERPRINT AUTHERNTICATED TOUCHSCEEEN CONTOLLED CASCADED 3G-OFDM MOBILE SYSTEMS - Receiving and demodulating in a mobile device Orthogonal Frequency Division Multiplexed (OFDM) modulated signal into OFDM baseband signal for converting OFDM baseband signal into spread spectrum baseband signal for modulating and transmitting the spectrum signal. The spread spectrum baseband signal contains cross-correlated in-phase and quadrature phase baseband signals. Receiving and demodulating a video spread spectrum modulated signal for providing video spread spectrum baseband signal for viewing baseband video signal. Transmitting and receiving OFDM video and voice signals in Video Internet Protocol (ViIP) and in Voice Over Internet Protocol (VoIP) Wi-Fi networks. Processing a touch screen generated signal into a processed touch screen control signal for use by said user, to launch browser from the screen of said mobile device and using a fingerprint generated signal for providing from fingerprint signal a fingerprint authentication signal.

20160050062 | System and Method for Radio Full Duplex - In one embodiment, a method for calibrating a full-duplex radio system includes transmitting, by a first radio transmitter, a first signal and receiving, by a first radio receiver, a first version of the first signal. The method also includes receiving, by a second radio receiver, a second version of the first signal and transmitting, by a second radio transmitter, a second signal. Additionally, the method includes receiving, by the first radio receiver, a received version of the second signal and determining a response from the second radio transmitter to the first radio receiver in accordance with the first version of the first signal, the second version of the first signal, and the received version of the second signal. | 2016-02-18 |
20160050063 | START-STOP SYNCHRONOUS TYPE SERIAL DATA ACQUISITION DEVICE AND START-STOP SYNCHRONOUS TYPE SERIAL DATA ACQUISITION METHOD - The present disclosure provides a start-stop synchronous type serial data acquisition device including: a counter to which a clock signal that defines an acquisition timing of serial data including a start bit is input, and that counts a number of cycles of a clock signal; and a changing section that, according to a transition of the clock signal when the start bit has been input, changes a maximum count value that is counted by the counter, the maximum count value corresponding to the start bit. | 2016-02-18 |
20160050064 | Method, Apparatus, Mobile Communication Terminal, Computer Program and Storage Medium for Adjusting Frequency Error of Terminal - Handling a frequency error (FEQ) of a terminal which includes a plurality of modems using a same clock source includes: obtaining the FEQ, which is a difference between a carrier frequency of a received signal and a nominal frequency for each modem; obtaining a FEQ threshold of the received signal in a current service based on the FEQ; obtaining an adjusted value of the clock source corresponding to each modem based on the FEQ and the FEQ threshold; obtaining a synthesized adjusted value of the clock source based on the adjusted values of all the moderns; and adjusting the frequency of the clock source based on the synthesized adjusted value of the clock source. The FEQ of the mobile communication terminal can be quickly corrected by adjusting the clock source's frequency, and, by considering the FEQ of all the modems, the modems' performances may be balanced. | 2016-02-18 |
