  • Patent number: 10742379
    Abstract: A method of uplink control information (UCI) transmission over physical uplink control channel (PUCCH) is proposed. The UCI may include different information and being transmitted using different PUCCH formats. Under certain scenarios, the coded UCI bitstream size may not be assigned to an integer number of modulated symbols. To eliminate unnecessary processing as well as to utilize every bit in a modulated resource element, it is proposed to adjust the UCI codeword size to be a multiple of PUCCH modulation order.

  • Patent number: 10320494
    Abstract: An integrated circuit (IC) is provided. The IC includes an RF transmitter and an RF receiver. The RF transmitter is configured to generate an RF signal in response to an analog test signal from a test signal generator of a module circuitry that is external to the IC. The RF receiver is configured to generate an outgoing signal according to an input RF signal, and to report the outgoing signal to the module circuitry. The module circuitry performs a test analysis on the RF signal generated by the RF transmitter or on the outgoing signal generated by the RF receiver to determine a test result. The test result is reported to a test equipment having no RF instruments.

  • Patent number: 9525500
    Abstract: A test/calibration system includes a device under test (DUT) and a calibrated device. The calibrated device is coupled to the DUT, transmits or receives a test signal to or from the DUT in response to a control signal for a test item to test, measure or calibrate functioning or performance of an internal component of the DUT.

  • Publication number: 20160197684
    Abstract: An integrated circuit (IC) is provided. The IC includes: a controller, a serializer-deserializer (SerDes) device, a transmitter, and a receiver. The controller is configured to obtain a test signal when the IC has entered a test mode. The SerDes device is configured to perform a serialization/deserialization process on the test signal. The transmitter is configured to generate a radio frequency (RF) signal in response to the test signal after the serialization/deserialization process. The RF receiver is configured to receive the RF signal in the test mode. The controller further captures the received RF signal from the receiver for determining a test result.

  • Publication number: 20120269284
    Abstract: A method of transmitting a plurality of data symbols for a transmitter in a wireless communication system is disclosed. The method comprises encoding the plurality of data symbols into a plurality of precoded symbols according to an antipodal paraunitary (APU) precoding; processing the plurality of precoded symbols by using multi-input multi-output (MIMO) and orthogonal frequency-division multiplexing (OFDM), for generating a plurality of transmission symbols; and transmitting the plurality of transmission symbols via a plurality of transmit antennas according to operations of the MIMO and the OFDM.
