Patent number: 10952169Abstract: The present invention relates to a 5th-generation (5G) or pre-5G communication system to be provided in order to support a higher data transmission rate than a beyond 4th-generation (4G) communication system such as long term evolution (LTE). The present invention relates to a signal transmission method of a radio frequency (RF) processing device, the method comprising the steps of: generating a pulse signal including a control signal and a clock signal for obtaining synchronization with another RF processing device, which is connected through an interface; and transmitting, to the another RF processing device, at least one from among the pulse signal, a RF signal for communication with a base station, and a power signal for supplying power to the another RF processing device, wherein the clock signal and the control signal are assigned to different time units, and the pulse signal, the RF signal and the power signal are signals of different frequency bands.Type: GrantFiled: September 15, 2015Date of Patent: March 16, 2021Assignee: Samsung Electronics Co., Ltd.Inventors: Dae-Young Lee, Chul-Woo Byeon, Ju-Ho Son, Jeong-Ho Lee, Sun-Kyu Choi, Sung-Tae Choi

Patent number: 10505647Abstract: An apparatus and a method for phase calibration in a radio frequency (RF) module that constitutes a wireless communication device are provided. The apparatus and method include a test signal is emitted by a forward transmission antenna array of a first antenna array, and the emitted test signal, which is transferred by a member that covers the first and second antenna arrays, is received through a forward reception antenna array of the second antenna array. On the basis of the received test signal, a phase value is calibrated with regard to each of chain combinations formed by the first and second antenna arrays. Forward chain combinations that constitute the chain combination may be determined by a combination of forward transmission chains, which correspond to respective transmission antennas that constitute the forward transmission antenna array, and forward reception chains, which correspond to respective reception antennas that constitute the forward reception antenna array.Type: GrantFiled: July 11, 2016Date of Patent: December 10, 2019Assignee: Samsung Electronics Co., Ltd.Inventors: Dae-Young Lee, Chul-Woo Byeon, Ju-Ho Son, Jeong-Ho Lee, Mee-Ran Kim

Patent number: 10028222Abstract: An apparatus and method for controlling power in a communication system are provided. The method includes amplifying an input signal by a second processor farther from an antenna than a first processor, and determining whether to enable or disable each of the first processor and the second processor based on results from the amplification by the second processor. Another method includes amplifying an input signal from an antenna by a second processor electrically farther from the antenna than a first processor, and determining whether to operate the first processor and the second processor based on a value related to a reception state for the amplified signal by the second processor.Type: GrantFiled: December 31, 2015Date of Patent: July 17, 2018Assignee: Samsung Electronics Co., Ltd.Inventors: Ju-Ho Son, Jeong-Ho Lee, Chul-Woo Byeon, Dae-Young Lee, Sun-Kyu Choi
