Patent number: 10341997Abstract: Disclosed are a method and a device for transmitting uplink control information (UCI) by a terminal in a wireless communication system. The UCI transmission method comprises the steps of: generating an encoding information bit stream by performing channel coding for a UCI bit stream; generating complex modulation symbols by performing modulation for the generated encoding information bit stream; spreading the complex modulation symbols in block-wise on the basis of an orthogonal sequence; and transmitting the spread complex modulation symbols to a base station. The encoding information bit stream is generated by a channel coding for circularly repeating the UCI bit stream.Type: GrantFiled: January 4, 2018Date of Patent: July 2, 2019Assignee: LG ELECTRONICS INC.Inventors: Seung Hee Han, Ji Woong Jang, Jae Hoon Chung, Han Gyu Cho, Yeong Hyeon Kwon, Seung Hyun Kang

Publication number: 20170041104Abstract: A method is provided for performing data transmission using a hybrid automatic repeat request (HARQ) scheme performed by a transmitter. The transmitter transmits uplink data to a receiver, and receives an acknowledgement (ACK) signal for the data from the receiver. The transmitter determines whether or not an uplink grant associated with the ACK signal is received. The transmitter keeps the uplink data in an HARQ buffer of the transmitter without flushing the uplink data if it is determined that the uplink grant associated with the ACK signal is not received within a certain time period from the receiver.Type: ApplicationFiled: October 24, 2016Publication date: February 9, 2017Applicant: LG Electronics Inc.Inventors: Doo Hyun SUNG, Hyung Ho PARK, Jin Soo CHOI, Jae Hoon CHUNG, Jong Young HAN, Kyu Jin PARK, Eun Jong LEE, Han Gyu CHO
