Patent number: 9577809Abstract: A method for transmitting ACK/NACK (Acknowledge/Negative ACK) information at a user equipment in a wireless communication system, and a user equipment therefore are discussed. The method according to one embodiment includes generating an ACK/NACK payload for a plurality of carriers, the ACK/NACK payload including a plurality of concatenated ACK/NACK sets. Each ACK/NACK set is associated with a respective one of the plurality of carriers and has one or more ACK/NACK bits. The method further includes transmitting the ACK/NACK payload through a PUCCH (Physical Uplink Control Channel) or PUSCH (Physical Uplink Shared Channel). The ACK/NACK payload includes an ACK/NACK bit for a semi-persistent scheduled downlink signal. The ACK/NACK bit for the semi-persistent scheduled downlink signal is positioned at an end of a corresponding ACK/NACK set, not an end of the ACK/NACK payload.Type: GrantFiled: February 25, 2016Date of Patent: February 21, 2017Assignee: LG ELECTRONICS INC.Inventors: Jae Hoon Chung, Hyun Woo Lee, Young Hyoun Kwon, Ji Woong Jang, Seung Hee Han

Patent number: 9559794Abstract: A signal detection apparatus includes a signal reception unit, an Analog to Digital (A/D) signal processing unit, and a user interface unit. The signal reception unit receives an external signal. The A/D signal processing unit determines whether the received signal is an abnormal signal based on a plurality of signal profiles having different signal characteristics, and obtains the abnormal signal if, as a result of the determination, it is determined that the received signal is the abnormal signal. The user interface unit displays the abnormal signal.Type: GrantFiled: October 27, 2013Date of Patent: January 31, 2017Assignee: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Young-Hyoun Kwon, Kyung-Hoon Lee, Hui-Rae Cho, Jae-Ki Lee, Hee-Sun Park, Jin-Gak Jang, Jin-Hyun Kim, Ji-Eun Kim, In-Ho Hwang, Chun-Soo Kim

Patent number: 9306706Abstract: A method for transmitting ACK/NACK (Acknowledge/Negative ACK) information for two or more carriers at a user equipment in a wireless communication system which supports carrier aggregation. The method according to one embodiment includes generating an ACK/NACK payload including two or more ACK/NACK sets, wherein each ACK/NACK set is associated with a corresponding carrier and have one or more ACK/NACK bits; and transmitting the ACK/NACK payload through a PUCCH (Physical Uplink Control Channel) or PUSCH (Physical Uplink Shared Channel). A size of the ACK/NACK payload is given based on carrier configuration, the carrier configuration including a number of configured carriers and transmission modes for the configured carriers. The two or more ACK/NACK sets are concatenated in an order of carrier index.Type: GrantFiled: March 13, 2015Date of Patent: April 5, 2016Assignee: LG Electronics Inc.Inventors: Jae Hoon Chung, Hyun Woo Lee, Young Hyoun Kwon, Ji Woong Jang, Seung Hee Han
