Patent number: 11871434Abstract: The method for transmitting control information in a mobile communication system includes: determining a control channel resource for transmitting control information by means of the data channel region; and transmitting the control information using the determined control channel resource. A capacity for control information, which increases for multiple user multiple-input multiple-out (MIMOs) in a heterogeneous network environment, for heterogeneous network interference control using carrier aggregation, for frequent use of a multicast-broadcast single frequency network (MBSFN) subframe, and for a CoMP transmission control, may be satisfied. Further, an adaptive resource allocation based on a requested capacity for control information may be enabled, and the efficient utilization of resources may also be enabled.Type: GrantFiled: February 2, 2023Date of Patent: January 9, 2024Assignee: Electronics and Telecommunications Research Inst.Inventors: Bang-Won Seo, Young-Jo Ko, Tae-Gyun Noh, Jae-Young Ahn

Publication number: 20230413278Abstract: Data transmission and reception is provided by configuring control channels in a wireless communication system using a plurality of carriers. User equipment (UE) may monitor physical downlink control channel (PDCCH) candidates within common search spaces (CSSs) and User Equipment-specific search spaces (USSs). If the UE is configured with cross-carrier scheduling, when two PDCCH candidates originating from a CSS and a USS, respectively, have cyclic redundancy check (CRC) scrambled by the same Radio Network Temporary Identifier (RNTI) and have a common payload size and the same first control channel element (CCE) index, the UE may interpret that only the PDCCH originating from the CSS is transmitted, thereby solving ambiguity of downlink control information (DCI) detection.Type: ApplicationFiled: August 28, 2023Publication date: December 21, 2023Applicant: Electronics and Telecommunications Research InstituteInventors: Young Jo KO, Bang Won SEO, Jae Young AHN

Patent number: RE49158Abstract: The present invention relates a method and apparatus for transmitting/receiving data using multiple codewords in a communication system using SC-FDMA (single carrier frequency division multiple access). A transmitter generates the multiple codewords for user data and transmits the generated multiple codewords. A receiver receives the multiple codewords and sequentially performs decoding and SIC (successive interference cancellation) on the received multiple codewords. Therefore, this structure can minimize a PAPR (peak to average power ratio) and considerably reduces interference between symbols in a frequency selective fading environment.Type: GrantFiled: June 24, 2016Date of Patent: August 2, 2022Assignee: Electronics and Telecommunications Research InstituteInventors: Hee-Soo Lee, Bang-Won Seo, Hyun-Kyu Chung
