Patent number: 11863329Abstract: According to an aspect, a transmitting device determines, for each of a plurality of transmissions, whether user data to be transmitted within a time transmission interval, TTT, will be closest in time to a DMRS transmitted before the user data or after the user data. If before the user data, all HARQ ACK/NACK data for the transmission is mapped to the earliest in time SC-FDMA symbol carrying user data in the transmission, and to pre-DFT symbols closest in time to the DMRS transmitted before the user data. If after the user data, all HARQ ACK/NACK data for the transmission is mapped to the last in time SC-FDMA symbol carrying user data in the transmission, and to pre-DFT symbols closest in time to the DMRS transmitted after the user data. SC-FDMA signals are formed from user data and control information for the transmission, based on the mapping.Type: GrantFiled: August 11, 2017Date of Patent: January 2, 2024Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Henrik Sahlin, Daniel Larsson, Laetitia Falconetti, Jingya Li, Gustav Wikström

Patent number: 11646855Abstract: Short Control Channel Elements (SCCE) to Short Resource Element Groups (SREG) mapping for Short Physical Downlink Control Channel (SPDCCH) is provided. A User Equipment (UE) receives a communication from a base station; determines a mapping between one or more SCCE and corresponding SREG; and processes the communication based on the mapping. A base station determines a mapping between one or more SCCE and corresponding SREG for a communication to a UE and transmits a communication to the UE based on the mapping. In this way, the localized and distributed SCCE to SREG mapping for CRS-based SPDCCH is defined. Also, the SCCE to SREG mapping for 2 and 3 OFDM symbols DMRS-based SPDCCH is defined. For DMRS-based SPDCCH, a distributed configuration at SCCE level is defined. This may improve latency and can improve the average throughput of a communications system. Radio resource efficiency could be positively impacted by latency reductions.Type: GrantFiled: April 27, 2022Date of Patent: May 9, 2023Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: John Camilo Solano Arenas, Laetitia Falconetti, Niklas Andgart
