Publication number: 20230379025Abstract: Systems and methods for Channel State Information (CSI) enhancements are provided. In some embodiments, a method performed by a wireless device for reporting channel conditions includes one or more of: receiving a Channel State Information-Interference Measurement (CSI-IM) pattern; and reporting channel conditions based on the CSI-IM pattern. In some embodiments, the CSI-IM pattern spans multiple Orthogonal Frequency-Division Multiplexing (OFDM) symbols on a single subcarrier in a slot. In this way, these CSI-IM patterns might allow better interference measurement by capturing interference in all OFDM symbols in a slot and thus more accurate interference estimation and CSI feedback. The enhanced aperiodic CSI might allow interference variations over time to be measured and reported so that proper margins can be applied by the base station in downlink scheduling to ensure reliable data delivery while maintaining high spectrum efficiency.Type: ApplicationFiled: October 12, 2021Publication date: November 23, 2023Inventors: Shiwei Gao, Siva Muruganathan, Jonas Fröberg Olsson, Yufei Blankenship, Zhipeng Lin
