Patent number: 11616537Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure describe spatial precoding for inter symbol interference reduction in single carrier. Generally, the described techniques provide for one or more wireless devices (e.g., a user equipment (UE) and a network entity) to determine a weighted sum of several beams, each with a different delay, to form a spatial precoder that increases signal to interference noise ratios while improving signaling quality by diversifying the number of beams carrying subsequent messaging. The one or more wireless devices may determine complex gain values and delay parameters based on reference signals. The one or more wireless devices may utilize the complex gain values and delay parameters such that subsequent transmissions may be received coherently over multiple beams.Type: GrantFiled: February 11, 2022Date of Patent: March 28, 2023Assignee: QUALCOMM IncorporatedInventors: Amit Bar-Or Tillinger, Gideon Shlomo Kutz, Shay Landis, Idan Michael Horn
