Patent number: 11411683Abstract: Described are methods for interference detection and management in a millimeter wave communications system. A V2X communications system may support interference management procedures that comprise scheduling a system wide training interval in a transmission timeslot, suspending traffic transmissions on a link in the communications system during the training interval to perform training on the link, and resuming traffic transmissions on the link if interference is not detected during the training interval. Interference management procedures may also include receiving at a node, unique parameters transmitted from another node in a communication system during a discovery stage, determining whether interference will occur at the node based on the received unique parameters, and suspending transmissions to and from the node if it is determined interference will occur at the node.Type: GrantFiled: January 28, 2019Date of Patent: August 9, 2022Assignee: Qualcomm IncorporatedInventors: Zhibin Wu, Sudhir Kumar Baghel, Junyi Li, Libin Jiang, Kapil Gulati, Shailesh Patil, Tien Viet Nguyen

Patent number: 11343666Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a wireless device may broadcast a discovery preamble to identify a receiving device or to identify a suitable beam for communicating with a receiving device prior to broadcasting a discovery message to the receiving device. In such systems, the wireless device may use the techniques described herein to generate the discovery preamble and to reduce interference between discovery preamble transmissions and avoid data loss. In one example, a wireless device may append a cyclic prefix (CP) to a discovery preamble with a suitable length to protect the discovery preamble from interference from another transmission. In another example, the wireless device may generate a cyclically periodic signal including multiple copies of the discovery preamble so a receiving device may be able to receive a portion of the signal and identify the discovery preamble.Type: GrantFiled: January 3, 2019Date of Patent: May 24, 2022Assignee: QUALCOMM IncorporatedInventors: Navid Abedini, Zhibin Wu, Junyi Li, Sudhir Kumar Baghel, Kapil Gulati, Libin Jiang
