Patent number: 10892802Abstract: A method of providing spatial diversity for critical data delivery in a beamformed mmWave small cell is proposed. The proposed spatial diversity scheme offers duplicate or incremental data/signal transmission and reception by using multiple different beams for the same source and destination. The proposed spatial diversity scheme can be combined with other diversity schemes in time, frequency, and code, etc. for the same purpose. In addition, the proposed spatial diversity scheme combines the physical-layer resources associated with the beams with other resources of the same or different protocol layers. By spatial signaling repetition to avoid Radio Link Failure (RLF) and Handover Failure (HOF), mobility robustness can be enhanced. Mission-critical and/or time-critical data delivery can also be achieved without relying on retransmission.Type: GrantFiled: October 7, 2019Date of Patent: January 12, 2021Assignees: Rohm and Haas Electronic Materials LLC, Dow Global Technologies LLCInventors: Lingli Duan, Chen Chen, Shaoguang Feng, Zukhra I.
