Patent number: 11463154Abstract: An active repeater device includes a primary sector and one or more secondary sectors, receives a first beam of input RF signals. A first set of analog baseband signals, are generated based on received first beam of input RF signals. The first set of analog baseband signals are converted to a first set of coded data signals and control information is extracted from the first set of coded data signals by decoding only a header portion of the first set of coded data signals without demodulation of data portion of the first set of coded data signals. Based on the extracted control information, the first set of coded data signals are transmitted as beams of output RF signals to remote user equipment. The transmission is independent of demodulation of the data portion within the active repeater device to reduce latency for transmission of the first set of coded data signals.Type: GrantFiled: February 9, 2021Date of Patent: October 4, 2022Assignee: Movandi CorporationInventors: Sam Gharavi, Ahmadreza Rofougaran, Michael Boers, Seunghwan Yoon, Kartik Sridharan, Donghyup Shin, Farid Shirinfar, Stephen Wu, Maryam Rofougaran
