Patent number: 11627473Abstract: A method for determining a layout of a wireless communication network is provided in the present invention. Numerous realizations of user device placement in a considered geometry are measured to reflect the practical distribution of the user devices in a more accurate way than the conventional approach which emulates the randomness of placements of user devices using a tractable stochastic process. Moreover, a scenario sampling approach is used to provide a lower-complexity and higher efficient way to yield optimal base station deployment results while guaranteeing the quality of service of a specified majority of the overall user device realizations.Type: GrantFiled: July 5, 2021Date of Patent: April 11, 2023Assignee: City University of Hong KongInventors: Miaomiao Dong, Jingjin Timothy Wu, Wing-Ming Eric Wong

Patent number: 11304062Abstract: A system and method for determining a layout of a wireless communication network in a terrain. The wireless communication network includes multiple wireless communication devices each arranged to communicate wirelessly with one or more external communication devices. The method includes obtaining a modelled terrain of the terrain in which the wireless communication devices of the wireless communication network can be arranged. The modelled terrain includes a first type of area in which external communication devices can be located, and a second type of area representing obstacles arranged to affect communication between the wireless communication devices and the external communication device. The method also includes determining, based on a criteria, respective installation locations of the wireless communication devices in the modelled terrain so as to determine a layout of the wireless communication network in the terrain.Type: GrantFiled: May 21, 2020Date of Patent: April 12, 2022Assignee: City University of Hong KongInventors: Jianqing Liu, Wing Ming Eric Wong

Patent number: 10645646Abstract: A communication system and method for operating or evaluating the communication system includes powering a plurality of base stations each operating in at least a sleep mode and an active mode, wherein the base station operates in the sleep mode with less power consumption than in the active mode; analyzing an overall power consumption for powering the plurality of base stations with respect to a grade of service of the communication system; and switching at least one of the plurality of base stations to operate between the sleep mode and the active mode based on a result associated with the overall power consumption and/or the grade of service. Each of the plurality of base stations in sleep mode is further arranged to pass a service request to a nearby base station in the plurality of base stations such that the service request is handled by the respective nearby base station.Type: GrantFiled: January 11, 2018Date of Patent: May 5, 2020Assignee: CITY UNIVERSITY OF HONG KONGInventors: Jingjin Timothy Wu, Wing Ming Eric Wong, Moshe Zukerman, Jun Guo

Publication number: 20190206550Abstract: A method for managing admission of patients into one of a plurality of intensive care units in a hospital network includes classifying a patient arriving at a first intensive care unit as one of an external emergency patient, an internal emergency patient, and an elective patient; and determining whether to admit the patient to the intensive care units in the hospital network based on the classification. An external emergency patient is admitted to the first intensive care unit if a vacancy in the first intensive care unit is above a first threshold. An internal emergency patient is admitted to the first intensive care unit if the first intensive care unit has vacancy. An elective patient is admitted to the first intensive care unit if a vacancy in the first intensive care unit is above a second threshold. The first and second thresholds are independent of patient classification.Type: ApplicationFiled: January 2, 2018Publication date: July 4, 2019Inventors: Wing Ming Eric Wong, Yin Chi Chan, Gavin Joynt, Moshe Zukerman
