Patent number: 10764959Abstract: Two algorithms for different functional-split network models are provided, which are the CU-based (central unit based) beam allocation and admission control algorithm (CU-BAACA) and the DU-based (distributed unit based) beam allocation and admission control algorithm (DU-BAACA). Difference between the CU-BAACA and DU-BAACA includes whether the algorithm is implemented at the CU site or at the DU site. Proposed algorithms aim to optimize DUs' quality of experience (QoE) by admission control to determine the amount of data from application layer entering into traffic queue and allocating beam in physical layer at the fronthaul network between CU and DUs. On the other hand, queueing delay and queue stability are taken into consideration to maintain the system steadiness. Simulation results compare performance of two functional split models to find the appropriate scenario for each function split option, which provide technical requirement and applicability of the proposed algorithms for practical system.Type: GrantFiled: January 28, 2019Date of Patent: September 1, 2020Assignee: NATIONAL CHIAO TUNG UNIVERSITYInventors: Kai-Ten Feng, Tun-Ping Huang, Chun-Hao Fang, Pei-Rong Li

Patent number: 8705464Abstract: Exemplary embodiments of the present disclosure provide several packet scheduling methods and communication apparatuses using the same. The packet scheduling method is different from the conventional packet scheduling method, since it does not schedule the sleep interval of the mobile subscriber station based upon the connections as the conventional packet scheduling method. Instead, the packet scheduling method considers the quality of service, and aggregates the data bursts to the frame corresponding to the frame index to which the data bursts are shifted based upon the individual packet, such that a total time length of the sleep intervals of the mobile subscriber station is maximized, and the maximum power saving efficiency is obtained correspondingly.Type: GrantFiled: July 19, 2010Date of Patent: April 22, 2014Assignee: Universal Scientific Industrial (Shanghai) Co., Ltd.Inventors: Wen-Jiunn Liu, Kai-Ten Feng
