  • Patent number: 10764959
    Abstract: 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.

  • Patent number: 9332471
    Abstract: Network device selection or handover schemes enable higher network capacity based on partially-observable Markov decision processes. Unavailable cell loading information is observed and/or predicted from non-serving base stations and actions are taken to maintain an active base station set or network device candidate data for selection in routing communications of a mobile device in a mobile device cell selection or handover procedure. A reward function is considered in the selection based on various parameters comprising system capacity, handover times, and mobility of a mobile device or mobile station.

  • Patent number: 8958819
    Abstract: The disclosed subject matter relates to a wireless communications environment. Femto-assisted location estimation schemes can determine UE location information based on information from either macro base stations or femto base stations in a LTE-A heterogeneous network. Positions information for a femto base station can be employed even though the exact positions of fBS may not be available. The femto base station position information can be depicted as a probabilistic distribution. Bayesian estimation based on TDOA and utilization of a particle filter can facilitate determining UE location information. Furthermore, a simplified scheme can reduce computational complexity.

  • Patent number: 8705464
    Abstract: 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.
