    摘要： A network device connected to a base station via a backhaul connection may be operable to determine whether the backhaul connection is congested. The determination may be based on a periodic data cap imposed on the backhaul connections. In response to a determination that the backhaul connection is congested, the network device may configure one or more cellular communication parameters of one or more of the plurality of base stations. The determination may be based on one or more of: a total amount of data consumed over the backhaul connection during a current time period, a traffic load on the backhaul connection, and an amount of time remaining in the current time period.

    摘要： A network device may make a determination that a first backhaul connection, which serves a first base station, is congested and that a second backhaul connection, which serves a second base station, is not congested. This determination may be made based on a first periodic data cap imposed (on the first backhaul connection, a traffic load on the first backhaul connection, a second periodic data cap imposed on the second backhaul connection, and a traffic load on the second backhaul connection. In response to the determination, the network device may configure a value of a cellular communication parameter utilized by one or both of the base stations. The configuration may comprise periodic adjustments of the value of the cellular communication parameter. The periodic adjustments may cause one or more mobile devices to be cyclically handed-over between the first base station and the second base station.

    摘要： Certain aspects of the present disclosure provide a technique for bundling the received service data units (SDU) in a first communication layer to generate a protocol data unit (PDU) to pass to a second communication layer. For example, one or more packet data convergence protocol (PDCP) SDUs may be concatenated to generate a PDCP PDU and be sent to a radio link control (RLC) layer in the transmitter side. Similarly, one or more PDCP SDUs may be extracted from a PDCP PDU in the receiver side.

    摘要： An apparatus and method are disclosed for determining the optimal bandwidth fractions for all the users in each frequency band in a wireless communication system to maximize the net sum of user utilities. User utilities are functions of average rates of users, where different averaging rules can be used for different users. The standard approach of computing an optimal scheduler strategy involves the solution of a convex optimization problem that has a complexity on the order of O(N3) for N flows. This approach is not feasible for online implementation having a large number of flows. The method of the present work employs an efficient computational algorithm that obtains the optimal bandwidth fractions in O(N) time. This feature makes the method suitable for implementation in wideband cellular systems like LTE (Long Term Evolution) and UMB (Ultra Mobile Broadband).
