Wireless networks are becoming increasingly heterogeneous in terms of the processing capabilities of network users' receiving equipment. According to embodiments of the innovation, in a communications network comprising a plurality of receivers with different data reception rate capabilities, data frames targeted to respective receivers may be transmitted to the receivers in accordance with the respective data reception rate capabilities of the receivers.

Real-time rate control mechanism for multi-rate data transmissions in wireless networks

A networked computing system capable of mitigating interference amongst neighboring base stations. The networked computing system includes multiple base stations, user equipment, a network resource controller, and a data communications network facilitating data communications amongst all network devices. A serving base station is configured to acquire interference metrics from its local user equipment and then generate an aggregate representation from the acquired interference metrics. The network resource controller is configured to acquire the aggregate representation, determine an interference reduction associated with a neighbor base station for each of the user equipment serviced by the serving base station, determine a power schedule for the first base station based on the aggregate representation and the determined interference reduction, and then modify a power schedule for the neighbor base station based on the determined interference reduction.

Systems and methods for mitigating intercell interference by coordinated scheduling amongst neighboring cells

Wireless networks are becoming increasingly heterogeneous in terms of the processing capabilities of network users' receiving equipment. According to embodiments of the invention, in a communications network comprising a plurality of receivers with different data reception rate capabilities, data frames targeted to respective receivers may be transmitted to the receivers in accordance with the respective data reception rate capabilities of the receivers.

A method and apparatus provide efficient synchronization recovery at the receiver end for a digital transmission system. At the receiving end, a digital signal is received including a transmitted data portion and a guard period. A signal envelope for the received digital signal is determined, and the signal envelope is filtered to find the center of the guard period, which provides a time reference for the received digital signal. Embodiments of the present invention described herein may be used for optimal operation of a digital transmission system by efficiently recovering synchronization from a received digital signal during noisy conditions without being dependent on signal shape or requiring complicated threshold calculations.
