摘要： Systems and methodologies are described that facilitate enhanced resource scheduling for a wireless communication system. As described herein, packets associated with a common flow that arrive within a predetermined time period following a leading packet associated with the flow can be grouped into respective packet bursts. Subsequently, system bandwidth, transmit power, and/or other communication resources can be scheduled based on an analysis of the respective packet bursts. As provided herein, by analyzing respective packet bursts in lieu of individual packets, computational and resource overhead required for resource scheduling can be significantly reduced. In one example described herein, a resource schedule is determined by selecting one or more flows to be assigned bandwidth from among a plurality of flows based on an analysis of packet bursts respectively associated with the flows. Sufficient bandwidth can subsequently be scheduled for the selected flows for transmission of the respectively associated packet bursts.

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).

摘要： A wireless terminal receives and measures broadcast reference signals, e.g., beacon and/or pilot signals, transmitted from a plurality of base station attachment points. The wireless terminal monitors for and attempts to recover broadcast loading factor information corresponding to attachment points. The wireless terminal generates and transmits an interference report to a current attachment point, the report based on the results of a measured received reference signal from the current attachment point, a measured received reference signal from each of one or more different attachment points, and uplink loading factor information. In the absence of a successfully recovered broadcast uplink loading factor corresponding to an attachment point, the wireless terminal uses a default value for that loading factor. Generated interference reports are based on beacon signal measurements and uplink loading factors, pilot signal measureents and uplink loading factors, or a mixture of beacon and pilot signal measurements and uplink loading factors.
