Schedulers that allocate resource grants on a slot-by-slot basis within a scheduling epoch or frame can create a front-loading effect where allocations occur more frequently in slots earlier in frames. To address these and other issues, systems and methods are disclosed for scheduling resource grants in a network to improve network transmit power profiles. For example, a scheduler is configured to randomize the order of slots in a scheduling epoch or frame, with different randomizations for different schedulers, to more evenly distribute slots with resource grant allocations to prevent or reduce a front-loading effect. As another example, the scheduler is configured to randomize start times of resource blocks within a slot to prevent or reduce the front-loading effect.

Improving network transmit power profile by randomizing resource grants on a multi-user communications network

Systems and methods are described that enable user terminals to eliminate or reduce the number of dummy bursts (or bursts with no data) they send. The systems and methods use two burst detectors, a first burst detector that analyzes the physical structure of the signal, and a second burst detector that analyzes the informational structure of the signal. Output from the first burst detector can be used to control operation of a signal decoder that decodes received signals. The second burst detector analyzes output from the signal decoder to determine the second burst indicator. In other words, the first burst detector can be implemented prior to decoding the received signal to provide a first estimate related to the presence or absence of a burst. This can then be used to limit the amount of processing performed by the signal decoder.
