Systems and methods for downlink power control and scheduling in a wireless network

摘要

Methods and systems for providing joint power control (PC) and scheduling in a wireless network are provided. In one example, a method includes generating a near-optimal power pattern for PC and scheduling in accordance with long term channel statistics. The near-optimal PC solution may be generated by first generating a set of possible power patterns in accordance with likely scheduling scenarios, then statistically narrowing the set of possible power patterns to identify the most commonly used power patterns, and finally selecting one of the most commonly used power patterns as the near-optimal power pattern. In another example, a table of optimal PC solutions are provided for performing distributed PC and scheduling in an adaptive and/or dynamic manner.

1. A method for joint power control (PC) and scheduling in a wireless network, the method comprising:
receiving, by a controller, channel statistics corresponding to downlink channels associated with a plurality of base stations, wherein the channel statistics are collected during a first instance of a periodic time interval; generating a set of possible power patterns in accordance with the channel statistics; and selecting one or more power patterns from the set of possible power patterns, wherein the one or more selected power patterns are used to schedule resources for the plurality of base stations during a second instance of the periodic time interval.
