An incremental scheduling scheme is proposed in a wireless communication system with beamforming. In an initial stage (stage-1), coarse scheduling plan is granted via control beam transmission. In a second stage (stage-2), fine scheduling plan is granted via dedicated beam transmission. Such incremental scheduling scheme provides load balancing for overhead channels on control/dedicated beams via stage-2 scheduling. It utilizes dedicated beam transmission that is more resource efficient and more UE-specific. Furthermore, it provides UE natural power-saving opportunities via stage-1 scheduling.

The two forces used are gravity and the atmospheric pressure. Gravity initiates the power phase by causing the water to fall from the elevated sealed water tank 10 to turn the turbine 32. The water lowers to 33.95 feet above ground level within the sealed water tank 10. A vacuum forms above the water. The water flows from the turbine into the elevated open water tank 46 to the level whereby its water outlet valve 26B opens. This affords a passage back into the elevated sealed water tank 10, through the check valve 40 and the manual shut-off valve 42. This initiates the recovery phase. The atmospheric pressure of 14.7 psi on the elevated open water tank 46 forces the water back into the sealed water tank 10 to relieve the vacuum. This pressure is capable to move the water up to 33.95 feet. Here it has only to move it up to 26.95 feet, realizing a 20.6 percent reserve force. With the water level again attaining maximum height in the sealed water tank 10, it is again released to repeat the cycle.
