Method and base station of adjusting uplink load variance due to uplink beam direction change
The present invention provides a method of adjusting uplink load variance due to a change of a beam direction turning from towards a current beamforming control cell to towards a target beamforming control cell, comprising: estimating an uplink load increment of the target beamforming control cell due to the change of the beam direction, before the beam direction turning from towards the current beamforming control cell to towards the target beamforming control cell; comparing the estimated uplink load increment with an available uplink load headroom of the target beamforming control cell; and adjusting an uplink load grant of a user equipment if the uplink load increment is larger than the available uplink load headroom, so that an uplink load increment is not beyond the available uplink load headroom, so that the uplink load increment is not beyond the available uplink load headroom.
