CPC H04L 5/0092 (2013.01) [H04L 5/0096 (2013.01); H04W 24/08 (2013.01); H04W 28/0221 (2013.01); H04W 48/18 (2013.01)] | 20 Claims |
1. A system for adaptive bandwidth (BW) control in a 5G wireless network, the system comprising:
a network control system configured to monitor at least one of power and traffic loads at a plurality of nodes in the 5G wireless network, wherein each of the plurality of nodes provides a set of network slices each comprising one or more initial bandwidth parts (BWPs) for communicating with user equipment (UE) via the 5G wireless network; and
a BW controller communicating with the network control system, wherein the BW controller is configured to:
receive a notification from the network control system indicating a change of state at one of the plurality of nodes;
in response to the notification indicating the change of state, initiate a process by the node to automatically move at least some of the UE communicating with the node from the initial BWPs to at least one lower BWP supported by the node, the at least one lower BWP having a lower bandwidth than the initial BWPs;
after moving the at least some of the UE communicating with the node to the at least one lower BWP, power down at least some of the initial BWPs to thereby reduce power consumption by the node; and
in response to a subsequent notification from the network control system indicating that the change of state has subsided, initiate a restoration process by the node to restore the initial BWPs and to move the at least some of the UE from the at least one lower BWP to the initial BWPs.
