Abstract
One embodiment is directed to off-loading at least some of the baseband processing for signals received at or transmitted by at least one overloaded radio point to at least one other radio point so that the off-loaded baseband processing is performed by the at least one other radio point. The radio points are a part of a centralized or cloud radio access network (C-RAN) or similar system.
Claims50
A system to provide wireless service comprising:
- at least one controller;
- and
- a plurality of radio points;
- wherein each of the radio points is associated with at least one antenna and remotely located from the controller, wherein the plurality of radio points is communicatively coupled to the controller;
- wherein the controller and the plurality of radio points are configured to implement at least one base station in order to provide wireless service to a plurality of user equipment (UEs) using at least one cell;
- wherein the controller is communicatively coupled to a core network of a wireless service provider;
- wherein the controller is configured to:
- determine, for a scheduling interval, an initial resource allocation to one or more UEs for one or more wireless channels used to serve said at least one cell;
- determine, for the initial resource allocation, initial baseband processing loads for performing baseband processing for signals received at or transmitted by the radio points serving said at least one cell;
- identify one or more radio points that are overloaded for said scheduling interval based on the initial baseband processing loads;
- and
- off-load at least some of the baseband processing for signals received at or transmitted by at least one overloaded radio point to at least one other radio point so that the off-loaded baseband processing is performed by said at least one other radio point.
A method of load balancing baseband processing in a wireless system comprising at least one controller and a plurality of radio points, wherein each of the radio points is associated with at least one antenna and remotely located from the controller, wherein the plurality of radio points is communicatively coupled to the controller, wherein the controller and the plurality of radio points are configured to implement at least one base station in order to provide wireless service to a plurality of user equipment (UEs) using at least one cell, wherein the controller is communicatively coupled to a core network of a wireless service provider, the method comprising:
- determining, for a scheduling interval, an initial resource allocation to one or more UEs for one or more wireless channels used to serve said at least one cell;
- determining, for the initial resource allocation, initial baseband processing loads for performing baseband processing for signals received at or transmitted by the radio points serving said at least one cell;
- identifying one or more radio points that are overloaded for said scheduling interval based on the initial baseband processing loads;
- and
- off-loading at least some of the baseband processing for signals received at or transmitted by at least one overloaded radio point to at least one other radio point so that the off-loaded baseband processing is performed by said at least one other radio point.
