Abstract: A radio access network, such as an LTE E-RAN, employs a hierarchical architecture and includes a services node that provides connectivity between the radio nodes in the RAN and a core network. The RAN employs a hybrid coordinated scheduling scheme in which independent schedulers are running on the services node and the radio nodes. In this way the services node can allocate scheduling resources for some of the UEs in the RAN while the radio nodes can allocate scheduling resources for the remaining UEs in their respective serving cells. In some cases a prioritization approach is used in which the radio nodes do not schedule any radio resources that have already been scheduled by the services node.

Abstract: A base station allocates a radio resource to a scheduling-target user based on a scheduling metric which is calculated for each of scheduling-target users and calculates the amount of available data for each user. When the radio resource is allocated to the scheduling-target user, the amount of data (Dassign) to be communicated using the allocated radio resource is subtracted from the amount of available data (Davailable) for the user. The amount of available data (Davailable) for each user within a cell is updated (min((Davailable+Dref), Dref)) to be less than or equal to a reference data amount in each control period (TAMBR). The scheduling-target user is selected based on the amount of available data for each user.
