Method and base station for handling radio resources

摘要

A method and a base station configured to serve a first cell in a cellular network, for supporting radio resource management in the cellular network. When receiving an indication of uplink interference experienced in a neighboring second cell, the base station identifies interfered bandwidth resources on which the interference is experienced, and detects that these resources coincide with resources that have been allocated to User Equipments, UEs, in the first cell. When the interfered bandwidth resources coincide with resources that have been allocated to cell edge UEs in the first cell, the base station allocates bandwidth resources separate from the interfered resources to the cell edge UEs. Further, when the interfered bandwidth resources coincide with resources allocated to cell center UEs in the cell, the base station applies power control for transmissions made by the cell center UEs on the interfered resources.

1. A method in a base station serving a first cell in a cellular network, for supporting radio resource management in the cellular network, the method comprising:
receiving an indication of uplink interference experienced in a neighbouring second cell, identifying interfered bandwidth resources on which said uplink interference is experienced in the neighbouring second cell based on the received indication of uplink interference, detecting that the interfered bandwidth resources coincide with bandwidth resources that have been allocated to User Equipments (UEs) in the first cell, when the interfered bandwidth resources coincide with bandwidth resources that have been allocated to cell edge UEs in the first cell, allocating bandwidth resources separate from the interfered bandwidth resources to the cell edge UEs, and when the interfered bandwidth resources coincide with bandwidth resources that have been allocated to cell centre UEs in the first cell, applying power control for uplink transmissions made by the cell centre UEs on the interfered bandwidth resources; wherein the bandwidth resources comprise Physical Resource Blocks (PRBs) defined by frequency and time interval.
