Method and base station for controlling interference

摘要

A method and base station (600) of a first cell (602), for—controlling inter-cell interference in a cellular network when Discontinuous Reception, DRX, is applied for User Equipments, UEs. The base station selects a DRX scheme with active periods that are separated in time from active periods of a DRX scheme used for UEs in DRX mode in a neighboring second cell (806). The selected DRX scheme is then used for a first UE (604) in DRX mode in the first cell to avoid interference between transmissions of signals in the active periods to the first UE in the first cell and transmissions of signals in active periods to the UEs in the neighboring second cell.

1. A method in a base station serving a first cell in a cellular network, for controlling inter-cell interference in the cellular network when Discontinuous Reception, DRX, is applied for User Equipments, UEs, in the cellular network, the method comprising:
selecting a DRX scheme with active periods that are separated in time from active periods of a DRX scheme used for UEs in DRX mode in a neighbouring second cell, and using the selected DRX scheme for a first UE in DRX mode in the first cell to avoid interference between transmissions of signals in active periods to the first UE in the first cell and transmissions of signals in active periods to the UEs in the neighbouring second cell.
