METHOD AND APPARATUS FOR INTERFERENCE CONTROL IN WIRELESS COMMUNICATION SYSTEMS

摘要

Embodiments disclosed herein relate to providing effective interference control in a wireless communication system. In one embodiment, a method for determining an interference level in a wireless communication system is described, including: determining a rise-over-thermal (RoT) metric based on an RoT received at each receiver antenna of an access network, the RoT relating to a ratio of a total energy to a thermal energy received at each receiver antenna; determining an interference-reduction factor (rho) in relation to an interference energy reduced from the total energy received at each receiver antenna; and determining an effective rise-over-thermal (RoT^eff) based on the RoT metric and the interference-reduction factor, the RoT^eff relating to the interference level in the wireless communication system. The method may further include comparing the RoT^eff with a threshold and relating the result of the comparison (e.g., the sector loading status) to each access terminal in communication with the access network.
