First Claim
Patent Images
1. A method of controlling radio resources in a radio network, comprising:
- receiving an uplink signal from a user using the network;
performing interference cancellation to the uplink signal;
estimating a load factor on the uplink signal, the load factor indicating a load the uplink signal causes on the network, wherein the load factor is estimated by taking into consideration the interference cancellation performed on the uplink signal; and
allocating radio resources in the network by using the load factor.
