Samsung patents method for cell towers to avoid signal clashes

1. A method performed by a first base station for controlling collision of shared resources in a communication system, the method comprising: receiving, from a second base station, a resource sharing message including information on the shared resources, wherein a priority of the second base station is higher than a priority of the first base station, for using the shared resources; performing a communication with a first terminal using the shared resources; receiving, from the second base station, a collision control message including information on a failure resource where data transmission between a second terminal and the second base station has failed, the information on the failure resource including a location of the failure resource in a time domain or a frequency domain; identifying a collision rate based on a number of collision resources within a predetermined resource region, using the information on the failure resource; and performing scheduling for the first terminal to restrict usage of at least one resource among the shared resources, in case that the collision rate is higher than a predetermined collision rate, wherein the at least one resource is determined based on a size of the predetermined resource region, the number of collision resources, and the predetermined collision rate.
