Abstract

An apparatus, system and method for providing interference cancellation and communication resource reservation limits to allocate communication resources in a communication system. In one embodiment, the apparatus includes a processor (1320) and memory (1350) including computer program code. The memory (1350) and the computer program code are configured, with the processor (1320), to cause the apparatus to identify an interval of received signal power levels for interference cancellation of an interfering signal to a primary signal, and generate a message that provides the interval of received signal power levels for the interference cancellation of the interfering signal to the primary signal. In a related embodiment, the memory (1350) and the computer program code are configured, with the processor (1320), to cause the apparatus to determine a communication resource reservation limit, and request an increase in the communication resource reservation limit.
