Abstract:
Methods and apparatus are provided for receiving a serving signal from a base station by a user equipment. A signal that includes the serving signal and an interference signal is received. A Log Likelihood Ratio (LLR) of the received signal is calculated according to each of a plurality of modulation orders applicable to the interference signal to obtain a plurality of LLR values. A modulation order of the interference signal is determined, based on the plurality of LLR values. The serving signal is reconstructed, based on the determined modulation order.
