Patent ID: 10243683

Abstract:
A technique for cancelling interference in a cellular network (100) is provided. The cellular network (100) comprises intra-frequency cells (102, 104, 106) sending a first identifying signal indicative of a first identifier (ID1) and a second identifying signal indicative of a second identifier (ID2). Each of the cells is identified by a combination of the first identifier and the second identifier. As to a method aspect of the technique, first samples of the first identifying signal are extracted from a signal received by a User Equipment (120). The first samples include contributions from different cells (104, 106) of the cellular network (100). A first set of sample points is selected based on the first samples and a first candidate (104-1) for the first identifier (ID1). Second samples of the second identifying signal are extracted from the received signal. The second sample includes contributions from the different cells (104, 106). A second set of sample points is selected based on the second samples and a second candidate (104-2) for the second identifier (ID2). The interference of the first identifying signal and/or the second identifying signal is cancelled from the received signal based on both the first set and the second set.
