Abstract
A Physical Broadcast Channel (PBCH) Interference Cancellation (PBCH-IC) solution is presented herein. The PBCH-IC provides accurate and efficient techniques for cancelling interference from a serving cell PBCH. In one embodiment, PBCH symbols previously determined for an aggressor cell are canceled from a PBCH sequence currently received by the wireless device to produce a serving cell PBCH free of interference. In another embodiment, the PBCH symbols of the aggressor cell are reconstructed in the frequency domain and converted to the time domain to generate an aggressor PBCH sequence. The aggressor PBCH sequence is then subtracted from the received PBCH sequence to cancel the aggressor cell interference.
