Abstract :
This paper compares the user throughput and the sector throughput performance using fast sector selection (FSS) with muting and simultaneous transmission with soft-combining for the intra-node B macro diversity in the downlink OFDM based radio access. System-level simulations show that FSS with muting achieves an approximately 10% higher user throughput for intra-node B macro diversity user equipment (UE) compared to simultaneous transmission with soft-combining, while maintaining almost the same user throughput performance for one-link connection UE assuming the equal served traffic model. Therefore, we conclude that FSS with muting is a more promising candidate than simultaneous transmission with soft-combining as the intra-node B macro diversity scheme in the downlink OFDM based radio access
