“…Thus, there are four possible sets of transmitting antenna weights and one of these sets is chosen based on the UE feedback information. More information about phase adjustment and also comparison of HS-SFN with and without phase adjustment can be found in [15].…”

High Speed Single Frequency Network (HS-SFN) is a multicell transmission scheme for High-Speed Downlink Packet Access (HSDPA) that can assist user equipment (UEs) in the softer handover area by combining signals from two neighbouring cells and at the same time by reducing the inter-cell interference. This article analyzes performance of HS-SFN for macro cell scenario under different channels with different type of schedulers by means of extensive system level simulations. The results indicate that HS-SFN can increase throughput for UEs in softer handover area from 40% to 80% without decreasing the overall performance.

“…As its name suggests, transmissions are performed synchronously so that the signals are combined and seen as a single multipath signal at the UE receiver [5]. We focus in this paper on this coordination scheme as its performance evaluation has been rarely addressed in the literature.…”

Abstract-High Speed-Single Frequency Network (HS-SFN) is one of the possible multipoint transmission techniques proposed in the 3GPP standard for High Speed Downlink Packet Access (HSDPA) in order to improve network performance, especially at the cell edge. It allows neighboring cells to transmit simultaneously the same data stream to a User Equipment (UE) in the Handover region (HO). In order to evaluate the user-level performance of this technique, we develop a method based on network simulation coupled with Markov chain analysis. It shows that when the HS-SFN technique is performed in the HO region between adjacent cells, the user data rates increase significantly. However, this is true only when involved cells are partially loaded, which is not always the case. We thus propose an optimized approach that adapts the coordination area based on the average offered traffic observed in the network. Network performance is then improved at any load.
