Abstract

In wireless dual-hop decode-and-forward (DF) relaying networks, multiple relay stations (RS) and users construct a DF broadcast channel (DFBC). Due to unpredictable decoding failure, scheduling in the DFBC should depend on not only channel qualities but also the availability of errorless data at individual RSs. Based on the reception qualities of RSs and channel quality information (CQI), we propose a new centralized scheduling scheme to maximize the sum rate of the DFBC. An exact closed-form expression for the sum rate is derived to analyze the new scheme. To further facilitate the analysis, the bounds of the sum rate are derived as a computationally effective alternative to the exact expression. Simulations demonstrate that the derived closed-form expression quantifies the proposed scheduling method accurately. It is also revealed that the analytical bounds are able to characterize the performance of the new scheduling method with acceptable accuracy.
