We will present advanced transmission strategies for multimedia traffic over a Multi-Carrier Code Division Multiple Access (MCCDMA) air interface which are both channel- and application aware: in our approach, fluctuations in the channel conditions of different users can be exploited via statistical multiplexing, while application-specific constraints (eg, on the delay of the relevant service) are still considered in the scheduling decision [1]. Furthermore, we apply buffer management at the radio link layer to drop (possibly) outdated packets that are of less importance to the achievable quality [2]. We will demonstrate the performance improvement achievable with our joint system design compared to a purely channel-aware resource allocation strategy for a mixed traffic scenario. The latter consists of parallel H.264 video and background data transmission on the MC-CDMA uplink.

Abstract

We will present advanced transmission strategies for multimedia traffic over a Multi-Carrier Code Division Multiple Access (MCCDMA) air interface which are both channel- and application aware: in our approach, fluctuations in the channel conditions of different users can be exploited via statistical multiplexing, while application-specific constraints (eg, on the delay of the relevant service) are still considered in the scheduling decision [1]. Furthermore, we apply buffer management at the radio link layer to drop (possibly) outdated packets that are of less importance to the achievable quality [2]. We will demonstrate the performance improvement achievable with our joint system design compared to a purely channel-aware resource allocation strategy for a mixed traffic scenario. The latter consists of parallel H.264 video and background data transmission on the MC-CDMA uplink.
