Future wireless multimedia services require a quality of service guarantee and ubiquitous high data rate for all users. In this paper a scheduling algorithm is proposed for multimedia services in relay-based cellular networks. The decode-and-forwarding relaying protocol with transparent frame structure is used. The scheduling priority takes into account the packet delay and maximum tolerance packet...
An adaptive resource allocation scheme is proposed for regenerative relay-based orthogonal frequency division multiplexing access systems. This scheme allocates subchannels to guarantee fairness between users, and also saves energy by minimising the transmission power. The subchannel allocation for data rate fairness is considered between direct link users and relay stations in the first time subslot...
This paper analyzes the characteristics of time-shifting service for mobile multimedia broadcast and proposes a strategy of resource scheduling for time-shifting proxy server based on predictable user behaviors. Further more, by modeling user behaviors and defining user-habit property, this paper also proposes two different prediction algorithms, the algorithm based on maximum transition probability...
This paper proposes a two-hop proportional fairness scheduling scheme for relay based orthogonal frequency division multiplexing access (OFDMA) systems. The proportional fairness scheduling algorithm is extended to a two-hop scenario to ensure that both direct link users and relay link users are fairly allocated capacity. The fairness allocation problem is considered both in the first time subslot...
