Downlink Carrier Aggregation is a promising LTE-Advanced technology which is introduced in 3GPP LTE Release 10. Meanwhile, it introduces some challenges since more uplink control information needs to be fed backed from UE to eNB to enable the carrier aggregation. In this paper, we firstly introduce the CA feature in LTE-Advanced, and present the PUCCH format 1b with channel selection and PUCCH format...
The continuing advances in the storage and transmission abilities of user equipment have made it possible to share videos through device-to-device communications, which may be an efficient way to enhance the capacity of cellular network to provide wireless video services. In adaptive D2D video streaming, user experience is greatly influenced by the quality and fluency of the video, which is affected...
Mobile WiMAX's scheduling service is a key factor in Radio Resource Management (RRM) in realizing Quality of Service (QoS). The choice in scheduling algorithm for Mobile WiMAX base stations, albeit outside of the scope of the standard, critically impacts the performance and robustness of Mobile WiMAX networks. This paper provides an in-depth study of four major scheduling algorithms: Round Robin (RR),...
