LTE (Long Term Evolution) supports QoS (Quality of Service) with several service classes. For each class of traffic, a big difference exists on BER (Bit Error Rate) requirement. This leads to a considerable difference in transmission power for various classes of traffic. In this paper, a novel scheduler is designed and proposed for LTE which supports CoS (Class of Service) with the consideration of...
The relay technology is an essential piece of LTE-Advanced in its pursuit of cost effective capacity enhancement and coverage extension. Simple RF repeaters have been widely used in cellular technologies to offer coverage extension. However, they cannot distinguish desired signals from interference and noise and are unable to operate with sophisticated mechanisms, such as power control, beam-forming,...
The next generation of cellular networks (Long Term Evolution) uses SC-FDMA (Single Carrier Frequency Division Multiple Access) on the uplink. In SC-FDMA, the uplink resources assigned to a user are called Resource Blocks (RBs) each of which consists of a set of consecutive subcarriers spanning all symbols available for data. Since at most one User Equipment (UE) is assigned to each RB then uplink...
