Radio resource management for uplink carrier aggregation in lte- advanced hua wang1*, claudio rosa2 and klaus i pedersen1, 2 abstract this paper investigates the uplink resource allocation prob lem in the context of long- term evolution ( lte) - advanced systems with carrier aggregation ( ca) and dual - cluster scheduling. This practical hands- on new resource presents radio resource management in lte advanced book lte technologies from end- to- radio resource management in lte advanced book end, including network planning radio resource management in lte advanced book and the optimization tradeoff radio resource management in lte advanced book process. This book examines the features of lte- advanced and lte- advanced pro and how they integrate into existing lte networks. Key technologies presented include multi- carrier transmission, advanced single- carrier transmission, advanced receivers, ofdm, mimo and adaptive antenna solutions, advanced radio resource management and protocols, and different radio network architectures. Their role and use in the context of mobile broadband access in general is explained. Carrier aggregation ( ca) is one of the key features for long- term evolution ( lte) - advanced to support higher transmission bandwidth up to 100 mhz, enabling peak date radio resource management in lte advanced book rates requirements of up to 1 gbps in downlink and 500 mbps in uplink radio resource management in lte advanced book to be satisfied. With the massiﬁcation of long term evolution ( lte) networks and their growing usage among all mobile users, the necessity to efﬁciently manage the available radio resources becomes more and more essen- tial, in order to maintain quality of service ( qos) levels while radio resource management in lte advanced book sustaining economic viability. Radio resource management attracts great attention while utilizing radio resource management in lte advanced book available resources to provide radio resource management in lte advanced book users with enhanced system throughput.
Radio resources management include transmission power management, mobility management, and scheduling of radio resources. An intelligent radio resource management is at the heart of lte to. No work in the literature on radio resource allocation for lte- advanced cellular networks with m2m communications so far. The scope of this article is hence to examine how h2h users and mtc devices can share available radio resources efﬁciently so as to mitigate co- channel interference and thus enhance network efﬁciency.
