This article presents the architecture of MCN toward 3G LTE-Advanced with TDD. On the assumption that L2 RN and L3 RN can provide their own RRM functions, several important RRM functions including routing, link adaptation, and scheduling in MAC layers at RNs can help the eNB to handle the radio resources efficiently. In general, the RN with higher implementation complexity has the ability to provide...
In the 3GPP Long term Evolution system, one of the key techniques to meet the performance requirements in the downlink is the frequency selective schedule (FSS), in which resource allocation and modulation and code schemes are changed adaptively according to the downlink channel quality reported by user equipments (IE). Therefore, the channel quality information (CQI) scheme will directly affect the...
