Research on smart antenna has been incorporated in the evolution path from TD-SCDMA to TD-LTE. To reduce the array size of the mono-polarized smart antenna in TD-SCDMA systems, dual-polarization scheme is considered to facilitate the application of smart antenna in TD-LTE systems. In this paper, we investigate the performance degradation due to dual-polarization for smart antenna in TD-LTE system...
TD-LTE as the evolution of TD-SCDMA is designed to support high data rates and reduced radio link delays. To reach these goals, new air interface is specified for TD-LTE. In this paper, the performance of physical uplink and downlink channels are evaluated by means of numerical simulations. Since the deployment of smart antennas is the unique feature of TD-SCDMA, special attentions are paid to the...
In order to mitigate the error propagation and achieve diversity gain, an enhanced distributed turbo coding (DTC) with soft information relaying (SIR) scheme is proposed for relay systems in practical fading channels. For the proposed scheme, not only the soft information of the additional parity bits but also the soft information of the systematic bits are regenerated and repeated at the relay. To...
Relaying is expected to be one key element of the future cellular networks. This paper focuses on 3GPP LTE-Advanced network incorporated with Type I relay nodes. We first present the required radio resource management (RRM) framework which includes routing, resource partition and scheduling functions. Then two RRM strategies are suggested: one with the conventional cellular settings, the other with...
