Balancing Uplink and Downlink under Asymmetric Traffic Environments Using Distributed Receive Antennas
Recently, multimedia services are increasing with the widespread use of various wireless applications such as web browsers, real-time video, and interactive games, which results in traffic asymmetry between the uplink and downlink. Hence, time division duplex (TDD) systems which provide advantages in efficient bandwidth utilization under asymmetric traffic environments have become one of the mo...
متن کاملSpectral Efficiency of Time Division Duplex Fixed Wireless Cellular System for Dynamic Traffic
We analyze spectral efficiency of a dynamic time division duplex system in a fixed wireless cellular network. Conventionally, spectral efficiency has been analyzed under static and fully-loaded conditions. In this paper, we investigate how asymmetric and dynamic traffic affects spectral efficiency of TDD systems. Recently, dynamic TDD (D-TDD) has gained much attention as an efficient duplex sch...
متن کاملRegion-Based Decentralized Time Slot Allocation Strategy for Asymmetric Traffic in TDD Systems
Time division duplex (TDD) systems and their crossed-slot interference problem in cellular environment have been attracting increasing interest. To mitigate the crossed-slot interference, we propose the REgion-based Decentralized Time Slot Allocation (RED-TSA) strategy, and evaluate its call blocking probability, uplink SINR, and overall uplink throughput compared with those of previous TSA str...
متن کاملDynamic resource allocation for CDMA-TDD indoor wireless systems
Future wireless communication systems are expected to provide a broad range of multimedia services that have a significant traffic asymmetry between uplink and downlink. The code division multiple access time division duplex (CDMA-TDD) system is a promising solution to cope with the problem of traffic asymmetry. However, the TDD system is subject to inter-cell interference compared to frequency...
متن کاملAdaptive Slot Management for Ofdma Based Cellular Wireless Networks in Tdd Mode
The next generation of mobile networks is expected to support real-time multimedia applications with different classes of traffic and diverse bandwidth requirements. The Orthogonal Frequency Division Multiple Access (OFDMA) system with time division duplex mode, employing asymmetric slot allocation between uplink and downlink, is a good solution for mixed realistic traffic. In this paper, we in...
