Heterogeneous Link Asymmetry in Tdd Mode Cellular Systems

چکیده

Time Division Duplex systems provide great flexibility that can be used to implement asymmetrical links. Adverse interference conditions easily arise, however. Especially if different asymmetries are required in neighbouring cells. This paper assesses the performance of TDD mode systems in evironments that require heterogeneous link asymmetry. In particular the Soft Switching Point and Disjoint Base station Set algorithms are considered. Results indicate that gradual asymmetry variations can be handled with almost no performance loss, but random variations result in capacity loss.

Enhancing massive MIMO: A new approach for Uplink training based on heterogeneous coherence time

Massive MIMO is one of the key technologies in future generation networks. Owing to their considerable spectral and energy efficiency gain, massive MIMO systems provide the needed performance to cope with the ever increasing wireless capacity demand. Nevertheless, the number of scheduled users stays limited in massive MIMO systems both in TDD and FDD modes. This is due to the limited time slot ...

Performance Analysis of Joint Adaptive Modulation and Diversity Combining in TDD-CDMA Systems

Adaptive modulation and diversity combining represents the enabling techniques for the future generation of wireless communication. Adaptive modulation is a transmission scheme in digital communications where the transmitter adapts its transmission mode in accordance with the channel. In TDD systems the channel state is known in the transmitter side because of channel reciprocity, hence the ada...

Dynamic 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...

Downlink power control of dedicated channels in UTRA TDD

This paper discusses downlink power control of dedicated channels in UTRA TDD. The current UTRA TDD downlink power control is similar to the one in UTRA FDD mode, that comprises of closed inner loop and quality based outer loop. However, due to the time division feature and associated flexibility with asymmetry of TDD, the inner loop can not operate as fast as in FDD and it is affected by rapid...

Interference analysis of and dynamic channel assignment algorithms in TD–CDMA/TDD systems

The radio frequency spectrum for commercial wireless communications has become an expensive commodity. Consequently, radio access techniques are required which enable the efficient exploitation of these resources. This, however, is a difficult task due to an increasing diversity of wireless services. Hence, in order to achieve acceptable spectrum efficiency a flexible air– interface is required...
