By separately transmitting data and control signals from different tiers, dual connectivity (DC) delivers a potential solution to the handover and load balancing challenges brought by small cell deployment. In this paper, a tractable framework is developed for the downlink performance analysis of DC assisted heterogeneous cellular networks (HetNets). Based on a stochastic geometry model, accurate...
Small cell networks as an important evolution path for the next generation cellular networks, have drawn much attention. Different from traditional base stations (BSs) always-on model, we proposed a BSs on-off model where a new simple expression of the BS active probability of HetNet is derived. This model is more suitable for the practical network where BSs are not always-on. Based on this, we develop...
Power consumption and costs of the analog front-end (AFE) chains are often not negligible for large-scale antenna array systems. A low-complexity hardware architecture is to use a number of AFE chains that is less than the number of the antennas. Beamforming for this low-complexity hardware architecture involves both digital and analog beamforming, which is termed hybrid analog/digital beamforming...
This paper investigates the transmission capacity of the secondary network in overlaid ad hoc networks with multi-antenna spatial multiplexing. Based on stochastic geometry tools, we study the effects of the node density and the transmission power of the secondary network on the transmission capacity performance. We derive the optimal node density for the secondary network, and subsequently the optimal...
In practical use, data traffic has a feature of high-burst in wireless network, which means that the serve request of a user is not continuous. With full buffer traffic model, network operators can give evaluations on the peak data rate and the least data rate of heavy load network. However, rather than the peak data rate and the least data rate, what attracts users most may sometimes be the typical...
