TLDR
The results from the field testbed trial have verified that the proposed backhaul free solution can provide promising capacity gain while squeezing out the need to find a new location to install pico cell base station(s).Abstract:
To satisfy the fast growing throughput requirement in certain hot spot areas, pico cells are suggested to be deployed within the Macro cell coverage, forming a heterogeneous network (HetNet). However, it is difficult to deploy new sites in dense populated urban cities for new deployment and new fiber for the corresponding backhaul requirement. To solve these problems, a new architecture is proposed in this paper that a pico cell can be formed via a special antenna collocated with macro base station. With this backhaul free virtual HetNet (vHetNet) architecture, it is easy to realize CoMP and/or joint processing between the macro cells and picocells. The joint data transmission and control information transmission in such vHetNet is also discussed. The results from the field testbed trial have verified that the proposed backhaul free solution can provide promising capacity gain while squeezing out the need to find a new location to install pico cell base station(s).read more

Method and node in a wireless communication network
TL;DR: In this paper, the authors propose a mutually orthogonal pilot sequence to each UE (220-1, 220-2, 220 3, 220 4, 220 5, 220 6, 220 7, 220 803) and assign a resource offset to the UEs in each UE group (260, 270, 270), by which each UE is allowed to start its transmission subframe in its Transmission Time Interval, TTI.

TL;DR: The need for an alternative strategy, where low power nodes are overlaid within a macro network, creating what is referred to as a heterogeneous network is discussed, and a high-level overview of the 3GPP LTE air interface, network nodes, and spectrum allocation options is provided, along with the enabling mechanisms.

A methodology for estimating cost and performance of heterogeneous wireless access networks
TL;DR: In this article, the authors proposed a methodology for analyzing the total cost and performance of heterogeneous wireless access networks, composed of multiple base station classes and radio access technologies with different cost and technical characteristics, and demonstrated how the methodology can be applied for different combinations of cellular and wireless local area network systems.
