Abstract: This very up-to-date and practical book, written by engineers working closely in 3GPP, gives insight into the newest technologies and standards adopted by 3GPP, with detailed explanations of the specific solutions chosen and their implementation in HSPA and LTE. The key technologies presented include multi-carrier transmission, advanced single-carrier transmission, advanced receivers, OFDM, MIMO and adaptive antenna solutions, advanced radio resource management and protocols, and different radio network architectures. Their role and use in the context of mobile broadband access in general is explained. Both a high-level overview and more detailed step-by-step explanations of HSPA and LTE implementation are given. An overview of other related systems such as TD SCDMA, CDMA2000, and WIMAX is also provided.This is a 'must-have' resource for engineers and other professionals working with cellular or wireless broadband technologies who need to know how to utilize the new technology to stay ahead of the competition.The authors of the book all work at Ericsson Research and are deeply involved in 3G development and standardisation since the early days of 3G research. They are leading experts in the field and are today still actively contributing to the standardisation of both HSPA and LTE within 3GPP. * Gives the first explanation of the radio access technologies and key international standards for moving to the next stage of 3G evolution: fully operational mobile broadband* Describes the new technologies selected by the 3GPP to realise High Speed Packet Access (HSPA) and Long Term Evolution (LTE) for mobile broadband * Gives both higher-level overviews and detailed explanations of HSPA and LTE as specified by 3GPP

TL;DR: A hybrid division cooperative transmission (HDCT) scheme for system throughput enhancement in enterprise femtocell systems achieves an improved signal to interference plus noise ratio (SINR) by using two time synchronized signals from two adjacent fBSs.
Abstract: In this paper, we propose a hybrid division cooperative transmission (HDCT) scheme for system throughput enhancement in enterprise femtocell systems. In HDCT scheme, a cooperative transmission (CT) scheme is applied to user equipments (UEs) located at the edge of a serving femtocell base station (fBS), whereas conventional scheme is applied to UEs located near the fBS. In the zone where CT is applied, a UE is capable of receiving desired signal from serving fBS as well as from an adjacent fBS. Thus, the UE achieves an improved signal to interference plus noise ratio (SINR) by using two time synchronized signals from two adjacent fBSs. Performance of the proposed scheme is evaluated in terms of call level quality of service (QoS) (i.e., call blocking probability) and packet level QoS (i.e., outage probability). We first measure the resource utilization and call blocking probability for the downlink channel for various offered load. Based on that, we obtain the outage probability and effective throughput of the system by computer simulations. Finally, the results of the simulation yield the optimum hybrid zone for achieving the maximum system throughput.

TL;DR: An improved detector for ACK/NACK message detection in the LTE uplink control channel with imperfect channel state information at the receiver based on the generalized likelihood-ratio test (GLRT) paradigm is presented.
Abstract: In this paper, we present an improved detector for ACK/NACK message detection in the LTE uplink control channel with imperfect channel state information at the receiver. The detector is based on the generalized likelihood-ratio test (GLRT) paradigm. We derive detection metrics for the cases when the noise variances at the receiver are known and unknown. Noise here may comprise both thermal noise and interference. Simulation results show remarkable performance gains of the GLRT-based detector with unknown noise variances compared to the training-based maximum-likelihood detector with unknown noise variances when the noise variances in two slots are different. Furthermore, the performance of the GLRT-based detector with unknown noise variances is nearly the same as that of the training-based maximum-likelihood detector with known noise variances.

TL;DR: The basic idea behind the Base Station Application Optimizer is to replace the traditional base station with a smart entity, capable of analyzing and optimizing the user data in the application level, which can prevent unnecessary data from travelling though the bottlenecked backhaul network.
Abstract: Expectation and requirements for future wireless communication systems continue to grow and evolve. Long-Term Evolution (LTE) is a recent effort taken by cellular providers and equipment vendors to step into wireless broadband market. The key enhancements target an introduction of new all-IP architecture, enhanced link layer and radio access. In LTE, one of the recurring problems is the bottlenecked backhaul links, connecting the cell sites with the core network. The basic idea behind the Base Station Application Optimizer is to replace the traditional base station with a smart entity, capable of analyzing and optimizing the user data in the application level. In particular, such unit can prevent unnecessary data from travelling though the bottlenecked backhaul network. The benefits of such entity are reduced latency, jitter and network deployment costs.

TL;DR: In this paper, the authors analyze ICT infrastructure advances having taken place in the European Union, Japan and the United States in last fifteen years, and specify the most significant, present and potential future problems for Polish economy due to its ICT usage backwardness.
Abstract: Information and telecommunication technology development is undeniably one of the most important factors for global knowledge diffusion and digital society creation processes in the contemporary world economy. The purpose of this paper is to analyze ICT infrastructure advances having taken place in the European Union, Japan and the United States in last fifteen years, and - based on the analysis results - to specify the most significant, present and potential future problems for Polish economy due to its ICT usage backwardness. While ICT infrastructure development level in Poland is closing to the EU averages, still the vital issue is lack of Internet usage possibilities and increasing digital divide between urban and rural regions, which in the near future can constrain a socioeconomic growth and competitiveness of Polish economy.
