Uplink performance investigations of the service area based beyond 3G system JOINT

The joint transmission and detection integrated network (JOINT) is a novel OFDM-based vNP00 air interface solution for beyond 3G (B3G) mobile radio communications systems WMSL02. JOINT aims at eliminating the multiple access interference (MAI) and improving the system capacity by the application of MIMO techniques applied in the service area (SA) based system architecture. In a SA based structure the intra-SA multiple access interference (MAI) can be easily combated by algorithms like, e.g., joint detection (JD) Kle96,Ver98 in the uplink. The parameters like, e.g., the SA size, the system load and reuse factor show great impacts on the system performances, in terms of the average bit error rate (BER) and the BER statistics. Spectrum efficiency of JOINT is also investigated based on the simulation results

D3.2 First performance results for multi -node/multi -antenna transmission technologies

This deliverable describes the current results of the multi-node/multi-antenna technologies investigated within METIS and analyses the interactions within and outside Work Package 3. Furthermore, it identifies the most promising technologies based on the current state of obtained results. This document provides a brief overview of the results in its first part. The second part, namely the Appendix, further details the results, describes the simulation alignment efforts conducted in the Work Package and the interaction of the Test Cases. The results described here show that the investigations conducted in Work Package 3 are maturing resulting in valuable innovative solutions for future 5G systems.Fantini.

D 3. 3 Final performance results and consolidated view on the most promising multi -node/multi -antenna transmission technologies

This document provides the most recent updates on the technical contributions and research challenges focused in WP3. Each Technology Component (TeC) has been evaluated under possible uniform assessment framework of WP3 which is based on the simulation guidelines of WP6. The performance assessment is supported by the simulation results which are in their mature and stable state. An update on the Most Promising Technology Approaches (MPTAs) and their associated TeCs is the main focus of this document. Based on the input of all the TeCs in WP3, a consolidated view of WP3 on the role of multinode/multi-antenna transmission technologies in 5G systems has also been provided. This consolidated view is further supported in this document by the presentation of the impact of MPTAs on METIS scenarios and the addressed METIS goals.Aziz, D.; Baracca, P.; De Carvalho, E.; Fantini, R.; Rajatheva, N.; Popovski, P.; Sørensen, JH....

Verfahren zum Schaetzen einer Signallaufzeit zwischen einer ersten Teilnehmerstation und einer Funkstation eines Funkkommunikationssystems sowie Teilnehmerstation, Funkstation und Funkkommunikationssystem

DE 102005041121 A1 UPAB: 20070711 NOVELTY - The method involves transmitting an estimating signal (SIG1) to a radio station (NodeB) by a subscriber station (UE1). Another estimating signal (SIG2) is received from the radio station as a response to the former estimating signal. A signal propagation delay is determined based on transmitting and receiving point of time of the estimating signals, where only one carrier frequency is utilized for the estimating signals. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a subscriber station for a radio communication system (2) a radio station for a radio communication system (3) a radio communication system with a subscriber station. USE - Used for estimating a signal propagation delay between a subscriber station (claimed) e.g. mobile telephone, or other movable or stationary device, that is utilized for transmission of images and audio data to facsimile or short message service, multimedia messaging service, electronic mail transmission and/or for Internet access, and a radio station of a multi user radio communication system in a data network e.g. Internet, wireless local area network, high performance radio local area network, Bluetooth network, broadband network with wireless access, and fourth generation or ad-hoc network. ADVANTAGE - The signal propagation delay is determined based on the transmitting and receiving point of time of the estimating signals, where only one carrier frequency is utilized for the signals, thus avoiding the need for a signaling channel for transmitting the signal propagation delay from the radio station to the subscriber station
