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
