Apparatus, and associated method, for facilitating communications in a radio communication system through use of ultrawide band signals
First Claim
1. Apparatus for a radio communication system having a network part and a mobile node selectably operable to communicate data signals by way of radio channels susceptible to fading with the network part pursuant to a communication service, said apparatus for facilitating communication between the mobile node and the network part, said apparatus comprising:
- an ultrawide band signal detector embodied at the mobile node, said ultrawide band signal detector for detecting ultrawide band signals generated by the network part, the ultrawide band signals generated by the network part at least pseudo-randomly and communicated by way of the radio channels susceptible to fading;
a signal replicator for generating replica signals, the replica signals replicas of the ultrawide band signals prior to communication thereof upon the radio channels that are susceptible to distortion;
a comparator adapted to receive indications of the ultrawide band signals detected by said ultrawide band signal detector and to receive indications of the replica signals generated by said signal replicator, said comparator for comparing the indications of the ultrawide band signals together with the indications of the replica signals, comparisons made by said comparator used to facilitate the communication between the mobile node and the network part.

Abstract
Apparatus, and an associated method, for a radio communication system having a sending station and a receiving station. The sending station sends data pursuant to a communication service and ultrawide band signals pursuant to a selected time-hopping sequence. An ultrawide band signal detector is positioned at the receiving station. The ultrawide band signal detects the ultrawide band signal transmitted thereto. Correlation is made between the detected ultrawide band signal and a locally-generated replica signal. Correlations therebetween are used to facilitate various receiving station operations, such as equalization operations upon received data, time synchronization of the receiving station to the sending station, and position determination of the positioning of the receiving station.

16. A method for facilitating communication in a radio communication system having a network part and a mobile node selectably operable to communicate data signals, by way of radio channels susceptible to fading, pursuant to a communication service, said method comprising the operations of:
-
detecting, at the mobile node, ultrawide band signals generated by the network part, the ultrawide band signals generated at the network part at least pseudo-randomly and communicated by way of the radio channels susceptible to fading;
generating replica signals at the mobile node that are replicas of the ultrawide band signals prior to communication thereof upon the radio channels that are susceptible to distortion;
comparing indications of the ultrawide band signals together with indications of the replica signals, comparisons made therebetween used to facilitate the communication between the mobile node and the network part. - View Dependent Claims (17, 18, 19, 20)
