Benefits of technology

[0017]By virtue thereof, it is prevented that a terminal UE always has to blindly try to find the network node eNB from the shared spectrum. Offering auxiliary channels thus also speeds up the re-deployment of the shared spectrum. In addition, configuring virtual channels also speeds up the device attachment to eNB and clarifies the deployment on shared bands.

Problems solved by technology

As licensed band operation has been increasingly utilized, portions of the radio spectrum that remain available have become limited.
The quality of the communication link may change quite rapidly due to an unknown interferer (e.g. another system's device or devices occupying the band) or if the incumbent user decides to deploy the channel.

Embodiment Construction

[0025]Exemplary aspects of the invention will be described herein below.

[0026]Generally, according to one (at least partial) aspect, the invention is implemented in a network node such as an evolved Node_B, eNB. Likewise, according to another (at least partial) aspect, the invention is implemented in a communication terminal device such as a user equipment UE. Both aspects are at least partly interrelated. The invention is mainly implemented in a device such as a processor or chipset residing at the eNB side or at the UE side. Such processor of chipset may be implemented hardware independent, i.e. independent of the hardware technology such as MOS (Metal Oxide Semiconductor), CMOS (Complementary MOS), or ECL (Emitter coupled Logic), or any others. The chipset may be implemented as a DSP (digital signal processor) or as an ASIC (application specific integrated circuit) or the like. Alternatively, the functionality thereof may be realized, at least in part, as software or computer pro...

Abstract

The present invention proposes methods and devices for mobile communication deployed on shared bands, which enhance reliability of channels such as control channels. According to an aspect thereof, at a communication terminal, a list of channels useable for communication is maintained, information on the usability of a currently used channel is obtained, and it is switched to one of the channels of the list of useable channels if the currently used channel becomes unusable. The invention encompasses also corresponding computer products as well as methods, devices and computer products residing at a network node.

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to enhancements on channel reliability in scenarios operating on shared band. More particularly, the present invention addresses methods, devices and computer product claims for systems operated on shared bands, which enhance reliability of channels.BACKGROUND[0002]Mobile data transmission and data services are constantly making progress. With the increasing penetration of such services, a need for increased bandwidth for conveying the data is emerging. In hitherto known scenarios, networks operated on reserved bands (licensed bands) within the available spectrum, which were reserved for the particular network. As licensed band operation has been increasingly utilized, portions of the radio spectrum that remain available have become limited. Thus, operators, service providers, communication device manufacturers, and communication system manufacturers, are all seeking efficient solutions to utilize unlicensed shared ...
