Title (EN) METHOD, COMMUNICATION SYSTEM AND COMMUNICATION UNIT FOR PROTECTING INCUMBENT WIRELESS SERVICES
(FR) PROCEDE, SYSTEME DE COMMUNICATION ET UNITE DE COMMUNICATION PERMETTANT DE PROTEGER DES SERVICES SANS FIL TITULAIRES
Abstract:
(EN) The invention relates to a Method, a Communication System and an Communication Unit for protecting incumbent services whereas in the incumbent services first information is exchanged between first communication means by radio frequency transmission within a first bandwidth using a first protocol and second information is exchanged between second communication means by radio frequency transmission within a second bandwidth using a second protocol and the second bandwidth is overlapping and larger than the first bandwidth. The problem to be solved is to reduce or to eliminate an interference of secondary services to incumbent services. The problem is solved by ascertaining the presence of any first information exchange between said first communication means; transmitting a protecting information at least about the presence of a first information exchange to at least one of the second communication means; inhibiting said at least one of the second communication means to use the radio frequencies used for exchanging the first information for transmitting the second information and transmitting the second communication within a frequency range wherein the radio frequencies used for exchanging the first information for transmitting the second information are notched.
(FR) La présente invention se rapporte à un procédé, à un système de communication et à une unité de communication permettant de protéger des services titulaires. Dans lesdits services titulaires, des premières informations sont échangées entre des premiers moyens de communication par l'intermédiaire d'une transmission radiofréquence dans une première largeur de bande à l'aide d'un premier protocole, et des secondes informations sont échangées entre des seconds moyens de communication par l'intermédiaire d'une transmission radiofréquence dans une seconde largeur de bande à l'aide d'un second protocole, la seconde largeur de bande chevauchant la première largeur de bande et étant plus importante que cette dernière. Le but de l'invention est de réduire ou d'éliminer les perturbations des services titulaires causées par des services secondaires. A cette fin, l'invention consiste : à confirmer la présence d'un éventuel premier échange d'informations entre lesdits premiers moyens de communication ; à transmettre, à au moins l'un des seconds moyens de communication, des informations de protection relatives au moins à la présence d'un premier échange d'informations ; à inhiber le ou lesdits seconds moyens de communication, afin d'utiliser les fréquences radio servant à échanger les premières informations pour transmettre les secondes informations ; et à transmettre les secondes informations dans une bande de fréquences, les fréquences radio qui servent à échanger les premières informations et à transmettre les secondes informations faisant l'objet d'une élimination de bande ('notching').
