Abstract: A coupling element connectable to a string of one or more pipes, for example, a drill string of one or more pipes or drill pipes is provided. The coupling element is configured to excite, responsive to a data signal fed to the coupling element, an electromagnetic wave in the string. The coupling element comprises a feed portion at a first end of the coupling element, the feed portion to receive the data signal, a first electrically conductive portion extending from the feed portion towards a second end of the coupling element, the second end to be connected to the string for forming an electrically conductive connection between the first electrically conductive portion and the string, and a second electrically conductive portion extending from the feed portion towards the second end of the coupling element. The first and second electrically conductive portions are arranged so as to define a waveguide. The waveguide expands in a direction from the first end towards the second end.

Abstract: A network node configured for wirelessly transceiving signals for operating in a wireless communication network is to form a response beam pattern responsive to a recognized stimulus of a stimulating node based on a criterion. The network node is to receive a signal indicated a request to influence the criterion and is to influence the criterion based on the request.

Abstract: A user equipment for communication over a wireless network is configured for exchanging portions of signalling data exclusively over the primary component carriers in a first operational mode in a first operational phase; for exchanging the portion of the signalling data of a selected primary component carrier of the primary component carriers of the first component carrier group simultaneously over the selected primary component carrier and over a selected secondary component carrier of the secondary component carriers of the second component carrier group in a second mode in a second phase subsequent to the first one, the second phase being initiated in case a first trigger condition occurs; for using the selected secondary component carrier from the second operational phase in a third mode in a third phase subsequent to the second one as one of the primary component carriers, so that the selected secondary component carrier from the second phase is added to the primary component carriers of the first compo
