Abstract: A method is disclosed for selectively turning off a switch arrangement for current distribution. A corresponding switch arrangement is also disclosed, including an upstream switch and a directly downstream switch connected in series, each switch being configured to check a current condition associated therewith. Connected between the upstream switch and the downstream switch is a communication link onto which the downstream switch puts a delay signal if its current condition is met and there is no fault present. Following reception of the delay signal, the upstream switch opens only after a delay time. In order to ensure turning off when there is a fault in the opening of a downstream switch even in the case of small overcurrents, when the current condition is met and the fault that prevents opening occurs, the downstream switch puts a fault report onto the communication link that trips the upstream switch.

Abstract: To solve a problem that unless all of a plurality of AICH signature states are correctly decoded, the contents of reception results cannot be recognized and the error rate of signature decoding will be high. In this embodiment, a base station uses, out of a signature combination, the signature of at least one predetermined position to indicate information containing a preamble reception result and uses the signature of a position other than the predetermined position to indicate a transmission profile information number of an uplink channel for notification to a user equipment. Thus, the error rate related to reception results can be reduced as compared with the case where a single signature combination is used to notify all pieces of information.

Abstract: The operating configuration at a node in a wireless communication network, at a neighboring node in the network, and/or at one or more wireless devices supported by the network, is updated based on determining timing information for an impending interruption of a radio link in the network to avoid erroneous operation during the impending interruption, which interruption is associated with an external system. The determination of interruption timing, which may be inferred, e.g., from detecting prior interruptions, or which may be known from information about the external system, and the modification of the operating configuration(s) permits the network to operate with greater stability, control, and accuracy during the interruptions than would be possible if the interruptions were simply treated as intermittent radio link failures.
