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.

Claims

1. A method in a node in a wireless communication network comprising:

obtaining timing information for an external wireless system whose operation is associated with intermittent interruptions of a radio link of the wireless communication network;

determining an interruption timing from the timing information, wherein the interruption timing is referenced to a radio link timing and indicates an impending interruption of the radio link; and

adapting, with respect to one or more wireless devices in communication with the wireless communication network, user scheduling operations at the node according to the interruption timing, to avoid scheduling transmissions to or from the one or more wireless devices during the impending interruption.

2. A node configured for operation in a wireless communication network, the node comprising communication interface circuitry configured for communicating with one or more other nodes in the wireless communication network and one or more wireless devices in communication with the wireless communication network;

and processing circuitry operatively associated with the communication interface circuitry and configured to;

obtain timing information for an external wireless system whose operation is associated with intermittent interruptions of a radio link of the wireless communication network;

determine an interruption timing from the timing information, wherein the interruption timing is referenced to a radio link timing and indicates an impending interruption of the radio link; and

adapt, with respect to the one or more wireless devices in communication with the wireless communication network, user scheduling operations at the node according to the interruption timing, to avoid scheduling transmissions to or from the one or more wireless devices during the impending interruption.
