Methods for handling a pattern-based guard band

Abstract

Methods in a first, a second and a third node in a wireless communications network for handling a pattern-based guard band. The first node configures the pattern-based guard band. The pattern-based guard band comprises a pattern, which comprises at least a first set and a second set of time resources. The first set of time resources is associated with a first guard band configuration. The second set of time resources is associated with no guard band configuration or with a second guard band configuration which is different from the first guard band configuration. The method in the second node comprises obtaining the configured pattern-based guard band and adaptively configuring one more actions in response to the obtained pattern-based guard band. The method in the third node comprises sending a request to a first node to configure the pattern-based guard band. The first, second and third nodes are also described.
