A method performed by a radio node for handling a radio fingerprint during network degradation in a wireless communications network is provided. The radio node obtains an indication about a network degradation at location X in the wireless communications network. The radio node decides whether one or more radio fingerprints of respective one or more User Equipments, UEs, are suffering from the network degradation at location X. When one or more radio fingerprints of respective one or more UEs are suffering from the network degradation at location X, the radio node provides to the one or more UEs an indication that the location X is suffering from the network degradation. The indication enables the one or more UEs to handle their respective radio fingerprints during the network degradation at location X.

Systems and methods are disclosed herein for logging of measurement results performed while a wireless communication device is in an inactive or idle state such that the logged information includes information that indicates a status of the respective carrier when logging the measurement results. In one embodiment, a method performed by a wireless communication device comprises receiving a measurement configuration(s) for performing early measurement on a carrier and performing the early measurement on the carrier in accordance with the measurement configuration(s) to provide measurement results. The method further comprises logging the measurement results along with information that indicates a status of the carrier when logging the measurement results. By logging the information that indicates the status of the carrier when logging the measurement results, operations performed based on the measurement results can be more reliable.

Configuration of measurement requirements on cells and beams in NR is made more efficient by, in a user equipment, UE, receiving, information from a network node, which information indicates: a first number K of beams to be measured by the UE, and a second number L of cells in which the UE is required to measure the first number K of beams. The UE then carries out measurements using the received information; and performs at least one operational task based on a result of the measurements.

A method performed by a radio network node for handling a radio degradation in a wireless communication network. The radio network node detects the radio degradation in a radio coverage area served by the radio network node. The radio network node further identifies at least one target wireless device to inform about the radio degradation.

Methods and apparatuses provide a mechanism to account for timing errors of a wireless device () in positioning measurements. In one example, a wireless device () performs reference-signal transmissions or measurements and sends information to a network node () that is involved in positioning of the wireless device (). The information indicates associations of the reference-signal transmissions or measurements with respective timing groups of the wireless device (). Each timing group represents a related set of transmission or reception timing errors within the wireless device (). Based on the information, the network node () accounts for the different timing-group associations when performing positioning calculations that are based on the reference-signal transmissions or measurements performed by the wireless device ().

A method and system are disclosed for a network node or wireless device (WD) to communicate with another WD or network node. The node or WD is configured to perform at least one timing measurement over a measurement period (T) on signals transmitted between the node or WD and another node or WD and, during T, determine if there is any change in a fixed time offset (FTO) used by the nodes for transmitting a reference signal.
