A method, system and apparatus are disclosed. According to one or more embodiments, a wireless device configured to communicate with a network node is provided. The wireless device configured to: before expiration of a first timer, perform first measurements of a cell while meeting a first performance target, and after the first timer has stopped, perform second measurements of the cell while meeting a second performance target different from the first performance target.

Enhanced procedure for early measurement reporting

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.

Methods of logging early measurement carrier status

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.

Systems and methods for collection and reporting of Channel Occupancy (CO) statistics for network tuning are provided. In some embodiments, a method performed by a wireless device for tuning one or more parameters of a network comprises obtaining a configuration for CO measurement and reporting. The method also includes obtaining a plurality of CO measurements based on the obtained configuration for CO measurement and reporting. One or more of the plurality of CO measurements are obtained when a Radio Resource Control (RRC) state of the wireless device is RRC_INACTIVE or RRC_IDLE. One or more of the plurality of CO measurements are obtained when the RRC state is RRC_CONNECTED. The method also includes reporting a result of one or more of the plurality of CO measurements to a network node. This might allow improved tuning of networks such as tuning of mechanisms that are used to compensate for potential CCA/LBT failures.

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. The radio network node then transmits a notification of the detected radio degradation to the at least one identified target wireless device.

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 ().

Methods and apparatuses to account for timing errors of a user equipment in positioning measurements

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. If there is a change in the FTO over T, the network nodes or WDs are configured to perform an operational task and, if not, continue performing the timing measurement over T. The operational tasks may include discarding the timing measurement, restarting the timing measurement, extending the measurement time, informing another node about a change in the FTO or informing another node about an action taken by the network node or WD.
