Abstract: A method, in a base station, provide a mechanism for observing random access performance in a Long Term Evolution network. The random access performance is defined by an access delay. The access delay is a delay from the initial random access attempt until access is granted. The method comprises receiving a respective report from a plurality of user equipment, where each of the respective user equipment has performed a random access process and received a random access grant. The reactive report includes access delay related random access information. The method includes determining a respective access delay, based on each of the access delay related random access information. The determined access delays are used for the estimation of access delay statistics. The random access performance is observed based on the access delay statistics.

Abstract: Method and a network node (110, 910) for enabling position determination of a measurement performed by a user equipment (120) served by a base station (110). The user equipment (120) and the base station (110) are comprised in a cellular communications network (100). A measurement report comprising measurement data associated with the measurement and a time of measurement thereof is received (301, 801) from the user equipment (120). One or more first type of data associated with the user equipment (120) at a respective point in time are retrieved (302, 802), which first type of data is localization corresponding data. Based on the time of measurement, first type of data that corresponds to the time of measurement is determined (303, 803) from the retrieved one or more first type of data. The determined first type of data is associated (304, 804) with the measurement data. The position of the measurement may then be determined based on the first localization corresponding data associated with the measurement data.

Abstract: Methods, arrangement and network nodes for supporting inter-cell coordination of scheduling of radio resources subjected to inter cell interference. The methods involve identifying one or more radio resources which are subjected to inter-cell interference between a first cell and a second cell. The methods further involve deriving a respective service value related to service that could be provided in the respective first and second cell by use of the one or more radio resources. Further, transmissions in the one or more radio resources are controlled based on comparison of the service values, thus enabling inter-cell service value-based scheduling of the one or more radio resources, prioritizing services having the highest value per radio resource.

Abstract: A method in a first radio network node (105, 110, 120) for handling positioning of a first user equipment (110) is provided. The first radio network node (105, 110, 120) defines a criterion relating to at least one measurable radio quality of the first user equipment (110). The criterion is based on historical measurements of the at least one radio quality of at least one second user equipment having experienced a radio event. Fulfilment of the criterion is an indication that the radio event is upcoming for the first user equipment (110). The first radio network node (105, 110, 120) receives a current measurement of the at least one radio quality of the first user equipment (110), for which first user equipment (110) the radio event is currently upcoming. When the criterion is fulfilled, the first radio network node (105, 110, 120) triggers positioning of the first user equipment (110).
