  • Publication number: 20230319666
    Abstract: Disclosed is a method performed by an access point, AP (120), of a WLAN (125), for handling a wireless device (140) connected to the AP (120). The method comprises obtaining information on signal quality of signals sent between the AP (120) and the wireless device (140), and when the obtained information on signal quality reveals that the signal quality is below a signal quality threshold, determining a current value of a wireless device characteristic. The method further comprises obtaining, from a pre-emptive handover system (150), an estimation of a likelihood of the wireless device (140) disconnecting from the WLAN for the current value of the wireless device characteristic, wherein the likelihood was determined from statistical information of earlier handling of the wireless device (140) by the AP (120) for different values of the wireless device characteristics.

    Abstract: A method performed by a system having a plurality of base station systems, each base station system comprising a baseband unit, BBU and a radio unit, RU interconnected via a fronthaul connection that is shared between the base station systems. Fronthaul capacity information on transmission capacity of the shared fronthaul connection and information on required capacity for transmission and/or reception of wireless signals by the RU of the respective base station system are obtained. Time unit transmission restrictions for the respective base station system is determined based on the fronthaul capacity information and on the information on required capacity, which time unit transmission restrictions results in fronthaul usage below the transmission capacity of the part of the fronthaul connection. Information on the determined time unit transmission restrictions is sent to the BBU of the respective base station system.
