    Abstract: In network-based uplink scheduling, users are scheduled by the network for uplink communication between a user side and a network side. In this context, the invention provides an efficient estimation of User Equipment (UE) buffer status on the network side such as at Node B (20), for each of a number of users (10), and determines an uplink scheduling priority order of the users based on the network-estimated buffer status information. The users (10) are allocated communication resources based on the determined uplink scheduling priority order. In this way, the UE buffer status may be considered in the uplink scheduling procedure without explicit UE buffer status reports (that would waste valuable uplink transmission resources) from the UE side. This means that efficient scheduling and optimal exploitation of the uplink transmission resources are ensured, with clearly improved system performance as a result.

    Abstract: The present invention relates to an apparatus and method for controlling a number of user equipments operating in a cellular network. The method comprises receiving an indication that a rise-over-thermal (RoT) measured in a cell is above a threshold. In response to reception of the indication, it is determined (52) if a user equipment, which is in a Radio Resource Control, RRC, state CELL_DCH and served by the cell, has a low data activity in the uplink According to the method, a user equipment, which is in the RRC state CELL_DCH, is served by the cell and is determined to have a low data activity in the uplink, is triggered (54) to change state to a RRC state CELL_FACH. Thereby the contribution of the user equipment to the RoT of the cell may be reduced and it may be possible to avoid dropping users due to congestion control in case of unacceptably high RoT in the cell.

    Abstract: In multi flow high speed downlink packed access, MF HSDPA, communication between a radio network controller, RNC, (105) and two Node Bs (104), redundant RLC PDUs are handled by being discarded in the Node B. The discarding can be controlled via a timer in the Node B or by way of additional signalling between the RNC and the Node B.
