A method may be provided to operate a node of a radio access network communicating with a wireless terminal. The wireless terminal may be configured to provide a transmit buffer for data to be transmitted to the node during transmission time intervals, to transmit packets of the data from the transmit buffer to the node during respective transmission time intervals, and to provide buffer indicator bits with respective packets of the data during the respective transmission time intervals. The method may include: receiving a packet including data and a buffer indicator bit from the wireless terminal during a respective transmission time interval; and providing an estimate of a quantity of data in the transmit buffer at the wireless terminal responsive to a status of the buffer indicator bit. Related wireless terminals and network nodes are also discussed.

The invention relates to a method in a radio communications network for controlling a transmission power of a user equipment () transmitting data to a radio base station () in the radio communications network. The radio base station () retrieves a target signal to interference ratio value and measures a signal to interference ratio of a signal transmitted with a current transmission power from the user equipment (). The radio base station () then determines a user equipment capability of power control of the user equipment (). Furthermore, the radio base station () computes a power control command based on the measured signal to interference ratio, the retrieved target signal to interference ratio, and the user equipment capability of power control, which power control command indicates a power control adjustment step of the user equipment (). The radio base station () then transmits the power control command to the user equipment (). The user equipment () calculates a transmission power step based on said received power control command and adjusts the transmission power by applying the calculated transmission power step to the current transmission power.
