摘要： Recovery control is provided for recovering data packet flow control between a network node (14) and a radio base station (18) over a radio network interface (2). The base station communicates with at least one user equipment, UE, (10) over a radio interface (3) and measures information relating to a data transmission rate over the radio interface and an amount of a downlink packet queue (22) in the base station associated with the UE communication. In one embodiment, the base station sends at least some of the measurement information to the network node. A process controller (52, 40, 84) in the network node processes the measurement information to determine a desired amount to be stored in the downlink packet queue. The process controller determines a commanded bit rate to transmit data from the network node to the downlink packet queue based on the determined desired amount and transmits data to the radio base station in accordance with the commanded bit rate.

摘要： Embodiments herein relate to a method in a radio network node (12) for enabling management of radio resources in a radio communications network, which radio network node (12) serves a first cell (11). The radio network node measures a received total power value at the radio network node (12) in the first cell (11). The radio network node (12) computes a factor indicating a load in the first cell (11). The radio network node (12) estimates a noise floor level in the first cell (11). The radio network node (12) computes a utilization probability value of the load in the first cell (11) and a neighbour cell interference value simultaneously in a non-linear interference model. This is based on the measured received total power value, the computed factor,and the estimated noise floor level in the first cell (11), which neighbour cell interference value is an interference from at least one second cell (14) affecting said first cell (11), and where at least one of the utilization probability value of the load in the first cell (11) and the neighbour cell interference value is to be used for managing radio resources in the radio communications network.

摘要： Embodiments herein relate to a method in a radio base station (12) for performing thermal noise power floor estimation in a radio communications network (1). The radio base station (12) computes table entries for a table for a transcendental function evaluation, which table is of minimized size with a range of table entries defined by a smallest table entry, a largest table entry, and a number of table entries. The radio base station (12) further estimates a thermal noise power floor by performing a transcendental function evaluation in computing a product representing a cumulative probability function, which cumulative probability function is related to the thermal noise power floor. The transcendental function evaluation is performed by using table look ups of the table with the computed table entries.
