Recovery control is provided for recovering data packet flow control between a network node and a radio base station over a radio network interface. The base station communicates with at least one user equipment, UE, over a radio interface and measures information relating to a data transmission rate over the radio interface and an amount of a downlink packet queue 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 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.

Methods and apparatuses for recovering data packet flow control against radio base station buffer run away

An access beacon sequence is transmitted by an entity in a communication system, the access beacon sequence comprising at least one access beacon packet. A method includes segmenting the access beacon sequence into access beacon segments, by segmenting said at least one access beacon packet. For each one of the access beacon segments, an access beacon portion is generated to include a corresponding one of the plurality of access beacon segments and an indicator indicating that the access beacon portion refers to an access beacon sequence of the communication system, so as to obtain a plurality of access beacon portions corresponding to the plurality of access beacon segments. Each access beacon portion of the plurality of access beacon portions is transmitted on a respective frequency channel amongst a plurality of frequency channels, where different access beacon portions are sent on different frequency channels according to portion-frequency association information.

Access beacon transmission and reception schemes

Recovery control is provided for recovering data packet flow control between a network node () and a radio base station () over a radio network interface (). The base station communicates with at least one user equipment, UE, () over a radio interface () and measures information relating to a data transmission rate over the radio interface and an amount of a downlink packet queue () 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 () 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.
