Abstract
The present invention relates to a method for communicating in a network from a first station to a second station, wherein the first station comprises at least one buffer memory for storing data packets to be transmitted, the method comprising the steps of (a) the first station estimating the status of the at least one buffer memory, (b) the first station transmitting at least one buffer status packet representative of the buffer memory status, wherein the method further comprises (c) adapting the value of a first parameter of the buffer status packets on the basis of a data traffic characteristic.
Claims16
A radio station, comprising:
- a transceiver configured to communicate in a network with at least a further radio station;
- at least one buffer memory for storing data packets to be transmitted;
- and
- a buffer controller, wherein the buffer controller is configured to estimate a status of the at least one buffer memory,
- wherein the transceiver is configured to transmit a plurality of buffer status packets, wherein each buffer status packet indicates the status of the at least one buffer memory, and
- wherein the buffer controller is configured to determine a value of a frequency of transmission of the buffer status packets based on a data traffic characteristic of the network.
A radio station, comprising:
- a transceiver, wherein the transceiver is configured to communicate in a radio network with another radio station;
- a buffer memory, wherein the buffer memory is configured to store data to be transmitted by the transceiver;
- and
- a buffer controller, wherein the buffer controller is configured to estimate a status of the buffer memory, and to cause the transceiver to include in data packets to be transmitted by the transceiver, to the other radio station, buffer status reports for the buffer memory,
- wherein the buffer controller is configured to:
- adapt a coarseness for the buffer status reports based on a number of padding bits available in the data packets which include the buffer status reports, and determine a transmission frequency of the data packets which include the buffer status reports based on a data traffic characteristic of the radio network.
A method, comprising:
- a radio station storing in a buffer memory data to be transmitted to a further radio station in a network;
- estimating a status of the buffer memory;
- including buffer status reports for the buffer memory in data packets;
- adapting a coarseness for the buffer status reports based on a number of padding bits available in the data packets, and determining a transmission frequency of the data packets which include the buffer status reports based on a data traffic characteristic of the network;
- and
- transmitting the data packets including the buffer status reports to another radio station via the network at the determined transmission frequency.
