Abstract
A method and apparatus for transmitter assisted Quality of Service (QoS) measurement. Time information is generated by the transmitter and transmitted along with a data transmission. A receiving device determines a QoS measurement based upon the time information and the received data. The time information indicates when the data was made available for transmission, which data transmission blocks belong to a single data transmission, and when a transmitter buffer was emptied. The QOS measurements are performance measurement such as, latency measurements and throughput measurements. The time information indicates a time reference relative to the timing of a wireless interface. The time reference is a System Frame Number (SFN), a Connection Frame Number (CFN), a relative count of frame numbers, a count of sub-frames, or a count of Time Transmission Intervals (TTIs). An aggregated QOS measurement is generated based upon the QOS measurement.
