ACTIVE QUEUE MANAGEMENT FOR WIRELESS COMMUNICATION NETWORK UPLINK

摘要

FIELD: radio engineering, communication.;SUBSTANCE: invention relates to communication systems. According to the ideas presented herein, a base station implements active queue management (AQM) for uplink transmissions from user equipment (UE), e.g. a mobile terminal. The base station, e.g., an eNodeB in a long term evolution (LTE) network, uses buffer status reports, for example, to estimate packet delays for packets in the UE uplink transmit buffer. In one version of the method of AQM (base station) for the uplink includes estimating at least one of a transmit buffer size and a transmit buffer queuing delay for UE, and selectively dropping or congestion-marking packets received at the base station from the UE. The selective dropping or marking is based on the estimated transmit buffer size and/or the estimated transmit buffer queuing delay.;EFFECT: reduced signal transmission delay.;22 cl, 7 dwg
