    摘要: Methods and apparatus for processing error control messages, such as RLC ARQ control messages, are disclosed. An exemplary method comprises signaling a medium access controller (MAC) that link resources are needed for transmitting data, receiving an indication from the MAC that link resources for transmitting the data are scheduled, and generating an error control message after receiving said indication, based on a current error control status. The error control message is then forwarded to the MAC for transmission. Because the generation of an error control message is delayed until resources for its transmission are scheduled, the queuing of stale control messages is avoided.

    摘要: According to the teachings presented herein, a base station implements active queue management (AQM) for uplink transmissions from user equipment (UE), such as 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's uplink transmit buffer. In one embodiment, a (base station) method of AQM for the uplink includes estimating at least one of a transmit buffer size and a transmit buffer queuing delay for a 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.

    摘要: The present invention provides a stall avoidance mechanism that may be used alone or in conjunction with an ambiguity avoidance mechanism in an ARQ protocol. Both mechanisms decrease data delays and increase data throughput rates. Stall avoidance is accomplished by determining whether a stall condition exists with respect to receiving a missing data unit. In one example, only a single timer is needed to avoid stalls. Retransmission ambiguities may be avoided using a retransmission window in the transmitter and/or a receive window in the receiver. Although each mechanism may be used independently of the other, a preferred example embodiment uses a stall avoidance timer, a retransmission window in the transmitter, and a receive window in the receiver.
