    摘要: Methods for efficiently controlling the retransmission of data units in a wireless telecommunication system, wherein multiple complementary feedback mechanisms are used to control retransmission. A receiver attempts to decode each received data unit. If a data unit is successfully decoded, the receiver transmits positive feedback to the transmitter; if a data unit is not successfully decoded, the receiver transmits negative feedback to the transmitter. In all cases, the transmitter employs at least first and second feedback mechanisms for transmitting the positive and negative feedback. In an exemplary embodiment, acknowledgement (ACK) and non-acknowledgement (NACK) messages are sent in response to the receipt of each data unit on a first unreliable channel and Status Messages identifying sequence numbers of particular data units are periodically transmitted on a second reliable channel; the receiver preferably removes data units from its transmit window only upon receipt of a Status Message indicating successful decode.

    摘要: The present invention relates to a method and to a transceiver (400) for detecting HARQ transmission failure in a telecommunications system. The transceiver (400) is arranged to execute a HARQ process which is used to generate a transmission of data units to e.g. a eNodeB. The transceiver is also arranged to determine when a maximum number of transmission attempts is reached and when this occurs to flush a HARQ buffer associated with the HARQ process and to detect that a HARQ transmission failure has occurred when the last HARQ feedback received for the current HARQ process is not a HARQ ACK.

    摘要: The present invention relates to a link layer control protocol implementation in a communication system. To improve operative efficiency of the link layer control protocol implementation it is suggested to delay issuance of a retransmission request for a missing data unit during a retransmission delay time period. Therefore, according to the present invention a retransmission request is not issued immediately upon detection of a missing data unit. Therefore, the present invention avoids issuance of false alarm for the missing data unit when it is received during the retransmission delay period.

    摘要: A method of scheduling data for transmission over the air interface of a wideband code division multiple access network, said data being transported over the air interface on a downlink shared channel. The method comprises receiving data in the form of IP packets at a radio network controller, segmenting said IP packets into protocol data units, and forwarding said protocol data units from the radio network controller to a radio base station serving one or more user terminals. The radio network controller identifies to the radio base station the protocol data units belonging to a common IP packet. At the radio base station, each protocol data unit is scheduled for transmission over the air interface in dependence upon the IP packet to which it belongs.

    摘要: A method for use in a cellular communications system in which system traffic can be exchanged between transceivers comprises receiving traffic from a second transceiver at a first transceiver. The traffic includes data units that are each associated with an identifier. The data units are also divided into segments. The method additionally includes sending status information from the first transceiver to the second transceiver. The status information pertains to one or more data units transmitted by the second transceiver. Additionally, sending the status information includes, for non-received and partially received data units, sending information indicating the data units were non-received or partially received and, for partially received data units, sending information indicating which parts of the data units were not received.

    摘要: The invention discloses a method (700) for a cellular system (100), in which traffic can be exchanged between first (110, 120) and second (110, 120) transceivers. The traffic is sent in data units, each of which is given an identifier, and which data units may be divided into segments. A receiving transceiver (110, 120) may send status information in data frames or data units (200, 300) about properly received, partially received, or non-received data units to a sending transceiver, i.e. the transceiver from which the data was sent. In the case (705) of partially or non-received data units, the status information includes (710) information about whether the data unit or units were non-received or partially received, and in the case of one or more partially received data units, which (715) parts of those data units that were not received.
