摘要： In a UMTS Terrestrial Radio Access Network (UTRAN), a method of switching from a current common channel to a dedicated channel for a UE. The method comprises estimating the round trip delay for data packets travelling between the UE and a peer node with which the UE is communicating. The product of the estimated round trip delay and the bandwidth of the common channel or the dedicated channel is determined and a threshold defined on the basis of that product. A switch from the common channel to a dedicated channel is initiated when the fill level of the RLC buffer(s) in the UTRAN for the UE reaches or exceeds said threshold.

摘要： In a method for the transmission of data packets (D) from a transmitter (TR) to a receiver (RE) identification of transmitted data packets are stored. Defective data packets (D) are detected by the receiver (RE), status messages (S) which request defective data packets for retransmission are sent from the receiver (RE) to the transmitter (TR) and retransmissions of requested data packets are performed according to the status messages (S). The transmitter (TR) evaluates a first status message (S11) with an identification of at least one first requested data packet and retransmits the first data packet. The transmitter (TR) then initializes a timing unit according to the retransmission of the first data packet, wherein the timing unit or a threshold for the timing unit is attributable to the first data packet. When the transmitter evaluates a further status message (S12) and detects at least one further data packet that is requested for a retransmission, it selects the further data packet if the timing unit has reached the threshold or if the identification of the further data packet is different from the identification of the first data packets. Only the selected data packets are retransmitted. A transmitter and software programs embodying the invention are also described.

摘要： A method and an apparatus for transmitting error-tolerant data is disclosed employing the ARQ technique, wherein the retransmission of erroneous data is performed up to the point where the remaining amount of errors is acceptable (for instance because the erorrs will not be perceived by the recipient of the information, which can be a person or a higher level protocol with additional error correction capabilities). The number of data blocks (RLC) detected as erroneous is employed to define a reliability measure (RM) and a request for retransmission of the erroneous data blocks is performed until a desired reliability threshold (RT) is reached. An additional threshold with a higher value than the first one can be employed to request for optional retransmission when the reliability measure (RM) is between the first and the second threshold. The retransmission will be performed only if further conditions such as channel availability are met.

摘要： A method for a data transmission with ARQ protocol using multicast groups such as GSM, GPRS or UMTS in a mobile communication system is described. Data is transmitted in data blocks (PDU) from a transmitter (T) to a plurality of receivers (R1-RM), said data blocks (PDU) being identifiable by an identification (e.g. a sequence number). The receivers (R1-RM) send status indications to the transmitter (T) whether a data block (PDU) is correctly received. The transmitter (T) is adapted to perform retransmissions according to the status indications and has a transmission window comprising the transmission status for the data blocks (PDU) according to their identification. In the method, a synchronization to the transmitter (T) is performed for at least one first of said receivers (Ri), wherein a range of identifications of transmitted data block (PDU) is selected in said synchronization. The transmitter (T) deletes the transmission status for the selected range of identifications from the transmitter window and the first receiver (Ri) stops sending status indications for the data blocks (PDU) corresponding to the selected range of identifications. In addition, a transmitter and a computer program implementing the method are described. As an example the transmitter can be a RNC extending the RLC and MAC-HSPDA protocols standardized by 3GPP for obtaining efficient and reliable point-to-multipoint radio links.

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： In a wireless communication network where base stations receive protocol data units (PDUs) from mobile stations for decompression and deciphering for ordered, sequential transfer as service data units (SDUs) to an associated core network, the teachings presented herein provide a method of supporting seamless handover of a mobile station from a source base station to a target base station. By way of example, the teachings herein apply to a network based on the E-UTRA specifications, as promulgated by the 3GPP. However, that example is non-limiting, as the teachings herein apply to any network that employs in-sequence data delivery and duplicate data detection at handover. Broadly, the source base station forwards out-of-sequence SDUs and corresponding sequence number information to the target base station in support of seamless handover, and the target base station uses that information to request retransmissions as needed for packet reordering.

摘要： A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. One embodiment detects lost synchronization errors for NDI-based retransmission protocols and restores synchronization by sending an explicit RESET message. In response to the RESET message, the transmitter aborts the transmission of a current PDU and transmits a new PDU and corresponding NDI. Another embodiment prevents protocol synchronization errors by sending scheduling grants on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.
