摘要： A base station, mobile station, and/or other terminal device includes physical layer (layer 1) protocol and link layer (layer 2) protocol that both include automatic retransmission request (ARQ) operations. The physical layer and link layer include enhancements that interact with one another to cause the link layer to inhibit ARQ operations while error recovery operations are pending at the physical layer. A transmitter packages link layer packet data units into physical layer frames and transmits the physical layer frames. A receiver responds to indicate either successful or unsuccessful transmission. The transmitting physical layer waits for the response and initiates error recovery operations when required. The receiving link layer, when it detects lost data packets, inhibits its ARQ operations to allow physical layer error recovery operations to complete.

摘要： It is disclosed a method for reducing the frame error rate on a link between a first and second unit of a node of a wireless packet-switched communication network. The first and second units comprise a first and second interfaces, respectively. The first and second interfaces are located at a medium access control layer. The method comprises, at the first interface, associating a sequence number to a frame and transmitting the frame and sequence number over the link to the second interface. The sequence number is indicative of a position of the frame in a sequence of frames transmitted over the link. Further, the method comprises, at the second interface, receiving the frame and reading the sequence number, which is used for determining whether a frame is missing from the sequence of frames. In the affirmative, it is requested to the first interface the retransmission of the missing frame.

摘要： A physical automatic repeat request method implemented by a base station (30) having a transmitter (38) and a receiver (52). A physical layer, at the transmitter (38) receives data and formats the received data into packets having a particular encoding/data modulation. The physical layer transmits the packets and retransmits packets upon failure to receive a corresponding acknowledgment (56) for a given packet. An adaptive modulation and coding controller in the transmitter collects retransmission statistics (60) and adjusts the particular encoding/data modulation using the collected statistics (62).

Each PDU being identified using a sequence number. The transceiver, according to the present invention, is arranged to receive from the other transceiver a status report indicating positively acknowledged PDUs and negatively acknowledged PDUs. The transceiver (100) is further configured to compare sequence numbers in the report with previously acquired sequence numbers from previous reports and to prevent retransmissions of one or several PDUs based on the comparison.

摘要： A method for initiating a storage window of a receiving end (200) in a wireless communications system, which periodically retransmits data packets in an unacknowledged mode, includes after a receiving entity of the receiving end is established, re-established, or after a timer expires (402), initiating a state variable, which is defined to be a sequence number of the highest numbered packet that has been received, according to a sequence number of a received packet (404, 406). An example of the wireless communications system is the Universal Mobile Telecommunications System (UMTS) with a multimedia broadcast/multicast service (MBMS) application.

摘要： An apparatus (102, 104) for transmitting a stream of information bytes, the apparatus (102, 104) includes a mechanism (604, 618, 638) for receiving/transmitting a message specifying a radio link protocol, RLP, round-trip time, RTT, estimate, and a mechanism (604) for conducting an RLP communication session using said RTT estimate to determine negative acknowledgment, NAK, message timing. A first RLP RTT estimate can be established during service negotiation, and is used to determine NAK message timing in a subsequent RLP communication session. Alternatively, a 3-way handshake is performed for generating a first RTT estimate associated with the first RLP communication session, a second RTT estimate, based on the first RTT estimate, associated with a second RLP communication session is established during service negotiation. The second RLP RTT estimate is used to determine NAK message timing in a subsequent RLP communication session.
