摘要： Regular data packets are scheduled for transmission from a sender to multiple receivers in a multicast ARQ system. In a joint scheduling and encoding procedure, a composite data packet is formed as a weighted linear combination of regular data packets. The corresponding coding weights are adapted based on feedback information from the receivers about received data packets such the composite packet represents a new linearly independent coding of regular data packets different from any multicast data packet previously received in a selected set of the receivers during the multicast session. A weight vector with at least two different non-zero coding weights adds a further degree of freedom and guarantees the ability to form a composite data packet that represents a new linearly independent coding for transmission.

摘要： A method of operating a node of a radio access network may include transmitting first and second data blocks from the radio access network over respective first and second MIMO layers of a MIMO wireless channel to a wireless terminal during a first TTI. Responsive to receiving a NACK message for the second data block, downlink signaling for a second TTI may be transmitted from the radio access network to the wireless terminal with the downlink signaling including a DTX indicator for the first MIMO layer and a retransmission data indicator for the second MIMO layer. Responsive to receiving the NACK message for the second data block, the second data block may be retransmitted from the radio access network over the second MIMO layer to the wireless terminal during a second TTI.

摘要： A decoding method for decoding information content in at least one data packet, which is transmitted from a sender to a receiver via a data link. The information is represented by a bit sequence, which is transformed into a transmittable redundancy version. The information is initially transmitted for a first time in a first data packet from the sender to the receiver. The information is represented by a first redundancy version, which is self-decodable. An incorrect receipt is confirmed by sending a confirmation from the receiver to the sender. The information is retransmitted at least a second time in a second data packet from the sender to the receiver upon receipt of the confirmation, wherein, for representation of the information, a second redundancy version is used, the selection of which is performed in dependence on a coding parameter, describing whether the redundancy version is self-decodable or not.

摘要： A method and apparatus for retransmission processing in a communication receiver includes improving the performance of Incremental Redundancy (IR) combining and retransmission processing at minimal increased complexity. One aspect of these improvements involves the use of prior decoding results, if the decoding block quality is above a threshold value, rather than or in addition to prior demodulation results, in retransmission processing. That is, the teachings herein propose selectively using the hard bit decisions obtained from decoding previously transmitted data blocks, to improve the decoding of retransmitted data blocks.
摘要翻译：一种通信接收机中用于重传处理的方法和装置包括以最小增加的复杂度改进增量冗余（IR）组合和重传处理的性能。这些改进的一个方面涉及使用先前的解码结果，如果在重传处理中解码块质量高于阈值，而不是或除了现有的解调结果之外。也就是说，本文的教导有选择地使用从先前发送的数据块解码得到的硬比特决定，来提高对重传的数据块的解码。

摘要： A wireless device for implementing Incremental Redundancy (IR) operations includes system processing circuitry operable to perform Physical (PHY) layer operations, Media Access Control (MAC) layer operations and Radio Link Control (RLC) operations of the wireless device. The system processing circuitry further includes an IR control module for processing IR transactions related to a received RLC data block and for tracking an Automatic Repeat Request (ARQ) receiving state and received block bit map and a Layer 1 (L1) module for intercepting and diverting the IR transactions to the IR control module and for passing a correctly decoded RLC data block to the RLC layer operations via the MAC layer operations thereby automatically synchronizing the RLC layer operations. An IR processing module is coupled to the system processing circuitry to perform IR operations on the received RLC data block based upon a direction from the IR control module.

摘要： An apparatus and method for Transmission Time Interval (TTI) reconfiguration in a mobile communication system are provided. The apparatus includes an ACK/NACK determiner, an ACK/NACK controller, and a TTI controller. The ACK/NACK determiner determines if a response signal to be transmitted is ACKnowledgment (ACK) or Non ACKnowledgment (NACK) depending on an error or non-error of data received from a User Equipment (UE). The ACK/NACK controller counts the ACK and NACK determined in the ACK/NACK determiner. The TTI controller identifies if number of the latest ACKs counted in the ACK/NACK controller is continuously generated by preset number of times and, if it is continuously generated by the present number of times, reconfigures a new TTI.
