摘要： A MIMO wireless data transmission system including a data arrangement in which data to be sent is divided for each transmission stream of MIMO with adding an error detection code thereto and thereby resending a subframe's worth of data when an error occurred at the time of resending. It therefore becomes to avoid the same frame being sent again at the time of resending.

摘要： There is provided a device and method for retransmitting error-detected data in a mobile communication system. A transmitter generates S sub-codes Ci (i=0, 1, 2, . . . , S−1) from a physical layer packet (PLP) information stream using quasi-complementary turbo codes, initially transmits the first sub-code C0, and then sequentially transmits the following sub-codes each time a retransmission request is received for the initial transmission or a previous retransmission. Upon receipt of a retransmission request for the last sub-code CS−1, the transmitter transmits the first sub-code C0 and then sequentially transmits the following sub-codes each time a retransmission request is received.

摘要： A method and system for optimizing coding gain that alters the backsearch buffer length and/or the input buffer length of a decoder in response to one or more transmission performance characteristics of the system. The performance characteristics are monitored to determine the performance of the system. The measured transmission performance characteristics are used to control the lengths of the backsearch buffer and the input buffer. The measured transmission performance characteristics along with the backsearch length and/or the input buffer length are analyzed and compared with simulated decoding results. In accordance with the simulated results, the system determines the optimal size of the backsearch buffer and the input buffer needed to achieve a desired performance target. The system adjusts the size of the backsearch buffer length and/or the input buffer length to equal the determined optimal lengths.

摘要： Apparatus, and an associated method, for providing a hybrid automatic repeat request (H-ARQ) scheme for the Medium Access Control Layer of an IEEE 802.11n-compliant wireless local area network system, or other carrier sense multiple access communication system. When a packet delivered to a destination station is unable successfully to be decoded, a negative acknowledgement message is generated and returned to a sending station to identify the failed decoding. Selection is made at the sending station to send information, such as pursuant to a soft combining scheme are pursuant to an incremental redundancy scheme. A detector and selector embodied at the destination station detects whether the packet has been successfully delivered to the destination station and selects in what manner to respond to the sending station in response thereto.

摘要： Confidence calculator 211 finds confidence based on the measurement result of the received SIR. Based on the confidence supplied from confidence calculator 211, ACK/NACK decider 212 makes a decision for the then modulated ACK signal with reference to a predetermined threshold level. For the ACK/NACK decision result, scheduler 251 instructs buffer 252 to transmit new data when an ACK signal is received, and to transmit the data of the previous transmission when a NACK signal is received. By this means, it is possible to prevent loss of the received data in the communication terminal apparatus that occurs when a NACK signal is erroneously received and the data is not retransmitted from the associated communication terminal apparatus.

摘要： A communication system comprises a downlink data channel for the transmission of data packets from a primary station to a secondary station and two uplink control channels, a first channel for transmission of status signals to indicate the status of received data packets and a second channel for transmission of pilot information. In operation, on detection (402) of a data packet the secondary station increases (404) the transmission power of the second channel, thereby enabling the primary station to obtain a better estimate of uplink channel properties and hence increase the accuracy with which it can decode the status signal. The secondary station transmits (406) the status signal, typically either an acknowledgement (ACK) or negative acknowledgement (NACK), and decreases (408) the transmission power of the second control channel signal. The increase and decrease in power are not necessarily identical, for example as a result of the effects of power control.

摘要： A transmission-reception apparatus does not configure ARQ control information from only sequence number, but the transmission-reception apparatus configures the ARQ control information such that the ARQ control information is comprised of one sequence number containing first occurrence of a corresponding packet's error, and bit information representing existence of retransmission requirements about sequence numbers followed on the heels of such the one sequence number.

摘要： A channel structure and mechanisms that support effective and efficient allocation and utilization of the reverse link resources. In one aspect, mechanisms are provided to quickly assign resources (e.g., a supplemental channel) as needed, and to quickly de-assign the resources when not needed or to maintain system stability. The reverse link resources may be quickly assigned and de-assigned via short messages exchanged on control channels on the forward and reverse links. In another aspect, mechanisms are provided to facilitate efficient and reliable data transmission. A reliable acknowledgment/negative acknowledgment scheme and an efficient retransmission scheme are provided. Mechanisms are also provided to control the transmit power and/or data rate of the remote terminals to achieve high performance and avoid instability.

摘要： A method for determining a data rate of next reverse packet data according to ACK/NACK information and rate control information received from a plurality of base stations in a mobile communication system in which a mobile station, located in a soft-handoff region managed by the base stations, transmits reverse packet data to the base stations, and each of the base stations transmits ACK/NACK information and rate control information, indicating a rate-up, rate-down, or rate-hold command, to the mobile station in response to the reverse packet data. The mobile station receives ACK information from at least one of the base stations, receives either ACK information or NACK information from base stations other than the at least one base station, and receives rate control information from all of the base stations. The mobile station determines a data rate of reverse packet data based on rate control information received from a set of base stations that excludes base stations that transmitted rate control information indicating a rate-hold command together with NACK information.
