Transfer apparatus and transfer method
A transfer apparatus for performing transmission and reception of data using a plurality of lanes includes: a transmission control unit configured to, upon receiving a transmission instruction for performing a data transfer in a redundant mode in which the same data is transferred using a plurality of lanes, output transmission data as first data and second data without renegotiation with another transfer apparatus; a first transmission unit configured to transmit the first data output by the transmission control unit via a first lane; and a second transmission unit configured to transmit the second data output by the transmission control unit via a second lane.
ELECTRONIC DEVICE WHICH RECEIVES DATA BY USING SPLIT BEARER AND OPERATION METHOD OF ELECTRONIC DEVICE
An electronic device and a method thereof are provided. The electronic device includes at least one communication processor which receives data via a first cellular communication or a second cellular communication, and an application processor, wherein the at least one communication processor is configured to receive, from a master node corresponding to the first cellular communication, first partitioned data among partitioned data produced by partitioning the data, and receive second partitioned data from a secondary node corresponding to the second cellular communication, identify a first sequence number of the first partitioned data and a second sequence number of the second partitioned data, and induce a decrease in or a stop of transmission of pieces of partitioned data to the electronic device via a node which transmits partitioned data corresponding to a small sequence number.
Packet coding based network communication
A method for data communication between a first node and a second node includes forming one or more redundancy messages from data messages at the first node using an error correcting code and transmitting first messages from the first node to the second node over a data path, the transmitted first messages including the data messages and the one or more redundancy messages. Second messages are received at the first node from the second node, which are indicative of: (i) a rate of arrival at the second node of the first messages, and (ii) successful and unsuccessful delivery of the first messages. A transmission rate limit and a window size are maintained according to the received second messages. Transmission of additional messages from the first node to the second node is limited according to the maintained transmission rate limit and window size.
Data transmission systems and data transmission methods of suppressing data error occurrences due to crosstalk
A data transmission system includes a data transmitter and a data receiver. The data transmitter outputs N-bit transmission data (where N denotes a natural number which is equal to or greater than two). The data receiver receives the N-bit transmission data through N-number of data transmission lines. The data receiver transmits a re-transmission request signal to the data transmitter when the N-bit transmission data inputted to the data receiver are erroneous data. The data transmitter divides the N-bit transmission data in response to the re-transmission request signal and operates in a first data re-transmission mode so that the divided transmission data are resent, together with first ground data, to the data receiver.
METHOD AND APPARATUS FOR OPERATING A TIMER FOR PROCESSING DATA BLOCKS
A timer for processing data blocks is proposed for a receiver of a mobile communications system. If the timer is not running, the timer is started based a data block. The data block has a sequence number higher than a sequence number of another data block that was first expected to be received. If the timer is stopped or expires, the timer is based on a highest sequence number of a data block among data blocks that cannot be delivered to a higher entity. The timer can be used to prevent a stall condition in mobile communications.
SYSTEMS AND METHODS TO OPTIMIZE THE LOAD OF MULTIPATH DATA TRANSPORTATION
A control unit of a multipath data transportation system that optimizes the load of the multiple communication paths of this system when the system transmits a data segment over these paths in parallel with forward error correction. The control unit determines an optimized number of packets to send over each path based on a prediction of quality for each path. The transmitted packets include systematic packets and coded packets.
Signal transmission device and method, and signal reception device
The signal transmission device converts a K-bit original signal into an N-bit (N is greater than K) transmission signal in which the number of a logic high bit is identical to the number of a logic low bit, according to a lookup table in which a plurality of K-bit original signals are associated with a plurality of N-bit transmission signals by 1:1 correspondence, and transmit the N-bit transmission signal via N signal lines such that each line carries one bit, thereby minimizing the noise affecting the K-bit original signal.
Transmission and reception system, data reception apparatus, and data reception method using plural transmision paths
A data reception apparatus connected to a data transmission apparatus via transmission paths includes: error detection circuits that are each provided for each of the transmission paths and that each detect an error in received data that has been received from the data transmission apparatus; storage circuits that are each provided for each of the transmission paths and that each store the received data and read the received data at a reported read position at a reported read timing; a selection circuit that selects one of the transmission paths according to error detection results provided by the error detection circuits; and a report circuit that compares received data stored by a storage circuit corresponding to a selected transmission path with received data stored by each of other storage circuits and, according to a comparison result, reports the read timing and the read position to each of the storage circuits.
WIRELESS COMMUNICATION APPARATUS
According to one embodiment, a wireless communication apparatus includes transmitter circuitry, receiver circuitry and control circuitry. The transmitter circuitry transmits a first frame including first data. The receiver circuitry receives, if the first frame is received by at least a first wireless communication apparatus and a second wireless communication apparatus, a second frame indicating a reception status of the first data by the first wireless communication apparatus and a third frame indicating a reception status of the first data by the second wireless communication apparatus. The control circuitry determines not retransmitting the first data if at least one of the second frame and the third frame indicates that reception has succeeded.
MULTI-PATH MESSAGE DISTRIBUTION AND MESSAGE REASSEMBLY FOR LARGE DATA FLOW USING FORWARD ERROR CORRECTION WITH HIGH-PERFORMANCE COMPUTING (HPC)
A reliable high-throughput data transmission may be accomplished using a multi-path message distribution and a message reassembly with a forward error correction protection. An incoming flow of data from a source is received at an input parser. The incoming flow of data is divided into a plurality of packets by the input parser. The plurality of the packets is encoded with a FEC and transmitted over a network with a plurality of transmission links The transmitted plurality of FEC encoded packets are decoded. The decoded plurality of packets is merged to an outgoing flow of data with an output multiplexor and the outgoing flow of data is sent to a destination.
