A transmitting device includes a packet generator that generates k (k: an integer of 2 or more) number of data packets as transmission targets, a coder that generates n (>k) number of coded packets by coding the k number of data packets, a transmission controller that instructs that the coded packets are to be transmitted or the transmission of the coded packets is to be interrupted, and a first transmitter that sequentially transmits the coded packets in response to a transmission instruction from the transmission controller. A receiving device includes a receiver that receives the coded packets, a decoder that decodes the coded packets, and a second transmitter that transmits a transmission interruption request packet to the transmitting device in a case where a first condition in which the coded packets are able to be decoded is satisfied. The transmission controller causes the first transmitter to interrupt the transmission of the coded packets in response to the transmission interruption request packet.

Embodiments of the disclosure provide a method and device for performing communication. The method comprises: determining a target transmission pattern from a set of candidate transmission patterns, wherein each of the candidate transmission patterns contains a DL transmission part and/or a UL transmission part, and the candidate transmission patterns differ from one another in terms of time durations of the respective DL transmission parts and/or the UL transmission parts; and performing communication between a network device and a terminal device by using the target transmission pattern.

Embodiments of the disclosure provide a method and device for performing communication. The method comprises: determining a target transmission pattern from a set of candidate transmission patterns, wherein the target transmission pattern is indicated by a signal including one or more of: a reference signal, a signal for performing CRC, and a feedback signal; and performing communication between a network device and a terminal device by using the target transmission pattern.

Provided is s a method for a base station to allocate a time interval resource to transceive a downlink data channel (PDSCH) or an uplink data channel (PUSCH). The method include allocating a time interval resource for each OFDM symbol on the basis of a slot or a mini-slot, transmitting, to a terminal, time interval resource configuration information including OFDM symbol allocation data for OFDM symbols used for data channel transception in the slot or the mini-slot, and transmitting, to the terminal, control information selecting one of the symbol allocation data included in the time interval resource configuration information.

A method for transmitting data, performed by a transmitting apparatus in a wireless communication system, includes: transmitting a last acknowledged mode data (AMD) packet data unit (PDU) segment to a receiving apparatus, and activating a retransmission timer; identifying whether status report transmitted by the receiving apparatus is received until expiration of the retransmission timer; and when the status report is not received until the expiration of the retransmission timer, and a new AMD PDU and a retransmission-pending AMD PDU are not present in a data buffer, retransmitting the last AMD PDU segment to the receiving apparatus.

Provided is a method for correcting errors in a data transmission network, comprising: transmitting a plurality of uncoded information packets across a network path; transmitting a plurality of coded packets for recovering information packets lost in transmission across said network path, the coded packets being temporally interspersed among said uncoded information packets, wherein the coded packets are encoded based on information packets transmitted prior to a previously transmitted coded packet; and determining the interspersion of the coded packets according to a packet loss rate.

A method for transmitting acknowledgement/negative-acknowledgement (ACK/NACK) information of a user equipment (UE) configured with two serving cells including a first serving cell and a second serving cell, the method including receiving two transport blocks (TBs) through a downlink subframe of the first serving cell, receiving one TB through a downlink subframe of the second serving cell and transmitting ACK/NACK information informing ACK/NACKs for the two TBs and the one TB through an uplink subframe of the first serving cell, wherein the ACK/NACK information informs the ACK/NACKs for the two TBs and the one TB by a combination of one resource selected from a plurality of candidate resources and two bits transmitted through the one resource.

A payment reader and a merchant device may communicate over a wireless connection. Reliable and unreliable packets may be transmitted over a single messaging path. Each of a plurality of unreliable packet may include a data payload and a packet identifier. The unreliable packets and a reliable packet may be transmitted over the single messaging path during a first connection event. A response to the reliable packet may be received during the second event and may include a received packet listing. If the received packet listing indicates that any of the unreliable packets were not received, any unreliable packet that was not received may be retransmitted.
