A method is provided for transmitting a physical layer protocol data unit (PPDU) in a wireless communication system. For a first data stream associated with a first PPDU to be transmitted via a first channel, a wireless device includes a first data block, a first header indicating a first modulation and coding scheme (MCS), and a first physical layer service data unit (PSDU) in the first data stream. For a second data stream associated with a second PPDU to be transmitted via a second channel, the wireless device includes a second data block, a second header indicating a second MCS and a second PSDU in the second data stream. The wireless device performs a padding procedure to at least one of the first data stream and the second data stream, and transmits the first data stream and the second data stream by using the first PPDU and the second PPDU.

The present disclosure relates to a communication apparatus and a communication method, and a program which make it possible to achieve higher reliability.

When a packet is distributed to a plurality of lanes and transmitted, at least one of a packet header or a packet footer of the packet is transmitted independently in each of the lanes. The packet footer transmitted in each of the lanes is CRC calculated from a payload of the packet distributed to each of the lanes corresponding thereto, and the packet header transmitted in each of the lanes includes word count indicating the number of bytes of a payload of the packet distributed to each of the lanes corresponding thereto. The present technology can be applied to, for example, a communication system used for connecting an on-board camera.

A method performed by a first network node, for transmitting a RLC UM, PDU, to a second network node is provided. The first network node and second network node operate in a wireless communications network. When detected that the RLC UM PDU has failed to be transmitted over a first channel, the first network node decides to redirect the RLC UM PDU to be transmitted over a second channel. The first network node divides the RLC UM PDU into two or more re-segmented RLC UM PDUs. The first network node then transmits the re-segmented RLC UM PDUs to the second network node over the second channel. Each re-segmented RLC UM PDU comprises the following indications: (a) that the re-segmented RLC UM PDU is re-segmented, (b) an order indicator related to the re-segmented RLC UM PDU, and (c) whether or not the re-segmented RLC UM PDU is a last re-segmented RLC UM PDU out of the two or more re-segmented RLC UM PDUs.

Disclosed herein are techniques to provide an indication of bandwidth to establish a TxOP using channel bonding. An information element may be generated to include an RTS frame or a CTS frame and an indication of bandwidth in a parity portion of the information element. The indication of bandwidth may be included by using 16 bits of the parity bits of parity bytes for a PHY header of the information element.

A method by which a signal transmission device transmits packets in a communication system is provided. The method includes the operations of, generating a source symbol block including one or more source symbols having the same length by using a source packet block including one or more source packets; generating a restoration symbol block generated using one or more restoration symbols by performing a forward error correction (FEC) coding operation on the source symbol block; generating an FEC source packet including the source packets and an FEC payload identifier (ID) and transmitting the FEC source packet to a lower protocol; generating an FEC restoration packet including one or more of the restoration symbols and the FEC payload ID and transmitting the FEC restoration packet to the lower protocol; and transmitting FEC configuration information including information on the source symbol block generation operation to a receiver.

Provided is a frame configuration usable for both SISO transmission and MISO and/or MIMO transmission. A frame configurator of a transmission device configures a frame by gathering data for SISO and configures a frame by gathering data for MISO and/or MIMO data, thereby to improve the reception performance (detection performance) of a reception device.

A first communication device determines one or more parameters related to a format of a media access control layer (MAC) data unit for an uplink (UL) multi-user (MU) transmission. The format of the MAC data unit for the UL MU transmission is different than a format of a MAC data unit for an UL single user (SU) transmission. The first communication device generates one or more data units that include the one or more parameters. The first communication device transmits the one or more data units to a plurality of second communication devices to inform the plurality of second communication devices of the format of the MAC data unit for UL MU transmissions by the plurality of second communication devices to the first communication device.

A method and apparatus for generating frames to apply error correction to data including a plurality of consecutive data groups are provided. Upon receiving input of an n-th data group consisting of a plurality of priority groups with different priority levels, the number of first code rate frames, which is the number of frames in the n-th data group for which a first code rate is used, is calculated based on the number of first code rate bits calculated based on the ratio of the length of data in an (n−1)-th data group for which the first code rate is used. The number of second code rate frames, which is the number of frames in the n-th data group for which the second code rate is used, is calculated based on the number of second code rate bits calculated based on the number of first code rate bits. Frames for error correction are generated based on the number of first code rate frames and the number of second code rate frames.

The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). The present invention relates to a method for selecting, by a device, a peer discovery resource (PDR) in a device-to-device (D2D) communication system, the method comprising the steps of: determining a PDR selection range which can be selected by the device; and selecting a PDR in the determined PDR selection range.

Large source data packets having large packet sizes and small source data packets having small packet sizes that are smaller than the large packet sizes are received. The small source data packets and the large source data packets are sent to a receiving device without forward error correction (FEC). The small source data packets are aggregated into a container packet having a header configured to differentiate the container packet from the large source data packets and the small source data packets. The large source data packets and the container packet are encoded with forward error correction to produce FEC-encoded packets to enable forward error correction of the large source data packets and the container packet at the receiving device. The FEC-encoded packets are sent to the receiving device.
