A wireless communication device includes a communication interface and a processor that operate to generate a first transmission stream by processing first information based on first parameter(s) and a second transmission stream by processing second information based on second parameter(s). In some examples, the second at least one parameter is relatively less robust than the first at least one parameter, and the second information augments the first information when combined with the first information. The wireless communication device then transmits the first transmission stream and the second transmission stream to at least one other wireless communication device. Examples of such parameters include forward error correction (FEC) code, error correction code (ECC), modulation coding set (MCS), modulation type including a mapping of constellation points arranged in a constellation, power (e.g., transmit (TX) power), orthogonal frequency division multiplexing (OFDM) configuration, and/or a multiple-input-multiple-output (MIMO) configuration.

A user equipment in a radio communication system including a base station and the user equipment, including: a configuration information management unit configured to hold configuration information indicating a protection resource that is a resource that is protected from puncturing that may occur in an assigned resource that is a resource assigned by the base station; and a reception unit configured to receive, from the base station, control information indicating that puncturing occurs in the assigned resource, and receive, from the base station, a predetermined signal using the protection resource based on the configuration information.

In a method for transmitting video for a display panel between a transmitter in electronic communication with a receiver over a wireless communication channel, the method includes: receiving, by a transmitter, a frame of video data from a data source; reorganizing, by the transmitter, the frame of video data into a plurality of packets according to levels of importance of bits of the frame of video data; generating, by the transmitter, a tag for each of the packets, the tags corresponding to different relatively levels of importance of the packets; performing, by the transmitter, different protection techniques for each of the packets based on the tag corresponding to each of the packets; and transmitting, by the transmitter, the packets and the tags to the receiver for display on the display panel such that each packet is transmitted according to the different protection techniques based on their corresponding tagging.

Embodiments of the present disclosure relate to a communication method and a communication device. There is provided a communication method implemented at a first device. The method comprises: determining quantities of information of units in control information; mapping, based on the quantities of information of the units and reliabilities of subchannels for carrying the control information, the units to a subchannels; and transmitting the control information to a second device via the subchannel. There is also provided a communication method implemented at a second device, as well as corresponding first device and second device.

By bearing multiple service signals in a same bearing area of a same Ethernet PCS channel, it is implemented that multiple types of service signals share an Ethernet channel, so that the multiple types of service signals can share a link resource and an interface module resource. This provides a basis for convergence and integration of devices in a multi-technology system, and can improve utilization of link resources and reduce a quantity, a footprint, power consumption, maintenance costs, and the like of devices in a metropolitan area network.

Apparatuses, methods, and systems are disclosed for video codec aware RAN configuration and unequal error protection coding. An apparatus includes a processor that detects a video coded traffic stream and a video codec specification used to encode the video coded traffic stream, determines an awareness of video coded traffic application data units (ADUs) of the video coded traffic stream as video coded network abstraction layer (NAL) units of data, aligns the video coded NAL units of the video coded traffic stream to physical layer (PHY) transport elements and subsequent channel coding element partitions for a video coded traffic aware PHY transport, determines a channel coding rate allocation of the channel coding element partitions, and applies a forward error correction (FEC) coding given at least the determined channel coding rate allocation of the video coded traffic aware PHY transport to channel coding element partitions for protection against radio transmission errors.

A control device for use in a broadcast system includes a broadcast controller that controls a broadcast transmitter of the broadcast system that broadcasts broadcast signals in a coverage area for reception by terminals including a broadcast receiver and a broadband receiver, and a broadband controller that controls a broadband server of a broadband system that provides redundancy data to terminals within the coverage area. The broadband controller is configured to control the provision of redundancy data by the broadband server for use by one or more terminals which use the redundancy data together with broadcast signals received via said broadcast system for recovering content received within the broadcast signals and/or provided via the broadband system.

Systems and methods for reducing communication latency are provided. A communication session with a remote device is initiated. One or more message packets are transmitted to the remote device. Subsequently, it is determined whether any additional message packet is scheduled to be transmitted to the remote device. In the event that no additional message packet is scheduled to be sent to the remote device, a loss detection packet is appended to a last message packet. The last message packet and the loss detection packet are transmitted to the remote device. It is further determined whether the last message packet was successfully received by the remote device based on receipt of an acknowledgment message. In the event that the last message packet was not successfully transmitted, a retransmit of the last message packet is executed.

Embodiments of this application provide a data transmission method and device, so as to increase an uplink/downlink data transmission throughput. The method includes: splitting a to-be-transmitted transport block into N code blocks with incompletely equal sizes, where N is an integer greater than or equal to 2; performing error correction coding on the N code blocks to obtain N encoded bit blocks; and non-orthogonally transmitting the N encoded bit blocks by using resources that are the same in at least one dimension of a time domain, a frequency domain, a space domain, and a code domain.

Disclosed herein is method and device for performing a Hybrid Automatic Repeat request (HARQ) based on polar codes in a wireless communication system. A transmitter transmits a first packet to a receiver. The transmitter receives a re-transmission request for the first packet from the receiver. The transmitter transmits a second packet to the receiver. Herein, each of the first packet and the second packet includes at least one information bit and at least one frozen bit. An information bit having a smallest mutual information corresponding to a bit channel within the first packet is re-transmitted through a first bit channel capable of transmitting at least one information bit included in the second packet. Alternatively, a new information bit is transmitted through a second bit channel capable of transmitting at least one information bit included in the second packet.
