This disclosure describes a first slave device that transmits information to a second slave device indicating that a first data packet was improperly received from a master device, so that a corresponding data packet may be relayed from the second slave device to the first slave device. In an aspect, the second slave device may receive a first data packet followed by an indication that the first slave device improperly received the first data packet, where the second slave device is configured to relay the first data packet to the first slave device in response thereto. In another aspect, the second slave device may receive a request to listen for a separate data stream of the first slave device based on a first data packet being improperly received by the first slave device and transmit a second data packet of the separate data stream to the first slave device.

The present disclosure describes method, systems, and devices for transmitting feedback information by a communication node. The method includes sending a hybrid automated repeat request-acknowledgement (HARQ-ACK) in response to a preset rule being satisfied.

Methods, systems, and devices for wireless communications are described. A base station may configure an outer coded block which a user equipment (UE) may implement to recover an unsuccessfully decoded transmission. The base station may send, to the UE, downlink control information (DCI) indicating an outer coding scheme for the group of data blocks (e.g., a first data block and a second data block). The UE may monitor for the data blocks and the outer coded block. The UE may decode the data blocks based on the outer coded block and the outer coding scheme. In some examples, the outer code block may be made up of a combination of the first and second data blocks. The UE may use the combination of the outer coded block and one of the data blocks to decode an unsuccessfully decode data block.

The present invention relates to method of transmitting and receiving signals and a corresponding apparatus. One aspect of the present invention relates to a method of receiving a signal, which includes an L1 signaling region where the L1 signaling has an adaptive L1 block structure for increased spectrum efficiency in a channel bonding environment.

The present invention provides a method of transmitting broadcast signals. The method includes, formatting input streams into Data Pipe (DP) data, Low-Density Parity-Check (LDPC) encoding the DP data according to a code rate, bit interleaving the LDPC encoded DP data, mapping the hit interleaved DP data onto constellations, building at least one signal frame including the mapped DP data, and modulating data in the built signal frame by an Orthogonal Frequency Division Multiplexing (OFDM) method and transmitting the broadcast signals having the modulated data, wherein the input streams include Audio/Video (A/V) data and service guide data, and wherein the Audio/Video (A/V) data and service guide data are included in first ISO base media file format (ISOBMFF) files.

A receiver for receiving data in a broadcast system includes a broadcast receiver configured to receive, via the broadcast system, a receiver input data stream including a plurality of channel symbols represented by constellation points in a constellation diagram. A demodulator demodulates the channel symbols into codewords and a decoder decodes the codewords into output data words. A redundancy unit selects or requests, if demodulation of a channel symbol and/or decoding of a codeword is erroneous or likely to fail, redundancy data for demodulation of future channel symbols and/or decoding of future codewords via a broadband system and a broadband receiver obtains the redundancy data via the broadband system. The demodulator and/or the decoder is configured to use the obtained redundancy data to demodulate the respective future channel symbols and to decode the respective future codewords, respectively.

A base station transmits and a UE detects broadcast information when the UE operates in a Coverage Enhancement (CE) mode. The base station transmits repetitions of signaling conveying broadcast information in one or more subframes of each frame in a quadruple of frames. The transmission is intermittent in time. To detect the broadcast information, the UE blindly combines and decodes the repetitions of signaling assuming their existence. The base station informs the pattern for the intermittent transmissions of the signaling to UEs connected to the base station or to other base stations.

A wireless communication device and a wireless communication method. The wireless communication device includes one or more processors. The processor is configured to estimate an equivalent channel from a base station to user equipment based on a user equipment specific reference signal from the base station, and generate, according to the estimated equivalent channel, a channel state indication used to be fed back to the base station.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first transmission including encoded bits of a data packet and a second transmission including some or all of the encoded bits of the data packet. The first transmission associated with a first limited buffer rate matching (LBRM) configuration and the second transmission may be associated with a second LBRM configuration. The UE may process the first transmission and the second transmission based on the first LBRM associated with the first transmission being different than the second LBRM associated with the second transmission.

A wireless communication device that communicates with a plurality of slave units, including: a transmitter that transmits a data transmission instruction including a first identification information of a single slave unit among the plurality of slave units; a receiver that receives data corresponding to the data transmission instruction from the single slave unit; wherein the transmitter transmits to the plurality of slave units acknowledgment data which has incorporated second identification information into an acknowledgment to the data received from the single slave unit, the second identification information indicating another slave unit which transmits data corresponding to a next data transmission instruction to the wireless communication device.
