A wireless transmitter and antenna are provided on the transmit side, and a receiver and an antenna are provided on the receive side. A transmitter receives samples from a video source via media signals, permutes the input samples into input vectors, and encodes each input vector with reference to a set of orthogonal codes to produce analog SSVT signals per encoder. The wireless transmitter modulates the SSVT signals generated by the SSVT transmitter onto one or more carrier frequency signals. Once modulated, the carrier frequency signals are then broadcast by the antenna. On the receive side, the antenna receives the broadcast and provides the modulated carrier signals to the wireless receiver. In response, the wireless receiver demodulates the carrier frequency signals and produces the corresponding analog SSVT signals, which are then decoded into reconstructions of the input media samples into output vectors, which are then permuted into output samples that are sent to a video sink for display.

A wireless device is configured to produce a signal in a time slot of a frame, wherein the time slots have variable lengths. The signal having a first portion and a second portion, wherein the first portion and the second portion are located in defined time regions in the slot. Further, the first portion having data and a multiplexed first pilot, wherein the multiplexed first pilot is derived from a pseudo random sequence, the second portion having a pilot sequence and a cyclic prefix. The wireless device transmits the produced signal in the time slot.

A multi-codeword transmission method and apparatus is provided that allows a terminal device to correctly demodulate data in a multi-codeword transmission scenario. The method includes generating, by a network device, downlink control information corresponding to each of a plurality of codewords to be transmitted to a terminal device. The downlink control information corresponding to each codeword includes at least one of a physical downlink shared channel resource element mapping, a quasi-co-location indicator, one or more antenna ports, a scrambling identifier, and a number of layers. The method further includes transmitting, by the network device, the downlink control information corresponding to the plurality of codewords to the terminal device.

The disclosed techniques allow for transmitting a signal stream from a sender to a receiver in an environment including multiple senders and receivers. The technique for the sender decomposes a data stream from the sender into multiple substreams, encodes a substream by a codeword, further superimposes multiple codewords to form a signal stream in an asynchronous manner, and transmits the signal stream to the receiver. A codeword can span over multiple blocks. The receiver receives a first codeword stream from a first sender, receives a second codeword stream from a second sender, the two codeword streams may be received at the same time as one signal, and decodes the first codeword stream and second codeword stream over a sliding window of multiple blocks.

There are provided techniques for transmitting, receiving and coordinating pilot sequences, and for evaluating channel properties. A pilot signal may comprise a pilot sequence, which comprises a plurality of symbols with:at least one first set of equally spaced symbols, andat least one second set of equally spaced symbols, the symbols of the at least one second set of equally spaced symbols being inserted in between the symbols of the at least one first set of equally spaced symbols,It is possible to select:the at least one first set of equally spaced symbols in such a way that each first set of equally spaced symbols represents a respective first code andthe at least one second set of equally spaced symbols in such a way that each second set of equally spaced symbols represents a respective second code.each first code and each second code may be selected from a set of codes in which each code of the set of codes is orthogonal to at least one other code of the set of codes. the same technique may be implemented at another transmitter, which transmits sequences using codes orthogonal to the codes transmitted by the transmitter.

An apparatus configured to: determine sequences available for transmitting uplink control information; determine a reference payload size; divide the sequences available for transmitting the uplink control information into a plurality of subsets based, at least partially, on the reference payload size; and determine at least one sequence for transmitting the uplink control information within at least one subset of the plurality of subsets.

The present application provides a data transmission method, an electronic device, and a computer-readable medium. The data transmission method comprises: performing an orthogonal spreading code transform on data included in an edge group of first sequences in N groups of first sequences obtained by dividing a first data sequence to be transmitted, to obtain N groups of second sequences, wherein N is an integer greater than or equal to 2; performing a first Fourier transform on the N groups of second sequences to obtain N groups of third sequences; performing a second Fourier transform on the N groups of third sequences to obtain a second data sequence; and transmitting the second data sequence.
