Abstract: An Orthogonal Time Frequency Space Modulation (OTFS) modulation scheme achieving multiple access by multiplexing multiple signals at the transmitter-side performs allocation of transmission resources to a first signal and a second signal, combining and converting to a transmission format via OTFS modulation and transmitting the signal over a communication channel. At the receiver, multiplexed signals are recovered using orthogonality property of the basis functions used for the multiplexing at the transmitter.

Abstract: A transmitting device may generate a plurality of CBs. The plurality of CBs may be grouped into a plurality of CBGs. The transmitting device may interleave the plurality of CBs across the plurality of CBGs to construct a channel. The transmitting device may map the channel to one or more time-frequency resources associated with an allocation. The transmitting device may transmit, for a receiving device, the mapped channel using the one or more time-frequency resources. The receiving device may recover a plurality of CBs from the channel. The receiving device may deinterleave the plurality of CBs to recover a plurality of CBGs. The receiving device may decode the deinterleaved plurality of CBs based on the recovered plurality of CBGs.

Abstract: In a transmission method according to one aspect of the present disclosure, a encoder performs error correction coding on an information bit string to generate a code word. A mapper modulates a first bit string in which the number of bits is the predetermined integral multiple of (X+Y) in the code word using a first scheme, the first scheme being a set of a modulation scheme in which an X-bit bit string is mapped to generate a first complex signal and a modulation scheme in which a Y-bit bit string is mapped to generate a second complex signal, and modulates a second bit string in which the first bit string is removed from the code word using a second scheme different from the first scheme.

The data transmission method includes: A first module obtains at least one channel of first data encoded based on first FEC; converts the at least one channel of first data to obtain at least one channel of second data, where a sum of rates of the at least one channel of second data is not less than a sum of rates of the at least one channel of first data; and transmits the obtained at least one channel of second data. In the method, the at least one channel of first data is converted to obtain the at least one channel of second data whose sum of rates is not less than the sum of rates of the at least one channel of first data.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) or a base station, or both, may determine a configuration for partitioning a set of sequences into multiple sequence pools associated with multiple UEs. The UE or the base station, or both, may determine a sequence pool associated with the UE based on the configuration, which may include parameters or instructions for determining the sequence pool associated with the UE. The UE or the base station, or both, may select a subset of sequences from the sequence pool associated with the UE and construct a codebook including the subset of sequences. The UE may select a sequence from the constructed codebook based on a quantity of bits of a payload and may transmit the payload to the base station using the selected sequence.

Abstract: An encoder outputs a first bit sequence having N bits. A mapper generates a first complex signal s1 and a second complex signal s2 with use of bit sequence having X+Y bits included in an input second bit sequence, where X indicates the number of bits used to generate the first complex signal s1 , and Y indicates the number of bits used to generate the second complex signal s2 . A bit length adjuster is provided after the encoder, and performs bit length adjustment on the first bit sequence such that the second bit sequence has a bit length that is a multiple of X+Y, and outputs the first bit sequence after the bit length adjustment as the second bit sequence. As a result, a problem between a codeword length of a block code and the number of bits necessary to perform mapping by a set of modulation schemes is solved.
