A transmitting apparatus is disclosed. The transmitting apparatus includes an encoder to perform channel encoding with respect to bits and generate a codeword, an interleaver to interleave the codeword, and a modulator to map the interleaved codeword onto a non-uniform constellation according to a modulation scheme, and the constellation may include constellation points defined based on various tables according to the modulation scheme.

The present disclosure provides a terminal device that allows constraints on user allocation to be prevented and spread codes to be allocated in a scheduler when non-adaptive HARQ is employed using a PHICH. A codeword generator generates code words by encoding data, a layer mapping unit places each CW in one or a plurality of layers, a DMRS generator generates a reference signal for each layer in which a CW is placed by using any resource among a plurality of resources defined by a mutually orthogonal plurality of OCCs, and an ACK/NACK demodulator receives a response signal indicating a retransmission request. When a response signal requesting retransmission of only a CW placed in a plurality of layers is received, the DMRS generator uses each resource having the same OCC among the plurality of resources for the reference signals generated in the corresponding layers.

A terminal according to one aspect of the present disclosure includes a control section that assumes that, in a case where time domain orthogonal cover code (TD-OCC) is configured for consecutive symbols of a sounding reference signal (SRS), the same sequence is configured to the consecutive symbols of the SRS, and a transmitting and/or receiving section that performs at least one of transmission processing and reception processing of the SRS, based on the TD-OCC. According to one aspect of the present disclosure, reduction in SRS capacity can be suppressed.

An apparatus (e.g., a user equipment (UE)) maps a plurality of mutually orthogonal sequences to each of a plurality of physical resource blocks (PRBs) within an interlace. The apparatus then performs a physical uplink control channel (PUCCH) transmission in a New Radio unlicensed spectrum (NR-U). The apparatus also receives an assignment of a set of sequences for each PRB of the plurality of PRBs from a wireless network. In response, the apparatus performs an uplink control information (UCI) transmission via the PUCCH in the NR-U.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink communication that includes one or more codepoints indicating a plurality of transmit precoder matrix indicator (TPMI) indices and/or a sounding reference signal (SRS) resource indicator (SRI) codepoint indicating one or more SRS resources. The UE may identify, based at least in part on the one or more codepoints, one or more TPMI indices, of the plurality of TPMI indices, for one or more repetitions of a codebook-based PUSCH transmission and/or may identify, based at least in part on the SRI codepoint, one or more SRS resources for the one or more repetitions. Numerous other aspects are provided.
