Abstract: A base station and a user equipment (UE) may perform a dynamic waveform switching for physical uplink shared channel (PUSCH) transmissions. The base station may send a configuration for dedicated waveform switching associated with the PUSCH transmissions, and transmit, to the UE, an indication of a first waveform for transmitting the PUSCH, the indication being independent of the bandwidth part (BWP) configuration for the PUSCH. Based on the configuration for the dedicated waveform switching associated with the PUSCH transmissions and the indication of the first waveform for the PUSCH transmission, the UE may transmit the PUSCH, at least one PUSCH repetition, and at least one retransmission of the PUSCH, and the base station may receive the PUSCH, at least one PUSCH repetition, and at least one retransmission of the PUSCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information that configures one or more sounding reference signal (SRS) resource sets that includes one or more SRS resources associated with a full duplex (FD) set of symbols and one or more SRS resources associated with a non-FD set of symbols. The UE may receive at least one of a radio resource control communication or a downlink control information communication indicating at least one of the one or more SRS resources that are to be used for an uplink transmission repetition. The UE may transmit the uplink transmission repetition in one of: only the FD set of symbols, only the non-FD set of symbols, or both the FD set of symbols and the non-FD set of symbols. Numerous other aspects are described.

Abstract: Various aspects relate generally to sounding reference signal (SRS) reference indicators (SRIs) indicating an SRS associated with a transmission configuration to use for transmission of a data channel communication. Some aspects more specifically relate to an SRI indicating an SRS from an SRS resource having a same duplexing type as a slot in which the data channel communication is scheduled. In some aspects, the SRI may indicate an SRS from an SRS resource that is not a most-recent SRS resource based on the most-recent SRS resource having a different duplexing type than the slot in which the data channel communication is scheduled.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a network entity may transmit, and a user equipment (UE) may receive, for generation of a demodulation reference signal sequence corresponding to a resource block allocation, control signaling indicative of a selection of a root number and a prime number. The prime number is one of two or more prime numbers used to generate a set of demodulation reference signal sequences for the resource block allocation. The UE may generate, using the prime number and the root number as input into a sequence generation function, the demodulation reference signal sequence of the set of demodulation reference signal sequences corresponding to the resource block allocation and transmit a physical uplink shared channel transmission including the demodulation reference signal sequence.

Abstract: A method for wireless communication at a UE and related apparatus are provided. In the method, the UE first transmits, to a network entity, RF information indicating coupling states of multiple bands of the UE based on an RF exposure of the multiple bands. The UE then communicates, after providing the RF information indicating the coupling states, with the network entity through one or more of the multiple bands.

Abstract: A base station performs joint channel estimation for a set of physical uplink shared channels (PUSCHs) with bundled DMRS from a user equipment (UE). The UE receives an indication to transmit the set of PUSCHs, each PUSCH of the set of PUSCHs comprising a corresponding DMRS from the base station. The base station transmits, and the UE receives, a sounding reference signal resource indicator for each PUSCH of the set of PUSCHs. The UE transmits the PUSCHs based on a same sounding reference single resource, the SRI for a first PUSCH of the set of PUSCHs indicating the same SRS resource.

Abstract: Aspects of the disclosure provide techniques for waveform indication for physical uplink control channel (PUCCH) transmissions. A network entity may provide an indication of a waveform type, such as CP-OFDM, DFT-s-OFDM, or other suitable waveform type, for a PUCCH format to a user equipment (UE). The UE may then communicate a PUCCH with the network entity using the waveform type for the PUCCH format.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adjust resources (e.g., time resources, frequency resources) used to transmit repetitions of uplink control information (UCI) over a physical uplink control channel (PUCCH). The UE may adjust two parameters corresponding to different scales (e.g., levels) of adjustment, where a first parameter corresponds to a number of repetitions of a PUCCH resource and a second parameter corresponds to a number of slots within each PUCCH repetition. The UE may adjust the resources based on the first parameter, the second parameter, a size of UCI, a maximum coding rate, or some combination thereof, such that the PUCCH resources carrying UCI satisfy the maximum code rate and UCI size.
