    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling from a network entity, such as radio resource control (RRC) signaling, indicating for the UE to select a mixed-waveform modulation and coding scheme (MCS) table. The UE may select the MCS table in accordance with the signaling. The network entity may send additional control signaling to the UE indicating for the UE to use one or more of the waveforms in the mixed-waveform MCS table for scheduled data. For example, the UE may transmit the scheduled data, receive the scheduled data, or both in accordance with the one or more waveforms indicated in the additional control signaling.

    Abstract: Aspects relate to random access messaging. A base station may transmit a first random access message (e.g., a random access channel (RACH) Msg2) to a user equipment. The first random access message may include an indication of at least one beam that the user equipment may use to transmit a second random access message (e.g., a RACH Msg3). The user equipment may then transmit the second random access message using a beam selected from the indicated at least one beam.

    Abstract: This disclosure provides systems, methods, and apparatuses for a wireless node to receive a phase tracking reference signal (PTRS) transmitted inside a downlink random access channel (RACH) message. The wireless node may receive a downlink RACH message that includes a PTRS based on an indication received in a downlink RACH message or a physical downlink control channel (PDCCH) associated with a downlink RACH message. In some aspects, the wireless node may utilize the PTRS for phase error correction or frequency error correction (such as frequency error caused by Doppler effects). This disclosure also provides systems, methods, and apparatuses for a component of a base station to provide an indication that a PTRS is included in a downlink RACH message. The indication may be provided in a downlink RACH message or a PDCCH associated with a downlink RACH message.

    Abstract: Methods, apparatuses, and computer readable medium for PRACH repetition and Msg 3 repetition are provided. An example method may include receiving, from a base station, an indication associated with a set of PRACH resources. The example method may further include transmitting, to the base station, one or more PRACH repetitions using the set of PRACH resources. The example method may further include receiving, from the base station based on the one or more PRACH repetitions, a grant associated with a PUSCH repetition.

    Abstract: An interference metric measured at a specific antenna may differ from interference metrics at different antennas. As a result, any actions based on the interference metric may unduly be influenced by such difference. In some implementations, an apparatus or device reports an overall interference metric that accounts for spatial variations in interference metrics at different antennas. An example method includes measuring, by a user equipment, an interference metric at each antenna of two or more antennas for wireless signals transmitted by a base station, generating an overall interference metric based on the interference metrics for the two or more antennas, and transmitting, by the user equipment, the overall interference metric to the base station.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish communications between the UE and a serving cell. The serving cell may be different than each non-serving cell of a set of non-serving cells for the UE. The UE may use machine learning models to determine outputs associated with mobility measurement reporting for the UE. The outputs may indicate whether to perform measurements associated with the set of non-serving cells, whether to report the measurements associated with the set of non-serving cells, one or more non-serving cells within the set of non-serving cells for performing or reporting the measurements, or one or more reference signals of the one or more non-serving cells for performing the measurements, or any combination thereof. The UE may perform the mobility measurement reporting based on the outputs.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station in a wireless communications system. The UE may perform a random access procedure to communicate with the base station. The base station may configure the UE with criteria for selecting a transmission mode. The UE may select a transmission mode for transmitting repetitions of physical random access channel (PRACH) transmissions according to current conditions satisfying the criteria. The criteria may be different based on a contention free random access (CFRA) procedure type or a purpose of the CFRA procedure. The transmission modes may include repetitions of PRACH on multiple random access channel (RACH) occasions, multiple component carriers (CCs), multiple frequency allocations of a same CC, superposition of preambles, different RACH resources, or different PRACH formats.

    Abstract: Methods, systems, and devices for wireless communications are described. The techniques described herein support dynamically indicating uplink control channel repetition multiple different types of uplink signaling. A user equipment (UE) may receive first control signaling indicating a first repetition factor for transmission of a feedback message associated with a beam or transmission configuration indicator (TCI) state. The UE may receive second control signaling scheduling transmission of a control message associated with the beam or TCI state. The UE may transmit, in accordance with a second repetition factor, the control message based at least in part on both the feedback message and the control message being associated with the beam. In some cases, the second repetition factor may be configured with the second control signaling.
