Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a synchronization signal block (SSB) from a plurality of SSBs received from a base station based at least in part on a power measurement associated with the SSB. The UE may determine a physical random access channel (PRACH) coverage enhancement (CE) level that is associated with the SSB. The UE may perform, with the base station, a PRACH transmission on PRACH resources associated with the SSB and the PRACH CE level. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform an operation to obtain one or more channel state information (CSI) resources (e.g., new resources) from a set of resources indicated by a CSI report configuration. For example, the UE may aggregate or separate respective resources of the set of resources to obtain one or more CSI resources. The operation may be performed based on a first number of antenna ports associated with each resource of the set of resources and a second number of antenna ports associated with a codebook configuration. Thus, performing the operation may result in the UE forming one or more CSI resources for measuring CSI on the one or more CSI resources. The UE may transmit a CSI report based on measuring the CSI for a set of reference signals received on the one or more CSI resources.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may output a channel state information (CSI) report message that indicates multiple codebook configurations. A UE may receive the CSI report message indicating a set of codebook configurations associated with a set of antenna port configurations. The UE may transmit a CSI report indicating one or more codebook configurations of the set of codebook configurations, where CSI included in the CSI report is based on the one or more codebook configurations. The UE may then communicate with a network entity based on the channel state information report indicating the one or more codebook configurations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information indicating at least one of a first set of peak reduction tones (PRTs) for uplink communication, or a second set of PRTs for downlink communication, for use in a full-duplex communication mode. The first set of PRTs and the second set of PRTs may share at least one PRT. The UE may transmit, to the base station, or receive, from the base station, at least one signal based at least in part on the at least one of the first set of PRTs or the second set of PRTs. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify physical uplink shared channel (PUSCH) configuration parameters to send a handover completion message at the end of a handover. A source cell may notify the UE of a handover via a handover command and the UE may acquire system information, and in some cases, a downlink message, from a target cell. The UE may identify a waveform configuration, numerology configuration, and/or modulation scheme using information from the handover command message, the system information, and/or the downlink message. The UE may also determine occasions for transmitting a PUSCH. For example, each occasion may include a set of time-frequency resources on which the PUSCH may be transmitted. The UE may send the handover completion message to the target cell via the PUSCH, during the one or more identified occasions, using the identified configuration parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a resource allocation indicating a plurality of transmission tones comprising a subset of data tones of a plurality of data tones and a subset of peak reduction tones (PRTs) of a plurality of PRTs, wherein the resource allocation indicates a plurality of data tone locations and a plurality of PRT locations within a particular bandwidth, wherein a subset of PRT locations of the plurality of PRT locations are arranged relative to a subset of data tone locations of the plurality of data tone locations according to a PRT sequence corresponding to a set of allocated frequency resources; and transmit a data transmission using a waveform based at least in part on the resource allocation. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may be configured to transmit two or more consecutive transmissions that may be used for demodulation reference signal (DMRS) bundling. If criteria for DMRS bundling are not satisfied, the UE may generate dummy data to transmit during the skipped configured grant occasion, and may maintain phase continuity across the skipped configured grant occasion and any other PUSCHs in a set of uplink transmissions. In some examples, the UE may deprioritize DMRS bundling for sets of PUSCHs during which a PUSCH is to be skipped. If criteria for DMRS bundling are not satisfied, the UE may not maintain phase continuity across the set of PUSCHs, and may refrain from transmitting any data during the CG-PUSCH occasion.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message from a base station indicating a configuration of an uplink waveform for full-duplex communications at the UE. The UE may receive an additional control message scheduling a set of uplink resources and a set of downlink resources for the full-duplex communications. The set of uplink resources and the set of downlink resources may at least partially overlap in a time-domain. A frequency-domain gap between the set of uplink resources and the set of downlink resources may be based on the first uplink waveform and a first downlink waveform used by the base station. The UE may communicate with the base station on the set of uplink resources and the set of downlink resources in accordance with the frequency-domain gap.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for managing uplink power control in accordance with priority-specific beta factors. An example method for wireless communication performed by a user equipment (UE) generally includes determining a value of a beta factor based on a priority level of uplink control information (UCI) to be transmitted on a physical uplink shared channel (PUSCH); and transmitting the UCI on the PUSCH with transmit power determined based, at least in part, on the value of beta factor. Another example method performed by a UE generally includes deciding, when the UE is configured to perform demodulation reference signal (DMRS) bundling across PUSCH repetitions, whether to prioritize the DMRS bundling or transmission of UCI multiplexed in one of the PUSCH repetitions; and transmitting the PUSCH repetition with the multiplexed UCI in accordance with the decision.
