This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for a user equipment (UE) and a base station (BS) to determine channel state information (CSI) processing unit (CPU) occupancy of the UE. The UE and the BS may determine that at least one CPU from a CPU pool is occupied by an uplink CSI request from a CSI reference signal (CSI-RS) to at least a CSI request occasion. The UE and the BS may determine a number of occupied CPUs, for example, based on an accumulated or aggregated number of occupied CPUs for multiple CSI operations. The UE may perform a number of CSI operations based on the determined number of occupied CPUs. The BS may configure the UE to perform the number of CSI operations, for example, by transmitting one or more of a configuration, activation, or scheduling message.

Methods, systems, and devices for wireless communications are described herein for power boosting uplink share channel repetitions. A user equipment (UE) may receive from abase station a control message that schedules a set of transmission occasions for one or more uplink messages for the UE. The UE may determine from the control message the set of transmission occasions to apply power boosting. The UE may determine the transmit power for each transmission occasion based at least in part on the power boost configuration. The UE may transmit one or more uplink messages via the set of transmission occasions with the determined transmit power.

Methods, systems, and devices for sounding reference signal (SRS) resource indicator (SRI) association for configured grant (CG) based transmission and reception point (TRP) physical uplink shared channel (PUSCH) transmission are described. In some examples, a user equipment (UE) may receive first control signaling indicating a first and second sounding reference signal (SRS) resource set associated with a first and second set of power control parameter, respectively. The UE may receive second control signaling indicating a CG configuration, the first and second power control parameters for transmissions in the CG configuration. In some examples, the UE may determine a configuration status for one or more fields the first control signaling, the second control signaling, or both. The UE may select an SRS resource set based on the configuration status and may transmit one or more CG uplink transmissions with the CG configuration using the selected SRS resource set.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor a set of downlink control channel candidates that are associated with each other, the set of downlink control channel candidates including a first downlink control channel candidate in a first transmission time interval (TTI) and a last downlink control channel candidate in a second TTI subsequent to the first TTI. The UE may receive, based on the monitoring, at least one repetition of downlink control information (DCI) within one of the first downlink control channel candidate or the last downlink control channel candidate, the DCI scheduling a transmission between a base station and the UE. The UE may apply a scheduling offset associated with the transmission based on a timing of the last downlink control channel candidate, and may subsequently communicate with the base station via the transmission based on the scheduling offset.

Techniques for timing relationships for physical downlink control channel repetition

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive at least one downlink control information message that schedules multiple sets of repetitions of a physical uplink shared channel transmission with different sets of transmission parameters. The scheduled repetitions of the multiple sets of repetitions may be transmitted consecutively. The UE may transmit one or more of the scheduled repetitions of the multiple sets of repetitions using one or more time gaps between the scheduled repetitions of the multiple sets of repetitions. Numerous other aspects are provided.

Time gaps between physical uplink shared channel repetitions

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a channel state information (CSI) report configuration that includes configuration information associated with multiple CSI reports. The UE may generate a CSI report message in which the multiple CSI reports are separately encoded and ordered based at least in part on one or more rules. In some aspects, the CSI report message may be generated for transmission on one or more of a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH). Numerous other aspects are provided.

The apparatus receives an activation command activating at least one of one or more downlink TCI states, or one or more uplink TCI states. The apparatus applies at least one of the one or more downlink TCI states or the one or more uplink TCI states based on the activation command and a condition for separate downlink/uplink unified TCI.

Methods, systems, and devices for wireless communication are described. A network entity may transmit control signaling to a user equipment (UE) to schedule a downlink message and a set of uplink signals for conveying feedback in response to the downlink message. The downlink message may include a first portion with information for the UE and a second portion with information for the UE and at least one other UE based on a rate splitting procedure. The UE may transmit uplink signaling that indicates one or more UE capabilities, communication parameters, or both. The network entity may determine a time period between a final symbol of the downlink message and a first symbol of the set of uplink symbols, one or more parameters to apply for transmission of the downlink message, or a data rate for the downlink message based on the UE capabilities and parameters reported by the UE.

This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for a user equipment (UE) to receive a configuration for a plurality of groups of sounding reference signal (SRS) ports associated with an SRS resource, the configuration indicating one or more cyclic shift parameters for each group of SRS ports of the plurality of groups of SRS ports. The UE also can transmit one or more SRSs using at least one group of SRS ports of the plurality of groups of SRS ports based at least in part on the one or more cyclic shift parameters associated with the at least one group of SRS ports.

Methods, systems, and devices for wireless communications are described. For instance, a network entity may transmit, to a user equipment Transmission (UE), control signaling indicating that the UE is to provide feedback corresponding to a set of feedback process identifiers for at least one component carrier. The network entity may transmit, to the UE, a cancellation indication Feedback Message that cancels a scheduled uplink transmission in which the UE is scheduled to provide feedback data corresponding to a subset of the set of feedback process identifiers. The network entity may transmit, to the UE, a control message scheduling the UE to transmit the feedback data corresponding to the subset of the set of feedback process identifiers (e.g., based on the cancellation indication). The UE may transmit, to the network entity, a feedback message including the feedback data for the subset based on the control message.
