Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE transmits, to a network entity via a first beam, a maximum permissible exposure (MPE) report indicating a second beam. The UE then receives a response indicating an acknowledgment of the MPE report from the network entity. The UE then transmits an uplink (UL) transmission using the second beam to the network entity.

Uplink (UL) beam reset after maximum permissible exposure (MPE) report

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that a multi-panel uplink transmission is to be performed by the UE, the multi-panel uplink transmission using at least a first transmit panel and a second transmit panel of the UE. The UE may identify a priority order for performing uplink transmissions of the multi-panel uplink transmission from the UE, the priority order including priority levels associated with the first transmit panel and the second transmit panel. The UE may identify an available transmit power for the multi-panel uplink transmission. The UE may perform, according to the priority order, the multi-panel uplink transmission using at least the first transmit panel at a first transmit power and the second transmit panel at a second transmit power, the first transmit power and the second transmit power based at least in part on the available transmit power.

Transmit power prioritization for multi-panel uplink transmission

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine an association between multiple phase tracking reference signal (PTRS) ports and multiple codewords that are to be used for an uplink communication that uses multiple antenna port groups, and transmit the uplink communication using the multiple codewords based at least in part on the association. Numerous other aspects are provided.

Configuration for phase tracking reference signal ports to enable uplink transmission with multiple codewords

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.

Channel state information (CSI) processing unit (CPU) occupancy for user equipment (UE) initiated CSI requests

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.

Power boosting for uplink shared channel repetitions

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, from a base station, downlink control information (DCI) in format 1_2 that includes an indicator with a first quantity of codepoints that is smaller than a second quantity of activated transmission configuration indicator (TCI) states. Accordingly, the UE may apply a TCI state, from the first quantity of activated TCI states out of the second quantity of activated TCI states, according to the indicator. Numerous other aspects are described.

Transmission configuration indicator states in downlink control information format 1_2

A UE may receive, from a base station, information indicating a set of beams associated with a plurality of CCs. The UE may be configured to activate the set of beams on the plurality of CCs either for a single TRP or for multiple TRPs, with the set of beams being activated for the single TRP when less than two beam IDs respectively associated with the set of beams are mapped to a codepoint and less than two pool indexes are configured for a CORESET associated with at least one CC of the plurality of CCs. The set of beams may be activated for the multiple TRPs when at least one of: the codepoint is mapped to two or more beam IDs, or the CORESET either is configured with two or more pool indexes or is not configured with a pool index.

Beam update procedure with component carrier configuration

Various aspects relate to scheduling reference signals across multiple carriers (e.g., across cells). Signaling may be used to indicate whether reference signals are scheduled across multiple carriers. For example, a single instance of downlink control information (e.g., the downlink control information sent via a single time slot) that schedules multiple carriers (e.g., multiple component carriers) may include an indication of whether reference signals are scheduled for two or more of the scheduled carriers.

Scheduling reference signals for multiple carriers

Certain aspects of the present disclosure provide techniques for power prioritization including physical random access channel (PRACH) on candidate cells. An example method, performed at a user equipment (UE), includes allocating transmit power for a transmission of a signal to a candidate cell based on a power prioritization rule that considers UE transmit power for transmissions on the candidate cell and at least one other cell, and transmitting the signal to the candidate cell according to the allocation.

Power prioritization including candidate cells

Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may communicate with a multiple transmission and reception points (TRPs) associated with a base station using multiple panels and each panel of the UE may be associated with a different timing advance value Signaling of multiple timing advance values from the base station to the UE may be associated with large overhead. In some implementations of the present disclosure, the base station and the UE may support methods and algorithms for deriving multiple timing advance values from a single timing advance value. For example, the base station may transmit a timing advance value to the UE and the UE may derive a timing advance value for each panel of the UE based on the received timing advance value and a timing of downlink signals received at each of the panels of the UE.

Timing advance indication for multi-panel uplink transmission

An example method includes requesting an adjustment to SMTC. The example method further includes performing radio resource management (RRM) measurements based on a modified SMTC.

UE requested SMTC window configuration adaptation

The apparatus determines an association between one or more transmission configuration indicators (TCIs) and one or more corresponding uplink power control (ULPC) configurations based on a control message, receives control information indicating a transmission configuration indicator (TCI) for a transmission on an uplink (UL) channel, and determines a transmission power for the transmission on the uplink (UL) channel based on an uplink power control (ULPC) configuration associated with the transmission configuration indicator (TCI).

Uplink power control (ULPC) indication by associating a ULPC configuration and a transmission configuration indicator (TCI)

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, downlink control information (DCI) scheduling an uplink multiple input multiple output (MIMO) communication. The UE may transmit, and the base station may receive, the uplink MIMO communication using a default sounding reference signal (SRS) resource configuration based at least in part on the UE receiving the DCI prior to a medium access control (MAC) control element (MAC-CE) selecting a subset of uplink transmission configuration indication (TCI) states included in an uplink TCI state pool configured for the UE. Numerous other aspects are provided.
