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.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an uplink message on an uplink channel associated with a special cell (Spcell) to trigger maximum permissible exposure (MPE) reporting based at least in part on an MPE event. The UE may transmit an MPE medium access control (MAC) control element (MAC-CE) to report the MPE event, wherein the MPE MAC-CE is transmitted on a physical uplink shared channel associated with the Spcell or a secondary cell. Numerous other aspects are provided.

Maximum permissible exposure reporting configuration in carrier aggregation and dual connectivity

A user equipment may receive a first physical uplink shared channel (PUSCH) configuration and a second PUSCH configuration. The user equipment may transmit a first uplink communication and a second uplink communication using different antenna panels, based at least in part on the first PUSCH configuration and the second PUSCH configuration.

Multiple uplink configurations for multiple antenna panel transmissions

An apparatus receives at least one scheduling grant scheduling transmission on a first data channel and further scheduling a second data channel. The apparatus reduces a transmit power for the transmission on the first data channel with a first beam when a radio frequency (RF) exposure event occurs. The apparatus increases, after the RF exposure event occurs, a transmit power for the transmission on the second data channel with a second beam. The apparatus transmits an RF exposure report associated with at least one of the first data channel or the first beam to the base station.

Power rebalancing in a maximum permissible exposure event

Determining, by a user equipment (UE) of a wireless communication system, that a physical uplink control channel (PUCCH) transmission of the UE carrying uplink control information (UCI) will collide upon transmission with another physical uplink shared channel (PUSCH) transmission of the UE. The UE then multiplexes, in response to the determining, the UCI on the PUSCH transmission based on one or more of the beam of the PUCCH transmission and the beam of the particular PUSCH transmission.

Uplink control information multiplexing

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a configuration to perform multi-panel communications with a base station using a first panel and a second panel of the UE. The base station may transmit indications of a first slot format and a second slot format for the first panel and the second panel for a time period, at least one symbol for the first slot format having a different communication direction than for the second slot format. The base station may indicate the slot formats in a common configuration and a dedicated configuration for the first panel and the second panel. Additionally or alternatively, the base station may indicate the slot formats in a corresponding downlink control information (DCI) message. The UE and the base station may communicate using the first panel and second panel according to the corresponding slot format.

Methods, systems, and devices for wireless communications are described. Feedback information associated with decoding downlink information may be reported in a first stage and a second stage. A size of the second stage may be restricted by an upper limit associated with an available set of uplink resources for transmitting the feedback information. Limiting the size of the second stage may include reducing a size of second information generated for the second stage, yielding third information for the second stage. The third information may be transmitted with first information generated for the first stage. Limiting the size of the second stage may also include generating second information having a reduced size based on determining that the upper limit may be exceeded. The reduced-size second information may be transmitted with the first information.

A user equipment (UE) and a base station (BS) may transmit reference signals (RS) for the other device to estimate a channel and perform measurements. This disclosure provides for a UE to request a reference signal such as a channel state information (CSI) or a sounding reference signal (SRS). The BS transmits a radio resource control (RRC) message that configures the UE with one or more trigger states for CSI, SRS, or a combination thereof and a media access control (MAC) control element (CE) that activates a subset of the configured trigger states. In one aspect, the UE transmits an uplink request that indicates a trigger state for the UE. corresponding to at least one configured RS. The UE and the BS communicate the at least one RS corresponding to the trigger state for example, based on a grant from the BS or a time offset from the uplink request.
