Abstract: Various aspects relate to indicating bundling across carriers (e.g., across cells). In some aspects, bundling may involve sending information sent over multiple carriers (e.g., information sent from or to multiple cells) where the information sent over the carriers is combinable at a receiver. For example, a communication device may send the same set of information (e.g., transport blocks with the same content) via multiple carriers, send different redundancy versions of a set of information via different carriers, send information via different beams on different carriers, or send information using a combination of these techniques. The disclosure relates in some aspects to indicating whether bundling is applied across carriers. For example, downlink control information (DCI) that schedules transmissions on multiple carriers (e.g., multiple component carriers) may include an indication of whether bundling is applied across all or a subset of the scheduled carriers.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a maximum permissible exposure (MPE) event associated with a beam, determine that a physical uplink control channel (PUCCH) resource for transmitting a scheduling request is unavailable based at least in part on the identification of the MPE event associated with the beam, and initiate, based at least in part on the determination that the PUCCH resource is unavailable, a physical random access channel (PRACH) procedure to transmit an uplink message. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to inter-band carrier aggregation. A user equipment (UE), for example, may obtain a measured configured maximum UE output power (PUMAX) and prioritize aspects of UE transmissions that contribute to PUMAX. Prioritization may be based, for example, on band priority, channel priority, service priority, or any combination thereof. The power levels related to the prioritized features may be changed by changing a power management maximum power reduction (P-MPR) of each feature associated with the transmission according to the prioritized order of the features. The UE may determine if an electromagnetic power density exposure level of the UE is at or below a predetermined maximum permissible exposure (MPE) level. The UE may continue to reduce the transmitter output power if the electromagnetic power density exposure level is greater than the predetermined MPE level. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to transmit, to a base station, capability signaling indicating a quantity of sounding reference signal (SRS) ports supported by an antenna panel of a set of antenna panels at the UE. The UE may receive control signaling indicating an SRS configuration including multiple SRS sets, multiple SRS resource lists, or both, where the multiple SRS sets or multiple SRS resource lists are associated with respective quantities of supported SRS ports. The UE may then transmit, to the base station and based on the control signaling, a measurement report indicating a quantity of sounding SRS, and transmit an SRS to the base station in accordance with the SRS configuration and the indicated quantity of SRS ports.

Abstract: This disclosure provides systems, methods and apparatus for applying a unified transmission configuration indicator (TCI) state to a downlink reference signal in accordance with a rule or procedure that is mutually known between a user equipment (UE) and one or more components of a base station (BS). In one aspect, the UE and one or more components of the BS may support a unified TCI state associated with a transmission over a downlink data channel and a transmission over a downlink control channel. The UE and one or more components of the BS may apply the unified TCI state to the downlink reference signal (which may be associated with beam selection for the downlink reference signal) in accordance with a satisfaction of a condition associated with the downlink reference signal. Such a condition may be associated with one or more parameters or configurations associated with the downlink reference signal.

Abstract: The present disclosure provides systems, apparatus, methods, and computer-readable media for reducing latency associated with performing some operations that use a reference signal. To illustrate, a user equipment (UE) may receive a reference signal and then may receive a message indicating one or more of an update of a transmission configuration indicator (TCI) state of the UE or a change in designation of a path loss reference signal (PL-RS) measured by the UE. If the reference signal is received within a threshold time period of receiving the message (or vice versa), the UE may perform the update or the change in designation of the PL-RS using one or more parameters determined using the reference signal.

Abstract: A method of wireless communication includes transmitting, by a user equipment (UE) to a base station, a message indicating support of multiple phase tracking reference signal (PTRS) configurations. The method further includes, after transmitting the message, performing a multi-PTRS communication by the UE with the base station. The multi-PTRS communication is performed based on one or more PTRS configurations of the multiple PTRS configurations.

Abstract: Providing downlink and uplink processing is disclosed for a cooperative user equipment (UE) operations. A UE participating in the cooperative UE may determine a processing capability associated with each cooperative operational mode of one or more cooperative operation modes of which the UE is capable. The UE sends a cooperative capability report to a serving base station that includes identification of the one or more capable cooperative operation modes and the processing capability of the UE associated with the each cooperative operation mode. The base station may then configure the UEs based on this capability information. The UEs would receive a cooperative mode configuration message from the serving base station with the configuration of a cooperative operation mode for the UE. The UE may then conduct cooperative UE communications using the configured mode according to its associated processing capability. Other aspects and features are also claimed and described.
