Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a capability to support a mode of uplink control information (UCI) transmission corresponding to transmitting the UCI on an uplink control channel and an uplink signal on an uplink shared channel when the resources of the uplink control channel and the resources of the uplink shared channel are at least partially overlapping. In a first UCI transmission mode, the UE may transmit UCI on an uplink control channel with resources that overlap with an uplink shared channel. In another UCI transmission mode, the UE may multiplex the UCI in the uplink shared channel. The base station may transmit a configuration indicating to the UE to use a UCI transmission mode. The UE may transmit UCI on the uplink control channel and uplink signal on the uplink shared channel based on the configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate via a first panel of the UE and a second panel of the UE. The UE may determine at least one of a first power headroom value for the first panel or a second power headroom value for the second panel, the first power headroom value being specific to the first panel and the second power headroom value being specific to the second panel. The UE may transmit, to a base station, a report indicating at least one of the first power headroom value for the first panel or the second power headroom value for the second panel. In some examples, the base station may receive the report and transmit a signal indicating a power adjustment for at least one of the first panel or the second panel in response to receiving the report.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may communicate, using a first antenna panel, a first reference signal (RS) based at least in part on a first RS configuration, and communicate, simultaneously with the first RS and using a second antenna panel that is different than the first antenna panel, a second RS based at least in part on a second RS configuration, wherein the second RS configuration orthogonalizes the second RS relative to the first RS. Numerous other aspects are provided.

Abstract: 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.

Abstract: A base station may perform a beamforming for a UE group including UEs that are disposed spatially close to each other for MU-MIMO. The base station may generate group common DCI including a beam indication and/or a PL-RS indication for the UE group. The ID included in the group common DCI may be group specific for the UE group or UE specific for a specific UE. The beam indication for different channels may be indicated by an RNTI or an RRC.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for an uplink transmission that is to use multiple antenna panels, a first power splitting for a first transmit power associated with a first antenna panel of the multiple antenna panels, and a second power splitting for a second transmit power associated with a second antenna panel of the multiple antenna panels. The UE may transmit the uplink transmission using the multiple antenna panels according to the first power splitting for the first antenna panel and the second power splitting for the second antenna panel. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive downlink control information (DCI) that schedules a first set of repetitions of an uplink communication according to a first set of transmission parameters, and a second set of repetitions of the uplink communication according to a second set of transmission parameters; determine one or more first phase tracking reference signal (PTRS) port and demodulation reference signal (DMRS) port associations for the first set of repetitions, and one or more second PTRS port and DMRS port associations for the second set of epetitions; and transmit PTRSs in the first set of repetitions and the second set of repetitions based at least in part on the one or more first PTRS port and DMRS port associations and the one or more second PTRS port and DMRS port associations. Numerous other aspects are provided.

Abstract: 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.

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.
