Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sounding reference signal (SRS) configuration indicating a first SRS resource set that includes NSRS,0_21 SRS resources and a second SRS resource set that includes NSRS,0_22 SRS resources, the first SRS resource set and the second SRS resource set being configured for uplink transmissions scheduled by a second downlink control information (DCI) format. The UE may transmit an uplink transmission scheduled using the second DCI format, the uplink transmission being transmitted based at least in part on the SRS configuration. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for receiving an uplink cancelation indication (ULCI) with a number of bits that indicate resources on which one or more uplink channels are to be modified; determining, from at least two uplink transmission groups characterized by different spatial parameters, at least one uplink transmission group to which a received ULCI applies in a component charrier; and modifying the one or more uplink channels that belong to the determined uplink transmission group in accordance with the ULCI. For example, modifying the one or more uplink channels includes at least partially canceling the one or more uplink channels if the resources indicated in the ULCI overlap with the resources of the one or more uplink channels. The one or more uplink channels may include at least one of: one or more physical uplink shared channels (PUSCHs) or one or more PUSCH repetitions.

Abstract: Certain aspects of the present disclosure provide techniques for quasi-colocation (QCL) assumptions, such as QCL assumptions for combined single-DCI (downlink control information) and multi-DCI mTRP (multiple transmission reception point) scenarios. A method that may be performed by a user equipment (UE) includes receiving signaling configuring the UE with a first index value associated with a first plurality of control resource sets (CORESETS) and a second index value associated with a second plurality of CORESETS. The UE may receive at least one medium access control (MAC) control element (CE) that activates a set of transmission configuration indicator (TCI) states, indicates one of the first or second index values, and that maps at least one TCI codepoint in downlink control information (DCI) to two TCI states. The UE may determine one or more TCI states to use for receiving one or more transmissions based, at least in part, on the mapping.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, an indication that the UE is capable of transmitting or receiving transport block (TB) repetitions using spatial division multiplexing (SDM). The UE may receive, from the base station and based at least in part on the indication, at least one downlink control information (DCI) message that schedules a TB in a first resource and a repetition of the TB in a second resource, the first resource and the second resource at least partially overlapping in a time domain and a frequency domain. The UE may communicate the TB and the repetition of the TB using different antenna panels according to the at least one DCI message. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a downlink control information (DCI) message associated with scheduling transmissions for the UE on a plurality of component carriers. The UE may determine, for at least a first component carrier of the plurality of component carriers, that a frequency resource allocation field of the DCI message comprises an indication of a value that is invalid for frequency resource allocation on the first component carrier. The UE may determine, based at least in part on the invalid indication and using a subset of fields of the DCI message corresponding to the first component carrier, that one or more component carriers of the plurality of component carriers are dormant.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine respective sets of time domain resources that are to be used for multiple repetitions of an uplink control information transmission in multiple slots; and transmit one or more of the multiple repetitions using the respective sets of time domain resources, or one or more other resources, in the multiple slots based at least in part on determining the respective sets of time domain resources. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a user equipment (UE) may include receiving, from a base station (BS), a joint sounding reference signal (SRS) resource indicator (SRI), wherein the joint SRI includes a first SRI field and a second SRI field and transmitting, to a transmission/reception point (TRP), one or more physical uplink shared channel (PUSCH) communications based on SRS resources and transmission parameters associated with the joint SRI.

Abstract: Aspects relate to transmission of physical uplink control channel (PUCCH) information. A user equipment may receive a first physical downlink control channel (PDCCH) candidate carried by a control resource set that also carries a second PDCCH candidate, where these PDCCH candidates are associated with different aggregation levels. The user equipment may identify a PUCCH resource for transmission of information (e.g., an ACK or a NACK) that is associated with a physical downlink shared channel (PDSCH) transmission scheduled by the first PDCCH candidate. For example, the user equipment may identify the PUCCH resource based on a control channel element (CCE) index that corresponds to a starting CCE of the first PDCCH candidate and the second PDCCH candidate.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE). The UE may receive signaling configuring the UE with first and second sounding reference signal (SRS) resource sets. The UE may receive a first downlink control information (DCI) that schedules a first physical uplink shared channel (PUSCH) and indicates a first sounding reference signal (SRS) resource indicator (SRI) value, and a second DCI that schedules a second PUSCH and indicates a second SRI value. The UE may determine SRS resources indicated by the first and second SRI values based on an association between control resource set (CORESET) pool index values and the first and second SRS resource sets. The UE may transmit the first PUSCH indicated by the first SRI value and the second PUSCH indicated by the second SRI value, in accordance with the determination.
