    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to monitor search spaces on a primary cell and an secondary cell in a carrier aggregation configuration. The UE may monitor the search spaces for control information according to a shared search space monitoring configuration. Based on the shared search space monitoring configuration, the UE may identify that the secondary cell is a scheduling cell and the primary cell is a scheduled cell (e.g., cross-carrier scheduling). The UE may monitor control channel candidates of search spaces on the primary cell and on the secondary cell for downlink control information messages scheduling data transmissions with the primary cell. In some examples, the cross-carrier scheduled communications may be configured according to a scheduling configuration, which may include one or more scheduling constraints.

In some aspects, a user equipment may determine a first configuration for a first sounding reference signal (SRS) set and a second configuration for a second SRS set, the first SRS set to be transmitted using a first group of antennas of the UE and the second SRS set to be transmitted using a second group of antennas of the UE; determine a size of a downlink control information (DCI) field to be included in an uplink DCI communication scheduling a physical uplink shared channel (PUSCH) transmission, the DCI field to indicate a selected SRS set; receive the uplink DCI communication scheduling the PUSCH transmission; and identify the selected SRS set based at least in part on the determined size of the DCI field and information carried in the DCI field. Numerous other aspects are provided.

    Abstract: Aspects relate to implementing a non-dropping rule for mini-slot based repetition of downlink channel data or control. In one example, cancelled repetition may be identified, non-cancelled remaining repetitions may be received, and acknowledgment feedback based on reception results may be generated. In another example, a plurality of time domain resource allocation (TDRA) candidate occasions may be identified where each occasion occurs within a different respective one of a plurality of mini-slots, each mini-slot carrying a different respective one of a plurality of downlink channel repetitions. A TDRA table may be maintained. The TDRA table may include TDRA entries such as location information of the plurality of TDRA candidate occasions associated with the plurality of downlink channel repetitions. The TDRA table may be maintained when at least one of the plurality of downlink channel repetitions is not decoded. A wireless communication device may refrain from dropping non-decoded downlink channel repetitions.

    Abstract: Methods, apparatuses, and computer readable storage medium for PUSCH repetitions and SRS resource sets are provided. An example method includes receiving a configuration of a first SRS resource set and a second SRS resource set. The example method further includes receiving, from a network entity, DCI for an UL transmission, the DCI indicating the first SRS resource set and the second SRS resource set. The first/second SRS resource set is respectively associated with a first/second beam. The example method further includes transmitting, to the network entity, a first set of repetitions of a PUSCH based on the first SRS resource set and a second set of repetitions of the PUSCH based on the second SRS resource set in an order based on information received in the configuration of the first SRS resource set and the second SRS resource set or in the DCI scheduling the UL transmission.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information identifying a plurality of physical downlink control channel (PDCCH) candidates that are to be monitored for downlink control information (DCI). The plurality of PDCCH candidates may include a PDCCH candidate having a first aggregation level and a set of linked PDCCH candidates, for repetitions of DCI, having a second aggregation level. The PDCCH candidate may overlap with one PDCCH candidate of the set of linked PDCCH candidates. The UE may communicate according to one or more rules for the PDCCH candidate overlapping with the one PDCCH candidate of the set of linked PDCCH candidates. Numerous other aspects are described.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an uplink power control configuration for a sounding reference signal (SRS) resource set associated with an uplink component carrier, wherein the uplink power control configuration configures separate power control adjustment states between SRS transmissions and physical uplink shared channel (PUSCH) transmissions, and wherein the uplink power control configuration indicates one of a first SRS power control adjustment state or a second SRS power control adjustment state. The UE may transmit, to the base station, an SRS based at least in part on the uplink power control configuration for the SRS resource set. Numerous other aspects are described.

    Abstract: Certain aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for transmitting repetitions of uplink data (e.g., physical uplink shared channel (PUSCH)), in particular, for transmitting PUSCH repetitions in multiple transmission and reception points (multi-TRP) and/or multi-panel configurations. In a general aspect, the present disclosure provides techniques for signaling user equipment (UE) capability regarding codebook based and non-codebook based uplink transmissions in multi-TRP for improving reliability and robustness. For example, a UE may signal to a network entity an indication of a capability to support PUSCH transmission with at least two sets of repetitions. Each set of repetitions is associated with at least one sounding reference signal (SRS) resource set.
