In some wireless communications systems, a user equipment (UE) may receive, from a base station, downlink control information (DCI) that activates periodic channel state information (CSI) reporting via uplink shared channel transmissions (e.g., via physical uplink shared channel (PUSCH) transmissions). The UE may then identify a trigger condition that triggers a transmission of both a first instance of a CSI report and a second instance of the CSI report within a period of the periodic CSI reporting. Based on the satisfaction of the trigger condition, the UE may transmit the first instance of the CSI report via a first uplink shared channel transmission and the second instance of the CSI report via a second uplink shared channel transmission, where both uplink channel transmissions are within the period of the periodic CSI reporting.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from an access network entity, control signaling indicating first and second search space sets. In some cases, a first set of control channel decoding candidates associated with scheduling a first component carrier may be linked for control channel repetition across the first search space set and the second search space set, and a second set of control channel decoding candidates associated with scheduling a second component carrier may not be linked for control channel repetition. The UE may identify a search space sharing condition for the first and second sets of control channel decoding candidates and monitor the first set of control channel decoding candidates, the second set of control channel decoding candidates, or both, in accordance with the search space sharing condition.

Techniques for search space sharing for control channel repetition

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.

Resolving ambiguities resulting from overlapping physical downlink control channel candidates of different aggregation levels

Methods, systems, and devices for wireless communication are described to support indication of a single frequency network (SFN) mode and associated parameters to a user equipment (UE), while the UE is operating in an idle mode. While operating in the idle mode, the UE may receive signaling from a transmission reception points (TRP), indicating that an SFN will be used for broadcast signaling received concurrently from multiple TRPs. Based on receiving the indication of the SFN, the UE may receive the broadcast signaling via a downlink control channel. For example, the UE may receive the broadcast signaling concurrently from a first TRP via a first beam and from a second TRP via a second beam, where the first and second beams may each be associated with a respective synchronization signal block (SSB).
