For CSI reporting, a UE may be configured to generate a CSI report based on a BLER target and on received CSI reference signals (CSI-RSs), where the CSI-RSs may be transmitted on one or more groups of quasi co-located antenna ports. For SRS transmissions, a UE may be configured to transmit SRS based on an SRS configuration determined based on a BLER target. For receiving PDCCH transmissions, a UE may be configured to receive and combine DCI received from multiple base stations. ## Claims ### Claim 1 A user equipment (UE) for wireless communication, comprising: one or more processors configured to cause the UE to: monitor for downlink control information (DCI) in: a first physical downlink control channel (PDCCH) candidate, and a second PDCCH candidate different than the first PDCCH candidate, the first PDCCH candidate corresponding to a same PDCCH candidate index as the second PDCCH candidate;
