Multiplexing and/or prioritization of uplink signals
A wireless device may receive, via a first control resource set (coreset) with a first coreset group index, downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) transmission. The wireless device may determine that a first quasi co-location (QCL) of the PDSCH transmission is different from a second QCL of a second coreset that overlaps in at least one symbol with the PDSCH transmission, and that the first coreset group index is the same as a second coreset group index of the second coreset. Based on the determining, the wireless device may receive the PDSCH transmission with the second QCL of the second coreset.
