1. A method comprising, by baseband processor of a wireless device:
receiving first downlink control information (DCI) scheduling a first data stream of a first uplink data communication,
receiving second DCI scheduling a second data stream of a second uplink data communication, wherein transmission of the first and second uplink data streams include simultaneous transmission using two transmission beams; and
transmitting the first and second data streams according to respective scheduling of the first and second DCI;
wherein respective physical uplink shared channels (PUSCHs) of the first and second data streams are configured with distinct transmission configuration indicators (TCIs) in the respective scheduling of the first and second DCI, wherein the first and second data streams are transmitted on corresponding beams associated with channel state information-reference signal/synchronization signal block (CSI-RS/SSB) indices indicated by the distinct TCIs.
