A wireless device may receive downlink control information (DCI) scheduling physical uplink shared channel (PUSCH) transmissions for a cell. The DCI may comprise a first phase tracking reference signal-demodulation reference signal (PTRS-DMRS) association field, a second PTRS-DMRS association field, and a sounding reference signal (SRS) resource set field. A first value of the SRS resource set field may indicate the PUSCH transmissions are based on the first PTRS-DMRS association field, and a second value of the SRS resource set field may indicate the PUSCH transmissions are based on both the first PTRS-DMRS association field and the second PTRS-DMRS association field. The wireless device may transmit the PUSCH transmissions based on the SRS resource set field.
