Abstract

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.

Claims (55)

1. A wireless device comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, cause the wireless device to:

receive downlink control information (DCI) scheduling physical uplink shared channel (PUSCH) transmissions for a cell, wherein the DCI comprises:

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, wherein:

a first value of the SRS resource set field indicates the PUSCH transmissions are based on the first PTRS-DMRS association field; and

a second value of the SRS resource set field indicates the PUSCH transmissions are based on both the first PTRS-DMRS association field and the second PTRS-DMRS association field; and

transmit the PUSCH transmissions based on the SRS resource set field.

2. The wireless device of claim 1 , wherein the instructions further cause the wireless device to determine, based on the first value or the second value, a PTRS-DMRS association field, from the first PTRS-DMRS association field and the second PTRS-DMRS association field, to apply to a PUSCH transmission of the PUSCH transmissions.

3. The wireless device of claim 1 , wherein the instructions further cause the wireless device to select, based on the first value or the second value, one of the first PTRS-DMRS association field or the second PTRS-DMRS association field to apply to a PUSCH transmission of the PUSCH transmissions.

4. The wireless device of claim 1 , wherein the instructions further cause the wireless device to transmit one or more PTRSs over one or more DMRS ports of the PUSCH transmissions.

5. The wireless device of claim 1 , wherein one of the first PTRS-DMRS association field or the second PTRS-DMRS association field indicates an association between a DMRS port of a PUSCH transmission of the PUSCH transmissions and a PTRS port.

6. The wireless device of claim 1 , wherein the instructions further cause the wireless device to transmit:

a first PTRS over a first DMRS port of a first PUSCH transmission of the PUSCH transmissions; and

a second PTRS over a second DMRS port of a second PUSCH transmission of the PUSCH transmissions.

7. The wireless device of claim 1 , wherein:

the first PTRS-DMRS association field indicates an association between a first DMRS port of a first PUSCH transmission of the PUSCH transmissions and a first PTRS port; and

the second PTRS-DMRS association field indicates an association between a second DMRS port of a second PUSCH transmission of the PUSCH transmissions and a second PTRS port.

8. A base station comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, cause the base station to:

transmit, to a wireless device, downlink control information (DCI) scheduling physical uplink shared channel (PUSCH) transmissions for a cell, wherein the DCI comprises:

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, wherein:

a first value of the SRS resource set field indicates the PUSCH transmissions are based on the first PTRS-DMRS association field; and

a second value of the SRS resource set field indicates the PUSCH transmissions are based on the second PTRS-DMRS association field; and

receive the PUSCH transmissions based on the SRS resource set field.

9. The base station of claim 8 , wherein the instructions further cause the base station to determine, based on the first value or the second value, a PTRS-DMRS association field, from the first PTRS-DMRS association field and the second PTRS-DMRS association field, to apply to a PUSCH transmission of the PUSCH transmissions.

10. The base station of claim 8 , wherein the instructions further cause the base station to select, based on the first value or the second value, one of the first PTRS-DMRS association field or the second PTRS-DMRS association field to apply to a PUSCH transmission of the PUSCH transmissions.

11. The base station of claim 8 , wherein the instructions further cause the base station to receive one or more PTRSs over one or more DMRS ports of the PUSCH transmissions.

12. The base station of claim 8 , wherein one of the first PTRS-DMRS association field or the second PTRS-DMRS association field indicates an association between a DMRS port of a PUSCH transmission of the PUSCH transmissions and a PTRS port.

13. The base station of claim 8 , wherein the instructions further cause the base station to receive:

a first PTRS over a first DMRS port of a first PUSCH transmission of the PUSCH transmissions; and

a second PTRS over a second DMRS port of a second PUSCH transmission of the PUSCH transmissions.

14. The base station of claim 8 , wherein:

the first PTRS-DMRS association field indicates an association between a first DMRS port of a first PUSCH transmission of the PUSCH transmissions and a first PTRS port; and

the second PTRS-DMRS association field indicates an association between a second DMRS port of a second PUSCH transmission of the PUSCH transmissions and a second PTRS port.

15. A non-transitory computer-readable medium storing instructions that, when executed by one or more processors of a wireless device, cause the wireless device to:

receive downlink control information (DCI) scheduling physical uplink shared channel (PUSCH) transmissions for a cell, wherein the DCI comprises:

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, wherein:

a first value of the SRS resource set field indicates the PUSCH transmissions are based on the first PTRS-DMRS association field; and
