Abstract

A wireless device receives power control parameters of a physical uplink shared channel (PUSCH) of a bandwidth part of a cell. The power control parameters indicate first power values and second power values, and each power value of the first power values and the second power values is associated with a respective index. A downlink control information (DCI) indicating a transmission via the PUSCH is received. Based on the DCI, one of the first power values and the second power values is determined as determined power values for transmission of a transport block. The transport block is transmitted, via the PUSCH, with a transmission power based on a power value with a lowest index among indexes associated with the determined power values.

First claim

What is claimed is:

1. A method comprising:
receiving, by a wireless device, power control parameters of a physical uplink shared channel (PUSCH) of a bandwidth part of a cell, wherein:
the power control parameters indicate first power values and second power values; and
each power value of the first power values and the second power values is associated with a respective index;

receiving downlink control information (DCI) indicating a transmission via the PUSCH;
determining, based on the DCI, one of the first power values or the second power values as determined power values for transmission of a transport block; and
transmitting, via the PUSCH, the transport block with a transmission power based on a power value with a lowest index among indexes associated with the determined power values.

2. The method of claim 1 , wherein each power value of the first power values and the second power values is an initial target received power of the PUSCH for a base station.

3. The method of claim 2 , comprising determining the transmission power further based on a pathloss value.

4. The method of claim 1 , wherein a DCI format of the DCI does not comprise a sounding reference signal resource indicator (SRI) field when a length of the SRI field is zero.

5. The method of claim 1 , further comprising receiving configuration parameters of a plurality of control resource sets.

6. The method of claim 5 , wherein the plurality of control resource sets are grouped into a plurality of control resource set groups, and wherein each of the plurality of control resource set groups being identified with a control resource set pool index.

7. The method of claim 6 , wherein a control resource set group is associated with a transmission and reception point (TRP) of a plurality of TRPs of a base station.

8. The method of claim 1 , wherein:
the first power values are associated with a first panel of a plurality of panels for transmission of the transport block via the PUSCH; and
the second power values are associated with a second panel of the plurality of panels for transmission of the transport block via the PUSCH.

9. The method of claim 8 , further comprising selecting the first power values, from the first power values and the second power values, for the transmission of the transport block, via the PUSCH, based on the transmission of the transport block, via the PUSCH, being associated with the first panel of the plurality of panels.

10. The method of claim 8 , further comprising transmitting, via the first panel of the plurality of panels, the transport block with the transmission power determined based on the first power values associated with the first panel.

11. A wireless device comprising:
one or more processors;
memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
receive power control parameters of a physical uplink shared channel (PUSCH) of a bandwidth part of a cell, wherein:
the power control parameters indicate first power values and second power values; and
each power value of the first power values and the second power values is associated with a respective index;

receive downlink control information (DCI) indicating a transmission via the PUSCH;
determine, based on the DCI, one of the first power values or the second power values as determined power values for transmission of a transport block; and
transmit, via the PUSCH, the transport block with a transmission power based on a power value with a lowest index among indexes associated with the determined power values.

12. The wireless device of claim 11 , wherein each power value of the first power values and the second power values is an initial target received power of the PUSCH for a base station.

13. The wireless device of claim 12 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to determine the transmission power further based on a pathloss value.

14. The wireless device of claim 11 , wherein a DCI format of the DCI does not comprise a sounding reference signal resource indicator (SRI) field when a length of the SRI field is zero.

15. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to receive configuration parameters of a plurality of control resource sets.

16. The wireless device of claim 15 , wherein the plurality of control resource sets are grouped into a plurality of control resource set groups, and wherein each of the plurality of control resource set groups being identified with a control resource set pool index.

17. The wireless device of claim 16 , wherein a control resource set group is associated with a transmission and reception point (TRP) of a plurality of TRPs of a base station.

18. The wireless device of claim 11 , wherein:
the first power values are associated with a first panel of a plurality of panels for transmission of the transport block via the PUSCH; and
the second power values are associated with a second panel of the plurality of panels for transmission of the transport block via the PUSCH.

19. The wireless device of claim 18 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to select the first power values, from the first power values and the second power values, for the transmission of the transport block, via the PUSCH, based on the transmission of the transport block, via the PUSCH, being associated with the first panel of the plurality of panels.

20. The wireless device of claim 18 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to transmit, via the first panel of the plurality of panels, the transport block with the transmission power determined based on the first power values associated with the first panel.
