Abstract

Claims (55)

1 . A method comprising:

receiving, by a wireless device and via a first control resource set (CORESET) of a cell, first downlink control information (DCI) scheduling a first transmission;

based on a first transmission configuration indication (TCI) state of the first CORESET being associated with a first physical cell index (PCI) of the cell, sending the first transmission using a first transmission power based on a first pathloss reference signal;

receiving, via a second CORESET of the cell, second DCI scheduling a second transmission; and

based on a second TCI state of the second CORESET being associated with a second PCI different from the first PCI, sending the second transmission using a second transmission power based on a second pathloss reference signal.

2 . The method of claim 1 , wherein:

the sending the first transmission using the first transmission power comprises determining, based on the first pathloss reference signal, the first transmission power; and

the sending the second transmission using second first transmission power comprises determining, based on the second pathloss reference signal, the second transmission power.

3 . The method of claim 1 , wherein:

the first pathloss reference signal is associated with a first power control parameter set indicated by a first index; and

the second pathloss reference signal is associated with a second power control parameter set indicated by a second index.

4 . The method of claim 1 , wherein:

the sending the first transmission using the first transmission power indicated by the first pathloss reference signal is based on the first DCI not comprising a sounding reference signal resource indicator (SRI) field; and

the sending the second transmission using the second transmission power indicated by the second pathloss reference signal is based on the second DCI not comprising an SRI field.

5 . The method of claim 1 , wherein:

the first TCI state of the first CORESET being associated with the first PCI comprises a first reference signal, indicated for the first TCI state, being associated with the first PCI; and

the second TCI state of the second CORESET being associated with the second PCI comprises a second reference signal, indicated for the second TCI state, being associated with the second PCI.

6 . The method of claim 1 , wherein the second PCI is associated with a non-serving cell.

7 . The method of claim 1 , wherein:

the first transmission power is further based on a first default power control parameter; and

the second transmission power is further based on a second default power control parameter.

8 . The method of claim 1 , further comprising:

receiving, one or more messages comprising one or more configuration parameters of the cell, wherein the one or more configuration parameters indicate two CORESET pool indexes for a plurality of CORESETs, wherein each of the plurality of CORESETs is associated with a respective CORESET pool index of the two CORESET pool indexes; and

receiving one or more messages:

indicating a first transmission configuration indication (TCI) state for the first CORESET, among the plurality of CORESETs and with a first CORESET pool index; and

indicating a second TCI state for the second CORESET, among the plurality of CORESETs and with a second CORESET pool index.

9 . The method of claim 1 , wherein:

the first transmission power is further based on a first target received power; and

the second transmission power is further based on a second target received power.

10 . A method comprising:

receiving, by a wireless device and via a control resource set (CORESET) of a cell, downlink control information (DCI) scheduling a transmission;

determining a pathloss reference signal based on whether a transmission configuration indication (TCI) state of the CORESET is associated with a second physical cell index (PCI) different from a first PCI of the cell; and

sending, via the cell, the transmission using a transmission power based on the pathloss reference signal.

11 . The method of claim 10 , wherein the pathloss reference signal is associated with the second PCI.

12 . The method of claim 10 , wherein the second PCI is associated with a non-serving cell.

13 . The method of claim 10 , wherein the pathloss reference signal comprises a default pathloss reference signal.

14 . The method of claim 10 , further comprising determining, based on the pathloss reference signal, the transmission power for sending the transmission.

15 . The method of claim 10 , further comprising: determining, based on a target received power, the transmission power for sending the transmission.

16 . A method comprising:

receiving, by a wireless device and via a control resource set (CORESET) of a cell, downlink control information (DCI) scheduling a transmission; and

sending, via the cell, the transmission using a transmission power based on:

a first pathloss reference signal if a transmission configuration indication (TCI) state of the CORESET is associated with a first physical cell index (PCI) of the cell; and

a second pathloss reference signal if the TCI state of the CORESET is associated with a second PCI different from the first PCI.

17 . The method of claim 16 , wherein:

the first pathloss reference signal is associated with a first power control parameter set indicated by a first index; and

the second pathloss reference signal is associated with a second power control parameter set indicated by a second index.

18 . The method of claim 16 , wherein:

the transmission power is further based on a first default power control parameter based on the TCI state of the CORESET being associated with the first PCI; and

the transmission power is further based on a second default power control parameter based on the TCI state of the CORESET being associated with the second PCI.

19 . The method of claim 16 , further comprising:

determining, based on the first pathloss reference signal, the transmission power for sending the transmission; and

determining, based on the second pathloss reference signal, the transmission power for sending the transmission.

20 . The method of claim 16 , wherein:

the TCI state of the CORESET being associated with the first PCI comprises a reference signal, indicated for the TCI state, being associated with the first PCI; and

the TCI state of the CORESET being associated with the second PCI comprises the reference signal, indicated for the TCI state, being associated with the second PCI.
