Abstract

Claims (28)

1. A base station, comprising:

at least one memory; and

at least one processor coupled with the at least one memory and configured to cause the base station to:

transmit downlink control information (DCI) comprising a transmission configuration indication (TCI), wherein the TCI includes an indication of a first reference signal resource; and

receive a first uplink transmission based on a first transmit power associated with a pathloss based on the first reference signal resource.

2. The base station of claim 1 , wherein the first reference signal resource is a pathloss reference signal resource.

3. The base station of claim 1 , wherein the first reference signal resource is associated with a sounding reference signal (SRS) resource, and wherein the DCI schedules the first uplink transmission associated with the SRS resource, and the first uplink transmission is associated with a first uplink transmission beam pattern based on a corresponding beam pattern associated with the SRS resource.

4. The base station of claim 1 , wherein the first uplink transmission is associated with a first uplink transmission beam pattern based on the first reference signal resource.

5. The base station of claim 1 , wherein the TCI is associated with a first open-loop power control parameter set and a first closed-loop power control process, wherein the first open-loop power control parameter set comprises a first base power level (Po) and a first fractional path-loss compensation factor (alpha), and wherein the first uplink transmission is received based on the first transmit power associated with the pathloss, the first open-loop power control parameter set, and the first closed-loop power control process.

6. The base station of claim 5 , wherein the TCI includes an indication of a first open-loop power control parameter set and the first closed-loop power control process.

7. The base station of claim 1 , wherein the first transmit power for the first uplink transmission is based on a first configured maximum output power associated with the first uplink transmission.

8. The base station of claim 7 , wherein the first configured maximum output power is based on a first antenna array property associated with the first uplink transmission.

9. The base station of claim 8 , wherein the first antenna array property comprises a first number of antenna elements, a first antenna array orientation for a first spatial direction, or a combination thereof.

10. The base station of claim 7 , wherein the first configured maximum output power for the first uplink transmission is based at least in part on a maximum power reduction for the first uplink transmission, and wherein the maximum power reduction for the first uplink transmission is based at least in part on a first uplink transmission beam pattern associated with the uplink transmission.

11. The base station of claim 10 , wherein the first uplink transmission beam pattern is based at least in part on at least one antenna array associated with the uplink transmission.

12. The base station of claim 1 , wherein the at least one processor is configured to cause the base station to:

transmit information of a second uplink transmission, wherein the first uplink transmission and the second uplink transmission overlap in a time domain, wherein the second uplink transmission is associated with a second reference signal resource, and wherein the first reference signal resource is different from the second reference signal resource; and

receive a second uplink transmission based on a second transmit power associated with the second reference signal resource.

13. The base station of claim 12 , wherein a first uplink transmission beam pattern is associated with the first reference signal resource and a second uplink transmission beam pattern is associated with the second reference signal resource, and wherein the second uplink transmission beam pattern is different from the first uplink transmission beam pattern.

14. The base station of claim 13 , wherein the first uplink transmission beam pattern is associated with a first antenna array with a first antenna array property, and wherein the second uplink transmission beam pattern is associated with a second antenna array with a second antenna array property.

15. The base station of claim 13 , wherein the first uplink transmission beam pattern and the second uplink transmission beam pattern are associated with a single antenna array.

16. The base station of claim 12 , wherein the at least one processor is configured to cause the base station to receive a power headroom (PH) for the first uplink transmission and the second uplink transmission.

17. The base station of claim 1 , wherein the at least one processor is configured to cause the base station to receive a power headroom report (PHR) in the first uplink transmission, wherein the PHR comprises a first power headroom (PH) for the first uplink transmission and a first configured maximum output power.

18. A method performed by a base station, the method comprising:

transmitting downlink control information (DCI) comprising a transmission configuration indication (TCI), wherein the TCI includes an indication of a first reference signal resource; and

receiving a first uplink transmission based on a first transmit power associated with a pathloss based on the first reference signal resource.
