Power control for multiple services
A wireless device receives configuration parameters indicating a first cell group for communication with a first base station and a second cell group for communication with a second base station. A determination is made that an allowed total transmission power for at least one first uplink signal of the first cell group based on at least one priority of at least one uplink signal. A determination is made that at least one first transmission power for the one or more first uplink signal based on the allowed total transmission power. The at least one first uplink signals with the at least one first transmission power are transmitted.
1. A method comprising:
determining, by a wireless device, transmission powers of a plurality of uplink channels, comprising a scheduling request (SR) with a first priority and a hybrid automatic request (HARQ) feedback with a second priority, based on the following power priorities in descending order:
a physical random access channel (PRACH) of a primary cell;
a first uplink channel, of the plurality of uplink channels, comprising the SR with the first priority;
a second uplink channel, of the plurality of uplink channels, comprising the HARQ feedback with the second priority, wherein the second priority is lower than the first priority; and
a PRACH of a secondary cell; and
transmitting, by the wireless device and via the plurality of uplink channels, uplink signals with the transmission powers.
2. The method of claim 1 , wherein the plurality of uplink channels comprise a physical uplink control channel (PUCCH).
3. The method of claim 1 , wherein the plurality of uplink channels comprise a physical uplink shared channel (PUSCH).
4. The method of claim 1 , wherein the plurality of uplink channels comprise uplink control information (UCI) with the first priority and data with the second priority.
5. The method of claim 4 , further comprising determining priorities of the plurality of uplink channels based on a higher priority between the first priority and the second priority.
6. The method of claim 1 , wherein the primary cell belongs to a first cell group, and wherein the plurality of uplink channels are transmitted for one or more cells of the first cell group.
7. The method of claim 1 , wherein the first uplink channel is associated with a first service in response to the first uplink channel being configured with the first priority.
8. The method of claim 7 , wherein the first service is an ultra-reliable and low latency communication (URLLC) service.
9. The method of claim 1 , wherein the second uplink channel is associated with a second service in response to the second uplink channel being configured with the second priority.
10. The method of claim 9 , wherein the second service is an enhanced mobile broadband (eMBB) service.
11. 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:
determine transmission powers of a plurality of uplink channels, comprising a scheduling request (SR) with a first priority and a hybrid automatic request (HARQ) feedback with a second priority, based on the following power priorities in descending order:
a physical random access channel (PRACH) of a primary cell;
a first uplink channel, of the plurality of uplink channels comprising the SR with the first priority;
a second uplink channel, of the plurality of uplink channels, comprising the HARQ feedback with the second priority, wherein the second priority is lower than the first priority; and
a PRACH of a secondary cell; and
transmit, via the plurality of uplink channels, uplink signals with the transmission powers.
12. The wireless device of claim 11 , wherein the plurality of uplink channels comprise a physical uplink control channel (PUCCH).
13. The wireless device of claim 11 , wherein the plurality of uplink channels comprise a physical uplink shared channel (PUSCH).
14. The wireless device of claim 11 , wherein the plurality of uplink channels comprise uplink control information (UCI) with the first priority and data with the second priority.
15. The wireless device of claim 14 , wherein the instructions further cause the wireless device to determine priorities of the plurality of uplink channels based on a higher priority between the first priority and the second priority.
16. The wireless device of claim 11 , wherein the primary cell belongs to a first cell group, and wherein the plurality of uplink channels are transmitted for one or more cells of the first cell group.
17. The wireless device of claim 11 , wherein the first uplink channel is associated with a first service in response to the first uplink channel being configured with the first priority.
18. The wireless device of claim 17 , wherein the first service is an ultra-reliable and low latency communication (URLLC) service.
19. The wireless device of claim 11 , wherein the second uplink channel is associated with a second service in response to the second uplink channel being configured with the second priority, wherein the second service is an enhanced mobile broadband (eMBB) service.
20. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a wireless device, cause the wireless device to:
determine transmission powers of a plurality of uplink channels, comprising a scheduling request (SR) with a first priority and a hybrid automatic request (HARQ) feedback with a second priority, based on the following power priorities in descending order:
a physical random access channel (PRACH) of a primary cell;
a first uplink channel, of the plurality of uplink channels comprising the SR with the first priority;
a second uplink channel, of the plurality of uplink channels, comprising the HARQ feedback with the second priority, wherein the second priority is lower than the first priority; and
a PRACH of a secondary cell; and
transmit, via the plurality of uplink channels, uplink signals with the transmission powers.
