Abstract

A base station transmits a message indicating a small data transmission (SDT) time window for an SDT in a radio resource control (RRC) inactive state. The base station receives, during the SDT time window, an initial uplink transmission that is based on a first power control adjustment (PCA) state being reset to zero. The base station receives a second uplink transmission that is based on a second PCA state, wherein, in response to the second uplink transmission being subsequent to the initial uplink transmission during the SDT time window, the second PCA state is based on the first PCA state and one or more transmit power control command values transmitted during the SDT time window.

Claims (43)

1. A base station comprising:

one or more processors; and

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

transmit a message indicating a small data transmission (SDT) time window for an SDT in a radio resource control (RRC) inactive state;

receive, during the SDT time window, an initial uplink transmission that is based on a first power control adjustment (PCA) state being reset to zero; and

receive a second uplink transmission that is based on a second PCA state, wherein, in response to the second uplink transmission being subsequent to the initial uplink transmission during the SDT time window, the second PCA state is based on:

the first PCA state; and

one or more transmit power control command values transmitted during the SDT time window.

2. The base station of claim 1 , wherein the message further indicates one or more configured uplink grants for the SDT in the RRC inactive state.

3. The base station of claim 1 , wherein receiving the initial uplink transmission is via a first configured uplink grant of one or more configured uplink grants.

4. The base station of claim 1 , wherein receiving the second uplink transmission is via a second configured uplink grant of one or more configured uplink grants.

5. The base station of claim 1 , wherein:

the initial uplink transmission is a new transmission of a first transport block; and

the second uplink transmission is a new transmission of a second transport block.

6. The base station of claim 1 , wherein the instructions further cause the base station to transmit, via a downlink control channel and during the SDT, one or more uplink grants comprising the one or more transmit power control command values.

7. The base station of claim 6 , wherein the one or more uplink grants comprise one or more dynamic grants.

8. A method comprising:

transmitting, by a base station to a wireless device, a message indicating a small data transmission (SDT) time window for an SDT in a radio resource control (RRC) inactive state;

receiving, during the SDT time window, an initial uplink transmission that is based on a first power control adjustment (PCA) state being reset to zero; and

receiving a second uplink transmission that is based on a second PCA state, wherein, in response to the second uplink transmission being subsequent to the initial uplink transmission during the SDT time window, the second PCA state is based on:

the first PCA state; and

one or more transmit power control command values transmitted during the SDT time window.

9. The method of claim 8 , wherein the message further indicates one or more configured uplink grants for the SDT in the RRC inactive state.

10. The method of claim 8 , wherein the receiving the initial uplink transmission is via a first configured uplink grant of one or more configured uplink grants.

11. The method of claim 8 , wherein the receiving the second uplink transmission is via a second configured uplink grant of one or more configured uplink grants.

12. The method of claim 8 , wherein:

the initial uplink transmission is a new transmission of a first transport block; and

the second uplink transmission is a new transmission of a second transport block.

13. The method of claim 8 , further comprising transmitting, via a downlink control channel and during the SDT, one or more uplink grants comprising the one or more transmit power control command values.

14. The method of claim 13 , wherein the one or more uplink grants comprise one or more dynamic grants.

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

transmit a message indicating a small data transmission (SDT) time window for an SDT in a radio resource control (RRC) inactive state;

receive, during the SDT time window, an initial uplink transmission that is based on a first power control adjustment (PCA) state being reset to zero; and

receive a second uplink transmission that is based on a second PCA state, wherein, in response to the second uplink transmission being subsequent to the initial uplink transmission during the SDT time window, the second PCA state is based on:

the first PCA state; and

one or more transmit power control command values transmitted during the SDT time window.

16. The non-transitory computer-readable medium of claim 15 , wherein the message further indicates one or more configured uplink grants for the SDT in the RRC inactive state.

17. The non-transitory computer-readable medium of claim 15 , wherein receiving the initial uplink transmission is via a first configured uplink grant of one or more configured uplink grants.

18. The non-transitory computer-readable medium of claim 15 , wherein receiving the second uplink transmission is via a second configured uplink grant of one or more configured uplink grants.

19. The non-transitory computer-readable medium of claim 15 , wherein:

the initial uplink transmission is a new transmission of a first transport block; and

the second uplink transmission is a new transmission of a second transport block.

20. The non-transitory computer-readable medium of claim 15 , wherein the instructions further cause the base station to transmit, via a downlink control channel and during the SDT, one or more uplink grants comprising the one or more transmit power control command values.
