Abstract

Systems, apparatuses, and methods are described for wireless communications. A base station may transmit parameters for a configured grant and a dynamic grant. The parameters may indicate numbers of transmissions of transport blocks within a bundle of a configured grant and within a bundle of a dynamic grant. A wireless device may transmit a first transport block, within a bundle of a configured grant, a first number of times. The wireless device may transmit a second transport block, within a bundle of a dynamic grant, a second number of times.

Claims (57)

1. A method comprising:

receiving, by a wireless device and from a base station, one or more radio resource control messages indicating:

a first number of transmissions for a transport block within a bundle of a configured grant;

a first redundancy version (RV) pattern for the first number of transmissions; and

a second number of transmissions for a transport block within a bundle of a dynamic grant;

transmitting, via at least one radio resource of the configured grant, a first transport block;

causing, based on the first number of transmissions and based on the first RV pattern, one or more first retransmissions of the first transport block;

receiving, by the wireless device, an indication of one or more second radio resources;

transmitting, by the wireless device and via at least one of the one or more second radio resources, a second transport block; and

causing, based on the second number of transmissions and based on a second RV pattern, one or more second retransmissions of the second transport block.

2. The method of claim 1 , further comprising activating, after receiving the one or more radio resource control messages, the configured grant, wherein the configured grant is for one or more uplink transmissions of a configured grant Type 1.

3. The method of claim 1 , further comprising activating, after receiving a control message transmitted via a physical downlink control channel, the configured grant, wherein the configured grant is for one or more uplink transmissions of a configured grant Type 2.

4. The method of claim 1 , further comprising terminating the one or more first retransmissions of the first transport block based on one or more of:

receiving an uplink grant for scheduling the first transport block; or

a quantity of total transmissions of the first transport block being equal to the first number.

5. The method of claim 1 , further comprising terminating the one or more second retransmissions of the second transport block, based on a quantity of total transmissions of the second transport block being equal to the second number.

6. The method of claim 1 , wherein the bundle comprises a transmission time interval (TTI) bundle.

7. The method of claim 1 , wherein the one or more radio resource control messages further indicate:

a first parameter enabling transmission time interval (TTI) bundling for the configured grant; and

a second parameter enabling TTI bundling for the dynamic grant.

8. A method comprising:

receiving, by a wireless device and from a base station, one or more radio resource control messages indicating:

a first number of transmissions for a transport block within a bundle of a configured grant;

a first redundancy version (RV) pattern for the first number of transmissions; and

a second number of transmissions for a transport block within a bundle of a dynamic grant;

transmitting an initial transmission of a first transport block;

retransmitting, a quantity of times equal to one less than the first number and based on the first RV pattern, the first transport block within the bundle of the configured grant;

receiving, by the wireless device, an indication of one or more second radio resources;

transmitting, by the wireless device and via the one or more second radio resources, an initial transmission of a second transport block; and

retransmitting, a quantity of times equal to one less than the second number and based on a second RV pattern, the second transport block within a bundle of the dynamic grant.

9. The method of claim 8 , wherein the retransmitting the first transport block within the bundle of the configured grant is triggered without waiting for feedback from the transmitting the first transport block.

10. The method of claim 8 , wherein the retransmitting the second transport block within the bundle of the dynamic grant is triggered without waiting for feedback from the transmitting the second transport block.

11. The method of claim 8 , further comprising:

receiving an activation command for the configured grant, wherein the activation command is configured via radio resource control messaging or via a physical downlink control channel.

12. The method of claim 9 , wherein the receiving the indication of the one or more second radio resources further comprises:

receiving a second indication of the second RV pattern.

13. A method comprising:

receiving, by a wireless device and from a base station, one or more radio resource control messages comprising:

a first parameter indicating a first number of transmissions for a transport block within a bundle of a configured grant; and

a second parameter indicating a second number of transmissions for a transport block within a bundle of a dynamic grant;

determining, by the wireless device, a type of a grant for an uplink transmission, wherein the type of the grant is either a configured grant or a dynamic grant; and

transmitting, by the wireless device and based on a redundancy version pattern associated with the determined type of grant, a quantity of transmissions of one or more transport blocks within a bundle, wherein:

the quantity of transmissions of the one or more transport blocks within the bundle is based on the type of the grant for the uplink transmission; and

the quantity of transmissions of the one or more transport blocks within the bundle is equal to the first number of transmissions or the second number of transmissions.

14. The method of claim 13 , wherein the configured grant is for one or more uplink transmissions of a configured grant Type 1.

15. The method of claim 14 , further comprising activating, after receiving the one or more radio resource control messages, the configured grant Type 1.

16. The method of claim 13 , wherein the configured grant is for one or more uplink transmissions of a configured grant Type 2.

17. The method of claim 16 , further comprising activating, after receiving a control message transmitted via a physical downlink control channel, the configured grant Type 2.

18. The method of claim 13 , wherein the one or more radio resource control messages further comprise a parameter indicating a sequence of redundant versions of the one or more transport blocks within the bundle.

19. The method of claim 13 , wherein:

the type of the grant is a configured grant;

the quantity of transmissions of the one or more transport blocks within the bundle is equal to the first number of transmissions; and

the first number of transmissions is different from the second number of transmissions.

20. The method of claim 13 , wherein:

the type of the grant is a dynamic grant;

the quantity of transmissions of the one or more transport blocks within the bundle is equal to the second number of transmissions; and

the second number of transmissions is different from the first number of transmissions.
