Abstract

A wireless device receives configuration parameters of one or more configured grants of an unlicensed cell. The wireless device transmits, based on a configured grant of the one or more configured grants, one or more code block groups of a transport block and a code block group transmission information. The code block group transmission information indicates a presence of the one or more code block groups for the transport block. The wireless device receives a downlink control information comprising a first field and a second field. The first field indicates that the base station received the code block group transmission information. The second field indicates hybrid automatic repeat request feedbacks for the one or more code block groups.

First claim

What is claimed is:

1. A method comprising:
receiving, by a wireless device, configuration parameters of one or more configured grants of an unlicensed cell;
transmitting to a base station and based on a configured grant of the one or more configured grants:
one or more code block groups of a transport block; and
a code block group transmission information indicating a presence of the one or more code block groups for the transport block; and

receiving a downlink control information comprising:
a first field indicating that the base station received the code block group transmission information; and
a second field indicating hybrid automatic repeat request feedback for each code block group of the one or more code block groups.

2. The method of claim 1 , wherein the transmitting the one or more code block groups is based on a listen before talk procedure indicating a clear channel.

3. The method of claim 1 , further comprising encoding the transport block to generate a first number of code block groups corresponding to the transport block, wherein a number of the transmitted one or more code block groups is equal to the first number of code block groups corresponding to the transport block.

4. The method of claim 1 , further comprising encoding the transport block to generate a first number of code block groups corresponding to the transport block, wherein a number of the transmitted one or more code block groups is less than the first number of code block groups corresponding to the transport block.

5. The method of claim 1 , further comprising transmitting, based on the configured grant, uplink control information comprising hybrid automatic repeat request parameters of the transport block.

6. The method of claim 5 , wherein the hybrid automatic repeat request parameters comprise a hybrid automatic repeat request identifier of the transport block.

7. The method of claim 1 , further comprising transmitting, based on the configured grant, an uplink assignment index that identifies the transmission of the one or more code block groups of the transport block.

8. The method of claim 1 , wherein the configuration parameters indicate a bitmap comprising a plurality of bits, a value of a bit in the plurality of bits indicates whether a corresponding slot is configured with a configured grant.

9. The method of claim 1 , wherein the one or more code block groups of the transport block are transmitted via a physical uplink shared channel.

10. The method of claim 9 , wherein an uplink control information comprising the code block group transmission information is multiplexed with the one or more code block groups of the transport block.

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:
receive configuration parameters of one or more configured grants of an unlicensed cell;
transmit to a base station and based on a configured grant of the one or more configured grants:
one or more code block groups of a transport block; and
a code block group transmission information indicating a presence of the one or more code block groups for the transport block; and

receive a downlink control information comprising:
a first field indicating that the base station received the code block group transmission information; and
a second field indicating hybrid automatic repeat request feedback for each code block group of the one or more code block groups.

12. The wireless device of claim 11 , wherein the transmitting the one or more code block groups is based on a listen before talk procedure indicating a clear channel.

13. The wireless device of claim 11 , wherein the instructions further cause the wireless device to encode the transport block to generate a first number of code block groups corresponding to the transport block, wherein a number of the transmitted one or more code block groups is equal to the first number of code block groups corresponding to the transport block.

14. The wireless device of claim 11 , wherein the instructions further cause the wireless device to encode the transport block to generate a first number of code block groups corresponding to the transport block, wherein a number of the transmitted one or more code block groups is less than the first number of code block groups corresponding to the transport block.

15. The wireless device of claim 11 , wherein the instructions further cause the wireless device to transmit, based on the configured grant, uplink control information comprising hybrid automatic repeat request parameters of the transport block.

16. The wireless device of claim 15 , wherein the hybrid automatic repeat request parameters comprise a hybrid automatic repeat request identifier of the transport block.

17. The wireless device of claim 11 , wherein the instructions further cause the wireless device to transmit, based on the configured grant, an uplink assignment index that identifies the transmission of the one or more code block groups of the transport block.

18. The wireless device of claim 11 , wherein the configuration parameters indicate a bitmap comprising a plurality of bits, a value of a bit in the plurality of bits indicates whether a corresponding slot is configured with a configured grant.

19. The wireless device of claim 11 , wherein the one or more code block groups of the transport block are transmitted via a physical uplink shared channel.

20. A system comprising:
a base station; and
a wireless device, wherein:
the base station comprises one or more processors of the base station and memory storing instructions of the base station that, when executed by the one or more processors of the base station, cause the base station to:
transmit configuration parameters of one or more configured grants of an unlicensed cell;
receive based on a configured grant of the one or more configured grants:
one or more code block groups of a transport block; and
a code block group transmission information indicating a presence of the one or more code block groups for the transport block; and

transmit a downlink control information comprising:
a first field indicating that the base station received the code block group transmission information; and
a second field indicating hybrid automatic repeat request feedback for each code block group of the one or more code block groups; and

the wireless device comprises one or more processors of the wireless device and memory storing instructions of the wireless device that, when executed by the one or more processors of the wireless device, cause the wireless device to:
receive the configuration parameters;
transmit the one or more code block groups of a transport block and the code block group transmission information; and
receive the downlink control information.
