Uplink control information transmission using configured grant in unlicensed cells
A base station transmits, to a wireless device, configuration parameters of one or more configured grants of a cell. The base station receives code block groups, of a transport block, multiplexed with first uplink control information corresponding to the code block groups. The base station transmits a downlink control information indicating one or more negative hybrid automatic repeat request feedback of one or more code block groups of the code block groups. The base station receives, via a radio resource of the one or more configured grants, the one or more code block groups of the transport block and second uplink control information, corresponding to the one or more code block groups, having a first size that is: based on a second size of the one or more code block groups of the transport block, and smaller than a third size of the first uplink control information.
1. A method comprising:
transmitting, by a base station to a wireless device, configuration parameters of one or more configured grants of a cell, wherein the configuration parameters indicate a first value;
receiving code block groups, of a transport block, multiplexed with first uplink control information corresponding to the code block groups;
transmitting a downlink control information indicating one or more negative hybrid automatic repeat request feedback of one or more code block groups of the code block groups; and
receiving via a radio resource of the one or more configured grants:
the one or more code block groups of the transport block; and

2. The method of claim 1 , wherein the second size is a number of the one or more code block groups.
3. The method of claim 1 , wherein the receiving via the radio resource of the one or more configured grants is based on a listen before talk procedure indicating that the radio resource of an unlicensed cell is clear.
4. The method of claim 1 , wherein the second uplink control information is multiplexed with the one or more code block groups based on a rate matching multiplexing process.
5. The method of claim 1 , wherein the second uplink control information indicates at least one of:
a hybrid automatic repeat request process identifier of the transport block;
a code block group transmission information indicating a presence of the one or more code block groups;
a redundancy version of the one or more code block groups of the transport block;
a new data indicator value;
a channel occupancy sharing information; or
an identifier of the wireless device.
6. A base station comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the base station to:
transmit, to a wireless device, configuration parameters of one or more configured grants of a cell, wherein the configuration parameters indicate a first value;
receive code block groups, of a transport block, multiplexed with first uplink control information corresponding to the code block groups;
transmit a downlink control information indicating one or more negative hybrid automatic repeat request feedback of one or more code block groups of the code block groups; and
receive via a radio resource of the one or more configured grants:
the one or more code block groups of the transport block; and
second uplink control information, corresponding to the one or more code block groups, having a first size that is:
based on a second size of the one or more code block groups of the transport block; and
smaller than a third size of the first uplink control information;
wherein the second uplink control information having the first size is in response to the second size being smaller than the first value.
7. The base station of claim 6 , wherein the second size is a number of the one or more code block groups.
8. The base station of claim 6 , wherein the receiving via the radio resource of the one or more configured grants is based on a listen before talk procedure indicating that the radio resource of an unlicensed cell is clear.
9. The base station of claim 6 , wherein the second uplink control information is multiplexed with the one or more code block groups based on a rate matching multiplexing process.
10. The base station of claim 6 , wherein the second uplink control information indicates at least one of:
a hybrid automatic repeat request process identifier of the transport block;
a code block group transmission information indicating a presence of the one or more code block groups;
a redundancy version of the one or more code block groups of the transport block;
a new data indicator value;
a channel occupancy sharing information; or
an identifier of the wireless device.
11. A non-transitory tangible computer-readable medium comprising instructions executable by one or more processors of a base station to cause the base station to:
transmit, to a wireless device, configuration parameters of one or more configured grants of a cell, wherein the configuration parameters indicate a first value;
receive code block groups, of a transport block, multiplexed with first uplink control information corresponding to the code block groups;
transmit a downlink control information indicating one or more negative hybrid automatic repeat request feedback of one or more code block groups of the code block groups; and
receive via a radio resource of the one or more configured grants:
the one or more code block groups of the transport block; and
second uplink control information, corresponding to the one or more code block groups, having a first size that is:
based on a second size of the one or more code block groups of the transport block; and
smaller than a third size of the first uplink control information;
wherein the second uplink control information having the first size is in response to the second size being smaller than the first value.
12. The non-transitory tangible computer-readable medium of claim 11 , wherein the second size is a number of the one or more code block groups.
13. The non-transitory tangible computer-readable medium of claim 11 , wherein the receiving via the radio resource of the one or more configured grants is based on a listen before talk procedure indicating that the radio resource of an unlicensed cell is clear.
14. The non-transitory tangible computer-readable medium of claim 11 , wherein the second uplink control information is multiplexed with the one or more code block groups based on a rate matching multiplexing process.
15. The non-transitory tangible computer-readable medium of claim 11 , wherein the second uplink control information indicates at least one of:
a hybrid automatic repeat request process identifier of the transport block;
