Configured grant for unlicensed cells
A wireless device receives configuration parameters of one or more configured grants of a cell. The wireless device determines a first size of an uplink control information based on a second size of one or more code block groups of a transport block. The wireless device transmits, via a radio resource of the one or more configured grants, the one or more code block groups of the transport block the uplink control information with the first size.
1. A method comprising:
receiving, by a wireless device, configuration parameters of one or more configured grants of a cell;
transmitting code block groups, of a transport block, multiplexed with first uplink control information corresponding to the code block groups;
receiving 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;
determining 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; and
transmitting via a radio resource of the one or more configured grants:
the one or more code block groups of the transport block; and
the second uplink control information having the first size.
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 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.
4. The method of claim 1 , wherein the transmitting 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.
5. 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.
6. The method of claim 1 , wherein the determining the second uplink control information having the first size is in response to the second size being smaller than a first value.
7. The method of claim 6 , wherein the configuration parameters indicate the first value.
8. The method of claim 1 , further comprising:
encoding the transport block into the code block groups.
9. 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 a cell;
transmit code block groups, of a transport block, multiplexed with first uplink control information corresponding to the code block groups;
receive 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;
determine 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; and
transmit via a radio resource of the one or more configured grants:
the one or more code block groups of the transport block; and
the second uplink control information having the first size.
10. The wireless device of claim 9 , wherein the second size is a number of the one or more code block groups.
11. The wireless device of claim 9 , 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 first code block groups of the transport block;
a new data indicator value;
a channel occupancy sharing information; or
an identifier of the wireless device.
12. The wireless device of claim 9 , wherein the transmitting 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.
13. The wireless device of claim 9 , wherein the second uplink control information is multiplexed with the one or more code block groups based on a rate matching multiplexing process.
14. The wireless device of claim 9 , wherein the determining the second uplink control information having the first size is in response to the second size being smaller than a first value indicated by the configuration parameters.
15. The wireless device of claim 9 , wherein the instructions further cause the wireless device to:
encode the transport block into the code block groups.
16. A system comprising:
a base station comprising one or more first processors and first memory storing instructions that, when executed by the one or more first processors, cause the base station to:
transmit configuration parameters of one or more configured grants of a cell; and
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 (HARQ) feedback of one or more code block groups of the code block groups;
receive via a first 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; and
a wireless device comprising one or more second processors and second memory storing second instructions that, when executed by the one or more second processors, cause the wireless device to:
receive the configuration parameters;
transmit the code block groups multiplexed with the first uplink control information corresponding to the code block groups;
receive the downlink control information indicating the one or more negative HARQ feedback of one or more code block groups;
determine the second uplink control information having the first size that is:
based on the second size; and
smaller than the third size; and
transmit, via the radio resource:
the one or more code block groups; and
