Claims (11)

  1. A method comprising: receiving, by a wireless device, a radio resource control, RRC, message comprising: a configured grant, CG, configuration indicating a plurality of CGs; and an unused CG occasion uplink control information, UCI, configuration that comprises a parameter used to determine a size of a bitmap of an unused CG occasion UCI; based on the CG configuration and the unused CG occasion UCI configuration that comprises the parameter, determining that a first CG, of the plurality of CGs, is to be unused for a physical uplink shared channel, PUSCH, transmission; and transmitting the unused CG occasion UCI using a second CG of the plurality of CGs, wherein: the unused CG occasion UCI comprises the bitmap with the size; and the bitmap indicates that the first CG is to be unused for the PUSCH transmission.
  2. The method of claim 1, further comprising not delivering the first CG to a hybrid automatic repeat request, HARQ, entity of the wireless device in response to determining that the first CG is to be unused for the PUSCH transmission.
  3. The method of any of claims 1 to 2, further comprising not delivering a HARQ information, associated with the first CG, to a HARQ entity of the wireless device in response to determining that the first CG is to be unused for the PUSCH transmission.
  4. The method of any of claims 1 to 3, wherein the unused CG occasion UCI is enabled based on the CG configuration comprising the unused CG occasion UCI configuration.
  5. The method of any of claims 1 to 4, further comprising transmitting a user equipment, UE, capability information message indicating that the wireless device supports the unused CG occasion UCI.
  6. The method of any of claims 1 to 5, wherein the plurality of CGs are activated or initialized before the first CG, of the plurality of CGs, is determined to be unused.
  7. A method comprising: transmitting, by a base station to a wireless device, a radio resource control, RRC, message comprising: a configured grant, CG, configuration indicating a plurality of CGs; and an unused CG occasion uplink control information, UCI, configuration that comprises a parameter used to determine a size of a bitmap of an unused CG occasion UCI; and based on the CG configuration and the unused CG occasion UCI configuration that comprises the parameter, receiving, from the wireless device, the unused CG occasion UCI using a second CG of the plurality of CGs, wherein: the unused CG occasion UCI comprises the bitmap with the size; and the bitmap indicates that a first CG, of the plurality of CGs, is to be unused for a physical uplink shared channel, PUSCH, transmission.
  8. The method of claim 7, wherein the unused CG occasion UCI is enabled based on the CG configuration comprising the unused CG occasion UCI configuration.
  9. The method of any of claims 7 to 8, further comprising receiving, from the wireless device, a user equipment, UE, capability information message indicating that the wireless device supports the unused CG occasion UCI.
  10. An apparatus comprising: one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the apparatus to perform the method of any one of claims 1 to 9.
  11. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of an apparatus, cause the apparatus to perform the method of any of claims 1 to 9.
