Scheduling activation and release
A wireless device may receive configuration parameters of an uplink configured grant configuration. A DCI is received that comprises: a HARQ process number field comprising first bit(s); and a redundancy version field comprising second bit(s). A determination is made whether a first value of the first bit(s) indicates a configuration index of the uplink configured grant configuration. A determination is made that the DCI is a valid activation DCI or a valid release DCI: based on the second bit(s) and not based on the first bit(s) in response to the first value indicating the configuration index; and based on the second bit(s) and the first bit(s) in response to the first value not indicating the configuration index. A plurality of resources, associated with the uplink configured grant configuration, are activated or deactivated.

the first sequence of one or more bits are all zeros; and
the second sequence of one or more bits are all zeros.
12. A method comprising:
