US Patent 10986695 Uplink cancellation indication signaling

A wireless device receives uplink cancellation indication configuration parameters comprising: a cancellation indication RNTI; and a sequence of serving cell-specific parameters comprising: an identifier of a serving cell; a first parameter indicating a first position in a DCI for the serving cell; and a second parameter indicating a second position in a DCI for a SUL carrier of the serving cell. A first DCI, associated with the cancellation indication RNTI, comprising cancellation indications is received. A determination is made of a first cancellation indication, in the cancellation indications, based on: the first position when a scheduled uplink transmission is for a normal uplink carrier of the serving cell; and the second position when the scheduled uplink transmission is for the SUL carrier of the serving cell. The scheduled uplink transmission is canceled based on the first cancellation indication.
