Abstract

A wireless device receives one or more messages. The one or more messages may comprise a first RNTI for a first SPS and a second for a second SPS. A downlink control information (DCI) corresponding to one of the first RNTI or the second RNTI may be received. The DCI may be validated, at least based on a cyclic shift value associated with the DCI, if the DCI corresponds to the first RNTI. Otherwise, the DCI may be validated without considering the cyclic shift value. One of the first SPS or the second SPS, corresponding to the DCI, may be activated in response to the validating being successful.
