A wireless device receives one or more messages comprising: a parameter indicating that uplink duplication is configured for a bearer corresponding to a first logical channel and a second logical channel; first mapping restrictions of the first logical channel to at least one first cell; and second mapping restrictions of the second logical channel to at least one second cell. A control element indicating activation or deactivation of duplication for the bearer is received. If the control element indicates activation of the duplication, the first mapping restrictions are applied to the first logical channel and the second mapping restrictions are applied to the second logical channel. If the control element indicates deactivation of the duplication, the first mapping restrictions are lifted from the first logical channel and the second mapping restrictions are lifted from the second logical channel.
