1. A method comprising:
receiving, by a wireless device, at least one system information block message indicating an initial bandwidth part configured for the wireless device, wherein the at least one system information block message further indicates whether a second bandwidth part, different from the initial bandwidth part, is configured for the wireless device for uplink data transmission during a radio resource control (RRC) inactive state;
receiving, by the wireless device in an RRC connected state and via a cell, an RRC release message comprising:
an indication to transition the wireless device from the RRC connected state to the RRC inactive state;
an indication of a configured uplink grant to transmit, via the cell and in the RRC inactive state, uplink data; and
an identifier of an index of at least one synchronization signal block (SSB), of a plurality of SSBs of the cell, associated with the configured uplink grant;
transitioning, based on the RRC release message, to the RRC inactive state;
receiving an SSB of the at least one SSB indicated by the RRC release message; and
based on the at least one system information block message indicating the second bandwidth part is not configured for the wireless device for uplink data transmission during the RRC inactive state, transmitting, in the RRC inactive state and using the initial bandwidth part instead of the second bandwidth part, uplink data via the configured uplink grant indicated by the RRC release message.
