Validation of preconfigured resource in inactive state

A wireless device comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
• receive, in a radio resource control (RRC) connected state, an RRC release message comprising:
• an identifier of a first synchronization signal block (SSB) among a plurality of SSBs of a cell;
• one or more resource parameters of an uplink resource, corresponding to the first SSB, for use in transmission during an RRC inactive state;
• and
• a first threshold for validating the transmission via the uplink resource;
• transition, based on the RRC release message, from the RRC connected state to the RRC inactive state;
• determine that the uplink resource is valid for use in the transmission during the RRC inactive state, in response to a beam measurement value of the first SSB being higher than or equal to the first threshold;
• and
• transmit, based on the determining, a transport block via the uplink resource.

A system comprising:

• a base station comprising:
• one or more first processors;
• and
• first memory storing first instructions that, when executed by the one or more first processors, cause the base station to:
• transmit, to a wireless device in a radio resource control (RRC) connected state, an RRC release message comprising:
• an identifier of a first synchronization signal block (SSB) among a plurality of SSBs of a cell;
• one or more resource parameters of an uplink resource, corresponding to the first SSB, for use in transmission during an RRC inactive state;
• and
• a first threshold for validating the transmission via the uplink resource;
• transition, for the wireless device and based on the RRC release message, from the RRC connected state to the RRC inactive state;
• and
• receive, via the uplink resource, a transport block based on determination of the uplink resource being valid for use in the transmission during the RRC inactive state, wherein the uplink resource being valid is in response to a beam measurement value of the first SSB being higher than or equal to the first threshold;
• and
• the wireless device comprises:
• one or more second processors;
• and
• second memory storing second instructions that, when executed by the one or more second processors, cause the wireless device to:
• receive, in the RRC connected state, the RRC release message;
• transition, based on the RRC release message, from the RRC connected state to the RRC inactive state;
• determine that the uplink resource is valid for use in the transmission during the RRC inactive state, in response to the beam measurement value of the first SSB being higher than or equal to the first threshold;
• and
• transmit, based on the determining, the transport block via the uplink resource.
