Synchronization signal block periodicity for cell reselection

An apparatus, comprising:

• radio front end circuitry;
• and
• processing circuitry coupled to the radio front end circuitry, wherein the processing circuitry is configured to:
• establish, via the radio front end circuitry, a first connection with a first integrated access and backhaul (IAB) node using a first synchronization signal block (SSB) periodicity;
• perform a cell reselection process that includes determining whether a number of candidate IAB nodes include a candidate IAB node with a previously stored candidate SSB periodicity corresponding to the candidate IAB node;
• determine that there is no previously stored candidate SSB periodicity corresponding to the number of candidate IAB nodes for the cell reselection process;
• and
• in response to the determining, establish, via the radio front end circuitry, a second connection with a second IAB node using a second SSB periodicity, wherein the second SSB periodicity is less than the first SSB periodicity.

A method, comprising:

• establishing a first connection with a first integrated access and backhaul (IAB) node using a first synchronization signal block (SSB) periodicity;
• receiving an SSB from a second IAB node;
• performing radio resource measurement (RRM) using the SSB to determine a second SSB periodicity corresponding to the second IAB node;
• performing a cell reselection process to identify the second IAB node as a candidate IAB node;
• and
• establishing a second connection with the second IAB node using the second SSB periodicity.
