Abstract
An IAB node performs a method for determining a periodicity of a SSB and/or a RMSI for use in an IAB backhaul link. The method may comprise one or more of: using a predetermined periodicity value; determining a periodicity value based on at least one different parameter; receiving a signaling message indicating a periodicity value and using the indicated periodicity value for the IAB backhaul link; and selecting a periodicity value from a plurality of permitted periodicity values.
Claims18
A method performed at an integrated access and backhaul (IAB) node, comprising:
- when performing initial cell search, assuming a predetermined synchronization signal block (SSB) transmission periodicity;
- searching for an SSB of a cell at the predetermined SSB transmission periodicity;
- acquiring system information from the searched SSB;
- and
- setting up a connection to a first parent IAB node in the searched cell according to the acquired system information.
An integrated access and backhaul (IAB) node, comprising:
- processing circuitry configured to execute program code stored in the memory, cause the IAB node to:
- when performs initial cell search, assume a predetermined synchronization signal block (SSB) transmission periodicity;
- search for an SSB of a cell at the predetermined SSB transmission periodicity;
- acquire system information from the searched SSB;
- and
- set up a connection to a first parent IAB node in the searched cell according to the acquired system information.
