On-demand synchronization signal block or system information block procedure

A network node for wireless communication, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, which are configured, individually or in any combination, to:
• receive, from a user equipment (UE), a reference signal (RS) measurement report, the RS measurement report being associated with an RS transmitted by a neighbor cell of the UE;
• determine, based at least in part on the RS measurement report, that the neighbor cell is to serve as a secondary cell for the UE or that the neighbor cell is to serve as a primary cell for the UE;
• and
• transmit, to the UE, an indication indicating that the neighbor cell is to serve as the secondary cell for the UE or that the neighbor cell is to serve as the primary cell for the UE.

A network node for wireless communication, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, which are configured, individually or in any combination, to:
• transmit a reference signal (RS) associated with a neighbor cell of a user equipment (UE);
• receive, after transmitting the RS, an indication to transmit at least one of a synchronization signal block (SSB) associated with the neighbor cell or a system information block (SIB) associated with the neighbor cell;
• and
• transmit the at least one of the SSB or the SIB based at least in part on the indication.

A method of wireless communication performed by a user equipment (UE), comprising:

• receiving a reference signal (RS) transmitted by a neighbor cell of the UE;
• transmitting an RS measurement report based at least in part on a measurement of the RS received from the neighbor cell;
• receiving an indication associated with the neighbor cell after transmitting the RS measurement report,
• wherein the indication indicates that the neighbor cell is to serve as a secondary cell for the UE or that the neighbor cell is to serve as a primary cell for the UE;
• and
• receiving, after receiving the indication, at least one of a synchronization signal block (SSB) associated with the neighbor cell or a system information block (SIB) associated with the neighbor cell.
