1. A method, comprising:
at a base station of a network operating as a serving cell for a user equipment (UE):
determining whether a target cell of the network transmits Synchronization Signal Block (SSB) information; and
transmitting, to the UE, a measurement configuration message indicating the UE is to measure channel state information reference signals (CSI-RS) from the target cell, wherein the measurement configuration message does not include the SSB information for the target cell but comprises an indication of whether the target cell transmits the SSB information, wherein a search window for the CSI-RS measurement used by the UE is based at least on a timing of the serving cell and a range of the search window is equal to a duration of one of i) two SSB symbols or ii) one physical downlink shared channel (PDSCH) symbol based on a cell phase synchronization error plus an estimated propagation delay between the serving cell and the target cell.
