Abstract
Disclosed are devices for time synchronization offset identification and refinement for network based positioning in an unlicensed spectrum. An example network device may comprise at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured to, with the at least one processor, cause the network device to receive listen-before-talk (LBT) outcomes from a plurality of base stations (BSs), and identify whether one or more of the plurality of BSs have a time synchronization offset based on the LBT outcomes. The LBT may be related to a reference signal (RS) configured on the BSs. The related methods, apparatuses and computer program product are also disclosed.
