Abstract: Methods and apparatus are disclosed for a UE and its serving base station to coordinate the activation and deactivation of measurement gaps for performing positioning measurements by the UE using target positioning reference signals (PRS) during bandwidth part (BWP) switching. The UE may be configured by the serving base station to have dedicated measurement gaps. The UE determines if a legacy measurement gap used for mobility measurements or a scheduled data transmission collides with the dedicated measurement gaps. If there is a collision, the UE performs the mobility measurement using the legacy measurement gap or transmits the scheduled data. If there is no collision, the UE receives the PRS to perform the positioning measurement during the dedicated measurement gaps. In one embodiment, based on the status of the active BWP and the target PRS, the UE or the base station may activate or deactivate measurement gaps for the positioning measurements.
