Handling positioning reference signals in wireless systems

A method implemented by a wireless transmit/receive unit (WTRU), the method comprising:

• receiving radio resource control (RRC) configuration information from a network device, wherein the RRC configuration information indicates multiple configurations associated with a positioning reference signal (PRS), and wherein each respective configuration of the multiple configurations indicates a time period for measuring the PRS and a priority of the PRS;
• receiving an indication that the time period indicated by one of the multiple configurations is available for measuring the PRS, wherein the indication is received from the network device via a media access control (MAC) control element (CE);
• determining, based at least on the indication received from the network device, whether the PRS has a higher priority than one or more other downlink transmissions associated with the time period for measuring the PRS;
• and
• based on a determination that the PRS has the higher priority than the one or more other downlink transmissions associated with the time period and a further determination that the time period is outside a measurement gap configured for the WTRU, receiving the PRS instead of the one or more other downlink transmissions during the time period.
