The UE transmits, to a location server, a capability message that indicates position capabilities of the UE to support different positioning methods and common information related to the position methods, including that the UE is a NB UE. The UE receives a request for location information that includes a request for positioning measurements for a particular positioning method, a NB message size limit that indicates a limit on an amount of location information to return, and a NB response time to provide the positioning measurements. At least one of the response time or message size limit is different than for the NB UE than for non-NB UEs. The UE enters an idle state, performs the measurements, and transmits at expiry of or before the NB response time, a message containing the measurements. ## Claims ### Claim 1 An apparatus of user equipment (UE), the apparatus comprising: processing circuitry arranged to: decode a request for location information Long Term Evolution (LTE) Positioning Protocol (LPP) message from a location server, the request for location information LPP message comprising a request for positioning measurements and a narrowband (NB) response time to provide the positioning measurements;
