METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING POSITIONING REFERENCE SIGNAL
An apparatus and method for processing positioning reference signal are disclosed. A method may include receiving, by a narrow-band (NB) user equipment (UE), positioning reference signal (PRS) configuration information, determining, by the NB UE, narrowband PRS (NB PRS) configuration information for the NB UE, the NB PRS configuration information comprising information of an NB PRS reference cell that generates an NB PRS for the NB UE, determining, by the NB UE, PRS configuration information for a UE, the UE being assigned to use a frequency band unavailable for the NB UE, and the PRS configuration information comprising information of a PRS reference cell that generates a PRS for the UE, generating, based on the NB PRS configuration information and the PRS configuration information, a reference signal time difference (RSTD) measurement, and transmitting, by the NB UE, the RSTD measurement.
1 . A method performed by a first wireless device, the method comprising:
receiving first information associated with positioning reference signaling and second information associated with narrow-band (NB) positioning reference signaling;
determining, based on the first information, positioning reference signal (PRS) information for one or more wireless user devices, wherein the one or more wireless user devices are capable of using a frequency band not configured for the first wireless device, wherein the PRS information comprises information of a PRS reference cell that transmits a PRS for the one or more wireless user devices, and wherein a portion of the PRS for the one or more wireless user devices is transmitted in a frequency band configured for the first wireless device;
determining, based on the second information, NB PRS information for the first wireless device, wherein the NB PRS information comprises information of an NB PRS reference cell that transmits an NB PRS for the first wireless device;
determining, based on the NB PRS for the first wireless device and based on the portion of the PRS for the one or more wireless user devices, a reference signal time difference (RSTD) measurement; and
transmitting a signal indicating the RSTD measurement.
