Abstract
A method of reference signal received power (RSRP) reporting for New Radio (NR) high resolution angle-based downlink positioning is proposed. UE measures positioning reference signal (PRS) resource sets by performing beam sweeping for a coarse direction search, and then fixes RX beam for RSRP measurements. UE derives RSRP measurement results for each PRS resource set, which comprises multiple PRS resources. UE reports RSRP measurement results of a portion of PRS resource sets. The reported RSRP measurement results comprise an RSRP ratio or a differential RSRP with respect to a highest RSRP value of a PRS resource in a reported PRS resource set.
Claims14
A method comprising:
- receiving configuration information by a User Equipment (UE) in a communication network, wherein the configuration information comprises multiple positioning reference signal (PRS) resource sets for UE measurements and reporting, wherein each PRS resource set comprises multiple PRS resources of a transmission/reception point (TRP) and each PRS resource has a PRS resource ID and is associated with a beam of the TRP;
- determining reference signal received power (RSRP) measurement results of the configured PRS resource sets by performing measurements on PRSs over the configured PRS resource sets transmitted from multiple TRPs;
- and
- reporting RSRP measurement results of a portion of PRS resource sets, wherein the reported RSRP measurement results comprise an RSRP ratio or a differential RSRP with respect to a highest RSRP value of a PRS resource in a reported PRS resource set.
A User Equipment (UE) comprising:
- a receiver that receives configuration information in a communication network, wherein the configuration information comprises multiple positioning reference signal (PRS) resource sets for UE measurements and reporting, wherein each PRS resource set comprises multiple PRS resources of a transmission/reception point (TRP) and each PRS resource has a PRS resource ID and is associated with a beam of the TRP;
- a measurement module that determines reference signal received power (RSRP) measurement results of the configured PRS resource sets by performing measurements on PRSs over the configured PRS resource sets transmitted from multiple TRPs;
- and
- a transmitter that reports RSRP measurement results of a portion of PRS resource sets, wherein the reported RSRP measurement results comprise an RSRP ratio or a differential RSRP with respect to a highest RSRP value of a PRS resource in a reported PRS resource set.
