Abstract

A terminal device ( 10 ) includes a transceiver ( 110 ), a camera ( 140 ), a display ( 130 ), and a processor ( 150 ). The processor ( 150 ) determines a first synchronization signal whose radio quality satisfies a predetermined threshold from a plurality of synchronization signals beamformed and transmitted from the base station ( 20 ), and reports the first synchronization signal to the base station ( 20 ). The processor ( 150 ) superimposes a virtual object corrected by using correction information on a captured image of the camera ( 140 ) and displays the image on the display ( 130 ). The correction information is information for indicating a position of an area covered by the first synchronization signal with respect to a real object. The correction information includes information regarding a direction of the virtual object to be displayed on the display ( 130 ) in the area and a distance from the real object to the area.

First claim

The invention claimed is:

1 . A Next Generation Radio Access Network (NG-RAN) node configured to support New Radio Positioning Protocol A (NRPPa), the NG-RAN node comprising:
a network interface configured to communicate with a Location Management Function (LMF) node; and circuitry configured to
receive, from the LMF, an enhanced cell ID (E-CID) MEASUREMENT INITIATION REQUEST message including
a Report Characteristics Information Element (IE); and
a Measurement Quantities Item IE corresponding to a request for the NG-RAN node to report first information indicating Synchronization Signal (SS)/Physical Broadcast Channel (PBCH) block index (SSB index) for location of a User Equipment (UE); and

send, to the LMF, E-CID MEASUREMENT INITIATION RESPONSE message containing the first information indicating the SSB index, in a case that the received Report Characteristics IE is set to OnDemand, or send, to the LMF, E-CID MEASUREMENT REPORT message containing the first information indicating the SSB index, in a case that the received Report Characteristics IE is set to Periodic.

2 . The NG-RAN node of claim 1 , wherein
the first information indicating the SSB index is a beam identifier which indicates a beam for the UE that has a radio quality above a predetermined threshold.

3 . The NG-RAN node of claim 1 , wherein
one or more SSBs each indicated by the SSB index is transmitted from NG-RAN node to the UE.

4 . The NG-RAN node of claim 1 , wherein
the E-CID MEASUREMENT INITIATION RESPONSE message contains Cell Portion Identifier (ID), in the case that the received Report Characteristics IE is set to OnDemand, or the E-CID MEASUREMENT REPORT message contain contains the Cell Portion ID, in the case that the received Report Characteristics IE is set to Periodic.

5 . The NG-RAN node of claim 4 , wherein
the Cell Portion ID corresponds the first information indicating the SSB index.

6 . A Location Management Function (LMF) configured to support New Radio Positioning Protocol A (NRPPa), the LMF comprising:
a network interface configured to communicate with a Next Generation Radio Access Network (NG-RAN) node; and circuitry configured to
send, to the NG-RAN node, enhanced cell ID (E-CID) MEASUREMENT INITIATION REQUEST message including
a Report Characteristics Information Element (IE); and
a Measurement Quantities Item IE that indicates to request the NG-RAN to report first information indicating Synchronization Signal (SS)/Physical Broadcast Channel (PBCH) block index (SSB index) for location of a User Equipment (UE); and

receive, from the NG-RAN node, E-CID MEASUREMENT INITIATION RESPONSE message containing the first information indicating the SSB index, in a case that the received Report Characteristics IE is set to OnDemand, or
receive, from the NG-RAN node, E-CID MEASUREMENT REPORT message containing the first information indicating the SSB index, in a case that the received Report Characteristics IE is set to Periodic.

the first information indicating the SSB index is beam identifier which indicates a beam for the UE that has a radio quality above a predetermined threshold.

8 . The LMF of claim 6 , wherein
one or more SSBs each indicated by the SSB index is transmitted from NG-RAN node to the UE.

9 . The LMF of claim 6 , wherein
the E-CID MEASUREMENT INITIATION RESPONSE message contains Cell Portion Identifier (ID), in the case that the received Report Characteristics IE is set to OnDemand, or the E-CID MEASUREMENT REPORT message contain contains the Cell Portion ID, in the case that the received Report Characteristics IE is set to Periodic.

10 . The LMF of claim 9 , wherein
the Cell Portion ID corresponds the first information indicating the SSB index.

11 . A User Equipment (UE) comprising:
a radio transceiver configured to communicate with a Next Generation Radio Access Network (NG-RAN) node supporting New Radio Positioning Protocol A (NRPPa), wherein first information indicating Synchronization Signal (SS)/Physical Broadcast Channel (PBCH) block index (SSB index) for location of the UE is indicated by Measurement Quantities Item Information Element (IE) which is used by a Location Management Function (LMF) to request the NG-RAN to report the SSB index to the LMF, wherein the Measurement Quantities Item IE and Report Characteristics IE are contained in enhanced cell ID (E-CID) MEASUREMENT INITIATION REQUEST message sent from the LMF to the NG-RAN node, and the first information indicating the SSB index is contained in E-CID MEASUREMENT INITIATION RESPONSE message sent from the NG-RAN node to the LMF, in a case that the received Report Characteristics IE is set to OnDemand, or the first information indicating the SSB index is contained in E-CID MEASUREMENT REPORT message sent from the NG-RAN node to the LMF, in a case that the received Report Characteristics IE is set to Periodic.

12 . The UE of claim 11 , wherein
the first information indicating the SSB index is beam identifier which indicates a beam for the UE that has a radio quality above a predetermined threshold.

13 . The UE of claim 11 , wherein
the radio transceiver is further configured to receive one or more SSBs each indicated by the SSB index.

14 . The UE of claim 11 , wherein
the E-CID MEASUREMENT INITIATION RESPONSE message contains Cell Portion Identifier (ID), in the case that the received Report Characteristics IE is set to OnDemand, or the E-CID MEASUREMENT REPORT message contain contains the Cell Portion ID, in the case that the received Report Characteristics IE is set to Periodic.

15 . The UE of claim 14 , wherein
the Cell Portion ID corresponds the first information indicating the SSB index.

16 . A method for a Next Generation Radio Access Network (NG-RAN) node configured to support New Radio Positioning Protocol A (NRPPa), the method comprising:
communicating with a Location Management Function (LMF) node; and receiving, from the LMF, enhanced cell ID (E-CID) MEASUREMENT INITIATION REQUEST message including
a Report Characteristics Information Element (IE); and
a Measurement Quantities Item IE that indicates to request the NG-RAN to report first information indicating Synchronization Signal (SS)/Physical Broadcast Channel (PBCH) block index (SSB index) for location of a User Equipment (UE); and
sending, to the LMF, E-CID MEASUREMENT INITIATION RESPONSE message containing the first information indicating the SSB index, upon determining that the received Report Characteristics IE is set to OnDemand, or sending, to the LMF, E-CID MEASUREMENT REPORT message containing the first information indicating the SSB index, upon determining that the received Report Characteristics IE is set to Periodic.
