Generally, the number of connections supported by the conventional communication system is limited and easy to implement, however, as the communication technology advances, the mobile communication system will support not only conventional communication but also, for example, device-to-Device (D2D) communication, machine-to-machine (Machine to Machine, M2M) communication, machine type communication (Machine Type Communication, MTC), inter-vehicle (Vehicle to Vehicle, V2V) communication, and internet of vehicles (Vehicle to Everything, V2X) systems, etc. Embodiments of the present disclosure may also be applied to these communication systems.
The 5G NR introduces various positioning technologies, and can realize the positioning of the UE. Currently, in some positioning technologies, the UE needs to measure positioning reference signals (Positioning Reference Signal, PRS) sent by the access network device, and thus, in some embodiments, the UE needs to request a Measurement Gap (MG) from the access network device for measuring PRS. Illustratively, the procedure for the UE to request MG is shown in fig. 2. The process comprises the following steps:
step 201, when positioning measurement is needed, sending measurement indication to access network equipment.
That is, when the UE needs to perform the positioning measurement requested by the network, if the MG is not configured for the UE currently, or the configured MG cannot meet the measurement requirement of the UE, the UE requests the MG to the access network device through radio resource control (Radio Resource Control, RRC) signaling, and the access network device may configure the MG for the UE through an RRC message.
The NR Rel-16 system defines a downlink positioning reference signal PRS, supports the PRS which is periodically transmitted, can support the repeated transmission of PRS resource in one period, and further configures the repeated transmission times in the period and the time interval between every two transmissions, wherein the time interval is N slots, and N is a natural number. At present, PRS can only be sent once in one slot, and the number of symbols occupied by PRS can be 2, 4, 6 and 12 symbols in succession in a slot. When requesting the MG from the access network equipment, the UE indicates the period and length of the MG which the UE expects, and the access network equipment configures the MG according to the request of the UE.
Step 202, when positioning measurement is completed, sending measurement indication to access network equipment.
That is, when the UE completes the positioning-related measurement, it may be indicated to the network through an RRC message that the UE has completed the positioning-related measurement.
In addition, to reduce positioning delay, the access network device may pre-configure the MG for the UE, and the LMF may provide auxiliary information to the access network device for determining the pre-configured MG. And the access network device may configure the UE with a positioning reference signal processing window PRS process window, the UE may also measure PRS at PRS process window, and the LMF may provide assistance information to the access network device for determination PRS process window.
In addition, in order to reduce the positioning delay, a concept of a predetermined positioning time (scheduled location time) (T) is introduced, T may be included in a positioning information request (location information request) message sent by the LMF to the UE, and the UE may enter a CONNECTED state (CM-CONNECTED) before T to reduce the positioning delay.
If the UE receives T sent by the LMF, the UE needs to measure the downlink positioning reference signal at T. However, since the access network device does not have information of T, there are cases where T is not in the MG configured by the access network device to the UE, or T is not within PRS process window configured by the access network device to the UE, i.e. according to MG or PRS process window, the UE cannot make measurements of the reference signal at T.
In view of the foregoing, embodiments of the present disclosure relate generally to at least one of the following schemes:
1. the UE sends time information T, namely the preset positioning time (scheduled location time), to the access network equipment when the UE requests the MG to the access network equipment, wherein T represents that the UE expects PRS measurement at the T time;
2. when the LMF provides auxiliary information for pre-configuring the MG to the access network equipment, T is sent to the access network equipment, wherein the T represents that the UE expects PRS measurement at the T time;
3. when the LMF provides assistance information to the access network device for determining PRS process window, T is sent to the access network device, which indicates that the UE desires PRS measurements at time T.
