In some embodiments, for delayed MT-LR, steps 1-1 to 2-3 are not required for the above-described Figure 3 embodiment because the LMF only needs to obtain the UE capabilities once.

In some embodiments, the above process considers worst-case scenarios, such as obtaining auxiliary data and using measurement gaps.

Compared with ordinary terminal equipment, redcap (Reduced Capability) UE supports a smaller maximum bandwidth and fewer antennas. For example, for FR1, the maximum bandwidth supported by redcap UE is 20MHz. In addition, if redcap UE uses half-duplex mode (such as FDD (Frequency Division Duplexing)), the terminal device can only send or receive information at a certain time, but cannot send and receive information at the same time. Therefore, it is necessary to consider determining the priority of the terminal device sending PRS and receiving SRS (Sounding Reference Signal, channel sounding reference signal), or determining the rules when sending/receiving PRS conflicts with other data.

For HD-FDD (half-duplex frequency division duplex) mode, since the UE cannot send and receive information at the same time, if the UE sends an uplink positioning reference signal, it needs to consider the priority between sending the uplink positioning reference signal and receiving downlink data and/or reference signals. level; if the UE receives positioning reference signals, it needs to consider the priority of receiving downlink positioning reference signals and sending uplink data and/or reference signals.

Figure 4 is a flow chart of a priority indication method for positioning reference signals according to an exemplary embodiment. In this embodiment, the priority indication method for positioning reference signals is applied to the terminal equipment in the network architecture shown in Figure 1 Let’s give an example. The method may include the following step 410.

In step 410, the terminal device receives priority information sent by the access network device or the LMF. The priority information is used to indicate the priority of the terminal device in sending and/or receiving positioning reference signals.

In some embodiments, the access network device or LMF configures priority information for the terminal device, so that the terminal device can send and receive positioning reference signals in an orderly manner according to the priority information, avoiding the delay between sending the positioning reference signal and receiving downlink information. Generate conflicts and avoid conflicts between receiving positioning reference signals and sending downlink information.

In the embodiment of the present disclosure, the terminal device receives the priority information sent by the access network device or the LMF, so that the terminal device can send or receive the positioning reference signal according to the priority information, thereby avoiding the need for the terminal device to send or receive the positioning reference signal and send and receive the positioning reference signal. Conflicts occur between other information, improving the stability of the terminal equipment in sending and receiving positioning reference signals.

Optionally, the priority of the terminal device in sending the positioning reference signal includes: the priority relationship between the terminal device in sending the UL-PRS and receiving downlink information.

In some embodiments, when the terminal device is a redcap UE, because the redcap UE is in HD mode, the terminal device cannot send UL-PRS and receive downlink information at the same time. Therefore, it is necessary to determine whether sending UL-PRS is better than receiving downlink information. The priority of the information enables the terminal to send UL-PRS in an orderly manner, thereby avoiding conflicts between sending UL-PRS and receiving downlink information, and improving the stability of the terminal device in sending and receiving information.

In some embodiments, downlink information includes PDCCH, PDSCH, CSI-RS, etc. In some embodiments, the priority relationship between the terminal device sending UL-PRS and receiving downlink information may include the priority of the terminal device sending UL-PRS relative to receiving PDCCH, the priority of sending UL-PRS relative to receiving PDSCH, sending The priority of UL-PRS relative to receiving CSI-RS.

Optionally, the priority relationship between sending UL-PRS and receiving downlink information can exist in the following situations:

Case 1: The priority of sending UL-PRS is higher than the priority of receiving PDCCH and/or PDSCH and/or CSI-RS.

That is, the priority of sending UL-PRS is higher than the priority of receiving PDCCH; or, the priority of sending UL-PRS is higher than the priority of receiving PDSCH; or, the priority of sending UL-PRS is higher than that of receiving PDSCH. The priority of CSI-RS; or, the priority of sending UL-PRS is higher than the priority of receiving PDCCH and PDSCH; or, the priority of sending UL-PRS is higher than the priority of receiving PDCCH and CSI-RS; or , the priority of sending UL-PRS is higher than the priority of receiving PDSCH and CSI-RS; or, the priority of sending UL-PRS is higher than the priority of receiving PDCCH, PDSCH and CSI-RS.

In some embodiments, the priority of sending UL-PRS is higher than the priority of receiving downlink information, thereby ensuring that UL-PRS can be sent out in time as much as possible.

Case 2: The priority of sending UL-PRS is lower than the priority of receiving PDCCH and/or PDSCH and/or CSI-RS.

That is, the priority of sending UL-PRS is lower than the priority of receiving PDCCH; or the priority of sending UL-PRS is lower than the priority of receiving PDSCH; or the priority of sending UL-PRS is lower than the priority of receiving PDCCH.
