To achieve positioning, there are also many positioning technologies, such as New Radio (NR) enhanced cell ID (E-CID) positioning technology, etc. The NR E-CID positioning technology has the following basic principle: and determining the position of the terminal equipment according to the service cell ID (namely the cell-ID) of the service cell where the terminal equipment is located and the direction of the direction angle of the service cell.

Referring to fig. 4, fig. 4 is a flow chart of a positioning method according to an embodiment of the present application. The terminal device in fig. 4 may be the terminal device 20 in fig. 1, and the network device in fig. 4 may be the network device 10 in fig. 1. As shown in fig. 4, the method includes, but is not limited to, the steps of:

401. the network device sends mobility measurement configuration information to the terminal device.

Correspondingly, the terminal equipment receives the mobility measurement configuration information sent by the network equipment.

The mobility measurement configuration information includes first indication information, where the first indication information is used to indicate a transmission receiving point for sending a downlink reference signal.

Wherein the mobility measurement configuration information may be located in a MeasConfig cell.

Exemplary, the IE of the MeasConfig cell (see in particular 3gpp ts 38.331) is as follows:

the mobility measurement configuration information may be configuration information of a plurality of downlink reference signal resources. The downlink reference signals may include, for example, one or more of the following: channel state information reference signals (channel state information reference signal, CSI-RS), positioning reference signals (positioning reference signal, PRS).

The configuration information of the CSI-RS resource may include, for example, one or more of the following: physical layer cell identity, measurement bandwidth, RB frequency domain density and RE index, CSI-RS resource index (CSI-RS-index), period, time domain symbol index, associated synchronization signal block index (ssb-index), whether co-located with associated synchronization signal block (isQuasiColocated), scrambling sequence, etc., without limitation. Wherein, whether to co-locate with the associated synchronization signal block refers to whether to have a quasi co-located or quasi co-located relation (QCL) with CSI-RS.

The configuration information of the PRS resources may include, for example, one or more of the following: bandwidth, subcarrier spacing, comb configuration, slot symbol index, PRS period, data puncturing multiplexing configuration, QCL configuration, without limitation.

Optionally, the configuration information of the plurality of downlink reference signal resources may include configuration information of one or more CSI-RS resources configured by the network device for the terminal device, and configuration information of one or more CSI-RS resources configured by the network device of a neighboring cell of the cell where the network device is located for the terminal device; or, the configuration information of the plurality of downlink reference signal resources may include configuration information of one or more PRS resources configured by the network device for the terminal device, and configuration information of one or more PRS resources configured by the network device of a neighboring cell of the cell where the network device is located for the terminal device, which is not limited herein.

The network device in the neighboring cell of the cell in which the network device is located may be one or more network devices, which is not limited herein.

The IE of the mobility measurement configuration information may be, for example:

optionally, the first indication information is a channel state information reference signal identifier or a positioning reference signal identifier.

The configuration information of the plurality of downlink reference signal resources may include a plurality of first indication information, where the plurality of downlink reference signal resources are in one-to-one correspondence with the plurality of first indication information. If the first indication information is a channel state information reference signal identifier, in the present application, the channel state information reference signal identifier may be global or local in a cell. If the first indication information is the positioning reference signal identifier, in the application, the positioning reference signal identifiers in the positioning reference signal identifiers are the same, and the transmission receiving points indicated by the same positioning reference signal identifier in the positioning reference signal identifiers and transmitting the downlink reference signal are the same transmission receiving points. That is, the transmission receiving points indicated by the same positioning reference signal identifier in the same cell or different cells and transmitting the downlink reference signal are the same transmission receiving points.

Specifically, the channel state information reference signal identifiers are global, and it can be understood that the channel state information reference signal identifiers in the multiple channel state information reference signal identifiers are the same, and the transmission receiving points indicated by the same channel state information reference signal identifier in the multiple channel state information reference signal identifiers and transmitting the downlink reference signal are the same transmission receiving points. That is, the transmission receiving points indicated by the same or different cell in the multiple channel state information reference signal identifiers and transmitting the downlink reference signal are the same transmission receiving points.

For example, the resource of the downlink reference signal a corresponds to CSI-RS-ID1, the resource of the downlink reference signal B corresponds to CSI-RS-ID2, the resource of the downlink reference signal C corresponds to CSI-RS-ID1, and the resource of the downlink reference signal D corresponds to CSI-RS-ID1. The resources of the downlink reference signal a and the resources of the downlink reference signal C are downlink reference signal resources under one cell, and the resources of the downlink reference signal D are downlink reference signal resources under another cell. It can be seen that the resources of the downlink reference signal a, the resources of the downlink reference signal C, and the resources of the downlink reference signal D all correspond to the same CSI-RS-ID. And under the condition that the channel state information reference signal identifier is global, the transmission receiving point for transmitting the downlink reference signal A, the transmission receiving point for transmitting the downlink reference signal B and the transmission receiving point for transmitting the downlink reference signal D are the same transmission receiving point.

Specifically, the channel state information reference signal identifier is local in the cell, which can be understood as: and if the channel state information reference signal identifiers of the cells in the plurality of channel state information reference signal identifiers are the same, the transmission receiving points for transmitting the downlink reference signals indicated by the same channel state information reference signal identifiers in the cells in the plurality of channel state information reference signal identifiers are the same transmission receiving points.

For example, the resource of the downlink reference signal a corresponds to CSI-RS-ID1, the resource of the downlink reference signal B corresponds to CSI-RS-ID2, the resource of the downlink reference signal C corresponds to CSI-RS-ID1, and the resource of the downlink reference signal D corresponds to CSI-RS-ID1. The resources of the downlink reference signal a and the resources of the downlink reference signal C are downlink reference signal resources under one cell, and the resources of the downlink reference signal D are downlink reference signal resources under another cell. It can be seen that the resources of the downlink reference signal a, the resources of the downlink reference signal C, and the resources of the downlink reference signal D all correspond to the same CSI-RS-ID. However, since the resource of the downlink reference signal a and the resource of the downlink reference signal C are downlink reference signal resources in one cell and the resource of the downlink reference signal D is downlink reference signal resources in another cell, the transmission receiving point for transmitting the downlink reference signal a and the transmission receiving point for transmitting the downlink reference signal B are the same transmission receiving point, and the transmission receiving point for transmitting the downlink reference signal D is different from the transmission receiving point for transmitting the downlink reference signal a and is also different from the transmission receiving point for transmitting the downlink reference signal B.

Alternatively, the channel state information reference signal identifier may be located in a cell CSI-RS-Resource-Mobility, or in a cell of similar definition or function, or in a cell of an extension field of CSI-RS-Resource-Mobility, without limitation.
