Detailed Description
Hereinafter, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.
(1) In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.
(2) "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
Positioning assistance information indication data: the indication data is used to indicate the situation of the positioning assistance information that the network side device can provide, and in the following description of the embodiment, the capability of the positioning assistance information that the network side device can provide is used instead to describe the situation of the positioning assistance information that the network side device can provide.
In the positioning technology discussion of R16NR (New Radio, New air interface), a scheme of how to implement the network side device to broadcast the positioning assistance information is being discussed, and at present, the following scheme is generally adopted:
the LMF (Location Management Function) sends the Location assistance information to be broadcasted to the network side device, and the network side device stores the received Location assistance information and broadcasts it through the system message.
BWP (Bandwidth Part) is a new concept introduced by NR; because the 5G system supports various services and terminals with different forms, the terminals do not adopt uniform bandwidth when transmitting data, the terminals with high data transmission rate require large bandwidth, and the terminals with low data transmission rate only need to support narrow bandwidth; under the BA (Bandwidth adaptation) technique, the Bandwidth of the received data and the Bandwidth of the transmitted data of the UE do not need to be as large as the carrier Bandwidth of the network side device, and a transmission method in which the Bandwidth is a part of resource configuration in the carrier Bandwidth of the entire network side device is called BWP (partial Bandwidth transmission).
Each UE (User Equipment, terminal) may configure multiple BWPs in a cell, except for an initial BWP, for NR Rel-15 release, currently, a network-side device such as a base station may generally configure at most 4 uplink BWPs and 4 downlink BWPs for each connected UE in each cell, and generally only one uplink BWP and one downlink BWP are activated, where:
initial bwp (initial bwp): for PCell (primary cell), BWP for initial access of the terminal to the primary cell; the UE broadcasts a message to acquire initial BWP information in an idle state; the downlink initial BWP may provide the UE with contents such as a synchronization channel and a broadcast message, and the uplink initial BWP may be used for the UE to initiate initial connection establishment.
Bwp (active bwp) activation: the connected UE is used for BWP data transmission with network side devices such as base stations; the network side device may not broadcast the SI on the active BWP, and the UE cannot receive the SI in a broadcast manner and cannot perform subsequent SI update if the UE operates on the active BWP.
As described above, the connected UE may not broadcast the SI on the active BWP, and if the UE is handed over from one cell to another cell and the active BWP of the UE cannot broadcast the SI, the UE cannot know the capability of the network-side device to provide the positioning assistance information, and therefore the UE cannot reasonably send the request message for requesting to acquire the positioning assistance information according to the capability of the network-side device to provide the positioning assistance information, which has not been discussed.
Based on the above situation, the present application provides a method and a device for sending positioning assistance information indication data, so as to provide at least a scheme for knowing a capability of a network side device to provide positioning assistance information, in the scheme, the network side device sends the positioning assistance information indication data to a terminal through a dedicated signaling, the positioning assistance information indication data is used for indicating the capability of the network side device to provide positioning assistance information to the terminal, and correspondingly, the terminal receives the positioning assistance information indication data sent by the network side device through the dedicated signaling, and learns the capability of the network side device to provide positioning assistance information according to the positioning assistance information indication data.

The request may include one or more of the following messages:
first type of information: and confirming whether the network side equipment provides the positioning auxiliary information for the terminal.
Correspondingly, if the terminal determines that the network side device can provide the positioning assistance information required by the terminal according to the response of the network side device, the terminal can continue to request the network side device for the required positioning assistance information,
the second information: and the terminal requests the positioning type of the acquired positioning auxiliary information.
If the terminal sends the positioning type expected to be received to the network side, whether the expected positioning type can be provided is confirmed to the network side equipment, and if the indication that the confirmation of the network side equipment can be provided is obtained, the terminal can further request the relevant positioning content of the positioning type to the network side equipment.
The third information: the terminal requests the type of the positioning assistance information of the acquired positioning assistance information.
If the terminal sends the type of the positioning assistance information expected to be received to the network side, whether the expected type of the positioning assistance information can be provided is confirmed to the network side equipment, and if an indication that the confirmation of the network side equipment can be provided is obtained, the terminal can further request the network side equipment for the related positioning content of the type of the positioning assistance information.
Step S302, the network side device determines the positioning auxiliary information indicating data according to the request of the terminal and sends the positioning auxiliary information indicating data to the terminal.
The network side device may determine corresponding positioning assistance information data according to information carried in the request of the terminal, and send the positioning assistance information data to the terminal.
Step S303, the terminal receives the positioning assistance information indication data sent by the network side device, and learns the capability of the network side device for providing the positioning assistance information according to the positioning assistance information indication data.
