Since the first measurement information of the positioning reference signal is transmitted in a broadcast manner, the network device may simultaneously pre-configure the measurement information of the positioning reference signal for a plurality of terminal devices.

Description
Technical Field
The present application relates to the field of positioning technologies, and in particular, to a communication method and a communication device in a positioning process.
Background
In the latest third generation partnership project (3rd generation partnership project,3GPP) standard, a variety of positioning techniques are supported, including downlink positioning techniques. Namely, the terminal equipment measures the positioning reference signal received from the access network equipment, and then positions the terminal equipment according to the measurement result.
To reduce positioning latency, the access network device may pre-configure the positioning measurement configuration using radio resource control (radio resources control, RRC) signaling. However, this requires the access network device to pre-configure the positioning measurement configuration for each terminal device separately, which is a large signaling overhead.
Disclosure of Invention
The application provides a communication method and a communication device, which are used for reducing signaling overhead of measurement configuration for informing a terminal side device of a positioning reference signal supported by the terminal side device.
In a first aspect, a communication method is provided that may be performed by a first communication device, which may be a terminal device, or which is a communication device, such as a chip system, capable of supporting the functions required by the terminal device to implement the method. It should be understood that the chip system may be provided in the terminal device. The following describes an example of the first communication apparatus as a terminal device. The method comprises the following steps:
the terminal device receives a broadcast message sent from the network device, the broadcast message including first information including first measurement information of the positioning reference signal, so that the terminal device performs positioning measurement based on the first information. In this scheme, the first measurement information of the positioning reference signal is sent in a broadcast manner, so that the network device can simultaneously pre-configure the measurement information of the positioning reference signal for a plurality of terminal devices. Compared with the network equipment which pre-configures the measurement information of the positioning reference signals for each terminal equipment, the signaling overhead for configuring the measurement information of the positioning reference signals can be reduced.
Wherein the first measurement information may be considered as measurement information of a positioning reference signal configured by the network device. The first measurement information may include one or more sets of measurement information. The set of measurement information may include one or more measurement parameters. The first measurement information may also be considered as measurement information of a positioning reference signal preconfigured by the network device. For example, the first measurement information includes one or more sets of measurement pre-configuration information. The set of measurement provisioning information may include one or more measurement provisioning parameters. Measurement preconfiguration information may also be understood as preconfigured measurement information. It is understood that "pre-configuration" refers to that the access network device sends measurement information related to the positioning reference signal to the terminal device or the positioning management device in advance. The terminal device or the positioning management device may request activation or deactivation of the preconfigured measurement information from the access network device according to the requirements. Accordingly, the access network device may activate or deactivate the preconfigured measurement information by signaling or message in response to a request from the terminal device or the location management device.
In a possible implementation, the broadcast message is a positioning system information block (positioning system information blocks, posSIB), such as posSibType6-1, or a newly defined posSIB. It is understood that the posSIB is dedicated to broadcasting positioning assistance data. And the measurement information of the positioning reference signal belongs to positioning assistance data, so that the same measurement information can be broadcast for a plurality of cells at the same time by carrying the first measurement information through the posSIB. In addition, the terminal equipment in the non-connection state, for example, the terminal equipment in the RRC idle state or the RRC inactive state, can acquire measurement information of the positioning reference signal by receiving the posSIB, and then perform positioning measurement. Namely, the terminal equipment can perform positioning measurement without entering a connection state, so that the positioning of the terminal equipment in a non-connection state can be realized, and the method is particularly suitable for a moving scene of the terminal equipment.
In another possible implementation, the broadcast message is a system information block (system information blocks, SIB), such as SIB11, or other possible system information block, such as a newly defined SIB. It can be appreciated that SIB11 contains information related to measurement in the non-connected state, and therefore, measurement information of a positioning reference signal applicable to the terminal device in the non-connected state is carried by SIB 11. The terminal equipment in the non-connection state can acquire the measurement information of the positioning reference signal by receiving the SIB11, thereby realizing the positioning of the terminal equipment in the non-connection state. In addition, the access network equipment can sense the content of the measurement information carried by the SIB11, so that corresponding resource scheduling can be effectively carried out.
In a possible implementation, the first information includes first indication information for indicating that at least one set of measurement information in the first measurement information is available for the terminal device in the non-connected state, and/or the first indication information indicates that the terminal device in the non-connected state is allowed to request at least one set of measurement information in the first measurement information. The at least one set of measurement information may also be replaced by the at least one measurement parameter, the at least one set of measurement pre-configuration information, or the at least one measurement pre-configuration parameter. The behavior of the non-connected terminal device may also be different depending on the content of the first indication information. For example, the first indication information indicates that the terminal device in the non-connection state may request part of the measurement information in the first measurement information, and the terminal device in the non-connection state may explicitly request part of the measurement information according to the first indication information, so that the terminal device in the subsequent non-connection state may request the part of the measurement information, so as to avoid sending unnecessary requests. For another example, the first indication information indicates that part of the measurement information in the first measurement information is available for the terminal device in the non-connected state, and the terminal device in the non-connected state can consider that the part of the measurement information can be used without passing the request.
In a possible implementation, the first information includes second indication information indicating that the request for second measurement information is allowed, the second measurement information being different from the first measurement information. The first measurement information may be considered as measurement information of a positioning reference signal preconfigured or configured by the network device. The second measurement information is different from the first measurement information, and it can be considered that the second measurement information is measurement information other than the first measurement information, that is, measurement information other than the first measurement information range. For example, the first measurement information only contains pre-configured or configured measurement gap configuration information, then the second measurement information may be measurement process window configuration information. In the scheme, the first information can indicate whether the terminal equipment can request the second measurement information through the second indication information, so that the terminal equipment can determine whether to request the second measurement information from the network equipment under the condition that the first measurement information does not meet the requirement according to the second indication information. For example, the second indication information indicates that the request of the second measurement information is allowed, and when the first measurement information of the terminal device does not meet the requirement, the request of the second measurement information can be requested, so that the flexibility of the request can be increased, and the positioning measurement performance can be improved.
In a possible implementation manner, the method further includes: the terminal device sends a request message, which may be used to request activation of at least one set of measurement information in the first measurement information, and/or which may be used to request at least one set of measurement information in the second measurement information. Similar to the first measurement information, the second measurement information also includes one or more sets of measurement information configured or preconfigured by the network device. In the scheme, the terminal equipment can request one or more sets of measurement information in the first measurement information, can request one or more sets of measurement information in the second measurement information, or can request part of measurement information of the first measurement information and part of measurement information in the second measurement information at the same time, and specifically request which measurement information can be determined according to actual requirements, so that the scheme is more flexible.
In a possible implementation manner, the method further includes: the terminal device receives a response message sent by the network device, where the response message includes at least one set of measurement information in the first measurement information and/or at least one set of measurement information in the second measurement information, or the response message is used to instruct to activate at least one set of measurement information in the first measurement information. In the scheme, the network equipment responds to the request of the terminal equipment and can inform the terminal equipment of the measurement information of the positioning reference signals which can be used by the terminal equipment, so that the terminal equipment can perform positioning measurement. For example, the response message includes at least one set of measurement information of the first measurement information and/or at least one set of measurement information of the second measurement information. For another example, the response message may indicate that at least one set of measurement information in the first measurement information is activated, which may save signaling overhead.
In a possible implementation manner, the method further includes: the terminal equipment receives second information sent by the network equipment, the second information comprises third measurement information of the positioning reference signal, and the terminal equipment performs positioning measurement according to the first information and the second information. The third measurement information may be measurement information related to positioning, which is sent by the network device to the specific terminal device through a unicast message, for example, measurement information configured by the network device, measurement information activated by the network device (belonging to preconfigured measurement information), or positioning assistance information. For example, the third measurement information may be activated measurement information that is sent by the access network device or the positioning management device to the specific terminal device by means of a unicast message. Since the third measurement information is specific to the specific terminal device, the terminal device may perform positioning measurement based on the second information. When the network device configures the first measurement information and the third measurement information at the same time, the terminal device may perform positioning measurement according to the first information and/or the second information. That is, the terminal device may request more appropriate measurement information from the network according to the requirement, or may use more appropriate measurement information according to the requirement.
In a possible implementation, the first measurement information includes one or more of the following: measurement configuration information of a positioning reference signal, identification (ID) of the measurement configuration information, region information associated with the measurement configuration information, measurement configuration priority information, third indication information, or frequency point information associated with the measurement configuration information. Wherein the measurement configuration information of the positioning reference signal comprises measurement interval configuration information and/or measurement processing window configuration information. The third indication information is used for indicating whether the terminal equipment is allowed to request to activate or deactivate the measurement information of the positioning reference signal. The terminal device can be explicitly informed whether to request to activate or deactivate the measurement configuration information of the positioning reference signal by the third indication information. The terminal device in the non-connected state may consider that it may request to activate or deactivate measurement configuration information of the positioning reference signal according to the third indication information. Under the condition, the terminal equipment in the non-connection state can acquire the measurement information of the positioning reference signal without entering the connection state, so that the positioning of the terminal equipment in the non-connection state can be realized based on less signaling interaction, and the energy consumption of the terminal equipment can be saved. The first measurement information includes the third indication information, so that the network device does not need to additionally transmit signaling for indicating whether to allow the terminal device to request activation or deactivation of measurement configuration information of the positioning reference signal, which can save signaling overhead.
In a possible implementation, the request message includes one or more of the following associated with the measurement information: ID. Region information, priority information, frequency point information, or fourth indication information for indicating that measurement information not belonging to the first measurement information is requested. The terminal device indicates that the first measurement information does not meet the measurement requirement of the terminal device through the fourth indication information, so that the terminal device expects to request measurement information beyond the first measurement information to improve positioning measurement performance.
In a possible implementation, the request message is a message sent by a terminal device in a non-connected state. If the first indication information indicates that at least one set of measurement information in the first measurement information is available for the terminal equipment in the non-connection state, the terminal equipment in the non-connection state can send a request message, so that positioning can be realized for the terminal equipment in the non-connection state.
In a possible implementation manner, the request message is a message 1 in the random access process, and the response message is a message 4 in the random access process; or the request message is a message A in the random access process, and the response message is a message B in the random access process; or the request message is a pre-configuration authorization request message, and the response message is a pre-configuration authorization response message. The measurement information of the positioning reference signal can be requested through the message 1 or the message A or the pre-configured authorization request message in the random access process, and the terminal equipment is not required to complete the random access. By the scheme, communication flows such as random access and the like which are needed to be executed by the terminal equipment before being positioned are reduced, the positioning process can be simplified, and positioning of the terminal equipment in a non-connection state can be realized.
In a second aspect, a communication method is provided that may be performed by a second communication device, which may be a network apparatus, such as an access network apparatus or a location management apparatus, or which is a communication device, such as a chip system, capable of supporting the functions required by the network apparatus to implement the method. It should be understood that the system-on-chip may be provided in a network device. The second communication apparatus is described below as an example of a network device. The method comprises the following steps:
the network device determines a broadcast message and transmits the broadcast message, wherein the broadcast message includes first information including first measurement information of a positioning reference signal.
In a possible implementation, the broadcast message is a posSIB) such as posSibType6-1, or a newly defined posSIB. Alternatively, the broadcast message is a system information block, such as SIB11, or other possible system information, such as a newly defined SIB.
In a possible implementation, the first information includes first indication information indicating that at least one set of measurement information in the first measurement information is used for the terminal device in the non-connected state, or the first indication information indicates that the terminal device in the non-connected state is allowed to request at least one set of measurement information in the first measurement information.
In a possible implementation, the first information includes second indication information for indicating that the request for second measurement information is allowed, the second measurement information being different from the first measurement information.
In a possible implementation manner, the method further includes: the network device transmits second information comprising third measurement information of the positioning reference signal.
In a possible implementation manner, the method further includes: the network device receives a request message sent by the terminal device, the request message being usable for requesting activation of at least one set of measurement information of the first measurement information and/or the request message being usable for requesting at least one set of measurement information of the second measurement information.
In a possible implementation manner, the method further includes: the network device sends a response message to the terminal device, wherein the response message comprises at least one set of measurement information in the first measurement information and/or at least one set of measurement information in the second measurement information, or the response message is used for indicating to activate at least one set of measurement information in the first measurement information.
In a possible implementation, the first measurement information includes one or more of the following: measurement configuration information of a positioning reference signal, an ID of the measurement configuration information, region information associated with the measurement configuration information, measurement configuration priority information, third indication information, or frequency point information associated with the measurement configuration information. Wherein the measurement configuration information of the positioning reference signal comprises measurement interval configuration information and/or measurement processing window configuration information. The third indication information is used for indicating whether the terminal equipment is allowed to request to activate or deactivate the measurement information of the positioning reference signal.
In a possible implementation, the request message includes one or more of the following that the measurement information is associated with: ID. Region information, priority information, frequency point information, or fourth indication information for indicating that measurement information not belonging to the first measurement information is requested.

In a possible implementation manner, the request message is a message 1 in the random access process, and the response message is a message 4 in the random access process; or the request message is a message A in the random access process, and the response message is a message B in the random access process; or the request message is a pre-configuration authorization request message, and the response message is a pre-configuration authorization response message.

Detailed Description
In order to facilitate understanding of the technical solutions provided by the embodiments of the present application, first, some technical terms related to the embodiments of the present application are explained.
1) The (radio) access network device (radio access network, (R) AN), which may also be referred to as AN access device, is capable of managing radio resources, providing access services for the user equipment, and completing forwarding of user equipment data between the user equipment and the core network, and may also be understood as a base station in the network.
The access network device in the embodiment of the present application may be any communication device with a wireless transceiver function for communicating with the user equipment. Such access network devices include, for example, but are not limited to: an evolved Node B (eNB), a radio network controller (radio network controller, RNC), a Node B (Node B, NB), a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS), a home evolved Node B, heNB, or home Node B, HNB), a Base Band Unit (BBU), an Access Point (AP) in a wireless fidelity (wireless fidelity, WIFI) system, a wireless relay Node, a wireless backhaul Node, a transmission point (transmission point, TP), or a transmission reception point (transmission and reception point, TRP), etc., may also be 5G, such as a next generation Node B (next generation Node B, gNB) in an NR system, or a transmission point (TRP or TP), an antenna panel of one or a group (including a plurality of antenna panels) of a base station in a 5G system, or may also be a network Node constituting a gNB or a transmission point, such as a distributed unit (BBU), or a distributed unit (baseBand), etc. In a 5G core network based positioning architecture, the gNB/ng-eNB may provide measurement information for the target user equipment and communicate this information to the positioning management device.
In some deployments, the gNB may include a Centralized Unit (CU) and DUs. The gNB may also include an active antenna unit (active antenna unit, AAU). The CU implements part of the functionality of the gNB and the DU implements part of the functionality of the gNB. For example, the CU is responsible for handling non-real time protocols and services, implementing the functions of the radio resource control (radio resource control, RRC), packet data convergence layer protocol (packet data convergence protocol, PDCP) layer. The DUs are responsible for handling physical layer protocols and real-time services, implementing the functions of the radio link control (radio link control, RLC), medium access control (media access control, MAC) and Physical (PHY) layers. The AAU realizes part of physical layer processing function, radio frequency processing and related functions of the active antenna. The information of the RRC layer is generated by the CU and finally becomes PHY layer information through PHY layer encapsulation of DU, or is converted from the information of the PHY layer. Thus, under this architecture, higher layer signaling, such as RRC layer signaling, may also be considered to be sent by DUs, or by dus+aaus. It is understood that the access network device may be a device comprising one or more of a CU node, a DU node, an AAU node. In addition, the CU may be divided into access network devices in an access network (radio access network, RAN), or may be divided into access network devices in a Core Network (CN), and the access network devices may be next-generation radio access networks (NG-generation radio access network, NG-RAN), which is not limited in this aspect of the present application.
In the embodiment of the present application, the means for implementing the function of the access network device may be the access network device, or may be a means capable of supporting the access network device to implement the function, for example, a chip system, and the apparatus may be installed in the access network device. In the technical solution provided in the embodiment of the present application, the description will be given taking, as an example, that the apparatus for implementing the function of the access network device is the access network device.
2) A terminal device, which may also be referred to as a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device that provides voice and/or data connectivity to a user. For example, the terminal device may include a handheld device having a wireless connection function, an in-vehicle device, and the like. Currently, the terminal device may be: a mobile phone, a tablet, a notebook, a palm, a mobile internet device (mobile internet device, MID), a wearable device, a Virtual Reality (VR) device, an augmented reality (augmented reality, AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned (self-driving), a wireless terminal in teleoperation (remote medical surgery), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city (smart city), or a wireless terminal in smart home (smart home), and the like.
By way of example, and not limitation, in embodiments of the application, the terminal device may also be a wearable device. The wearable device can also be called as a wearable intelligent device or an intelligent wearable device, and is a generic name for intelligently designing daily wear and developing wearable devices, such as glasses, gloves, watches, clothes, shoes, and the like, by applying wearable technology. The terminal device may also include a relay (relay), for example, the terminal device may be a customer terminal device (customer premise equipment, CPE) that may receive signals from the network device and forward the signals to other terminal devices. Or it is understood that all that is capable of data communication with a base station can be seen as a terminal device. The various terminal devices described above, if located on a vehicle (e.g., placed in a vehicle or installed in a vehicle), may be considered as in-vehicle terminal devices, also referred to as in-vehicle units (OBUs), for example.
In addition, in the embodiment of the present application, the terminal device may refer to a device for implementing a function of the terminal device, or may be a device capable of supporting the terminal device to implement the function, for example, a chip system, and the device may be installed in the terminal device. For example, the terminal device may also be a vehicle detector. In the embodiment of the application, the chip system can be composed of chips, and can also comprise chips and other discrete devices. In the technical solution provided in the embodiment of the present application, the device for implementing the function of the terminal device is described by taking the terminal device as an example.
3) The location management device, also called location management network element, is mainly responsible for location management. For example, the location management device receives location requests of other network elements (such as access and mobility management network elements), collects location data of the user, and obtains the user position after location calculation. The location management network element can also manage and configure the base station or the location management unit, so as to realize the configuration of the location reference signals and the like. The name of the positioning management device is not limited in the embodiment of the present application, and for example, the positioning management device may also be called a positioning device, a location server, a positioning service center, a positioning processing center, or the like. The location management device to which embodiments of the present application relate may be a location management function (location management function, LMF) or a location management component (location management component, LMC), or may be a home location management function (local location management function, LLMF) located in an access network device, or other network elements having similar functionality, etc. For convenience of description, the following embodiments are described by taking the LMF as an example of the location management device.
In a 5G core network based positioning architecture, the LMF network element may be responsible for supporting different types of location services related to the target UE, including positioning of the UE and delivery of assistance data to the UE, the control plane and user plane of which are an evolved serving mobile location center (evolved serving mobile location centre, E-SMLC) and a serving positioning protocol (service location protocol, SLP), respectively. The LMF network element can perform the following information interaction with the ng-eNB/gNB and the UE:
Information interaction is performed between the cell location protocol A (NR positioning protocol A, NRPPa) and the next generation evolved node B (next generation evolved nodeB, ng-eNB)/gNB through NR location protocol A (NR positioning protocol A, NRPPa) information, such as PRS (radio resource control) acquisition, sounding reference signal (sounding reference signal, SRS) configuration information, cell timing, cell location information and the like;
UE capability information transfer, auxiliary information transfer, measurement information transfer, and the like are performed with the UE through LTE positioning protocol (LTE positioning protocol, LPP) messages.
4) Positioning methods, which are classified into the following three types according to the source of the positioning reference signal (positioning reference signal, PRS): a downlink positioning method, an uplink positioning method and an uplink and downlink combined positioning method. It should be noted that, here, uplink and downlink are relatively speaking, and if the transmission direction from the network device to the terminal device is downlink (this is taken as an example here), the transmission direction from the terminal device to the network device is uplink. Conversely, if the network device to terminal device transmission direction is upstream, then the terminal device to network device transmission direction is downstream.
In the downlink positioning method, a terminal device measures a downlink positioning reference signal (downlink positioning reference signal, DL-PRS) sent by a network side. And the terminal equipment estimates the position of the terminal equipment according to the measurement result, and realizes downlink positioning.
In the uplink positioning method, a network device measures an uplink positioning reference signal (uplink positioning reference signal, UL-PRS) sent by a terminal device. And the network equipment estimates the position of the terminal equipment according to the measurement result, and uplink positioning is realized. The uplink positioning reference signal may be an SRS, or other reference signal that may be used for uplink measurements. The embodiment of the present application is not limited thereto. For example, the SRS may be an uplink reference signal (MIMO-SRS) for multiple-input multiple-output (MIMO). The SRS may also be an uplink positioning reference signal (pos-SRS) dedicated for positioning.
The network equipment measures the uplink positioning signal from the terminal equipment and the terminal equipment measures the downlink positioning reference signal from the network equipment. The position of the terminal device is estimated based on the measurement results of the network device and the measurement results of the terminal device.
5) The data advance transmission (early data transmission, EDT) is applicable to the uplink transmission of the terminal equipment in the non-connection state. EDT may be applied, for example, to the uplink transmission of terminal devices in the idle state. It will be appreciated that the terminal device in idle state is allowed to EDT during random access and then to perform a corresponding downlink data transmission. Can be applied to NB-IoT, enhanced coverage area (enhanced coverage), low bandwidth and low complexity (bandwidth reduced low complexity) scenarios.
6) The Pre-configured uplink resource (Pre-configuration uplink resource, PUR) can be suitable for uplink transmission of non-connected terminal equipment. For example, PUR may be applied to uplink transmissions of terminal devices in an idle state. The terminal equipment in idle state is allowed to use the preconfigured uplink resource for uplink transmission once without initiating a random access procedure. The same applies to NB-IoT, enhanced coverage area, low bandwidth, low complexity scenarios.
7) Packet data transmission (small data transmission, SDT) is applicable to uplink transmissions of non-connected terminal devices. For example, PUR may be applied to uplink transmissions of terminal devices in an inactive state. For example, a terminal device in an inactive state initiates a random access procedure, in msg3/msgA, packet data is allowed to be transmitted together with radio resource control (radio resources control, RRC) signaling. For another example, the terminal device in the inactive state transmits packet data on the configured grant resources, and the first uplink message requires that the uplink data be transmitted together with the RRC resume request message.
8) Measurement configuration information of positioning reference signals (positioning reference signal, PRS) includes Measurement Gap (MG) configuration information and PRS processing window (PRS processing window, PPW) configuration information. The configuration information of the PPW is also referred to herein as positioning reference signal processing window configuration information or measurement processing window configuration information.
It will be appreciated that if the terminal device has only one set of radio frequency channels, it is not supported to receive signals on different frequency bands while transceiving signals on the serving cell. In other words, if the terminal device uses one radio frequency module to perform measurement and transmit and receive signals, the terminal device does not support to operate at two different frequency points at the same time. In this case, the terminal device needs to measure the signal received on the inter-frequency point by means of gap measurement. And stopping signal receiving and transmitting on the service cell in the gap by the terminal equipment, adjusting the radio frequency channel to the different frequency point, and receiving signals of the different frequency adjacent cell. And after the gap time is over, the radio frequency channel is switched to the frequency point of the current cell.
The gap may be configured by the network device, i.e., the network device may configure the MG. The configuration parameters of the MG include one or more of the following: measurement interval repetition period (measurement gap repetition period, MGRP), measurement offset (gapOffset), measurement length (measurement gap length, MGL), or measurement timing advance (measurement gap timing advance, MGTA). Wherein MGRP is used to configure the period of the gap, for example 4ms, 20ms, 80ms or 160ms. gapOffset is used to configure the start position of the gap. Starting from the initial subframe in the period, the value set of the measurement offset is {0,1, …, MGRP-1}. For example, mgrp=160 ms, and the measurement offset has 160 values. For another example, mgrp=20 ms, and the set of values of the measurement offset is {0,1, …,19}. The MGL is used to configure the length of the gap, e.g., the MGL may be 1.5ms, 3ms, 3.5ms, 4ms, 5.5ms, or 6ms. If MGTA is configured, measurement gap starts to measure MGTA ms before gap sub-frame appears, i.e. measurement gap ends from time gap ms to last sub-frame appears before. MGTA is 0.25ms or 0.5ms.
It is appreciated that when the terminal device does not switch BWPs, the access network device may not accurately detect PRSs if the PRS is measured outside the MG, which may collide with other signals or channels, for which reason priority of the PRS and other signals (or channels) may be considered.
9) The RRC state of the terminal device, NR supports 3 RRC states including rrc_idle (also called IDLE state), rrc_inactive (also called deactivated state) and rrc_connected (also called CONNECTED state). In contrast to rrc_connected, rrc_idle and rrc_inactive are also referred to as unconnected states. In the embodiment of the application, the terminal equipment in the connection state refers to the terminal equipment in the RRC_CONNECTED, and the terminal equipment in the non-connection state refers to the terminal equipment in the RRC_IDLE or RRC_INACTIVE.
10 System information (system information, SI) for the terminal device to access the cell. It can be understood that after the terminal device acquires downlink synchronization with the cell through cell search, the SI of the cell is acquired so as to access the cell and operate normally in the cell. The SI mainly comprises: master information block (master information block, MIB), system information block (system information block, SIB), and so on. Among them, a plurality of types of SIBs are defined, for example, from SIB type (type) 1 to SIB type 14, simply called SIB1, SIB2, …, SIB14, respectively. SIBs other than SIB1 are also known as other system information (other system information, OSI). The SI also includes a positioning system information block (positioning system information block, posSIB). The SIB associated with an embodiment of the present application is briefly described. For example, the MIB includes cell barring status information and basic physical layer information associated with the received SIB 1. SIB1 defines the scheduling of other system information blocks and contains information needed for initial access. SIB11 contains information related to measurement in a non-connected state (e.g., inactive state or idle state). The posSIB is dedicated to broadcast positioning related assistance data, including positioning reference signal related assistance data.
11 "at least one" means one or more, and "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a alone, a and B together, and B alone, wherein a, B may be singular or plural. The character "/" generally indicates 44. The context-dependent object is an "or" relationship. "at least one item(s)" or the like below refers to any combination of these ten or more items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b, or c may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or plural.
And, unless specified to the contrary, references to "first," "second," etc. ordinal words of embodiments of the present application are used for distinguishing between multiple objects and are not used for limiting the order, timing, priority, or importance of the multiple objects. For example, the first information and the second information are only different from each other in order to distinguish different information or different manners of transmitting information, and are not different in priority, transmission order, importance, or the like.
The foregoing describes certain technical terms related to the embodiments of the present application, and the following describes matters related to the embodiments of the present application.
In order to reduce the positioning time delay, the access network device pre-configures the measurement information of the MG and/or the measurement information of the PPW for each terminal device, and when the terminal device needs to perform positioning measurement, the corresponding measurement configuration can be requested to the access network device, so that the signaling cost is high and the time delay is also high. In addition, the access network device uses RRC signaling to preconfigure measurement information of the MG and/or measurement information of the PPW, and cannot preconfigure the terminal device in the non-connected state, so that positioning of the terminal device in the non-connected state cannot be achieved.
In view of this, a solution of an embodiment of the present application is provided. In the embodiment of the application, the measurement information of the positioning reference signal can be sent in a broadcast mode, so that a plurality of terminal devices can acquire the measurement information of the positioning reference signal by receiving broadcast messages. When the terminal equipment needs to execute the measurement positioning reference signal, the terminal equipment can request corresponding measurement information from the network equipment, thereby realizing the positioning of the terminal equipment. According to the scheme provided by the embodiment of the application, the measurement information of the positioning reference signals is sent in a broadcasting mode, so that the network equipment can simultaneously pre-configure the measurement information of the positioning reference signals for a plurality of terminal equipment. Compared with the network equipment which respectively and independently pre-configures the measurement information of the positioning reference signals for each terminal equipment, the signaling overhead for configuring the measurement information of the positioning reference signals can be reduced. In addition, the measurement information of the positioning reference signal can be carried in the system information, and the non-connection state terminal equipment can acquire the measurement information of the positioning reference signal without entering a connection state, so that the positioning of the non-connection state terminal equipment can be realized.
The scheme provided by the embodiment of the application can be applied to various communication systems, such as: LTE systems, 5G systems, such as New Radio (NR) systems, or next generation communication systems, such as 6G systems, etc. Of course, the technical solution of the embodiment of the present application may also be applied to other communication systems, as long as the communication system has a positioning requirement for the terminal. In addition, the communication system may be also suitable for future communication technologies, and the system described in the embodiment of the present application is for more clearly describing the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art can know that, with the evolution of the network architecture, the technical solution provided in the embodiment of the present application is also suitable for similar technical problems.
Fig. 1 is a schematic diagram of a positioning architecture of a communication system to which an embodiment of the present application is applied, as shown in fig. 1, a network element/module mainly includes three parts, namely a next generation radio access network (next generation radio access network, NG RAN), a terminal device and a core network. The core network includes LMF, access and mobility management functions (access and mobility management function, AMF), SLP, and E-SMLC, among others. The location server, i.e. the location management function (location management function, LMF), is connected to the AMF, and the LMF and the AMF are connected through NLs interfaces. The LMF is responsible for supporting different types of location services for the terminal, including locating the terminal and communicating assistance data to the terminal. The AMF may receive a location service request associated with a terminal from a 5th generation core network location services (5th generation core network location services,5GC LCS) entity or the AMF itself may initiate some location services on behalf of a particular terminal and forward the location service request to the LMF. And after the position information returned by the terminal is obtained, the related position information is returned to the 5GC LCS entity.
The NG RAN may include a next generation node B (next generation node B, gNB), a next generation evolved base station (next generation evolved nodeB, NG-eNB), or a future evolved network node, among others. The gNB and the NG-eNB are connected through an Xn interface, and the LMF is connected with the NG-eNB/gNB through an NG-C interface.
It should be understood that fig. 1 is an exemplary illustration of a communication system applicable to an embodiment of the present application, and is not limited to the type, number, connection manner, etc. of network elements included in the communication system applicable to the present application.
For example, fig. 2 shows a network architecture of a communication system including a core network, NG-RAN, and terminals to which embodiments of the present application are applicable. The core network includes network elements/modules such as LMF, AMF, secure user plane location (secure user plane location, SUPL) location platform (SUPL location platform, SLP) and E-SMLC, and the NG RAN includes network elements/modules such as gNB, NG-eNB, where specific functions of the network elements/modules such as LMF, AMF, SLP, E-SMLC, gNB and NG-eNB, and connection relationships between the network elements/modules may be referred to the description of relevant portions of fig. 2 above, and are not repeated herein.
Unlike fig. 1, the network architecture shown in fig. 2 has an LMC added to the NG-RAN, and the LMC is specifically deployed inside the base station, for example, in the gNB or in the NG-ENB. In such a network architecture, the LMC serves as a function internal to the base station, and thus no new interface needs to be introduced.
Fig. 3 shows a network architecture of another communication system to which an embodiment of the present application is applied, as shown in fig. 3, the communication system also includes a core network, NG-RAN and a terminal. In contrast to fig. 2, the LMC in the network architecture shown in fig. 3 acts as a separate logical node in the NG-RAN and is connected to the base station via a new interface, e.g. in fig. 3, the LMC is connected to the gNB-CU via interface Itf.
Fig. 4 shows a network architecture of yet another communication system to which an embodiment of the present application is applied, as shown in fig. 4, where the communication system also includes a core network, an NG-RAN and a terminal, and the LMC is used as an independent logical node in the NG-RAN, unlike fig. 3, in which the LMC can be simultaneously connected to a plurality of base stations through a new interface in fig. 4. Fig. 4 illustrates an example in which an LMC is connected to two base stations simultaneously, and in an implementation, the LMC may be connected to more base stations.
Fig. 1 to fig. 4 are exemplary illustrations of a communication system to which the embodiments of the present application are applicable, and the types, numbers, connection manners of network elements, etc. included in the communication system to which the present application is applicable are not specifically limited. And the network elements/modules illustrated by dashed lines in fig. 1-4 are not necessarily optional, e.g., E-SMLC or SLP are not essential; alternatively, the network element/module illustrated by the dashed line is another form of presence, e.g. a gNB or ng-eNB, also referred to as TRP in some embodiments, and the terminal device is referred to as a secure user plane location (secure user plane location, SUPL) enabled terminal (SUPL enabled terminal, SET) in some embodiments.
The communication method provided by the embodiment of the application can be applied to positioning of the terminal equipment. Such as uplink positioning, downlink positioning, and uplink and downlink positioning. It should be noted that, here, uplink and downlink are relatively speaking, and if the transmission direction from the network device to the terminal device is downlink (this is taken as an example here), the transmission direction from the terminal device to the network device is uplink; conversely, if the network device to terminal device transmission direction is upstream, then the terminal device to network device transmission direction is downstream.
The following describes the scheme provided by the embodiment of the application in detail with reference to the accompanying drawings. It should be noted that, in the drawings corresponding to the embodiments of the present application, all steps indicated by dotted lines are optional steps. The embodiment of the application takes measurement of the positioning reference signal as an example, but is not limited to the positioning reference signal, that is, the embodiment of the application can be also applied to measurement of other reference signals. Other reference signals include, for example, synchronization signals and physical broadcast channel blocks (synchronization signal and PBCH block, SSB). In uplink positioning, the "positioning reference signal" is also referred to as "uplink reference signal", "uplink positioning reference signal", or the like. In the downlink positioning, the "positioning reference signal" is also referred to as "downlink reference signal", "downlink positioning reference signal", or the like. It is also understood that "uplink reference signal", "uplink positioning reference signal" and "positioning reference signal" all represent uplink reference signals for positioning. "downlink reference signal", "downlink positioning reference signal" and "positioning reference signal" all represent downlink reference signals for positioning. Hereinafter, it is not clearly distinguished.
In the following description, this method is exemplified as applied to the communication system shown in any one of fig. 1 to 4. It should be noted that the embodiments of the present application are merely examples of the communication system shown in fig. 1-4, and are not limited to such a scenario. In addition, the method relates to an access network device and a terminal device, and may also relate to a location management device, and the like, hereinafter, taking the location management device as an example of an LMF network element, it should be understood that in future communications, such as 6G, the location management device may still be an LMF network element, or have other names, and the embodiments of the present application are not limited. In addition, the access network device may be an access network device currently serving the terminal device. The access network device may be a device in an NG RAN, e.g., a gNB, NG-eNB. Alternatively, the access network device may be an LMC. As described above, if the LMC is a function within the access network device, the access network device is the access network device where the LMC is located. If the LMC is deployed as in fig. 3 or fig. 4, i.e. the LMC is connected as a separate logical node to a network device or a plurality of access network devices through interfaces, the access network device is any access network device connected to the LMC. The following is an example of application of the communication method provided by the embodiment of the present application to downlink positioning.
Fig. 5 is a flowchart of a communication method according to an embodiment of the present application. The specific flow of the communication method comprises the following steps.
S501, the network equipment sends a broadcast message, and correspondingly, the terminal equipment receives the broadcast message from the network equipment.
The broadcast message includes first information including first measurement information of a positioning reference signal. The network device transmits the broadcast message, it may also be considered that the network device transmits the first information in a broadcast manner, or the network device transmits the first measurement information in a broadcast manner.
The network device transmits the first measurement information in a broadcast manner, and it can be considered that the network device transmits measurement information related to the positioning reference signal in advance. For example, the network device transmits measurement information related to the positioning reference signal to the terminal device or the positioning management device in advance. From this point of view, the first measurement information may be considered as measurement information of a positioning reference signal preconfigured by the network device. It should be understood that "pre-configuration" refers to the network transmitting measurement information related to the positioning reference signal to the terminal device or the positioning management device in advance. The terminal device or the positioning management device may request activation or deactivation of the preconfigured measurement information from the access network device according to the requirements. Accordingly, the network may activate or deactivate the pre-configured measurement information by signaling or messaging in response to a request from the terminal device or the location management device. For example, the network may activate or deactivate the preconfigured measurement information through signaling or messages such as Downlink (DL) MAC Control Element (CE), RRC, etc.
The network device may configure one set of pre-configuration information for the positioning reference signal, and may also configure multiple sets of pre-configuration information for the positioning reference signal. I.e. the first measurement information may comprise at least one set of pre-configured measurement information. The preconfigured measurement information, which may also be referred to as measurement preconfiguration information, i.e. the first measurement information comprises at least one set of measurement preconfiguration information. The set of measurement preconfiguration information may include one or more preconfigured measurement parameters. The measurement parameters, for example, include offset of MG/PPW, start time slot, duration, period, timing advance information of MG, cell and subcarrier spacing information of PPW, etc., and reference may be made to the relevant content in the foregoing technical term 8), which is not repeated here. Alternatively, the first measurement information may include one or more of the following: at least one set of pre-configured measurement information, at least one set of measurement information, at least one pre-configured measurement parameter, at least one measurement parameter. For convenience of description, the embodiment of the present application takes an example that the first measurement information includes one or more sets of measurement information. It is also contemplated that at least one set of pre-configured measurement information, at least one set of measurement information, at least one pre-configured measurement parameter, at least one measurement parameter, collectively referred to as one or more sets of measurement information. The contents included with respect to each set of measurement information will be described below.
Since the first measurement information of the positioning reference signal is transmitted in a broadcast manner, the network device can simultaneously pre-configure the measurement information of the positioning reference signal for a plurality of terminal devices. Compared with the network equipment which pre-configures the measurement information of the positioning reference signals for each terminal equipment, the signaling overhead for configuring the measurement information of the positioning reference signals can be reduced, and the positioning time delay is reduced.
Alternatively, the broadcast message may be a system message (or system information), that is, measurement information for configuring the positioning reference signal may be carried in the system message, so that the terminal device can acquire the measurement information of the positioning reference signal when receiving the system message. In this way, the terminal device can send the positioning reference signal to the network device after obtaining the measurement information, without entering the connection state, or the terminal device can send the positioning reference signal to the network device without entering the connection state. Thus, even the terminal device in the disconnected state can realize positioning.
For example, the broadcast message may be SIB11, and the first measurement information may be included in an information element (information element, IE) existing in SIB11, or an IE may be added to SIB11 to carry the first measurement information. Since SIB11 contains information related to measurement in a non-connection state (for example, in a non-active state or in an idle state), positioning for the terminal device in the non-connection state can be achieved by carrying measurement information of a positioning reference signal applicable to the terminal device in the non-connection state by SIB 11. The signaling for carrying the measurement information of the positioning reference signal applicable to the terminal equipment in the non-connected state is not required to be additionally transmitted by the network equipment, so that the signaling overhead can be saved. Of course, the broadcast message may also be a newly defined SIB, e.g. the broadcast message may be SIBx, where x is an integer greater than 14. In addition, the access network equipment can sense the content of the measurement information carried by the SIB11, so that corresponding resource scheduling can be effectively carried out.
For another example, the broadcast message may be a posSIB, and the first measurement information may be included in an IE existing in the posSIB, or an IE may be added in the posSIB to carry the first measurement information. Since the posSIB is dedicated to broadcasting positioning related assistance data (provide assistance data) and the measurement information of the positioning reference signal belongs to positioning assistance data, the same measurement information can be broadcast simultaneously for a plurality of cells by carrying the first measurement information through the posSIB. The posSIB carries the first measurement information, that is, the first measurement information is sent to the terminal device in a form of providing auxiliary data, and no additional signaling for carrying the first measurement information is required to be sent by the network device, so that signaling overhead can be saved. In addition, the terminal equipment in a non-connection state, for example, the terminal equipment in an idle state or a non-activation state, can acquire measurement information of the positioning reference signal by receiving the posSIB, and then perform positioning measurement. Namely, the terminal equipment can perform positioning measurement without entering a connection state, so that the positioning of the terminal equipment in a non-connection state can be realized, and the method is particularly suitable for a moving scene of the terminal equipment.
Optionally, the broadcast message is posSibType6-1, i.e. includes assistance data related to the downlink positioning reference signal. Of course, the broadcast message may also be a newly defined posSIB.
In general, all sets of measurement information included in the first measurement information may be used for terminal devices in the RRC connected state, but it is possible that some set or sets of measurement information included in the first measurement information cannot be used for terminal devices in the non-connected state. I.e. part of the set of measurement information in the first measurement information is available for the terminal device in the non-connected state. For example, the first measurement information includes M sets of measurement information, wherein N sets of measurement information among the M sets of measurement information are available for the non-connection sleeve terminal device. The M-N sets of measurement information other than the N sets of measurement information cannot be used for the terminal device in the non-connected state. It is understood that M and N are both positive integers, and N is less than or equal to M. If the terminal device in the disconnected state requests one or more of the M-N sets of measurement information from the network device, it is obvious that the terminal device fails. For this reason, in the embodiment of the present application, the first information may further indicate whether one or more sets of measurement information in the first measurement information are available for the terminal device in the non-connected state, or it may be understood that the first information may further indicate whether the terminal device in the non-connected state is allowed to request one or more sets of measurement information in the first measurement information, or the first information may further indicate whether the terminal device in the non-connected state may request one or more sets of measurement information in the first measurement information. The terminal equipment in the non-connection state can clearly request which set or sets of measurement information according to the indication of the first information, so that the probability of failure of the request is reduced, unnecessary requests can be prevented from being sent by the terminal equipment in the non-connection state, and the transmission cost is saved.
As an example, the first information may include first indication information, which may indicate whether at least one set of measurement information among the first measurement information is used for the terminal device in the non-connected state. It should be understood that the first measurement information may be used for the terminal device in the connected state. That is, the first indication information is only for the terminal device in the non-connected state. From this point of view, it can also be considered that the first indication information may indicate that at least one set of measurement information among the first measurement information is used for the terminal device in the non-connected state. The terminal device in the non-connected state may consider that the at least one set of measurement information may be used without being acquired by means of a request. I.e. the terminal device in the non-connected state, can use the at least one set of measurement information without request.
For example, the first indication information may indicate whether the measurement information is available for the terminal device in the non-connected state by the value of a bit corresponding to the measurement information. For example, the first measurement information includes M sets of measurement information, and the first indication information may include M bits, where the M bits correspond to the M sets of measurement information one by one. If a certain set of measurement information in the M sets of measurement information cannot be used for the terminal equipment in a non-connection state, the value of the bit corresponding to the set of measurement information can be 0; in contrast, a certain set of measurement information in the M sets of measurement information may be used for a terminal device in a non-connected state, and the bit corresponding to the set of measurement information has a value of "1". Or if a certain set of measurement information in the M sets of measurement information cannot be used for the terminal equipment in a non-connection state, the value of the bit corresponding to the set of measurement information can be 1; in contrast, a certain set of measurement information in the M sets of measurement information may be used for a terminal device in a non-connected state, and the bit corresponding to the set of measurement information has a value of "0". Optionally, the correspondence between the N configuration parameters and the N bits may be preset by a protocol, or indicated by the network device; alternatively, the first indication information may occupy 1 bit to indicate that all M sets of measurement information can be used for the terminal device in the non-connected state. For example, the 1-bit value is "0", indicating that M sets of measurement information can be used for the terminal device in the non-connected state. Or the 1 bit takes a value of "1", which indicates that the M sets of measurement information can be used for the terminal equipment in the non-connection state.
As another example, the first indication information may also indicate whether or not the terminal device in the non-connected state is allowed to request at least one set of measurement information among the first measurement information. Alternatively, the first indication information indicates that the terminal device in the non-connected state is allowed to request at least one set of measurement information among the first measurement information. Alternatively, the first indication information indicates that the terminal device in the non-connected state may request at least one set of measurement information among the first measurement information. The terminal equipment in the non-connection state can definitely request the partial measurement information according to the first indication information, so that the terminal equipment in the subsequent non-connection state can request the partial measurement information to avoid sending unnecessary requests.
It should be noted that, the first indication information may indicate whether at least one set of measurement information in the first measurement information is used for the terminal device in the non-connected state, and whether the terminal device in the non-connected state is allowed to request at least one set of measurement information in the first measurement information.
Although the network device is preconfigured with the first measurement information, the network device may also support measurement information other than the first measurement information, e.g. the second measurement information. It is also understood that the second measurement information does not belong to the first measurement information or that the second measurement information is different from the first measurement information. Similar to the first measurement information, the second measurement information may also include one or more of the following: at least one set of pre-configured measurement information, at least one set of measurement information, at least one pre-configured measurement parameter, at least one measurement parameter. For convenience of description, the embodiment of the present application takes the example that the second measurement information includes one or more sets of measurement information.
The second measurement information may be completely different from the first measurement information. For example, the first measurement information may be MG configuration information, and the second measurement information may be PPW configuration information. For another example, the first measurement information includes measurement information 1-measurement information 4 and the second measurement information includes measurement information 5-measurement information 6. The second measurement information may also be partially identical to the first measurement information, that is, measurement information outside the range of the first measurement information may include measurement information not belonging to the first measurement information and measurement information partially belonging to the first measurement information. For example, the first measurement information includes measurement information 1-measurement information 4 and the second measurement information includes measurement information 3-measurement information 5. If the network device does not support the terminal device to request the second measurement information, the terminal device still requests the second measurement information from the network device, and it may be considered that the request sent by the terminal device to the network device is unnecessary, which may cause additional signaling overhead. Therefore, in the embodiment of the present application, the first information may further indicate whether the network device supports the terminal device to request measurement information other than the first measurement information. For example, the first information may include second indication information indicating that the second measurement information is allowed to be requested, or the second indication information indicating that the second measurement information is not allowed to be requested. I.e. the second indication information may indicate whether or not to allow requesting measurement information not belonging to the first measurement information. The terminal device may determine, according to the second indication information, whether to request the second measurement information from the network device if the first measurement information does not meet the requirement. For example, the second indication information indicates that the request for the second measurement information is allowed, and the terminal device may request the second measurement information in a case where the first measurement information does not satisfy the measurement requirement, thereby satisfying the positioning performance requirement as much as possible. Unnecessary requests can be avoided from being sent by the terminal equipment, and signaling overhead and power consumption of the terminal equipment are reduced.
Specifically, the set of measurement information included in the first measurement information may include one or more of the following: measurement configuration information of a positioning reference signal, an ID of the measurement configuration information, region information associated with the measurement configuration information, measurement configuration priority information, third indication information, or frequency point information associated with the measurement configuration information.
Wherein the measurement configuration information of the positioning reference signal may comprise measurement interval configuration information and/or measurement processing window configuration information. The measurement interval configuration information and/or the measurement processing window configuration information may refer to the foregoing, and will not be described herein. The ID of the measurement configuration information is used to identify the measurement configuration information. It should be noted that the positioning management device and the access network device each maintain multiple sets of measurement configurations, and the mapping rules between the IDs of the multiple sets of measurement configurations and the measurement configurations may be the same or different at the positioning management device and the access network device. In order to make the identification of the measurement configuration information by the access network device and the positioning management device consistent, the positioning management device and the access network device can interact the mapping rule information between the ID of the measurement configuration information and the measurement configuration through the NRPPa flow, so that the access network device and the positioning management device can accurately determine the measurement configuration information requested by the subsequent terminal device.
The area information associated with the measurement configuration information is, for example, a cell associated with the measurement configuration information, or a cell list associated with the measurement configuration information, or an area within one cell associated with the measurement configuration information. The measurement configuration priority information may indicate a priority of measurement configuration of the plurality of sets of positioning reference signals, thereby requesting measurement information for the terminal device, or requesting activation of measurement information for the terminal device, or providing a reference for the terminal device when using the measurement information, so as to improve positioning performance as much as possible. The frequency point information associated with the measurement configuration information may support measurement of positioning reference signals of a plurality of frequency points, for example, so that the terminal device may determine measurement information of positioning reference signals of which frequency points are requested according to the frequency point information associated with the measurement configuration information.
The third indication information may be used to indicate whether the terminal device is allowed to request measurement information for activating or deactivating the positioning reference signal. It is also understood that the third indication information may be used to indicate a request manner in which the terminal device requests measurement information of the positioning reference signal. The third indication information can explicitly inform the terminal device whether the terminal device can request to activate or deactivate the measurement configuration information of the positioning reference signal, so as to avoid the terminal device from sending unnecessary requests. For example, the third indication information indicates that the terminal device can use the relevant measurement information without a request, and the terminal device does not need to initiate a request. For another example, the third indication information indicates measurement information allowing the terminal device to request activation of the positioning reference signal, and the terminal device may request the network device for measurement information activating the positioning reference signal. The third indication information is carried in the first measurement information, so that the network device does not need to additionally send signaling for indicating whether to allow the terminal device to request to activate or deactivate the measurement configuration information of the positioning reference signal, and signaling overhead can be saved.
S502, the network equipment sends second information to the terminal equipment, and correspondingly, the terminal equipment receives the second information from the network equipment.
The second information may include third measurement information of the positioning reference signal. The network device sends the second information, which may also be considered as a unicast message. The third measurement information may also be considered to be location related measurement information that the network device sends to the specific terminal device via unicast messages. For example, the third measurement information may be measurement information configured by the network device, measurement information activated by the network device, or positioning assistance information. It should be understood that the network device activated measurement information belongs to the network device preconfigured measurement information. If the network device is an access network device, the access network device may send the second information to the terminal device through RRC signaling, i.e. the second information is carried in the RRC signaling. If the network device locates the management device, the location management device may send the second information via an LPP message. For example, the second information may be carried in an LPP provisioning assistance data message. That is, the location management device sends the second information to the terminal device, it may be considered that the location management device sends LPP ProvideAssistanceData message to the terminal device, the LPP ProvideAssistanceData message may include the second information, or the LPP ProvideAssistanceData message may include the third measurement information.
When the network device configures the first measurement information and the third measurement information at the same time, the terminal device may perform positioning measurement according to the first information and/or the second information. I.e. the terminal device can request or use more suitable measurement information from the network according to the requirements. For example, when the third measurement information includes measurement information related to positioning of the terminal device, the terminal device may preferentially perform positioning measurement according to the second information. Because the third measurement information is configured by the network for the specific terminal equipment (the specific terminal equipment can be used without activation), the specific terminal equipment can be considered to be preferentially used for positioning measurement according to the second information, so that the measurement requirement can be better met, the first measurement information is not required to be requested, and the transmission cost is saved. Of course, the terminal device may also perform positioning measurement according to the first information and the second information, which is not limited in the embodiment of the present application.
For another example, when the third measurement information includes pre-configured measurement information or assistance information related to the positioning of the terminal device, the terminal device may request measurement information from the network or request activation of measurement information in accordance with the second information. Since the third measurement information is preconfigured by the network for the specific terminal device and the first measurement information is broadcasted by the network to the plurality of terminal devices, the third measurement information is considered to be more suitable for the specific terminal device than the first measurement information, and the success rate of requesting or activating the measurement information can be improved, thereby improving the positioning measurement performance.
It should be noted that the execution of S501 and S502 are independent of each other, that is, the execution order of S501 and S502 is not limited, for example, S501 may be executed before S502 or may be executed after S502. And S502 is not a step that must be performed, and is therefore illustrated in fig. 5 with a broken line.
S503, the terminal equipment sends a request message to the network equipment, and correspondingly, the network equipment receives the request message from the terminal equipment.
When the terminal device needs to perform positioning measurement, the terminal device can request the network device to acquire measurement information of the positioning reference signal. For example, the terminal device may send a request message to the network device, which may indicate that measurement information of the positioning reference signal is requested. If the network device is configured with the first measurement information, the terminal device may send a request message to the network device, which may be used to request at least one set of measurement information of the first measurement information. Since the first measurement information is preconfigured, it can also be considered that the request message can be used to request activation of at least one set of measurement information in the first measurement information. If the second indication information indicates that the request for the second measurement information is allowed, or indicates that the request for the second measurement information is made. The terminal device may also request at least one set of measurement information from the network device. I.e. the request message may request at least one set of measurement information of the second measurement information. The request message may also request to activate at least one set of measurement information in the first measurement information or at least one set of measurement information in the second measurement information if the network device is configured with the first measurement information while the second indication information indicates permission to request the second measurement information. The specific measurement information requested by the terminal equipment can be determined according to actual requirements, so that the terminal equipment is more flexible.
Optionally, the request message may include one or more items of information associated with the measurement information to indicate the measurement information to be requested or activated or deactivated. For example, the request message includes one or more items of information such as an ID, area information, priority information, or frequency point information associated with the measurement information. Any of the above information associated with different sets of measurement information may be the same or different. The request message may indicate to the terminal device, via one or more of the above-mentioned items of information associated with the measurement information, that the network device desires to activate or configure the corresponding measurement information.
For example, the request message is used to request activation of at least one set of measurement information in the first measurement information, and the request message may include one or more of ID, area information, priority information, or frequency point information associated with the at least one set of measurement information.
For another example, the request message is used to request measurement information that does not belong to the first measurement information, such as the second measurement information. The request message may include one or more of area information, priority information, or frequency point information associated with the second measurement information. For example, the frequency point information associated with the first measurement information is single frequency point information, and the terminal device may request measurement information other than the single frequency point, that is, the frequency point information included in the request message may be measurement information other than the single frequency point. When the first measurement information includes only configuration information of the PPW, the terminal device may request configuration information of the MG, and the request message may include area information, priority information, or frequency point information associated with the configuration information of the MG. Optionally, the request message may further include fourth indication information, by which the request for measurement information not belonging to the first measurement information is indicated. The network device can know whether the measurement information requested by the terminal device is within the first measurement information range according to the fourth indication information, so that the measurement information requested by the terminal device can be reasonably fed back.
It should be noted that, although the preconfigured first measurement information includes measurement configuration priority information, the priority of measurement configuration of the plurality of sets of positioning reference signals may be indicated, so as to provide a reference for the terminal device to request the measurement information. The terminal device may request measurement information not according to the priority indicated by the measurement configuration priority information. For example, the measurement configuration priority information indicates that the priority of measurement information 1 is higher than the priority of measurement information 2. The terminal device may request measurement information 2, i.e. the request message comprises an ID of 2. That is, the priority of the sets of measurement information indicated by the priority information included in the request message may be the same as or different from the priority configured by the network device for the sets of measurement information. The priority of the terminal device request may be different from the priority of the network device for a certain set of measurement information.
Alternatively, the request message may be MAC CE signaling, or RRC signaling. For example, the request message is used to request to activate at least one set of measurement information in the first measurement information, and the request message may be carried by MAC CE signaling to minimize a time delay for acquiring the measurement information. For another example, the request message is used to request at least one set of measurement information in the second measurement information, and the request message may be carried through RRC signaling, so that more information may be carried to more accurately indicate the measurement information to be requested.
If the network device is configured with both the first measurement information and the third measurement information. For example, the access network device broadcasts the first measurement information via a broadcast message, and the access network device transmits the third measurement information via a unicast message. Of course, the positioning management device may also send the third measurement information via unicast messages. For example, the location management device may request preconfigured measurement information of the location reference signal from the access network device. The access network device responds to the request of the positioning management device and sends the pre-configuration measurement information of the positioning reference signal to the positioning management device. After the positioning management device acquires the preconfigured measurement information of the positioning reference signal, one or more sets of measurement information in the acquired preconfigured information can be sent to the terminal device. Thus, for the terminal device, one or more of the following measurement information may be received: the access network device sends first measurement information based on the broadcast message, the access network device sends third measurement information based on the unicast message, and the positioning management device sends third measurement information based on the unicast message. In this case, the terminal device may request or use more appropriate measurement information from the network according to the need.
Alternatively, the terminal device may determine whether to transmit the request message in a pre-configured or configured priority order. For example, one possible priority order is: the priority of the third measurement information sent by the access network equipment based on the unicast message is higher than the first measurement information sent by the access network equipment based on the broadcast message, the priority of the first measurement information sent by the access network equipment based on the SIB broadcast message is higher than the first measurement information sent by the access network equipment based on the posSIB broadcast message, and the first measurement information sent by the access network equipment based on the broadcast message is higher than the third measurement information sent by the positioning management equipment based on the unicast message. That is, in the case where the network device is preconfigured with the first measurement information based on the broadcast message and the network device also transmits the third measurement information based on the unicast message, the terminal device may preferentially use the third measurement information without requesting the network device to activate at least one set of measurement information in the first measurement information and without requesting the second measurement information. Therefore, S503 is not a step that has to be performed, and is illustrated with a broken line in fig. 5. The following is a specific example.
Example 1, the terminal device receives only the third measurement information. For example, when the terminal device receives the third measurement information sent by the access network device based on the unicast message, the terminal device can perform positioning measurement according to the third measurement information, and does not need to send a request message. Because the third measurement information is specific to the specific terminal equipment, the terminal equipment performs positioning measurement based on the third measurement information, and better positioning performance can be obtained.
Example 2, the terminal device receives only the first measurement information. For example, when the terminal device receives the first measurement information sent by the access network device based on the broadcast message, and does not receive the third measurement information sent by the access network device based on the unicast message, the terminal device may send a request message to the access network device or the positioning management device to request to activate at least one set of measurement information in the first measurement information, so as to perform positioning measurement based on the at least one set of measurement information.
For example, the terminal device may only receive the first measurement information sent by the access network device based on the SIB broadcast message, and the terminal device may send a request message to the access network device or the positioning management device to request activation of at least one set of measurement information in the first measurement information. The terminal device only receives the first measurement information sent by the access network device based on the posSIB broadcast message, and the terminal device can send a request message to the access network device or the positioning management device to request to activate at least one set of measurement information in the first measurement information. The terminal device receives the first measurement information sent by the access network device based on the SIB broadcast message, and the terminal device receives the first measurement information sent by the access network device based on the posSIB broadcast message, and the terminal device may send a request message to the access network device or the positioning management device to request to activate at least one set of measurement information in the first measurement information sent based on the SIB broadcast message.
Example 3, the terminal device receives the first measurement information and the third measurement information. For example, the terminal device receives the first measurement information sent by the access network device based on the broadcast message, and receives the third measurement information sent by the access network device based on the unicast message, and the terminal device may perform positioning measurement according to the third measurement information, without sending the request message. For another example, the terminal device may also send a request message to the access network device or the positioning management device to request to activate at least one set of measurement information in the first measurement information, so as to perform positioning measurement based on the at least one set of measurement information, when the terminal device receives the first measurement information sent by the access network device based on the broadcast message and receives the third measurement information sent by the positioning management device based on the unicast message.
For the terminal device in the non-connection state, when the first indication information indicates that the P-set measurement information in the first measurement information is used for the terminal device in the non-connection state, or the first indication information indicates that the terminal device in the non-connection state is allowed to request the P-set measurement information in the first measurement information. Wherein P is an integer greater than or equal to 1. The terminal device in the non-connected state may request at least one set of measurement information among the P sets of measurement information. For example, a terminal device in a non-connected state may transmit a request message, which may request activation of at least one of the P sets of measurement information. The request message may also be considered to be sent by a terminal device in a non-connected state. The terminal equipment in the non-connection state can request to acquire the measurement information without entering the connection state, so that the positioning process can be simplified. And the communication flow which needs to be executed by the terminal equipment is reduced, so that the energy consumption of the terminal equipment can be reduced, the terminal equipment can be positioned with lower power consumption, and the service life of the terminal equipment is prolonged.
Optionally, the request message is message 1 in the random access procedure, or the request message is message a in the random access procedure. Alternatively, the request message may be a preconfigured grant request message, i.e. the terminal device initiates the request by a preconfigured grant.
If the network device configures the first measurement information, and the third indication information included in the first measurement information indicates that the terminal device can request to activate or deactivate the measurement configuration information of the positioning reference signal. The terminal device in the non-connected state may consider that it may request to activate or deactivate measurement configuration information of the positioning reference signal according to the third indication information. In this case, the terminal device in the non-connected state may transmit the request message in the EDT or PUR or SDT process. That is, the terminal device can send the request message in EDT, PUR or SDT mode, and can acquire the measurement information of the positioning reference signal without the terminal device entering the connected state, thereby reducing the signaling interacted by the terminal device and saving the energy consumption of the terminal device.
S504, the network equipment sends a response message to the terminal equipment, and correspondingly, the terminal equipment receives the response message from the network equipment.
The network device receives the request message of the terminal device, and can send a response message to the terminal device in response to the request of the terminal device. For example, the request message is for requesting activation of at least one set of measurement information in the first measurement information, and the response message may also include at least one set of measurement information in the first measurement information. For another example, a request message is used to request activation of at least one set of measurement information in the first measurement information, and the response message may indicate the at least one set of measurement information that has been activated. For example, the response message includes indication information corresponding to the at least one set of measurement information respectively to indicate activation, thereby saving transmission overhead. Alternatively, the response message may indicate that the at least one set of measurement information in the first measurement information is not activated, or the response message may indicate that a part of measurement information in the at least one set of measurement information is not activated. Similarly, the request message is for requesting at least one set of measurement information in the second measurement information, and the response message may include or indicate the at least one set of measurement information in the second measurement information. It will be appreciated that if the request message requests activation of at least one set of measurement information in the first measurement information and requests at least one set of measurement information in the second measurement information, the response message may include at least one set of measurement information in the first measurement information and at least one set of measurement information in the second measurement information. Alternatively, the response message may indicate that at least one set of measurement information in the first measurement information is activated and at least one set of measurement information in the second measurement information is included.
Optionally, the request message is message 1 in the random access procedure, and the response message is message 4 in the random access procedure. Or the request message is a message A in the random access process, and the response message is a message B in the random access process. Or the request message is a pre-configuration authorization request message, and the response message is a pre-configuration authorization response message. That is, the terminal device initiates a request through a pre-configured grant (pre-configured grant), and the network device responds with a pre-configured grant indicating measurement information.
S505, the terminal equipment performs positioning measurement according to the first information and/or the second information.
The terminal device performs positioning measurement, or it may be considered that the terminal device performs positioning based on the positioning reference signal, or the terminal device performs measurement based on measurement information of the positioning reference signal. For example, some characteristic parameters of the positioning reference signal are measured. For example, reference signal received power (reference signal receiving power, RSRP) of the positioning reference signal is measured, so that the terminal device is positioned according to the measurement result of RSRP.
In one possible implementation, the terminal device receives the first measurement information sent by the network device based on the broadcast message, and does not immediately perform the positioning measurement. For example, the terminal device may perform the positioning measurement based on at least one set of measurement information after the network device activates the at least one set of measurement information in the first measurement information. The priority of the third measurement information sent by the access network device based on the unicast message is higher than the first measurement information sent by the access network device based on the broadcast message, the priority of the first measurement information sent by the access network device based on the SIB broadcast message is higher than the first measurement information sent by the access network device based on the posSIB broadcast message, and the first measurement information sent by the access network device based on the broadcast message is higher than the third measurement information sent by the positioning management device based on the unicast message. Therefore, the terminal device may perform the positioning measurement based on the first measurement information and/or the third measurement information according to the priority order, and reference may be specifically made to the content related to the foregoing examples 1 to 3, which is not described herein.
In the embodiment of the application, the measurement information of the positioning reference signal is sent in a broadcast mode, so that the network equipment can simultaneously pre-configure the measurement information of the positioning reference signal for a plurality of terminal equipment. Compared with the network equipment which respectively and independently pre-configures the measurement information of the positioning reference signals for each terminal equipment, the signaling overhead for configuring the measurement information of the positioning reference signals can be reduced. In addition, the measurement information of the positioning reference signal can be carried in the system information, and the measurement information of the positioning reference signal can be obtained without the terminal equipment completing random access, so that the positioning of the terminal equipment in a non-connection state can be realized. And the communication processes such as random access and the like which are needed to be executed before the terminal equipment is positioned are reduced, so that the positioning process is simplified, and the power consumption of the terminal equipment is saved. In addition, since a communication flow such as random access is not required, positioning of terminal devices in some scenarios is facilitated. For example to facilitate the positioning of the terminal device in a scenario such as EDT, PUR, SDT.
In the embodiments of the present application described above, the method provided in the embodiments of the present application is described from the perspective of interaction among the terminal device, the network device, and the location management device. The steps performed by the network device may also be implemented by different communication apparatuses. For example: the first device is configured to generate a broadcast message, and the second device is configured to send the broadcast message, that is, the first device and the second device together complete the steps executed by the network device in the embodiment of the present application, which is not limited to a specific division manner. When one or more Distributed Units (DUs), one or more Centralized Units (CUs) and one or more radio frequency units (RUs) are included in the network architecture, the steps performed by the above network devices may be implemented by the DUs, CUs and RUs, respectively. In order to implement the functions in the method provided by the embodiment of the present application, the terminal device and the network device may include hardware structures and/or software modules, and implement the functions in the form of hardware structures, software modules, or a combination of hardware structures and software modules. Some of the functions described above are performed in a hardware configuration, a software module, or a combination of hardware and software modules, depending on the specific application of the solution and design constraints.
Communication devices for implementing the above method in the embodiments of the present application are described below with reference to the accompanying drawings.
As shown in fig. 6, which is a possible exemplary block diagram of a communication apparatus according to the present application, the communication apparatus 600 may correspondingly implement the functions or steps implemented by the terminal device or the network device in the above-described respective method embodiments. The communication device may comprise a transceiver module 601 and a processing module 602. Optionally, a storage module may be included, which may be used to store instructions (code or programs) and/or data. The transceiver module 601 and the processing module 602 may be coupled to the memory module, for example, the processing module 602 may read instructions (code or program) and/or data in the memory module to implement a corresponding method. The above modules may be independently provided, or may be partially or fully integrated.
It is to be appreciated that the processing module 602 may be a processor or controller, such as a general purpose central processing unit (central processing unit, CPU), general purpose processor, digital signal processing (digital signal processing, DSP), application specific integrated circuit (application specific integrated circuits, ASIC), field programmable gate array (field programmable gate array, FPGA) or other programmable logic device, transistor logic device, hardware components, or any combination thereof. Which may implement or perform the various exemplary logic blocks, modules and circuits described in connection with this disclosure. The processor may also be a combination that performs the function of a computation, e.g., including one or more microprocessors, a combination of a DSP and a microprocessor, and so forth. The transceiver module 601 is an interface circuit of the device for receiving signals from other devices. For example, when the device is implemented as a chip, the transceiver module 601 is an interface circuit of the chip for receiving signals from other chips or devices, or an interface circuit of the chip for transmitting signals to other chips or devices.
The communication apparatus 600 may be a network device or a terminal device in the above embodiment, or may be a chip for implementing the functions of the network device or the terminal device in the above embodiment. When the communication apparatus 600 is a network device or a terminal device, the processing module 602 may be, for example, a processor, and the transceiver module 601 may be, for example, a transceiver. Alternatively, the transceiver may comprise radio frequency circuitry and the storage unit may be, for example, a memory. For example, when the communication apparatus 600 is a chip for implementing functions of a network device or a terminal device, the processing module 602 may be, for example, a processor, and the transceiver module 601 may be, for example, an input/output interface, a pin, a circuit, or the like. The processing module 602 may execute computer-executable instructions stored in a memory unit, optionally, a memory unit in the chip, such as a register, a cache, etc., and the memory unit may also be a memory unit in the network device, the terminal device, or the location management device, which is located outside the chip, such as a read-only memory (ROM) or other type of static storage device, a random access memory (random access memory, RAM), etc., where static information and instructions may be stored.
In some possible embodiments, the communications apparatus 600 can correspondingly implement the behaviors and functions of the terminal device in the above method embodiments. For example, the communication apparatus 600 may be a terminal device, or may be a component (e.g., a chip or a circuit) applied to the terminal device. The transceiver module 601 may be used to support communication between a terminal device and other network entities, such as between a terminal device and a network device and/or a location management device as shown in fig. 5. The processing module 602 is configured to control and manage actions of the terminal device, for example, the processing module 602 is configured to support the terminal device to perform all operations of the terminal device except for transceiving in fig. 5.
For example, the transceiver module 601 may be configured to perform all of the receiving or transmitting operations performed by the terminal device in the embodiment shown in fig. 5, such as S501, S502, S503, S504, etc. in the embodiment shown in fig. 5, and/or other processes for supporting the techniques described herein. Wherein the processing module 602 is configured to perform all operations performed by the terminal device, except for the transceiving operations in the embodiment shown in fig. 5, such as S505 in the embodiment shown in fig. 5, and/or other procedures for supporting the techniques described herein.
