In the first aspect and its possible implementation manner, the communication method is described as an example executed by the terminal device. In the method, a terminal device acquires first priority information for indicating priorities of at least two auxiliary data information (AD), wherein the auxiliary data information includes downlink reference signal configuration information; the terminal equipment measures downlink reference signals based on the first priority information and the at least two auxiliary data information to obtain a measurement result; the terminal device transmits the measurement result.

In other words, the terminal device measures the downlink reference signal based on the auxiliary data information determined by the acquired indication of the first priority information, and obtains and transmits a measurement result, so that the network device locates the terminal device based on the measurement result. Therefore, under the condition that at least two pieces of auxiliary data information exist, the terminal equipment can conduct measurement by using the better auxiliary data information preferentially based on the first priority information, the situation that the terminal equipment uses the worse auxiliary data information to conduct measurement is avoided, and efficient positioning measurement is achieved.

In a possible implementation manner of the first aspect, the obtaining, by the terminal device, the first priority information may include: the terminal device receives first priority information.

Specifically, "alignment" refers to the coincidence of the two understandings of the carrier frequency of the interactive messaging, the determination of the type of interactive message, the meaning of field information carried in the interactive message, or other configuration of the interactive message, when there is an interactive message between the network device and the terminal device.

Furthermore, the network device may be other means of providing wireless communication functionality for the terminal device, as other possibilities.

The embodiments of the present application described below do not limit the scope of the present application.

In order to facilitate understanding of the method provided by the embodiments of the present application, a system architecture of the method provided by the embodiments of the present application will be described below. It can be understood that the system architecture described in the embodiments of the present application is for more clearly describing the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application.

Fig. 1 is a schematic diagram of a communication system according to an embodiment of the present application. Referring to fig. 1, the communication system includes a terminal device 100 and network access network device 201 and core network device 202. The terminal device 100 and the access network device 201 may communicate via a wireless link. Communication may be performed between the access network device 201 and the core network device 202.

As an example of implementation, the communication system between the terminal device and the access network device may be implemented in the manner shown in fig. 2 a. Referring to fig. 2a, the communication system includes a terminal device 101, and an access network device may include a next generation node B (next Generation Node B, gNB) 102, a next generation evolved node B (next generation evolved Node B, ng-eNB) 103, or other access network device, as shown. Wherein the terminal device 101 communicates with an access network device (e.g., the gNB102 or the ng-eNB103 in fig. 1) via a Uu interface. The ng-eNB103 is an access network device in a long term evolution (Long Term Evolution, LTE) communication system, and the gNB102 is an access network device in an NR communication system.

As an example of implementation, the communication system between the access network device and the core network device may be implemented in the manner shown in fig. 2 b. Referring to fig. 2b, the communication system comprises an access network device, which may comprise, for example, a gNB102 and a ng-eNB103 as shown, and a core network device, which may comprise an access and mobility management function (access and mobility management function, AMF) 104 and a location management function (location management function, LMF) 105 as shown. The LMF105 is a network element, module or component in the NR core network that provides a positioning function for a terminal device.

In the communication system, the access network devices may communicate through an Xn interface, and the access network devices may communicate with the AMF104 through an NG-C interface. Communication between the AMF104 and the LMF105 may be performed through the NL1 interface, and the AMF104 corresponds to a router for communication between the access network device and the LMF 105. The LMF105 is used to perform positioning calculations for the location of the terminal device.

Fig. 2a above only shows an example of two access network devices of a communication system comprising a gNB and a ng-eNB. In practical applications, the communication system may include at least one access network device, which is not limited in this application.

In the present application, in the communication system shown in fig. 2b, the LMF is the name in the current communication system, and in future communication systems, the name of the LMF may change with the evolution of the communication system. In the present communication system or the future communication system, the LMF in the embodiments of the present application can be understood as long as the functional network element having other names with functions similar to those of the LMF is provided, and is applicable to the communication method provided in the embodiments of the present application.

In the communication systems shown in fig. 1, 2a and 2b, the access network and terminal assisted architecture may be used to implement the positioning procedure of the terminal device based on core network positioning management function (Location management function, LMF) control. In general, the downlink positioning method mainly uses observed time difference of arrival (observed time difference of arrival, OTDOA), and determines the position of the terminal device by measuring the time of arrival of downlink reference signals of a plurality of cells at the terminal device and the time difference of arrival (time difference of arrival, TDOA) of downlink signals of a base station of the reference cell at the terminal device. Illustratively, NR defines other downlink positioning techniques such as those based on angle of departure (angle of departure, aoD). In this technique, the AoD of each base station is inferred and calculated from measurement information obtained by the terminal device measuring downlink reference signals of a plurality of base stations, and the position of the terminal device is determined based on the aods of the plurality of base stations.

In this application, the UE may have three RRC states: an RRC CONNECTED state (RRC CONNECTED), an RRC inactive state (RRC INACTIVE), and an RRC IDLE state (RRC IDLE).

Rrc connected state: the UE is connected with the base station through RRC, and the connection between the base station and the core network is established for the UE; the base station stores the context of the UE; in the connected state the base station and the UE can send unicast messages over the RRC connection.

Rrc inactive state: the RRC connection between the UE and the base station is suspended (suspend), and the connection between the base station and the core network is established for the UE; the base station stores the context of the UE and knows the base station notification area to which the UE belongs; the UE may receive a broadcast message and a paging message of the base station, wherein the paging message is initiated by the base station.

Rrc idle state: no RRC connection is established between the UE and the base station, and no connection between the base station and the core network is established for the UE. The base station has no context of the UE; the UE may receive a broadcast message and a paging message, wherein the paging message is initiated by the core network.

As an implementation example of a positioning procedure, as shown in fig. 3, when a UE communicates with a plurality of access network devices (including the access network device 1, the access network device 2, and the access network device 3, etc.), a hyperbolic curve (OTDOA hyper bola) positioning area may be determined between each two access network devices, including: the UE-to-access network device 1 and the UE-to-access network device 2 differ by a distance d0-d1 forming one hyperbola and the UE-to-access network device 1 and the UE-to-access network device 3 differ by a distance d0-d2 forming another hyperbola. Therefore, an intersection point can be determined through the two hyperbolas, and the exact position of the UE can be obtained by applying additional conditions (such as the self geographic position information of the access network equipment), so that the positioning of the UE is realized.

Therefore, the application provides a communication method and a communication device, so that efficient positioning measurement is expected to be realized. The solution provided in the present application will be described by a plurality of examples.

Referring to fig. 4, a schematic diagram of a communication method provided in the present application includes the following steps.

S401, the terminal equipment acquires first priority information. Wherein the first priority information is used for indicating the priority of at least two pieces of auxiliary data information (AD), and the auxiliary data information comprises downlink reference signal configuration information.

As an implementation manner for the terminal device to acquire the first priority information, in step S401, the network device sends the first priority information to the terminal device. In other words, the network device transmits the first priority information to the terminal device in step S401, and the terminal device receives the first priority information from the network device in step S401, accordingly. Therefore, the network equipment can clearly determine the auxiliary data information corresponding to the measurement result reported by the terminal equipment.

It should be noted that, the network devices mentioned in this embodiment and the following embodiments may include an LMF.

In one possible implementation, in step S401, the first priority information is carried in a request positioning information message or a provide assistance data message. Specifically, the first priority information may be carried in a positioning request information message for requesting positioning or an auxiliary data providing message for carrying auxiliary data information, so as to save signaling consumption and improve communication efficiency.

In one possible implementation, the auxiliary data information included in the at least two pieces of auxiliary data information may have a plurality of implementations. For example, the assistance data information may be carried in a positioning system message block (position system information block, posSIB); as another example, the assistance data information may be carried in a long term evolution positioning protocol (long term evolution positioning protocol, LPP) message.

In one possible implementation, the terminal device may determine that the terminal device preferentially uses part of the at least two auxiliary data information in other ways than acquiring the first priority information based on the manner indicated by the network device in step S401.

Alternatively, the auxiliary data information may be sent by the network device to the terminal device, and the terminal device may acquire the first priority information based on the receiving moments of at least two auxiliary data information.

For example, the earlier the reception time, the lower the priority of the auxiliary data information, whereas the later the reception time, the higher the priority of the auxiliary data information. For another example, the higher the difference between the reception time and the current time, the lower the priority of the auxiliary data information, whereas the lower the difference between the reception time and the current time, the higher the priority of the auxiliary data information.

In other words, the terminal device determines the time to acquire the at least two pieces of auxiliary data information, and uses the latest received auxiliary data information preferentially. Therefore, the terminal equipment performs downlink reference signal measurement based on the auxiliary data information recently indicated by the network equipment, so that the network equipment can clearly determine the auxiliary data information corresponding to the measurement result subsequently reported by the terminal equipment, and the accuracy of positioning can be improved.

Alternatively, the terminal device may preferentially use the assistance data information carried in the LPP message. Because the LPP message is a unicast message sent by the network device to the terminal device, the terminal device executes a subsequent downlink reference signal measurement process based on the auxiliary data information contained in the unicast message, so that the network device can clearly determine that the measurement result subsequently reported by the terminal device is the auxiliary data information corresponding to the unicast message, which is beneficial to the network device to execute positioning for different terminal devices based on different unicast messages, and the positioning accuracy is improved.

Optionally, the terminal device may receive at least two assistance data information, and may include one or more assistance data information carried in a PosSIB, and one or more assistance data information carried in an LPP message. For example, the at least two assistance data information may include assistance data information carried in the PosSIB received last time and assistance data information carried in the LPP message received last time.

In the following, a procedure in which the terminal device obtains the assistance data information carried in the PosSIB is exemplified by way of example in fig. 5 a. As shown in fig. 5a, the terminal device is taken as UE, and the network device includes NG-RAN Node (Node) and LMF for example. Wherein the LMF first sends a new radio positioning protocol a assistance information control (NRPPa Assistance Information Control) message to the NG-RAN Node, the NRPPa Assistance Information Control message may include assistance data information. In addition, after receiving the auxiliary data sent by the LMF, the NG-RAN Node sends radio resource control system information (RRC System Information) including the PosSIB to the UE. The process of NG-RAN Node sending RRC System Information to UE includes: the NG-RAN Node generates a PosSIB carrying auxiliary data information, and then broadcasts RRC System Information containing the PosSIB in a broadcast channel, so that the terminal device receives the auxiliary data information carried in the PosSIB.

Illustratively, a procedure in which the terminal device obtains the assistance data information carried in the LPP message is described below as an example in fig. 5 b. As shown in fig. 5b, the terminal device is taken as a UE, and the network device includes an LMF as an example. The LMF sends an LPP message carrying the assistance data information to the UE, for example, the LPP message may be a Provide Assistance Data message in the illustration. Alternatively, the LMF may be forwarded through other network devices (e.g., AMF, access network device, etc.) such that the UE receives the LPP message.

S402, the terminal equipment measures the downlink reference signal based on the first priority information and at least two pieces of auxiliary data information to obtain a measurement result.

In this embodiment, after the terminal device obtains the first priority information in step S401, the terminal device measures the downlink reference signal based on the first priority information and at least two pieces of auxiliary data information in step S402, so as to obtain a measurement result.

In one implementation, the terminal device may measure the downlink reference signal using one or more of the at least two assistance data information based on the first priority information in step S402, to obtain a measurement result. For example, in an implementation in which the terminal device performs measurement using a plurality of the at least two pieces of auxiliary data information, the terminal device may sequentially perform measurement on the plurality of pieces of auxiliary data information based on the priority indicated by the first priority information. As another example, in an implementation in which the terminal device uses a certain assistance data information of the at least two assistance data information for measurement, the terminal device may measure the assistance data information based on the priority indicated by the first priority information.

S403, the terminal equipment sends the measurement result to the network equipment.

In this embodiment, after the terminal device obtains the measurement result in step S402, the terminal device sends the measurement result to the network device in step S403. Accordingly, the network device receives the measurement result from the terminal device in step S403.

It should be noted that, in the embodiment of the present application, the downlink reference signals may include positioning reference signals (positioning reference signal, PRS), or other downlink reference signals used for positioning, for example, channel state information reference signals (channel state information reference signal, CSI-RS), tracking reference signals (tracking reference signal, TRS), and the like, which are not limited herein. Further, the measurement result may include at least one of reference signal received power (reference signal received power, RSRP), reference signal received quality (reference signal received quality, RSRQ), reference signal time difference (reference signal time difference), and received transmit time difference (Rx-Tx time difference).

Based on the technical solution shown in fig. 4, after the terminal device obtains the first priority information for indicating the priority of the at least two pieces of auxiliary data information in step S401, the measurement result sent by the terminal device in step S403 is a measurement result measured based on the first priority information and the at least two pieces of auxiliary data information. In other words, the terminal device measures the downlink reference signal based on the auxiliary data information determined by the acquired indication of the first priority information, and obtains and transmits a measurement result, so that the network device locates the terminal device based on the measurement result. Therefore, under the condition that at least two pieces of auxiliary data information exist, the terminal equipment can conduct measurement by using the better auxiliary data information preferentially based on the first priority information, the situation that the terminal equipment uses the worse auxiliary data information to conduct measurement is avoided, and efficient positioning measurement is achieved.

The communication method provided in the present application (i.e. the implementation manner in which the terminal device performs measurement using one of the at least two auxiliary data information in step S402) will be further described by the implementation procedure shown in fig. 6.

Referring to fig. 6, another schematic diagram of a communication method provided in the present application includes the following steps.

S601, the terminal equipment acquires first priority information.

S602, the terminal equipment determines first auxiliary data information in at least two auxiliary data information based on the first priority information.

S603, the terminal equipment measures the downlink reference signal based on the first auxiliary data information to obtain a measurement result.

S604, the terminal equipment sends a measurement result to the network equipment.

Note that, in the implementation process shown in fig. 6, the implementation process of step S601 may refer to the implementation process of step S401 shown in fig. 4, and the implementation process of step S604 may refer to the implementation process of step S403 shown in fig. 4. Whereas step S402 shown in fig. 4 can be implemented by step S602 and step S603 shown in fig. 6. In other words, the process of measuring the downlink reference signal by the terminal device based on the first priority information and the at least two pieces of auxiliary data information in step S402 to obtain a measurement result may include: s602, the terminal equipment determines first auxiliary data information in the at least two auxiliary data information based on the first priority information; s603, the terminal equipment measures the downlink reference signal based on the first auxiliary data information to obtain the measurement result.

Based on the technical solution shown in fig. 6, the terminal device may first determine first auxiliary data information in the at least two auxiliary data information based on the first priority information; and the terminal equipment measures the downlink reference signal based on the first auxiliary data information to obtain the measurement result.

In one possible implementation manner, the first auxiliary data information determined by the terminal device in step S602 is the auxiliary data information with the highest priority among the at least two auxiliary data information indicated by the first priority information. Specifically, the first auxiliary data information is the auxiliary data information with the highest priority among the at least two auxiliary data information indicated by the first priority information, wherein the measurement result sent by the terminal device is the measurement result corresponding to the first auxiliary data information. In other words, the terminal device may not need to perform measurement based on the assistance data information of the other priority than the highest priority among the at least two assistance data information indicated by the first priority information. Thus, the terminal device enables the terminal device to reduce power consumption in a communication scenario comprising at least two auxiliary data information.

In the implementation process shown in fig. 6, in step S603, the terminal device measures the downlink reference signal based on the first auxiliary data information, to obtain a measurement result. The downlink reference signal configuration information included in the first auxiliary data information may include one or more downlink reference signal resource information. For example, when the downlink reference signal resource information is one, the terminal device may perform measurement based on the one downlink reference signal resource information to obtain a measurement result in step S603. As another example, when the downlink reference signal resource is plural, the terminal device may perform measurement based on the plural downlink reference signal resource information to obtain a measurement result in step S603. The implementation procedure of the latter (i.e., the terminal device may perform measurement based on the plurality of downlink reference signal resource information to obtain a measurement result in step S603) will be described by the implementation shown in fig. 7.

Referring to fig. 7, another schematic diagram of a communication method provided in the present application includes the following steps.

S701, the network equipment sends first priority information to the terminal equipment.

S702, the terminal equipment determines first auxiliary data information in at least two auxiliary data information based on the first priority information.

S703, the network equipment sends second priority information to the terminal equipment. The second priority information is used for indicating the priority of first information, the first information is associated with at least two pieces of downlink reference signal resource information configured by downlink reference signal configuration information contained in the first auxiliary data information, and the first information comprises at least one of the following items: and transmitting the TRP information of the receiving point by using the frequency layer information, and downlink reference signal index or downlink reference signal resource set index.

S704, the terminal equipment measures the downlink reference signal based on the second priority information and the first auxiliary data information to obtain a measurement result.

And S705, the terminal equipment sends the measurement result to the network equipment.

It should be noted that, the first priority information received by the terminal device in step S701 and the second priority information received by the terminal device in step S703 may be carried in the same message or may be carried in different messages.

Alternatively, when the first priority information and the second priority information are carried in different messages, the network device may perform step S701 to send the first priority information before performing step S703 to send the second priority information, or may perform step S703 to send the second priority information before performing step S701 to send the first priority information, which is not limited herein.

In the implementation process shown in fig. 7, the implementation process of step S701 and step S702 may refer to the implementation process of step S601 and step S602 shown in fig. 6, and the implementation process of step S705 may refer to the implementation process of step S604 shown in fig. 6. And step S603 shown in fig. 6 can be implemented by step S703 and step S704 shown in fig. 7. In other words, in step S603, the process of measuring the downlink reference signal by the terminal device based on the first auxiliary data information to obtain a measurement result specifically includes: s703, the terminal equipment receives second priority information from the network equipment; s704, the terminal equipment measures a downlink reference signal based on the second priority information and the first auxiliary data information to obtain a measurement result; the downlink reference signal configuration information included in the first auxiliary data information includes at least two downlink reference signal resource information, the second priority information is used for indicating a priority of first information, the first information is associated with the downlink reference signal resource information, and the first information includes at least one of the following: and transmitting the TRP information of the receiving point by using the frequency layer information, and downlink reference signal index or downlink reference signal resource set index.

Based on the technical solution shown in fig. 7, the measurement result sent by the terminal device is a measurement result corresponding to first auxiliary data information, where downlink reference signal configuration information included in the first auxiliary data information includes at least two downlink reference signal resource information, where the first information may be associated with the downlink reference signal resource information, so that the terminal device determines the measurement result based on second priority information used to indicate the first information. Therefore, in a communication scene that the auxiliary data information used by the terminal equipment comprises at least two downlink reference signal resource information, the terminal equipment can preferentially use the better downlink reference signal resource information to measure based on the second priority information, so that the terminal equipment is prevented from using the worse downlink reference signal resource information to measure, and efficient positioning measurement is realized. Furthermore, the terminal equipment can measure the downlink reference signal based on the indication (namely the second priority information) of the network equipment to obtain and report a measurement result, so that the accuracy of the network equipment for positioning the terminal equipment based on the measurement result is further improved.

In a possible implementation manner, the process of measuring, by the terminal device, the downlink reference signal based on the second priority information and the first auxiliary data information in step S704, to obtain the measurement result may include: and the terminal equipment sequentially measures the downlink reference signals corresponding to the at least two downlink reference signal resource information based on the second priority information to obtain the measurement result. The terminal device can sequentially measure downlink reference signals corresponding to at least two downlink reference signal resource information associated with the first information based on the priority of the first information indicated by the second priority information, so as to obtain a measurement result, and realize efficient positioning measurement.

In one possible implementation, the second priority information is carried in a request for positioning information (request location information) message or a provide assistance data (provide location information) message. Specifically, the second priority information may be carried in a positioning request information message for requesting positioning or an auxiliary data providing message for carrying auxiliary data information, so as to save signaling consumption and improve communication efficiency.

Optionally, the second priority information includes at least one of:

The priority of the first information takes a value.

Alternatively, the index order of the first information is the index order of the first information carried by the first cell, and the first cell may be a new air interface-selected downlink-positioning reference signal-index list (NR-selected DL-PRS-index list) cell, or other cells, for example, a downlink-positioning reference signal-priority list (DL-PRS-priority list) cell, which is not limited herein. For example, the earlier the index order of the first information is, the higher the priority of the downlink reference signal resource information associated with the first information is; conversely, the later the index order of the first information, the lower the priority of the downlink reference signal resource information associated with the first information. For another example, the later the index order of the first information is, the higher the priority of the downlink reference signal resource information associated with the first information is; conversely, the earlier the index order of the first information is, the lower the priority of the downlink reference signal resource information associated with the first information is. Optionally, the priority value of the first information is positively correlated with the priority level of the downlink reference signal resource information associated with the first information. That is, the higher the priority value of the first information is, the higher the priority of the downlink reference signal resource information associated with the first information is; conversely, the smaller the priority value of the first information is, the lower the priority of the downlink reference signal resource information associated with the first information is.

In a possible implementation manner, the terminal device measures the downlink reference signal in step S402 (or in step S603 or step S704), and before obtaining the measurement result, the method further includes: the terminal equipment receives indication information, wherein the indication information is used for indicating that auxiliary data information is reserved when the terminal equipment enters an Inactive state (Idle) and/or an Idle state; the process of the terminal device measuring the downlink reference signal in step S402 (or in step S603 or step S704) to obtain a measurement result may include: the terminal device measures the downlink reference signal based on the indication information in step S402 (or in step S603 or step S704) to obtain a measurement result. Specifically, when the terminal device enters the inactive state and/or the idle state, the terminal device may measure the downlink reference signal based on the indication information and the first auxiliary data information, so as to obtain a measurement result. The indication information is used for indicating that auxiliary data information is reserved when the terminal equipment enters an inactive state and/or an idle state, so that the situation that the terminal equipment cannot measure due to default release of the auxiliary data information when the terminal equipment enters the inactive state and/or the idle state is avoided.

Optionally, the indication information is carried in a provide assistance data message or a radio resource control release (radio resource control release, RRCRelease) message. The indication information is carried in the auxiliary data providing message or the radio resource control release message, so that signaling consumption is saved, and communication efficiency is improved.

Specifically, the terminal device can release the auxiliary data information based on the first indication information, so that the terminal device can timely release the downlink reference signal resource information, thereby releasing the storage resource of the terminal device and reducing the energy consumption waste caused by the loading of the storage information.

In one possible implementation, during any of the methods shown in fig. 4 to 7, the method further includes: the terminal device receives a first message comprising a mobile originated location request (mobile originated location request, MO-LR) response (response) message, a cancel location acknowledgement (cancel location acknowledgement, cancel location ACK) message or a cancel location (cancel location) message; the terminal device measures the downlink reference signal in step S402 (or in step S603 or step S704), and releases the auxiliary data information based on the first message after obtaining the measurement result. Optionally, the terminal device releasing the assistance data information based on the first message includes the terminal device releasing one or more of the at least two assistance data information based on the first message.

Alternatively, the first indication information may be implemented by the first message herein.

Specifically, the terminal device can release the auxiliary data information based on the first message, so that the terminal device can release the auxiliary data information in time, thereby releasing the storage resources of the terminal device and reducing the energy consumption waste caused by the loading of the storage information.

In one possible implementation, during any of the methods shown in fig. 4 to 7, the method further includes: the terminal equipment receives second indication information, wherein the second indication information is used for indicating to release auxiliary data information carried in PosSIB and/or auxiliary data information carried in LPP information; the terminal device measures the downlink reference signal in step S402 (or step S603 or step S704), and releases the assistance data information carried in the PosSIB and/or the assistance data information carried in the LPP message based on the second indication information after obtaining the measurement result. Specifically, the terminal device may release specific auxiliary data information based on the indication (second indication information) of the network device, so that the terminal device may timely release the auxiliary data information carried in the PosSIB and/or the auxiliary data information carried in the LPP message, so as to release storage resources of the terminal device and reduce energy consumption waste caused by loading the storage information.

Alternatively, the first indication information may be implemented by the second indication information.

In one possible implementation, during any of the methods shown in fig. 4 to 7, the method further includes: the terminal equipment receives third indication information, wherein the third indication information is used for indicating to release downlink reference signal resource information corresponding to second information, and the second information comprises at least one of the following items: frequency layer information, transmitting receiving point TRP information, positioning reference signal index or positioning reference signal resource set index; the terminal device measures the downlink reference signal in step S402 (or step S603 or step S704), and releases the downlink reference signal resource information corresponding to the second information based on the third indication information after obtaining the measurement result. Specifically, the terminal device may release specific downlink reference signal configuration information included in the auxiliary data information based on the indication (third indication information) of the network device, so that the terminal device may timely release downlink reference signal resource information corresponding to the second information, so as to release storage resources of the terminal device and reduce energy consumption waste caused by loading of the storage information.

Alternatively, the first indication information may be implemented by the third indication information herein.

In one possible implementation, during any of the methods shown in fig. 4 to 7, the method further includes: the terminal equipment receives fourth indication information, wherein the fourth indication information is used for indicating to reserve or release auxiliary data information; the terminal device measures the downlink reference signal in step S402 (or in step S603 or step S704), and retains or releases the auxiliary data information based on the fourth indication information after obtaining the measurement result. Specifically, the terminal device may reserve the auxiliary data information based on the indication (fourth indication information) of the network device to implement positioning, or the terminal device may release the auxiliary data information based on the indication (fourth indication information) of the network device to release the storage resource of the terminal device and reduce the energy consumption waste caused by loading the storage information, so that the terminal device may explicitly reserve or release the auxiliary data information based on the indication of the network device.

Alternatively, the first indication information may be implemented by the fourth indication information herein.

In various implementations of the foregoing embodiment shown in fig. 4, a part of the implementation process may also be implemented separately from the implementation process shown in fig. 4, and will be described below in connection with a specific embodiment.

Example 1

Referring to fig. 8a, another schematic diagram of a communication method provided in the present application includes the following steps.

S801, the network equipment sends indication information to the terminal equipment.

In this embodiment, the network device sends the indication information to the terminal device in step S801, and the terminal device receives the indication information from the network device in step S801. The indication information is used for indicating that auxiliary data information is reserved when the idle state and/or the inactive state are/is entered, and the auxiliary data information comprises downlink reference signal configuration information.

S802, the terminal equipment measures the downlink reference signal based on the downlink reference signal configuration information to obtain a measurement result.

In this embodiment, the terminal device reserves auxiliary data information when entering the inactive state and/or the idle state, and measures the downlink reference signal based on the downlink reference signal configuration information included in the reserved auxiliary data information in step S802, so as to obtain a measurement result.

S803, the terminal equipment sends the measurement result to the network equipment.

In this embodiment, after the terminal device obtains the measurement result in step S802, the terminal device sends the measurement result to the network device in step S803.

Based on the technical scheme shown in fig. 8a, when the terminal device enters the inactive state and/or the idle state, the terminal device may determine to reserve auxiliary data information based on the indication information, and measure the downlink reference signal based on the downlink reference signal configuration information included in the reserved auxiliary data information, so as to obtain a measurement result. The indication information is used for indicating that auxiliary data information is reserved when the terminal equipment enters an inactive state and/or an idle state, so that the situation that the terminal equipment cannot measure due to default release of the auxiliary data information when the terminal equipment enters the inactive state and/or the idle state is avoided.

In a possible implementation manner, if the network device does not perform the implementation procedure of step S801 shown in fig. 8a, i.e. the terminal device does not obtain the indication information, when the terminal device triggers to enter the inactive state and/or the idle state due to receiving the RRC Release message, the terminal device will Release the auxiliary data information by default. An implementation example is shown in fig. 8b, taking a terminal device as UE, a network device as RAN, and auxiliary data information as AD as an example, specifically including the following steps:

the ue acquires AD (i.e., assistance data information) through LPP or PosSIB.

The ran sends an RRC Release to the UE.

A3.ue releases AD.

Thus, compared to the implementation of the UE default releasing the assistance information (which may include the assistance data information received by the UE from the LMF through the LPP message and/or the assistance data information acquired by the UE from the PosSIB) when the UE receives the RRC Release message sent by the base station in the implementation shown in fig. 8b, in fig. 8a, the terminal device may retain the assistance data information based on the indication (i.e. the indication information) of the network device, so as to avoid the situation that the terminal device cannot measure due to the default releasing the assistance data information when entering the inactive state and/or the idle state, and implement positioning of the terminal device when entering the inactive state and/or the idle state.

In one possible implementation, the indication information is carried in a provide assistance data providing message or a radio resource control release message. Specifically, the indication information is carried in the auxiliary data providing message or the radio resource control release message, so that signaling consumption is saved, and communication efficiency is improved.

Based on the technical solution shown in the first embodiment, the network device indicates to the terminal device that the auxiliary data information is reserved when entering the inactive state and/or the idle state, so as to solve the problem that the terminal device cannot measure due to default release of the auxiliary data information when entering the inactive state and/or the idle state.

Example two

Referring to fig. 9a, another schematic diagram of a communication method provided in the present application is shown, and the method includes the following steps.

And S901, the network equipment generates third information.

And S902, the network equipment sends third information to the terminal equipment. Wherein the third information may indicate release of the auxiliary data information by means of a hidden or displayed way.

It should be noted that, the step S901 is an optional step. For example, the network device may perform step S902 after generating the third information in step S901, or the network device may perform step S902 after receiving the third information from another network device.

S903, the terminal equipment releases the auxiliary data information based on the third information.

Based on the technical scheme shown in fig. 9a, after the terminal device receives the third information sent by the network device, the terminal device can release the auxiliary data information based on the third information, so that the terminal device can timely release the auxiliary data information, thereby releasing the storage resources of the terminal device and reducing the energy consumption waste caused by the loading of the storage information.

In one possible implementation, the third information includes a mobile originated location request (mobile originated location request, MO-LR) response (response) message, a cancel location acknowledgement (cancel location acknowledgement, cancel location ACK) message, or a cancel location (cancel location). Specifically, the third information may include a mobile originated location request response message for indicating a request for location, a cancel location confirmation message for indicating a location cancel response, or a cancel location message for indicating a location cancel, without additional information indication, so as to save signaling consumption and improve communication efficiency.

Various implementation cases of the third information will be exemplarily described below through implementation procedures shown in fig. 9b, 9c and 9 d. In the following implementation examples, the terminal device is taken as a UE, and the network device includes an AMF or an LMF as an example.

In a first case, please refer to fig. 9b, which is another schematic diagram of a communication method provided in the present application, the method includes the following steps.

The amf sends a mobile originated location request (mobile originated location request, MO-LR) request (request) to the UE.

And B2, performing a UE positioning process between the UE and the AMF.

B3.amf sends MO-LR response to UE.

B4.ue releases AD.

In the implementation process shown in fig. 9B, in the positioning service initiated by the UE, when the UE receives the positioning result of the positioning service (i.e. the UE receives the MO-LR response in step B3), the UE determines that the positioning service is ended, and releases the AD resource. Specifically, when the UE receives a mobile originated location request (mobile originated location request, MO-LR) response (response) message sent by the AMF, the UE determines that the location service is ended. In other words, the UE releases the AD based on the third information (i.e., MO-LR response message).

In a second case, please refer to fig. 9c, which is another schematic diagram of a communication method provided in the present application, the method includes the following steps.

C1.ue sends a cancel location to LMF.

C2.lmf sends cancel location ACK to UE.

Ue releases AD.

As shown in the implementation procedure of fig. 9c, when the UE determines that the positioning needs to be canceled, the UE sends a cancel positioning (cancel positioning) message to the LMF, and receives a cancel positioning confirmation (cancel location ACK) message of the LMF, and then the UE determines that the positioning service is finished. In other words, the UE releases the AD based on the third information (i.e., cancel location ACK).

In a third case, please refer to fig. 9d, which is another schematic diagram of a communication method provided in the present application, the method includes the following steps.

The AMF sends a cancel location to the UE.

D2.ue sends cancel location ACK to AMF.

D3.ue releases AD.

As shown in the implementation process of fig. 9d, after receiving a cancel location (cancel location) message sent by the AMF, the UE determines that the location service needs to be cancelled, and sends a location cancel response (cancel location ACK) message to the AMF. In other words, the UE releases the AD based on the third information (i.e., the cancel location).

In addition, the third information may be implemented by the network device based on the display indication, in addition to the implementation of the network device based on the implicit indication shown in fig. 9b, 9c and 9 d. For example, the third information may be used to indicate release of assistance data information carried in the PosSIB and/or assistance data information carried in the LPP message. Specifically, the terminal device may release specific auxiliary data information based on the indication (i.e., the third information) of the network device, so that the terminal device may timely release the auxiliary data information carried in the PosSIB and/or the auxiliary data information carried in the LPP message, so as to release the storage resource of the terminal device and reduce the energy consumption waste caused by loading the storage information.

Illustratively, the network device includes an LMF. The UE may also release the AD based on the display indication of the network device. For example, the LMF may instruct the UE to release the AD through an LPP message. For example, the LMF may instruct the UE to release the AD by adding a new cell in the Provide Assistance Data message. For example, adding a new cell, e.g., a releasesasitancedata cell, in the message indicates the distance the UE releases the AD.

Optionally, the third information may be used to indicate to release downlink reference signal resource information corresponding to at least one of the following information in the auxiliary data information: frequency layer information, transmission reception point TRP information, positioning reference signal index or positioning reference signal resource set index. Specifically, the terminal device may release specific downlink reference signal configuration information included in the auxiliary data information based on the indication (i.e., the third information) of the network device, so that the terminal device may timely release the downlink reference signal resource information corresponding to the at least one item of information, so as to release the storage resource of the terminal device and reduce energy consumption waste caused by loading the storage information.

Optionally, the third information is carried in a provide assistance data providing message or a radio resource control release message. Specifically, the third information is carried in the auxiliary data message or the radio resource control release message, so as to save signaling consumption and improve communication efficiency.

Based on the technical scheme shown in the second embodiment, the network device indicates to the terminal device to release the auxiliary data information, so as to solve the problem that when the terminal device includes the auxiliary data information, the terminal device may not need the auxiliary data information, so that the terminal device wastes storage resources of the terminal device and energy consumption of the terminal device due to reservation of the auxiliary data information.

Example III

Referring to fig. 10a, another schematic diagram of a communication method provided in the present application includes the following steps.

S1001, the network equipment generates second indication information, wherein the second indication information is used for indicating to reserve or release auxiliary data information, and the auxiliary data information comprises downlink reference signal configuration information.

S1002, the network equipment sends second indication information to the terminal equipment.

S1003, the terminal equipment reserves or releases auxiliary data information based on the second indication information.

Based on the technical solution shown in fig. 10a, after receiving the second indication information, the terminal device may reserve the auxiliary data information based on the indication of the network device (i.e. the second indication information) to implement positioning, or the terminal device may release the auxiliary data information based on the indication of the network device (i.e. the second indication information) to release the storage resources of the terminal device and reduce the energy consumption waste caused by loading the storage information, so that the terminal device may explicitly reserve or release the auxiliary data information based on the indication of the network device.

In one possible implementation, the second indication information is carried in a provide assistance data providing message or a radio resource control release message. Specifically, the second indication information is carried in the auxiliary data providing message or the radio resource control release message, so that signaling consumption is saved, and communication efficiency is improved.

As an implementation example, the second indication information is carried in a radio resource control release message as an example, please refer to fig. 10b, which is another schematic diagram of a communication method provided in the present application, and the method includes the following steps.

The lmf sends NPRRa msg to the RAN.

The ran sends an RRC Release to the UE.

Ue retains/releases AD.

Specifically, the LMF first releases or retains the assistance data via a new radio positioning protocol a message (new radio positioning protocol A massage, NRPPa msg) to instruct the UE (upon entering the INACTIVE/IDLE state). After the base station receives the NRPPa msg, adding indication information for releasing or reserving the AD in an RRC Release message sent to the UE, so that the UE reserves/releases the AD in step E3.

Based on the technical scheme shown in the third embodiment, the network device indicates to the terminal device to reserve or release the auxiliary data information, so as to solve the problem that the terminal device cannot locate or waste resources because the terminal device does not explicitly need to reserve or release the auxiliary data information when the terminal device contains the auxiliary data information.

Example IV

Referring to fig. 11, another schematic diagram of a communication method provided in the present application includes the following steps.

S1101. the network device sends second priority information to the terminal device, where the second priority information is used to indicate a priority of first information, where the first information is associated with downlink reference signal resource information, and the first information includes at least one of the following: and transmitting the TRP information of the receiving point by using the frequency layer information, and downlink reference signal index or downlink reference signal resource set index.

In other words, for a certain downlink reference signal resource information, the first information may include at least one of frequency layer information of the downlink reference signal resource information, transmission reception point TRP information, downlink reference signal index, and downlink reference signal resource set index.

S1102, the terminal equipment measures the downlink reference signal based on the second priority information and the downlink reference signal resource information to obtain a measurement result.

And S1103, the terminal equipment sends the measurement result to the network equipment.

Based on the technical solution shown in fig. 11, after the terminal device receives the second priority information for indicating the priority of the first information in step S1101, the measurement result sent by the terminal device in step S1103 is a measurement result corresponding to the downlink reference signal resource information, where the first information may be associated with the downlink reference signal resource information, so that the terminal device determines the measurement result based on the second priority information for indicating the first information. Therefore, in a communication scene that the terminal equipment comprises at least two pieces of downlink reference signal resource information, the terminal equipment can realize downlink reference signal measurement based on the second priority information and the at least two pieces of downlink reference signal resource information. Optionally, the terminal device may receive the assistance data information, and may include one or more assistance data information carried in the PosSIB, and one or more assistance data information carried in the LPP message. The downlink reference signal configuration information included in the auxiliary data information includes the downlink reference signal resource information.

In a possible implementation manner, the process of measuring the downlink reference signal by the terminal device based on the second priority information and the downlink reference signal resource information in step S1102, to obtain a measurement result may include: and the terminal equipment sequentially measures the downlink reference signals corresponding to the downlink reference signal resource information based on the second priority information to obtain a measurement result. Specifically, the terminal device may sequentially measure downlink reference signals corresponding to at least two downlink reference signal resource information associated with the first information based on the priority of the first information indicated by the second priority information, so as to obtain the measurement result. A specific implementation of downlink reference signal measurement is provided.

In one possible implementation, the second priority information is carried in a request for positioning information message or in a provide assistance data message. Specifically, the second priority information may be carried in a positioning request information message for requesting positioning or an auxiliary data providing message for carrying auxiliary data information, so as to save signaling consumption and improve communication efficiency.

In one possible implementation, the second priority information includes at least one of:

the priority of the first information takes a value.

As an implementation example, the first information includes frequency layer (frequency layer) information, the network device includes an LMF, and the terminal device is described as a UE as an example.

For example, the auxiliary information sent by the LMF to the UE includes PRS resource information of a plurality of frequency layers. The embodiment can solve the problem of how to select the priority of PRS resources of a plurality of frequency layers by the UE. Specifically, the present embodiment proposes that the LMF may indicate the priority of PRS resources of different frequency layers used when sending request positioning information (request location information) to request positioning measurement. Alternatively, in providing the positioning information (Provide Location Information) message, PRS resource priorities of different frequency layers are indicated.

Taking the example of providing a location information message, a new cell may be added to indicate priority. For example, an auxiliary data priority (assuredly) cell is added, and the cell contains a list of frequency layers, which represents the priority of the frequency layers.

Optionally, the auxiliary data priority cell includes a frequency layer list, and each frequency layer under the list includes frequency point information (identified by ARFCN) to indicate a frequency point of the frequency layer. The list represents the priority of the frequency layer.

Optionally, each frequency layer contains a list of TRP priorities, representing the priorities of PRS resources of different TRPs. At least one item of information of PRS identification, cell identification and frequency point (expressed by ARFCN) is contained under each TRP.

Alternatively, without indication information, the LMF may implicitly indicate the priority of PRS resources of different frequency layers through existing messages and existing cells. When the LMF sends auxiliary data to the UE, a new air interface-selective downlink-positioning reference signal-index list (NR-selected dl-PRS-index list) cell may be sent, where the cell includes PRS resources selected by the LMF to indicate the UE, including PRS resource lists of different frequency layers. In this embodiment, it is proposed that, when receiving a message carrying the assistance data information provided by the cell, the UE selects, according to the new air interface, a frequency layer list in the downlink-positioning reference signal-index list cell as a priority of PRS resources of different frequency layers.

Alternatively, the LMF may also select a new air interface-select downlink-positioning reference signal-index list cell in which each frequency layer in the frequency layer list indicates a priority value. The priority value characterizes the priority of use of PRSs for the frequency layer. Alternatively, a priority cell may be added to the new air interface-selective downlink-positioning reference signal-index list cell, the value of which characterizes the priority. For example, the prioritized cell is a new air-interface-selected downlink-positioning reference signal-frequency domain layer priority (NR-selected DL-PRS-FrequencyLayerPrior priority).

Alternatively, a priority may be assigned to the PRS resource of each TRP, e.g., adding a cell to the new air-select downlink-positioning reference signal-index each TRP (NR-selected dl-PRS-IndexPerTRP) cell. For example, the prioritized cell may be a new air-interface-selected downstream TRP priority (nr-selected TRP priority).

Based on the technical scheme shown in the fourth embodiment, the network device indicates the second priority information to the terminal device, so that the terminal device can preferentially use the better downlink reference signal resource information to perform measurement based on the second priority information, thereby avoiding the terminal device from using the worse downlink reference signal resource information to perform measurement and realizing efficient positioning measurement. In addition, the technical scheme can be used for solving the problem that in the process of using at least two downlink reference signal resource information to measure the downlink reference signal, the accuracy of positioning measurement is reduced because the terminal equipment is ambiguous about which resource should be used preferentially.

The present application is described above in terms of a method, and the apparatus according to the present application will be described below.
