[0181] Step S2101: The core network device 101, such as LMF, sends a first message to the access network device 102.

[0182] In some embodiments, the access network device 102 receives the first message.

[0183] In some embodiments, the first message is used to request the access network device to perform measurement and report the measurement result according to the uplink positioning reference signal frequency hopping configuration.

[0184] In some embodiments, the uplink positioning reference signal may be an uplink positioning reference signal sent by the terminal 103 , including but not limited to a channel sounding reference signal (Sounding Reference Signal, SRS).

[0185] In some embodiments, terminal 103 transmits an uplink positioning reference signal by frequency hopping. For example, as shown in FIG2B , terminal 103 transmits the uplink positioning reference signal by frequency hopping, which may involve terminal 103 transmitting the uplink positioning reference signal on different frequency domain resources at different time points. Frequency hopping allows access network device 102 to measure the uplink positioning reference signal over a wider bandwidth, thereby improving positioning accuracy.

[0186] When the terminal 103 transmits the uplink positioning reference signal by frequency hopping, two adjacent hops may have a gap in the time domain and may overlap in the frequency domain.

[0187] In some embodiments, the uplink positioning reference signal frequency hopping configuration refers to the configuration related to the frequency hopping transmission of the uplink positioning reference signal by the terminal 103, including but not limited to time domain information transmission, frequency domain information transmission, etc.

[0188] In some embodiments, the access network device 102 performs measurement according to the uplink positioning reference signal frequency hopping configuration, and the obtained measurement results include but are not limited to at least one of the following:

[0189] Measurement result value; timestamp; measurement quality; measurement beam information; uplink positioning reference signal resource type; Address Resolution Protocol (ARP) identifier; channel model information.

[0190] Among them, the measurement result value may include but is not limited to at least one of the following: uplink arrival angle; reference signal receiving power (RSRP) of the uplink positioning reference signal; uplink relative arrival time (UL RTOA); sending and receiving time difference of the access network device 102; vertical angle of arrival (z-AOA); multiple uplink arrival angles.

[0191] It should be noted that the above measurement results are associated with the uplink positioning reference signal frequency hopping configuration.

[0192] In some embodiments, the name of the first message is not limited, and it can be, for example, a request message, a request signaling, a first signaling, etc.

[0193] In some embodiments, the first message may be a New Radio Positioning Protocol a (NRPPa) message.

[0194] In some embodiments, the first message may be a measurement request (MEASUREMENT REQUEST) message.

[0195] In some embodiments, the MEASUREMENT REQUEST message is sent by the core network device 101, such as the LMF, to request the access network device 102, such as the Next Generation Radio Access Network (NG-RAN) node to configure positioning measurements.

[0196] In some embodiments, the first message may include first frequency hopping information of the uplink positioning reference signal that the access network device 102 is requested to measure.

[0197] In some embodiments, the first frequency hopping information includes but is not limited to at least one of the following: the starting frequency domain unit index and the number of frequency domain units included in the uplink positioning reference signal resource; the starting time unit and the number of time units included in the uplink positioning reference signal resource; the cycle duration and offset; the uplink positioning reference signal sequence identifier; the number of frequency hops; the number of time units between two adjacent hops; the number of frequency domain units overlapping between two adjacent hops; and the frequency hopping index.

[0198] In one example, the frequency domain unit may be a resource block (RB).

[0199] In one example, the time unit may be a time slot, an Orthogonal Frequency Division Multiplexing (OFDM) symbol, or a span, which is not limited in the present disclosure. A span includes multiple consecutive symbols.

[0200] In an example, the cycle duration refers to the length of the cycle in which the terminal 103 frequency hops to send the uplink positioning reference signal, and the offset refers to the offset of the start time unit relative to the cycle start time unit.

[0201] In one example, the frequency hopping number refers to the number of frequency hopping times used by the terminal 103 to send the uplink positioning reference signal.

[0202] In an example, the frequency hopping index may be a positive integer, such as 1, 2, ..., corresponding to indicating the first hop, the second hop, ...

[0203] In some embodiments, the first frequency hopping information may include but is not limited to at least one of the following: one or more frequency hopping group identifiers; and one or more uplink positioning reference signal resource identifiers.

[0204] The first frequency hopping information is multiplexed with an uplink positioning reference signal resource identifier for indication.

[0205] Exemplarily, each frequency hopping group identifier corresponds to one or more uplink positioning reference signal resource identifiers.

[0206] For example, frequency hopping group #1 corresponds to uplink positioning reference signal resource #1 and uplink positioning reference signal resource #2, and the first frequency hopping information sent by the core network device 101 includes frequency hopping group identifier 1, then the access network device 102 determines that the first frequency hopping information indicated by the core network device 101 includes uplink positioning reference signal resource #1 and uplink positioning reference signal resource #2.

[0207] Exemplarily, when there are multiple frequency hopping group identifiers, they may be sent to the access network device 102 in a list format.

[0208] Exemplarily, the core network device 101 directly sends one or more uplink positioning reference signal resource identifiers to the access network device 102 .

[0209] There are one or more uplink positioning reference signal resource identifiers, and the core network device 101 may provide the multiple uplink positioning reference signal resource identifiers to the access network device 102 through an uplink positioning reference signal resource identifier list.

[0210] For example, the first frequency hopping information sent by the core network device 101 includes uplink positioning reference signal resource #1 and uplink positioning reference signal resource #2.

[0211] In some embodiments, the first frequency hopping information may be carried in an SRS configuration information element of the measurement request message.

[0212] In some embodiments, access network device 102 configures frequency hopping information of an uplink positioning reference signal for terminal 103, and then provides the frequency hopping information configured for terminal 103 to core network device 101. If core network device 101 sends all the frequency hopping information of the uplink positioning reference signal configured for terminal 103 as first frequency hopping information to access network device 102 via a first message, the first message is used to request access network device 102 to measure each hop of the uplink positioning reference signal and report the measurement result. Exemplarily, access network device 102 measuring each hop of the uplink positioning reference signal means that access network device 102 measures the uplink positioning reference signal according to the frequency hopping information of the uplink positioning reference signal and obtains the corresponding measurement result.

[0213] In some embodiments, the access network device 102 configures the frequency hopping information of the uplink positioning reference signal for the terminal 103, and then provides the above-mentioned frequency hopping information configured for the terminal 103 to the core network device 101. If the core network device 101 sends part of the frequency hopping information configured for the terminal 103 as the first frequency hopping information through the first message to the access network device 102, then the first message is used to request the access network device 102 to measure the specified hop of the uplink positioning reference signal and report the measurement results.

[0214] For example, the core network device 101 provides the frequency hopping information of the second and third hops as the first frequency hopping information to the access network device 102 through the first message. The first message is used to request the access network device 102 to measure the second and third hops of the uplink positioning reference signal and report the measurement results.

[0215] In some embodiments, the first message includes second frequency hopping information of a designated uplink positioning reference signal that the access network device 102 is requested to measure.

[0216] In some embodiments, the second frequency hopping information of the designated uplink positioning reference signal may include information related to the designated hop of the uplink positioning reference signal.

[0217] In one example, the second frequency hopping information includes, but is not limited to, at least one of the following: a list of uplink positioning reference signal resource identifiers; a list of frequency hopping indices; a number of hopping frequencies; one or more frequency hopping group identifiers; a reporting method for measurement results; and a reporting condition for measurement results. Each of the frequency hopping group identifiers corresponds to one or more uplink positioning reference signal resource identifiers.

[0218] When there are multiple frequency hopping group identifiers, they may be provided to the access network device 102 in a list format.

[0219] The reporting method includes but is not limited to individual reporting or combined reporting. Individual reporting means that each measurement result can be reported individually, and combined reporting means that multiple measurement results are reported together.

[0220] Among them, the reporting conditions include but are not limited to the reporting time period, reporting time point, etc.

[0221] In some embodiments, the first message may include a first information unit, where the first information unit is used to indicate the second frequency hopping information.

[0222] In some embodiments, the first message may include a second information unit, which may be used to indicate the characteristics requested for measurement. For example, the second information unit is a Measurement Characteristics Request Indicator information unit, which is used to carry the second frequency hopping information.

[0223] In some embodiments, the first message may include first frequency hopping information and second frequency hopping information.

[0224] In one example, the first frequency hopping information may include configuration information of uplink positioning reference signal multi-hops. The second frequency hopping information is used to request the access network device 102 to perform measurement based on a specified hop in the configured multi-hops and report the measurement result.

[0225] In some embodiments, when the core network device 101 requests multiple measurement results, it may instruct the access network device 102 to associate different measurement results with different frequency hopping information. Exemplarily, associating different measurement results with different frequency hopping information means measuring the uplink positioning reference signal according to the associated frequency hopping information to obtain the corresponding measurement results.

[0226] For example, the measurement results requested by core network device 101 include uplink angle of arrival, RSRP of the uplink positioning reference signal, UL RTOA, and z-AOA. The uplink angle of arrival can be associated with the first hop, RSRP can be associated with the first and second hops, UL RTOA can be associated with the third hop, and z-AOA can be associated with the fourth hop. For example, when measuring RSRP, the first and second hops of the uplink positioning reference signal are measured.

[0227] In some embodiments, when the core network device 101 requests multiple measurement results, it may instruct the access network device 102 to associate different measurement results with the same frequency hopping information. For example, the core network device 101 provides the access network device 102 with frequency hopping information of an uplink positioning reference signal, and the access network device 102 uses the frequency hopping information when measuring all measurement results requested by the core network device 101.

[0228] In step S2102, the access network device 102 measures the uplink positioning reference signal based on the instruction of the first message to obtain the measurement result.

[0229] In some embodiments, the first message includes first frequency hopping information, the access network device 102 determines that the first frequency hopping information includes all frequency hopping information configured for the terminal 103, and the access network device 102 measures each hop of the uplink positioning reference signal to obtain a measurement result.

[0230] In one example, the measurement results include but are not limited to at least one of the following:

[0231] Measurement result value; timestamp; measurement quality; measurement beam information; uplink positioning reference signal resource type; ARP identifier; channel model information.

[0232] The measurement result value may include but is not limited to at least one of the following: uplink arrival angle; RSRP of uplink positioning reference signal; UL RTOA; sending and receiving time difference of access network device 102; z-AOA; multiple uplink arrival angles.

[0233] In some embodiments, the first message includes first frequency hopping information. Access network device 102 determines that the first frequency hopping information includes all frequency hopping information configured for terminal 103. Access network device 102 measures each hop of the uplink positioning reference signal to obtain a measurement result. For example, the first frequency hopping information includes the first hop and the second hop. Access network device 102 measures the first hop and the second hop to obtain an RSRP value.

[0234] In some embodiments, the first message includes first frequency hopping information. The access network device 102 determines that the first frequency hopping information includes part of the frequency hopping information configured for the terminal 103, such as the frequency hopping information of the designated hop. The access network device 102 measures the designated hop of the uplink positioning reference signal to obtain the measurement result.

[0235] In some embodiments, the first message includes second frequency hopping information, and the access network device 102 measures a designated hop of the uplink positioning reference signal to obtain a measurement result.

[0236] In some embodiments, the first message includes first frequency hopping information and second frequency hopping information. The access network device 102 determines the multi-hop configuration of the uplink positioning reference signal based on the first frequency hopping information, and measures the designated hop of the uplink positioning reference signal based on the second frequency hopping information to obtain a measurement result.

[0237] In one example, the measurement results include but are not limited to at least one of the following:

[0238] Measurement result value; timestamp; measurement quality; measurement beam information; uplink positioning reference signal resource type; ARP identifier; channel model information.

[0239] The measurement result values ​​have been introduced in the above embodiments and will not be repeated here.

[0240] In some embodiments, when the core network device 101 requests multiple measurement results, it instructs the access network device 102 to associate different measurement results with different frequency hopping information.

[0241] The access network device 102 uses the frequency hopping information when measuring all measurement results requested by the core network device 101 .

[0242] For example, the measurement results requested by core network device 101 include uplink angle of arrival, RSRP of the uplink positioning reference signal, UL RTOA, and z-AOA. The uplink angle of arrival can be associated with the first hop, RSRP can be associated with the first and second hops, UL RTOA can be associated with the third hop, and z-AOA can be associated with the fourth hop. The access network device can measure the first hop of the uplink positioning reference signal when measuring the uplink angle of arrival, the first and second hops of the uplink positioning reference signal when measuring RSRP, the third hop of the uplink positioning reference signal when measuring UL RTOA, and the fourth hop of the uplink positioning reference signal when measuring z-AOA, to obtain the corresponding measurement results.

[0252] In some embodiments, the second message includes a fourth information unit, which is a transmission reception point (TRP) measurement result (TRP Measurement Result) information unit, which includes the transmission reception point measurement result.

[0315] It should be noted that the difference between step 3301 and step S2101 lies in the different execution entities. The execution entity of step S2101 is the core network device 101, and the execution entity of step 3301 is the terminal 103.

[0316] In some embodiments, step S3301 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, if the access network device 102 measures the uplink positioning reference signal frequency hopping configuration and reports the measurement results based on the request of the core network device 101, step S3301 may not be performed.

[0317] In the above embodiment, the terminal can request the access network device to perform measurement according to the uplink positioning reference signal frequency hopping configuration, thereby improving the flexibility and reliability of positioning measurement and improving the accuracy and reliability of uplink positioning and uplink and downlink hybrid positioning.

[0318] The above solution provided in the embodiment of the present disclosure is further illustrated below with examples.

[0319] The core network device 101, such as the LMF, can request the access network device 102, such as the gNB, to perform measurements based on the uplink positioning reference signal frequency hopping configuration and report the measurement results.

[0320] In some embodiments, the measurement request message sent by the LMF to the gNB includes first frequency hopping information, and the first frequency hopping information is included in the SRS configuration information element.

[0321] Exemplarily, the first frequency hopping information includes at least one of the following:

[0322] The starting frequency domain unit index and the number of frequency domain units included in the uplink positioning reference signal resource;

[0326] Number of frequency hopping;

[0327] The number of time units between two adjacent hops;

[0335] In some embodiments, the (uplink positioning reference signal) frequency hopping group identifier of the present disclosure may be equivalent to the (uplink positioning reference signal) frequency hopping identifier. For example, when one frequency hopping group identifier corresponds to one uplink positioning reference signal resource, the frequency hopping group identifier and the frequency hopping identifier may be equivalent.

[0336] In some embodiments, the frequency hopping group identifier of the present disclosure may correspond to multiple frequency hopping identifiers. For example, an uplink positioning reference signal resource identifier corresponds to an uplink positioning reference signal frequency hopping identifier one-to-one, and each frequency hopping group identifier corresponds to multiple frequency hopping identifiers.

[0337] In some embodiments, the uplink positioning reference signal resource identifier and the uplink positioning reference signal frequency hopping identifier may be identical, for example, the uplink positioning reference signal resource identifier and the uplink positioning reference signal frequency hopping identifier have a one-to-one correspondence.

[0338] In some embodiments, the uplink positioning reference signal resource identifier and the uplink positioning reference signal frequency hopping identifier may not be identical. For example, the correspondence between the uplink positioning reference signal resource identifier and the uplink positioning reference signal frequency hopping identifier is one-to-many or many-to-one.

[0339] The gNB measures each hop of the uplink positioning reference signal and sends the measurement result to the LMF. Or the gNB measures each hop of the uplink positioning reference signal and sends a measurement result to the LMF.

[0340] In some embodiments, the measurement request message sent by the LMF to the gNB includes frequency hopping information of a specified uplink positioning reference signal that the gNB is requested to measure, for example, the measurement request message includes second frequency hopping information.

[0341] In an example, a new information element may be added to the measurement request message to indicate the second frequency hopping information.

[0342] In one example, the second frequency hopping information may be indicated in a Measurement Characteristics Request Indicator information element in the measurement request message.

[0343] In one example, the second frequency hopping information may be associated with different measurement results. For example, when the LMF requests multiple measurement results at a time, it may instruct the gNB to associate different frequency hopping information with different measurement results.

[0344] In the disclosed embodiment, the gNB measures the uplink positioning reference signal based on the second frequency hopping information and reports the corresponding measurement result.

[0356] The gNB reports the measurement result in the measurement response message and indicates the third hopping frequency information corresponding to the measurement result.

[0357] In one example, a new information unit is added to the measurement response message to indicate the third frequency hopping information corresponding to the measurement result.

[0358] In one example, a new information element is added to the TRP Measurement Result information element of the measurement response message to indicate the third frequency hopping information corresponding to the measurement result.

[0359] In an example, different third frequency hopping information may correspond to different measurement results.

[0360] Exemplarily, the third frequency hopping information corresponding to each specific measurement result is indicated, for example, the corresponding third frequency hopping information is indicated in the measurement results such as SRS-RSRP and UL-RTOA; or

[0361] The third frequency hopping information is indicated in the TRP Measurement Result information element. In this case, one or more measurement results correspond to the third frequency hopping information.

[0373] Frequency hopping identifier list;

[0374] Uplink positioning reference signal resource identifier list.

[0375] The frequency hopping group identifier list may include one or more frequency hopping group identifiers, wherein the frequency hopping group identifier corresponds to one or more uplink positioning reference signal resource identifiers.

[0376] Alternatively, the frequency hopping group identifier list may include one or more uplink positioning reference signal resource identifiers and / or uplink positioning reference signal frequency hopping identifiers, wherein the uplink positioning reference signal resource identifiers and the uplink positioning reference signal frequency hopping identifiers have a one-to-one correspondence.

[0377] The frequency hopping identifier list includes one or more frequency hopping identifiers, and the uplink positioning reference signal resource identifier corresponds to the uplink positioning reference signal frequency hopping identifier one by one.

[0378] The number of uplink positioning reference signal resources is one or more, and may be sent in a list format, that is, multiple uplink positioning reference signal resource identifiers are provided to the core network device through an uplink positioning reference signal resource identifier list.

[0379] In the above embodiment, the access network device can perform measurements and report measurement results based on the uplink positioning reference signal frequency hopping configuration according to the request of the core network device, thereby improving the flexibility and reliability of positioning measurement, and improving the accuracy and reliability of uplink positioning and uplink and downlink hybrid positioning.
