[0155] In some embodiments, the first information may be, for example, configuration information, PRS configuration information, reference signal resource configuration information, resource configuration information, reference signal configuration information, resource set configuration information, etc., but is not limited thereto.

[0156] In some embodiments, the network device may send the first information to the terminal device based on Radio Resource Control (RRC) signaling or based on Downlink Control Information (DCI). Optionally, the terminal device may receive the first information sent by the network device.

[0157] S2102, the network device sends third information.

[0158] In some embodiments, the third information is used to configure a setting condition that the first positioning reference signal resource needs to meet.

[0159] In some embodiments, the network device may send the third information to the terminal device based on Radio Resource Control (RRC) signaling or based on Downlink Control Information (DCI). Optionally, the terminal device may receive the third information sent by the network device.

[0160] In some embodiments, positioning reference signal resources used for carrier aggregation generally need to meet certain conditions. Optionally, different positioning reference signal resources that meet the conditions can be used for carrier aggregation to transmit positioning reference signals.

[0161] In some embodiments, the set conditions may include but are not limited to:

[0162] Different positioning reference signal resources have the same time domain location, for example, in the same slot, in the same symbols, or at a symbol location within one slot.

[0163] Different positioning reference signal resources have the same transmission and receiving point (TRP);

[0164] Different positioning reference signal resources have the same antenna reference point (ARP);

[0165] Different positioning reference signal resources have the same radio frequency (RF) chain;

[0166] Different positioning reference signal resources have the same time domain position length (for example, the same number of symbols (nrofSymbols), the same number of symbols);

[0167] Different positioning reference signal resources have the same repetition factor;

[0168] Different positioning reference signal resources have the same period;

[0169] Different positioning reference signal resources have the same time domain offset value (such as the same time slot offset value, NR-DL-PRS-SFN0-Offset, etc.);

[0170] Different positioning reference signal resources have the same muting pattern;

[0171] Different positioning reference signal resources have the same parameter numerology, for example, the same cyclic prefix (CP) and sub-carrier spacing (SCS).

[0173] Different positioning reference signal resources have the same comb value comb-size;

[0174] Different positioning reference signal resources have the same number of reference signal resource sets;

[0175] Different positioning reference signal resources have the same subcarrier energy.

[0176] Optionally, the first positioning reference signal resource may be understood as a positioning reference signal resource that meets the above conditions and can be used for carrier aggregation (bandwidth aggregation).

[0177] In some embodiments, the third information may be, for example, condition configuration information, condition indication information, etc., but is not limited thereto.

[0178] In some embodiments, step S2101 and step S2102 may be executed sequentially or one after another, for example, step S2101 may be executed first, and then step S2102; for another example, step S2102 may be executed first, and then step S2101.

[0179] S2103: The terminal device determines that a positioning reference signal resource that meets a set condition among the positioning reference signal resources is a first positioning reference signal resource for carrier aggregation.

[0180] In some embodiments, a reference signal resource that meets a set condition in a reference signal resource set on different carriers may be determined as a first positioning reference signal resource for carrier aggregation.

[0181] Through the above-mentioned setting conditions, it is possible to clearly determine which reference signal resources are used for carrier aggregation from the reference signal resource sets of different carriers. Subsequently, carrier aggregation transmission can be successfully implemented based on the reference signal resource that meets the conditions in the reference signal resource sets on each carrier, thereby improving the service processing accuracy in the communication system. For example, when the reference signal sent is a reference signal for positioning purposes, the positioning accuracy can be improved.

[0182] For example, assuming reference signal resource set #a on carrier #1, reference signal resource set #b on carrier #2, and reference signal resource set #c on carrier #3, a first positioning reference signal resource that meets the conditions among reference signal resource set #a on carrier #1, reference signal resource set #b on carrier #2, and reference signal resource set #c on carrier #3 can be determined based on a set condition. For example, a positioning reference signal resource that meets the conditions of "the same time domain position, the same TRP, and the same ARP" among reference signal resource set #a on carrier #1, reference signal resource set #b on carrier #2, and reference signal resource set #c on carrier #3 can be determined as the first positioning reference signal resource.

[0183] S2104, the terminal device performs positioning measurement based on the first positioning reference signal resource and reports second information.

[0184] In some embodiments, the first positioning reference signal resource can transmit a reference signal based on carrier aggregation, that is, the first positioning reference signal resource in the reference signal resource set on different carriers can be carrier aggregated to transmit the reference signal, that is, the network device can aggregate and send PRS or SRS based on the first positioning reference signal resource, and the terminal device can measure the reference signal on the first positioning reference resource in the reference signal resource set on different carriers to obtain a measurement result.

[0185] In some embodiments, the terminal device may perform carrier aggregation based on the first reference signal resource to transmit a reference signal for positioning measurement to obtain a measurement result.

[0186] In some embodiments, the above measurement result may be at least one of the following:

[0187] Reference Signal Time Difference (RSTD);

[0188] Rx-Tx time difference;

[0189] Reference Signal Received Power (RSRP);

[0190] Reference Signal Received Path Power (RSRPP)

[0191] In some embodiments, there may be multiple first positioning reference signals, and one measurement result is obtained from multiple first positioning reference signal resources.

[0192] For example, assume that the first information configures reference signal resource sets on carrier #a and carrier #b, where the reference signal resource sets on carrier #a are: reference signal resource set #1, reference signal resource set #2, and reference signal resource set #3; and the reference signal resource sets on carrier #b are: reference signal resource set #4 and reference signal resource set #5. The terminal device can determine the first reference signal resources in reference signal resource set #1 and reference signal resource set #4 according to the conditions set in the third information, and use the first positioning reference signal resources in reference signal resource set #1 and reference signal resource set #4 to aggregate and transmit a PRS or SRS. In other words, a single measurement result is obtained for the first positioning reference signal resources in both sets.

[0193] In some embodiments, the terminal device may report the measurement result to the network device based on the second information. In some embodiments, the second information may be, for example, reporting information, measurement reporting information, result reporting information, etc., but is not limited thereto.

[0194] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

In some embodiments, the terms "radio," "wireless," "radio access network (RAN)," "access network (AN)," and "RAN-based" may be used interchangeably.

[0196] In some embodiments, terms such as "certain", "preset", "preset", "setting", "indicated", "a certain", "any", and "first" can be interchangeable. "Specific A", "preset A", "preset A", "setting A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-specified in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., or as specific A, a certain A, any A, or first A, etc., but not limited to this.

[0197] The positioning measurement method involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2104. For example, step S2104 may be implemented as an independent embodiment, steps S2101+S2102+S2103 may be implemented as an independent embodiment, steps S2102+S2103 may be implemented as an independent embodiment, and steps S2102+S2103+S2104 may be implemented as an independent embodiment, but are not limited thereto.

[0198] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0199] FIG2B is an interactive diagram of a positioning measurement method according to an embodiment of the present disclosure. As shown in FIG2B , the embodiment of the present disclosure relates to a positioning measurement method, which includes:

[0200] S2201, the network device sends first information.

[0201] The optional methods of step S2201 can refer to the optional methods of step S2101 in Figure 2A and other parts of the embodiment involved in Figure 2A, which will not be repeated here.

[0202] S2202: The network device sends third information.

[0203] The optional methods of step S2202 can refer to the optional methods of step S2102 in Figure 2A and other parts of the embodiment involved in Figure 2A, which will not be repeated here.

[0204] In some embodiments, step S2201 and step S2202 may be executed sequentially or one after another, for example, step S2201 may be executed first, and then step S2202; for another example, step S2202 may be executed first, and then step S2201.

[0205] S2203: The terminal device determines that a positioning reference signal resource that meets a set condition among the positioning reference signal resources is a first positioning reference signal resource for carrier aggregation.

[0206] The optional method of step S2203 can refer to the optional method of step S2103 in Figure 2A and other parts of the embodiment involved in Figure 2A, which will not be repeated here.

[0207] S2204: The first positioning reference signal resource conflicts with a first resource occupied by other signals, and at least part of the first positioning reference signal resource is discarded, where the other signals are signals other than the positioning reference signal transmitted on the first positioning reference resource.

[0208] In some implementations, the other signals are signals other than the positioning reference signal transmitted on the first positioning reference resource. Optionally, the other signals may include, but are not limited to, synchronization signals (SS), channel state information reference signals (CSI-RS), demodulation reference signals (DMRS), and tracking reference signals (TRS). In some embodiments, conflicts between the first positioning reference signal resource and the first resource occupied by other signals may include frequency conflicts, time conflicts, and the like.

[0209] Optionally, if the first positioning reference signal resource and the first resource occupied by the other signal use the same frequency bandwidth, it can be understood that the first positioning reference signal resource has a frequency conflict with the first resource occupied by the other signal. Optionally, if the first positioning reference signal resource and the first resource occupied by the other signal use the same time period, it can be understood that the first positioning reference signal resource has a time conflict with the first resource occupied by the other signal.

[0210] In some embodiments, if a first positioning reference signal resource conflicts with a first resource occupied by another signal, the first positioning reference signal resource is discarded. Alternatively, all first positioning reference signal resources on each carrier may be discarded, which may be referred to as a first discard mode in the present disclosure. Partial first positioning reference signal resources on a carrier may be discarded, which may be referred to as a second discard mode in the present disclosure.

[0211] In the embodiment of the present disclosure, FIG3A shows a first discarding mode. When the first positioning reference signal resources conflict with the first resources occupied by other signals, all the first positioning reference signal resources on each carrier are discarded.

[0212] In some embodiments, the first symbol position and the first frequency at which the first resource is located may be determined, and based on the first symbol position and the first frequency, the first positioning reference signal resource on the carrier may be partially discarded.

[0213] In some embodiments, when the first positioning reference signal resource conflicts with the first resource occupied by other signals, the first symbol position of the first resource is determined, and the first positioning reference signal resource at the first symbol position on each carrier is discarded, as shown in FIG3B .

[0214] In some embodiments, when the first positioning reference signal resource conflicts with the first resource occupied by other signals, the first frequency of the first resource is determined, and all first reference signal resources on the carrier of the first frequency are discarded, as shown in FIG3C .

[0215] In some embodiments, when the first positioning reference signal resource conflicts with the first resource occupied by other signals, the first symbol position of the first resource and the first frequency of the first resource are determined, and the first positioning reference signal resource on the carrier at the first frequency in the first symbol position is discarded, as shown in Figure 3D.

[0216] By partially discarding, the terminal device can provide higher flexibility and resource utilization efficiency for the first positioning reference signal resources. In the case of the remaining first positioning reference signal resources, measurement can be performed even if the bit accuracy performance is slightly reduced.

[0217] S2205: The terminal device determines an extension amount for the positioning reference signal measurement duration based on a discarding mode for the first positioning reference signal resource.

[0218] In some implementations, the measurement duration of one or more positioning reference signal measurements may be extended to improve the utilization of the first positioning reference signal resource.

[0219] In some implementations, the durations of measurements of different positioning reference signal resources are extended by the same or different amounts.

[0220] In some implementations, the duration extension amount of the first positioning reference signal resource corresponds to a discarding pattern. The terminal device may determine the duration extension amount of the first positioning reference signal resource based on the discarding pattern of the first positioning reference signal resource.

[0221] In some implementations, if the discard mode is discarding part of the first positioning reference signal resource, the duration extension is determined to be a first extension amount, and if the loss mode is discarding all of the first positioning reference signal resource, the duration extension is determined to be a second extension amount. The first extension amount is smaller than the second extension amount.

[0222] S2206: The terminal device extends the measurement duration of the positioning reference signal according to the duration extension amount.

[0223] In some embodiments, if the terminal device is capable of supporting one of the second discarding modes, the first measurement duration T of the positioning reference signal resource time difference (RSTD) RSTD can be extended according to the first extension amount. RSTD_wo_gap,i The first measurement duration of the positioning reference signal resource time difference (RSTD) is extended, where RSTD is the arrival time difference between two positioning reference signals at the terminal. For example, the first extension amount may be X1. If the terminal device supports the first discard mode, the first measurement duration of the positioning reference signal resource time difference may be extended by a second extension amount, for example, X2. X1 must be less than X2.

[0224] In some embodiments, if the terminal device is capable of supporting one of the second discarding modes, the second measurement time T of the reference signal receiving power (RSRP) of the positioning reference signal can be extended according to the first amount. PRS-RSRP,total For example, the first extension amount may be X3. If the terminal device is capable of supporting the first discard mode, the second measurement duration of the positioning reference signal RSRP may be extended by a second extension amount, for example, the second extension amount may be X4. X3 is smaller than X4.

[0225] In some embodiments, if the terminal device is capable of supporting one of the second discarding modes, the third measurement time length T of the receiving-transmitting time difference of the terminal device can be extended according to the first extension amount. UERxTx,Total The first extension amount may be X5. If the terminal device supports the first discard mode, the third measurement duration of the receive-transmit time difference of the terminal device may be extended by a second extension amount, for example, X6. X5 is smaller than X6.

[0226] In some embodiments, X1, X3, and X5 may be the same or different, and X2, X4, and X6 may be the same or different.

[0227] S2207, the terminal device performs positioning measurement based on the remaining first positioning reference signal resources and reports second information.

[0228] In some implementations, the remaining first positioning reference signal resources can be used to transmit reference signals based on carrier aggregation, that is, the remaining first positioning reference signal resources in the reference signal resource sets on different carriers can be carrier aggregated to transmit reference signals, that is, the network device can aggregate and send PRS or SRS based on the remaining first positioning reference signal resources, and the terminal device can measure the reference signals on the remaining first positioning reference signal resources in the reference signal resource sets of different carriers to obtain a measurement result.

[0229] In some embodiments, the terminal device may perform carrier aggregation based on the remaining first reference signal resources to transmit a reference signal for positioning measurement to obtain a measurement result.

[0230] In some embodiments, the above measurement result may be at least one of the following:

[0231] Reference Signal Time Difference (RSTD);

[0232] Rx-Tx time difference;

[0233] Reference Signal Received Power (RSRP);

[0234] Reference Signal Received Path Power (RSRPP)

[0235] In some embodiments, there may be multiple remaining first positioning reference signals, and one measurement result is obtained for the multiple remaining first positioning reference signal resources.

[0236] For example, assume that the first information configures reference signal resource sets on carrier #a and carrier #b, where the reference signal resource sets on carrier #a are: reference signal resource set #1, reference signal resource set #2, and reference signal resource set #3; and the reference signal resource sets on carrier #b are: reference signal resource set #4 and reference signal resource set #5. The terminal device can determine the first positioning reference signal resources in reference signal resource set #1 and reference signal resource set #4 according to the set conditions in the third information. If the first positioning reference signal resources conflict with the first resources occupied by other signals, the first positioning reference signal resources are discarded. The remaining first positioning reference signal resources in reference signal resource set #1 and reference signal resource set #4 can be used to aggregate and send PRS or SRS. In other words, a measurement result is obtained for the remaining first positioning reference signal resources in the two sets.

[0237] In some embodiments, the terminal device may report the measurement result to the network device based on the second information. In some embodiments, the second information may be, for example, reporting information, measurement reporting information, result reporting information, etc., but is not limited thereto.

[0238] The positioning measurement method involved in the embodiments of the present disclosure may include at least one of steps S2201 to S2207.

[0371] The communication method involved in the embodiment of the present disclosure may include at least one of steps S5201 and S5202. For example, step S5202 may be implemented as an independent embodiment, and steps S5201+S5202 may be implemented as independent embodiments, but are not limited thereto.

[0372] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0373] The following is an exemplary introduction to the above method.

[0374] In the embodiment of the present disclosure, the behavior and performance of the UE may be measured based on PRS with bandwidth aggregation. When the PRS in one PFL conflicts with other signals, the positioning measurement may still be completed.

[0375] The disclosed embodiments are intended to describe procedures for supporting aggregation of PRS / SRS resources across PFLs / carriers (respectively) for positioning measurements, assuming that the signals on the aggregated resources are transmitted and received (respectively) using a single RF chain (same antenna).

[0376] Optional Example 1: To aggregate PRSs in two or three different PFLs for PRS bandwidth, certain conditions must be met for the aggregated PRS resources from the TRP across the aggregated bandwidth or PFLs. For example, RAN4 stipulates that different PFLs must have the same parameters and the same time slot / symbol when aggregated.

[0377] In the previous RAN1 meeting, more PRS transmission parameters were discussed (for example, the same comb value, the same number of PRS resource sets, the same number of PRS resources, the same gNB Tx TEG, the same UE Rx TEG, the same QCL type, power consistency, and the same NR-DL-PRS-SFN0-Offset value in the aggregated PFL were also proposed).

[0378] RAN1#112 protocol:

[0379] To enable PRS bandwidth aggregation of PRS resources from two or three different PFLs, some conditions must be met for the aggregated PRS resources from the TRP across the aggregated bandwidth / PFLs.

[0380] In the same time slot, in the same symbol, from the same RF chain (i.e. the same antenna) through the same TRP associated with the same ARP, this means:

[0381] FFS: Maximum Tx timing error for the same gNB Tx TEG and the same UE Rx TEG;

[0382] Same QCL;

[0383] Same number of symbols, symbol positions in a time slot, repetition factor;

[0384] FFS: same period and slot offset;

[0385] FFS: silent mode;

[0386] Same parameters, i.e. same CP and SCS;

[0387] Same or different bandwidth;

[0388] Same comb value;

[0389] FFS: The same number of PRS resource sets and TRP resources;

[0390] The power of each subcarrier is the same;

[0391] FFS: same NR-DL-PRS-SFN0-Offset;

[0392] The aggregated PFL is configured on the same aligned numerology grid;

[0393] FFS: How to maintain a continuous PRS pattern across the aggregate bandwidth even in the presence of guard tones (e.g., PFL with different RE-offset configurations, PFL with different A-points);

[0394] Phase continuity between aggregated PFLs.

[0395] R1#113 protocol:

[0396] To aggregate PRS bandwidth from two or three different PFLs, the following aggregate PRS resources are required for a TRP:

[0397] Same period and slot offset;

[0398] Same silent mode;

[0399] The same NR-DL-PRS-SFN0-Offset value;

[0400] When a UE wishes to configure PRS resources across the aggregate bandwidth in the frequency domain, it needs to maintain a PRS pattern with even spacing of each symbol (note: this does not exclude the possibility of losing some PFLs in the guard band between two PFLs).

[0401] From the perspective of RAN1, FFS has the same antenna ports.

[0402] Observation 1: In addition to the conclusion of RAN4, some conditions of RAN1 on PRS bandwidth aggregation may affect the requirements of RRM (e.g., same period, same antenna port).

[0403] In our understanding, if there is only a single RSRP / RSTD measurement result report for all aggregated PFLs, in order to avoid overly complex UE implementation, the physical aspects of these aggregated PRSs should be unified. Therefore, we recommend:

[0404] Recommendation 1: RAN4 should define the core requirements for positioning measurements based on PFL bandwidth aggregation, which should at least meet the following conditions:

[0405] In the same time slot, in the same symbol, associated with the same TRP and the same ARP, from the same antenna;

[0406] Same number of symbols, symbol positions in a time slot, repetition factor,

[0407] Same period and slot shift;

[0408] Same silent mode;

[0409] Same parameters, i.e. same CP and SCS;

[0410] Same or different bandwidth;

[0411] Same comb value;

[0412] The same number of PRS resource sets and TRP resources;

[0413] The power of each subcarrier is the same.

[0414] Example 2: Conflict handling in bandwidth aggregation

[0415] At the last RAN1 meeting, the following agreement was reached:

[0416] R1#114 protocol:

[0417] In one case, when a PRS resource in one of the aggregated PFLs is discarded due to collision with other signals, for LMF-based positioning, the UE performs positioning measurements based on one or more PRS resources in the aggregated PFL.

[0418] Note: Whether to define performance requirements in case of conflict with other signals is determined by RAN4.

[0419] In principle, there are several UE implementation scenarios when the PRSs in an aggregated PFL are dropped along with other signals.

[0420] Option 1: Discard positioning measurements in the aggregated PFL throughout the PRS occasion.

[0421] Option 2a: Only discard positioning measurements in those aggregated PFLs within the colliding PRS symbols.

[0422] Option 2b: In the entire PRS scenario, the positioning measurements in the conflicting PFL are discarded, and the PRS measurement results can rely on other PFLs.

[0423] Option 2c: Remove positioning measurements in the colliding PFL only within the colliding PRS symbols.

[0424] From a RAN4 RRM perspective, the requirements may be completely different using different UE implementations. In our opinion, option 1 is the most ideal from a RAN4 requirements perspective compared to the other options, as it is an implementation without any UE complexity increase.

[0425] On the other hand, UEs that can implement other methods can provide greater flexibility and PRS resource utilization efficiency. In the case of the remaining PRS resources, measurements can be performed even if the accuracy performance is slightly reduced.

[0426] Option 1 can be seen in FIG3A , Option 2a can be seen in FIG3B , Option 2b can be seen in FIG3C , and Option 2c can be seen in FIG3D .
