Abstract
Description
[Technical Field]
[0001] FIELD Embodiments of the present disclosure relate generally to the field of telecommunications, and more particularly to devices, methods, apparatus, and computer-readable storage media for positioning. [Background technology]
[0002] New Radio (NR) systems provide positioning support. In the Release 18 NR Study Item Description (SID), positioning enhancements include positioning support for Reduced Capability (RedCap) devices, which include several receive radio frequency (RF) chains and have reduced bandwidth support and reduced complexity.
[0003] In the Release 17 NR work item, the maximum bandwidth considered for RedCap devices was 20 MHz for FR1, but it is 5 MHz for Release 18. The Third Generation Partnership Project (3GPP) evaluates performance assuming 100 MHz for FR1, but performance may be worse in narrowband systems due to low sampling rates. Furthermore, 3GPP considers that RedCap devices may be equipped with only a single antenna as a baseline.
[0004] While RedCap devices may support NR positioning functionality, gaps exist in that core and performance requirements are not specified for the positioning-related measurements performed by RedCap devices, and no evaluation has been performed to determine how the reduced capabilities of RedCap devices affect the final location accuracy. It would be desirable to support positioning for reduced-capability (RedCap) terminal devices with reduced bandwidth and a reduced number of receive RF chains.

[0028] 1 illustrates an exemplary communication network 100 in which embodiments of the present disclosure may be implemented. Network 100 may include a first device 110, second devices 120-1 and 120-2, and a third device 130, which may communicate with each other. Hereinafter, for brevity, second devices 120-1 and 120-2 may be referred to collectively as second device 120 or individually as second device 120.
[0029] In some embodiments, some of the first device 110, the second device 120, and the third device 130 may be implemented as terminal devices, and others may be implemented as network devices. In such embodiments, for example, the first device 110 may be implemented as a terminal device for a radio access network. For example, the first device 110 may be implemented as a Reduced Capability (RedCap) device. In such embodiments, the second device 120 may be implemented as a network device for the radio access network, and the third device 130 may be implemented as a network device for the radio access network or for the core network. For example, the second device 120 may be implemented as a gNB, and the third device 130 may be implemented as a Location Management Function (LMF) entity. The LMF entity may be implemented in the radio access network or in the core network.
[0030] In such an embodiment, the second device 120-1 may be serving the first device 110, and the second device 120-2 may not be serving the first device 110. In such an embodiment, the second device 120-1 may be referred to as a serving network device, and the second device 120-2 may be referred to as a neighbor network device.
[0031] Additionally, in such an embodiment, each of second devices 120-1 and 120-2 may be implemented as a transmit receive point (TRP).
[0032] In other embodiments, each of the first device 110, the second device 120, and the third device 130 may be implemented as a terminal device. In such embodiments, the first device 110, the second device 120, and the third device 130 may communicate with each other via a sidelink therebetween.
[0033] It should be understood that the number of network devices and terminal devices is for illustrative purposes only, without implying any limitation. Network 100 may include any suitable number of network devices and terminal devices adapted to implement embodiments of the present disclosure. Although not shown, it should be understood that one or more terminal devices may be served by second device 120. In addition, it should be understood that there may be more neighboring network devices near the terminal device.
[0034] Communications within communication network 100 may occur according to any suitable communication protocol, including, but not limited to, first generation (1G), second generation (2G), third generation (3G), fourth generation (4G), and fifth generation (5G) and the like cellular communication protocols, wireless local network communication protocols such as Institute for Electrical and Electronics Engineers (IEEE) 802.11 and the like, and / or any other protocol now known or to be developed in the future. Further, the communications may utilize any suitable wireless communications technology, including, but not limited to, Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Frequency Division Duplex (FDD), Time Division Duplex (TDD), Multiple-Input Multiple-Output (MIMO), Orthogonal Frequency Division Multiple (OFDM), Discrete Fourier Transform spread OFDM (DFT-s-OFDM), and / or any other technology now known or to be developed in the future.
[0035] In some embodiments, multi-cell round trip time (multi-RTT) positioning of the first device 110 may be performed within the network 100.
[0036] 2 illustrates an example of multi-RTT positioning according to some exemplary embodiments of the present disclosure. As shown in FIG. 2, for purposes of multi-RTT positioning, the second device 120-1 transmits a second reference signal (RS) to the first device 110 and records the time (represented by t0) at which it transmitted the second RS. Upon receiving the second RS from the second device 120-1, the first device 110 records the time (represented by t1) at which it received the second RS.
[0037] The first device 110 may transmit a first RS to the second device 120-1 and record the time (represented by t2) at which it transmitted the first RS. Upon receiving the first RS from the first device 110, the second device 120-1 may record the time (represented by t3) at which it received the first RS. The second device 120-1 may then determine a first time difference between t3 and t0, i.e., t3 - t0.
[0038] In some embodiments, first device 110 may determine a second time difference between t2 and t1 (ie, t2-t1) and transmit the second time difference to second device 120-1.
[0039] Upon receiving the second time difference (t2-t1), the third device 130 may determine a first RTT between the second device 120-1 and the first device 110 based on the first time difference and the second time difference. For example, the second device 120-1 may report the first time difference (t3-t0) to the third device, and the first device may report the second time difference (t2-t1). Based on the provided measurement information, the third device determines that the first RTT is the difference between the first time difference and the second time difference, i.e., (t3-t0)-(t2-t1).
[0040] Similarly, the third device 130 may determine a second RTT between the second device 120-2 and the first device 110.
[0041] In some embodiments, second device 120-1 and second device 120-2 may each transmit an Rx-Tx time difference measurement to third device 130. Alternatively, first device 110 and second device 120 may transmit their respective time differences directly to third device 130, which may determine their respective RTTs. Third device 130 may then determine the location of first device 110 based on the first RTT and second RTT.
[0042] Alternatively, the second device 120-2 may transmit the second RTT to the second device 120-1, and the second device 120-1 may determine the location of the first device 110 based on the first RTT and the second RTT.
[0043] In some embodiments, the first RS may include, but is not limited to, a sounding reference signal (SRS), and the second RS may include, but is not limited to, a positioning reference signal (PRS). The first RS may include a sidelink positioning reference signal. The sidelink positioning reference signal may include an RS transmitted from one UE to another UE for positioning purposes. Hereinafter, embodiments of the present disclosure will be described by taking SRS and PRS as examples. However, other types of reference signals may be applied to embodiments of the present disclosure.
[0044] Frequency bandwidth resources are an important factor for positioning accuracy for both downlink (DL) and uplink (UL) positioning, especially for TDOA (Time Difference Of Arrival) and Multi-RTT positioning technologies because they use timing measurements. To overcome performance degradation from narrow bandwidth resources, frequency hopping for at least one of the first RS and the second RS may be applied to increase the effective bandwidth for positioning while maintaining the instantaneous bandwidth within a maximum bandwidth, such as the RedCap maximum bandwidth. For example, the RedCap maximum bandwidth may be 20 MHz for FR1 and 100 MHz for FR2. In this manner, at least one of the first RS and the second RS may be transmitted each time with a narrow SRS bandwidth, enabling coherent processing across multiple frequency hops at the second device 120.
[0045] 3 illustrates an example 300 of frequency hopping for SRS in accordance with some exemplary embodiments of the present disclosure. In example 300, each of frequency hops 310, 320, and 330 consists of a single SRS resource. In this regard, frequency hops 310, 320, and 330 may be referred to as SRS resources 310, 320, and 330.
[0046] 3, the first device 110 transmits an SRS at each of successive frequency hops 310, 320, and 330. For example, the first device 110 transmits an SRS at each of transmission opportunities 312, 322, and 332. The first RS may include an SRS for positioning or an SRS for MIMO. Hereinafter, the transmission opportunity may also be referred to as a time opportunity. In other words, in example 300, the first RS may be a single SRS.
[0047] A single SRS frequency hop may be defined within a single UL BWP, for example, the bandwidth of a single UL BWP may be 20 MHz.
[0048] The first device 110 may transmit each of the three SRSs in a respective UL bandwidth part (BWP). That is, the three SRSs are transmitted over three different uplink BWPs. To transmit the three SRSs at different frequency hops, the first device 110 may need to perform BWP switching. Thus, there is a time gap for RF switching between transmission opportunity 312 and transmission opportunity 322, and there is a time gap for RF switching between transmission opportunity 322 and transmission opportunity 332.
[0049] The second device 120 receives the three SRSs at frequency hops 310, 320, and 330, stitches the three SRSs together, and performs coherent processing to extract a single positioning measurement from the wideband SRS 340.
[0050] However, in example 300, if first device 110 misses the opportunity to transmit SRS in frequency hop 320 but transmits SRS in each of frequency hops 310 and 330, second device 120 will not be able to perform coherent processing.
[0051] Based on Release 16 and Release 17 NR positioning, it is feasible for the first device 110 to drop an SRS transmission when there is a collision between a Physical Uplink Shared Channel (PUSCH) transmission and an SRS transmission. TS38.214 specifies that "For operation on the same carrier, if the SRS configured by the higher-level parameter SRS-PosResource collides with a scheduled PUSCH, the SRS shall be dropped in the symbol where the collision occurs."
[0052] In the case of SRS frequency hopping, missed opportunities to transmit SRS in a particular SRS frequency hop should be addressed.
[0053] 4 illustrates an example 400 of frequency hopping for SRS in accordance with some exemplary embodiments of the present disclosure. In example 400, all configured frequency hops 410, 420, and 430 consist of a single SRS resource 405. In this regard, each of frequency hops 410, 420, and 430 may be referred to as a portion of the single SRS resource 405 or a repetition of the single SRS resource 405.
[0054] In example 400, the SRS resource configuration may include a repetition number for inter-slot and / or intra-slot repetition. For example, the first device 110 may be configured with SRS resource 405, and the configured repetition number is three. In each of repetitions 410, 420, and 430 (i.e., in each transmission opportunity), the first device 110 transmits a portion of the SRS, although it may be up to the first device 110 as to which portion it should transmit. In other words, in example 400, the first RS may be a "piece" or "segment" of the SRS. It should be understood that from a receiver's perspective, all the pieces or segments of the SRS may be considered a single SRS after they are combined.
[0055] The difference between example 300 and example 400 is that in example 300, second device 120 configures which SRS frequency hops should be transmitted in each SRS transmission opportunity, so that second device 120 can avoid unnecessary frequency resource allocation. Example 400 requires reserving unnecessary frequency resources, but the configuration method may be simpler.
[0056] To solve the above and other potential problems, embodiments of the present disclosure provide a solution for positioning. In this solution, a first device receives, from a second device for a radio access network, a priority configuration for transmission of a first RS for positioning the first device at a frequency hop. The priority configuration indicates a first priority for transmission of the first RS at the frequency hop and a second priority for one or more transmissions other than the transmission of the first RS at a time opportunity associated with the frequency hop. The first device determines, based at least on the priority configuration, whether the first priority for transmission of the first RS is higher than the second priority. If the first priority is higher than the second priority, the first device transmits the first RS at the frequency hop. In this manner, transmission of the first RS at a time opportunity can be ensured. Therefore, missing an opportunity to transmit the first RS at a specific frequency hop can be avoided.
[0057] Hereinafter, some embodiments of the present disclosure according to a first aspect will be described with reference to FIGS.
[0058] 5 illustrates a signaling chart illustrating a process 500 for positioning according to some exemplary embodiments of the present disclosure. For purposes of discussion, process 500 will be described with reference to FIG. 1. Process 500 may involve first device 110 and second device 120 in FIG. 1.
[0059] 5, the second device 120 determines 510 a priority configuration for transmission of the first RS for positioning the first device 110 at a frequency hop. The priority configuration indicates a first priority for transmission of the first RS at a frequency hop and a second priority for one or more transmissions other than the transmission of the first RS at a time opportunity associated with the frequency hop.
[0060] In some embodiments, the one or more transmissions other than the transmission of the first RS include a transmission of at least one of a PUSCH, a Physical Uplink Control Channel (PUCCH), a Physical Random Access Channel (PRACH), or a reference signal other than the first RS.
[0061] The second device 120 transmits 520 the priority configuration to the first device 110 .
[0062] Upon receiving the priority configuration from the second device 120, the first device 110 determines 530 whether the first priority of the transmission of the first RS is higher than the second priority based on at least the priority configuration, and based on the determination that the first priority is higher than the second priority, the first device 110 transmits 540 the first RS in a frequency hop.
[0063] For example, the first device 110 may determine that the first priority is higher than the second priority by comparing the first priority with the second priority. In an example, the first device 110 refrains from (i.e., does not transmit) the first RS in the frequency hop based on determining that the first priority is lower than the second priority. In such a case, the first device 110 may transmit some other transmission, such as a PUSCH transmission, instead.
[0064] In the process 500, if the first priority of the transmission of the first RS is higher than the second priority of one or more transmissions other than the transmission of the first RS at the time opportunity associated with the frequency hop, the first device 110 transmits the first RS at the frequency hop 540. In this manner, the transmission of the first RS at the time opportunity can be ensured. Thus, missing the opportunity to transmit the first RS at a particular frequency hop can be avoided.
[0065] In some embodiments, the first RS may be a single SRS, as described with reference to Figure 3. Alternatively, the first RS may be a "fragment" or "segment" of an SRS, as described with reference to Figure 4.
[0066] In some embodiments, the second device 120 may not successfully receive the first RS or acquire positioning measurements for the first RS at a particular frequency hop. In such embodiments, the second device 120 may send a request 550 to the first device 110 for retransmission of the first RS using the dedicated frequency hop.
[0067] Upon receiving the request, the first device 110 may retransmit 560 the first RS to the second device 120 using dedicated frequency hops.
[0068] In some embodiments, the first RS may include, but is not limited to, an SRS. Hereinafter, embodiments of the present disclosure will be described by taking an SRS as an example. However, other types of reference signals may be applied to embodiments of the present disclosure.
[0069] In some embodiments, the second device 120 transmits configuration information associated with the first RS to the first device 110. The configuration information may indicate multiple consecutive frequency hops within the periodicity of the SRS resource for transmission of the SRS. Hereinafter, the number of multiple consecutive frequency hops within the periodicity of the SRS resource is denoted as M.
[0070] In some embodiments, the priority configuration may include a first number of consecutive frequency hops for transmission of the first RS. Hereinafter, the first number is denoted as K, where 1 <K≦Mである。
[0071] In some embodiments, the first number (K) is associated with a first positioning capability of the first device 110. For example, the first positioning capability may be a desired positioning capability. For example, the desired positioning capability may be a horizontal positioning accuracy of less than 1 meter. To achieve this positioning capability, at least four frequency hops may be required, with 20 MHz for each frequency hop. The first device may be configured with K=4.
[0072] In some embodiments, the first device 110 may determine that a first priority for transmission of the first RS in a first number (K) of consecutive frequency hops is higher than a second priority for transmission of other channels or signals. In other words, the first device 110 may place a higher priority on transmission of the first RS in the first number (K) of consecutive frequency hops. Until the first device 110 transmits the first RS from the first number (K) of consecutive frequency hops, the first device 110 does not drop any transmission of the first RS, even if there is a PUSCH scheduled on an Orthogonal Frequency Division Multiplexing (OFDM) symbol configured with at least one resource for the first RS.
[0073] In some embodiments, the first device 110 may determine that a first priority of transmission of the first RS in a first number (K) of consecutive frequency hops is lower than a second priority. If transmission of the first RS is not performed in at least one of the first number (K) of consecutive frequency hops, the first device 110 may determine not to perform transmission of the first RS in the remaining consecutive frequency hops of the first number (K) of consecutive frequency hops.
[0074] In such an embodiment, while the first device 110 transmits the first RS, the first device 110 follows the legacy rule such that PUSCH transmission has higher priority than the transmission of the first RS. However, if the first device 110 determines that it cannot transmit the first RS in at least one of the first number (K) consecutive frequency hops, it drops the transmission of the remaining part of the first RS in the remaining frequency hops. Alternatively, the first device 110 may assume that the transmission of the first RS has lower priority for the remainder of the frequency hops, even if some of the remainder of the frequency hops do not include a PUSCH (or other high-priority channel and reference signal) on the same symbol.
[0075] In some embodiments, the priority configuration may include a second number of consecutive frequency hops for transmission of the first RS. Hereinafter, the second number is represented as L, where L is the number of hops in a given frequency range. <L<Kである。
[0076] In some embodiments, the second number (L) is associated with a second positioning performance of the first device 110. The second positioning performance is lower than the first positioning performance. For example, the second positioning performance may be a minimum positioning performance. For example, the minimum positioning performance may be a horizontal positioning accuracy of less than 3 m. To achieve this positioning performance, at least two frequency hops may be required, with each frequency hop being 20 MHz. The first device may be configured with K=2.
[0077] In some embodiments, the first device 110 may determine that a first priority of transmission of the first RS in a second number (L) of consecutive frequency hops is lower than a second priority. If transmission of the first RS is successful in the second number (L) of consecutive frequency hops, the first device 110 may determine that a first priority of transmission of the first RS in a fourth number of consecutive frequency hops is higher than a second priority.
[0078] In some embodiments, the priority configuration includes a first number and a second number, and a fourth number is equal to the difference between the first number (K) and the second number (L), i.e., K - L.
[0079] For example, assume that N represents the number of first RSs transmitted in consecutive frequency hops. When 1 < N <= L, the legacy priority rule is applied for the transmission of the first RS and PUSCH. That is, the transmission of the first RS has a lower priority than the PUSCH transmission. When L < N <= K, the transmission of the first RS has a higher priority than the PUSCH transmission.
[0080] Alternatively, in some embodiments, the fourth number is equal to the difference between the number of time opportunities (M) associated with the transmission of the first RS and the second number (L). For example, the number of time opportunities associated with the transmission of the first RS can be the number of consecutive frequency hops within the periodicity of the SRS resource.
[0081] In such embodiments, the first device 110 may follow the legacy priority rule while transmitting the first RS from the second number (L) of consecutive frequency hops. That is, the first device 110 transmits the first RS in L consecutive frequency hops in accordance with the legacy rule (i.e., PUSCH has a higher priority than the first RS). If the first device 110 successfully transmits the first RS in the second number (L) of consecutive frequency hops, the first device 110 places a higher priority on the transmission of the first RS for the remaining (K - L) frequency hops. Such embodiments can ensure the transmission of the first RS in the first number (K) of consecutive frequency hops to support the first positioning performance (such as the desired positioning performance).
[0082] Alternatively, in some embodiments, the first device 110 may determine that the first priority of transmitting the first RS in the second number (L) of consecutive frequency hops is higher than the second priority. If the transmission of the first RS is successfully performed in the second number (L) of consecutive frequency hops, the first device 110 may determine that the first priority of transmitting the first RS in the fourth number of consecutive frequency hops is lower than the second priority. The fourth number is equal to the difference between the first number (K) and the second number (L), i.e., K - L.
[0083] For example, assume that N represents the number of the first RS transmitted in consecutive frequency hops. If 1 < N <= L, the high priority is applied for transmitting the first RS, and the low priority is applied for PUSCH transmission. If L < N <= K, the lower priority is applied for transmitting the first RS, and the high priority is applied for PUSCH transmission.
[0084] In such embodiments, after the first device 110 successfully transmits the first RS in the second number (L) of consecutive frequency hops, the first device 110 reduces the priority of transmitting the first RS for the remaining (K - L) frequency hops. That is, such embodiments guarantee the transmission of the first RS in at least the second number (L) of consecutive frequency hops.
[0085] [[ID=!12]]As described above, in some embodiments, the multi-RTT positioning of the first device 110 may be performed within the network 100.
[0086] In embodiments where the multi-RTT positioning of the first device 110 is performed, the first device 110 may first receive the second RS from the second device 120 and then transmit the first RS to the second device 120, as shown in FIG. 2. In such embodiments, the first device 110 may determine the first priority of transmitting the first RS based on the reception and measurement of the second RS.
[0087] It should be noted that there seems to be a small error in the original text where "上に説明されたように" in line 12 is translated as "As described above" in the current translation, but in the original text, there is an exclamation mark (!) in front of the sentence which is not reflected in the translation. You may want to double-check this with the original source for accuracy.In some embodiments, the priority configuration may include a third number of consecutive frequency hops for reception of the second RS from the second device 120. Hereinafter, the third number is represented as Z, where Z>1.
[0088] In some embodiments, if the second RS is successfully received in a fifth number of consecutive frequency hops and positioning measurements of the second RS are successfully performed in the fifth number of consecutive frequency hops, the first device 110 may determine that the first priority of the transmission of the first RS is higher than the second priority of the transmission of other channels or signals.
[0089] In some embodiments, the fifth number is received from the second device 120 .
[0090] In some embodiments, the positioning measurements may include at least one of: timing measurements, carrier phase measurements, Reference Signal Receiving Power (RSRP), Reference Signal Receiving Power per signal path (RSRPP), or Reference Signal Receiving Quality (RSRQ).
[0091] In some embodiments, the fifth number may be greater than the third number (Z). For example, the fifth number may be equal to the total number of consecutive frequency hops configured for receiving the second RS from the second device 120. In such an embodiment, if the first device 110 successfully receives all configured PRSs in the fifth number of frequency hops and if the first device 110 successfully measures positioning measurements from the PRSs from the frequency hops, the first device 110 places a high priority on transmitting the SRS in the frequency hops. Note that a high priority on transmitting the SRS in the frequency hops means that the first device 110 transmits the SRS in the frequency hops, although the PUSCH is scheduled on the symbols in which the SRS frequency hops are configured.
[0092] In other embodiments, the fifth number may be equal to the third number (Z). In such embodiments, once the first device 110 successfully receives the third number (Z) of PRSs at the frequency hops required to provide a particular level of performance and the first device 110 successfully measures positioning measurements from the third number (Z) of PRSs at the frequency hops, the first device 110 ignores the legacy behavior of higher priority for PUSCH transmissions and places higher priority on the transmission of SRS at the frequency hops. Note that higher priority for the transmission of SRS at the frequency hops means that the PUSCH is scheduled on the symbols where the SRS frequency hops are configured, but the first device 110 transmits the SRS at the frequency hops.
[0093] In some embodiments, the first device 110 may determine not to transmit the first RS in a frequency hop. In such embodiments, if the first device 110 determines that the second RS is not successfully received in at least one of the third number (Z) consecutive frequency hops and that positioning measurements of the second RS are not successfully performed in at least one of the third number (Z) consecutive frequency hops, the first device 110 may determine not to transmit the first RS in a frequency hop.
[0094] In such an embodiment, if the first device 110 does not successfully receive a PRS at a frequency hop required to provide a particular level of performance, and if the first device 110 does not successfully measure positioning measurements from the PRS at a frequency hop, the first device 110 drops the transmission of the SRS at the frequency hop. Additionally, the first device 110 may report to the third device 130 that it failed to acquire positioning measurements.
[0095] In an embodiment in which multi-RTT positioning of the first device 110 is performed, the first device 110 may first transmit a first RS to the second device 120 and then receive a second RS from the second device 120. In such an embodiment, the first device 110 may determine a third priority for measuring the second RS received from the second device 120.
[0096] In some embodiments, if the first RS is successfully transmitted in the sixth number of consecutive frequency hops, the first device 110 may determine that the third priority of measuring the second RS is higher than the fourth priority for receiving or processing channels or signals other than the second RS.
[0097] In some embodiments, the sixth number is received from the second device 120 .
[0098] In some embodiments, the at least one channel or at least one signal other than the second RS may include, but is not limited to, a Physical Downlink Shared Channel (PDSCH) or a reference signal other than a PRS.
[0099] In some embodiments, the sixth number may be greater than the first number (K). For example, the sixth number may be equal to the number (M) of consecutive frequency hops in the SRS resource periodicity. In such an embodiment, if the first device 110 successfully transmits all configured SRSs at M frequency hops, the first device 110 places a higher priority on measuring PRSs at frequency hops within the PRS processing window. That is, if the PRS measurement priority is configured as "low," the first device 110 places a higher priority on PRS measurements by ignoring the configured priority.
[0100] In some embodiments, the sixth number may be equal to the first number (K). In such embodiments, once the first device 110 successfully transmits the sixth number of SRSs at a frequency hop required to provide a particular level of performance, the first device 110 places a higher priority on measuring PRSs at the frequency hop. That is, if the priority of PRS measurements is configured as "low," the first device 110 places a higher priority on PRS measurements by ignoring the configured priority.
[0101] In some embodiments, if the first RS is not successfully transmitted in at least one of the seventh number of consecutive frequency hops, the first device 110 may determine that the third priority of measuring the second RS is lower than the fourth priority for receiving or processing channels or signals other than the second RS. In such embodiments, if the first device 110 does not successfully transmit an SRS in a frequency hop required to provide a particular level of performance, and if the first device 110 does not successfully measure positioning measurements from a PRS in a frequency hop, the first device 110 places a lower priority on PRS measurements within the PRS processing window.
[0102] 6 illustrates a signaling chart illustrating a process 600 for positioning according to some exemplary embodiments of the present disclosure. Process 600 may be considered an exemplary implementation of process 500. For purposes of discussion, process 600 will be described with reference to FIG. 1. Process 600 may involve first device 110, second device 120, and third device 130 in FIG. 1.
[0103] In process 600, second device 120-1 may be serving first device 110, and second device 120-2 may not be serving first device 110. In such an embodiment, second device 120-1 may be referred to as a serving network device, and second device 120-2 may be referred to as a neighboring network device.
[0104] Actions 510, 520, 530, and 540 in process 600 are the same as those in process 500. Details of these actions are omitted for brevity.
[0105] Process 600 differs from process 500 in actions 610 , 615 , 620 , 625 , 630 , 635 , 640 , 645 , and 650 .
[0106] Specifically, the first device 110 transmits capability information to the second device 120-1 610. The capability information may indicate that the first device 110 is a normal UE or a RedCap UE.
[0107] Upon receiving the capability information, second device 120-1 may transmit 615 the capability information to third device 130. Alternatively, first device 110 may transmit the capability information directly to third device 130.
[0108] The second device 120-1 transmits 620 configuration information associated with the first RS to the first device 110. The configuration information may include at least one of: an identifier (ID) of a resource for transmission of the first RS, or an ID of a frequency hop for transmission of the first RS.
[0109] For example, the configuration information may indicate multiple SRS resources across multiple UL BWPs within the SRS resource periodicity, as shown in Figure 3. In another example, the configuration information may indicate multiple repetitions of a single SRS resource across multiple UL BWPs within the SRS resource periodicity, as shown in Figure 4.
[0110] The second device 120-1 transmits 625 configuration information associated with the first RS to the second device 120-2. The configuration information may include information regarding which frequency hop is used at each transmission opportunity for the first RS. This information helps the second device 120-2 (such as a neighboring gNB) measure the first RS at the frequency hop and perform aggregation operations.
[0111] The second device 120-1 transmits 630 the configuration information associated with the first RS to the third device 130.
[0112] In some embodiments, the first device 110 may transmit the first RS in a frequency hop at a different transmit opportunity than the configured transmit opportunity, as described with reference to FIG.
[0113] FIG. 7 illustrates an example 700 of frequency hopping for SRS, in accordance with some exemplary embodiments of the present disclosure.
[0114] Example 700 is similar to example 400. Example 700 differs from example 400 in that, in example 700, the first device 110 transmits a first portion of the SRS at the frequency hop 410 at the first time opportunity 710, but the first device 110 fails to transmit a second portion of the SRS at the frequency hop 420 at the second time opportunity 720. The first device 110 then places a high priority on transmitting the second portion of the SRS. That is, as shown in FIG. 7 , although the third portion of the SRS is to be transmitted at the third time opportunity 730, if the first device 110 fails to transmit the second portion of the SRS at the frequency hop 420 at the second time opportunity 720, the first device 110 must attempt to transmit the second portion of the SRS at the frequency hop 430 or at the frequency hop 740 at the third time opportunity 730.
[0115] Returning to Figure 6, in an embodiment in which the first device 110 was transmitting the first RS in a frequency hop at a different transmit opportunity than the configured transmit opportunity, the first device 110 may transmit information regarding the resource used for transmission of the first RS to the second device 120-1 635. For example, the information regarding the resource may include at least one of: an SRS resource ID, a frequency hop ID associated with the SRS resource ID, or a transmission opportunity index associated with the SRS resource ID.
[0116] Then, as the second device 120-2 receives and measures the first SRS, the second device 120-1 may transmit 640 to the second device 120-2 information regarding the resources used for transmitting the first RS.
[0117] Upon receiving and measuring the first SRS, the second device 120-1 transmits 645 positioning measurements to the third device.
[0118] Similarly, upon receiving and measuring the first SRS, the second device 120-2 transmits 650 positioning measurements to the third device 130.
[0119] 8 shows a flowchart of an example method 800 performed at a first device, according to some example embodiments of the present disclosure. For purposes of discussion, the method 800 will be described from the perspective of the first device 110 with respect to FIG.
[0120] In block 810, the first device receives, from a second device for a wireless access network, a priority configuration for transmission of a first RS for positioning the first device at a frequency hop, the priority configuration indicating a first priority for transmission of the first RS at the frequency hop and a second priority for one or more transmissions other than the transmission of the first RS at a time opportunity associated with the frequency hop.

[0138] In some embodiments, the fifth number is greater than or equal to the third number (Z).
[0139] In some embodiments, the first device determines not to transmit the first RS in a frequency hop by determining that the second RS is not successfully received in at least one of a third number (Z) of consecutive frequency hops or that positioning measurements of the second RS are not successfully performed in at least one of a third number (Z) of consecutive frequency hops.
