[0001] Technical field This disclosure relates to wireless communications, including but not limited to systems and methods for positioning. [Background technology]

[0002] background The Third Generation Partnership Project (3GPP®), a standards organization, is currently working on defining a new radio interface called 5G New Radio (5G NR), as well as the Next Generation Packet Core Network (NG-CN or NGC). 5G NR has three main components: the 5G Access Network (5G-AN), the 5G Core Network (5GC), and the User Equipment (UE). To facilitate the use of different data services and requirements, the elements of the 5GC, also called network functions, have been simplified; some are software-based, some are hardware-based, and as a result, they can be adapted as needed.

[0032] For example, BS102 may operate within the allocated channel transmission bandwidth to provide sufficient coverage to UE104. BS102 and UE104 may communicate via downlink radio frames 118 and uplink radio frames 124, respectively. Each radio frame 118 / 124 may be further divided into subframes 120 / 127, which may contain data symbols 122 / 128. In this disclosure, BS102 and UE104 are described herein as non-limiting examples of “communication nodes” that can generally implement the methods disclosed herein. Such communication nodes may be capable of wireless and / or wired communication according to various embodiments of the present solution.

[0033] Figure 2 shows a block diagram of an exemplary wireless communication system 200 for sending and receiving wireless communication signals (e.g., OFDM / OFDMA signals) according to some embodiments of the present solution. The system 200 may include components and elements configured to support known or conventional operating features not necessarily described in detail herein. In one exemplary embodiment, the system 200 may be used to communicate (e.g., send and receive) data symbols in a wireless communication environment such as the wireless communication environment 100 in Figure 1, as described above.

[0034] System 200 generally includes a base station 202 (hereinafter, "BS202") and a user equipment device 204 (hereinafter, "UE204"). BS202 includes a BS (base station) transceiver module 210, a BS antenna 212, a BS processor module 214, a BS memory module 216, and a network communication module 218, each module being coupled and interconnected to one another as needed via a data communication bus 220. UE204 includes a UE (user equipment) transceiver module 230, a UE antenna 232, a UE memory module 234, and a UE processor module 236, each module being coupled and interconnected to one another as needed via a data communication bus 240.

[0036] According to some embodiments, the UE transceiver 230 may be referred herein as an “uplink” transceiver 230, comprising a radio frequency (RF) transmitter and an RF receiver, each having a circuit coupled to the antenna 232.

Similarly, according to some embodiments, the BS transceiver 210 may be referred herein as a “downlink” transceiver 210, comprising an RF transmitter and an RF receiver, each having a circuit coupled to the antenna 212. Alternatively, a downlink duplex switch may couple the downlink transmitter or receiver to the downlink antenna 212 in a time-duplex manner. The operation of the two transceiver modules 210 and 230 may be coordinated in time so that the downlink transmitter is coupled to the downlink antenna 212 and the uplink receiver circuit is coupled to the uplink antenna 232 for receiving transmissions over the wireless transmission link 250. Conversely, the operation of the two transceivers 210 and 230 can be coordinated in time so that the uplink transmitter is coupled to the uplink antenna 232 and the downlink receiver is coupled to the downlink antenna 212 for receiving transmissions over the wireless transmission link 250. In some embodiments, there is tight time synchronization with a minimum guard time between changes in duplex direction.

[0037] The UE transceiver 230 and base station transceiver 210 are configured to communicate via a wireless data communication link 250 and to cooperate with appropriately configured RF antenna equipment 212 / 232 capable of supporting specific wireless communication protocols and modulation schemes. In some exemplary embodiments, the UE transceiver 210 and base station transceiver 210 are configured to support industry standards such as Long-Term Evolution (LTE) and emerging 5G standards.

[0039] Furthermore, steps of methods or algorithms described in relation to embodiments disclosed herein can be directly embodied in hardware, firmware, software modules executed by processor modules 214 and 236, respectively, or in any practical combination thereof. Memory modules 216 and 234 can be implemented as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disks, removable disks, CD-ROMs, or any other form of storage medium known in the art. In this regard, memory modules 216 and 234 can be coupled to processor modules 210 and 230, respectively, so that processor modules 210 and 230 can read information from and write information to memory modules 216 and 234, respectively. Memory modules 216 and 234 can also be integrated into their respective processor modules 210 and 230. In some embodiments, memory modules 216 and 234 may each include cache memory for storing temporary variables or other intermediate information during the execution of instructions to be executed by processor modules 210 and 230. Memory modules 216 and 234 may also each include non-volatile memory for storing instructions to be executed by processor modules 210 and 230.

[0040] The network communication module 218 generally represents hardware, software, firmware, processing logic, and / or other components of the base station 202 that enable bidirectional communication between the base station transceiver 210 and other network components and communication nodes configured to communicate with the base station 202. For example, the network communication module 218 may be configured to support Internet or WiMAX traffic. In a typical deployment, but not limited to, the network communication module 218 provides an 802.3 Ethernet® interface so that the base station transceiver 210 can communicate with a conventional Ethernet®-based computer network. In this way, the network communication module 218 may include a physical interface for connecting to a computer network (e.g., a mobile switching center (MSC)).

Systems and methods for positioning

[0043] In timing-based positioning methods, positioning accuracy is highly dependent on the PRS bandwidth. However, in the case of a reduced-capacity (RedCap) UE, the maximum supported bandwidth is limited; for example, a RedCap UE may only support 20 MHz in FR1 and 100 MHz in FR2. However, PRSs specified in current specifications may be configured with larger transmission bandwidths to achieve high positioning accuracy. Methods to improve the positioning accuracy of this type of UE while maintaining low cost may be investigated. Several solutions have been proposed to support PRS frequency hopping with K PRBs that overlap between adjacent frequency hops for PRSs of comparable wide bandwidth, mitigating the effects of phase noise. However, in the positioning process, a RedCap UE may require extra switching time to sound or monitor the PRS at different hops. Therefore, the corresponding UE capability along with the measurement period may be utilized for the RedCap UE.

[0044] Several parameters (such as the inter-slot repetition factor) for PRS reception can be supported. For example, dl-PRS-ResourceRepetitionFactor defines how many times each DL-PRS resource is repeated for a single instance of the DL-PRS resource set, and takes the value

Chem.

[0045] The concept of RedCap UE can be proposed to meet the requirements of specific application scenarios by reducing terminal air interface capacity, reducing complexity, and achieving requirements such as cost reduction and power consumption reduction. In the positioning agenda item, it can be assumed that RedCap UE sounds PRS at different hops. As shown in Figure 3, the transmitted PRS may have a wide bandwidth (e.g., 100Mhz), and RecCap UE can only monitor and process the PRS transmitted with a limited bandwidth (e.g., 20Mhz).

[0046] However, as shown in Figure 4, a short switching time that enables RF readjustment between adjacent hops can be utilized for RedCap UE to measure the received hopping PRS, limited by its monitoring and processing capabilities. The requirements for reference signal timing difference (RSTD), PRS-reference signal received power (RSRP), UE Rx-Tx time difference, PRS-road reference signal received power (RSRPP), and carrier phase / carrier phase difference measurement values for RedCap UE can be defined considering the readjustment time for PRS hopping. In the following examples, the PRS transmission opportunity can be a PRS repetition, a PRS period, a PRS sample, or a PRS instance. Example 1:

[0047] Once the physical layer receives the last ProvideAssistanceData and RequestLocationInformation messages, the RedCap UE may be able to measure RSTD, RSRP, RSRPP, RTT, and / or carrier phase / carrier phase difference measurements during the measurement period.

[0048] Regarding the hop count of a PRS resource, the following signaling is possible: The gNB / Location Management Function (LMF) may constitute the hop count of the PRS resource to the UE, or the UE may report to the network the number of supported frequency hops, or a factor associated with the hop count indicated as H. Alternatively, the UE may report the bandwidth for PRS reception at each hop (indicated as B1), and / or the gNB / LMF may constitute the transmission bandwidth per PRS resource (indicated as B2), and the hop count of the PRS resource is... [ka] It can be calculated as follows. If overlapping PRBs between adjacent hops are reported by the UE, the hop count H can be updated accordingly. As shown in Figure 5, frequency hopping of PRS can occur between different PRS transmission opportunities / PRS iterations. In some cases, frequency hopping of PRS reception occurs only between different PRS iterations, e.g., between PRS iterations.

[0049] In some cases, frequency hopping in PRS reception can occur between different PRS iterations and within a single PRS iteration, for example, within an intra-PRS iteration. Figure 6 illustrates hopping in inter-PRS iterations and intra-PRS iterations.

[0050] Measurement period requirement T meas,hop,Total teeth, [ka] or [ka] It can be defined as follows. meas can be RSTD, PRS-RSRP, UE Rx-Tx time difference, PRS-RSRPP, and carrier phase / carrier phase difference measurement values. H can be the number of hops of the PRS resource or a factor related to the number of hops of the PRS resource. For example,

[0051] For PRS-RSRP / PRS-RSRPP: [ka] That is the case.

[0052] In the case of Rx-Tx time difference: [ka] That is the case.

[0053] The measurement period in the RRC_INACTIVE and / or RRC_CONNECTED and / or RRC_IDLE states can be updated, for example, with a factor H associated with Rx hopping information that is applied to the calculation in a similar manner.

[0054] RedCap UE may report UE capabilities regarding PRS measurement. Capabilities may include one or more of the following: PRS processing capabilities, adjacent hop readjustment time, number of symbols between adjacent hops, number of symbols at each hop, indication of whether hopping is performed within a PRS transmission opportunity, or number of hops within a PRS transmission opportunity.

[0055] PRS processing capability may indicate the duration N of DL-PRS symbols that the UE can process per Tms, assuming the maximum DL-PRS bandwidth provided within the supported BandwidthPRS, in milliseconds; adjacent hop readjustment time refers to the switching time required to enable RF readjustment between adjacent hops; and the number of hops within a PRS transmission opportunity refers to the number of hops received by the UE within a PRS transmission opportunity, e.g., a single PRS iteration or sample, or instance.

[0056] The network may configure the UE with one or more of the following parameters: Factor H associated with hopping information, Parameter H1 associated with hopping information in PRS transmission, Parameter H2 associated with readjustment time between adjacent hops, Parameter H3 associated with the number of symbols between adjacent hops, Parameter H4 associated with the number of symbols at each hop, Parameter H5 associated with PRS transmission opportunities, or Factor H6 associated with measurement gap length and / or measurement gap duration. Alternatively, the UE may report the above parameters to the network. Example 2: Measurements related to H and H1

[0057] If no new PRS processing capacity exists specifically for PRS hopping, for example, the PRS processing capacity is the same as the duration of PRS processing without hopping. The reported hop count or the factor associated with the hop information (shown as H1) within a PRS transmission opportunity / iteration can be used to calculate the required measurement period. An example is shown in Figure 7, in which case the hop count within a PRS transmission opportunity / iteration is H1=2. Alternatively, the hop count within a PRS transmission opportunity may be configured in the RedCap UE by the gNB / LMF or reported to the network by the UE.

[0058] If the number of hops configured is not equal to the number of hops reported, H1 can take the smaller of the two values.

[0059] Measurement period T meas,hop,Total teeth, [ka] or [ka] It can be defined as follows: meas can be RSTD, PRS-RSRP, UE Rx-Tx time difference, PRS-RSRPP, and carrier phase measurements. For example, [ka] or [ka] That is the case. [ka] That is the case.

[0060] Alternatively, the measurement period in positioning frequency layer i is, [ka] or [ka] It can be extended as follows. Meas can be RSTD, PRS-RSRP, UE Rx-Tx time difference, PRS-RSRPP, and carrier phase measurements. For example, [ka] or [ka] That is the case. [ka] The factor H / H1 can be applied to calculations relating to the measurement period in positioning frequency layer i, and specifically, the measurement period in positioning frequency layer i can be updated as follows. For RSTD: [ka] That is the case.

[0061] For PRS-RSRP / PRS-RSRPP: [ka] That is the case.

[0062] In the case of Rx-Tx time difference:

Chem.

[0063] Alternatively, the above factor H / H1 can be replaced by floor(H / H1). Example 3: Measurements related to H and H2 / H3

[0064] The reported readjustment time for adjacent hops or the factor associated with the readjustment time (if reported, shown as H2 in units of symbol number) can be used to calculate the required measurement period.

[0072] Alternatively, the reported number of symbols between adjacent hops or the factor associated with the number of symbols between adjacent hops may include the number of symbols at each hop, i.e., the difference in symbol indices between the two hops. Under this condition, in Figure 8, the number of symbols between adjacent hops is equal to 2, i.e., the index difference between hop 1 and hop 2 can be H3 = 2. Example 4:

An example is shown in Figure 9, in which the readjustment time for adjacent hops or the number of symbols between adjacent hops is equal to 1, for example, H2 or H3=1, H4=2. Also, the number of hops within a PRS transmission opportunity [ka] It can be calculated as follows, where S is the number of PRS symbols in the current transmission opportunity (in this example, S=12). [ka] Figure 9 shows PRS hopping considering the readjustment time between hops and the required number of slots for each hop.

[0080] Alternatively, the reported number of symbols between adjacent hops or the factor associated with the number of symbols between adjacent hops can include the number of symbols per hop, i.e., the symbol index difference between two hops. Under this condition, in FIG. 9, the number of symbols between adjacent hops can be equal to 3, i.e., the index difference between hop 1 and hop 2 can be H3 = 3, and H3 = H2 + H4. Example 5:

[0081] When there is a new PRS processing capability dedicated to PRS hopping, for example, the PRS processing capability is different from durationOfPRS-Processing without hopping. For example, the new UE capability is defined as follows.

Table 1

[0082] durationOfPRS-Processing-hopping can be included in LPP, or more specifically, in NR-DL-PRS-ProcessingCapability, which assumes the maximum DL-PRS bandwidth provided within the supported BandwidthPRS, and the UE can process all T hop ms of the DL-PRS symbol duration N in ms hop can be shown. N hop The value of can be configured to be smaller than the PRS processing capability without hopping, T hopThe value of this can be configured to be greater than the PRS processing capacity without hopping.

[0083] The measurement period for RSTD in positioning frequency layer i is: [ka] It can be calculated as follows.

[0084] For PRS-RSRP / PRS-RSRPP: [ka] That is the case.

[0085] In the case of Rx-Tx time difference: [ka] [ka] That is the case. T hop This corresponds to durationOfPRS-ProcessingSymbolsInEveryTms defined within durationOfPRS-Processing-hopping, and N hop This corresponds to the durationOfPRS-ProcessingSysmbols defined within durationOfPRS-Processing-hopping.

[0086] Alternatively, the measurement period for RSTD in positioning frequency layer i is, [ka] It can be calculated as follows.

[0087] For PRS-RSRP / PRS-RSRPP: [ka] That is the case.

[0088] In the case of Rx-Tx time difference: [ka] That is the case. H is the number of hops for the PRS resource. hop This corresponds to the durationOfPRS-ProcessingSysmbols defined within durationOfPRS-Processing-hopping.

[0089] Similarly, the parameters {N,T} within the measurement period of PRS-RSRP, Rx-Tx timing difference, PRS-RSRPP, and carrier phase measurements also hop {N hop ,T hop This can be updated with UE capabilities reported using}.

[0090] The measurement period requirement may be specific to RedCap UE, and it incorporates the capabilities of RedCap UE. Example 6:

[0091] The gNB / LMF can configure the UE with one or more of the following parameters to specify UE measurement requirements for PRS: factors associated with hopping information, PRS transmission opportunities, factors associated with measurement gap length and / or measurement gap duration, frequency hopping PRS reception requirement information, number of symbols per hop, or readjustment / switching timing information.

[0092] Specifically, if the parameters are composed of LMF, the above information may be included in LPP, or more specifically, in the requested location information. If the parameters are composed of gNB, the above information may be included in the RRC signaling.

[0093] The factor associated with the hopping information may be the number of support frequency hops, or a scaling factor associated with the number of hops indicated as H.

[0094] Measurement period T for UE meas,hop,Total teeth, [ka] or [ka] It can be defined as follows: H is a factor related to the number of hops to a PRS resource, or the number of hops to a PRS resource.

[0095] Alternatively, the measurement period in positioning frequency layer i is, [ka] or [ka] It can be extended as follows. Meas can be RSTD, PRS-RSRP, UE Rx-Tx time difference, PRS-RSRPP, and carrier phase measurements.

[0096] The PRS transmission opportunity may be a factor associated with the number of PRS transmission opportunities or PRS transmission iterations required for the UE to sound, receive, or process the frequency-hopping PRS, or the number of PRS transmission opportunities with hopping indicated as H5. For example, if H=6 and H5=3, the UE must process 6 hops within 3 PRS transmission opportunities or 3 iterations. Alternatively, the PRS transmission opportunity may be associated with the configuration of the PRS, and more specifically, with the PRS iteration factor. The number of PRS transmission opportunities may be equal to the PRS iteration factor, or it may be less than or greater than the PRS iteration factor.

[0097] Measurement period T for UE meas,hop,Total teeth, [ka] or [Chem.] can be defined as follows.

[0098] Alternatively, the measurement period in the positioning frequency layer i is [Chem.] or [Chem.] can be extended as follows. meas can be RSTD, PRS-RSRP, UE Rx-Tx time difference, PRS-RSRPP, and carrier phase measurement values.

[0099] The factors associated with the measurement gap length and / or the measurement gap period refer to the factor F related to the configuration of the measurement gap. For example, the UE can process X hops within the measurement gap length, the required number in the measurement gap period can be H / X, and the factor H6 is [Chem.] can be equal to.

[0100] The frequency hopping PRS reception requirement information can be the UE processing requirement for the hopping PRS in the time domain. The configured PRS reception requirement information can be associated with the measurement gap configuration. For example, this parameter can limit the UE's ability to process a specific number of hops within a specific number of measurement gap periods H6 or to perform Rx hopping.

[0101] The measurement period T for the UE meas,hop,Total is [Chem.] or [Chem.] It can be defined as follows.

[0102] Alternatively, the measurement period in positioning frequency layer i is, [ka] or [ka] It can be extended as follows. Meas can be RSTD, PRS-RSRP, UE Rx-Tx time difference, PRS-RSRPP, carrier phase, and carrier phase difference measurements.

[0103] The measurement period in positioning frequency layer i is: [ka] Therefore, meas can be RSTD, PRS-RSRP, UE Rx-Tx time difference, PRS-RSRPP, carrier phase, and carrier phase difference measurements.

[0104] Alternatively, the above factor H6 can be replaced by H / H6 or floor(H / H6).

[0105] Alternatively, the configured PRS reception requirements information or Rx hopping requests may include time requirements. For example, this parameter could restrict the UE to processing a certain number of hops within Xms.

[0106] Alternatively, the configured PRS reception requirements information or Rx hopping request may include parameters associated with the PRS configuration. For example, this parameter may restrict the UE to process a certain number of hops or PRS within a certain number of PRS transmission periods E. For instance, if the PRS period is X and the configured / requested number of PRS periods is E, then the duration for UE measurement is X*E.

[0107] Alternatively, the configured PRS reception requirement information or Rx hopping requirements can include parameters associated with the configuration of the measurement gap. For example, this parameter can limit that the UE should process a specific number of hops or PRSs within a specific number of measurement gap repetitions. For example, if the repetition factor of the measurement gap is X and the configured / required number of measurement gaps is F, the duration of the UE measurement is X * F.

[0108] The number of symbols per hop indicates that a specific number of symbols for each hop for PRS reception, indicated as H4, can be configured by the network. For example, FIG. 10 is an example of configuring the number of symbols per hop as 2. FIG. 10 shows PRS hopping considering the number of symbols per hop.

[0109] The reconfiguration / switching timing information indicating the reconfiguration time between adjacent hops can be configured by the network. For example, the reconfiguration time can be configured in units of the number of symbols indicated as H2. Also, the number of hops within the PRS transmission opportunity is

[0111] [ka] or [ka] That is the case.

[0112] Alternatively, the measurement period in positioning frequency layer i may be extended as follows:

[0113] [ka] or [ka] or [ka] or [ka] The meas can be RSTD, PRS-RSRP, UE Rx-Tx time difference, PRS-RSRPP, and carrier phase measurements.

[0114] In the above embodiment, the PRS measurement can be determined by hopping-related information or timing requirements. The measurement period requirement may be more reasonable for RedCap UE. Example 7:

[0115] As shown in Figure 11, in the case of RedCap UE, the reference signals for positioning (e.g., sounding reference signal SRS, positioning reference signal PRS, sidelink positioning reference signal SL-PRS) can be transmitted via hopping. The SRS can hop within a slot (e.g., intra-slot hopping) and / or between slots (e.g., inter-slot hopping). In intra-slot hopping and inter-slot hopping, the duration between two adjacent hops may not be the same.

[0116] When a UE hops from one SRS transmission opportunity to the next, the UE can readjust its radio frequency (RF) chain (from one frequency to another). This readjustment takes a certain amount of time (e.g., 70 μs, 140 μs). During the readjustment time (or switching time), the UE cannot transmit or receive signals. The UE can report its ability to perform in-slot hopping for SRS. Alternatively, the UE can report its ability to perform in-slot hopping for SRS under / after a specific RF readjustment time.

[0117] An SRS transmission opportunity may be associated with a slot offset, symbol offset, start position, number of symbols, period and corresponding offset, repetition factor, and a list of available slot offsets / may be configured using a slot offset, symbol offset, start position, number of symbols, period and corresponding offset, repetition factor, and a list of available slot offsets. Alternatively, an SRS transmission opportunity with hopping may be associated with a slot offset, symbol offset, number of symbols, period and corresponding offset / may be configured using a slot offset, symbol offset, number of symbols, period and corresponding offset.

[0118] Alternatively, in the case of aperiodic SRS, the transmission opportunity with hopping may be configured using at least one of the following: slot offset (e.g., 0, 1, 2, ..., 100 for the slot for downlink control information DCI), symbol offset or start position (e.g., 0, 1, 2, ..., 13 in units of symbol count), and symbol count. Alternatively, a slot offset and / or symbol offset may be configured for SRS transmission opportunities after the first SRS transmission opportunity. For example, in the case of two slots containing SRS transmission opportunities, one slot offset for the first SRS transmission opportunity and another slot offset for the second SRS transmission opportunity may be configured separately. In another example, in the case of two slots containing SRS transmission opportunities, one slot offset for the first SRS transmission opportunity and another slot offset for the second SRS transmission opportunity may be configured separately, although the symbol offsets may be the same. Alternatively, this may apply when there is one / some downlink slots between these two adjacent SRS transmission opportunities (or between these two adjacent SRS hops).

[0119] Alternatively, in the case of period SRS / half-period SRS, the transmission opportunity with hopping may be configured using at least one of the period and corresponding offset (e.g., period of 10 slots, offset 0) and the number of symbols. Alternatively, for each hop or transmission opportunity of SRS with hopping, the period and corresponding offset are configured.

[0120] Alternatively, if one or more downlink slots exist between these two adjacent SRS transmission opportunities, these downlink slots are not counted in the calculation of the slot offset. That is, only uplink (UL) slots are counted when calculating the slot offset / period.

[0121] Alternatively, these SRS transmission opportunities (or hops) can be divided into several groups (e.g., two groups). Each group may have the same parameters (e.g., the same symbol offset, the same period, the same number of symbols). The parameters for different groups may differ.

[0122] For a given RedCap UE, there is at least one symbol between two adjacent hops of the SRS. Or, for a given RedCap UE, there is at least one symbol between two adjacent SRS transmission opportunities with hopping. Or, for a given RedCap UE, there is at least CombSize of symbols between two adjacent SRS transmission opportunities with hopping, where CombSize is the Comb size of the SRS (e.g., 1, 2, 3, 4, 6, 8, 12, 24, 36, 48). Or, symbols between two adjacent SRS transmission opportunities with hopping are not counted in the calculation of the symbol offset / start position. Or, symbols between two adjacent SRS transmission opportunities with hopping are not counted in the calculation of the actual symbol position with the symbol offset / start position.

[0123] In the case of SRS with hopping, if the number of configured symbols is Q (e.g., Q=4), CombSize=2, and the number of symbols for RF readjustment is T (e.g., if SCS=30kHz, T=2 with an RF readjustment time of 70μs), then at most floor((QT) / CombSize)=floor((4-2) / 2)=1 SRS transmission opportunities with hopping exist within this slot.

[0124] This method enables SRS hopping for RedCap UE, which can improve positioning accuracy (as it forms a larger effective bandwidth after hopping).

[0125] It should be understood that one or more features from the above embodiments are not limited to any particular embodiment and can be combined in any way (for example, in any priority and / or order, simultaneously or otherwise).

In general, Method 1100 can be implemented in some embodiments by a wireless communication device (e.g., UE) or a wireless communication node (e.g., BS or gNB). Depending on the embodiment, Method 1200 may perform additional, fewer, or different operations. At least one aspect of the operation relates to a system, method, apparatus, or computer-readable medium.

[0127] A wireless communication device (e.g., UE) may receive configuration information for a positioning reference signal from a wireless communication node (e.g., BS). The wireless communication device may transmit a positioning reference signal to the wireless communication node. The configuration information may indicate that the wireless communication device is configured to report the wireless communication device's ability to perform in-slot hopping to transmit a positioning reference signal within a given RF readjustment time. The configuration information may indicate that an SRS transmission opportunity with hopping is configured using at least one of a slot offset, a symbol offset, a number of symbols, or a period and a corresponding offset. The configuration information may indicate that for two slots, each containing a first SRS transmission opportunity and a second SRS transmission opportunity, the first slot offset for the first SRS transmission opportunity and the second slot offset for the second SRS transmission opportunity are configured separately, although their respective symbol offsets are identical to each other. The configuration information may indicate that for each SRS transmission opportunity with each hop or hopping of the SRS, a period and a corresponding offset are configured.

[0128] In some embodiments, configuration information may indicate that for a given RedCap UE, there are at least CombSize symbols between two adjacent SRS transmission opportunities with hopping or between two adjacent SRS hops, where CombSize is the Comb size of the SRS. Configuration information may indicate that symbols between two adjacent SRS transmission opportunities with hopping are not counted when determining the start position. Configuration information may indicate that for an SRS with hopping, if the number of configured symbols is Q and the number of symbols for RF readjustment is T, there are at most floor((QT) / CombSize) SRS transmission opportunities with hopping in the slot, where CombSize is the Comb size of the SRS.

[0129] In some embodiments, a wireless communication device may receive a request from a wireless communication node for Rx hopping of a reference signal for positioning.
