Description

Technical Field

[0001] Some example embodiments may generally relate to mobile or wireless telecommunication systems, such as Long Term Evolution (LTE) or fifth generation (5G) radio access technology or new radio (NR) access technology, or other communication systems such as future wireless communication networks. For example, certain example embodiments may relate to apparatus, systems and / or methods for radio resource management measurements for low power high frequency accuracy positioning with a substantially extended discontinuous reception period. Background Art

[0002] Examples of mobile or wireless telecommunication systems may include Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN), LTE Evolved UTRAN (E-UTRAN), Advanced LTE (LTE-A), MulteFire, LTE-A Pro, fifth generation (5G) radio access technology or NR access technology and / or 5G-Advanced. 5G wireless systems refer to the next generation (NG) of radio systems and network architectures. 5G network technology is mainly based on NR technology. However, 5G (or NG) networks can also be built on E-UTRAN radios. It is estimated that NR can provide bit rates of about 10-20Gbit / s or higher, and can support at least enhanced mobile broadband (eMBB) and ultra-reliable low-latency communication (URLLC) and massive machine type communication (mMTC). NR is expected to deliver extreme broadband and ultra-robust, low-latency connectivity and large-scale networking to support IoT.

[0003] When a device has an extended discontinuous reception (eDRX) cycle, there is a significant amount of time when the device is dormant or otherwise performing limited functionality. Due to the limited window for reception, it can be time consuming for the device to become synchronized with the network or other devices attempting to communicate with the device.

[0033] It will be readily appreciated that the components of certain example embodiments as generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.The following is a detailed description of some example embodiments of low power high frequency accuracy positioning with substantially extended discontinuous reception cycles.

[0034] The features, structures, or characteristics of the example embodiments described throughout this specification may be combined in any suitable manner in one or more example embodiments. For example, the use of the phrases "certain embodiments," "example embodiments," "some embodiments," "various embodiments," or other similar language throughout this specification refers to the fact that a particular feature, structure, or characteristic described in conjunction with an embodiment may be included in at least one embodiment. Therefore, the phrases "in certain embodiments," "example embodiments," "in some embodiments," "in other embodiments," or other similar language appearing throughout this specification do not necessarily refer to the same set of embodiments, and the described features, structures, or characteristics may be combined in any suitable manner in one or more example embodiments. In addition, the terms "base station," "cell," "node," "gNB," "network," or other similar language may be used interchangeably throughout this specification.

[0035] As used herein, “at least one of: ” and “at least one of ” and similar expressions (wherein a list of two or more elements is connected by “and” or “or”) refer to at least any one of the elements, or at least any two or more of the elements, or at least all of the elements.

[0036] The UE may be connected to a network and electronically share information through the network, such as a cell network. In order to optimally communicate with the network, it may be advantageous to accurately know the UE location. The following example embodiments may prevent a positioning session from being unable to accurately estimate the UE's location even when the UE is in an extended discontinuous reception (eDRX) cycle with a limited reception window.

[0037] Figure 1 An example flow chart 1000 is shown of communications between a user equipment (UE) 100 and a network 200 according to certain example embodiments. The UE may be a user device such as a cellular phone, a computer, a laptop, a tablet, etc. The network 200 may be a 5G network or other network including a base station, a server, a location management function (LMF) implemented on a server or other hardware, etc.

[0038] At S1020, the network 200 (at the base station) may send a positioning reference signal (PRS) or a series of positioning reference signals to the UE 100. The UE 100 may receive the positioning reference signal. The network 200 may periodically send the PRS, and the PRS may be used to locate various devices connected to the network 200. The UE 100 may be in an extended discontinuous reception (eDRX) cycle, in which the UE 100 processes only signals received during a periodic paging time window (PTW) in each cycle of the eDRX cycle. The UE 100 may be in eDRX for power saving. If the second PRS is not received in the PTW, the UE 100 may not be able to perform positioning measurements on the PRS. Therefore, the positioning interval of the PRS may be too large and / or may not be synchronized with the eDRX cycle of the UE 100.

[0039] At S1020, the UE 100 may determine information related to additional radio resource management measurements. The PRS is an example of radio resource management (RRM). The UE 100 may determine that PRS signaling is received too frequently or is received out of synchronization with the PTW, so that there is a synchronization failure.

[0040] The UE 100 may determine that the UE 100 is out of synchronization and measure neighboring cells for cell reselection. The UE 100 may perform serving cell measurement / reference cell measurement. If the serving cell / reference cell measurement fails, or if the UE is out of synchronization, the UE 100 may perform neighboring cell measurement. If the reselection condition is met, the cell reselection may be performed.

[0041] At S1030, the UE 100 may send an indication of the timing of the location reference signal to the network 200. The indication may include an indication of synchronization failure, or another indication that the PRS is received in a manner that positioning measurements in the PTW of the eDRX cycle are blocked.

[0042] At S1040, the network 200 may send and the UE 100 may receive at least one condition that triggers additional radio resource management measurements, the additional radio resource management measurements being used to perform at least one of positioning measurements or transmitting positioning sounding reference signals. The network 200 at the LMF may determine which condition(s) to send. The at least one condition may include UE conditions, channel conditions, signal conditions, measurement requirements, etc. In some embodiments, some or all of the conditions may be stored at the UE 100, and operations S1030 and S1040 may be skipped.

[0043] At least one condition may include performing additional measurements when the UE 100 may be in sleep mode for a duration. For example, downlink (DL) PRS positioning measurements or transmitting uplink (UL) positioning SRS outside the PTW. At least one condition may include performing additional measurements when UE mobility exceeds a certain threshold (e.g., if UE mobility is high, the UE performs additional RRM measurements, and if UE mobility is low, the UE does not necessarily perform additional RRM measurements). At least one condition may include performing additional measurements when the received signal power (e.g., reference signal received power (RSRP), reference signal received quality (RSRQ), signal to interference plus noise ratio (SINR)) of the most recently measured synchronization signal block (SSB) does not exceed a certain threshold (e.g., if the most recently measured RSRP from the SSB is low, the UE performs additional PRM measurements).

[0044] In some other examples of at least one condition, if the next PRS measurement opportunity does not overlap with any PTW of the eDRX cycle, the UE 100 may measure the closest SSB before performing the PRS measurement. The network 200 may also expect or anticipate the UE 100 behavior and send the PRS at normal intervals so that the UE 100 may anticipate the PRS. If the UE is instructed to obtain a high-accuracy positioning measurement, the network expects or anticipates the UE to increase the number of additional RRM measurement samples outside the PTW. At least one condition may include: when a high-accuracy positioning measurement is required, performing additional measurements, the RRM measurement frequency may be further increased. For example, when the UE is set to measure two samples for additional RRM measurement, the UE may determine to measure four SSB samples to enhance the accuracy of synchronization. At least one condition may include: when a wireless channel measurement (e.g., a service quality class identifier (CQI), RSRP, and / or SINR) between the UE and the gNB is less than a predefined threshold, performing additional measurements, the UE may perform additional RRM measurements outside the PTW. The UE may perform SSB measurements before the next upcoming PRS measurement until the PRS measurement opportunity overlaps with the next second PTW. If the downlink reference timing and / or uplink transmission timing is changed above a predefined threshold, the UE 100 may perform additional RRM measurements outside the PTW before the next PRS measurement.A substantial change in the downlink reception reference timing may occur if the UE 100 moves to another cell within the validity area.

[0045] Additional RRM measurements may also be configured. The RRM measurement frequency may be initially defined as a specific value (e.g., one SSB measurement in every X (>0) PRS measurements outside of the PTW). The RRM measurement frequency may be implemented as an additional RRM (SSB) measurement period. For example, the value of the RRM measurement frequency may be lower than the short CP length by an extended cyclic prefix (CP) length. This is due to the fact that the extended CP is robust for maintaining synchronization, so less frequent RRM measurements are required when the extended CP is configured. This may be combined with other options from one or more conditions.

[0046] At S1050, the UE 100 may determine whether at least one condition for triggering additional RRM measurement is satisfied, the additional RRM measurement being used to perform at least one of the following: positioning measurement, transmission of a positioning sounding reference signal (SRS). SRS is another example of RRM.

[0047] At S1060, the UE 100 and / or the network 200 may send an RRM signal. The UE 100 may receive one or more PRSs from the network or send a PSR signal to the network 200.

[0048] At S1070, the UE 100 may perform positioning measurements based on the RRM signal. One or more PRSs may be measured outside the PTW of the eDRX. The positioning measurements may include time of arrival (ToA), signal strength measurements, channel quality measurements, or other measurements useful for determining the positioning of the UE.

[0049] At S1080 , UE 100 may send positioning measurements to network 200 .

[0050] At S1090, the network 200 at the LMF may determine the location of the UE 100. In an example embodiment, the gNB of the network 200 receives positioning measurements from the UE 100 at S1080 and provides the positioning measurements to the LMF of the network 200. The LMF determines the location of the UE based on the positioning measurements from the UE 100. In another example embodiment, the UE 100 transmits a positioning SRS, and the base station (gNB) of the network 200 receives the positioning SRS. The gNB of the network 200 performs positioning measurements, such as RTOA (Relative Time of Arrival), and provides the obtained measurements to the LMF of the network 200. The LMF of the network 200 determines the location of the UE 100 based on the measurements obtained from the gNB of the network 200.

[0051] At S1100 , the LMF of the network may establish a communication condition with the UE 100 based on the determined location, and the UE 100 and the network 200 may communicate.

[0052] Figure 2Another example flow diagram 2000 of communications between a user device and a network is shown according to some example embodiments. Figure 2 The operation can be combined with Figure 1 For example, Figure 2 The operation can be Figure 1 Executed after the operation.

[0053] At S2010, the LMF of the network 200 may determine that the accuracy of the determined location of the user equipment 100 is below a threshold. The threshold may be set based on positioning accuracy requirements, measurement quality reported by the user equipment, communication type, connection quality, network conditions, etc.

[0054] At S2020, the network 200 may send and the UE 100 may receive configuration regarding additional RRM measurements from the gNB of the network 200. For example, the gNB of the network 200 will provide a configuration for performing a series of RRM measurements that may be aligned or not aligned with the eDRX cycle of the UE 100.

[0055] At S2030, the UE 100 may configure the UE 100 to receive the PRS at the timing indicated in the configuration. The UE 100 may reconfigure the eDRX cycle to align the PTW with the PRS to be received or may be reconfigured to perform measurements other than the PTW. In an example embodiment, an explicit indication of additional RRM measurements may be included in the configuration of the LMF or gNB from the network 200. The network 200 activates additional RRM measurements via RRC signaling. When additional RRM measurements are not activated, if the UE is not synchronized, the UE changes the RRC state to connected mode and a new cell is searched. When additional RRM measurements are activated, as initialization, the UE determines the number of PRS measurements and the corresponding time period for the additional RRM measurements.

[0056] At S2040 , the UE 100 and the network 200 may perform positioning measurements based on the configuration. The UE 100 may receive the PRS and perform RRM measurements based on the PRS, and the UE may also send the SRS. The UE 100 may send measurements to the network 200 .

[0057] At S2050 , the network 200 may determine the location of the UE 100 .

[0058] At S2060 , the network 200 may communicate with the UE 100 based on the determined location of the user equipment.

[0059] Figure 3 An example flow chart 3000 of a method according to certain example embodiments is shown. In an example embodiment, Figure 3The method may be performed by a network entity or a group of multiple network elements (NEs) in a 3GPP system (such as LTE or 5G-NR). For example, in an example embodiment, Figure 3 The method can be performed by a UE or a computer implementing an application and / or AF, and the UE and the computer are similar to Fig. 9 One of the devices 10 or 20 shown in .

[0060] According to certain example embodiments, Figure 3 The method may include: at S3010, obtaining a first condition related to additional radio resource management measurements; at S3020, determining whether at least a portion of the first condition triggering the additional radio resource management measurements is met; and at S3030, in response to at least a portion of the first condition being met, performing additional radio resource management measurements, wherein the additional radio resource management measurements are outside a set of periodic paging time windows, and the additional radio resource management measurements are performed for performing at least one of positioning measurements or transmitting positioning detection reference signals.

[0061] Figure 4 An example flow chart 4000 of another method according to certain example embodiments is shown. In an example embodiment, Figure 4 The method may be performed by a network entity or a set of multiple network elements in a 3GPP system (such as LTE or 5G-NR). For example, in an example embodiment, Figure 4 The method can be similar to Fig. 9 The method is performed by a network (e.g., a gNB, a 5G core, or a 5G RAN) of one of the devices 10 or 20 shown in FIG.

[0062] According to certain example embodiments, Figure 4 The method may include: at S4010, determining, by a network entity, a first condition related to additional radio resource management measurements; at S4020, providing or configuring the first condition to one or more user equipment; at S4030, receiving a report about additional radio resource management measurements from one or more user equipment, wherein the additional radio resource management measurements are outside a set of periodic paging time windows, and the additional radio resource management measurements are performed for performing at least one of positioning measurements or transmitting positioning detection reference signals, and wherein the additional radio resource management measurements are performed in response to at least a portion of the first condition being satisfied.

[0063] Figure 5 An example flow chart of a method for controlling a network according to certain example embodiments is shown. In an example embodiment, Figure 5The method may be performed by a network entity or a set of multiple network elements in a 3GPP system (such as LTE or 5G-NR). For example, in an example embodiment, Figure 5 The method may be performed by a network element implementing LMF, the network element being similar to Fig. 9 One of the devices 10 or 20 shown.

[0064] According to certain example embodiments, Figure 5 The method may include: at S5010, receiving a positioning measurement of a user equipment; at S5020, evaluating the accuracy of the received positioning measurement; and at S5030, at least in part based on the evaluated accuracy, requesting a network entity to configure a first condition related to additional radio resource management measurements to the user equipment.

[0065] Figure 6 An example timing diagram of location signals and measurements according to some example embodiments is shown. The timing diagram shows the RRM signal and the eDRX cycle of the UE 100. The timing diagram also shows the positioning intervals between the PRS signal and potential measurements at the UE 100. Figure 6 The timing diagram of shows an example of one of the options for performing RRM signaling and measurements outside of the PTW of the eDRX cycle. The UE 100 may determine that the next PRS measurement opportunity does not overlap with any PTW measurement and measure the SSB before the closest PRS before the PTW of the eDRX cycle. The network 200 may also expect or anticipate this UE 100 behavior and send the PRS at normal intervals so that the UE 100 can expect the PRS. Therefore, the RRM measurement may be performed by the UE 100. The PRS measurement may also be replaced with a positioning SRS transmission.

[0066] Figure 7 Another example timing diagram of location signals and measurements according to some example embodiments is shown. The UE 100 determines that high accuracy positioning measurements are required, the RRM measurement frequency may be further increased (e.g., to 4), and the UE may determine to measure four SSB samples to enhance the accuracy of synchronization. The SSB samples may be measured outside the PTW window.

[0067] Figure 8 Another example timing diagram of location signals and measurements according to some example embodiments is shown. If the UE determines that the downlink reference timing and / or uplink transmission timing change is above a predefined threshold (e.g., a downlink reference timing error occurs), the UE 100 may perform additional RRM measurements outside of the PTW by performing SSB measurements.

In certain example embodiments, apparatuses 10 and 20 may be elements in a communication network or associated with such a network. For example, apparatus 10 may be an AF or application implemented on a computing device or machine (e.g., an EH-UE), and apparatus 20 may be a network (i.e., a gNB, 5GS, 5G core, 5G RAN, etc.).

[0069] In some example embodiments, the apparatuses 10 and 20 may include one or more processors, one or more computer-readable storage media (e.g., memory, storage device, etc.), one or more radio access components (e.g., modem, transceiver, etc.), and / or a user interface.
