Conditional measurement reporting

Abstract

Embodiments of the present disclosure relate to conditional measurement reporting. A terminal device receives a first message from a network device, the first message including one or more conditions indicating a relative level of one or more measurements performed by the terminal device. Based on determining that at least one of the relative level of one or more conditions is satisfied, the terminal device reports the one or more measurements to the network device by sending a second message. In this way, unnecessary signaling and power consumption at the terminal device side can be avoided, thereby saving energy.

Description

Technical Field

[0001] Various example embodiments relate to the field of telecommunications, and more particularly to methods, devices, apparatus, and computer-readable storage media for condition measurement reporting. Background Art

[0002] As communication systems evolve, new technologies have been proposed. Reduced Capability (RedCap) positioning is an agenda item within the Release 18 (Rel-18) Study Item (SI) on Enhanced Positioning. RedCap positioning involves positioning of terminal equipment (UE) with reduced capabilities, where the main driving factors are low energy consumed at the terminal equipment and the cost of the terminal equipment.

[0003] In many cases, RedCap positioning involves finding the coordinates of terminal devices with low mobility (i.e., they may occasionally move from one area to another) with relatively low accuracy (i.e., the rough location of the device is required at the "area" level (e.g., which area within a warehouse or factory hall) or the "room" level (e.g., which room within a building)). In this case, the RedCap device will not need to report its position for a long time, because the position remains the same (again, at the area level or room level). However, the Third Generation Partnership Project (3GPP) standards involve periodic measurement reporting (for UE-assisted positioning) or position reporting (for UE-based positioning) from the device to the network, and there is no known mechanism in the standards that allows a RedCap device to indicate to the network that its position has changed "noticeably", which corresponds to a change in the area or room it is in. It still needs to further improve the solution for conditional measurement reporting. Summary of the invention

[0004] In general, example embodiments of the present disclosure provide a solution for conditional measurement reporting.

[0005] The solution may suggest that the RedCap device (generally, can be applied to terminal devices or UE) will not need to report its location for a long time, because the location remains the same (again at the area or room level), so that the RedCap device can save energy. Once the RedCap device moves to a new location and stays there for a considerable period of time, the network should be updated with the new location of the RedCap device. However, unless the RedCap device moves to a new location again, no frequent updates are required on the RedCap device side.

The embodiments of the present disclosure can be applied to various communication systems. In view of the rapid development of communication, there will certainly be future types of communication technologies and systems, using which the present disclosure can be embodied. This should not be regarded as limiting the scope of the present disclosure to the above-mentioned systems.

[0041] As used herein, the term "network device" refers to a node in a communication network, via which a terminal device accesses the network and receives services therefrom. A network device may refer to a base station (BS), a location management function (LMF) or an access point (AP), for example, a node B (NodeB or NB), an evolved node B (eNodeB or eNB), a NR NB (also referred to as a gNB), a remote radio unit (RRU), a radio head (RH), a remote radio head (RRH), a relay, a low power node (such as a femto and pico, etc.), a non-terrestrial network (NTN) or non-terrestrial network equipment (such as satellite network equipment, a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite, and a geosynchronous orbit (GEO) satellite), an aircraft network equipment, etc., depending on the terminology and technology applied.

[0042] The term "terminal device" refers to any terminal device that may be capable of wireless communication. As an example and not limitation, a terminal device may also be referred to as a communication device, a user equipment (UE), a subscriber station (SS), a portable user station, a mobile station (MS), or an access terminal (AT). The terminal device may include, but is not limited to, a mobile phone, a cellular phone, a smart phone, a voice over IP (VoIP) phone, a wireless local loop phone, a tablet computer, a wearable terminal device, a personal digital assistant (PDA), a portable computer, a desktop computer, an image capture terminal device (such as a digital camera), a game terminal device, a music storage and playback device, a vehicle-mounted wireless terminal device, a wireless endpoint, a mobile station, a laptop embedded device (LEE), a laptop mounted device (LME), a USB dongle, a smart device, a wireless client device (CPE), an Internet of Things (IoT) device, a watch or other wearable device, a head mounted display (HMD), a vehicle, a drone, medical equipment and applications (such as remote surgery), industrial equipment and applications (such as robots and / or other wireless devices operating in the context of industrial and / or automated processing chains), consumer electronic devices, equipment operating on commercial and / or industrial wireless networks, etc. In the following description, the terms "terminal device", "communication device", "terminal", "user equipment" and "UE" may be used interchangeably.

[0043] The term “RedCap device” refers to terminal devices with reduced capabilities. In 5G New Radio (NR) Release 17, 3GPP introduced a new tier of reduced capability (RedCap) devices, also known as NR-Light. This is a new device platform that bridges the capability and complexity gap between the extremes in 5G today with an optimized design for mid-tier use cases. Compared to 5G enhanced mobile broadband (eMBB) devices that may support gigabits per second throughput in both downlink and uplink, RedCap devices can effectively support 150Mbps and 50Mbps in downlink and uplink respectively, due to design optimizations. The reduced complexity contributes to more cost-effective RedCap devices, longer battery life due to lower power consumption, and a smaller device footprint, enabling newer designs for a wide range of use cases.

[0044] RedCap positioning is an agenda item in Rel-18 SI on enhanced positioning. RedCap positioning involves positioning of devices with reduced capabilities (RedCap), where the main drivers are low energy consumed at the terminal device 120 and the cost of the device.

[0045] In many cases, RedCap positioning involves finding the coordinates of end devices with low mobility (i.e., they may occasionally move from one area to another) with relatively low accuracy (i.e., the rough location of the device needs to be at the "area" level (e.g., which area within a warehouse or factory hall) or the "room" level (e.g., which room within a building)).

[0046] In this case, the RedCap devices will not need to report their location for a long time, as the location remains the same (again at the zone level or room level), allowing them to save energy. Once a device moves to a new location and stays there for quite some time, the network should be updated with the new location of the device. However, unless the device moves to a new location again, frequent updates are not required on the device side.

[0047] There is no known mechanism in the standards that allows a RedCap device to indicate to the network that its location has changed "noticeably", corresponding to a change in area or room. Instead, the 3GPP standards involve periodic measurement reports (for UE-assisted positioning) or position reports (for UE-based positioning) from the device to the network. Using this traditional approach results in unnecessary signaling and power consumption on the device side, as the device will need to report measurements or location regardless of the level of location detail required. Even if the Location Services (LCS) Quality of Service (QoS) indicates a low accuracy requirement, there is no known mechanism to convert this relaxed QoS into conditional reporting from the device.

[0048] Therefore, there is a gap in the standard such that a RedCap device may not be configured to report (measurements or locations) only if there is an indication that the device is in a new area or room. Although the above analysis is provided primarily based on RedCap devices, it should be noted that there may also be some challenges or issues when normal terminal devices are considered.

[0049] According to an embodiment of the present disclosure, a solution for conditional measurement reporting is provided. In the solution, a terminal device receives a first message from a network device, and the first message may include one or more conditions indicating the relative levels of one or more measurements performed by the terminal device. In addition, the terminal device reports the one or more measurements to the network device by sending a second message based on at least one of the one or more conditions for determining the relative levels being satisfied. In this way, unnecessary signaling and power consumption can be avoided, thereby saving energy. An exemplary embodiment of the present disclosure for determining the identity of a terminal device will be described below with reference to Figures 1 to 8 is described.

[0050] Figure 1 An example communication environment 100 is shown in which example embodiments of the present disclosure may be implemented. The environment 100 may be part of a communication network, including a serving cell 101, a first transmission reception point (TRP) 105, a second TRP 110, a third TRP 115, a terminal device 120, and a network device 130. It should be understood that the number of TRPs shown in the environment 100 is for illustration purposes only, but does not limit the scope of the present disclosure in any way.

[0051] UE 120 (hereinafter also referred to as "terminal device 120" or "user equipment 120") and network device 130 (hereinafter also referred to as "location management function (LMF)" or "LMF 130") can transmit data and control information to each other via TRP 105 (hereinafter also referred to as "first TRP 105"), TRP 110 (hereinafter also referred to as "second TRP 110") and TRP 115 (hereinafter also referred to as "third TRP 115") within the coverage of service cell 101. In another embodiment, network device 130 may be a network node, such as a gNB, including the functionality of LMF integrated therein.

[0052] It should be understood that the number of network devices and terminal devices is only for illustrative purposes and does not imply any limitation. System 100 can include any suitable number of network devices and terminal devices for implementing embodiments of the present disclosure. Although not shown, it will be understood that one or more terminal devices can be located in environment 100.

[0053] The communication in the communication system 100 may be implemented according to any appropriate (multiple) communication protocols, which may include but are not limited to cellular communication protocols of the first generation (1G), second generation (2G), third generation (3G), fourth generation (4G), fifth generation (5G) and sixth generation (6G), wireless local area network communication protocols (such as Institute of Electrical and Electronics Engineers (IEEE) 802.11, etc.) and / or any other protocols currently known or to be developed in the future. In addition, the communication may utilize any appropriate wireless communication technology, which may include but are 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 access (OFDM), discrete Fourier transform spread OFDM (DFT-s-OFDM) and / or any other technology currently known or to be developed in the future.

[0054] Figure 2 A signaling diagram of an example process according to some embodiments of the present disclosure is shown. For the purpose of discussion, process 200 will refer to Figure 1 Process 200 may involve terminal device 120, network device 130, such as Figure 1 It should be understood that although the process 200 for linking has been Figure 1 The process is described in the communication system 100, but the process can also be applied to other communication scenarios.

[0055] In process flow 200, network device 130 may send 210 a first message to terminal device 120 (such as a RedCap device), which may include one or more conditions 202. One or more conditions 202 may indicate relative levels of one or more measurements performed by the terminal device. On the other side of the communication, terminal device 120 may receive a first message from network device 130, which may include one or more conditions 202. One or more conditions 202 indicate relative levels of one or more measurements performed by terminal device 120.

[0056] In some embodiments, one or more conditions 202 may be included as at least one information element in the first message. In an example, the network device 130 (e.g., LMF) may use a new information element (IE) in the LPPRequestLocationInformation message to locate the terminal device 120 (e.g., RedCap device). In this new IE, the network device 130 may provide the UE with the determined UE-specific conditions.

[0057] In some implementations, to report or update one or more location measurements of a terminal device 120 (UE 120 may be used interchangeably with terminal device 120, or RedCap UE throughout the description), receiving a first message from a network device 130 (LMF 130 may be used interchangeably with network device 130 having integrated functionality of LMF throughout the description) may be conditional on the network device 130 first defining one or more conditions of relative levels of one or more measurements that are at least partially satisfied by the terminal device 120. In one example, the network device 130 may obtain UE capabilities and identify that the terminal device 120 may be a RedCap UE. In one example, for the identified RedCap UE 120, the network device 130 may determine conditions regarding measurement reporting, and these conditions need to be satisfied by the terminal device in order for the terminal device 120 to report the measurements.

[0058] In some embodiments, one or more conditions are terminal device specific, which may be based on specifying at least one of the following: quality of service (QoS) for the positioning session of the terminal device 120, or desired area information of the terminal device 120. In one example, the condition may be defined as UE specific based on the QoS for the positioning session of the terminal device 120 and based on the desired area information of the UE.

[0059] In some embodiments, the one or more measurements performed by the terminal device 120 include at least one of: a combination of positioning reference signals (PRSs) from different transmission reception points (TRPs) to be measured by the terminal device 120 for reporting; a collected energy configuration of the terminal device; the duration between reports in the case of periodic positioning by the terminal device, or the maximum number of consecutive reports in the case of periodic positioning by the terminal device.

[0060] In one example, the new IE contains information about conditional reporting of positioning measurements or position estimation. The content of the IE includes: the PRS combination that needs to be measured by the terminal device 120 for the terminal device 120 to provide a report; the collection energy configuration; in the case of periodic positioning, the time between reports and the maximum number of consecutive reports.

[0061] In some embodiments, network device 130 may determine a PRS combination based on an expected area of ​​interest and topology of transmission reception points (TRPs).

[0062] After receiving the one or more conditions 202 from the network device 130, the terminal device 120 determines 220 whether at least one of the one or more conditions 202 of the relative level is met. In one example, the terminal device 120 checks the conditions in the new IE and provides a measurement report as part of the LPPProvideLocationInformation message only if the configured conditions are met.

[0063] In some embodiments, the terminal device 120 may measure a PRS combination for reporting based on determining that a change in reference signal received power (RSRP) exceeds a threshold.The PRS combination may be specific to location measurements.

[0064] In some embodiments, in order to determine that a condition indicating a relative level of measurements of PRS combinations from different transmission reception points (TRPs) performed by the terminal device 120 is satisfied, the terminal device 120 may determine 220 at least one or a combination of the following: the PRS received power has changed by more than a threshold or a defined relative power unit (dB); the measured arrival time difference has changed by more than a defined duration (s); or the PRS combination exceeds a configured limit.

[0065] Figure 3 An example environment for optimizing condition measurement reporting in some example embodiments of the present disclosure is shown. For the purpose of discussion, environment 300 will refer to Figure 1 Described. Figure 3 As shown, the terminal device 120 with low mobility may report measurements to the network device 130 when moving from area 1 to area 2. In one example, the terminal device 120 may not need to report positioning measurements unless entering another new area / room.

[0066] For example, a PRS combination (e.g., a PRS received from TRP #1 having an RSRP at least x dB stronger than any other detected TRP) needs to be measured by the terminal device 120 to report the measurement. The determination of the PRS combination that causes the report to be sent / not sent is made at the network device 130 and can be based on the expected area of ​​interest (e.g., Figure 3 1) and the topology of the TRP. For example, refer to Figure 3 , if the region of interest (region 1) corresponds to a relative distance to TRP#2 that is 2 times closer than either of the remaining two TRPs (TRP#1 and TRP#3), then this difference in proximity may correspond to a change in the associated received RSRP of 6dB (i.e., x=6dB in this example). In another network topology and / or another region of interest, the value x may be adjusted to the new topology and / or region.

[0067] The reason for this message is to ensure that the terminal device 120 does not report measurements if it is still in the same area (room, area, etc.). For example, if the terminal device 120 sees the same gNB much stronger than other gNBs for a period of time, this will give an indication that the area has not changed during this time.

[0068] In one example, if more than X number of measured PRS Rx powers (via reference signal received power RSRP) or more than X number of arrival time differences (via reference signal time difference RSTD) have changed by more than Y dB (for RSRP) or more than Y milliseconds (for RSTD), then a report ensue. In another example, a report shall ensue only if such a PRS received (Rx) power combination or PRS RSTD exceeds a configured limit. In yet another example, a report shall ensue only if a specified difference in PRS Rx power or PRS RSTD is measured.

[0069] In some embodiments, to determine that the condition indicating the measured relative level of the harvested energy configuration is met, the terminal device 120 may determine 220 that the harvested energy is greater than or equal to an energy threshold. In one example, where the terminal device 120 is harvesting energy, the energy harvested at the device is not less than X joules.

[0070] In some embodiments, the terminal device 120 may determine 220 a condition associated with the duration between reports based on determining that a time interval after sending a measurement report is equal to the duration between reports after determining that a condition associated with PRS combining is not met when the terminal device performs periodic positioning.

[0071] In one example, in the case of periodic reporting, a new IE (information element) may include a maximum time between reports. This is to ensure that even if the devices are in the same room, some reports are provided after a long time, thereby ensuring system stability.

[0072] In some embodiments, the terminal device 120 may determine 220 a condition associated with a maximum number of consecutive measurement reports based on determining that a condition associated with a PRS combination and a collected energy configuration is satisfied when the terminal device performs periodic positioning, wherein the terminal device 120 is caused to determine that the number of consecutive measurement reports that have been sent is less than the maximum number of consecutive measurement reports.

[0073] In one example, in the case of periodic reporting, the new IE includes the maximum number of consecutive reports to be provided to the network if conditions associated with PRS combining and collected energy are met.

[0074] In some embodiments, the reporting period is determined based on a scaling factor associated with the mobility of the terminal device. In one example, the lower the mobility, the longer the time between positioning reports.

[0075] Based on determining 220 that at least one of the one or more conditions 202 of the relative level is met, the terminal device 120 reports 225 the one or more measurements 204 by sending a second message to the network device 130. The network device 130 receives the one or more measurements 204 via the second message from the terminal device 120. In some embodiments, the RedCap UE may decide whether to provide a measurement report to the network device 130 based on any of the conditions configured above.

[0076] In some embodiments, based on determining 220 that none of the one or more conditions 202 of the relative level are satisfied, the terminal device 120 may report to the network device 130 via a second message (e.g., an LPPProvideLocationInformation message) without reporting the location measurement, which indicates that none of the conditions of the relative level have been satisfied by the terminal device 120. In one example, the terminal device 120 may implicitly indicate to the network device 130 that the condition is not satisfied by sending an empty input to the LPPProvideLocationInformation message.

[0077] In some embodiments, based on determining 220 that none of the one or more conditions 202 of the relative level are met, the terminal device 120 may report using an indication via a second message. The indication marks the one or more conditions of the relative level that have not been met by the terminal device. In one example, the terminal device 120 may mark the condition as not being met by initiating another new IE within the LPPProvideLocationInformation message.

[0078] In some embodiments, in response to receiving 215 the first message (e.g., LPPRequestLocationInformation message) from network device 130, terminal device 120 may send an indication that one or more conditions marking a relative level have not been met once.

[0079] In some embodiments, the first message comprises a request to provide a positioning related measurement message and the second message comprises the provision of the positioning related measurement message.

[0080] In some embodiments, in order to determine the location of the terminal device 120, the second message includes a location measurement or an update of a location measurement.

[0081] In some embodiments, the reporting of the location measurement of the terminal device 120 through the second message may be aperiodic. And, when one or more conditions 202 of the relative level are satisfied by the terminal device 120, the reporting of the location measurement occurs.

[0083] Figure 4 An example of an optimized condition measurement reporting process that may be used in example embodiments of the present disclosure is shown. Figure 4 An example of a new solution for a network to configure RedCap_UE with conditional measurement reports is given.

[0084] like Figure 4As shown, in step 410, LMF 130 may use QoS and expected area information to set conditions on measurement reporting. In step 420, LMF 130 may configure conditional reporting to RedCap_UE 120 by sending an LPPRequestLocationInformation message (i.e., a first message) to RedCap_UE 120. The LPPRequestLocationInformation message may carry the above-mentioned set conditions, and the set conditions may include PRS Rx power combination limits, collection energy configuration, and maximum continuous reporting. In step 430, after receiving the conditions from LMF 130, RedCap_UE 120 may check whether the configured conditions are met. In step 440, RedCap_UE 120 may then send an LPPProvideLocationInformation message (i.e., a second message) to LMF 130. When the configured conditions have been met by RedCap_UE 120, the LPPProvideLocationInformation message may carry the measurement report. When the configured condition is not met by the RedCap_UE 120, the LPPProvideLocationInformation message may not carry a measurement report, but may carry a new IE (Information Element) or an empty input marking that the configured condition is not met by the RedCap_UE 120. The new IE marking that the configured condition is not met by the RedCap_UE 120 may be sent only once as a response to the condition within the LPPRequestLocationInformation message. In step 450, the LMF 130 may obtain an update on the location of the RedCap_UE 120 based on a report of one or more measurements performed by the RedCap_UE 120.

[0085] In an embodiment, the network node gNB 132 may facilitate signaling for reporting setup conditions for one or more measurements performed by the RedCap_UE 120, and signaling for sending an LPPRequestLocationInformation message and an LPPProvideLocationInformation message to the LMF 130.
