Description

Technical Field

[0001] This document generally relates to relaxed positioning reference signal (PRS) rules and relaxed sounding reference signal (SRS) rules for wireless communications. Background Art

[0002] Low power high accuracy positioning (LPHAP) user equipment can reduce power consumption when performing high-precision positioning, especially in the RRC_INACTIVE (RRC inactive) state and the RRC_IDLE (RRC idle) state. When the user equipment is in the RRC_INACTIVE state or the RRC_IDLE state, it can wake up to receive each positioning reference signal (PRS) indicated by the location management function (LMF), and can send a sounding reference signal (SRS) configured by the network, which may result in greater ramp-up power consumption and / or ramp-down power consumption. Ways to reduce this type of power consumption may be worth pursuing. Summary of the invention

[0014] Figure 1 A diagram of an example wireless communication system 100 is shown, which includes a plurality of communication nodes (or just nodes) configured to wirelessly communicate with each other. Typically, these communication nodes include at least one user equipment 102 and at least one radio access node 104. Figure 1The example wireless communication system 100 in FIG. 1 is shown as including two user equipments 102, including a first user equipment 102(1) and a second user equipment 102(2), and one wireless access node 104. However, various other examples of the wireless communication system 100 including any of various combinations of one or more user equipments 102 and / or one or more wireless access nodes 104 are possible.

[0015] Typically, a user device as described herein, such as user device 102, may include a single electronic device or apparatus capable of wireless communication over a network, or multiple electronic devices or apparatuses (e.g., a network of multiple electronic devices or apparatuses). A user device may include or otherwise be referred to as a user terminal, user terminal device, or user equipment (UE). In addition, a user device may be or include, but is not limited to: a mobile device (as a non-limiting example, such as a mobile phone, a smart phone, a smart watch, a tablet computer, a laptop computer, a vehicle or other carrier (as a non-limiting example, a carrier driven by a human, a motor or an engine, such as a car, an airplane, a train, a ship or a bicycle)), or a fixed or stationary device (as a non-limiting example, such as a desktop computer or other computing device that is not usually moved for a long time, such as an appliance, other relatively heavy devices including the Internet of things (IoT), or a computing device used in a commercial or industrial environment). In various embodiments, the user device 102 may include a transceiver circuit 106 coupled to an antenna 108 to enable wireless communication with the wireless access node 104. The transceiver circuit 106 may also be coupled to a processor 110, which may also be coupled to a memory 112 or other storage device. The memory 112 may store therein instructions or codes that, when read and executed by the processor 110, cause the processor 110 to implement various methods as described herein.

[0016] In addition, generally, as described herein, a wireless access node, such as a wireless access node 104, may include at least one device, electronic device or apparatus, and / or network device or apparatus, and may include one or more base stations or other wireless network access points that are capable of wirelessly communicating with one or more user devices and / or with one or more other wireless access nodes 104 over a network. For example, in various embodiments, the wireless access node 104 may include at least one of the following: a 4G LTE base station, a 5G NR base station, a 5G centralized unit base station, a 5G distributed unit base station, a next generation Node B (gNB), an enhanced Node B (eNB), or other similar base stations or next generation (e.g., 6G (sixth generation)) base stations, or a location management function (LMF). The wireless access node 104 may include a transceiver circuit 114 coupled to an antenna 116, which may include an antenna tower 118 in various ways to enable wireless communication with the user device 102 or another wireless access node 104. The transceiver circuit 114 may also be coupled to one or more processors 120, which may also be coupled to a memory 122 or other storage device. The memory 122 may store therein instructions or codes that, when read and executed by the processor 120, cause the processor 120 to implement one or more of the methods described herein.

[0017] Figure 2 1 is a block diagram of an example configuration of a wireless communication node 104. In this example configuration, the wireless access node 104 may include a location management function (LMF) 202 and one or more radio access network (RAN) nodes 204. Some embodiments may include only one RAN node 204. Other embodiments, such as Figure 2 As shown, a plurality or n RAN nodes 204(1) to 204(n) may be included, where n is two or more than two. In addition, each component of the wireless access node 104 (such as the LMF 202 and each RAN node 204), such as by having a processor 120, a memory 122, a transceiver circuit 114, an antenna 116 and / or an antenna tower 118 (such as for the wireless access node 104 as Figure 1 ), may include at least one network device, and / or may be configured in the form of hardware or a combination of hardware and software.

[0018] In addition, if Figure 2As shown, the LMF 202 and each of the RAN nodes 204 may be configured to communicate (send and receive) with each other, such as signals or messages, and may be configured to communicate (send and receive) with one or more user equipment 102 directly or indirectly via another component of the wireless access node 104. For example, the LMF 202 may communicate directly with the user equipment 102. In a specific embodiment, the LMF 202 may communicate directly with the user equipment 102 according to the Long-Term Evolution (LTE) positioning protocol (LTE positioning protocol, LPP) (i.e., via LPP signaling). In addition, the RAN node 204 may communicate directly with the user equipment 102. In a specific embodiment, the RAN node 204 may communicate directly with the user equipment 102 at least via radio resource control (RRC) signaling. In addition, the LMF 202 may communicate directly with each RAN node 204. In certain embodiments, the LMF 202 may communicate directly with each RAN node 204 in accordance with the New Radio Positioning Protocol A (NRPPa) (i.e., via NRPPa signaling). In addition, for at least some embodiments, such as Figure 2 As shown, each RAN node 204 may include one or more subcomponents. For example, the RAN node 204 may include a gNB and / or at least one transmission / reception point (TRP) 208. Further functionality of the LMF 202 and the RAN node 204 is described in more detail below.

[0019] In addition, review Figure 1In various embodiments, two communication nodes in the wireless system 100, such as a user equipment 102 and a wireless access node 104, two user equipment 102 without a wireless access node 104, or two wireless access nodes 104 without a user equipment 102, may be configured to wirelessly communicate with each other in or through a mobile network and / or a wireless access network according to one or more standards and / or specifications. In general, the standards and / or specifications may define rules or procedures by which communication nodes may communicate wirelessly, which, in various embodiments, may include those rules and procedures for communicating in millimeter (mm) bands and / or those rules and procedures for communicating using multiple antenna schemes and beamforming capabilities. Additionally or alternatively, the standards and / or specifications are those defining radio access technologies and / or cellular technologies, such as, as non-limiting examples, Fourth Generation (4G) Long Term Evolution (LTE), Fifth Generation (5G) New Radio (NR), or New Radio Unlicensed (NR-U).

[0020] In addition, in the wireless system 100, the communication nodes are configured to wirelessly communicate signals with each other. Generally, depending on the perspective of a particular node in the communication, the communication between two communication nodes in the wireless system 100 can be or include sending or receiving, and generally the sending and receiving are performed simultaneously. For example, for a given communication between a first node and a second node (wherein the first node is sending a signal to the second node and the second node is receiving a signal from the first node), the first node can be referred to as a source node or device or a sending node or device, the second node can be referred to as a destination node or device or a receiving node or device, and the communication can be considered as sending for the first node and receiving for the second node. Of course, since the communication nodes in the wireless system 100 can both send and receive signals, a single communication node can be a sending / source node and a receiving / destination node at the same time, or switch between being a source / sending node and being a destination / receiving node.

[0021] In addition, a specific signal may be characterized or defined as an uplink (UL) signal, a downlink (DL) signal, or a sidelink (SL) signal. An uplink signal is a signal sent from the user equipment 102 to the wireless access node 104. A downlink signal is a signal sent from the wireless access node 104 to the user equipment 102. A sidelink signal is a signal sent from one user equipment 102 to another user equipment 102, or a signal sent from one wireless access node 104 to another wireless access node 104. In addition, for sidelink transmission, the first / source user equipment 102 directly sends the sidelink signal to the second / destination user equipment 102 without forwarding any of the sidelink signal to the wireless access node 104.

[0022] In addition, signals communicated between communication nodes in the system 100 can be characterized or defined as data signals or control signals. Typically, a data signal is a signal that includes or carries data, such as multimedia data (e.g., voice data and / or image data), while a control signal is a signal that carries control information that configures the communication nodes in a particular manner so that the communication nodes communicate with each other, or that otherwise controls how the communication nodes communicate data signals with each other. In addition, a particular signal can be defined or characterized by a combination of data / control and uplink / downlink / sidelink, the combination including an uplink control signal, an uplink data signal, a downlink control signal, a downlink data signal, a sidelink control signal, and a sidelink data signal.

[0023] For at least some specifications, such as 5G NR, data signals and control signals are transmitted and / or carried on physical channels. Typically, a physical channel corresponds to a set of time-frequency resources used for signal transmission. Different types of physical channels can be used to transmit different types of signals. For example, a physical data channel (or just a data channel) is used to transmit data signals, and a physical control channel (or just a control channel) is used to transmit control signals. Example types of physical data channels include, but are not limited to, a physical downlink shared channel (PDSCH) for communicating downlink data signals, a physical uplink shared channel (PUSCH) for communicating uplink data signals, and a physical sidelink shared channel (PSSCH) for communicating sidelink data signals. In addition, example types of physical control channels include, but are not limited to: a physical downlink control channel (PDCCH) for communicating downlink control signals, a physical uplink control channel (PUCCH) for communicating uplink control signals, and a physical sidelink control channel (PSCCH) for communicating sidelink control signals. As used herein, for simplicity, unless otherwise specified, a particular type of physical channel is also used to refer to a signal transmitted on the particular type of physical channel, and / or a transmission on the particular type of transmission. As an example, PDSCH refers to the physical downlink shared channel itself, a downlink data signal transmitted on the PDSCH, or a downlink data transmission. Therefore, a communication node sending or receiving a PDSCH means that the communication node sends or receives a signal on the PDSCH.

[0024] In addition, for at least some specifications such as 5G NR and / or for at least some types of control signals, the control signal transmitted by the communication node may include control information, which includes information required to enable the transmission of one or more data signals between the communication nodes and / or schedule one or more data channels (or one or more transmissions on the data channels). For example, such control information may include information required to correctly receive, decode and demodulate data signals received on a physical data channel during data transmission, and / or information required for an uplink scheduling grant that notifies the user equipment of resources and transmission formats for uplink data transmission. In some embodiments, the control information includes downlink control information (DCI) sent from the radio access node 104 to the user equipment 102 in the downlink direction. In other embodiments, the control information includes uplink control information (UCI) sent from the user equipment 102 to the radio access node 104 in the uplink direction, or sidelink control information (SCI) sent from one user equipment 102 (1) to another user equipment 102 (2) in the sidelink direction.

[0025] In addition, in some embodiments, the user equipment 102 can receive and / or measure synchronization signal blocks (SSBs) from a serving cell and / or a neighboring cell in a radio resource control (RRC) inactive state (e.g., RRC_INACTIVE) and / or an RRC idle state (e.g., RRC_IDLE) to perform radio resource management (RRM) measurements. In various embodiments, the SSB can be configured to be measured in a period, which is referred to as an SSB measurement timing configuration (SMTC). In some embodiments, if the user equipment meets a certain condition, the user equipment 102 can perform a relaxed RRM measurement by shortening the SSB measurement.

[0026] In addition, in some embodiments, when the positioning service is triggered, the user equipment 102 may be scheduled to receive a positioning reference signal (PRS) in an RRC inactive state (e.g., RRC_INACTIVE) and / or in an RRC idle state (e.g., RRC_IDLE), and / or the user equipment 102 may send a sounding reference signal (SRS) in an RRC inactive state (e.g., RRC_INACTIVE) and / or in an RRC idle state (e.g., RRC_IDLE). In some embodiments, each time the user equipment 102 receives a PRS, SSB, DCI, and / or PDSCH, and / or each time the user equipment 102 sends an SRS, the user equipment 102 may wake up from a sleep mode (e.g., a deep sleep, a light sleep, or an ultra-sleep mode) to an active mode.

[0027] Furthermore, in at least some embodiments of positioning, the PRS is sent by the serving TRP 208 and / or one or more neighboring TRPs 208. However, the PRS configurations for all TRPs 208 are sent by the LMF 202. Furthermore, in some embodiments, at least some capabilities of the user equipment 102 are reported to the serving gNB 206 via RRC signaling, and / or at least some capabilities of the user equipment 102 are reported to the LMF 202 via LTE Positioning Protocol (LPP) signaling. The user equipment 102 may report its measurement results of PRS-related measurements to the LMF 202 via LPP signaling.

At block 302, a user equipment 102 may determine that the user equipment 102 satisfies a condition.

[0065] In addition, in some embodiments of method 300 and / or method 400, at least one network device may receive a report from user equipment 102 on the ability of user equipment 102 to support the determination condition, the first condition, or the second condition. For at least some of these embodiments, the report on the ability to support the determination condition, the first condition, or the second condition may include a report on the ability of user equipment 102 to determine whether the user equipment 102 satisfies the condition, the first condition, or the second condition.

[0066] In addition, in some embodiments of method 300 and / or method 400, at least one network device may receive a report from user equipment 102 on the user equipment's ability to support at least one of performing relaxed PRS measurements according to relaxed PRS measurement rules or performing relaxed SRS transmissions according to relaxed SRS transmission rules.

[0067] Further details of method 300 and / or method 400 are now described.

[0068] In some embodiments, if the user equipment 102 meets the conditions, the user equipment 102 may perform relaxed PRS measurement according to the relaxed PRS measurement rule. In some of these embodiments, the relaxed PRS measurement rule may include at least one relaxed PRS configuration configured from the LMF 202 or the gNB 206 (via at least one of dedicated LPP or RRC signaling, or via RRC broadcast signaling). In other embodiments, the relaxed PRS measurement rule may be part of a specification or standard, such as in the form of a predefined relaxed rule, and the user equipment 102 is configured to operate or comply with a part of the specification or standard.

[0069] In addition or alternatively, at least one network device (such as LMF 202 and / or gNB 206) may configure different relaxed PRS configurations corresponding to different conditions. If the user equipment 102 meets the condition, the user equipment 102 may adopt a relaxed PRS configuration corresponding to the condition and may perform relaxed PRS measurement.

[0070] In addition, for at least some embodiments, at least one network device (such as LMF 202 and / or gNB 206) may configure a timer or duration associated with the condition. In the event that the user equipment 102 satisfies the condition before the time expires or within the duration, the user equipment 102 may adopt a corresponding relaxed PRS configuration and may perform relaxed positioning measurements. In other embodiments, the timer and / or duration may be predefined, rather than at least one network device configuring the time or duration (such as via explicit signaling). In addition or alternatively, at least one network device (such as LMF 202 and / or gNB 206) may also configure a valid area associated with the condition. In the event that the user equipment 102 satisfies the condition within the valid area, the user equipment 102 may adopt a corresponding relaxed PRS configuration and may perform relaxed positioning measurements. For at least some embodiments, the valid area may include a cell list or a TRP list. In addition or alternatively, the valid area configured for delay enhancement may be reused for a valid area in which the user equipment 102 may satisfy the condition.

[0071] Additionally or alternatively, in some embodiments, the user equipment 102 may report the condition satisfied by the user equipment 102 to at least one network device (e.g., gNB 206 and / or LMF 202). Or in response, at least one network device (e.g., LMF 202 and / or gNB 206) may send a corresponding relaxed PRS configuration to the user equipment 102. Then, the user equipment 102 may adopt the corresponding relaxed PRS configuration and perform relaxed positioning measurements. In some of these embodiments, the user equipment 102 may be configured with a timer or duration and / or a validity area from at least one network device. Then, the user equipment 102 may monitor the condition during the timer / duration and / or in the validity area. Furthermore, in some embodiments, the timer / duration may be predefined or preconfigured so that the timer or duration may not be configured for the user equipment 102 using explicit signaling. For at least some of these embodiments, the user equipment 102 may also report a timer or duration associated with the condition. At least one network device may determine that the user equipment 102 satisfies the condition until the timer or duration expires. Additionally or alternatively, the user equipment 102 may report a validity area associated with the condition. At least one network device may determine that the user equipment 102 will satisfy the condition within the validity area. For at least some embodiments, the validity area may include a list of cells or a list of TRPs 208.

[0072] Additionally or alternatively, in some embodiments, if the user equipment 102 meets the condition, the user equipment 102 may perform relaxed PRS measurements according to one or more predefined relaxed rules. The predefined relaxed rules may be rules included in the standard or specification according to which the communication node communicates in the wireless communication network 100. Additionally or alternatively, the predefined relaxed rules may include at least one relaxed PRS configuration to be adopted by the user equipment 102. Different conditions may correspond to different predefined relaxed rules. Additionally or alternatively, the predefined relaxed rules may be associated with a timer or duration during which the user equipment 102 will perform relaxed positioning measurements. Additionally or alternatively, the predefined relaxed rules may be associated with a valid area in which the user equipment 102 will perform relaxed positioning measurements. For at least some embodiments, the valid area may include a cell list or a TRP 208 list.

[0073] In addition, for at least some embodiments, the conditions that the user equipment 102 can satisfy may include at least one of the following items (for example, a single item of the following items, or a combination of two or more of the following items): low mobility standard; UE is not at the cell edge standard; medium mobility state standard; normal mobility state standard; stationary standard; stationary not at the cell edge standard; the user equipment is at a specific signal strength level; the user equipment is a low power high precision positioning (LPHAP) user equipment; the user equipment 102 supports relaxed PRS configuration; the user equipment 102 supports relaxed PRS measurement; the user equipment 102 is in a radio resource control (RRC) inactive state (for example, RRC_INACTIVE); the user equipment 102 is in an RRC idle state (for example, RRC_IDLE); or the user equipment is in an RRC connected state (for example, RRC_CONNECTED). Therefore, the user equipment 102 can determine that non-limiting example conditions to be met include: the user equipment 102 meets the low mobility standard but does not meet the UE is not at the cell edge standard; the user equipment 102 meets the UE is not at the cell edge standard but does not meet the low mobility standard; the user equipment 102 meets the low mobility standard and the UE is not at the cell edge standard; the user equipment 102 does not meet the low mobility standard and the UE is not at the cell edge standard; the user equipment 102 meets the low mobility standard and also meets a specific signal strength level; the user equipment 102 meets the UE is not at the cell edge standard and also meets a specific signal strength level; the user equipment 102 meets the low mobility standard and the UE is not at the cell edge standard and also meets a specific signal strength level.

[0074] Additionally, in some embodiments, for example, the user equipment 102 may "reuse" a condition for relaxed PRS measurement or relaxed SRS transmission (such as radio resource management (RRM) relaxed measurement) that the user equipment 102 used for another action or event. In the event that the user equipment 102 determines that the condition for the other action or event is satisfied, then the user equipment 102 may "reuse" the condition for relaxed PRS measurement and / or relaxed SRS transmission, such as by adopting a corresponding relaxed PRS configuration and / or relaxed SRS configuration corresponding to the condition. Various embodiments of the user equipment 102 "reusing" a condition are described in more detail below.

[0075] Additionally or alternatively, the user equipment 102 may reuse the low mobility criteria configured for radio resource management (RRM) relaxed measurements in system information block type 2 (SIB2) to determine whether the user equipment 102 should perform relaxed positioning measurements. For at least some embodiments, the gNB 206 may configure a lowMobilityEvaluation including s-SearchDeltaP and t-SearchDeltaP, and the relaxed measurement criteria for the user equipment 102 with low mobility is met when the following conditions are met:

[0076] -(Srxlev Ref –Srxlev) SearchDeltaP ,

[0077] in:

[0078] - Srxlev = current Srxlev value of the serving cell (dB).

[0079] -Srxlev Ref = reference Srxlev value of the serving cell (dB), set as follows:

[0080] - after selecting or reselecting a new cell, or

[0081] -if (Srxlev-Srxlev Ref )>0, or

[0082] - If targeting T SearchDeltaP The relaxed measurement criteria have not been met:

[0083] -UE shall set Srxlev Ref The value of is set to the current Srxlev value of the serving cell.

[0084] Srxlev can be measured based on SSB or PRS​Ref and SrxLev.

[0085] In other embodiments, at least one network device (e.g., gNB 206) may configure parameters of a low mobility standard dedicated to relaxed positioning measurements and notify the user equipment 102 in broadcast signaling or dedicated signaling. The broadcast signaling may be a positioning system information block (SIB) or a common SIB (such as SIB2 / 3 / 4, etc.). In addition, the dedicated signaling may be an RRC release message or an RRC reconfiguration message. Specifically, at least one network device (e.g., gNB 206) may configure a threshold A for relaxed positioning measurements (similar to s-SearchDeltaP) and a threshold B for relaxed positioning measurements (similar to t-SearchDeltaP). The judgment rules may be the same as those described above.

[0086] Additionally or alternatively, the user equipment 102 may reuse the UE not at the cell edge criterion configured for RRM relaxed measurements in SIB2 to determine whether the user equipment 102 should perform relaxed positioning measurements. In particular, in these embodiments, at least one network device (e.g., gNB 206) may configure cellEdgeEvaluation including s-SearchThresholdP and s-SearchThresholdQ, and the relaxed measurement criterion for UE not at the cell edge may be met when the following conditions are met:

[0087] -Srxlev>S SearchThresholdP ,and

[0088] -Squal>S SearchThresholdQ If S is configured SearchThresholdQ If

[0089] in:

[0090] - Srxlev = current Srxlev value of the serving cell (dB).

[0091] - Squal = current Squal value of the serving cell (dB).

[0092] Squal and Srxlev may be measured based on SSB or PRS.

[0093] In other embodiments, at least one network device (e.g., gNB 206) may configure parameters of the UE not at the cell edge criterion dedicated to relaxed positioning measurements and notify the user equipment 102 in broadcast signaling or dedicated signaling. For at least some embodiments, the broadcast signaling may be a positioning SIB or a normal SIB (such as SIB2 / 3 / 4, etc.). In addition, the dedicated signaling may be an RRC release message or an RRC reconfiguration message. In a specific embodiment, at least one network device (e.g., gNB 206) may configure a threshold C for relaxed positioning measurements (similar to s-SearchThresholdP) and a threshold D for relaxed positioning measurements (similar to s-SearchThresholdQ). The judgment rules may be the same as those described above.

[0094] In addition or alternatively, the user equipment 102 may reuse a combined indication for RRM relaxed measurement in a relaxed positioning measurement (e.g., a combineRelaxedMeasCondition indication in SIB2). The combined indication may configure the user equipment 102 to meet both the low mobility criterion and the UE not being at the cell edge criterion to meet the relaxed measurement requirements for cell reselection. If the combined indication is and / or is set to a specific value (e.g., a value corresponding to a Boolean value TRUE), the user equipment 102 may perform relaxed positioning measurements when both the UE not being at the cell edge criterion and the low mobility criterion are met.

[0095] In addition or alternatively, in some embodiments, the user equipment 102 may be configured with an indication dedicated to relaxed positioning measurements in broadcast signaling or dedicated signaling. The indication may indicate that the user equipment 102 may perform relaxed positioning measurements only when the user equipment 102 meets both the low mobility standard and the UE is not at the cell edge standard. In addition, for at least some embodiments, the broadcast signaling may be a positioning SIB or a normal SIB (such as SIB2 / 3 / 4, etc.), and the dedicated signaling may be an RRC release message. For at least some embodiments, if the indication is present, the user equipment 102 may perform relaxed positioning measurements when both the UE is not at the cell edge standard and the low mobility standard are met.

[0096] Additionally or alternatively, the user equipment 102 may reuse the normal mobility state criteria configured in SIB2 to determine the relaxed PRS configuration and relaxed positioning measurements. For at least some embodiments, if the parameter (T CRmax 、N CR_H 、N CR_M , T CRmaxHystand cellEquivalentSize), the mobility state of the user equipment 102 may be determined. Additionally or alternatively, for at least some of these embodiments, the state detection criteria may include a common mobility state criterion, which may include: if within a time period T CRmax The number of cell reselections during this period is less than N CR_M , and if in time period T CRmaxHyst If no criteria for the medium mobility state or the high mobility state are detected during this period, the user equipment 102 may enter the normal mobility state.

[0097] Additionally or alternatively, in some embodiments, the user equipment 102 may reuse the medium mobility state criteria configured in SIB2 to determine a relaxed PRS configuration and / or a relaxed positioning measurement. In some of these embodiments, if the parameter (T CRmax 、N CR_H 、N CR_M , T CRmaxHyst and cellEquivalentSize), the mobility state of the user equipment 102 may be determined. Additionally or alternatively, for at least some of these embodiments, the state detection criteria may include a medium mobility state criterion, which may include: if within a time period T CRmax The number of cell reselections during the period is greater than or equal to N CR_M But less than or equal to N CR_H , and if criteria for a medium mobility state are detected, the user equipment 102 may enter the medium mobility state.

[0098] Additionally or alternatively, in some embodiments, the user equipment 102 may reuse the stationary state criteria configured for the RedCap UE to determine a relaxed PRS configuration and / or relaxed positioning measurements. For at least some of these embodiments, the relaxed measurement criteria for a stationary RedCap UE is met when:

[0099] -(Srxlev RefStationary –Srxlev) SearchDeltaP-Stationary ,

[0100] in:

[0101] - Srxlev = current Srxlev value of the serving cell (dB).

[0102] -Srxlev RefStationary = reference Srxlev value of the serving cell (dB), set as follows: ​

[0103] - after selecting or reselecting a new cell, or

[0104] -if (Srxlev-Srxlev RefStationary )>0, or

[0105] - If targeting T SearchDeltaP-Stationary The relaxed measurement criteria have not been met:

[0106] -The user equipment 102 should set Srxlev RefStationary The value of is set to the current SrxLev value of the serving cell.

[0107] Srxlev can be measured based on SSB or PRS RefStationary and SrxLev.

[0108] Additionally or alternatively, in some embodiments, the user equipment 102 may reuse the stationary and not-at-cell-edge criteria configured for RedCap UEs to determine relaxed PRS configurations and / or relaxed positioning measurements. For at least some of these embodiments, the relaxed measurement criteria for stationary RedCap UEs not at the cell edge are met when the following conditions are met:

[0109] -For T SearchDeltaP-Stationary The relaxed measurement criteria in Section 5.2.4.9.3 are met.

[0110] -Srxlev>S SearchThresholdP2 ,as well as

[0111] -Squal>S SearchThresholdQ2 If S is configured SearchThresholdQ2 words.

[0112] in:

[0113] - Srxlev = current Srxlev value of the serving cell (dB).

[0114] - Squal = current Squal value of the serving cell (dB).

[0115] Squal and Srxlev may be measured based on SSB or PRS.

[0116] Additionally or alternatively, in some embodiments, for relaxed PRS measurement, the signal strength level is determined by the user equipment 102 measuring the PRS of its current camping cell or each TRP 208. The relaxed PRS measurement may include at least one of the following items: PRS-RSRP, PRS-RSRQ, or PRS-RSRPP. Additionally or alternatively, the user equipment 102 may measure at least A PRS samples of B PRS resources in the camping cell or each TRP 208, and the user equipment 102 may perform a weighted average of these PRS measurement values ​​and derive the PRS measurement value of the cell or TRP 208 to perform the corresponding relaxed PRS measurement. For at least some of these embodiments, A and / or B may be predefined or explicit signaling from at least one network device.

[0117] In other embodiments, the user equipment 102 may measure at least A PRS samples of B PRS resources in the camped cell or each TRP 208 within a time period. The user equipment 102 may average these PRS measurements in the time period and derive the PRS measurement value of the cell or TRP 208 to perform corresponding relaxed PRS measurements. For at least some of these embodiments, A, B and / or the time period may be predefined or explicitly signaled from at least one network device.

[0118] In addition, for at least some embodiments, there may be multiple signal strength levels, where each level is described as a power range in dBm (e.g., from x dBm to y dBm) or a single power value in dBm. Additionally or alternatively, if the PRS measurement value of the cell or TRP 208 is within a specific power range, the user equipment 102 can determine that the user equipment 102 meets the specific strength level of the relaxed PRS measurement.

[0119] Additionally or alternatively, for at least some embodiments, the relaxed PRS configuration includes at least one of the following:

[0120] a plurality of PRS resources within a plurality of selected TRPs 208, such as the first A TRPs 208 in nr-SelectedDL-PRS-IndexListPerFreq or the first A TRPs 208 in nr-DL-PRS-AssistanceDataPerFreq list for downlink time difference of arrival (DL-TDOA), downlink angle of departure (DL-AoD), and / or multiple round-trip time (RTT) positioning methods;

[0121] a plurality of PRS resources within a plurality of selected cells, wherein, for example, the user equipment 102 only receives and measures PRS from the selected cells and ignores PRS from other cells;

[0122] A plurality of PRS resources within a plurality of selected PRS frequency layers, the plurality of selected PRS frequency layers being, for example, the first B PFLs (PRS frequency layers) in the NR-SelectedDL-PRS-IndexList or the first B PFLs in the nr-DL-PRS-AssistanceDataList list for DL-TDOA, DL-AoD and / or multi-RTT positioning methods;

[0123] One or more selected PRS resource sets, such as the first C PRS resource sets in dl-SelectedPRS-ResourceSetIndexList or the first C PRS resource sets in nr-DL-PRS-ResourceSetList for DL-TDOA, DL-AoD and / or multi-RTT positioning methods;

[0124] One or more selected PRS resources, such as the first D PRS resources in dl-SelectedPRS-ResourceIndexList or the first D PRS resources in the dl-PRS-ResourceList list for DL-TDOA, DL-AoD and / or multi-RTT positioning methods;

[0130] A plurality of PRS resources including a reduced or decreased PRS repetition factor, such as, for example, for a relaxed PRS configuration, the maximum repetition factor may be less than 2 / 4 / 5 / 8 / 16 / 32, or the relaxed PRS configuration may not support PRS repetition.

[0131] In addition, in some embodiments, the signaling of the relaxed PRS configuration can be a new information element (IE), which includes the relaxed PRS configuration. In some of these embodiments, the IE can also include the corresponding conditions (if any) in the relaxed PRS configuration. In addition or alternatively, each relaxed PRS configuration can be associated with each item in the LPP signaling.

[0132] In addition, for at least some embodiments, signaling communication may be performed between network devices of the wireless access node 104 (e.g., between one or more RAN nodes 204, gNB 206 and / or TRP 208, and LMF 202) and / or between one or more network devices of the wireless access node 104 and the user equipment 102 to support relaxed positioning measurements. For at least some of these embodiments, the LMF 202 may request the RAN node 204 to provide one or more relaxed PRS configurations, each relaxed PRS configuration for a corresponding different condition. In addition or alternatively, the RAN node 204 may respond to the request of the LMF 202 by including one or more relaxed PRS configurations for one or more different conditions. In addition or alternatively, the LMF 202 may send one or more relaxed PRS configurations corresponding to one or more different conditions to the user equipment 102 (e.g., via LPP signaling). Additionally or alternatively, the LMF 202 may send one or more relaxed PRS configurations for all TRPs 208 to a serving RAN node 204 (e.g., a nearest serving RAN node 204). The (nearest) serving NG-RAN node 204 may then send one or more relaxed PRS configurations to the user equipment 102 (such as via broadcast signaling or DL ​​RRC signaling). Additionally or alternatively, at least one network device (such as the LMF 202 or the gNB 206) may request the user equipment 102 to report conditions currently satisfied by the user equipment 102. Additionally or alternatively, the user equipment 102 may request a relaxed PRS configuration from at least one network device (such as the LMF 202 or the gNB 206) to perform relaxed positioning measurements. Additionally or alternatively, at least one network device (such as the LMF 202 or the gNB 206) may send a trigger indication to trigger the user equipment 102 to perform relaxed positioning measurements. Additionally or alternatively, the user equipment 102 may report to at least one network device (such as LMF 202 or gNB 206) whether the user equipment 102 is capable of supporting the ability to determine different conditions, such as whether the user equipment 102 is capable of determining whether the user equipment 102 is capable of satisfying one or more of the different conditions. Additionally or alternatively, the user equipment 102 may report to at least one network device (such as LMF 202 or gNB 206) whether the user equipment 102 is capable of supporting the ability to perform relaxed positioning measurements or relaxed PRS configuration.

[0133] In addition, in some embodiments, if the user equipment 102 satisfies one or more conditions, the user equipment 102 may perform relaxed radio resource management (RRM) measurements. The one or more conditions may include at least one of the following:

[0134] The user equipment 102 is configured with specific parameters of the low mobility criterion, and the user equipment 102 can measure the SSB and meet the low mobility criterion;

[0135] The user equipment 102 may be configured with specific parameters of the UE not at the cell edge criterion, and the user equipment 102 may measure the SSB and satisfy the UE not at the cell edge criterion; or

[0136] The user equipment 102 may be configured with an indication that when both the low mobility criterion and the UE not being at the cell edge criterion are met, the user equipment 102 may perform relaxed RRM measurements, and / or in the case where the user equipment 102 is configured with specific parameters for both the low mobility criterion and the UE not being at the cell edge criterion, the user equipment 102 may measure the SSB and find that the user equipment 102 meets both criteria.

[0137] For at least some embodiments in which user equipment 102 performs relaxed RRM measurements in response to one or more conditions, user equipment 102 (eg, LPHAP user equipment) can take advantage of power savings when performing positioning.

[0138] In addition, in some embodiments, the user equipment 102 can perform relaxed RRM measurements by reducing the SSB, which can save energy of the user equipment. In order to further reduce SSB reception in the RRC idle state (e.g., RRC_IDLE) or in the RRC inactive state (e.g., RRC_INACTIVE), especially when the user equipment 102 may need to save energy when performing positioning, under some conditions, the user equipment 102 can measure the SSB only in the time when the corresponding SSB measurement timing configuration (SMTC) overlaps with the PRS reception window. For example, the user equipment 102 can be configured with inter-frequency cell measurement for cell reselection in the system information block type 4 (SIB4), and each SMTC is configured with each center frequency of the SS (synchronization signal) block of the neighboring cell. At the same time, the user equipment 102 can be triggered for positioning services, and the PRS reception window is configured for the RRC inactive (e.g., RRC_INACTIVE) state and / or the RRC idle (RRC_IDLE) state. Then, the user equipment 102 can receive and measure the PRS only within the PRS reception window. Under some conditions, the user equipment 102 may not need to perform frequent RRM measurements. Under these conditions, the user equipment 102 may further receive and measure SSBs only when the corresponding SMTC overlaps the PRS reception window. Figure 5 1 is a timing diagram showing an example overlap of SMTC and the PRS receive window. Correspondingly, there may be two falling cases. In the first case, the signal SMTC (such as Figure 5A specific duration within SMTC1 in FIG. 5 may drop, or certain SMTC instances (in the cycle of SMTC), such as SMTC2 in FIG. 5 , may drop.

[0139] Further references Figure 5 In some embodiments, the user equipment 102 may measure the SSB only during or at a time when the corresponding SMTC overlaps the PRS reception window in response to one or more second conditions. For at least some embodiments, the one or more second conditions may include at least one of the following: a low mobility criterion; a UE not at a cell edge criterion; the user equipment 102 is a LPHAP user equipment; the user equipment 102 is in a positioning service, and / or the user equipment is receiving and / or measuring PRS from the TRP 208; the user equipment 102 supports relaxed RRM measurements; the user equipment 102 is in an RRC inactive (e.g., RRC_INACTIVE) state; the user equipment is in an RRC idle (e.g., RRC_IDLE) state; or the user equipment is in an RRC connected (e.g., RRC_CONNECTED) state.

[0140] In addition, in some embodiments, when the user equipment 102 meets the conditions, the user equipment 102 may perform relaxed sounding reference signal (SRS) transmission according to a relaxed SRS transmission rule. The relaxed SRS transmission rule may include at least one relaxed SRS configuration, and at least in some embodiments, the at least one relaxed SRS configuration may be configured from at least one network device (such as LMF 202 or gNB 206). In some embodiments, at least one relaxed SRS configuration may be configured via at least one of dedicated LPP signaling or RRC signaling or via RRC broadcast signaling. In other embodiments, the relaxed SRS transmission rule may be part of a specification or standard, and the user equipment is configured to operate or comply with a part of the specification or standard. For such other embodiments, the relaxed SRS transmission rule may be one or more predefined relaxed rules, or may be part of one or more predefined relaxed rules.

[0141] In addition, in some embodiments, the user equipment 102 can be configured with an SRS configuration for positioning via RRC signaling to perform uplink time difference of arrival (UL-TDOA), uplink angle of arrival (UL-AoA), and multiple round trip time (RTT) positioning. In addition, in some embodiments, when the user equipment 102 is in an RRC connected (e.g., RRC_CONNECTED) state, the SRS configuration can be provided in SRS-Config in bandwidth part (BWP)-UplinkDedicated IE (Bandwidth part (BWP)-Uplink dedicated IE). In addition, in an RRC inactive (e.g., RRC_INACTIVE) state, the SRS configuration can be provided in srs-PosRRC-Inactive in SuspendConfig in an RRC release message.

[0142] In addition, in some embodiments, at least one network device (e.g., gNB 206) may configure a plurality of different relaxed SRS configurations, each relaxed SRS configuration corresponding to a different condition among the plurality of conditions. If the user equipment 102 satisfies the condition, the user equipment 102 may adopt the corresponding relaxed SRS configuration, and may send the SRS according to the corresponding relaxed SRS configuration.
