[0045] 1, A-IOT Introduction

[0046] The environmental Internet of Things is a new type of wireless communication system that is largely self-sufficient by using energy from the environment. It is an ecosystem for connecting and automating a large number of objects and devices, each of which is connected using low-cost, self-powered sensor nodes to form a wireless sensor network device.

[0047] As one of the key mechanisms for power supply, the environmental Internet of Things relies on energy harvesting, so that it is not necessary to use cables to supply power or charge the batteries in mobile devices and smart objects. Vibrations from devices, machines and buildings, and the propagation of ambient radio signals can all be used to generate electricity.

[0048] Two possible A-IOT topologies under the 5G network device are given as follows:

[0049] In Topology 1, the Ambient IoT device directly and bidirectionally communicates with a base station. The communication between the base station and the ambient IoT device includes Ambient IoT data and / or signalling. This topology includes the possibility that the BS transmitting to the Ambient IoT device is a different from the BS receiving from the Ambient IoT device.

[0050] As shown in Figure 2, in Topology 1, the Ambient IoT device 210 directly communicates bidirectionally with a network device 220. The communication between the network device and the Ambient IoT device includes Ambient IoT data and / or signalling. This topology includes the possibility that the BS transmitting to the Ambient IoT device is different from the BS receiving from the Ambient IoT device.

[0051] In Topology 2, the Ambient IoT device communicates bidirectionally with an intermediate node between the device and basestation. In this topology, the intermediate node can be a relay, IAB node, UE, repeater, etc. which is capable of Ambient IoT. The intermediate node transfers Ambient IoT data and / or signalling between BS and the Ambient IoT device.

[0052] As shown in Figure 3, in Topology 2, the Ambient IoT device 310 communicates bi-directionally with an intermediate node 330 between the device and network equipment 320. In this topology, the intermediate node can be a relay, IAB (Integrated Access Backhaul), UE, repeater, etc. which is capable of ambient IoT. The intermediate node transmits ambient IoT data and / or signalling between the BS (Base Station) and the Ambient IoT device.

[0053] In Topology 3, the Ambient IoT device transmits data / signalling to a basestation, and receives data / signalling from the assisting node; or the Ambient IoT device receives data / signalling from a basestation and transmits data / signalling to the assisting node. In this topology, the assisting node can be a relay, IAB, UE, repeater, etc. which is capable of ambient IoT.

[0054] As shown in Figure 4, in Topology 3, the Ambient IoT device 410 transmits data / signalling to network equipment 420 and receives data / signalling from the assisting node 430; or the Ambient IoT device 410 receives data / signalling from network equipment 420 and transmits data / signalling to the assisting node 430. In this topology, the assisting node can be a relay, IAB, UE, repeater, etc. which is capable of ambient IoT. This kind of topology is mainly to solve the problem of insufficient uplink transmission coverage of A-IOT devices, and uses the assisting node to transmit the uplink signal to the network equipment.

[0055] Two scenarios are determined in the related art as follows

[0056] • Deployment scenario 1 with Topology 1 (indoor) (Deployment scenario 1 with topology 1 (indoor))

[0057] • Basestation and coexistence characteristics: Micro-cell, co-site

[0058] • Deployment scenario 2 with Topology 2 and UE as intermediate node, under network control (network device outdoor, tag indoor, their communication relayed through intermediate node)

[0059] • Basestation and coexistence characteristics: Macro-cell, co-site

[0060] • The location of intermediate node is indoor

[0061] 2, A-IOT device type

[0062] i. ~1 μW peak power consumption, has energy storage, initial sampling frequency offset (SFO) up to 10 X ppm, neither DL nor UL amplification in the device. The device’s UL transmission is backscattered on a carrier wave provided externally. / / Least capable (~1 μW peak power consumption, has energy storage, initial sampling frequency offset (SFO) up to 10X ppm, neither DL nor UL amplification in the device. The device’s UL transmission is backscattered on a carrier wave provided externally.)

[0063] ii. ≤ a few hundred μW peak power consumption 1 , has energy storage, initial sampling frequency offset (SFO) up to 10 Xppm, both DL and / or UL amplification in the device. The device’s UL transmission may be generated internally by the device, or be backscattered on a carrier wave provided externally. Best capable (≤ few hundred μW of peak power consumption 1, with energy storage, initial sampling frequency offset (SFO) up to 10X ppm, DL (DownLink) and / or UL (UpLink) amplification in the device. The device’s UL transmission may be generated internally by the device, or be backscattered on a carrier wave provided externally.

[0064] 3. Traffic types: DO-DTT & DT with focus on rUC1 (indoor inventory) and rUC4 (indoor command).

[0065] DO-DTT: Data transmission generated by the terminal device triggered by the downlink signaling of the terminal device

[0066] DT: Downlink signaling of the terminal device

[0067] 4. RFID Query procedure

[0068] Exemplarily, the RFID Query procedure is shown in FIG. 5.

[0069] 1. The interrogator selects a specific group through select signaling.

[0070] 2. The interrogator sends a Query message after a certain time interval (which embodies that the specific group or specific UE is selected and contains Q value).

[0071] 3. The tag randomly selects a value in (0, 2Q-1) in the received value. The tag with the value of 0 sends RN16 to the network device after a certain time interval.

[0072] 4. The network device sends ACK to the tag if RN16 is correctly received.

[0073] 5. The Tag sends tag ID information to the network device.

[0074] 6. The network device sends QueryRep (Query Repetition) information to the terminal device, all terminal devices hold the random number -1. After that, go back to step 3, the network device re-sends Query signaling.

[0075] 7. The terminal device may receive QueryAdjust signaling in the following: Upon receiving a QueryAdjust Tags first update Q, then pick a random value in the range (0, 2Q - 1), inclusive, and load this value into their slot counter. If a Tag, in response to the QueryAdjust, loads its slot counter with zero, then its reply to a QueryAdjust shall be shown in Table 6.35 using the immediate reply type specified in 6.3.1.6.1; otherwise, the Tag shall remain silent. A Tag shall respond to a QueryAdjust only if it received a prior Query.

[0076] 8. A Tag in arbitrate shall decrement its slot counter every time it receives a QueryRep command (see 6.3.2.12.2.3) whose session parameter matches the session for the inventory round currently in progress, and it shall transition to the reply state and backscatter an RN16 when its slot counter reaches 0000h.

[0077] 5. The necessity of intermediate terminal reselection under topology 2

[0078] If the communication frequency bands between different Intermediate UEs and tags are different, and the tag can only listen to data communication on one communication frequency band at a certain moment due to the influence of filter performance and the like, when the communication quality between the tag and the currently camped terminal is too poor, the tag should attempt to switch to the frequency band where the other Intermediate UE may be located to attempt to receive communication signals.

[0079] 6. 5G NR cell selection and reselection

[0080] 1. Cell selection

[0081] 1. Cell measurement

[0082] The NR system has the concept of multiple beams, so the measurement quantity of multiple beams needs to be measured, and only the beam measurement quantity exceeding the threshold will be used for the final measurement quantity calculation.

[0083] For multi-beam cell reselection, including reselection from E-UTRA (Evolved UMTS Terrestrial Radio Access Network) to NR, the cell channel measurement is derived from the SSB (Synchronization Signaling Block) beam:

[0084] • If SIB (System Information Block) 2 / SIB4 does not configure the nrofSS- BlocksToAverage parameter, or SIB2 / SIB4 does not configure the absThreshSS- BlocksConsolidation parameter, or the highest beam measurement is less than or equal to absThreshSS-BlocksConsolidation. Then the cell measurement is the highest beam measurement, each beam measurement is defined in 38.215.

[0085] • Otherwise, the cell measurement is the linear average of the nrofSS-BlocksToAverage highest beam measurement powers above the threshold absThreshSS-BlocksConsolidation.

[0086] 2. S criterion

[0087] The cell selection needs to satisfy the S criterion:

[0088] Srxlev > 0 AND Squal > 0

[0089] Srxlev = Qrxlevmeas - (Qrxlevmin + Qrxlevminoffset) - Pcompensation - Qoffsettemp

[0090] Squal = Qqualmeas - (Qqualmin + Qqualminoffset) - Qoffsettemp

[0091] Where Srxlev is the Cell selection RX level value (dB), Squal is the Cell selection quality value (dB), Qoffsettemp is the Offset temporarily applied to a cell (dB).

[0092] The temporary additional offset connEstFailOffset is defined in SIB1. If the information element is not present in SIB1, Qoffsettemp is considered to be infinity. If SIB1 is configured with connEstFailureControl information element and T300 has expired a consecutive connEstFailCount times on the same cell, connEstFailOffset is used as Qoffsettemp for a period as indicated by connEstFailOffsetValidity. T300 is defined as the time from the UE sending RRCSetupRequest until receiving RRCSetup or RRCReject.

[0093] connEstFailOffset:

[0094] 1> if the field is absent, the value of infinity shall be used for "Qoffsettemp";

[0095] 2> if the T300 has expired a consecutive connEstFailCount times on the same cell for which connEstFailureControl is included in SIB1;

[0096] 3> for a period as indicated by connEstFailOffsetValidity;

[0097] 4> use connEstFailOffset for the parameter Qoffsettemp for the concerned cell when performing cell selection and reselection (use connEstFailOffset for the parameter Qoffsettemp for the concerned cell when performing cell selection and reselection according to TS 38.304

[0020] and TS 36.304

[0027] ).

[0098] Next, the meanings of the above parameters are explained. Among them, Qrxlevmeas is Measured cell RX level value (RSRP) (measured cell reception level value), and Qqualmeas is Measured cell quality value (RSRQ) (measured cell quality value).

[0099] Qrxlevmin:

[0100] Minimum required RX level in the cell (dBm). If the UE supports SUL frequency for this cell, Qrxlevmin is obtained from q-RxLevMinSUL, if present, in SIB1, SIB2 and SIB4, additionally, if QrxlevminoffsetcellSUL is present in SIB3 and SIB4 for the concerned cell, this cell specific offset is added to the corresponding Qrxlevmin to achieve the required minimum RX level in the concerned cell (minimum required RX level in the cell (dBm). If the UE supports SUL frequency for this cell, Qrxlevmin is obtained from q-RxLevMinSUL, if present, in SIB1, SIB2 and SIB4, additionally, if QrxlevminoffsetcellSUL is present in SIB3 and SIB4 for the concerned cell, this cell specific offset is added to the corresponding Qrxlevmin to achieve the required minimum RX level in the concerned cell);

[0101] else Qrxlevmin is obtained from q-RxLevMin in SIB1, SIB2 and SIB4, additionally, if Qrxlevminoffsetcell is present in SIB3 and SIB4 for the concerned cell, this cell specific offset is added to the corresponding Qrxlevmin to achieve the required minimum RX level in the concerned cell.

[0102] Qqualmin:

[0103] Minimum required quality level in the cell (dB). Additionally, if Qqualminoffsetcell is signaled for the concerned cell, this cell specific offset is added to achieve the required minimum quality level in the concerned cell.

[0104] Qrxlevminoffset:

[0105] Offset to the signalled Qrxlevmin taken into account in the Srxlev evaluation as a result of a periodic search for a higher priority PLMN while camped normally in a VPLMN (as a result of a periodic search for a higher priority PLMN while camped normally in a VPLMN, the signalled Qrxlevmin is taken into account in the Srxlev evaluation).

[0106] Qqualminoffset:

[0107] Offset to the signalled Qqualmin taken into account in the Squal evaluation as a result of a periodic search for a higher priority PLMN while camped normally in a VPLMN (as a result of a periodic search for a higher priority PLMN while camped normally in a VPLMN, the signalled Qqualmin is taken into account in the Squal evaluation).

[0108] Pcompensation (pre-compensation):

[0109] For FR1, if the UE supports the additionalPmax in the NR-NS-PmaxList, if present, in SIB1, SIB2 and SIB4 (for FR1, if the UE supports the additionalPmax in the NR-NS-PmaxList, if present, in SIB1, SIB2 and SIB4):

[0110] max(PEMAX1 - PPowerClass, 0) - (min(PEMAX2, PPowerClass) - min(PEMAX1, PPowerClass)) (dB)

[0111] else:

[0112] max(PEMAX1 - PPowerClass, 0) (dB)

[0113] For FR2, Pcompensation is set to 0

[0114] PEMAX1, PEMAX2:

[0115] Maximum TX power level of a UE may use when transmitting on the uplink in the cell (dBm) defined as PEMAX. If UE supports SUL frequency for this cell, PEMAX1 and PEMAX2 are obtained from the p-Max for SUL in SIB1 and NR-NS-PmaxList for SUL respectively in SIB1, SIB2 and SIB4, else PEMAX1 and PEMAX2 are obtained from the p-Max and NR-NS-PmaxList respectively in SIB1, SIB2 and SIB4 for normal UL

[0116] PPowerClass:

[0117] Maximum RF output power of the UE (dBm) according to the UE power class

[0118] Two, cell reselection

[0119] 1. Re-selection priority

[0120] Different NR frequency or inter-system frequency priority can come from SIB, RRCRelease or inter-system re-selection. If there is no re-selection priority configured in SIB for inter-frequency, UE will not perform cell re-selection measurement. If dedicated signaling configures frequency priority, UE will ignore all priority from SIB.

[0121] If UE is in camped on any cell state (unsuccessfully registered, only acceptable cell), UE will only use the priority configured by current cell SIB, and reserve the priority configured by dedicated signaling and RRCRelease signaling deprioritisation information element.

[0122] When UE is in camped normally state (successfully registered, normally camped), there is no priority for current frequency, and inter-frequency is configured with priority, UE considers the current frequency as the lowest priority.

[0123] 1.1. Action of deprioritisationReq

[0124] When UE receives RRCRelease message carrying deprioritisationReq information element, UE considers the current frequency and the frequency or the entire NR system frequency priority received by deprioritisationReq information element in RRCRelease signaling before stored as the lowest, and the duration deprioritisationTimer is T325. The format of deprioritisationReq is as follows:

[0125] deprioritisationReq SEQUENCE{

[0126] deprioritisationType ENUMERATED{frequency, nr},

[0127] deprioritisationTimer ENUMERATED{min5, min10, min15, min30}

[0128] 1.2. Priority provided by dedicated signaling

[0129] The RRCRelease message can carry the frequency point priority CellReselectionPriorities, and before the T320 timeout, the UE in RRC_IDLE state should use the frequency point priority configured in the dedicated signaling. The UE deletes the priority provided by the dedicated signaling in the following cases:

[0130] - The UE enters another RRC state.

[0131] - The dedicated priority validity timer T320 times out.

[0132] - The UE receives the RRCRelease message without the cellReselectionPriorities information element

[0133] - NAS indicates PLMN selection or SNPN selection

[0134] Exemplarily, the format of the dedicated signaling is as shown below:

[0135] 1.3, CellReselectionSubPriority

[0136] The frequency point priority information of SIB2, SIB4, SIB5 and RRCRelease message is added with the parameter CellReselectionSubPriority, and CellReselectionSubPriority is added to cellReselectionPriority to calculate the absolute priority of the frequency point.

[0137] CellReselectionSubPriority:

[0138] The IE CellReselectionSubPriority indicates a fractional value to be added to the value of cellReselectionPriority to obtain the absolute priority of the concerned carrier frequency for E-UTRA and NR. Value oDot2 corresponds to 0.2, value oDot4 corresponds to 0.4 and so on (IE CellReselectionSubPriority indicates a fractional value to be added to the value of cellReselectionPriority to obtain the absolute priority of the concerned carrier frequency for E-UTRA and NR. Value oDot2 corresponds to 0.2, value oDot4 corresponds to 0.4 and so on).

[0139] CellReselectionSubPriority information element (CellReselectionSubPriority information element is as follows):

[0140] CellReselectionSubPriority ::= ENUMERATED { oDot2, oDot4, oDot6, oDot8}

[0141] 2. Cell reselection measurement criteria

[0142] Cell reselection UE measurement criteria are as follows:

[0143] If the current camped cell meets Srxlev > SIntraSearchP and Squal > SIntraSearchQ, no intra-frequency cell measurement is performed. Otherwise, intra-frequency cell measurement is performed.

[0144] For inter-frequency or inter-system frequencies in SIB and configured with frequency priority, the following rules are used:

[0145] - For high priority inter-frequency frequencies, measurements are performed according to 38.133.

[0146] - For same priority or low priority inter-frequency, and low priority inter-system frequencies:

[0147] - Do not perform inter-frequency or inter-RAT measurements if Srxlev > SnonIntraSearchP and Squal > SnonIntraSearchQ.

[0148] - Otherwise perform inter-frequency or inter-RAT measurements according to 38.133.

[0149] 3. Intra-frequency and inter-frequency cell reselection with same priority

[0150] Rs = Qmeas,s + Qhyst - Qoffsettemp

[0151] Rn = Qmeas,n - Qoffset - Qoffsettemp

[0152] The ranking criterion Rs for the serving cell and Rn for the neighbor cell ranking criterion are defined by:

[0153] Qmeas: the measured RSRP at cell reselection.

[0154] Qoffset: Qoffsets,n if configured for intra-frequency cells, otherwise 0. Qoffsets,n + Qoffsetfrequency if configured for inter-frequency cells, otherwise Qoffsetfrequency.

[0155] A new cell is only selected if the following conditions are met:

[0156] Treselection RAT The new cell meets the cell reselection criteria for Treselection;

[0157] The UE has been camped on the current cell for more than 1 second.

[0158] If the rangeToBestCell parameter is not configured, the UE shall reselect to the highest ranked cell.

[0159] If the rangeToBestCell parameter is configured, the UE shall select the cell with the most beams above a given threshold among the highest rangeToBestCell cells ranked according to the R criterion. If there are multiple such cells (same number of beams above the threshold), the highest ranked cell is selected. The threshold is absThreshSS-BlocksConsolidation.

[0160] If the rangeToBestCell parameter is configured but the absThreshSS-BlocksConsolidation parameter is not configured, the UE considers each cell of the frequency to have one beam above the threshold.

[0161] 4. Inter-frequency cell reselection

[0162] High priority cell reselection:

[0163] If the SIB message contains threshServingLowQ, reselect to a high priority inter-frequency or inter-RAT frequency when the following conditions are met:

[0164] Squal>Thresh X,HighQ Duration Treselection RAT ;

[0165] The UE has been camped on the current cell for more than 1 second.

[0166] Otherwise, reselect to a high priority inter-frequency or inter-RAT frequency when the following conditions are met:

[0167] 1. Srxlev>Thresh X,HighP Duration Treselection RAT The cell of the NR or EUTRAN RAT / frequency with higher priority meets Squal>Thresh RAT for the time interval Treselection X，HighQ ;

[0168] 2. The UE has been camped on the current cell for more than 1 second.

[0169] Low priority inter-frequency cell reselection:

[0170] If the SIB message contains threshServingLowQ, reselect to a low priority inter-frequency or inter-RAT frequency when the following conditions are met:

[0171] • The serving cell meets Squal<ThreshServing,LowQ and the inter-frequency or inter-RAT cell meets

[0172] Squal>Thresh X,LowQ for the time interval Treselection RAT ;

[0173] • The UE has been camped on the current cell for more than 1 second.

[0174] Otherwise, reselect to a low priority inter-frequency or inter-RAT frequency when the following conditions are met:

[0175] • Treselection RAT The serving cell meets Srxlev < ThreshServing, LowP and the inter-frequency or inter-RAT cell meets Srxlev > Thresh X,LowP

[0176] • The UE is camped on the current cell for more than 1 second.

[0177] For tags under the coverage of topology 2, if the wireless signal propagation environment between the tag and the intermediate UE of the current camped frequency band becomes poor, it may cause the tag to fail to correctly receive the signal. In this case, if the tag does not transfer the filter to other frequency bands to try to receive the signal of other intermediate UEs, the tag may fail to communicate with the network.

[0178] Please refer to FIG. 6, which shows a flowchart of a measurement method provided by an embodiment of the present application, the method being performed by an A-IOT device. The method includes at least one of the following steps 610-620.

[0179] Step 610, the A-IOT device receives a first reference signal and N second reference signals, the first reference signal being used to measure the communication quality of the A-IOT device at a first frequency, the i-th second reference signal of the N second reference signals being used to measure the communication quality of the A-IOT device at an i-th frequency, the first frequency being the frequency at which the A-IOT device camps, N being a positive integer, and i being a positive integer less than or equal to N.

[0180] In some embodiments, the terminal device transmits the first reference signal. In some embodiments, the terminal device transmits the first reference signal at the first frequency. In some embodiments, the A-IOT device receives the first reference signal at the first frequency. In some embodiments, the A-IOT device has a communication connection with the terminal device. In some embodiments, the A-IOT device communicates with the terminal device at the first frequency.

[0181] In some embodiments, the A-IOT device receives the second reference signal at N second frequencies. In some embodiments, the second frequencies can be the same as or different from the first frequency, which is not limited in the present application.

[0182] ​In some embodiments, the terminal device sending the second reference signal can or can not be the terminal device sending the first reference signal, which is not limited in the present application. For the sake of distinction, in the following embodiments, the terminal device sending the first reference signal is referred to as the first terminal device, and the terminal device not sending the first reference signal is referred to as the second terminal device. It should be noted that the terminal device in the embodiments of the present application refers to the first terminal device.

[0183] In some embodiments, the first terminal device sends the second reference signal on M second frequencies respectively, the second reference signal on the jth frequency of the M second frequencies is used to measure the communication quality of the A-IOT device on the jth frequency, M is a positive integer, and j is a positive integer less than or equal to M. In some embodiments, M can be a positive integer less than or equal to N. In some embodiments, the A-IOT device receives the N second reference signals on the N second frequencies respectively.

[0184] In some embodiments, the A-IOT device can receive the second reference signal from one second terminal device or from multiple second terminal devices, which is not limited in the present application. In some embodiments, one second terminal device can send the second reference signal on one frequency or on multiple frequencies, which is not limited in the present application.

[0185] For example, as shown in FIG. 7, the A-IOT device 710 has a communication connection with the first terminal device 720. The A-IOT device 710 receives the first reference signal 721 sent by the first terminal device 720 and at least one of the following second reference signals: the second reference signal 722 sent by the first terminal device 720, the second reference signal 731 sent by the second terminal device 730, the second reference signal 732 sent by the second terminal device 730, the second reference signal 741 sent by the second terminal device 740, and the second reference signal 742 sent by the second terminal device 740.

[0186] In some embodiments, if the first terminal device sends the second reference signal on a second frequency, the second frequency is the same as the first frequency, the direction of the beam where the second frequency is located is different from the direction of the beam where the first frequency is located.

[0187] In some embodiments, the first reference signal is sent together with a first message, and the first message is used for communication with the A-IOT device. For example, the first message can be used to carry command information sent by the terminal device to the A-IOT device, or can be used to carry data information sent by the terminal device to the A-IOT device.

[0188] In some embodiments, the first reference signal is periodic. Illustratively, the first terminal device sends the first reference signal to the A-IOT device every interval T, where T is a positive number. In some embodiments, T can be agreed by protocol, predefined or preconfigured, or determined by the terminal device itself, which is not limited in the present application.

[0189] In some embodiments, the first reference signal is aperiodic. Illustratively, the first terminal device sends the first reference signal together with the first message when the first terminal device needs to send the first message to the A-IOT device.

[0190] In step 620, the A-IOT device measures the first reference signal to obtain a measurement result of the first reference signal, and measures the N second reference signals to obtain N measurement results respectively corresponding to the N second reference signals.

[0191] In some embodiments, the A-IOT device measures the first reference signal to obtain a measurement result of the first reference signal. In some embodiments, the measurement result of the first reference signal can reflect the communication quality between the A-IOT device and the terminal device at the first frequency.

[0192] In some embodiments, the A-IOT device respectively measures the N second reference signals to obtain N measurement results respectively corresponding to the N second reference signals. The N measurement results respectively corresponding to the N second reference signals can reflect the communication quality of the A-IOT device at the second frequency.

[0193] In some embodiments, the measurement result comprises at least one of: RSRQ (Reference Signal Receiving Quality), RSRP (Reference Signal Receiving Power), SINR (Signal to Interference plus Noise Ratio). RSRP is the linear average of the power contribution (in units of w) of resource elements that carry reference signals on the measurement frequency (the protocol specifies that RSRP refers to the energy per RE, but it is not possible to insert RS in each RE, so the average is calculated after inserting a few in the RB). Simply, RSRP can be considered as the power of each subcarrier. RSSI (Reference Singal Strength Indicator) refers to the total power in the received bandwidth, including useful signals, interference and noise. The reference point of the measurement is the antenna port of the UE. RSRQ is defined as RSRQ = N*RSRP / (E-UTRA carrier RSSI). Where N is the number of RBs in the E-UTRA carrier RSSI measurement bandwidth. The protocol specifies that RSRQ is measured per RB, which is different from the specification of RSRP per RE. From the formula, it can be inferred that the logarithm of RSRQ is generally negative. SINR is the ratio of the strength of the received useful signal to the strength of the received interference signal (noise and interference); it can be simply understood as "signal-to-noise ratio".

[0194] In some embodiments, the A-IOT device can determine whether to shift to other frequencies for communication based on the measurement result of the first reference signal and the measurement results of the N second reference signals.

[0195] In some embodiments, the A-IOT device can also send a reference signal to the terminal device, and the terminal device can evaluate the communication quality of the first frequency.

[0196] In some embodiments, the method further comprises the following step 630.

[0197] Step 630, the A-IOT device sends a third reference signal in a backscatter mode, and the third reference signal is used to measure the communication quality of the A-IOT device on the first frequency.

[0198] Correspondingly, the terminal device receives the third reference signal, measures the third reference signal, and obtains a measurement result of the third reference signal.

[0199] The technical scheme provided by the embodiments of the present application enables the A-IOT device to receive the first reference signal and the at least one second reference signal, and to measure the first reference signal and the at least one second reference signal, thereby obtaining the measurement result of the first reference signal and the measurement result corresponding to each of the at least one second reference signal, so that the A-IOT device can evaluate the communication quality on different frequencies, and a method for the A-IOT device to switch to another frequency for communication is provided, thereby ensuring the stability of the communication system.

[0200] In some embodiments, the second frequency can be the same as or different from the first frequency. In this regard, the embodiments of the present application provide exemplary embodiments.

[0201] Example 1: the second frequency is different from the first frequency

[0202] In some embodiments, the frequencies of the N second reference signals are all different from the first frequency.

[0203] In some embodiments, the above step 620 can be implemented as the following step 621.

[0204] Step 621: in the case where the first condition is met, measuring the N second reference signals to obtain the measurement result corresponding to each of the N second reference signals.

[0205] In some embodiments, the first condition includes at least one of the following:

[0206] The priority of the frequency where at least one of the N second reference signals is located is higher than the priority of the first frequency;

[0207] The A-IOT device receives the first indication information, and the first indication information is used to instruct the A-IOT device to measure the N second reference signals;

[0208] The first parameter corresponding to the first reference signal is less than a first threshold, and the first parameter is used to measure the received power of the reference signal;

[0209] The second parameter corresponding to the first reference signal is less than a second threshold, and the second parameter is used to measure the received quality of the reference signal.

[0210] In some embodiments, if the A-IOT device learns that the priority of the frequency where at least one of the N second reference signals is located is higher than the priority of the first frequency, the A-IOT device measures the N second reference signals. In some embodiments, whether there is a second reference signal in the N second reference signals whose priority of the frequency where the second reference signal is located is higher than the priority of the first frequency can be predefined or preconfigured, or can be indicated by the terminal device, which is not limited in the present application.

[0211] In some embodiments, the A-IOT device receives the first indication information, and the A-IOT device measures the N second reference signals. Correspondingly, the terminal device sends the first indication information. In some embodiments, the first indication information can be implicit indication that the A-IOT device measures the N second reference signals. Illustratively, the first indication information is used to indicate that the priority of the frequency where at least one of the N second reference signals is located is higher than the priority of the first frequency. In some embodiments, the first indication information can be explicit indication that the A-IOT device measures the N second reference signals. Illustratively, the first indication information includes at least one bit, which is used to indicate that the A-IOT device measures the N second reference signals.

[0212] In some embodiments, the terminal device sends the first indication information to the A-IOT device.

[0213] In some embodiments, the terminal device sends the first indication information in a case where the priority of the frequency where at least one of the N second reference signals is located is higher than the priority of the first frequency.

[0214] In some embodiments, the terminal device sends the first indication information in a case where the priority of the frequency where the N second reference signals are located is not higher than the priority of the first frequency, and the measurement result of the third reference signal is less than the fifth threshold value.

[0215] In some embodiments, the fifth threshold value can be predefined or preconfigured, or can be determined by the terminal device itself, which is not limited in the present application.

[0216] In some embodiments, the fifth threshold value can include at least one threshold value. In some embodiments, in a case where the fifth threshold value includes multiple threshold values, the measurement result of the third reference signal being less than the fifth threshold value includes at least one of the following cases: the multiple measurement results of the third reference signal are all less than the corresponding threshold values in the fifth threshold value; at least one of the multiple measurement results of the third reference signal is less than the threshold value corresponding to the measurement result in the fifth threshold value. Illustratively, the measurement result of the third reference signal includes RSRQ and RSRP, and the fifth threshold value includes the threshold value corresponding to RSRQ and the threshold value corresponding to RSRP. The measurement result of the third reference signal being less than the fifth threshold value can mean that RSRP is less than the threshold value corresponding to RSRP, and RSRQ is less than the threshold value corresponding to RSRQ; or RSRP is less than the threshold value corresponding to RSRP, or RSRQ is less than the threshold value corresponding to RSRQ.

[0217] In some embodiments, the terminal device sends the first indication information in a case where the measurement result of the third reference signal is less than the fifth threshold value.

[0218] In some embodiments, the first parameter corresponding to the first reference signal is less than a first threshold, and the A-IOT device measures the N second reference signals.

[0219] In some embodiments, the second parameter corresponding to the first reference signal is less than a second threshold, and the A-IOT device measures the N second reference signals.

[0220] In some embodiments, the first threshold and the second threshold can be predefined or preconfigured, or can be determined by the terminal device itself, which is not limited in the present application.

[0221] In some embodiments, the first parameter and the second parameter of the first reference signal can refer to S criteria. Exemplarily, the first parameter of the first reference signal is Srxlev, and the second parameter is Squal.

[0222] In some embodiments, if the priority of the frequency where the second reference signal is located is not higher than the priority of the first frequency, the A-IOT device does not measure the N second reference signals. In some embodiments, if the first parameter corresponding to the first reference signal is greater than the first threshold, and / or the second parameter corresponding to the first reference signal is greater than the second threshold, the A-IOT device does not measure the N second reference signals.

[0223] Please refer to FIG. 8, which shows a flowchart of a measurement method provided by another embodiment of the present application.

[0224] In the case where there is no second frequency with a priority higher than that of the first frequency, if the A-IOT device finds that the first reference signal quality (RSRP) of the terminal device is poor, or the terminal device finds that the third reference signal quality of the A-IOT device transmitted in the backscattering mode is poor, the A-IOT device measures the N second reference signals and reselects the first frequency according to the measurement results respectively corresponding to the N second reference signals.

[0225] Please refer to FIG. 9, which shows a flowchart of a measurement method provided by another embodiment of the present application.

[0226] In the case where the terminal device knows that there is a second frequency with a priority higher than that of the first frequency, and sends the first indication information to the A-IOT device, or the A-IOT device itself knows that there is a second frequency with a priority higher than that of the first frequency, the A-IOT device measures the N second reference signals and reselects the first frequency according to the measurement results respectively corresponding to the N second reference signals.

[0227] Example II, the second frequency is the same as the first frequency

[0228] In some embodiments, the N second reference signals are located at the same frequency as the first frequency.

[0229] In some embodiments, the step 620 can be implemented as a step 622.

[0230] At step 622, the A-IOT device measures the N second reference signals to obtain N measurement results corresponding to the N second reference signals respectively, in a case where a second condition is met.

[0231] In some embodiments, the second condition comprises at least one of:

[0232] The first parameter corresponding to the first reference signal is less than a third threshold, and the first parameter is used to measure the received power of the first reference signal.

[0233] The second parameter corresponding to the first reference signal is less than a fourth threshold, and the second parameter is used to measure the received quality of the first reference signal.

[0234] The A-IOT device receives second indication information, and the second indication information is used to instruct the A-IOT device to measure the N second reference signals.

[0235] In some embodiments, the first parameter corresponding to the first reference signal is less than the third threshold, and the A-IOT device measures the N second reference signals.

[0236] In some embodiments, the first parameter corresponding to the first reference signal is less than the fourth threshold, and the A-IOT device measures the N second reference signals.

[0237] In some embodiments, the third threshold and the fourth threshold can be predefined or preconfigured, or can be determined by the terminal device itself. In some embodiments, the third threshold can be the same as the first threshold, or can be different from the first threshold, which is not limited in the present application. In some embodiments, the fourth threshold can be the same as the second threshold, or can be different from the second threshold, which is not limited in the present application.

[0238] In some embodiments, if the A-IOT device receives the second indication information, the A-IOT device measures the N second reference signals. In some embodiments, the second indication information can implicitly instruct the A-IOT device to measure the N second reference signals. For example, the second indication information is used to indicate that the N second reference signals are located at the same frequency as the first frequency. In some embodiments, the second indication information can explicitly instruct the A-IOT device to measure the N second reference signals. For example, the second indication information comprises at least one bit, and the at least one bit is used to instruct the A-IOT device to measure the N second reference signals.

[0239] In some embodiments, the terminal device sends the second indication information in a case where the measurement result of the third reference signal is less than the sixth threshold value, the second indication information being used to indicate that the A-IOT device measures the N second reference signals.

[0240] In some embodiments, the sixth threshold value can include at least one threshold value. In a case where a plurality of threshold values are included in the sixth threshold value, the measurement result of the third reference signal being less than the sixth threshold value includes at least one of the following: the plurality of measurement results of the third reference signal are all less than the corresponding threshold value in the sixth threshold value; at least one of the plurality of measurement results of the third reference signal is less than the threshold value corresponding to the measurement result in the sixth threshold value. Exemplarily, the measurement result of the third reference signal includes RSRQ and RSRP, and the sixth threshold value includes the threshold value corresponding to RSRQ and the threshold value corresponding to RSRP. The measurement result of the third reference signal being less than the sixth threshold value can be that RSRP is less than the threshold value corresponding to RSRP and RSRQ is less than the threshold value corresponding to RSRQ; or RSRP is less than the threshold value corresponding to RSRP or RSRQ is less than the threshold value corresponding to RSRQ.

[0241] In some embodiments, the sixth threshold value can be predefined or preconfigured, or can be determined by the terminal device itself. In some embodiments, the sixth threshold value can be the same as the fifth threshold value, or can be different from the fifth threshold value, which is not limited in the present application.

[0242] In some embodiments, the above-mentioned example one and example two respectively take the case that the frequencies of the N second reference signals are different from the first frequency and the case that the frequencies of the N second reference signals are the same as the first frequency as examples to illustrate the processing manner of the second reference signals in the two different cases. However, in actual cases, there can be cases that the frequencies of some of the N second reference signals are the same as the first frequency and the frequencies of some of the N second reference signals are different from the first frequency. For example, N=3, the frequency of the second reference signal 1 is the same as the first frequency, and the frequencies of the second reference signal 2 and the second reference signal 3 are different from the first frequency. In this case, the A-IOT device only needs to classify the N second reference signals according to the frequencies of the N second reference signals, and then process them according to the methods in the above-mentioned example one and example two. For example, the N second reference signals can be classified into two categories according to the frequencies of the N second reference signals, one category has N1 second reference signals, the frequencies of the N1 second reference signals are different from the first frequency, and the other category has N2 second reference signals, the frequencies of the N2 second reference signals are the same as the first frequency, N1 and N2 are integers less than or equal to N, and N1+N2=N. Then, the N1 second reference signals can be processed according to the scheme of example one, and the N2 second reference signals can be processed according to the scheme of example two.

[0243] Through the above-mentioned method, the A-IOT device can determine whether to measure the received second reference signal, thereby reducing the energy consumption of the A-IOT device caused by unnecessary measurement.

[0244] In some embodiments, if the communication quality on the first frequency cannot meet the communication requirement between the A-IOT device and the terminal device, the A-IOT device can switch to another frequency to communicate.

[0245] In some embodiments, the method further includes the following step 640.

[0246] Step 640, in the case that the third condition is met, the A-IOT device reselects the first frequency.

[0247] In some embodiments, in the case that the third condition is met, the A-IOT device reselects the first frequency from the frequencies of the measured second reference signals.

[0248] In some embodiments, the third condition includes at least one of the following:

[0249] The A-IOT device receives third indication information, and the third indication information is used to instruct the A-IOT device to perform the reselection of the first frequency;

[0250] The measurement result of the first reference signal is less than a fifth threshold value.

[0251] The A-IOT device detects an Au interface RLF (Radio Link Failure).

[0252] In some embodiments, if the A-IOT device receives third indication information, the A-IOT device reselects the first frequency. Accordingly, the terminal device sends the third indication information. In some embodiments, the third indication information can be used to indicate the first frequency to which the A-IOT device needs to reselect. Illustratively, the first frequency is frequency band 1, and the third indication information is used to indicate that the A-IOT device reselects the first frequency to frequency band 2. In some embodiments, the third indication information is used to indicate that the A-IOT device reselects the first frequency, and after receiving the first indication information, the A-IOT device selects one of the frequencies where the measured second reference signals are located as the reselected first frequency. Illustratively, the A-IOT device determines the frequency where the second reference signal with the best communication quality among the measured second reference signals is located as the reselected first frequency.

[0253] In some embodiments, the terminal device sends the third indication information when a fourth condition is met.

[0254] In some embodiments, the fourth condition includes at least one of the following:

[0255] The terminal device experiences a Uu interface radio link failure RLF;

[0256] The terminal device experiences a Uu interface radio resource control RRC connection establishment failure or a Uu interface RRC connection recovery failure;

[0257] The terminal device is not in an RRC connected state;

[0258] The priority of the frequency where the N second reference signals are located is not higher than the priority of the first frequency, and the measurement result of the third reference signal is less than a fifth threshold.

[0259] In some embodiments, if the measurement result of the first reference signal is less than the fifth threshold, it indicates that the communication quality on the first frequency is poor, and therefore the A-IOT device can reselect the first frequency.

[0260] In some embodiments, the A-IOT device is in communication connection with the terminal device through the Au interface, and if the A-IOT device detects that the Au interface experiences an RLF, it indicates that the communication connection between the A-IOT device and the terminal device is disconnected, and therefore the A-IOT device can reselect the first frequency.

[0261] In some embodiments, the terminal device sends the third indication information in a case where the terminal device has an Uu interface RLF. In some embodiments, the terminal device is connected to the network device based on the Uu interface, and if the terminal device detects that the Uu interface has an RLF, it indicates that the communication connection between the terminal device and the network device is disconnected, and the data obtained by the terminal device from the A-IOT device cannot be reported to the network device, so the A-IOT device can be instructed to perform the step of reselecting the first frequency.

[0262] In some embodiments, the terminal device sends the third indication information in a case where the terminal device has an Uu interface RRC (Radio Resource Control) connection establishment failure or Uu interface RRC connection recovery failure. In some embodiments, if the terminal device detects that the Uu interface has an RRC connection establishment failure or RRC connection recovery failure, it indicates that the terminal device cannot establish an RRC connection with the network device. Similarly, the data obtained by the terminal device from the A-IOT device cannot be reported to the network device, so the A-IOT device can be instructed to perform the step of reselecting the first frequency.

[0263] In some embodiments, the terminal device sends the third indication information in a case where the terminal device is not in an RRC connected state. In some embodiments, in a case where the terminal device is in an RRC inactive state or the terminal device is in an RRC idle state, the terminal device does not perform communication transmission with the network device. Similarly, the data obtained by the terminal device from the A-IOT device cannot be reported to the network device, so the A-IOT device can be instructed to perform the step of reselecting the first frequency.

[0264] In some embodiments, the terminal device sends the third indication information in a case where the priority of the frequency on which the N second reference signals are located is not higher than the priority of the first frequency, and the measurement result of the third reference signal is less than the fifth threshold.

[0265] In the above embodiments, it is explained that the A-IOT device has the capability to measure the reference signal. In some embodiments, the A-IOT device can not have the capability to measure the reference signal, and in this case, how does the A-IOT device implement the reselection of the first frequency?

[0266] In some embodiments, the terminal device sends fourth indication information, and the fourth indication information is used to instruct the A-IOT device to camp on a second frequency, and the A-IOT device communicates with the terminal device on the second frequency. It should be noted that the second frequency indicated by the fourth indication information is the same frequency as the first frequency on the same terminal device. The A-IOT device communicates with the terminal device 1 through the first frequency, and after receiving the fourth indication information, the A-IOT device communicates with the terminal device 1 through the second frequency.

[0267] In some embodiments, the terminal device sends fourth indication information in the case that the measurement result of the third reference signal is less than the fifth threshold, the fourth indication information being used to instruct the A-IOT device to camp on the second frequency, and the A-IOT device and the terminal device perform communication transmission on the second frequency.

[0268] In some embodiments, the terminal device randomly selects one second frequency from the at least one second frequency, and instructs the A-IOT device to camp on the second frequency.

[0269] In some embodiments, the terminal device selects one second frequency based on the location information of the A-IOT device, and the second frequency has better communication quality when the A-IOT device communicates with A-IOT devices within a certain range of the A-IOT device. The certain range of the A-IOT device refers to a range centered on the A-IOT device, and the determination manner of the range is not limited in the present application. Exemplarily, the range is a circular range, and the range is a range with the A-IOT device as the center and a radius of r.

[0270] Through the above method, in the case that the communication quality on the first frequency does not meet the demand of the A-IOT device, the A-IOT device can reselect to a new first frequency to ensure the communication transmission of the A-IOT device and improve the stability of the communication system.

[0271] In the above method embodiment, the technical solutions of the present application are introduced and explained only from the perspective of the A-IOT device interacting with the terminal device. The steps performed by the A-IOT device described above can be implemented alone to become a measurement method on the A-IOT device side, and the steps performed by the terminal device described above can be implemented alone to become a measurement method on the terminal device side. In addition, the embodiments provided in the present application can be combined arbitrarily to form new embodiments, which are all within the protection scope of the present application.

[0272] The following is a device embodiment of the present application, which can be used to execute the method embodiments of the present application. For details not disclosed in the device embodiments of the present application, please refer to the method embodiments of the present application.

[0273] Please refer to FIG. 10, which shows a block diagram of a measurement device according to an embodiment of the present application.
