Cell measurement method and communication device

Abstract

The invention provides a cell measurement method and a communication device. The method comprises the following steps that: terminal equipment measures a service cell by using a wake-up circuit; under the condition that the terminal equipment does not measure the neighbor cell, the terminal equipment starts to use a main circuit to measure the neighbor cell according to the cell quality of the service cell and a first threshold value; under the condition that the terminal equipment measures the neighbor cell, the terminal equipment stops using the main circuit to measure the neighbor cell according to the cell quality of the service cell and a second threshold value; wherein the first threshold value is different from the second threshold value. Through the mode, after the terminal equipment introduces the wake-up circuit, whether the main circuit is used for measuring the neighbor cell or not can be determined through the two threshold values, such as the first threshold value and the second threshold value, and the cell measurement performance can be improved. Besides, in some scenes, the operation of starting a main circuit to execute cell measurement can be reduced, and the power consumption benefit of the wake-up circuit to the terminal equipment is improved.

Description

Technical Field

[0001] The present application relates to the field of wireless communications, and more specifically, to a method and a communication device for measuring a cell. Background Art

[0002] The terminal device can receive the wake-up signal through a separate low-power small circuit, such as a wake-up receiver (WUR), and the main receiver can be in a deep sleep state. When the terminal device detects the wake-up signal through the WUR, the terminal device triggers the wake-up of the main receiver. After the main receiver wakes up, the terminal device can perform data transmission through the main receiver. In some scenarios, the terminal device needs to measure cells, such as service cells, neighboring cells, etc. After the introduction of WUR, how the terminal device measures the cell is a question worth considering. Summary of the invention

[0003] The present application provides a cell measurement method and a communication device, which can improve the performance of cell measurement.

[0004] In a first aspect, a method for measuring a cell is provided, which can be performed by a communication device. The communication device can be a device (such as a terminal device), or can be a component of a device (such as a chip or a chip system or a circuit), which is not limited in this application.

[0005] The method may include: measuring a serving cell; when no neighboring cell is measured, starting measurement of the neighboring cell based on the cell quality of the serving cell and a first threshold; when measuring the neighboring cell, stopping measurement of the neighboring cell based on the cell quality of the serving cell and a second threshold; wherein the first threshold and the second threshold are different.

[0006] Based on the above technical solution, two thresholds (i.e., a first threshold and a second threshold) are designed to determine whether to start measuring neighboring cells or whether to stop measuring neighboring cells. Specifically, when a communication device (such as a terminal device or a component of a terminal device) does not measure neighboring cells, such as when the communication device moves from the center of the cell to the edge of the cell, the communication device can compare the first threshold with the cell quality of the serving cell, and determine whether to start measuring neighboring cells based on the comparison result, so that the communication device can perform service cell measurements in a larger range, thereby reducing power consumption caused by cell measurements and achieving energy saving effects. When a communication device (such as a terminal device or a component of a terminal device) measures neighboring cells, such as when the communication device moves from the edge of the cell to the center of the cell, the communication device can compare the second threshold with the cell quality of the serving cell, and determine whether to stop measuring neighboring cells based on the comparison result, so that the influence of interference / noise on the measurement results can be reduced and the ping-pong effect can be avoided.

When the communication device measures the neighboring cell, when the cell quality of the serving cell is greater than or equal to the second threshold, the communication device stops measuring the neighboring cell, otherwise it continues to measure the neighboring cell, which can reduce the influence of interference / noise on the measurement result and avoid the ping-pong effect.

[0172] First combine Figure 1 A communication system applicable to an embodiment of the present application is briefly introduced as follows.

[0173] See also Figure 1 , as an example, Figure 1 FIG. 1 is a schematic diagram of a wireless communication system 100 applicable to an embodiment of the present application.

[0177] To facilitate understanding of the embodiments of the present application, a brief description of the terms involved in the present application is given.

[0178] 1. Paging

[0179] When the terminal device is in an idle state or an inactive state, it can periodically receive paging. As an example, the process of receiving paging by the terminal device includes the following steps.

[0180] 1) The terminal device can calculate a paging frame (PF) and a position of a paging occasion (PO) in the PF according to its own identifier (ID) (UE ID).

[0181] 2) The terminal device monitors a physical downlink control channel (PDCCH) (also called a paging PDCCH) in the PO, where the PDCCH includes downlink control information (DCI) (also called a paging DCI).

[0182] 3) If the terminal device detects the PDCCH, the terminal device receives the physical downlink shared channel (PDSCH) (also known as the paging PDSCH) at the location scheduled by the PDCCH. The paging PDSCH contains a paging message, which may indicate which terminal devices have been paged. As an example, the paging PDSCH contains up to 32 paging records, each of which may contain a UE ID, which is used to indicate which UE has been paged.

[0183] The above description about paging is only an exemplary description and does not limit the protection scope of the embodiments of the present application.

[0184] 2. Wake-up circuit: also called wake-up receiver (WUR) or low-power wake-up receiver (LP-WUR) or wake-up module, can be understood as a separate low-power small circuit, such as the circuit used by the terminal device in the idle state. The low-power small circuit can be implemented using a separate small circuit or chip with a simple structure, and its power consumption is low. It can be understood that the wake-up circuit is only named for distinction, and its specific naming does not limit the scope of protection of this application. For example, without loss of generality, the wake-up circuit can also be described as the first circuit (or first module). The following is uniformly described as a wake-up circuit.

[0185] The signal received by the terminal device using the wake-up circuit can be said to be transmitted on the wake-up link, where the wake-up link represents a connection relationship between the terminal device and the network device. It is a logical concept rather than a physical entity. It can be understood that the wake-up link is only a name for distinction, and its specific name does not limit the scope of protection of this application. For example, without loss of generality, the wake-up link can also be described as the first link. It is uniformly described as the wake-up link below.

[0186] The signal received by the terminal device using the wake-up circuit can be called a wake-up signal (wake up signal / radio, WUS / WUR) or a low power wake-up signal (low power wake up signal, LP-WUS). It can be understood that the wake-up signal is only named for distinction, and its specific naming does not limit the scope of protection of this application. For example, without loss of generality, the wake-up signal can also be called a signal. The following unified description is a wake-up signal.

[0187] 3. Main circuit: also called main receiver (MR) or main module, it can be understood as the circuit used by the terminal device when transmitting data normally, or the circuit used by the terminal device when transmitting data in a connected state. When the terminal device uses the main circuit to transmit data, the power consumption is relatively large. It can be understood that the main circuit is only named for distinction, and its specific naming does not limit the scope of protection of this application. For example, without loss of generality, the main circuit can also be described as the second circuit (or second module). The following unified description is the main circuit.

[0188] The signal received by the terminal device using the main circuit can be said to be transmitted on the main link, where the main link represents a connection relationship between the terminal device and the network device, which is a logical concept rather than a physical entity. It can be understood that the main link is only named for distinction, and its specific naming does not limit the scope of protection of this application. For example, without loss of generality, the main link can also be described as the second link. The following unified description is the main link.

[0189] In the following, for the purpose of distinction, the signal transmitted by the terminal device using the main circuit is recorded as a data signal.

[0190] See also Figure 2 , as an example, Figure 2 It is a schematic diagram of the main circuit and wake-up circuit.

[0191] like Figure 2 As shown, the terminal device can receive (or detect) a wake-up signal through a wake-up circuit, and the terminal device can receive a data signal through the main circuit. Assume that the terminal device receives a wake-up signal through a wake-up circuit. If the terminal device does not detect a wake-up signal, the wake-up circuit continues to be used to receive the wake-up signal, and the main circuit can be in an off state (or a sleep state); if the terminal device detects a wake-up signal, the wake-up of the main circuit is triggered, that is, the main circuit is in / switched to an on state (or a working state, or an active state). After the main circuit is turned on, the terminal device can transmit data signals through the main circuit.

[0192] 4. On-off key (OOK) modulation: Information is modulated by whether the signal is sent or not, and the corresponding wake-up circuit can use the envelope detection method to receive the signal. OOK modulation technology can be demodulated with a receiver with very low complexity, so the low power consumption goal of the wake-up circuit can be achieved. In order to ensure power consumption benefits, the wake-up signal can use OOK modulation. It can be understood that the wake-up signal can also use other modulation methods, such as frequency shift keying (FSK) modulation, which is not limited.

[0193] When the signal is modulated using OOK, each bit (ie, the encoded bit) may correspond to a symbol. Equivalently, a symbol may also be called a chip, or other names, which are not limited here.

[0194] For example, when a bit is "1", a signal is sent within the symbol length (i.e., the signal transmission power within the symbol length is not 0); when a bit is "0", no signal is sent within the symbol length (i.e., the signal transmission power within the symbol length is 0). Alternatively, it can be understood that in OOK modulation, if energy is sent, it represents "1", and if no energy is sent, it represents "0".

[0195] For another example, when the bit is "0", a signal is sent within the symbol length (i.e., the signal transmission power within the symbol length is not 0); when the bit is "1", no signal is sent within the symbol length (i.e., the signal transmission power within the symbol length is 0). Alternatively, it can be understood that in OOK modulation, if energy is sent, it represents "0", and if no energy is sent, it represents "1".

[0196] In the following, for the convenience of description, an example is mainly taken as follows: when a bit is "1", a signal is sent within the symbol length; when a bit is "0", no signal is sent within the symbol length.

[0197] In addition, for the convenience of description, if a signal is sent within a symbol, the signal is recorded as an ON signal; if no signal is sent within a symbol, the signal is recorded as an OFF signal. For example, when the bit is "1", a signal is sent within the symbol length; when the bit is "0", no signal is sent within the symbol length, the ON signal indicates that the information bit is "1", and the OFF signal indicates that the information bit is "0".

[0198] In addition, the OOK symbol mentioned below means a symbol obtained by OOK modulation. The OOK symbol can be, for example, an ON signal, or it can also be an OFF signal. For example, if the information bit is "1", the OOK symbol obtained by OOK modulation is an ON signal, and if the information bit is "0", the OOK symbol obtained by OOK modulation is an OFF signal. The OOK symbol can also be called an OOK signal. For uniformity, the OOK symbol is used in the following description.

[0199] See also Figure 3 , as an example, Figure 3 This is a waveform diagram of the signal when it uses OOK modulation.

[0200] As an example, assume that when the bit is "1", a signal is sent within the OOK symbol length; when the bit is "0", no signal is sent within the OOK symbol length, so Figure 3 The waveform shown can represent the four bits "0100", that is, the first one is an OFF signal, the second one is an ON signal, and the third and fourth ones are both OFF signals. Figure 3 As shown, communication systems generally use a certain frequency for transmission, and the transmitted signal needs to be modulated on a carrier. At the receiving end, the receiving end detects the envelope (or energy) of the received signal and determines whether the OOK symbol corresponds to a bit "0" or a bit "1", thereby completing demodulation.

[0201] After the signal passes through the channel, it may be distorted due to the influence of the channel state, etc. Figure 3 Take the OOK modulation waveform shown as an example. Figure 3 The waveform shown may become as follows at the receiving end: Figure 4 The waveform shown.

[0202] See also Figure 4 , as an example, Figure 4 It is a schematic diagram of the waveform of the signal after it passes through the channel. In order to determine whether the signal corresponds to bit "0" or bit "1", the terminal device can compare the received signal level value with a threshold (the threshold is as follows Figure 4 ). For example, if the signal level value received by the terminal device is greater than the threshold, it means that the signal corresponds to bit "1"; if the signal level value received by the terminal device is less than the threshold, it means that the signal corresponds to bit "0". However, it is difficult to set the threshold. For example, if the threshold is not selected appropriately, it may cause demodulation errors. In order to solve this problem, one possible way is to use Manchester coding.

[0203] 5. Manchester coding: It is a bi-phase coding that can represent bit "0" or bit "1" by converting the level between high and low. For example, through Manchester coding, the original bit "0" can be encoded as bit "10", and the original bit "1" can be encoded as bit "01". To distinguish, the bits after the original bit encoding, such as bits "10" and "01", can be called coded bits. When sending a signal, the transmitter can use 2 OOK symbols to send 1 bit of original information. If the original bit "0" is encoded as bit "10" and the original bit "1" is encoded as bit "01", the original bit "0" corresponds to an ON signal followed by an OFF signal, and the original bit "1" corresponds to an OFF signal followed by an ON signal. When the receiving end demodulates the Manchester-encoded signal, it can compare the relative size of the signal power (or signal amplitude) in two adjacent OOK symbols. If the signal power (or signal amplitude) in the previous OOK symbol is greater than the signal power (or signal amplitude) in the next OOK symbol, the received information bit is considered to be "0", otherwise it is considered to be "1". In this way, it is possible to avoid selecting an absolute threshold for making a decision.

[0204] It can be understood that the above is an exemplary description of the original bit "0" being encoded as bit "10" and the original bit "1" being encoded as bit "01", and this is not limiting. For example, the original bit "0" is encoded as bit "01", and the original bit "1" is encoded as bit "10".

[0205] As an example, the signal may be generated based on an orthogonal frequency division multiplexing (OFDM) transmitter, that is, the signal may be modulated using an OFDM transmitter.

[0206] One possible way is to transmit an OOK symbol within the length of an OFDM symbol, or in other words, an OOK symbol occupies one OFDM symbol. For example, if an ON signal is to be sent within the length of an OOK symbol, the transmitter can send a certain signal so that the contour of the signal within the length of the OOK symbol is as square as possible; if an OFF signal is to be sent within the length of an OOK symbol, the transmitter can shut down for a time of the length of an OOK symbol.

[0207] See also Figure 5 , as an example, Figure 5 This is a schematic diagram of the waveform of the signal after Manchester encoding. Figure 5 As shown in the figure, the original bits are “0 0 1 0 0 1 0 1 1 0”. Assuming that the original bit “0” is encoded as “10” and the original bit “1” is encoded as “01”, the coded bits after Manchester encoding are “10 10 01 10 10 01 10 01 10”. The waveform is as follows: Figure 5 As shown. The time length corresponding to each coded bit can be considered as the length of an OFDM symbol, that is, an OOK symbol is transmitted within the length of an OFDM symbol, or an OOK symbol occupies one OFDM symbol. When demodulating the signal, the receiving end can compare the relative size of the signal power (or signal amplitude) in two adjacent OOK symbols, and determine the demodulated information bit based on the comparison result.

[0208] Another possible way is to transmit at least two OOK symbols within the length of one OFDM symbol, or at least two OOK symbols occupy one OFDM symbol.

[0209] See also Figure 6 , as an example, Figure 6 This is another schematic diagram of the waveform of the signal after Manchester encoding. Figure 6 As shown in the figure, the original bit is "0 0 0 1". Assuming that the original bit "0" is encoded as "10" and the original bit "1" is encoded as "01", the encoded bits after Manchester encoding are "10 10 10 10 01". The waveform is as follows: Figure 6 As shown. Among them, in an OFDM symbol length ( Figure 6 In the example, 8 OOK symbols are sent within 2192 sampling points, which are ON signal-OFF signal-ON signal-OFF signal-ON signal-OFF signal-OFF signal-ON signal. When the receiving end demodulates the signal, it can compare the relative size of the signal power (or signal amplitude) of two adjacent OOK symbols and determine the demodulated information bits based on the comparison result.

[0210] It can be understood that in the embodiment of the present application, one OOK symbol can be transmitted within the length of one OFDM symbol, or at least two OOK symbols can be transmitted within the length of one OFDM symbol, and there is no limitation on this. In addition, whether one OOK symbol or at least two OOK symbols are transmitted within the length of one OFDM symbol, it is not limited to this Manchester encoding.

[0211] 6. Frequency Shift Keying (FSK) Modulation: It is a modulation technique that modulates information onto the carrier frequency.

[0212] See Figure 7 , for example, Figure 7 is a schematic diagram of the waveform of the signal after FSK modulation. As Figure 7 shown, when the wake-up signal uses FSK modulation, different information uses different frequency resources. For example, 2FSK carries 1-bit information. When the information bit is 0, the information is sent on the frequency resource f0 and not sent on the frequency resource f1; when the information bit is 1, the information is sent on the frequency resource f1 and not sent on the frequency resource f0. Assuming f0 < f1, the waveform of the FSK signal with the information 0101 is as Figure 7 shown. In the first and third symbols, the frequency of the signal is lower, and in the second and fourth symbols, the frequency of the signal is higher. When the receiving end demodulates the signal, it can compare the power levels on f0 and f1 to determine whether the transmitted information is 0 or 1.

[0213] It can be understood that the above is for illustrative purposes and is not limited thereto. For example, FSK can also support higher modulation orders to carry more information. For example, 4FSK can carry 2-bit information. When the information bit is 00, the information can be sent on the frequency resource f0 and not sent on the frequency resources f1, f2, f3; when the information bit is 01, the information can be sent on the frequency resource f1 and not sent on the frequency resources f0, f2, f3; when the information bit is 10, the information can be sent on the frequency resource f2 and not sent on the frequency resources f0, f1, f3; when the information bit is 11, the information can be sent on the frequency resource f3 and not sent on the frequency resources f0, f1, f2. Similarly, the receiving end can compare the power levels on multiple frequency resources to determine what the transmitted information is.

[0214] 7. Wake-up Signal and Paging Message

[0215] The wake-up signal represents the signal received by the terminal device using the wake-up circuit. As an example, the wake-up signal can be used to wake up at least one terminal device. As an example, the wake-up signal can be used to indicate paging-related information, which may include, for example: whether one terminal device or a group of terminal devices is being paged.

[0216] Regarding the specific content of the wake-up signal, the embodiments of the present application are not limited. In the embodiments of the present application, the wake-up signal represents a type of signal, that is, the signal transmitted on the wake-up link, and it is not limited to being the wake-up signal for a certain terminal device.

[0217] The paging message may indicate which terminal devices are paged. As an example, the terminal device receives the paging message using the main circuit. As an example, the paging message may include paging PDSCH (paging PDSCH) and paging PDCCH (paging PDCCH).

[0218] 8. Radio resource management (RRM) measurement: When the terminal device is in an idle or inactive state, the terminal device can perform RRM measurement by receiving a synchronization signal block (SSB). Among them, SSB may include two parts, namely, a synchronization signal (SS) and a physical broadcast channel block (PBCH). Among them, SS may include a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). Therefore, it can also be considered that SSB includes three parts, that is, SSB includes PSS, SSS, and PBCH, and there is no restriction on this.

[0219] As an example, RRM measurement (or also referred to as cell measurement) includes serving cell measurement and neighbor cell measurement. As an example, neighbor cell measurement includes intra-frequency measurement, inter-frequency measurement and inter-radio access technology (inter-RAT) measurement.

[0220] As an example, the measurement indicator (metric) (or measurement quantity) includes at least one of the following: secondary synchronization signal-reference signal received power (SS-RSRP) and secondary synchronization signal-reference signal received quality (SS-RSRQ). It can be understood that any measurement indicator that can be used to characterize cell quality is applicable to the embodiments of the present application.

[0221] SS-RSRP represents: the linear average over the power contributions of the resource elements (RE) that carry secondary synchronization signals. As an example, the unit of SS-RSRP is Watt, which is an absolute value of power.

[0222] Among them, SS-RSRQ satisfies the following formula: SS-RSRQ = N × SS-RSRP / NR carrier RSSI. Among them, N represents the number of resource blocks (resource blocks, RBs) of the NR carrier received signal strength indicator (NR carrier received signal strength indicator, NR carrier RSSI) measurement bandwidth. NR carrier RSSI refers to the linear mean of the total power received under a specific orthogonal frequency division multiplexing (OFDM) symbol (OFDM symbol) and a specific bandwidth (such as N RBs), in watts, where the total power represents the total power of co-channel serving and non-serving cells, adjacent channel interference, thermal noise, etc.

[0223] For example, the terminal device may measure different cells, and determine whether to perform cell reselection based on the measurement results (such as the above-mentioned measurement indicators).

[0224] After the wake-up circuit is introduced, how the terminal device performs cell measurement is a problem worth considering. In view of this, the present application proposes a method to solve the above problem.

[0225] It should be noted that in this application, "indication" may include direct indication, indirect indication, explicit indication, and implicit indication. When describing that a certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0226] In the present application, the information indicated by the indication information is referred to as the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association relationship between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved by means of the arrangement order of each information agreed in advance (for example, specified by the protocol), thereby reducing the indication overhead to a certain extent. In addition, the information to be indicated can be sent as a whole, or it can be divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different.

[0227] In addition, in the present application, the expression " / " is used to indicate that the objects associated with each other are in an "or" relationship; for example, A / B can represent: A or B. The expression "and / or" is used to indicate that the objects associated with each other can be in an and relationship or an or relationship; for example, A and / or B can represent the following situations: A exists alone, B exists alone, and A and B exist at the same time, where A and B can be single or multiple. "At least one of the following" or similar expressions are used to indicate any combination of the listed items; for example, at least one of A, B and / or C can represent the following situations: A exists alone, B exists alone, C exists alone, A and B exist at the same time, B and C exist at the same time, and A and C exist at the same time, where A, B, and C can be single or multiple.

[0228] The method provided by the embodiment of the present application will be described in detail below in conjunction with the accompanying drawings. The embodiment provided by the present application can be applied to the scenarios shown in the above figures without limitation.

[0229] See also Figure 8 , as an example, Figure 8 800 is a schematic diagram of a method 800 for cell measurement provided by an embodiment of the present application. For ease of description, the following exemplary description is given by taking the execution subject of the method 800 as a terminal device as an example. It can be understood that the execution subject of the method 800 can also be a component of the terminal device, such as a chip or a chip system or a circuit, which is not limited to this. The steps described below as being executed by a single execution subject can also be divided into being executed by multiple execution subjects, and these execution subjects can be logically and / or physically separated. Figure 8 The illustrated method 800 may include the following steps.

[0230] 810. The terminal device measures the serving cell.

[0231] Optionally, the terminal device includes a wake-up circuit (or a wake-up module) and a main circuit (or a main module), and the terminal device uses the wake-up circuit to perform serving cell measurement. Further optionally, the terminal device uses the main circuit to perform neighboring cell measurement. For the wake-up circuit and the main circuit, please refer to the description of the previous terminology explanation section, which will not be repeated here.

[0232] Specifically, when the terminal device uses the wake-up circuit to monitor the wake-up signal, if the terminal device uses the main circuit to perform cell measurement, then the terminal device needs to periodically turn on the main circuit to perform cell measurement, such as turning on the main circuit every few hundred milliseconds or every few seconds to perform cell measurement, which will greatly reduce the power consumption benefit of the wake-up circuit to the terminal device. Therefore, the wake-up circuit can be used to perform partial cell measurements, which reduces the operation of turning on the main circuit to perform cell measurement and improves the power consumption benefit of the wake-up circuit to the terminal device. Among them, cell measurement can also be called RRM measurement, including service cell measurement and neighbor cell measurement.

[0233] In a possible implementation manner, the terminal device uses a wake-up circuit to perform serving cell measurement and uses a main circuit to perform neighbor cell measurement.

[0234] In another possible implementation, when the terminal device monitors the wake-up signal, the terminal device uses the wake-up circuit to perform cell measurement; when the terminal device monitors the paging message, the terminal device uses the main circuit to perform cell measurement. As a further example, the terminal device uses the wake-up circuit to perform cell measurement, including: the terminal device uses the wake-up circuit to perform serving cell measurement. As a further example, the terminal device uses the main circuit to perform cell measurement, including: the terminal device uses the main circuit to perform serving cell measurement and / or neighbor cell measurement.

[0235] In the embodiments of the present application, for ease of explanation, the use of a wake-up circuit to perform service cell measurement and the use of a main circuit to perform neighbor cell measurement are used as examples for exemplary explanation. It can be understood that the solution in which the terminal device uses a wake-up circuit to perform partial cell measurement is applicable to the embodiments of the present application.

[0236] Optionally, the terminal device measures the serving cell, including: the terminal device receives a first reference signal, and determines the cell quality of the serving cell based on the first reference signal.

[0237] Specifically, the terminal device determines the value of the measurement amount according to the first reference signal, wherein the measurement amount can be used to characterize the cell quality of the serving cell. As an example, the measurement amount includes at least one of the following: reference signal received power (reference signal received power, RSRP) (or low power (low power, LP)-RSRP), reference signal received quality (reference signal received quality, RSRQ) (or LP-RSRQ), signal to interference and noise ratio (signal to interference and noise ratio, SINR) (or LP-SINR).

[0238] As an example, the first reference signal is a low power synchronization signal (LP-SS). Based on this, the above measurement amount can be obtained according to LP-SS measurement.

[0239] As an example, the modulation mode of the first reference signal is OOK or FSK. The modulation mode of the first reference signal is OOK, which can also be replaced by: in the time interval corresponding to the first reference signal, some time domain positions have energy, and some time domain positions have no energy.

[0240] As an example, the terminal device receives the first reference signal using a wake-up circuit.

[0241] 820. The terminal device starts or stops measuring neighboring cells according to the cell quality of the serving cell and M thresholds, where M is an integer greater than 1.

[0242] The M thresholds are thresholds for the cell quality of the serving cell. Specifically, the terminal device can compare the measured cell quality of the serving cell with the threshold, and then perform corresponding operations according to the comparison result. The threshold can be a numerical value or a numerical range, which is not limited.

[0243] Optionally, the terminal device measures the neighboring cell, including: the terminal device receives a second reference signal, and determines the cell quality of the neighboring cell based on the second reference signal.

[0244] Specifically, the terminal device determines the value of the measurement amount according to the second reference signal, wherein the measurement amount can be used to characterize the cell quality of the neighboring cell. As an example, the measurement amount includes at least one of the following: RSRP (such as SS-RSRP), RSRQ (such as SS-RSRQ), SINR.

[0245] As an example, the second reference signal is SSB. Based on this, the above measurement amount can be obtained based on SSB measurement. For example, the terminal device can measure based on PSS and / or SSS and / or PBCH demodulation reference signal (DMRS) in SSB.

[0246] As an example, the terminal device receives the second reference signal using the primary circuit.

[0247] Taking M=2, that is, the M thresholds include the first threshold and the second threshold as an example, optionally, in step 820, the terminal device starts or stops measuring the neighboring cell according to the cell quality of the serving cell and the M thresholds, including:

[0248] When the terminal device does not measure the neighboring cell, the terminal device starts measuring the neighboring cell according to the cell quality of the serving cell and the first threshold;

[0249] When the terminal device measures a neighboring cell, the terminal device stops measuring the neighboring cell according to the cell quality of the serving cell and the second threshold.

[0250] The first threshold and the second threshold are different. Specifically, the first threshold and the second threshold have different functions, or the first threshold and the second threshold are two different parameters, so the first threshold and the second threshold are different.

[0251] Based on this, if the terminal device does not perform neighboring cell measurement, the terminal device can determine whether to start performing neighboring cell measurement based on the cell quality of the serving cell and the first threshold; if the terminal device performs neighboring cell measurement, the terminal device can determine whether to stop performing neighboring cell measurement based on the cell quality of the serving cell and the second threshold. Take the case where the terminal device uses a wake-up circuit to perform service cell measurement and uses a main circuit to perform neighboring cell measurement as an example. Specifically, if the terminal device currently uses a wake-up circuit to perform service cell measurement and does not use the main circuit to perform neighboring cell measurement, the terminal device can determine whether to use the main circuit to perform neighboring cell measurement based on the cell quality of the serving cell measured using the wake-up circuit and the first threshold; if the terminal device currently uses a wake-up circuit to perform service cell measurement and uses the main circuit to perform neighboring cell measurement, the terminal device can determine whether to stop using the main circuit to perform neighboring cell measurement based on the cell quality of the serving cell measured using the wake-up circuit and the second threshold.

[0252] Optionally, the terminal device starts measuring neighboring cells according to the cell quality of the serving cell and the first threshold, including: the cell quality of the serving cell is less than or equal to the first threshold, and the terminal device starts measuring neighboring cells; and / or, the terminal device stops measuring neighboring cells according to the cell quality of the serving cell and the second threshold, including: the cell quality of the serving cell is greater than or equal to the second threshold, and the terminal device stops measuring neighboring cells. Conversely, if the cell quality of the serving cell is greater than the first threshold, the terminal device does not measure the neighboring cell; and / or, if the cell quality of the serving cell is less than the second threshold, the terminal device does not stop measuring the neighboring cell. Here and in the following description, "less than or equal to the first threshold" can be replaced with "less than the first threshold", and "greater than or equal to the second threshold" can be replaced with "greater than the second threshold". Accordingly, "greater than the first threshold" can be replaced with "greater than or equal to the first threshold", and "less than the second threshold" can be replaced with "less than or equal to the second threshold". The relevant descriptions of "third threshold" to "sixth threshold" are similar to this.

[0253] Taking the case where the terminal device uses the wake-up circuit to perform service cell measurement and uses the main circuit to perform neighbor cell measurement as an example, specifically, when the terminal device uses the wake-up circuit to perform service cell measurement and does not use the main circuit to perform neighbor cell measurement, if the cell quality of the service cell measured by the terminal device using the wake-up circuit is less than or equal to the first threshold, then the terminal device starts to use the main circuit to perform neighbor cell measurement; if the cell quality of the service cell measured by the terminal device using the wake-up circuit is greater than the first threshold, then the terminal device continues to not use the main circuit to perform neighbor cell measurement. When the terminal device uses the wake-up circuit to perform service cell measurement and uses the main circuit to perform neighbor cell measurement, if the cell quality of the service cell measured by the terminal device using the wake-up circuit is greater than or equal to the second threshold, then the terminal device stops using the main circuit to perform neighbor cell measurement; if the cell quality of the service cell measured by the terminal device using the wake-up circuit is less than the second threshold, then the terminal device continues to use the main circuit to measure the neighbor cell.

[0254] Combine the following Fig. 9 to explain.

[0255] See also Fig. 9 , as an example, Fig. 9 It is a schematic diagram of cell measurement applicable to an embodiment of the present application.

[0256] like Fig. 9As shown, the embodiment of the present application takes into account the scenario of terminal device movement, such as the terminal device moving from the cell center to the cell edge, and the terminal device moving from the cell edge to the cell center, so two thresholds can be designed, namely the first threshold and the second threshold. Through these two thresholds, it can be determined how to perform cell measurement, or which circuit (such as a wake-up circuit and / or a main circuit) to use to perform cell measurement, or whether to perform neighboring cell measurement.

[0257] like Fig. 9 As shown in (a), assuming that the terminal device moves from the cell center to the cell edge, when the terminal device has not crossed the boundary corresponding to the first threshold (that is, the cell quality of the serving cell is greater than the first threshold), the terminal device performs the serving cell measurement; when the terminal device crosses the boundary corresponding to the first threshold (that is, the cell quality of the serving cell is less than or equal to the first threshold), considering that the cell quality of the neighboring cell may be better than the cell quality of the serving cell, the terminal device may perform the neighboring cell measurement so that the terminal device can reselect to a cell with better cell quality, that is, when the terminal device crosses the boundary corresponding to the first threshold, the cell measurement performed by the terminal device includes the serving cell measurement and the neighboring cell measurement.

[0258] Taking the example of a terminal device using a wake-up circuit to measure a service cell and using a main circuit to measure a neighboring cell, specifically, when the terminal device has not crossed the boundary corresponding to the first threshold (that is, the cell quality of the service cell is greater than the first threshold), the terminal device can use the wake-up circuit to perform cell measurement (that is, service cell measurement); when the terminal device crosses the boundary corresponding to the first threshold, the terminal device begins to use the main circuit to perform cell measurement (that is, neighboring cell measurement), that is, after the terminal device crosses the boundary corresponding to the first threshold, the cell measurement performed by the terminal device includes cell measurement performed using the wake-up circuit (that is, service cell measurement) and cell measurement performed using the main circuit (that is, neighboring cell measurement).

[0259] like Fig. 9 As shown in (b), assuming that the terminal device moves from the edge of the cell to the center of the cell, when the terminal device has not crossed the boundary corresponding to the second threshold (that is, the cell quality of the serving cell is less than the second threshold), the terminal device performs serving cell measurement and neighboring cell measurement; when the terminal device crosses the boundary corresponding to the second threshold (that is, the cell quality of the serving cell is greater than or equal to the second threshold), the terminal device can stop performing neighboring cell measurement (at this time, the quality of the serving cell is good enough, and the terminal device does not need to consume power to measure the neighboring cell), that is, when the terminal device crosses the boundary corresponding to the second threshold, considering that the cell quality of the serving cell may be better than the cell quality of the neighboring cell, the cell measurement performed by the terminal device is the serving cell measurement.

[0260] Taking the example of a terminal device using a wake-up circuit to measure a service cell and using a main circuit to measure a neighboring cell, specifically, when the terminal device has not crossed the boundary corresponding to the second threshold (that is, the cell quality of the service cell is less than the second threshold), the terminal device uses the wake-up circuit and the main circuit to perform cell measurement (that is, the wake-up circuit is used to perform service cell measurement and the main circuit is used to perform neighboring cell measurement); when the terminal device crosses the boundary corresponding to the second threshold (that is, the cell quality of the service cell is greater than or equal to the second threshold), the terminal device stops using the main circuit to perform cell measurement, that is, when the terminal device crosses the boundary corresponding to the second threshold, the cell measurement performed by the terminal device includes the cell measurement performed using the wake-up circuit (that is, the service cell measurement).

[0261] Optionally, when the cell quality of the serving cell is less than or equal to a first threshold, the measurement of the neighboring cell is started, including: when the cell quality of the serving cell is less than or equal to the first threshold within a first time period, the measurement of the neighboring cell is started after the first time period. In this way, the cell quality over a period of time can be compared with the first threshold. Compared with comparing only the cell quality at a certain moment, this method can reduce the impact of random errors. It can be understood that the embodiments of the present application do not limit the terminal device to measuring the serving cell at all times within the first time period. For example, the terminal device can perform measurements according to the measurement period within the first time period. For example, assuming that the terminal device measures the serving cell once every 1s and the duration of the first time period is 10s, the terminal device can measure 10 times within the first time period.

[0262] As an example, the cell quality of the serving cell is less than or equal to the first threshold value in the first time period, which may be that, in the first time period, the cell quality of the serving cell is less than or equal to the first threshold value. For example, assuming that the terminal device measures the serving cell once every 1s, and the duration of the first time period is 10s, then the cell quality of the serving cell is less than or equal to the first threshold value in the first time period, which can be equivalently described as the measurement results of the serving cell for 10 consecutive times are less than or equal to the first threshold value.

[0263] As another example, the cell quality of the serving cell is less than or equal to the first threshold value during the first time period, which may be that, during the first time period, the number of times that the cell quality of the serving cell is less than or equal to the first threshold value exceeds a first preset number of times. For example, assuming that the terminal device measures the serving cell once every 1s, the duration of the first time period is 10s, and the first preset number of times is 8, then the cell quality of the serving cell is less than or equal to the first threshold value during the first time period, which can be equivalently described as 8 consecutive measurement results of the serving cell are less than or equal to the first threshold value. Among them, the first preset number of times is greater than 1, and the first preset number of times can be predefined, or preconfigured, or pre-agreed, or configured by the network device, which is not limited to this.

[0264] Optionally, the cell quality of the serving cell is greater than or equal to the second threshold, and the measurement of the neighboring cell is stopped, including: the cell quality of the serving cell is greater than or equal to the second threshold within the second time period, and the measurement of the neighboring cell is stopped after the second time period. In this way, the cell quality over a period of time can be compared with the second threshold, and compared with only comparing the cell quality at a certain moment, this method can reduce the impact of random errors.

[0265] As an example, the cell quality of the serving cell is greater than or equal to the second threshold in the second time period, which may be that, in the second time period, the cell quality of the serving cell is greater than or equal to the second threshold.

[0266] As another example, the cell quality of the serving cell is greater than or equal to the second threshold value within the second time period, which may be that, within the second time period, the number of times that the cell quality of the serving cell is greater than or equal to the second threshold value exceeds a second preset number. The second preset number is greater than 1, and the second preset number may be predefined, or preconfigured, or pre-agreed, or configured by a network device, which is not limited.

[0267] It can be understood that the embodiment of the present application does not limit the terminal device to measuring the service cell all the time during the first time period. For details, please refer to the previous description about the first time period.

[0268] The time lengths of the first time period and the second time period may be the same or different, and there is no limitation on this.

[0269] Optionally, the terminal device may determine the first time period and the second time period in any of the following ways.

[0270] In a first possible implementation manner, the network device sends indication information #1 to the terminal device, where the indication information #1 indicates the first time period and / or the second time period.

[0271] The indication information #1 may be in the form of configuration information, such as the indication information #1 is configuration information carried in radio resource control (RRC) signaling. As an example, the configuration information is carried in RRC signaling carried in a system information block (SIB).

[0272] In one example, the indication information #1 indicates the first time period and the second time period. Through this implementation, the terminal device can learn the first time period and the second time period based on the indication information #1.

[0273] In another example, indication information #1 indicates a first time period, and the first time period is associated with a second time period. The terminal device can obtain the first time period based on indication information #1, and determine the second time period associated with the first time period based on the association relationship between the first time period and the second time period.

[0274] In another example, indication information #1 indicates a second time period, and the first time period is associated with the second time period. The terminal device can obtain the second time period based on indication information #1, and determine the first time period associated with the second time period based on the association relationship between the first time period and the second time period.

[0275] In the above two examples, the association relationship between the first time period and the second time period may be predefined, preconfigured, pre-agreed, or indicated by a network device, without limitation.

[0276] In another example, the indication information #1 indicates the second time period, and the first time period is predefined, preconfigured, or pre-agreed.

[0277] In another example, the indication information #1 indicates a first time period, and the second time period is predefined, preconfigured, or pre-agreed.

[0278] In a second possible implementation manner, the first time period and the second time period are predefined, preconfigured, or pre-agreed.

[0279] In a third possible implementation, a time period is associated with a threshold, so that the time period associated with the threshold can be determined by the threshold.

[0280] In one example, the first time period is associated with the first threshold value. After the terminal device determines the first threshold value, it can determine the first time period associated with the first threshold value based on the association relationship between the first threshold value and the first time period. The association relationship between the first time period and the first threshold value can be predefined, preconfigured, pre-agreed, or indicated by the network device, which is not limited. For the manner in which the terminal device determines the first threshold value, please refer to the following description.

[0281] In another example, the second time period is associated with the second threshold value. After the terminal device determines the second threshold value, it can determine the second time period associated with the second threshold value based on the association relationship between the second threshold value and the second time period. The association relationship between the second time period and the second threshold value can be predefined, or preconfigured, or pre-agreed, or indicated by the network device, which is not limited. For the manner in which the terminal device determines the second threshold value, please refer to the following description.

[0282] It can be understood that the above three implementation methods are for illustrative purposes only and are not intended to be limiting. Variations of the above implementation methods are all applicable to the embodiments of the present application.

[0283] The values ​​of the first threshold and the second threshold may be different or partially overlapped, and this is not limited. For example, the first threshold corresponds to a numerical range, and the second threshold corresponds to a numerical range, and the numerical range corresponding to the first threshold and the numerical range corresponding to the second threshold may partially overlap.

[0284] Optionally, the first threshold is less than the second threshold. Fig. 9 For example, when the terminal device moves from the cell center to the cell edge, when the cell quality of the service cell is less than or equal to the first threshold, the terminal device starts to use the main circuit to measure the neighboring cell. Therefore, the first threshold is set relatively low, so that the terminal device can perform service cell measurements in a larger range, that is, use the wake-up circuit to measure the service cell, thereby achieving energy saving effect.

[0285] Optionally, the terminal device may determine the first threshold and the second threshold in any of the following ways.

[0286] In a first possible implementation manner, the network device sends indication information #2 to the terminal device, where the indication information #2 indicates the first threshold and / or the second threshold.

[0287] The indication information #2 may be in the form of configuration information, such as the indication information #2 being configuration information carried in RRC signaling. As an example, the configuration information is carried in RRC signaling carried in SIB. The indication information #2 and the indication information #1 may be carried in the same signaling or in different signalings, which is not limited.

[0288] In one example, the indication information #2 indicates the first threshold and the second threshold. Through this implementation, the terminal device can learn the first threshold and the second threshold based on the indication information #2.

[0289] In another example, indication information #2 indicates a first threshold, and the first threshold is associated with a second threshold. The terminal device can obtain the first threshold based on indication information #2, and determine the second threshold associated with the first threshold based on the association relationship between the first threshold and the second threshold.

[0290] In another example, indication information #2 indicates a second threshold, and the first threshold is associated with the second threshold. The terminal device can obtain the second threshold based on indication information #2, and determine the first threshold associated with the second threshold based on the association relationship between the first threshold and the second threshold.

[0291] In the above two examples, the association relationship between the first threshold and the second threshold may be predefined, preconfigured, pre-agreed, or indicated by a network device, without limitation.

[0292] In another example, the indication information #2 indicates the second threshold, and the first threshold is predefined, preconfigured, or pre-agreed.

[0293] In another example, the indication information #2 indicates the first threshold, and the second threshold is predefined, preconfigured, or pre-agreed.

[0294] In a second possible implementation manner, the first threshold and the second threshold are predefined, preconfigured, or pre-agreed.

[0295] In a third possible implementation, a time period is associated with a threshold value, so that the threshold value associated with the time period can be determined by the time period.

[0296] In one example, the first time period is associated with the first threshold value. After the terminal device determines the first time period, it can determine the first threshold value associated with the first time period based on the association relationship between the first threshold value and the first time period. The association relationship between the first time period and the first threshold value can be predefined, preconfigured, pre-agreed, or indicated by the network device, which is not limited. For the manner in which the terminal device determines the first time period, reference can be made to the previous description.

[0297] In another example, the second time period is associated with the second threshold value. After the terminal device determines the second time period, it can determine the second threshold value associated with the second time period based on the association relationship between the second threshold value and the second time period. The association relationship between the second time period and the second threshold value can be predefined, preconfigured, pre-agreed, or indicated by the network device, which is not limited. For the manner in which the terminal device determines the second time period, please refer to the following description.

[0298] It can be understood that the above three implementation methods are for illustrative purposes only and are not intended to be limiting. Variations of the above implementation methods are all applicable to the embodiments of the present application.

[0299] The above-mentioned method of using M thresholds (such as the first threshold and the second threshold) to determine how to perform cell measurement, or which circuit (such as the wake-up circuit and / or the main circuit) to use to perform cell measurement, or whether to perform measurement of neighboring cells is more accurate than one threshold.

[0300] Specifically, assuming that a threshold is used to determine how to perform cell measurement, for example, when the cell quality of the service cell measured by the terminal device using the wake-up circuit is higher than a threshold, it can be considered that the terminal device is in the center of the cell, and at this time the terminal device is far away from the neighboring cell, and the neighboring cell can be not measured; when the cell quality of the service cell measured by the terminal device using the wake-up circuit is lower than the threshold, it can be considered that the terminal device is at the edge of the cell, and at this time the terminal device is close to the neighboring cell and can measure the neighboring cell. Considering that the wake-up circuit is a low-power receiver, the measurement accuracy may be relatively poor.

[0301] See also Fig.10 , as an example, Fig.10Figure 1 is a schematic diagram of the wake-up circuit measurement under different signal-to-noise ratios. Fig.10 As shown, taking RSRP as an example, in the case of high signal-to-noise ratio, the power of the signal (the signal used for cell measurement) is higher than the interference / noise power, so the interference / noise has little effect on the measurement result (i.e., the measured RSRP); in the case of low signal-to-noise ratio, the power of the signal (the signal used for cell measurement) is equivalent to the interference / noise power, or even smaller than the interference / noise power, so the interference / noise may have a greater impact on the measurement result (i.e., the measured RSRP). If a threshold is used to determine how to perform cell measurement, then if the threshold is set high, the threshold may correspond to a high signal-to-interference-to-noise ratio (SINR) situation, in which case the measurement result is relatively reliable, but this condition can only be met when the terminal device is in the center of the cell, that is, only when the terminal device is in the center of the cell, it is not necessary to perform neighboring cell measurement, which will reduce the overall power consumption benefit. If the threshold is set low, the threshold may correspond to a low signal-to-interference-to-noise ratio situation, then the measurement result may be unreliable, and interference / noise may cause a ping-pong effect (i.e., due to random fluctuations in interference / noise, the RSRP measured by the terminal device is sometimes higher than the threshold and sometimes lower than the threshold).

[0302] Therefore, the above problems can be avoided by designing at least two thresholds (such as a first threshold and a second threshold). Specifically, when the terminal device moves from the cell center to the cell edge, the terminal device can compare the cell quality of the service cell with the first threshold. For example, when the cell quality of the service cell is less than or equal to the first threshold, the terminal device starts to use the main circuit to measure the neighboring cell. In this way, the terminal device can perform service cell measurements in a larger range, that is, use the wake-up circuit to measure the service cell, thereby achieving energy saving. When the terminal device moves from the cell edge to the cell center, the terminal device can compare the cell quality of the service cell with the second threshold. For example, when the cell quality of the service cell is greater than or equal to the second threshold, the terminal device stops measuring the neighboring cell. This can reduce the impact of interference / noise on the measurement results and avoid the ping-pong effect.

[0303] See also Fig.11 , as an example, Fig.11 1 is a schematic diagram of a method 1100 for cell measurement provided by another embodiment of the present application. For ease of description, the following exemplary description is given by taking the execution subject of method 1100 as a terminal device as an example. It can be understood that the execution subject of method 1100 can also be a component of the terminal device, such as a chip or a chip system or a circuit, which is not limited to this. The steps described below as being executed by a single execution subject can also be divided into being executed by multiple execution subjects, and these execution subjects can be logically and / or physically separated. Fig.11 The illustrated method 1100 may include the following steps.

[0304] 1110. The terminal device measures the service cell.

[0305] Optionally, the terminal device includes a wake-up circuit (or a wake-up module) and a main circuit (or a main module), and the terminal device can use the wake-up circuit to perform serving cell measurement, or can also use the main circuit to perform serving cell measurement. Further optionally, the terminal device uses the main circuit to perform neighboring cell measurement.

[0306] 1120. The terminal device monitors the paging message or the wake-up signal according to the cell quality of the serving cell and N thresholds, where N is an integer greater than 1.

[0307] The N thresholds are thresholds for the cell quality of the serving cell. Specifically, the terminal device can compare the measured cell quality of the serving cell with the threshold, and then perform corresponding operations according to the comparison result. The threshold can be a numerical value or a numerical range, which is not limited.

[0308] Here, the word “monitor” may also be replaced by “receive”, “detect” or “read”.

[0309] For the wake-up signal and paging message, please refer to the explanation in the previous terminology section, which will not be repeated here.

[0310] Taking N=2, that is, N thresholds include the third threshold and the fourth threshold as an example, optionally, in step 820, the terminal device monitors the paging message or the wake-up signal according to the cell quality of the serving cell and the N thresholds, including:

[0311] In the case of monitoring the wake-up signal, the terminal device monitors the paging message according to the cell quality of the serving cell and the third threshold;

[0312] In the case of monitoring the paging message, the terminal device monitors the wake-up signal according to the cell quality of the serving cell and the fourth threshold.

[0313] The third threshold value is different from the fourth threshold value. Specifically, the third threshold value and the fourth threshold value have different functions, or the third threshold value and the fourth threshold value are two different parameters, so the third threshold value and the fourth threshold value are different.

[0314] Based on this, when the terminal device monitors the wake-up signal, the terminal device can determine whether to monitor the paging message based on the cell quality of the service cell and the third threshold; when the terminal device monitors the paging message, the terminal device can determine whether to monitor the wake-up signal based on the cell quality of the service cell and the fourth threshold.

[0315] Optionally, the terminal device includes a wake-up circuit (or wake-up module) and a main circuit (or main module), the terminal device uses the wake-up circuit to monitor the wake-up signal, and the terminal device uses the main circuit to monitor the paging message.

[0316] Optionally, the terminal device includes a wake-up circuit (or wake-up module) and a main circuit (or main module). The terminal device monitors the paging message, and it can also be replaced by the terminal device using the main circuit to perform service cell measurement; the terminal device monitors the wake-up signal, and it can also be replaced by the terminal device using the wake-up circuit to perform service cell measurement.

[0317] Based on this, when the terminal device monitors the wake-up signal (that is, when the terminal device uses the wake-up circuit to perform service cell measurement), the terminal device can determine whether to monitor the paging message (that is, whether to use the main circuit to perform service cell measurement) based on the cell quality of the service cell measured using the wake-up circuit and the third threshold; when the terminal device monitors the paging message (that is, when the terminal device uses the main circuit to perform service cell measurement), the terminal device can determine whether to monitor the wake-up signal (that is, whether to use the wake-up circuit to perform service cell measurement) based on the cell quality of the service cell measured using the main circuit and the fourth threshold.

[0318] Optionally, the terminal device monitors the paging message according to the cell quality of the serving cell and the third threshold, including: if the cell quality of the serving cell is less than or equal to the third threshold, the terminal device monitors the paging message; and / or, the terminal device monitors the wake-up signal according to the cell quality of the serving cell and the fourth threshold, including: if the cell quality of the serving cell is greater than or equal to the fourth threshold, the terminal device monitors the wake-up signal. Conversely, if the cell quality of the serving cell is greater than the third threshold, the terminal device does not monitor the paging message; and / or, if the cell quality of the serving cell is less than the fourth threshold, the terminal device does not monitor the wake-up signal.

[0319] Specifically, in the case where the terminal device monitors the wake-up signal (that is, the terminal device uses the wake-up circuit to perform service cell measurement), if the cell quality of the service cell measured by the terminal device using the wake-up circuit is less than or equal to the third threshold, then the terminal device starts to monitor the paging message (that is, starts to use the main circuit to perform service cell measurement); if the cell quality of the service cell measured by the terminal device using the wake-up circuit is greater than the third threshold, then the terminal device keeps (or maintains) monitoring the wake-up signal (that is, keeps using the wake-up circuit to perform service cell measurement) and does not monitor the paging message (that is, does not use the main circuit to perform service cell measurement). In the case where the terminal device monitors the paging message (that is, the terminal device uses the main circuit to perform service cell measurement), if the cell quality of the service cell measured by the terminal device using the main circuit is greater than or equal to the fourth threshold, then the terminal device starts to monitor the wake-up signal (that is, starts to use the wake-up circuit to perform service cell measurement); if the cell quality of the service cell measured by the terminal device using the main circuit is less than the fourth threshold, then the terminal device keeps (or maintains) monitoring the paging message (that is, keeps using the main circuit to perform service cell measurement) and does not monitor the wake-up signal (that is, does not use the wake-up circuit to perform service cell measurement).

[0320] Combine the following Fig.12 to explain.

[0321] See also Fig.12 , as an example, Fig.12 It is a schematic diagram of cell measurement applicable to another embodiment of the present application.

[0322] like Fig.12 As shown, the embodiment of the present application takes into account the scenario of terminal device movement, such as the terminal device moving from the cell center to the cell edge, and the terminal device moving from the cell edge to the cell center, so two thresholds can be designed, namely the third threshold and the fourth threshold. Through these two thresholds, it can be determined whether to monitor the paging message or the wake-up signal, or which circuit (such as the wake-up circuit and / or the main circuit) is used to perform the serving cell measurement.

[0323] like Fig.12 As shown in (a), assuming that the terminal device moves from the center of the cell to the edge of the cell, when the terminal device has not crossed the boundary corresponding to the third threshold (that is, the cell quality of the serving cell is greater than the third threshold), the terminal device monitors the wake-up signal (that is, uses the wake-up circuit to perform service cell measurement); when the terminal device crosses the boundary corresponding to the third threshold (that is, the cell quality of the serving cell is less than or equal to the third threshold), the terminal device starts to monitor the paging message (that is, the terminal device starts to use the main circuit to perform service cell measurement).

[0324] like Fig.12As shown in (b), assuming that the terminal device moves from the edge of the cell to the center of the cell, when the terminal device has not crossed the boundary corresponding to the fourth threshold (that is, the cell quality of the serving cell is less than the fourth threshold), the terminal device monitors the paging message (that is, the terminal device uses the main circuit to perform the serving cell measurement); when the terminal device crosses the boundary corresponding to the fourth threshold (that is, the cell quality of the serving cell is greater than or equal to the fourth threshold), the terminal device starts to monitor the wake-up signal (that is, starts to use the wake-up circuit to perform the serving cell measurement).

[0325] Optionally, after the terminal device determines to monitor the paging message based on the cell quality of the serving cell and the third threshold, the terminal device no longer monitors the wake-up signal.

[0326] For example, when the terminal device monitors the wake-up signal (that is, when the terminal device uses the wake-up circuit to perform service cell measurements), if the cell quality of the service cell measured by the terminal device using the wake-up circuit is less than or equal to a third threshold, then the terminal device starts to monitor the paging message (that is, starts to use the main circuit to perform service cell measurements), and the terminal device no longer monitors the wake-up signal (that is, no longer uses the wake-up circuit to perform service cell measurements).

[0327] Optionally, after the terminal device determines to monitor the wake-up signal based on the cell quality of the serving cell and the fourth threshold, the terminal device no longer monitors the paging message.

[0328] For example, when the terminal device monitors paging messages (that is, when the terminal device uses the main circuit to perform service cell measurements), if the cell quality of the service cell measured by the terminal device using the main circuit is greater than or equal to a fourth threshold, the terminal device starts to monitor the wake-up signal (that is, starts to use the wake-up circuit to perform service cell measurements), and the terminal device no longer monitors paging messages (that is, no longer uses the main circuit to perform service cell measurements).

[0329] Optionally, the cell quality of the service cell is less than or equal to the third threshold, and the paging message is monitored, including: when the cell quality of the service cell is less than or equal to the third threshold within the third time period, after the third time period, the terminal device starts to monitor the paging message; in other words, the cell quality of the service cell measured by the terminal device using the wake-up circuit is less than or equal to the third threshold within the third time period, and after the third time period, the terminal device starts to use the main circuit to measure the service cell. In this way, the cell quality over a period of time can be compared with the third threshold, which can reduce the impact of random errors compared to comparing only the cell quality at a certain moment. It can be understood that the embodiment of the present application does not limit the terminal device to measuring the service cell at all times within the third time period. For example, the terminal device can measure according to the measurement cycle within the third time period. For example, assuming that the terminal device measures the service cell once every 1s, and the duration of the third time period is 10s, the terminal device can measure 10 times within the third time period.

[0330] As an example, the cell quality of the serving cell is less than or equal to the third threshold value in the third time period, which may be that, in the third time period, the cell quality of the serving cell is less than or equal to the third threshold value. For example, assuming that the terminal device measures the serving cell once every 1s, and the duration of the third time period is 10s, then the cell quality of the serving cell is less than or equal to the third threshold value in the third time period, which can be equivalently described as the measurement results of the serving cell for 10 consecutive times are less than or equal to the third threshold value.

[0331] As another example, the cell quality of the serving cell is less than or equal to the third threshold value within the third time period, which may be that, within the third time period, the number of times that the cell quality of the serving cell is less than or equal to the third threshold value exceeds the third preset number. For example, assuming that the terminal device measures the serving cell once every 1s, the duration of the third time period is 10s, and the third preset number is 7, then the cell quality of the serving cell is less than or equal to the third threshold value within the third time period, which can be equivalently described as the measurement results of the serving cell for 7 consecutive times are all less than or equal to the third threshold value. Among them, the third preset number is greater than 1, and the third preset number can be predefined, or preconfigured, or pre-agreed, or configured by the network device, which is not limited.

[0332] Optionally, the cell quality of the serving cell is greater than or equal to the fourth threshold, and the wake-up signal is monitored, including: the cell quality of the serving cell is greater than or equal to the fourth threshold in a fourth time period, and the wake-up signal is started to be monitored after the fourth time period; in other words, the cell quality of the serving cell measured by the terminal device using the main circuit is greater than or equal to the fourth threshold in the fourth time period, and after the fourth time period, the terminal device starts to use the wake-up circuit to measure the serving cell. In this way, the cell quality over a period of time can be compared with the fourth threshold, which can reduce the impact of random errors compared to comparing only the cell quality at a certain moment.

[0333] As an example, the cell quality of the serving cell is greater than or equal to the fourth threshold in the fourth time period, which may mean that, in the fourth time period, the cell quality of the serving cell is greater than or equal to the fourth threshold.

[0334] As another example, the cell quality of the serving cell is greater than or equal to the fourth threshold value in the fourth time period, which may be that, in the fourth time period, the number of times that the cell quality of the serving cell is greater than or equal to the third threshold value exceeds a fourth preset number. The fourth preset number is greater than 1, and the fourth preset number may be predefined, or preconfigured, or pre-agreed, or configured by a network device, which is not limited.

[0335] It can be understood that the embodiment of the present application does not limit the terminal device to measuring the service cell all the time during the fourth time period. For details, please refer to the previous description about the third time period.

[0336] The time lengths of the third time period and the fourth time period may be the same or different, and there is no limitation on this.

[0337] Optionally, the terminal device may determine the third time period and the fourth time period in any of the following ways.

[0338] In a first possible implementation manner, the network device sends indication information #3 to the terminal device, where the indication information #3 indicates the third time period and / or the fourth time period.

[0339] The indication information #3 may be in the form of configuration information, such as the indication information #3 is configuration information carried in RRC signaling. As an example, the configuration information is carried in the RRC signaling carried in the SIB.

[0340] In one example, the indication information #3 indicates the third time period and the fourth time period. Through this implementation, the terminal device can learn the third time period and the fourth time period based on the indication information #3.

[0341] In another example, indication information #3 indicates a third time period, and the third time period is associated with a fourth time period. The terminal device can obtain the third time period based on indication information #3, and determine the fourth time period associated with the third time period based on the association relationship between the third time period and the fourth time period.

[0342] In another example, indication information #3 indicates a fourth time period, and the third time period is associated with the fourth time period. The terminal device can learn the fourth time period based on indication information #3, and determine the third time period associated with the fourth time period based on the association relationship between the third time period and the fourth time period.

[0343] In the above two examples, the association relationship between the third time period and the fourth time period may be predefined, preconfigured, pre-agreed, or indicated by a network device, without limitation.

[0344] In another example, indication information #3 indicates a fourth time period, and the third time period is predefined, preconfigured, or pre-agreed.

[0345] In another example, the indication information #3 indicates the third time period, and the fourth time period is predefined, preconfigured, or pre-agreed.

[0346] In a second possible implementation manner, the third time period and the fourth time period are predefined, preconfigured, or pre-agreed.

[0347] In a third possible implementation, a time period is associated with a threshold, so that the time period associated with the threshold can be determined by the threshold.

[0348] In one example, the third time period is associated with the third threshold value. After the terminal device determines the third threshold value, it can determine the third time period associated with the third threshold value based on the association relationship between the third threshold value and the third time period. The association relationship between the third time period and the third threshold value can be predefined, or preconfigured, or pre-agreed, or indicated by the network device, which is not limited. For the manner in which the terminal device determines the third threshold value, please refer to the following description.

[0349] In another example, the fourth time period is associated with the fourth threshold value. After the terminal device determines the fourth threshold value, it can determine the fourth time period associated with the fourth threshold value based on the association relationship between the fourth threshold value and the fourth time period. The association relationship between the fourth time period and the fourth threshold value can be predefined, or preconfigured, or pre-agreed, or indicated by the network device, which is not limited. For the manner in which the terminal device determines the fourth threshold value, please refer to the following description.

[0350] It can be understood that the above three implementation methods are for illustrative purposes only and are not intended to be limiting. Variations of the above implementation methods are all applicable to the embodiments of the present application.

[0351] The values ​​of the third threshold and the fourth threshold may be different or partially overlapped, and this is not limited. For example, the third threshold corresponds to a numerical range, the fourth threshold corresponds to a numerical range, and the numerical range corresponding to the third threshold may partially overlap with the numerical range corresponding to the fourth threshold.

[0352] Optionally, the third threshold is less than the fourth threshold. Fig.12 For example, when the terminal device moves from the cell center to the cell edge, the terminal device starts to monitor the paging message when the cell quality of the service cell is less than or equal to the third threshold. Therefore, the third threshold is set relatively low, so that the terminal device can monitor the wake-up signal in a larger range, that is, use the wake-up circuit to measure the service cell, thereby achieving energy saving effect.

[0353] Optionally, the terminal device may determine the third threshold and the fourth threshold in any of the following ways.

[0354] In a first possible implementation manner, the network device sends indication information #4 to the terminal device, where the indication information #4 indicates the third threshold and / or the fourth threshold.

[0355] The indication information #4 may be in the form of configuration information, such as the indication information #4 being configuration information carried in RRC signaling. As an example, the configuration information is carried in RRC signaling carried in SIB. The indication information #4 and the indication information #3 may be carried in the same signaling or in different signalings, which is not limited.

[0356] In one example, indication information #4 indicates the third threshold and the fourth threshold. Through this implementation, the terminal device can learn the third threshold and the fourth threshold based on indication information #4.

[0357] In another example, indication information #4 indicates a third threshold, and the third threshold is associated with a fourth threshold. The terminal device can obtain the third threshold based on indication information #4, and determine the fourth threshold associated with the third threshold based on the association relationship between the third threshold and the fourth threshold.

[0358] In another example, indication information #4 indicates a fourth threshold, and the third threshold is associated with the fourth threshold. The terminal device can obtain the fourth threshold based on indication information #4, and determine the third threshold associated with the fourth threshold based on the association relationship between the third threshold and the fourth threshold.

[0359] In the above two examples, the association relationship between the third threshold and the fourth threshold may be predefined, preconfigured, pre-agreed, or indicated by a network device, without limitation.

[0360] In another example, indication information #4 indicates the fourth threshold, and the third threshold is predefined, preconfigured, or pre-agreed.

[0361] In another example, indication information #4 indicates the third threshold, and the fourth threshold is predefined, preconfigured, or pre-agreed.

[0362] In a second possible implementation manner, the third threshold and the fourth threshold are predefined, preconfigured, or pre-agreed.

[0363] In a third possible implementation, a time period is associated with a threshold, so that the threshold associated with the time period can be determined by the time period.

[0364] In one example, the third time period is associated with the third threshold value. After the terminal device determines the third time period, it can determine the third threshold value associated with the third time period based on the association relationship between the third threshold value and the third time period. The association relationship between the third time period and the third threshold value can be predefined, or preconfigured, or pre-agreed, or indicated by the network device, which is not limited. For the manner in which the terminal device determines the third time period, reference can be made to the previous description.

[0365] In another example, the fourth time period is associated with the fourth threshold value. After the terminal device determines the fourth time period, it can determine the fourth threshold value associated with the fourth time period based on the association relationship between the fourth threshold value and the fourth time period. The association relationship between the fourth time period and the fourth threshold value can be predefined, or preconfigured, or pre-agreed, or indicated by the network device, which is not limited. For the manner in which the terminal device determines the fourth time period, please refer to the following description.

[0366] It can be understood that the above three implementation methods are for illustrative purposes only and are not intended to be limiting. Variations of the above implementation methods are all applicable to the embodiments of the present application.

[0367] Optionally, in an embodiment of the present application, when the terminal device determines whether to monitor the paging message based on the cell quality of the serving cell and a third threshold, the quality of the serving cell is determined based on a third reference signal. Specifically, the terminal device receives the third reference signal, and determines whether to monitor the paging message based on the cell quality of the serving cell determined by the third reference signal and a third threshold. Specifically, the terminal device determines the value of the measurement quantity based on the third reference signal, wherein the measurement quantity can be used to characterize the cell quality of the serving cell. As an example, the measurement quantity includes at least one of the following: RSRP (or LP-RSRP), RSRQ (or LP-RSRQ), SINR (or LP-SINR).

[0368] As an example, the third reference signal is LP-SS. Based on this, the above measurement amount can be obtained according to LP-SS measurement.

[0369] As an example, the modulation mode of the third reference signal is OOK or FSK. The modulation mode of the third reference signal is OOK, which can also be replaced by: in the time interval corresponding to the third reference signal, some time domain positions have energy, and some time domain positions have no energy.

[0370] As an example, the terminal device receives the third reference signal using a wake-up circuit.

[0371] Optionally, in an embodiment of the present application, when the terminal device determines whether to monitor the wake-up signal based on the cell quality of the serving cell and the fourth threshold, the quality of the serving cell is determined based on the fourth reference signal. Specifically, the terminal device receives the fourth reference signal, and determines whether to monitor the wake-up signal based on the cell quality of the serving cell determined by the fourth reference signal and the fourth threshold. Specifically, the terminal device determines the value of the measurement amount based on the fourth reference signal, wherein the measurement amount can be used to characterize the cell quality of the serving cell. As an example, the measurement amount includes at least one of the following: RSRP (such as SS-RSRP), RSRQ (such as SS-RSRQ), SINR.

[0372] As an example, the fourth reference signal is SSB. Based on this, the above measurement amount can be obtained according to the SSB measurement. For example, the terminal device can measure according to the PSS and / or SSS and / or PBCH DMRS in the SSB.

[0373] As an example, the terminal device receives the fourth reference signal using the primary circuit.

[0374] The above-mentioned monitoring of paging messages or wake-up signals through N thresholds (such as the third threshold and the fourth threshold), or using which circuit (such as the wake-up circuit and / or the main circuit) to perform service cell measurement, is more accurate than one threshold. Specifically, assuming that a threshold is used to judge and monitor paging messages or wake-up signals, then if the threshold is set higher, the threshold may correspond to a high signal-to-interference-to-noise ratio situation, and the measurement result is relatively reliable at this time, but this condition can only be met when the terminal device is in the center of the cell, that is, only when the terminal device is in the center of the cell, it is not necessary to monitor the paging message, which will reduce the overall power consumption benefit. If the threshold is set lower, the threshold may correspond to a low signal-to-interference-to-noise ratio situation, then the measurement result may be unreliable, and interference / noise may cause a ping-pong effect (that is, due to random fluctuations in interference / noise, the RSRP measured by the terminal device is sometimes higher than the threshold and sometimes lower than the threshold), and specific reference may be made to the relevant description in the previous method 800.

[0375] Therefore, the above problems can be avoided by designing at least two thresholds (such as the third threshold and the fourth threshold). Specifically, when the terminal device moves from the cell center to the cell edge, the terminal device can compare the cell quality of the service cell with the third threshold. For example, when the cell quality of the service cell is less than or equal to the third threshold, the terminal device starts to monitor the paging message. In this way, the terminal device can monitor the wake-up signal in a larger range, that is, use the wake-up circuit to measure the service cell, thereby achieving energy saving. When the terminal device moves from the cell edge to the cell center, the terminal device can compare the cell quality of the service cell with the fourth threshold. For example, when the cell quality of the service cell is greater than or equal to the fourth threshold, the terminal device monitors the wake-up signal (that is, uses the wake-up circuit to measure the service cell). This can reduce the impact of interference / noise on the measurement results and avoid the ping-pong effect.

[0376] In the above, the related schemes about M thresholds and N thresholds are introduced respectively in combination with methods 800 and 1100. It can be understood that methods 800 and 1100 can be used alone or in combination, and there is no limitation on this. The following briefly introduces the combined use. For those not described in detail, please refer to the above methods 800 and 1100.

[0377] See also Fig.13 , as an example, Fig.13 It is a schematic diagram of cell measurement applicable to another embodiment of the present application.

[0378] Assume that the M thresholds include a first threshold and a second threshold, and the N thresholds include a third threshold and a fourth threshold. As an example, a threshold among the M thresholds is greater than a threshold among the N thresholds.

[0379] like Fig.13 As shown in (a), assuming that the terminal device moves from the center of the cell to the edge of the cell, when the terminal device does not cross the boundary corresponding to the first threshold (that is, the cell quality of the serving cell is greater than the first threshold), the terminal device can perform service cell measurement (that is, use the wake-up circuit to perform service cell measurement). When the terminal device crosses the boundary corresponding to the first threshold (that is, the cell quality of the serving cell is less than or equal to the first threshold), considering that the cell quality of the neighboring cell may be better than the cell quality of the serving cell, the terminal device can perform neighboring cell measurement (that is, use the main circuit to perform neighboring cell measurement), that is, when the terminal device crosses the boundary corresponding to the first threshold, the cell measurement performed by the terminal device includes service cell measurement performed using the wake-up circuit and neighboring cell measurement performed using the main circuit. Further, when the cell quality of the serving cell crosses the boundary corresponding to the third threshold (that is, the cell quality of the serving cell measured by the terminal device using the wake-up circuit is less than or equal to the third threshold), the terminal device starts to monitor the paging message (that is, the terminal device starts to use the main circuit to perform service cell measurement).

[0380] like Fig.13 As shown in (b), assuming that the terminal device moves from the edge of the cell to the center of the cell, the terminal device has not crossed the boundary corresponding to the fourth threshold (that is, the cell quality of the serving cell is less than the fourth threshold), and the terminal device monitors the paging message (that is, the terminal device uses the main circuit to perform service cell measurement). When the terminal device crosses the boundary corresponding to the fourth threshold (that is, the cell quality of the serving cell is greater than or equal to the fourth threshold), the terminal device starts to monitor the wake-up signal (that is, starts to use the wake-up circuit to perform service cell measurement), and the terminal device can also use the main circuit to perform neighboring cell measurement. Furthermore, when the cell quality of the serving cell crosses the boundary corresponding to the second threshold (that is, the cell quality of the serving cell measured by the terminal device using the wake-up circuit is greater than or equal to the second threshold), the terminal device stops performing neighboring cell measurements.

[0381] See also Fig.14 , as an example, Fig.14 1 is a schematic diagram of a method 1400 for cell measurement provided by another embodiment of the present application. For ease of description, the following exemplary description is given by taking the execution subject of method 1400 as a terminal device as an example. It can be understood that the execution subject of method 1400 can also be a component of the terminal device, such as a chip or a chip system or a circuit, which is not limited to this. The steps described below as being executed by a single execution subject can also be divided into being executed by multiple execution subjects, and these execution subjects can be logically and / or physically separated. Fig.14 The illustrated method 1400 may include the following steps.

[0382] 1410. When the terminal device performs the first measurement on the serving cell, the terminal device performs the second measurement on the serving cell according to the cell quality of the serving cell and a fifth threshold.

[0383] 1420. When the terminal device performs a second measurement on the serving cell, the wake-up signal is monitored according to the cell quality of the serving cell and a sixth threshold.

[0384] The fifth threshold and the sixth threshold are thresholds for the cell quality of the serving cell. Specifically, the terminal device can compare the measured cell quality of the serving cell with the threshold, and then perform corresponding operations according to the comparison result. The fifth threshold and the sixth threshold can be a numerical value or a numerical range, which is not limited.

[0385] The fifth threshold value is different from the sixth threshold value. Specifically, the fifth threshold value and the sixth threshold value have different functions, or the fifth threshold value and the sixth threshold value are two different parameters, so the fifth threshold value and the sixth threshold value are different.

[0386] Based on this, when the terminal device performs the first measurement of the service cell, the terminal device can determine whether to perform the second measurement of the service cell based on the cell quality of the service cell and the fifth threshold; when the terminal device performs the second measurement of the service cell, the terminal device can determine whether to monitor the wake-up signal based on the cell quality of the service cell and the sixth threshold.

[0387] Optionally, the terminal device includes a wake-up circuit (or a wake-up module) and a main circuit (or a main module), and the terminal device performs a first measurement on the service cell, including: the terminal device uses the main circuit to measure the service cell; the terminal device performs a second measurement on the service cell, including: the terminal device uses the wake-up circuit to measure the service cell. Based on this, when the terminal device uses the main circuit to perform service cell measurement, the terminal device can determine whether to use the wake-up circuit to perform service cell measurement based on the cell quality of the service cell and the fifth threshold; when the terminal device uses the wake-up circuit to perform service cell measurement, the terminal device can determine whether to use the wake-up circuit to monitor the wake-up signal based on the cell quality of the service cell and the sixth threshold.

[0388] For the wake-up circuit, main circuit, and wake-up signal, please refer to the explanation in the previous terminology section and will not be repeated here.

[0389] Optionally, the terminal device performs a second measurement on the serving cell according to the cell quality of the serving cell and the fifth threshold, including: if the cell quality of the serving cell is greater than or equal to the fifth threshold, the terminal device performs a second measurement on the serving cell. Conversely, if the cell quality of the serving cell is less than the fifth threshold, the terminal device does not perform a second measurement on the serving cell. For example, the terminal device uses the main circuit to measure the serving cell. If the cell quality of the serving cell is greater than or equal to the fifth threshold, the terminal device starts to use the wake-up circuit to perform the serving cell measurement; if the cell quality of the serving cell is less than the fifth threshold, the terminal device does not use the wake-up circuit to perform the serving cell measurement. Further optionally, if the cell quality of the serving cell is greater than or equal to the fifth threshold, the terminal device performs the second measurement and the first measurement on the serving cell, or the terminal device only performs the second measurement on the serving cell.

[0390] Further optionally, the cell quality of the service cell is greater than or equal to the fifth threshold, and the terminal device performs a second measurement on the service cell, including: when the cell quality of the service cell is greater than or equal to the fifth threshold in the fifth time period, after the fifth time period, the terminal device starts to perform a second measurement on the service cell; in other words, the cell quality of the service cell measured by the terminal device using the main circuit is greater than or equal to the fifth threshold in the fifth time period, and after the fifth time period, the terminal device starts to use the wake-up circuit to measure the service cell. In this way, the cell quality of a period of time can be compared with the fifth threshold, which can reduce the impact of random errors compared to comparing only the cell quality at a certain moment. It can be understood that the embodiment of the present application does not limit the terminal device to measuring the service cell at all times in the fifth time period. For example, the terminal device can measure according to the measurement cycle in the fifth time period. For example, assuming that the terminal device measures the service cell once every 1s, and the duration of the fifth time period is 10s, the terminal device can measure 10 times in the fifth time period.

[0391] As an example, the cell quality of the serving cell is greater than or equal to the fifth threshold value in the fifth time period, which may be that, in the fifth time period, the cell quality of the serving cell is greater than or equal to the fifth threshold value. For example, assuming that the terminal device measures the serving cell once every 1s, and the duration of the fifth time period is 10s, then the cell quality of the serving cell is less than or equal to the fifth threshold value in the fifth time period, which can be equivalently described as the measurement results of the serving cell for 10 consecutive times are less than or equal to the fifth threshold value.

[0392] As another example, the cell quality of the serving cell is greater than or equal to the fifth threshold value within the fifth time period, or the cell quality of the serving cell is less than or equal to the fifth threshold value more than the fifth preset number of times within the fifth time period. For example, assuming that the terminal device measures the serving cell once every 1s, the duration of the fifth time period is 10s, and the fifth preset number of times is 8, then the cell quality of the serving cell is less than or equal to the fifth threshold value within the fifth time period, which can be equivalently described as the measurement results of the serving cell for 8 consecutive times are less than or equal to the fifth threshold value. Among them, the fifth preset number of times is greater than 1, and the fifth preset number of times can be predefined, or preconfigured, or pre-agreed, or configured by the network device, which is not limited.

[0393] Optionally, the terminal device monitors the wake-up signal according to the cell quality of the service cell and the sixth threshold, including: when the cell quality of the service cell is greater than or equal to the sixth threshold, the terminal device monitors the wake-up signal. Conversely, when the cell quality of the service cell is less than the sixth threshold, the terminal device does not monitor the wake-up signal. For example, the terminal device uses the wake-up circuit to measure the service cell. If the cell quality of the service cell is greater than or equal to the sixth threshold, the terminal device starts to monitor the wake-up signal; if the cell quality of the service cell is less than the sixth threshold, the terminal device does not monitor the wake-up signal. Further optionally, when the cell quality of the service cell is greater than or equal to the sixth threshold, the terminal device performs a second measurement on the service cell, that is, only the wake-up circuit is used to perform the service cell measurement, and the main circuit is not used to perform the service cell measurement.

[0394] Further optionally, the cell quality of the serving cell is greater than or equal to the sixth threshold, and the terminal device monitors the wake-up signal, including: when the cell quality of the serving cell is greater than or equal to the sixth threshold within the sixth time period, after the sixth time period, the terminal device starts to monitor the wake-up signal; in other words, the cell quality of the serving cell measured by the terminal device using the wake-up circuit is greater than or equal to the sixth threshold within the sixth time period, and after the sixth time period, the terminal device starts to monitor the wake-up signal. In this way, the cell quality over a period of time can be compared with the sixth threshold, which can reduce the impact of random errors compared to comparing only the cell quality at a certain moment.

[0395] As an example, the cell quality of the serving cell is greater than or equal to the sixth threshold in the sixth time period, which may mean that, in the sixth time period, the cell quality of the serving cell is greater than or equal to the sixth threshold.

[0396] As another example, the cell quality of the serving cell is greater than or equal to the sixth threshold value in the sixth time period, which may be that, in the sixth time period, the number of times that the cell quality of the serving cell is less than or equal to the sixth threshold value exceeds the sixth preset number. The sixth preset number is greater than 1, and the sixth preset number may be predefined, or preconfigured, or pre-agreed, or configured by a network device, which is not limited.

[0397] It can be understood that the embodiment of the present application does not limit the terminal device to measuring the service cell all the time during the sixth time period. For details, please refer to the previous description of the fifth time period.

[0398] The time lengths of the fifth time period and the sixth time period may be the same or different, and there is no limitation on this.

[0399] Optionally, the terminal device may determine the fifth time period and the sixth time period in any of the following ways.

[0400] In a first possible implementation manner, the network device sends indication information #5 to the terminal device, where the indication information #5 indicates the fifth time period and / or the sixth time period.

[0401] In a second possible implementation manner, the fifth time period and the sixth time period are predefined, preconfigured, or pre-agreed.

[0402] In a third possible implementation, a time period is associated with a threshold, so that the time period associated with the threshold can be determined by the threshold.

[0403] The above three methods can refer to the description of the first time period and the second time period in method 800, which will not be repeated here.

[0404] The values ​​of the fifth threshold and the sixth threshold may be different.

[0405] Optionally, the terminal device may determine the fifth threshold and the sixth threshold in any of the following ways.

[0406] In a first possible implementation manner, the network device sends indication information #4 to the terminal device, where the indication information #4 indicates the fifth threshold and / or the sixth threshold.

[0407] In a second possible implementation manner, the fifth threshold and the sixth threshold are predefined, preconfigured, or pre-agreed.

[0408] In a third possible implementation, a time period is associated with a threshold, so that the threshold associated with the time period can be determined by the time period.

[0409] The above three methods can refer to the description of the first threshold and the second threshold in method 800, which will not be repeated here.

[0411] like Fig.15 As shown, the embodiment of the present application considers the scenario where the terminal device moves from the cell edge to the cell center. Fig.15As shown, when the terminal device does not cross the boundary corresponding to the fifth threshold (that is, the cell quality of the serving cell is less than the fifth threshold), the terminal device uses the main circuit to monitor the paging message, and uses the main circuit to perform the serving cell measurement (that is, the terminal device performs the first measurement on the serving cell). When the terminal device crosses the boundary corresponding to the fifth threshold (that is, the cell quality of the serving cell is greater than or equal to the fifth threshold), the terminal device starts to use the wake-up circuit to perform the serving cell measurement, that is, during this period of time, the terminal device uses both the main circuit to perform the serving cell measurement and the wake-up circuit to perform the serving cell measurement. When the terminal device crosses the boundary corresponding to the sixth threshold (that is, the cell quality of the serving cell measured by the terminal device using the wake-up circuit is greater than or equal to the fifth threshold), the terminal device starts to monitor the wake-up signal, and during this period of time, the terminal device uses the wake-up circuit to perform the serving cell measurement, and stops using the main circuit to perform the serving cell measurement.

[0412] Optionally, in an embodiment of the present application, the terminal device performs a first measurement on the serving cell, including: the terminal device receives a fifth reference signal, and determines the cell quality of the serving cell according to the fifth reference signal. Specifically, the terminal device determines the value of the measurement amount according to the fifth reference signal, wherein the measurement amount can be used to characterize the cell quality of the serving cell. As an example, the measurement amount includes at least one of the following: RSRP (such as SS-RSRP), RSRQ (such as SS-RSRQ), SINR.

[0413] As an example, the fifth reference signal is SSB. Based on this, the above measurement amount can be obtained according to the SSB measurement. For example, the terminal device can measure according to the PSS and / or SSS and / or PBCH DMRS in the SSB.

[0414] As an example, the terminal device receives the fifth reference signal using the primary circuit.

[0415] Optionally, in an embodiment of the present application, the terminal device performs a second measurement on the serving cell, including: the terminal device receives a sixth reference signal, and determines the cell quality of the serving cell based on the sixth reference signal. Specifically, the terminal device receives the sixth reference signal, and determines the cell quality of the serving cell based on the sixth reference signal. Specifically, the terminal device determines the value of the measurement amount based on the sixth reference signal, wherein the measurement amount can be used to characterize the cell quality of the serving cell. As an example, the measurement amount includes at least one of the following: RSRP (or LP-RSRP), RSRQ (or LP-RSRQ), SINR (or LP-SINR).

[0416] As an example, the sixth reference signal is LP-SS. Based on this, the above measurement amount can be obtained according to LP-SS measurement.

[0417] As an example, the modulation mode of the sixth reference signal is OOK or FSK. The modulation mode of the sixth reference signal is OOK, which can also be replaced by: in the time interval corresponding to the sixth reference signal, some time domain positions have energy, and some time domain positions have no energy.

"Main circuit" can also be replaced by "second module", or can also be replaced by "main link", or can also be replaced by "in the second state", or can also be replaced by "in the second mode".
