[0047] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0048] In order to improve the energy-saving performance of the device, the mobile communication terminal introduces a low power wake up receiver (LP WUR), or a low power wake up receiver, or a low power wake up receiving module. In the energy-saving state, the terminal turns on the low power receiver to listen for the low power wake up signal (LP-WUS) and turns off the main communication module (MR). When downlink data arrives, the network side device will send a wake up signal to the terminal. After the terminal listens to the wake up signal through the low power receiver, it triggers the main communication module from off to on after a series of judgments (at this time, the low power receiving module can enter the off state from the working state). The low power wake up receiving module can be turned on continuously or intermittently, and can receive the low power wake up signal when it is turned on. It can be seen that the link quality of the wake up signal transmission becomes the key to whether the main communication module can be successfully awakened.

[0049] In the RRM measurement related technology, RSRP measurement is the linear average of the power of a specific signal (first signal) on each resource element (RE), and RSRQ measurement is N*RSRP / RSSI, where the received signal strength indication (RSSI) is the linear average of the total received power of N physical resource blocks (PRBs) within the measurement bandwidth on a specific measured orthogonal frequency division multiplexing (OFDM) symbol. It can be seen that the measurement of RSRP and RSRQ is defined based on the frequency domain resource unit, and has high requirements on the function of the measurement module, resulting in a narrow range of applicability of the equipment for the measurement behavior of the communication system in the related technology. For example, it cannot be applied to low-power receivers that can only receive signals in the time domain.

[0050] Furthermore, since the measurement behavior of the communication system in the related technology cannot be applied to a low-power receiver that can only receive signals in the time domain, that is, even if the communication system in the related technology introduces LP-WUR, the periodic measurement of the communication system still relies entirely on the main communication module. The power saving gain brought about by the introduction of LP-WUR is limited, which makes the overall power consumption of the terminal higher.

[0051] Below, in combination with the accompanying drawings, the wireless resource measurement, configuration method, device, terminal, equipment, medium and program product provided in the embodiments of the present application are described in detail through some embodiments and their application scenarios.

[0052] Referring to FIG. 2 , FIG. 2 is a flowchart of a method for measuring wireless resources provided in an embodiment of the present application, which is used for a terminal. As shown in FIG. 2 , the method includes the following steps:

[0053] Step 201: The terminal receives a target signal;

[0054] Step 202: The terminal determines a first measurement value based on the received power of the target signal in at least one time unit within a first time unit set; wherein the first measurement value is a measurement value of a wireless resource.

[0055] In an embodiment of the present application, the above steps 201 and 202 can be understood as the terminal obtaining a first measurement value within a first time unit set, wherein the first measurement value is a measurement value of a wireless resource, and the first measurement value is determined based on the receiving power of at least one time unit within the first time unit set.

[0056] In an embodiment of the present application, the above-mentioned first time unit set or the first time unit in the first time unit set may be configured by a network side device (also referred to as a network node), or may be determined based on a preset rule.

[0057] The target signal used to obtain the first measurement value may be configured by the network-side device, or may be determined based on a preset rule.

[0058] In an embodiment of the present application, during the RRM process, the method by which the terminal obtains the measurement value (first measurement value) of the wireless resource is to obtain the measurement value for the time unit, which is different from the method of determining the measurement value of the wireless resource based on the frequency domain resource unit in the related art. In addition to being applicable to conventional time-frequency communication modules, the measurement process can also be further applied to devices that can only receive signals in the time domain, such as low-power receivers that can only receive signals in the time domain, thereby increasing the scope of application of the wireless resource measurement method. In particular, when the low-power receiver is used to obtain the first measurement value, the overall power consumption of the terminal can also be reduced.

[0059] It is understandable that the embodiments of the present application do not require the measurement device to have frequency domain signal processing capabilities, which is not intended to limit the capabilities of the measurement device. The terminal executing the above method can also determine the measurement value of the wireless resource based on the frequency domain resource unit.

[0060] Optionally, reference signal received power RSRP, reference signal received quality RSRQ, received signal strength indicator RSSI, signal to interference plus noise ratio SINR.

[0061] In an embodiment of the present application, the first measurement value includes at least one of the following: RSRP, RSRQ, RSSI, signal to interference plus noise ratio (SINR), or the first measurement value includes other measurement values ​​that can be used to reflect the quality of the wireless channel link. It can be understood that the calculation method of the above-mentioned first measurement value is different from the measurement value calculation method based on frequency domain resource units (such as RE) in the related art. The embodiment of the present application can be understood as the reference signal received power, reference signal received quality, received signal strength indication or signal to interference plus noise ratio calculated on the time domain unit, or other measurement values ​​calculated on the time domain unit that can be used to reflect the quality of the wireless channel link.

[0062] Optionally, the terminal receiving a target signal includes:

[0063] The terminal receives a target signal using a low-power receiver.

[0064] In an embodiment of the present application, the above step 201 can be performed by the low-power receiver of the terminal, and the above step 202 can be performed by the low-power receiver of the terminal, or by other signal processing devices other than the low-power receiver.

[0065] In the embodiment of the present application, the terminal obtains the first measurement value within the first time unit set, including:

[0066] The terminal uses a low power consumption receiver to obtain a first measurement value within a first time unit set.

[0067] It is understandable that the execution device or module of the embodiments of the present application is not limited to a low-power receiver, but may also be other devices or modules with wireless resource measurement requirements.

[0068] Optionally, in an embodiment of the present application, the low-power receiver may not have the ability to process frequency domain signals, or may not have the ability to perform FFT and process the frequency domain signals output by the FFT. Alternatively, the low-power receiver may have the ability to process frequency domain signals, or may have the ability to perform FFT and process the frequency domain signals output by the FFT. In other words, the low-power receiver may at least have the ability to process time domain signals.

[0069] In order to further obtain power-saving gains in the LP-WUR scenario, the embodiment of the present application utilizes low-power reception to offload the measurement tasks of the main communication module, so that the low-power receiver can effectively measure the low-power signal and judge the link quality.

[0070] Optionally, under a specific channel quality condition (which may be the channel quality measured by the main communication module), that is, when the channel quality is good, the terminal uses the low-power receiver to obtain the first measurement value within the first time unit set. Optionally, the user equipment (UE) may rely entirely on the low-power receiver for measurement, or the low-power receiver performs measurement and the main communication module performs RRM measurement at a longer time interval.

[0071] Optionally, the low-power receiver includes at least one of the following types of low-power receivers:

[0072] A first type low-power receiver, wherein the first type low-power receiver has an ability to demodulate a first type of signal and does not have an ability to demodulate a second type of signal;

[0073] a second type of low-power receiver, wherein the second type of low-power receiver has the ability to demodulate a second type of signal;

[0074] The first type of signal includes an On-Off Keying (OOK) signal, and the second type of signal includes a complex signal sequence.

[0075] In the embodiments of the present application, the first type of low-power receiver has the ability to demodulate the first type of waveform, but does not have the ability to demodulate the second type of waveform. The second type of low-power receiver has the ability to detect the second type of waveform. Whether the second type of low-power receiver can demodulate the first type of waveform is not used as a basis for classification of the second type of low-power receiver. In other words, the second type of low-power receiver may have the ability to demodulate the first type of waveform, or may not have the ability to demodulate the first type of waveform.

[0076] The first type of low-power receiver also includes multiple types of receivers, including receivers based on RF envelope detection (exemplarily shown in part (a) of FIG3 ), receivers based on IF envelope detection (exemplarily shown in part (b) of FIG3 ), or receivers based on zero-IF baseband envelope detection (exemplarily shown in part (c) of FIG3 ). These low-power receiver structures typically have low power consumption and can at least be used to demodulate on-off keying (OOK) signals. They can include an OOK-based wake-up signal LP-WUS and an OOK-based synchronization signal, a low-power synchronization signal (LP-SS). The first type of low-power receiver can acquire synchronization, perform measurements, or receive wake-up notifications through simple energy detection and subsequent possible sequence detection and identification processes. These low-power receiver structures can add a module for demodulating frequency-shift keying (FSK) signals to support FSK signal demodulation.

[0077] The first type of signal includes at least an on-off keying signal, and the first type of signal does not include a complex signal sequence. The on-off keying signal may be a specific on-off keying sequence (OOK sequence), wherein each bit of the sequence is an on-off keying symbol. The specific on-off keying sequence may be at least one of a preset on-off keying sequence, a protocol-agreed on-off keying sequence, and an on-off keying sequence configured by a network-side device.

[0078] Optionally, the first type of signal may be an LP-SS signal, or may be at least part of an LP-WUS signal.

[0079] The second type of low-power receiver supports the detection of complex signal sequences, for example, the detection of Orthogonal Frequency Division Multiplexing (OFDM) signals, and the structure of at least some modules is different from that of the first type of low-power receiver. For example, as shown in part (d) of Figure 3, the second type of low-power receiver can process the real and imaginary signals separately, and the signal processing can be sequence correlation processing. As shown in part (e) of Figure 3, the second type of low-power receiver includes a low-power receiver detection module based on time domain correlation (without Fast Fourier Transform (FFT)) that can be used for OFDM signal reception.

[0080] The power consumption of the second type of low power receiver is generally higher than that of the first type of low power receiver, but lower than that of the main communication module.

[0081] Optionally, the complex signal sequence includes at least one of the following:

[0082] A first OFDM sequence, wherein the first OFDM sequence is an OFDM sequence agreed upon in a protocol or an OFDM sequence configured by a network-side device;

[0083] OFDM sequence modulated on the OOK signal;

[0084] Primary Synchronization Signal (PSS) in the synchronization signal block SSB;

[0085] Secondary Synchronization Signal (SSS) in SSB;

[0086] Demodulation Reference Signal (DMRS) in SSB;

[0087] a second OFDM sequence, wherein the second OFDM sequence is a PSS of one or more SSBs in the first SSB set;

[0088] a third OFDM sequence, wherein the third OFDM sequence is an SSS of one or more SSBs in the first SSB set;

[0089] a fourth OFDM sequence, wherein the fourth OFDM sequence is a DMRS of one or more SSBs in the first SSB set;

[0090] a fifth OFDM sequence, wherein the fifth OFDM sequence is a PSS of one or more SSBs outside the first SSB set;

[0091] a sixth OFDM sequence, wherein the sixth OFDM sequence is an SSS of one or more SSBs outside the first SSB set;

[0092] a seventh OFDM sequence, wherein the seventh OFDM sequence is a DMRS of one or more SSBs outside the first SSB set;

[0093] The first SSB set is an SSB set used by the main receiver of the terminal for radio resource management RRM measurement in the radio resource control RRC idle state, wherein the main receiver is different from the low power consumption receiver.

[0094] In an embodiment of the present application, the signal monitored by the second type of low-power receiver includes at least a signal based on an OFDM waveform. The signal monitored by the second type of low-power receiver includes an OFDM-based wake-up signal LP-WUS, for example, the OFDM signal is an OFDM sequence modulated on an OOK signal. The signal monitored by the second type of low-power receiver may also include an OFDM-based synchronization signal, such as a PSS, SSS, DMRS or Tracking Reference Signal (TRS) signal in the NR system of the related art, or a Channel State Information Reference Signal (CSI-RS) signal, etc.

[0095] It is understandable that the OFDM signal can be the same as the NR or LTE OFDM signal in the frequency domain, but when the low-power receiver may only have the ability to demodulate in the time domain, as shown in part (b) of Figure 3, the low-power receiver and the main communication module receive the OFDM signal in different ways.

[0096] In this embodiment of the present application, the second type of signal at least includes a complex signal sequence.

[0097] Optionally, the complex signal sequence is an OFDM sequence.

[0098] Optionally, the complex signal sequence is a specific OFDM sequence, and the above-mentioned specific OFDM sequence is at least one of a preset OFDM sequence, a protocol-agreed OFDM sequence, and an OFDM sequence configured by a network-side device. For example, the OFDM sequence is a complex sequence determined by at least one of the following or a sequence determined by multiplying real or complex sequences generated by at least two of the following: an M sequence, a ZC sequence, a gold sequence, a Constant Amplitude Zero Auto Correlation (CAZAC) sequence. For another example, each element of the OFDM sequence in the frequency domain must satisfy a point in a constellation diagram belonging to a specific modulation method, for example, the frequency domain samples of the OFDM sequence all satisfy the constellation diagram of binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 16-quadrature amplitude modulation (QAM), 64QAM or 256QAM modulation.

[0099] Optionally, the complex signal sequence is an OFDM sequence modulated on an OOK signal.

[0100] Optionally, the time-frequency resource where the complex signal sequence is located does not carry an OOK signal.

[0101] Optionally, the OFDM sequence is at least one of PSS, SSS and DMRS in SSB.

[0102] Optionally, the OFDM sequence is the PSS and / or SSS of one or more SSBs in the SSB set for RRM measurement of the primary receiver in the Radio Resource Control (RRC) idle state, or the OFDM sequence may not belong to the SSB set for RRM measurement of the primary receiver in the RRC idle state.

[0103] Optionally, the OFDM sequence is a PSS and / or SSS of a non-cell-defining SSB (NCD-SSB) or a cell-defined SSB (CD-SSB).

[0104] Optionally, the SSB is a non-cell-defined SSB or a cell-defined SSB.

[0105] In the embodiment of the present application, the SSB corresponding to the above-mentioned complex signal sequence may be a non-cell-defined SSB or a cell-defined SSB.

[0106] In an embodiment of the present application, the signal types that can be detected or demodulated by the low-power receiver are classified, wherein the first type of signal may be an On-Off-Keying (OOK) signal, and the second type of signal may be a complex signal sequence.

[0107] In other words, the signal (target signal) received by the terminal for obtaining the first measurement value can be divided into a first type of signal and a second type of signal. The classification of the first type of signal and the second type of signal can be understood as classification based on the transmission method of the target signal or classification based on the waveform of the target signal.

[0108] Optionally, the target signal includes at least one of a first signal and a second signal;

[0109] The first signal includes a reference signal for obtaining a first measurement value, and the second signal includes at least one of interference and noise.

[0110] In the embodiment of the present application, the terminal obtains the first measurement value within the first time unit set, including:

[0111] Acquiring, by the terminal, the first measurement value based on at least one of a received power of the first signal and a received power of the second signal in the first set of time units;

[0112] The first signal includes a reference signal for obtaining a first measurement value, and the second signal includes at least one of interference and noise.

[0113] In an embodiment of the present application, the target signal may include at least one of a first signal and a second signal, and the terminal determines the first measurement value based on the received power of at least one of the first signal and the second signal in a time unit.

[0114] Exemplarily, the first signal may be used to measure RSRP, the second signal may be used to measure RSSI, and the first signal and the second signal may be used to measure RSRQ (RSRQ=RSRP / RSSI).

[0115] Optionally, the type of the first signal is determined based on a transmission type of the first signal or a signal type of the first signal;

[0116] According to a transmission type of the first signal, the first signal includes at least one of a first type signal and a second type signal, the first type signal includes an on-off keying (OOK) signal, and the second type signal includes a complex signal sequence;

[0117] Alternatively, depending on the signal type of the first signal, the first signal includes at least one of a low power synchronization signal LP-SS, a low power wake-up signal LP-WUS, and SSB.

[0118] In the embodiment of the present application, the first signal is an optional target signal. Depending on the transmission type of the first signal, the first signal includes at least one of a first type signal and a second type signal.

[0119] The first signal includes at least one of the following: a specific signal based on the first type of signal, a specific signal based on the second type of signal. Alternatively, the first signal includes at least one of the following: a specific signal for a first type of low-power receiver, a specific signal for a second type of low-power receiver.

[0120] The first signal, serving as a reference signal, includes at least one of LP-SS, LP-WUS, and SSB. LP-SS, LP-WUS, and SSB are different signal types. It can be understood that the type of the first signal can be determined to include at least one of LP-SS, LP-WUS, and SSB based on the signal type of the first signal. LP-SS and LP-WUS are low-power signals.

[0121] It can be understood that the type of the first signal is determined based on the transmission type or signal type of the first signal, that is, there are two classification logics.

[0122] Different types of low-power receivers can demodulate different waveforms (first type signals and second type signals), but the types of signals that can be demodulated (LP-SS and LP-WUS) may be the same. For example, the first type of low-power receiver can receive LP-SS and LP-WUS; the second type of low-power receiver can receive LP-SS and LP-WUS. A signal type of a first signal (such as LP-SS or LP-WUS) may include both the first type signal and the second type signal. For example, LP-SS carries both OOK signals and complex signal sequences. The first type of receiver receives the OOK signal in the LP-SS, and the second type of receiver receives the complex signal sequence in the LP-SS. Optionally, the second type of receiver can also receive OOK signals. In this case, it can be considered that the processing method is the same as that of the first type of receiver.

[0123] The signal types measured by the first type of low power receiver and the second type of low power receiver may also be different. For example, the first type of low power receiver can be measured based on LP-SS, and the second type of low power receiver can be measured based on SSB.

[0124] Optionally, the second signal includes at least one of a first type signal and a second type signal.

[0125] In the embodiment of the present application, the second signal is an optional target signal. Depending on the transmission type of the second signal, the second signal includes at least one of the first type signal and the second type signal.

[0126] In the embodiment of the present application, different types of first signals have different time domain resources;

[0127] Different types of first signals have different frequency domain resources;

[0128] Different types of second signals have different time domain resources;

[0129] Different types of second signals have different frequency domain resources;

[0130] Or, the time domain resources of different types of first signals are the same;

[0131] The frequency domain resources of different types of first signals are the same;

[0132] The time domain resources of different types of second signals are the same;

[0133] The frequency domain resources of different types of second signals are the same;

[0134] Or, the second signal frequency domain resources of the same type of signals are the same;

[0135] The time domain resources of the second signals of the same type of signals are the same or different.

[0136] The above-mentioned different types of first signals may refer to between the first signal of the first type signal and the first signal of the second type signal, and different types of second signals may refer to between the second signal of the first type signal and the second signal of the second type signal; then, the same type of first signal may be multiple first signals that are all first type signals, or multiple first signals that are all second type signals; the same type of second signal may be multiple second signals that are all first type signals, or multiple second signals that are all second type signals.

[0137] Alternatively, different types of first signals may refer to LP-SS, LP-WUS, and SSB in pairs, and the same type of first signals may be multiple LP-SSs, or LP-WUSs, or multiple SSBs.

[0138] Optionally, the first time unit set or the first time unit in the first time unit set is determined according to a predefined rule;

[0139] Alternatively, the first time unit set or the first time unit in the first time unit set is determined according to the configuration of the network side device.

[0140] In an embodiment of the present application, the time unit set includes one or more time units, and the time unit in the time unit set or time unit combination used to obtain the first measurement value can be configured by the network side device or determined according to a pre-set rule.

[0141] Optionally, the first time unit set satisfies at least one of the following:

[0142] The first set of time units or the first time unit includes at least one time unit carrying a first signal;

[0143] The first set of time units or the first time unit includes at least one time unit carrying a second signal;

[0144] In a case where the network side device is not configured with the first time unit set or the first time unit, the first time unit set or the first time unit is determined according to the time unit of the first signal;

[0145] In a case where the network side device is not configured with the first time unit set or the first time unit, the first time unit set or the first time unit is determined according to the time unit of the second signal;

[0146] The first time unit set or the first time unit is determined according to the type of the low power receiver;

[0147] The first time unit set or the first time unit is determined according to a type of the first signal.

[0148] In an embodiment of the present application, the time unit set includes at least one time unit that carries a specific signal (first signal) for obtaining a first measurement value; if the network node side device is not configured with the time unit set or time unit, the time unit set and time unit are determined according to the time unit of the specific signal for obtaining the first measurement value;

[0149] The specific signal uses a first waveform (first type signal) and / or a second waveform (first type signal).

[0150] The terminal determines the time unit, the time unit set, and the specific signal based on the low-power receiver type and / or the type of the measured signal. As described in the previous embodiment, the type of the first signal can be determined based on the transmission type of the first signal or the signal type of the first signal. The first time unit set or the first time unit is determined based on the type of the first signal. It can be understood that a class of the first time unit set or the first time unit can be determined based on the first type of signal, and a class of the first time unit set or the first time unit can be determined based on the second type of signal.

[0151] For example, the terminal uses a first type of low-power receiver to obtain a first measurement value based on a first type of signal within an A time unit set / A time unit; the terminal uses a second type of low-power receiver to obtain a first measurement value based on a second type of signal within a B time unit set / B time unit.

[0152] Alternatively, a class of the first time unit set or the first time unit can be determined according to LP-SS, a class of the first time unit set or the first time unit can be determined according to LP-WUS, and a class of the first time unit set or the first time unit can be determined according to SSB.

[0153] For example, the terminal obtains a first measurement value based on LP-SS in the C time unit set / C time unit; the terminal obtains a first measurement value based on LP-WUS in the D time unit set / D time unit; the terminal obtains a first measurement value based on SSB in the E time unit set / E time unit.

[0162] Time unit configured on the network side device.

[0163] In the embodiment of the present application, the time unit may be an OOK ON symbol in a specific signal;

[0164] The time unit may also be the symbol of OOK OFF in a specific signal;

[0165] The time unit may also be an OOK symbol / OFDM symbol where a specific signal is located;

[0166] The time unit is other time units in the time unit set except the time window where the specific signal is located, for example, a time unit for measuring RSSI.

[0167] The time unit is a time unit configured by the network node.

[0168] Optionally, the time unit configured by the network-side device includes at least one of the following:

[0169] a first sub-time unit, wherein the first sub-time unit includes a subset of the second time unit;

[0170] a second sub-time unit, wherein the second sub-time unit includes time units other than the second time unit;

[0171] The second time unit is a time unit configured by the network side device for the main receiver of the terminal for RRC idle state RRM measurement.

[0172] In the embodiment of the present application, the above-mentioned sub-time unit is used to represent a certain type of first time unit.

[0173] In an embodiment of the present application, if the time unit is a time unit configured by the network node, the time unit is a subset of the time unit for which the network node configures the main receiver for idle state RRM measurement, or the time unit does not belong to the set of time units for which the network node configures the main receiver for idle state RRM measurement.

[0188] Among them, the first frequency domain resource is the frequency domain resource configured by the network side device or the frequency domain resource agreed upon by the protocol.

[0189] In an embodiment of the present application, the terminal obtains the first measurement value within a time unit set, which also includes the terminal obtaining the first measurement value within the time unit set on a frequency domain resource configured by the network or agreed upon by the protocol.

[0190] Optionally, the first frequency domain resource bandwidth includes a frequency domain resource bandwidth for measuring a first signal; wherein the first signal is a reference signal in the target signal used to obtain the first measurement value. In this embodiment of the present application, the terminal uses the first frequency domain resource to determine the first measurement value based on the received power of the target signal in at least one time unit within the first time unit set, including:

[0198] The terminal determines the first measurement value according to the received power.

[0199] Optionally, M1=M2, or M1 / M2=L1 / L2, where L1 is the number of OOK ON symbols of the target signal, and L2 is the number of OOK OFF symbols of the target signal.

[0200] In the embodiment of the present application, the bandwidth of the frequency domain resources includes the bandwidth of the frequency domain resources of the specific signal used for measurement.

[0201] To facilitate understanding, several specific examples are provided below.

[0202] Example 1

[0203] Taking the first type of signal as an OOK signal as an example, the terminal uses the first type of low-power receiver to measure based on the first type of signal, which can also be applied to other types of low-power receivers with measurement capabilities based on the first type of signal.

[0204] The first measurement value is the received power based on a specific signal (OOK synchronization signal), which is recorded as RSRP. The OOK synchronization signal can be a periodically transmitted synchronization signal, referred to as LP-SS in this example. Or the OOK synchronization signal can also be a non-periodically transmitted synchronization signal, such as a preamble in a low-power wake-up signal (LP-WUS). The time-frequency domain resources and code domain resources (i.e., OOK sequence, an OOK sequence consists of L OOK ON and OOK OFF symbols) of the OOK-based synchronization signal can be predefined by protocol and / or network configured.

[0205] The time unit used by the terminal to measure RSRP using the first type of low-power receiver is an OOK ON symbol (also called OOK ON code chip, described as symbols below) in the OOK sequence of the synchronization signal. The time unit set for the first type of low-power receiver to measure RSRP includes all OOK ON symbols in the OOK sequence of the synchronization signal. The terminal linearly averages the power of the specific signal on all time units in the time unit set to obtain the first measurement value. Optionally, the specific signal power on the OOK ON symbol can be obtained based on the received signal power on the OOK ON symbol and the noise / interference power obtained on the OOK OFF symbol. For example, the received signal power on the OOK ON symbol is P3, and the average noise / interference power obtained on the OOK OFF symbol is P1, then the specific signal power on the OOK ON symbol is P3-P1.

[0206] Alternatively, the terminal uses a first type of low-power receiver to measure RSRP, and the time unit used is each OOK symbol in the OOK sequence of the synchronization signal, that is, OOK ON and OOK OFF symbols are not distinguished. The terminal multiplies the received signal on each time unit in the time unit set with the local OOK sequence, adds the results, and then performs linear averaging to obtain the first measurement value. The values ​​of each element of the OOK ON and OOK OFF symbols of the local OOK sequence are 1 and -1 respectively. This ±1 calculation method is equivalent to the aforementioned P3-P1 calculation method.

[0207] The terminal linearly averages the power of the specific signal across all time units within the set of time units, obtaining a first measurement value with a temporal granularity of one OOK symbol. In a specific implementation, one OOK symbol may correspond to multiple time sampling points. Therefore, the linear average of the power at the OOK symbol level is the sum of the measurement results at all time sampling points for one OOK symbol.

[0208] Alternatively, the terminal linearly averages the power of the specific signal on all time units in the set of time units, and the obtained first measurement value has a granularity in time of M OOK symbols or one OFDM symbol, for example, M is an integer number of OOK symbols that can be mapped to one OFDM symbol. Then, the linear average of the power at the OFDM symbol level is M times the average specific signal power at the OOK symbol level, for example, the average specific signal power at the OOK symbol level multiplied by M. Considering that the time granularity of the RSRP of the main receiver is one OFDM symbol, or the time granularity of the measurement of the RSRP based on SSB of the second type of low-power receiver is usually also one OFDM symbol, the first type of low-power receiver uses the same time granularity, which can make it easier to compare the measurement results of different receivers.

[0209] Alternatively, the terminal linearly averages the power of the specific signal in all time units in the time unit set, and the time granularity of the obtained first measurement value is a time sampling point, where the time length of the time sampling point is determined by the sampling rate.

[0210] Optionally, the time resources actually measured by the terminal may be all or part of all the time units in the time unit set, but need to meet the measurement accuracy requirement.

[0211] Since the low-power receiver receives the signal in the time domain, the measurement result of the first measurement value is the total power over the entire measurement bandwidth. Optionally, for different terminals, the frequency domain resources actually used by the terminal for measurement (referred to as the second frequency domain resources) may be different. For example, the frequency domain resources of the synchronization signal LP-SS are the 10th to 20th PRBs. According to one implementation, the frequency domain resources actually measured by the terminal, i.e., the second frequency domain resources, include all frequency domain resources of the LP-SS signal. According to another implementation, the frequency domain resources actually measured by the terminal, i.e., the second frequency domain resources, include at least part of the frequency domain resources of the LP-SS signal. For example, the frequency domain resources actually measured by the terminal are the 15th to 20th PRBs, or the frequency domain resources actually measured by the terminal are the 15th to 21st PRBs (for example, due to the accuracy of the filter, the resources actually measured by the terminal may not be completely aligned with the frequency domain resources of the LP-SS signal). It is not difficult to see that the actual measurement bandwidth of the terminal is different, and the measurement results may be different. For example, the actual measured power of the 15th to 20th PRB is 6 / 11 of the actual measured power of the 10th to 20th PRB. In order to reduce the impact of different second frequency domain resources used by different terminals, it is necessary to normalize the measurement results to a predefined or base station configured bandwidth, that is, the first measurement result is the linear average of the power over the normalized bandwidth. The bandwidth used for normalization can be determined in at least one of the following ways:

[0212] (1) The given bandwidth is the bandwidth of the frequency domain resources of the first signal.

[0213] Optionally, the measurement bandwidth of the second frequency domain resource is a bandwidth of a specific signal for measuring RSRP, such as a bandwidth of an LP-SS. The first measurement value=a measurement value of the terminal on the second frequency domain resource.

[0214] Optionally, if the bandwidth of the second frequency domain resource is different from the bandwidth of the LP-SS signal, the first measurement value = the terminal's measurement value on the second frequency domain resource / (the bandwidth of the second frequency domain resource / the bandwidth of the LP-SS signal). For example, the frequency domain resources of the first LP-SS signal are the 10th to 20th PRBs. The second frequency domain resources are the 15th to 20th PRBs. Therefore, the first measurement value = the power measured by the terminal on the second frequency domain resource / (6 / 11). That is, the first measurement value is the linear average value over the bandwidth of the frequency domain resource of the first signal.

[0215] (2) The given bandwidth is the bandwidth of one PRB.

[0216] Optionally, the first measurement value=the measurement value of the terminal on the second frequency domain resource ÷N, where N is the number of PRBs corresponding to the second frequency domain resource.

[0217] For example, the frequency domain resources of the first LP-SS signal are the 10th to 20th PRBs. The second frequency domain resources are the 15th to 20th PRBs. Therefore, the first measurement value = the power measured by the terminal on the second frequency domain resource divided by 6. That is, the first measurement value is the linear average value over the bandwidth of the PRBs of the frequency domain resources of the first signal.

[0218] (3) The given bandwidth is the bandwidth of one RE.

[0219] Optionally, the first measurement value=the measurement value of the terminal on the second frequency domain resource ÷ N0, where N0 is the number of REs corresponding to the bandwidth of the second frequency domain resource, and N0=12*N.

[0220] For example, the frequency domain resources of the first LP-SS signal are the 10th to 20th PRBs. The second frequency domain resources are the 15th to 20th PRBs. Therefore, the first measurement value = the power measured by the terminal on the second frequency domain resource divided by 72. That is, the first measurement value is the linear average value of the REs of the frequency domain resource of the first signal over the bandwidth.

[0221] (4) The given bandwidth is a bandwidth of N1 Hz, where N1 is a predefined value, for example, N1=1, or a value configured by the base station.

[0222] Optionally, the first measurement value = the measurement value of the terminal on the second frequency domain resource) ÷ (N2 ÷ N1), where the bandwidth of the second frequency domain resource is N2 Hz. The first measurement value is a linear average value over the N1 Hz bandwidth of the frequency domain resource of the first signal.

[0223] This is different from the RSRP measurement in the NR system. The RSRP measurement in the NR system can perform sequence correlation of specific signals in the frequency domain to obtain the power on each RE within the bandwidth of the specific signal. The low-power receiver measures the specific signal in the time domain, obtains the total power over the actual measurement bandwidth, and normalizes it to the power over the given bandwidth. The bandwidth actually measured by the low-power receiver can be based on different terminal implementations, but no matter which implementation method is adopted, the measurement results must meet the predefined measurement accuracy requirements. Optionally, the predefined measurement accuracy requirements are determined based on the first frequency domain resources and / or the given normalized bandwidth.

[0224] Optionally, the first measurement value is a ratio of the received power RSRP based on a specific signal (OOK synchronization signal) to the received signal strength (denoted as RSSI). The first measurement value is recorded as RSRQ. The terminal uses the first type of low-power receiver to measure RSRP, which can be obtained according to the method described above. The time unit used by the terminal to measure RSSI using the first type of low-power receiver can be determined according to at least one of the following methods:

[0225] 1) The time unit is an OOK OFF symbol in a specific signal for measuring RSRP, and the time unit set for measuring RSSI by the first type of low-power receiver includes all OOK OFF symbols in the specific signal;

[0226] 2) The time unit is an OOK ON symbol in the specific signal for measuring RSRP, and the time unit set for measuring RSSI by the first type of low-power receiver includes all OOK ON symbols in the specific signal;

[0227] 3) The time unit is each OOK symbol in the specific signal for measuring RSRP, that is, OOK ON and OOK OFF symbols are not distinguished. The time unit set for measuring RSSI by the first type of low-power receiver includes all OOK ON and OOK OFF symbols in the specific signal.

[0228] 4) The time unit is a time unit configured by the network node. The network node may configure the OOK ON symbol in the specific signal for measuring RSRP as the time unit, or the OOK OFF symbol in the specific signal for measuring RSRP as the time unit, or each OOK symbol in the specific signal for measuring RSRP as the time unit, or any one or more OOK symbols in the specific signal for measuring RSRP as the time unit;

[0229] Alternatively, the network node indicates that some OOK symbols in a specific signal for measuring RSRP are the time unit, for example, one or more OOK symbols in an OOK synchronization sequence having a length of L are indicated by an L bit as the time unit;

[0230] Alternatively, the network node indicates the time unit. For example, the network node may indicate one or more time units that do not contain the specific signal for measuring RSRP. In some scenarios, the time or frequency domain resources of the low-power signal may be coordinated between cells to ensure the reception performance of the low-power signal. However, when the main receiver receives the signal (non-low-power signal), it may receive interference from the signal of the adjacent cell. In order to truly reflect the link quality of the main receiver, the network node may configure the time unit of RSSI or the time unit of noise and interference in SINR to an OFDM symbol that does not contain a low-power signal (for example, LP-SS and / or LP-WUS). The following description is for convenience, only RSSI is taken as an example. The method applicable to RSSI can also be applied to the measurement of noise and interference in SINR.

[0231] The set of time units for measuring RSSI by the first type of low power consumption receiver includes all the time units.

[0232] Alternatively, the protocol may predefine multiple possible configurations, and the network node may indicate one of the configurations, for example, as shown in Table 1.

[0233] Table 1

[0234] For example, the specific reference signal is at least one of LP-SS, LP-WUS, or SSB for LP-WUR RRM measurement.

[0235] For example, the specific reference signal is a reference signal configured by the network node for measuring RSRP.

[0236] If the network node does not indicate, the time unit is a time unit predefined according to a protocol, such as an OOK OFF symbol in a reference signal used to measure RSRP.

[0237] The terminal linearly averages the power of the specific signal on all the time units in the time unit set, and the obtained first measurement value has a time granularity of one OOK symbol. Alternatively, the terminal linearly averages the power of the specific signal on all the time units in the time unit set, and the obtained first measurement value has a time granularity of M OOK symbols or one OFDM symbol. Alternatively, the terminal linearly averages the power of the specific signal on all the time units in the time unit set, and the obtained first measurement value has a time granularity of one time sampling point, where the time length of the time sampling point is determined by the sampling rate.

[0238] Optionally, the time resource actually measured by the terminal may be all or part of the time units in all the time units in the time unit set, but needs to meet the measurement accuracy requirements. For example, LP-SS includes 8 OOK ON and 8 OOK OFF symbols. According to 2), the time unit is an OOK ON symbol in the specific signal for measuring RSRP, and the time unit set for measuring RSSI by the first type of low-power receiver includes all OOK ON symbols in the specific signal. The OOK ON symbol actually measured by the terminal may be part of the 8 OOK ON symbols, for example, 4 OOK ON symbols, and the power measured on the 4 OOK ON symbols is linearly averaged.

[0239] If the measured time resources can include OOK ON symbols and OOK OFF symbols, for example, according to 3), the time unit set for the first type of low-power receiver to measure RSSI includes all OOK ON and OOK OFF symbols of LP-SS, and the OOK ON symbols and OOK OFF symbols actually measured by the terminal can be part of all OOK ON and OOK OFF symbols of LP-SS. It is not difficult to see that when the ratio of the number of OOK ON symbols and the number of OOK OFF symbols actually measured by the terminal is different, the measurement results may be different. For example, if the terminal actually measures the linear average of the power of 4 OOK ON symbols and 4 OOK OFF symbols, or actually measures the linear average of the power of 8 OOK ON symbols and 1 OOK OFF symbol, the RSSI results will be different. Since only interference and noise are measured in OOK OFF symbols, while interference, noise and useful signals are measured in OOK ON symbols, the RSSI value based on more OOK ON symbols is larger. (1) In order to reduce the change of RSSI caused by different time resources used by different terminals, it is necessary to limit the number of OOK ON and OOK OFF used by the terminal to measure RSSI. The OOK ON and OOK OFF symbols actually measured by the terminal can be limited to all OOK symbols of a specific signal using at least one of the following methods. For example, if the specific signal is LP-SS, LP-SS includes 8 OOK ON and 8 OOK OFF symbols. The terminal actually measures these 8 OOK ON and 8 OOK OFF symbols.

[0240] (2) The number of OOK ON symbols M1 and the number of OOK OFF symbols M2 actually measured by the terminal satisfy at least one of the following predefined relationships:

[0241] M1=M2;

[0242] M1 / M2=L1 / L2, where L1 is the number of OOK ON symbols of LP-SS and L2 is the number of OOK OFF symbols of LP-SS;

[0243] M1-M2≤Th1, where Th1 is a predefined integer;

[0244] M1≤Th2 and / or M2≤Th3, or, M1≥Th4 and / or M2≥Th5, wherein Th2, Th3, Th4, Th5 are predefined integers.

[0245] Since the low power receiver monitors in the time domain, the measurement result of the first measurement value is the total power over the entire measurement bandwidth. Preferably, the measurement bandwidth is the bandwidth of the reference signal for measuring RSRP.

[0246] If the time / frequency domain resource granularity of RSRP and RSSI in RSRQ is the same, then RSRQ = RSRP / RSSI. If the time / frequency domain resource granularity of RSRP and RSSI in RSRQ is different, then RSRQ = Nr*RSRP / RSSI, where Nr is determined according to the ratio of the time / frequency domain resource granularity of RSSI and RSRP. For example, RSRP is the average value at the OOK symbol level, RSSI is the average value at the OFDM symbol level, and the number of OOK symbols that can be mapped to an OFDM symbol time length is 4, then Nr = 4. For another example, RSRP is the measured value of a given bandwidth, the given bandwidth is one PRB, and RSSI is the measured value of the terminal measurement bandwidth, then Nr = N, where N is the number of PRBs corresponding to the measurement bandwidth.

[0247] RSSI is different from RSRP measurement. RSRP measurement results only include the power of the reference signal, while RSSI measurement results can include the power of all signal sources, such as signals from serving or non-serving cells on the same frequency, interference from cells on adjacent channels, noise, etc.

[0248] According to one embodiment of the present application, the first measurement value is RSSI, which can be implemented according to the method for measuring RSSI in the above embodiment.

[0249] In one scenario, the network node is configured with two specific signals for low-power receivers, corresponding to the reception of low-power receivers based on the first type of signal and the second type of waveform by the terminal, such as LP-SS and SSB based on NR OFDM. In one scenario, the network node is only configured with one specific signal for low-power receivers based on the first type of signal, such as LP-SS. In one scenario, the network node is configured with a specific signal for low-power receivers, and the specific signal consists of two waveforms, wherein the second type of signal is modulated on the first type of signal. The specific signal is also called a specific signal based on an overlaid OFDM sequence(s) over OOK symbol. In the above various scenarios, the first type of low-power receiver can sample the method of this embodiment based on OOK signal measurement.

[0250] Optionally, if the resource used for measurement is an uplink time slot or symbol, such as an uplink time slot or symbol determined according to the cell-common time division duplexing (TDD) uplink and downlink configuration configured in the system information, the terminal does not measure on the resource, or the first measurement result does not include the measurement result on the resource.

[0251] Example 2

[0252] Taking the second type of waveform as an OFDM waveform as an example, the terminal uses the second type of low-power receiver to perform measurements based on the second type of waveform, which can also be applied to other types of low-power receivers that have the ability to measure based on the second type of waveform.

[0253] The OFDM signal of the second type of waveform is a specific OFDM sequence.

[0254] Optionally, the time-frequency resource where the OFDM signal is located does not carry an OOK signal, as described in scenario 1 or scenario 2 below;

[0255] Optionally, the OFDM signal is an OFDM sequence modulated on an OOK signal, as described in Scenario 3 below.

[0256] The following describes how a terminal performs measurements based on an OFDM sequence according to different scenarios.

[0257] In one scenario (Scenario 1), the network node configures two reference signals for low-power receivers, corresponding to the terminal's reception of low-power receivers based on the first type of signal and the second type of waveform, such as LP-SS and NR OFDM-based SSB.

[0258] In one scenario (Scenario 2), the network node configures only one reference signal for reception by a low-power receiver based on the second type of waveform, such as SSB based on NR OFDM.

[0259] In scenarios 1 and 2, the time-frequency resources where the OFDM signal is located may not carry an OOK signal.

[0260] According to one implementation of the present application, the reference signal (OFDM sequence) is at least one of the PSS, SSS, and DMRS signals in the synchronization signal block SSB in the NR system, that is, an OFDM sequence defined in the frequency domain. The synchronization signal can be a CD-SSB, that is, an SSB that supports cell access, which contains information of the control resource set 0 (CORESET 0) configured for receiving system information, or an NCD-SSB, that is, an SSB that does not support cell access. The time-frequency domain resources and code domain resources of the reference signal (for example, the cell ID or SSB index used to determine the SSB sequence) can be predefined by protocol and / or configured by the network. The reference signal can be a subset of the SSB set used for RRM measurement of the primary receiver, or the reference signal may not belong to the SSB set used for RRM measurement of the primary receiver. For example, in the NR system of the related art, the network node configures the SSB measurement timing configuration (SMTC) and SSB information for RRM measurement in the system information for measurement of the primary receiver. Optionally, the network node may further configure the measurement time window information and SSB information for the second type of low power consumption receiver in the system information.

[0261] According to one embodiment of the present application, the first measurement value is the received power based on the reference signal (synchronization signal of the OFDM sequence), which is recorded as RSRP. Taking the structure of a typical second-type low-power receiver as an example, the receiver does not have an FFT module, so the real part and the imaginary part of the received specific signal are respectively subjected to OFDM sequence correlation detection in the time domain, as shown in Figures 3(a) to 3(e). In the case where the network node is configured with a frequency domain OFDM sequence, the receiver can determine the corresponding time domain OFDM sequence according to the frequency domain OFDM sequence configured by the network node, and use the corresponding time domain OFDM sequence determined according to the frequency domain OFDM sequence configured by the network node as the local time domain OFDM sequence, and use the local time domain OFDM sequence to perform correlation detection with the received time domain signal. Alternatively, in the case where the network node is configured with a time domain OFDM sequence, the receiver can determine the local time domain OFDM sequence according to the time domain OFDM sequence configured by the network node, and use the local time domain OFDM sequence to perform correlation detection with the received time domain signal.

[0262] The time unit used by the terminal to measure RSRP using the second type of low-power receiver is each OFDM symbol in which the reference signal is located. The time unit set for the second type of low-power receiver to measure RSRP includes all OFDM symbols of the reference signal. The terminal linearly averages the power of the reference signal over all time units in the time unit set to obtain the first measurement value. If the reference signal occupies only one OFDM symbol, the time unit is the same as the time unit set. Optionally, if the network node configures a time window for reception by the second type of low-power receiver, the time unit is the reference signal located within the time window.

[0263] The terminal linearly averages the power of the reference signal over all time units in the set of time units, and the obtained first measurement value has a temporal granularity of one OFDM symbol. Alternatively, the terminal linearly averages the power of the reference signal over all time units in the set of time units, and the obtained first measurement value has a temporal granularity of 1 / M OFDM symbols or one OOK symbol, where M is the number of integer OOK symbols that can be mapped to one OFDM symbol. Then, the linear average of the power at the OOK symbol level is 1 / M of the average specific signal power at the OFDM symbol level, for example, the average specific signal power at the OFDM symbol level divided by M. In some scenarios, the number of integer OOK symbols of LP-WUS and the number of OOK symbols of LP-SS that can be mapped to one OFDM symbol are different. According to one example, M is the number of integer OOK symbols of LP-WUS that can be mapped to one OFDM symbol, and according to another example, M is the number of integer OOK symbols of LP-SS that can be mapped to one OFDM symbol. The rules can be predefined by the protocol or configured by the network node. Alternatively, the terminal linearly averages the power of the reference signal over all time units in the time unit set, and the time granularity of the obtained first measurement value is a time sampling point, where the time length of the time sampling point is determined by the sampling rate.

[0264] Since the low-power receiver receives the signal in the time domain, the measurement result of the first measurement value is the total power over the entire measurement bandwidth. Preferably, the measurement bandwidth is the bandwidth of the reference signal. According to an example, the specific signal is SSS. The measurement bandwidth is the PRB or RE occupied by SSS. It is worth noting that the PRB occupied by SSS is only a part of the PRB occupied by SSB. As shown in Figure 5, SSB occupies 20 PRBs (a total of 240 REs), but SSS only occupies the middle 127 REs, and the frequency domain resources occupied by SSS and the frequency domain resources of PBCH in the symbol where SSS is located are separated by multiple REs. In order to avoid the influence of PBCH in the SSS symbol on the detection of SSS time domain signals, the measurement bandwidth of the first measurement value should try to avoid including the frequency domain resources where PBCH is located.

[0265] Alternatively, according to one implementation, when the measurement result of the first measurement value has a temporal granularity of one OFDM symbol, although it is measured over the entire measurement bandwidth, it is equivalent to the measurement result being the average power of a specific signal on the RE of each OFDM symbol.

[0266] According to one embodiment of the present application, the first measurement value is the ratio of the received power RSRP based on the reference signal (synchronization signal of the OFDM sequence) to the received signal strength (recorded as RSSI). The first measurement value is recorded as RSRQ. The terminal uses the second type of low-power receiver to measure RSRP, which can be obtained according to the method described above. The time unit used by the terminal to measure RSSI using the second type of low-power receiver can be determined according to at least one of the following methods:

[0267] 1) The time unit is all OFDM symbols in the reference signal used to measure RSRP.

[0268] If the network node configures a time window for low-power reception, then all the symbols are all symbols of a specific signal located within the time window.

[0269] Optionally, the protocol predefines the time window as at least one of the SMTCs configured in the system information for RRM measurement of the primary receiver.

[0270] Alternatively, the network node may independently configure the time windows for the primary receiver and the low power receiver.

[0271] 2) The time unit is at least one or all OFDM symbols in the time slot / subframe / half radio frame / radio frame where the reference signal for measuring RSRP is located.

[0272] For example, the specific signal occupies N1 (N1<14) symbols in a time slot, and the time unit is 14 OFDM symbols in the time slot.

[0273] 3) The time unit is at least one or all OFDM symbols in the time slot / subframe / half radio frame / radio frame where the reference signal for measuring RSRP is located, except for the symbol of the reference signal for measuring RSRP.

[0274] Optionally, the time unit is all OFDM symbols in the time slot where the reference signal for measuring the RSRP is located except for the symbol of the reference signal for measuring the RSRP.

[0275] Optionally, the time unit is at least one OFDM symbol other than the symbol of the reference signal for measuring RSRP in the time slot where the reference signal for measuring RSRP is located. The protocol does not limit the specific OFDM symbol, and the terminal can select it at its own discretion, only needing to ensure that the measurement accuracy requirement is met.

[0276] 4) The time unit is at least one or all OFDM symbols in the time slot / subframe / half radio frame / radio frame where the reference signal for measuring RSRP is located, except for the symbol where the SSB is located.

[0277] For example, although the reference signal used for the second type of low-power receiver is the SSS in the SSB, considering that the PSS and PBCH symbols in the SSB cannot truly reflect the load situation, all SSB symbols are not used for RSSI measurement.

[0278] 5) The time unit is an OFDM symbol other than a symbol of a reference signal used to measure the RSRP within a time window configured by the network node for low-power reception.

[0279] 6) The time unit is an OFDM symbol other than the symbol where the SSB is located within the time window configured by the network node for low-power reception.

[0280] 7) The time unit is a specific OFDM symbol within a time window configured by the network node for low-power reception.

[0281] Preferably, the configuration of the specific OFDM symbols within the time window predefined by the protocol is the same as the configuration of the OFDM symbols configured in the system information for RSSI measurement of the primary receiver. Alternatively, the network node can independently configure the specific OFDM symbols for RSSI measurement of the primary receiver and the low-power receiver.

[0282] According to one example, the protocol predefines a table of multiple possible OFDM conforming position configurations suitable for low power receivers and indicates one of the configurations.

[0283] According to another example, a table of multiple possible OFDM conforming position configurations applicable to primary reception RSSI measurement in the protocol pre-defined related art (e.g., Table 5.1.3-1 in the 3rd Generation Partnership Project (3GPP) standard TS 38.215) is also applicable to RSSI measurement of the second type of low-power receiver. The network can indicate one of the configurations for the primary receiver and one of the configurations for the second type of low-power receiver, respectively.

[0284] According to another example, the protocol predefines a table of multiple possible OFDM position configurations applicable to primary receiver RSSI measurement in related art, which is also applicable to RSSI measurement of the second type of low-power receiver. The network indicates one of the configurations for the primary receiver and the second type of low-power receiver.

[0285] 8) The time unit is a specific portion of a specific OFDM symbol within a time window configured by the network node for low power reception.

[0286] For example, the network node may configure one or more time subunits within one or more specific OFDM symbols, where the length of one time subunit is the time length of one OOK symbol.

[0287] 9) The time unit is an OOK OFF symbol in the preamble of the LP-SS or LP-WUS. The LP-SS or LP-WUS is the LP-SS or LP-WUS resource closest to the reference signal for measuring RSRP.

[0288] The terminal linearly averages the power of the reference signal on all time units in the time unit set, and the obtained first measurement value has a granularity of one OFDM symbol in time. Alternatively, the terminal linearly averages the power of the reference signal on all time units in the time unit set, and the obtained first measurement value has a granularity of 1 / M OFDM symbols or one OOK symbol in time, where M is the number of integer OOK symbols that can be mapped to one OFDM symbol. Alternatively, the terminal linearly averages the power of the reference signal on all time units in the time unit set, and the obtained first measurement value has a granularity of one time sampling point in time, where the time length of the time sampling point is determined by the sampling rate.

[0289] Because the low-power receiver monitors in the time domain, the measurement result of the first measurement value is the total power over the entire measurement bandwidth. Preferably, the measurement bandwidth is the bandwidth of the reference signal. According to one example, the reference signal is the SSS. The measurement bandwidth is the PRB or RE occupied by the SSS.

[0290] In one scenario (Scenario 3), a network node configures a reference signal for a low-power receiver. The reference signal consists of two waveforms, with the second waveform modulated on the first type of signal. This reference signal is also known as a reference signal based on overlaid OFDM sequence(s) over OOK symbols.

[0291] According to one embodiment of the present application, the first measurement value is based on the received power of the reference signal (modulated into the OFDM sequence in the OOK symbol of the LP-SS), which is recorded as RSRP. The time unit used by the terminal to measure RSRP using the second type of low-power receiver is an OOK ON symbol in the OOK sequence of the reference signal. In the OOK ON symbol, the terminal uses the second type of low-power receiver to measure the signal power of the OFDM sequence in the ON symbol. The time unit set for the second type of low-power receiver to measure RSRP includes all OOK ON symbols in the reference signal. The terminal linearly averages the power of the specific signal on all time units in the time unit set to obtain the first measurement value. Optionally, the time resource actually measured by the terminal can be a subset of all time units in the time unit set.

[0292] The terminal linearly averages the power of the reference signal on all time units in the time unit set, and the obtained first measurement value has a time granularity of one OOK symbol. Alternatively, the terminal linearly averages the power of the reference signal on all time units in the time unit set, and the obtained first measurement value has a time granularity of one OFDM symbol. Then, the linear average of the power at the OFDM symbol level is the sum of the powers of M OOK symbols. Alternatively, the terminal linearly averages the power of the reference signal on all time units in the time unit set, and the obtained first measurement value has a time granularity of one time sampling point, where the time length of the time sampling point is determined by the sampling rate. Since the low-power receiver monitors in the time domain, the measurement result of the first measurement value is the total power over the entire measurement bandwidth. Preferably, the measurement bandwidth is the bandwidth of the reference signal for measuring RSRP, such as the bandwidth of LP-SS. Similar to the method in Example 1, optionally, for different terminals, the frequency domain resources actually used by the terminal for measurement (referred to as the second frequency domain resources) may be different. To reduce the impact of different second frequency domain resources used by different terminals, the measurement results need to be normalized to a predefined or base station-configured bandwidth, that is, the first measurement result is the linear average of the power over the normalized bandwidth. For example, the measurement result may be normalized to the bandwidth of the LP-SS, or to the bandwidth of one PRB carrying the LP-SS, the bandwidth of one RE, or the bandwidth of N1 Hz.

[0293] According to one embodiment of the present application, the first measurement value is the ratio of the received power RSRP based on the reference signal (the OFDM sequence modulated into the OOK symbol of the LP-SS) to the received signal strength (denoted as RSSI). The first measurement value is denoted as RSRQ. The RSRP measurement by the terminal using the first type of low-power receiver can be obtained according to the method in Example 1 or the method described above in Example 2.

[0294] It is understandable that the descriptions about RSSI in the above examples 1 and 2 are actually applicable to measuring interference and noise in SINR.

[0295] For any of the above methods, if the time / frequency domain resource granularity of RSRP and RSSI in RSRQ is the same, then RSRQ = RSRP / RSSI. If the time / frequency domain resource granularity of RSRP and RSSI in RSRQ is different, then RSRQ = Nr*RSRP / RSSI, where Nr is determined based on the ratio of the time / frequency domain resource granularity of RSSI to RSRP. For example, RSRP is the average value of the RE granularity in the frequency domain at the OFDM symbol granularity in the time domain, and RSSI is the average value of the entire measurement signal bandwidth in the frequency domain at the OFDM symbol granularity in the time domain. Then Nr is the number of PRBs corresponding to the measurement signal bandwidth.

[0296] Optionally, the terminal may jointly determine the first measurement value based on the SSB and the LP-SS based on the overlaid OFDM sequence(s)over OOK symbol. When the terminal merges the measurement results of the two signals, it is necessary to ensure that the granularity of the linear average of the measurement results of the two signals in the time resources and frequency domain resources is the same. Preferably, the granularity of the linear average of the time resources and frequency domain resources of the first measurement value of the SSB is merged. For example, the time resource granularity of the first measurement value based on the SSB and the first measurement value based on the OFDM sequence modulated into the OOK symbol of the LP-SS are the same, but the frequency domain resource granularity is different. For example, one of the measurement results based on the SSB is the average of the RE, and the other is the average of the PRB. Then, the terminal needs to normalize the first measurement result of the LP-SS based on the overlaid OFDM sequence(s)over OOK symbol to the linear average of the power of one RE, and merge it with the measurement result based on the SSB to obtain the first measurement result. Optionally, when the terminal merges the measurement results of the two signals, it needs to consider the transmit power difference between the two reference signals. For example, if the power offset of the base station's LP-SS power relative to the power of the SSB power is P1, the terminal needs to convert the first measurement value of the LP-SS overlaid OFDM sequence(s)over OOK symbol according to the power offset value P1 and combine it with the first measurement value of the SSB. Optionally, if the first measurement value based on the SSB and the first measurement value of the LP-SS based on the overlaid OFDM sequence(s)over OOK symbol correspond to the same threshold, such as a threshold for determining entry or exit from low-power receiver operation, the terminal needs to convert the first measurement value of the LP-SS overlaid OFDM sequence(s)over OOK symbol according to the power offset value P1 and compare it with the threshold.

[0297] Preferably, if the resource used for measurement is an uplink time slot or symbol, such as an uplink time slot or symbol determined according to the cell-common TDD uplink and downlink configuration configured in the system information, the terminal does not measure on the resource, or the first measurement result does not include the measurement result on the resource.

[0298] In an embodiment of the present application, a terminal obtains a first measurement value within a first time unit set; wherein the first measurement value is a measurement value of a radio resource, and the first measurement value is determined based on the received power of at least one time unit within the first time unit set. The ability to obtain measurement values ​​for each time unit increases the applicability of the radio resource measurement method.

[0299] Referring to FIG. 4 , FIG. 4 is a flowchart of a method for configuring measurement of wireless resources provided in an embodiment of the present application, which is used for a network-side device. As shown in FIG. 4 , the method includes the following steps:

[0301] The first configuration information is used to configure resources for the terminal to obtain a first measurement value, the first measurement value is a measurement value of a wireless resource, and the first measurement value is determined according to the received power of at least one time unit in a first time unit set.

[0302] As shown in Figure 2, the time unit, the time unit set, and the signal for obtaining the first measurement value can be preset or configured by the network side device. The embodiment of the present application is described with respect to the configuration of the network side device (also referred to as a network node).

[0303] In the embodiment of the present application, the network node may be used to configure measurement resources for the terminal to obtain the first measurement value.

Its specific implementation can refer to the relevant description of the embodiment shown in Figure 1. To avoid repetition, this embodiment will not be repeated.

For example, when the first signal is configured as an OOK sequence, the time domain resources of the above-mentioned second signal are the time resources where the OOK OFF symbol in this OOK sequence is located.

[0312] The resources of the second signal may also be other resources other than the resources of the first signal.

[0331] In an embodiment of the present application, optionally, the above-mentioned network node can be configured with an SSB for the low-power receiver and an SSB for the main receiver respectively.

[0332] Optionally, the SSB is a non-cell-defined SSB or a cell-defined SSB.
