[0025] In a first aspect, an embodiment of the present disclosure provides a method for determining a measurement metric, the method comprising:

[0026] The network device determines the reference signal received power RSRP according to the low power synchronous LP-SS signal received by the user equipment in the continuous time-frequency resources.

[0027] In the above embodiment, the network device determines the RSRP based on the LP-SS signal received by the user equipment in the continuous time-frequency resources, which can further reduce the power consumption of the user equipment and obtain a higher power saving gain.

[0028] In conjunction with some embodiments of the first aspect, in some embodiments, the received power of the LP-SS signal in the first continuous time domain resource is determined based on whether the LP-SS signal carries information in the first continuous time domain resource;

[0029] The RSRP is determined according to the received power of the LP-SS signal in the first continuous time domain resource.

[0030] In the above embodiment, the RSRP can be accurately determined by determining the received power of the LP-SS signal in the first continuous time domain resource based on whether the LP-SS signal carries information or not in the first continuous time domain resource, and further determining the RSRP based on the received power of the LP-SS signal in the first continuous time domain resource.

[0035] In the above embodiment, regardless of whether the received power includes useful signal power, interference signal power and noise signal power are always stably present in the received power. By determining whether the LP-SS signal carries information in the first unit time, whether the received power of the LP-SS signal in the first unit time includes useful signal power, paving the way for subsequently stripping useful signal power from the first power.

[0101] FIG2 is an interactive diagram illustrating a method for determining a measurement metric according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0102] In step 201, the network device 102 determines a reference signal received power (RSRP) according to a low power synchronous LP-SS signal received by the user equipment 101 in continuous time-frequency resources.

[0103] Currently, the measurement metrics used to characterize the signal quality of the measured cell are determined based on the Secondary Synchronization Signal (SSS), as follows:

[0104] RSRP (Reference Signal Received Power) is the power value of the SSS received by the user equipment. The value is the linear average of the power of a single RE (Resource Element) within the measurement bandwidth, reflecting the strength of the useful signal in the cell.

[0105] Reference Signal Received Quality (RSRQ) is the ratio of N times RSRP to RSSI (Received Signal Strength Indication), i.e., RSRQ = N * RSRP / RSSI, where N is the number of REs within the RSSI measurement bandwidth, reflecting the relative size of the useful signal and interference.

[0106] SINR (Signal to Interference & Noise Ratio) is the ratio of useful signal power to the sum of interference and noise power, and directly reflects the quality of the received signal.

[0107] RSSI (Received Signal Strengthen Indicator) is the linear average of the power of all signals received by the user equipment (including useful and interfering signals on the same frequency, adjacent frequency interference, thermal noise, etc.), reflecting the load intensity on the resource.

[0108] With the development of communication technology, a power-saving signal has been introduced for the connected state, namely the Wake-up signal or DCP (DCI for power saving, downlink control information for power saving; DCI is Downlink Control Information, downlink control information); among them, the WUS signal (Wake-up signal) is a low-power detection signal. If the user equipment detects the WUS signal, it is necessary to monitor the PDCCH (physical downlink control channel); if the user equipment does not detect the WUS information, it skips the PDCCH monitoring. Furthermore, a PDCCH skipping mechanism is also introduced for the connected state, that is, PDCCH skipping will be carried in the DCI to notify the user equipment to skip monitoring for a period of time or switch the search space group (Search Space Group, SSG).

[0109] A new power-saving signal, PEI (Paging Early Indicator), has been introduced for idle DRX (Discontinuous Reception) scenarios. PEI is also a low-power detection signal and is typically placed before the Paging Occasion (PO). If the user equipment does not detect PEI, it skips monitoring Paging Downlink Control Information (Paging DCI). If it detects PEI, it monitors Paging DCI.

[0110] In the above technology, no matter what kind of power saving signal it is, the user equipment needs to detect the power saving signal through the main receiver (Main Radio, MR).

[0111] Furthermore, the user equipment may also receive the power saving signal through a low power wake-up receiver (LP-WUR), as follows:

[0112] (1) In idle state, the user equipment monitors the wake-up signal (WUS) sent by the base station through a low-power monitoring module. If the user equipment receives the wake-up signal, the user equipment activates the main communication module to monitor the subsequent Paging Downlink Control Channel (PDCCH). If the user equipment does not receive the wake-up signal, the user equipment does not activate the main communication module.

[0113] (2) After the user equipment receives the low-power wake-up signal in the connected state, it sets the main communication module to a deep / shallow / micro sleep state. At this time, the user equipment only needs to monitor the low-power wake-up signal (LP-WUS). When the low-power wake-up signal is received, the UE controls the main communication module to switch from the sleep state to monitor the Paging PDCCH.

[0114] Among them, in order to obtain sufficient power saving gains, RRM (Radio Resource Management) measurements of at least the serving cell can also be performed on the LP-WUR. Among them, the measurement reference signal used for LP-WUR to perform RRM measurements can multiplex PSS (Primary Synchronization Signal, primary synchronization signal) / SSS / PBCH DMRS (Demodulation Reference Signal of Physical Broadcast Channel; PBCH, i.e. Physical Broadcast Channel, DMRS, i.e. DeModulation Reference Signal, Demodulation Reference Signal), or LP-SS (Low-Power Synchronization Signal, low-power synchronization signal).

[0115] The LP-SS signal is used by the LP-WUR to perform RRM measurements and uses OOK modulation. OOK modulation, also known as on-off keying (OOK), transmits information by adjusting the presence or absence of a carrier signal. When the bit number of the transmitted information is 1 (OOK on), the carrier signal is present; when the bit number of the transmitted information is 0 (OOK off), the carrier signal is off (i.e., no carrier signal exists). To meet measurement requirements, the current measurement metric determination mechanism can be further improved.

[0116] To this end, an embodiment of the present disclosure proposes a method for a network device 102 to determine a reference signal received power RSRP based on a low-power synchronous LP-SS signal received in a continuous time-frequency resource, that is, a method for defining a measurement metric based on an OOK signal is proposed.

[0117] Optionally, in an embodiment of the present disclosure, the received power of the LP-SS signal in the first continuous time domain resource is determined according to whether the LP-SS signal carries information in the first continuous time domain resource;

[0118] The RSRP is determined according to the received power of the LP-SS signal in the first continuous time domain resource.

[0119] Optionally, the LP-SS signal may include at least one bit, and whether the LP-SS signal carries information may be determined by a parameter value of the bit.

[0120] Optionally, the LP-SS signal carries information, that is, the received power of the LP-SS signal includes useful signal power, interference signal power, and noise signal power; the LP-SS signal does not carry information, that is, the received power of the LP-SS signal includes interference signal power and noise signal power.

[0121] As an example, when the parameter value of the bit position is set to "1", it can be set to indicate that the LP-SS signal carries information at the bit position, that is, the received power of the LP-SS signal at the bit position includes the useful signal power, the interference signal power, and the noise signal power; when the parameter value of the bit position is set to "0", it can be set to indicate that the LP-SS signal does not carry information at the bit position, that is, the received power of the LP-SS signal at the bit position includes the interference signal power and the noise signal power.

[0122] Optionally, the RSRP may be determined according to a difference between the power of the LP-SS signal corresponding to the information carrier and the power of the LP-SS signal corresponding to the non-information carrier in the first continuous time domain resource.

[0123] Optionally, when determining the RSRP based on the received power of the LP-SS signal received in the first continuous time domain resource, the received power of the LP-SS signal per unit time can be determined with the unit time of the first continuous time domain resource as the granularity, and the RSRP can be determined based on the average value of the received power of the LP-SS signal per unit time.

[0124] Optionally, in this embodiment of the present disclosure, the first continuous time domain resource includes at least one of the following:

[0125] The duration indicated by a symbol;

[0126] The duration of a time slot indication;

[0131] The first power includes useful signal power and second power, and the second power includes interference signal power and noise signal power.

[0132] Optionally, the first unit time may be a symbol, a time slot, a bit, etc., which is not limited in the embodiment of the present disclosure.

[0133] Optionally, in the embodiment of the present disclosure, determining the RSRP according to the received power of the LP-SS signal received in the first continuous time domain resource includes:

[0134] Determine a first power average value of the LP-SS signal corresponding to a first power in a first continuous time domain resource;

[0155] The RSRP can be obtained by performing conjugate multiplication on the LP-SS signal and the transmitted reference signal at each symbol position, and then adding the conjugate multiplication results of all symbol positions in the second continuous time domain resource.

[0156] Alternatively, the LP-SS signal at each bit position and the transmitted reference signal may be conjugate multiplied in units of bits, and the conjugate multiplication results of all bit positions in the second continuous time domain resource may be added to obtain the RSRP.

[0165] In step 202 , the network device 102 divides the RSRP by the carrier low power synchronization signal strength indicator RSSI (i.e., LP-SS carrier RSSI) of the LP-SS signal to obtain a reference signal received quality RSRQ.

[0166] Optionally, considering that the OOK signal does not have frequency domain information, in the embodiment of the present disclosure, the RSRP can be directly divided by the LP-SS carrier RSSI to obtain the RSRQ, that is, RSRQ=LP-SS-RSRP / LP-SS carrier RSSI.

[0167] In the embodiment of the present disclosure, since there is no concept of the OOK signal frequency domain, when determining RSRQ, there is no need to consider the number of RBs (Resource Blocks), and adaptive modification is made to the RSRQ calculation of the OOK signal.

[0168] In step 202 , the network device 102 divides the RSRP by the second average power value to obtain a signal to interference plus noise ratio (SINR).

[0169] In the embodiment of the present disclosure, the second power average value is the average value of the sum of the interference signal power and the noise signal power.
