In addition, the specific content of the above-mentioned first time domain resource information and the second time domain resource information is agreed by the protocol, and the unit may be one of frame, subframe, time slot, second, and millisecond.

In this embodiment, when the reference signal is available, the power saving signal can be detected in the time domain closer to the PO, thereby further saving the power consumption of the terminal.

Optionally, in the case that the first power saving signal corresponds to one PO, the first PO is the PO corresponding to the first power saving signal, and in the case that the second power saving signal corresponds to one PO , the second PO is the PO corresponding to the second power-saving signal; or

When the first power saving signal corresponds to a plurality of POs, the first PO is a first preset PO of the plurality of POs corresponding to the first power saving signal, and the second power saving signal corresponds to a first preset PO of the POs. In the case of multiple POs, the second PO is the second preset PO of the multiple POs corresponding to the second power saving signal; or

In the case where multiple power-saving signals correspond to one PO, the first time-domain position is a time-domain position of a first preset power-saving signal among the plurality of power-saving signals, and the second time-domain position is the time domain position of the second preset power saving signal among the plurality of power saving signals.

The above-mentioned first power-saving signal corresponds to one PO means that one first power-saving signal corresponds to one PO. In this case, the above-mentioned first PO may be an opportunity for the terminal to monitor and paging the PDCCH. The above-mentioned second power-saving signal corresponds to one PO means that one second power-saving signal corresponds to one PO. In this case, the above-mentioned second PO may be an opportunity for the terminal to monitor and paging the PDCCH.

The above-mentioned first power-saving signal corresponding to multiple POs means that one first power-saving signal corresponds to multiple POs. In this case, the above-mentioned first preset PO may be the first one of the multiple POs corresponding to the first power-saving signal PO or the last PO or any PO, which can be specified by agreement. The first PO here is the PO whose time position is closest to the power saving signal, and the last PO is the PO whose time position is the farthest from the power saving signal. The above-mentioned second power-saving signal corresponding to multiple POs means that one second power-saving signal corresponds to multiple POs. In this case, the above-mentioned second preset PO may be the first one of the plurality of POs corresponding to the second power-saving signal PO or the last PO or any PO, which can be specified by agreement.

In the case where multiple power-saving signals correspond to one PO, the time domain position of the first preset power-saving signal may be the first power-saving signal or the last power-saving signal or any power-saving signal corresponding to the PO ; The time domain position of the second preset power-saving signal may be the first power-saving signal or the last power-saving signal or any power-saving signal corresponding to the PO, which may be specified in an agreement. The first power-saving signal here is the power-saving signal whose time position is closest to PO, and the last power-saving signal is the power saving signal whose time position is farthest from PO.

As an optional implementation manner, when the reference signal is available and the power-saving signal is detected at the first time-domain position, the time-domain distance from the first time-domain position to the PO is smaller than the second time-domain position The time domain distance from the PO.

In this embodiment, when the reference signal is available, the power-saving signal can be detected at a time domain position close to the PO, which can save the power consumption of the terminal, because in this case, the terminal can use the reference signal for detection and synchronization. wait for the operation so that there is no need to wake up too early.

In addition, when the reference signal is unavailable, the power saving signal is detected at a time domain position far away from the PO, so that the terminal can use a synchronization signal block (Synchronization Signal block, SSB) for synchronization before receiving the paging. In addition, the time domain distance of the second time domain position from the PO can also ensure that the paging is correctly decoded even for sparse SSBs.

The following example takes the reference signal as TRS/CSI-RS and the power saving signal as PEI:

In the case where TRS/CSI-RS is not available, the following can be included:

Step 1, the terminal receives the configuration information of the PEI occasion (PEI occasion) broadcasted by the network side, which includes the time domain resource information of a PEI occasion, specifically the PEI offset value (PEI-offset) 1 and/or PEI-offset 2; Protocol It is agreed that PEI-offset1 and/or PEI-offset2 are the interval between the starting position of PEI and the starting position of the corresponding PO.

Step 2, the terminal does not receive any indication about whether TRS/CSI-RS is available, then the terminal deduces the start of PEI occurrence1 according to the PEI-offset1 obtained in step 1, the specific time domain position of PO and the time domain resource information of the current cell. Start position, and obtain the duration of PEI occasion1 through the duration in the PEI occasion1 configuration information, the UE wakes up at this time domain position to monitor the PEI. Specifically, as shown in Figure 3, in the case where TRS is unavailable, the terminal wakes up from deep sleep at PEI occasion1 to detect PEI, and then performs one or more SSBs. Interference plus Noise Ratio, SINR) scenarios can detect multiple SSBs, and for high SINR scenarios, only one SSB can be detected. Afterwards, the paging message is received at the PO. Among them, the SSB detected here can be an SSB burst set (SSB burst set), and the set of all SSBs in a beam scan is called SS burst set. Further, after PO, it is also possible to detect inter-frequency SSB bursts set (SSB burst for interFreaquency).

Another example includes the following steps:

Step 1. The terminal receives the configuration information of the PEI occasion broadcast by the network side, which includes the time domain resource information PEI-offset1 and/or PEI-offset2 of a PEI occasion; The interval between the starting position and the starting position of the corresponding PO;

Step 2. If the terminal receives the availability indication that TRS/CSI-RS is available through paging message or PEI or system information or RRC release, the terminal judges the size of PEI-offset1 and PEI-offset2 obtained in step 1, if PEI-offset2 Compared with PEI-offset1, which is smaller, according to PEI-offset2 obtained in step 1, the specific time domain position of PO and the time domain resource information of the current cell, the starting position of PEI occasion2 is deduced, and the starting position of PEI occasion2 is deduced through the PEI occasion configuration information. The duration is obtained from the duration of PEI occasion2. The terminal wakes up at the time domain position to monitor the PEI. Correspondingly, the terminal will not wake up in PEI occasion1, otherwise it will still wake up to monitor the PEI at the PEI occasion1 obtained in step 2. For example, as shown in Figure 4, when TRS is available, the terminal does not wake up at PEI occasion1 or is in deep sleep, wakes up from deep sleep at PEI opportunity 2 to detect PEI, and detects TRS, which is also possible in low SINR scenarios Detect SSB, or not detect SSB in high SINR scenarios.

Step 3. If the terminal receives the availability indication that TRS/CSI-RS is unavailable through paging message or PEI or system information or RRC release, and/or the duration of TRS/CSI-RS available information exceeds the preset time that TRS is available Or the TRS/CSI-RS available preset timer expires, and the terminal wakes up at PEI occasion1 to monitor the PEI.
