wherein the reference signal comprises: TRS or CSI-RS in an idle state or an inactive state.
The idle state or inactive state TRS or CSI-RS may be used for measurement, for example: automatic Gain Control (AGC) measurement, radio Resource Management (RRM), time-frequency synchronization, etc. And the idle state or inactive state TRS or CSI-RS may be configured to the idle state or inactive state TRS or CSI-RS used by the connected terminal, so that a set of dedicated idle state or inactive state TRS or CSI-RS does not need to be configured through a protocol or a network side. Of course, in the embodiments of the present application, this is not limited, for example: in some embodiments, a set of TRS or CSI-RS dedicated for idle state or inactive state may be configured by a protocol or a network side.
Whether the reference signal is available or not may be determined by the terminal based on information acquired by the terminal in advance or content dynamically indicated by the network side.
The first time domain position and the second time domain position may be two different time domain positions, for example: the first time domain position is a time domain position for detecting a power saving signal if the reference signal is available, and the second time domain position is a time domain position for detecting a power saving signal if the reference signal is unavailable.
The above-mentioned detection of the power saving signal may be referred to as listening, receiving, decoding the power saving signal.
In the embodiment of the present application, the power saving signal includes but is not limited to: PEI or WUS.
For example: the first power saving signal includes: a paging advance indication signal PEI or a wakeup signal WUS; and/or
The second power saving signal includes: PEI or WUS.
In the embodiment of the application, the power saving signal is detected according to whether the reference signal can be used, so that the power saving effect of the terminal can be improved. The power saving signal is a power saving signal used for the terminal to determine whether to wake up to monitor the paging message in the subsequent PO, that is, the terminal can determine whether to wake up to monitor the paging message in the subsequent PO according to the detected power saving signal. The paging message may be a paging physical downlink control channel (paging PDCCH).
As an alternative embodiment, the reference signal is not available in case of at least one of:
the terminal receives an availability indication of the reference signal, wherein the availability indication is used for indicating that the reference signal corresponding to the terminal is unavailable;
the terminal does not receive an indication of availability of the reference signal;
an available time of the reference signal has expired;
the cell to which the terminal currently belongs does not support the reference signal;
the terminal does not support the reference signal.
The availability indication is sent to the terminal by the network side equipment, and the availability indication is used for indicating whether the reference signal is available. The availability indication may be indicated by a System information (System information), a paging message, or an RRC release (RRC release message) message.
The indication of availability that the terminal does not receive the reference signal may be an indication of availability that the terminal does not receive or misses the reference signal, for example: the network side device does not send or the network side device has sending but the terminal misses and does not receive.
The expiration of the available time of the reference signal may be that a duration of the available information of the reference signal exceeds a preset time for which the reference signal is available, or that an available preset timer of the reference signal expires.
The terminal not supporting the reference signal may be that the terminal may detect a power saving signal but does not support a TRS or a CSI-RS in an idle state or an inactive state, or the terminal may not detect the power saving signal and does not support the TRS or the CSI-RS in the idle state or the inactive state.
As an alternative embodiment, the reference signal may be available in case of at least one of:
the terminal receives an availability indication of the reference signal, and the availability indication is used for indicating that the reference signal corresponding to the terminal is available;
the time of availability of the reference signal has not expired;
the cell to which the terminal currently belongs supports the reference signal;
the terminal supports the reference signal.
For the above availability indication, reference may be made to the corresponding description of the above embodiments, which is not described herein again.
The time of availability of the reference signal may be that a duration of information of availability of the reference signal does not exceed a preset time of availability of the reference signal, or a preset timer of availability of the reference signal does not expire, or a duration of information of unavailability of the reference signal exceeds a preset time of unavailability of the reference signal, or a preset timer of unavailability of the reference signal expires.
In one embodiment, if the cell to which the terminal currently belongs supports the reference signal, it may be directly determined that the reference signal is available, and in other embodiments, if the cell to which the terminal currently belongs supports the reference signal and the availability indication indicates that the reference signal corresponding to the terminal is available or the available time of the reference signal is not expired, it may be determined that the reference signal is available.
The terminal may support the reference signal, and the terminal may detect the power saving signal and support the reference signal. In one embodiment, if the terminal supports the reference signal, it may directly determine that the reference signal is available, and in other embodiments, if the terminal supports the reference signal and the availability indication indicates that the reference signal corresponding to the terminal is available or the available time of the reference signal is not expired, it may determine that the reference signal is available.
In some embodiments, whether the terminal supports the reference signal or not, or whether the cell supports the reference signal may not be considered, for example: the terminal may be defaulted to support reference signals and the cell may be defaulted to support reference signals.
As an optional implementation, at least one of the first time domain position and the second time domain position is determined according to at least one of the following:
configuration information of a power saving signal received by the terminal;

Of course, when only one set of configuration information is configured, the first time domain position and the second time domain position are both time domain positions determined by the configuration information, that is, when the reference signal is available or unavailable, the power saving signal is detected according to the time domain positions determined by the configuration information.

The duration is a duration for the terminal to detect the power saving signal, and may specifically be a duration for each time domain position detection, and the durations of different time domain position detections may be the same or different.
The PO information may include at least one of:
the number of POs corresponding to the power saving signal, and the index of the POs corresponding to the power saving signal.
In addition, the configuration information may be indicated by a system message, an RRC release message, or the like.
It should be noted that one or more of the time domain resource information, the frequency domain resource information, the duration and the PO information may be configured in advance for the terminal, or a protocol is defined in advance.
The capability information of the terminal may be capability information reported by the terminal to the network side, or capability information pre-stored by the terminal. The capability information may be used to determine at least one of the first time domain location and the second time domain location, for example: the capability information includes related information for deriving at least one of the first time domain position and the second time domain position.
Optionally, the capability information of the terminal includes:
time domain resource information.
The time domain resource information is associated with at least one of the first time domain position and the second time domain position, and at least one of the first time domain position and the second time domain position can be determined by the time domain resource information. And the time domain resource information included in the capability information may be time domain resource information desired by the terminal.
Since at least one of the first time domain position and the second time domain position can be determined by the capability information, transmission overhead can be saved.
The PO location may be a preconfigured PO location, and the PO location may determine at least one of the first time domain location and the second time domain location by combining at least one of the capability information and the configuration information, or determine at least one of the first time domain location and the second time domain location only according to the PO location, for example: a mapping relationship between the PO position and at least one of the first time domain position and the second time domain position is defined in advance.
It should be noted that, in the embodiment of the present application, a determination manner of determining at least one of the first time domain location and the second time domain location according to at least one of the configuration information, the capability information, and the PO location is not limited, for example: these determinations may be pre-configured and/or agreed upon.
Optionally, in the foregoing embodiment, the time domain resource information includes at least one of:
first time domain resource information and second time domain resource information.
The first time domain resource information may be time domain resource information for determining a detection position of a power saving signal if the reference signal is available, and the second time domain resource information may be time domain resource information for determining a detection position of a power saving signal if the reference signal is unavailable.
The first time domain resource information may be used to determine the first time domain position, and the second time domain resource information may be used to determine the second time domain position.
In this embodiment, when the reference signal is available, determining the first time domain position by using the first time domain resource information or determining the second time domain position by using the second time domain resource information, and detecting the power saving signal may be implemented, and when the reference signal is unavailable, determining the second time domain position by using the second time domain resource information, and detecting the power saving signal may be implemented.
Optionally, the first time domain resource information is used to indicate a first offset value between a time domain position of the first power saving signal and a first PO, and the second time domain resource information is used to indicate a second offset value between a time domain position of the second power saving signal and a second PO;

The terminal detects the first power saving signal at a first time domain location if the first offset value is less than the second offset value and the reference signal is available.
The first PO and the second PO may be the same PO or different POs.
The first offset value may be an offset value between a time domain start position of the detection timing of the first power saving signal and a time domain start position of the first PO, or the first offset value may be an offset value between a time domain end position of the detection timing of the first power saving signal and a time domain start position of the first PO. The second offset value can refer to the description of the first offset value, and is not described herein. The first offset value and the second offset value may be two different offset values.
In addition, the specific content of the first time domain resource information and the second time domain resource information is agreed by a protocol, and the unit thereof may be one of a frame, a subframe, a timeslot, a second, and a millisecond.
In this embodiment, the power saving signal can be detected in the time domain closer to the PO in the case that the reference signal is available, so that the power consumption of the terminal can be further saved.
Optionally, when the first power saving signal corresponds to one PO, the first PO is a PO corresponding to the first power saving signal, and when the second power saving signal corresponds to one PO, the second PO is a PO corresponding to the second power saving signal; or

The first power saving signal corresponds to one PO, which means that one first power saving signal corresponds to one PO, in this case, the first PO may monitor the paging PDCCH for the terminal. The second power saving signal corresponds to one PO, which means that one second power saving signal corresponds to one PO, and in this case, the second PO may be an opportunity for the terminal to monitor the paging PDCCH.
The first power saving signal corresponds to a plurality of POs, where the first predetermined PO may be a first PO, a last PO, or any PO in the plurality of POs corresponding to the first power saving signal, and may specifically be agreed by a protocol. Here, the first PO is the PO with the closest time position from the power saving signal, and the last PO is the PO with the farthest time position from the power saving signal.

In a case that a plurality of power saving signals correspond to a PO, the time domain position of the first preset power saving signal may be a first power saving signal or a last power saving signal or any one power saving signal corresponding to the PO; the time domain position of the second preset power saving signal may be a first power saving signal or a last power saving signal or any one power saving signal corresponding to the PO, which may be specified by a protocol. The first power saving signal is the power saving signal with the closest time position to the PO, and the last power saving signal is the power saving signal with the farthest time position to the PO.
As an alternative embodiment, in the case that the reference signal is available and the power saving signal is detected at the first time domain position, the time domain distance from the PO of the first time domain position is smaller than the time domain distance from the PO of the second time domain position.
In this embodiment, it is possible to detect the power-saving signal at the time domain position closer to the PO in the case where the reference signal is available, which can save the power consumption of the terminal because the terminal can perform operations such as detection, synchronization, and the like using the reference signal in this case, thereby not needing to wake up too early.
In addition, a power-save Signal is detected at a time-domain location farther from the PO if the reference Signal is unavailable, the terminal may then synchronize using a Synchronization Signal Block (SSB) prior to receiving the page. And the time domain distance of the second time domain position from the PO can also ensure the correct decoding of the paging for the sparse SSB.
In the following, the reference signal is TRS/CSI-RS, and the power saving signal is PEI, for example:
in the case that TRS/CSI-RS is not available, the following may be included:
step 1, a terminal receives configuration information of a PEI opportunity (PEI interference) broadcasted by a network side, wherein the configuration information comprises time domain resource information of PEI interference, and specifically PEI offset value (PEI-offset) 1 and/or PEI-offset2; the agreement provides that PEI-offset1 and/or PEI-offset2 is the separation of the PEI's starting location from the starting location of its corresponding PO.
And 2, if the terminal does not receive any indication about whether the TRS/CSI-RS is available, the terminal deduces the initial position of the PEI occasting 1 according to the PEI-offset1 obtained in the step 1, the specific time domain position of the PO and the time domain resource information of the current cell, obtains the duration of the PEI occasting 1 through the duration in the PEI occasting 1 configuration information, and the UE wakes up at the time domain position to monitor the PEI. Specifically, as shown in fig. 3, in the case that the TRS is unavailable, the terminal wakes up from deep sleep to detect PEI at PEI occase 1, and then detects one or more SSBs, where multiple SSBs may be detected for a low Signal to Interference plus Noise Ratio (SINR) scenario, and only one SSB may be detected for a high SINR scenario. Then, the paging message is received again at the PO. Here, the SSB detected here may be an SSB burst set (SSB burst set), where a set formed by all SSBs in one beam scan is referred to as an SS burst set.
Another example, includes the steps of:
step 1, a terminal receives configuration information of PEI (polyetherimide) interference broadcast by a network side, wherein the configuration information comprises time domain resource information PEI-offset1 and/or PEI-offset2 of PEI interference; the protocol convention is that PEI-offset1 and/or PEI-offset2 is the interval between the initial position of PEI and the initial position of PO corresponding to the PEI;
step 2, if the terminal receives the available availability indication of the TRS/CSI-RS through the paging message or the PEI or the system information or the RRC release, the terminal judges the sizes of the PEI-offset1 and the PEI-offset2 obtained in the step 1, if the PEI-offset2 is smaller than the PEI-offset1, according to the PEI-offset2 obtained in the step 1, deducing the initial position of the PEI occasion2 from the specific time domain position of the PO and the time domain resource information of the current cell, obtaining the duration of the PEI occasion2 according to the duration in the PEI occasion configuration information, enabling the terminal to wake up at the time domain position to monitor the PEI, enabling the terminal not to wake up at the PEI occasion1 correspondingly, and otherwise, still waking up at the PEI occasion1 obtained in the step 2 to monitor the PEI. For example: as shown in fig. 4, in the case that the TRS is available, the terminal wakes up at PEI event 1 or is in deep sleep, wakes up at PEI event 2 from deep sleep to detect PEI, and detects the TRS, and may also detect SSB in a low SINR scenario, or may not detect SSB in a high SINR scenario.
And step 3, if the terminal receives an unavailable availability indication of the TRS/CSI-RS through a paging message or PEI or system information or RRC release, and/or the duration of the available information of the TRS/CSI-RS exceeds the available preset time of the TRS or the available preset timer of the TRS/CSI-RS expires, the terminal wakes up in PEI occase 1 to monitor the PEI.

Therefore, the terminal can detect the PEI or the wake-up signal WUS according to whether the reference signal is available or not, and the power saving effect of the terminal is improved.
