Fig. 1 illustrates a network architecture to which embodiments of the present application may be applied. As shown in fig. 1, the network architecture provided by the present embodiment includes: network device 101 and terminal device 102. The terminal devices related to the embodiments of the present application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other electronic devices connected to a wireless modem, and various forms of user terminal devices (terminal devices) or Mobile Stations (MSs), etc. with wireless communication functions. The network device according to the embodiment of the present application is a device deployed in a radio access network to provide a terminal device with a wireless communication function. In the embodiment of the present application, the network device may be, for example, a base station shown in fig. 1, and the base station may include various forms of electronic devices such as a macro base station, a micro base station, a relay station, and an access point.

Fig. 2 shows a service scenario to which the method for selecting an SSB and windowing (windowing) the SSB to receive the selected SSB may be applied, and the method provided in the embodiment of the present application may be applied to a Discontinuous Reception (DRX) mechanism of a terminal device. Specifically, the method provided by the embodiment of the present application may be applied to an idle DRX mechanism and a connected DRX mechanism.

Wherein, the idle state DRX mechanism is the paging mechanism. Fig. 2 shows a DRX cycle, in which a terminal device in an idle state monitors a Physical Downlink Control Channel (PDCCH) only for a specific time period (i.e., a paging monitoring occasion) to receive a paging message. And the monitoring function can be turned off at other times without monitoring the PDCCH.

In addition, in the connected DRX mechanism, the terminal device may monitor the PDCCH for a specific time period (i.e., a continuous monitoring opportunity) to receive information transmitted by the network device. The PDCCH is not monitored at other times (i.e., non-monitoring occasions).

In some embodiments, the paging listening opportunity and the continuous listening opportunity may be configured by the network device or predefined, which is not limited in this embodiment of the present application.

In general, the terminal device may determine different operating modes (e.g., deep sleep mode, light sleep mode, active mode, etc.) according to different application scenarios, for example, the terminal device may be in the active mode at a time domain position of a paging monitoring occasion to monitor the PDCCH, and be in the deep sleep mode at other time domain positions to turn off a monitoring function. Different operating modes have different requirements on the processing capacity of the terminal device. The terminal device can adjust the operating Frequency and Voltage of the chip by a Dynamic Voltage and Frequency Scaling (DVFS) technology according to the determined working mode to meet the requirements of different working modes.

In practical applications, the terminal device needs to perform pre-synchronization with the network device before the paging monitoring opportunity or the continuous monitoring opportunity, and the terminal device also needs to perform neighbor measurement after the pre-synchronization. Therefore, the terminal device also needs to window the SSB for pre-synchronization to receive the SSB for pre-synchronization before paging the listening occasion or continuing the listening occasion, so as to complete pre-synchronization with the network device. In addition, after the pre-synchronization is completed, the terminal device may further perform windowing on the SSB for neighbor cell measurement to receive the SSB for neighbor cell measurement, thereby implementing neighbor cell measurement.

Referring to fig. 3, a flow chart of a method for selecting and receiving an SSB in the related art is shown. Specifically, after entering the 5G standby mode, the terminal device may first determine a time domain location of at least one of a Paging Frame (PF), a Paging location (PO), and a Monitoring location (MO). Here, the terminal device may determine the time domain position of the PF/PO according to the network configuration and the identification Information (ID) of the terminal device, or calculate the time domain position of the MO according to the beam in which the terminal device is currently located.

Further, the terminal device may statically determine one or more SSBs for pre-synchronization (hereinafter referred to as SSBs for pre-synchronization) according to the time domain location of the PO/PF/MO. Specifically, the terminal device may perform operations such as Automatic Gain Control (AGC) or Automatic Frequency Control (AFC) according to the SSB for pre-synchronization. In addition, when the neighbor cell measurement is required, the terminal device may further statically select an SSB for neighbor cell measurement (hereinafter referred to as an SSB for neighbor cell measurement) according to the period of the neighbor cell measurement, so as to implement the neighbor cell measurement operation of the terminal device.

After the SSBs for pre-synchronization and the SSBs for neighbor measurement are determined, the terminal device may determine the operating modes of the terminal device at different time domain positions according to the position relationship between the time domain position of the PF/PO/MO and the time domain position of the SSBs (including the SSBs for pre-synchronization and/or the SSBs for neighbor measurement). Furthermore, the terminal device may receive a paging message according to the determined working mode, or perform neighbor cell measurement.

For example, in a scenario where the terminal device does not need to perform neighbor measurement, referring to a windowing power consumption timing diagram of the terminal device in the prior art shown in fig. 4A, the terminal device may use two SSBs located before the PF as SSBs for pre-synchronization.

Wherein the terminal device may wake up from the deep sleep mode before the time domain position of the first SSB for pre-synchronization arrives, may be in the active mode when the first SSB for pre-synchronization (SSB 1 in the figure) arrives, and may receive the first SSB for pre-synchronization (SSB 2 in the figure) in the active mode. Since the two SSBs for pre-synchronization (SSB 1, SSB2 in the figure) in fig. 4A are located close to each other in the time domain, the terminal device can enter the doze mode immediately after receiving the first SSB for pre-synchronization (SSB 1 in the figure). It can be understood that, in the light sleep mode, the terminal device can adjust the frequency and pressure of the chip to turn off part of the monitoring function, so as to save the power consumption of the terminal device. When the starting time of the time domain position of the second SSB for pre-synchronization (SSB 2 in the figure) arrives, the terminal device can immediately enter the active mode from the doze mode, in which it receives the second SSB for pre-synchronization. After the terminal device receives the second SSB for pre-synchronization, the terminal device may enter the doze mode again to reduce power consumption. When the time domain position of the PF arrives, the terminal device may enter the active mode again from the light sleep mode to monitor the paging message, and after the PO in the PF is ended, the terminal device enters the deep sleep mode until the SSB for pre-synchronization corresponding to the next DRX cycle arrives. In the deep sleep mode, the terminal equipment closes the monitoring function, and the power consumption is lowest.

For example, in a scenario in which the terminal device needs to perform the neighbor cell measurement, referring to a power consumption timing diagram of the terminal device in another related art shown in fig. 4B, after the terminal device selects an SSB for pre-synchronization (SSB 1 'in the drawing), a first SSB (SSB 2' in the drawing) located after the SSB for pre-synchronization may be used as an SSB for neighbor cell measurement.

The terminal device may wake up from the deep sleep mode before the time domain position of the SSB for pre-synchronization arrives, may be in the active mode when the SSB for pre-synchronization (SSB 1 'in the figure) arrives, and may receive the SSB for pre-synchronization (SSB 1' in the figure) in the active mode and perform synchronization processing. In addition, the time domain positions of the pre-synchronization SSB and the MO in the PF are close to each other, and the terminal equipment can immediately enter a light sleep mode after receiving the pre-synchronization SSB in the activation mode, so that the power consumption is saved, and meanwhile, the terminal equipment can conveniently and quickly enter the activation mode when the PF arrives. Before the PF arrives, the terminal device may enter the active mode from the doze mode to listen for paging messages. Since the time domain positions of the PF and the SSB for neighbor measurement (SSB 2 'in the figure) are closer to each other, the terminal device is not in time to switch the operation mode, and therefore, the terminal device continues to be in the active mode after the PF and continues to monitor the downlink channel until receiving the SSB for neighbor measurement (SSB 2' in the figure). After receiving the SSB for neighbor measurement, the terminal device may immediately enter the deep sleep mode until the SSB for pre-synchronization corresponding to the next DRX cycle arrives.

As can be seen from the above example, in the related art, the terminal device determines the SSBs (including the SSBs for pre-synchronization and the SSBs for neighbor cell measurement) in a static manner, and further, the terminal device divides different operating modes for the terminal device according to a position relationship between a time domain position of the SSBs and a reference time domain position. However, in the power consumption control method in the related art, dividing the operating modes of the terminal device in different time domain positions according to the statically determined SSB may limit the division of the operating modes of the terminal device, resulting in a single mode division manner, and in addition, the scheme of statically selecting the SSB does not consider the power consumption factor of windowing the SSB.

Based on this, the embodiment of the present application provides a receiving method of an SSB, which may be applied to the terminal device shown in fig. 1. Specifically, the terminal device may determine at least two SSBs; respectively determining the power consumption corresponding to each SSB in a preset time period based on the windowing power consumption time sequence corresponding to each SSB; the windowing power consumption time sequence represents the power consumption required by the terminal equipment for windowing at different time domain positions in the preset time period; and selecting the SSB with the power consumption meeting the preset condition from the at least two SSBs to obtain a target SSB candidate set. The terminal device can also dynamically select a better SSB from the plurality of SSBs to perform presynchronization or neighbor measurement by calculating and comparing the power consumption corresponding to the plurality of SSBs, so that the power consumption of the terminal device is reduced, and the standby time of the terminal device is prolonged.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

An embodiment of the present application provides an SSB receiving method, fig. 5 is a first flowchart of the SSB receiving method provided in the embodiment of the present application, and referring to fig. 5, in the embodiment of the present application, the SSB receiving method may include the following steps 110 to 130:

step 110, determining at least two SSB candidate sets, where the SSB candidate set includes at least one SSB, and the embodiment of the present application does not limit the number of SSBs included in the SSB candidate set, and those skilled in the art can select a specific number of SSBs according to actual needs.

For example, referring to fig. 6A, the terminal device may select SSB1 and SSB2 as the first SSB candidate set and SSB3 as the second SSB candidate set from SSB1, SSB2, and SSB 3. The terminal device may also select SSB1 as the first SSB candidate set, SSB2 as the second SSB candidate set, and SSB3 as the third SSB candidate set from among SSB1, SSB2, and SSB 3.

The terminal device may further select one or more SSBs from the plurality of SSBs based on a certain rule, so as to obtain the at least two SSB candidate sets. The manner in which the at least two SSBs are determined is not limited in this application.

In some embodiments, the SSB may be a SSB for pre-synchronization, where the SSB for pre-synchronization is used to implement pre-synchronization between the terminal device and the network device; the SSB may also be an SSB for neighbor measurement; the SSB for measuring the adjacent region is used for realizing the adjacent region measurement of the terminal equipment. The application of the SSB is not limited in the embodiments of the present application.

And step 120, respectively determining the power consumption corresponding to each SSB candidate set in a preset time period based on the windowing power consumption sequence corresponding to each SSB.

The windowing power consumption time sequence represents the power consumption of the terminal equipment for windowing at different time domain positions in a preset time period.

In some embodiments, after determining the plurality of SSB candidate sets, different operating modes may be partitioned for the terminal device according to time domain locations of the SSB candidate sets.

For example, referring to fig. 6A, the terminal device may divide the operation mode according to the relationship between the time domain position of each SSB and the time domain position of the PF/PO/MO. In the case where SSB1 is determined to be the first SSB candidate set, the terminal device may determine to be in a deep sleep mode before the time domain position of SSB1, and at some time before the time domain position start time of SSB1 arrives, the terminal device may wake up from the deep sleep mode and enter an active mode at the time domain position of SSB1 to receive SSB 1. Further, since the time interval between the temporal location of the SSB1 and the temporal location of the PF is small, the terminal device continues to be in the active mode after the pre-synchronization is completed until the PF/PO/MO ends. And the terminal equipment enters a deep sleep mode after the MO is finished.

In the embodiment of the application, because different working modes have different requirements on the processing capacity of the terminal device, the power consumption of the terminal device in different working modes is different. Illustratively, when the terminal device is in the active mode, the terminal device may continuously listen to the signal sent by the network device, and perform corresponding processing based on the signal. And when the terminal equipment is in the deep sleep mode, the monitoring function can be closed, and the signal sent by the network equipment is not monitored. Obviously, the power consumption of the terminal device in the active mode is greater than the power consumption in the deep sleep mode.

Based on this, the terminal device may determine the power consumption time sequence within the preset time period, that is, the power consumption of the terminal device at different time domain positions within the preset time period, according to the divided working modes.

For example, referring to fig. 6A, when SSB1 is used as the first SSB candidate set for presynchronization, the power consumption timing sequence corresponding to SSB1 can be shown by referring to curve 61 in fig. 6A; when the SSB2 is used as the second SSB candidate set for presynchronization, the power consumption timing sequence corresponding to the SSB2 can be referred to as curve 62 in fig. 6A; when the SSB3 is used as the third SSB candidate set for pre-synchronization, the power consumption timing sequence corresponding to the SSB3 may be shown by referring to a curve 63 in fig. 6A, that is, in this embodiment, the SSB candidate set only includes one SSB, the application is not limited thereto, and the SSBs included in the SSB candidate set may be set according to actual requirements, which is well known to those skilled in the art.

In some embodiments, the terminal device may calculate the power consumption amount of the terminal device for windowing each SSB candidate set based on the corresponding windowing power consumption timing sequence of the SSB candidate set. The preset time period may be one data transmission cycle or two data transmission cycles, which is not limited in the embodiment of the present application. The data transmission cycle may be a paging cycle or a DRX cycle.

In addition, the power consumption may be a total windowing power consumption in a preset time period, or may be an average power consumption in the preset time period, which is not limited in the embodiment of the present application.

For example, in fig. 6A, the terminal device may calculate the integration results of the curve 61, the curve 62, and the curve 63, respectively, to obtain the power consumption amounts corresponding to the SSB1, the SSB2, and the SSB3, respectively.

Step 130, determining an SSB candidate set with power consumption meeting a preset condition from at least two SSB candidate sets to obtain a target SSB candidate set. In the present invention, three SSB candidate sets are provided, and other numbers of SSB candidate sets are also possible.

In the embodiment of the application, after the power consumption corresponding to each SSB candidate set is obtained through calculation, the terminal device may select, according to the power consumption corresponding to each SSB candidate set, an SSB candidate set whose power consumption meets a preset condition from the plurality of SSB candidate sets, so as to obtain a target SSB candidate set.

In some embodiments, the preset condition comprises any one of:

1, selecting an SSB candidate set with the windowing power consumption not being the maximum value from at least two SSB candidate sets as a target SSB candidate set; and the number of the first and second groups,

and 2, selecting an SSB candidate set with windowing power consumption smaller than a preset power consumption threshold from the at least two SSB candidate sets as a target SSB candidate set.

For 1, the SSB candidate set with the smaller one of the windowing power consumptions of the first SSB candidate set and the second SSB candidate set is selected as the target SSB candidate set, for example, as shown in FIG. 6A, it is assumed that SSBs 1-3 in FIG. 6A are SSB candidate sets including one SSB, and the corresponding windowing power consumptions are related as follows: SSB2 (windowing power consumption minimum) < SSB1 < SSB3 (windowing power consumption maximum). In one possible implementation, SSB1 may be selected because SSB1 (equivalent to the first SSB candidate set) < SSB3 (equivalent to the second SSB candidate set); in yet another possible implementation, SSB2 may be selected due to SSB2 (equivalent to the first SSB candidate set) < SSB1 (equivalent to the second SSB candidate set), which may also be understood due to SSB2 (equivalent to the first SSB candidate set) < SSB3 (equivalent to the second SSB candidate set). Therefore, the SSB candidate set is dynamically selected for receiving according to the windowing power consumption of the SSB, so that the SSB candidate set with the largest windowing power consumption is excluded, and the effect of saving power consumption is achieved.

In one possible implementation, the SSB candidate set with the lowest windowing power consumption may be selected as the target SSB candidate set. For example, in the above example, since the windowing power consumption of the SSB2 is the smallest, the SSB candidate set with the smallest windowing power consumption may be selected as the target SSB candidate set. In this case, SSB2 may be understood as the first SSB candidate set, and SSB1 and SSB3 may both be understood as the second SSB candidate set. This further improves the effect of saving power consumption.

For 2, selecting an SSB candidate set with a windowing power consumption amount smaller than a preset power consumption threshold from the at least two SSB candidate sets as a target SSB candidate set. For example, as shown in fig. 6A, it is assumed that SSBs 1-3 in fig. 6A are SSB candidate sets respectively including one SSB, and the relationship between the corresponding windowing power consumption and the preset power consumption threshold a is: SSB2 (windowing power consumption minimum) < SSB1 < a < SSB3 (windowing power consumption maximum). In one possible implementation, SSB1 may be selected because SSB1 < a; in yet another possible implementation, SSB2 may be selected because SSB2 < a. Therefore, the SSB candidate set with the power consumption smaller than the preset power consumption threshold is selected as the target SSB candidate set. Therefore, the double technical effects of calculating complexity and saving power consumption are considered.

In some embodiments, after determining the target SSB candidate set, the terminal device may further perform the following steps:

and receiving the SSBs in the target SSB candidate set, and performing pre-synchronization processing or neighbor cell measurement processing based on the SSBs in the target SSB candidate set.

It is understood that the terminal device, after determining the target SSB candidate set, may perform power consumption control based on the target SSB candidate set. That is, the terminal device may receive the SSBs in the target SSB candidate set based on the operation mode of the target SSB candidate set division, and perform pre-synchronization based on the received SSBs to receive the paging message, or perform neighbor cell measurement based on the SSBs. Specifically, if the target SSB candidate set is the SSB for pre-synchronization, the terminal device may perform pre-synchronization processing according to the SSB after receiving the SSB in the target SSB candidate set, and receive the paging message. If the target SSB is an SSB for neighbor measurement, the terminal device may perform neighbor measurement processing according to the SSB after receiving the SSB in the target SSB candidate set.

It should be noted that the terminal device may adjust the operating frequency and voltage of the terminal device through the DVFS technology, so that the terminal device is in different operating modes.

It can be understood that in the receiving method of the SSB provided in the embodiment of the present application, the terminal device may calculate and compare the power consumption amount corresponding to each SSB candidate set, and dynamically select a target SSB candidate set with a smaller power consumption amount from at least two SSB candidate sets, so as to perform power consumption control based on the target SSB candidate set, thereby reducing the power consumption of the terminal device and prolonging the standby time of the terminal device.

Based on the foregoing embodiment, referring to fig. 7, in an embodiment of the present application, the determining at least two SSB candidate sets in step 110 may be implemented by:

step 1101, acquiring a plurality of selection conditions;

step 1102, determining, from the plurality of SSB candidate sets, an SSB candidate set that satisfies each selection condition of the plurality of selection conditions, to obtain at least two SSB candidate sets.

It can be understood that, according to a certain selection rule, the terminal device in the embodiment of the present application may determine the at least two SSB candidate sets from the multiple SSB candidate sets.

In some embodiments, the terminal device may obtain a plurality of selection conditions in advance, determine, from the plurality of SSB candidate sets, an SSB candidate set that satisfies each selection condition, and obtain the at least two SSB candidate sets.

Illustratively, when two SSB candidate sets need to be determined, the terminal device may determine two selection conditions. In this way, the terminal device may determine, from the plurality of SSB candidate sets, an SSB candidate set that satisfies the first selection condition to obtain an SSB candidate set, and further determine, from the plurality of SSB candidate sets, an SSB candidate set that satisfies the second selection condition to obtain a second SSB candidate set, so as to obtain two SSB candidate sets. For example, the terminal device may select, from the plurality of SSB candidate sets, an SSB candidate set in which a time interval between the time domain position and the reference time domain position is less than 3 milliseconds, to obtain an SSB candidate set; and selecting an SSB candidate set with a time interval between the time domain position and the reference time domain position larger than 3 milliseconds from the plurality of SSB candidate sets to obtain another SSB candidate set.

In some embodiments, the plurality of selection conditions are conditions that need to be satisfied by a time interval between a temporal location of the SSB candidate set and a reference temporal location.

Here, the reference time domain location may include a time domain location of the target listening opportunity, and/or a time domain location of the first SSB. The target listening opportunity may comprise a paging listening opportunity in a DRX mechanism, and/or a continuous listening opportunity. The first SSB refers to an SSB determined by the terminal device for pre-synchronization. The paging listening occasion here may include at least one of PF, PO, or MO.

In some embodiments, in the case that the SSB candidate set is a presynchronization-use SSB candidate set, the reference time domain position is a time domain position of the target listening opportunity; and under the condition that the SSB candidate set is used for measuring the adjacent regions, the reference time domain position is the time domain position of the first SSB.

Specifically, the terminal device may acquire a plurality of selection conditions. The plurality of selection conditions are conditions that a time interval between the time domain position of the SSB and the reference time domain position needs to be satisfied. For example, the selection condition may be that the time interval is greater than a certain threshold, or less than a certain threshold.

For example, in a scenario where the SSB candidate set is a presynchronization SSB candidate set, the first selection condition may be that an interval between a time domain position of the SSB candidate set and a time domain position of the target listening opportunity is less than 3 milliseconds, and the second selection condition may be that an interval between a time domain position of the SSB candidate set and a time domain position of the target listening opportunity is greater than or equal to 3 milliseconds. Referring to FIG. 6A, the temporal location between the temporal location of SSB1 and the PO is less than 3 milliseconds, and the temporal location between the temporal location of SSB2 and the PO is greater than 3 milliseconds. The terminal device selects SSB1, the first SSB candidate set, and SSB2 as the second SSB candidate set.

In a scenario where the SSB candidate set is an SSB candidate set for neighbor measurement, the first selection condition may be that an interval between a time domain position of the first SSB candidate set and a time domain position of the SSB candidate set is less than 3 milliseconds, and the second selection condition may be that an interval between a time domain position of the second SSB candidate set and a time domain position of the SSB candidate set is greater than or equal to 3 milliseconds. Referring to FIG. 6B, the temporal location between the temporal location of SSB4 and the PO is less than 3 milliseconds, and the temporal location between the temporal location of SSB5 and the PO is greater than 3 milliseconds. The terminal device may select SSB4, the first SSB candidate set, and SSB5 as the second SSB candidate set.

That is, the SSB candidate set determined by the selection condition (i.e., the time interval between the time domain position of the SSB candidate set and the reference time domain position) has a time interval different from the time interval between the time domain position and the reference time domain position. Therefore, the working modes of the terminal equipment divided according to the SSB candidate sets are different, so that the power consumption of different SSB candidate sets in a preset time period is different, and the terminal equipment can dynamically select the SSB candidate set with better power consumption or optimal power consumption from a plurality of SSB candidate sets according to needs (considering both complexity and performance).

In some embodiments, the plurality of selection conditions may be preset conditions. The plurality of selection conditions may also be conditions configured by the terminal device according to actual power consumption requirements. The embodiment of the present application does not limit this.

In an embodiment of the present application, the plurality of selection conditions in step 1101 may correspond to a plurality of selection conditions of the terminal device one to one; the working mode of the terminal equipment in the time interval between the time domain position of the first SSB candidate set and the reference time domain position is the same as the first working mode; the first SSB candidate set is determined based on a selection condition corresponding to the first working mode; the first operating mode is any one of a plurality of operating modes.

It will be appreciated that the terminal device may set the selection condition according to the operating mode it has. Thus, the terminal device determines an SSB candidate set according to the selection condition. And the working mode of the terminal device at the time interval between the time domain position of the SSB candidate set and the target actual position is the working mode corresponding to the selection condition for determining the SSB candidate set.

In other words, the terminal device may determine the SSB candidate set according to the operating mode it has, and the terminal device is still in the operating mode in the time interval between the time domain position of the SSB candidate set determined by the operating mode and the reference time domain position.

In some embodiments, the selection condition corresponding to each operation mode may be preset or configured in advance, and the selection condition of each operation mode is related to the type of the terminal device.

Illustratively, the operation mode of the terminal device may include an active mode, a light sleep mode, a deep sleep mode, and the like. And the terminal equipment always starts a monitoring function in the activation mode and receives signals transmitted by the network equipment. In the doze mode, the terminal device may turn off part of the listening function. In the deep sleep mode, the terminal device turns off the monitoring function and does not monitor any signal sent by the network device.

In some embodiments, the first selection condition for the activation mode may be that a time interval between the temporal location of the candidate set of SSBs and the reference temporal location is less than a first threshold. The second selection condition for the doze mode may include that a time interval between the temporal location of the SSB candidate set and the reference temporal location is greater than or equal to a first threshold and less than a second threshold. The third selection condition for the deep sleep mode may include that a time interval between a time domain position of the SSB candidate set and a reference time domain position is greater than or equal to the first threshold.

In some embodiments, the first threshold may be determined according to a minimum switching duration required for the terminal device to switch from the active mode to the doze mode; the second threshold value may be determined according to a minimum switching duration required for the terminal device to switch from the active mode to the deep sleep mode,

in some embodiments, the first threshold may be twice the minimum switching duration required for the terminal device to switch from the active mode to the doze mode. That is, the first threshold may be a minimum switching duration required for the terminal device to switch from the active mode to the shallow sleep mode and from the shallow sleep mode to the active mode.

The second threshold may be twice the minimum switching duration required for the terminal device to switch from the active mode to the deep sleep mode, and the second threshold may be the minimum switching duration required for the terminal device to switch from the active mode to the deep sleep mode and from the deep sleep mode to the active mode.

It can be understood that, according to a first selection condition corresponding to the activation mode, the terminal device selects, from the SSB candidate set, an SSB candidate set in which a time interval between the time domain position and the reference time domain position is smaller than a first threshold, to obtain a first SSB candidate set. That is, the time interval between the time domain location of each SSB in the first SSB candidate set and the reference time domain location is less than the first threshold. Here, in a case where the time interval between the time domain position of the SSB candidate set and the reference time domain position is smaller than the first threshold, the terminal device cannot perform switching from the active mode to the light sleep mode, switching from the light sleep mode to the active mode, further switching from the active mode to the deep sleep mode, and switching from the deep sleep mode to the active mode within the time interval (switching of the active mode and the deep sleep mode takes longer time). Therefore, the terminal device is in the active mode for the time interval between the time domain position of the first SSB candidate set and the reference time domain position, and continuously listens to the signal transmitted by the network device.

In addition, the terminal device selects an SSB candidate set from the SSB candidate set according to a second selection condition corresponding to the doze mode, where a time interval between the time domain position and the reference time domain position is greater than or equal to a first threshold and smaller than a second threshold, and obtains a second SSB candidate set. It can be understood that the time interval between the time domain position of each SSB in the second SSB candidate set and the target monitored time domain position is less than the second threshold, that is, the terminal device cannot switch from the active mode to the deep sleep mode and from the deep sleep mode to the active mode within the time interval. In addition, the time interval between the time domain position of each SSB in the second SSB candidate set and the reference time domain position is greater than or equal to the first threshold, that is, the terminal device may switch from the active mode to the doze mode and from the doze mode to the active mode within the time interval. Therefore, the terminal device may be in a doze mode in a time interval between the time domain position of the second SSB candidate set and the reference time domain position, and turn off a partial listening function to reduce power consumption.

And the terminal equipment selects an SSB candidate set of which the time interval between the time domain position and the reference time domain position is larger than or equal to a second threshold value from the SSB candidate set according to a third selection condition corresponding to the deep sleep mode to obtain a third SSB candidate set. It is understood that the time interval between the time domain position of each SSB in the third SSB candidate set and the target monitored time domain position is greater than or equal to the second threshold, that is, the terminal device may switch from the active mode to the deep sleep mode and from the deep sleep mode to the active mode within the time interval. Therefore, the terminal device can be in the deep sleep mode in the time interval between the time domain position of the second SSB candidate set and the reference time domain position, and turn off all the listening functions, thereby further reducing power consumption.

It can be seen that, according to the at least two SSB candidate sets determined by the operation mode, the operation mode of the terminal device is different between the time domain position of the different SSB candidate sets and the reference time domain position. In this way, the diversity and richness of the determined at least two SSB candidate sets may be improved.

In an embodiment of the present application, referring to fig. 8, before determining, in step 120, power consumption amounts of each SSB candidate set in a preset time period based on a windowing power consumption time sequence corresponding to each SSB candidate set, the following steps may be further performed:

step 140, determining the working modes of the terminal device at different time domain positions within a preset time period based on the time position relationship between the time domain position of each SSB candidate set and the reference time domain position;

step 150, determining the power consumption of the terminal device at different time domain positions within a preset time period based on the power consumption required by different working modes, so as to obtain the windowing power consumption time sequence corresponding to each SSB candidate set.

It can be understood that, after determining a plurality of SSB candidate sets, the terminal device may divide different operation modes for the terminal device according to a time position relationship between a time domain position of each SSB candidate set and a reference time domain position.

In a possible implementation manner, in a scenario where the SSB candidate set is a presynchronization SSB candidate set, the terminal device may divide the working mode according to a position relationship between a time domain position of each presynchronization SSB candidate set and a time domain position of the target listening opportunity. Wherein the target listening opportunity comprises a paging listening opportunity and/or a persistent listening opportunity.

Specifically, the terminal device may determine the SSB candidate set for pre-synchronization and the distribution of the target monitoring occasions within a preset time period, and determine that the time domain positions of the SSB candidate set for pre-synchronization and the target monitoring occasions are the active mode. And determining the working mode of the SSB candidate set for pre-synchronization in the time interval according to the relation between the time interval between the time domain position of the SSB candidate set for pre-synchronization and the time domain position of the target monitoring opportunity and the first threshold and the second threshold. That is, if the time interval is smaller than the first threshold, the operating mode of the SSB candidate set for pre-synchronization in the time interval is determined to be the active mode, if the time interval is greater than or equal to the first threshold and smaller than the second threshold, the operating mode of the SSB candidate set for pre-synchronization in the time interval is determined to be the light sleep mode, and if the time interval is greater than or equal to the second threshold, the operating mode of the SSB candidate set for pre-synchronization in the time interval is determined to be the deep sleep mode.

In addition, the terminal device determines that the terminal device is in the deep sleep mode at other time domain positions. Thus, by the above manner, the working mode is divided for each SSB candidate set for presynchronization, and the working mode corresponding to each SSB candidate set for presynchronization can be obtained.

In some embodiments, if the candidate set of SSBs for pre-synchronization is determined by the selection condition corresponding to the operation mode, the operation mode between the time domain position of the candidate set of SSBs for pre-synchronization and the time domain position of the target listening opportunity may be directly determined as the operation mode corresponding to the selection condition.

For example, referring to fig. 6A, in the case where the SSB1 is determined as the first SSB candidate set for pre-synchronization, the terminal device may determine to be in the deep sleep mode before the time domain position of the SSB1, and at a time before the time domain position start time of the SSB1 arrives, the terminal device may wake up from the deep sleep mode and enter the active mode at the time domain position of the SSB1 to receive the SSB 1. Further, since the time interval between the temporal location of the SSB1 and the temporal location of the PF/PO/MO is small, the terminal device continues to be in the active mode after the pre-synchronization is completed until the PF/PO/MO ends. And the terminal equipment enters a deep sleep mode after the PF/PO/MO is finished.

In another possible implementation manner, in a scenario where the SSB candidate set is an SSB candidate set for neighbor cell measurement, the terminal device may divide the working mode according to a time interval between a time domain position of the first SSB candidate set and a time domain position of each SSB candidate set for neighbor cell measurement. The first SSB candidate set is an SSB candidate set determined by the terminal device for pre-synchronization.

Specifically, the terminal device may determine the distribution conditions of the SSB candidate set for the neighbor cell measurement and the first SSB candidate set in a preset time period, and determine that the time domain position where the SSB candidate set for the neighbor cell measurement and the first SSB candidate set are located is the active mode. And determining the working mode of the SSB candidate set for measuring the adjacent regions in the time interval according to the relation between the time interval between the time domain position of the first SSB candidate set and the time domain position of the SSB candidate set for measuring the adjacent regions and the first threshold and the second threshold. That is, if the time interval is smaller than the first threshold, the working mode of the SSB candidate set for neighbor cell measurement in the time interval is determined to be the active mode, if the time interval is greater than or equal to the first threshold and smaller than the second threshold, the working mode of the SSB candidate set for neighbor cell measurement in the time interval is determined to be the light sleep mode, and if the time interval is greater than or equal to the second threshold, the working mode of the SSB candidate set for neighbor cell measurement in the time interval is determined to be the deep sleep mode.

In addition, the terminal device determines that the terminal device is in the deep sleep mode at other time domain positions. Therefore, by the above manner, the working mode is divided for each SSB candidate for neighbor measurement, and the working mode corresponding to each SSB candidate set for neighbor measurement can be obtained.

For example, referring to fig. 6B, in the case of determining the SSB4 as the candidate set of SSBs for neighbor measurement 1, the terminal device may determine that the terminal device is in the deep sleep mode before the time domain position of the first SSB, and at a time before the start time of the time domain position of the first SSB arrives, the terminal device may wake up from the deep sleep mode and enter the active mode at the time domain position of the first SSB to receive the first SSB for pre-synchronization. Further, since the time interval between the time domain location of the first SSB and the time domain location of the SSB4 is small, the terminal device continues to be in the active mode after the pre-synchronization is completed until the end of the SSB4 is received. And the terminal device enters the deep sleep mode upon receiving the SSB 4.

In the embodiment of the application, because different working modes have different requirements on the processing capacity of the terminal device, the power consumption of the terminal device in different working modes is different. The terminal device may determine a power consumption time sequence within a preset time period based on the power consumption corresponding to each operating mode. Namely, the power consumption of the terminal device at different time domain positions within a preset time period, and the power consumption time sequence of each SSB is obtained.

It should be noted that the power consumption of different operation modes may be a predefined value, or may be a value determined by the terminal device according to an actual situation. The embodiment of the present application does not limit this.

For example, referring to fig. 6A, when SSB1 is used as the SSB candidate set for pre-synchronization 1, the windowing power consumption timing sequence corresponding to SSB1 can be shown by referring to curve 61 in fig. 6A; when the SSB2 is used as the SSB candidate set for presynchronization 2, the power consumption timing sequence corresponding to the SSB2 can be referred to as the curve 62 in fig. 6A; when the SSB3 is used as the SSB candidate set for pre-synchronization No. 3, the power consumption timing corresponding to the SSB3 can be referred to as a curve 63 in fig. 6A.

Referring to fig. 6B, when the SSB4 is used as the SSB candidate set for the 1 st neighbor cell measurement, the power consumption time sequence corresponding to the SSB4 may be shown by referring to a curve 64 in fig. 6B; when the SSB5 is used as the SSB candidate set for the 2 nd neighbor measurement, the power consumption time sequence corresponding to the SSB5 can be referred to as a curve 65 in fig. 6B; when the SSB6 is used as the SSB candidate set for the 3 rd neighbor measurement, the power consumption timing sequence corresponding to the SSB6 can be shown by referring to the curve 66 in fig. 6B.

In some embodiments, the determining, in step 120, the power consumption amount corresponding to each SSB candidate set in the preset time period based on the windowing power consumption timing sequence corresponding to each SSB candidate set may be implemented by:

respectively determining a windowing power consumption curve corresponding to each SSB candidate set in the preset time period based on the power consumption time sequence corresponding to each SSB;

and calculating the area of a closed region formed on a time domain axis by the power consumption curve to obtain the power consumption corresponding to each SSB candidate set.

In a possible implementation manner, the terminal device may determine the power consumption curve according to the windowing power consumption timing sequence corresponding to each SSB candidate set, that is, the power consumption at different time domain positions within a preset time period.

Illustratively, referring to FIG. 6A, the power consumption curve for SSB1 is shown as curve 61 in FIG. 6A. The power consumption curve for SSB2 is shown as curve 62 in fig. 6A. The power consumption curve for SSB3 is shown as curve 63 in fig. 6A.

In some embodiments, the terminal device may obtain the power consumption corresponding to the target SSB candidate set by calculating an area of a closed region formed by the power consumption curve and the time domain axis. Here, the terminal device may calculate the area by an integral method.

In an embodiment of the present application, a power consumption control method is further provided. Referring to the flowchart shown in fig. 9, a power consumption control method provided in an embodiment of the present application may include the following steps:

step 901, the terminal device determines to enter an idle state.

Step 902, the terminal device determines the time domain position of the PF/PO/MO.

Here, the terminal device may determine the time domain position of the PF/PO according to the network configuration and the ID of the terminal device, or calculate the time domain position of the MO according to the beam in which the terminal device is currently located.

Step 903, the terminal device determines a plurality of SSB candidate sets for pre-synchronization.

Here, the terminal device may determine a plurality of SSB candidate sets for pre-synchronization according to an operation mode it has. If the terminal device has N operating modes, a maximum of N pre-synchronization SSB candidate sets may be determined.

Illustratively, the terminal device may include three modes of operation: an active mode, a light sleep mode, and a deep sleep mode. The terminal device may determine selection conditions corresponding to the three operation modes, and determine the SSB candidate set for pre-synchronization based on the three selection conditions.

In the embodiment of the present application, the terminal device needs to perform pre-synchronization processing based on the SSB candidate set, and receive a paging message after the pre-synchronization. The terminal device needs to determine a plurality of SSB candidate sets for pre-synchronization among a plurality of SSBs preceding the time domain location of the PF/PO/MO. Based on this, in this scenario, the first selection condition corresponding to the activation mode may be that a time interval between the time domain position of the SSB candidate set and the time domain position of the PF/PO/MO is smaller than a first threshold. The second selection condition for the doze mode may include that a time interval between the temporal location of the SSB candidate set and the temporal location of the PF/PO/MO is greater than or equal to a first threshold and less than a second threshold. The third selection condition for the deep sleep mode may include that a time interval between a time domain position of the SSB candidate set and a time domain position of the PF/PO/MO is greater than or equal to the first threshold.

Referring to fig. 6A, if the SSB1 is located before the time domain location of the PF/PO/MO, and the time interval between the time domain location of the SSB1 and the time domain location of the PF/PO/MO is smaller than the first threshold, the terminal device may select the SSB1 as the first pre-synchronization candidate set. Specifically, the terminal device may perform presynchronization after receiving the SSB1, and after the presynchronization is completed, the terminal device may remain in the active mode until entering the deep sleep mode after receiving the paging message.

The SSB2 is located before the temporal location of the PF/PO/MO, and the time interval between the temporal location of the SSB2 and the temporal location of the PF/PO/MO is greater than the first threshold and less than the second threshold, satisfying the second selection condition. The terminal device may select SSB2 as the second pre-synchronization candidate set. Specifically, the terminal device receives the SSB2 for pre-synchronization, after the pre-synchronization is completed, the terminal device enters the light sleep mode until the time domain position of the PO/MO, the terminal device enters the active mode again to receive the paging message, and after the paging message is received, the terminal device enters the deep sleep mode again.

The SSB3 is located before the temporal location of the PF/PO/MO, and the time interval between the temporal location of the SSB3 and the temporal location of the PF/PO/MO is greater than the second threshold, satisfying a third selection condition, and the terminal device may select the SSB3 as a third pre-synchronization candidate set. Specifically, the terminal device may receive the SSB3 for pre-synchronization, and immediately enter the deep sleep mode after the pre-synchronization is completed, until the time domain location of the PO/MO wakes up again to enter the active mode and receives the paging message, and then enter the deep sleep mode after the paging message is received.

Step 904, the terminal device determines the power consumption amount corresponding to each of the plurality of SSB candidate sets for pre-synchronization.

For example, the power consumption curve corresponding to SSB1 (i.e., the first SSB candidate set for presynchronization) is shown as curve 61 in fig. 6A. The power consumption curve for SSB2 (i.e., the second candidate set of SSBs for presynchronization) is shown as curve 62 in fig. 6A. The power consumption curve corresponding to SSB3 (i.e., the third SSB candidate set for presynchronization) is shown as curve 63 in fig. 6A. The terminal device may calculate the areas formed by the curve 61, the curve 62, and the curve 63 and the time domain axis, respectively, to obtain the power consumption amounts corresponding to the 3 SSB candidate sets for pre-synchronization, respectively.

Step 905, the terminal device selects the SSB candidate set for pre-synchronization with the lowest power consumption as the target SSB candidate set for pre-synchronization.

It will be appreciated that the terminal device may dynamically select an optimal pre-synchronization via a comparison of the power consumption. For example, the SSB1 may be selected as the target SSB for pre-synchronization by the terminal device with the lowest amount of power consumption corresponding to the SSB 1. Thus, the terminal device can perform presynchronization at the receiving SSB1, and after the presynchronization is completed, the terminal device remains in the active mode until the terminal device enters the deep sleep mode after the paging message is received.

Step 906, the terminal device judges whether to perform neighbor measurement.

Here, if the terminal device needs to perform the neighbor cell measurement, step 907 is executed, and if the terminal device does not need to perform the neighbor cell measurement, step 910 is executed.

Step 907, the terminal device determines a plurality of SSB candidate sets for neighbor measurement.

Similar to determining the SSB candidate set for pre-synchronization, the terminal device may determine a plurality of SSB candidate sets for neighbor cell measurement according to the working mode of the terminal device. If the terminal device has N operating modes, a maximum of N SSB candidate sets for neighbor measurement may be determined.

Illustratively, the terminal device may include three modes of operation: an active mode, a light sleep mode, and a deep sleep mode. The terminal device may determine selection conditions corresponding to the three operating modes, and determine the SSB candidate set for the neighbor cell measurement based on the three selection conditions.

In the embodiment of the present application, the terminal device needs to perform the neighbor cell measurement processing based on the SSB candidate set, and the neighbor cell measurement needs to be completed when the terminal device and the network device are synchronized. The terminal device needs to determine a candidate set of SSBs for performing neighbor cell measurements after the time domain location of the first candidate set of SSBs. Based on this, in this scenario, the fourth selection condition corresponding to the activation mode may be that a time interval between the time domain position of the first SSB candidate set and the time domain position of the SSB candidate set is smaller than the first threshold. A fifth selection condition for the doze mode may be that a time interval between the time domain positions of the first SSB candidate set and the time domain positions of the SSB candidate set is greater than or equal to a first threshold and less than a second threshold. A sixth selection condition for the deep sleep mode may be that a time interval between a time domain position of the first SSB candidate set and a time domain position of the SSB candidate set is greater than or equal to the first threshold.

Referring to fig. 6B, the SSB4 is located after the temporal location of the first SSB, and the time interval between the temporal location of the first SSB and the temporal location of the SSB4 is smaller than the first threshold, which satisfies the fourth selection condition. The terminal device may select SSB4 as the candidate set of SSBs for first neighbor measurement. Specifically, after the first SSB is successfully received, the terminal device may keep the active mode until receiving the SSB4 to perform the neighbor cell measurement, and enter the deep sleep mode after the neighbor cell measurement is completed.

The SSB5 is located after the time domain position of the first SSB, and the time interval between the time domain position of the first SSB and the time domain position of the SSB5 is greater than the first threshold and less than the second threshold, which satisfies the fifth selection condition. The terminal device may select SSB5 as the candidate set of SSBs for second neighbor measurement. Specifically, the terminal device may enter the light sleep mode after the first SSB is received, and enter the active mode from the light sleep mode at the time domain position of the SSB5 to receive the SSB5 for performing the neighbor cell measurement, and enter the deep sleep mode after the neighbor cell measurement is completed.

The SSB6 is located after the temporal location of the first SSB, and the time interval between the temporal location of the first SSB and the temporal location of the SSB6 is greater than the second threshold, which satisfies the sixth selection condition. The terminal device may select SSB6 as the third neighbor cell measurement SSB candidate set. Specifically, the terminal device may enter the deep sleep mode after the first SSB is received, wake up before the time domain position of the SSB6, and enter the active mode at the time domain position of the SSB6 to receive the SSB6 for the neighbor cell measurement, and enter the deep sleep mode after the neighbor cell measurement is completed.

Step 908, the terminal device determines power consumption amounts corresponding to the plurality of SSB candidate sets for neighbor measurement.

For example, the power consumption curve corresponding to the SSB4 (i.e., the SSB candidate set for the first neighbor cell measurement) is shown as curve 64 in fig. 6B. The power consumption curve corresponding to the SSB5 (i.e., the SSB candidate set for the second neighbor cell measurement) is shown as curve 65 in fig. 6B. The power consumption curve corresponding to the SSB6 (i.e., the third neighbor measurement SSB candidate set) is shown as curve 66 in fig. 6B.

The terminal device may calculate the areas formed by the curve 64, the curve 765, and the curve 66 and the time domain axis, respectively, to obtain the power consumption amounts corresponding to the SSB candidate sets for the three neighbor cell measurements, respectively.

Step 909, the terminal device selects the SSB candidate set for the neighbor measurement with the lowest power consumption as the target SSB candidate set for the neighbor measurement.

It can be understood that, through the comparison of the power consumption, the terminal device may dynamically select an optimal neighbor cell measurement candidate set. For example, the SSB4 has the lowest power consumption, and the terminal device may select the SSB4 as the target SSB candidate set for neighbor cell measurement. Thus, the terminal device can perform the neighbor cell measurement after receiving the SSB4, and after the neighbor cell measurement is completed, the terminal device keeps the active mode until entering the deep sleep mode after the paging message is received.

Step 910, the terminal device receives the paging message and performs the neighbor cell measurement based on the determined target SSB candidate set for presynchronization or the target SSB candidate set for presynchronization and the target SSB candidate set for neighbor cell measurement.

Therefore, in the power consumption control method provided by the embodiment of the application, the terminal device may determine a plurality of SSB candidate sets based on the target monitoring opportunity, where each SSB candidate set corresponds to a different working mode; in this way, the terminal device may respectively determine the power consumption amount corresponding to each SSB based on the working mode corresponding to each SSB candidate set; further determining an SSB candidate set with power consumption meeting preset conditions from the plurality of SSB candidate sets to obtain a target SSB candidate set; finally, the terminal device may receive the target SSB candidate set based on the working mode corresponding to the target SSB candidate set, and listen to the signal at the target listening opportunity. That is, the terminal device may dynamically select an appropriate SSB candidate set according to the power consumption amounts of the plurality of SSB candidate sets, and perform power consumption control based on the selected appropriate SSB candidate set, thereby reducing the power consumption of the terminal device and extending the standby time of the terminal device.
