FIG. 1 shows a network architecture to which this embodiment of the present application may apply. As shown in FIG. 1 , the network architecture provided in this embodiment includes: a network device 101 and a terminal device 102 . The terminal devices involved in the embodiments of this application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other electronic devices connected to wireless modems with wireless communication functions, as well as various forms of user communication devices ( terminal device) or mobile station (Mobile Station, MS) and so on. The network device involved in the embodiment of the present application is a device deployed in a wireless access network to provide a wireless communication function for a communication device. In the embodiment of the present application, the network device may be, for example, the base station shown in FIG. 1 , and the base station may include electronic devices such as various forms of macro base stations, micro base stations, relay stations, and access points.

FIG. 2 shows a service scenario where the method for selecting an SSB candidate set provided by this application may be applicable. The method provided by this embodiment of the application can be applied to a discontinuous reception (Discontinuous Reception, DRX) mechanism of a terminal device. The method provided in the embodiment of the present application can be applied to an idle state DRX mechanism and a connected state DRX (Connected DRX, C-DRX) mechanism.

Wherein, the idle state DRX mechanism is the paging mechanism. Figure 2 shows a DRX cycle. In the paging mechanism, the communication device in the idle state only monitors the Physical Downlink Control Channel (PDCCH) in a specific period of time (such as the paging listening opportunity) to receive paging call message. At other times, the monitoring function can be turned off and the PDCCH is not monitored.

In addition, in the connected state DRX mechanism, the terminal device can monitor the PDCCH within a specific period of time (for example, the continuous monitoring opportunity C-DRX on-duration) to receive information transmitted by the network device. Do not monitor the PDCCH at other times (ie, non-monitoring occasions).

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

Usually, the terminal device will determine its working mode (such as deep sleep mode, light sleep mode, activation mode, etc.) according to different application scenarios. Different working modes have different demands on the processing capability of the terminal equipment. For example, in the active mode, the terminal equipment needs to be able to quickly respond to requests, which requires a higher processing capability. Capacity requirements are low. Among them, the terminal device can adjust the frequency and/or voltage of the chip through Dynamic Voltage and Frequency Scaling (DVFS) technology to adjust the processing capacity of the terminal device, and achieve the purpose of energy saving under the premise of meeting the demand for processing capacity.

Exemplarily, the active mode requires the terminal device to respond quickly to the request, and in this mode, the terminal device can adjust the frequency and/or voltage of the chip to make the frequency and/or voltage of the chip reach the highest. In the deep sleep mode, the terminal device does not need to respond to the request. In this mode, the terminal device can adjust the frequency and/or voltage of the chip to make the frequency and/or voltage of the chip the lowest. In addition, the light sleep mode does not require the communication device to respond to all requests, but can respond to part of the requests. Therefore, in this mode, the terminal device can adjust the frequency and/or voltage of the chip to be lower than the frequency and/or voltage corresponding to the active mode, And higher than the frequency and/or voltage corresponding to the deep sleep mode.

It can be understood that, when the terminal device switches between the active mode, the light sleep mode, and the deep sleep mode, the terminal device may continuously adjust the frequency and/or voltage of the chip, so that the terminal device is in different modes. Viewed on the two-dimensional distribution diagram of time versus frequency and/or voltage, the adjustment of frequency or voltage by terminal equipment is similar to windowing. In different working modes, the chip frequency and/or voltage corresponding to windowing are different.

Exemplarily, in the service scenario shown in FIG. 2, the terminal device can increase the frequency and/or voltage at the time domain position of the paging listening opportunity/continuous listening opportunity, that is, open the window to the maximum, so that the terminal device is in Active mode to monitor the PDCCH. In addition, the terminal device can reduce the frequency and/or voltage of the chip in the terminal device at other time domain positions other than the paging monitoring timing/continuous monitoring timing, so that the terminal device is in a deep sleep mode and the window is opened to the minimum, thereby saving power. consumption.

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 cell measurement based on handover requirements. That is to say, the terminal device needs to open a window to receive the pre-synchronization SSB before the paging monitoring opportunity or the continuous monitoring opportunity, so as to complete the pre-synchronization with the network device. In addition, when there is a need for handover, the terminal device can perform windowing to receive the neighbor cell measurement SSB, so as to realize the neighbor cell measurement.

Refer to FIG. 3 for a schematic flowchart of a method for selecting an SSB in the related art. The selection method of SSB in the related art may comprise the following steps:

Step 301, enter the 5G standby mode.

Step 302, determine the time domain position of the paging frame (Paging Frame, PF)/paging position (Paging Occasion, PO)/paging monitoring occasion (Monitoring Occasion, MO).

Here, the terminal device can determine the time-domain position of the PF/PO according to the network configuration and the identification information (Identity document, ID) of the terminal device, or calculate the time-domain position of the MO according to the current beam.

Step 303: Determine the received number of pre-synchronized SSBs according to the time domain positions of the PO/PF/MO.

In the related art, the terminal device may determine a preset number (for example, one or two) of SSBs for pre-synchronization according to the time domain position of the PO/PF/MO. For ease of expression, the present application will refer to the SSB determined for pre-synchronization as pre-synchronization SSB. Among them, the pre-synchronization SSB is used to realize the pre-synchronization between the terminal device and the network device, and the terminal device can perform automatic gain control (Automatic Gain Control, AGC) or automatic frequency control (Automatic Frequency Control, AFC) according to the pre-synchronization SSB and so on.

Step 304: Select a pre-synchronization SSB according to the received number of pre-synchronization SSBs.

Here, the terminal device may determine the pre-synchronization SSB that satisfies the received number according to the determined received number of pre-synchronized SSBs.

Step 305, judging whether to perform neighbor cell measurement.

Here, if the terminal device needs to perform neighbor cell measurement, step 306 is performed; if the terminal device does not perform neighbor cell measurement, step 308 is performed.

Step 306, according to the time domain position of the PO/PF/MO, determine the number of received neighbor cell measurement SSBs.

Here, in the case that neighbor cell measurement needs to be performed, the terminal device also needs to determine the SSB for neighbor cell measurement after PO/PF/MO. For ease of expression, the present application will refer to the SSB determined for neighboring cell measurement as the neighboring cell measurement SSB. Exemplarily, the terminal device may select a preset number of neighboring cells to measure the SSB according to the time domain position of the PO/PF/MO.

Step 307 , based on the received number of SSBs for neighboring cells, select a neighboring cell for measuring SSBs.

Here, the terminal device may determine, according to the determined received quantity of measured SSBs of neighboring cells, the measured SSBs of neighboring cells satisfying the received quantity.

Step 308, receiving the selected pre-synchronization SSB and/or neighbor cell measurement SSB.

After determining the pre-synchronization SSB and/or the neighbor cell measurement SSB, the terminal device can compare with the determined SSB (it can be the pre-synchronization SSB or the neighbor cell measurement SSB) according to the time domain position of PF/PO/MO The positional relationship between the time domain positions determines the frequency and/or voltage of the terminal device at different time domain positions. Corresponding to the change of frequency and/or voltage, the terminal device can have multiple operating modes, such as deep sleep mode, Light sleep mode, active mode, etc. Furthermore, the terminal device may receive the determined SSB according to the determined frequency and/or voltage magnitude at different time domain positions. Afterwards, the terminal device can perform pre-synchronization and/or neighbor cell measurement based on the received SSB.

Exemplarily, in a scenario where the terminal device does not need to perform neighbor cell measurement, referring to the timing diagram of windowing power consumption of the terminal device in a related art shown in FIG. 4A , the terminal device can select two SSBs located before the PF, As a pre-sync SSB.

Wherein, the terminal device can wake up from the deep sleep mode before the time domain position of the first pre-synchronization SSB arrives, and the terminal device can be in the active mode when the first pre-synchronization SSB (SSB1 in the figure) arrives, and The first pre-sync SSB (SSB1 in the illustration) is received in active mode. Since the time domain positions of the two pre-synchronization SSBs (SSB1 and SSB2 in the illustration) in Figure 4A are relatively close, the terminal device can immediately enter the Light sleep mode. It can be understood that in the light sleep mode, the terminal device can adjust the frequency and/or pressure of the chip to turn off part of the monitoring function and save the power consumption of the terminal device. When the start moment of the time domain position of the second pre-synchronization SSB (SSB2 in the figure) arrives, the terminal device can immediately enter the active mode from the light sleep mode, and receive the second pre-synchronization SSB ( SSB2 in the illustration). After the end device receives the second pre-synchronization SSB, it can enter the light sleep mode again to reduce power consumption. When the time domain position of the PF is reached, the terminal device can enter the active mode from the light sleep mode again to listen to the paging message, and after the PO in the PF is over, the terminal device enters the deep sleep mode until the next DRX cycle corresponding Presync SSB arrives. In the deep sleep mode, the terminal device turns off the monitoring function, and the power consumption is the lowest.

Exemplarily, in the scenario where the terminal device needs to perform neighbor cell measurement, referring to the power consumption sequence diagram of the terminal device in another related art shown in FIG. 4B , the terminal device selects the pre-synchronization SSB (SSB1' in the illustration ), the first SSB (SSB2' in the figure) after the pre-synchronization SSB can be used as the neighboring cell measurement SSB.

Among them, the terminal device can wake up from the deep sleep mode before the time domain position of the pre-synchronization SSB arrives, and the terminal device can be in the active mode when the pre-synchronization SSB (SSB1' in the figure) arrives, and receive in the active mode Pre-synchronize the SSB (SSB1' in the figure), and perform synchronization processing. In addition, the pre-synchronization SSB is relatively close to the MO time domain position in the PF. After the terminal device receives the pre-synchronization SSB in the active mode, it can immediately enter the light sleep mode, which saves power consumption and facilitates fast access when the PF arrives. Activate mode. Before the PF arrives, the terminal device can enter the active mode from the light sleep mode to listen to the paging message. Since the time domain positions of PF and neighbor cell measurement SSB (SSB2' in the figure) are closer, the terminal device has no time to switch the working mode. Therefore, after PF, the terminal device continues to be in the active mode and continues to monitor the downlink channel until Neighbor cell measurement SSB (SSB2' in the figure) is received. After receiving the neighbor cell measurement SSB, the terminal device can immediately enter the deep sleep mode until the corresponding pre-synchronization SSB of the next DRX cycle arrives.

From the above examples, it can be seen that the terminal equipment in the related art selects the SSB in a static manner (including pre-synchronization SSB and/or adjacent cell measurement SSB), and further, the terminal equipment selects the SSB according to the time domain position of the SSB and the PO/PF/MO The positional relationship between the time domain positions divides different working modes for the terminal equipment. In this way, the terminal device can use the DVFS technology to adjust the frequency and/or voltage of window opening in different working modes, so as to achieve the purpose of energy saving. However, in order to achieve the purpose of saving energy, the terminal equipment needs to frequently adjust the operating frequency and/or voltage of the chip, that is, frequently open the window, which leads to complex physical layer operations. How to balance the power consumption and performance of 5G terminal equipment is very important.

Based on this, an embodiment of the present application provides a method for selecting an SSB candidate set, which can be applied to a communication device. Wherein, the communication device may be implemented by means of software or hardware, and the communication device may be applied to the terminal device shown in FIG. 1 in the embodiment of the present application.

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

An embodiment of the present application provides a method for selecting a SSB candidate set. FIG. 5 is a schematic flow diagram of the method for selecting an SSB candidate set provided in an embodiment of the present application. Referring to FIG. 5 , in the embodiment of the present application, the communication The selection method for the device to determine the SSB candidate set may include the following step 110 .

In step 110, the communication device selects at least one SSB candidate set from at least two SSB candidate sets, wherein the at least two SSB candidate sets include a first SSB candidate set and a second SSB candidate set.

In step 110, the communication device selects at least one SSB candidate set from at least two SSB candidate sets, which may include:

Selecting the SSB candidate set of the smaller side in the mode switching times of windowing the first SSB candidate set and the mode switching times of windowing the second SSB candidate set;

or,

An SSB candidate set whose number of mode switching times for windowing is less than a threshold value of mode switching times is selected from at least two SSB candidate sets.

Here, the number of mode switching times refers to the number of switching times for the communication device to switch between different working modes (such as: deep sleep mode, active mode, light sleep mode).

It can be understood that the more the number of mode switching, the higher the complexity of the physical layer processing of the communication device, on the contrary, the less the number of mode switching, the lower the complexity of the physical layer processing of the communication device.

In this embodiment of the present application, the communication device may select an SSB candidate set with the least number of mode switching times from at least two SSB candidate sets as the SSB candidate set received by the communication device. The communication device may also select an SSB candidate set whose mode switching times are less than a preset mode switching times threshold from at least two SSB candidate sets, as the SSB candidate set received by the communication device.

It can be understood that, in the embodiment of the present application, the communication device can compare the mode switching times of at least two SSB candidate sets, and dynamically select the SSB candidate set with a smaller mode switching frequency from the at least two SSB candidate sets as the communication device needs. Received SSB candidate set. In this way, the number of mode switching times of the communication device during the communication process is reduced, the performance of the communication device is guaranteed, and the implementation complexity is reduced.

In some embodiments, the above-mentioned SSB candidate set may be a pre-synchronization SSB candidate set, wherein the pre-synchronization SSB candidate set is used for pre-synchronization, that is, to realize pre-synchronization between the communication device and the network device; the above-mentioned SSB candidate set may also be The neighboring cell measurement SSB candidate set; wherein, the neighboring cell measurement SSB candidate set is used for the neighboring cell measurement, and realizes the measurement of the neighboring cell by the communication device. The embodiment of the present application does not limit the type of the SSB candidate set.

In addition, the embodiment of the present application also provides a method for selecting an SSB candidate set, which can be applied to a communication device. Wherein, the communication device may be implemented by means of software or hardware, and the communication device may be integrated into the terminal device shown in FIG. 1 in the embodiment of the present application.

An embodiment of the present application also provides a method for selecting an SSB candidate set. FIG. 6 is a schematic flow diagram of the second method for selecting an SSB candidate set provided by the embodiment of the present application. Referring to FIG. 6 , in the embodiment of the present application, The method for the communication device to determine the SSB candidate set may include the following step 210 .

In step 210, the communication device selects at least one SSB candidate set from at least two SSB candidate sets, wherein the at least two SSB candidate sets include a first SSB candidate set and a second SSB candidate set.

In step 210, the communication device selects at least one SSB candidate set from at least two SSB candidate sets, which may include:

According to the channel quality and/or working state, select the SSB candidate set of the smaller side among the mode switching times of windowing the first SSB candidate set and the mode switching times of windowing the second SSB candidate set, or select the SSB candidate set for the second SSB candidate set An SSB candidate set that is smaller in the amount of power consumption for windowing the first SSB candidate set and the amount of power consumption for windowing the second SSB candidate set.

It should be understood that the SSB is information broadcast by the network device, and the reception of the SSB depends on the broadcast channel between the network device and the communication device. The channel quality mentioned in the embodiment of the present application refers to the channel quality of the broadcast channel between the network device and the communication device.

In the embodiment of the present application, the communication device may measure the channel state of the broadcast channel between the network device and the communication device to obtain the channel quality of the broadcast channel. Exemplarily, the channel quality may include but not limited to at least one of reference signal received power, reference signal received quality, path loss, and signal-to-interference-noise ratio. This embodiment of the present application does not limit it. Correspondingly, determining the number of received SSBs according to the channel quality may also be understood as determining the number of received SSBs according to the value of at least one of the above physical quantities characterizing the channel quality.

It should be pointed out that in the embodiment of the present application, the comparison of channel quality can also be understood as the comparison of the values of physical quantities used to characterize the channel quality. For example, if the channel quality is higher (better, better, etc.), it can be understood as The SINR is greater than the SINR threshold. This embodiment of the present application will not describe it in detail.

In addition, the working state may be the power consumption control state of the communication device. For example, the working state includes: a low-power working state and a non-low-power working state, wherein the low-power working state refers to a state in which the communication device needs to control power consumption. Scenes.

Exemplarily, when at least one of the following conditions is met, the communication device may determine that it is in a low power consumption state.

The power of the communication device is less than a preset power threshold;

The temperature of the communication device is higher than a preset temperature threshold;

The screen status of the communication device is off screen;

The communication device receives a switching instruction; the switching instruction is used to start the low power consumption mode.

The non-low-power working state refers to a scenario where the device does not need to control power consumption. Exemplarily, the non-low power consumption state may be a state where the communication device moves at a high speed and the user frequently operates, which is not limited in this embodiment of the present application.

In this embodiment of the present application, the communication device may select the SSB candidate set with the least number of mode switching times from at least two SSB candidate sets according to the channel quality and/or working state, as the SSB candidate set received by the communication device. The communication device may also select, from at least two SSB candidate sets, the SSB candidate set with the smallest power consumption for windowing, as the SSB candidate set received by the communication device, according to channel quality and/or working state.

It can be understood that, in the embodiment of the present application, the communication device may compare the number of mode switching times of at least two SSB candidate sets, or compare the power consumption of at least two SSB candidate sets for windowing, according to channel quality and/or working status , from at least two SSB candidate sets, dynamically select the SSB candidate set with a smaller number of mode switching times as the SSB candidate set that the communication device needs to receive, or dynamically select the SSB candidate set with lower power consumption as the SSB that the communication device needs to receive candidate set. In this way, the SSB candidate set dynamically selected according to the channel quality and/or working state can be adapted to the requirements of the communication device and achieve a balance between the number of mode switching times, power consumption and implementation complexity.

How the communication device determines at least two SSB candidate sets will be described in detail below.

In some embodiments, the communication device may select some SSBs from multiple SSBs configured by the network device to obtain the at least two SSB candidate sets. Wherein, one SSB candidate set may include at least one SSB, that is, one or more SSBs, which is not limited in this embodiment of the present application.

Exemplarily, referring to FIG. 7A , the communication device may select SSB1 and SSB2 as one SSB candidate set from SSB1 , SSB2 and SSB3 , and select SSB3 as another SSB candidate set. The communication device may also select SSB1 as the first SSB candidate set, select SSB2 as the second SSB candidate set, and select SSB3 as the third SSB candidate set from SSB1, SSB2 and SSB3.

That is to say, the communication device may arbitrarily select more than one SSB from multiple SSBs to obtain the at least two SSB candidate sets. The communication device may also select more than one SSB from multiple SSBs based on certain rules to obtain the at least two SSB candidate sets. The embodiment of the present application does not limit the manner of determining at least two SSB candidate sets.

In some embodiments, the communication device may determine at least two SSB candidate sets according to the time interval between the time domain position of the SSB and the reference time domain position.

Wherein, the reference time-domain position is the time-domain position of the monitoring occasion; wherein, the monitoring occasion includes a paging monitoring occasion and/or a continuous monitoring occasion. For example, the reference time domain location may be the time domain location of PO/PF/MO.

Exemplarily, the communication device may select an SSB whose time interval between the time domain position and the reference time domain position is less than a preset duration from the multiple SSBs to obtain the first SSB candidate set; and from the multiple SSBs, select the SSB with The time interval between the time-domain position and the reference time-domain position is greater than or equal to the SSB of the preset duration to obtain the second SSB candidate set. Exemplarily, the preset duration may be 3 milliseconds or any other length of time, which is not limited in this embodiment of the present application.

Here, in the at least two SSB candidate sets, the time intervals between different SSB candidate sets and the reference time domain position are different.

Optionally, the communication device needs to receive signals at the time domain position where the SSB candidate set is located and the reference time domain position, that is, the communication device has the maximum frequency and/or voltage at the time domain position where the SSB candidate set is located and the reference time domain position . The frequency and/or voltage for windowing and the number of mode switching times at other time domain positions need to be determined according to the time interval between the two. If the time interval between the two is longer, the communication device is set to be in a deep sleep mode, so that The frequency and/or voltage of windowing performed by the communication device during this time interval are the smallest, and the number of mode switching is relatively large. If the time interval between the two is moderate, the communication device can be set to be in a light sleep mode, so that the frequency and/or voltage of the communication device to open windows during this time interval is moderate. If the time interval between the two is short, the communication device can be set to be in the active mode continuously, so that the frequency and/or voltage of the communication device to open windows during this time interval is at the maximum state, and the number of mode switching times is the least.

Based on this, the time interval between different SSB candidate sets and the reference time domain position is different, and it can be ensured that the frequency and/or voltage at which the communication device performs windowing on the SSB candidate set at different time domain positions is different, thereby ensuring different The amount of power consumption for windowing the SSB candidate sets is different. At the same time, it can be ensured that the times of windowing of the SSB candidate sets by the communication device at different time domain positions are also different, thus ensuring that the communication device can dynamically select from at least two SSB candidate sets with different power consumption or times of windowing A candidate set of SSBs with lower power consumption or fewer mode switching times.

In some embodiments, the communication device may set multiple selection conditions in advance. At least two SSB candidate sets with different windowing power consumption amounts are determined by selection conditions.

Here, the selection condition is a condition that needs to be satisfied by the time interval between the time domain position of the SSB candidate set and the reference time domain position. For example, the selection condition may be that the time interval between the two is greater than a certain threshold, or smaller than a certain threshold. In this way, the communication device can determine the time interval between the time domain position of the SSB and the reference time domain position from the plurality of SSBs, and obtain the at least two SSB candidate sets from the SSBs satisfying each selection condition.

In some embodiments, the communication device can set selection conditions according to its working mode.

Exemplarily, the working mode of the communication device may include an active mode, a light sleep mode, a deep sleep mode, and the like. Wherein, in the active mode, the communication device can always turn on the monitoring function to receive signals transmitted by the network equipment. In the light sleep mode, the communication device may turn off some monitoring functions. In the deep sleep mode, the communication device turns off the monitoring function and does not monitor any signal sent by the network device.

In some embodiments, the first selection condition corresponding to the active mode may be that the time interval between the time domain position of the SSB and the reference time domain position is smaller than a first time interval threshold. The second selection condition corresponding to the light sleep mode may include that the time interval between the time domain position of the SSB and the reference time domain position is greater than or equal to the first time interval threshold and less than the second time interval threshold. The third selection condition corresponding to the deep sleep mode may include that the time interval between the time domain position of the SSB and the reference time domain position is greater than or equal to the first time interval threshold.

In some embodiments, the first time interval threshold can be determined according to the minimum switching duration required for the communication device to switch from the active mode to the light sleep mode; the second time interval threshold can be determined according to the time required for the communication device to switch from the active mode to the deep sleep mode. The minimum switching time is determined.

In some embodiments, the first time interval threshold may be twice the minimum switching time required for the communication device to switch from the active mode to the doze mode. That is to say, the first time interval threshold may be the minimum switching time required for the communication device to switch from the active mode to the doze mode, and from the doze mode to the active mode.

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

It can be understood that, according to the first selection condition corresponding to the active mode, the communication device selects SSBs whose time interval between the time domain position and the reference time domain position is smaller than the first time interval threshold from SSBs to obtain the first SSB candidate set. That is to say, the time interval between the time domain position of each SSB in the first SSB candidate set and the reference time domain position is smaller than the first time interval threshold. Here, when the time interval between the time domain position of the SSB candidate set and the reference time domain position is less than the first time interval threshold, the communication device cannot switch from the active mode to the light sleep mode within the time interval, and from Switch from light sleep mode to active mode, let alone switch from active mode to deep sleep mode, and switch from deep sleep mode to active mode (the switch between active mode and deep sleep mode takes longer). Therefore, the communication device can only be in the active mode during the time interval between the time domain position of the first SSB candidate set and the reference time domain position. At this time, the number of mode switching times of the communication device is the least, but the power consumption of windowing is relatively large , which can continuously monitor the signal sent by the network device.

In addition, the communication device selects from the SSB the time interval between the time domain position and the reference time domain position that is greater than or equal to the first time interval threshold and less than the second time interval threshold from the SSB according to the second selection condition corresponding to the light sleep mode. SSB to obtain 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 reference time domain position is smaller than the second time interval threshold, that is, the communication device cannot obtain from Switch from active mode to deep sleep mode, and from deep sleep mode to active mode. 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 time interval threshold, that is, the communication device can switch from the active mode within the time interval To the light sleep mode, and switch from the light sleep mode to the active mode, thereby increasing the number of mode switching times, so that the number of mode switching times of the communication device is greater than that when the communication device is always in the active mode. However, the communication device may be in a doze mode during the time interval between the time domain position of the second SSB candidate set and the reference time domain position, at which time the frequency and/or voltage of the communication device windowing the SSBs is moderate, to reduce power consumption.

The communication device selects the SSB whose time interval between the time domain position and the reference time domain position is greater than or equal to the second time interval threshold from the SSBs according to the third selection condition corresponding to the deep sleep mode, and obtains a third SSB candidate set. It can be understood that, the time interval between the time domain position of each SSB in the third SSB candidate set and the reference time domain position is greater than or equal to the second time interval threshold, that is, the communication device may be within the time interval from The active mode is switched to the deep sleep mode, and then switched from the deep sleep mode to the active mode, thereby increasing the number of mode switching times, so that the number of mode switching times of the communication device is greater than that when the communication device is always in the active mode. However, the communication device may be in a deep sleep mode during the time interval between the time domain position of the third SSB candidate set and the reference time domain position, and at this time, the frequency and/or voltage at which the communication device performs windowing is minimum, and the communication device may Turn off all monitoring functions to further reduce power consumption.

It can be seen that in the at least two SSB candidate sets determined according to the working mode, the working mode of the communication device between its time domain position and the reference time domain position in different SSB candidate sets is different, and the corresponding windowing frequency and/or Or voltage and mode switching times are also different. In this way, the diversity and richness of the determined at least two SSB candidate sets can be improved.

The following describes in detail how the communication device selects the SSB candidate set according to the channel quality.

In an embodiment of the present application, the communication device may select an SSB candidate set from at least two SSB candidate sets according to channel quality as the SSB candidate set that the communication device needs to receive.

In some embodiments, when the channel quality is greater than the first threshold, the SSB of the smaller one of the power consumption of windowing the first SSB candidate set and the power consumption of windowing the second SSB candidate set is selected candidate set.

That is to say, when the channel quality of the communication device is greater than the first threshold, it indicates that the channel quality of the communication device is better, which can ensure the stability of receiving signals. Therefore, at this time, the communication device may select an SSB candidate set with low power consumption, that is, select an SSB candidate set with a smaller power consumption for windowing as the SSB candidate set to be received. In this way, power consumption can be reduced while ensuring the performance of the communication device.

In some embodiments, the communication device may also select the SSB candidate set according to the power consumption, and select the SSB candidate set whose windowing power consumption is less than the power consumption threshold from at least two SSB candidate sets, as the SSB candidate set that the communication device needs to receive SSB candidate set. The power consumption threshold may be predefined by the communication device.

In some embodiments, the communication device may determine the amount of power consumption for windowing the SSB candidate set according to the time domain position of the SSB candidate set and the reference time domain position.

Here, the communication device may determine the magnitude of the frequency and/or voltage at the time domain position of the SSB candidate set and the reference time domain position, and the time domain position of the SSB candidate set according to the time domain position of the SSB candidate set and the reference time domain position. The magnitude of the frequency and/or voltage over the time interval between the domain location and the reference time domain location. Based on this, the communication device may obtain the power consumption of windowing each SSB candidate set by calculating the voltage or frequency of windowing in the entire time domain.

In some embodiments, the communication device may determine the power consumption curve corresponding to the SSB candidate set based on the power consumption sequence corresponding to the SSB candidate set, wherein the power consumption sequence is used to characterize the time sequence used by the communication device to evaluate the SSB candidate at different time domain positions The frequency and/or voltage of the set for windowing; furthermore, the communication device may perform time-domain integration on the power consumption curve to obtain the power consumption of the SSB candidate set for windowing.

It should be understood that the communication device needs to be in an active mode at the time domain position of the SSB candidate set and the reference time domain position, and the frequency and/or voltage are relatively high. Secondly, the communication device can be in any working mode between the time domain position of the SSB candidate set and the reference time domain position, and the specific working mode can be determined according to the time domain position of the SSB candidate set and the reference time domain position. The time interval is determined based on the relationship between the first time interval threshold and the second time interval threshold. Additionally, the communications device determines that it is in deep sleep mode at other temporal locations.

Wherein, if the time interval between the time domain position of the SSB candidate set and the reference time domain position is less than the first time interval threshold, it is determined that the working mode of the communication device within the time interval is the active mode, that is, within the time interval High frequency and/or voltage. If the time interval is greater than or equal to the first time interval threshold and less than the second time interval threshold, it is determined that the working mode of the communication device within the time interval is the light sleep mode, and the electrical frequency and/or voltage within the time interval are moderate . If the time interval is greater than or equal to the second time interval threshold, it is determined that the working mode of the communication device within the time interval is a deep sleep mode, and the frequency and/or voltage within the time interval are relatively small. In this way, the time sequence of power consumption for windowing each SSB candidate set can be obtained.

Exemplarily, as shown in FIG. 7A, in the case of determining SSB1 as a pre-synchronized SSB candidate set, the communication device may determine that it is in a deep sleep mode before the time domain position of SSB1, and perform windowing frequency and/or voltage Size A. At a certain moment before the initial moment of the time domain position of SSB1 arrives at the communication device, the communication device may wake up from the deep sleep mode, and enter the active mode at the time domain position of SSB1 to receive SSB1, in the process, The frequency and/or voltage at which the communication device performs windowing is increased from A to B. Further, since the time interval between the time domain position of SSB1 and the time domain position of PF/PO/MO is small, the communication device continues to be in the active mode after pre-synchronization is completed until the end of PF/PO/MO, during which , the frequency and/or voltage at which the communication device opens the window remains at B. The communication device enters the deep sleep mode after the PF/PO/MO ends, and at this time, the window opening frequency and/or voltage frequency of the communication device is reduced to A. It can be seen from FIG. 7A that the curve 61 is the power consumption timing curve of SSB1.

Exemplarily, as shown in FIG. 7B , in the case of determining SSB4 as a neighboring cell measurement SSB candidate set, the communication device may determine that it is in the deep sleep mode before the time domain position of the first SSB, and in the time domain position of the first SSB The magnitude of the frequency and/or voltage rate of the communication device prior to the time-domain position of the first SSB is A. Further, at a certain time before the initial moment of the time domain position of the first SSB arrives, the communication 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 One SSB for pre-synchronization. During this process, the frequency and/or voltage of the communication device is increased from A to B.

In addition, since the time interval between the time domain position of the first SSB and the time domain position of PF/PO/MO and SSB4 is small, the communication device continues to be in the active mode after the completion of the pre-synchronization, during which the communication The device maintains frequency and/or voltage at B until the end of SSB4 is received. Moreover, the communication device enters into a deep sleep mode after receiving SSB4, and at this time, the frequency and/or voltage of the communication device at a position in the time domain after SSB4 is reduced to A. It can be seen from FIG. 7B that the curve 64 is the power consumption timing curve of SSB4.

Based on the above method, the communication device can obtain a schematic diagram of a power consumption sequence corresponding to each SSB.

Exemplarily, as shown in FIG. 7A, when SSB1 is used as a pre-synchronized SSB candidate set, the power consumption sequence corresponding to SSB1 can refer to the curve 61 in FIG. 7A; when SSB2 is used as a pre-synchronized SSB candidate set, the power consumption sequence corresponding to SSB1 The power consumption sequence can be shown by reference to curve 62 in FIG. 7A ; when SSB3 is used as a pre-synchronization SSB candidate set, the power consumption sequence corresponding to SSB3 can be shown by reference to curve 63 in FIG. 7A .

Referring to Figure 7B, when SSB4 is used as a neighboring cell to measure the SSB candidate set, the power consumption sequence corresponding to SSB4 can be shown in curve 64 in Figure 7B; when SSB5 is used as a neighboring cell to measure the SSB candidate set, the power consumption corresponding to SSB5 The timing can be shown by reference to the curve 65 in FIG. 7B ; when SSB6 is used as a neighboring cell to measure the SSB candidate set, the power consumption timing corresponding to SSB6 can be shown by reference to the curve 66 in FIG. 7B .

Further, after obtaining the power consumption sequence of each SSB candidate set, the communication device may determine the power consumption sequence based on the power consumption sequence corresponding to each SSB candidate set, that is, the frequency and/or voltage at different time domain positions. consumption curve. Afterwards, the communication device can obtain the number of mode switching times of windowing for each SSB candidate set through the trend of the SSB power consumption curve.

It should be noted that the power consumption curve is consistent with the power consumption sequence, the difference is that the vertical axis of the power consumption sequence is the frequency and/or voltage of the communication device, while the vertical axis of the power consumption curve is the power consumption.

Exemplarily, referring to FIG. 7A , the power consumption curve corresponding to SSB1 may be consistent with the curve 61 in FIG. 7A . The power consumption curve corresponding to SSB2 is consistent with the curve 62 in FIG. 7A . The power consumption curve corresponding to SSB3 is consistent with the curve 63 in FIG. 7A .

In some embodiments, the communication device may integrate the time domain of the SSB power consumption curve to obtain the area of the enclosed area formed by the power consumption curve and the time domain axis, so as to obtain the power consumption for windowing each SSB candidate set.

It can be understood that, in the embodiment of the present application, the communication device can dynamically select the SSB candidate set according to the power consumption of windowing different SSB candidate sets, so that the SSB can be received according to the selected SSB candidate set, and can When the channel quality of the device is good, the performance of the communication device is guaranteed and the power consumption is reduced.

In some embodiments, if the channel quality is less than the second threshold, then select the SSB candidate of the side with the smaller number of mode switching times for windowing the first SSB candidate set and the smaller number of mode switching times for windowing the second SSB candidate set set.

Wherein, when the channel quality of the communication device is lower than the first threshold, it indicates that the channel quality of the communication device is poor, and the stability in the signal receiving process cannot be guaranteed. Therefore, at this time, the communication device can select the SSB candidate set with a smaller number of mode switching times, that is, select the SSB candidate set with the smaller number of mode switching times as the SSB candidate set that needs to be received, so as to avoid the SSB candidate set that needs to be received during the mode switching process because the hardware is not initialized. Successfully caused the problem that the reception of the SSB candidate set failed. In this way, while ensuring the stability of the communication device, the situation that the SSB is not received is avoided.

In some embodiments, the communication device may also obtain an SSB candidate set with a smaller number of mode switching times according to the second preset condition.

Exemplarily, if the SSB candidate set is selected according to the number of mode switching times, the SSB candidate set whose mode switching times are smaller than the mode switching times threshold for windowing is selected from at least two SSB candidate sets.

Here, the second preset condition is: the number of times of mode switching is less than the threshold value of the number of times of mode switching. The mode switching times threshold may be determined according to the minimum number of times the communication device switches between the deep sleep mode, the light sleep mode and the active mode during the process from receiving the SSB candidate set to completing listening to the paging message.

Wherein, the communication device selects the SSB candidate set according to the number of mode switching times, and selects the SSB candidate set whose windowed mode switching times are less than the mode switching times threshold from at least two SSB candidate sets, as the SSB candidate set that the communication device needs to receive.

In some embodiments, the communication device may obtain the number of mode switching times of each SSB candidate set in the entire time domain according to the time domain position of the SSB candidate set and the reference time domain position.

Specifically, it can be determined that in the entire time domain, the number of switching times for the communication device to switch between working modes is the number of mode switching times, wherein the workwear mode may include: a deep sleep mode, a light sleep mode and an active mode.

As described in the above embodiment, for example, as shown in FIG. 7A, when SSB1 is used as a pre-synchronized SSB candidate set, the power consumption sequence corresponding to SSB1 can be shown in curve 61 in FIG. 7A; SSB2 is used as a pre-synchronized SSB For the candidate set, the power consumption sequence corresponding to SSB1 can be shown by reference to curve 62 in FIG. 7A; when SSB3 is used as a pre-synchronized SSB candidate set, the power consumption sequence corresponding to SSB3 can be shown by reference to curve 63 in FIG. 7A.

In some embodiments, the communication device may obtain the number of mode switching times of each SSB candidate set through the trend of the SSB power consumption curve.

For example, as shown in FIG. 7A, when SSB1 is used as a pre-synchronized SSB candidate set, the power consumption sequence corresponding to SSB1 can be shown in curve 61 in FIG. 7A; according to the trend of curve 61, it can be obtained that the communication device is close to SSB1 Wake up from the deep sleep mode when SSB1 arrives, enter the active mode from the deep sleep mode, and complete the reception of SSB1 and paging messages in the active mode, and then enter the deep sleep mode. At this time, it can be obtained that the communication device switches modes twice during the process of completing the reception of the SSB1 and the paging message.

For example, as shown in FIG. 7B, when SSB4 is used as a neighboring cell to measure the SSB candidate set, the power consumption sequence corresponding to SSB4 can be shown in the curve 64 in FIG. 7B; according to the trend of the curve 64, it can be obtained that the communication device is close to Wake up from deep-sleep mode during the first SSB, enter active mode from deep-sleep mode when the first SSB arrives, and complete the reception of the first SSB and paging message in active mode, then receive SSB4 in active mode, to Complete neighborhood measurements. At this time, it can be obtained that the communication device switches modes twice during the process of completing receiving the first SSB and the paging message and receiving SSB4.

Based on the above method, the communication device can obtain the number of mode switching times corresponding to each SSB candidate set.

It can be understood that, in the embodiment of the present application, the communication device can dynamically select the SSB candidate set according to the number of mode switching times. In this way, receiving the SSB based on the selected SSB candidate set can ensure communication when the channel quality of the communication device is poor. Device stability to avoid situations where SSBs are not received.

In some embodiments, the first threshold and the second threshold may be the same threshold, or may be two different thresholds. When the first threshold and the second threshold are two different thresholds, and the channel quality is between the first threshold and the second threshold, the communication device may select the SSB candidate set according to the working state. Wherein, the first threshold and the second threshold may be determined according to the success rate of receiving signals by the communication device and the corresponding signal quality, for example, the first threshold may be the corresponding signal quality when the success rate of receiving signals by the communication device is 80%. The second threshold may be the corresponding signal quality when the success rate of receiving signals by the communication device is 50%.

The following describes in detail how the communication device selects the SSB candidate set according to the working state.

In an embodiment of the present application, the communication device may select an SSB candidate set from at least two SSB candidate sets according to the working state as the SSB candidate set that the communication device needs to receive.

In some embodiments, if the working state is a low-power working state, select the SSB of the smaller one of the power consumption of windowing the first SSB candidate set and the power consumption of windowing the second SSB candidate set candidate set.

Wherein, when the working state of the communication device is the low power consumption working state, it is necessary to control the power consumption of the communication device.

In some embodiments, the communication device may select the SSB candidate set with the smaller power consumption of windowing as the SSB candidate set to be received. Thus, power consumption is reduced.

In some other embodiments, the communication device may also select an SSB candidate set whose power consumption for windowing is smaller than a power consumption threshold from at least two SSB candidate sets. Here, the power consumption threshold may be predefined by the communication device.

It should be noted that, the manner of selecting a low-power SSB candidate set and the method of obtaining the power consumption of each SSB candidate set are as described in the above-mentioned embodiments, and will not be repeated here.

It can be understood that, in the embodiment of the present application, when the communication device is in the low power consumption state, it can dynamically select the SSB candidate set according to the power consumption of opening the window, so that the power consumption can be reduced.

In some embodiments, if the working state is a non-low-power working state, the number of mode switching times for windowing the first SSB candidate set and the number of mode switching times for windowing the second SSB candidate set are selected. SSB candidate set.

Wherein, when the working state of the communication device is a non-low power consumption working state, it means that the communication device does not control the power consumption. Therefore, an SSB candidate set with a smaller number of mode switching times can be selected. At this time, the communication device selects the SSB candidate set that is smaller in the number of mode switching times for windowing. In this way, the performance of the communication device and the success rate of receiving the SSB are guaranteed.

In some embodiments, the communication device may also obtain an SSB candidate set with a smaller number of mode switching times according to the second preset condition. Exemplarily, the communication device selects from at least two SSB candidate sets an SSB candidate set whose number of mode switching times for windowing is less than a threshold value of mode switching times.

It should be noted that the method of selecting the SSB candidate set with a small number of mode switching times and the method of obtaining the mode switching times of each SSB candidate set are as described in the above-mentioned embodiments, and will not be repeated here.

It can be understood that, in this embodiment of the present application, when the communication device is in a non-low power consumption state, it can dynamically select the SSB candidate set according to the number of mode switching times. In this way, communication device performance is guaranteed.

In an embodiment of the present application, referring to the schematic flowchart shown in FIG. 8, the method for selecting the SSB candidate set provided in the embodiment of the present application may include the following steps:

Step 701, the communication device determines to enter an idle state.

Step 702, the communication device determines the time domain position of the MO.

Step 703, the communication device determines multiple pre-synchronization SSB candidate sets.

Here, the communication device may determine multiple pre-synchronization SSB candidate sets according to the time interval between the time domain position of the SSB before the MO and the time domain position of the MO.

Wherein, the communication device may select an SSB whose time interval from the time domain position of the MO satisfies the selection condition from the SSBs before the MO according to the selection condition corresponding to the working mode, and obtain multiple pre-synchronization SSB candidate sets. If the communication device has N working modes, at most N pre-synchronization SSB candidate sets can be determined.

Exemplarily, the communication device may include three working modes: active mode, light sleep mode, and deep sleep mode. The communication device may determine selection conditions respectively corresponding to the three working modes, and determine the pre-synchronization SSB candidate set based on the three selection conditions.

In the embodiment of the present application, the communication device needs to perform pre-synchronization processing based on the SSB, and receive the paging message after the pre-synchronization. The communication device needs to determine multiple sets of pre-synchronized SSB candidates in multiple SSBs preceding the time domain position of the MO. Based on this, in this scenario, the first selection condition corresponding to the activation mode may be that the time interval between the time domain position of the SSB and the time domain position of the MO is less than the first time interval threshold. The second selection condition corresponding to the light sleep mode may include that the time interval between the time domain position of the SSB and the time domain position of the MO is greater than or equal to the first time interval threshold and less than the second time interval threshold. The third selection condition corresponding to the deep sleep mode may include that the time interval between the time domain position of the SSB and the time domain position of the MO is greater than or equal to the first time interval threshold.

As shown in FIG. 7A, SSB1 is located before the time domain position of MO, and the time interval between the time domain position of SSB1 and the time domain position of MO is less than the first time interval threshold, and the first selection condition is satisfied, then the communication device can select SSB1 serves as the first pre-synchronization candidate set. Wherein, the communication device may perform pre-synchronization after receiving SSB1, and after the pre-synchronization is completed, it will remain in the active mode until the paging message is received and enter the deep sleep mode.

SSB2 is located before the time domain position of MO, and the time interval between the time domain position of SSB2 and the time domain position of MO is greater than the first time interval threshold and smaller than the second time interval threshold, satisfying the second selection condition. The communications device may select SSB2 as the second pre-sync candidate set. Among them, the communication device receives SSB2 for pre-synchronization. After the pre-synchronization is completed, the communication device enters the light sleep mode until the time domain position of MO, and then enters the activation mode to receive the paging message, and then enters the deep sleep mode after receiving the paging message. .

SSB3 is located before the time domain position of MO, and the time interval between the time domain position of SSB3 and the time domain position of MO is greater than the second time interval threshold, the third selection condition is met, and the communication device can select SSB3 as the third pre-synchronization candidate set. Among them, the communication device can receive SSB3 for pre-synchronization, and enter the deep sleep mode immediately after the pre-synchronization is completed, until the time domain position of the MO wakes up again and enters the activation mode and receives the paging message, and then enters the deep sleep mode after receiving the paging message .

In step 704, the communication device determines a selection strategy for selecting a pre-synchronization SSB candidate set according to channel quality and working status.

Here, the communication device determines the selection strategy according to the channel quality and the working state, and the selection strategy means that the communication device selects the pre-synchronized SSB candidate set with the lowest power consumption or the pre-synchronized SSB candidate set with the smallest number of mode switching times.

Among them, the selection strategy can be determined according to the following conditions: if the working state of the communication device is a low power consumption state, such as in scenarios such as off-screen, insufficient power, and high temperature, the communication device selects the pre-synchronized SSB candidate set with the lowest power consumption ; If the working state of the communication device is a non-low power consumption state, such as in scenarios such as high-speed movement, the communication device selects the pre-synchronization SSB candidate set with the smallest number of mode switching times. If the signal quality of the communication device is good, that is, the signal quality of the communication device is greater than the first threshold, the communication device selects the pre-synchronization SSB candidate set with the lowest power consumption; if the signal quality of the communication device is poor, that is, the signal quality of the communication device is lower than the first threshold. two thresholds, the communication device selects the pre-synchronization SSB candidate set with the minimum number of mode switching times.

In the embodiment of the present application, the communication device needs to determine the power consumption of each pre-synchronized SSB candidate set for windowing, and the communication device performs windowing mode switching during the process from receiving the SSB candidate set to completing the paging message reception frequency.

Here, the communication device may determine the frequency and/or voltage for windowing each pre-synchronization SSB at different time domain positions to obtain a power consumption curve. Furthermore, according to the power consumption curve, the power consumption for windowing each pre-synchronization SSB candidate set is determined.

Exemplarily, the power consumption curve corresponding to SSB1 (that is, the first pre-synchronization SSB candidate set) is shown as curve 61 in FIG. 7A . The power consumption curve corresponding to SSB2 (that is, the second pre-synchronization SSB candidate set) is shown as curve 62 in FIG. 7A . The power consumption curve corresponding to SSB3 (that is, the third pre-synchronization SSB candidate set) is shown as curve 63 in FIG. 7A . The communication device may respectively calculate the areas formed by the curve 61 , the curve 62 , and the curve 63 and the time-domain axis to obtain the power consumption corresponding to the three pre-synchronization SSB candidate sets. In addition, it can be seen from the

curves

61, 62 and 63 that the communication device performs windowing on each pre-synchronized SSB candidate set until it finishes receiving paging messages, and the number of mode switching times is two times.

Step 705, the communication device selects a pre-synchronization SSB candidate set according to a selection strategy.

It can be understood that the communication device can dynamically select an optimal pre-synchronization SSB candidate set after comparing the power consumption of windowing the pre-synchronization SSB candidate set and comparing the number of mode switching times. For example, when the selection strategy is to select the pre-synchronization SSB candidate set with the lowest power consumption, and windowing SSB1 has the lowest power consumption, then the communication device may select SSB1 for pre-synchronization. In this way, the communication device can perform pre-synchronization after receiving SSB1, and after the pre-synchronization is completed, it will remain in the active mode until the paging message is received and enter the deep sleep mode.

Step 706, the communication device judges whether to perform neighbor cell measurement.

Here, if the communication device needs to perform neighbor cell measurement, then execute step 707, and if it does not need to perform neighbor cell measurement, then execute step 710.

Step 707, the communication device determines a plurality of neighboring cell measurement SSB candidate sets.

Here, the communication device may determine multiple neighboring cell measurement SSB candidate sets according to the time interval between the time domain position of the SSB after the MO and the time domain position of the MO.

Wherein, the communication device may select, from the SSBs after the MO, the time interval between the time domain position of the MO and the time domain position of the SSB that satisfies the selection condition according to the selection condition corresponding to the working mode, and obtain multiple neighboring cell measurement SSB candidate sets. If the communication device has N working modes, at most N pre-synchronization SSB candidate sets can be determined.

Exemplarily, the communication device may include three working modes: active mode, light sleep mode, and deep sleep mode. The communication device may determine selection conditions respectively corresponding to the three working modes, and determine the neighboring cell measurement SSB candidate set based on the three selection conditions.

In this embodiment of the present application, the fourth selection condition corresponding to the activation mode may be that the time interval between the time domain position of the MO and the time domain position of the SSB is smaller than the first threshold. The fifth selection condition corresponding to the light sleep mode may be that the time interval between the time domain position of the MO and the time domain position of the SSB is greater than or equal to the first threshold and less than the second threshold. The sixth selection condition corresponding to the deep sleep mode may be that the time interval between the time domain position of the MO and the time domain position of the SSB is greater than or equal to the first threshold.

Referring to FIG. 7B , SSB4 is located behind the time domain position of MO, and the time interval between the time domain position of MO and the time domain position of SSB4 is less than the first threshold, satisfying the above fourth selection condition. The communication device may select SSB4 as the first neighboring cell measurement SSB candidate set. Wherein, after the paging message is successfully received, the communication device may remain in the active mode until the SSB4 is received to perform neighbor cell measurement, and enter the deep sleep mode after the neighbor cell measurement is completed.

SSB5 is located behind the time domain position of MO, and the time interval between the time domain position of MO and the time domain position of SSB5 is greater than the first threshold and smaller than the second threshold, satisfying the above fifth selection condition. The communication device may select SSB5 as the second neighboring cell measurement SSB candidate set. Wherein, the communication device may enter the light sleep mode after receiving the paging message, and enter the active mode from the light sleep mode at the time domain position of SSB5, so as to receive SSB5 for neighbor cell measurement, and enter the deep sleep mode after the neighbor cell measurement is completed .

SSB6 is located behind the time domain position of MO, and the time interval between the time domain position of MO and the time domain position of SSB6 is greater than the second threshold, satisfying the sixth selection condition above. The communication device may select SSB6 as the third neighboring cell measurement SSB candidate set. Wherein, the communication device can enter the deep sleep mode after receiving the paging message until it wakes up before the time domain position of SSB6, and enters the active mode at the time domain position of SSB6 to receive SSB6 for neighbor cell measurement, neighbor cell measurement Go into deep sleep mode when done.

Step 708 , the communication device determines a selection strategy for selecting a neighboring cell measurement SSB candidate set according to the channel quality and working state.

Here, the communication device determines the selection strategy according to the channel quality and the working state, and the selection strategy means that the communication device selects the SSB candidate set for neighbor cell measurement with the lowest power consumption or the candidate set for neighbor cell measurement SSB with the smallest number of mode switching times.

Among them, the selection strategy can be determined by the following conditions: if the working state of the communication device is a low power consumption state, such as in the scene of off-screen, insufficient power, high temperature, etc., the communication device selects the pre-synchronized neighbor cell measurement with the lowest power consumption SSB candidate set; if the working state of the communication device is a non-low power consumption state, such as in scenarios such as high-speed movement, the communication device selects the SSB candidate set for pre-synchronization neighboring cell measurement with the smallest number of mode switching. If the signal quality of the communication device is good, that is, the signal quality of the communication device is greater than the first threshold, the communication device selects the pre-synchronization adjacent cell measurement SSB candidate set with the lowest power consumption; if the signal quality of the communication device is poor, that is, the signal quality of the communication device If the quality is less than the second threshold, the communication device selects the SSB candidate set for pre-synchronization neighboring cell measurement with the smallest number of mode switching times.

In the embodiment of the present application, the communication device needs to determine the frequency and/or voltage for windowing the measured SSB of each neighboring cell at different time domain positions to obtain the power consumption curve. Furthermore, according to the power consumption curve, the amount of power consumption for windowing the measurement SSB candidate set of each neighboring cell is determined.

Exemplarily, the power consumption curve corresponding to SSB4 (that is, the first neighboring cell measurement SSB candidate set) is shown as curve 64 in FIG. 7B . The power consumption curve corresponding to SSB5 (that is, the second neighboring cell measurement SSB candidate set) is shown as curve 65 in FIG. 7B . The power consumption curve corresponding to SSB6 (that is, the third neighboring cell measurement SSB candidate set) is shown as curve 66 in FIG. 7B .

The communication device can respectively calculate the area formed by the curve 64, the curve 65 and the curve 66 and the time domain axis, and obtain the power consumption corresponding to the above three neighboring cell measurement SSB candidate sets. In addition, it can be seen from the trends of curve 64, curve 65 and curve 66 that the communication device performs windowing on each neighboring cell measurement SSB candidate set until it finishes receiving paging messages, and the number of mode switching times is two.

Step 709, the communication device selects a pre-synchronization SSB candidate set according to a selection policy.

It can be understood that the communication device can dynamically select an optimal neighbor cell measurement SSB candidate set by comparing the power consumption of windowing the neighbor cell measurement SSB candidate set and comparing the number of mode switching times. For example, when the selection strategy is to select the SSB candidate set for neighbor cell measurement with the lowest power consumption, and SSB4 corresponds to the lowest power consumption, the communication device may select SSB4 as the SSB candidate set for neighbor cell measurement. In this way, the communication device can perform neighbor cell measurement after receiving SSB4, and after the neighbor cell measurement is completed, it remains in the active mode until it enters the deep sleep mode after receiving the paging message.

Step 710, the communication device performs pre-synchronization and/or neighbor cell measurement based on the selected pre-synchronization SSB candidate set, or the selected pre-synchronization SSB candidate set and neighboring cell measurement SSB candidate set.

It can be seen that in the embodiment of the present application, the communication device can determine the power consumption and the number of mode switching times for windowing each SSB candidate set; The SSB candidate set with a small number of mode switching times, and then the communication device can receive the selected SSB candidate set, and perform pre-synchronization or neighbor cell measurement according to the received SSB. That is to say, the communication device can dynamically select an appropriate SSB candidate set according to the power consumption of multiple SSB candidate sets, and perform power consumption control based on the selected appropriate SSB candidate set, thereby reducing the power consumption of the communication device and prolonging the communication period. The standby time of the device, or the performance of the communication device is ensured based on the selection of an appropriate SSB candidate set, and the implementation complexity is reduced.

In addition, the device can be used as a communication device, or a chip (such as a modem (Modem), a system on chip (system on chip), etc.) used for power consumption control in the communication device.
