It should be understood that the technical solution of the embodiment of the present application may be applied to a New Radio (NR) system or a future communication system, and may also be applied to other various wireless communication systems, for example: a narrowband Band-Internet of Things (NB-IoT) System, a Global System for Mobile communications (GSM), an Enhanced Data rate for GSM Evolution (EDGE) System, a Wideband Code Division Multiple Access (WCDMA) System, a Code Division Multiple Access (Code Division Multiple Access) 2000 System, a Time Division-synchronous Code Division Multiple Access (CDMA 2000) System, a Time Division-synchronous Code Division Multiple Access (TD-SCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, a Frequency Division Duplex (FDD) System, an LTE (TDD-Duplex), a UMTS-Universal Mobile telecommunications System, and the like.

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 state to which the method for receiving an SSB provided by the present application may be applied, and the method provided by 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 (C-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 (e.g., 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 (e.g., a continuous monitoring time C-DRX on-duration) 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 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 based on a handover requirement. That is, the terminal device needs to window to receive the pre-synchronization SSB before paging the listening occasion or continuing the listening occasion to complete the pre-synchronization with the network device. In addition, the terminal device may also perform windowing to receive the neighbor cell measurement SSB when there is a handover requirement, so as to implement the neighbor cell measurement.

Referring to fig. 3, a flow chart of a method for receiving SSB in related art is shown. Specifically, the SSB receiving method in the related art may include the steps of:

and step 301, entering a 5G standby mode.

Step 302, determining the time domain position of Paging Frame (PF)/Paging location (PO) Paging listening opportunity (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.

And step 303, determining the receiving number of the pre-synchronization SSBs according to the time domain position of the PO/PF/MO.

In the related art, the terminal device may determine a preset number (e.g., one or two) of SSBs for pre-synchronization according to the time domain location of the PO/PF/MO. For ease of description, the present application will next refer to the SSBs determined for pre-synchronization as pre-synchronization SSBs. The pre-synchronization SSB is configured to implement pre-synchronization between the terminal device and the network device, and specifically, the terminal device may perform operations such as Automatic Gain Control (AGC) or Automatic Frequency Control (AFC) according to the pre-synchronization SSB.

Step 304, selecting the pre-synchronization SSB according to the receiving number of the pre-synchronization SSB.

Here, the terminal device may determine the pre-synchronization SSBs satisfying the reception number according to the determined reception number of the pre-synchronization SSBs.

Step 305, judging whether to perform neighbor measurement.

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

And step 306, determining the receiving quantity of the neighbor cell measurement SSB according to the time domain position of the PO/PF/MO.

Here, in the case that the neighbor cell measurement needs to be performed, the terminal device needs to determine the SSB for the neighbor cell measurement after PO/PF/MO. For convenience of description, the present application will hereinafter refer to determining SSBs for neighbor measurement as neighbor measurement SSBs. Illustratively, the terminal device may select a preset number of neighbor cell measurement SSBs according to the time domain position of the PO/PF/MO.

Step 307, selecting the neighbor measurement SSB based on the received number of the neighbor measurement SSBs.

Here, the terminal device may determine, according to the determined number of received neighbor cell measurements SSBs, neighbor cell measurements SSBs that satisfy the number of received neighbor cell measurements SSBs.

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

After determining the pre-synchronization SSB and/or the neighbor measurement SSB, the terminal device may determine, according to a position relationship between the time domain position of the PF/PO/MO and the time domain position of the determined SSB (which may be the pre-synchronization SSB or the neighbor measurement SSB), a frequency and/or a voltage of the terminal device at different time domain positions, and the terminal device may have a plurality of operation modes, for example, a deep sleep mode, a light sleep mode, an activation mode, and the like, corresponding to a change in the frequency and/or the voltage. In turn, the terminal device may receive its determined SSB at the determined frequency and/or voltage magnitudes at different time domain locations. Then, the terminal device may perform pre-synchronization and/or neighbor cell measurement based on the received SSB.

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 related art shown in fig. 4A, the terminal device may select two SSBs located before the PF as pre-synchronization SSBs.

Wherein the terminal device may wake up from the deep sleep mode before the time domain location of the first pre-synchronization SSB arrives, may be in the active mode when the first pre-synchronization SSB (SSB 1 in the illustration) arrives, and may receive the first pre-synchronization SSB (SSB 2 in the illustration) in the active mode. Since the two pre-synchronization SSBs (SSBs 1, SSB2 in the illustration) in fig. 4A are closely spaced in time domain, the terminal device can enter the doze mode immediately after receiving the first pre-synchronization SSB (SSB 1 in the illustration). It can be understood that, in the doze mode, the terminal device may adjust the frequency and/or voltage of the chip to turn off part of the monitoring function, so as to save the power consumption of the terminal device. When the start time of the time domain position of the second pre-synchronization SSB (SSB 2 in the illustration) arrives, the terminal device may immediately enter the active mode from the doze mode, in which it receives the second pre-synchronization SSB. 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 a pre-synchronization SSB (SSB 1 'in the figure), a first SSB (SSB 2' in the figure) after the SSB for pre-synchronization may be used as the neighbor cell measurement SSB.

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 pre-synchronization SSBs and/or the neighbor measurement SSBs) by using a preset SSB number (for example, one or two), and further, the terminal device divides different operation modes for the terminal device according to a position relationship between a time domain position of the SSBs and a time domain position of the PO/PF/MO. Therefore, the terminal equipment can adjust the frequency and/or voltage in different working modes through the DVFS technology, and the purpose of saving energy is achieved.

However, in the method for selecting an SSB in the related art, the terminal device selects a corresponding SSB according to the preset number of SSBs, and further receives the SSBs to perform presynchronization or neighbor cell measurement. However, since the receiving number of SSBs determined by the terminal device is fixed, it may happen that the terminal device receives the selected SSBs in some states (e.g., the selected number of SSBs is greater than the required number of SSBs) which may result in wasted power consumption, and the terminal device cannot receive the selected SSBs in some states (e.g., the selected number of SSBs is less than the required number of SSBs). Therefore, how to compromise the power consumption and the performance of the 5G terminal equipment is very important.

Based on this, the embodiments of the present application provide a method for receiving an SSB, which may be applied in a communication device. The communication device may be implemented by software or hardware, and the communication device may be integrated in the terminal device shown in fig. 1 in the embodiment of the present application.

Specifically, according to the SSB receiving method provided in the embodiment of the present application, the communication device may determine the receiving number of SSBs according to the channel quality and the operating state; receiving SSBs based on the received number. That is, the communication apparatus may acquire the current channel quality and operating state, dynamically determine the number of SSBs matching the channel quality and operating state, and further receive the SSBs corresponding to the number of SSBs. Therefore, the receiving quantity of the SSBs determined by the communication device meets the requirements of the current channel quality and the working state, and the power consumption and the performance of the communication device can be considered.

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.

Fig. 5 is a flowchart illustrating a first method for receiving an SSB according to an embodiment of the present application, and referring to fig. 5, in an embodiment of the present application, a method for a communication device to receive an SSB may include the following steps.

Step 110, determining the receiving number of the SSBs according to the channel quality and the operating state.

Step 120, receiving the SSBs based on the received number.

It should be understood that SSBs are information broadcast by a network device and that the reception of SSBs depends on the broadcast channel between the network device and the communication device.

The channel quality referred to in the embodiments of the present application refers to the channel quality of a broadcast channel between a network device and a communication device. Illustratively, the channel quality may include at least one of reference signal received power, reference signal received quality, path loss, signal to interference plus noise ratio. The embodiment of the present application does not limit this. Correspondingly, the receiving number of the SSBs is determined according to the channel quality, which can also be understood as determining the receiving number of the SSBs according to the value of at least one of the above physical quantities characterizing the channel quality.

It should be noted that, in the embodiment of the present application, the comparison of the channel quality may also be understood as a comparison of values of a physical quantity used for characterizing the channel quality, for example, the channel quality is higher (better, etc.), and the signal to interference plus noise ratio is understood to be greater than the signal to interference plus noise ratio threshold. The embodiment of the present application is not described in detail herein.

In the embodiment of the application, the communication device may measure the channel condition of the broadcast channel between the network device and the network device to obtain the channel quality of the broadcast channel.

Generally, when the channel quality is better, the SSBs can be completely received, and at this time, the communication device only needs to receive fewer SSBs to complete the pre-synchronization or the neighbor cell measurement. However, when the channel quality is poor, the SSBs may have incomplete reception or missed reception, and therefore, in this scenario, the communication device needs to receive multiple SSBs, so that the communication device can completely receive the SSBs, and the transmission performance is ensured.

Based on this, in the embodiment of the present application, the communication apparatus may measure the channel quality of the broadcast information transmitting the SSBs, and determine the number of SSBs satisfying the current channel quality.

It should be noted that the number of SSBs satisfying the channel quality may be multiple. For example, when the channel quality is good, the communication device only needs to receive one or more SSBs to meet the performance requirement corresponding to the channel quality. Therefore, when the channel quality is good, the number of SSBs satisfying the channel quality may be one, two, three, or the like. When the channel quality is poor, the communication apparatus needs to receive more than three SSBs to meet the performance requirement, and therefore, when the channel quality is poor, the number of SSBs meeting the channel quality may be three, four, five, and the like.

In an embodiment of the present application, a communication apparatus may determine a plurality of candidate numbers satisfying a current channel quality based on the channel quality. Further, the communication apparatus may select one from the plurality of candidate numbers as the final reception number of SSBs according to the current operation state.

Here, the operation state may be a state in which power consumption control is performed on the communication apparatus, and includes a low power consumption operation state and a non-low power consumption operation state.

It is to be understood that, when the operation state of the communication apparatus is the low power consumption operation state, which indicates that the current communication apparatus needs to perform power consumption control to avoid waste of power consumption, the communication apparatus may select a smaller reception number as the final SSB from the plurality of candidate numbers. When the operating state of the communication apparatus is a non-low power consumption operating state, it means that the communication apparatus does not need to perform power consumption control at present, but needs to preferentially ensure the performance of the communication apparatus, and at this time, the communication apparatus may select a larger one from a plurality of candidate numbers as the final reception number of SSBs.

In some embodiments, the SSB may be a pre-synchronization SSB, where the pre-synchronization SSB is used for pre-synchronization, that is, pre-synchronization between the communication apparatus and the network device is achieved; the SSB may also be a neighbor measurement SSB; the neighbor cell measurement SSB is used for neighbor cell measurement, and measurement of the communication apparatus on the neighbor cell is realized. The embodiments of the present application do not limit the type of SSB.

It is understood that, in the embodiment of the present application, the communication apparatus may determine the reception number of the SSBs according to the channel quality and the operating state; receiving SSBs based on the received number. That is, the communication apparatus may acquire the current channel quality and operating state, dynamically determine the number of SSBs matching the channel quality and operating state, and further receive the SSBs corresponding to the number of SSBs. Therefore, the receiving quantity of the SSBs determined by the communication device meets the requirements of the current channel quality and the working state, and the effect of considering both the power consumption and the performance can be realized.

How the communication apparatus determines the reception number of SSBs according to the channel quality and the operation state is described in detail below.

In one possible implementation manner, the determining the receiving number of SSBs according to the channel quality and the operating state in step 110 may be implemented by:

step 1101, determining a plurality of candidate quantities according to the channel quality;

step 1102, determining the number of SSBs received from the plurality of candidate numbers according to the operating state.

In some embodiments, the communication device may determine a number of candidates that meet the performance requirements of the communication device based on the quality of the channel. For example, when the channel quality is good, the communication device receives SSBs 1 and above, and can complete the pre-synchronization or neighbor cell measurement successfully. Therefore, the number of the communication devices SSB only needs to satisfy 1 or more. Based on this, the communication device can determine a plurality of candidate numbers. Such as the candidate number 1 (i.e., 1 SSB), the candidate number 2 (i.e., 2 SSBs), or the candidate number 3 (i.e., 3 SSBs), etc., which can be used as the number of SSBs received by the communication apparatus.

When the channel quality is general, the communication apparatus may not receive the SSBs when selecting 1 SSB, and thus the communication apparatus needs to select a plurality of SSBs (for example, more than 2 SSBs) to complete the reception of the SSBs. Therefore, the number of the communication devices SSB needs to be 2 or more. The communication device may then determine a plurality of candidate numbers. Such as the candidate number 2 (i.e., 2 SSBs), the candidate number 3 (i.e., 3 SSBs), or the candidate number 4 (i.e., 4 SSBs), etc., which can be used as the number of SSBs received by the communication apparatus.

When the channel quality is poor, the communication apparatus selects 1 or 2 SSBs, which may result in that the communication apparatus cannot receive the SSBs, and thus the communication apparatus needs to select more SSBs (for example, more than 3 SSBs) to complete the reception of the SSBs. Therefore, the number of SSBs of the communication device needs to be 3 or more. The communication device may then determine a plurality of candidate numbers. Such as the candidate number 3 (i.e., 3 SSBs), the candidate number 4 (i.e., 4 SSBs), or the candidate number 5 (i.e., 5 SSBs), etc., which can be used as the number of SSBs received by the communication apparatus.

It can be understood that, in the embodiment of the present application, after determining a plurality of candidate quantities based on the channel quality, the communication apparatus may determine, according to the operating state of the current communication apparatus, a received quantity of SSBs from the plurality of candidate quantities, and finally receive SSBs corresponding to the received quantity of SSBs to perform pre-synchronization or neighbor cell measurement. Thus, by dynamically determining the number of SSBs received based on the channel quality and operating state of the communication device, both power consumption and performance of the communication device can be taken into account.

How the communication apparatus determines the candidate number based on the channel quality is described in detail below.

In one possible implementation manner, the determining the plurality of candidate numbers according to the channel quality in step 1101 may be implemented by:

determining the quantity corresponding to each of the receiving capacity grades based on the channel quality to obtain a plurality of candidate quantities; wherein the plurality of reception capability levels comprise:

a first capability level with power consumption first;

a second level of capability for power consumption performance equalization;

a third level of capability with performance priority.

That is, different reception levels may be classified according to demands for power consumption and performance. At the first capability level where power consumption is prioritized, the communication apparatus expects reduction of power consumption, and therefore the communication apparatus expects a smaller number of SSBs received at that level. At the third capability level with priority on performance, the communication device expects to be able to receive SSBs quickly to implement pre-synchronization or neighbor measurement functions, so at this level the communication device expects a larger number of SSBs to be received. At the second capability level with balanced power consumption performance, the communication device has low requirements for high performance and low power consumption, or the communication device has high requirements for high performance and low power consumption, and at this time, the communication device expects a relatively moderate reception number of SSBs.

Based on this, the communication apparatus can configure the number required for the above three reception capability levels for each channel quality. Illustratively, table 1 shows the number of SSBs corresponding to each of the plurality of capability levels. As shown in table 1 below, the abscissa represents the number of SSBs corresponding to the capability level, and the ordinate represents the quality of the channel.

TABLE 1 number of SSBs corresponding to each of a plurality of capability levels

As can be seen from table 1, when the channel quality is greater than or equal to the first threshold, that is, the channel quality is better, the number of SSBs corresponding to the first capability level is 1, the number of SSBs corresponding to the second capability level is 2, and the number of SSBs corresponding to the third capability level is 3. When the channel quality is less than the second threshold, that is, the channel quality is poor, the number of SSBs corresponding to the first capability level may be 3, the number of SSBs corresponding to the second capability level is 4, and the number of SSBs corresponding to the third capability level is 5.

It is understood that, after determining the current channel quality, the communication apparatus may determine the number corresponding to each of the three receiving capability levels according to the channel quality, so as to obtain a plurality of candidate numbers.

That is, in the embodiment of the present application, the communication apparatus may determine, based on the channel quality, the number of SSBs corresponding to each of the plurality of reception capability levels, and obtain a plurality of candidate numbers based on the number of SSBs. And further determining the receiving number of the SSBs from a plurality of candidate numbers according to the working state of the current communication device, and finally receiving the SSBs corresponding to the receiving number of the SSBs to execute pre-synchronization or neighbor cell measurement. Thus, the receiving number of the SSBs can be dynamically determined according to the channel quality and the working state of the communication device, and the effect of considering both power consumption and performance is achieved.

The following describes in detail how the operating state of the communication device is determined.

In the embodiment of the present application, the operating state may include a low power consumption operating state and a non-low power consumption operating state.

In an embodiment of the present application, the communication apparatus may determine that the communication apparatus enters the low power consumption operating state when at least one of the following conditions is satisfied:

the operating frequency of the communication device is less than a preset frequency threshold;

the position change rate of the communication device is smaller than a preset change threshold value;

the electric quantity of the communication device is smaller than a preset electric quantity threshold value;

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

the screen state of the communication device is a screen-off state;

the communication device receives a switching instruction; the switching instruction is used for starting the low power consumption mode.

It can be understood that when the operating frequency of the communication device is less than the preset frequency threshold, the communication device may be considered to be not frequently operated by the user, and in this scenario, the application or operation with higher power consumption may be turned off, and the low power consumption mode is entered. Here, the operation frequency may be an operation frequency for a screen, or an operation frequency for a certain type of application (e.g., a call application or a video application).

The rate of change of the position of the communication device is less than the preset change threshold, and it can be considered that the communication device is not moving at a high speed currently, and the demand on performance is low. Therefore, a low power consumption mode may be entered for power saving in this scenario.

The power of the communication device is less than the preset power threshold, that is, the power of the communication device is low, and power saving is required. At this time, the communication apparatus may enter a low power consumption operation state. For example, the preset charge threshold may be set to 10%, and is not limited herein.

In addition, when the screen state of the communication device is the screen state, it can be determined that the user does not have a high demand for the data service currently, and at this time, the communication device can enter a low-power-consumption working state to save power.

In an embodiment of the present application, the communication apparatus may determine that the communication apparatus enters the non-power consumption operating state when at least one of the following conditions is satisfied:

the operating frequency of the communication device is greater than or equal to a preset frequency threshold;

the position change rate of the communication device is greater than or equal to a preset change threshold;

the electric quantity of the communication device is greater than or equal to a preset electric quantity threshold value;

the temperature of the communication device is lower than a preset temperature threshold;

the screen state of the communication device is a bright screen state;

the communication device receives a switching instruction; the switching instruction is used to initiate a non-low power mode.

It is understood that when the operating frequency of the communication apparatus is greater than or equal to the preset frequency threshold, it may be considered that the operation of the communication apparatus by the current user is frequent, and under this condition, the communication apparatus enters a non-low power consumption operating state, which needs to meet the user's requirement with priority, so as to give priority to performance.

The position change rate of the communication device is greater than or equal to the preset change threshold, and it can be considered that the communication device is currently moving at a high speed and has a high performance requirement. Therefore, the non-low power consumption mode can be entered in the scene, and the performance requirement of the user on the communication device is met preferentially.

The electric quantity of the communication device is smaller than the preset electric quantity threshold value, that is, the electric quantity of the communication device is higher, and power saving is not needed. At this time, the communication apparatus may enter a non-low power consumption operation state. For example, the preset charge threshold may be set to 10%, and is not limited herein.

In addition, when the screen state of the communication device is a bright screen state, it can be determined that the current demand of the user for the data service is high, and at this time, the communication device can enter a non-low power consumption working state to give priority to performance.

It follows that different operating states have different requirements on power consumption and performance. Therefore, the communication device can select the candidate number matching the requirement according to the current working state as the final receiving number of the SSBs.

In the embodiment of the present application, the communication apparatus determines the SSB reception number based on the channel quality and the operation state. The communication device may determine the SSB reception numbers corresponding to the plurality of reception capability levels, respectively, based on the channel quality, and obtain a plurality of candidate SSB numbers based on the SSB reception numbers. Further according to the working state (namely, the low-power-consumption working state or the non-low-power-consumption working state) of the current communication device, the SSB receiving quantity is determined from the multiple candidate SSB receiving quantities, and finally the SSB corresponding to the SSB quantity is received to execute presynchronization or neighbor cell measurement. Thus, the SSB receiving quantity can be dynamically determined according to the channel quality and the working state of the communication device, and the effect of considering both power consumption and performance is achieved.

In some embodiments, the communication apparatus may select at least one SSB matching the reception number from the plurality of SSBs based on time intervals between time domain positions of the plurality of SSBs and time domain positions of the listening opportunity, respectively, to obtain the target SSB. Wherein the listening occasion includes a paging listening occasion and/or a persistent listening occasion. For example, the listening occasion may be a time domain location of the PO/PF/MO.

Here, the plurality of SSBs refers to SSBs configured by the network device. It is understood that, after the communication apparatus selects the final number of SSBs from the candidate numbers, at least one SSB matching the number of SSBs can be selected from the SSBs configured by the network device according to the determined number of SSBs to obtain the target SSB.

In one possible implementation, the communication device may select the SSBs that are closest to the listening opportunity time domain location and match the number of SSBs received for reception.

For example, when the communication apparatus determines that the number of SSBs received is two, two SSBs closest to the time domain position of the listening opportunity may be selected for reception.

In another possible implementation manner, the communication apparatus may further calculate a time interval between the time domain position of the SSB and the time domain position of the listening opportunity, and select the SSB matching the reception number of the SSB according to an operation mode of the communication device in the time interval.

In an embodiment of the present application, referring to the flowchart shown in fig. 6, a method for receiving an SSB provided in the embodiment of the present application may include the following steps:

step 601: the communication device enters a 5G standby mode.

Step 602: the communication device determines the MO location.

Step 603: the communication device determines the number of candidates for pre-synchronization SSB based on the channel quality.

Here, the communication apparatus may measure the channel quality of the broadcast channel transmitting the SSB, and determine the current channel quality.

Further, the communication device determines a first candidate number corresponding to a first power consumption priority level, a second candidate number corresponding to a second power consumption performance balance level, and a third candidate number corresponding to a third power performance priority level based on the channel quality.

Step 604: the communication device obtains the receiving number of the pre-synchronization SSBs from the candidate number according to the operation state.

Here, the operation state of the communication apparatus includes: a low power consumption working state and a non-low power consumption working state.

It is understood that the communication apparatus determines the number of pre-synchronization SSB receptions from the first candidate number, the second candidate number, and the third candidate number determined in step 603 according to the operation state.

For example, if the current operating state of the communication apparatus is a low power consumption operating state, the first candidate number corresponding to the first capability with priority on power consumption may be selected. If the current operating state of the communication apparatus is a non-low power consumption operating state, the third candidate number corresponding to the third capability with a priority in performance may be selected as the pre-synchronization SSB reception number.

Step 605: the communication device pre-synchronizes the SSB reception candidate number, and determines a pre-synchronized SSB location matching the pre-synchronized SSB reception number.

Step 606: the communication device judges whether to perform neighbor measurement.

Here, if the communication apparatus needs to perform the neighbor cell measurement, step 607 is executed; if the communication apparatus does not perform the neighbor cell measurement, step 610 is performed.

Step 607: the communication device determines the candidate number for neighbor measurement SSB according to the channel quality.

Specifically, the communication device determines a first candidate number corresponding to a first power consumption priority level, a second candidate number corresponding to a second power consumption performance balance level, and a third candidate number corresponding to a third power performance priority level based on the channel quality.

Step 608: and the communication device obtains the receiving number of the neighbor cell measurement SSB from the candidate number according to the working state.

It is understood that the communication apparatus determines the number of received neighbor cell measurement SSBs from the first candidate number, the second candidate number, and the third candidate number determined in step 603 according to the operating state.

For example, if the current operating state of the communication apparatus is a low power consumption operating state, a first candidate number corresponding to a first capability with a priority on power consumption may be selected as the neighboring cell measurement SSB reception number. If the current operating state of the communication apparatus is a non-low power consumption operating state, the third candidate number corresponding to the third capability with a priority in performance may be selected as the neighboring cell measurement SSB reception number.

Step 609: the communication device receives the candidate number of the neighbor measurement SSB, and determines the position of the neighbor measurement SSB matched with the received number of the neighbor measurement SSB.

Step 610, the communication device receives the SSB based on the pre-synchronized SSB location, or the pre-synchronized SSB location and the neighbor measurement SSB location.

As can be seen, in the embodiment of the present application, the communication apparatus determines the reception number of SSBs based on the channel quality and the operating state. Specifically, the communication apparatus may determine the numbers respectively corresponding to the plurality of reception capability levels based on the channel quality, and derive the plurality of candidate numbers based thereon. Further, according to the operating state (i.e. low power consumption operating state or non-low power consumption operating state) of the current communication apparatus, the receiving number of the SSBs is determined from the plurality of candidate numbers, and finally the SSBs corresponding to the receiving number of the SSBs are received to perform pre-synchronization or neighbor cell measurement. Thus, the receiving number of the SSBs is dynamically determined according to the channel quality and the operating state of the communication device, and the power consumption and the performance of the communication device can be considered.
