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: narrowband internet of things (NB-IoT) systems, global system for mobile communications (Global System of Mobile communication, GSM), enhanced data rates for GSM evolution (ENHANCED DATA RATE for GSM Evolution, EDGE) systems, wideband code Division multiple access (Wideband Code Division Multiple Access, WCDMA) systems, code Division multiple access 2000 (Code Division Multiple Access, CDMA 2000) systems, time Division multiple access (Time Division-Synchronization Code Division Multiple Access, TD-SCDMA) systems, general packet Radio Service (GENERAL PACKET Radio Service, GPRS), long term evolution (Long Term Evolution, LTE) systems, LTE frequency Division duplex (Frequency Division Duplex, FDD) systems, LTE Time Division duplex (Time Division Duplex, TDD), universal mobile telecommunication system (Universal Mobile Telecommunication System, UMTS), and the like.

Fig. 1 shows a network architecture to which embodiments of the present application may be applied. As shown in fig. 1, the network architecture provided in this embodiment includes: a network device 101 and a terminal device 102. The terminal device according to the embodiment 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 DEVICE) or Mobile Stations (MSs) and the like. The network device according to the embodiment of the application is a device deployed in a radio access network to provide a wireless communication function for a terminal device. In the embodiment of the present application, the network device may be, for example, a base station shown in fig. 1, where the base station may include various types 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 SSB provided by the present application may be applicable, and the method provided by the embodiment of the present application may be applied to a discontinuous reception (Discontinuous Reception, DRX) mechanism of a terminal device. Specifically, the method provided by the embodiment of the application can be applied to an idle state DRX (discontinuous DRX) mechanism and a Connected state DRX (C-DRX) mechanism.

Wherein the idle DRX mechanism is the paging mechanism. Fig. 2 shows one DRX cycle in which a terminal device in an idle state listens to a physical downlink control channel (Physical Downlink Control Channel, PDCCH) only for a specific period of time (e.g., paging listening occasion) to receive paging messages. And at other times the listening function may be turned off without listening to the PDCCH.

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

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

In practical applications, the terminal device needs to pre-synchronize with the network device before the paging listening occasion or the continuous listening occasion, and the terminal device also needs to perform neighbor cell measurement based on the handover requirement. That is, the terminal device needs to window to receive the pre-synchronization SSB before the paging listening occasion or the continuous listening occasion to complete the pre-synchronization with the network device. In addition, when the terminal equipment has a switching requirement, windowing is performed to receive the neighbor cell measurement SSB so as to realize neighbor cell measurement.

Referring to fig. 3, a flowchart of a related art SSB reception method is shown. Specifically, the related art SSB reception method may include the steps of:

step 301, entering a 5G standby mode.

Step 302, determining a time domain position of paging frame (PAGING FRAME, PF)/paging position (Paging Occasion, PO)/paging listening occasion (Monitoring Occasion, MO).

Here, the terminal device may determine the time domain location 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 location of the MO according to the beam where it is currently located.

Step 303, determining the number of received 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 (for example, one or two) SSBs for presynchronization according to the time domain position of the PO/PF/MO. For ease of description, the present application will hereinafter refer to SSBs determined for presynchronization as presynchronized SSBs. Wherein the pre-synchronization SSB is used for implementing pre-synchronization between the terminal device and the network device, specifically, the terminal device may perform operations such as automatic gain control (Automatic Gain Control, AGC), or automatic frequency control (Automatic Frequency Control, AFC) according to the pre-synchronization SSB.

Step 304, selecting a presynchronized SSB according to the received number of presynchronized SSBs.

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

Step 305, determining whether to perform neighbor cell measurement.

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

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 case neighbor measurements need to be made, the terminal device also needs to determine SSB for neighbor measurements after PO/PF/MO. For convenience of description, the present application will hereinafter refer to SSB determined for neighbor measurement as neighbor measurement SSB. For example, the terminal device may select a preset number of neighbor measurement SSBs according to the time domain location 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 the neighbor measurement SSB satisfying the reception number according to the determined reception number of the neighbor measurement SSB.

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

After determining the presynchronized SSB and/or the neighbor measurement SSB, the terminal device may determine the frequency and/or voltage of the terminal device at different time domain positions according to the position relationship between the time domain position of the PF/PO/MO and the determined time domain position of the SSB (may be the presynchronized SSB or the neighbor measurement SSB), and may have multiple operation modes, such as a deep sleep mode, a shallow sleep mode, an active mode, and the like, corresponding to the change of the frequency and/or voltage. Furthermore, the terminal device may receive its determined SSB in accordance with the determined frequency and/or voltage magnitudes at the different time domain locations. The terminal device may then perform pre-synchronization and/or neighbor measurements based on the received SSB.

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

Wherein the terminal device may wake up from a deep sleep mode before the time domain position of the first presynchronized SSB arrives, may be in an active mode when the first presynchronized SSB (SSB 1 in the illustration) arrives, and may receive the first presynchronized SSB (SSB 2 in the illustration) in the active mode. Since the time domain locations of the two pre-synchronized SSBs (SSB 1, SSB2 in the illustration) in fig. 4A are closely spaced, the terminal device can enter the shallow sleep mode immediately after receiving the first pre-synchronized SSB (SSB 1 in the illustration). It can be understood that in the shallow sleep mode, the terminal device can adjust the frequency and/or voltage of the chip to turn off part of the monitoring function, thereby saving the power consumption of the terminal device. When the start time of the time domain position of the second presynchronized SSB (SSB 2 in the illustration) arrives, the terminal device can immediately enter an active mode from the shallow sleep mode, in which the second presynchronized SSB is received. After the terminal device receives the second presynchronization SSB, it can enter the shallow sleep 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 shallow sleep mode to monitor the paging message, and after the PO in the PF ends, 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 device turns off the monitoring function with the lowest power consumption.

For example, in a scenario where the terminal device needs to perform 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 the presynchronized SSB (SSB 1 'in the drawing), the first SSB (SSB 2' in the drawing) located after the presynchronized SSB may be used as the neighbor cell measurement SSB.

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

As can be seen from the above examples, the terminal device in the related art determines the SSB (including presynchronizing SSB and/or neighbor measurement SSB) by means of a preset number of SSBs (for example, one or two), and further, the terminal device divides different operation modes for the terminal device according to the position relationship between the time domain position of the SSB and the time domain position of the PO/PF/MO. In this way, the terminal device can adjust the frequency and/or the voltage under different working modes through DVFS technology, thereby achieving the purpose of energy saving.

However, in the method for selecting SSBs in the related art, the terminal device selects the corresponding SSB according to the preset number of SSBs, and further causes the terminal device to receive the SSB to perform presynchronization or neighbor measurement. However, since the number of SSBs received by the terminal device is fixed, it may happen that in some states, the terminal device receives the selected SSBs and consumes power (e.g., the number of SSBs selected is greater than the number of SSBs required), and in some states, the terminal device receives the selected SSBs and cannot meet the performance requirement (e.g., the number of SSBs selected is less than the number of SSBs required). Therefore, how to achieve both the power consumption and the performance of the 5G terminal device is important.

Based on this, the embodiment of the application provides a method for receiving SSB, which can be applied to a communication device. The communication device may be implemented in software or hardware, and the communication device may be integrated into the terminal device shown in fig. 1 according to the embodiment of the present application.

Specifically, according to the SSB receiving method provided by the embodiment of the present application, the communication device may determine the number of SSBs received according to the channel quality and the working state; SSBs are received based on the number of receptions. That is, the communication device may acquire the current channel quality and operation state, dynamically determine the number of SSBs matching the channel quality and operation state, and further receive SSBs corresponding to the number of SSBs. Thus, the number of SSBs received by the communication device is determined to meet the current channel quality and the requirements of the working state, so that both 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 accompanying drawings in the embodiments of the present application.

An embodiment of the present application provides a method for receiving SSB, and fig. 5 is a flowchart of the method for receiving SSB provided in the embodiment of the present application, and referring to fig. 5, in the embodiment of the present application, the method for receiving SSB by a communication device may include the following steps.

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

Step 120, receiving SSBs based on the number of receptions.

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

The channel quality mentioned in the embodiment of the application refers to the channel quality of the broadcast channel between the network device and the communication device. The channel quality may include at least one of reference signal received power, reference signal received quality, path loss, signal-to-interference-and-noise ratio, for example. The embodiment of the present application is not limited thereto. Accordingly, determining the number of SSBs according to the channel quality may be understood as determining the number of SSBs according to the value of at least one of the 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 be understood as a comparison of the values of the physical quantities used to characterize the channel quality, for example, that the channel quality is higher (better, etc.), and that the signal-to-interference-and-noise ratio is greater than the signal-to-interference-and-noise ratio threshold. The embodiments of the present application will not be described in detail.

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

Generally, when the channel quality is good, the SSB can be completely received, and at this time, the communication device only needs to receive less SSB to complete pre-synchronization or neighbor measurement. In this scenario, the communication device needs to receive multiple SSBs, so that the communication device can completely receive the SSBs, thereby ensuring transmission performance.

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

It should be noted that there may be a plurality of SSBs satisfying the channel quality. For example, when the channel quality is good, the communication device can meet the performance requirement corresponding to the channel quality only by receiving one or more than one SSB. Thus, 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 device needs to receive more than three SSBs to meet the performance requirement, so when the channel quality is poor, the number of SSBs meeting the channel quality can be three, four, five, etc.

In the embodiment of the application, the communication device can determine a plurality of candidate numbers meeting the current channel quality based on the channel quality. Further, the communication device may select one of the plurality of candidate numbers as the final SSB reception number 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, including a low power consumption operation state and a non-low power consumption operation state.

It will be appreciated that when the operating state of the communication device is a low power consumption operating state, it is indicated that the current communication device needs to perform power consumption control to avoid power consumption waste, and at this time, the communication device may select a smaller number of candidates as the final SSB reception number. When the operation state of the communication device is not the low power consumption operation state, it is indicated that the current communication device does not need to perform power consumption control, but needs to preferentially ensure the performance of the communication device, and at this time, the communication device may select a larger one from a plurality of candidate numbers as the final SSB reception number.

In some embodiments, the SSB may be a presynchronized SSB, where the presynchronized SSB is used for presynchronizing, i.e., implementing presynchronization between the communication device and the network equipment; the SSB may also measure SSB for a neighbor cell; the neighbor cell measurement SSB is used for neighbor cell measurement, and the measurement of the communication device on the neighbor cell is realized. The embodiment of the application does not limit the type of SSB.

It may be appreciated that in the embodiment of the present application, the communication device may determine the number of SSBs received according to the channel quality and the working state; SSBs are received based on the number of receptions. That is, the communication device may acquire the current channel quality and operation state, dynamically determine the number of SSBs matching the channel quality and operation state, and further receive SSBs corresponding to the number of SSBs. Thus, the number of SSB received by the communication device meets the current channel quality and the requirement of the working state, and the effect of taking the power consumption and the performance into consideration can be achieved.

How the communication device determines the number of SSBs received based on the channel quality and the operating state is described in detail below.

In one possible implementation, determining the 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 numbers according to the channel quality;

Step 1102, determining the number of SSB received from a plurality of candidate numbers according to the working 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 quality. Illustratively, when the channel quality is good, the communication device receives SSBs of 1 and above to successfully complete pre-synchronization or neighbor measurement. Therefore, the number of communication apparatuses SSB only needs to satisfy 1 or more. Based on this, the communication device can determine a plurality of candidate numbers. Such as number of candidates 1 (i.e., 1 SSB), number of candidates 2 (i.e., 2 SSBs), or number of candidates 3 (i.e., 3 SSBs), etc., which may all be the number of SSBs received by the communication device.

When the channel quality is generally equal to 1 SSB, the communication device may not receive the SSB, so that the communication device needs to select multiple SSBs (e.g., more than 2 SSBs) to complete the SSB reception. Therefore, the number of communication apparatuses SSB needs to satisfy 2 or more. Then the communication device may determine a number of candidates. Such as number of candidates 2 (i.e., 2 SSBs), number of candidates 3 (i.e., 3 SSBs), or number of candidates 4 (i.e., 4 SSBs), etc., which may all be the number of SSBs received by the communication device.

When the channel quality is poor, the communication device selects 1 or 2 SSBs, which may cause the communication device to fail to receive the SSBs, so that the communication device needs to select more SSBs (e.g., more than 3 SSBs) to complete the SSB reception. Therefore, the number of SSBs of the communication device needs to satisfy 3 or more. Then the communication device may determine a number of candidates. Such as number of candidates 3 (i.e., 3 SSBs), number of candidates 4 (i.e., 4 SSBs), or number of candidates 5 (i.e., 5 SSBs), etc., which may all be the number of SSBs received by the communication device.

It may be appreciated that in the embodiment of the present application, after determining a plurality of candidate numbers based on the channel quality, the communication device may determine, according to the current working state of the communication device, the number of SSBs received from the plurality of candidate numbers, and finally receive the SSB corresponding to the number of SSBs received to perform presynchronization or neighbor measurement. Thus, by dynamically determining the number of SSBs received according to the channel quality and the operating state of the communication apparatus, both power consumption and performance of the communication apparatus can be achieved.

How the communication device determines the number of candidates based on the channel quality is described in detail below.

In one possible implementation, determining the number of candidates according to the channel quality in step 1101 may be implemented by:

determining the number corresponding to each of the plurality of receiving capability levels based on the channel quality to obtain a plurality of candidate numbers; wherein the plurality of reception capability levels includes:

A first capability level at which power consumption is prioritized;

A second capability level of power consumption performance balance;

a third capability level of performance priority.

That is, different reception levels may be classified according to the demands for power consumption and performance. At a first level of capability where power consumption is preferred, the communication device expects to reduce power consumption, and therefore expects a fewer number of SSBs to receive at that level. At a third capability level of performance priority, the communication device expects to be able to receive SSBs quickly to implement the presynchronization or neighbor measurement function, and therefore expects a greater number of SSB receptions at that level. At the second capability level of the power consumption performance balance, the communication device has lower requirements for high performance and low power consumption, or the communication device has higher requirements for high performance and low power consumption, and the communication device expects a relatively moderate amount of SSB reception.

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 is the number of SSBs corresponding to each of the plurality of capability classes. As shown in table 1 below, the abscissa indicates the number of SSBs corresponding to the capability level, and the ordinate indicates the quality of the channel.

TABLE 1 number of SSBs corresponding to multiple capability classes, respectively

As can be seen from table 1, when the channel quality is greater than or equal to the first threshold, i.e., the channel quality is good, 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 smaller 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 will be appreciated that, after determining the current channel quality, the communication device may determine the number of the three receiving capability levels corresponding to each other 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 device may determine the SSB numbers corresponding to the multiple reception capability levels, respectively, based on the channel quality, and obtain multiple candidate numbers based on the SSB numbers. Further, according to the current operation state of the communication device, the number of SSBs received is determined from the plurality of candidate numbers, and the SSB corresponding to the number of SSBs received is finally received to perform presynchronization or neighbor measurement. Thus, the effect of considering both power consumption and performance can be achieved by dynamically determining the number of SSBs received according to the channel quality and the operating state of the communication device.

How to determine the operating state of the communication device is described in detail below.

In the embodiment of the application, the working states can comprise a low-power-consumption working state and a non-low-power-consumption working state.

In the embodiment of the present application, the communication device may determine that the communication device enters the low power consumption operation 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 appreciated that when the operating frequency of the communication device is less than the preset frequency threshold, the communication device may be considered as not being frequently operated by the user, and in this scenario, the application or operation with larger 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 some kind of application (e.g., a call application or a video application).

The location change rate of the communication device is smaller than the preset change threshold, and it can be considered that the communication device is not moving at high speed at present, and the requirement on performance is low. Therefore, a low power consumption mode can be entered in this scenario to save power.

The power of the communication device is smaller than the preset power threshold, that is, the power of the communication device is lower, and power saving is required. At this time, the communication device may enter a low power consumption operation state. The preset power threshold may be set to 10% by way of example, and is not particularly limited herein.

In addition, when the screen state of the communication device is the screen-off state, it can be determined that the user currently has no high requirement on the data service, and the communication device can enter a low-power-consumption working state to save power.

In the embodiment of the present application, the communication device may determine that the communication device enters the non-power consumption operation 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 larger than or equal to a preset change threshold value;

the electric quantity of the communication device is larger 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 for starting a non-low power consumption mode.

It will be appreciated that when the operating frequency of the communication device is greater than or equal to the preset frequency threshold, the current user may be considered to operate the communication device frequently, under which condition the communication device enters a non-low power consumption operating state that is required to meet the user's needs preferentially for performance preference.

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 the requirement on performance is high. Therefore, a non-low power consumption mode can be entered in the scene, and the performance requirements of the user on the communication device are preferentially met.

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

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

It follows that the power consumption and performance requirements for different operating states are different. Therefore, the communication device can select the candidate number matched with the requirement according to the current working state as the final receiving number of the SSB.

In an embodiment of the present application, the communication device determines the SSB reception quantity based on the channel quality and the operation state. The communication device may determine 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 thereon. Further, according to the current operating state (i.e., low power consumption operating state or non-low power consumption operating state) of the communication device, the SSB reception number is determined from the plurality of candidate SSB reception numbers, and finally SSBs corresponding to the SSB number are received to perform 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 device may select at least one SSB from the plurality of SSBs that matches the number of receptions based on time intervals between time domain locations of the plurality of SSBs and time domain locations of the listening opportunity, respectively, to obtain the target SSB. Wherein the listening occasions comprise paging listening occasions and/or persistent listening occasions. 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 network devices. It will be appreciated that, after the communication apparatus selects the final number of SSBs from the candidate numbers, at least one SSB matching the number of SSBs may be selected from 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 for reception SSBs that are closest to the listening occasion time domain location and match the number of SSBs received.

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 occasion may be selected for reception.

In another possible implementation, 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 occasion, and select the SSB matching the number of SSBs received 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, the method for receiving 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 a candidate number for pre-synchronization SSB based on the channel quality.

Here, the communication device 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 capability level of priority of power consumption, a second candidate number corresponding to a second capability level of balanced power consumption performance, and a third candidate number corresponding to a third capability level of priority of performance based on the channel quality.

Step 604: the communication device obtains the receiving quantity of the presynchronized SSB from the candidate quantity according to the working state.

Here, the operation states of the communication apparatus include: a low power consumption operating state, and a non-low power consumption operating state.

It will be appreciated that the communication device determines the number of pre-synchronization SSB receptions from the first number of candidates, the second number of candidates, and the third number of candidates determined in step 603 according to the operation state.

For example, if the current operating state of the communication device is a low power consumption operating state, a first candidate number corresponding to a first capability with priority of power consumption may be selected. And if the current working state of the communication device is a non-low-power-consumption working state, selecting a third candidate number corresponding to a third capability with priority performance as the presynchronization SSB receiving number.

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

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

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

Step 607: the communication device determines a candidate number for neighbor cell measurement SSB based on the channel quality.

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

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

It will be appreciated that the communication device determines the number of neighbor measurement SSB receptions from the first, second, and third candidate numbers determined in step 603 according to the operation state.

For example, when the current operating state of the communication device is a low-power-consumption operating state, a first candidate number corresponding to a first capability with priority of power consumption may be selected as the neighbor cell measurement SSB reception number. And if the current working state of the communication device is a non-low-power-consumption working state, selecting a third candidate number corresponding to a third capability with priority performance as the neighbor cell measurement SSB receiving number.

Step 609: the communication device determines the number of neighbor measurement SSB receiving candidates and determines the neighbor measurement SSB position matching the number of neighbor measurement SSB receiving candidates.

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

It follows that in the embodiment of the present application, the communication apparatus determines the reception number of SSBs based on the channel quality and the operation state. Specifically, the communication apparatus may determine the number corresponding to each of the plurality of reception capability levels based on the channel quality, and obtain a plurality of candidate numbers based thereon. Further, according to the current operating state of the communication device (i.e., the low power consumption operating state or the non-low power consumption operating state), the number of SSBs received is determined from the plurality of candidate numbers, and finally the SSB corresponding to the number of SSBs received is received to perform presynchronization or neighbor cell measurement. Thus, the received quantity of the SSB is dynamically determined through the channel quality and the working state of the communication device, and the power consumption and the performance of the communication device can be considered.

The embodiment of the application provides a communication device, which can execute the SSB receiving method provided by any embodiment. The device may be used as a terminal device or a chip (e.g., a Modem (Modem), a system on chip (system on chip), etc.) for controlling power consumption in the terminal device.
