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 scenario to which the selection method of the SSB set 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 pressure of the chip to turn off part of the monitoring function, so as to save the power consumption of the terminal device. When the 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 where the terminal device needs to perform the neighbor cell measurement, referring to a windowing 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 drawing), a first SSB (SSB 2' in the drawing) 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 or voltage in different working modes through the DVFS technology, and the purpose of energy saving is achieved.

However, in the power consumption control method in the related art, the working modes of the terminal device in different time domain positions are divided according to SSBs determined by the preset number of SSBs, so that the terminal device further receives the SSBs to perform pre-synchronization or neighbor cell measurement. However, when determining the number of SSBs, only a preset fixed number of SSBs are received without considering the channel quality and power consumption mode of the target channel of the terminal device. Therefore, the selected SSB quantity is not optimal in power consumption, and especially, the selected SSB quantity is wasted in a scenario with good channel quality, which may cause excessive power consumption, cause unnecessary windowing of the terminal device, and reduce the endurance of the terminal.

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

Specifically, in the SSB receiving method provided in the embodiment of the present application, the communication device may determine the number of SSBs received according to the channel quality; and receiving at least one SSB based on the received number. That is, the communication apparatus can determine the number of SSBs matching the channel quality on a targeted basis. Thus, the number of SSBs received by the communication device under the condition of good channel quality is reduced, and power consumption is optimized. The number of SSBs received by the communication device under the condition of poor channel quality is increased, so that the success rate of pre-synchronization and/or neighbor cell measurement is improved.

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 schematic flow chart of a method for receiving an 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 an SSB may include the following steps.

Step 501, determining the receiving number of the SSBs according to the channel quality.

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 apparatus. 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 apparatus.

In this embodiment, the communication device may measure a channel state of a broadcast channel between the network device and the communication device to obtain a channel quality of the broadcast channel. 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.

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 be missed, and therefore, in this scenario, the communication apparatus needs to receive multiple SSBs to ensure the performance of the communication apparatus.

Based on this, the communication apparatus can determine the number of receptions of the SSBs required for the current channel quality from the channel quality.

In the embodiment of the present application, the receiving number of SSBs refers to the minimum SSB number that meets the performance requirement under the channel quality condition. That is to say, in the embodiment of the present application, the receiving number of SSBs determined by the communication apparatus according to the channel quality, that is, the number of candidate SSBs matching the channel quality, is the minimum number of SSBs that meets the performance requirement of the communication apparatus at the current channel quality.

The performance requirement refers to a requirement for performing pre-synchronization and/or neighbor measurement by the communication apparatus, and is related to a function of the SSB, for example, the performance requirement may be a requirement for receiving a quality of the SSB (including the pre-synchronization SSB and/or the neighbor measurement SSB), or a requirement for receiving a delay of the SSB (including the pre-synchronization SSB and/or the neighbor measurement SSB), and the like.

For example, when the channel quality is good, the communication apparatus receives 1 or more SSBs, and can successfully complete the function of pre-synchronization or neighbor cell measurement. However, in the case of satisfying the performance requirement of the communication apparatus, in order to further reduce the power consumption of the communication apparatus and extend the endurance time of the communication apparatus, the communication apparatus may select the minimum number of SSBs (i.e., 1 SSB) to receive the SSBs. That is, the number of minimum SSBs to meet the performance requirement at the channel quality is 1. When the channel quality is general, when the communication apparatus selects 1 SSB, it may result in that the communication apparatus cannot receive the SSB, and thus the communication apparatus needs to select multiple SSBs (for example, more than 2 SSBs) to complete the reception of the SSBs, and then the minimum number of SSBs that meet the performance requirement under the channel quality is 2. When the channel quality is poor, if the communication apparatus selects 1 or 2 SSBs, the communication apparatus may not receive the SSBs, and therefore the communication apparatus needs to select more SSBs (for example, 3 SSBs) to complete the reception of the SSBs, and the minimum number of SSBs that meet the performance requirement under the channel quality is 3.

Here, the communication apparatus can determine the quality of the channel by a preset threshold.

For example, when the channel quality includes a reference signal received power, the communication device may determine a relationship between a currently measured reference signal received power and a preset first power threshold and a second power threshold to determine the channel quality. When the reference signal received power is greater than the first power threshold, it may be determined that the current channel quality is better. When the reference signal received power is less than or equal to the first power threshold and greater than the second power threshold, it may be determined that the current channel quality is general. In addition, when the reference signal received power is less than or equal to the second power threshold, the current channel quality is determined to be poor.

Similarly, the communication apparatus may determine the quality of the channel quality based on a quality threshold corresponding to the reference signal received quality, a loss threshold corresponding to the path loss, or a signal to interference plus noise ratio threshold corresponding to the signal to interference plus noise ratio, which is not limited in this embodiment.

It should be noted that the threshold for determining the channel quality may be configured in advance by the network device, or may be defined in advance by the communication apparatus, which is not limited in this embodiment of the present application.

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.

Step 502: the communication device receives at least one SSB based on the number of receptions.

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 receiving at least one SSB based on the received number. That is, the communication apparatus can determine the number of SSBs matching the channel quality on a targeted basis. Thus, the number of SSBs received by the communication device under the condition of good channel quality is reduced, and power consumption is optimized. The number of SSBs received by the communication device under the condition of poor channel quality is increased, so that the success rate of pre-synchronization and/or neighbor cell measurement is improved.

How the communication device determines the number of SSBs received is described in detail below.

In one possible implementation manner, the determining the receiving number of SSBs according to the channel quality in step 501 may be implemented by:

step 5011, the communication apparatus may determine a reception number of SSBs corresponding to the channel quality based on the first mapping relationship; the first mapping relationship represents a corresponding relationship between the channel quality and the minimum SSB quantity meeting the performance requirement under the channel quality.

It is to be appreciated that the first mapping relationship can indicate a minimum number of SSBs required by the communication apparatus to enable pre-synchronization or neighbor cell measurement functionality at each channel quality. For example, the first mapping may indicate: the channel quality is greater than the first channel quality, the corresponding minimum SSB number is 1, the channel quality is less than the first channel quality, the corresponding minimum SSB number is 2, and so on. Here, the configuration mode of the first mapping relationship is not limited in the embodiment of the present application.

It should be noted that the first mapping relationship may be configured by the communication apparatus before shipment, or may be configured by the network device through signaling, and the embodiment of the present application is not limited.

It should be further noted that the first mapping relationship may be determined by a result of simulation calculation, and configured for each communication apparatus before the communication apparatus is shipped. The setting manner of the first mapping relationship is not limited in the embodiment of the present application.

It is understood that, in the embodiment of the present application, the communication apparatus may pre-configure the first mapping relationship between different channel qualities and the minimum SSB number. That is, the communication apparatus may determine, based on the first mapping relationship, a minimum number of SSBs that satisfy performance requirements of the communication apparatus when different channel qualities are achieved, and receive corresponding SSBs. Therefore, the problem of power consumption waste caused by the fact that the communication device receives a fixed number of SSBs under different channel qualities can be avoided. Therefore, the power consumption of the communication device is reduced, and the standby time of the communication device is prolonged.

In another embodiment, the step 501 of determining the receiving number of SSBs according to the channel quality may be implemented by:

step 5012, the communications apparatus may determine, based on the second mapping relationship, a range of SSBs corresponding to the channel quality; the second mapping relationship characterizes a correspondence between channel quality and a range of SSBs that meet performance requirements at the channel quality.

In step 5013, the communication apparatus may select the minimum number of SSBs from the range of the number of SSBs corresponding to the channel quality as the reception number of SSBs.

It is to be appreciated that the second mapping relationship can indicate a plurality of SSBs required by the communications apparatus to enable pre-synchronization or neighbor measurement functionality at each channel quality. For example, the second mapping relationship may include: the channel quality is greater than the first channel quality, the corresponding number of SSBs may be greater than or equal to 1, the channel quality is less than the first channel quality, and the corresponding number of SSBs may be greater than or equal to 2. Here, the configuration mode of the second mapping relationship is not limited in the embodiment of the present application.

It should be noted that the second mapping relationship may be configured by the communication apparatus before shipment, or may be configured by the network device through signaling, and the embodiment of the present application is not limited.

It should be noted that the second mapping relationship may be determined by a result of simulation calculation, and configured for each communication apparatus before the communication apparatus is shipped. The setting manner of the second mapping relationship is not limited in the embodiment of the present application.

In the embodiment of the present application, after the communication apparatus determines the SSB number range based on the second mapping relationship, the communication apparatus selects the minimum SSB number in the SSB number range as the reception number of SSBs. That is, when the channel quality is good, the communication apparatus may select the minimum SSB number (i.e., 1) from the range of SSBs numbers of 1 or more. When the channel quality is general, the communication apparatus may select the minimum SSB number (i.e., 2) from the range of SSBs numbers of 2 or more. When the channel quality is poor, the communication apparatus may select the minimum SSB number (i.e., 3) from the range of SSBs numbers equal to or greater than 3.

It is understood that, in the embodiment of the present application, the communication apparatus may pre-configure a second mapping relationship between different channel qualities and a range of received SSBs, and select a minimum SSB number as the received SSBs. That is, the communication apparatus may determine, based on the second mapping relationship, a range of SSBs that satisfy performance requirements of the communication apparatus when the channel qualities are different, select the minimum SSBs as the SSBs receiving number, and then receive the corresponding SSBs. Thus, the number of SSBs received by the communication device under the condition of good channel quality is reduced, and power consumption is optimized. The number of SSBs received by the communication device under the condition of poor channel quality is increased, so that the success rate of pre-synchronization and/or neighbor cell measurement is improved.

It should be understood that the communication apparatus may select the number of matched SSBs according to the channel quality in a low power consumption scenario or a non-low power consumption scenario, so as to receive the SSBs for pre-synchronization or neighbor cell measurement.

In addition, in some embodiments, to reduce the processing complexity of the communication apparatus, the communication apparatus may select the number of matched SSBs according to the channel quality only when it is in the low power consumption mode, so as to receive the SSBs for pre-synchronization or neighbor measurement. That is, before determining the reception number of SSBs according to the channel quality in step 501, the following steps may be further included:

step 500, determining the channel quality when the communication device is in a low power mode.

In some embodiments, a communication device in a low power mode may determine the number of receptions of an SSB based on channel quality; and receiving at least one SSB based on the received number. That is, the communication apparatus in the low power consumption mode can acquire the channel quality, and the number of SSBs matching the channel quality is determined with specificity. Thus, the number of SSBs received by the communication device under the condition of good channel quality is reduced, and power consumption is optimized. The number of SSBs received by the communication device under the condition of poor channel quality is increased, so that the success rate of pre-synchronization and/or neighbor cell measurement is improved.

In some embodiments, when the communication apparatus is in the low power consumption mode, the communication apparatus determines the minimum number of SSBs to be received according to performance requirements corresponding to different channel qualities, and further performs SSB reception. That is, the communication apparatus in the low power consumption mode, after acquiring the channel quality, determines the minimum number of SSBs matching the channel quality in a targeted manner according to different channel qualities. Therefore, the problem of power consumption waste caused by the fact that the communication device in the low power consumption mode receives a fixed number of SSBs under different channel qualities can be avoided. Therefore, the power consumption of the communication device in the low power consumption mode is reduced, and the standby time of the communication device is prolonged.

In the embodiment of the present application, the communication apparatus may determine that it is in the low power consumption mode when at least one of the following conditions is satisfied:

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; a switch instruction is used to initiate the low power mode.

When the power of the communication device is less than the preset power threshold, that is, the power of the communication device is low, the communication device enters a low power consumption mode at this time in order to prevent the communication device from being powered off due to too low power. That is to say, after the electric quantity is less than the preset electric quantity threshold value, the communication device can select the minimum SSB quantity meeting the performance requirement according to the channel quality, thereby reducing the power consumption of the communication device and improving the cruising ability. For example, the preset charge threshold may be set to 10%, and is not limited herein.

When the temperature of the communication device is higher than the preset temperature threshold, that is, the temperature of the communication device is too high, in order to prevent the communication device from damaging the hardware structure due to the too high temperature, the communication device enters a low power consumption mode at this time. That is, after the temperature of the communication device is higher than the temperature threshold, the minimum number of SSBs meeting the performance requirement can be selected according to the channel quality, so as to reduce the power consumption of the communication device, thereby achieving the purpose of reducing the temperature. For example, the preset temperature threshold may be set to 43 degrees celsius (° c).

It should be noted that the preset electric quantity threshold and the preset temperature threshold may be determined according to a result of a simulation experiment, and configured for each communication apparatus before the communication apparatus leaves a factory. The preset electric quantity threshold and the preset temperature threshold can also be set by a user according to the requirement of the user, and the setting mode of the preset electric quantity threshold and the preset temperature threshold is not limited in the embodiment of the application.

When the screen state of the communication device is switched from the on-screen state to the off-screen state, it can be determined that the user does not have high requirements for the data service currently, and at this time, the communication device enters a low power consumption mode. That is to say, when the communication device is in the screen-off state, the minimum SSB number meeting the performance requirement can be selected according to the channel quality, so that the power consumption of the communication device is reduced, and the cruising ability is improved.

In addition, when the communication device receives a switching instruction for starting the low power consumption mode, it can be determined that the user does not have high demand for the data service currently, and at this time, the communication device enters the low power consumption mode. That is, after receiving the instruction to switch to the low power consumption mode, the communication device may select the minimum SSB number that meets the performance requirement according to the channel quality, thereby reducing the power consumption of the communication device and improving the cruising ability.

In some embodiments, the communications apparatus may select at least one SSB from the plurality of SSBs that matches the reception number based on a time interval between the time domain location of the plurality of SSBs and the time domain location of the listening opportunity, respectively.

Wherein the listening occasion includes a paging listening occasion and/or a persistent listening occasion.

Here, the plurality of SSBs refers to SSBs transmitted by the network device. It is understood that, after determining the number of SSBs, the communication apparatus may select the SSBs to be received from the plurality of SSBs sent by the network device according to the determined number of SSBs.

In one possible implementation, the communication device may select the number of SSBs closest to the listening opportunity time domain location for reception after determining the number of SSBs.

For example, when the communication apparatus determines that the number of SSBs 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 according to an operation mode of the communication device in the time interval.

Here, the operation mode may include a deep sleep mode, a light sleep mode, and an active mode.

In some embodiments, if the communications apparatus needs to enter the deep sleep mode between the time domain position of the SSB and the time domain position of the listening opportunity, the communications apparatus may select an SSB from a plurality of SSBs sent by the network device, for which the time interval between the time domain position of the SSB and the time domain position of the listening opportunity is greater than a first threshold (e.g., 3 milliseconds). Here, the first threshold may be determined according to a minimum switching time period required for the terminal device to switch from the active mode to the sleep mode.

For example, referring to the first power consumption diagram shown in fig. 6, before the paging listening opportunity PF, there are multiple SSBs (i.e., SSB1, SSB2, and SSB3), and the minimum number of SSBs corresponding to the current channel quality is 1. At this time, the communication device may determine time intervals between the paging listening occasions and SSBs 1, SSBs 2, and SSBs 3, respectively, and select an SSB (i.e., SSB3) from among SSBs 1, SSBs 2, and SSBs 3 whose time interval is greater than a first threshold as a final selected SSB. Based on this, the communication device enters a deep sleep mode upon receiving SSB3, as shown by curve 63 in fig. 6.

In some embodiments, if the communication apparatus needs to enter the doze mode between the time domain position of the SSB and the time domain position of the listening opportunity, the communication apparatus may select an SSB, from among a plurality of SSBs transmitted by the network device, whose time interval between the time domain position of the SSB and the time domain position of the listening opportunity is less than or equal to a first threshold and greater than a second threshold. Here, the second threshold may be determined according to a minimum switching time period required for the terminal device to switch from the deep sleep mode to the shallow sleep mode.

For example, referring to the first power consumption diagram shown in fig. 6, before the paging listening opportunity PF, there are multiple SSBs (i.e., SSB1, SSB2, and SSB3), and the minimum number of SSBs corresponding to the current channel quality is 1. At this time, the communication apparatus may determine time intervals between the paging listening opportunity and SSBs 1, SSBs 2, and SSBs 3, respectively, and select an SSB (i.e., SSB2) having a time interval less than or equal to the first threshold and greater than the second threshold from among SSBs 1, SSBs 2, and SSBs 3 as a final selected SSB. Based on this, the communication device enters the doze mode upon receiving the SSB2, as shown by curve 62 in fig. 6.

In some embodiments, if the communications apparatus needs to enter the active mode between the time domain location of the SSB and the time domain location of the listening opportunity, the communications apparatus may select an SSB from a plurality of SSBs transmitted by the network device, where a time interval between the time domain location of the SSB and the time domain location of the listening opportunity is less than or equal to a second threshold.

For example, referring to the first power consumption diagram shown in fig. 6, before the paging listening opportunity PF, there are multiple SSBs (i.e., SSB1, SSB2, and SSB3), and the minimum number of SSBs corresponding to the current channel quality is 1. At this time, the communication apparatus may determine time intervals between the paging listening opportunity and SSBs 1, SSBs 2, and SSBs 3, respectively, and select an SSB (i.e., SSB1) having a time interval of less than or equal to the second threshold from among SSBs 1, SSBs 2, and SSBs 3 as a final selected SSB. Based on this, the communication device enters the active mode upon receiving the SSB1, as shown by curve 61 in fig. 6.

In some embodiments, after the communication apparatus matches the minimum SSB number that satisfies the performance requirement according to different channel qualities, according to the determined minimum SSB number, a plurality of SSB sets that satisfy the minimum SSB number are determined from a plurality of SSBs sent by the network device. Further, the communications apparatus can determine an amount of power consumption to window the plurality of SSB sets and select a SSB set from the plurality of SSB sets that has a least amount of power consumption to receive.

Illustratively, referring to fig. 6, when the channel quality is good, the communication apparatus determines that the minimum number of SSBs to meet the performance requirement is 1. Then, the communication apparatus determines three SSB sets, namely, SSB set 1 composed of SSBs 1, SSB set 2 composed of SSBs 2, and SSB set 3 composed of SSBs 3, from among the SSBs sent by the network device.

Further, the communication device may determine the power consumption amount for windowing each SSB set according to the time domain location of the SSB set and the time domain location of the paging listening opportunity.

Here, the communication apparatus may determine, from the time domain positions of the SSB sets and the time domain position of the paging listening occasion, the magnitudes of the voltage and/or the frequency at the time domain position of the SSB set and the time domain position of the paging listening occasion when each SSB set is windowed, and the magnitudes of the voltage and/or the frequency at the time interval between the time domain position of the SSB set and the time domain position of the paging listening occasion. Based on this, the communication device may calculate the voltage and/or frequency magnitudes of each SSB set that are windowed over the entire time domain, resulting in an amount of power consumption for windowing each SSB set.

Further, the communication apparatus may compare the power consumption amounts of windowing the SSB set 1, the SSB set 2, and the SSB set 3, and select the SSB set having the smallest power consumption amount. For example, the SSB set with the smallest power consumption is SSB set 1, and based on this, the communication apparatus may receive the SSBs in SSB set 1 for pre-synchronization.

In an embodiment of the present application, referring to the flowchart shown in fig. 7, a method for receiving an SSB provided in the embodiment of the present application may include the following steps:

step 701: the communication device enters a 5G standby mode.

Step 702: it is determined whether the communication device is enabled in a low power mode.

Here, if the communication apparatus enables the low power consumption mode, step 703 is executed; if the communication device does not enable the low power mode, step 708 is performed.

Here, the communication apparatus is in the low power consumption mode when at least one of the following conditions is satisfied:

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.

Step 703: the communication device determines the number of receptions of the pre-synchronization SSBs based on the channel quality.

Here, the communication apparatus determines the reception number of the pre-synchronization SSBs according to the channel quality. Wherein, the receiving number of the pre-synchronization SSBs refers to the minimum number of SSBs meeting the pre-synchronization requirement under the channel quality.

In some embodiments, the channel quality comprises at least one of reference signal received power, reference signal received quality, path loss, signal to interference plus noise ratio.

In some embodiments, the communication apparatus may determine a reception number of pre-synchronization SSBs corresponding to the channel quality based on the first mapping relation; the first mapping relation represents the corresponding relation between the channel quality and the minimum pre-synchronization SSB quantity meeting the performance requirement under the channel quality.

In other embodiments, the communication device determines a pre-synchronization SSB number range corresponding to the channel quality based on a second mapping relationship; the second mapping relationship represents a corresponding relationship between the channel quality and the SSB quantity range satisfying the pre-synchronization requirement under the channel quality. And selecting the minimum SSB number from the range of the pre-synchronization SSB numbers as the receiving number of the pre-synchronization SSB.

Step 704: the communication apparatus selects SSBs satisfying the reception number based on the reception number of the pre-synchronization SSBs, and determines the selected pre-synchronization SSBs.

In some embodiments, the communication device selects at least one SSB from the plurality of SSBs that matches the received number based on a time interval between a time domain location of the plurality of SSBs and a time domain location of the listening opportunity, respectively, resulting in the selected presynchronization SSB.

For example, if the channel quality is good, the communication device may determine the minimum SSB number to meet the performance requirement of the communication device to be 1 based on the first mapping relationship or the second mapping relationship. That is, the communication apparatus needs to receive 1 SSB to perform presynchronization. Referring to fig. 8A, which is a power consumption diagram of fig. two, there are a plurality of SSBs (i.e., SSBs 1, SSBs 2, and SSBs 3) before the paging listening opportunity, and if the communication apparatus selects SSB1 as the final selected SSB, the communication apparatus is in the active mode between a time before the time domain position start time of SSB1 reaches and the end of the paging listening opportunity. As shown by curve 81 in fig. 8A.

For example, if the channel quality is general, the communication device may determine the minimum number of SSBs to satisfy the performance requirement of the communication device to be 2 based on the first mapping relation or the second mapping relation. That is, the communication apparatus needs to receive 2 SSBs to perform presynchronization. Referring to the second power consumption diagram shown in fig. 8A, there are multiple SSBs (i.e., SSBs 1, SSBs 2, and SSBs 3) before the paging listening opportunity, and if the communication apparatus selects SSBs 1 and SSBs 2 as the final selected SSBs, the communication apparatus is in the active mode between a time point before the start time of the time domain position of receiving SSB1 reaches and the end of the paging listening opportunity at the time domain position of receiving SSB 2. As shown by curve 82 in fig. 8A.

In addition, if the channel quality is poor, the communication device may determine the minimum number of SSBs that meet the performance requirement of the communication device to be 3 based on the first mapping relationship or the second mapping relationship. That is, the communication apparatus needs to receive 3 SSBs to perform presynchronization. Referring to the second power consumption diagram shown in fig. 8A, there are multiple SSBs (i.e., SSB1, SSB2, and SSB3) before the paging listening opportunity, and if the communication apparatus selects SSB1, SSB2, and SSB3 as the final selected SSB, the communication apparatus is in the active mode between a time point before the time point of receiving SSB3, a time point of receiving SSB2, a time point before the time point of receiving SSB1 reaches the starting time point, and the end of the paging listening opportunity. As shown by curve 83 in fig. 8A.

Step 705: the communication device judges whether to perform neighbor measurement.

Here, if the communication apparatus needs to perform the neighbor cell measurement, step 706 is performed; if the communication apparatus does not perform the neighbor cell measurement, step 708 is performed.

Step 706: the communication device determines the receiving number of the neighbor cell measurement SSBs according to the channel condition.

Here, the communication apparatus may determine the reception number of the neighbor cell measurement SSB according to the channel quality. The receiving number of the neighbor cell measurement SSBs is the minimum SSB number that meets the performance requirement of neighbor cell measurement under the channel quality condition.

In some embodiments, the communication device determines, based on the first mapping relationship, a received number of neighbor cell measurement SSBs corresponding to the channel quality; the first mapping relation represents the corresponding relation between the channel quality and the minimum neighbor cell measurement SSB quantity meeting the neighbor cell measurement requirement under the channel quality.

In other embodiments, the communication device determines, based on the second mapping relationship, a neighbor cell measurement SSB number range corresponding to the channel quality; the second mapping relationship represents a corresponding relationship between the channel quality and an SSB quantity range meeting the measurement requirement of the adjacent cell under the channel quality. And selecting the minimum SSB number from the neighbor measurement SSB number range as the receiving number of the neighbor measurement SSB.

Step 707: the communication device selects the SSBs meeting the receiving quantity according to the receiving quantity of the neighbor cell measurement SSBs, and determines the selected neighbor cell measurement SSBs.

In some embodiments, the communication device selects at least one SSB from the plurality of SSBs that matches the received number of the neighbor measurement 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 selected neighbor measurement SSBs.

For example, if the channel quality is good, the communication device may determine the minimum SSB number to meet the performance requirement of the communication device to be 1 based on the first mapping relationship or the second mapping relationship. That is, the communication device needs to receive 1 SSB for neighbor cell measurement. Referring to fig. 8B, a power consumption diagram of a third embodiment, there are multiple SSBs (i.e., SSBs 1, SSBs 2, and SSBs 3) after the paging listening time, and if the communication apparatus selects SSB1 as the final selected SSB, the communication apparatus is in the active mode between a time before the time domain position start time of the pre-synchronization SSB reaches and a time after the end time of the neighbor measurement SSB1 reaches. As shown by curve 84 in fig. 8B.

For example, if the channel quality is general, the communication device may determine the minimum number of SSBs to satisfy the performance requirement of the communication device to be 2 based on the first mapping relation or the second mapping relation. That is, the communication device needs to receive 2 SSBs for neighbor measurements. Referring to the third power consumption diagram shown in fig. 8B, after the paging listening opportunity, there are multiple SSBs (i.e., SSB1, SSB2, and SSB3), and if the communication apparatus selects SSB1 and SSB2 as the final selected SSB, the communication apparatus is in the active mode between a certain time before the time domain position start time of the pre-synchronization SSB reaches and a certain time after the end time of the neighbor measurement SSB2 reaches. As shown by curve 85 in fig. 8B.

In addition, if the channel quality is poor, the communication device may determine the minimum number of SSBs that meet the performance requirement of the communication device to be 3 based on the first mapping relationship or the second mapping relationship. That is, the communication device needs to receive 3 SSBs for neighbor measurements. Referring to the third power consumption diagram shown in fig. 8B, after the paging listening opportunity, there are multiple SSBs (i.e., SSB1, SSB2, and SSB3), and if the communication apparatus selects SSB1, SSB2, and SSB3 as the final selected SSB, the communication apparatus is in the active mode between a certain time before the time domain location start time of the pre-synchronization SSB reaches and a certain time after the end time of the neighbor measurement SSB3 reaches. As shown by curve 86 in fig. 8B.

Step 708: the communication device receives the selected pre-synchronization SSB and/or the selected neighbor measurement SSB.

Therefore, in the embodiment of the application, when the communication device is in the low power consumption mode, the communication device may determine, according to different channel qualities, the minimum SSB number that meets the pre-synchronization requirement and/or the neighbor cell measurement requirement. The communication device receives the corresponding SSBs based on the determined minimum number of SSBs to perform pre-synchronization or neighbor cell measurements. Thus, the number of SSBs received by the communication device under the condition of good channel quality is reduced, and power consumption is optimized. The number of SSBs received by the communication device under the condition of poor channel quality is increased, so that the success rate of pre-synchronization and/or neighbor cell measurement is improved.
