Please refer to FIG. 1 , which shows a schematic structural diagram of a mobile communication system provided by an embodiment. The mobile communication system may be a 5G system, also known as a new radio (new radio, NR) system. The mobile communication system includes: an access network device 120 and a terminal 140 .

The access network device 120 may be a base station. For example, the base station may be a base station adopting a centralized distributed architecture in a 5G system, such as a gNB. When the access network device 120 adopts a centralized distributed architecture, it generally includes a centralized unit (central unit, CU) and at least two distributed units (distributed unit, DU). The centralized unit is provided with a protocol stack of a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer, a radio link layer control protocol (Radio Link Control, RLC) layer, and a media access control (Media Access Control, MAC) layer; distribution unit A physical (Physical, PHY) layer protocol stack is set in the device, and the specific implementation manner of the access network device 120 is not limited in this embodiment of the present disclosure. The access network device 120 further includes a transceiver, and the transceiver is a multiple-input multiple-output (Multiple-Input Multiple-Output, MIMO) antenna that supports beamforming. Optionally, the transceiver is a beam scanning such as TRP. node.

Optionally, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a New Radio (NR); or, the wireless air interface may also be a 5G-based update. The wireless air interface of the next generation mobile communication network technology standard.

Terminal 140 may be a device that provides voice and/or data connectivity to a user. The terminal may communicate with one or more core networks via a Radio Access Network (RAN), and the terminal 140 may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, For example, it may be a portable, pocket-sized, hand-held, computer built-in or vehicle mounted mobile device. For example, Subscriber Unit, Subscriber Station, Mobile Station, Mobile Station, Remote Station, Access Point, Remote Terminal, Access Terminal, User Terminal, User Agent, User Device, or User Equipment.

It should be noted that the mobile communication system shown in FIG. 1 may include multiple access network devices 120 and/or multiple terminals 140, and FIG. 1 shows one access network device 120 and one terminal 140 to An example is given, but this embodiment does not limit it.

In the 5G system, the access network equipment and terminals will use high-frequency frequency bands above 6 GHz. However, in the high-frequency frequency band, the attenuation of high-frequency signals is large, resulting in a small coverage of high-frequency signals. In order to solve the problem of poor coverage and large attenuation of high-frequency signals, in the 5G system, the access network equipment will use beam scanning to send high-frequency signals to terminals in the managed cell.

In the related art, in order to realize beam scanning, the access network device sets up a beam scanning node such as a Transmission Reception Point (TRP) for the managed cell, and uses the beam scanning node to transmit a scanning beam, and then changes the scanning beam by changing the scanning beam. The beam direction of the beam completes the beam scan of the entire cell. For example, as shown in (a) of FIG. 2 , when the access network device 220 transmits a paging signal to the terminal 240 in the cell by means of beam scanning, it takes the position shown in the figure as the scanning starting point, and scans in a clockwise direction for one cycle (continuously). Change the beam direction of the scanning beam 221), that is, complete the scanning of the entire cell. As shown in (b) of Figure 2, in the time domain (t)-frequency (f) coordinate axis, the time-frequency unit corresponding to each square indicates the scanning beam containing the paging signal, and the beam direction of each square corresponding to the scanning beam is different, Then, the beam scanning period required for a complete scanning of the access network equipment for one cycle is 16 time domain units.

When the terminal 240 wakes up from the DRX cycle and receives its own paging signal, it responds to the paging signal, thereby completing the entire paging process. However, if the terminal 240 wakes up from the DRX cycle, and the scanning beam 221 just scans the terminal 240, the terminal 240 needs to remain awake until the next scanning cycle to receive the paging signal in time, resulting in the terminal 240 in each DRX cycle. It is necessary to maintain a long wake-up state (the wake-up duration is greater than or equal to one beam scanning period, that is, greater than or equal to 16 time domain units), which is not conducive to power saving of the terminal.

Please refer to FIG. 3A , which shows a flowchart of a method for sending a paging signal provided by an embodiment. This embodiment is illustrated by taking the paging signal sending method applied to the mobile communication system shown in FIG. 1 as an example. The method includes:

In step 301, the access network device generates a paging signal.

Optionally, the paging signal includes a paging indication (Paging Indication) and/or a paging (Paging) message. Wherein, the paging indication is used to indicate whether the terminal is paged, and the paging message includes information such as calling party identification and paging time.

Optionally, the paging signal generated by the access network device is carried inside the synchronization information block (Synchronization Signal Block, SS Block), or after the synchronization information block, so that after the terminal completes synchronization according to the synchronization signal in the synchronization information block, further Respond to paging according to the paging signal.

In step 302, the access network device simultaneously transmits a paging signal to the terminal using n scanning beams on n subbands, where n is a positive integer greater than 1.

Wherein, the terminal is a general reference, which is used to indicate at least one terminal.

After the access network device generates the paging signal, it extends the paging signal to n sub-bands, and uses scanning beams on each sub-band to simultaneously send the paging signal to the terminals in the covered cells. Optionally, the n subbands are consecutive n subbands.

Optionally, the beam scanning areas of the scanning beams corresponding to each subband are different, and the collection of the beam scanning areas of the respective scanning beams is the range of the cells covered by the access network device. Illustratively, the beam scanning area of the scanning beam corresponding to each subband occupies 1/n of the coverage area of the access network equipment.

For example, as shown in (a) of FIG. 3B, the paging signal is extended to 4 sub-bands, and the scanning beams corresponding to each sub-band are the first scanning beam 321, the second scanning beam 322, the third scanning beam 323, the Four scanning beams 324 . Among them, the first scanning beam 321 corresponds to the beam scanning area 1 (90° sector area in the upper right corner), the second scanning beam 322 corresponds to the beam scanning area 2 (90° sector area in the lower right corner), and the third scanning beam 323 corresponds to the beam scanning area 3 (90° fan-shaped area in the lower left corner), the fourth scanning beam 324 corresponds to beam scanning area 4 (90° fan-shaped area in the upper left corner), that is, the beam scanning area of each scanning beam occupies 1/4 of the complete beam scanning area.

Since the coverage of a single scanning beam is limited, in order to achieve complete coverage of the scanning area of each beam, the access network equipment needs to constantly change the scanning direction of the scanning beam on each subband. That is, for the same beam scanning area, the access network device can use different scanning beams in different time domain units to scan the current beam scanning area, but use one scanning beam in the same time domain unit to scan the current beam. area to scan.

Optionally, the scanning directions of the scanning beams on each subband are the same. For example, as shown in (a) of FIG. 3B , the scanning direction of each scanning beam is clockwise.

In a possible implementation manner, when the scanning directions of the scanning beams are all clockwise, among the n scanning beams, the scanning end position of the i-th scanning beam and the boundary of the fan-beam scanning area corresponding to the i+1-th scanning beam Coincidence, i<n; the scanning end position of the ith scanning beam coincides with the boundary of the sector beam scanning area corresponding to the first scanning beam, i=n.

Since the n subbands simultaneously use n scanning beams to perform beam scanning, the beam scanning period can be greatly reduced compared with the beam scanning mode adopted by the access network device in FIG. 2 . Schematically, as shown in (b) of FIG. 3B , the access network device uses 4 scanning beams on 4 subbands to perform beam scanning at the same time, and when each subband needs 4 time domain units to complete the scanning area of the respective beams. When scanning, the access network equipment needs a total of 4 time domain units to achieve complete beam scanning of the covered cells, and the access network equipment in Figure 2 (b) needs 16 time domain units to scan the covered cells. A full beam scan is performed, and the beam scan period is reduced to 1/4.

It should be noted that the time domain unit required for the subband to completely scan the beam scanning area is related to the range of the beam scanning area. The longer the domain unit, the smaller the range of the beam scanning area, and the smaller the time domain unit required for the subband to perform a complete scan of the beam scanning area. Examples are given to illustrate, but do not limit the present disclosure.

When a paging signal is sent to a terminal in a cell in the above manner, since the beam scanning period is reduced to 1/n, the paging delay of the terminal is reduced; correspondingly, the wake-up duration configured by the terminal is also reduced to 1/n of the original , that is, the terminal can be in a longer sleep state, which is conducive to saving power of the terminal.

In step 303, the terminal receives the paging signal sent by the access network device.

Correspondingly, when the terminal located in the cell covered by the access network device wakes up from the DRX cycle and scans the scanning beam to the terminal, the terminal receives the corresponding paging signal. Among them, the paging signal is sent by the access network device using n scanning beams on n subbands at the same time, the beam scanning areas of the scanning beams corresponding to each subband are different, and n is a positive integer greater than 1

Illustratively, as shown in (a) of FIG. 3B , the terminal 341 located in the beam scanning area 1 wakes up from the DRX cycle, and when the first scanning beam 321 scans the terminal, the terminal receives a corresponding paging signal.

Optionally, after receiving the paging signal, the terminal determines whether there is its own paging according to the paging indication in the paging signal, and if there is its own paging, the terminal obtains the corresponding paging message from the paging signal, And respond to the paging; if there is no own paging, the terminal discards the paging signal and enters the dormant state.

To sum up, in the method for sending a paging signal provided by the embodiments of the present disclosure, after the access network device generates the paging signal, it simultaneously uses n scanning beams with different beam scanning areas on the n subbands to send the paging signal to the terminal , thereby reducing the transmission delay of the paging signal; at the same time, the beam scanning period required for the access network equipment to completely scan the covered cells is reduced, so that the wake-up time configured by the terminal can be reduced, thereby increasing the time that the terminal is in a dormant state. , which is beneficial to the terminal power saving.

It should be noted that the above steps 301 and 302 can be independently implemented as an embodiment of the paging signal sending method on the access network device side, and step 303 can be independently implemented as an embodiment of the paging signal receiving method on the terminal side. This embodiment This is not limited.

In the above embodiment, the access network device uses 4 scanning beams on 4 subbands to send paging signals to the terminal at the same time as an example for description. Optionally, the subbands and The number n of scanning beams is determined by the number of TRPs, and/or by the number of terminals located within the range of cells covered by the access network equipment. Among them, the maximum value of n does not exceed the total number of TRPs.

In a possible implementation manner, the number of subbands and scanning beams used by the access network device to send the paging signal is proportional to the number of TRPs, that is, the more the number of TRPs set in the access network device, the more the number of TRPs sent by the access network device will be. The more subbands and scanning beams that can be used in the signal, correspondingly, the beam scanning area corresponding to each scanning beam is smaller, and the beam scanning period required for the access network equipment to completely scan the covered cells is smaller.

For example, when 4 TRPs are set in the access network equipment, the access network equipment can use 4 scanning beams in 4 subbands to send paging signals to the terminal at the same time, and the beam scanning area corresponding to each scanning beam is 90° Sector area; when 3 TRPs are set in the access network equipment, the access network equipment can use 3 scanning beams to send paging signals to the terminal in 3 subbands at the same time, and the beam scanning area corresponding to each scanning beam is 120 °Sector area.

In another possible implementation manner, the access network device determines the number of subbands to be used and the number of scanning beams according to the number of terminals in the covered cell. Optionally, when the number of terminals in the covered cell is less than the preset number, the access network device uses part of the TRP to send paging signals on the corresponding subbands, thereby reducing power consumption on the premise of ensuring paging quality; When the number of terminals in the cell is greater than the preset number, the access network equipment uses all TRPs to send paging signals on the corresponding subbands, thereby reducing the paging delay and improving the paging quality.

Optionally, the access network device also determines the number of subbands to be used and the number of scanning beams according to the time delay requirement of the terminal in the cell. For example, when the delay demand of the terminal in the cell is lower than the predetermined delay demand (that is, the terminal is a terminal with low delay demand), the access network equipment uses part of the TRP to send the paging signal on the corresponding subband, so as to ensure paging Reduce power consumption under the premise of quality; when the delay demand of the terminal in the cell is higher than the predetermined delay demand (that is, the terminal is a terminal with high delay demand), the access network equipment uses all TRPs to send paging signals on the corresponding subbands, thereby Reduce paging delay and improve paging quality.

In a possible implementation manner, each subband includes m synchronization information blocks located in consecutive m time domain units, and the synchronization information blocks carry a synchronization signal, and the paging signal generated by the access network device bears the in the sync block.

Illustratively, for any subband in the four subbands shown in (b) of FIG. 3B, as shown in FIG. 4A, the subband includes four synchronization information blocks 40 located in four consecutive time domain units, And each synchronization information block 40 includes a synchronization signal 41 , a broadcast signal 42 and a paging signal 43 .

The first time-frequency resource 431 occupied by the paging signal 43 is located after the time domain position of the synchronization signal 41 in the synchronization information block 40, so that when the terminal receives the synchronization information block 40, Synchronization is performed, and then a page response is performed according to the paging signal 43 .

In other possible implementations, as shown in FIG. 4B , the paging signal 43 is carried in each synchronization information block 40 , and the paging signal 43 has the same time domain position as the synchronization signal 41 and the broadcast signal 42 , that is, the synchronization signal 41. The broadcast signal 42 and the paging signal 43 are distributed in different frequency domain positions at the same time domain position.

As shown in FIG. 4A , the frequency band of the first time-frequency resource occupied by the paging signal 43 belongs to the frequency band of the synchronization information block 40 . For the first terminal that does not support the preset frequency band (ie, the narrow-bandwidth terminal), since the frequency band supported by the first terminal is the same as the frequency band of the synchronization information block, when the first time-frequency resource carries the paging signal corresponding to the first terminal When , the first terminal can receive the corresponding paging signal on the first time-frequency resource; and for the second terminal (ie, the broadband terminal) that supports the preset frequency band, because the frequency band supported by the second terminal is larger than the synchronization information block Therefore, when the first time-frequency resource carries the paging signal corresponding to the second terminal, the second terminal can also receive the corresponding paging signal on the first time-frequency resource. Wherein, the preset frequency band is set according to the communication standard.

It can be seen that the access network device can use the method shown in FIG. 4A to carry all paging signals in the first time-frequency resource of the frequency band to which the synchronization information block belongs, to ensure that both narrow-band terminals and broadband terminals can read the synchronization information block The paging signal is obtained in the middle, which improves the reliability of sending and receiving the paging signal.

However, if the paging signals of all terminals (including the first terminal and the second terminal) are carried in the first time-frequency resource, the time domain occupied by the synchronization information block will also increase as the content of the paging signal increases. . In the case of a large amount of paging, the beam scanning period of the access network equipment will also increase, resulting in an increase in the delay of the paging signal. Accordingly, the terminal needs to maintain a wake-up state for a longer time to receive the paging signal.

In order to solve the above problem, in a possible implementation manner, as shown in FIG. 4C , the paging signal 43 occupies the first time-frequency resource 431 and the second time-frequency resource 432 on the subband. The frequency band of the first time-frequency resource 431 is smaller or larger than the frequency band of the second time-frequency resource 432 , and the first time-frequency resource 431 is continuous with the second time-frequency resource 432 , and the frequency band of the first time-frequency resource 431 belongs to the synchronization information block 40, the frequency band of the second time-frequency resource 432 does not belong to the frequency band of the synchronization information block 40, and the frequency band of the second time-frequency resource 432 belongs to the preset frequency band supported by the second terminal. In other possible implementations, the frequency bands of the first time-frequency resource 431 and the second time-frequency resource 432 are discontinuous, that is, in FIG. 4C , the second time-frequency resource 432 is located above the frequency domain of the broadcast signal 42 , which is not correct in the present disclosure. This is limited.

In order to ensure that the first terminal can receive the paging signal on the frequency band supported by itself, the first time-frequency resource 431 is used to carry the paging signal corresponding to the first terminal and/or the second terminal, and the second time-frequency resource 432 is only used for carrying the paging signal corresponding to the first terminal and/or the second terminal. It is used to carry the paging signal corresponding to the second terminal.

Optionally, the access network device sends the resource location of the first time-frequency resource to the first terminal and the second terminal by using the minimum system information (Minimum System Information, Minimum SI), and correspondingly, the first terminal and the second terminal receive the resource location. The minimizing system information obtains the paging signal carried in the first time-frequency resource according to the resource location carried in the minimizing system information; at the same time, in order to enable the second terminal supporting broadband to obtain the paging signal carried in the second time-frequency resource paging signal, the access network device sends the resource location of the second time-frequency resource to the second terminal through other system information (Other System Information, Other SI), and correspondingly, the second terminal receives the other system information and obtains the other system information Resource location of the second time-frequency resource carried in the information.

Optionally, when the paging signals of the first terminal and the second terminal are included at the same time, the access network device preferentially carries the paging signal corresponding to the first terminal in the first time-frequency resource 431, and transmits the paging signal corresponding to the first terminal in the first time-frequency resource 431. When there is space in the resource 431 , part of the paging signal corresponding to the second terminal is carried in the first time-frequency resource 431 , and the remaining part of the paging signal corresponding to the second terminal is carried in the second time-frequency resource 432 .

Correspondingly, the first terminal obtains the paging signal from the first time-frequency resource on the subband, and the second terminal obtains the paging signal from the first time-frequency resource and/or the second time-frequency resource on the subband .

In a possible implementation manner, as shown in (a) of FIG. 4D , when the paging signal includes a paging indication and a paging message, the access network device sends the paging indication PI 1 of the first terminal to the paging indication PI 1 and the paging message. The paging message Paging 1 is carried on the first time-frequency resource 431 , and the paging indication PI 2 of the second terminal and the paging message Paging 2 are carried on the second time-frequency resource 432 .

In another possible implementation manner, since the time-frequency resources occupied by the paging indication are far smaller than the time-frequency resources occupied by the paging message, as shown in (b) of FIG. 4D , the access network device will The paging indication PI 1 and the paging message Paging 1 of a terminal and the paging indication PI 2 of the second terminal are carried on the first time-frequency resource 431, and the paging message Paging 2 of the second terminal is carried on the second time-frequency resource Resource 432 on.

Obviously, the access network device uses the method shown in FIG. 4B to carry the paging signal into two time-frequency resources, thereby increasing the frequency domain of the time-frequency resources carrying the paging signal and reducing the frequency of carrying the paging signal. The time domain of time-frequency resources; compared with the paging signal bearing method shown in Figure 4A, in the case of a larger paging volume, the beam scanning period of the access network equipment is smaller, and the paging signal delay is smaller , correspondingly, the terminal only needs to keep the wake-up state for a short time to receive the paging signal, which is beneficial to save the power of the terminal.

In the paging signal bearing modes shown in FIGS. 4A to 4C , the time-frequency resources (including the first time-frequency resource and/or the second time-frequency resource) bearing the paging signal are all located inside the synchronization information block, that is, the paging signal and the Sync information blocks are sent at the same time. In the case of sparse paging, the access network device carries the paging signal every time the synchronization information block is sent, which will cause waste of time-frequency resources.

In order to avoid waste of time-frequency resources, in another possible implementation manner, the paging signal is carried in m time-frequency resources located after the time domain positions of m synchronization information blocks, and each i group of m synchronization information blocks Corresponding to 1 group of m time-frequency resources, i is a positive integer greater than 0. Illustratively, as shown in FIG. 4E , the first time-frequency resource 431 and the second time-frequency resource 432 carrying the paging signal 43 are carried at time domain positions located in the four synchronization information blocks 40 .

The first time-frequency resource 431 is used to carry the paging signal corresponding to the first terminal and/or the second terminal, and the second time-frequency resource 432 is only used to carry the paging signal corresponding to the second terminal. The specific bearer manner is similar to the bearer manner shown in FIG. 4C , and details are not described herein again in this embodiment.

Optionally, when the paging signal bearing manner shown in FIG. 4E is adopted, the access network device will use different scanning beams to send the synchronization information block and the paging signal. In a possible implementation manner, on the basis of FIG. 3A , as shown in FIG. 4F , the above steps 302 and 303 may be replaced by the following steps.

In step 304, the access network device simultaneously transmits the synchronization signal and the broadcast signal carried on the m synchronization information blocks by using the n first scanning beams in the n subbands.

For each subband in the n subbands, the access network device uses the first scanning beam on the subband to send the synchronization signal and the broadcast signal carried on the m synchronization information blocks to the terminal.

In step 305, the terminal receives the synchronization signal and the broadcast signal carried on the m synchronization information blocks and sent by the access network device.

Correspondingly, the terminal receives, on the subband, the synchronization signal and the broadcast signal that are sent by the access network device and carried on the m synchronization information blocks, so as to perform synchronization according to the synchronization signal.

In step 306, the access network device simultaneously transmits the paging signal carried on the m time-frequency resources to the terminal by using n second scanning beams on the n subbands.

In a possible implementation, when paging is frequent in the system, the access network device uses the first scanning beam to send the synchronization signal and the broadcast signal (carried on the synchronization information block), that is, enables n on the n subbands The second scanning beam sends the paging signal carried on the time-frequency resource to the terminal, that is, the access network device sends a group of paging signals after sending a group of synchronization information blocks;

When the paging is sparse in the system, the access network device uses the first scanning beam to send i groups of m synchronization information blocks to the terminal, and then enables the second scanning beam on n subbands to send the transmission to the terminal carried on m time-frequency resources. That is, the access network device sends a group of paging signals after every i group of synchronization information blocks, so as to avoid the waste of time-frequency resources caused by frequently sending paging signals when the paging is sparse.

In step 307, the terminal receives the paging signal carried on the m time-frequency resources and sent by the access network device.

Wherein, the paging signal carried on the m time-frequency resources is sent by the access network device using n second scanning beams on the n subbands at the same time. Correspondingly, after receiving the time-frequency resource, the terminal responds to the paging according to the paging signal carried in the time-frequency resource.

Obviously, the access network device uses the method shown in FIG. 4E to carry the paging signal after the time domain position of the synchronization information block, and uses scanning beam transmission alone to avoid the access network device sending each time the paging is sparse. The time-frequency resource waste caused by the paging signal is always carried in the synchronization information block; at the same time, compared with the bearing methods shown in FIGS. 4A to 4C , the time-frequency resource occupied by the paging signal in FIG. 4E occupies a smaller time domain length, The wake-up duration configured by the terminal is correspondingly reduced, thereby further improving the power saving performance of the terminal.

For low-latency terminals such as uRLLC terminals in the communication system, in order to ensure that such low-latency terminals can respond to paging signals as soon as possible, in another possible implementation, each subband includes m consecutive time domains. m synchronization information blocks in the unit, and the paging indication in the paging signal is carried in the time-frequency resource located after the time domain position of the synchronization signal in each synchronization information block, and the paging message in the paging signal is It is carried in m time-frequency resources located after the time domain positions of m synchronization information blocks.

Illustratively, as shown in FIG. 4G , each subband includes four synchronization information blocks 40 located in four consecutive time domain units, and each synchronization information block 40 carries a synchronization signal 41 and a broadcast signal 42 . When the access network device sends the paging signal, it carries the paging indication 44 in the paging signal in the time-frequency resource after the time domain position of the synchronization signal 41, and carries the paging message 45 in the paging signal in the In the four time-frequency resources following the time domain position of the four synchronization information blocks 40 .

Correspondingly, when the uRLLC terminal receives the synchronization signal shown in FIG. 4G , as shown in FIG. 4H , the above step 303 includes the following steps.

In step 303A, the terminal detects whether the synchronization information block carries a paging indication corresponding to the terminal.

For the uRLLC terminal in the communication system, after receiving the synchronization information block sent by the access network device on the subband, the terminal parses the synchronization information block, and further detects whether it contains its own paging indication. If a paging indication including itself is detected, the following steps 303B and 303C are performed to further obtain a corresponding paging message; if a paging indication that does not include itself is detected, the following step 303D is performed.

In step 303B, if the synchronization information block carries a paging indication corresponding to the terminal, the terminal determines the PO corresponding to the paging signal as the first time domain length, and the first time domain length is m synchronization information blocks and m synchronization information blocks and m The sum of the time domain lengths corresponding to the time-frequency resources.

When detecting that the synchronization information block carries its own paging indication, the terminal knows that there will be its own paging message in the future. In order to ensure that the paging message can be received in time, the terminal needs to remain awake after receiving the synchronization information block. . Therefore, the terminal determines the PO corresponding to the paging signal as the first time domain length, that is, the terminal maintains the awake state within the first time domain length, so as to ensure that the paging carried in the m time-frequency resources after the m synchronization information blocks are acquired in time information.

Schematically, as shown in FIG. 4G , when detecting that the synchronization information block carries its own paging indication, the terminal will determine the PO as the time corresponding to the four synchronization information blocks 40 and the four time-frequency resources after the synchronization information block 40 . Sum of field lengths.

In step 303C, the terminal acquires the paging messages carried in the m time-frequency resources.

Further, the terminal maintains an awake state under PO, and acquires the paging messages carried in the m time-frequency resources after the synchronization information block, so as to complete the paging according to its own paging messages.

In step 303D, if the synchronization information block does not carry the paging indication corresponding to the terminal, the terminal determines the PO corresponding to the paging signal as the second time domain length, and the second time domain length is the length corresponding to the m synchronization information blocks time domain length.

When it is detected that the synchronization information block does not carry its own paging indication, the terminal knows that there is no subsequent paging message of its own, and determines the PO corresponding to the paging signal as the time domain length corresponding to the m synchronization information blocks (ie The second time domain length), thereby entering a sleep state after receiving m synchronization information blocks to achieve the effect of power saving.

Optionally, the access network device configures only m time-frequency resources (carrying paging messages) after the time domain position of the synchronization information block for low-latency terminals in the communication system; for high-latency terminals in the communication system, access The network equipment only carries the paging indication corresponding to the high-latency terminal in the synchronization information block. Correspondingly, after the high-latency terminal parses its own paging instruction from the synchronization information block, it obtains the corresponding paging instruction from the access network equipment by beam request. paging message to complete the paging response, which is not limited in this embodiment of the present disclosure.

In order to let the terminal know the timing of receiving the paging signal, on the basis of FIG. 3A , as shown in FIG.

In step 308, the access network device sends system information to the terminal, where the system information carries the PO corresponding to the paging signal, and the PO is determined by the time domain length of the time-frequency resources occupied by the paging signal.

After the terminal enters the cell covered by the access network device, it receives the system information sent by the access network device, and the system information includes the PO corresponding to the paging signal.

Illustratively, as shown in FIGS. 4A to 4C , the PO corresponding to the paging signal is the time domain length of the time-frequency resources occupied by the first to fourth time-frequency resources used to carry the paging signal.

In step 309, the terminal receives the system information sent by the access network device.

Optionally, after receiving the system information sent by the access network device, the terminal obtains the PO contained in the system information, and configures a receiving window (ie, wake-up duration) according to the size of the PO, where the receiving window is larger than the PO.

In step 301, the access network device generates a paging signal.

In step 302, the access network device simultaneously transmits a paging signal to the terminal using n scanning beams on n subbands, where n is a positive integer greater than 1.

In step 310, the terminal receives the paging signal sent by the access network device according to the PO.

Optionally, the terminal receives the paging signal sent by the access network device according to the configured receiving window, that is, the terminal keeps an awake state during the receiving window, and receives the paging signal sent by the access network device through beam scanning.
