Description

Paging signal sending method, paging signal receiving method, device and system

The present application claims priority of international patent application with application number PCT/CN2017/070474, entitled "paging signal sending method, paging signal receiving method, device and system", filed in 2017 on 6.1.2017, the entire contents of which are incorporated herein by reference.

Technical Field

The disclosed embodiments relate to the field of communications, and in particular, to a paging signal sending method, a paging signal receiving method, an apparatus, and a system.

Background

In a Long-Term Evolution (LTE) system, a base station periodically transmits a Paging Indication (Paging Indication) to a terminal in a cell by using an omni-directional transmission technology, so that the terminal in a dormant state acquires a corresponding Paging message from the base station after receiving the Paging Indication in a Discontinuous Reception (DRX) cycle.

In the fifth generation mobile communication technology (5G) system, the base station and the terminal may use a high frequency band above 6GHz, and in order to solve the problem of poor coverage and large attenuation of high frequency signals, the base station may transmit signals to the terminal in a beam scanning manner. For example, when the base station transmits a paging signal to a terminal in a cell in a beam scanning manner, the base station completes scanning of the entire cell by changing a beam direction of a scanning beam. The time length required by the base station to completely scan the cell for one week is one beam scanning period. The terminal wakes up once every other DRX period, and in order to ensure that the terminal can receive the scanning beam in time, the terminal needs to configure a wake-up duration which is greater than or equal to one beam scanning period, so that the wake-up duration of the terminal is longer, and the power saving of the terminal is not facilitated.

Referring to fig. 1, a schematic structural diagram of a mobile communication system according to an embodiment is shown. The mobile communication system may be a 5G system, which is also called a New Radio (NR) system. The mobile communication system includes: access network device 120 and terminal 140.

Access network device 120 may be a base station. For example, the base station may be a base station in a 5G system that employs a centralized distributed architecture, such as a gNB. When the access network device 120 adopts a centralized distributed architecture, it generally includes a Centralized Unit (CU) and at least two Distributed Units (DUs). A Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, and a Media Access Control (MAC) layer are provided in the central unit; a Physical (PHY) layer protocol stack is disposed in the distribution unit, and a specific implementation manner of the access network device 120 is not limited in the embodiment of the present disclosure. Access network device 120 further includes a transceiver, which is a Multiple-Input Multiple-Output (MIMO) antenna supporting beamforming, and optionally, the transceiver is a TRP-like beam scanning node.

The access network device 120 and the terminal 140 establish a wireless connection over a wireless air interface. Optionally, the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a New Radio (NR); alternatively, the wireless air interface may be a wireless air interface based on a 5G next generation mobile communication network technology standard.

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

It should be noted that, in the mobile communication system shown in fig. 1, a plurality of access network devices 120 and/or a plurality of terminals 140 may be included, and fig. 1 illustrates one access network device 120 and one terminal 140, but this embodiment is not limited thereto.

In a 5G system, an access network device and a terminal will use a high-frequency band above 6GHz, however, in the high-frequency band, attenuation of a high-frequency signal is large, and thus coverage of the high-frequency signal is small. In order to solve the problem of poor coverage and large attenuation of high-frequency signals, in the 5G system, the access network equipment transmits the high-frequency signals to the terminals in the managed cell by adopting a beam scanning mode.

In the related art, in order to implement beam scanning, an access network device sets a beam scanning node such as a Transmission Reception Point (TRP) for a managed cell, transmits a scanning beam using the beam scanning node, and then completes beam scanning of the entire cell by changing a beam direction of the scanning beam. For example, as shown in fig. 2 (a), when the access network device 220 transmits a paging signal to the terminal 240 in the cell by using a beam scanning method, the access network device scans clockwise for one circle (the beam direction of the scanning beam 221 is continuously changed) with the illustrated position as a scanning start point, that is, the scanning of the whole cell is completed. As shown in fig. 2 (b), in the time domain (t) -frequency (f) coordinate axis, the time-frequency unit corresponding to each square indicates a scanning beam containing a paging signal, and the beam direction of the scanning beam corresponding to each square is different, so that the beam scanning period required for the access network device to completely scan a circle is 16 time-domain units.

When the terminal 240 wakes up from the DRX cycle and receives a paging signal belonging to itself, it responds to the paging signal, thereby completing the entire paging procedure. However, if the terminal 240 wakes up from the DRX cycle and the scanning beam 221 just sweeps over the terminal 240, the terminal 240 needs to keep the awake state until the next scanning cycle to receive the paging signal in time, so that the terminal 240 needs to keep the longer awake state (the awake duration is greater than or equal to one beam scanning cycle, i.e. greater than or equal to 16 time domain units) in each DRX cycle, which is not favorable for terminal power saving.

Referring to fig. 3A, a flowchart of a method for sending a paging signal according to an embodiment is shown. The present embodiment is exemplified by applying the paging signal transmission method to the mobile communication system shown in fig. 1. The method comprises the following steps:

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 message (Paging). The paging indication is used for indicating whether the terminal is paged, and the paging message contains information such as calling party identification and paging time.

Optionally, the paging signal generated by the access network device is carried inside a synchronization information Block (SS Block), or after the synchronization information Block, so that the terminal further responds to paging according to the paging signal after completing synchronization according to the synchronization signal in the synchronization information Block.

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

The terminal is a general finger and is used for indicating at least one terminal.

After the access network equipment generates the paging signal, the paging signal is expanded to n sub-bands, and the paging signal is sent to the terminals in the covered cell by adopting the scanning wave beam on each sub-band. Optionally, the n subbands are consecutive n subbands.

Optionally, the beam scanning areas of the scanning beams corresponding to each sub-band are different, and a set of the beam scanning areas of the respective scanning beams is a range of a cell covered by the access network device. Illustratively, the beam scanning area of the scanning beam corresponding to each sub-band occupies 1/n of the coverage area of the access network device.

For example, as shown in fig. 3B (a), the paging signal is spread over 4 subbands, and the scanning beams corresponding to the subbands are the first scanning beam 321, the second scanning beam 322, the third scanning beam 323, and the fourth scanning beam 324, respectively. The first scanning beam 321 corresponds to the beam scanning area 1 (90 ° sector area at the upper right corner), the second scanning beam 322 corresponds to the beam scanning area 2 (90 ° sector area at the lower right corner), the third scanning beam 323 corresponds to the beam scanning area 3 (90 ° sector area at the lower left corner), and the fourth scanning beam 324 corresponds to the beam scanning area 4 (90 ° sector area at the upper left corner), that is, the beam scanning area of each scanning beam occupies 1/4 of the complete beam scanning area.

Because the coverage area of a single scanning beam is limited, in order to achieve complete coverage of each beam scanning area, the access network device needs to continuously change the scanning direction of the scanning beam on each sub-band. That is, for the same beam scanning area, the access network device may use different scanning beams to scan the current beam scanning area in different time domain units, but use one scanning beam to scan the current beam scanning area in the same time domain unit.

Optionally, the scanning direction of the scanning beam on each sub-band is the same. For example, as shown in fig. 3B (a), 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, the scanning end position of the ith scanning beam is coincided with the boundary of the sector beam scanning area corresponding to the (i + 1) th scanning beam in the n scanning beams, and i is less than n; the scanning end position of the ith scanning beam is overlapped with the boundary of the sector beam scanning area corresponding to the 1 st scanning beam, and i is equal to n.

Since 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 used by the access network device in fig. 2. Illustratively, as shown in fig. 3B (B), the access network device simultaneously performs beam scanning on 4 scanning beams on 4 subbands, and when each subband needs 4 time domain units to completely scan its respective beam scanning area, the access network device needs 4 time domain units in total to implement the complete beam scanning on the covered cell, and compared with the access network device in fig. 2 (B), the access network device needs 16 time domain units to perform the complete beam scanning on the covered cell, and a beam scanning period is reduced to 1/4.

It should be noted that, a time domain unit required by a subband to completely scan a beam scanning region is related to the size of the range of the beam scanning region, the larger the range of the beam scanning region is, the longer the time domain unit required by the subband to completely scan the beam scanning region is, the smaller the range of the beam scanning region is, and the smaller the time domain unit required by the subband to completely scan the beam scanning region is, this embodiment only takes 4 time domain units required for completely scanning the beam scanning region as an example to describe, and does not limit the present disclosure.

When the paging signal is sent to the terminal in the cell by adopting the mode, the paging time delay of the terminal is reduced because the wave beam scanning period is reduced to 1/n; correspondingly, the awakening time length configured by the terminal is also reduced to the original 1/n, namely the terminal can be in a longer dormant state, and the power saving of the terminal is facilitated.

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

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

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

Optionally, after receiving the paging signal, the terminal determines whether there is a paging message according to the paging indication in the paging signal, and if there is a paging message, the terminal acquires a corresponding paging message from the paging signal and responds to the paging message; if the paging does not exist, the terminal discards the paging signal and enters a dormant state.

To sum up, in the paging signal transmitting method provided by the embodiment of the present disclosure, after the access network device generates a paging signal, the access network device simultaneously transmits the paging signal to the terminal by using n scanning beams with different scanning areas of the n sub-band upper beams, so as to reduce the transmission delay of the paging signal; meanwhile, the wave beam scanning period required by the access network equipment for completely scanning the covered cell is reduced, so that the awakening time configured by the terminal is reduced, the time for the terminal to be in a dormant state is increased, and the power saving of the terminal is facilitated.

It should be noted that, steps 301 and 302 may be implemented as an embodiment of a paging signal transmission method on the access network device side, and step 303 may be implemented as an embodiment of a paging signal reception method on the terminal side, which is not limited in this embodiment.

In the foregoing embodiment, the access network device sends the paging signal to the terminal by using 4 scanning beams on 4 subbands at the same time, and optionally, the number n of the subbands and scanning beams used when the access network device sends the paging signal is determined by the number of TRPs, and/or determined by the number of terminals located in a cell covered by the access network device. Wherein 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 when the access network device sends the paging signal is proportional to the number of TRPs, that is, the more TRPs are set in the access network device, the more subbands and scanning beams can be used when the access network device sends the paging signal, and accordingly, the smaller the beam scanning area corresponding to each scanning beam is, and the smaller the beam scanning period required for the access network device to completely scan the covered cell is.

For example, when the access network device is provided with 4 TRPs, the access network device may simultaneously transmit a paging signal to the terminal on 4 subbands by using 4 scanning beams, where a beam scanning area corresponding to each scanning beam is a 90 ° sector area; when the access network device is provided with 3 TRPs, the access network device may simultaneously transmit a paging signal to the terminal on 3 subbands by using 3 scanning beams, where a beam scanning area corresponding to each scanning beam is a 120 ° sector area.

In another possible implementation, the access network device determines the number of sub-bands and scanning beams to be used according to the number of terminals in the coverage area of the cell. Optionally, when the number of terminals in the covered cell range is smaller than the preset number, the access network device uses a part of TRPs to transmit paging signals on corresponding subbands, thereby reducing power consumption on the premise of ensuring paging quality; when the number of terminals in the covered cell range is larger than the preset number, the access network equipment uses all TRPs to send paging signals on corresponding sub-bands, thereby reducing paging time delay and improving paging quality.

Optionally, the access network device further determines the number of the adopted sub-bands and scanning beams according to the time delay requirement of the terminal in the cell. For example, when the delay requirement of the terminal in the cell is lower than the predetermined delay requirement (i.e. the terminal is a low-delay-requirement terminal), the access network device uses part of the TRP to transmit the paging signal on the corresponding subband, thereby reducing power consumption on the premise of ensuring paging quality; when the delay requirement of the terminal in the cell is higher than the preset delay requirement (namely the terminal is a high-delay-requirement terminal), the access network equipment uses all TRPs to send the paging signal on the corresponding subband, thereby reducing the paging delay and improving the paging quality.

In a possible implementation, each subband includes m synchronization information blocks located in m consecutive time domain units, and the synchronization information blocks carry synchronization signals, and the paging signals generated by the access network device are carried in the synchronization information blocks.

Illustratively, for any one of the 4 subbands shown in (B) of fig. 3B, as shown in fig. 4A, the subband includes 4 synchronization information blocks 40 located in 4 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, the terminal performs synchronization first according to the synchronization signal 41 in the synchronization information block 40 and then performs paging response according to the paging signal 43.

In other possible embodiments, as shown in fig. 4B, the paging signal 43 is carried in each synchronization information block 40, and the time domain positions of the paging signal 43 and the synchronization signal 41 and the broadcast signal 42 are the same, i.e. the synchronization signal 41, the broadcast signal 42 and the paging signal 43 are distributed in different frequency domain positions of 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 a first terminal (i.e. a narrow bandwidth terminal) that does not support a preset frequency band, since a frequency band supported by the first terminal is the same as a frequency band of a synchronization information block, when a first time-frequency resource carries a paging signal corresponding to the first terminal, the first terminal can receive a corresponding paging signal on the first time-frequency resource; for a second terminal (i.e. a wideband terminal) supporting a preset frequency band, since the frequency band supported by the second terminal is greater than the frequency band of the synchronization information block, when the first time-frequency resource carries a 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 predetermined frequency band is set according to a communication standard.

Therefore, the access network device can adopt the mode 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, so that the narrow bandwidth terminal and the broadband terminal can acquire the paging signals from the synchronization information block, and the reliability of receiving and transmitting the paging signals is improved.

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 signals increases. Under the condition of larger paging quantity, the beam scanning period of the access network equipment is also increased, which results in the increase of the time delay of the paging signal, and correspondingly, the terminal needs to keep a longer wake-up state to receive the paging signal.

To solve the above problem, in one possible implementation, as shown in fig. 4C, the paging signal 43 occupies a first time-frequency resource 431 and a second time-frequency resource 432 on a subband. The frequency band of the first time-frequency resource 431 is smaller than or larger than the frequency band of the second time-frequency resource 432, the first time-frequency resource 431 is continuous with the second time-frequency resource 432, the frequency band of the first time-frequency resource 431 belongs to the frequency band of 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 embodiments, the frequency bands of the first time-frequency resource 431 and the second time-frequency resource 432 are not consecutive, 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 limited in this disclosure.

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 for carrying 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 second terminal.

Optionally, the access network device sends the resource position of the first time-frequency resource to the first terminal and the second terminal through Minimum System Information (Minimum SI), and correspondingly, the first terminal and the second terminal receive the Minimum System Information, so as to obtain the paging signal carried in the first time-frequency resource according to the resource position carried in the Minimum System Information; meanwhile, in order to enable the second terminal supporting the broadband to acquire the paging signal carried in the second time-frequency resource, the access network device sends the resource location of the second time-frequency resource to the second terminal through Other System Information (Other SI), and correspondingly, the second terminal receives the Other System Information and acquires the resource location of the second time-frequency resource carried in the Other System Information.

Optionally, when 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 when there is a vacancy in the first time-frequency resource 431, carries a part of the paging signal corresponding to the second terminal in the first time-frequency resource 431, and carries the remaining part of the paging signal corresponding to the second terminal in the second time-frequency resource 432.

Correspondingly, the first terminal acquires the paging signal from the first time-frequency resource on the sub-band, and the second terminal acquires the paging signal from the first time-frequency resource and/or the second time-frequency resource on the sub-band.

In one possible implementation, as shown in fig. 4D (a), when the Paging signal includes a Paging indicator and a Paging message, the access network device carries a Paging indicator PI 1 and a Paging message Paging 1 of the first terminal on the first time-frequency resource 431, and carries a Paging indicator PI 2 and a Paging message Paging 2 of the second terminal on the second time-frequency resource 432.

In another possible implementation, because the time-frequency resource occupied by the Paging indicator is much smaller than the time-frequency resource occupied by the Paging message, as shown in (b) of fig. 4D, the access network device carries the Paging indicator PI 1 and the Paging message Paging 1 of the first terminal and the Paging indicator PI 2 of the second terminal on the first time-frequency resource 431, and carries the Paging message Paging 2 of the second terminal on the second time-frequency resource 432.

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 time domain of the time-frequency resources carrying the paging signal; compared with the paging signal carrying mode shown in fig. 4A, in the case of a large paging amount, the beam scanning period of the access network device is small, the time delay of the paging signal is small, and accordingly, the terminal only needs to keep a short time of wake-up state to receive the paging signal, which is beneficial to saving power of the terminal.

In the paging signal carrying manners shown in fig. 4A to 4C, the time-frequency resources (including the first time-frequency resources and/or the second time-frequency resources) carrying the paging signal are all located inside the synchronization information block, that is, the paging signal and the synchronization information block are transmitted simultaneously. Under the condition of sparse paging, the access network equipment carries paging signals every time when sending the synchronous information block, which causes time-frequency resource waste.

In order to avoid the time-frequency resource waste, in another possible implementation, the paging signal is carried in m time-frequency resources located after the time domain positions of the m synchronization information blocks, and each i groups of m synchronization information blocks correspond to 1 group of m time-frequency resources, where 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 4 synchronization information blocks 40.

The first time-frequency resource 431 is used for carrying a paging signal corresponding to the first terminal and/or the second terminal, and the second time-frequency resource 432 is only used for carrying a paging signal corresponding to the second terminal. The specific carrying manner is similar to that shown in fig. 4C, and the description of this embodiment is omitted here.

Optionally, when the paging signal carrying 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, 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 on the n subbands by using n first scanning beams.

And aiming at each sub-band in the n sub-bands, the access network equipment adopts a first scanning beam to send the synchronization signals and the broadcast signals carried on the m synchronization information blocks to the terminal on the sub-band.

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

Correspondingly, the terminal receives the synchronization signal and the broadcast signal which are sent by the access network equipment and are carried on the m synchronization information blocks on the sub-band, so that the synchronization is carried out according to the synchronization signal.

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

In a possible implementation manner, when paging is frequent in the system, after the access network device uses the first scanning beam to transmit a synchronization signal and a broadcast signal (carried on a synchronization information block), that is, n second scanning beams are enabled on n subbands to transmit a paging signal carried on a time-frequency resource to the terminal, that is, after each group of synchronization information blocks is transmitted by the access network device, a group of paging signals is transmitted;

when paging is sparse in the system, the access network equipment adopts the first scanning beam to send i groups of m synchronous information blocks to the terminal, and then starts the second scanning beam to send paging signals loaded on m time-frequency resources to the terminal on n subbands, namely the access network equipment sends a group of paging signals after sending the i groups of synchronous information blocks, thereby avoiding time-frequency resource waste caused by frequently sending the paging signals when the paging is sparse.

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

The paging signals carried on the m time-frequency resources are sent by the access network equipment on n subbands by using n second scanning beams. Correspondingly, after receiving the time frequency resource, the terminal responds paging according to the paging signal carried in the time frequency resource.

Obviously, the access network device carries the paging signal after the time domain position of the synchronization information block by using the method shown in fig. 4E, and separately adopts scanning beam transmission, thereby avoiding the time-frequency resource waste caused by the fact that the access network device carries the paging signal every time when sending the synchronization information block under the condition of sparse paging; meanwhile, compared with the bearing mode shown in fig. 4A to 4C, the time domain length occupied by the time-frequency resource bearing the paging signal in fig. 4E is smaller, and the wake-up duration configured by the terminal is correspondingly reduced, thereby further improving the power saving performance of the terminal.

For a low-latency terminal such as a urrlc terminal in a communication system, in order to ensure that the low-latency terminal can respond to a paging signal as soon as possible, in another possible implementation, each sub-band includes m synchronization information blocks located in m consecutive time domain units, and a paging indicator in the paging signal is carried in a time-frequency resource located in each synchronization information block after a time domain position of the synchronization signal, and a paging message in the paging signal is carried in m time-frequency resources located in m time-frequency resources after the time domain position of the m synchronization information blocks.

Illustratively, as shown in fig. 4G, each subband includes 4 synchronization information blocks 40 located in 4 consecutive time domain units, and each synchronization information block 40 carries a synchronization signal 41 and a broadcast signal 42. When the access network equipment sends the paging signal, the paging indication 44 in the paging signal is carried in the time-frequency resources after the time domain position of the synchronization signal 41, and the paging message 45 in the paging signal is carried in 4 time-frequency resources after the time domain positions of the 4 synchronization information blocks 40.

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

In step 303A, the terminal detects whether a paging indicator corresponding to the terminal is carried in the synchronization information block.

For a uRLLC terminal in a communication system, after receiving a synchronization information block sent by an access network device on a sub-band, the terminal analyzes the synchronization information block and further detects whether the terminal contains a paging indication of the terminal. If the paging instruction containing the paging instruction is detected, executing the following

steps

303B and 303C to further acquire a corresponding paging message; if it is detected that the paging indicator does not include the paging indicator, the following step 303D is performed.

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

When detecting that the synchronization information block carries its paging indication, the terminal knows that there is its paging message in the following, and in order to ensure that the paging message can be received in time, the terminal needs to remain in an awake state after receiving the synchronization information block. Therefore, the terminal determines the PO corresponding to the paging signal as the first time domain length, i.e. the PO is kept awake within the first time domain length, thereby ensuring that the paging messages carried in m time-frequency resources after m synchronization information blocks are obtained in time.

Illustratively, as shown in fig. 4G, when detecting that the synchronization information block carries its own paging indicator, the terminal determines that the PO is the sum of the 4 synchronization information blocks 40 and the time domain lengths corresponding to 4 time-frequency resources after the synchronization information blocks 40.

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

Further, the terminal keeps the awakening state under the PO, and obtains the paging messages carried in m time-frequency resources behind the synchronous information block, thereby completing paging according to the paging messages of the terminal.

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, where the second time domain length is the time domain length corresponding to the m synchronization information blocks.

When detecting that the synchronization information block does not carry the paging indication of the terminal, the terminal knows that no paging message of the terminal exists subsequently, and determines the PO corresponding to the paging signal as the time domain length (i.e. the second time domain length) corresponding to the m synchronization information blocks, so that the terminal enters a sleep state after receiving the m synchronization information blocks, and the effect of saving power is achieved.

Optionally, the access network device only configures m time-frequency resources (carrying paging messages) after the time domain position of the synchronization information block for the low-latency terminal in the communication system; for a high-latency terminal in a communication system, an access network device only carries a paging indication corresponding to the high-latency terminal in a synchronization information block, and correspondingly, after the high-latency terminal resolves the paging indication of itself from the synchronization information block, the high-latency terminal acquires a corresponding paging message from the access network device in a beam request manner, thereby completing a paging response.

In order to make the terminal know the timing of receiving the paging signal, on the basis of fig. 3A, as shown in fig. 4I, step 301 is preceded by steps 308 and 309, and step 303 is replaced by step 309.

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

And after entering a cell covered by the access network equipment, the terminal receives system information sent by the access network equipment, wherein the system information comprises PO corresponding to the paging signal.

Schematically, as shown in fig. 4A to 4C, PO corresponding to the paging signal is the time domain length of the time frequency resource occupied by the 1 st to 4 th time frequency resources for carrying 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 included in the system information, and configures a receiving window (i.e., an awake duration) according to the size of the PO, where the receiving window is greater than the PO.

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

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

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