Computer instructions may be stored in or transmitted from one computer-readable storage medium to another computer-readable storage medium, e.g. Coaxial cable, optical fiber, digital subscriber line (DSL)) or wireless (such as infrared, wireless, microwave, etc.) to another website site, computer, server or data center.

Based on the above mobile terminal hardware structure and communication network system, various embodiments of the present application are proposed.

FIG. 5 is a schematic diagram of a paging cycle provided by an embodiment of the present application. As shown in FIG. 5 , the paging cycle of a terminal device is 320 ms. In each paging cycle, including a paging moment, the terminal device is woken up at the paging moment of each paging cycle, and listens to the paging radio network temporary identity (P-RNTI) scrambling PDCCH to obtain paging messages.

In Fig. 5, a paging advance indication information is also illustrated, and the paging advance indication information is used to indicate whether there is paging message transmission at the current paging occasion (only one paging advance indication information is illustrated in Fig. 5 , in actual Before the start of each paging opportunity (PO), the network device may send a paging advance indication information to indicate whether there is a paging message transmission for the corresponding paging opportunity). If yes, the terminal device is woken up, and monitors the paging message; and/or, if not, does not monitor the paging message.

In some implementations, due to the different traffic volumes of different terminal devices, taking a light-capable device as an example, the light-capable device may interact with the network device at a relatively long interval, such as a few seconds or a few minutes. Even hours. If the paging cycle is 320 ms, the terminal device needs to be woken up and monitor the PDCCH every 320 ms, so that the light-capable device consumes a lot of power.

Based on the above technical problems, an embodiment of the present application provides a solution for updating a paging cycle, so as to reduce power consumption of a terminal device.

FIG. 6 is a signaling diagram of a paging cycle update method provided in an embodiment of the present application. As shown in FIG. 6, the method may include:

S61. The network device sends indication information modulated in an on-off keying manner, where the indication information is used to instruct a terminal device in an idle state or an inactive state to update a paging cycle.

The terminal device in the embodiment of this application can be a common device or a light-capable (RedCap) device. The light-capable device can include household appliances such as refrigerators, TVs, and air conditioners, and can include wearable devices such as smart watches and sports bracelets, for example. wait. The device's bandwidth, data rate, etc. are different from ordinary devices.

Optionally, the terminal device may be in an RRC idle state; optionally, the terminal device may be in an RRC inactive state, and the inactive state may also be referred to as an inactive state.

The terminal device determines the paging occasion according to its own UE_ID and paging cycle. After the paging occasion is determined, the terminal device is woken up regularly at the paging occasion, and monitors whether there is a paging message at the current paging occasion.

For example, if the current paging cycle is 1280ms, the terminal device will wake up every 1280ms to monitor whether there is a paging message.

Optionally, when the network device sends the indication information to the terminal device, it modulates the indication information by using the OOK modulation mode to obtain the indication information modulated by the OOK modulation mode. Usually, the indicator information is modulated by quadrature phase shift keying (Quadrature Phase Shift Keying, QPSK), 16 quadrature amplitude modulation (16QAM), 64QAM and other modulation methods. A high-power receiver is required, resulting in relatively large power consumption of the receiver of the terminal device. Based on this, the embodiment of the present application provides an on-off keying (On-Off Keying, OOK for short) modulation method for sending indication information.

Fig. 7 is a schematic diagram of the instruction information modulation process provided by the embodiment of the present application, as shown in Fig. 7, including:

S71. The network device encodes and interleaves binary bits related to the indication information.

S72. The network device performs OOK modulation on the coded and interleaved binary bits.

S73. The network device performs inverse fast Fourier transform (Inverse Fast Fourier Transform, IFFT for short) and cyclic prefix (Cyclic Prefix, CP for short) insertion processing on the OOK-modulated indication information to obtain a modulated signal.

S74. The network device sends the modulated signal to the terminal device through the antenna.

The OOK modulation method is a binary modulation, which uses a unipolar non-return-to-zero code sequence to control the on and off of the sinusoidal carrier. The modulation principle is to control one amplitude to be 0 and the other to be non-zero. Alternatively, a logical 1 is represented by sending a signal (ON), and a logical 0 is represented by not sending a signal (OFF).

Optionally, when sending the indication information to the terminal device, the network device first modulates the indication information based on an on-off keying manner to obtain a modulated signal, and then sends the modulated signal to the terminal device. Correspondingly, after receiving the modulated signal, the terminal device demodulates the modulated signal to obtain the indication information. Compared with QPSK, 16QAM, 64QAM and other modulation methods, the OOK modulation method is used to modulate the indication information, which can reduce the power of the terminal device when receiving the indication information, and save the power consumption of the receiver of the terminal device.

S62. The terminal device receives the indication information modulated in the on-off keying mode.

After the network device sends the indication information, the terminal device receives the indication information, where the indication information is used to instruct the terminal device to update the paging cycle.

Optionally, the indication information may instruct the terminal device to update the paging cycle to a longer paging cycle, or may instruct the terminal device to update the paging cycle to a shorter paging cycle.

Optionally, the indication information may instruct the terminal device to update the paging cycle to another specific paging cycle, that is, the network device indicates the updated paging cycle. For example, the indication information may instruct the terminal device to update the duration of the paging cycle to be N times the duration of the current paging cycle, where N is a positive number. For example, the indication information may indicate the duration of the target paging cycle, and the terminal device updates the paging cycle to the target paging cycle according to the indication of the indication information, and so on.

S63. The terminal device updates the paging cycle of the terminal device according to the indication information.

After receiving the indication information, the terminal device may update the paging cycle of the terminal device according to the indication information.

Optionally, if the indication information instructs the terminal device to update the paging cycle to another specific paging cycle, the network device indicates the updated paging cycle through the indication information. The terminal device may switch to the paging cycle indicated by the network device according to the indication information. The duration of the updated paging cycle may be longer than the current paging cycle of the terminal device, may also be shorter than the current paging cycle of the terminal device, and may also be equal to the current paging cycle of the terminal device.

Optionally, before the network device sends the indication information to the terminal device, the network device may determine that the paging cycle of the terminal device needs to be updated based on the current service load. Optionally, the current service load may be, for example, the frequency at which the terminal device transmits data, for example, it may be the number of terminal devices accessing the network.

When the current service load includes the frequency of data transmission by terminal equipment, a frequency threshold range can be preset, and according to the frequency threshold range and the frequency of data transmission within a certain period of time, it is judged whether a paging cycle is required update. For example, when the frequency of data transmission is greater than or equal to the first threshold within a certain period of time, the network device determines that the paging cycle of the terminal device needs to be updated; When the value is less than or equal to the second threshold, the network device determines that the paging cycle of the terminal device needs to be updated, and so on.

A specific example will be used to illustrate. The optional value of the duration of the current paging cycle is any one of 2560ms, 1280ms, 640ms and 320ms, and the transmission frequency of the current service is within the range of 1280ms to 2560ms. Optionally, the value of the first threshold is 1280ms, and the current paging cycle of the terminal device is 320ms. At this time, the transmission frequency of the current service is greater than or equal to the first threshold, and the network device determines that the paging cycle of the terminal device needs to be updated, for example The paging cycle of the terminal device can be updated to 1280ms. Optionally, the value of the second threshold is 5120ms. At this time, the transmission frequency of the current service is less than or equal to the second threshold, and the network device determines that the paging cycle of the terminal device needs to be updated. For example, the paging cycle of the terminal device can be updated as 1280ms.

When the current service load includes the number of terminal devices accessing the network, the network device can compare the number of terminal devices currently accessing the network with a preset threshold, so as to determine whether to update the paging cycle. For example, when the number of terminal devices currently accessing the network is greater than or equal to the third threshold, the network device determines that the paging cycle of the terminal devices needs to be updated; When the threshold is reached, the network device determines that the paging cycle of the terminal device needs to be updated, and so on.

A specific example will be used to illustrate. The current maximum number of paging terminal devices allowed by the network at one moment is 64, so the third threshold may be set to 64. When the number of terminal devices is greater than or equal to the third threshold 64, the network device determines to update the paging cycle. By shortening the paging cycle, more than 64 terminal devices can be allocated in multiple paging cycles. For example, when the number of terminal devices is 70 and the paging cycle is 5120ms, you can update the paging cycle to 2560ms, so that some terminal devices are placed in the previous 2560ms paging cycle, and other part of the terminal devices are placed in the paging cycle. In the next 2560ms paging cycle. When the number of terminal devices is small, a fourth threshold may be set. For example, the fourth threshold is set to be 4, and when the number of terminal devices is less than or equal to 4, the network device determines that the paging cycle of the terminal devices needs to be updated. For example, the current paging cycle is 320ms, and when the number of terminal devices is less than or equal to the fourth threshold 4, the paging cycle is updated from 320ms to 5120ms.

When the network device determines that the paging cycle of the terminal device needs to be updated, the network device may instruct the terminal device to update the paging cycle by sending indication information to the terminal device.

Optionally, when the indication information belongs to the reference signal, the indication information is a channel state information reference signal (CSI-RS), a primary synchronization signal (Primary Synchronization Signal, PSS), a secondary synchronization signal (Secondary Synchronization Signal, PSS), ZC sequence (Zadoff-Chu sequence), at least one of the M sequence.

Optionally, when the indication information belongs to DCI, the indication information is paging advance indication information, or other DCIs occupying channel control resources except the paging advance indication information.

When the indication information belongs to the reference signal or DCI, it is convenient for the terminal equipment to obtain the paging cycle information through corresponding detection at a specified time. Compared with the way of updating the paging cycle through RRC signaling or system messages, the reference signal or DCI The way of updating the paging cycle is more flexible. Further, the method of updating the paging cycle by using the reference signal or DCI occupies less time-frequency resources, which can enable the terminal device to obtain a longer sleep time or a shorter time paging response with a small system cost.

Optionally, the indication information may include a short message indication, and the short message indication is used to indicate that the paging occasion includes a short message and/or paging information. If the short message indicates that only short messages are included in the paging occasion, then the corresponding paging occasion only needs to continue paging the short message in the PDCCH; and/or, if the short message indicates that only paging information is included in the paging occasion, or, The short message indicates that the paging occasion includes the paging information and the short message, and the terminal device needs to connect to the paging PDCCH and the paging PDSCH corresponding to the paging occasion.

Optionally, the indication information includes a paging identifier, and the paging identifier may include an identifier of a terminal device or an identifier of a paging group.

Optionally, the indication information includes the identification of the terminal device and/or paging advance indication information, and the terminal device receives the identification of the terminal device and/or paging cycle update information from the network device, and then according to the identification of the terminal device and/or The paging cycle update information updates the current paging cycle of a specified single terminal device to the target paging cycle.

Optionally, the indication information may include an identifier of the paging group and/or paging advance indication information. Multiple terminal devices can be determined as a paging group, and multiple terminal devices in a paging group can have the same paging cycle. All terminal devices in the paging group can receive the paging group identifier and/or paging cycle update information from the network device, and then update the current paging cycle to The target paging cycle is used to update the paging cycle of the paging group.

Optionally, if the identifier of the paging group is the group number of the paging group, it indicates that any terminal device in the paging group needs to set the current paging cycle as the target paging cycle.

Optionally, the group number to which the terminal device belongs can be represented by H, which is determined by formula (1):

H＝UE_ID mod G formula (1)

Among them, G represents the number of groups. UE_ID represents the identifier of the terminal equipment.

For example, if there are 5 groups of terminal devices, then G=5. Among them, the group number H of the first group can be 0, the group number H of the second group can be 1, the group number H of the third group can be 2, the group number H of the fourth group can be 3, and the group number H of the fifth group can be 3. The group number H can be 4. For example, if the UE_ID of UE1 is 5, H=0 can be calculated by formula (1), and UE1 can be divided into the first group; if the UE_ID of UE2 is 16, H=0 can be calculated by formula (1). 1, then UE2 can be divided into the second group; if the UE_ID of UE3 is 7, then H=2 can be calculated by formula (1), then UE3 can be divided into the third group; if the UE_ID of UE4 is 23, then It can be calculated by formula (1) to get H=3, then UE4 can be divided into the fourth group; if the UE_ID of UE5 is 39, it can be calculated by formula (1) to get H=4, then UE5 can be divided into the fifth group Group.

Optionally, the group number to which the terminal device belongs may also be specified by the network side, and sent to the terminal device through high-layer signaling.

For example, if the paging identifier is H=0, and the paging group whose group number is H=0 includes 3 UEs, it can be indicated that the 3 UEs in the paging group need to update the current paging cycle as the target paging cycle. call cycle.

In the example in FIG. 5 , the paging advance indication information is mainly used to indicate whether there is a paging message at one or more paging occasions in the paging cycle.

Optionally, in addition to indicating whether there is a paging message in the paging cycle, the paging advance indication information may also be used as indication information indicating paging cycle update. And it can be used as the indication information for updating the paging cycle, which can be aimed at a single terminal device, or can be aimed at multiple terminal devices in the same paging group.

Next, the update of the paging cycle will be described with reference to FIG. 8A-FIG. 8B.

FIG. 8A is a schematic diagram of updating a paging cycle provided by an embodiment of the present application. As shown in FIG. 8A , it illustrates a manner of instructing a terminal device to update a paging cycle through indication information. In the example of FIG. 8A , the indication information includes the identification of the terminal device and/or paging cycle update information, the network device sends the indication information modulated in OOK mode to the terminal device, the terminal device receives the indication information, and according to the indication information, the The current paging cycle is updated as the target paging cycle. In FIG. 8A , the indication information is introduced as an example of paging advance indication information. In practice, the indication information may also include other implementation manners, such as reference signal forms such as SSS and PSS, or other DCI forms.

The paging advance indication as the paging cycle update indication information can be aimed at a single terminal device, as shown in Figure 8A, if the paging advance indication information includes the identity of UE1, only UE1 will update the paging advance indication information The paging cycle contained in the other terminals that receive the paging advance indication information, because their UE_ID is inconsistent with the terminal identifier contained in the paging advance indication information, so these terminals will not update the paging cycle. In other words, only UE1 updates the paging cycle after receiving the indication information, and other terminals do not update the paging cycle.

FIG. 8B is another schematic diagram of updating the paging cycle provided by the embodiment of the present application. As shown in FIG. 8B , it illustrates a manner of instructing the terminal device to update the paging cycle through indication information. In the example of FIG. 8B , the indication information includes the identity of the paging group and/or paging cycle update information, the network device sends the indication information modulated in OOK mode to the terminal device, the terminal device receives the indication information, and according to the indication information, Update the current paging cycle to the target paging cycle. In FIG. 8B , the indication information is taken as an example to introduce the paging advance indication information. In practice, the indication information may also include other implementation manners, such as reference signal forms such as SSS and PSS, or other DCI forms.

The paging advance indication information used as the paging cycle update indication information may be for the paging group. As shown in FIG. 8B, an example includes 3 UEs in a paging group, namely UE1, UE2 and UE3, and record this The paging group is paging group 1. When the paging identifier included in the paging advance indication information sent by the network device is the identifier of paging group 1, only UE1, UE2 and UE3 in paging group 1 will paging according to the received paging advance indication information. The paging cycle is updated according to the cycle update information, and the terminals in other paging groups receiving the paging advance indication information will not update the paging cycle according to the paging cycle update information in the received paging advance indication information, that is Only the terminals in the paging group included in the paging advance indication information will update the paging cycle.

When the indication information is PEI, PEI can be carried in many different ways, such as carrying PEI through DCI mapping (DCI-based PEI) and carrying PEI through sequence mapping (sequence-based PEI). Optionally, Sequence-based PEI includes carrying PEI through SSS reference signal mapping (SSS-based PEI) and carrying PEI through TRS reference signal mapping (TRS/CSI-RS-based PEI).

The above DCI‐based PEI and sequence‐based PEI are usually modulated by quadrature phase shift keying (Quadrature Phase Shift Keying, QPSK), 16 quadrature amplitude modulation (16QAM), 64QAM and other modulation methods. When performing demodulation, a high-power receiver is required, resulting in relatively large power consumption of the receiver of the terminal device. Based on this, the embodiment of the present application provides an on-off keying (On-Off Keying, OOK for short) modulation method for sending indication information.

Optionally, when the network device sends the indication information to the terminal equipment or the paging group, it first modulates the indication information based on the on-off keying method to obtain a modulated signal, and then sends the indication information to the terminal equipment or the terminal equipment in the paging group. the modulated signal. Correspondingly, the terminal device or the terminal devices in the paging group can obtain the indication information by demodulating the modulated signal after receiving the modulated signal.

In the above embodiments, the manner of receiving the indication information is introduced, and the update of the paging cycle performed by any terminal device according to the indication information will be introduced below.

After receiving the indication information, the terminal device updates the current paging cycle of the terminal device to the target paging cycle according to the indication information. The current paging cycle is the paging cycle before the terminal device is updated, and the target paging cycle is the paging cycle after the terminal device is updated. The terminal device may determine the target paging cycle through the indication information. Optionally, the indication information includes paging cycle update information, and the terminal device determines the target paging cycle according to the paging cycle update information.

Optionally, the value of the target paging cycle indicated by the paging cycle update information may include the following two methods:

Mode 1. The paging cycle update information may indicate that the value of the target paging cycle is a certain value in the set of optional values. For example, the set of optional values can be {1,2,4,8,16,32,64,128,256,512,1024}. The unit of the optional value set can be a symbol, or a time slot, or a radio frame. In this manner, the value of the target paging cycle does not need to be determined depending on the value of the current paging cycle.

Optionally, the optional value set may be determined by the network device according to different service types, and indicate to the terminal device which optional value set the current paging cycle belongs to through high-level information.

For example, if the service type is Ultra Reliable & Low Latency Communication (URLLC) service, the set of optional values is {1,2,4,8,16,32,64,128,256,512,1024}.

For example, if the service type is enhanced Mobile Broadband (eMBB) or massive Machine Type of Communication (mMTC) service, the optional value set {1,2,3, 4,5,8, 16, 32, 64, 128, 256}.

Optionally, the unit of the optional value set may also be determined by the network device according to different service types, and indicate to the terminal whether the unit of the optional value set is a symbol, a time slot or a radio frame through high-level information.

For example, if the service type is Ultra Reliable & Low Latency Communication (URLLC) service, the network device can indicate its optional value set as {1,2,4,8,16, 32,64,128,256,512,1024}, and the high-level information indicates that the unit of the optional value set is time slot, then if the target paging cycle of the terminal device is configured as the value "4" in the optional set, it means its target paging cycle for 4 time slots.

For example, if the service type is enhanced Mobile Broadband (eMBB) or massive Internet of Things (massive Machine Type of Communication, mMTC) service, the network device can indicate that its optional value set is {1,2, 3, 4, 5, 8, 16, 32, 64, 128, 256, 512, 1024}, and the higher layer information indicates that the unit of the optional value set is a radio frame. Then, if the target paging cycle of the terminal is configured as the value "64" in the optional set, it means that its target paging cycle is 64 radio frames.

It should be noted that the numerical values in the above optional value set are all examples and do not constitute limitations on actual values.

Mode 2. The paging cycle update information may indicate that the target paging cycle is N times the current paging cycle, where N is a positive number.

When N is a positive number less than or equal to 1, the duration of the updated target paging cycle is less than or equal to the current paging cycle before updating. For example, when N is 1/2, the duration of the target paging cycle is half of the duration of the current paging cycle; when N is 1/3, the duration of the target paging cycle is one-third of the duration of the current paging cycle One, and so on.

Optionally, when N is a positive number less than or equal to 1, N can be (1/2) ^k , k is a natural number, and the value of k can be, for example, 0, 1, 2, 3,..., corresponding Yes, the value of N can be 1, 1/2, 1/4, 1/8,.... Taking the current paging cycle as 2560 ms as an example, when N is 1, 1/2, 1/4, and 1/8 respectively, the target paging cycles are 2560 ms, 1280 ms, 640 ms, and 320 ms respectively. When the value of the current paging cycle is other values, the value of the target paging cycle can be correspondingly determined according to the value of N.

When N is a positive number greater than 1, the duration of the updated target paging cycle is longer than the current paging cycle before updating. For example, when N is 2, the duration of the target paging cycle is twice the duration of the current paging cycle; when N is 3, the duration of the target paging cycle is three times the duration of the current paging cycle, etc. .

Optionally, when N is a positive number greater than 1, N can be ^2k , k is a natural number, and the value of k can be, for example, 1, 2, 3,..., correspondingly, the value of N can be 2,4,8,.... Taking the current paging cycle as 320ms as an example, when N is 2, 4, and 8 respectively, the target paging cycles are 640ms, 1280ms, and 2560ms respectively. When the value of the current paging cycle is other values, the value of the target paging cycle can be correspondingly determined according to the value of N.

It should be noted that the above values of N, k, and current paging cycle are all examples, and do not constitute limitations on actual values.

FIG. 9 is a schematic diagram 1 of updating a paging cycle provided by an embodiment of the present application. As shown in FIG. 9 , the indication information is paging advance indication information as an example. The terminal device receives the paging advance indication information, and acquires paging cycle update information according to the paging advance indication information. Optionally, the paging cycle update information indicates that the target paging cycle is N times the current paging cycle.

In the example in FIG. 9 , taking N=3 as an example, the duration of the target paging cycle (that is, the new paging cycle in FIG. 9 ) is three times the duration of the current paging cycle. The current paging cycle is T, and the target paging cycle is 3T. As shown in FIG. 9 , optionally, the duration from 0 to time t is 3T, and within this duration there is only one paging moment carrying a paging message. If the paging cycle is T, within the duration, the terminal device needs to be woken up 3 times to monitor the paging message. If the paging cycle is 3T, within this duration, the terminal device only needs to be woken up once to monitor the paging message. The network device updates the paging cycle of the terminal device from T to 3T by sending paging cycle update information to the terminal device, thereby reducing the power consumption of the terminal device.

The duration of the target paging cycle indicated by the paging cycle update information may be greater than the duration of the current paging cycle, may be equal to the duration of the current paging cycle, or may be shorter than the duration of the current paging cycle.

The paging cycle update information includes an information bit, and when the paging cycle update information indicates the duration of the target paging cycle, the duration of the target paging cycle can be indicated according to the information bit.

Optionally, if the paging cycle update information indicates the target paging cycle through mode 1, the value of the target paging cycle may be indicated by an information bit in the paging cycle update information. For example, if the optional value set of the target paging cycle in mode 1 is {1,2,4,8,16,32,64,128,256,512,1024}, the unit of the optional value set is time slot, if the information bit is 0000 , it can indicate that the value of the target paging cycle is 1 time slot; if the information bit is 0001, it can indicate that the value of the target paging cycle is 2 time slots.

Optionally, if the paging cycle update information indicates the target paging cycle in mode 2, the information bits in the paging cycle update information may indicate that the target paging cycle is N times the current paging cycle. For example, if the information bit is 000, the duration of the corresponding target paging cycle can be 2^(-3)=0.125 times the duration of the current paging cycle; if the information bit is 001, the duration of the corresponding target paging cycle can be 2^(-2)=0.25 times the duration of the current paging cycle; if the information bit is 010, the corresponding target paging cycle duration can be 2^(-1)=0.5 times the duration of the current paging cycle ; If the information bit is 011, the duration of the corresponding target paging cycle can be 2^0=1 times of the duration of the current paging cycle; if the information bit is 100, the duration of the corresponding target paging cycle can be the current paging cycle 2^(1)=2 times the duration of the cycle; if the information bits are 101, the corresponding target paging cycle duration can be 2^(2)=4 times the duration of the current paging cycle, and so on.

FIG. 10 is a second schematic diagram of paging cycle update provided by the embodiment of the present application. As shown in FIG. 10 , the indication information is paging advance indication information as an example. The terminal device receives the paging advance indication information, and obtains the paging cycle update information according to the paging advance indication information. Optionally, the paging cycle update information indicates the duration of the target paging cycle (that is, the new paging cycle in FIG. 10 ) .

In FIG. 10 , the current paging cycle of the terminal device is 1280 ms, the first paging advance indication information includes paging cycle update information, and the paging cycle update information indicates that the duration of the target paging cycle is 5120 ms. The terminal device updates the paging cycle from 1280ms to 5120ms according to the paging cycle update information. In the next period, the terminal device receives the second paging advance indication information, the second paging advance indication information includes paging cycle update information, and the paging cycle update information indicates that the duration of the target paging cycle is 540ms. The terminal device updates the paging cycle from 5120ms to 540ms according to the paging cycle update information.

In the method for updating the paging cycle provided by the embodiment of the present application, firstly, when the terminal device is in an idle state or inactive state, it receives indication information modulated by on-off keying, and then updates the paging cycle of the terminal device according to the indication information. The paging cycle of the terminal device can be changed through the indication information, so the dynamic update of the paging cycle of the terminal device can be realized according to the demand of the service volume of the terminal device. For a terminal device that does not receive a paging message within a relatively long period of time, the solution of the embodiment of the present application can dynamically extend the duration of the paging cycle, thereby reducing the power consumption of the terminal device.

Optionally, the terminal device may also obtain the first parameter, and determine the effective time of the updated paging cycle according to the first parameter, and the effective time is the start time of the updated paging cycle.

Optionally, the first parameter may be a preset value, that is, the network device and the terminal device may pre-agree on the value of the first parameter. After the terminal device receives the indication information from the network device and updates its own paging cycle according to the indication information, optionally, it determines the start time for the new paging cycle to take effect according to the first parameter. The preset value may be, for example, 1280ms, 2560ms and so on.

Optionally, the first parameter may be a parameter configured by the network device. After the network device sends the paging cycle update information to the terminal device, it may also indicate the first parameter to the terminal device. After acquiring the first parameter, the terminal device determines the start time of the new paging cycle taking effect according to the first parameter. The network device may configure the first parameter according to the time interval between two adjacent POs. For example, in Figure 10, time t0 and time t1 correspond to a PO respectively, and the time interval between these two POs is 1280ms. At this time, the network device can configure the value of the first parameter to be 1280ms, and the new paging cycle is 1280ms effective after. Optionally, it can also be configured to take effect after 1280*2 according to the scenario.

Optionally, the start time for the new paging cycle indicated by the first parameter to take effect is the next paging moment.

FIG. 11 is a third schematic diagram of updating the paging cycle provided by the embodiment of the present application. As shown in FIG. 11 , the indication information is the paging advance indication information as an example. The terminal device receives the paging advance indication information, and obtains the paging cycle update information according to the paging advance indication information. Optionally, the paging cycle update information indicates the duration of the target paging cycle (that is, the new paging cycle in FIG. 11 ). .

The duration of the updated paging cycle in the example of FIG. 11 is the same as the duration of the updated paging cycle in the example of FIG. 10 , the difference lies in the starting time when the new paging cycle takes effect. In the example in Figure 10, the start time of the first new paging cycle (that is, the paging cycle with a length of 5120ms) is t0, and the second new paging cycle (that is, the paging cycle with a length of 540ms) ) starts to take effect at t3.

S121. The network device sends indication information modulated in an on-off keying manner, where the indication information is used to instruct a terminal device in an idle state or an inactive state to update a paging cycle.

Optionally, when the indication information belongs to the reference signal, the indication information is at least one of channel state information reference signal, primary synchronization signal, secondary synchronization signal, ZC sequence, and M sequence.

Optionally, when the network device sends the indication information to the terminal device, it may first modulate the indication information to obtain a modulated signal, and then send the modulated signal to the terminal device. After receiving the modulated signal, the terminal device demodulates the modulated signal to obtain the indication information.

Optionally, when modulating the indication information, the network device modulates the indication information based on an OOK modulation manner to obtain a modulated signal, and then sends the modulated signal to the terminal device.

Compared with QPSK, 16QAM, 64QAM and other modulation methods, the OOK modulation method is used to modulate the indication information, which can reduce the power of the terminal device when receiving the indication information, and save the power consumption of the receiver of the terminal device.

Optionally, the indication information may include a short message indication, and the short message indication is used to indicate that the paging occasion includes a short message and/or paging information. If the short message indicates that only short messages are included in the paging occasion, the corresponding paging occasion only needs to continue paging the short message in the PDCCH; and/or, if the short message indicates that only paging information is included in the paging occasion, or, The short message indicates that the paging occasion includes the paging information and the short message, and the terminal device needs to connect to the paging PDCCH and the paging PDSCH at the corresponding paging occasion.

Optionally, the indication information includes the identification of the terminal device and/or paging advance indication information, and the terminal device receives the identification of the terminal device and/or paging cycle update information from the network device, and then according to the identification of the terminal device and/or Paging cycle update information, updating the current paging cycle to the target paging cycle.

Optionally, the indication information may include a paging group identifier and/or paging advance indication information, and all terminal devices in the paging group may receive the paging group identifier and/or paging cycle update information from the network device, Then, according to the identity of the paging group and/or the paging cycle update information, the current paging cycle is updated to the target paging cycle, so as to update the paging cycle for the paging group.

S122. When the indication information satisfies the preset condition, the terminal device acquires the indication information modulated in the on-off keying manner.

Optionally, the indication information satisfies a preset condition, which means that the indication information includes at least one of two situations: paging cycle update information and indication information including a paging identifier. The paging identifier may include an identifier of a terminal device or an identifier of a paging group.

That is, when the indication information includes the paging cycle update information, or when the indication information includes the identification (UE_ID) of the terminal equipment, or when the indication information includes the paging cycle update information and the identification of the terminal equipment, the indication information satisfies the preset conditions.

That is, when the indication information includes paging cycle update information, or when the indication information includes the identifier of the paging group, or when the indication information includes the paging cycle update information and the identifier of the paging group, the indication information satisfies the preset conditions.

When the indication information satisfies the preset condition, the terminal device acquires the indication information, and updates the current paging cycle to the target paging cycle according to the indication information.

Optionally, when sending the indication information to the terminal device, the network device first modulates the indication information based on the OOK modulation mode to obtain a modulated signal, and then sends the modulated signal to the terminal device. Correspondingly, after receiving the modulated signal, the terminal device demodulates the modulated signal to obtain the indication information.

The OOK modulation method is a binary modulation, which uses a unipolar non-return-to-zero code sequence to control the on and off of the sinusoidal carrier. The modulation principle is to control one amplitude to be 0 and the other to be non-zero. Alternatively, a logical 1 is represented by sending a signal (ON), and a logical 0 is represented by not sending a signal (OFF). Therefore, compared with QPSK, 16QAM, 64QAM and other modulation methods, the OOK modulation method is used to modulate the indication information, which can reduce the power of the terminal device when receiving the indication information, and save the power consumption of the receiver of the terminal device.

Optionally, the indication information is paging advance indication information, and the terminal device obtains the paging advance indication information from the network device, and obtains paging cycle update information according to the paging advance indication information.

Optionally, when the indication information is the paging advance indication information, the paging advance indication information may be modulated in an OOK modulation manner to obtain a modulated signal, and then the modulated signal is sent to the terminal device. The terminal equipment receives the modulated signal, demodulates the modulated signal, and obtains the paging advance indication information. Similarly, modulating the paging advance indication information through OOK modulation can reduce the power of the terminal equipment when receiving the paging advance indication information, and save the power consumption of the receiver of the terminal equipment.

Optionally, the indication information can also be a reference signal, such as SSS, PSS, CSI-RS, ZC sequence, M sequence, etc.; optionally, the indication information can also be other occupied channel control resources except the paging advance indication information DCI.

S123. Update the paging cycle of the terminal device according to the indication information.

The indication is used to instruct the terminal equipment to update the paging cycle.

Optionally, the indication information instructs the terminal device to update the paging cycle to another specific paging cycle (ie, the target paging cycle). After receiving the indication information, the terminal device updates the current paging cycle of the terminal device according to the indication information. is the target paging cycle. The current paging cycle is the paging cycle before the terminal device is updated, and the target paging cycle is the paging cycle after the terminal device is updated. The duration of the updated target paging cycle may be greater than the duration of the current paging cycle of the terminal device, may also be shorter than the duration of the current paging cycle of the terminal device, and may also be equal to the duration of the current paging cycle of the terminal device.

For example, if the service type is enhanced Mobile Broadband (eMBB) or massive Machine Type of Communication (mMTC) service, the optional value set {1,2,3,4,5,8, 16, 32, 64, 128, 256}.

Optionally, N is 2 ^k , or, N is (1/2) ^k , and k is a natural number.

Optionally, the first parameter may be a parameter configured by the network device. After the network device sends the indication information to the terminal device, it may also indicate the first parameter to the terminal device. After acquiring the first parameter, the terminal device determines the start time of the new paging cycle taking effect according to the first parameter. The network device may configure the first parameter according to the time interval between two adjacent POs. For example, in Figure 10, time t0 and time t1 correspond to a PO respectively, and the time interval between these two POs is 1280ms. At this time, the network device can configure the value of the first parameter to be 1280ms, and the new paging cycle is 1280ms effective after. Optionally, it can also be configured to take effect after 1280*2 according to the scenario.
