Based on the above hardware structure of the terminal device and the communication network system, various embodiments of the present application are provided.
Fig. 3 is a schematic diagram of a paging cycle provided in an embodiment of the present application, and as shown in fig. 3, the paging cycle of a terminal device is 320 ms. In each Paging cycle, a Paging time is included, the terminal device is awakened at the Paging time of each Paging cycle, and monitors a PDCCH scrambled by a Paging Radio Network temporary Identity (P-RNTI) to acquire a Paging message.
In fig. 3, a paging advance indication message is further illustrated, and the paging advance indication message is used to indicate whether a paging message is transmitted at a current paging occasion (only one paging advance indication message is illustrated in fig. 3, in practice, a network device may send a paging advance indication message before each Paging Occasion (PO) starts to indicate whether a paging message is transmitted at a corresponding paging occasion). If yes, the terminal equipment is awakened, and monitoring of the paging message is carried out; and/or if not, not monitoring the paging message.
In some implementations, due to the different traffic of different terminal devices, a lightweight device, for example, may interact with a network device at longer intervals, which may be several seconds, minutes, or even hours. If the paging cycle is 320ms, the terminal device needs to be woken up and monitor the PDCCH every 320ms, so that the power consumption of the light-duty device is large.
Based on the above technical problem, embodiments of the present application provide a scheme for updating a paging cycle to reduce power consumption of a terminal device.
Fig. 4 is a signaling diagram of a paging cycle updating method according to an embodiment of the present application, and as shown in fig. 4, the method may include:
and S41, the network device sends the indication information modulated by the on-off keying mode, and the indication information is used for indicating the terminal device in an idle state or an inactive state to update the paging cycle.
The terminal device in the embodiment of the application may be a common device, and may also be a light-duty capability (RedCap) device, and the light-duty capability device may include, for example, a refrigerator, a television, an air conditioner, and other household appliances, and may include, for example, a smart watch, a wearable device such as a sports bracelet, and the like. The bandwidth, data rate and the like of the light capacity equipment are different from those of ordinary equipment.
Optionally, the terminal device may be in an RRC idle state; optionally, the terminal device may be in an RRC inactive state, which may also be referred to as an inactive state.
And the terminal equipment determines the paging occasion according to the UE _ ID and the paging cycle of the terminal equipment. After the paging occasion is determined, the terminal equipment is awakened at the timing of the paging occasion to monitor whether the current paging occasion has a paging message.
For example, if the current paging cycle is 1280ms, the terminal device may be awakened every 1280ms to monitor whether there is a paging message.
Optionally, when the network device sends the indication information to the terminal device, the indication information is modulated by an OOK modulation method to obtain the indication information modulated by the OOK modulation method. Generally, the indication information is modulated by Modulation schemes such as Quadrature Phase Shift Keying (QPSK), 16 Quadrature Amplitude Modulation (16 QAM), and 64QAM, and when demodulating the indication information, a high-power receiver is required, which results in large power consumption of the receiver of the terminal device. Based On this, the embodiment of the present application provides a modulation method based On-Off Keying (OOK for short) to transmit indication information.
Fig. 5 is a schematic diagram of a modulation process of indication information provided in an embodiment of the present application, as shown in fig. 5, including:
s51, the network device encodes and interleaves the binary bits associated with the indication information.
S52, the network device performs OOK modulation on the coded and interleaved binary bits.
S53, the network device performs Inverse Fast Fourier Transform (IFFT) and Cyclic Prefix (CP) insertion processing on the OOK-modulated indication information, to obtain a modulated signal.
And S54, the network equipment sends the modulated signal to the terminal equipment through the antenna.
The OOK modulation is a binary modulation, which uses a unipolar non-return-to-zero code sequence to control the on and off of a sinusoidal carrier, and the modulation principle is to control one amplitude to be 0 and the other amplitude to be non-0. Alternatively, a logic 1 is represented by a send signal (ON) and a logic 0 is represented by a do not occur signal (OFF).
Optionally, when the network device sends the indication information to the terminal device, the network device firstly 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 modulation signal, the terminal device demodulates the modulation signal, and thus the indication information can be obtained. Compared with modulation modes such as QPSK, 16QAM and 64QAM, the OOK modulation mode is used for modulating the indication information, so that the power of the terminal equipment when receiving the indication information can be reduced, and the power consumption of a receiver of the terminal equipment can be saved.
And S42, the terminal equipment receives the indication information modulated by the on-off keying mode.
After the network device sends the indication information, the terminal device receives the indication information, and the indication information is used for indicating the terminal device to update the paging cycle.
Optionally, the indication information may instruct the terminal device to update the paging cycle to a paging cycle with a longer duration, or instruct the terminal device to update the paging cycle to a paging cycle with a shorter duration.
Alternatively, the indication information may instruct the terminal device to update the paging cycle to another specific paging cycle, i.e. 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 of 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, the terminal device updates the paging cycle to the target paging cycle according to the indication of the indication information, and so on.
And S43, the terminal equipment updates the paging cycle of the terminal equipment according to the indication information.
After the terminal device receives the indication information, the paging cycle of the terminal device may be updated according to the indication information.
Optionally, if the indication information indicates that the terminal device updates the paging cycle to another specific paging cycle, the network device indicates the updated paging cycle through the indication information. And the terminal equipment switches to the paging cycle indicated by the network equipment according to the indication information. The duration of the updated paging cycle may be greater than the current paging cycle of the terminal device, may also be less 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 traffic load. Alternatively, the current traffic load may be, for example, the frequency of data volume transmission by the terminal device, and may be, for example, the number of terminal devices accessing the network.
When the current traffic load includes the frequency of the data volume transmitted by the terminal device, a frequency threshold range may be preset, and whether the paging cycle needs to be updated is determined according to the frequency threshold range and the frequency of the data volume transmitted in a certain time period. For example, when the frequency of the transmission data amount is greater than or equal to a first threshold value within a certain time period, the network device determines that the paging cycle of the terminal device needs to be updated; for another example, when the frequency of the amount of transmission data is less than or equal to the second threshold value within a certain period of time, the network device determines that the paging cycle of the terminal device needs to be updated, and so on.
This is illustrated by a specific example. The selectable 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 in the interval range of 1280ms to 2560 ms. Optionally, the value of the first threshold is 1280ms, the current paging cycle of the terminal device is 320ms, and 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 may be updated to 1280 ms. 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 may be updated to 1280 ms.
When the current service load includes the number of terminal devices accessing the network, the network device may 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 a third threshold, the network device determines that the paging cycle of the terminal device needs to be updated; for another example, when the number of terminal devices currently accessing the network is less than or equal to the fourth threshold, the network device determines that the paging cycle of the terminal device needs to be updated, and so on.
This is illustrated by a specific example. If the number of terminal devices that are currently paged at the maximum time allowed by the network is 64, the third threshold may be 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, and may allocate more than 64 terminal devices in a plurality of paging cycles by shortening the paging cycle. For example, when the number of terminal devices is 70 and the paging cycle is 5120ms, the paging cycle may be updated to 2560ms, such that some terminal devices are placed in the previous paging cycle of 2560ms duration and another part of terminal devices are placed in the next paging cycle of 2560ms duration. A fourth threshold value may be set when the number of terminal devices is small. For example, the fourth threshold is set to 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 device 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 5120 ms.
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 the indication information to the terminal device.
Optionally, the indication information belongs to a reference signal or downlink control information.
Optionally, when the indication information belongs to a reference Signal, the indication information is any one of a channel state information reference Signal (CSI-RS), a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (PSS), a ZC sequence (Zadoff-Chu sequence), and an M sequence.
Optionally, when the indication information belongs to DCI, the indication information is paging advance indication information, or DCI occupying channel control resources other than the paging advance indication information.
When the indication information belongs to the reference signal or the DCI, the terminal device is facilitated to obtain the paging cycle information through corresponding detection at a specified time, and compared with a mode of updating the paging cycle through RRC signaling or a system message, the mode of updating the paging cycle through the reference signal or the DCI is more flexible. Furthermore, the time-frequency resource occupied by the mode of updating the paging cycle through the reference signal or the DCI is less, so that the terminal device can obtain longer sleep or shorter paging response through less system cost.
Optionally, the indication information may include a short message indication, where 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 the paging occasion only comprises the short message, the corresponding paging occasion only needs to continue the short message in the paging PDCCH; and/or if the paging occasion indicated by the short message only includes paging information, or the paging occasion indicated by the short message includes paging information and a short message, the terminal equipment needs to continue paging the PDCCH and paging the PDSCH in the corresponding paging occasion.
Optionally, the indication information includes an identifier of the terminal device and/or paging advance indication information, the terminal device receives the identifier of the terminal device and/or paging cycle update information from the network device, and then updates the current paging cycle to the target paging cycle according to the identifier of the terminal device and/or paging cycle update information.
Since paging is usually performed for a group of terminal devices with the same paging occasion, if the indication information does not include the identifier of the terminal device, all the terminal devices in the group of terminal devices with the same paging occasion need to receive the indication information, but only a specific terminal device may need to update the paging cycle, which may cause unnecessary monitoring.
In the embodiment of the application, the identifier of the terminal device may be set in the indication information, where the identifier is used to distinguish the terminal device from other terminal devices, and the identifiers of different terminal devices are different. Therefore, when the indication information includes the identifier of the terminal device, only the terminal device corresponding to the identifier needs to receive the indication information and update the paging cycle according to the indication information, and other terminal devices do not need to receive the indication information and update the paging cycle according to the indication information.
In the example of fig. 3, the paging advance indication information is introduced, which is used to indicate whether the terminal device has a paging message at a paging occasion. After the terminal equipment receives the paging advance indication information, if the paging advance indication information indicates that the paging occasion has the paging message, the terminal equipment receives the paging message at the paging occasion, and if the paging advance indication information indicates that the paging occasion has no paging message, the terminal equipment does not need to receive the paging message at the current paging occasion, so that the power consumption of the terminal equipment is saved.
Optionally, the paging advance indication information may also be implemented as an indication information in addition to indicating whether a paging message exists in a paging cycle, that is, the indication information may be the paging advance indication information.
Fig. 6 is a schematic diagram of paging cycle update provided in an embodiment of the present application, and as shown in fig. 6, illustrates a manner of instructing, by indication information, a terminal device to update a paging cycle. In the example of fig. 6, the indication information includes an identifier of the terminal device and/or paging cycle update information, the network device sends OOK-modulated indication information to the terminal device, the terminal device receives the indication information, and updates the current paging cycle to the target paging cycle according to the indication information. In fig. 6, the indication information is introduced as paging advance indication information, and actually, the indication information may further include other implementation manners, for example, reference signal forms such as SSS and PSS, or other DCI forms.
Generally, the paging advance indication information is for paging groups, and a plurality of UEs may be included in one paging group, as shown in the left side of fig. 6, illustrating 3 UEs included in one paging group, which are UE1, UE2, and UE3, respectively. When the network device sends the paging advance indication information, the UE1, the UE2, and the UE3 all receive the paging advance indication information, and as long as at least one UE of the three UEs has a paging message at the next paging occasion, the paging advance indication information indicates that the next paging occasion needs to receive the paging message, and the three UEs are all awakened at the next paging occasion and monitor the paging message, thereby determining whether the paging message is sent to the UE.
However, in a paging group, some UEs may need to receive the paging message and some UEs may not need to receive the paging message in the next paging occasion. For the UE that does not have the paging message to receive, the UE still needs to be woken up to listen for the paging message. For example, in fig. 6, UE1 is a lightweight device that may need to interact with network devices several minutes or even hours apart, while UE2 and UE3 are normal devices with a paging cycle of 320 ms. When there is UE in the 3 UEs that needs to receive the paging message, all three UEs will be awakened through the paging advance indication information, and monitor the paging message. For the light-weight UE1, it needs to listen for the paging message every 320ms, and the network side does not page the UE1, which causes a large power consumption of the UE 1.
In order to solve the above technical problem, an identifier (UE _ ID) of a terminal device may be set in the paging advance indication information, as shown in the right side of fig. 6, where the identifier of the terminal device in the paging advance indication information is used to instruct the terminal device to determine whether the paging advance indication information is paging advance indication information sent to itself. For example, if the paging advance indication information includes the identifier of the UE1, the UE1 knows that the paging advance indication information is for the UE1, and the UE1 receives the paging advance indication information and performs a subsequent response according to the indication of the paging advance indication information. If the identity of the UE1 is not included in the paging advance indication information, the UE1 knows that the paging advance indication information is not information for the UE1, and does not need to perform any response.
When the indication information is PEI, the PEI is carried in a variety of different ways, for example, the PEI comprises a DCI-based PEI (DCI-based PEI) and a sequence-based PEI (sequence-based PEI) through a sequence mapping, and optionally, the sequence-based PEI comprises a PEI (SSS-based PEI) carried through an SSS reference signal mapping and a PEI carried through a TRS reference signal mapping (TRS/CSI-RS-based PEI).
The DCI-based PEI and the sequence-based PEI are generally modulated by a Modulation scheme such as Quadrature Phase Shift Keying (QPSK), 16 Quadrature Amplitude Modulation (16 QAM), 64QAM, and the like, and when demodulating the DCI-based PEI and the sequence-based PEI, a high-power receiver is required, which results in large power consumption of the receiver of the terminal device. Based On this, the embodiment of the present application provides a modulation method based On-Off Keying (OOK for short) to transmit indication information.
Optionally, when the network device sends the indication information to the terminal device, the network device firstly 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 modulation signal, the terminal device demodulates the modulation signal, and thus the indication information can be obtained.
In the above embodiment, the manner of receiving the indication information is described, and the following description will be made on the way that the terminal device updates the paging cycle according to the indication information.
And after the terminal equipment receives the indication information, updating the current paging cycle of the terminal equipment to the target paging cycle according to the indication information. The current paging cycle is the paging cycle before the terminal equipment is updated, and the target paging cycle is the paging cycle after the terminal equipment 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 paging cycle update information indicates that the target paging cycle is N times of the current paging cycle, where N is a positive number.
And 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 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, and so on.
Alternatively, when N is a positive number less than or equal to 1, N may be (1/2)kK is a natural number, and the value of k may be, for example, 0,1,2, 3. Taking the current paging cycle as 2560ms as an example, when N takes 1,1/2,1/4,1/8, respectively, the target paging cycles are 2560ms, 1280ms, 640ms, 320ms, respectively. And 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.
And when N is a positive number larger than 1, the duration of the updated target paging cycle is larger than the current paging cycle before updating. For example, when N is 2, the duration of the target paging cycle is 2 times 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, and so on.
Alternatively, when N is a positive number greater than 1, N may be 2kK is a natural number, and the value of k may be, for example, 1,2, 3. 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. And 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 value of N, the value of k, and the value of the current paging cycle are all examples, and do not limit the actual values.
Fig. 7 is a first schematic diagram of updating a paging cycle according to an embodiment of the present application, and as shown in fig. 7, the indication information is taken as paging advance indication information as an example. The terminal equipment receives the paging advance indication information, acquires paging cycle update information according to the paging advance indication information, and optionally, the paging cycle update information indicates that the target paging cycle is N times of the current paging cycle.
In the example of fig. 7, taking N =3 as an example, the duration of the target paging cycle (i.e., the new paging cycle in fig. 7) is 3 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. 7, optionally, the time duration from 0 to T is 3T, and there is only one paging time carrying the paging message in the time duration. If the paging cycle is T, the terminal device needs to be awakened 3 times within the duration, and the paging message is monitored. If the paging cycle is 3T, the terminal device only needs to be awakened for 1 time within the duration, and then the paging message is monitored. The network equipment updates the paging cycle of the terminal equipment from T to 3T by sending paging cycle updating information to the terminal equipment, thereby reducing the power consumption of the terminal equipment.
Optionally, the paging cycle update information indicates a duration of the target paging cycle.
The duration of the target paging cycle indicated by the paging cycle update information may be longer 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 may be indicated according to the information bit. For example, when the information bit is 000, the duration of the corresponding target paging cycle is 320 ms; when the information bit is 001, the duration of the corresponding target paging cycle is 640 ms; when the information bit is 010, the time length of the corresponding target paging cycle is 1280 ms; when the information bit is 011, the duration of the corresponding target paging cycle is 2560 ms; when the information bit is 100, the duration of the corresponding target paging cycle is 5120 ms; when the information bit is 101, the duration of the corresponding target paging cycle is 10240ms, and so on.
Fig. 8 is a schematic diagram of a second method for updating a paging cycle according to an embodiment of the present application, and as shown in fig. 8, the indication information is taken as paging advance indication information as an example. The terminal device receives the paging advance indication information, and acquires the paging cycle update information according to the paging advance indication information, optionally, the paging cycle update information indicates a duration of a target paging cycle (i.e., a new paging cycle in fig. 8).
In fig. 8, the current paging cycle of the terminal device is 1280ms, the first paging advance indication information includes paging cycle update information, and the duration of the paging cycle update information indicating the target paging cycle is 5120 ms. And the terminal equipment updates the paging cycle from 1280ms to 5120ms according to the paging cycle updating information. In the next cycle, the terminal device receives second paging advance indication information, where 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 540 ms. The terminal equipment updates the paging cycle from 5120ms to 540ms according to the paging cycle updating information.
The paging cycle updating method provided by the embodiment of the application receives the indication information modulated in the on-off keying mode when the terminal equipment is in an idle state or an inactive state, and then updates the paging cycle of the terminal equipment according to the indication information. The paging cycle of the terminal equipment can be changed through the indication information, so that the dynamic update of the paging cycle of the terminal equipment can be realized according to the requirement of the traffic of the terminal equipment. For a terminal device which does not receive a paging message in a longer time period, the scheme of the embodiment of the application can dynamically prolong the time of the paging cycle, thereby reducing the power consumption of the terminal device.
Optionally, the terminal device may further obtain the first parameter, and determine an effective time of the updated paging cycle according to the first parameter, where the effective time is a starting 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 agree in advance on a value of the first parameter. After receiving the indication information from the network device and updating the paging cycle of the terminal device according to the indication information, the terminal device optionally determines the starting time of the new paging cycle according to the first parameter. The preset value may be 1280ms, 2560ms, etc., for example.
Alternatively, the first parameter may be a parameter configured by the network device. The network device may further indicate the first parameter to the terminal device after sending the paging cycle update information to the terminal device. After the terminal equipment acquires the first parameter, the starting time of the new paging cycle is determined according to the first parameter. The network device may configure the first parameter according to a time interval between two adjacent POs. For example, in fig. 8, a time t0 and a time t1 correspond to one PO respectively, and a time interval between the two POs is 1280ms, at this time, the network device may configure a first parameter value 1280ms, and then a new paging cycle starts to take effect after 1280 ms. Optionally, the system can also start to take effect after 1280 × 2 according to the scene configuration.
Optionally, the starting time of the new paging cycle, which is indicated by the first parameter, being effective is the next paging time.
Fig. 9 is a third schematic diagram of updating a paging cycle according to an embodiment of the present application, and as shown in fig. 9, the indication information is taken as paging advance indication information as an example. The terminal device receives the paging advance indication information, and acquires 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 (i.e., the new paging cycle in fig. 9).
The updated duration of the paging cycle in the example of fig. 9 is the same as the updated duration of the paging cycle in the example of fig. 8, except for the start time at which the new paging cycle takes effect. In the example of fig. 8, the first new paging cycle (i.e., a paging cycle of duration 5120 ms) takes effect at a start time t0, and the second new paging cycle (i.e., a paging cycle of duration 540 ms) takes effect at a start time t 3.
In the example of fig. 9, the first new paging cycle (i.e., a paging cycle of duration 5120 ms) takes effect at a start time of (t 0+1280 ms), optionally 1280ms is the first parameter. The starting time for the second new paging cycle (i.e. the paging cycle with duration of 540 ms) to take effect is (t 3+540 ms), i.e. t4 in fig. 9, optionally 540ms is the first parameter.
It should be noted that the value of the first parameter in fig. 9 is only an example, and does not constitute a limitation on the value of the first parameter.
Fig. 10 is a signaling diagram of a paging cycle updating method according to an embodiment of the present application, as shown in fig. 10, including:
s101, the network equipment sends the indication information modulated by the on-off keying mode, and the indication information is used for indicating the terminal equipment in an idle state or an inactive state to update the paging cycle.
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 traffic load. Alternatively, the current traffic load may be, for example, the frequency of data volume transmission of the terminal device, and may be, for example, the number of terminal devices accessing the network.
When the current traffic load includes the frequency of the data volume transmitted by the terminal device, a frequency threshold range may be preset, and whether the paging cycle needs to be updated is determined according to the frequency threshold range and the frequency of the data volume transmitted in a certain time period. For example, when the frequency of the amount of transmission data is greater than or equal to a first threshold value within a certain time period, the network device determines that the paging cycle of the terminal device needs to be updated; for another example, when the frequency of the amount of transmission data is less than or equal to the second threshold value within a certain period of time, the network device determines that the paging cycle of the terminal device needs to be updated, and so on.
This is illustrated by a specific example. The selectable 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 in the interval range of 1280ms to 2560 ms. Optionally, the value of the first threshold is 1280ms, the current paging cycle of the terminal device is 320ms, and 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 may be updated to 1280 ms. 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 may be updated to 1280 ms.
When the current service load includes the number of terminal devices accessing the network, the network device may 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 a third threshold, the network device determines that the paging cycle of the terminal device needs to be updated; for another example, when the number of terminal devices currently accessing the network is less than or equal to the fourth threshold, the network device determines that the paging cycle of the terminal device needs to be updated, and so on.
This is illustrated by a specific example. If the number of terminal devices that are currently paged at the maximum time allowed by the network is 64, the third threshold may be 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, and may allocate more than 64 terminal devices in a plurality of paging cycles by shortening the paging cycle. For example, when the number of terminal devices is 70 and the paging cycle is 5120ms, the paging cycle may be updated to 2560ms, such that some terminal devices are placed in the previous paging cycle of 2560ms duration and another part of terminal devices are placed in the next paging cycle of 2560ms duration. A fourth threshold value may be set when the number of terminal devices is small. For example, the fourth threshold is set to 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 device 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 5120 ms.
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 the indication information to the terminal device.
Optionally, the indication information belongs to a reference signal or downlink control information.
Optionally, when the indication information belongs to the reference signal, the indication information is any one of a channel state information reference signal, a primary synchronization signal, a secondary synchronization signal, a ZC sequence, and an M sequence.
Optionally, when the indication information belongs to the DCI, the indication information is paging advance indication information, or the DCI occupying the channel control resource is other than the paging advance indication information.
When the indication information belongs to the reference signal or the DCI, the terminal device is facilitated to obtain the paging cycle information through corresponding detection at a specified time, and compared with a mode of updating the paging cycle through RRC signaling or a system message, the mode of updating the paging cycle through the reference signal or the DCI is more flexible. Furthermore, the time-frequency resource occupied by the mode of updating the paging cycle through the reference signal or the DCI is less, so that the terminal device can obtain longer sleep or shorter paging response through less system cost.
Optionally, when the network device sends the indication information to the terminal device, the indication information may be modulated to obtain a modulated signal, and then the modulated signal is sent to the terminal device. And after receiving the modulation signal, the terminal equipment demodulates the modulation signal to obtain the indication information.
Optionally, when the network device modulates the indication information, the network device modulates the indication information based on an OOK modulation scheme to obtain a modulated signal, and then sends the modulated signal to the terminal device.
Compared with modulation modes such as QPSK, 16QAM and 64QAM, the OOK modulation mode is used for modulating the indication information, so that the power of the terminal equipment when receiving the indication information can be reduced, and the power consumption of a receiver of the terminal equipment can be saved.
Optionally, the indication information may include a short message indication, where 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 the paging occasion only comprises the short message, the corresponding paging occasion only needs to continue the short message in the paging PDCCH; and/or if the paging occasion indicated by the short message only comprises paging information, or the paging occasion indicated by the short message comprises the paging information and the short message, the terminal equipment at the corresponding paging occasion needs to continue paging PDCCH and paging PDSCH.
Optionally, the indication information includes an identifier of the terminal device and/or paging advance indication information, the terminal device receives the identifier of the terminal device and/or paging cycle update information from the network device, and then updates the current paging cycle to the target paging cycle according to the identifier of the terminal device and/or the paging cycle update information.
Since paging is usually performed for a group of terminal devices with the same paging occasion, if the indication information does not include the identifier of the terminal device, all the terminal devices in the group of terminal devices with the same paging occasion need to receive the indication information, but only a specific terminal device may need to update the paging cycle, which may cause unnecessary monitoring.
In the embodiment of the application, the identifier of the terminal device may be set in the indication information, where the identifier is used to distinguish the terminal device from other terminal devices, and the identifiers of different terminal devices are different. Therefore, when the indication information includes the identifier of the terminal device, only the terminal device corresponding to the identifier needs to receive the indication information and update the paging cycle according to the indication information, and other terminal devices do not need to receive the indication information and update the paging cycle according to the indication information.
And S102, when the indication information meets the preset condition, the terminal equipment acquires the indication information modulated in the on-off keying mode.
Optionally, the indication information satisfies a preset condition, and indicates that the indication information includes at least one of paging cycle update information and that the indication information includes an identifier of the terminal device.
That is, when the indication information includes paging cycle update information, or when the indication information includes an identity (UE _ ID) of the terminal device, or when the indication information includes paging cycle update information and an identity of the terminal device, the indication information satisfies the preset condition.
And when the indication information meets the preset condition, the terminal equipment acquires the indication information and updates the current paging cycle to the target paging cycle according to the indication information.
Optionally, when the network device sends the indication information to the terminal device, the network device firstly modulates the indication information based on the OOK modulation scheme to obtain a modulated signal, and then sends the modulated signal to the terminal device. Correspondingly, after receiving the modulation signal, the terminal device demodulates the modulation signal, and thus the indication information can be obtained.
The OOK modulation is a binary modulation, which uses a unipolar non-return-to-zero code sequence to control the on and off of a sinusoidal carrier, and the modulation principle is to control one amplitude to be 0 and the other amplitude to be non-0. Alternatively, a logic 1 is represented by a send signal (ON) and a logic 0 is represented by a do not occur signal (OFF). Therefore, the indication information is modulated by the OOK modulation scheme, as compared with the QPSK, 16QAM, 64QAM, or other modulation schemes, so that the power of the terminal device when receiving the indication information can be reduced, and the power consumption of the receiver of the terminal device can be reduced.
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 paging advance indication information, the paging advance indication information may be modulated in an OOK modulation manner to obtain a modulation signal, and then the modulation signal is sent to the terminal device. And the terminal equipment receives the modulation signal, demodulates the modulation signal and obtains the paging advance indication information. Similarly, the paging advance indication information is modulated by an OOK modulation mode, which can reduce the power of the terminal device when receiving the paging advance indication information and save the power consumption of the receiver of the terminal device.
Optionally, the indication information may also be a reference signal, such as SSS, PSS, CSI-RS, ZC sequence, M sequence, etc.; alternatively, the indication information may be DCI occupying a channel control resource other than the paging advance indication information.
And S103, updating the paging cycle of the terminal equipment according to the indication information.
The indication 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 paging cycle with a longer duration, or instruct the terminal device to update the paging cycle to a paging cycle with a shorter duration.
Optionally, the indication information indicates the terminal device to update the paging cycle to another specific paging cycle (i.e., a target paging cycle), and 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 equipment is updated, and the target paging cycle is the paging cycle after the terminal equipment is updated. The updated duration of the target paging cycle may be longer 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.
Optionally, the paging cycle update information in the indication information indicates that the target paging cycle is N times of the current paging cycle, where N is a positive number.
Alternatively, N is 2kOr, N is (1/2)kAnd k is a natural number.
And 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 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, and so on.
Alternatively, when N is a positive number less than or equal to 1, N may be (1/2)kK is a natural number, and the value of k can be 0,1,2,3, correspondingly, the value of N can be 1,1/2,1/4, 1/8. Taking the current paging cycle as 2560ms as an example, when N takes 1,1/2,1/4,1/8, respectively, the target paging cycles are 2560ms, 1280ms, 640ms, 320ms, respectively. And 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.
And when N is a positive number larger than 1, the duration of the updated target paging cycle is larger than the current paging cycle before updating. For example, when N is 2, the duration of the target paging cycle is 2 times 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, and so on.
Alternatively, when N is a positive number greater than 1, N may be 2kK is a natural number, and the value of k may be, for example, 1,2, 3. 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. And 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 value of N, the value of k, and the value of the current paging cycle are all examples, and do not limit the actual values.
Optionally, the paging cycle update information indicates a duration of the target paging cycle.
The duration of the target paging cycle indicated by the paging cycle update information may be longer 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 may be indicated according to the information bit. For example, when the information bit is 000, the duration of the corresponding target paging cycle is 320 ms; when the information bit is 001, the duration of the corresponding target paging cycle is 640 ms; when the information bit is 010, the time length of the corresponding target paging cycle is 1280 ms; when the information bit is 011, the duration of the corresponding target paging cycle is 2560 ms; when the information bit is 100, the duration of the corresponding target paging cycle is 5120 ms; when the information bit is 101, the duration of the corresponding target paging cycle is 10240ms, and so on.
Optionally, the terminal device may further obtain the first parameter, and determine an effective time of the updated paging cycle according to the first parameter, where the effective time is a starting 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 agree in advance on a value of the first parameter. After receiving the indication information from the network device and updating the paging cycle of the terminal device according to the indication information, the terminal device optionally determines the starting time of the new paging cycle according to the first parameter. The preset value may be 1280ms, 2560ms, etc., for example.
Alternatively, the first parameter may be a parameter configured by the network device. After the network device sends the indication information to the terminal device, the network device may also indicate the first parameter to the terminal device. After the terminal equipment acquires the first parameter, the starting time of the new paging cycle is determined according to the first parameter. The network device may configure the first parameter according to a time interval between two adjacent POs. For example, in fig. 8, a time t0 and a time t1 correspond to one PO respectively, and a time interval between the two POs is 1280ms, at this time, the network device may configure a first parameter value 1280ms, and then a new paging cycle starts to take effect after 1280 ms. Optionally, the system can also start to take effect after 1280 × 2 according to the scene configuration.
Optionally, the starting time of the new paging cycle, which is indicated by the first parameter, being effective is the next paging time.
The paging cycle updating method provided by the embodiment of the application receives the indication information modulated in the on-off keying mode when the terminal equipment is in an idle state or an inactive state, and then updates the paging cycle of the terminal equipment according to the indication information. The paging cycle of the terminal equipment can be changed through the indication information, so that the dynamic update of the paging cycle of the terminal equipment can be realized according to the requirement of the traffic of the terminal equipment. For a terminal device which does not receive a paging message in a longer time period, the scheme of the embodiment of the application can dynamically prolong the time of the paging cycle, thereby reducing the power consumption of the terminal device.
