Communication method and device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on April 3, 2024, with application number 202410405517.2 and application name “Communication Method and Device,” the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technologies, and in particular to communication methods and devices. Background Art

[0003] In a communication system, a terminal device may include a low-power receiver and a main receiver (the power consumption of the main receiver is greater than that of the low-power receiver). The terminal device may receive a wake-up signal from a network device through the low-power receiver, and determine whether to activate the main receiver of the terminal device based on the wake-up signal. Furthermore, the terminal device may transmit data with the network device through the main receiver.

[0004] However, when the low-power receiver of the terminal device cannot interpret the wake-up signal but attempts to receive the wake-up signal, the power consumption of the terminal device will increase.

[0005] Therefore, how to reduce the power consumption of terminal equipment has become an urgent problem to be solved. Summary of the Invention

[0006] The embodiments of the present application provide a communication method and apparatus that can reduce the power consumption of terminal equipment.

[0007] In a first aspect, a communication method is provided, which can be executed by a terminal device. Unless otherwise specified, the "terminal device" in this application can refer to the terminal device itself, or a component in the terminal device (for example, a processor, a chip, or a chip system, etc.), or a logic module or software that can realize all or part of the functions of the terminal device. The method includes: the terminal device receives a first indication information; and determines whether to activate the second receiver based on the first indication information. The first indication information is used to indicate one or more of the following: the modulation mode of the first signal, the number of sequences superimposed on the first signal, whether the network device supports activating the second receiver of the terminal device, and whether the network device allows activation of the second receiver of the terminal device; the first signal is used to wake up the first receiver of the terminal device; the power consumption of the first receiver is greater than the power consumption of the second receiver.

[0008] Herein, used to indicate can be understood as used to determine, or can be understood as including.

[0009] Based on this scheme, the first indication information can indicate the modulation mode of the first signal, and the terminal device can determine whether to activate the second receiver by determining whether the demodulation mode of the second receiver is the demodulation mode corresponding to the modulation mode of the first signal; or, the first indication information can indicate the number of sequences superimposed on the first signal, and the terminal device can determine the modulation mode of the first signal based on the number of sequences superimposed on the first signal, and can determine whether to activate the second receiver by determining whether the demodulation mode of the second receiver is the demodulation mode corresponding to the modulation mode of the first signal; or, the first indication information can directly indicate the terminal device whether to activate the second receiver.

[0010] The terminal device can determine, based on the first indication information, whether the second receiver of the terminal device can successfully parse the first signal, and then determine whether to activate the second receiver. In this manner, when the terminal device activates the second receiver, it can minimize the possibility of the terminal device attempting to receive the first signal despite being unable to parse it, thereby effectively reducing the power consumption of the terminal device. Alternatively, in this manner, when the terminal device determines that it cannot parse the first signal, it can directly put the second receiver into a dormant state, thereby effectively reducing the power consumption of the terminal device.

[0011] One possible implementation is that when the demodulation method supported by the second receiver is the demodulation method corresponding to the modulation method of the first signal, the terminal device activates the second receiver; or, when the demodulation method supported by the second receiver is not the demodulation method corresponding to the modulation method of the first signal, the terminal device does not activate the second receiver.

[0012] Based on this possible implementation, a feasible solution is provided for the terminal device to determine whether to activate the second receiver, that is, the terminal device can directly determine whether the demodulation mode supported by the second receiver is the demodulation mode corresponding to the modulation mode of the first signal based on the modulation mode of the first signal indicated by the first indication information; or, the terminal device can determine the modulation mode of the first signal based on the number of sequences superimposed on the first signal indicated by the first indication information, and then determine whether the demodulation mode supported by the second receiver is the demodulation mode corresponding to the modulation mode of the first signal; or, the terminal device can instruct the network device whether to activate the second receiver based on the first indication information, and determine that the modulation mode of the first signal does not correspond to the demodulation mode supported by the second receiver.

[0013] Among them, when the terminal device determines that the demodulation method supported by the second receiver is the demodulation method corresponding to the modulation method of the first signal, the second receiver can be activated. At this time, the situation where the terminal device cannot parse the first signal but tries to receive the first signal can be avoided as much as possible, and the power consumption of the terminal device can be reduced.

[0014] In one possible implementation, the first indication information is used to indicate one or more of the following: the network device allows activation of the second receiver of the terminal device, the network device does not allow activation of the second receiver of the terminal device, the network device supports activation of the second receiver of the terminal device, the network device does not support activation of the second receiver of the terminal device, the type of terminal device that the network device allows activation of the second receiver, the type of terminal device that the network device does not allow activation of the second receiver, the type of terminal device that the network device supports activation of the second receiver, the type of terminal device that the network device does not support activation of the second receiver, the time period during which the network device allows activation of the second receiver of the terminal device, the time period during which the network device does not allow activation of the second receiver of the terminal device, the time period during which the network device supports activation of the second receiver of the terminal device, the time period during which the network device does not support activation of the second receiver of the terminal device, the working frequency supported by the network device, the maximum number of working frequencies supported by the terminal device supported by the network device, resources supported by the network device for sending the first signal, the terminal device that the network device allows supporting the working frequency to receive the first signal, the working frequency supported by the network device is less than the first preset frequency, and the working frequency supported by the network device is greater than the second preset frequency.

[0015] Based on this possible implementation, several feasible solutions are provided for implementing the first indication information.

[0016] Among them, the first indication information can directly instruct the terminal device whether to activate the second receiver, which can improve the working efficiency of the terminal device and reduce the workload of the terminal device.

[0017] Among them, the first indication information can indicate the type of terminal device to enable the terminal device to determine whether to activate the second receiver. The network device can send a first message to instruct multiple terminal devices to determine whether to activate the second receiver, which can effectively reduce the transmission overhead. At the same time, it can effectively reduce the load of the network device and improve the working efficiency of the network device.

[0018] Among them, the first indication information can indicate a time period so that the terminal device can determine the time period for activating the second receiver and the time period for not activating the second receiver. This can ensure that the terminal device successfully parses the received first signal during the time period when the second receiver is activated, and can also ensure that the network device does not send the first signal to the terminal device during the time period when the second receiver is not activated, thereby improving the efficiency of information interaction between the terminal device and the network device. In addition, the network device can dynamically indicate the time period for activating the second receiver of the terminal device according to the actual communication scenario or communication situation. By configuring different time periods, different types of terminal devices can activate the second receiver in different time periods, which can meet the load balancing requirements of the network device and improve the flexibility of determining the time period.

[0019] The first indication information may indicate the capability of the network device to serve the terminal device (such as the frequency supported by the network device) so that the terminal device can determine whether to activate the second receiver.

[0020] In one possible implementation, the terminal device receives the first indication information from the network device; or, the terminal device receives the first indication information from the core network device.

[0021] Based on this possible implementation, the terminal device can receive the first indication information from the network device or the core network device, which can improve the diversity of the transmission of the first indication information.

[0022] In one possible implementation, the terminal device receives the first signal through the second receiver.

[0023] In one possible implementation, the terminal device determines whether to activate a first receiver of the terminal device according to the first signal.

[0024] Based on the above two possible implementations, the terminal device can determine to activate the first receiver of the terminal device according to the received first signal, thereby providing a feasible solution for the terminal device to activate the first receiver.

[0025] In one possible implementation, the terminal device receives second indication information, and receives the first signal according to the second indication information, wherein the second indication information is used to indicate a resource for the terminal device to receive the first signal.

[0026] In one possible implementation, the second indication information includes one or more of the following: time domain resource information, frequency domain resource information, code domain resource information, time domain resource offset information, frequency domain resource offset information, and code domain resource offset information.

[0027] Based on the above two possible implementations, the terminal device can receive the first signal on the resource indicated by the second indication information, which can avoid interference between the received first signal and other signals (first signals received by other terminal devices) as much as possible, and can improve the reliability of communication; in addition, the network device can dynamically instruct the terminal device to receive the resource of the first signal according to the actual communication scenario or communication situation, which can avoid the situation where multiple terminal devices receive the first signal on the same resource, causing resource congestion, as much as possible, which is conducive to meeting the load balancing requirements of the network device and can improve the flexibility of determining resources.

[0028] In one possible implementation, the terminal device receives third indication information, and receives the first signal according to the third indication information, wherein the third indication information is used to instruct the terminal device to receive beam information associated with the first signal.

[0029] Based on this possible implementation, the terminal device can receive the first signal based on one or more beams indicated by the third indication information. In addition, the network device can dynamically instruct the terminal device to receive the beam associated with the first signal according to the actual communication scenario or communication situation, which can improve the flexibility of determining the beam associated with the first signal.

[0030] In one possible implementation, the terminal device sends a first request message to the core network device; or sends a first request message to the network device; wherein the first request message is used to request to receive a first signal.

[0031] Based on this possible implementation, the terminal device can actively request the network device to send a first signal, which can effectively solve the situation where the terminal device needs to receive the first signal but the network device does not allow / support activation of the second receiver of the terminal device, thereby improving communication performance.

[0032] In one possible implementation, the terminal device receives a first response message from a core network device; or receives a first response message from a network device; wherein the first response message is used to indicate one or more of the following: whether the network device supports the terminal device to activate the second receiver, whether the network device allows the terminal device to activate the second receiver, and the resources for the terminal device to receive the first signal.

[0033] Based on this possible implementation, the terminal device can determine whether the network device allows / supports activation of the second receiver of the terminal device based on the first response information. In addition, when the first response information indicates the resources for the terminal device to receive the first signal, the terminal device can determine to activate the second receiver and at the same time determine the resources for receiving the first signal, thereby avoiding interference between the received first signal and other signals as much as possible and improving communication reliability. For example, the network device may expect to modulate the first signal only according to a certain modulation method, but also support modulation of the first signal according to other modulation methods. In this way, even if the second receiver of the terminal device is not compatible with the first signal modulated according to the modulation method expected by the network device, the terminal device can request the network device to send the first signal suitable for its own second receiver.

[0034] In one possible implementation, the terminal device sends the capability information of the terminal device to the core network device; or, sends the capability information of the terminal device to the network device; wherein the capability information of the terminal device is used to indicate one or more of the following: the demodulation mode supported by the second receiver of the terminal device, the operating frequency supported by the terminal device, the number of operating frequencies supported by the terminal device, and the number of beams supported by the terminal device.

[0035] Based on this possible implementation, the terminal device can send the capability information of the terminal device to the core network device or the network device, so that the network device or the core network device can determine whether the network device allows / supports activating the second receiver of the terminal device. At the same time, it can assist the network device or the core network device in determining the first indication information, which can effectively improve the efficiency of information interaction between the terminal device and the network device, thereby improving communication performance.

[0036] In a second aspect, a communication method is provided, which can be executed by a network device. Unless otherwise specified, the "network device" in this application can refer to the network device itself, or a component in the network device (for example, a processor, a chip, or a chip system, etc.), or a logic module or software that can implement all or part of the functions of the network device. The method includes: the network device sends a first indication information; wherein the first indication information is used to indicate one or more of the following: the modulation mode of the first signal, the number of sequences superimposed on the first signal, whether the network device supports activating the second receiver of the terminal device, and whether the network device allows activation of the second receiver of the terminal device; the first signal is used to wake up the first receiver of the terminal device; the power consumption of the first receiver is greater than the power consumption of the second receiver.

[0037] Herein, used to indicate can be understood as used to determine, or can be understood as including.

[0038] Based on this scheme, the first indication information can indicate the modulation mode of the first signal, and the terminal device can determine whether to activate the second receiver by determining whether the demodulation mode of the second receiver is the demodulation mode corresponding to the modulation mode of the first signal; or, the first indication information can indicate the number of sequences superimposed on the first signal, and the terminal device can determine the modulation mode of the first signal based on the number of sequences superimposed on the first signal, and can determine whether to activate the second receiver by determining whether the demodulation mode of the second receiver is the demodulation mode corresponding to the modulation mode of the first signal; or, the first indication information can directly indicate the terminal device whether to activate the second receiver.

[0039] In this manner, a network device can instruct a terminal device of the same type to activate a second receiver. This allows the network device to transmit a first signal regardless of the terminal device type, thereby reducing operational complexity and improving operational efficiency. Furthermore, this manner can minimize situations where the terminal device attempts to receive the first signal even though it cannot resolve it when activating the second receiver, effectively reducing power consumption. Alternatively, in this manner, if the terminal device determines it cannot resolve the first signal, it can directly place the second receiver into a dormant state, effectively reducing power consumption.

[0040] In one possible implementation, the first indication information is used to indicate one or more of the following: the network device allows activation of the second receiver of the terminal device, the network device does not allow activation of the second receiver of the terminal device, the network device supports activation of the second receiver of the terminal device, the network device does not support activation of the second receiver of the terminal device, the type of terminal device that the network device allows activation of the second receiver, the type of terminal device that the network device does not allow activation of the second receiver, the type of terminal device that the network device supports activation of the second receiver, the type of terminal device that the network device does not support activation of the second receiver, the time period during which the network device allows activation of the second receiver of the terminal device, the time period during which the network device does not allow activation of the second receiver of the terminal device, the time period during which the network device supports activation of the second receiver of the terminal device, the time period during which the network device does not support activation of the second receiver of the terminal device, the working frequency supported by the network device, the maximum number of working frequencies supported by the terminal device supported by the network device, resources supported by the network device for sending the first signal, the terminal device that the network device allows supporting the working frequency to receive the first signal, the working frequency supported by the network device is less than the first preset frequency, and the working frequency supported by the network device is greater than the second preset frequency.

The network device can send a first message to instruct multiple terminal devices to determine whether to activate the second receiver, which can effectively reduce the transmission overhead. At the same time, it can effectively reduce the load of the network device and improve the working efficiency of the network device.

[0044] Among them, the first indication information can indicate a time period so that the terminal device can determine the time period for activating the second receiver and the time period for not activating the second receiver. This can ensure that the terminal device successfully parses the received first signal during the time period when the second receiver is activated, and can also ensure that the network device does not send the first signal to the terminal device during the time period when the second receiver is not activated, thereby improving the efficiency of information interaction between the terminal device and the network device. In addition, the network device can dynamically indicate the time period for activating the second receiver of the terminal device according to the actual communication scenario or communication situation. By configuring different time periods, different types of terminal devices can activate the second receiver in different time periods, which can meet the load balancing requirements of the network device and improve the flexibility of determining the time period.

[0045] The first indication information may indicate the capability of the network device to serve the terminal device (such as the frequency supported by the network device) so that the terminal device can determine whether to activate the second receiver.

[0046] In one possible implementation, the network device receives first indication information from the core network device; or receives first information from the core network device; determines the first indication information based on the first information; wherein the first information is used to indicate a modulation method of the first signal.

[0047] Based on this possible implementation, several feasible solutions are provided for determining the first indication information.

[0048] In one possible implementation, the network device sends second indication information; wherein the second indication information is used to indicate the resources for the terminal device to receive the first signal.

[0049] In one possible implementation, the second indication information includes one or more of the following: time domain resource information, frequency domain resource information, code domain resource information, time domain resource offset information, frequency domain resource offset information, and code domain resource offset information.

[0050] Based on the above two possible implementations, the terminal device can receive the first signal on the resource indicated by the second indication information, which can avoid interference between the first signal received by the terminal device and other signals (first signals received by other terminal devices) as much as possible, and can improve the reliability of communication; in addition, the network device can dynamically instruct the terminal device to receive the resource of the first signal according to the actual communication scenario or communication situation, which can avoid the situation where multiple terminal devices receive the first signal on the same resource and cause resource congestion as much as possible, which is conducive to meeting the load balancing requirements of the network device and can improve the flexibility of determining resources.

[0051] In one possible implementation, the network device sends a third indication information; wherein the third indication information is used to instruct the terminal device to receive beam information associated with the first signal.

[0052] Based on this possible implementation, the terminal device can receive the first signal based on one or more beams indicated by the third indication information. In addition, the network device can dynamically instruct the terminal device to receive the beam associated with the first signal according to the actual communication scenario or communication situation, which can improve the flexibility of determining the beam associated with the first signal.

[0053] In one possible implementation, the network device receives first request information from the terminal device; or, the network device receives first request information from the core network device; wherein the first request information is used to request reception of a first signal.

[0054] Based on this possible implementation, the terminal device can request the network device to send a first request message, which can effectively solve the situation where the terminal device needs to receive the first signal but the network device does not allow / support activation of the second receiver of the terminal device, thereby improving communication performance.

[0055] In one possible implementation, the network device sends a first response message to the terminal device; or, the network device sends a first response message to the core network device; wherein the first response message is used to indicate one or more of the following: whether the network device supports the terminal device to activate the second receiver, whether the network device allows the terminal device to activate the second receiver, and the resources for the terminal device to receive the first signal.

[0056] Based on this possible implementation, the terminal device can determine whether the network device allows / supports activation of the second receiver of the terminal device based on the first response information; in addition, when the first response information indicates the resources for the terminal device to receive the first signal, the terminal device can determine to activate the second receiver and at the same time determine the resources for receiving the first signal, thereby avoiding interference between the first signal received by the terminal device and other signals as much as possible, and improving the reliability of communication. For example, the network device may expect to modulate the first signal only according to a certain modulation method, but also support modulation of the first signal according to other modulation methods. In this way, even if the second receiver of the terminal device is not compatible with the first signal modulated according to the modulation method expected by the network device, the terminal device can request the network device to send the first signal suitable for its own second receiver.

[0057] In one possible implementation, the network device receives capability information from the terminal device; or the network device receives capability information of the terminal device from the core network device; and determines the first indication information based on the capability information of the terminal device. The capability information of the terminal device is used to indicate one or more of the following: a demodulation mode supported by the second receiver of the terminal device, operating frequencies supported by the terminal device, the number of operating frequencies supported by the terminal device, and the number of beams supported by the terminal device.

[0059] In combination with the first aspect and the second aspect, in one possible implementation, the second receivers of different types of terminal devices support different demodulation modes.

[0060] In combination with the first aspect and the second aspect, a possible implementation is that different types of terminal devices correspond to different first parameters; wherein the first parameter is one or more of the following: the maximum number of bits of the first signal supported by the terminal device, the number of sequences supported for demodulation by the terminal device, the resource information supported by the terminal device for receiving the first signal, the operating frequency supported by the terminal device, the type of synchronization signal supported by the terminal device for receiving, the operating time period supported by the terminal device, the transmission bandwidth supported by the terminal device, the maximum baseband bandwidth supported by the terminal device, the maximum radio frequency bandwidth supported by the terminal device, and the maximum data rate supported by the terminal device.

[0061] Based on this possible implementation, the type of terminal device in this application can be distinguished based on one or more of the above parameters, so that the network device can determine the capabilities of the terminal device based on the above parameters, and then determine whether the second receiver of the terminal device is activated based on the capabilities of the terminal device.

[0062] It can be understood that when there are multiple types of terminal devices in a communication system or cell, the network device can indicate which type of terminal device is allowed / supported to activate the second receiver by sending at least one first indication information, so as to ensure as much as possible that the terminal device that activates the second receiver can successfully parse the first signal, thereby improving the reliability of communication.

[0063] In combination with the first aspect and the second aspect, in one possible implementation, the first signal is a low-power wake-up signal.

The second receiver can always be in the awake state, and while receiving the first signal in a timely manner, it can reduce the power consumption of the terminal device.

[0067] In combination with the first aspect and the second aspect, a possible implementation is that the modulation method of the first signal is orthogonal frequency division multiplexing (OFDM) modulation method; or, the modulation method of the first signal is on-off key control (OOK) modulation method; wherein, the amplitude of the first signal corresponding to each preset time unit is non-zero.

[0068] Based on this possible implementation, several feasible solutions are proposed for the implementation of the modulation method of the first signal. By modulating the first signal based on the above modulation method, the first signal occupies fewer resources and can improve resource utilization; at the same time, the terminal device can obtain a valid signal in each preset time unit, and can analyze the first signal through the correlation detection method. Compared with envelope detection, correlation detection has better coverage.

[0069] On the third aspect, a communication method is provided, which can be executed by a terminal device.

[0071] In a fourth aspect, a communication method is provided, which can be executed by a network device. Unless otherwise specified, the "network device" in this application can refer to the network device itself, or a component in the network device (for example, a processor, a chip, or a chip system, etc.), or a logic module or software that can implement all or part of the network device functions. The method includes: the network device receives capability information from the terminal device; or, receives capability information of the terminal device from the core network device; and determines first indication information based on the capability information of the terminal device.

[0072] Based on this solution, the network device can determine the first indication information based on the capability information of the terminal device. That is, the network device can determine whether the terminal device can successfully parse the first signal based on the capability information of the terminal device, and further determine whether to allow / support activation of the second receiver of the terminal device, thereby improving the accuracy of the network device's determination of the first indication information. In addition, it can ensure to the greatest extent possible that the terminal device can successfully parse the received first signal when the second receiver is activated, thereby improving the reliability of communication. For example, the network device supports modulating the first signal using multiple modulation methods, but can determine which modulation method or methods to use to modulate the first signal based on the capability information of the terminal devices present in the cell, and send the corresponding first indication information.

The following description of the embodiments of this application does not constitute a limitation on the scope of protection of this application.

[0126] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction to the relevant technologies of the present application is first given as follows.

[0127] 1) Communication system

[0128] Among them, the design and development targets of the fifth generation (5G) mobile communication system are terminal devices and vertical usage scenarios (i.e., integrating the fourth generation (4G) mobile communication system, etc.).

[0129] In addition to requiring low latency, high reliability, and high feasibility, terminal devices also require low energy consumption. For example, the power consumption of a terminal device in the radio resource control (RRC) idle state or RRC inactive state may be tens of milliwatts, and in the RRC connected state may be hundreds of milliwatts.

[0130] It is understandable that for terminal devices without continuous energy sources, such as terminal devices using small rechargeable batteries and single-coin batteries, energy consumption needs to be reduced as much as possible; or, in vertical usage scenarios, such as sensors and actuators are widely deployed for measurement, charging, etc., and the batteries of sensors and actuators are usually non-rechargeable, power consumption needs to be reduced as much as possible to ensure that they can work for at least one year; or, in some IoT scenarios, wearable devices (such as smart watches, rings, electronic health-related devices and medical monitoring equipment) need to improve battery life while maintaining performance.

[0131] 2) Power consumption

[0132] The power consumption may depend on the interval of the wake-up cycle. For example, when the terminal device is in the RRC idle state, the terminal device may monitor paging messages. If the period during which the terminal device monitors paging messages is longer, the terminal device may have more time to enter the sleep state, thereby reducing power consumption.

[0133] Exemplarily, the terminal device can determine the wake-up time based on an extended discontinuous reception (eDRX) cycle or discontinuous reception (DRX). For example, the terminal device can wake up once according to the DRX period. When the terminal device is in the awake state, it can monitor paging messages or implement the transmission of signaling and data services.

[0134] However, if a terminal device does not transmit signaling or data services during its wake-up period, it is in an ineffective wake-up state, which increases its power consumption. Furthermore, a terminal device in a dormant state cannot respond to network devices. This means that when a network device pages or sends signaling to a dormant terminal device, the terminal device cannot receive it. For example, in a fire detection and extinguishing scenario, within 1 to 2 seconds after a sensor detects a fire, fire shutters should be closed and an actuator should open a fire sprinkler. However, when the actuator is in a dormant state, it cannot receive the signaling to open the fire sprinkler, resulting in losses.

[0135] Therefore, it is possible to consider waking up the terminal device only when signaling or data services need to be transmitted.

[0136] In one possible implementation, a terminal device may include a low power wake-up receiver (LP-WUR) and a main receiver, where the LP-WUR consumes less power than the main receiver. The main receiver is used to transmit data and signaling. When data and signaling transmission is not required, the main receiver can be turned off or put into deep sleep. The LP-WUR can be in an awake state and determine whether to wake up the main receiver based on a received low power wake-up signal (LP-WUS).

[0137] Among them, the terminal device receives LP-WUS through LP-WUR, which can ensure that the terminal device receives LP-WUS from the network device and responds to the network device at any time, which can improve the reliability of communication and effectively reduce the power consumption of the terminal device.

[0138] It is understandable that LP-WUR can be used for small terminal devices that are sensitive to power (such as industrial sensors, controllers, or wearable devices in IoT scenarios), or LP-WUR can be used for terminal devices in wireless scenarios (such as smart glasses, smartphones, etc.) without restriction.

[0139] For example, the specific steps of LP-WUR determining whether to wake up the main receiver may be as shown in FIG1 below:

[0140] S101. LP-WUR receives LP-WUS from a network device.

[0141] S102. LP-WUR determines whether to wake up the main receiver according to LP-WUS.

[0142] Among them, when the bit value corresponding to LP-WUS is the same as the preset bit value, LP-WUR determines to wake up the main receiver (that is, S103 can be executed); or, when the bit value corresponding to LP-WUS is different from the preset bit value, LP-WUR determines not to wake up the main receiver (that is, S104 can be executed).

[0143] 3) LP-WUS

[0144] Among them, LP-WUS can be modulated according to the following three methods.

[0145] The first modulation method, LP-WUS can be modulated according to the OOK modulation method.

[0146] LP-WUS can be mapped to the time domain based on whether a signal is present or absent. The waveform of LP-WUS mapped to the time domain can be shown in FIG2(a). That is, the absence of a signal can be represented by a bit state of 0, and the presence of a signal can be represented by a bit state of 1. FIG2(a) can represent that the bit value corresponding to LP-WUS is '1001'.

[0147] Optionally, Manchester coding can be introduced to reduce the false detection rate (e.g., detecting a noise signal as a useful signal will increase the false detection rate). That is, the state of one bit can be determined by comparing the energy of the two parts before and after. As shown in (b) of Figure 2, the waveform of the LP-WUS mapping in the time domain can be divided into four parts. The energy of the first part and the second part can be compared, and the energy of the third part and the fourth part can be compared. Since the energy of the first part is greater than the energy of the second part, the bit state corresponding to the first and second parts can be 0; since the energy of the third part is less than the energy of the fourth part, the bit state corresponding to the third and fourth parts can be 1.

[0148] It can be understood that the LP-WUR with envelope detection capability can demodulate the above-mentioned modulated LP-WUS. As shown in Figure 3, the LP-WUR can filter out the signal of each part (for example, a symbol) through the envelope detector, that is, when the LP-WUR receives the modulated LP-WUS, it can filter out the signal of each part through the envelope detector (that is, the envelope detector can obtain all the information of the LP-WUS), and then the filtered signal can be baseband processed through DBB to obtain the demodulated LP-WUS.

[0149] The second modulation method, LP-WUS can be modulated according to the OFDM modulation method.

[0150] The mapping method of LP-WUS can be as shown in Figure 4. That is, a portion of the information can be carried using either a signal or no signal, and another portion of the information can be carried using different sequences on the signal. Different sequences on the signal can be distinguished by different bit values, such as sequence 0 with a bit value of 00, sequence 1 with a bit value of 01, sequence 2 with a bit value of 10, and sequence 3 with a bit value of 11.

[0151] It can be understood that, as shown in Figure 5, the LP-WUR with correlation detection capability can first filter out the signal of each part through the envelope detector (that is, obtain partial information), and then distinguish the sequence of the filtered signal through the DBB (that is, obtain another part of the information). For example, the DBB can perform correlation calculations on the sequence of the filtered signal and the locally stored sequence to determine the sequence. Furthermore, the DBB can also perform correlation calculations on all the information to obtain the demodulated LP-WUS.

[0152] Compared with the first modulation method, the second modulation method can occupy less time domain resources. At the same time, in the second modulation method, LP-WUR can perform correlation calculations on the received signal and the locally stored sequence, which can improve the detection performance.

[0153] The third modulation method, LP-WUS can be modulated according to OOK modulation method and OFDM modulation method.

[0154] The mapping method of LP-WUS may be as shown in FIG6 , where LP-WUS may be mapped once through the first modulation method, and then mapped once through the second modulation method.

[0155] It can be understood that the third modulation method occupies the same time domain resources as the first modulation method, and the third modulation method occupies more time domain resources than the second modulation method.

[0156] When the LP-WUS is modulated using the third modulation method, any LP-WUR can demodulate the modulated LP-WUS. As shown in Figure 6, the LP-WUR with envelope detection capability can filter out the signal of each part (for example, a symbol) to obtain the bit value '1010', and the LP-WUR with correlation detection capability can distinguish the sequence carried by the signal to obtain the bit value '10' of the sequence.

[0157] Based on the descriptions of the three modulation methods described above, when a network device modulates an LP-WUS using the first modulation method, the LP-WUR in Figure 5 cannot parse the LP-WUS. Alternatively, when a network device modulates an LP-WUS using the second modulation method, the LP-WUR in Figure 3 cannot parse the LP-WUS. In other words, when the LP-WUR cannot parse the LP-WUS but receives it, it increases the power consumption of the terminal device.

[0158] In addition, when the demodulation capabilities of the terminal devices in the cell are different (which can be understood as different types of terminal devices), if the time domain resources are limited, the network device may expect to modulate LP-WUS only according to the second modulation method, but the network device cannot only allow a certain type of terminal device to access the cell, or the network device may only support the use of the first modulation method or the second modulation method to modulate LP-WUS, and thus does not support a certain type of terminal device to access the cell. At this time, when the terminal device blindly attempts to access the cell, it will not only fail to successfully access the cell but also increase unnecessary energy consumption.

[0159] Therefore, how to reduce the power consumption of terminal equipment has become an urgent problem to be solved.

[0160] To address the above-mentioned technical issues, the present application provides a communication method, comprising: a terminal device receiving first indication information; and determining whether to activate a second receiver based on the first indication information. The first indication information is used to indicate one or more of the following: a modulation mode of a first signal, a number of sequences superimposed on the first signal, whether a network device supports activation of the second receiver of the terminal device, or whether the network device allows activation of the second receiver of the terminal device; the first signal is used to wake up the first receiver of the terminal device; and the power consumption of the first receiver is greater than the power consumption of the second receiver.

[0161] In an embodiment of the present application, the first indication information may indicate the modulation mode of the first signal, and the terminal device may determine whether to activate the second receiver by determining whether the demodulation mode of the second receiver is the demodulation mode corresponding to the modulation mode of the first signal; or, the first indication information may indicate the number of sequences superimposed on the first signal, and the terminal device may determine the modulation mode of the first signal based on the number of sequences superimposed on the first signal, and may determine whether to activate the second receiver by determining whether the demodulation mode of the second receiver is the demodulation mode corresponding to the modulation mode of the first signal; or, the first indication information may directly indicate whether the terminal device activates the second receiver.

[0162] The terminal device can determine, based on the first indication information, whether the second receiver of the terminal device can successfully parse the first signal, and then determine whether to activate the second receiver. In this manner, when the terminal device activates the second receiver, it can minimize the possibility of the terminal device attempting to receive the first signal despite being unable to parse it, thereby effectively reducing the power consumption of the terminal device. Alternatively, in this manner, when the terminal device determines that it cannot parse the first signal, it can directly put the second receiver into a dormant state, thereby effectively reducing the power consumption of the terminal device.

[0163] In the embodiment of the present application, "indication" may include direct indication, indirect indication, explicit indication, implicit indication, and the like. When describing that a certain indication information is used to indicate A, it can be understood that the indication information carries A, carries the identifier of A, carries B that is associated with A, carries the identifier of B that is associated with A, and so on. In other words, if the receiving side of a certain indication information can determine A based on the indication information, it can be described as the indication information indicating A, and the specific determination method is not limited. When it is understood that the indication information carries A, "indication" can be replaced with "includes". At this time, a statement similar to "send / receive indication information, the indication information is used to indicate A" can be replaced with "send / receive A".

Specifically, the network device can be a device that supports wired access or a device that supports wireless access.

[0176] For example, the network device may include an evolved NodeB (eNB) or e-NodeB in an LTE system or an enhanced LTE (LTE-advanced, LTE-A) system, such as a traditional macro eNB and a micro eNB in ​​a heterogeneous network scenario. Alternatively, it may include a next-generation node B (gNB) in an NR system. Alternatively, it may include a transmission reception point (TRP), a home base station (e.g., a home evolved NodeB, or home Node B, HNB), a baseband unit (BBU), a baseband pool (BBU pool), or a Wi-Fi access point (AP).

Alternatively, the network device may be a device that implements a base station function in IoT, such as a device that implements a base station function in drone communication, V2X, D2D, or machine to machine (M2M).

[0177] A network device may also be a module or unit that implements some of the functions of a base station. For example, a network device may be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU).

[0178] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, the network device may be a network device or a module of a network device in an open radio access network (open RAN, ORAN) system. In the ORAN system, CU may also be referred to as open (open, O)-CU, DU may also be referred to as O-DU, CU-CP may also be referred to as O-CU-CP, CU-UP may also be referred to as O-CU-UP, and RU may also be referred to as O-RU.

[0181] It is understandable that network devices and terminal devices, as well as terminal devices and terminal devices, can communicate through authorized spectrum, through unlicensed spectrum, or through both authorized spectrum and unlicensed spectrum. Network devices and terminal devices, as well as terminal devices and terminal devices, can communicate through spectrum below 6G, through spectrum above 6G, or through spectrum below 6G and spectrum above 6G at the same time. The embodiments of the present application do not limit the spectrum resources used between network devices and terminal devices.

[0182] It is understood that the embodiments of the present application can be applied to downlink signal transmission, uplink signal transmission, and D2D signal transmission.

[0185] Among them, the AMF network element is used to implement access management and other functions.

[0186] It should be noted that the communication system described in the embodiment of the present application is intended to more clearly illustrate the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided in the embodiment of the present application. Ordinary technicians in this field can know that with the evolution of network architecture and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0187] In specific implementations, the various terminal devices, network devices, and core network devices shown in Figure 7 may all adopt the structure shown in Figure 8, or include the components shown in Figure 8. Figure 8 is a schematic diagram of the structure of a communication device 80 provided in an embodiment of the present application. The communication device 80 may be a terminal device or a chip or system-on-chip in a terminal device; it may also be a network device or a chip or system-on-chip in a network device; it may also be a core network device or a chip or system-on-chip in a core network device.

Furthermore, the communication device 80 may also include a communication bus 802 and at least one communication interface ( FIG8 is merely exemplary, illustrating the communication device 80 including a communication interface 804 and one processor 801). Optionally, the communication device 80 may also include a memory 803.

[0189] Processor 801 can be a general-purpose central processing unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits for controlling the execution of the program of the present application, or a processing core for processing data (e.g., computer program instructions). The processor can be a single-core (single-CPU) processor or a multi-core (multi-CPU) processor.

[0190] In a specific implementation, as an embodiment, the processor 801 may include one or more CPUs, such as CPU0 and CPU1 in FIG8 .

[0191] The communication bus 802 may be a Peripheral Component Interconnect (PCI) bus or an Extended Industry Standard Architecture (EISA) bus, for example. This bus may be classified as an address bus, a data bus, a control bus, or the like. For ease of illustration, FIG8 shows only one thick line, but this does not imply that there is only one bus or type of bus. The communication bus 802 is used to connect the various components within the communication device 80, enabling communication and interaction between the various components within the communication device 80.

[0192] The communication interface 804 may be a transceiver module for communicating with other devices or a communication network, such as Ethernet, a radio access network (RAN), or a wireless local area network (WLAN). For example, the communication interface 804 may be a device such as a transceiver or a transceiver. Alternatively, the communication interface 804 may be a transceiver circuit within the processor 801 for implementing signal input and output to the processor.

[0193] The memory 803 may be a device having a storage function. For example, it may be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM) or other types of dynamic storage devices that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compact disc, laser disc, optical disc, digital versatile disc, Blu-ray disc, etc.), a magnetic disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto. The memory may exist independently and be connected to the processor via a communication bus 802. The memory may also be integrated with the processor.

[0194] Exemplarily, the memory 803 is used to store computer-executable instructions for executing the solution of the present application, and the execution is controlled by the processor 801. The processor 801 is used to execute the computer-executable instructions stored in the memory 803, thereby implementing the method provided in the embodiment of the present application.

[0195] Alternatively, optionally, in an embodiment of the present application, the processor 801 may also perform processing-related functions in the method provided in the following embodiments of the present application, and the communication interface 804 is responsible for communicating with other devices or communication networks, which is not specifically limited in the embodiments of the present application.

[0196] Optionally, the computer-executable instructions in the embodiments of the present application may also be referred to as application code, which is not specifically limited in the embodiments of the present application.

[0197] In a specific implementation, as an embodiment, the communication device 80 may further include an output device 805 and an input device 806. The output device 805 communicates with the processor 801 and can display information in a variety of ways.

The input device 806 communicates with the processor 801 and can receive user input in a variety of ways. For example, the input device 806 can be a mouse, a keyboard, a touch screen device, or a sensor device.

[0198] It should be noted that the composition structure shown in Figure 8 does not constitute a limitation on the communication device. In addition to the components shown in Figure 8, the communication device may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0199] The communication method provided by the embodiment of the present application will be described below in conjunction with the accompanying drawings. It will be understood that in the embodiment of the present application, the terminal device or the network device can perform some or all of the steps in the embodiment of the present application, and these steps or operations are only examples. The embodiment of the present application can also perform other operations or variations of various operations. In addition, the various steps can be performed in different orders presented in the embodiment of the present application, and it is possible that not all operations in the embodiment of the present application need to be performed.

[0200] As shown in Figure 9, an interaction diagram of a communication method provided by the present application is provided. The steps performed by a single execution subject (for example, a terminal device or a network device) in the embodiment of the present application can also be divided into multiple execution subjects, which can be logically and / or physically separated. For example, referring to Figure 9, the communication method includes the following steps:

[0201] S901. The network device sends first indication information to the terminal device; correspondingly, the terminal device receives the first indication information from the network device.

[0202] The terminal device includes a first receiver and a second receiver.

[0203] The first receiver is used for transmitting data services or signaling between the terminal device and the network device; the second receiver is used for the terminal device to receive the first signal (ie, the first signal is used to wake up the first receiver).

[0204] Optionally, the first signal may be a low-power wake-up signal, or the first signal may be any other signal that can wake up the first receiver of the terminal device, without limitation.

[0205] It can be understood that when the first signal is a low-power wake-up signal, the second receiver of the terminal device can receive the first signal at a lower receiving power, which can effectively reduce the power consumption of the terminal device.

[0206] Optionally, the second receiver may be a low-power wake-up receiver, or the second receiver may be any other receiver that can receive the first signal, without limitation.

[0207] Among them, the first indication information is used to indicate one or more of the following: the modulation method of the first signal, the number of sequences superimposed by the first signal, whether the network device supports activating the second receiver of the terminal device, and whether the network device allows activation of the second receiver of the terminal device.

[0208] Herein, used to indicate can be understood as used to determine, or can be understood as including.

[0209] 1) Modulation method of the first signal

[0210] Optionally, the modulation mode of the first signal may be an OOK modulation mode, an OFDM modulation mode, or a combination of the OOK modulation mode and the OFDM modulation mode, without limitation.

[0211] The modulation mode of the first signal may be an OOK modulation mode, and the amplitude of the first signal corresponding to each preset time unit is non-zero.

[0212] It is understandable that the first signal may be an “all-ON” signal, and may be modulated using the two modulation modes mentioned above (ie, the OOK modulation mode and the OFDM modulation mode).

[0213] It can be understood that, when the first indication information indicates the modulation mode of the first signal, the first indication information may indicate the index of the modulation mode of the first signal, or the first indication information may be a bit map.

[0214] In one example, taking the index of the modulation mode of the first signal indicated by the first indication information as an example, assuming that there are three modulation modes, the index of the first modulation mode is 0, the index of the second modulation mode is 1, and the index of the third modulation mode is 2, then the first indication information can indicate a modulation mode of the first signal through two bits. That is, when the bit value is 00, it can indicate that the index of the modulation mode of the first signal is 0, and the modulation mode of the first signal is the first modulation mode; when the bit value is 01, it can indicate that the index of the modulation mode of the first signal is 1, and the modulation mode of the first signal is the second modulation mode; when the bit value is 10, it can indicate that the index of the modulation mode of the first signal is 2, and the modulation mode of the first signal is the third modulation mode; when the bit value is 0001, it can indicate that the index of the modulation mode of the first signal is 0 and 1, and the modulation mode of the first signal is the first modulation mode and the second modulation mode; when the bit value is 0010, it can indicate that the index of the modulation mode of the first signal is 0 and 2, and the modulation mode of the first signal is the first modulation mode and the third modulation mode; when the bit value is 000110, it can indicate that the index of the modulation mode of the first signal is 0, 1, and 2, and the modulation mode of the first signal is the first modulation mode, the second modulation mode, and the third modulation mode.

[0215] In another example, taking the first indication information as a bit map (each bit in the bit map corresponds to a modulation mode of the first signal) as an example, assuming that there are three modulation modes, the bit map can occupy three bits. When the bit map is 100, it can indicate that the modulation mode of the first signal is the first modulation mode; when the bit map is 010, it can indicate that the modulation mode of the first signal is the second modulation mode; when the bit map is 001, it can indicate that the modulation mode of the first signal is the third modulation mode; when the bit map is 110, it can indicate that the modulation mode of the first signal is the first modulation mode and the second modulation mode; when the bit map is 101, it can indicate that the modulation mode of the first signal is the first modulation mode and the third modulation mode; when the bit map is 111, it can indicate that the modulation mode of the first signal is the first modulation mode, the second modulation mode, and the third modulation mode.

[0216] 2) The number of sequences carried by the first signal

[0217] In which, the number of sequences carried by the first signal can also be understood as the number of sequences supported by the first signal, or, it can also be understood as the number of sequences carried by the first signal in each time unit in at least one time unit, or, it can also be understood as the number of sequences supported by the first signal in each time unit in at least one time unit, or, it can also be understood as the maximum number of sequences supported (or carried) by the first signal in each time unit with a signal in at least one signal, or, it can also be understood as the number of sequences supported (or carried) by the first signal in each time unit with a signal in at least one signal, or, it can also be understood as the maximum number of sequences supported (or carried) by the first signal in each time unit with a signal in at least one signal.

[0218] It can be understood that the first signal can carry a sequence within at least one time unit with a signal. The sequence can be a specific known sequence or a sequence selected from at least two sequences (such as one of four sequences, in which case the number of sequences carried by the first signal is 4).

[0219] The time unit may be one symbol, 1 / 2 symbol, 1 / 4 symbol, or at least two symbols; or, the time unit may be one or more of the following: subframe, frame, time slot, millisecond (ms), or second (s).

[0220] The symbol may be one or more of the following: OFDM symbol, OOK symbol.

[0221] When the first indication information indicates the number of sequences carried by the first signal, the first indication information may indicate the number of sequences carried by the first signal through a bit value.

[0222] In one example, taking the first indication information occupying two bits as an example, when the bit value is 00, it can indicate that the number of sequences carried by the first signal is 1; when the bit value is 01, it can indicate that the number of sequences carried by the first signal is 2; when the bit value is 10, it can indicate that the number of sequences carried by the first signal is 3; when the bit value is 11, it can indicate that the number of sequences carried by the first signal is 4.

[0223] In another example, taking the first indication information occupying 3 bits as an example, when the bit value is 000, it can indicate that the number of sequences carried by the first signal is 1; when the bit value is 001, it can indicate that the number of sequences carried by the first signal is 2; when the bit value is 010, it can indicate that the number of sequences carried by the first signal is 3; when the bit value is 011, it can indicate that the number of sequences carried by the first signal is 4;...; when the bit value is 111, it can indicate that the number of sequences carried by the first signal is 8.

[0224] 3) Does the network device support activating the second receiver of the terminal device?

[0225] Here, activation can be described as turning on, entering, or accessing, without any restriction.

[0226] Exemplarily, when the first indication information indicates whether the network device supports activating the second receiver of the terminal device, the first indication information may occupy one bit. When the bit value is 1, it may indicate that the network device supports activating the second receiver of the terminal device; when the bit value is 0, it may indicate that the network device does not support activating the second receiver of the terminal device. Alternatively, when the bit value is 0, it may indicate that the network device supports activating the second receiver of the terminal device; when the bit value is 1, it may indicate that the network device does not support activating the second receiver of the terminal device.

[0227] 4) Whether the network device allows activation of the second receiver of the terminal device

[0228] Exemplarily, when the first indication information indicates whether the network device allows activation of the second receiver of the terminal device, the first indication information may occupy one bit. When the bit value is 1, it may indicate that the network device allows activation of the second receiver of the terminal device; when the bit value is 0, it may indicate that the network device does not allow activation of the second receiver of the terminal device. Alternatively, when the bit value is 0, it may indicate that the network device allows activation of the second receiver of the terminal device; when the bit value is 1, it may indicate that the network device does not allow activation of the second receiver of the terminal device.

[0229] It is understandable that "support" and "allow" have different meanings. That is, as long as the network device does not allow activation of the terminal device's second receiver, there is no possibility of activating the terminal device's second receiver. However, if the network device allows activation of the terminal device's second receiver, it indicates that the network device is capable of serving the terminal device, and can either directly activate the terminal device's second receiver or use it as a prerequisite for activation. For example, the network device can choose whether to support activation of the terminal device's second receiver under the prerequisite of allowing. That is, the network device can indicate activation of the terminal device's second receiver by indicating support, or indicate non-activation of the terminal device's second receiver by indicating non-support.

[0230] For example, taking the first indication information occupying two bits as an example, the first bit can indicate whether the network device allows activation of the second receiver of the terminal device, and the second bit can indicate whether the network device supports activation of the second receiver of the terminal device. When the bit value of the first bit is 0, it can indicate that the network device does not allow activation of the second receiver of the terminal device, and the second bit is reserved; when the bit value of the first bit is 1, it can indicate that the network device allows activation of the second receiver of the terminal device. In this case, when the bit value of the second bit is 0, it can indicate that the network device does not support activation of the second receiver of the terminal device; when the bit value of the second bit is 1, it can indicate that the network device supports activation of the second receiver of the terminal device.

[0231] Among them, whether the network device supports / allows activation of the second receiver of the terminal device can also be described as one or more of the following: whether the network device supports / allows the LP-WUS feature, whether the network device supports / allows access of the terminal device, whether the network device supports / allows access of a certain type of terminal device, whether the network device supports / allows access of terminal devices with receivers having envelope detection capabilities, whether the network device supports / allows access of terminal devices with receivers having OFDM signal detection capabilities (which can also be understood as correlation detection capabilities, sequence detection capabilities, phase information acquisition capabilities, etc.), whether the network device supports / allows sending LP-WUS, whether the network device supports / allows the terminal device to enter low power consumption mode, whether the network device supports / allows turning off the second receiver of the terminal device, and whether the network device supports / allows the second receiver of the terminal device to enter a deep sleep state.

[0232] It is understandable that the first indication information may indicate one of the above four types of information (i.e., the modulation mode of the first signal, the number of sequences carried by the first signal, whether the network device supports activation of the second receiver of the terminal device, and whether the network device allows activation of the second receiver of the terminal device), any two of the above four types of information, any three of the above four types of information, or all of the above four types of information. This application proposes four possible embodiments:

[0233] In a first possible embodiment, the first indication information may indicate the modulation mode of the first signal and the number of sequences carried by the first signal. Taking the example of three modulation modes of the first signal and four sequences carried by the first signal, the first indication information may occupy four bits, the first two bits of which may indicate the modulation mode of the first signal, and the second two bits of which may indicate the number of sequences carried by the first signal. For example, when the bit value is 0111, it may indicate that the modulation mode of the first signal is the second modulation mode and the number of sequences carried by the first signal is four.

[0234] In a second possible embodiment, the first indication information may indicate the modulation mode of the first signal and whether the network device supports / allows activation of the second receiver of the terminal device. Taking three modulation modes of the first signal as an example, the first indication information may occupy three bits, the first two bits may indicate the modulation mode of the first signal, and the second bit may indicate whether the network device supports / allows activation of the second receiver of the terminal device. For example, when the bit value is 010, it may indicate that the modulation mode of the first signal is the second modulation mode and the network device does not support / allow activation of the second receiver of the terminal device.

[0235] In a third possible embodiment, the first indication information may indicate the number of sequences carried by the first signal and whether the network device supports / allows activation of the second receiver of the terminal device. Taking the number of sequences carried by the first signal as 4 as an example, the first indication information may occupy three bits, the first two bits may indicate the number of sequences carried by the first signal, and the last bit may indicate whether the network device supports / allows activation of the second receiver of the terminal device. For example, when the bit value is 110, it may indicate that the number of sequences carried by the first signal is 4 and the network device does not support / allow activation of the second receiver of the terminal device.

[0236] In a fourth possible embodiment, the first indication information may indicate the modulation mode of the first signal, the number of sequences carried by the first signal, and whether the network device supports / allows activation of the second receiver of the terminal device. Taking the case where there are three modulation modes of the first signal and the number of sequences carried by the first signal is 4 as an example, the first indication information may occupy five bits, the first two bits may indicate the modulation mode of the first signal, the last bit may indicate whether the network device supports / allows activation of the second receiver of the terminal device, and the remaining bits may indicate the number of sequences carried by the first signal. For example, when the bit value is 01110, it may indicate that the modulation mode of the first signal is the second modulation mode, the number of sequences carried by the first signal is 4, and the network device does not support / allow activation of the second receiver of the terminal device.

[0237] Optionally, the first indication information may be located in one or more of the following: system information block (SIB), master information block (MIB), broadcast message, RRC message, paging message, medium access control (MAC)-control element (CE), downlink control information (DCI) signaling, physical downlink control channel (PDCCH), physical downlink shared channel (PDSCH), channel status information reference signal (CSI-RS), demodulation reference signal (DMRS), tracking reference signal (TRS), paging message, short message; or, the first indication information may also be located in any new signal, channel, or signaling.

[0238] The SIB includes system information elements, and the SIB can group system information elements with the same properties together. Different SIBs can have different characteristics. The SIB can be located in the PDSCH.

[0239] Among them, the MIB is carried in the physical broadcast control channel (PBCH). For a certain cell, the MIB can contain reference information and scheduling information of multiple system information blocks of the cell. The MIB message carries the most basic information, which can be used for decoding the PDSCH channel (that is, the terminal device must decode the MIB first before it can use the information in the MIB to continue decoding the data in the PDSCH). In addition, the MIB information can include a cell barred field, which can indicate whether the terminal device is allowed to access the cell; the MIB information can also include a 1-bit spare field.

[0240] It can be understood that if the maximum number of SSBs in a synchronization signal and PBCH block (SSB) period is equal to 64, three bits are used in the PBCH field to indicate the index of the SSB; when the maximum number of SSBs in an SSB period is less than 64, only one bit is used in the PBCH field to indicate the index of the SSB, and two bits are reserved.

[0241] The PDCCH is used to carry DCI signaling and contains one or more control-channel elements (CCEs). The number of CCEs contained in the PDCCH is determined by the aggregation level. The aggregation level and the number of CCEs contained in the PDCCH can be shown in Table 1 below.

[0242] Table 1 Number of CCEs corresponding to aggregation levels

[0243] Optionally, the core network device may send the first indication information to the terminal device, that is, the first indication information may be located in a non-access stratum (NAS) message or other message.

[0244] Exemplarily, the NAS message may be one or more of the following: authentication request message, downlink (DL) NAS transport message, de-registration accept message, configuration update command message, protocol data unit (PDU), session establishment accept request, and PDU session authentication command.

[0245] S902: The terminal device determines whether to activate the second receiver according to the first indication information.

[0246] It is understandable that when the demodulation mode supported by the second receiver is the demodulation mode corresponding to the modulation mode of the first signal, the terminal device activates the second receiver; or when the demodulation mode supported by the second receiver is not the demodulation mode corresponding to the modulation mode of the first signal, the terminal device does not activate the second receiver. This application proposes three possible designs:

[0247] The first possible design is that when the first indication information indicates the modulation mode of the first signal, the terminal device can directly determine the modulation mode of the first signal, and can determine whether to activate the second receiver by determining whether the demodulation mode supported by the second receiver is the demodulation mode corresponding to the modulation mode of the first signal.

[0248] For example, taking the demodulation mode of the second receiver of the terminal device corresponding to the first modulation mode of the first signal as an example, assuming that there are three modulation modes, when the first indication information indicates the first modulation mode, the terminal device can determine to demodulate the first signal modulated based on the first modulation mode, and then determine to activate the second receiver; when the first indication information indicates the second modulation mode, the terminal device can determine that it cannot demodulate the first signal modulated based on the second modulation mode, and then determine not to activate the second receiver; when the first indication information indicates the third modulation mode, the terminal device can determine to demodulate the first signal modulated based on the third modulation mode, and then activate the second receiver.

[0249] The second possible design is that when the first indication information indicates the number of sequences carried by the first signal, the terminal device can determine the modulation method of the first signal based on the number of sequences carried by the first signal, and then determine whether to activate the second receiver by determining whether the demodulation method supported by the second receiver is the demodulation method corresponding to the modulation method of the first signal.

[0250] It can be understood that there is a correspondence between the number of sequences carried by the first signal and the modulation mode of the first signal. For example, the number of sequences carried by the first signal is 2, which can correspond to the first modulation mode, and the number of sequences carried by the first signal is 4, which can correspond to the second modulation mode.

[0251] For example, taking the case where the number of sequences carried by the first signal is 4 and the demodulation mode of the second receiver of the terminal device corresponds to the first modulation mode, the terminal device can determine that the modulation mode of the first signal is the second modulation mode based on the number of sequences carried by the first signal, while the modulation mode of the second receiver of the terminal device is the first modulation mode. At this time, the terminal device can determine not to activate the second receiver.

[0252] A third possible design is that when the first indication information indicates whether the network device allows / supports activation of the second receiver of the terminal device, the terminal device can directly determine whether to activate the second receiver, or the terminal device can determine whether the demodulation method corresponding to the modulation method of the first signal is the demodulation method of the second receiver, and then determine whether to activate the second receiver.

[0253] Exemplarily, when the first indication information indicates that the network device allows / supports activation of the second receiver of the terminal device, the terminal device can directly activate the second receiver, or the terminal device can determine that the demodulation method corresponding to the modulation method of the first signal is the demodulation method of the second receiver, and then determine to activate the second receiver; when the first indication information indicates that the network device does not allow / support activation of the second receiver of the terminal device, the terminal device can directly not activate the second receiver, or the terminal device can determine that the demodulation method corresponding to the modulation method of the first signal is not the demodulation method of the second receiver, and then determine not to activate the second receiver.

[0254] It is understandable that the terminal device can also determine whether to activate the second receiver through any two of the above possible designs or the above three possible designs. The specific determination method can refer to the above three possible designs and will not be repeated here.

[0255] It is understandable that after the terminal device activates the second receiver, the first signal can be received through the second receiver.

[0256] Furthermore, the terminal device may determine whether to activate the first receiver of the terminal device according to the first signal.

[0257] For example, taking the example of activating the first receiver of the terminal device by the first signal, when the terminal device receives the first signal through the first receiver, the sequence obtained after parsing the first signal can be compared with the preset sequence. When the sequence obtained after parsing the first signal is the same as the preset sequence, the first receiver of the terminal device can be activated; when the sequence obtained after parsing the first signal is different from the preset sequence, the first signal can be ignored.

[0258] It can be understood that the terminal device activates the first receiver according to the first signal, and can transmit data services and signaling with the network device through the first receiver, which can improve the reliability of communication; at the same time, it can ensure the effective activation of the first receiver, that is, it can avoid as much as possible the situation where the first receiver is activated but no data services and signaling are transmitted, which can effectively reduce the power consumption of the terminal device.

[0259] Optionally, the terminal device may also monitor paging messages, broadcast messages, etc. through the second receiver.

[0260] It is understandable that the terminal device continuously monitors the paging message (or broadcast message) through the second receiver, and can respond to the paging message (or broadcast message) from the network device in a timely manner, thereby improving the reliability of communication.

[0261] Based on the communication method shown in Figure 9, the first indication information can indicate the modulation mode of the first signal, and the terminal device can determine whether to activate the second receiver by determining whether the demodulation mode of the second receiver is the demodulation mode corresponding to the modulation mode of the first signal; or, the first indication information can indicate the number of sequences superimposed on the first signal, and the terminal device can determine the modulation mode of the first signal based on the number of sequences superimposed on the first signal, and can determine whether to activate the second receiver by determining whether the demodulation mode of the second receiver is the demodulation mode corresponding to the modulation mode of the first signal; or, the first indication information can directly indicate the terminal device whether to activate the second receiver.

[0262] Among them, the terminal device can determine whether the second receiver of the terminal device can successfully parse the first signal based on the first indication information, and then determine whether to activate the second receiver. In this way, when the terminal device activates the second receiver, it can avoid as much as possible the situation where the terminal device cannot parse the first signal but attempts to receive the first signal, which can effectively reduce the power consumption of the terminal device; or, in this way, when the terminal device determines that it cannot parse the first signal, it can directly put the second receiver into a dormant state, which can effectively reduce the power consumption of the terminal device. For example, the network device may expect to modulate the first signal only according to a certain modulation method, or only support modulation of the first signal according to a certain modulation method. The first signal modulated according to the modulation method is only applicable to the second receiver of some types of terminal devices. In this way, the terminal device can know whether the first signal is applicable to its own second receiver through the first indication information, and thus determine whether to activate the second receiver to detect the first signal.

[0263] Based on the first indication information shown in S901, optionally, the first indication information may indicate one or more of the following: the network device allows activation of the second receiver of the terminal device, the network device does not allow activation of the second receiver of the terminal device, the network device supports activation of the second receiver of the terminal device, the network device does not support activation of the second receiver of the terminal device, the type of terminal device that the network device allows activation of the second receiver, the type of terminal device that the network device does not allow activation of the second receiver, the type of terminal device that the network device supports activation of the second receiver, the type of terminal device that the network device does not support activation of the second receiver, the time period in which the network device allows activation of the second receiver of the terminal device, the time period in which the network device does not allow activation of the second receiver of the terminal device, the time period in which the network device supports activation of the second receiver of the terminal device, the time period in which the network device does not support activation of the second receiver of the terminal device, the working frequency supported by the network device, the maximum number of working frequencies supported by the terminal device supported by the network device, resources supported by the network device for sending the first signal, the terminal device that the network device allows supporting the working frequency to receive the first signal, the working frequency supported by the network device is less than the first preset frequency, and the working frequency supported by the network device is greater than the second preset frequency.

[0264] Among them, this application proposes several possible designs:

[0265] In a first possible design, the first indication information is used to indicate one or more of the following: the network device allows activation of the second receiver of the terminal device, the network device does not allow activation of the second receiver of the terminal device, the network device supports activation of the second receiver of the terminal device, and the network device does not support activation of the second receiver of the terminal device. The terminal device can directly determine whether to activate the second receiver based on the first indication information.

[0266] Among them, the first indication information in the first possible design can refer to the description of the first indication information in the above S901, which will not be repeated here.

[0267] In a second possible design, the first indication information is used to indicate one or more of the following: the type of terminal device that the network device allows to activate the second receiver, the type of terminal device that the network device does not allow to activate the second receiver, the type of terminal device that the network device supports to activate the second receiver, and the type of terminal device that the network device does not support to activate the second receiver. The terminal device can determine whether to activate the second receiver by determining whether the type of terminal device indicated by the first indication information is consistent with its own type.

[0268] Among them, the second receivers of different types of terminal devices support different demodulation modes.

[0269] Among them, the different demodulation modes supported by the second receivers of different types of terminal devices can be understood as the different demodulation capabilities supported by the second receivers of different types of terminal devices, or, it can be understood as the different architectures of the second receivers of different types of terminal devices, or, it can be understood as the different power consumption of the second receivers of different types of terminal devices, or, it can be understood as the different demodulation complexity of the second receivers of different types of terminal devices, or, it can be understood as the different detection (or demodulation) accuracy of the second receivers of different types of terminal devices, or, it can be understood as the different coverage performance supported by the second receivers of different types of terminal devices, or, it can also be understood as the different anti-interference performance of the second receivers of different types of terminal devices.

[0270] Exemplarily, the terminal device can be divided into a first terminal device, a second terminal device, and a third terminal device based on the three existing modulation modes of the first signal. The first terminal device can demodulate the first signal modulated based on the first modulation mode and the third modulation mode, the second terminal device can demodulate the first signal modulated based on the second modulation mode and the third modulation mode, and the third terminal device can demodulate the first signal modulated based on any of the above modulation modes.

[0271] Based on the second possible design, the present application proposes a possible embodiment. Taking the existence of three types of terminal devices as an example, the first indication information can be a bit map (each bit in the bit map corresponds to the type of terminal device), and the bit map is three bits. When the bit map is 100, it can indicate that the network device allows / supports activation of the second receiver of the first type of terminal device; when the bit map is 010, it can indicate that the network device allows / supports activation of the second receiver of the second type of terminal device; when the bit map is 001, it can indicate that the network device allows / supports activation of the second receiver of the third type of terminal device; when the bit map is 101, it can indicate that the network device allows / supports activation of the second receiver of the first type of terminal device and the third type of terminal device; when the bit map is 010, it can indicate that the network device allows / supports activation of the second receiver of the second type of terminal device and the third type of terminal device.

[0272] Alternatively, the first indication information may indicate the index of the type of terminal device. The first indication information may indicate the index of the type of a terminal device through two bits. When the bit value is 00, it may indicate that the network device allows / supports activation of the second receiver of the first category terminal device; when the bit value is 01, it may indicate that the network device allows / supports activation of the second receiver of the second category terminal device; when the bit value is 10, it may indicate that the network device allows / supports activation of the second receiver of the third category terminal device; when the bit value is 0010, it may indicate that the network device allows / supports activation of the second receiver of the first category terminal device and the third category terminal device; when the bit value is 0110, it may indicate that the network device allows / supports activation of the second receiver of the second category terminal device and the third category terminal device.

[0273] Based on the above description of the types of terminal devices, optionally, different types of terminal devices may have different demodulation modes and the first parameters corresponding to the different types of terminal devices may also be different.

[0274] Among them, the first parameter is one or more of the following: the maximum number of bits of the first signal supported by the terminal device, the number of sequences supported for demodulation by the terminal device, resource information supported by the terminal device for receiving the first signal, the operating frequency supported by the terminal device, the type of synchronization signal supported by the terminal device for receiving, the operating time period supported by the terminal device, the transmission bandwidth supported by the terminal device, the maximum baseband bandwidth supported by the terminal device, the maximum radio frequency bandwidth supported by the terminal device, and the maximum data rate supported by the terminal device.

[0275] In the first example, regarding the number of sequences supported for demodulation by the terminal device, taking two types of terminal devices (such as a first terminal device and a second terminal device) as an example, the number of sequences supported for demodulation by the first terminal device can be 2, and the number of sequences supported for demodulation by the second terminal device can be 4.

[0276] In the second example, for the resource information that the terminal device supports receiving the first signal, the terminal device can support receiving the first signal on different time domain resources, frequency domain resources, code domain resources, or time-frequency domain resources.

[0277] In the third example, for the operating frequencies supported by the terminal device, taking two types of terminal devices (such as a first terminal device and a second terminal device) as an example, the operating frequency of the first terminal device can be 800MHz and 1900MHz, and the operating frequency of the second terminal device can be 2.6GHz; or, the operating frequency of the first terminal device is high frequency and low frequency, and the operating frequency of the second terminal device is only low frequency; or, the operating frequency of the first terminal device is high frequency, and the operating frequency of the second terminal device is low frequency.

[0278] The high and low frequencies may be limited by defining frequencies above a preset threshold as high frequency and frequencies below a preset threshold as low frequency, or by defining frequencies through a communication protocol without any restriction.

[0279] In the fourth example, for the working time periods supported by the terminal device, taking the existence of two types of terminal devices (such as a first terminal device and a second terminal device) as an example, the first terminal device can support working in the first time period, and the second terminal device can support working in the second time period.

[0280] Among them, the first time period and the second time period can be continuous (such as the end time of the first time period is the start time of the second time period), or there is a time interval between the first time period and the second time period, or the first time period and the second time period can alternate in a time division multiplexing manner (that is, the working time of the first terminal device and the second terminal device is periodic. For example, taking six cycles as an example, the first cycle, the third cycle, and the fifth cycle can be understood as the first time period; the second cycle, the fourth cycle, and the sixth cycle can be understood as the second time period).

[0281] Optionally, the first parameter can also be one or more of the following: the number of resources supported or configured by the terminal device, the number of transmitting antenna ports, the number of receiving antenna ports, the number of transmitting antenna ports and the number of receiving antenna ports, the number of RF channels, the number of hybrid automatic repeat request (HARQ) processes, the supported peak rate, application scenarios, latency requirements, and the ability to process data or signaling.

[0282] Exemplarily, the number of resources supported or configured for the terminal device may be one or more of the following: the number of resource blocks (RBs), the number of resource elements (REs), the number of subcarriers, the number of RB groups, the number of RE group (REG) bundles (REG bundle is a new concept introduced by NR), the number of control channel elements, the number of subframes, the number of radio frames, the number of time slots, the number of mini time slots, and the number of symbols.

[0283] Among them, REG is the basic unit of PDCCH resource mapping, one REG is defined as one RB on one OFDM symbol, and one RB is defined as 12 consecutive subcarriers in frequency and one OFDM symbol in time domain.

[0284] The REGs may be first formed into a REG bundle in a time-first (TF) mapping manner, and then mapped to the control resource in an interleaved or non-interleaved manner with the REG bundle as the granularity.

[0285] It can be understood that one REG bundle consists of a group of continuous REGs in the time domain and / or frequency domain, and the size of one REG bundle is equal to the size of the REG in the frequency domain multiplied by the size of the OFDM symbol in the time domain.

[0286] Based on the above description of the first parameter, the type of terminal device can be distinguished based on one or more of the above parameters, so that the network device can determine the capability of the terminal device according to the above parameters, and then determine whether the second receiver of the terminal device is activated according to the capability of the terminal device.

[0287] It can be understood that when there are multiple types of terminal devices in a communication system or cell, the network device can indicate which type of terminal device is allowed / supported to activate the second receiver by sending at least one first indication information, so as to ensure as much as possible that the terminal device that activates the second receiver can successfully parse the first signal, thereby improving the reliability of communication.

[0288] Based on the second possible design, the network device can send a first message to instruct multiple terminal devices to determine whether to activate the second receiver, which can effectively reduce the transmission overhead. At the same time, it can effectively reduce the load of the network device and improve the working efficiency of the network device.

[0289] In a third possible design, the first indication information indicates one or more of the following: a time period in which the network device allows activation of the second receiver of the terminal device, a time period in which the network device does not allow activation of the second receiver of the terminal device, a time period in which the network device supports activation of the second receiver of the terminal device, and a time period in which the network device does not support activation of the second receiver of the terminal device. The terminal device can determine the time period for activating the second receiver.

[0290] The above time period can be described as a time range, or can be described as a duration.

[0291] Exemplarily, the time period may include one or more time units, and the time unit may be one or more of the following: hour (h), minute (min), s, ms, time slot, frame, and subframe.

[0292] Based on the third possible design, the present application proposes a possible embodiment. Taking the existence of two time periods (such as the first time period and the second time period) as an example, the first indication information can be a bit map. When the bit map is 00, it can indicate that the network device does not allow / support activation of the second receiver of the terminal device; when the bit map is 10, it can indicate that the time period for which the network device allows / supports activation of the second receiver of the terminal device is the first time period; when the bit map is 01, it can indicate that the time period for which the network device allows / supports activation of the second receiver of the terminal device is the second time period; when the bit map is 11, it can indicate that the time period for which the network device allows / supports activation of the second receiver of the terminal device is the first time period and the second time period.

[0293] Based on the third possible design, it is possible to ensure that the terminal device successfully parses the received first signal during the time period when the second receiver is activated, and it is also possible to ensure that the network device does not send the first signal to the terminal device during the time period when the second receiver is not activated, thereby improving the efficiency of information exchange between the terminal device and the network device. In addition, the network device can dynamically instruct the terminal device to activate the second receiver time period based on the actual communication scenario or communication situation. By configuring different time periods, different types of terminal devices can activate the second receiver in different time periods, which can meet the needs of network device load balancing and improve the flexibility of determining time periods.

[0294] In a fourth possible design, the first indication information indicates one or more of the following: an operating frequency supported by the network device, the maximum number of operating frequencies supported by terminal devices supported by the network device, resources supported by the network device for sending the first signal, terminal devices supporting the operating frequency allowed by the network device to receive the first signal, an operating frequency supported by the network device less than the first preset frequency, and an operating frequency supported by the network device greater than the second preset frequency. The terminal device can determine whether to activate the second receiver based on whether the operating frequency of the terminal device is consistent with the operating frequency of the network device (can also be described as the same).

[0295] Among them, for the operating frequency points supported by the network device, this application proposes two possible embodiments:

[0296] In one possible embodiment, taking the first indication information as one bit as an example, when the bit value is 1, it may indicate that the operating frequency supported by the network device is less than the first preset frequency; when the bit value is 0, it may indicate that the operating frequency supported by the network device is greater than the second preset frequency. Alternatively, when the bit value is 0, it may indicate that the operating frequency supported by the network device is less than the first preset frequency; when the bit value is 1, it may indicate that the operating frequency supported by the network device is greater than the second preset frequency.

[0297] In another possible embodiment, taking the first indication information indicating the index of the operating frequency as an example, assuming that there are four operating frequencies (such as the index of the first operating frequency is 0, the index of the second operating frequency is 1, the index of the third operating frequency is 2, and the index of the fourth operating frequency is 3), then the first indication information may represent the index of one operating frequency by two bits. When the bit value is 00, it can be indicated that the index of the operating frequency is 0, that is, the network device supports the first operating frequency; when the bit value is 01, it can be indicated that the index of the operating frequency is 1, that is, the network device supports the second operating frequency; When the bit value is 10, it can indicate that the index of the working frequency is 2, that is, the network device supports the third working frequency; when the bit value is 11, it can indicate that the index of the working frequency is 3, that is, the network device supports the fourth working frequency; when the bit value is 0001, it can indicate that the index of the working frequency is 0 and 1, that is, the network device supports the first working frequency and the second working frequency; when the bit value is 00011011, it can indicate that the index of the working frequency is 0, 1, 2, and 3, and the network device supports the first working frequency, the second working frequency, the third working frequency, and the fourth working frequency.

[0298] Alternatively, taking the first indication information as a bit map (each bit in the bit map indicates a working frequency) as an example, assuming that there are four working frequencies (such as the first working frequency, the second working frequency, the third working frequency, and the fourth working frequency), when the bit map is 1000, it can indicate that the network device supports the first working frequency; when the bit map is 0100, it can indicate that the network device supports the second working frequency; when the bit map is 0010, it can indicate that the network device supports the third working frequency; when the bit map is 0001, it can indicate that the network device supports the fourth working frequency; when the bit map is 1100, it can indicate that the network device supports the first working frequency and the second working frequency; when the bit map is 1111, it can indicate that the network device supports the first working frequency, the second working frequency, the third working frequency, and the fourth working frequency.

[0299] Among them, for the resources supported by the network device for sending the first signal, the first indication information can indicate time domain resources, frequency domain resources, code domain resources, time-frequency domain resources, etc. The specific indication method can refer to the description of the second indication information and will not be repeated here.

[0300] Among them, for the maximum number of working frequencies supported by the terminal device supported by the network device, the terminal device can determine whether to activate the second receiver based on the number of supported working frequencies. For example, when the number of working frequencies supported by the terminal device is greater than the maximum number of working frequencies supported by the terminal device supported by the network device, the terminal device does not activate the second receiver; when the number of working frequencies supported by the terminal device is less than or equal to the maximum number of working frequencies supported by the terminal device supported by the network device, the terminal device can activate the second receiver.

[0301] Based on the above four possible designs, this application proposes several possible embodiments:

[0302] In a first possible embodiment, the first indication information may indicate whether the network device allows / supports activation of the second receiver of the terminal device and the time period. Taking the existence of two time periods as an example, the first indication information may occupy two bits, the first bit may indicate whether the network device allows / supports activation of the second receiver of the terminal device, and the second bit may indicate the time period. When the bit value is 00, it may indicate that the network device does not allow / support activation of the second receiver of the terminal device in the first time period; when the bit value is 01, it may indicate that the network device does not allow / support activation of the second receiver of the terminal device in the second time period; when the bit value is 10, it may indicate that the network device allows / supports activation of the second receiver of the terminal device in the first time period; when the bit value is 11, it may indicate that the network device allows / supports activation of the second receiver of the terminal device in the second time period.

[0303] In a second possible embodiment, the first indication information may indicate whether the network device allows / supports activation of the second receiver of the terminal device and the type of the terminal device. Taking the case where there are three types of terminal devices as an example, the first indication information may occupy three bits, the first bit may indicate whether the network device allows / supports activation of the second receiver of the terminal device, and the remaining bits may indicate the type of the terminal device. When the bit value is 000, it may indicate that the network device does not allow / support activation of the second receiver of the first terminal device; when the bit value is 001, it may indicate that the network device does not allow / support activation of the second receiver of the second terminal device; when the bit value is 010, it may indicate that the network device does not allow / support activation of the second receiver of the third terminal device; when the bit value is 100, it may indicate that the network device allows / supports activation of the second receiver of the first terminal device; when the bit value is 101, it may indicate that the network device allows / supports activation of the second receiver of the second terminal device; and when the bit value is 110, it may indicate that the network device allows / supports activation of the second receiver of the third terminal device.

[0304] In a third possible embodiment, the first indication information may indicate whether the network device allows / supports activation of the second receiver of the terminal device, the time period, and the type of the terminal device. Taking three types of terminal devices and two time periods as an example, the first indication information may occupy four bits, the first bit may indicate whether the network device allows / supports activation of the second receiver of the terminal device, the second bit may indicate the type of the terminal device, and the remaining bits may indicate the time period. When the bit value is 0000, it may indicate that the network device does not allow / support activation of the second receiver of the first terminal device in the first time period; when the bit value is 1000, it may indicate that the network device allows / supports activation of the second receiver of the first terminal device in the first time period; when the bit value is 1001, it may indicate that the network device allows / supports activation of the second receiver of the first terminal device in the second time period; when the bit value is 1011, it may indicate that the network device allows / supports activation of the second receiver of the second terminal device in the second time period; when the bit value is 1101, it may indicate that the network device allows / supports activation of the second receiver of the third terminal device in the second time period.

[0305] Optionally, the first indication information may further indicate the number of repetitions of sending the first signal within a time range.

[0306] A time range may be a paging cycle, or a connected discontinuous reception (CDRX) cycle, or a first signal monitoring cycle.

[0307] It is understandable that when the demodulation method of the second reception of the terminal device is different, it will lead to different coverage performance. For example, when the second receiver is a second receiver for envelope detection, the coverage is poor, and in order to improve the coverage performance, it is necessary to repeatedly send the first signal; and when the second receiver is a second receiver for OFDM detection, correlation detection, or sequence detection, the coverage performance is better, and it is not necessary to repeatedly send the first signal or to repeat the first signal a fewer number of times.

[0308] It is understandable that the terminal device can determine whether the second receiver can successfully parse the first signal based on the number of repetitions of the first signal, and further determine whether to activate the second receiver.

[0309] For example, taking the first indication information occupying three bits as an example, when the bit value is 000, it may indicate that the number of repetitions of sending the first signal within a time range is 1; when the bit value is 001, it may indicate that the number of repetitions of sending the first signal within a time range is 2; when the bit value is 010, it may indicate that the number of repetitions of sending the first signal within a time range is 3;…; when the bit value is 111, it may indicate that the number of repetitions of sending the first signal within a time range is 8.

[0310] Based on the communication method shown in Figure 9, optionally, when the terminal device receives the first indication information from the network device, the network device can configure the first indication information; or, the network device can receive the first indication information from the network device; or, the network device can receive the first information from the core network device and determine the first indication information based on the first information.

[0311] The first information is used to indicate a modulation method of the first signal.

[0312] Furthermore, the network device may send first indication information to the terminal device.

[0313] Optionally, the network device may determine the modulation method of the first signal, or the core network device may indicate the modulation method of the first signal, without limitation.

[0314] Optionally, the terminal device may obtain second indication information and may determine resources for receiving the first signal based on the second indication information.

[0315] The second indication information is used to indicate the resources for the terminal device to receive the first signal; or, the second indication information is used to indicate the resources for the terminal device to receive the first signal through the second receiver.

[0316] Exemplarily, the resources used by the terminal device to receive the first signal may be one or more of the following: a control resource set (CORESET), a random access resource, and a synchronization information resource.

[0317] The control resource set is used to represent a set of time-frequency resources that carry a PDCCH. A control resource set may be composed of a number of RBs in the frequency domain and a number of symbols in the time domain.

[0318] It is understandable that a terminal device may correspond to multiple control resource sets, and each control resource set can only be bound to one CCE to REG mapping relationship.

[0319] Optionally, the second indication information may include one or more of the following: time domain resource information, frequency domain resource information, time-frequency domain resource information, code domain resource information, time domain resource offset information, frequency domain resource offset information, and code domain resource offset information.

[0320] It can be understood that the second indication information may indicate a resource, a range of a resource, or offset information of a resource.

[0321] In a possible embodiment, the second indication may indicate time domain resource information.

[0322] In one example, the time domain resource information may be an index of a time domain resource. Taking the existence of four time domain resources (such as the index of the first time domain resource is 0, the index of the second time domain resource is 1, the index of the third time domain resource is 2, and the index of the fourth time domain resource is 3) as an example, the time domain resource information may represent one time domain resource in two bits. When the bit value is 00, it may represent that the index of the time domain resource is 0, then the terminal device may receive the first signal on the first time domain resource; when the bit value is 01, it may represent that the index of the time domain resource is 1, then the terminal device may receive the first signal on the second time domain resource; when the bit value is 10, it may represent that the time domain resource is When the index of the resource is 2, the terminal device can receive the first signal on the third time domain resource; when the bit value is 11, it can indicate that the index of the time domain resource is 3, then the terminal device can receive the first signal on the fourth time domain resource; when the bit value is 0011, it can indicate that the index of the time domain resource is 0 and 3, then the terminal device can receive the first signal on the first time domain resource and the fourth time domain resource; when the bit value is 00011011, it can indicate that the index of the time domain resource is 0, 1, 2, and 3, then the terminal device can receive the first signal on the first time domain resource, the second time-frequency resource, the third time-frequency resource, and the fourth time domain resource.

[0323] In another example, the time domain resource information may be a bit map (each bit in the bit map corresponds to a time domain resource). Taking four time domain resources (such as the first time domain resource, the second time domain resource, the third time domain resource, and the fourth time domain resource) as an example, when the bit map is 1000, the terminal device can receive the first signal on the first time domain resource; when the bit map is 0100, the terminal device can receive the first signal on the second time domain resource; when the bit map is 0010, the terminal device can receive the first signal on the third time domain resource; when the bit map is 0001, the terminal device can receive the first signal on the fourth time domain resource; when the bit map is 1001, the terminal device can receive the first signal on the first time domain resource and the fourth time domain resource; when the bit map is 1111, the terminal device can receive the first signal on the first time domain resource, the second time-frequency resource, the third time-frequency resource, and the fourth time domain resource.

[0324] The above embodiments can also be applied to frequency domain resource information, code domain resource information, and time-frequency domain resource information, which will not be described in detail here.

[0325] In another possible embodiment, the second indication information may indicate time domain resource offset information, and the starting position of the time-frequency resource may be predefined, or may be indicated by the second indication information (the indication method may refer to the description of the above-mentioned second indication information indicating the time domain resource information, such as a time point or timestamp may be indicated by the time domain resource information), or may be indicated by other information.

[0326] Exemplarily, the time domain resource offset information may indicate the index of the offset. Taking the existence of four offsets (such as the first offset, the second offset, the third offset, and the fourth offset) as an example, the time domain resource offset information may occupy two bits. When the bit value is 00, it may indicate that the index of the offset is 0, that is, the terminal device can determine the time domain resource based on the first offset and receive the first signal on the time domain resource; when the bit value is 01, it may indicate that the index of the offset is 1, that is, the terminal device can determine the time domain resource based on the second offset and receive the first signal on the time domain resource; when the bit value is 10, it may indicate that the index of the offset is 2, that is, the terminal device can determine the time domain resource based on the third offset and receive the first signal on the time domain resource; when the bit value is 11, it may indicate that the index of the offset is 3, that is, the terminal device can determine the time domain resource based on the first offset and receive the first signal on the time domain resource.

[0327] Among them, the above embodiments can also be used for frequency domain resource offset information, frequency domain resource offset information, and code domain resource offset information, which will not be described in detail here.

[0328] It can be understood that the second indication information can jointly indicate resource information and resource offset information based on the above two possible embodiments. The specific indication method can refer to the above two possible embodiments and will not be described in detail here.

[0329] It is understandable that the resources used by different types of terminal devices to receive the first signal may be time division multiplexed, frequency division multiplexed, or code division multiplexed, without limitation.

[0330] It is understandable that different types of terminal devices use different resources to receive the first signal.

[0331] For example, taking the example of a first terminal device receiving a first signal on a first resource and a second terminal device receiving a first signal on a second resource, the first resource and the second resource may be independent of each other, or the resource unit in the first resource and the resource unit in the second resource may be independent of each other.

[0332] For example, the first resource and the second resource may be in a multiple relationship. For example, when the first resource is a first duration and the second resource is a second duration, the first duration may be m times the second duration.

[0333] Wherein, m is a positive integer.

[0334] It can be understood that the terminal device can receive the second indication information from the network device, or the terminal device can receive the second indication information from the core network device.

[0335] For example, when the terminal device receives the second indication information from the network device, the second indication information may be located in one or more of the following: SIB, MIB, broadcast message, RRC message, paging message, MAC-CE, DCI signaling, PDCCH, PDSCH, CSI-RS, DMRS, TRS, paging message, short message; or, the second indication information may also be located in any new signal, channel, or signaling. When the terminal device receives the second indication information from the core network device, the second indication information may be located in a NAS message or other message.

[0336] It can be understood that the second indication information can be located in the first indication information, or the second indication information can be located in the same message as the first indication information, or the second indication information can be transmitted separately, without limitation.

[0337] Based on the above description of the second indication information, the terminal device can receive the first signal on the resource indicated by the second indication information, which can avoid interference between the received first signal and other signals (first signals received by other terminal devices) as much as possible, and can improve the reliability of communication; in addition, the network device can dynamically instruct the terminal device to receive the resource of the first signal according to the actual communication scenario or communication situation, which can avoid the situation where multiple terminal devices receive the first signal on the same resource, causing resource congestion, as much as possible, which is conducive to meeting the load balancing requirements of the network device and can improve the flexibility of determining resources.

[0338] Based on the above description of the second indication information, the second indication information can be transmitted jointly with the first indication information, for example, the first indication information and the second indication information can occupy at least three bits, the first bit can indicate whether the network device allows / supports activation of the second receiver of the terminal device, the second bit can indicate whether the network device allows / supports activation of the second receiver of a certain type of terminal device, and the remaining bits can indicate the resources of the terminal device for receiving the first signal.

[0339] Optionally, the terminal device can obtain third indication information and can determine the beam information associated with receiving the first signal based on the third indication information.

[0340] The third indication information is used to instruct the terminal device to receive beam information associated with the first signal; or, the third indication information is used to instruct the terminal device to receive beam information associated with the first signal through the second receiver; or, the third indication information is used to instruct the network device to send beam information associated with the first signal.

[0341] Among them, beam information can be understood as the number of synchronization signals sent by the network device within a time range, or it can be understood as the number of synchronization signals received by the terminal device within a time range, or it can be understood as the index of the synchronization signal sent by the network device within a time range, or it can be understood as the index of the synchronization signal received by the terminal device within a time range, or it can be understood as the number of first signals sent by the network device within a time range, or it can be understood as the number of first signals received by the terminal device within a time range, or it can be understood as the index of the first signal sent by the network device within a time range, or it can be understood as the index of the first signal received by the terminal device within a time range.

[0342] A time range may be a paging cycle, or a CDRX cycle, or a first signal monitoring cycle.

[0343] It can be understood that the multiple synchronization signals or the multiple first signals sent by the network device are not identical repeatedly sent signals.

[0344] In a first possible embodiment, the third indication information may indicate the number of first signals sent by the network device within a time range. Assuming that the third indication information occupies two bits, when the bit value is 00, it may indicate that the number of first signals sent by the network device within a time range is 1, that is, the terminal device receives one first signal within a time range; when the bit value is 01, it may indicate that the number of first signals sent by the network device within a time range is 2, that is, the terminal device receives two different first signals within a time range; when the bit value is 10, it may indicate that the number of first signals sent by the network device within a time range is 3, that is, the terminal device receives three different first signals within a time range; when the bit value is 11, it may indicate that the number of first signals sent by the network device within a time range is 4, that is, the terminal device receives four different first signals within a time range.

[0345] In a second possible embodiment, the third indication information may indicate the index of the first signal sent by the network device within a time range. Assuming that there are four first signals (such as the index of the first signal 0 is 0, the index of the first signal 1 is 1, the index of the first signal 2 is 2, and the index of the first signal 3 is 3), the third indication information may indicate a first signal through two bits. When the bit value is 00, it may indicate that the index of the first signal is 0, that is, the network device can send the first signal 0 within a time range, and the terminal device can receive the first signal 0 within a time range; when the bit value is 01, it may indicate that the index of the first signal is 1, that is, the network device can send the first signal 1 within a time range, and the terminal device can receive the first signal 1 within a time range; when the bit value is 10, it may indicate that the index of the first signal is 2, that is, the network device can send the first signal 2 within a time range, and the terminal device can receive the first signal 2 within a time range. The first signal 2 is received; when the bit value is 11, it can indicate that the index of the first signal is 3, that is, the network device can send the first signal 3 within a time range, and the terminal device can receive the first signal 3 within a time range; when the bit value is 0001, it can indicate that the index of the first signal is 0 and 1, that is, the network device can send the first signal 0 and the first signal 1 within a time range, and the terminal device can receive the first signal 0 and the first signal 1 within a time range; when the bit value is 00011011, it can indicate that the index of the first signal is 0, 1, 2, and 3, that is, the network device can send the first signal 0, the first signal 1, the first signal 2, and the first signal 4 within a time range, and the terminal device can receive the first signal 0, the first signal 1, the first signal 2, and the first signal 4 within a time range.

[0346] It can be understood that the terminal device can receive the third indication information from the network device, or the terminal device can receive the third indication information from the core network device.

[0347] For example, when the terminal device receives the third indication information from the network device, the third indication information may be located in one or more of the following: SIB, MIB, broadcast message, RRC message, paging message, MAC-CE, DCI signaling, PDCCH, PDSCH, CSI-RS, DMRS, TRS, paging message, short message; or the third indication information may also be located in any new signal, channel, or signaling. When the terminal device receives the third indication information from the core network device, the third indication information may be located in a NAS message or other message.

[0348] It can be understood that the third indication information can be located in the first indication information, or the third indication information can be located in the same message as the first indication information, or the third indication information can be transmitted separately, without limitation.

[0349] Based on the description of the third indication information, the terminal device can receive the first signal based on one or more beams indicated by the third indication information. In addition, the network device can dynamically instruct the terminal device to receive the beam associated with the first signal according to the actual communication scenario or communication situation, which can improve the flexibility of determining the beam associated with the first signal.

[0350] Based on the description of the third indication information, the third indication information can be transmitted jointly with the first indication information, for example, the first indication information and the second indication information can occupy at least three bits, the first bit can indicate whether the network device allows / or supports activating the second receiver of the terminal device, the second bit can indicate whether the network device allows / or supports activating the second receiver of a certain type of terminal device, and the remaining bits can indicate that the terminal device receives beam information associated with the first signal.

[0351] It is understandable that the first indication information can be transmitted jointly with the second indication information and the third indication information, for example, the second indication information and the third indication information can be located in the first indication information, or the first indication information, the second indication information, and the third indication information can be located in the same message. For example, the first indication information, the second indication information, and the third indication information can occupy at least four bits, the first bit can indicate whether the network device allows / or supports activation of the second receiver of the terminal device, the second bit can indicate whether the network device allows / or supports activation of the second receiver of a certain type of terminal device, and the remaining bits can indicate the resources for the terminal device to receive the first signal and the beam information associated with the terminal device receiving the first signal.

[0352] It can be understood that the network device can send one or more indication information (i.e., first indication information, second indication information, and third indication information). For example, when the terminal device is in the RRC inactive state and the RRC idle state, the network device can send one indication information to multiple terminal devices; when the terminal device is in the RRC connected state, the network device can send different indication information to different terminal devices.

[0353] Optionally, the terminal device may also obtain perception information.

[0354] It is understandable that the terminal device can also obtain the time period (or time range), resources, etc. associated with the perception information.

[0355] Optionally, the present application also proposes a communication method, in which the terminal device can actively request the network device to send a first signal. The terminal device can send request information to the network device (as shown in Figure 10) or send request information to the core network device (as shown in Figure 11).

[0356] The specific steps of the communication method shown in FIG10 may be as follows:

[0357] S1001. The terminal device sends a first request message to the network device.

[0358] The first request information is used to request receiving a first signal.

[0359] Exemplarily, the first request information may be located in one or more of the following: message 1 (message 1, Msg 1), message 3 (message 3, Msg 3), uplink control information (uplink control information, UCI), and HARQ message.

[0360] Optionally, the network device may directly send a first signal to the terminal device based on the first request information (as shown in S1002), or the network device may send a first indication information to the terminal device to enable the terminal device to determine whether the network device allows / supports activation of the second receiver of the terminal device (as shown in S1004-S1006), or the network device may send a response information based on the first request information to enable the terminal device to determine whether the network device agrees to send the first signal (as shown in S1007-S1009).

[0361] S1002. The network device sends a first signal to the terminal device according to the first request information; correspondingly, the terminal device receives the first signal through the second receiver.

[0362] The first signal may refer to the description of the first signal in S901 above, which will not be repeated here.

[0363] S1003. The network device sends first indication information to the terminal device according to the first request information; correspondingly, the terminal device receives the first indication information from the network device.

[0364] Among them, S1003 can refer to S901 and will not be described in detail here.

[0365] S1004. The terminal device determines whether to activate the second receiver according to the first indication information.

[0366] Among them, S1004 can refer to S902 and will not be described in detail here.

[0367] Furthermore, when the network device allows / supports activation of the second receiver of the terminal device, the terminal device can receive the first signal from the network device through the second receiver (as shown in S1005). Alternatively, when the network device does not allow / support activation of the second receiver of the terminal device, the second receiver of the terminal device is in a dormant state (as shown in S1006) and does not receive the first signal.

[0368] S1007. The network device sends first response information to the terminal device according to the first request information. Correspondingly, the terminal device receives the first response information from the network device.

[0369] The first response information is used to respond to the first request information.

[0370] Optionally, the first response information can also be used to indicate one or more of the following: whether the network device supports the terminal device to activate the second receiver, whether the network device allows the terminal device to activate the second receiver, and the resources for the terminal device to receive the first signal.

[0371] It is understood that when the first response information indicates that the network device allows / supports activation of the second receiver of the terminal device, the terminal device can receive the first signal through the second receiver (as shown in S1008). Alternatively, when the first response information indicates that the network device does not allow / support activation of the second receiver of the terminal device, the second receiver of the terminal device is in a dormant state and does not receive the first signal (as shown in S1009).

[0372] It can be understood that when the first response information indicates the resource for the terminal device to receive the first signal, the terminal device can determine that the network device allows / supports activating the second receiver of the terminal device, and further, the terminal device can receive the first signal through the second receiver on the resource.

[0373] For the resources, please refer to the above description of resources and will not be elaborated here.

[0374] Based on the communication method shown in FIG10 , the terminal device can send a first request message to the network device to actively request the network device to send a first signal. This can effectively solve the situation where the terminal device needs to receive the first signal but the network device does not allow / support activation of the second receiver of the terminal device, thereby improving communication performance. For example, the network device may expect to modulate the first signal only according to a certain modulation method, but also supports modulation of the first signal according to other modulation methods. In this way, even if the second receiver of the terminal device is not compatible with the first signal modulated according to the modulation method expected by the network device, the terminal device can request the network device to send the first signal suitable for its own second receiver.

[0375] The specific steps of the communication method shown in FIG11 may be as follows:

[0376] S1101. The terminal device sends a first request message to the core network device.

[0377] The first request information may refer to the description of the first request information in S1001.

[0378] In one example, when the terminal device is in an RRC idle state or an inactive state, the first request information may be located in one or more of the following: a registration request message, a service request message, or a de-registration request message.

[0379] In another example, when the terminal device is in the RRC connected state, the first request information may be located in one or more of the following: configuration update request message, uplink (UL) NAS transmission message, authentication response message, authentication result message, registration accept message, PDU session establishment request message, physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH), sounding reference signal (SRS), and HARQ message.

[0380] Optionally, the core network device can forward the first request information to the network device (as shown in S1102). Further, the network device can execute the steps shown in Figure 10, or the core network device can determine the first information based on the first request information and send the first information to the network device (as shown in S1103-S1104).

[0381] S1102. The core network device sends first request information to the network device; correspondingly, the network device receives the first request information from the core network device.

[0382] Furthermore, the steps performed by the network device according to the first request information may refer to the steps shown in FIG10 , which are not described in detail here.

[0383] S1103. The core network device sends the first information to the network device according to the first request information; correspondingly, the network device receives the first information from the network device.

[0384] The first information is used to indicate a modulation method of the first signal.

[0385] S1104. The network device sends first indication information to the terminal device according to the first information; correspondingly, the terminal device receives the first indication information from the network device.

[0386] It is understood that when the first indication information indicates that the network device allows / supports activation of the second receiver of the terminal device, the terminal device can receive the first signal through the second receiver. Alternatively, when the first indication information indicates that the network device does not allow / support activation of the second receiver of the terminal device, the second receiver of the terminal device is in a dormant state and does not receive the first signal.

[0387] Optionally, the first information may also indicate a first signal, and the network device may directly send the first signal to the terminal device, or the network device may remap the first signal and send the mapped first signal to the terminal device.

[0388] It is understandable that the core network device can also determine whether to allow / support activation of the second receiver of the terminal device based on the first request information. If not allowed / not supported, the core network device does not need to send any information to the network device.

[0389] Based on the communication method shown in Figure 11, the terminal device can send a first request information to the core network device to actively request the network device to send a first signal. This can effectively solve the situation where the terminal device needs to receive the first signal but the network device does not allow / support activation of the second receiver of the terminal device, thereby improving communication performance.

[0390] Based on the communication method shown in Figures 10 and 11, the terminal device may send a first request message before the network device sends the first indication message to request the network device to allow / support activation of the second receiver of the terminal device; or, the terminal device may send a first request message to request the network device to allow / support activation of the second receiver of the terminal device when the first indication message is received and the first indication message indicates not to activate the second receiver of the terminal device, but the terminal device requires the network device to allow / support activation of the second receiver of the terminal device. For example, the network device may expect to modulate the first signal only according to a certain modulation method, but also support modulation of the first signal according to other modulation methods. In this way, even if the second receiver of the terminal device is not compatible with the first signal modulated according to the modulation method expected by the network device, the terminal device can request the network device to send the first signal suitable for its own second receiver.

[0391] Optionally, the present application also proposes a communication method, in which the terminal device can send the capability information of the terminal device to enable the network device to determine whether to allow / support activation of the second receiver of the terminal device. The terminal device can send the capability information of the terminal device to the network device (as shown in Figure 12), or the terminal device can send the capability information of the terminal device to the core network device (as shown in Figure 13).

[0392] The communication method shown in FIG12 may be specifically as follows:

[0393] S1201. The terminal device sends the terminal device capability information to the network device; correspondingly, the network device receives the capability information from the terminal device.

[0394] Among them, the capability information of the terminal device is used to indicate one or more of the following: the demodulation mode supported by the second receiver of the terminal device, the operating frequency supported by the terminal device, the number of operating frequencies supported by the terminal device, and the number of beams supported by the terminal device.

[0395] Optionally, the terminal device may send the capability information of the terminal device to the network device based on the capability reporting process of the terminal device; or, the capability information of the terminal device may be located in the UE auxiliary information; or, the capability information of the terminal device may be transmitted separately without restriction.

[0396] S1202. The network device sends first indication information to the terminal device according to the capability information of the terminal device; correspondingly, the terminal device receives the first indication information from the network device.

[0397] S1203. The terminal device determines whether to activate the second receiver according to the first indication information.

[0398] It is understood that when the network device allows / supports activation of the second receiver of the terminal device, the terminal device can receive the first signal from the network device through the second receiver (as shown in S1204). Alternatively, when the network device does not allow / support activation of the second receiver of the terminal device, the second receiver of the terminal device is in a dormant state (as shown in S1205) and does not receive the first signal.

[0399] Based on the communication method shown in FIG12 , the terminal device can send the terminal device's capability information to the network device, so that the network device can determine whether the network device allows / supports activation of the terminal device's second receiver. At the same time, the network device can assist the network device in determining the first indication information, which can effectively improve the efficiency of information exchange between the terminal device and the network device, thereby improving communication performance. For example, the network device supports modulating the first signal using multiple modulation modes, but can determine which modulation mode or modes to use to modulate the first signal based on the capability information of the terminal devices present in the cell, and send the corresponding first indication information.

[0400] Based on the communication method shown in FIG12 , different from the terminal device sending the terminal device's capability information to the network device, the terminal device can also send the terminal device's capability information to the network device at the request of the network device:

[0401] S1200: The network device sends a second request message to the terminal device; correspondingly, the terminal device receives the second request message from the network device.

[0402] The second request information is used to request the capability information of the terminal device.

[0403] The communication method shown in FIG13 may be specifically as follows:

[0404] S1301. The terminal device sends the terminal device capability information to the core network device; correspondingly, the core network device receives the capability information from the terminal device.

[0405] Among them, the terminal device capability information can refer to the description of the terminal device capability information in the above S1201, which will not be repeated here.

[0406] Optionally, the core network device can forward the capability information of the terminal device to the network device (as shown in S1302 and S1303), or the core network device can determine the first information based on the capability information of the terminal device and send the first information to the network device (as shown in S1304 and S1305).

[0407] S1302. The core network device sends the capability information of the terminal device to the network device. Correspondingly, the network device receives the capability information of the terminal device from the core network device.

[0408] S1303. The network device sends first indication information to the terminal device according to the capability information of the terminal device; correspondingly, the terminal device receives the first indication information from the network device.

[0409] S1304. The core network device sends first information to the network device based on the capability information of the terminal device. Correspondingly, the network device receives the first information from the core network device.

[0410] S1305. The network device sends first indication information to the terminal device according to the first information; correspondingly, the terminal device receives the first indication information from the network device.

[0411] It is understood that when the first indication information indicates that the network device allows / supports activation of the second receiver of the terminal device, the terminal device can receive the first signal through the second receiver. Alternatively, when the first indication information indicates that the network device does not allow / support activation of the second receiver of the terminal device, the second receiver of the terminal device is in a dormant state and does not receive the first signal.

[0412] Optionally, the first information may also indicate a first signal, and the network device may directly send the first signal to the terminal device, or the network device may remap the first signal and send the mapped first signal to the terminal device.

[0413] It is understandable that the core network device can also determine whether to allow / support activation of the second receiver of the terminal device based on the capability information of the terminal device. If not allowed / supported, the core network device does not need to send any information to the network device.

[0414] Based on the communication method shown in Figure 13, the terminal device can send the terminal device's capability information to the core network device, and the core network device can forward it to the network device, or it can indicate to the network device whether to allow / support activation of the second receiver of the terminal device based on the terminal device's capability information.

[0415] Based on the communication method shown in FIG13 , different from the terminal device sending the terminal device capability information to the core network device, the terminal device can also send the terminal device capability information to the core network device at the request of the core network device:

[0416] S1300. The core network device sends a second request message to the terminal device. Correspondingly, the terminal device receives the second request message from the core network device.

[0417] The second request information is used to request the capability information of the terminal device.

[0418] Based on the communication method shown in Figures 10 to 13 above, when the network device agrees to activate the second receiver of the terminal device, the network device can configure different time periods to send the first signal to different terminal devices in different time periods, as shown in Figure 14 below. Taking the first terminal device sending the first request information as an example, the second terminal device is a terminal device that the network device originally allows / supports to activate the second receiver. The network device can send the first signal to the first terminal device in the first cycle (that is, the time period for the first terminal device to receive the first signal is the first cycle), and the second receiver of the second terminal device is in a dormant state; and send the second signal to the second terminal device in the second cycle to the sixth cycle (that is, the time period for the second terminal device to receive the first signal is the second cycle to the sixth cycle), and the second receiver of the first terminal device is in a dormant state.
