Description

Low-power communication method, device and storage medium Cross-reference to related applications

[0001] This application is based on the Chinese Patent Application No. 2024110931094 entitled "Low-power communication method, device and storage medium" filed on August 9, 2024, which is incorporated by reference in its entirety into this application. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, in particular to a low-power communication method, device and storage medium. BACKGROUND

[0003] With the development of wireless cellular communication systems, multi-band, multi-mode and various communication technologies are widely used. In order to support various communication technologies, the device becomes more and more complex on the network device side and the terminal device side, and the corresponding power consumption is also higher and higher, so reducing power consumption has become a problem to be solved.

[0004] In the related art, a low-power radio (LR) module can be added on the terminal device side, which is used to receive the wake-up signal and other low-power signals sent by the network device side. The carrier of the low-power signal is located in the 5G new radio (NR) carrier and occupies part of the bandwidth. The terminal device turns off the main radio (MR) module with higher power consumption by monitoring the low-power signal, and turns on the main radio module when detecting the wake-up command of the terminal device from the network device side, so as to achieve the purpose of saving power.

[0005] However, since the physical resource blocks of the low-power signal carrier and the physical resource blocks of the NR carrier are both basic units of sub-carrier spacing (SCS), for the NR frequency band with non-integer multiple of sub-carrier spacing (for example, the NR carrier of the NR frequency band with 100 kHz channel raster), the physical resource blocks of the low-power signal carrier do not completely align with the physical resource blocks of the low-power signal carrier, which leads to that the channel raster of the NR carrier cannot be equivalent to the low-power signal carrier frequency, and the terminal device needs to scan or receive the low-power signal at any frequency, thereby leading to that the low-power signal carrier cannot be flexibly configured.

[0096] The embodiments of the present application provide a low-power consumption communication method, device and storage medium, which realize flexible configuration of low-power consumption signal carrier.

[0097] Among them, the method and the device are based on the same application concept, and since the principles of the method and the device for solving problems are similar, the implementation of the device and the method can be mutually referred to, and the repeated parts will not be described.

[0098] Firstly, the low-power signal is described below.

[0099] In order to reduce the power consumption of the terminal device, a low-power radio (LR) module can be added to the terminal device. The LR module is used to receive a wake-up signal and other low-power signals sent by the network device side. The carrier of the low-power signal is located in the 5G new radio (NR) carrier and occupies part of the bandwidth. The terminal device closes the main radio (MR) module with higher power consumption by monitoring the low-power signal. When the wake-up command of the network device side to the terminal device is detected, the MR module is opened again, so as to save power.

[0100] Among them, there are two channel grids in the frequency band of the NR carrier. The first one is the NR frequency band based on the sub-carrier spacing (SCS) channel grid (for example, 15 kHz, 30 kHz, 60 kHz), and the other one is the NR frequency band based on the non-integer multiple of sub-carrier spacing (for example, 100 kHz) channel grid.

[0101] For the NR frequency band based on the SCS channel grid, the physical resource block grid of the carrier of the low-power signal is aligned with the physical resource block grid of the NR carrier. Therefore, the carrier of the low-power signal can be flexibly placed on the physical resource block grid in the NR carrier, that is, the frequency generation of the low-power signal can be equivalent to the channel grid of the NR carrier.

[0102] However, for the NR frequency band based on the non-integer multiple of sub-carrier spacing (for example, 100 kHz) channel grid, since the physical resource block of the carrier of the low-power signal and the physical resource block of the NR carrier are both based on SCS as the basic unit, for the NR frequency band based on the non-integer multiple of sub-carrier spacing channel grid, the physical resource block is not completely aligned with the physical resource block grid of the low-power signal carrier, which leads to that the channel grid of the NR carrier cannot be equivalent to the frequency generation of the low-power signal carrier, and the terminal device needs to scan or receive the low-power signal at any frequency, thereby causing the low-power signal carrier to be unable to be flexibly configured.

[0103] To solve the above problems, the embodiments of the present application provide a low-power communication method, device and storage medium. The at least one frequency corresponding to the low-power signal is indicated by the channel grid information of the low-power signal, so that the terminal device can directly receive the low-power signal at the at least one frequency corresponding to the low-power signal indicated by the channel grid information, the terminal device needs to scan or receive the low-power signal at any frequency can be avoided, the complexity of frequency generation is reduced, and the low-power signal carrier is flexibly configured.

[0104] The application scenario of the data transmission method provided by the present application is described below.

[0105] FIG. 1 is a diagram of an application scenario of a low-power consumption communication method provided by an embodiment of the present application. As shown in FIG. 1, communication is performed between a terminal device and a network device. The terminal device comprises an MR module and an LR module, and the power consumption of the MR module is higher than that of the LR module. When the terminal device is in an unawakened state, the LR module is turned on and the MR module is turned off. Subsequently, the terminal device determines at least one frequency corresponding to a low-power consumption signal according to channel raster information of the low-power consumption signal, and receives a first carrier of the low-power consumption signal sent by the network device according to the at least one frequency corresponding to the low-power consumption signal. When the terminal device receives the first carrier of the low-power consumption signal, the MR module can be turned on based on an awakening command in the received low-power consumption signal.

[0106] The channel raster information of the low-power consumption signal is generated based on information of a target frequency band channel raster and a second carrier, the target frequency band channel raster is a non-integer multiple of a subcarrier spacing of the second carrier, and the first carrier is located in the second carrier.

[0107] The terminal device involved in the embodiments of the present application can refer to a device that provides voice and / or data connectivity for a user, a handheld device with wireless connection function, or other processing devices connected to a wireless modem, etc. In different systems, the name of the terminal device can also be different, for example, in the 5G system or the 6G system, the terminal device can be called user equipment (User Equipment, UE). The wireless terminal device can be a USB storage device, other personal computer memory devices and a dongle, and can also communicate with one or more core networks (Core Network, CN) through a radio access network (Radio Access Network, RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or called "cellular" phone) and a computer with a mobile terminal device, for example, it can be a portable, pocket, handheld, computer built-in or vehicle-mounted mobile device, which exchanges language and / or data with the radio access network.

[0108] The network device related to the embodiments of the present application can be a base station, which can include multiple cells serving terminals. According to different application scenarios, the base station can also be referred to as an access point, or can be a device in an access network that communicates with wireless terminal devices through one or more sectors over an air interface, or other names. The network device can be used to exchange received air frames and Internet Protocol (IP) packets as a router between the wireless terminal device and the rest of the access network, which can include an Internet Protocol (IP) communication network. The network device can also coordinate the management of the properties of the air interface. For example, the network device related to the embodiments of the present application can be an evolved network device (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a 5G network architecture, etc., and can also be a home evolved base station (HeNB), a relay node, a femto, a pico, a network test device, etc., which is not limited in the embodiments of the present application.

The various systems can include terminal devices and network devices. The system can also include a core network part, such as an evolved packet system (EPC), a 5G core network (5GC), and the like.

[0110] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0111] In one embodiment, as shown in FIG. 2, a flowchart of a low-power communication method applied to a terminal device is provided for illustrating how the terminal device receives a low-power signal. The low-power communication method includes S201-S202:

[0112] S201, determining at least one frequency corresponding to the low-power signal according to channel raster information of the low-power signal.

[0113] In the present application, before the terminal device receives the low-power signal through the LR module, at least one frequency corresponding to the low-power signal can be determined according to the channel raster information of the low-power signal.

[0114] The channel raster information of the low-power signal is generated based on the information of the channel raster of the target frequency band and the second carrier, and the channel raster of the target frequency band is a non-integer multiple of the subcarrier spacing of the second carrier.

[0115] It should be understood that the carrier is an electric wave modulated and used to carry and transmit information on a communication channel. The second carrier is a basic transmission unit of the communication system, the first carrier is contained in the second carrier, occupies part of the bandwidth, and the first carrier can be a carrier of a low-power signal. For example, if the communication system is a 5G system, the second carrier can be an NR carrier.

[0116] The information of the second carrier includes a subcarrier spacing of the second carrier. The channel raster based on the target frequency band can be a channel raster of the second carrier, and the channel raster of the target frequency band is not an integer multiple of the subcarrier spacing of the second carrier, that is, the target frequency band is not an NR frequency band based on a subcarrier width channel raster. For example, if the second carrier is an NR carrier, the target frequency band can be an NR frequency band of a 100 kHz channel raster.

[0117] In the embodiments of the present application, the channel raster information of the low-power signal can indicate a plurality of frequencies, and the terminal device can determine at least one frequency corresponding to the low-power signal from the plurality of frequencies indicated by the channel raster information of the low-power signal after obtaining the channel raster information of the low-power signal.

[0118] S202, receiving the first carrier of the low-power signal according to the at least one frequency corresponding to the low-power signal.

[0119] In this step, after the terminal device determines the at least one frequency corresponding to the low-power signal, the terminal device can receive the first carrier of the low-power signal according to the at least one frequency corresponding to the low-power signal.

[0120] In the embodiments of the present application, the frequency generator on the LR module in the terminal device can generate the at least one frequency corresponding to the low-power signal. Then, the LR module in the terminal device receives the first carrier of the low-power signal through the generated at least one frequency corresponding to the low-power signal.

[0121] The low-power consumption communication method provided in the embodiments of the present application comprises the following steps: a terminal device first determines at least one frequency corresponding to a low-power consumption signal according to channel raster information of the low-power consumption signal; and then the terminal device receives a first carrier of the low-power consumption signal according to the at least one frequency corresponding to the low-power consumption signal. The channel raster information of the low-power consumption signal is generated based on a channel raster of a target frequency band and information of a second carrier. The channel raster of the target frequency band is a non-integer multiple of a subcarrier spacing of the second carrier, and the first carrier is located in the second carrier. The channel raster information of the low-power consumption signal is set for the second carrier with a non-integer multiple of the subcarrier spacing, and the at least one frequency corresponding to the low-power consumption signal is indicated by the channel raster information of the low-power consumption signal, so that the terminal device can directly receive the low-power consumption signal by using the at least one frequency corresponding to the low-power consumption signal indicated by the channel raster information, and the terminal device can avoid scanning or receiving the low-power consumption signal at any frequency, thereby reducing the complexity of frequency generation and realizing flexible configuration of the low-power consumption signal carrier.

[0122] The following describes how the terminal device determines the channel raster information of the low-power consumption signal. FIG. 3 is a flowchart of another low-power consumption communication method provided in the embodiments of the present application. As shown in FIG. 3, the low-power consumption communication method is applied to a terminal device and comprises the following steps S301-S304:

[0123] S301, obtain configuration information corresponding to channel raster information of a low-power consumption signal, the configuration information being signaling configuration or pre-configuration information.

[0124] The following describes the channel raster information of the low-power consumption signal.

[0125] It should be understood that the channel raster is a regular grid of frequency positions allowed for a carrier of a specific signal in a certain frequency range.

[0126] The channel raster information of the low-power consumption signal is generated based on a channel raster of a target frequency band and information of a second carrier. The channel raster of the target frequency band is a non-integer multiple of a subcarrier spacing of the second carrier, and the first carrier is located in the second carrier.

[0127] In some embodiments, the second carrier is a basic transmission unit corresponding to a communication system, the second carrier contains the first carrier, occupies part of a bandwidth, and the first carrier can be a carrier of the low-power consumption signal. For example, if the communication system is a 5G system, the second carrier can be an NR carrier. For example, if the communication system is a 5G system, the second carrier can be an NR carrier. If the communication system is a 6G system, the second carrier can be a basic transmission carrier corresponding to the 6G system.

[0128] It should be understood that the embodiments of the present application do not limit the bandwidth of the first carrier in the second carrier, for example, the first carrier can occupy 5MHz, 10MHz, etc. in the second carrier.

[0129] In some embodiments, the information of the second carrier can include a subcarrier spacing of the second carrier. The channel raster based on the target frequency band can be a channel raster of the second carrier, and the channel raster of the target frequency band is not an integer multiple of the subcarrier spacing of the second carrier, i.e., the target frequency band is not an NR frequency band based on a subcarrier width channel raster. For example, if the second carrier is an NR carrier, the target frequency band can be an NR frequency band of a 100kHz channel raster.

[0130] In some embodiments, the frequency band is a continuous frequency range in the carrier.

[0131] In some embodiments, the configuration information includes at least one of the following: a frequency corresponding to the second carrier, a maximum number of physical resource blocks of the second carrier, and the parity of the physical resource blocks of the first carrier and the second carrier.

[0132] S302, according to the configuration information, determine the channel raster information of the low-power signal.

[0133] In some embodiments, based on the channel raster of the target frequency band and the information of the second carrier, an expression of the channel raster information of the low-power signal can be generated, and then the terminal device can further determine the channel raster information of the low-power signal through the configuration information corresponding to the channel raster information of the low-power signal.

[0134] For example, the expression of the channel raster information of the low-power signal can be as shown in formula (1):

[0135] cr(t)=n*X+q*SCS*12+m*6*SCS (1)

[0136] Wherein, cr(t) is the channel raster information of the low-power signal, X is the target frequency band, for example, 100kHz; SCS is the subcarrier spacing of the second carrier, which is indicated by the information of the second carrier; n is a positive integer, corresponding to the frequency corresponding to the second carrier; q is an integer, which is an integer within a range of half of the maximum number of physical resource blocks of the second carrier; m is determined according to the parity of the physical resource blocks of the first carrier and the second carrier, and takes 1 or 1.

[0137] For example, if the maximum number of physical resource blocks of the second carrier is 273, the minimum value of q is -floor(273 / 2)=-136, and the maximum value of q is floor(273 / 2)=136.

[0138] It should be understood that after the terminal device generates the expression of the channel raster information of the low-power consumption signal shown in formula (1) through the target frequency band X and the subcarrier spacing SCS of the second carrier, the terminal device can obtain configuration information corresponding to the channel raster information of the low-power consumption signal, and the configuration information can include at least one of n, q, and m, so as to be substituted into formula (1) to determine the channel raster information of the low-power consumption signal.

[0139] For example, the second carrier is an NR carrier, and the target frequency band is 100 kHz. The parity of the physical resource blocks of the first carrier and the second carrier is described.

[0140] FIG. 4 is a schematic diagram of a physical resource block provided by an embodiment of the present application. As shown in FIG. 4, the physical resource blocks of the second carrier are even, and the physical resource blocks of the first carrier are odd. At this time, the channel raster of the target frequency band is located on an integer multiple of 100 k, and the physical resource blocks of the first carrier need to be aligned with the physical resource blocks of the second carrier. Therefore, the center frequency point of the first carrier is different from the center frequency point of the second carrier by q*SCS*12+6*SCS, where q is an integer. That is, when the physical resource blocks of the second carrier are even and the physical resource blocks of the first carrier are odd, m in formula (1) is 1.

[0141] FIG. 5 is another schematic diagram of a physical resource block provided by an embodiment of the present application. As shown in FIG. 5, the physical resource blocks of the second carrier are even, and the physical resource blocks of the first carrier are even. Similarly, the channel raster of the target frequency band is located on an integer multiple of 100 k, and the physical resource blocks of the first carrier need to be aligned with the physical resource blocks of the second carrier. Therefore, the center frequency point of the first carrier is different from the center frequency point of the second carrier by q*SCS*12, where q is an integer. That is, when the physical resource blocks of the second carrier are even and the physical resource blocks of the first carrier are even, m in formula (1) is 0.

[0142] FIG. 6 is a schematic diagram of still another physical resource block provided by an embodiment of the present application. As shown in FIG. 6, the physical resource blocks of the second carrier are odd, and the physical resource blocks of the first carrier are odd. Similarly, the channel raster of the target frequency band is located on an integer multiple of 100 k, and the physical resource blocks of the first carrier need to be aligned with the physical resource blocks of the second carrier. Therefore, the center frequency point of the first carrier is different from the center frequency point of the second carrier by q*SCS*12, where q is an integer. That is, when the physical resource blocks of the second carrier are odd and the physical resource blocks of the first carrier are odd, m in formula (1) is 0.

[0143] FIG. 7 is a schematic diagram of another physical resource block provided by an embodiment of the present application. As shown in FIG. 7, the physical resource block of the second carrier is odd and the physical resource block of the first carrier is even. At this time, the channel raster of the target frequency band is located on an integer multiple of 100k, and the physical resource block of the first carrier needs to be aligned with the physical resource block of the second carrier. Therefore, the center frequency of the first carrier and the center frequency of the second carrier differ by q*SCS*12+6*SCS, where q is an integer. That is, when the physical resource block of the second carrier is odd and the physical resource block of the first carrier is even, m in formula (1) is 1.

[0144] S303, determining at least one frequency corresponding to the low-power consumption signal according to the channel raster information of the low-power consumption signal.

[0145] In some embodiments, the raster information of the low-power consumption signal is used to indicate a frequency set of the low-power consumption signal, and the frequency set includes at least one frequency. After the terminal device acquires the frequency set, the terminal device can select a frequency from the frequency set to determine at least one frequency corresponding to the low-power consumption signal.

[0146] Correspondingly, after the terminal device generates the expression of the channel raster information of the low-power consumption signal and determines the channel raster information of the low-power consumption signal through the configuration information, since the frequency n corresponding to the second carrier is multiple, the parameter q determined by the maximum number of physical resource blocks of the second carrier is also multiple, and therefore the frequency corresponding to the channel raster information of the low-power consumption signal can be multiple and can be indicated by the raster information of the low-power consumption signal.

[0147] In some embodiments, the terminal device can receive indication information of the subcarrier spacing of the second carrier. Subsequently, the terminal device can select a frequency from the frequency set indicated by the channel raster information of the low-power consumption signal according to the indication information of the subcarrier spacing to determine an effective frequency in the frequency set corresponding to the subcarrier spacing. Finally, the terminal device can determine the effective frequency in the frequency set corresponding to the subcarrier spacing as at least one frequency corresponding to the low-power consumption signal.

[0148] The indication information of the subcarrier spacing can be sent by the network device to the terminal device, and the indication information of the subcarrier spacing can be carried in a broadcast channel or configured to the terminal device through signaling. The embodiments of the present application do not limit this.

[0149] For example, if the communication system is a 5G system, the broadcast channel can be an NR broadcast channel.

[0150] The effective frequency can be a frequency meeting the requirement of the subcarrier spacing.

[0151] For example, if the subcarrier spacing SCS is 15 kHz, the formula (1) is used to select the frequency set indicated by the formula (1), and the effective frequency after frequency selection can be shown in the formula (2). The formula (2) is simplified, and the effective frequency after frequency selection is shown in the formula (3):

[0152] cr(t)=n*X+q*180kHz+m*90kHz (2)

[0153] cr(t)=n*X+(2q+m)*90kHz=n*X+p*90kHz (3)

[0154] wherein p=2q+m, p is an integer from -272 (2*136) to 272; cr(t) is the effective frequency after frequency selection, X is a target frequency band, for example, 100 kHz; n is a positive integer corresponding to the frequency of the second carrier; q is an integer within a range of half of the maximum physical resource block number of the positive and negative second carrier; m is determined according to the parity of the physical resource block of the first carrier and the second carrier, and is 1 or 1.

[0155] For example, through the formula (3), the set of effective frequencies after frequency selection can be {10 kHz, 20 kHz, 30 kHz, …, m*10 kHz, …}, and the set of effective frequencies is reflected on the channel grid, and the grid points are t*10k, wherein t is a positive integer, and the difference between two adjacent grid points is 10k.

[0156] In the present application, the subcarrier spacing used by the low-power signal is informed to the terminal device through the broadcast channel, so that the terminal device can select the frequency according to the subcarrier spacing, so as to further narrow the specific effective frequency set, thereby reducing the complexity of frequency generation.

[0157] In some embodiments, the channel grid information of the low-power signal includes a range of absolute frequency point numbers corresponding to the frequency set and a grid point step.

[0158] wherein the absolute frequency point number is used to indicate the frequency in the frequency set, and the grid point step is the difference between two adjacent absolute frequency point numbers.

[0159] For example, if the communication system is a 5G system, the absolute frequency point number can be an NR absolute radio frequency channel number (NR-ARFCN). The NR-ARFCN can be used as an identifier of the frequency, and accordingly, the range of the absolute frequency point number is the value range of the NR-ARFCN corresponding to the frequency in the frequency set.

[0160] For example, Table 1 is a schematic table of NR-ARFCN of a frequency corresponding to a low-power signal provided by an embodiment of the present application. Taking the n1 frequency band in 5G NR as an example, the uplink frequency of the n1 frequency band is 1920-1980 MHz, and the downlink frequency is 2110-2170 MHz. Since the low-power signal is a downlink signal (a signal transmitted by a network device to a terminal device), the frequency range corresponding to the low-power signal is 2110-2170 MHz. If the channel raster information of the low-power signal is represented by NR-ARFCN, the NR-ARFCN number corresponding to the grid point of the first signal raster of the low-power signal is 422000, and the NR-ARFCN number corresponding to the grid point of the last signal raster of the low-power signal is 434000. For example, if the target frequency band is 100 Hz, since the NR frequency band of 100 Hz is below 2.7 GHz, the grid point step can be calculated in units of 5k, and the grid point step NREF=t*10k / 5k=2t. That is, when the NR frequency band of 100 Hz is used, the grid point step in the channel raster information of the low-power signal is 2.

[0161] Table 1

[0162] S304, receiving a first carrier of the low-power signal according to at least one frequency corresponding to the low-power signal.

[0163] The low-power signal can include a low-power wake-up signal (LP-WUS) and a low-power synchronization signal (LP-SS). The low-power wake-up signal is used to wake up the main wireless module of the terminal device, and the low-power synchronization signal is used to transmit synchronization information of the network device.

[0164] For example, if the low-power signal is an LP-WUS, the frequency generator on the LR module in the terminal device can generate at least one frequency corresponding to the low-power signal, and then the LR module in the terminal device receives a first carrier of the low-power signal through the generated at least one frequency corresponding to the low-power signal.

[0165] For example, if the low-power signal is an LP-SS, the LR module in the terminal device performs corresponding scanning based on at least one frequency corresponding to the low-power signal to receive a first carrier of the low-power signal.

[0166] The low-power consumption communication method provided in the embodiments of the present application comprises the following steps: a terminal device determines at least one frequency corresponding to a low-power consumption signal according to channel raster information of the low-power consumption signal; and the terminal device receives a first carrier of the low-power consumption signal according to the at least one frequency corresponding to the low-power consumption signal. The channel raster information of the low-power consumption signal is generated based on a channel raster of a target frequency band and information of a second carrier. The channel raster of the target frequency band is a non-integer multiple of a subcarrier spacing of the second carrier, and the first carrier is located in the second carrier. The channel raster information of the low-power consumption signal is set for the second carrier with a non-integer multiple of the subcarrier spacing, and the at least one frequency corresponding to the low-power consumption signal is indicated by the channel raster information of the low-power consumption signal, so that the terminal device can directly receive the low-power consumption signal by using the at least one frequency corresponding to the low-power consumption signal indicated by the channel raster information, and the terminal device can avoid scanning or receiving the low-power consumption signal at any frequency, thereby reducing the complexity of frequency generation and realizing flexible configuration of a low-power consumption signal carrier.

[0167] The following describes how the network device transmits the first carrier of the low-power consumption signal by using the channel raster information of the low-power consumption signal. FIG. 8 is a flowchart of another low-power consumption communication method provided in the embodiments of the present application. As shown in FIG. 8, the low-power consumption communication method is applied to a network device, and the low-power consumption communication method comprises the following steps S401 and S402:

[0168] S401, determining at least one frequency corresponding to a low-power consumption signal according to channel raster information of the low-power consumption signal.

[0169] The channel raster is a regular grid of frequency positions allowed for a carrier of a specific signal in a certain frequency range.

[0170] In the embodiments of the present application, the channel raster information of the low-power consumption signal is generated based on a channel raster of a target frequency band and information of a second carrier. The channel raster of the target frequency band is a non-integer multiple of a subcarrier spacing of the second carrier.

[0171] The carrier is an electric wave transmitted on a communication channel and used to carry and transmit information after being modulated. The second carrier is a basic transmission unit corresponding to a communication system. The second carrier contains the first carrier and occupies part of the bandwidth. The first carrier can be a carrier of the low-power consumption signal. For example, if the communication system is a 5G system, the second carrier can be an NR carrier. If the communication system is a 6G system, the second carrier can be a basic transmission carrier corresponding to the 6G system.

[0172] In some embodiments, the information of the second carrier can include a subcarrier spacing of the second carrier. The channel raster based on the target frequency band can be a channel raster of the second carrier, and the channel raster of the target frequency band can be a non-integer multiple of the subcarrier spacing of the second carrier, i.e., the target frequency band is not an NR frequency band based on a subcarrier width channel raster.

[0173] In some embodiments, the network device is pre-configured with configuration information corresponding to the channel raster information of the low-power signal. The network device can have the configuration information corresponding to the channel raster information of the low-power signal. The configuration information includes at least one of the following: a frequency corresponding to the second carrier, a maximum number of physical resource blocks of the second carrier, and the parity of the physical resource blocks of the first carrier and the second carrier.

[0174] In some embodiments, the network device can also send the configuration information corresponding to the channel raster information of the low-power signal to the terminal device through signaling.

[0175] In some embodiments, the raster information of the low-power signal is used to indicate a frequency set of the low-power signal, and the frequency set includes at least one frequency.

[0176] In some embodiments, the channel raster information of the low-power signal includes a range of absolute frequency point numbers corresponding to the frequency set and a raster point step.

[0177] The absolute frequency point number is used to indicate a frequency in the frequency set, and the raster point step is the difference between two adjacent absolute frequency point numbers.

[0178] In some embodiments, the network device can also send the terminal device with indication information of the subcarrier spacing of the second carrier, and the indication information of the subcarrier spacing is used to select an effective frequency corresponding to the subcarrier spacing from the frequency set indicated by the channel raster information of the low-power signal.

[0179] S402, according to at least one frequency corresponding to the low-power signal, sending a first carrier of the low-power signal to the terminal device.

[0180] The low-power signal can include a low-power wake-up signal (LP-WUS) and a low-power synchronization signal (LP-SS). The low-power wake-up signal is used to wake up the main wireless module of the terminal device, and the low-power synchronization signal is used to transmit the synchronization information of the network device.

[0181] The low-power consumption communication method provided in the embodiments of the present application comprises the following steps: a network device determines at least one frequency corresponding to a low-power consumption signal according to channel raster information of the low-power consumption signal; and the network device sends a first carrier of the low-power consumption signal to a terminal device according to the at least one frequency corresponding to the low-power consumption signal. The channel raster information of the low-power consumption signal is generated based on channel raster of a target frequency band and information of a second carrier. The channel raster of the target frequency band is a non-integer multiple of a subcarrier spacing of the second carrier, and the first carrier is located in the second carrier. The channel raster information of the low-power consumption signal is set for the second carrier with a non-integer multiple of the subcarrier spacing, and the at least one frequency corresponding to the low-power consumption signal is indicated by the channel raster information of the low-power consumption signal. Therefore, the network device can directly send the low-power signal by using the at least one frequency corresponding to the low-power consumption signal indicated by the channel raster information, so that the terminal device does not need to scan or receive the low-power signal at any frequency, the complexity of frequency generation is reduced, and flexible configuration of the low-power consumption signal carrier is realized.

[0182] The interaction process between the terminal device and the network device in the low-power consumption communication process will be described below. FIG. 9 is a signaling interaction diagram of a low-power consumption communication method provided in an embodiment of the present application. As shown in FIG. 9, the low-power consumption communication method comprises the following steps S501-S506:

[0183] S501, the terminal device acquires configuration information corresponding to channel raster information of a low-power consumption signal.

[0184] The configuration information is signaling configuration or pre-configuration information.

[0185] In some embodiments, the configuration information comprises at least one of the following: a frequency corresponding to the second carrier, a maximum number of physical resource blocks of the second carrier, and parity of physical resource blocks of the first carrier and the second carrier.

[0186] S502, the terminal device determines the channel raster information of the low-power consumption signal according to the configuration information.

[0187] The raster information of the low-power consumption signal is used to indicate a frequency set of the low-power consumption signal.

[0188] In some embodiments, the channel raster information of the low-power consumption signal comprises a range of absolute frequency point numbers corresponding to the frequency set and a raster point step. The absolute frequency point number is used to indicate a frequency in the frequency set, and the raster point step is a difference between two adjacent absolute frequency point numbers.

[0189] S503, the network device sends indication information of a subcarrier spacing of the second carrier to the terminal device.

[0190] The indication information of the subcarrier spacing is carried in a broadcast channel.

[0191] S504, the terminal device selects a frequency set indicated by the channel raster information of the low-power signal according to the indication information of the subcarrier spacing, and determines an effective frequency corresponding to the subcarrier spacing in the frequency set.

[0192] S505, the terminal device determines the effective frequency corresponding to the subcarrier spacing in the frequency set as at least one frequency corresponding to the low-power signal.

[0193] S506, the network device sends a first carrier of the low-power signal to the terminal device according to the at least one frequency corresponding to the low-power signal.

[0194] In some embodiments, the low-power signal includes a low-power wake-up signal and a low-power synchronization signal.

[0195] The low-power wake-up signal is used to wake up the main wireless module of the terminal device, and the low-power synchronization signal is used to transmit synchronization information of the network device.

[0196] The low-power communication method provided by the embodiments of the present application is that the terminal device first determines at least one frequency corresponding to the low-power signal according to the channel raster information of the low-power signal. Then, the terminal device receives the first carrier of the low-power signal according to the at least one frequency corresponding to the low-power signal. The channel raster information of the low-power signal is generated based on the channel raster of the target frequency band and the information of the second carrier. The channel raster of the target frequency band is a non-integer multiple of the subcarrier spacing of the second carrier, and the first carrier is located in the second carrier. Since the channel raster information of the low-power signal is set for the second carrier with a non-integer multiple of the subcarrier spacing, the at least one frequency corresponding to the low-power signal is indicated by the channel raster information of the low-power signal, so that the terminal device can directly receive the low-power signal using the at least one frequency corresponding to the low-power signal indicated by the channel raster information, and the terminal device can avoid scanning or receiving the low-power signal at any frequency, thereby reducing the complexity of frequency generation and realizing flexible configuration of the low-power signal carrier.
