Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a signal transmission method, apparatus, terminal, network-side equipment and readable storage medium. Background Art

[0002] At present, for the detection of low-power signals, different terminals have different capabilities of detecting signal waveforms. For example, some terminals can detect On-Off Keying (OOK) signals, some terminals can detect Frequency-Shift Keying (FSK) signals, and some terminals can detect Orthogonal Frequency Division Multiplexing (OFDM) signals, etc. Therefore, when there are terminals with different capabilities of detecting signal waveforms in a cell, the network side device can use a superimposed waveform to send a low-power signal so that each terminal can detect the low-power signal to achieve the advantage of saving signaling overhead, but this will result in low resource utilization efficiency of some terminals (such as terminals that can detect OFDM signals); or, the network side device can use a single waveform that each terminal can detect to send a low-power signal to each terminal according to the ability of each terminal to detect the signal waveform, so as to improve the resource utilization efficiency of the above-mentioned terminals, but this will bring additional signaling overhead.

[0003] Typically, network-side devices can flexibly select the waveform of a low-power signal based on different Radio Resource Control (RRC) states or different resource load conditions. In this case, some terminals may be unable to determine the waveform of the low-power signal sent by the network-side device.

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0035] The terms involved in the embodiments of the present application are explained below.

[0036] 1. Low power consumption terminal

[0037] Currently, the 3rd Generation Partnership Project (3GPP) has introduced a low power wake-up receiver (LP-WUR) and a low power wake-up signal (LP-WUS) in the mobile cellular system in the 18th version (Rel-18) protocol standard.

[0038] Among them, the LP-WUR is a low-power terminal, and the basic working principle of LR-WUR is: the low-power terminal includes a first module and a second module, the first module is a main communication module, which is used to receive and send communication data sent by the sending device, and the second module is a low-power module, which is used to receive the LP-WUS and low-power beacon signal (or low-power hold signal) sent by the sending device. The LP-WUS is used to wake up the main communication module of the LP-WUR, and the low-power beacon signal (or low-power hold signal) is used to provide time reference information and other information for receiving the LP-WUS, and can also provide wake-up link channel quality measurement. Therefore, the above-mentioned first module is always in a closed state and does not transmit any data when it is not awakened by the LP-WUS received by the second module. When downlink data arrives, the second module can detect the LP-WUS sent by the sending device, and the LP-WUS includes the terminal information of the LP-WUR. Then, the second module can trigger the first module to switch from the closed state to the working state, and transmit data through the first module. It should be noted that the second module can be turned on continuously or discontinuously, and the second module can receive LP-WUS and low power beacon signals (or low power maintenance signals) when turned on.

[0039] 2. Low power signal

[0040] Typically, low-power signals may include LP-WUS, low-power beacon signals, low-power hold signals, low-power synchronization signals, low-power parameter signals, etc. The low-power signal may be modulated using an OOK waveform, so that the second module of the LP-WUR may detect the low-power signal using envelope detection, thereby reducing power consumption to microwatt levels.

[0041] Currently, there are two ways for transmitting devices to generate low-power signals: (1) directly generate OOK signals in the time domain; (2) multiplex the OFDM signal generation structure, generate OFDM signals in the frequency domain, and then transform them to the time domain through inverse Fourier transform, thereby indirectly obtaining the OOK signal.

[0042] Among them, the advantage of the second generation method mentioned above is that it can generate OOK signals without increasing the complexity of the sending equipment in the existing mobile communication system. Therefore, it is more suitable for compatibility with the existing mobile system and does not require additional enhancement of the sending equipment.

[0043] 3. Waveform type of low power signal

[0044] At present, in order to reduce the power consumption of LP-WUR and achieve the purpose of power saving, low-power signals are usually sent using simple waveform types, such as the above-mentioned OOK signal, or FSK signal. Therefore, LP-WUR can identify low-power signals through simple energy detection or frequency detection.

[0045] Since OFDM signal modulation is commonly used in existing New Radio (NR) systems, then the OFDM signal generation method can be used to generate OOK signals or FSK signals. For example, the ON part or the OFF part of the OOK signal is represented by different amplitude information, and a constant amplitude OFDM sequence can be used to generate the ON part of the OOK signal, while the OFF part corresponds to no signal transmission; similarly, the FSK signal carries information by sending signals at different frequencies, so a constant amplitude OFDM sequence can be sent at the corresponding frequency, while no signal is sent at other frequencies. Furthermore, the OFDM sequence that generates the ON part can also carry information through a sequence, for example, two sequences represent 0 and 1 information respectively, or four sequences represent 00, 01, 10, and 11 information respectively.

[0046] For LP-WUR that demodulates OOK signals, it can only demodulate the information of the ON / OFF part, but cannot demodulate the OFDM sequence that generates the OOK signal. Similarly, for LP-WUR that demodulates FSK signals, it can only demodulate the frequency point information, but cannot demodulate the OFDM sequence that generates the FSK signal. However, for LP-WUR that demodulates OFDM signals, it can also demodulate the OFDM sequence.

[0047] 4. Other terms

[0048] The terms "first", "second", etc. of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of one type, and the number of objects is not limited, for example, the first waveform type can be one or more. In addition, "or" in the present application represents at least one of the connected objects. For example, "A or B" covers three schemes, namely, Scheme 1: including A but not including B; Scheme 2: including B but not including A; Scheme 3: including both A and B. The character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0049] The term "indication" in this application can be a direct indication (or explicit indication) or an indirect indication (or implicit indication). A direct indication can be understood as the sender explicitly informing the receiver of specific information, operations to be performed, or request results in the sent indication; an indirect indication can be understood as the receiver determining the corresponding information according to the indication sent by the sender, or making a judgment and determining the operation to be performed or the request result according to the judgment result.

[0053] The signal transmission method, apparatus, terminal, network-side device, and readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

[0054] Figure 2 FIG. 1 is a flow chart of a signal transmission method provided by an embodiment of the present application. Figure 2 As shown, a signal transmission method provided in an embodiment of the present application may include the following steps 101 and 102.

[0055] Step 101: A network-side device sends waveform indication information to N terminals.

[0056] In some embodiments of the present application, the network side device may include at least one of the following: a base station, a radio access network (Radio Access Network, RAN) device, a core network device, and an access and mobility management function (Access and Mobility Function, AMF) network element. Of course, the network side device may also be other devices or other network elements, and the embodiments of the present application are not limited here.

[0057] In some embodiments of the present application, for each of the N terminals, a terminal may be any of the following: an electronic device, a low power consumption terminal LP-WUR. Of course, the above-mentioned terminal may also be other devices or other terminals, which is not limited in the embodiments of the present application.

[0058] In an embodiment of the present application, the network side device may send waveform indication information to N terminals separately or uniformly.

[0059] In some embodiments of the present application, when the first module in the N terminals is in an awake state, the network side device may send a first signaling to each terminal separately or uniformly, and the first signaling includes waveform indication information, so that each terminal can receive a first signaling through the first module to receive a waveform indication information. Among them, the first module can specifically be a main communication module, and the first signaling can include at least one of the following: layer (Layer, L) 1 signaling, L2 signaling, radio resource control (Radio Resource Control, RRC) signaling, broadcast signaling.

[0060] In an embodiment of the present application, the above-mentioned waveform indication information is used to indicate the target waveform type used by the network side device to send the first signal, and N is a positive integer.

[0061] It can be understood that the N waveform indication information is used to indicate the target waveform type used by the network side device to send N first signals, each waveform indication information is used for a terminal to determine a first waveform type, and each first waveform type is a waveform type used by a terminal to detect a first signal.

[0062] In some embodiments of the present application, the above-mentioned first signal may include at least one of the following: a low power wake-up signal LP-WUS, a low power beacon signal, a low power hold signal, a low power synchronization signal, and a low power parameter signal.

[0063] In some embodiments of the present application, the target waveform type includes any of the following:

[0064] A second waveform type, where the second waveform type is a waveform type obtained by superimposing at least two waveform types among the candidate waveform types;

[0065] A third waveform type is a waveform type among the candidate waveform types.

[0066] In the embodiment of the present application, the candidate waveform types include at least two of the following: OOK waveform type, FSK waveform type, OFDM waveform type. Of course, the candidate waveform type may also include other waveform types, which are not limited in the embodiment of the present application.

[0067] It can be understood that the second waveform type mentioned above can be a superimposed waveform type, and the third waveform type mentioned above can be a single waveform type.

[0068] In some embodiments of the present application, when the target waveform type includes the second waveform type, the at least two waveform types are indicated by waveform indication information.

[0069] In this way, it can be seen that since the network side device can first indicate to N terminals the different waveform types used by the network side device to send the first signal, and then send the first signal to the N terminals according to the indicated waveform type, instead of directly sending the first signal to N terminals according to different waveform types, it can avoid the situation where some terminals cannot determine the waveform of the first signal sent by the network side device.

[0070] In the embodiment of the present application, the above-mentioned waveform indication information is used to determine the first waveform type, and the first waveform type is the waveform type used by the terminal to detect the first signal.

[0071] It can be understood that the first waveform type is a waveform type used by the terminal to perform a signal detection operation. It can be understood that each terminal performs a signal detection operation according to the first waveform type determined by each terminal to receive each first signal sent by the network side device to each terminal. The first waveform types determined by different terminals can be the same or different.

[0072] In some embodiments of the present application, the waveform indication information includes at least one of the following:

[0073] Type indication information, where the type indication information is used to indicate the target waveform type;

[0074] A waveform feature sequence, where the waveform feature sequence is at least one feature sequence for generating a first signal.

[0075] Exemplarily, assuming that a certain waveform indication information includes type indication information 1, N terminals include terminal 1, and the type indication information 1 is "01", and the "01" corresponds to the OFDM waveform type and the OOK waveform type, then the target waveform type of the first signal sent by the network side device to terminal 1 is the waveform type obtained by superimposing the OFDM waveform type and the OOK waveform type; or, if the type indication information 1 is "10", and the "10" corresponds to the OFDM waveform type and the FSK waveform type, then the target waveform type of the first signal sent by the network side device to terminal 1 is the waveform type obtained by superimposing the OFDM waveform type and the FSK waveform type; or, if the type indication information 1 is "11", and the "11" corresponds to the OFDM waveform type, the OOK waveform type and the FSK waveform type, then the target waveform type of the first signal sent by the network side device to terminal 1 is the waveform type obtained by superimposing the OFDM waveform type, the OOK waveform type and the FSK waveform type.

[0076] It can be understood that, in the case where the waveform indication information includes type indication information, the network side device can indicate to each terminal in an explicit manner the target waveform type of each first signal sent by the network side device.

[0077] In some embodiments of the present application, the above-mentioned characteristic sequence may include an OFDM sequence. Of course, the waveform characteristic sequence may also include other sequences, which are not limited in the embodiments of the present application.

[0078] In some embodiments of the present application, the network side device can indicate to each terminal the target waveform type of each first signal sent by the network side device through the bits corresponding to the waveform feature sequence. It should be noted that the above "bits corresponding to the waveform feature sequence" can be understood as: the bits occupied by at least one feature sequence included in the waveform feature sequence.

[0079] Exemplarily, assuming that a certain waveform indication information includes a waveform feature sequence 2, and at least one feature sequence included in the waveform feature sequence 2 occupies 1 bit, and N terminals include terminal 2, then the target waveform type of the first signal sent by the network side device to terminal 2 is a waveform type corresponding to 1 bit; or, assuming that the waveform indication information includes a waveform feature sequence 3, and at least one feature sequence included in the waveform feature sequence 3 occupies 2 bits, and N terminals include terminal 3, then the target waveform type of the first signal sent by the network side device to terminal 3 is another waveform corresponding to 2 bits.

[0080] It can be understood that, in the case where the waveform indication information includes a waveform characteristic sequence, the network side device can indicate the target waveform type of each first signal of the network side device to each terminal in an implicit manner.

[0081] In some embodiments of the present application, when the waveform indication information includes a waveform feature sequence, the first information may also include information carried by the waveform feature sequence, wherein the information may be bit information or the like.

[0082] Thus, it can be known that the network side device can carry different information in the waveform indication information, so as to flexibly indicate to the N terminals the type of waveform used by the network side device to send the first signal.

[0083] Step 102: The network-side device sends a first signal to N terminals according to the target waveform type.

[0084] It can be understood that the network side device can send each first signal to each terminal separately or uniformly according to the target waveform type indicated by each waveform indication information.

[0085] In the embodiment of the present application, the number of the above-mentioned target waveform types may be a positive integer less than or equal to N. Wherein, when the number of target waveform types is 1, the target waveform types of the first signal sent by the network side device to the N terminals may all be the same; when the number of target waveform types is N, the target waveform types of the first signal sent by the network side device to the N terminals are all different; when the number of target waveform types is greater than 1 and less than or equal to N, the target waveform types of the first signal sent by the network side device to the N terminals are partially different.

[0086] In some embodiments of the present application, when the network side device cannot obtain the waveform detection capability of N terminals (such as the terminal capability in the following embodiments), the target waveform type of the N first signals sent by the network side device to the N terminals may be the above-mentioned second waveform type. The waveform detection capability is used to indicate the waveform detection type supported by the terminal.

[0087] Optionally, the second waveform types of different first signals sent by the network side device to different terminals may be different. That is, the second waveform types of different first signals may be waveforms obtained by superimposing different waveform types among the candidate waveform types.

[0088] Exemplarily, assuming that the N terminals include terminal 1 and terminal 2, when the network side device is unable to obtain the waveform detection capability of terminal 1 and terminal 2, the network side device can send a first signal to terminal 1 according to the second waveform type 1, and the second waveform type 1 can be a waveform type obtained by superimposing an OOK waveform type and an OFDM waveform type, and the network side device can send a first signal to terminal 2 according to the second waveform type 2, and the second waveform type 2 can be a waveform type obtained by superimposing an FSK waveform type and an OFDM waveform type.

[0089] It can be understood that since the network side device is unable to obtain the waveform detection capability of N terminals, the target waveform type of the N first signals sent by the network side device to the N terminals can be the above-mentioned second waveform type. In this way, when each terminal performs detection according to the waveform type supported by its own waveform detection capability, when any one of the at least two waveform types corresponding to the second waveform type of each first signal is detected, each terminal can receive each first signal according to any one waveform type. Therefore, the situation where a terminal is unable to receive the first signal can be reduced, thereby reducing the situation where the network side device repeatedly sends the first signal, and further reducing the signaling overhead of the network side device.

[0090] In some embodiments of the present application, when the network side device obtains the waveform detection capability of N terminals, the target waveform type of the N first signals sent by the network side device to the N terminals may be the above-mentioned second waveform type or third waveform type.

[0091] Optionally, the second waveform types of different first signals sent by the network side device to different terminals may be different. The third waveform types of different first signals sent by the network side device to different terminals may be different.

[0092] Optionally, the network side device may group the N terminals according to the waveform detection capabilities of the N terminals to obtain different terminal groups, and send the first signal to the terminals in the different terminal groups according to different target waveform types. The waveform detection capabilities of the terminals in each terminal group support detecting the target waveform type of the first signal sent by the network side device to the terminals in each terminal group.

[0093] The embodiment of the present application provides a signal transmission method, in which a network side device can send waveform indication information to N terminals, and the waveform indication information is used to indicate the target waveform type used by the network side device to send a first signal, so that the network side device can send the first signal to the N terminals according to the target waveform type; wherein the waveform indication information is used to determine the first waveform type, and the first waveform type is the waveform type used by the terminal to detect the first signal, and N is a positive integer. Because the network side device can send waveform indication information to the N terminals before sending the first signal to indicate the target waveform type used by the network side device to send the first signal to the N terminals, so that the N terminals can respectively determine the first waveform type used to detect the first signal according to the waveform indication information, instead of directly sending the first signal, therefore, it can be avoided that when the network side device selects different waveform types to send the first signal due to different RRC states or different resource load conditions, the N terminals cannot determine the waveform of the first signal sent by the network side device, which causes the terminal to be unable to determine the waveform type of the first signal, so that the terminal can accurately receive the first signal.

[0094] In some embodiments of the present application, Figure 2 ,like Figure 3 As shown, before the above step 102, the signal transmission method provided in the embodiment of the present application may further include the following step 201, and the above step 102 may be specifically implemented by the following step 102a.

[0095] Step 201: A network-side device groups N terminals to obtain M terminal groups.

[0096] In the embodiment of the present application, M is a positive integer less than or equal to N.

[0097] It should be noted that the embodiment of the present application does not limit the execution order of the above steps 201 and 101. In one example, the network side device may first execute step 201 and then execute step 101; in another example, the network side device may first execute step 101 and then execute step 201; in another example, the network side device may execute step 101 while executing step 201.

[0098] In some embodiments of the present application, the above step 201 can be specifically implemented by at least one of the following steps 201a and 201b.

[0099] Step 201a: The network side device first groups N terminals according to their capabilities, and then groups the terminals in each terminal group obtained by grouping according to a paging occasion (PO) or a paging early indication (PEI) grouping method.

[0100] It can be understood that the N terminal capabilities correspond one-to-one to the N terminals.

[0101] In some embodiments of the present application, for each of the N terminal capabilities, a terminal capability may be any of the following: support for detecting OOK waveform type; support for detecting OOK waveform type and OFDM waveform type; support for detecting FSK waveform type; support for detecting FSK waveform type and OFDM waveform type, support for detecting OOK waveform type, FSK waveform type, and OFDM waveform type. It should be noted that the above-mentioned terminal capability may also be a capability to support detecting other waveform types, which is not limited in the embodiments of the present application.

[0102] In some embodiments of the present application, the network side device may first divide the terminals whose terminal capabilities support detecting OFDM waveform types into one group according to N terminal capabilities, and divide the terminals whose terminal capabilities do not support detecting OFDM waveform types into another group, and then divide the terminals whose terminal capabilities support detecting OOK waveform types in the one group into the same terminal group, and divide the terminals whose terminal capabilities support detecting FSK waveform types in the same terminal group; and then divide the terminals whose terminal capabilities support detecting OOK waveform types in the other group into the same terminal group, and divide the terminals whose terminal capabilities support detecting FSK waveform types in the same terminal group.

[0103] It should be noted that for the description of grouping by PO or PEI grouping method of network side devices, please refer to the specific description in the relevant technology, and the embodiments of the present application will not be repeated here.

[0104] Step 201b: The network side device first groups the N terminals according to the PO or PEI grouping method, and then groups the terminals in each terminal group obtained by grouping according to the capabilities of the N terminals.

[0105] Thus, it can be seen that, since the network side device can first group the N terminals according to the N terminal capabilities, and then group the terminals in the terminal group obtained by the grouping according to the PO or PEI grouping method; or, the network side device can first group the N terminals according to the PO or PEI grouping method, and then group the terminals in the terminal group obtained by the grouping according to the N terminal capabilities, instead of grouping the N terminals in the same way, the flexibility of the network side device in grouping terminals can be improved.

[0106] In some embodiments of the present application, the M terminal groups satisfy at least one of the following:

[0107] The terminal capability supports detection of OFDM waveform type and the terminal is located in X terminal groups, and the terminal capability does not support detection of OFDM waveform type and the terminal is located in Y terminal groups;

[0108] The terminals that support the detection of the OOK waveform type by the terminal capability are located in the same terminal group among the X terminal groups, and the terminals that support the detection of the FSK waveform type by the terminal capability are located in the same terminal group among the X terminal groups;

[0109] The terminal capability supports detecting that the terminals with OOK waveform type are located in the same terminal group among the Y terminal groups, and the terminal capability supports detecting that the terminals with FSK waveform type are located in the same terminal group among the Y terminal groups.

[0110] In the embodiment of the present application, the X terminal groups and the Y terminal groups are: different terminal groups in the M terminal groups, and both X and Y are positive integers less than M.

[0111] Exemplarily, the network side device may first divide the terminals that support OFDM waveform type detection into one group according to N terminal capabilities, and divide the terminals that do not support OFDM waveform type detection into another group, and then divide the terminals that support OOK waveform type detection in the one group into the same terminal group, and divide the terminals that support FSK waveform type detection in the same terminal group, so as to obtain X terminal groups; and then divide the terminals that support OOK waveform type detection in the other group into the same terminal group, and divide the terminals that support FSK waveform type detection in the same terminal group, so as to obtain Y terminal groups. Among them, X terminal groups are subgroups of the above one group, and Y terminal groups are subgroups of the above another group.

[0112] It can be understood that the X terminal groups may include at least one of the following:

[0113] Terminal capabilities support detection of terminal grouping of OFDM waveform types;

[0114] Terminal capabilities support detection of terminal grouping of OFDM waveform type and OOK waveform type;

[0115] Terminal capabilities support detection of terminal grouping of OFDM waveform type and FSK waveform type.

[0116] The Y terminal groups include at least one of the following:

[0117] Terminal capabilities support detection of OOK waveform type terminal grouping;

[0118] Terminal capabilities support detection of terminal grouping of FSK waveform type.

[0119] It can be seen that since the terminal capabilities that support detecting OFDM waveform types also support detecting OOK waveform types or FSK waveform types, the M terminal groups can meet at least one of the above conditions so that the same type of terminals with matching terminal capabilities are located in the same terminal group, so that the network side device can send the first signal to the terminals in each terminal group according to the waveform type that the terminal capabilities of the terminals in each terminal group support detecting. Therefore, the situation where some terminals cannot detect the first signal can be avoided.

[0120] In some embodiments of the present application, before the above step 201, the signal transmission method provided by the embodiment of the present application may further include the following step 301.

[0121] Step 301: The network side device receives terminal capabilities from N terminals respectively.

[0122] In some embodiments of the present application, when the network side device is a base station, the network side device may receive user equipment assistance information (Use Equipment Assistance information, UAI) from N terminals respectively, and the UAI carries terminal capabilities. Alternatively, the network side device may request terminal capabilities from N terminals and receive terminal capabilities from the N terminals respectively.

[0123] In some embodiments of the present application, when the network side device is a core network device, during the process of N terminals performing an initial registration process or a mobility registration process, the network side device may receive terminal capabilities from the N terminals respectively.

[0124] It can be seen that since the network side device can directly receive N terminal capabilities from N terminals respectively, the network side device can accurately group the N terminals according to the N terminal capabilities, so that the terminal capabilities of the terminals in each terminal group support the detection of the target waveform type corresponding to each terminal group.

[0125] Step 102a: The network-side device sends a first signal to each terminal in the M terminal groups according to the M target waveform types.

[0126] In an embodiment of the present application, each terminal group corresponds to a target waveform type, and the terminal capabilities of the terminals in each terminal group support detecting the target waveform type corresponding to each terminal group. The terminal capabilities include waveform detection capabilities, which are used to indicate the waveform detection types supported by the terminal, and M is a positive integer less than or equal to N.

[0127] It can be understood that the number of target waveform types of the above-mentioned N first signals is M.

[0128] In some embodiments of the present application, some of the M target waveform types may be the same or different. For example, two target waveform types corresponding to two terminal groups may be the same or identical.

[0129] It can be seen that since the network side device can group N terminals and send the first signal to the terminal group to which the terminals that support detecting each target waveform type belong according to the terminal capability, each terminal in each terminal group can receive the first signal, thereby avoiding the situation where some terminals cannot receive the first signal.

[0130] In some embodiments of the present application, Figure 3 ,like Figure 4 As shown, after the above step 201 and before the above step 102a, the signal transmission method provided in the embodiment of the present application may further include the following step 401, and the above step 102a may be specifically implemented by the following step 102a1.

[0131] Step 401: A network-side device determines M first time-frequency domain resource sets associated with M terminal groups.

[0132] In the embodiment of the present application, each of the M first time-frequency domain resource sets is respectively associated with a terminal group.

[0133] In some embodiments of the present application, the above-mentioned M first time-frequency domain resource sets meet any of the following conditions: being predefined, being agreed upon by a protocol, and being predetermined by a network-side device.

[0134] Step 102a1: The network-side device sends a first signal to terminals in M ​​terminal groups respectively on M first time-frequency domain resource sets according to M target waveform types.

[0135] It can be seen that since the network side device can determine a first time-frequency domain resource set associated with each terminal group, and send a first signal to the terminals in each terminal group on each first time-frequency domain resource set, each terminal in each terminal group can directly detect the first signal on each first time-frequency domain resource set, without the need for each terminal to continuously detect the first signal, thereby reducing the power consumption of the terminal.

[0136] Of course, in order to enable the terminals in each terminal group to determine a first time-frequency domain resource set associated with each terminal group, the network side device can also send the identifier of the terminal group to which each terminal belongs to each terminal respectively, which will be explained by an example below.

[0137] In some embodiments of the present application, the signal transmission method provided in the embodiments of the present application may further include the following step 501.

[0138] Step 501: The network side device sends the identifier of the terminal group to which each terminal belongs to each terminal.

[0139] In the embodiment of the present application, the identifier of each terminal group is used to determine the time-frequency domain resource set for detecting the network side device sending the first signal.

[0140] In some embodiments of the present application, the identifier of each terminal group may specifically be an identification code (Identifier, ID) of each terminal group.

[0141] In some embodiments of the present application, the network side device may send RRC signaling to each terminal respectively, where the RRC signaling carries an identifier of the terminal group to which the terminal belongs.

[0142] In this way, it can be seen that since the network side device can send the identifier of the terminal group to which it belongs to each terminal respectively, so that each terminal can accurately determine the time-frequency domain resource set for detecting that the network side device sends the first signal, it can reduce the situation where each terminal continues to detect the first signal due to the incorrect determination of the time-frequency domain resource set for detecting that the network side device sends the first signal. In this way, the power consumption of the terminal can be reduced.

[0143] Figure 5 FIG. 1 is a flow chart of a signal transmission method provided by an embodiment of the present application. Figure 5 As shown, a signal transmission method provided in an embodiment of the present application may include the following steps 601 and 602.

[0144] Step 601: The terminal determines a first waveform type according to at least one of waveform indication information and terminal capability.

[0145] It can be understood that the terminal in this embodiment can be any one of the N terminals in the above embodiments.

[0146] In an embodiment of the present application, the above-mentioned waveform indication information is used to indicate the target waveform type used by the network side device to send the first signal, and the above-mentioned terminal capability includes waveform detection capability, which is used to indicate the waveform detection type supported by the terminal.

[0147] In some embodiments of the present application, the above-mentioned first signal may include at least one of the following: a low power wake-up signal LP-WUS, a low power beacon signal, a low power hold signal, a low power synchronization signal, and a low power parameter signal.

[0148] In some embodiments of the present application, the target waveform type includes any of the following:

[0149] A second waveform type, where the second waveform type is a waveform type obtained by superimposing at least two waveform types among the candidate waveform types;

[0150] A third waveform type is a waveform type among the candidate waveform types.

[0151] In an embodiment of the present application, the above-mentioned candidate waveform types include at least two of the following: OOK waveform type, FSK waveform type, and OFDM waveform type.

[0152] In this way, it can be seen that since the terminal can determine the first waveform type used by the terminal to detect the first signal based on the different waveform types used by the network side device to send the first signal and the terminal capability of the waveform detection type supported by the terminal, it can avoid the situation where some terminals are unable to determine the waveform of the first signal sent by the network side device.

[0153] In some embodiments of the present application, the waveform indication information includes at least one of the following:

[0154] Type indication information, where the type indication information is used to indicate the target waveform type;

[0155] A waveform feature sequence, where the waveform feature sequence is at least one feature sequence for generating a first signal.

[0156] It should be noted that, for the description of the above-mentioned type indication information and waveform characteristic sequence, reference may be made to the specific description in the above-mentioned embodiment, and the embodiments of the present application will not be repeated here.

[0157] Thus, it can be known that, in the case where the network-side device carries different information in the waveform indication information, the terminal can still accurately determine the waveform type used to detect the first signal.

[0158] The following will use different examples to illustrate how the electronic device determines the first waveform type.

[0159] Example 1: The terminal determines the first waveform type according to the waveform indication information and the terminal capability.

[0160] In a possible implementation, the waveform indication information includes type indication information. Figure 5 ,like Figure 6 As shown, the above step 601 can be specifically implemented through the following step 601a.

[0161] Step 601a: The terminal determines a first waveform type that the terminal capability supports detection from the target waveform types indicated by the type indication information.

[0162] In some embodiments of the present application, when the target waveform type indicated by the type indication information is the second waveform type, the terminal may determine the first waveform type that the terminal capability supports detection from at least two waveform types. The first waveform type may be at least one waveform type of the at least two waveform types.

[0163] Exemplarily, assuming that the target waveform type indicated by the type indication information is a waveform type obtained by superimposing the OOK waveform type and the OFDM waveform type, if the terminal capability of the terminal supports detecting the OOK waveform type, the terminal can determine the OOK waveform type as the first waveform type, that is, when the terminal detects the first signal, the terminal only detects the OOK waveform type; if the terminal capability of the terminal supports detecting the OOK waveform type and the OFDM waveform type, the terminal can determine the OOK waveform type and the OFDM waveform type as the first waveform type, that is, when the terminal detects the first signal, in addition to detecting the OOK waveform type according to the amplitude information, the terminal also detects the OFDM waveform type at the position corresponding to the ON part of the OOK waveform type.

[0164] As another example, assuming that the target waveform type indicated by the type indication information is a waveform type obtained by superimposing an FSK waveform type and an OFDM waveform type, if the terminal capability of the terminal supports detecting an FSK waveform type, the terminal can determine the FSK waveform type as the first waveform type, that is, when the terminal detects the first signal, the terminal only detects the FSK waveform type; if the terminal capability of the terminal supports detecting an FSK waveform type and an OFDM waveform type, the terminal can determine the FSK waveform type and the OFDM waveform type as the first waveform type, that is, when the terminal detects the first signal, in addition to detecting the FSK waveform type based on the frequency information, it can also detect the OFDM signal.

[0165] In some embodiments of the present application, when the target waveform type indicated by the type indication information is the third waveform type, if the terminal capability supports detecting the third waveform type, the terminal determines the third waveform type as the first waveform type.

[0166] It can be seen that since the terminal can determine the first waveform type that the terminal capability supports detection from the target waveform type indicated by the network side device, the terminal can directly detect the first signal according to the first waveform type to receive the first signal. Therefore, the situation where some terminals are unable to receive the first signal can be avoided.

[0167] In some embodiments of the present application, Figure 5 ,like Figure 7 As shown, before the above step 601, the signal transmission method provided in the embodiment of the present application may further include the following step 701.

[0168] Step 701: The terminal receives a first signaling from a network side device.

[0169] In an embodiment of the present application, the above-mentioned first signaling includes first information; the first signaling includes at least one of the following: L1 signaling, L2 signaling, RRC signaling, and broadcast signaling.

[0170] Example 2: The terminal determines the first waveform type according to the terminal capability.

[0171] In some embodiments of the present application, since the network side device may not send the waveform indication information or the terminal may not receive the waveform indication information, the terminal may directly determine the first waveform type according to the terminal capability. Figure 5 ,like Figure 8 As shown, the above step 601 can be specifically implemented through the following step 601b.

[0172] Step 601b: When the terminal fails to successfully receive the waveform indication information, the terminal determines the default waveform type corresponding to the terminal capability as the first waveform type.

[0173] In the embodiment of the present application, the failure of the terminal to successfully receive the first information may be understood as: the network side device fails to send the waveform indication information, or the terminal fails to receive the waveform indication information.

[0174] In some embodiments of the present application, the above-mentioned default waveform type satisfies any one of the following: a predefined waveform type, a waveform type indicated by a network-side device.

[0175] Wherein, when the default waveform type is a predefined waveform type, a waveform type among the waveform types supported by the terminal capability detection may be defined as the default waveform type. When the default waveform type is a waveform type indicated by the network side device, the network side device may obtain the terminal capability and indicate a waveform type among the waveform types supported by the terminal capability detection as the default waveform type.

[0176] In this way, it can be seen that since the terminal can directly determine the default waveform type corresponding to the terminal capability as the first waveform type when the waveform indication information is not successfully received, the problem that the terminal cannot determine the first waveform type when the waveform indication information is not successfully received can be solved, thereby avoiding the situation where some terminals are unable to receive the first signal.

[0177] Step 602: The terminal detects a first signal according to the first waveform type.

[0178] It should be noted that, for the description of the terminal detecting the first signal, reference may be made to the specific description in the related art, and the embodiments of the present application will not be elaborated here.

[0179] In some embodiments of the present application, the above step 602 can be specifically implemented through the following step 602a.

[0180] Step 602a: The terminal detects a first signal at a first moment according to a first waveform type.

[0181] In the embodiment of the present application, the above-mentioned first moment is: the moment after a preset time period from the moment when the terminal successfully decodes the waveform indication information.

[0182] In some embodiments of the present application, the above-mentioned preset duration may satisfy any of the following: being indicated by a network-side device, being predefined, or being agreed upon by a protocol.

[0183] In this way, it can be seen that since the terminal can detect the first signal according to the first waveform type at the first moment after the preset time length from the moment of successfully decoding the waveform indication information, instead of detecting the first signal according to the first waveform type at the moment of successfully decoding the waveform indication information, it can avoid the situation where the terminal cannot accurately determine the first waveform type due to insufficient time.

[0184] The embodiment of the present application provides a signal transmission method, wherein a terminal can determine a first waveform type according to at least one of waveform indication information and terminal capabilities, wherein the waveform indication information is used to indicate a target waveform type used by a network side device to send a first signal, and the terminal capabilities include waveform detection capabilities, wherein the waveform detection capabilities are used to indicate a waveform detection type supported by the terminal, so that the terminal can directly detect the first signal according to the first waveform type to receive the first signal. Since the terminal can directly determine the first waveform type used to detect the first signal according to at least one of the target waveform type of the first signal sent by the network side device indicated by the network side device and the waveform detection capability indicating the waveform detection type supported by the terminal, the terminal can directly detect the first signal according to the first waveform type to receive the first signal, thus avoiding the situation where the terminal cannot determine the waveform type of the first signal sent by the network side device when the network side device selects different waveform types to send the first signal due to different RRC states or different resource load conditions, thereby enabling the terminal to accurately receive the first signal.

[0185] In some embodiments of the present application, Figure 5 ,like Fig. 9 As shown, the above step 602 can be specifically implemented through the following step 602b.

[0186] Step 602b: The terminal detects a first signal on a first time-frequency domain resource set according to a first waveform type.

[0187] In the embodiment of the present application, the first time-frequency domain resource set is a time-frequency domain resource set associated with the terminal group to which the terminal belongs.

[0188] In some embodiments of the present application, the identifier of the terminal group satisfies any of the following:

[0189] It is calculated based on the terminal identification of the terminal;

[0190] Received from the network side device.

[0191] In some embodiments of the present application, the terminal identifier may specifically be a user equipment UE-ID, so that the terminal may calculate the UE-ID according to a predefined criterion to obtain an identifier of the terminal group.

[0192] In some embodiments of the present application, the terminal may receive RRC signaling from a network side device, and the RRC signaling may include an identifier of the terminal group.

[0193] As can be seen, since the terminal can detect the first signal on the first time-frequency domain resource set associated with the terminal group to which the terminal belongs, without continuing to detect the first signal, the power consumption of the terminal can be reduced.

[0194] In some embodiments of the present application, before the above step 602b, the signal transmission method provided by the embodiment of the present application may further include the following step 801.

[0195] Step 801: The terminal sends terminal capabilities to a network-side device.

[0196] In the embodiment of the present application, the above-mentioned terminal capabilities are used to determine the above-mentioned terminal groupings.

[0197] It can be understood that the above terminal grouping can be determined by the network side device after grouping according to the terminal capabilities.

[0198] It should be noted that for the description of the network side device determining the terminal grouping according to the terminal capabilities, reference may be made to the specific description in the above embodiment, and the embodiments of the present application will not be repeated here.

[0199] In some embodiments of the present application, when the network side device is a base station, the terminal can send UAI to the network side device through the main communication module, and the UAI carries the terminal capabilities. Alternatively, the terminal can send the terminal capabilities to the network side device according to the request of the network side device.

[0200] In some embodiments of the present application, when the network side device is a core network device, when the terminal executes the initial registration process or the mobility registration process, the terminal can send the terminal capabilities to the network side device through the main communication module.

[0201] The signal transmission method provided in the embodiment of the present application may be executed by a signal transmission device. In the embodiment of the present application, the signal transmission device performing the signal transmission method is taken as an example to illustrate the signal transmission device provided in the embodiment of the present application.

[0202] Fig.10 A possible structural diagram of a signal transmission device involved in an embodiment of the present application is shown. Fig.10 As shown, the signal transmission device 50 may include: a determination module 51 and a detection module 52 .

[0203] The determination module 51 is used to determine the first waveform type according to at least one of the waveform indication information and the terminal capability; the waveform indication information is used to indicate the target waveform type used by the network side device to send the first signal, and the terminal capability includes a waveform detection capability, and the waveform detection capability is used to indicate the waveform detection type supported by the signal transmission device 50. The detection module 52 is used to detect the first signal according to the first waveform type.

[0204] An embodiment of the present application provides a signal transmission device. Since the signal transmission device can directly determine the first waveform type used to detect the first signal based on at least one of the target waveform type of the first signal sent by the network side device indicated by the network side device and the waveform detection capability indicating the waveform detection type supported by the signal transmission device, the signal transmission device can directly detect the first signal according to the first waveform type to receive the first signal. Therefore, it can avoid the situation where the signal transmission device cannot determine the waveform of the first signal sent by the network side device when the network side device selects a different waveform type to send the first signal due to different RRC states or different resource load conditions, resulting in the signal transmission device being unable to determine the waveform type of the detected first signal. In this way, the signal transmission device can accurately receive the first signal.

[0205] In one possible implementation, the target waveform type includes any one of the following: a second waveform type, which is a waveform type obtained by superimposing at least two waveform types among the candidate waveform types; a third waveform type, which is a waveform type among the candidate waveform types; wherein the candidate waveform types include at least two of the following: an OOK waveform type, an FSK waveform type, and an OFDM waveform type.

[0206] In a possible implementation, the waveform indication information includes at least one of the following: type indication information, where the type indication information is used to indicate the target waveform type; and a waveform feature sequence, where the waveform feature sequence is at least one feature sequence for generating the first signal.

[0207] In a possible implementation, the waveform indication information includes type indication information. The determination module 51 is specifically configured to determine a first waveform type supported by the terminal capability detection from among target waveform types indicated by the type indication information.

[0208] In a possible implementation, the signal transmission device 50 provided in the embodiment of the present application may further include: a receiving module. The receiving module is used to receive a first signaling from a network side device; the first signaling includes waveform indication information; the first signaling includes at least one of the following: L1 signaling, L2 signaling, RRC signaling, and broadcast signaling.

[0209] In a possible implementation, the determination module 51 is specifically configured to determine the default waveform type corresponding to the terminal capability as the first waveform type when the signal transmission device 50 fails to successfully receive the waveform indication information.

[0210] In a possible implementation, the detection module 52 is specifically configured to detect the first signal according to the first waveform type at a first moment, wherein the first moment is a moment after a preset time period from the moment when the signal transmission device 50 successfully decodes the waveform indication information.

[0211] In a possible implementation, the detection module 52 is specifically used to detect a first signal according to a first waveform type on a first time-frequency domain resource set; the first time-frequency domain resource set is a time-frequency domain resource set associated with a terminal group to which the signal transmission device 50 belongs.

[0212] In a possible implementation, the identifier of the terminal group satisfies any of the following conditions: it is calculated based on the terminal identifier of the signal transmission device 50; and it is received from a network-side device.

[0213] In a possible implementation, the signal transmission device 50 provided in the embodiment of the present application may further include: a sending module. The sending module is used to send the terminal capability to the network side device; the terminal capability is used to determine the terminal grouping.

[0214] The signal transmission device in the embodiment of the present application may be an electronic device, such as an electronic device with an operating system, or a component in an electronic device, such as an integrated circuit or a chip. The electronic device may be a terminal, or may be other devices other than a terminal.

[0216] Fig.11 A possible structural diagram of a signal transmission device involved in an embodiment of the present application is shown. Fig.11 As shown, the signal transmission device 60 may include: a sending module 61.

[0217] The sending module 61 is used to send waveform indication information to N terminals; the waveform indication information is used to indicate the target waveform type used by the network side device to send the first signal, N is a positive integer; and the first signal is sent to the N terminals according to the target waveform type. The above waveform indication information is used to determine the first waveform type, which is the waveform type used by the terminal to detect the first signal.

[0218] An embodiment of the present application provides a signal transmission device. Before sending a first signal, the signal transmission device can send waveform indication information to N terminals to respectively indicate to the N terminals the target waveform type used by the signal transmission device to send the first signal, so that the N terminals can respectively determine the first waveform type used to detect the first signal according to the waveform indication information, instead of directly sending the first signal. Therefore, it can be avoided that when the signal transmission device selects different waveform types to send the first signal due to different RRC states or different resource load conditions, the N terminals cannot determine the waveform of the first signal sent by the signal transmission device, which causes the terminals to be unable to determine the waveform type of the first signal. In this way, the terminals can accurately receive the first signal.

[0219] In one possible implementation, the target waveform type includes any one of the following: a second waveform type, which is a waveform type obtained by superimposing at least two waveform types among the candidate waveform types; a third waveform type, which is a waveform type among the candidate waveform types; wherein the candidate waveform types include at least two of the following: an OOK waveform type, an FSK waveform type, and an OFDM waveform type.

[0223] In one possible implementation, the above-mentioned grouping module is specifically used for any of the following items: first grouping N terminals according to N terminal capabilities, and then grouping the terminals in each terminal group obtained by grouping according to the PO or PEI grouping method; first grouping N terminals according to the PO or PEI grouping method, and then grouping the terminals in each terminal group obtained by grouping according to the N terminal capabilities.

[0225] In a possible implementation, the signal transmission device 60 provided in the embodiment of the present application may further include: a determination module. The determination module is used to determine the M first time-frequency domain resource sets associated with the M terminal groups before the sending module 61 sends the first signal to the terminals in the M terminal groups respectively according to the M target waveform types; each first time-frequency domain resource set is associated with one terminal group respectively. The above-mentioned sending module 61 is specifically used to send the first signal to the terminals in the M terminal groups respectively according to the M target waveform types on the M first time-frequency domain resource sets.

[0226] In a possible implementation, the sending module 61 is further used to send the identifier of the terminal group to which each terminal belongs to each terminal, wherein the identifier of each terminal group is used to determine the time-frequency domain resource set for the detection signal transmission device 60 to send the first signal.
