Description

Signal transmission method, device, terminal, network side equipment and readable storage medium

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on July 28, 2023, with application number 202310941910.9 and application name “Signal transmission method, device, terminal, network side equipment and readable storage medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] 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

[0003] Currently, different terminals have different capabilities in detecting low-power signals. 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. Therefore, when there are terminals with different capabilities in 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, thereby saving signaling overhead. However, this will result in lower resource utilization efficiency for some terminals (such as terminals that can detect OFDM signals). Alternatively, the network-side device can use a single waveform that each terminal can detect to send a low-power signal to each terminal based on the signal waveform detection capability of each terminal, thereby improving resource utilization efficiency for the above-mentioned terminals. However, this will incur additional signaling overhead.

[0004] Typically, network-side devices can flexibly select the waveform of the low-power signal according to 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. Therefore, some terminals may be unable to determine the waveform of the low-power signal to be detected, resulting in the terminal being unable to receive the low-power signal.

The waveform indication information is used to determine a first waveform type, where the first waveform type is a waveform type used by the terminal to detect the first signal, and N is a positive integer. Because the network-side device may 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, so that the N terminals can each determine the first waveform type used to detect the first signal based on the waveform indication information, rather than directly sending the first signal, this can avoid a situation where the N terminals are unable to determine the waveform 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, resulting in the terminals being unable to determine the waveform type used to detect the first signal. This allows the terminals to accurately receive the first signal. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0037] The following describes the terms involved in the embodiments of the present application.

[0038] 1. Low-power terminals

[0039] 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.

[0040] Among them, the LP-WUR is a low-power terminal, and the basic working principle of LR-WUR is as follows: 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.

[0041] 2. Low power signal

[0042] 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 the microwatt level.

[0043] Currently, there are two ways for transmitting devices to generate low-power signals: (1) directly generating OOK signals in the time domain; (2) multiplexing the OFDM signal generation structure, generating OFDM signals in the frequency domain and then inverse Fourier transforming them into the time domain, thereby indirectly obtaining the OOK signal.

[0044] Among them, the advantage of the above-mentioned second generation method 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.

[0045] 3. Waveform type of low power signal

[0046] At present, in order to reduce the power consumption of LP-WUR and achieve the purpose of saving power, 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.

[0047] Since OFDM signal modulation is commonly used in existing New Radio (NR) systems, OOK signals or FSK signals can be generated using the OFDM signal generation method. For example, the ON part or OFF part of the OOK signal is represented by different amplitude information. 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, FSK signals carry information by sending signals at different frequencies. Therefore, a constant amplitude OFDM sequence can be sent at the corresponding frequency, while no signal is sent at other frequencies. Furthermore, the OFDM sequence used to generate the ON part can also carry information through sequences, for example, two sequences represent 0 and 1 information respectively, or four sequences represent 00, 01, 10, and 11 information respectively.

[0048] The LP-WUR demodulating an OOK signal can only demodulate the ON / OFF information, but cannot demodulate the OFDM sequence that generates the OOK signal. Similarly, the LP-WUR demodulating an FSK signal can only demodulate the frequency information, but cannot demodulate the OFDM sequence that generates the FSK signal. However, the LP-WUR demodulating an OFDM signal can also demodulate the OFDM sequence.

For example, the first waveform type can be one or more. In addition, "or" in this application represents at least one of the connected objects.

The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0051] The term "indication" in this application can be either 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, the operation to be performed, or the requested result, etc. in the instruction sent; an indirect indication can be understood as the receiver determining the corresponding information based on the instruction sent by the sender, or making a judgment and determining the operation to be performed or the requested result, etc. based on the judgment result.

[0055] 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 some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0056] FIG2 is a flow chart showing a signal transmission method according to an embodiment of the present application. As shown in FIG2 , a signal transmission method according to an embodiment of the present application may include the following steps 101 and 102 .

[0057] Step 101: A network-side device sends waveform indication information to N terminals.

[0058] 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 (RAN) device, a core network device, and an access and mobility management 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 thereto.

[0059] In some embodiments of the present application, for each of the N terminals, one terminal may be any of the following: an electronic device, a low-power terminal LP-WUR. Of course, the above-mentioned one terminal may also be other devices or other terminals, which is not limited in the embodiments of the present application.

[0060] In an embodiment of the present application, the network side device may send waveform indication information to N terminals separately or uniformly.

[0061] In some embodiments of the present application, when a first module in N terminals is in an awake state, a network-side device may send a first signaling to each terminal separately or collectively, the first signaling including waveform indication information, so that each terminal may receive the first signaling through the first module to receive the waveform indication information. Specifically, the first module may be a main communication module, and the first signaling may include at least one of the following: Layer (L) 1 signaling, L2 signaling, Radio Resource Control (RRC) signaling, and broadcast signaling.

[0062] In the 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.

[0063] 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, and 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.

[0064] 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.

[0065] In some embodiments of the present application, the target waveform type includes any one of the following:

[0066] 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;

[0067] A third waveform type is a waveform type among the candidate waveform types.

[0068] In the embodiment of the present application, the candidate waveform types include at least two of the following: OOK waveform type, FSK waveform type, and OFDM waveform type. Of course, the candidate waveform types may also include other waveform types, which are not limited in the embodiment of the present application.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] In the embodiment of the present application, the waveform indication information is used to determine a first waveform type, which is a waveform type used by the terminal to detect the first signal.

[0073] It is understood that the first waveform type described above is the waveform type used by the terminal to perform signal detection operations. It is understood that each terminal performs signal detection operations 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.

[0074] In some embodiments of the present application, the waveform indication information includes at least one of the following:

[0075] Type indication information, where the type indication information is used to indicate the target waveform type;

[0076] A waveform feature sequence, where the waveform feature sequence is at least one feature sequence for generating a first signal.

[0077] 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", 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", 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", 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.

[0078] It can be understood that, in the case where the waveform indication information includes type indication information, the network side device can explicitly indicate to each terminal the target waveform type of each first signal sent by the network side device.

[0079] 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.

[0080] In some embodiments of the present application, the network device may indicate to each terminal the target waveform type of each first signal sent by the network device through the bits corresponding to the waveform feature sequence. It should be noted that the "bits corresponding to the waveform feature sequence" described above can be understood as the bits occupied by at least one feature sequence included in the waveform feature sequence.

[0081] Exemplarily, assuming that a certain waveform indication information includes a waveform feature sequence 2, and the bit occupied by at least one feature sequence included in the waveform feature sequence 2 is 1 bit, and the 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 the bit occupied by at least one feature sequence included in the waveform feature sequence 3 is 2 bits, and the 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.

[0082] It can be understood that, in the case where the waveform indication information includes a waveform feature 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.

[0083] 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.

[0084] As can be seen, the network-side device can carry different information in the waveform indication information to flexibly indicate to the N terminals the waveform type used by the network-side device to send the first signal.

[0085] Step 102: The network-side device sends a first signal to N terminals according to the target waveform type.

[0086] 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.

[0087] In the embodiment of the present application, the number of the target waveform types may be a positive integer less than or equal to N. Specifically, when the number of target waveform types is 1, the target waveform types of the first signals 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 signals sent by the network-side device to the N terminals are all different; and 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 signals sent by the network-side device to the N terminals are partially different.

[0088] In some embodiments of the present application, when the network-side device is unable to obtain the waveform detection capabilities of N terminals (e.g., the terminal capabilities 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 second waveform type described above. The waveform detection capability indicates the waveform detection type supported by the terminal.

[0089] 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.

[0090] Exemplarily, assuming that 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 the OOK waveform type and the 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 the FSK waveform type and the OFDM waveform type.

[0091] 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 detects 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 of the waveform types. Therefore, the situation where a terminal cannot 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.

[0092] 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.

[0093] 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.

[0094] Optionally, the network-side device may group the N terminals into different terminal groups according to the waveform detection capabilities of the N terminals, and send first signals 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 for the first signal sent by the network-side device to the terminals in each terminal group.

[0095] An embodiment of the present application provides a signal transmission method, in which a network device can send waveform indication information to N terminals, where the waveform indication information is used to indicate a target waveform type to be used by the network device to send a first signal, so that the network device can send the first signal to the N terminals according to the target waveform type. The waveform indication information is used to determine a first waveform type, which is a waveform type used by the terminal to detect the first signal, and N is a positive integer. Because the network device can send the waveform indication information to the N terminals before sending the first signal to indicate the target waveform type to be used by the network device to send the first signal, so that the N terminals can each determine the first waveform type to be used to detect the first signal based on the waveform indication information, rather than directly sending the first signal, this can avoid a situation where the N terminals are unable to determine the waveform of the first signal sent by the network device when the network device selects different waveform types to send the first signal due to different RRC states or different resource load conditions, resulting in the terminals being unable to determine the waveform type to detect the first signal. This allows the terminals to accurately receive the first signal.

[0096] In some embodiments of the present application, in combination with Figure 2, as shown in Figure 3, before the above-mentioned step 102, the signal transmission method provided in the embodiment of the present application may further include the following step 201, and the above-mentioned step 102 can be specifically implemented through the following step 102a.

[0097] Step 201: The network-side device groups N terminals to obtain M terminal groups.

[0098] In the embodiment of the present application, M is a positive integer less than or equal to N.

[0099] It should be noted that the present embodiment does not limit the execution order of 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 yet another example, the network-side device may execute step 101 simultaneously with step 201.

[0100] 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.

[0101] Step 201a: The network side device first groups N terminals according to their capabilities, and then groups the terminals in each terminal group obtained according to the paging occasion (PO) or paging early indication (PEI) grouping method.

[0102] It can be understood that the N terminal capabilities correspond one-to-one to the N terminals.

[0103] In some embodiments of the present application, for each of the N terminal capabilities, a terminal capability can be any of the following: support for detecting an OOK waveform type; support for detecting an OOK waveform type and an OFDM waveform type; support for detecting an FSK waveform type; support for detecting an FSK waveform type and an OFDM waveform type; support for detecting an OOK waveform type, an FSK waveform type, and an OFDM waveform type. It should be noted that the aforementioned terminal capability can also be the ability to support detecting other waveform types, which is not limited in the embodiments of the present application.

[0104] In some embodiments of the present application, the network side device can 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 in the one group whose terminal capabilities support detecting OOK waveform types into the same terminal group, and divide the terminals whose terminal capabilities support detecting FSK waveform types into the same terminal group; and then divide the terminals in the other group whose terminal capabilities support detecting OOK waveform types into the same terminal group, and divide the terminals whose terminal capabilities support detecting FSK waveform types into the same terminal group.

[0105] 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 this application will not be repeated here.

[0106] Step 201b: The network side device first groups 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.

[0107] It can be seen that, since the network side device can first group N terminals according to the N terminal capabilities, and then group the terminals in the terminal group obtained by grouping according to the PO or PEI grouping method; or, the network side device can first group N terminals according to the PO or PEI grouping method, and then group the terminals in the terminal group obtained by 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.

[0108] In some embodiments of the present application, the M terminal groups satisfy at least one of the following:

[0109] The terminal capability supports detection of OFDM waveform types and is located within X terminal groups, while the terminal capability does not support detection of OFDM waveform types and is located within Y terminal groups;

[0110] The terminal capability supports detection of terminals with OOK waveform types in the same terminal group among the X terminal groups, and the terminal capability supports detection of terminals with FSK waveform types in the same terminal group among the X terminal groups;

[0111] The terminal capability supports detecting that terminals with OOK waveform types are located in the same terminal group among the Y terminal groups, and the terminal capability supports detecting that terminals with FSK waveform types are located in the same terminal group among the Y terminal groups.

[0112] 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.

[0113] For example, the network-side device can first divide the terminals that support OFDM waveform detection into one group according to N terminal capabilities, and divide the terminals that do not support OFDM waveform detection into another group. Then, in the one group, the terminals that support OOK waveform detection into the same terminal group, and the terminals that support FSK waveform detection into the same terminal group, to obtain X terminal groups. Then, in the other group, the terminals that support OOK waveform detection into the same terminal group, and the terminals that support FSK waveform detection into the same terminal group, to obtain Y terminal groups. The X terminal groups are subgroups of the above-mentioned one group, and the Y terminal groups are subgroups of the above-mentioned other group.

[0114] It is understood that the X terminal groups may include at least one of the following:

[0115] Terminal capabilities support detection of terminal grouping of OFDM waveform types;

[0116] Terminal capabilities support detection of terminal grouping for OFDM waveform type and OOK waveform type;

[0117] Terminal capabilities support detection of terminal grouping for OFDM waveform type and FSK waveform type.

[0118] The Y terminal groups include at least one of the following:

[0119] Terminal capabilities support detection of terminal grouping of OOK waveform types;

[0120] Terminal capabilities support detection of terminal grouping based on FSK waveform type.

[0121] It can be seen that since the terminal capability of the terminal that supports detecting the OFDM waveform type also supports detecting the OOK waveform type or the FSK waveform type, 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 capability of the terminals in each terminal group supports detecting. Therefore, the situation where some terminals cannot detect the first signal can be avoided.

[0122] 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.

[0123] Step 301: The network side device receives terminal capabilities from N terminals respectively.

[0124] 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 (UAI) from N terminals, where the UAI carries terminal capabilities. Alternatively, the network-side device may request terminal capabilities from the N terminals and receive terminal capabilities from the N terminals.

[0125] In some embodiments of the present application, when the network side device is a core network device, when N terminals perform an initial registration process or a mobility registration process, the network side device can receive terminal capabilities from the N terminals respectively.

[0126] 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.

[0127] 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.

[0128] 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 type supported by the terminal, and M is a positive integer less than or equal to N.

[0129] It can be understood that the number of target waveform types of the N first signals is M.

[0130] 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.

[0131] 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 terminal that supports detecting each target waveform type belongs 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.

[0132] In some embodiments of the present application, in combination with Figure 3, as shown in Figure 4, after the above-mentioned step 201 and before the above-mentioned step 102a, the signal transmission method provided by the embodiment of the present application may further include the following step 401, and the above-mentioned step 102a can be specifically implemented through the following step 102a1.

[0133] Step 401: A network-side device determines M first time-frequency domain resource sets associated with M terminal groups.

[0134] In the embodiment of the present application, each of the M first time-frequency domain resource sets is associated with a terminal group.

[0135] 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, or being predetermined by a network-side device.

[0136] Step 102a1: The network-side device sends a first signal to each terminal in the M terminal groups on M first time-frequency domain resource sets according to M target waveform types.

[0137] 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 terminal 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.

[0138] 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 with an example below.

[0139] 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.

[0140] Step 501: The network side device sends the identifier of the terminal group to which each terminal belongs to each terminal.

[0141] 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 first signal sent by the network side device.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] Figure 5 shows a schematic flow chart of a signal transmission method provided by an embodiment of the present application. As shown in Figure 5, a signal transmission method provided by an embodiment of the present application may include the following steps 601 and 602.

[0146] Step 601: The terminal determines a first waveform type according to at least one of waveform indication information and terminal capabilities.

[0147] It can be understood that the terminal in this embodiment can be any one of the N terminals in the above embodiment.

[0148] 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.

[0149] 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.

[0150] In some embodiments of the present application, the target waveform type includes any one of the following:

[0151] 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;

[0152] A third waveform type is a waveform type among the candidate waveform types.

[0153] In an embodiment of the present application, the candidate waveform types include at least two of the following: an OOK waveform type, an FSK waveform type, and an OFDM waveform type.

[0154] 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 cannot determine the waveform of the first signal sent by the network side device.

[0155] In some embodiments of the present application, the waveform indication information includes at least one of the following:

[0156] Type indication information, where the type indication information is used to indicate the target waveform type;

[0157] A waveform feature sequence, where the waveform feature sequence is at least one feature sequence for generating a first signal.

[0158] 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.

[0159] As can be seen, 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.

[0160] The following will use different examples to illustrate how the electronic device determines the first waveform type.

[0161] Example 1: The terminal determines the first waveform type according to the waveform indication information and the terminal capability.

[0162] In a possible implementation, the waveform indication information includes type indication information. Optionally, in combination with FIG5 , as shown in FIG6 , the step 601 can be specifically implemented by the following step 601a.

[0163] Step 601a: The terminal determines a first waveform type supported by the terminal capability detection from the target waveform types indicated by the type indication information.

[0164] 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 a first waveform type supported by the terminal capability 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.

[0165] 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, it 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, it also detects the OFDM waveform type at the position corresponding to the ON part of the OOK waveform type.

[0166] As another example, assuming that the target waveform type indicated by the type indication information is a waveform type obtained by superimposing the FSK waveform type and the OFDM waveform type, if the terminal capability of the terminal supports detecting the 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, it only detects the FSK waveform type; if the terminal capability of the terminal supports detecting the FSK waveform type and the 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 according to the frequency information, it can also detect the OFDM signal.

[0167] 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.

[0168] 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 cannot receive the first signal can be avoided.

[0169] In some embodiments of the present application, in combination with FIG. 5 , as shown in FIG. 7 , before the above-mentioned step 601 , the signal transmission method provided in the embodiment of the present application may further include the following step 701 .

[0170] Step 701: The terminal receives a first signaling from a network-side device.

[0171] 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.

[0172] Example 2: The terminal determines the first waveform type according to the terminal capability.

[0173] In some embodiments of the present application, since the network-side device may not send waveform indication information or the terminal may not receive waveform indication information, the terminal can directly determine the first waveform type based on the terminal's capabilities. Optionally, in conjunction with Figure 5, as shown in Figure 8, the above step 601 can be specifically implemented by the following step 601b.

[0174] 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.

[0175] 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 failing to send the waveform indication information, or the terminal failing to receive the waveform indication information.

[0176] 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.

[0177] 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. Where 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.

[0178] 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 cannot receive the first signal.

[0179] Step 602: The terminal detects a first signal according to the first waveform type.

[0180] 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 relevant technology, which will not be elaborated in detail in the embodiment of the present application.

[0181] In some embodiments of the present application, the above step 602 can be specifically implemented through the following step 602a.

[0182] Step 602a: The terminal detects a first signal at a first moment according to a first waveform type.

[0183] In the embodiment of the present application, the first moment is a moment after a preset time period from the moment when the terminal successfully decodes the waveform indication information.

[0184] In some embodiments of the present application, the above-mentioned preset duration may satisfy any one of the following: being indicated by a network-side device, being predefined, or being agreed upon in a protocol.

[0185] 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.

[0186] An embodiment of the present application provides a signal transmission method, in which a terminal can determine a first waveform type based on at least one of waveform indication information and terminal capabilities, the waveform indication information being used to indicate a target waveform type used by a network-side device to send a first signal, the terminal capabilities including waveform detection capabilities, the waveform detection capabilities being used to indicate waveform detection types 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. Because the terminal can directly determine the first waveform type used to detect the first signal based on at least one of the target waveform type indicated by the network-side device for sending the first signal and the waveform detection capability indicating waveform detection types supported by the terminal, the terminal can directly detect the first signal according to the first waveform type to receive the first signal. This avoids 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 a different waveform type to send the first signal due to different RRC states or different resource load conditions, thereby preventing the terminal from being able to determine the waveform type of the first signal. This allows the terminal to accurately receive the first signal.

[0187] In some embodiments of the present application, in combination with FIG. 5 , as shown in FIG. 9 , the above step 602 may be specifically implemented through the following step 602 b.

[0188] Step 602b: The terminal detects a first signal on a first time-frequency domain resource set according to a first waveform type.

[0189] 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.

[0190] In some embodiments of the present application, the identifier of the terminal group satisfies any of the following:

[0191] It is calculated based on the terminal identification of the terminal;

[0192] Received from the network side device.

[0193] 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.

[0194] 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.

[0195] 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.

[0196] 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.

[0197] Step 801: The terminal sends terminal capabilities to a network-side device.

[0198] In the embodiment of the present application, the terminal capabilities are used to determine the terminal grouping.

[0199] It can be understood that the above-mentioned terminal grouping can be determined by the network side device after grouping according to the terminal capabilities.

[0200] It should be noted that, for the description of the network side device determining the terminal grouping according to the terminal capabilities, reference can be made to the specific description in the above embodiment, and the embodiments of the present application will not be repeated here.

[0201] 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.

[0202] In some embodiments of the present application, when the network side device is a core network device, when the terminal performs an initial registration process or a mobility registration process, the terminal can send terminal capabilities to the network side device through the main communication module.

[0203] The signal transmission method provided in the embodiment of the present application can be executed by a signal transmission device. In the embodiment of the present application, the signal transmission device provided in the embodiment of the present application is described by taking the signal transmission method executed by the signal transmission device as an example.

[0204] FIG10 shows a possible structural diagram of a signal transmission device involved in an embodiment of the present application. As shown in FIG10 , the signal transmission device 50 may include: a determination module 51 and a detection module 52 .

[0205] Determination module 51 is configured to determine a first waveform type based on at least one of waveform indication information and terminal capabilities; the waveform indication information indicates a target waveform type used by the network-side device to transmit the first signal, and the terminal capabilities include waveform detection capabilities, which indicate waveform detection types supported by signal transmission device 50. Detection module 52 is configured to detect the first signal according to the first waveform type.

[0206] 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 different waveform types 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.

[0207] 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.

[0208] 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.

[0209] 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.

[0210] In one 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 configured to receive first signaling from a network-side device; the first signaling includes waveform indication information; and the first signaling includes at least one of the following: L1 signaling, L2 signaling, RRC signaling, and broadcast signaling.

[0211] 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.

[0212] In one 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.

[0213] In one possible implementation, the above-mentioned detection module 52 is specifically used to detect the first signal according to the 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 the terminal group to which the signal transmission device 50 belongs.

[0214] In a possible implementation, the identifier of the terminal group satisfies any one 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.

[0215] In a possible implementation, the signal transmission device 50 provided in the embodiment of the present application may further include: a sending module, wherein the sending module is configured to send terminal capabilities to the network-side device; the terminal capabilities are used to determine the terminal grouping.

[0216] The signal transmission device in the embodiments of the present application can 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 chip. The electronic device can be a terminal, or it can be other devices other than a terminal.

The waveform indication information is used to determine a first waveform type, which is the waveform type used by the terminal to detect the first signal.

[0220] 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 based on the waveform indication information, instead of directly sending the first signal. Therefore, it can avoid the situation where, 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, resulting in the terminals being unable to determine the waveform type of the first signal.

[0225] 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.

[0227] In one 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 configured to determine M first time-frequency domain resource sets associated with the M terminal groups before the sending module 61 sends the first signal to each terminal in the M terminal groups according to the M target waveform types; each first time-frequency domain resource set is associated with one terminal group. The sending module 61 is specifically configured to send the first signal to each terminal in the M terminal groups according to the M target waveform types on the M first time-frequency domain resource sets.

[0228] In a possible implementation, the sending module 61 is further configured to send an identifier of the terminal group to which each terminal belongs to each terminal, wherein the identifier of each terminal group is used to determine a set of time-frequency domain resources for the detection signal transmission device 60 to send the first signal.
