[0114] In some embodiments, in order to detect LP-WUS normally, the terminal needs to obtain the time and frequency position of the network device sending LP-WUS. Optionally, the terminal can obtain time and frequency synchronization by detecting a synchronization signal. For example, the synchronization signal can reuse an existing SSB, or it can also be a low power synchronization signal (LP-SS). Based on the time and frequency synchronization obtained by SSB (Synchronization Signal / PBCH Block) and / or LP-SS, LP-WUS can directly carry wake-up information.

[0115] In some embodiments, LP-WUS may use ASK (Amplitude Shift Keying) modulation to carry wake-up information. OOK modulation is a special case of ASK modulation. The following description takes OOK as an example. It should be noted that the method can also be extended to ASK modulation. For example, on each OOK symbol, OOK on chip (high level symbol) represents bit 1, and OOK off chip (low level symbol) represents bit 0. LP-WUS information can also be after encoding, each coded bit is mapped to an OOK symbol, such as Manchester coding. For 1 / 2 Manchester coding, information bit 1 can be mapped to 2 coded bits (1,0), and information bit 0 can be mapped to 2 coded bits (0,1). For 1 / 4 Manchester coding, information bit 1 can be mapped to 4 coded bits (1,0,1,0), and information bit 0 can be mapped to 4 coded bits (0,1,0,1). The time domain or frequency domain sequence carried by each OOK symbol (more specifically, each OOK on chip) of LP-WUS can also carry wake-up information. On each OOK on chip, multiple bits of information can be represented by carrying different sequences. For example, if there are a maximum of M optional sequences for carrying information on each OOK on chip, then theoretically, this symbol can carry M types of information. If it corresponds to the number of bits, it can carry floor (log 2 M)bit.

[0116] In some embodiments, LP-WUR can support at least two types. One LP-WUR only supports envelope detection (Envelope Detection) of the OOK symbols of LP-WUS, hereinafter referred to as OOK based LR (Low-Power Receiver). The link performance of this receiver is relatively poor. Another LP-WUR can detect the time domain or frequency domain sequence carried by the OOK symbols of LP-WUS, thereby improving the link performance, hereinafter referred to as OFDM (Orthogonal Frequency Division Multiplexing) based LR.

[0117] In some embodiments, for RRC (Radio Resource Control) idle / inactive state UEs, LP-WUS uses the codepoint method to indicate the UE subgroup to be woken up. And the following two types of codepoints are supported: (1) One codepoint corresponds to one UE subgroup; (2) One codepoint corresponds to all UE subgroups. And it is required that the time-domain / frequency-domain sequence on LP WUS should carry all the information of LP WUS, and OFDM LR can obtain all the information of LP WUS from the OFDM sequence.

[0118] In some embodiments, for OOK modulation, the information can be encoded first, such as Manchester coding, and then each encoded bit is sequentially mapped onto the OOK symbols in the LP-WUS time period D. Accordingly, OOK LR can complete receiving the information only after receiving all the OOK symbols in the LP-WUS time period D. D can be predefined, semi-statically configured or dynamically indicated.

[0119] Optionally, for OFDM LR, because sequence-based detection has better link performance, by detecting the time-domain or frequency-domain sequence carried by the OOK symbols, when the number of candidate sequences on an OOK on chip is greater than 2, only receiving the first part of the entire LP-WUS signal can successfully receive the information. To support this function, the first d-length time period in the LP-WUS signal carries the complete LP-WUS information, where d < D. d can be predefined, semi-statically configured or dynamically indicated. By using this method, OFDM LR can obtain the complete LP-WUS information in advance, so as to start the operation of waking up the MR in advance, or, if the UE is not woken up, the UE can quickly return to the power-saving mode of LP-WUR.

[0120] Let the set of complete LP-WUS information be W. The current standard progress conclusion requires that the time-domain or frequency-domain sequence of the OOK symbols superimposed in the OOK on chip time period d should carry the LP-WUS information W. The time-domain or frequency-domain sequence of the OOK symbols in other parts of LP-WUS except the time period d can also carry the information W. See Figure 1B , W can be sent in the A period of OOK, and then W can be sent again in the period of W - A. Or, see Figure 1C, W can be sent in the A period of OOK, and then W can be sent multiple times in the WA period. Using the above method, for OFDM LR, the time period d before LP-WUS supports early completion of LP-WUS detection. If the channel state of the UE is poor, the terminal can repeatedly receive the wake-up signal, or receive LP-WUS in the entire LP-WUS time period D, thereby improving the detection performance.

[0121] Figure 2A FIG. 1 is an interactive schematic diagram of a method for determining a starting time according to an embodiment of the present disclosure. Figure 2A As shown, the embodiment of the present disclosure relates to a method for determining a starting time, and the method includes:

[0122] Step S2101: The network device sends configuration information to the terminal.

[0123] In some embodiments, the terminal receives configuration information sent by the network device. In some embodiments, step S2101 does not limit the object sent by the network device, that is, the network device sends the configuration information. Optionally, the network device sends the configuration information by broadcasting, or sends the configuration information by other means, which is not limited in the embodiments of the present disclosure.

[0124] In some embodiments, the configuration information is used to configure resources that carry wake-up information for the terminal. Optionally, the wake-up information is used to indicate whether the terminal wakes up from a low-power state. For example, the wake-up information is used to indicate that the terminal wakes up from a low-power state. For another example, the wake-up information is used to indicate that the terminal does not wake up from a low-power state. Optionally, the terminal is in a low-power state, and if the terminal receives the wake-up information, it can determine whether to wake up based on the wake-up information. For example, if the wake-up information received by the terminal is used to indicate that the terminal wakes up from a low-power state, the terminal wakes up. Optionally, the terminal waking up from a low-power state means that the terminal switches the main receiver from a sleep state to a wake-up state. Among them, the wake-up state can also be referred to as a working state.

[0125] In some embodiments, the embodiments of the present disclosure do not limit the name of the configuration information, which may be, for example, resource information, time-frequency information, etc.

[0126] In some embodiments, step S2101 in the disclosed embodiment is an optional step and may not be performed. Alternatively, it can be understood that the network device does not need to configure resources for carrying the wake-up information for the terminal, and the terminal determines the resources for carrying the wake-up information in other ways.

[0127] Step S2102: The network device sends a wake-up signal to the terminal based on the resource carrying the wake-up information.

[0128] In some embodiments, the terminal receives a wake-up signal sent by a network device.

[0129] In some instances, the resource carrying the wake-up information refers to a time-frequency resource. Optionally, the time-frequency resource may include an OOK symbol, or an OFDM sequence corresponding to the OOK symbol. The OFDM sequence may be a sequence in the time domain or a sequence in the frequency domain.

[0130] In some embodiments, the manner of carrying the wake-up information is different, and the resources of carrying the wake-up information are different; wherein the manner of carrying the wake-up information includes:

[0131] (1) The wake-up information is carried by the high and low levels of the OOK symbol.

[0132] In some embodiments, the high level of the OOK symbol is represented by OOK on chip (high level symbol), and the low level of the OOK symbol is represented by OOK off chip (low level symbol). Among them, an OOK on chip and an OOK offchip can be called an OOK on-off chip pair.

[0133] Optionally, on each OOK symbol, OOK on chip (high level symbol) represents bit 1, and OOK off chip (low level symbol) represents bit 0. Optionally, if the original information is 1 / 2 Manchester encoded, the OOK on chip and OOK off chip of each OOK on-off chip pair together indicate one bit of the original information. For example, information bit 1 can be mapped to 2 coded bits (1, 0), and information bit 0 can be mapped to 2 coded bits (0, 1). Optionally, after the original information is 1 / 2 Manchester encoded, the OOK on chip and OOK off chip of every two OOK on-off chip pairs together indicate one bit of the original information. For example, information bit 1 can be mapped to 4 coded bits (1, 0, 1, 0), and information bit 0 can be mapped to 4 coded bits (0, 1, 0, 1).

[0134] For example, if the wake-up information is 111001, it becomes 12 bits after 1 / 2 Manchester encoding. If information bit 1 can be mapped to 2 coded bits (1, 0), and information bit 0 can be mapped to 2 coded bits (0, 1), then it is represented by 101010010110 after 1 / 2 Manchester encoding.

[0135] It should be noted that if the wake-up information is carried in a manner of carrying the wake-up information by using the high and low levels of the OOK symbol, the terminal can receive the wake-up information through the OOK-based LR.

[0136] In some embodiments, the wake-up information in the manner of carrying the wake-up information by the high and low levels of the OOK symbol needs to be Manchester encoded and then carried by the high level symbol and the low level symbol of the OOK symbol.

[0137] In a manner where the wake-up information is carried by the high and low levels of the OOK symbol, the resources carrying the wake-up information are a plurality of OOK high-level symbols and OOK low-level symbols in the time domain.

[0138] (2) The wake-up information is carried by an OFDM sequence on an OOK high-level symbol.

[0139] In some embodiments, the time-frequency resources of the symbol carry an OFDM sequence, and the sequence is used to indicate wake-up information.

[0140] Optionally, the wake-up signal is modulated by ASK to generate symbols corresponding to high and low levels for transmission. For example, the wake-up signal is modulated by OOK to generate OOK symbols. Optionally, the wake-up signal carries the wake-up information through OOK on symbols.

[0141] Optionally, the wake-up signal occupies multiple subcarriers on the same time domain resources, and the OFDM sequence is indicated by multiple subcarriers. For example, if the wake-up signal occupies 12 subcarriers, the wake-up information is indicated by an OFDM sequence with a length of 12. For another example, if the wake-up signal occupies 24 subcarriers, the wake-up information is indicated by an OFDM sequence with a length of 24. It should be noted that the embodiments of the present disclosure are described by way of example, and the present disclosure does not limit the number of subcarriers occupied by the wake-up signal.

[0142] For example, one OOK on chip supports a maximum of 4 OFDM sequences, and each OFDM sequence supports indicating 2 bits of information. See Table 1, which shows the information indicated by different OFDM sequences of the OOK on chip.

[0143] Table 1

[0144]

[0145] In some embodiments, if the wake-up signal includes OFDM sequences included in multiple OOK on chips, the information indicated by the multiple OOK on chips together constitutes the wake-up information. Alternatively, each OOK on chip is used to indicate partial information, and the partial information indicated by all OOK on chips is the wake-up information.

[0146] In some embodiments, the wake-up information carried by the OFDM sequence on the OOK high-level symbol does not need to be Manchester encoded before being carried by the OFDM sequence.

[0147] In a manner where the wake-up information is carried by an OFDM sequence on an OOK high-level symbol, the resource carrying the wake-up signal is an OOK high-level symbol carrying the OFDM sequence.

[0148] It should be noted that the wake-up signal in the embodiment of the present disclosure is a low-power wake-up signal. For example, the low-power wake-up signal is LP-WUS. Optionally, the terminal receives the low-power wake-up signal through a low-power receiver.

[0149] Step S2103: The terminal and the network device determine the start time of the wake-up delay based on the resources used to carry the wake-up information.

[0150] Optionally, the wake-up delay is used to determine the time required for the terminal to wake up from a low power consumption state. Alternatively, the wake-up delay is used to indicate the time required for the terminal to switch from a low power consumption state to an awake state. Alternatively, the wake-up delay is used to indicate the time required for a main receiver of the terminal to switch from a sleep state to an awake state.

[0151] It should be noted that the wake-up delay is defined by the terminal's own capabilities. Alternatively, the wake-up delay refers to the delay configured by the terminal at the factory. Alternatively, the wake-up delay is the delay agreed upon by the communication protocol. In some embodiments, the terminal sends its own wake-up delay to the network device.

[0152] In some embodiments, there are different resources used to carry the wake-up information. There are also multiple ways for the terminal and the network device to determine the start time of the wake-up delay based on the resources used to carry the wake-up information. The different ways are described below.

[0153] The first method is to determine the end time of the last OOK symbol group carrying the wake-up information as the start time.

[0154] The OOK symbol group includes an OOK high level symbol and an OOK low level symbol. It should be noted that if the original wake-up information is 1 bit, it will become 2 bits after Manchester encoding, so there must be an OOK high level symbol and an OOK low level symbol.

[0155] In some embodiments, the first method of determining the start time is applicable to any of the above two methods of carrying the wake-up information, for example, the method of carrying the wake-up information in the high and low levels of the OOK symbol or the method of carrying the wake-up information in the OFDM sequence on the OOK high level symbol.

[0156] The second method is to determine the end time of the last OFDM symbol carrying the wake-up information as the start time.

[0157] In some embodiments, the second method for determining the start time is applicable to any of the above two methods for carrying the wake-up information, for example, the method of carrying the wake-up information with the high and low levels of the OOK symbol or the method of carrying the wake-up information with the OFDM sequence on the OOK high level symbol.

[0158] The third method is to determine the end time of the last time slot carrying the wake-up information as the start time.

[0159] In some embodiments, the third method for determining the start time is applicable to any of the above two methods for carrying the wake-up information, for example, the method of carrying the wake-up information with the high and low levels of the OOK symbol or the method of carrying the wake-up information with the OFDM sequence on the OOK high level symbol.

[0160] For example, see Figure 2B As shown, if the wake-up information is 6 bits, it is 111001, and after 1 / 2 Manchester encoding, it becomes 12 bits. If the OFDM sequence on the OOK high-level symbol is used to carry the wake-up information, each OFDM sequence is used to indicate 2 bits of information, then 3 OFDM sequences on OOK on chip are required to carry all the wake-up information. If the start time is determined according to the first method, the start time is t2, and if the start time is determined according to the second method, the start time is t3. If the start time is determined according to the third method, a time slot includes 14 OFDM symbols, and the start time is the end time of the 14th OFDM symbol.

[0161] If the wake-up information is carried by the high and low levels of the OOK symbol, each group of OOK high-level symbols and OOK low-level symbols can indicate one bit, so 12 bits of OOK high-level symbols and OOK low-level symbols are required. At this time, if the starting time is determined according to the first method, the starting time is t4. If the starting time is determined according to the second method, the starting time is t4. If the starting time is determined according to the determined starting time, a time slot includes 14 OFDM symbols, then the start time is the end time of the 14th OFDM symbol.

[0162] In some embodiments, Figure 2B For example, whether the wake-up information is carried by an OFDM sequence on an OOK high-level symbol or by a high-low level OOK symbol, the same starting time can be agreed upon through a protocol, such as time t4.

[0163] For example, see Figure 2CAs shown, if the wake-up information is 5 bits, it is 11100, and after 1 / 2 Manchester encoding, it becomes 10 bits. If the OFDM sequence on the OOK high-level symbol is used to carry the wake-up information, each OFDM sequence is used to indicate 2 bits of information, then 3 OFDM sequences on OOK on chip are required to carry all the wake-up information. If the start time is determined according to the first method, the start time is t2, and if the start time is determined according to the second method, the start time is t3. If the start time is determined according to the third method, a time slot includes 14 OFDM symbols, and the start time is the end time of the 14th OFDM symbol.

[0164] If the wake-up information is carried by the high and low levels of the OOK symbol, each group of OOK high-level symbols and OOK low-level symbols can indicate one bit, so 10 bits of OOK high-level symbols and OOK low-level symbols are required. At this time, if the starting time is determined according to the first method, the starting time is t4, and if the starting time is determined according to the second method, the starting time is t5. If the starting time is determined according to the determined starting time, a time slot includes 14 OFDM symbols, and the starting time is the end time of the 14th OFDM symbol.

[0165] In some embodiments, Figure 2C For example, whether the wake-up information is carried by an OFDM sequence on an OOK high-level symbol or by a high-low level OOK symbol, the same starting time can be agreed upon through a protocol, such as time t4 or t5.

[0166] It should be noted that the above three methods are applicable to any of the above two methods of carrying wake-up information. For example, the method of carrying wake-up information with the high and low levels of OOK symbols or the method of carrying wake-up information with the OFDM sequence on the OOK high-level symbol. In some embodiments, when the resource carrying the wake-up information includes the OFDM sequence on the OOK high-level symbol, the end time of the last OOK high-level symbol carrying the wake-up information is determined as the start time.

[0167] It should be noted that if the terminal supports the above two bearer modes, the terminal can give priority to the start time determined by the bearer mode with a higher priority based on the priority of the two bearer modes. Alternatively, the terminal can use the start time determined by one bearer mode by default. Alternatively, when the network device configures resources of a bearer mode for the terminal, the start time determined by the bearer mode is used.

[0168] Step S2104: The network device takes the start time as the starting point and sends a paging message and / or data after a wake-up delay.

[0169] In some embodiments, the terminal determines whether to wake up the main receiver based on the wake-up information. Optionally, if the wake-up information received by the terminal is used to indicate waking up the main receiver, the main receiver is woken up based on the wake-up information. Optionally, if the wake-up information received by the terminal is used to indicate not waking up the main receiver, the main receiver is kept in a dormant state based on the wake-up information.

[0170] In some embodiments, the terminal takes the start time as the starting point and monitors the paging message and / or data after the wake-up delay.

[0171] Optionally, after waking up the main receiver, the terminal monitors based on the periodicity of the main receiver to monitor paging messages and / or data.

[0172] In some embodiments, the names of information, etc. are not limited to the names recorded in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "code element", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0173] In some embodiments, "obtain", "obtain", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from high levels, obtaining by self-processing, autonomous implementation, etc.

[0174] In some embodiments, terms such as "send", "transmit", "report", "send", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0175] In some embodiments, terms such as "certain", "preset", "preset", "set", "indicated", "some", "any", and "first" can be interchangeable, and "specific A", "preset A", "preset A", "set A", "indicated A", "some A", "any A", and "first A" can be interpreted as A pre-defined in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., and can also be interpreted as specific A, some A, any A, or first A, etc., but is not limited to this.

[0176] The method for determining the start time involved in the embodiment of the present disclosure may include at least one of steps S2101 to S2104. For example, step S2101 may be implemented as an independent embodiment, step S2102 may be implemented as an independent embodiment, and steps S2103 to S2104 may be implemented as independent embodiments, but are not limited thereto.

[0177] In some embodiments, at least one of steps S2101 to S2104 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0178] In some embodiments, reference may be made to the steps and optional implementation methods of other embodiments recorded before or after the description corresponding to this embodiment, as well as other related parts in the description, which will not be repeated here.

[0179] In the above embodiment, the terminal determines the starting time of the wake-up delay based on the resources used to carry the wake-up information, and then can determine the starting time of the terminal starting to wake up from the low power consumption state, and then can start sending or receiving data after the wake-up delay, which not only improves the accuracy of the terminal waking up from the low power consumption state, but also improves the reliability of the terminal's communication.

[0180] Figure 3 is a flow chart of a method for determining a starting time according to an embodiment of the present disclosure, such as Figure 3 As shown, the embodiment of the present disclosure relates to a method for determining a starting time, and the method includes:

[0181] Step S3101: The terminal and the network device determine the start time of the wake-up delay based on the resources used to carry the wake-up information.

[0182] In some embodiments, the implementation of step S3101 can refer to Figure 2A The implementation method of step S2103 will not be repeated here.

[0183] In some embodiments, the manner of carrying the wake-up information is different, and the resources carrying the wake-up signal are different; wherein the manner of carrying the wake-up information includes:

[0184] The wake-up information is carried by the high and low levels of the OOK symbol; or

[0188] In some embodiments, determining the start time of the wake-up delay based on the resource used to carry the wake-up information includes:

[0189] The end time of the last OFDM symbol carrying the wake-up information is determined as the start time.

[0191] The end time of the last time slot carrying the wake-up information is determined as the start time.

[0192] In some embodiments, the manner of carrying the wake-up information is to carry the wake-up information in an OFDM sequence on an OOK high-level symbol, and the determining the starting time of the wake-up delay based on the resource used to carry the wake-up information includes:

[0193] The end time of the last OOK high-level symbol carrying the wake-up information is determined as the start time.

[0194] In some embodiments, the method is performed by a terminal, and the method further includes:

[0200] In some embodiments, the method is performed by a network device, and the method further includes:

[0201] Taking the start time as the starting point, a paging message and / or data is sent after the wake-up delay.

[0202] Figure 4 is a flow chart of a method for determining a starting time according to an embodiment of the present disclosure, such as Figure 4 As shown, the embodiment of the present disclosure relates to a method for determining a starting time, and the method includes:

[0203] Step S4101: determining a start timing moment of a wake-up delay based on different LRs.

[0204] In some embodiments, the start timing time refers to the start time in the above embodiments.

[0205] For OFDM-based LR using time / frequency domain OFDM sequence for LP WUS information reception,

[0206] Method 1:

[0207] The end time of the last on chip of the time domain / frequency domain OFDM sequence corresponding to the LP WUS information is used as the start timing time of the wake-up delay.

[0208] Method 2:

[0209] The end time of the last OOK on+off chippair where the time domain / frequency domain OFDM sequence corresponding to the LP WUS information is located is used as the start timing time of the wake-up delay.

[0210] Method 3:

[0211] The end time of the last OFDM symbol where the time domain / frequency domain OFDM sequence corresponding to the LP WUS information is located is used as the start timing time of the wake-up delay.

[0212] Method 4:

[0213] The end time of the last slot of the time domain / frequency domain OFDM sequence corresponding to the LP WUS information is used as the start timing time of the wake-up delay.

[0214] For OOK-based LR using OOK on-off symbols for LP WUS information reception,

[0215] Method 1:

[0216] The end time of the last OOK on+off chip pair corresponding to the OOK based LP WUS information is used as the start time of the wake-up delay.

[0217] Method 2:

[0218] The end time of the last OFDM symbol corresponding to the OOK based LP WUS information is used as the start time of the wake-up delay.

[0219] Method 3:

[0220] The end time of the last slot corresponding to the OOK based LP WUS information is used as the start time of the wake-up delay.

[0221] Among them, for OFDM-based LR and OOK-based LR, the same starting timing moment may also be agreed upon, for example, the end time of the last slot corresponding to the LP WUS information is used as the starting timing moment of the wake-up delay.

[0222] The LP WUS information refers to bits after being coded, checked, filled, etc. For example, when repetition is used, the LP WUS information refers to the LP WUS information after repetition. When CRC is used, the LP WUS information refers to the LP WUS information after CRC is added.

[0223] For example, assuming that an OFDM symbol duration contains 4 OOK chips, when Manchester coding is used, one information bit is Manchester-coded to form a chip pair consisting of 1 OOK on chip + 1 OOK off chip. On the 4 OOK chips within an OFDM symbol duration, there must be 2 OOK on chips and 2 OOK off chips. Assuming that there are 4 candidate OFDM sequences on each on chip, the sequence on each onchip can represent 2 bits of information, as shown in Table 2 below. Assume that in the Manchester coding of the OOK-based LP WUS signal, '10' represents 1 and '01' represents 0.

[0224] Table 2

[0225]

[0226] Assuming that the total number of LP WUS bits is 6 bits, 3 on-chip OFDM sequences are required to carry all LP WUS information, and 6 on-off chip pairs are required to carry OOK-based LP WUS information. Assuming that the 6-bit LP WUS information is 111001, it becomes 12 bits after 1 / 2 Manchester encoding, and the LP WUS signal is as follows Figure 2B shown.

[0227] For OFDM-based LR using time / frequency domain OFDM sequence for LP WUS information reception, the timing start time of mode 1 / 2 / 3 corresponds to Figure 2B For OOK-based LR using OOK on-off symbols for LP WUS information reception, the timing start time of mode 1 / 2 corresponds to Figure 2B Medium t4.

[0228] It is also possible to directly stipulate in the protocol that the OFDM-based LR using the time domain / frequency domain OFDM sequence for LP WUS information reception and the OOK-based LR using the OOK on-off symbol for LP WUS information reception have the same timing start time, both corresponding to Figure 2B Medium t4.

[0229] Assuming that the total number of LP WUS bits is 5 bits, 3 on-chip OFDM sequences are required to carry all LP WUS information, and 5 on-off chip pairs are required to carry OOK-based LP WUS information.
