[0148] FIG2 is an interactive schematic diagram showing a signal transmission method according to an embodiment of the present disclosure.

[0149] As shown in FIG2 , the signal transmission method includes:

[0150] In S201 , the network device sends an LP WUS to the terminal.

[0151] In some embodiments, the network device divides the LP WUS information into first information and second information, wherein the LP WUS information is used to determine whether to wake up the MR of the terminal. The first information is part of the LP WUS information, and the second information is information in the LP WUS information other than the first information.

[0152] In some embodiments, the manners of dividing the LP WUS information into the first information and the second information are different in the multiple first time periods.

[0153] In some embodiments, the LP WUS carries the first information during a first time period included in the duration of the LP WUS channel, and the sequence carried by the LP WUS during the first time period indicates the second information. In some possible implementations, the LP WUS carries the first information using ASK modulation during the first time period. In some possible implementations, the LP WUS carries the first information using OOK modulation during the first time period.

[0154] In some embodiments, the LP WUS in the first time period includes at least two OOK symbols, wherein the at least two OOK symbols carry the first information, and a sequence carried by an OOK ON symbol in the at least two OOK symbols is used to indicate the second information.

[0155] In some embodiments, the duration of the first period is less than the duration of the LP WUS channel.

[0156] In some embodiments, the duration of the first time period is the duration of two consecutive OOK symbols, wherein the two consecutive OOK symbols include an OOK ON symbol and an OOK OFF symbol.

[0157] In some embodiments, the duration of the first time period is the duration of multiple OOK symbols mapped to one information bit or multiple information bits after Manchester encoding, wherein the number of the multiple OOK symbols is equal to the inverse of the coding rate.

[0158] In some embodiments, the duration of the first time period is the duration of one OFDM symbol or a plurality of OOK symbols obtained by dividing a plurality of consecutive OFDM symbols.

[0159] In some embodiments, the duration of the first time period is determined in at least one of the following ways: a predefined method; a semi-static configuration; or a dynamic indication from the network device.

[0160] In some embodiments, the length of the sequence is determined in at least one of the following ways: a predefined method; a semi-static configuration; or a dynamic indication from the network device.

[0161] In some embodiments, the terminal receives the LP WUS sent by the network device.

[0162] In S202, the terminal determines first information and second information.

[0163] In some embodiments, the terminal determines that the LP WUS carries the first information in a first time period. In some possible implementations, the terminal determines that the LP WUS carries the first information in OOK modulation in the first time period.

[0164] In some possible implementations, the terminal determines the first information according to an ON / OFF pattern of the at least two OOK symbols in the first time period.

[0165] In some possible implementations, the first time period of the terminal includes multiple OOK ON symbols; a sequence carried by each of the multiple OOK ON symbols is used to indicate a portion of the second information, and multiple sequences carried by the multiple OOK ON symbols are used to jointly indicate the second information. In this case, determining the second information indicated by the sequence carried by the LP WUS in the first time period includes determining the second information based on the joint indication of the multiple sequences carried by the multiple OOK ON symbols in the first time period.

[0166] In some possible implementations, the first time period of the terminal includes multiple OOK ON symbols; a sequence carried by each of the multiple OOK ON symbols is used to indicate the second information. In this case, determining the second information indicated by the sequence carried by the LP WUS in the first time period includes determining the second information based on an indication of any one of multiple sequences carried by the multiple OOK ON symbols in the first time period.

[0167] In some possible implementations, the sequence carried by the OOK ON symbol in the at least two OOK symbols is a non-zero sequence, and the sequence carried by the OOK OFF symbol in the at least two OOK symbols is an all-zero sequence, where the non-zero sequence and the all-zero sequence are concatenated to obtain a first sequence. In this case, determining the second information indicated by the sequence carried by the LP WUS in the first time period includes determining the first information and the second information based on an indication of the first sequence carried by the at least two OOK symbols in the first time period.

[0168] In some embodiments, the terminal determines second information indicated by a sequence carried by the LP WUS within the first time period.

[0169] In some embodiments, the duration of the LP WUS channel includes the first period and the second period. After S201, the method further includes: the terminal determining third information carried by the LP WUS in OOK modulation during the second period, wherein the third information is the same as the second information.

[0170] In some embodiments, the method further includes: the terminal determining fourth information indicated by the sequence carried by the LP WUS within a second time period included in the duration of the LP WUS channel, wherein the fourth information is the LP WUS information; detecting the LP WUS information to determine whether to wake up the MR of the terminal.

[0171] In some embodiments, the method further includes: the terminal determining fifth information indicated by the sequence carried by the LP WUS within a second time period included in the duration of the LP WUS channel, wherein the fifth information is the same as the second information; detecting the LP WUS information to determine whether to wake up the MR of the terminal.

[0172] In S203 , the terminal determines whether to wake up the MR.

[0173] In some embodiments, the terminal determines whether to wake up the MR according to the LP WUS information.

[0174] In some embodiments, the terminal detects the LP WUS information according to the first information and the second information.

[0175] In one possible implementation, the duration of the LP WUS channel includes multiple first time periods; and detecting the LP WUS information based on the first information and the second information includes: detecting the LP WUS information based on the first information carried by the LP WUS in any first time period and the second information indicated by the sequence carried by the LP WUS in any first time period.

[0176] In another possible implementation, the duration of the LP WUS channel includes multiple first time periods; and detecting the LP WUS information based on the first information and the second information includes: jointly processing the first information carried by the LP WUS in the multiple first time periods and the second information indicated by the sequence carried by the LP WUS in the multiple first time periods, to detect the LP WUS information.

[0177] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 to S203. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, step S203 may be implemented as an independent embodiment, steps S201+S202 may be implemented as an independent embodiment, and steps S202+S203 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0178] In some embodiments, steps S201 and S202 may be performed in an interchangeable order or simultaneously.

[0179] In some embodiments, steps S201 , S202 , and S203 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0180] In some embodiments, reference may be made to other optional embodiments described before or after the description corresponding to FIG. 2 .

[0181] The terminal uses the Main Radio (MR) to process data. To save power, the terminal can put the MR into sleep mode and listen for a Wake-Up Signal (WUS). The Wake-Up Signal carries the wake-up information and determines whether to wake the MR. To further save power, a Low-Power Wake-Up Signal (LP WUS) has been introduced.

[0182] In some embodiments, in a power saving state, a MR of a terminal may enter a sleep state. If the terminal receives an LP WUS and the wakeup information carried by the received LP WUS indicates wakeup, the MR of the terminal is awakened to transmit downlink data and / or uplink data. If the terminal does not receive an LP WUS, or if the terminal receives an LP WUS and the wakeup information carried by the received LP WUS indicates not to wakeup, the MR of the terminal remains in the sleep state.

[0183] The MR sleep state may include but is not limited to: ultra-deep sleep state, deep sleep state, light sleep state, and micro sleep state.

[0184] To properly detect the LP WUS, the terminal needs to obtain the time and frequency domain locations of the base station's LP WUS transmissions. The terminal can achieve time and frequency synchronization by detecting synchronization signals. Based on the time domain synchronization achieved with the synchronization signals, the LP WUS can directly carry wake-up information. The synchronization signal can reuse the existing Synchronization Signal / PBCH Block (SSB) or employ a Low-Power Synchronization Signal (LP-SS).

[0185] In some embodiments, the LP WUS can carry wake-up information through amplitude shift keying (ASK) modulation. On-off keying (OOK) modulation is a special case of ASK modulation and can also be called binary amplitude shift keying (2ASK) modulation. For ease of description, the following embodiments of the present disclosure are described illustratively using OOK modulation as an example. This does not represent a particular limitation on the present disclosure, and the embodiments of the present disclosure can also be applied to ASK modulation scenarios.

[0186] For example, a bit "1" may be represented by the OOK ON symbol, and a bit "0" may be represented by the OOK OFF symbol.

[0187] For example, the wake-up information can be encoded using Manchester coding, and each resulting coded bit can be mapped to an OOK symbol. If 1 / 2 Manchester coding is used, one information bit "1" can be encoded as two coded bits (1, 0), and one information bit "0" can be encoded as two coded bits (0, 1). If 1 / 4 Manchester coding is used, one information bit "1" can be encoded as four coded bits (1, 0, 1, 0), and one information bit "0" can be encoded as four coded bits (0, 1, 0, 1).

[0188] In some embodiments, the sequence carried by the LP WUS may also indicate wake-up information. This type of LP WUS is also referred to as an LP WUS based on orthogonal frequency division multiplexing (OFDM). The sequence carried by the LP WUS may be a time domain sequence and / or a frequency domain sequence.

[0189] The terminal needs to use a separate receiver to receive the LP WUS, which is called a low-power wake-up receiver (LP-WUR). In some embodiments, the type of LP-WUR may include at least one of the following: the first type of LP-WUR can use envelope detection to determine the wake-up information carried by the received LP WUS, that is, the wake-up information carried by the LP WUS is determined according to the amplitude or energy level of the LP WUS, hereinafter referred to as OOK LR; the second type of LP-WUR can detect the sequence carried by the LP WUS to determine the wake-up information indicated by the sequence, that is, the received OFDM-based LP WUS can be decoded, hereinafter referred to as OFDM LR.

[0190] Currently, how to improve the detection performance of LP-WUR is a problem that needs to be solved.

[0191] In some embodiments, LP WUS can carry complete wake-up information through OOK modulation, and the terminal can use OOK LR to receive LP WUS and obtain the wake-up information. For example, please refer to Figure 3, which is a schematic diagram of LP WUS carrying wake-up information according to an embodiment of the present disclosure. As shown in Figure 3, D represents the duration of the LP WUS channel (that is, the transmission duration of an LP WUS), and W represents the complete wake-up information; the base station can Manchester encode the wake-up information W and map the obtained coded bits to the OOK symbols in time period D in sequence; the terminal can only obtain the wake-up information W carried by these OOK symbols after receiving all OOK symbols in time period D using OOK LR, and then determine whether to wake up the terminal's MR based on the obtained wake-up information W.

[0192] In the above embodiment, since the OOK LR needs to continuously receive OOK symbols within the duration of the LP WUS channel in order to obtain complete wake-up information, it is not conducive to saving the power consumption of the OOK LR.

[0193] In a first aspect, embodiments of the present disclosure provide a signal transmission method. Figure 4 is a schematic flow chart illustrating a signal transmission method according to an embodiment of the present disclosure. The signal transmission method illustrated in this embodiment can be executed by a terminal.

[0194] In some embodiments, the terminal may support OOK LR and OFDM LR.

[0195] As shown in FIG4 , the signal transmission method may include the following steps:

[0196] In S401, an LP WUS sent by a network device is received.

[0197] In S402, first information carried by the LP WUS in a first time period included in the duration of the LP WUS channel is determined, and second information indicated by a sequence carried by the LP WUS in the first time period is determined, wherein the first information is part of the LP WUS information, and the second information is information in the LP WUS information other than the first information.

[0198] In S403, the LP WUS information is detected according to the first information and the second information to determine whether to wake up the MR of the terminal.

[0199] In some embodiments, the LP WUS carries the first information using ASK modulation during the first time period. In one possible implementation, the LP WUS carries the first information using OOK modulation during the first time period. This disclosure uses OOK modulation as an example for illustrative description and does not specifically limit this disclosure.

[0200] It should be noted that the duration of the LP WUS channel involved in this disclosure can also be described as LP WUS duration, LP WUS detection period, LP WUS detection time period, LP WUS detection location, etc. In addition, it should be noted that the LP WUS information involved in this disclosure can also be described as wake-up information, LP WUS-carried indication information, etc., and this disclosure does not limit this.

[0201] For example, see Figure 5A, which is a schematic diagram illustrating an LP WUS carrying wake-up information according to an embodiment of the present disclosure. As shown in Figure 5A, D represents the duration of the LP WUS channel, d represents the first time period, where d < D, and W represents the complete LP WUS information (hereinafter referred to as the complete information). A terminal can receive an LP WUS sent by a network device. The terminal can use OOK LR to determine that the first information directly carried by the LP WUS using OOK modulation in time period d is A, and can use OFDM LR to determine that the second information indicated by the sequence (overlaid sequence) carried by the LP WUS in time period d is WA. Furthermore, after receiving the OOK symbol in time period d, the terminal can detect the complete information W based on the first information A and the second information WA, and determine whether to wake up the terminal's MR based on the detected complete information W.

[0202] It should be noted that the embodiment shown in FIG. 4 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0203] In some embodiments, the manner of determining the duration of the LP WUS channel may include at least one of the following: a predefined manner; a semi-static configuration; or a dynamic indication.

[0204] In some embodiments, the manner of determining the length of the first time period may include at least one of the following: a predefined manner; a semi-static configuration; or a dynamic indication.

[0205] In some embodiments, the duration of the first period is shorter than the duration of the LP WUS channel. For example, as shown in FIG5A , period D is 8 OOK symbols long, and period d is 2 OOK symbols long.

[0206] In some embodiments, the manner of determining the length of the sequence carried by the LP WUS may include at least one of the following: a predefined manner; a semi-static configuration; or a dynamic indication.

[0207] In some embodiments, the length of the sequence is less than or equal to the length of the first period. For example, as shown in FIG5A , period d is 2 OOK symbols long, indicating that the sequence of the second information WA is 1 OOK symbol long.

[0208] In some embodiments, if the detected LP WUS information indicates wakeup in S403, then the MR of the terminal is determined to be woken up. In further embodiments, if the MR of the terminal is determined to be woken up, the LP-WUR may be switched from its current operating mode to a power saving mode, or the LP-WUR may be switched from its current on state to its off state, thereby saving power consumption of the LP-WUR. Subsequently, when the MR enters a sleep state, the LP-WUR may be switched back to its operating mode or turned back on.

[0209] In some embodiments, if the detected LP WUS information indicates not to wake up in S403, then it is determined not to wake up the MR of the terminal. In further embodiments, if it is determined not to wake up the MR of the terminal, the LP-WUR may be switched from an operating mode to a power saving mode, or the LP-WUR may be switched from a currently enabled state to an disabled state, thereby saving power consumption of the LP-WUR. Subsequently, the LP-WUR may be switched back to an operating mode or enabled again when the next LP WUS channel begins.

[0210] According to embodiments of the present disclosure, a terminal can determine first information directly carried by an LP WUS received during a first time period, as well as second information indicated by a sequence carried by the LP WUS received during the first time period. The terminal can then detect the LP WUS information based on the first and second information and determine whether to wake up the terminal's MR. Thus, by combining OOK LR and OFDM LR, the terminal can obtain complete LP WUS information after receiving OOK symbols in the first time period, without having to wait until all OOK symbols within the duration of the LP WUS channel have been received. This improves LP WUS transmission efficiency and allows the terminal to start waking up the MR in advance, which improves LP-WUS detection performance. It also allows the terminal to return to LP-WUR power saving mode in advance, which helps save LP-WUR power consumption.

[0211] Optionally, the network device may divide LP WUS information into first information and second information, wherein the LP WUS information is used to determine whether to wake up the MR of the terminal. In a further embodiment, the network device may send an LP WUS to the terminal, wherein the LP WUS carries the first information during a first time period included in the duration of the LP WUS channel, and the sequence carried by the LP WUS during the first time period indicates the second information.

[0212] In some embodiments, the duration of the LP WUS channel may include a first period and a second period. In this case, the method may further include determining third information carried by the LP WUS during the second period, where the third information is the same as the second information. In some possible implementations, the terminal determines the third information carried by the LP WUS during the second period using OOK modulation.

[0213] For example, see Figure 5B, which is a schematic diagram illustrating an LP WUS carrying wake-up information according to an embodiment of the present disclosure. As shown in Figure 5B, D represents the duration of the LP WUS channel, d represents a first time period, where d < D, and W represents the complete LP WUS information (hereinafter referred to as the complete information). A terminal can receive an LP WUS sent by a network device. The terminal can use OOK LR to determine that the first information carried by the LP WUS in time period d using OOK modulation is A, and can use OFDM LR to determine that the second information indicated by the sequence (overlaid sequence) carried by the LP WUS in time period d is WA. If the channel state of the terminal is poor, the terminal may not be able to obtain the first information and / or the second information after time period d, and thus cannot obtain the complete information W. In this case, the terminal can use OOK LR to determine that the third information carried by the LP WUS in time period Dd using OOK modulation is WA. Furthermore, the terminal can jointly process the OOK symbols and the sequence they carry in time period D to detect the complete information W, and can determine whether to wake up the terminal's MR based on the detected complete information W.

[0214] It should be noted that the joint processing involved in the present disclosure can also be described as combined detection, joint detection, etc. In one possible implementation, joint processing refers to finding the union of the information that has been obtained. For example, the terminal expects to detect the complete information W within the time period d, but if the channel state in which the terminal is located is poor, then only part of the complete information W may be obtained in the first time period d. Therefore, the terminal can continue to determine the other information within the time period Dd, and can find the union of the partial information obtained within the time period d and the other information obtained within the time period Dd to piece together the complete information W. In another possible implementation, joint processing refers to reasoning or calculating the information that has been obtained. For example, the complete information W contains multiple interrelated data, then the terminal can try to infer or calculate other information that has not been obtained based on the partial information obtained in the entire time period D to obtain the complete information W.

[0215] In some embodiments, the method may further include: determining fourth information indicated by a sequence carried by the LP WUS in a second time period, wherein the fourth information is the LP WUS information; detecting the LP WUS information to determine whether to wake up the MR of the terminal.

[0216] For example, please refer to FIG5C , which is a schematic diagram showing an LP WUS carrying wake-up information according to an embodiment of the present disclosure. As shown in Figure 5C, D represents the duration of the LP WUS channel, d represents the first time period, where d<D, and W represents the complete LP WUS information (referred to as complete information W for short); the terminal can receive the LP WUS sent by the network device, and the terminal can use OOK LR to determine that the first information carried by the LP WUS in the time period d using OOK modulation is A, and can use OFDM LR to determine that the second information indicated by the sequence (overlaid sequence) carried by the LP WUS in the time period d is WA; if the channel state of the terminal is poor, the terminal may not be able to obtain the first information and / or the second information after the time period d, and thus cannot obtain the complete information W, then the terminal can use OOK LR to determine that the third information carried by the LP WUS in the time period Dd using OOK modulation is WA, and can use OFDM LR to determine that the fourth information indicated by the sequence carried by the LP WUS in the time period Dd is W; further, the terminal can jointly process the OOK symbols and the sequence they carry in the time period D to detect the complete information W, and can determine whether to wake up the MR of the terminal based on the detected complete information W.

[0217] In some embodiments, the method may further include: determining fifth information indicated by a sequence carried by the LP WUS in a second time period, wherein the fifth information is the same as the second information; detecting the LP WUS information to determine whether to wake up the MR of the terminal.

[0218] For example, please refer to FIG5D , which is a schematic diagram showing an LP WUS carrying wake-up information according to an embodiment of the present disclosure. As shown in Figure 5D, D represents the duration of the LP WUS channel, d represents the first time period, where d<D, and W represents the complete LP WUS information (referred to as complete information W for short); the terminal can receive the LP WUS sent by the network device, and the terminal can use OOK LR to determine that the first information carried by the LP WUS in the time period d using OOK modulation is A, and can use OFDM LR to determine that the second information indicated by the sequence (overlaid sequence) carried by the LP WUS in the time period d is WA; if the channel state of the terminal is poor, the terminal may not be able to obtain the first information and / or the second information after the time period d, and thus cannot obtain the complete information W, then the terminal can use OOK LR to determine that the third information carried by the LP WUS in the time period Dd using OOK modulation is WA, and can use OFDM LR to determine that the fifth information indicated by the sequence carried by the LP WUS in the time period Dd is WA; further, the terminal can jointly process the OOK symbols and the sequence they carry in the time period D to detect the complete information W, and can determine whether to wake up the MR of the terminal based on the detected complete information W.

[0219] In some embodiments, the duration of the LP WUS channel includes multiple first time periods. In this case, detecting the LP WUS information based on the first information and the second information includes detecting the LP WUS information based on the first information carried by the LP WUS in any first time period and the second information indicated by a sequence carried by the LP WUS in any first time period. In some possible implementations, the manner in which the LP WUS information is divided into the first information and the second information is different within the multiple first time periods.

[0220] For example, please refer to FIG5E , which is a schematic diagram showing an LP WUS carrying wake-up information according to an embodiment of the present disclosure. As shown in Figure 5E, D represents the duration of the LP WUS channel, d1, d2, and d3 respectively represent the first time period, where d1=d2=d3<D, and W represents the complete LP WUS information (referred to as complete information for short); the terminal can receive the LP WUS sent by the network device, and the terminal can use OOK LR to determine that the first information carried by the LP WUS in the time period d1, time period d2, and time period d3 using OOK modulation is A, B, and C, respectively, and can use OFDM LR to determine that the second information indicated by the sequence carried by the LP WUS in the time period d1, time period d2, and time period d3 is WA, WB, and WC, respectively; further, after receiving the OOK symbol in time period d, the terminal can detect the complete information W based on the first information A and the second information WA in time period d1, or detect the complete information W based on the first information B and the second information WB in time period d2, or detect the complete information W based on the first information C and the second information WC in time period d3, and determine whether to wake up the MR of the terminal based on the detected complete information W. The first information A, the first information B and the first information C may be the same or different; correspondingly, the second information WA, the second information WB and the second information WC may be the same or different.

[0221] In some embodiments, the duration of the LP WUS channel includes multiple first time periods. In this case, detecting the LP WUS information based on the first information and the second information includes jointly processing the first information carried by the LP WUS in the multiple first time periods and the second information indicated by the sequence carried by the LP WUS in the multiple first time periods to detect the LP WUS information. In some possible implementations, the manner in which the LP WUS information is divided into the first information and the second information in the multiple first time periods is different.

[0222] For example, as shown in Figure 5E, the terminal can receive the LP WUS sent by the network device, and the terminal can use OOK LR to determine that the first information carried by the LP WUS in OOK modulation in time periods d1, d2, and d3 is A, B, and C respectively, and can use OFDM LR to determine that the second information indicated by the sequence carried by the LP WUS in time periods d1, d2, and d3 is WA, WB, and WC respectively; further, if the channel state of the terminal is poor, the terminal may not be able to obtain the complete information W after time period d1, then the terminal can jointly process the OOK symbols in time periods d1 and d2 and the sequences they carry to detect the complete information W; if the complete information still cannot be detected, the terminal can jointly process the OOK symbols in time periods d1, d2, and d3 and the sequences they carry to detect the complete information W.

[0223] It should be noted that the information W, A, WA, B, WB, C, and WC shown in Figures 5A to 5E are only used to represent the division method for LP WUS information. It can be a single information or an information set including multiple information. This disclosure does not specifically limit this.

[0224] In the embodiment shown above, if the channel state of the terminal is poor and the complete LP WUS information is not detected within the first time period, and the LP WUS detection cannot be completed in advance, the terminal can jointly process the OOK symbols and the sequences they carry within the duration of the entire LP WUS channel, thereby improving the reliability of LP WUS transmission and improving the detection performance of LP-WUS.

[0225] In some embodiments, the LP WUS in the first time period includes at least two OOK symbols, and the specific duration of the first time period can be determined by at least one of the following methods:

[0226] Mode 1: The duration of the first time period is the duration of two consecutive OOK symbols, wherein the two consecutive OOK symbols include an OOK ON symbol and an OOK OFF symbol.

[0227] For example, see Figure 6A, which is a schematic diagram illustrating the duration of a first time period and a sequence length according to an embodiment of the present disclosure. As shown in Figure 6A, "1" represents an OOK ON symbol, "0" represents an OOK OFF symbol, and the duration of time period d is the duration of two consecutive OOK symbols.

[0228] Method 2: The duration of the first time period is the duration of multiple OOK symbols mapped to one information bit or multiple information bits after Manchester encoding, where the number of the multiple OOK symbols is equal to the inverse of the coding rate.

[0229] If the coding rate is 1 / X, one or more information bits are mapped to X OOK symbols after Manchester encoding, and the duration of period d can be the duration of X OOK symbols. X can be 2, 4, 8, etc.

[0230] For example, see Figure 6B, which is a schematic diagram illustrating the duration of a first time period and a sequence length according to an embodiment of the present disclosure. As shown in Figure 6B, the coding rate is 1 / 4, one information bit is mapped to four OOK symbols after Manchester encoding, and the duration of time period d can be the duration of four OOK symbols.

[0231] For example, see Figure 6C, which is a schematic diagram illustrating the duration of a first time period and a sequence length according to an embodiment of the present disclosure. As shown in Figure 6C, the coding rate is 1 / 2, two information bits are mapped to four OOK symbols after Manchester encoding, and the duration of time period d can be the duration of four OOK symbols.

[0232] Method three: The duration of the first time period is the duration of one OFDM symbol or multiple OOK symbols obtained by dividing multiple consecutive OFDM symbols.

[0233] If an OFDM symbol can carry Z OOK symbols, the duration of period d may be the duration of Z OOK symbols. Z may be 2, 4, 8, etc. When Manchester encoding is used, the Z OOK symbols may include Z / 2 OOK ON symbols and Z / 2 OOK OFF symbols.

[0234] For example, see Figure 6D, which is a schematic diagram illustrating the duration of a first time period and a sequence length according to an embodiment of the present disclosure. As shown in Figure 6D, one OFDM symbol can carry four OOK symbols, and the duration of time period d can be the duration of four OOK symbols.

[0235] In some embodiments, the LP WUS in the first time period includes at least two OOK symbols; wherein the at least two OOK symbols carry the first information, and a sequence carried by an OOK ON symbol in the at least two OOK symbols is used to indicate the second information.

[0236] In some possible implementations, determining the first information carried by the LP WUS within a first time period included in the duration of the LP WUS channel includes: determining the first information based on an ON / OFF pattern of the at least two OOK symbols within the first time period.

[0237] For example, as shown in FIG6A , the ON / OFF pattern of the OOK symbol in time period d is (ON, OFF), and it can be determined that the first information is information bit 1, that is, one information bit in the complete information W is 1; the sequence s1 carried by the OOK ON symbol in time period d is used to indicate the second information.

[0238] For example, as shown in FIG6B , the ON / OFF pattern of the OOK symbol in period d is (ON, OFF, ON, OFF), indicating that the first information is information bit 1. Sequences s1 and s2 carried by the OOK ON symbol in period d indicate the second information. Sequences s1 and s2 may be the same or different.

[0239] For example, as shown in FIG6C , the ON / OFF pattern of the OOK symbol in period d is (ON, OFF, OFF, ON), indicating that the first information is information bit 1 and information bit 0. That is, the two information bits in the complete information W are 1 and 0. Sequences s1 and s2 carried by the OOK ON symbol in period d indicate the second information. Sequences s1 and s2 can be the same or different.

[0240] In some possible implementations, the first time period includes multiple OOK ON symbols; a sequence carried by each of the multiple OOK ON symbols is used to indicate a portion of the second information, and the multiple sequences carried by the multiple OOK ON symbols are used to jointly indicate the second information. In this case, determining the second information indicated by the sequence carried by the LP WUS in the first time period includes determining the second information based on the joint indication of the multiple sequences carried by the multiple OOK ON symbols in the first time period.

[0241] For example, as shown in Figure 6B, sequence s1 and sequence s2 may be different, and the second information WA may be divided into two parts and mapped to sequence s1 and sequence s2 respectively; in this case, the terminal may determine the second information WA based on the joint indication of sequence s1 and sequence s2 carried by the two OOK ON symbols within time period d.

[0242] In the above embodiment, since the sequence signal strength that can be detected by LP-WUR on the OOK ON symbol is stronger, the second information indicated by the sequence carried by the OOK ON symbol is beneficial to improving the transmission quality of LP WUR.

[0243] In some possible implementations, the first time period includes multiple OOK ON symbols; a sequence carried by each of the multiple OOK ON symbols is used to indicate the second information. In this case, determining the second information indicated by the sequence carried by the LP WUS in the first time period includes determining the second information based on an indication of any one of multiple sequences carried by the multiple OOK ON symbols in the first time period.

[0244] For example, as shown in FIG6C , sequence s1 and sequence s2 may be the same, and the second information WA may be mapped to sequence s1 and sequence s2 respectively; in this case, the terminal may determine the second information WA based on the indication of sequence s1 or sequence s2 carried by the two OOK ON symbols within time period d.

[0245] In a further embodiment, if the terminal is in a poor channel state, the terminal may not be able to successfully detect sequence s1 to obtain complete information W. In this case, the terminal may perform combined detection on multiple sequences within time period d to determine the second information WA. The combined detection of multiple sequences involved in the present disclosure can also be described as jointly processing the indications of multiple sequences.

[0246] In the above embodiment, since the sequence signal strength that can be detected by the LP-WUR is stronger in the OOK ON symbol, the sequence carried by the OOK ON symbol indicates the second information, which helps improve the transmission quality of the LP WUS. Furthermore, since the sequence carried by each of the multiple OOK ON symbols indicates the second information, the reliability of the LP WUS transmission can be improved by repeatedly transmitting the second information within the first time period.

[0247] In some possible implementations, the sequence carried by the OOK ON symbol in the at least two OOK symbols is a non-zero sequence, and the sequence carried by the OOK OFF symbol in the at least two OOK symbols is an all-zero sequence, where the non-zero sequence and the all-zero sequence are concatenated to obtain a first sequence. In this case, determining the second information indicated by the sequence carried by the LP WUS in the first time period includes determining the first information and the second information based on an indication of the first sequence carried by the at least two OOK symbols in the first time period.

[0248] For example, see Figure 6E, which is a schematic diagram of the duration and sequence length of a first time period according to an embodiment of the present disclosure. As shown in Figure 6E, time period d includes two OOK symbols. When the ON / OFF pattern of the two OOK symbols is (ON, OFF), the first half of the first sequence s10 includes a non-zero subsequence, and the second half of the first sequence includes an all-zero subsequence, that is, a non-zero sequence and an all-zero sequence are cascaded to obtain the first sequence s10; when the ON / OFF pattern of the two OOK symbols is (OFF, ON), the first half of the first sequence s01 includes an all-zero subsequence, and the second half of the first sequence includes a non-zero subsequence, that is, an all-zero sequence and a non-zero sequence are cascaded to obtain the first sequence s01. In this case, based on the indication of the first sequence s10 carried by the two OOK symbols within the time period d, the ON / OFF pattern of the two OOK symbols can be determined to be (ON, OFF), and then the first information can be determined based on the ON / OFF pattern of the two OOK symbols within the time period d, and the second information indicated by the non-zero subsequence included in the first sequence s10 can also be determined.

[0249] In the above embodiment, since the link performance of OFDM LR is better than that of OOK LR, the terminal can obtain complete LP WUS information by detecting the first sequence in the first time period using OFDM LR, which can improve the transmission efficiency of LP WUS and the link performance of LP-WUR.

[0250] In a second aspect, embodiments of the present disclosure provide a signal transmission method. Figure 7 is a schematic flow chart illustrating a signal transmission method according to an embodiment of the present disclosure. The signal transmission method illustrated in this embodiment can be executed by a network device.

[0251] As shown in FIG7 , the signal transmission method may include the following steps:

[0252] In S701, LP WUS information is divided into first information and second information, wherein the LP WUS information is used to determine whether to wake up the MR of the terminal.

[0253] In S702, an LP WUS is sent to the terminal, wherein the LP WUS carries the first information within a first time period included in the duration of the LP WUS channel, and a sequence carried by the LP WUS within the first time period indicates the second information.

[0254] In some embodiments, the terminal may support OOK LR and OFDM LR.

[0255] For example, as shown in FIG5A , D represents the duration of the LP WUS channel, d represents the first time period, where d<D, and W represents complete LP WUS information (referred to as complete information for short). The network device may divide the complete information W into first information A and second information WA. Furthermore, the network device may send an LP WUS to the terminal, wherein the LP WUS carries the first information A using OOK modulation during time period d, and the sequence carried by the LP WUS during time period d indicates the second information WA.

[0256] Optionally, the terminal may receive an LP WUS sent by a network device. In a further embodiment, the terminal may determine first information carried by the LP WUS during the first time period, and second information indicated by a sequence carried by the LP WUS during the first time period, wherein the first information is partial information in the LP WUS information, and the second information is information in the LP WUS information other than the first information. In a further embodiment, the terminal may detect the LP WUS information based on the first and second information and determine whether to wake up the MR of the terminal.

[0257] In some embodiments, the manner of determining the duration of the LP WUS channel may include at least one of the following: a predefined manner; a semi-static configuration; or a dynamic indication.

[0258] In some embodiments, the manner of determining the length of the first time period may include at least one of the following: a predefined manner; a semi-static configuration; or a dynamic indication.

[0259] In some embodiments, the duration of the first period is shorter than the duration of the LP WUS channel. For example, as shown in FIG5A , period D is 8 OOK symbols long, and period d is 2 OOK symbols long.

[0260] In some embodiments, the manner of determining the length of the sequence carried by the LP WUS may include at least one of the following: a predefined manner; a semi-static configuration; or a dynamic indication.

[0261] In some embodiments, the length of the sequence is less than or equal to the length of the first period. For example, as shown in FIG5A , period d is 2 OOK symbols long, indicating that the sequence of the second information WA is 1 OOK symbol long.

[0262] It should be noted that the embodiment shown in FIG. 7 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0263] According to an embodiment of the present disclosure, the base station can divide the complete LP WUS information into first information and second information. The LP WUS directly carries the first information during a first time period, and the sequence carried by the LP WUS during the first time period indicates the second information. Thus, by combining OOK LR and OFDM LR, the terminal can obtain the complete LP WUS information after receiving the OOK symbols of the first time period, without having to wait until all OOK symbols within the duration of the LP WUS channel are received. This improves the transmission efficiency of the LP WUS and can also start waking up the terminal's MR in advance, which is beneficial for improving the detection performance of the LP-WUS. It can also return to the LP-WUS power saving mode in advance, which is beneficial for saving the LP-WUS power consumption.

[0264] In some embodiments, the duration of the LP WUS channel includes the first period and a second period; during the second period, the LP WUS carries third information, wherein the third information is the same as the second information. Optionally, the terminal may determine the third information carried by the LP WUS during the second period.

[0265] For example, see Figure 5B, which is a schematic diagram illustrating an LP WUS carrying wake-up information according to an embodiment of the present disclosure. As shown in Figure 5B, D represents the duration of the LP WUS channel, d represents a first time period, where d < D, and W represents the complete LP WUS information (hereinafter referred to as the complete information). A terminal can receive an LP WUS sent by a network device. The terminal can use OOK LR to determine that the first information carried by the LP WUS in time period d using OOK modulation is A, and can use OFDM LR to determine that the second information indicated by the sequence (overlaid sequence) carried by the LP WUS in time period d is WA. If the channel state of the terminal is poor, the terminal may not be able to obtain the first information and / or the second information after time period d, and thus cannot obtain the complete information W. In this case, the terminal can use OOK LR to determine that the third information carried by the LP WUS in time period Dd using OOK modulation is WA. Furthermore, the terminal can jointly process the OOK symbols and the sequence they carry in time period D to detect the complete information W, and can determine whether to wake up the terminal's MR based on the detected complete information W.

[0266] In some embodiments, the sequence carried by the LP WUS during the second time period indicates fourth information, wherein the fourth information is the LP WUS information. Optionally, the terminal may determine the fourth information indicated by the sequence carried by the LP WUS during the second time period, wherein the fourth information is the LP WUS information; detect the LP WUS information, and determine whether to wake up the MR of the terminal.

[0267] For example, please refer to FIG5C , which is a schematic diagram showing an LP WUS carrying wake-up information according to an embodiment of the present disclosure. As shown in Figure 5C, D represents the duration of the LP WUS channel, d represents the first time period, where d<D, and W represents the complete LP WUS information (referred to as complete information W for short); the terminal can receive the LP WUS sent by the network device, and the terminal can use OOK LR to determine that the first information carried by the LP WUS in the time period d using OOK modulation is A, and can use OFDM LR to determine that the second information indicated by the sequence (overlaid sequence) carried by the LP WUS in the time period d is WA; if the channel state of the terminal is poor, the terminal may not be able to obtain the first information and / or the second information after the time period d, and thus cannot obtain the complete information W, then the terminal can use OOK LR to determine that the third information carried by the LP WUS in the time period Dd using OOK modulation is WA, and can use OFDM LR to determine that the fourth information indicated by the sequence carried by the LP WUS in the time period Dd is W; further, the terminal can jointly process the OOK symbols and the sequence they carry in the time period D to detect the complete information W, and can determine whether to wake up the MR of the terminal based on the detected complete information W.

[0268] In some embodiments, the sequence carried by the LP WUS during the second time period indicates fifth information, wherein the fifth information is the same as the second information. Optionally, the terminal may determine the fifth information indicated by the sequence carried by the LP WUS during the second time period, wherein the fifth information is the same as the second information; detect the LP WUS information, and determine whether to wake up the MR of the terminal.

[0269] For example, please refer to FIG5D , which is a schematic diagram showing an LP WUS carrying wake-up information according to an embodiment of the present disclosure. As shown in Figure 5D, D represents the duration of the LP WUS channel, d represents the first time period, where d<D, and W represents the complete LP WUS information (referred to as complete information W for short); the terminal can receive the LP WUS sent by the network device, and the terminal can use OOK LR to determine that the first information carried by the LP WUS in the time period d using OOK modulation is A, and can use OFDM LR to determine that the second information indicated by the sequence (overlaid sequence) carried by the LP WUS in the time period d is WA; if the channel state of the terminal is poor, the terminal may not be able to obtain the first information and / or the second information after the time period d, and thus cannot obtain the complete information W, then the terminal can use OOK LR to determine that the third information carried by the LP WUS in the time period Dd using OOK modulation is WA, and can use OFDM LR to determine that the fifth information indicated by the sequence carried by the LP WUS in the time period Dd is WA; further, the terminal can jointly process the OOK symbols and the sequence they carry in the time period D to detect the complete information W, and can determine whether to wake up the MR of the terminal based on the detected complete information W.

[0270] In some embodiments, the duration of the LP WUS channel includes multiple first time periods. Optionally, the terminal can detect the LP WUS information based on first information carried by the LP WUS in any first time period and second information indicated by a sequence carried by the LP WUS in any first time period. In some possible implementations, the manner in which the LP WUS information is divided into the first information and the second information varies within the multiple first time periods.

[0271] For example, please refer to FIG5E , which is a schematic diagram showing an LP WUS carrying wake-up information according to an embodiment of the present disclosure. As shown in Figure 5E, D represents the duration of the LP WUS channel, d1, d2, and d3 respectively represent the first time period, where d1=d2=d3<D, and W represents the complete LP WUS information (referred to as complete information for short); the terminal can receive the LP WUS sent by the network device, and the terminal can use OOK LR to determine that the first information carried by the LP WUS in the time period d1, time period d2, and time period d3 using OOK modulation is A, B, and C, respectively, and can use OFDM LR to determine that the second information indicated by the sequence carried by the LP WUS in the time period d1, time period d2, and time period d3 is WA, WB, and WC, respectively; further, after receiving the OOK symbol in time period d, the terminal can detect the complete information W based on the first information A and the second information WA in time period d1, or detect the complete information W based on the first information B and the second information WB in time period d2, or detect the complete information W based on the first information C and the second information WC in time period d3, and determine whether to wake up the MR of the terminal based on the detected complete information W. The first information A, the first information B and the first information C may be the same or different; correspondingly, the second information WA, the second information WB and the second information WC may be the same or different.

[0272] In some embodiments, the duration of the LP WUS channel includes multiple first time periods. Optionally, the terminal may jointly process first information carried by the LP WUS in the multiple first time periods and second information indicated by a sequence carried by the LP WUS in the multiple first time periods to detect the LP WUS information. In some possible implementations, the manner in which the LP WUS information is divided into the first information and the second information in the multiple first time periods is different.

[0273] For example, as shown in Figure 5E, the terminal can receive the LP WUS sent by the network device, and the terminal can use OOK LR to determine that the first information carried by the LP WUS in OOK modulation in time periods d1, d2, and d3 is A, B, and C respectively, and can use OFDM LR to determine that the second information indicated by the sequence carried by the LP WUS in time periods d1, d2, and d3 is WA, WB, and WC respectively; further, if the channel state of the terminal is poor, the terminal may not be able to obtain the complete information W after time period d1, then the terminal can jointly process the OOK symbols in time periods d1 and d2 and the sequences they carry to detect the complete information W; if the complete information still cannot be detected, the terminal can jointly process the OOK symbols in time periods d1, d2, and d3 and the sequences they carry to detect the complete information W.

[0274] It should be noted that the information W, A, WA, B, WB, C, and WC shown in Figures 5A to 5E are only used to represent the division method for LP WUS information. It can be a single information or an information set including multiple information. This disclosure does not specifically limit this.

[0275] In the embodiment shown above, if the channel state of the terminal is poor and the complete LP WUS information is not detected within the first time period, and the LP WUS detection cannot be completed in advance, the terminal can jointly process the OOK symbols and the sequences they carry within the duration of the entire LP WUS channel, thereby improving the reliability of LP WUS transmission and improving the detection performance of LP-WUS.

[0276] In some embodiments, the LP WUS in the first time period includes at least two OOK symbols, and the specific duration of the first time period can be determined by at least one of the following methods:

[0277] Mode 1: The duration of the first time period is the duration of two consecutive OOK symbols, wherein the two consecutive OOK symbols include an OOK ON symbol and an OOK OFF symbol.

[0278] For example, see Figure 6A, which is a schematic diagram illustrating the duration of a first time period and a sequence length according to an embodiment of the present disclosure. As shown in Figure 6A, "1" represents an OOK ON symbol, "0" represents an OOK OFF symbol, and the duration of time period d is the duration of two consecutive OOK symbols.

[0279] Method 2: The duration of the first time period is the duration of multiple OOK symbols mapped to one information bit or multiple information bits after Manchester encoding, where the number of the multiple OOK symbols is equal to the inverse of the coding rate.

[0280] If the coding rate is 1 / X, one or more information bits are mapped to X OOK symbols after Manchester encoding, and the duration of period d can be the duration of X OOK symbols. X can be 2, 4, 8, etc.

[0281] For example, see Figure 6B, which is a schematic diagram illustrating the duration of a first time period and a sequence length according to an embodiment of the present disclosure. As shown in Figure 6B, the coding rate is 1 / 4, one information bit is mapped to four OOK symbols after Manchester encoding, and the duration of time period d can be the duration of four OOK symbols.

[0282] For example, see Figure 6C, which is a schematic diagram illustrating the duration of a first time period and a sequence length according to an embodiment of the present disclosure. As shown in Figure 6C, the coding rate is 1 / 2, two information bits are mapped to four OOK symbols after Manchester encoding, and the duration of time period d can be the duration of four OOK symbols.

[0283] Method three: The duration of the first time period is the duration of one OFDM symbol or multiple OOK symbols obtained by dividing multiple consecutive OFDM symbols.

[0284] If an OFDM symbol can carry Z OOK symbols, the duration of period d may be the duration of Z OOK symbols. Z may be 2, 4, 8, etc. When Manchester encoding is used, the Z OOK symbols may include Z / 2 OOK ON symbols and Z / 2 OOK OFF symbols.

[0285] For example, see Figure 6D, which is a schematic diagram illustrating the duration of a first time period and a sequence length according to an embodiment of the present disclosure. As shown in Figure 6D, one OFDM symbol can carry four OOK symbols, and the duration of time period d can be the duration of four OOK symbols.

[0286] In some embodiments, the LP WUS in the first time period includes at least two OOK symbols; wherein the at least two OOK symbols carry the first information, and a sequence carried by an OOK ON symbol in the at least two OOK symbols is used to indicate the second information.

[0287] In some possible implementations, an ON / OFF pattern of the at least two OOK symbols in the first time period indicates the first information. Optionally, the terminal may determine the first information based on an ON / OFF pattern of the at least two OOK symbols in the first time period.

[0288] For example, as shown in FIG6A , the ON / OFF pattern of the OOK symbol in time period d is (ON, OFF), and it can be determined that the first information is information bit 1, that is, one information bit in the complete information W is 1; the sequence s1 carried by the OOK ON symbol in time period d is used to indicate the second information.

[0289] For example, as shown in FIG6B , the ON / OFF pattern of the OOK symbol in period d is (ON, OFF, ON, OFF), indicating that the first information is information bit 1. Sequences s1 and s2 carried by the OOK ON symbol in period d indicate the second information. Sequences s1 and s2 may be the same or different.

[0290] For example, as shown in FIG6C , the ON / OFF pattern of the OOK symbol in period d is (ON, OFF, OFF, ON), indicating that the first information is information bit 1 and information bit 0, i.e., the two information bits in the complete information W are 1 and 0. Sequences s1 and s2 carried by the OOK ON symbol in period d indicate the second information. Sequences s1 and s2 can be the same or different.

[0291] In some possible implementations, the first time period includes multiple OOK ON symbols; a sequence carried by each of the multiple OOK ON symbols is used to indicate part of the second information, and the multiple sequences carried by the multiple OOK ON symbols are used to jointly indicate the second information. Optionally, the terminal may determine the second information based on the joint indication of the multiple sequences carried by the multiple OOK ON symbols in the first time period.

[0292] For example, as shown in Figure 6B, sequence s1 and sequence s2 may be different, and the second information WA may be divided into two parts and mapped to sequence s1 and sequence s2 respectively; in this case, the terminal may determine the second information WA based on the joint indication of sequence s1 and sequence s2 carried by the two OOK ON symbols within time period d.

[0293] In the above embodiment, since the sequence signal strength that can be detected by LP-WUR on the OOK ON symbol is stronger, the second information indicated by the sequence carried by the OOK ON symbol is beneficial to improving the transmission quality of LP WUR.

[0294] In some possible implementations, the first time period includes multiple OOK ON symbols; a sequence carried by each of the multiple OOK ON symbols is used to indicate the second information. Optionally, the terminal may determine the second information based on an indication of any sequence among multiple sequences carried by the multiple OOK ON symbols in the first time period.

[0295] For example, as shown in FIG6C , sequence s1 and sequence s2 may be the same, and the second information WA may be mapped to sequence s1 and sequence s2 respectively; in this case, the terminal may determine the second information WA based on the indication of sequence s1 or sequence s2 carried by the two OOK ON symbols within time period d.

[0296] In the above embodiment, since the sequence signal strength that can be detected by the LP-WUR is stronger in the OOK ON symbol, the sequence carried by the OOK ON symbol indicates the second information, which helps improve the transmission quality of the LP WUS. Furthermore, since the sequence carried by each of the multiple OOK ON symbols indicates the second information, the reliability of the LP WUS transmission can be improved by repeatedly transmitting the second information within the first time period.

[0297] In some possible implementations, the sequence carried by the OOK ON symbol in the at least two OOK symbols is a non-zero sequence, and the sequence carried by the OOK OFF symbol in the at least two OOK symbols is an all-zero sequence, wherein the non-zero sequence and the all-zero sequence are concatenated to obtain a first sequence, and the first sequence is used to indicate the first information and the second information. Optionally, the terminal can determine the first information and the second information based on the indication of the first sequence carried by the at least two OOK symbols in the first time period.

[0298] For example, see Figure 6E, which is a schematic diagram of the duration and sequence length of a first time period according to an embodiment of the present disclosure. As shown in Figure 6E, time period d includes two OOK symbols. When the ON / OFF pattern of the two OOK symbols is (ON, OFF), the first half of the first sequence s10 includes a non-zero subsequence, and the second half of the first sequence includes an all-zero subsequence, that is, a non-zero sequence and an all-zero sequence are cascaded to obtain the first sequence s10; when the ON / OFF pattern of the two OOK symbols is (OFF, ON), the first half of the first sequence s01 includes an all-zero subsequence, and the second half of the first sequence includes a non-zero subsequence, that is, an all-zero sequence and a non-zero sequence are cascaded to obtain the first sequence s01. In this case, based on the indication of the first sequence s10 carried by the two OOK symbols within the time period d, the ON / OFF pattern of the two OOK symbols can be determined to be (ON, OFF), and then the first information can be determined based on the ON / OFF pattern of the two OOK symbols within the time period d, and the second information indicated by the non-zero subsequence included in the first sequence s10 can also be determined.

[0299] In the above embodiment, since the link performance of OFDM LR is better than that of OOK LR, the terminal can obtain complete LP WUS information by detecting the first sequence in the first time period using OFDM LR, which can improve the transmission efficiency of LP WUS and the link performance of LP-WUR.

[0305] In order to facilitate those skilled in the art to better understand the present disclosure, some exemplary embodiments are provided below in conjunction with the accompanying drawings.

[0306] Example 1:

[0307] In some embodiments, the complete LP WUS information is denoted as W, and the information W may be mapped to OOK symbols and time domain or frequency domain sequences on the OOK symbols in the following manner.

[0308] Method 1: As shown in Figure 5C , OOK symbols in time period d carry information A through OOK modulation, and the time-domain or frequency-domain sequence of OOK symbols in time period d carries information WA. In the rest of the LP WUS, excluding time period d, the OOK symbols carry information WA, and the time-domain or frequency-domain sequence of OOK symbols carries information set W.

[0309] In the above embodiment, the terminal can support early completion of LP WUS detection in time period d, which precedes the entire LP WUS time period D. If the terminal's channel state is poor, the terminal can receive the LP WUS throughout the entire LP WUS time period D, thereby improving detection performance. The terminal can jointly process the OOK symbols and the carried sequence within the entire LP WUS time period D to obtain LP WUS information W.

[0310] Method 2: As shown in Figure 5D , OOK modulation is used to transmit information A to OOK symbols in time period d, and the time or frequency domain sequence of OOK symbols in time period d carries information WA. In the rest of the LP WUS, excluding time period d, the OOK symbols carry information WA, and the time or frequency domain sequence of OOK symbols also carries information WA.

[0311] In the above embodiment, if the terminal's channel state is poor and LP WUS detection is not completed within time period d, the terminal can conveniently combine and receive the sequences carried by the OOK symbols transmitted during the entire LP WUS time period. The terminal can jointly process the OOK symbols and the carried sequences within the entire LP WUS time period D to obtain LP WUS information W.

[0312] Method 3: As shown in Figure 5E , LP WUS period D is divided into multiple sections with time period d as the granularity. These sections sequentially carry information A, information B, information C, ... on OOK symbols using OOK modulation. The time-domain or frequency-domain sequences of the OOK symbols in these sections sequentially carry information WA, information WB, information WC, ...

[0313] In the above embodiment, if the terminal fails to correctly receive the LP WUS based on the first time period d, the terminal may combine and detect the LP WUS based on the first n time periods d to improve link performance, where n>1.

[0314] Example 2:

[0315] In some embodiments, the number of OOK symbols included in time period d is denoted as S. In time period d, the information WA may be mapped to S / 2 OOK symbols. For example, in time period d, when S is equal to 2, one OOK ON symbol carries the information WA; when S is greater than 2, the information WA may be divided into S / 2 parts, each of which is mapped to one OOK ON symbol. In time period d, the OFDM LR may detect the sequence at the timing of each of the S OOK symbols. Generally speaking, the LR may detect a stronger sequence signal strength on an OOK ON symbol. The information WA may be determined based on the sequence detected on the S / 2 OOK ON symbols in time period d.

[0316] As shown in Figure 6A, the code rate of Manchester coding is 1 / 4. Assume that time period d includes 2 OOK symbols, including one OOK ON symbol. One bit of LP WUS information is indicated by the ON / OFF pattern of 4 OOK symbols. For example, bit 1 can be mapped to 4 OOK symbols (ON, OFF, ON, OFF); bit 0 can be mapped to 4 OOK symbols (OFF, ON, OFF, ON). OFDM LR can obtain the one bit of information based on the ON / OFF pattern of the first two OOK symbols. Other information except this one bit is indicated by the sequence S1 carried by the one OOK ON symbol.

[0317] As shown in Figure 6B, the Manchester code rate is 1 / 4. Assume that time period d includes four OOK symbols, including two OOK ON symbols. One bit of LP WUS information is indicated by the ON / OFF pattern of four OOK symbols. Furthermore, the remaining information W', excluding this one bit, is indicated by sequences S1 and S2 carried by two OOK ON symbols. S1 and S2 can be the same, so that each sequence of OOK ON symbols carries the remaining information W'. Alternatively, S1 and S2 can be different. For example, the remaining information W' is divided into two parts and mapped to two OOK ON symbol sequences S1 and S2, respectively.

[0318] As shown in FIG6C , the code rate of Manchester coding is 1 / 2. Assume that time period d includes 4 OOK symbols, including two OOK ON symbols. In time period d, the two bits of LP WUS information are indicated by the ON / OFF pattern of the OOK symbol. In addition, the other information W" other than these two bits is indicated by sequences S1 and S2 carried by two OOK ON symbols. S1 and S2 can be the same, so that each sequence of OOK ON symbols carries the other information W". Alternatively, S1 and S2 can be different, for example, the other information W" is divided into two parts and mapped to sequences S1 and S2 of two OOK ON symbols, respectively.

[0319] In the embodiments shown in FIG6A-FIG6C, the terminal can detect the ON / OFF pattern of the OOK symbol in time period d to obtain the information A carried therein, and detect the information WA carried on the sequence of OOK ON symbols, thereby obtaining the complete LP WUS information W.

[0320] Example 3:

[0321] In some embodiments, when performing sequence-based detection in time period d, the terminal may process the OOK OFF symbol as an all-zero sequence and concatenate it with the sequence of OOK ON symbols to obtain a new sequence for use in time period d. Let the number of OOK symbols in time period d be S. The length of the new sequence is determined by the total duration of K consecutive OOK symbols, where 2 ≤ K ≤ S. For example, K is a factor of S.

[0322] As shown in Figure 6E , taking K equal to 2 as an example, when the two OOK symbols are OOK ON and OOK OFF symbols, the front portion of the new sequence includes a non-zero subsequence, i.e., a sequence of OOK ON symbols, and the other elements are 0. When the two OOK symbols are OOK OFF and OOK ON symbols, the rear portion of the sequence includes a non-zero subsequence, i.e., a sequence of OOK ON symbols, and the other elements are 0. By detecting the new sequence, OFDM LR can simultaneously obtain information A indicated by the OOK symbol ON / OFF pattern and other information WA, thereby obtaining complete LP WUS information W.
