[0089] In some embodiments, to further conserve power, the terminal in power-saving mode can put MR into sleep or ultra-deep sleep mode and enable LP-WUR to listen for LP-WUS. When the terminal's LP-WUR detects LP-WUS targeting this terminal, the terminal can enable MR and perform normal communication transmission. This can greatly reduce the power consumption of MR, and since the power consumption of LP-WUR is very low, a greater power-saving gain can be achieved.

[0090] In some embodiments, in order to properly detect LP-WUS, the terminal needs to obtain the time and frequency location of LP-WUS transmission by the network device. The terminal can obtain time and frequency synchronization by detecting synchronization signals. For example, the synchronization signal can be a multiplexed existing synchronization signal block (SSB), or the synchronization signal can be a low-power synchronization signal (LP-SS). In one embodiment, when the terminal obtains time and frequency synchronization based on SSB and / or LP-SS, LP-WUS can carry wake-up information.

[0091] In some embodiments, LP-WUS may use amplitude shift keying (ASK) modulation to carry wake-up information. In one embodiment, LP-WUS may use OOK modulation to carry wake-up information, where OOK modulation is a special case of ASK modulation.

[0092] In one embodiment, for each OOK symbol, a high level (OOK on chip, OOK ON) represents bit 1, and a low level (OOK off chip, OOK OFF) represents bit 0. In one embodiment, the LP-WUS information can be encoded such that each coded bit is mapped to an OOK symbol, for example, Manchester coding. In one embodiment, 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). It should be noted that this embodiment utilizes the signal amplitude of the OOK signal to carry information.

[0093] In one embodiment, the time-domain or frequency-domain sequence carried by each OOK symbol can also carry wake-up information. In another embodiment, each OOK symbol occupies multiple subcarriers in the frequency domain. Multiple bits of information can be represented on each OOK symbol by carrying different OFDM sequences. For example, if each OOK symbol can carry M information sequences, then the OOK symbol can carry M types of information, corresponding to floor(log₂M) bits. It should be noted that this embodiment utilizes the time-domain or frequency-domain sequence of the OOK signal to carry information.

[0094] In some embodiments, the LP-WUR may include two types of LP-WURs. The first type of LP-WUR only supports envelope detection of the OOK symbols of the LP-WUS, and this type of LP-WUR can be called OOK LR. The link performance of OOK LR is relatively poor. The second type of LP-WUR supports detection of the OFDM time-domain or frequency-domain sequence carried by the OOK symbols of the LP-WUS, thereby improving link performance. This type of LP-WUR can be called OFDM LR.

[0095] In some embodiments, for terminals in the Radio Resource Control (RRC) idle or RRC inactive state, LP-WUS can use codepoints to indicate the subgroup of terminals to be woken up. LP-WUS supports the following two types of codepoints: (1) one codepoint corresponds to one terminal group; (2) one codepoint corresponds to all terminal groups. Furthermore, the time-domain or frequency-domain sequence on LP-WUS must carry all the information of LP-WUS. The OFDM LR can obtain all the LP-WUS information from the OFDM time-domain or frequency-domain sequence. In some embodiments, for RRC connected terminals, both codepoints and bitmaps are candidate methods for indicating wake-up information in LP-WUS; which method to use has not yet been determined.

[0096] In some embodiments, the ZC sequence can be used as an OFDM sequence carried on an OOK symbol. The length of the ZC sequence is related to the number of resource blocks (RBs) in the LP-WUS signal. In one embodiment, the number of RBs in LP-WUS can be 11 RBs, containing 132 subcarriers. The length of the ZC sequence corresponding to LP-WUS can be 131. Due to the relatively long length of the ZC sequence, the detection performance of the ZC sequence can be guaranteed. In one embodiment, there can be a maximum of 4 candidate ZC sequences on an OOK symbol, so an OOK symbol can represent 2 bits of information, as shown in Table 1.

[0097] Table 1

[0098] In some embodiments, for the method of transmitting LP-WUS related information using code points, assuming the total number of terminal groups is N, the required number of code point sequences is at least N+1. Assuming the length of the code point sequence is L bits, to ensure good correlation between any two code point sequences, generally 2... LIt must be much greater than N+1, otherwise it will be impossible to find a sufficient number (greater than or equal to N+1) of sequences with good correlation properties.

[0099] In some embodiments, for the method of transmitting LP-WUS related information using a bitmap, assuming the total number of terminal groups is N, the required number of bits in the bitmap is N, with each bit corresponding to one terminal group. However, transmitting only these N bits in an OOK-modulated signal is insufficient, as the miss detection rate (MDR) or false alarm rate (FAR) will not meet the requirements. Generally, an M-bit cyclic redundancy check (CRC) can be added to this N-bit bitmap, or forward error correction (FEC) or Reed-Muller (RM) channel coding can be applied to these N bits, resulting in N' bits (N' is generally significantly larger than N, for example, N' = 2*N). This ensures MDR or FAR when transmitting information bits after CRC verification or other channel coding in an OOK-modulated signal.

[0100] Therefore, it can be seen that LP-WUS carries a large number of bits, which can easily affect transmission efficiency, reliability, and / or complexity. Based on this, how to carry wake-up information in OFDM-based LP-WUS signals in order to minimize the number of bits while ensuring detection performance is a question that needs to be discussed.

[0101] Figure 2A is an interactive schematic diagram of a communication method according to an exemplary embodiment. As shown in Figure 2A, this disclosure relates to a communication method for a communication system 100, the method including steps S2101 to S2102.

[0102] In step S2101, the network device sends the first type of LP-WUS to the terminal.

[0103] In some embodiments, the terminal receives a first type of LP-WUS sent by a network device. In one embodiment, the terminal can detect the first type of LP-WUS sent by the network device based on a first transceiver. In one embodiment, when the terminal's second transceiver is in a sleep state, the terminal can detect the first type of LP-WUS sent by the network device based on the first transceiver.

[0104] In some embodiments, the terminal may have a first transceiver and a second transceiver. In one embodiment, the power consumption of the first transceiver in its operating state is less than that of the second transceiver in its operating state. In one embodiment, the capability of the first transceiver is weaker than that of the second transceiver. In one embodiment, the first transceiver may be an LP-WUR transceiver, and the second transceiver may be a MR transceiver.

[0105] In one embodiment, LP-WUS may include a first type of LP-WUS and a second type of LP-WUS, wherein the first type of LP-WUS carries information in a different way than the second type of LP-WUS.

[0106] In some embodiments, the first type of LP-WUS may include at least one first modulation symbol, which may be used to carry a first sequence, the first sequence including first information. In one embodiment, the first sequence may be superimposed on each of the at least one first modulation symbol, and based on this, the first sequence may be referred to as an overlaid sequence.

[0107] In some embodiments, the modulation scheme corresponding to the first modulation symbol is different from the modulation scheme corresponding to the first sequence. In some embodiments, the modulation scheme corresponding to the first modulation symbol may be ASK modulation. In one embodiment, the modulation scheme corresponding to the first modulation symbol may be OOK modulation, that is, the first modulation symbol may be an OOK symbol. In some embodiments, the modulation scheme corresponding to the first sequence may be OFDM modulation. In one embodiment, the first sequence may be an OFDM time-domain sequence. In one embodiment, the first sequence may be an OFDM frequency-domain sequence. In one embodiment, the first type of LP-WUS may utilize an OFDM sequence to carry first information. In one embodiment, the first type of LP-WUS may be an OFDM-based LP-WUS.

[0108] In some embodiments, the first sequence may be a fixed sequence, which may carry fixed information content. In one embodiment, the first sequence may include a ZC sequence. In one embodiment, the fixed information content carried by the ZC sequence may be as shown in Table 1.

[0109] In some embodiments, the first information can be used to indicate a first terminal group to be woken up. In one embodiment, the first terminal group may include at least one terminal. In one embodiment, the network device may be pre-configured with multiple first terminal groups, each of which may include at least one terminal. In one embodiment, the network device may use the first information carried in a first sequence within a first type of LP-WUS to indicate the first terminal group to be woken up, thereby triggering at least one terminal in the first terminal group to wake up to wake up a second transceiver for communication transmission.

[0110] In one embodiment, the name of the first information is not limited; for example, it may be wake-up information or wake-up instruction information.

[0111] In some embodiments, the first information may include a first bit diagram. In some embodiments, the first bit diagram may be used to indicate whether a plurality of first terminal groups need to be woken up.

[0112] In some embodiments, the first bit diagram may include multiple bits, each bit corresponding to a first terminal group. In one embodiment, the number of bits in the first bit diagram is determined based on the total number of first terminal groups. In one embodiment, the total number of first terminal groups is N, then the number of bits in the first bit diagram is N, and each bit in the first bit diagram corresponds to a first terminal group.

[0113] In some embodiments, different bit values ​​of each bit in the first bit diagram are used to indicate whether the first terminal group corresponding to the bit needs to be woken up. In one embodiment, when the bit value of a bit in the first bit diagram is a first value (e.g., 1), the first bit diagram is used to indicate that the first terminal group corresponding to that bit needs to be woken up. In one embodiment, when the bit value of a bit in the first bit diagram is a second value (e.g., 0), the first bit diagram is used to indicate that the first terminal group corresponding to that bit does not need to be woken up.

[0114] In some embodiments, the network device can determine the first bit map carried in the first sequence within the first type of LP-WUS based on the first terminal group to be woken up. In one embodiment, if the network device needs to wake up a first terminal group, the network device can send the first type of LP-WUS, where the bit value of the bit corresponding to the first terminal group in the first bit map of the first type of LP-WUS is a first value, and the bit values ​​of the other bits in the first bit map are second values. In one embodiment, if the network device needs to wake up all first terminal groups, the network device can send the first type of LP-WUS, where the bit values ​​of all bits in the first bit map of the first type of LP-WUS are the first values.

[0115] In one embodiment, the first information is carried by a first sequence in a first type of LP-WUS. Since the detection reliability of the first sequence is sufficient to meet the requirements, the first sequence in the first type of LP-WUS can directly carry the first bit map without channel coding, without carrying redundant bits.

[0116] In some embodiments, the second type of LP-WUS may include at least one first modulation symbol, which can be used to carry second information. In some embodiments, the modulation scheme corresponding to the first modulation symbol may be ASK modulation. In one embodiment, the modulation scheme corresponding to the first modulation symbol may be OOK modulation, that is, the first modulation symbol may be an OOK symbol. In one embodiment, the second type of LP-WUS may carry second information based on the signal amplitude of the OOK symbol. In one embodiment, the second type of LP-WUS may be an OOK-based LP-WUS.

[0117] In some embodiments, the second information can be used to indicate a first terminal group to be woken up. In one embodiment, the first terminal group may include at least one terminal. In one embodiment, the network device may be pre-configured with multiple first terminal groups, each of which may include at least one terminal. In one embodiment, the network device may use the second information carried by at least one first modulation symbol in a second type of LP-WUS to indicate the first terminal group to be woken up, thereby triggering at least one terminal in the first terminal group to wake up to wake up a second transceiver for communication transmission.

[0118] In one embodiment, the name of the second information is not limited; for example, it may be wake-up information or wake-up instruction information.

[0119] In some embodiments, the number of bits of the second information can be greater than the number of bits of the first information. In one embodiment, the second information is carried by the signal amplitude in a second type of LP-WUS. In order for the detection performance of the second type of LP-WUS to meet the requirements, the second information carried by the second type of LP-WUS includes not only information bits but also redundant bits. In this case, the number of bits of the second information carried by the second type of LP-WUS will be significantly greater than the number of bits of the first information carried by the first type of LP-WUS.

[0120] In some embodiments, the second information may be obtained by channel coding based on the first information. In one embodiment, the first information carried by the first sequence in the first type of LP-WUS may be information that has not been channel coded, and the second information carried by at least one first modulation symbol in the second type of LP-WUS may be information after channel coding. In one embodiment, the first bit map may be 8 bits. The first sequence in the first type of LP-WUS sent by the network device may carry the first bit map without channel coding, that is, the first sequence in the first type of LP-WUS carries 8 bits of information, while at least one first modulation symbol in the second type of LP-WUS sent by the network device may carry information after channel coding based on the first bit map, that is, at least one first modulation symbol in the second type of LP-WUS carries 16 bits of information. The 16 bits may be an 8-bit bit map + 8-bit CRC, or it may be the encoded bits obtained after the 8-bit bit map has undergone channel coding such as FEC.

[0121] In some embodiments, the terminal may send capability information to the network device, which may be used to indicate that the terminal supports a first capability or a second capability. In one embodiment, if the terminal supports the first capability, the terminal's first transceiver supports detection of a first type of LP-WUS. In one embodiment, if the terminal supports the first capability, the terminal's first transceiver may be an OFDM LR. In one embodiment, if the terminal supports the second capability, the terminal's first transceiver supports detection of a second type of LP-WUS. In one embodiment, if the terminal supports the second capability, the terminal's first transceiver may be an OOK LR.

[0122] In one embodiment, the capability information is further used by the network device to determine whether to send a first type of LP-WUS. In one embodiment, the capability information indicates that the terminal supports a first capability, and the network device determines to send the first type of LP-WUS. In one embodiment, the capability information indicates that the terminal supports a second capability, and the network device determines not to send the first type of LP-WUS; in this case, the network device may send the second type of LP-WUS.

[0123] In step S2102, the terminal wakes up the second transceiver according to the first type of LP-WUS.

[0124] In some embodiments, after the terminal detects the first type of LP-WUS based on the first transceiver, the terminal can determine whether to wake up the second transceiver based on the first type of LP-WUS.

[0125] In one embodiment, if the first bit diagram carried in the first sequence within the first type of LP-WUS indicates that the first terminal group to be woken up includes a terminal, the terminal wakes up the second transceiver.

[0126] In one embodiment, if the first terminal group to be woken up indicated by the first bit diagram carried in the first sequence within the first type of LP-WUS does not include a terminal, the terminal may not wake up the second transceiver, and step S2102 may be omitted.

[0127] In some embodiments, the term "information" may be used interchangeably with terms such as "message," "signal," "signaling," "report," "configuration," "indication," "instruction," "command," "channel," "parameter," "field," and "data."

[0128] In some embodiments, the term "send" may be used interchangeably with terms such as "transmit," "report," or "transmit."

[0129] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2102. For example, step S2101 may be implemented as a standalone embodiment, but is not limited thereto.

[0130] In some embodiments, step S2102 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0131] Figure 2B is a schematic diagram of an interaction of a communication method according to an exemplary embodiment. As shown in Figure 2B, the present disclosure relates to a communication method for a communication system 100, the method including steps S2201 to S2202.

[0132] In step S2201, the network device sends the first type of LP-WUS to the terminal.

[0133] In some embodiments, the terminal receives a first type of LP-WUS sent by a network device. In one embodiment, the terminal can detect the first type of LP-WUS sent by the network device based on a first transceiver. In one embodiment, when the terminal's second transceiver is in a sleep state, the terminal can detect the first type of LP-WUS sent by the network device based on the first transceiver.

[0134] In some embodiments, the terminal may have a first transceiver and a second transceiver. In one embodiment, the power consumption of the first transceiver in its operating state is less than that of the second transceiver in its operating state. In one embodiment, the capability of the first transceiver is weaker than that of the second transceiver. In one embodiment, the first transceiver may be an LP-WUR transceiver, and the second transceiver may be a MR transceiver.

[0135] In one embodiment, LP-WUS may include a first type of LP-WUS and a second type of LP-WUS, wherein the first type of LP-WUS carries information in a different way than the second type of LP-WUS.

[0136] In some embodiments, the first type of LP-WUS may include at least one first modulation symbol, which may be used to carry a first sequence, the first sequence including first information. In one embodiment, the first sequence may be superimposed on each of the at least one first modulation symbol, and based on this, the first sequence may be referred to as an overlaid sequence.

[0137] In some embodiments, the modulation scheme corresponding to the first modulation symbol is different from the modulation scheme corresponding to the first sequence. In some embodiments, the modulation scheme corresponding to the first modulation symbol may be ASK modulation. In one embodiment, the modulation scheme corresponding to the first modulation symbol may be OOK modulation, that is, the first modulation symbol may be an OOK symbol. In some embodiments, the modulation scheme corresponding to the first sequence may be OFDM modulation. In one embodiment, the first sequence may be an OFDM time-domain sequence. In one embodiment, the first sequence may be an OFDM frequency-domain sequence. In one embodiment, the first type of LP-WUS may utilize an OFDM sequence to carry first information. In one embodiment, the first type of LP-WUS may be an OFDM-based LP-WUS.

[0138] In some embodiments, the first sequence may be a fixed sequence, which may carry fixed information content. In one embodiment, the first sequence may include a ZC sequence. In one embodiment, the fixed information content carried by the ZC sequence may be as shown in Table 1.

[0139] In some embodiments, the first information can be used to indicate a first terminal group to be woken up. In one embodiment, the first terminal group may include at least one terminal. In one embodiment, the network device may be pre-configured with multiple first terminal groups, each of which may include at least one terminal. In one embodiment, the network device may use the first information carried in a first sequence within a first type of LP-WUS to indicate the first terminal group to be woken up, thereby triggering at least one terminal in the first terminal group to wake up to wake up a second transceiver for communication transmission.

[0140] In one embodiment, the name of the first information is not limited; for example, it may be wake-up information or wake-up instruction information.

[0141] In some embodiments, the first information may include a first index, which indicates a first code point. In one embodiment, the first code point corresponds to a first terminal group to be woken up.

[0142] In some embodiments, the first information is associated with a first set. In one embodiment, the first set may include multiple code points and corresponding indices for the code points. In one embodiment, the first set may be used to indicate the mapping relationship between the multiple code points and the multiple indices. In one embodiment, the presentation format of the first set is not specifically limited; for example, the first set may be in the form of a table.

[0143] In some embodiments, the number of multiple code points within the first set can be determined based on the total number of first terminal groups. In one embodiment, if the total number of first terminal groups is N, then the number of multiple code points within the first set is N+1. In one embodiment, the multiple code points within the first set may include N first-type code points and 1 second-type code point, wherein any one of the N first-type code points corresponds to one first terminal group, and the second-type code point corresponds to multiple first terminal groups.

[0144] In one embodiment, to ensure good correlation between any two code points within the first set, the length of the code point needs to be much greater than the number of bits required to indicate multiple first terminal groups. In one embodiment, assuming the total number of first terminal groups is N, the number of bits required to indicate multiple first terminal groups is floor(log2(N+1)). Assuming the length of the code point is L, L should be much greater than floor(log2(N+1)). In one example, assuming N = 32, indicating multiple first terminal groups only requires 6 bits. However, to ensure a sufficient number (>=33) of code points with good correlation characteristics can be found, the code point length can be 12 bits. In this case, to reduce the number of bits carried by the first type of LP-WUS, the index corresponding to the code point can be carried by the first sequence within the first type of LP-WUS. Thus, only 6 bits are needed to indicate the code points corresponding to multiple first terminal groups within the first set.

[0145] In one embodiment, the first information is carried by the first sequence in the first type of LP-WUS. Since the detection reliability of the first sequence is sufficient to meet the requirements, the first sequence in the first type of LP-WUS can directly carry the first index corresponding to the first code point, instead of carrying the first code point itself.

[0146] In some embodiments, the first set can be used by the network device to determine a first index based on a first code point corresponding to a first terminal group to be woken up. In one embodiment, the network device can determine the first index corresponding to the first code point based on the first terminal group to be woken up, the first code point corresponding to the first terminal group to be woken up, and the first set, thereby carrying the first index in a first sequence within a first type of LP-WUS, so as to wake up the first terminal group using the first type of LP-WUS.

[0147] In one embodiment, if the network device needs to wake up a first terminal group, the network device can determine the first code point (i.e., the first type of code point) corresponding to the first terminal group and the first index corresponding to the first code point. The network device can send a first type of LP-WUS, and the first sequence within the first type of LP-WUS can carry the first index corresponding to the first code point. In another embodiment, if the network device needs to wake up all first terminal groups, the network device can determine the first code point (i.e., the second type of code point) and the first index corresponding to the first code point. The network device can send a first type of LP-WUS, and the first sequence within the first type of LP-WUS can carry the first index corresponding to the first code point.

[0148] In some embodiments, the second type of LP-WUS may include at least one first modulation symbol, which can be used to carry second information. In some embodiments, the modulation scheme corresponding to the first modulation symbol may be ASK modulation. In one embodiment, the modulation scheme corresponding to the first modulation symbol may be OOK modulation, that is, the first modulation symbol may be an OOK symbol. In one embodiment, the second type of LP-WUS may carry second information based on the signal amplitude of the OOK symbol. In one embodiment, the second type of LP-WUS may be an OOK-based LP-WUS.

[0149] In some embodiments, the second information can be used to indicate a first terminal group to be woken up. In one embodiment, the first terminal group may include at least one terminal. In one embodiment, the network device may be pre-configured with multiple first terminal groups, each of which may include at least one terminal. In one embodiment, the network device may use the second information carried by at least one first modulation symbol in a second type of LP-WUS to indicate the first terminal group to be woken up, thereby triggering at least one terminal in the first terminal group to wake up to wake up a second transceiver for communication transmission.

[0150] In one embodiment, the name of the second information is not limited; for example, it may be wake-up information or wake-up instruction information.

[0151] In some embodiments, the number of bits of the second information can be greater than the number of bits of the first information. In one embodiment, the second information is carried by the signal amplitude in a second type of LP-WUS. In order for the detection performance of the second type of LP-WUS to meet the requirements, the second information carried by the second type of LP-WUS includes not only information bits but also redundant bits. In this case, the number of bits of the second information carried by the second type of LP-WUS will be significantly greater than the number of bits of the first information carried by the first type of LP-WUS.

[0152] In some embodiments, the second information may include a first code point. In one embodiment, the first information carried by the first sequence within the first type of LP-WUS may be a first index corresponding to the first code point, and the second information carried by at least one first modulation symbol within the second type of LP-WUS may be the first code point. In one embodiment, assuming the code point length may be 12 bits and the number of multiple code points included in the first set may be 33, then the multiple indices included in the first set may be 0-32 respectively. In this case, the first sequence within the first type of LP-WUS sent by the network device may carry the first index corresponding to the first code point, that is, the first sequence within the first type of LP-WUS carries 6 bits of information, while at least one first modulation symbol within the second type of LP-WUS sent by the network device may carry the first code point, that is, at least one first modulation symbol within the second type of LP-WUS carries 12 bits of information.

[0153] In some embodiments, the terminal may send capability information to the network device, which may be used to indicate that the terminal supports a first capability or a second capability. In one embodiment, if the terminal supports the first capability, the terminal's first transceiver supports detection of a first type of LP-WUS. In one embodiment, if the terminal supports the first capability, the terminal's first transceiver may be an OFDM LR. In one embodiment, if the terminal supports the second capability, the terminal's first transceiver supports detection of a second type of LP-WUS. In one embodiment, if the terminal supports the second capability, the terminal's first transceiver may be an OOK LR.

[0154] In one embodiment, the capability information is further used by the network device to determine whether to send a first type of LP-WUS. In one embodiment, the capability information indicates that the terminal supports a first capability, and the network device determines to send the first type of LP-WUS. In one embodiment, the capability information indicates that the terminal supports a second capability, and the network device determines not to send the first type of LP-WUS; in this case, the network device may send the second type of LP-WUS.

[0155] In step S2202, the terminal wakes up the second transceiver according to the first type of LP-WUS.

[0156] In some embodiments, after the terminal detects the first type of LP-WUS based on the first transceiver, the terminal can determine whether to wake up the second transceiver based on the first type of LP-WUS.

[0157] In some embodiments, the terminal may determine the first code point indicated by the first index within the first type of LP-WUS based on the first set. In one embodiment, the first set can be found in the description of the first set in step S2201, which will not be repeated here. In some embodiments, the first set may be used by the terminal to determine the first code point indicated by the first index.

[0158] In one embodiment, the first code point can be used by the terminal to determine the first terminal group to be woken up. In one embodiment, after detecting the first type of LP-WUS, the terminal can obtain the first index carried in the first sequence based on the first type of LP-WUS, and determine the first code point indicated by the first index based on the first set, thereby determining the first terminal group based on the first code point. The first terminal group is the first terminal group to be woken up by the first type of LP-WUS.

[0159] In one embodiment, if the first terminal group corresponding to the first code point indicated by the first index in the first type of LP-WUS includes a terminal, the terminal wakes up the second transceiver.

[0160] In one embodiment, if the first terminal group corresponding to the first code point indicated by the first index in the first type of LP-WUS does not include a terminal, the terminal may not wake up the second transceiver, and step S2202 may be omitted.

[0161] In some embodiments, the term "information" may be used interchangeably with terms such as "message," "signal," "signaling," "report," "configuration," "indication," "instruction," "command," "channel," "parameter," "field," and "data."

[0162] In some embodiments, the term "send" may be used interchangeably with terms such as "transmit," "report," or "transmit."

[0163] The communication method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2202. For example, step S2201 may be implemented as a standalone embodiment, but is not limited thereto.

[0164] In some embodiments, step S2202 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0165] Figure 3 is an interactive schematic diagram of a communication method according to an exemplary embodiment. As shown in Figure 3, the embodiments of this disclosure relate to an information processing method, which includes step S3101.

[0166] In step S3101, the network device sends LP-WUS to the terminal.

[0167] In some embodiments, the network device sends a first type of LP-WUS to the terminal.

[0168] In some embodiments, the terminal receives LP-WUS sent by the network device. In one embodiment, the terminal receives a first type of LP-WUS sent by the network device.

[0169] In some embodiments, the first type LP-WUS includes at least one first modulation symbol for carrying a first sequence. In one embodiment, the first sequence includes first information for indicating a first terminal group to be woken up.

[0170] In some embodiments, the first information includes a first bit diagram, which indicates a first terminal group to be woken up, the first terminal group including at least one terminal.

[0171] In some embodiments, the first information includes a first index, which indicates a first code point, and the first code point corresponds to a first terminal group to be woken up.

[0172] In some embodiments, LP-WUS further includes a second type of LP-WUS, which includes at least one first modulation symbol for carrying second information for indicating a first terminal group to be woken up, and the number of bits of the second information is greater than the number of bits of the first information.

[0173] In some embodiments, where the first information includes a first bit map, the second information may be obtained after channel coding based on the first information. In one embodiment, the first information may be a first bit map before channel coding, and the second information may be obtained after channel coding based on the first bit map.

[0174] In some embodiments, where the first information includes a first index, the second information may be a first code point.

[0175] In some embodiments, the first modulation symbol is an on / off keyed OOK symbol, and the first sequence is an orthogonal frequency division multiplexing (OFDM) sequence.

[0176] In some embodiments, the OFDM sequence includes one of the following: an OFDM frequency domain sequence; or an OFDM time domain sequence.

[0177] To better understand the embodiments of this disclosure, the following exemplary embodiments will be used to further illustrate this disclosure.

[0178] In some embodiments, for the method of using code points to carry wake-up information of LP-WUS, the index of the code point sequence to be transmitted can be carried in the OFDM sequence carried by the OOK symbol, without carrying the code point sequence itself. In contrast, the code point sequence itself is carried in the OOK-based LP-WUS signal.

[0179] In some embodiments, for the method of using a bitmap to carry wake-up information for LP-WUS, the wake-up information without channel coding can be carried in the OFDM sequence carried by the OOK symbol. Correspondingly, the bits after channel coding of the bitmap can be carried in the LP-WUS signal based on the OOK symbol.

[0180] In some embodiments, for the method of using code points to carry LP-WUS wake-up information, assuming the total number of terminal groups is N, the required number of code point sequences is at least N+1. Assuming the length of the code point sequence is L bits, theoretically, to ensure good correlation between any two code point sequences, it is generally required that 2... L The number of sequences with good correlation properties must be much greater than N+1; otherwise, it will be impossible to find a sufficient number (greater than or equal to N+1). In one embodiment, N = 32, then only 6 bits are needed to represent 32+1 kinds of information (2^32 + 1^32). ^5 <33<=2 ^6 However, the length of the code point sequence needs to be much greater than 6 to ensure that a sufficient number (>=33) of sequences with good correlation properties can be found. In one embodiment, L=10 or L=12.

[0181] In one embodiment, 33 code point sequences can be selected from a 0-1 sequence of length L = 12 by using the principle of high autocorrelation and low cross-correlation. Each code point sequence is 12 bits long. Each of the 32 code point sequences corresponds to a terminal group, and another code point sequence corresponds to all terminal groups.

[0182] In one embodiment, for an OOK-based LP-WUS signal, if a network device needs to wake up a certain terminal group, it needs to transmit the code point sequence corresponding to that terminal group. If the network device needs to wake up all terminal groups, it needs to transmit the code point sequence corresponding to all terminal groups. That is, the network device needs to transmit a 12-bit OOK modulated signal. After Manchester encoding, the 12 bits will be mapped onto 24 OOK symbols for transmission, which will occupy the duration of 24 OOK symbols in the time domain.

[0183] In one embodiment, for OFDM-based LP-WUS signals, since the LP WUS information is carried by ZC sequences, and the detection reliability of the ZC sequences is sufficient, redundant bits are not required in OFDM-based LP-WUS. In another embodiment, the OFDM-based LP-WUS signal only needs to carry the index of the code point sequence to be transmitted. For example, if there are a total of 33 code point sequences numbered 0-32, only 6 bits are needed to indicate all the wake-up information.

[0184] In one example, the OFDM-based LP WUS signal carrying the aforementioned 6 bits of information is as follows. For example, the 11th code point sequence to be indicated (i.e., terminal group 11) has the bit information 001011. Assuming sequences 1-4 correspond to 00, 01, 10, and 11 respectively, then it needs to be carried on 3 OOK symbols, and the ZC sequences on these 3 OOK symbols are S1(00), S3(10), and S4(11).

[0185] In some embodiments, for the method of using a bitmap to carry LP-WUS wake-up information, assuming the total number of terminal groups is N, the required number of bits in the bitmap is N, with each bit corresponding to one terminal group. However, transmitting only these N bits in an OOK-modulated signal is insufficient, as its MDR or FAR will not meet the requirements. Generally, an M-bit CRC can be added to the bitmap of these N bits, or channel coding such as FEC or RM can be performed on these N bits, resulting in N' bits (N' is generally significantly larger than N, for example, N' = 2*N). In this way, when transmitting information bits that have undergone CRC verification or other channel coding in an OOK-modulated signal, MDR or FAR can be guaranteed.

[0186] In one embodiment, if a network device needs to wake up a specific terminal group, it needs to transmit a bitmap in which the bit values ​​corresponding to that terminal group are set to 1. If the network device needs to wake up multiple terminal groups, it needs to transmit a bitmap in which the bit values ​​corresponding to all of those terminal groups are set to 1. If the network device needs to wake up all terminal groups, it needs to transmit a bitmap in which all bits are set to 1. For example, the bitmap may consist of 8 bits. Channel coding, such as adding 8 bits of CRC or performing FEC or RM coding, increases the bitmap from 8 bits to 16 bits.

[0187] In one embodiment, for an OOK-based LP-WUS signal, the network device needs to transmit a 16-bit OOK modulated signal after channel coding. After Manchester coding, the 16 bits will be mapped onto 32 OOK symbols for transmission, which will occupy the duration of 32 OOK symbols in the time domain.

[0188] In one embodiment, for OFDM-based LP-WUS signals, since the LP WUS information is carried by the ZC sequence, and the detection reliability of the ZC sequence is sufficient, redundant bits are not required in OFDM-based LP-WUS. In one embodiment, only the 8 bits of information before the channel coding to be transmitted need to be carried in the OFDM-based LP-WUS signal, without carrying the 16 bits of information after the channel coding.

[0189] In one example, a specific example of an OFDM-based LP WUS signal carrying the aforementioned 8 bits of information is as follows. For example, if the bitmap to be indicated is 01000001, and assuming that sequences 1-4 correspond to 00, 01, 10, and 11 respectively, then it needs to be carried on 4 OOK symbols. The ZC sequences on these 4 OOK symbols are S2(01), S1(00), S1(00), and S2(01).

[0190] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods.

All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), tensor processing unit (TPU), deep learning processing unit (DPU), etc.
