[0039] In a first aspect, an embodiment of the present disclosure provides a communication method, which is performed by a network device. The method includes:

[0040] Sending a first signal, wherein the first signal is used to achieve time-frequency synchronization of receiving a second signal, and / or the first signal is used to determine a transmission position of a third signal; wherein the second signal is used for at least one of the following: waking up a main radio MR of the terminal, not waking up the MR, or changing a sleep state of the MR; and the third signal is used for time-frequency synchronization between the terminal and the network device; and

[0041] The first signal does not carry any information, or the first signal carries part or all of the first information; the first information is related information of at least one of the first signal, the second signal, and the third signal.

[0042] In the above embodiment, when the network device sends the first signal, it may use the first signal to carry or not carry information, wherein, when the first signal carries information, the information it carries may be the first information, and the first information may be: related information of at least one of the first signal, the second signal, and the third signal. It can be seen from this that the embodiment of the present disclosure defines a method for determining whether the first signal specifically carries information, and clarifies the transmission mechanism of the first signal. In addition, the embodiment of the present disclosure also defines what information the first signal specifically carries when it carries information, thereby ensuring that the first signal can successfully carry the corresponding information. Therefore, after the receiving end of the first signal (such as a terminal) receives the first signal, in addition to being able to implement the functions implemented by the first signal itself based on the first signal, it can also perform other communication operations based on the information carried in the first signal, thereby improving communication flexibility and communication efficiency.

[0043] In conjunction with some embodiments of the first aspect, in some embodiments, the first information includes at least one of the following:

[0044] Second information, where the second information is time-frequency synchronization information corresponding to the second signal;

[0045] third information, where the third information is used to indicate at least one cell; the cells indicated by the third information include at least one first cell and / or at least one second cell, where the first cell is a cell covered by the first signal or the second signal, and the second cell is a neighboring cell of the first cell;

The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0251] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile Communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0252] Optionally, the aforementioned LP WUS can be sent by the network device to the terminal and can be received by the low power wake up receiver (LP-WUR) of the terminal. LP WUS can be used to instruct the terminal to wake up the main radio (MR) so that the terminal can use the MR to process downlink and / or uplink data normally, or LP WUS can be used to instruct the terminal not to wake up the MR or change the sleep state of the MR, such as switching between any of the states such as Ultra-deep sleep, Deep Sleep, Light Sleep, Micro sleep, etc., so as to achieve the purpose of saving power. Optionally, LP WUS may be used for terminals in Radio Resource Control (RRC) connected, inactive, idle, etc. states. Optionally, there are two working modes of LP WUR, one is always ON and the other is duty cycle. For always ON mode, the LP WUR of the terminal is always in the on state, and the network device can send LP WUS at any time. In duty cycle mode, the terminal only opens the LP WUR during the LP WUS listening time window according to a certain mechanism, and the network device can only send the LP WUS during this time period.

[0253] Optionally, in some embodiments, taking into account the time-frequency deviation during the operation of the LP WUR, a synchronization signal is introduced to achieve time-frequency synchronization of the terminal for the LP WUS reception. The synchronization signal may be a reused existing primary synchronization signal (PSS) and / or secondary synchronization signal (SSS), or the synchronization signal may be a low power synchronization signal (LP SS). Optionally, when the synchronization signal is an LP SS, the LP SS may usually carry some information so that the terminal can not only implement the functions of the LP SS itself based on the LP SS (i.e., implement time-frequency synchronization of the LP WUS reception), but also perform some other communication operations based on the information carried by the LP SS, thereby improving communication efficiency and communication flexibility. However, the specific method used by the LP SS to carry information has not yet been clearly defined.

[0254] Optionally, in some embodiments, the modulation method of the LP SS is generally a modulation method based on orthogonal frequency division multiplexing on-off keying (OFDM-OOK). Among them, the LP SS after OFDM-OOK modulation may include OOK modulation symbols and OFDM sequences (such as OFDM time domain sequences and / or OFDM frequency domain sequences). In addition, when the LP SS is modulated by OFDM-OOK modulation, the way in which the LP SS carries information may include the following two: in one implementation, the information may be carried by the OOK modulation symbols of the LP SS; in another implementation, the information may be carried by the OOK modulation symbols of the LP SS and the OFDM sequence. Based on the above two implementations, there may be the following multiple possibilities for the design of the OOK modulation symbols and OFDM sequences of the LP SS.

[0255] Optional Example 1: The OOK modulation symbol of the LP SS corresponds to a fixed OOK pattern. The OOK modulation symbol does not carry information, and only the OFDM sequence carries information.

[0256] Optional Example 2: The OFDM sequence of the LP SS is a fixed sequence. The OFDM sequence does not carry information, and only OOK modulation symbols carry information.

[0257] Optional Example 3: Both the OFDM sequence and OOK modulation symbols of the LP SS carry information;

[0258] Optional example 4: Neither the OFDM sequence nor the OOK modulation symbol of the LP SS carries any information.

[0259] Optionally, the above-mentioned OOK modulation symbols can be detected and received by the terminal's On-Off Keying low power wake up receive (OOK LR), and the above-mentioned OFDM sequence can be detected and received by the terminal's Orthogonal Frequency Division Multiplexing low power wake up receive (OFDM LR). In addition, since in actual network deployment, there are both terminals that support OFDM WUR and terminals that support OOK WUR, considering the ability to fully cover all terminal users and more efficiently transmit information, it is necessary to design the above-mentioned OOK modulation symbols and / or OFDM sequences of LP SS so that they can carry information. However, at present, there is no clear definition of how the OOK modulation symbols and / or OFDM sequences of LP SS are specifically designed to carry information.

[0260] Furthermore, there is no clear definition of what information the LP SS should carry.

[0261] FIG2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0262] Step 2101: The network device sends a first signal.

[0263] Optionally, the network device may send the first signal to the terminal, and the terminal may receive the first signal.

[0264] Optionally, in some embodiments, the network device may send the first signal based on a first configuration. The first configuration may, for example, be used to configure the transmission location of the first signal. The first configuration may be agreed upon by a protocol, or the first configuration may be autonomously determined by the network device. When the first configuration is autonomously determined by the network device, the network device further indicates the first configuration to the terminal. Furthermore, the terminal may receive the first signal based on the first configuration. Specifically, the terminal may first determine the first configuration based on the protocol agreement and / or the indication of the network device, and then receive the first signal based on the first configuration.

[0265] Furthermore, in some embodiments, the first signal can be used to achieve time-frequency synchronization of the reception of the second signal, and / or, the first signal can be used to determine the transmission position of the third signal; wherein, the second signal can be used for at least one of the following: waking up the MR of the terminal, not waking up the MR, changing the sleep state of the MR; the third signal can be used for time-frequency synchronization between the terminal and the network device.

[0266] The relationship between the first signal, the second signal, and the third signal is described in detail below.

[0267] Optionally, the network device typically needs to send a second signal to the terminal to wake up the terminal's MR, or not wake up the terminal's MR, or change the MR's sleep state. Optionally, the aforementioned "waking up the terminal's MR" can be understood, for example, as switching the terminal's MR from a sleep state to an awake state. When the MR is in the awake state, the terminal can use the MR to normally process downlink and / or uplink data; when the terminal does not need to process downlink and / or uplink data, the MR can switch to a sleep state to save power. Optionally, the aforementioned "not waking up the MR" can be understood, for example, as switching the MR from an awake state to a sleep state, or allowing the MR to remain in the sleep state, thereby saving power. Optionally, the aforementioned MR sleep state can include at least one of the following: ultra-deep sleep, deep sleep, light sleep, or micro sleep. The aforementioned "changing the MR's sleep state" can be understood, for example, as switching between any of ultra-deep sleep, deep sleep, light sleep, or micro sleep. The terminal consumes different amounts of power when maintaining different sleep states. Therefore, the network device may send a second signal to the terminal to instruct the terminal to change the sleep state of the MR for the purpose of saving power of the terminal.

[0268] Optionally, the first signal may be used to achieve time-frequency synchronization for receiving the second signal. This time-frequency synchronization may include, for example, at least one of the following: time domain synchronization, frequency domain synchronization, or time domain and frequency domain synchronization. The specific implementation of time-frequency synchronization for receiving the second signal using the first signal will be described later.

[0269] Optionally, in some embodiments, the first signal may be, for example, LP SS, and the second signal may be, for example, LP WUS, but is not limited thereto. Optionally, the terminal mentioned in the embodiments of the present disclosure may be a terminal supporting LP WUS.

[0270] Optionally, the third signal can be used for time and frequency synchronization between the terminal and the network device. For example, when the terminal initially accesses the network, it is usually necessary to receive a third signal to achieve time and frequency synchronization between the terminal and the network device. The third signal can be, for example, at least one of a synchronization signal block (SSB), a PSS, and an SSS.

[0271] Furthermore, in some embodiments, the first signal may not carry any information, or may carry part or all of the first information; wherein the first information may be related information of at least one of the first signal, the second signal, and the third signal. For example, the first information may be referred to as LP WUS assistance information or LP SS information. Optionally, the first information may include at least one of the following:

[0272] The second information may be time-frequency synchronization information corresponding to the second signal; wherein the time-frequency synchronization information may be used to achieve time-frequency synchronization of receiving the second signal.

[0273] third information, where the third information may be used to indicate at least one cell. For example, the third information may include a cell identity (cell ID) of at least one cell. The cells indicated by the third information may include at least one first cell and / or at least one second cell. The first cell may be a cell covered by the first signal or the second signal, and the second cell may be a neighboring cell of the first cell.

[0274] Fourth information, the fourth information may be used to indicate at least one cell group. For example, the fourth information may include at least one area ID. The at least one cell group indicated by the fourth information may be a cell group located in an area identified by the area ID. The cell group may include at least one cell. For example, the cell group may include the first cell and / or the second cell. Furthermore, the cell group may further include other cells in addition to the first cell and the second cell.

[0275] First interval information, which may be used to indicate a time interval between the first signal and at least one of the third signal and the second signal. Optionally, the time interval may be, for example, an absolute time unit and / or a relative time unit. The absolute time unit may be, for example, hours, minutes, seconds, milliseconds, etc.; the relative time unit may be, for example, a radio frame, a radio subframe, a symbol, a time slot, etc.

[0276] Second interval information, the second interval information can be used to indicate the frequency domain interval between the first signal and at least one of the third signal, the second signal, and point A; wherein Point A can be a common reference point as a resource block grid; usually the lowest (smallest) subcarrier (SCS#0) of the common resource block CRB#0 relative to all subcarrier intervals is called Point A, for example: "Point A" can be located at subcarrier position 0 of common resource block 0 (CRB 0). Optionally, the frequency domain interval can be, for example, an absolute frequency domain unit and / or a relative frequency domain unit, wherein the absolute frequency domain unit can be, for example, Hertz (Hz), kilohertz (KHz), megahertz (MHz), gigahertz (GHz), etc., and the relative frequency domain unit can be, for example, a resource block (RB), a resource element (RE), etc.

[0277] fifth information, the fifth information may include part or all of the information to be carried by the second signal; optionally, the information to be carried by the second signal may be, for example, information for waking up the MR of the terminal, or information for not waking up the MR of the terminal, or information for changing the sleep state of the MR;

[0278] The repetition information may be used to indicate the number of repetitions of the first information and / or the fifth information.

[0279] Optionally, in some embodiments, the third information and the fourth information mentioned above may not be carried by the first signal, but may be implicitly indicated by the first signal. Optionally, the method of implicitly indicating the third information and the fourth information by the first signal may include, for example: pre-setting the correspondence between different cells or different cell groups and different transmission resources (such as time domain resources and / or frequency domain resources). At the same time, the network device may determine the target cell or target cell group that it needs to indicate to the terminal, and implicitly indicate the target cell or target cell group to the terminal by sending a first signal on the transmission resource corresponding to the target cell or target cell group. After the terminal receives the first signal, it can determine the target cell or target cell group implicitly indicated by the network device based on the transmission resource of the first signal and the above-mentioned correspondence, thereby realizing the implicit indication of the third information and the fourth information mentioned above, and there is no need for the first signal to carry the third information and / or the fourth information, which saves communication resources to a certain extent.

[0280] It should be noted that, in some embodiments, the relationship between the first information carried by the above-mentioned first signal and the information to be carried by the second signal may be: assuming that the full set of the first information carried by the first signal is Q, and the full set of information to be carried by the second signal is W, then the intersection of W and Q may be empty; or, the intersection of W and Q may not be empty; or, Q may be a subset of W; or, Q may be the full set of W, that is, Q and W are equal; or, W and Q may also be other relationships, which are not specifically limited in this disclosure.

[0281] And, in some embodiments, the modulation mode corresponding to the first signal may be a modulation mode based on orthogonal frequency division multiplexing on-off keying (OFDM-OOK), wherein when the first signal is modulated using OFDM-OOK, the first signal may include at least one of at least one first modulation symbol and a first sequence; and the modulation mode corresponding to the first modulation symbol is different from the modulation mode corresponding to the first sequence; for example, the modulation mode corresponding to the first modulation symbol may be OOK, and the modulation mode corresponding to the first sequence may be OFDM. And, the first modulation symbol may be an OOK modulation symbol, and the first sequence may include an OFDM time domain sequence and / or an OFDM frequency domain sequence. Further, when the first signal is modulated using OFDM-OOK, at least one first modulation symbol of the first signal and the first sequence of the first signal may be superimposed together, and the first sequence may also be referred to as an overlapping sequence or an overlaid sequence.

[0282] Optionally, at least one first modulation symbol of the above-mentioned first signal can be detected and received by the on-off keying low power wake up receiver (On-Off Keying low power wake up receive, OOK LR) of the terminal, and the first sequence of the above-mentioned first signal can be detected and received by the orthogonal frequency division multiplexing low power wake up receiver (Orthogonal Frequency Division Multiplexing low power wake up receive, OFDM LR) of the terminal.

[0289] Sixth pattern feature: the last M OOK modulation symbols of the first signal are ON symbols, where M is an integer, M≥1.

[0290] Optionally, in some embodiments, when the modulation mode corresponding to the first signal is OFDM-OOK, the first modulation symbol of the first signal may not carry information, or at least one first modulation symbol of the first signal may carry part or all of the above-mentioned first information; and, the first sequence of the first signal may not carry information, or the first sequence of the first signal may carry part or all of the above-mentioned first information; and, the information content carried by at least one first modulation symbol may be the same as or different from the information content carried by the first sequence.

[0291] Optionally, the method of carrying information by at least one first modulation symbol and / or first sequence may include at least one of the following:

[0292] Optional Example 1: In some embodiments, at least one first modulation symbol of the first signal may correspond to a fixed pattern. For example, the pattern characteristics of the fixed pattern corresponding to the at least one first modulation symbol of the first signal may be the first pattern characteristics, the second pattern characteristics, the third pattern characteristics, the fourth pattern characteristics, the fifth pattern characteristics, or the sixth pattern characteristics described above. Furthermore, the fixed pattern may not carry any information, or may carry fixed information content. For example, the fixed pattern may fixedly carry the second information and the third information in the first information described above.

[0293] Optional Example 2: In other embodiments, the pattern corresponding to at least one first modulation symbol of the first signal may be randomly determined, that is, the pattern characteristics corresponding to the patterns of the first signal sent by the network device at different times are random. For example, the pattern characteristics corresponding to the pattern of the first signal sent by the network device at the first time may be the first pattern characteristics described above, and the pattern characteristics corresponding to the pattern of the first signal sent by the network device at the second time may be the second pattern characteristics described above. Furthermore, when the pattern corresponding to at least one first modulation symbol of the first signal is randomly determined, the first modulation symbol may not carry any information.

[0294] Optional Example Three: In some further embodiments, at least one first modulation symbol corresponding to the first time period of the first signal may carry part or all of the content of the first information, and / or, the first sequence corresponding to the first time period of the first signal may carry part or all of the content of the first information.

Furthermore, the fixed information content may, for example, be the second information and the third information in the aforementioned first information.

[0296] It should be noted that, in some embodiments, at least one of the “fixed pattern, first time period, and fixed sequence” mentioned above may be predefined by the network device based on a protocol.

[0297] Based on the above, the specific carrying method of at least one first modulation symbol and the first sequence of the first signal is described in detail below. The carrying method of at least one first modulation symbol and the first sequence may include at least one of the following:

[0298] Method 1: In some embodiments, at least one first modulation symbol within a first time period of a first signal may carry the first content of the first information, and a first sequence within the first time period of the first signal may carry the second content of the first information; at least one first modulation symbol within a second time period of the first signal may carry the second content of the first information, and a first sequence within the second time period of the first signal may carry the entire content of the first information; wherein the first time period and the second time period together constitute the total transmission time period of the first signal, and the first content and the second content together constitute the entire content of the first information. For example, FIG2B is a schematic diagram of a method for carrying at least one first modulation symbol and a first sequence of a first signal according to an embodiment of the present disclosure. As shown in FIG2B , the first time period may be the first d time period of the total transmission time period of the first signal, the second time period may be the time period of the total transmission time period of the first signal excluding the first time period, the first content may be a portion of the first information, for example, the first content may be named "A" in FIG2B , and the second content may be the entire content of the first information excluding the first content, for example, when the full set of information of the first information is Q, the second content may be QA. In addition, at least one first modulation symbol within the first time period of the first signal can carry the first content "A", the first sequence within the first time period of the first signal can carry the second content "QA", at least one first modulation symbol within the second time period of the first signal can carry the second content "QA", and the first sequence within the second time period of the first signal can carry the entire content "Q" of the first information.

[0299] Optionally, when the first signal uses method 1 above to carry the first information, after receiving the first signal, the terminal can complete the detection of all the content carried by the first signal in advance by detecting the content of the first time period preceding the first signal, thereby improving communication efficiency. Furthermore, if the terminal is in a poor channel state, the terminal can also detect and receive the first signal within the total transmission period of the first signal, similarly completing the detection of all the content carried by the first signal, thereby improving the terminal's detection performance for the first signal.

[0300] Method 2: In some embodiments, at least one first modulation symbol in the first time period of the first signal can carry the first content of the first information, and the first sequence in the first time period of the first signal can carry the second content of the first information; at least one first modulation symbol in the second time period of the first signal can carry the second content of the first information, and the first sequence in the second time period of the first signal can carry the second content of the first information. For example, FIG2C is a schematic diagram of the carrying method of at least one first modulation symbol and the first sequence of the first signal according to an embodiment of the present disclosure. As shown in FIG2C, at least one first modulation symbol in the first time period of the first signal can carry the first content "A", the first sequence in the first time period of the first signal can carry the second content "QA", at least one first modulation symbol in the second time period of the first signal can carry the second content "QA", and the first sequence in the second time period of the first signal can carry the second content "QA".

[0301] Optionally, when the first signal uses the above-mentioned method 2 to carry the first information, it is relatively convenient to combine and receive at least one first modulation symbol and the first sequence within the total transmission period of the first signal to detect all the content carried by the first signal.

[0302] Method 3: In some embodiments, the total transmission period of the first signal is divided into at least one sub-period, wherein the information content carried by at least one first modulation symbol in the same sub-period of the first signal and the information content carried by the first sequence in the same sub-period together constitute the entire content of the first information, and the information content carried by the first modulation symbols in different sub-periods does not overlap, and the information content carried by the first sequences in different sub-periods does not overlap. For example, Figure 2D is a schematic diagram of a method for carrying at least one first modulation symbol and a first sequence of the first signal according to an embodiment of the present disclosure. As shown in Figure 2D, the total transmission period of the first signal is divided into at least one sub-period, wherein at least one first modulation symbol in the first sub-period can carry first content "A", the first sequence in the first sub-period can carry second content "QA", at least one first modulation symbol in the second sub-period can carry third content "B", the first sequence in the second sub-period can carry fourth content "QB", at least one first modulation symbol in the third sub-period can carry fifth content "C", and the first sequence in the second sub-period can carry sixth content "QC". Among them, the first content "A", the third content "B", and the fifth content "C" do not overlap, and the first content "A" and the second content "QA" together constitute the entire content of the first information, the third content "B" and the fourth content "QB" together constitute the entire content of the first information, and the fifth content "C" and the sixth content "QC" together constitute the entire content of the first information.

[0303] Optionally, when the first signal carries the first information using the third method described above, the terminal can complete detection of all content carried by the first signal in each sub-time period of the first signal, thereby improving the terminal's flexibility in detecting the first signal. Furthermore, if the terminal fails to correctly receive the first signal in the first sub-time period, the terminal can combine detection of the first signal based on the first H sub-time periods, thereby improving link performance, where H>1 and H is a positive integer.

[0304] Method 4: In some embodiments, at least one first modulation symbol in the first time period of the first signal can carry the first content of the first information, at least one first modulation symbol in the second time period of the first signal can carry the second content of the first information, and the first sequence in the first time period of the first signal can carry the entire content of the first information. For example, FIG2E is a schematic diagram of the carrying method of at least one first modulation symbol and the first sequence of the first signal according to an embodiment of the present disclosure. As shown in FIG2E, at least one first modulation symbol in the first time period of the first signal can carry the first content "A", at least one first modulation symbol in the second time period of the first signal can carry the second content "QA", and the first sequence in the first time period of the first signal can carry the entire content "Q" of the first information. It should be noted that, in this method four, the carrying method of the first sequence in the second time period of the first signal is not limited. Optionally, the first sequence in the second time period may carry information or may not carry information. When the first sequence in the second time period carries information, it may carry part or all of the content in the first information. When the first sequence in the second time period carries part of the content in the first information, the information it carries may be the first content "A" or not the first content "A", or may be the second content "QA" or not the second content "QA". This disclosure does not make specific limitations here.

[0305] Optionally, when the first signal uses the above-mentioned method four to carry the first information, after the terminal receives the first signal, it can support the early completion of the detection of all the content carried by the first signal by detecting the content of the first time period before the first signal, thereby improving communication efficiency.

[0306] Method 5: In some embodiments, the first modulation symbol does not carry information, and the first sequence carries the entire content of the first information. For example, Figure 2F is a schematic diagram illustrating at least one first modulation symbol and a first sequence carrying manner of a first signal according to an embodiment of the present disclosure. As shown in Figure 2F, the first modulation symbol of the first signal does not carry information, and the first sequence of the first signal can carry the entire content "Q" of the first information.

[0307] Method 6: In some embodiments, the first modulation symbol does not carry information, and the first sequence within the first time period of the first signal carries the entire content of the first information. For example, Figure 2G is a schematic diagram illustrating a method for carrying at least one first modulation symbol and first sequence of a first signal according to an embodiment of the present disclosure. As shown in Figure 2G, the first modulation symbol of the first signal does not carry information, and the first sequence within the first time period of the first signal carries the entire content "Q" of the first information. It should be noted that in this method 6, the method for carrying the first sequence within the second time period of the first signal is not limited. Optionally, the first sequence within the second time period may or may not carry information. When the first sequence within the second time period carries information, it may carry part or all of the content of the first information. Furthermore, when the first sequence within the second time period carries part of the content of the first information, the information carried may be the first content "A" or not, or may be the second content "QA" or not. This disclosure does not make specific limitations here.

[0308] Method 7: In some embodiments, the first modulation symbol does not carry information, the first sequence in the third time period of the first signal carries the second information in the first information, and the first sequence in the fourth time period of the first signal carries the entire content of the first information; wherein, the third time period and the fourth time period are both subsets of the total transmission time period of the first signal, and the third time period does not overlap with the fourth time period. And, optionally, the third time period can be the first s time period of the total transmission time period of the first signal, or the third time period can be the last s time period of the total transmission time period of the first signal, or the third time period can be the middle s time period of the total transmission time period of the first signal. The fourth time period can be before or after the third time period, and the present disclosure does not specifically limit this. For example, FIG2H is a schematic diagram illustrating a method for carrying at least one first modulation symbol and a first sequence of a first signal according to an embodiment of the present disclosure. As shown in FIG2H , the third time period is the first time period of duration s before the total transmission time period of the first signal, and the fourth time period is the time period of duration d after the third time period. Furthermore, the first modulation symbol of the first signal does not carry any information. The first sequence within the third time period of the first signal carries the second information within the first information, and the first sequence within the fourth time period of the first signal carries the entire content "Q" of the first information. It should be noted that in this seventh method, the method for carrying the first sequence within time periods other than the third and fourth time periods within the total transmission time period of the first signal is not limited. Optionally, the first sequence within such time period may or may not carry information. When the first sequence within such time period carries information, it may carry part or all of the content of the first information. Furthermore, when the first sequence within such time period carries part of the content of the first information, the information carried may be the first content "A" or not, or may be the second content "QA" or not. This disclosure does not specifically limit this.

[0309] Method 8: In some embodiments, the first modulation symbol does not carry information, and the first sequence in the third time period of the first signal carries the second information in the first information; the remaining time period in the total transmission time period of the first signal excluding the third time period is divided into at least one sub-time period, and the first sequence in the sub-time period of the first signal carries the entire content of the first information. For example, Figure 2I is a schematic diagram of at least one first modulation symbol and first sequence carrying method of the first signal according to an embodiment of the present disclosure. As shown in Figure 2I, the first modulation symbol of the first signal does not carry information, and the third time period is the first s time period of the total transmission time period of the first signal, the first sequence in the third time period of the first signal carries the second information in the first information, and the remaining time period in the total transmission time period of the first signal excluding the third time period is divided into at least one sub-time period, wherein the first sequence in each sub-time period carries the entire content "Q" of the first information.

[0310] Method 9: In some embodiments, at least one first modulation symbol carries the entire content of the first information, and the first sequence carries no information. Optionally, the aforementioned method of "at least one first modulation symbol carries the entire content of the first information" may include at least one of the following: at least one first modulation symbol within the first time period of the first signal carries the entire content of the first information, or at least one first modulation symbol within the total transmission time period of the first signal carries the entire content of the first information, or other methods may also be used, which are not specifically limited in this disclosure.

[0311] Method 10: In some embodiments, neither the first modulation symbol nor the first sequence carries any information.

[0312] Step 2102: The network device configures at least one of “fixed pattern, first time period, fixed sequence” to the terminal.

[0313] In some embodiments, the network device may semi-statically configure at least one of "fixed pattern, first time period, fixed sequence" to the terminal, or the network device may dynamically configure at least one of "fixed pattern, first time period, fixed sequence" to the terminal.

[0314] Optionally, the network device configures at least one of the "fixed pattern, first time period, fixed sequence" to the terminal so that the terminal can know at least one of the "fixed pattern, first time period, fixed sequence" based on the configuration of the network device, and then the terminal can determine the information content carried by the first signal based on at least one of the "fixed pattern, first time period, fixed sequence", and perform other communication operations based on the information content, thereby improving communication efficiency and communication flexibility.

[0315] Step 2103: The terminal determines at least one of “fixed pattern, first time period, fixed sequence”.

[0316] Optionally, the terminal may determine at least one of the "fixed pattern, first time period, and fixed sequence" based on a protocol pre-definition. Alternatively, the terminal may determine at least one of the "fixed pattern, first time period, and fixed sequence" based on a configuration of a network device (such as a semi-static configuration and / or a dynamic configuration).

[0317] Step 2104: The network device determines a transmission position of the second signal and / or the third signal based on the first interval information and / or the second interval information and sends the second signal and / or the third signal at the transmission position of the second signal and / or the third signal.

[0318] Optionally, the transmission position may include a time domain position and / or a frequency domain position. Furthermore, the network device may determine the time domain position of the second signal and / or the third signal based on the time domain position of the first signal and the first interval information, and determine the frequency domain position of the second signal and / or the third signal based on the frequency domain position of the first signal and the second interval information. Thereafter, the second signal may be sent at the transmission position of the second signal (i.e., the time domain position and / or frequency domain position of the second signal), and the third signal may be sent at the transmission position of the third signal (i.e., the time domain position and / or frequency domain position of the third signal).

[0319] Step 2105: The terminal determines a transmission location of the second signal and / or the third signal based on the received first information to receive the second signal and / or the third signal.

[0320] Optionally, after receiving the first signal, the terminal may determine the time domain position of the second signal and / or the third signal based on the first interval information carried by the first signal, and determine the frequency domain position of the second signal and / or the third signal based on the second interval information carried by the first signal. Specifically, in some embodiments, after receiving the first signal, the terminal may know the actual transmission position of the first signal. Thereafter, the terminal may determine the time interval between the second signal and the third signal and the first signal respectively based on the above-mentioned first interval information, and determine the time domain position of the second signal and the third signal based on the time interval and the time domain position of the first signal. Similarly, the terminal may determine the frequency domain interval between the second signal and the third signal and the first signal respectively based on the above-mentioned second interval information, and determine the frequency domain position of the second signal and the third signal based on the frequency domain interval and the frequency domain position of the first signal. Thereafter, the terminal may directly receive the second signal and the third signal at the time domain position and frequency domain position of the second signal and the third signal, thereby eliminating the need to receive the second signal and the third signal through blind detection, thereby reducing the time of terminal blind detection and improving communication efficiency.

[0321] For example, taking the third signal as SSB as an example, in one embodiment, when the first interval information carried by the first signal is: the time interval between the first signal and the SSB, if a terminal using OFDM LR newly enters the cell coverage and receives the first signal, the terminal can obtain the time domain position of the MR searching for the SSB according to the first interval information carried by the first signal, and if the terminal is subsequently paged in this cell, the MR of the terminal can directly go to the corresponding time domain position to find the SSB or control resource set (coreset) 0 after being awakened, thereby reducing the terminal blind detection time and improving communication efficiency.

[0322] In another embodiment, when the second interval information carried by the first signal is the frequency domain interval between the first signal and the SSB, if a terminal using OFDM LR newly enters the cell coverage area and receives the first signal, the terminal can obtain the frequency domain position of the MR to search for the SSB based on the second interval information carried by the first signal. Furthermore, if the terminal is subsequently paged in the cell, the MR of the terminal can directly search for the SSB or coreset0 at the corresponding frequency domain position after being awakened, thereby reducing the terminal's blind detection time and improving communication efficiency.

[0323] In the above embodiment, when the network device sends the first signal, it may use the first signal to carry or not carry information, wherein, when the first signal carries information, the information it carries may be the first information, and the first information may be: related information of at least one of the first signal, the second signal, and the third signal. It can be seen from this that the embodiment of the present disclosure defines a method for determining whether the first signal specifically carries information, and clarifies the transmission mechanism of the first signal. In addition, the embodiment of the present disclosure also defines what information the first signal specifically carries when it carries information, thereby ensuring that the first signal can successfully carry the corresponding information. Therefore, after the receiving end of the first signal (such as a terminal) receives the first signal, in addition to being able to implement the functions implemented by the first signal itself based on the first signal, it can also perform other communication operations based on the information carried in the first signal, thereby improving communication flexibility and communication efficiency.

[0324] The communication method according to the embodiments of the present disclosure may include at least one of steps 2101 to 2105. For example, step 2101 may be implemented as an independent embodiment, step 2102 may be implemented as an independent embodiment, step 2103 may be implemented as an independent embodiment, and step 2101+step 2102 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0325] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0418] In some embodiments, the above method may include the method described in the above embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.

For example, step 5101 may be implemented as an independent embodiment, and step 5102 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0420] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0421] The following is an exemplary introduction to the above method.

[0422] Optional embodiment:

[0423] In a network, a base station can wake up LP WUS-supported terminals in a cell or change their sleep state by sending an LP WUS. For LP WUS-supported terminals, the base station receives at least one LP WUS signal via an LP WUR and completes MR wakeup or sleep state change based on the information carried in the received LP WUS signal. MR sleep state change refers to switching between super deep sleep, deep sleep, light sleep, and shallow sleep, and MR wakeup refers to the MR transitioning from any sleep state to an awake state. Before receiving an LP WUS, the UE's LP WUR attempts to receive an LP SS to obtain LP WUS auxiliary information, or LP SS information, such as time-frequency synchronization information, cell ID information, area ID information, time interval information, frequency domain interval information, repetition information, partial LP WUS wakeup information, and full LP WUS wakeup information, without limitation. The base station transmits the LP SS according to a protocol-defined configuration or a configuration indicated by the base station to at least one UE, and the UE monitors the LP SS according to the protocol-defined configuration or base station configuration.

[0424] The base station transmits an LP SS to at least one UE, where the LP SS information is mapped to OOK symbols and / or a time domain or frequency domain sequence on the OOK symbols. The scheme for the base station to transmit the LP SS to the at least one UE includes at least one of the following:

[0425] Optional Example 1:

[0426] The base station determines a fixed OOK pattern and sends an LP SS to at least one UE. The fixed OOK pattern carries fixed information or no information. The fixed OOK pattern is predefined by a protocol, semi-statically configured by the base station to the at least one UE, or dynamically configured by the base station to the at least one UE.

[0427] Optional Example 2:

[0428] The base station determines a random OOK pattern and sends an LP SS to at least one UE, where the random OOK pattern does not carry any information.

[0429] Optional Example 3:

[0430] The base station determines to send an LPSS of duration d to at least one UE. The duration d is predefined by a protocol, semi-statically configured by the base station to the at least one UE, or dynamically configured by the base station to the at least one UE. The duration d is a subset of the LPSS duration D.

[0431] Optional Example 4:

[0432] The base station determines a fixed frequency domain or time domain sequence to transmit an LPSS to at least one UE. The fixed frequency domain or time domain sequence carries fixed information or no information. The fixed frequency domain or time domain sequence is predefined by a protocol, semi-statically configured to the at least one UE by the base station, or dynamically configured to the at least one UE by the base station. Furthermore, the fixed frequency domain or time domain sequence includes at least one of a ZC sequence, an m-sequence, and a gold sequence. Other sequences are not excluded.

[0433] Furthermore, the OOK pattern is the time domain arrangement of ON symbols and OFF symbols in the LP WUS duration. The OOK pattern specifically includes at least one of the following forms:

[0434] The LP SS duration contains only ON symbols;

[0435] The LP SS duration is divided into ON symbols and OFF symbols, and the number of ON symbols is equal to the number of OFF symbols;

[0436] The LP SS duration is divided into ON symbols and OFF symbols, and the number of ON symbols and OFF symbols is not equal;

[0437] The duration d of LP SS duration is all ON symbols;

[0438] The first N symbols in the LP SS duration are ON symbols, N ≥ 1;

[0439] The last M symbols in the LP SS duration are ON symbols, M ≥ 1.

[0440] Another optional embodiment:

[0441] In a network, a base station can wake up terminals in a cell that support LP WUS or change the sleep state of these terminals by sending an LP WUS. For terminals that support LP WUS, at least one LP WUS signal is received via an LP WUR, and the MR wakes up or changes its sleep state based on the information carried by the received LP WUS signal. The change in the MR's sleep state refers to switching between states such as super deep sleep, deep sleep, light sleep, and shallow sleep, and the MR wakes up when the MR transitions from any sleep state to an awake state. Before receiving the LP WUS, the UE's LP WUR attempts to receive an LP SS to obtain auxiliary information for the LP WUS, such as time-frequency synchronization information, cell ID information, area ID information, time interval information, repetition information, partial wake-up information for the LP WUS, full wake-up information for the LP WUS, etc., without limitation. The base station sends the LP SS according to a protocol-defined configuration or a configuration indicated by the base station to at least one UE, and the UE monitors the LP SS according to the protocol-predefined configuration or the base station configuration.

[0442] The LPSS carries information in at least one of the following ways: carrying all auxiliary information through OOK modulation; carrying all auxiliary information through a time / frequency domain sequence carried by the LPSS symbol; or carrying part of the auxiliary information through OOK modulation and part of the auxiliary information through a time / frequency domain sequence carried by the LPSS symbol. The auxiliary information carried by the sequence and the auxiliary information carried by the OOK modulation can be the same or different.

[0443] The LP WUS information set is W, and the LP WUS auxiliary information / LP SS information set is Q. The relationship between W and Q includes at least one of the following: the intersection of W and Q is empty; the intersection of W and Q is not empty; Q is a subset of W; Q is the complete set of W. Furthermore, the information contained in Q includes at least one of the following: time-frequency synchronization information, cell ID information, area ID information, time interval information, frequency domain interval information, repetition information, LP WUS partial wake-up information, and LP WUS full wake-up information.

[0444] The time-frequency synchronization information is used by the UE to complete time-frequency synchronization.

[0445] The cell ID information includes at least one cell ID, or related information of at least one cell ID.

[0446] The area ID information includes a group of cell ID information or related information of a group of cell ID information.

The measurement unit includes an absolute time unit and / or a relative time unit.

[0448] The frequency domain interval information includes at least one of the frequency domain interval information between LP SS and SSB, the frequency domain interval information between LP SS and PSS, the frequency domain interval information between LP SS and SSS, the frequency domain interval information between LP SS and LP WUS, and the frequency domain interval information between LP SS and point A, and is used to indicate the frequency domain interval between the two, and the measurement unit includes an absolute frequency domain unit and / or a relative frequency domain unit.

[0449] The repetition information includes at least one of the number of repetitions of the LP WUS auxiliary information / LP SS information and the number of repetitions of the LP WUS wake-up information.

[0450] The wake-up information of the LP WUS refers to the wake-up information carried by the LP WUS.

[0451] The scheme for mapping the LP WUS auxiliary information / LP SS information to the OOK symbol and / or the time domain or frequency domain sequence on the OOK symbol includes at least one of the following:

[0452] Optional Example 1:

[0453] The OOK modulation of the LPSS in time period d carries information A, and the time or frequency domain sequence of OOK symbols in time period d carries information QA. In the rest of the LPSS, excluding time period d, OOK modulation carries information QA, and the time or frequency domain sequence of OOK symbols carries information set Q. Figure 2B illustrates this method. Using this method, time period d preceding the LPSS supports early completion of LPSS detection. If the UE's channel conditions are poor, the UE can receive the LPSS throughout the entire LPSS time period D, thereby improving detection performance.

[0454] Optional Example 2:

[0455] The OOK modulation of the LPSS within time period d carries information A, and the time or frequency domain sequence of OOK symbols within time period d carries information QA. In the rest of the LPSS, excluding time period d, the OOK modulation carries information QA, and the time or frequency domain sequence of OOK symbols carries information set QA. Figure 2C illustrates this method. This method facilitates combined reception of the sequence of OOK symbols transmitted within the entire LPSS time period.

[0456] Optional Example 3:

[0457] The LPSS is divided into multiple segments, with time segments d as the granularity. The OOK symbols of the LPSS segments sequentially carry information sets A, B, C, ...; and the time-domain or frequency-domain sequences of the OOK symbols of the corresponding segments sequentially carry information sets QA, QB, QC, .... Figure 2D illustrates this method. Using this method, if the UE fails to correctly receive the LPSS based on the first time segment d, the UE can combine and detect the LPSS based on the first n time segments d, where n > 1, thereby improving link performance.

[0458] Optional Example 4:

[0459] The OOK modulation of the LPSS in time period d carries information A, and the time domain or frequency domain sequence of OOK symbols in time period d carries information Q. In the rest of the LPSS except time period d, OOK modulation carries information QA.

[0460] 2E is a schematic diagram of this method. Using this method, the time period d before the LP SS supports the early completion of the LP SS detection.

[0463] Optional Example 6:

The time period d is a subset of time period D, or d is smaller than D. FIG2G is a schematic diagram of this method.

[0465] Optional Example 7:

[0466] The OOK modulation of the LPSS in time period D does not carry information. The time or frequency domain sequence of the OOK symbols of the LPSS in time period d carries information Q. Time period s is used for synchronization, or in other words, carries synchronization information. Time period d is a subset of time period D, or in other words, d is smaller than D. Time period s is a subset of time period D, or in other words, s is smaller than D. Figure 2H above is a schematic diagram of this method.

[0467] Optional Example 8:

[0468] The OOK modulation of the LPS in time period D carries no information. The time or frequency domain sequence of the OOK symbols of the LPS in multiple time periods d carries information Q. Time period s is used for synchronization, or in other words, carries synchronization information. Time period d is a subset of time period D, or d is smaller than D. Time period s is a subset of time period D, or s is smaller than D. Figure 2I above is a schematic diagram of this method.

[0469] Optional Example 9:

[0470] The OOK modulation of the LP SS in the time period D carries information Q, and the time domain or frequency domain sequence of the OOK symbols of the LP SS in the time period D does not carry information.

[0471] Optional Example 10:

[0472] The OOK modulation of the LP SS in the time period D does not carry information, and the time domain or frequency domain sequence of the OOK symbols of the LP SS in the time period D does not carry information.

[0473] Based on the above method, it is further defined that the information A, B, C, D, QA, QB, QC, etc. is combined with the information including at least one of the following:

[0474] Time-frequency synchronization information, cell ID information, area ID information, time interval information, repetition information, LP WUS partial wake-up information, LP WUS full wake-up information. (The first N symbols are the synchronization sequence, and the last M symbols are the cell ID, which can be included)

[0475] In one embodiment, when the time interval information carried is the time interval between the LP SS and the SSB, when a new UE using OFDM LR enters the cell coverage area and receives the LP SS, it can use this information to obtain the time domain location information for the MR to search for the SSB. If the UE is paged in the cell, the MR will directly search for the SSB / coreset0 at the corresponding location after waking up, thereby reducing the UE's blind detection time.

[0476] In one embodiment, when the frequency domain interval information carried is the frequency domain interval between the LP SS and the SSB, when a new UE using OFDM LR enters the cell coverage area and receives the LP SS, it can use this information to obtain the frequency domain location information for the MR to search for the SSB.
