[0067] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0068] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0069] 1. Low power wake up receiver (LP WUR).

[0070] The basic working principle of LP WUR is that the receiving end includes a first module and a second module. The first module is a main communication module, which is used to receive communication data transmitted by the sending end and send communication data. The second module is a low-power module, which is used to receive the low-power wake-up signal (LP-WUS) and low-power synchronization signal (LP-SS) sent by the sending end. The low-power wake-up signal is used to wake up the main communication module of the receiving end, and the low-power synchronization signal is used to provide time reference information and other information for receiving the low-power wake-up signal, for example, for performing radio resource management (RRM) measurement of the serving cell. It can also provide wake-up link management, such as determining whether to activate or deactivate LP-WUR based on the measurement results and shutting down the main receiver (MR). Among them, when the first module is not awakened by the second module, it is always in the closed state and does not send or receive data. When downlink data arrives, the second module detects the wake-up signal sent by the sending end, and the wake-up signal contains the terminal information. Then the second module triggers the first module to switch from the closed state to the working state to receive and send data. The second module can be turned on continuously or discontinuously, and can receive a low-power wake-up signal and a low-power synchronization signal when the second module is turned on.

[0071] 2. Low power wake-up signal.

[0072] In this embodiment, WUS may be a low-power wake-up signal.

[0073] To reduce a terminal's reception activity in standby mode, effectively shutting down the radio frequency (RF) and baseband (MODEM) modules, thereby significantly reducing power consumption during communication reception, this can be achieved by integrating the aforementioned low-power receiver into the terminal's receiving module. In one embodiment, this near-zero-power receiver eliminates the complex signal detection (e.g., amplification, filtering, quantization, etc.) required by the RF module and the signal processing required by the MODEM, relying solely on passive matched filtering and low-power signal processing.

[0074] In one embodiment, the low-power wake-up signal is generally a relatively simple on-off keying (OOK) signal, so that the receiver can obtain the wake-up notification through simple energy detection and subsequent possible sequence detection and identification processes. In another embodiment, the low-power wake-up signal can be an FSK signal, an OFDM signal, or a mixed signal of OFDM and OOK or FSK. In addition, while the terminal turns on the low-power receiver to receive the wake-up signal, the main receiver module can maintain a low power consumption level, thereby achieving power saving by receiving the wake-up signal.

[0075] Receiving the low-power wake-up signal can be applied to a terminal in an RRC idle (RRC idle) or RRC inactive (RRC inactive) state, and can also be applied to a terminal in an RRC connected (RRC_connected) state, thereby achieving terminal energy saving.

[0076] Since Orthogonal Frequency Division Multiplexing (OFDM) is commonly used in NR systems, OOK signals can be generated using OFDM signal generation methods. For example, the transmission or non-transmission of an OFDM-modulated sequence represents the ON / OFF state in the time domain. OOK signals can be received using receivers with lower power consumption, but such receivers have poor reception performance and coverage.

[0077] Furthermore, the OFDM modulated sequence in the modulation ON can further carry information through different sequences, for example, two sequences represent 0 and 1 information respectively, or four sequences represent 00, 01, 10, and 11 information respectively.

[0078] Optionally, for the waveform or modulation mode of on-off keying OOK superimposed on orthogonal frequency division multiplexing OFDM, part of the information is modulated by OOK, and the other part of the information is carried by an ON-level OFDM sequence.

[0079] Since demodulating the OFDM sequence requires a receiver capable of receiving OFDM signals, generally speaking, such receivers have better demodulation performance than low-power receivers that can only decode OOK signals.

[0080] 3. Low power synchronization signal.

[0081] The LP-SS signal is a signal that is sent periodically to convey time information. The receiving end can obtain time synchronization information by receiving the LP-SS signal. In some embodiments, mobility measurement or channel measurement can also be performed by receiving the LP-SS signal. Both LP-SS and LP-WUS are received by a low-power receiver. In one embodiment, LP-SS can be regarded as a downlink synchronization signal for LP-WUS reception. In another embodiment, the LP-SS signal can also be used for terminal mobility measurement, such as cell selection or cell reselection, cell handover, and other functions. In addition, optionally, the sequence of the LP-SS signal can have a certain correlation with the LP-WUS sequence. For example, the LP-SS signal sequence is part of the LP-WUS sequence.

[0082] To save energy, in the RRC idle or inactive state, the terminal can enable LP_WUR monitoring of LP-WUS instead of MR monitoring (Paging Occasion, PO) until it detects an LP-WUS indicating wakeup, at which point the MR resumes monitoring. While the terminal is monitoring LP-WUS, the MR can sleep. However, to maintain RRM measurements, under existing technologies, the MR must periodically wake up to perform RRM measurements because the serving cell's RRM measurements cannot be relaxed. Therefore, even if LP-WUS monitoring is used instead of MR monitoring for PO, the terminal's power consumption is not ideal due to the MR's periodic RRM measurements.

[0083] Therefore, LP-WUR can be used to measure LP-SS to relax or replace MR RRM measurements, significantly reducing terminal power consumption. However, in the RRC connected state, the terminal's MR rarely achieves the same sleep duration and depth as in RRC idle or RRC inactive. Furthermore, in an RRC connected state, terminal data transmission performance (such as latency and accuracy) must be guaranteed. Therefore, using LP-WUR to replace MR for RRM, RLM, and BFD measurements is unlikely to be considered.

[0084] The transmission processing method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0085] 2 , an embodiment of the present application provides a transmission processing method. As shown in FIG2 , the transmission processing method includes:

[0086] Step 201: The terminal detects a low power synchronization signal LP-SS;

[0087] Step 202: The terminal sends a target signal to a network device according to the LP-SS, where the target signal is used to trigger the network device to perform target transmission.

[0088] The target transmission includes at least one of the following:

[0089] Synchronous signal block SSB transmission;

[0090] System Information Block (SIB) transmission;

[0091] Paging transmission.

[0092] Optionally, the terminal detecting a low power synchronization signal LP-SS includes: the terminal detecting the LP-SS according to a configuration or instruction of a network-side device.

[0093] Optionally, before detecting LP-SS, the terminal obtains configuration information for LP-SS from a network device, or obtains instruction information indicating activation or initiation of LP-SS from the network device. For example, when the network device activates or initiates LP-SS transmission, the terminal begins detecting LP-SS.

[0094] In the embodiment of the present application, the network side device may send LP-SS in a low power state or low power mode, or may send LP-SS in a non-low power state or non-low power mode.

[0095] Furthermore, when sending LP-SS, network devices can skip the target transmission or send it at a longer transmission interval. This allows network devices to achieve even greater energy savings through LP-SS's low-power transmission and low-power operation modes.

[0096] Optionally, in some embodiments, SSB transmission is a necessary option for the target transmission, and the remaining transmissions may be optional.

[0097] For example, when a network device transmits LP-SS in a low-power state or low-power mode, the terminal may transmit a target signal to the network device based on the received LP-SS to trigger the network device to exit the low-power state or low-power mode. After the network device exits the low-power state or low-power mode, the network device may perform target transmission. In this way, by triggering the network device to perform target transmission through the terminal sending the target signal, the network device may enter a low-power state or low-power mode while not performing target transmission, thereby reducing the power consumption of the network device. Of course, in some embodiments, upon receiving the target signal, the network device may not switch between power consumption states or modes; for example, it may remain in the same power consumption state or mode before and after receiving the target signal.

[0098] Optionally, in some embodiments, step 202 may be understood or replaced by the terminal sending a target signal to the network device. For example, if LP-SS is used to indicate that the network has not enabled target transmission, the terminal may directly send the target signal to the network device after receiving the LP-SS.

[0099] Optionally, in step 202, the terminal transmitting the target signal according to the LP-SS may be understood as the terminal transmitting the target signal according to the measurement and reception of the LP-SS. For example, based on LP-SS reception, the terminal may obtain some downlink time-frequency domain synchronization information to assist in transmitting the target signal, or the terminal may obtain time-frequency domain location information for transmitting the target signal, or uplink power control information for transmitting the target signal, through the LP-SS.

[0100] Optionally, in some embodiments, when the network-side device sends the LP-SS in a non-low power consumption state or non-low power consumption mode, the terminal may not send the target signal.

[0101] Optionally, in some embodiments, the target signal may include a wake-up signal or a low-power wake-up signal.

[0102] In an embodiment of the present application, a terminal detects a low-power synchronization signal LP-SS; the terminal sends a target signal to a network-side device based on the LP-SS, and the target signal is used to trigger the network-side device to perform a target transmission; wherein the target transmission includes at least one of the following: synchronization signal block SSB transmission; system information block SIB transmission; paging transmission. In this way, since the terminal sends a target signal to trigger the network-side device to perform a target transmission, the network-side device can enter a low-power state or low-power mode when not performing a target transmission. Therefore, the embodiment of the present application reduces the power consumption of the network-side device. At the same time, since the network-side device does not need to perform a target transmission in the low-power state or low-power mode, resource overhead can be reduced.

[0103] Optionally, in some embodiments, the method further comprises:

[0104] The terminal obtains at least one of the following information according to the LP-SS:

[0105] Whether the network side device starts or performs the target transmission according to the target transmission period;

[0106] at least part of the configuration information of the target signal;

[0107] Information about the target transmission.

[0108] In an embodiment of the present application, the target transmission-related information may include time-frequency domain location information of the target transmission. The terminal may monitor the target transmission based on the obtained target transmission-related information, for example, the terminal monitors the target transmission based on the obtained time offset or monitoring time window of the target transmission.

[0109] Optionally, the terminal can send a target signal to trigger the network side device to perform target transmission based on the acquired configuration information of the target signal. For example, at least part of the configuration information of the target signal includes the sending timing of the target signal, then the terminal sends the target signal at the sending timing of the target signal to trigger the network side device to perform target transmission.

[0110] Optionally, after receiving the LP-SS, the terminal may perform a fourth operation according to the LP-SS and determine whether to send the target signal based on the result of the fourth operation. The fourth operation may include at least one of the following:

[0111] Monitor SSB;

[0112] determining whether the network-side device starts the target transmission or whether the target transmission is performed according to a target transmission period;

[0113] determining at least part of configuration information of the target signal;

[0114] Determine relevant information for the target transmission.

[0115] Optionally, the terminal can determine whether to transmit the target signal based on the SSB monitoring result. For example, if the terminal does not monitor the SSB, the terminal meets the target signal transmission conditions and can transmit the target signal. If the terminal monitors the SSB, it indicates that the network has resumed SSB transmission, and the terminal does not need to transmit the target signal. This can save resources for uplink transmission of the target signal and avoid transmission conflicts caused by target signals between multiple terminals.

[0116] Optionally, whether to send the target signal can be determined based on whether the network side device turns on the target transmission or whether the target transmission is performed according to the target transmission cycle. For example, when the terminal determines that the network side device has not turned on the target transmission or that the network side device has not performed the target transmission according to the target transmission cycle, the terminal sends the target signal; when the terminal determines that the network side device has turned on the target transmission or that the network side device performs the target transmission according to the target transmission cycle, the terminal does not send the target signal.

[0117] It should be noted that the target transmission period described above refers to a normal transmission period. If the network device does not send the target transmission according to the normal transmission period, for example, if the network device sends the target transmission according to the longer transmission period, the terminal's cell search or initial access delay will be longer. Therefore, in this case, the terminal also needs to send a target signal to trigger the network device to resume the normal transmission period to transmit the target transmission.

[0118] In some embodiments, the LP-SS may include at least partial configuration information of the target signal. The terminal may determine at least partial configuration information of the target signal based on the monitored LP-SS, and then send the target signal according to the determined at least partial configuration information.

[0119] In some embodiments, the LP-SS may include the target transmission related information. In this case, the terminal may perform target transmission related operations based on the target transmission related information when sending the target signal.

[0120] Optionally, in some embodiments, the LP-SS satisfies at least one of the following:

[0121] The LP-SS has an association relationship with the target transmission in the time-frequency domain, or the LP-SS indicates relevant parameters of the target transmission;

[0122] Different sequences of the LP-SS are respectively associated with whether the network side device starts the target transmission, or the LP-SS instructs the network side device whether to start the target transmission;

[0123] Different sequences of the LP-SS are respectively associated with whether the network side device performs the target transmission according to the target transmission period, or the LP-SS instructs the network side device whether to perform the target transmission according to the target transmission period.

[0124] In one embodiment, the target transmission refers to SSB transmission. That is, there is a time-frequency domain association between the LP-SS and SSB. For example, the synchronization grid where the LP-SS resides corresponds one-to-one or one-to-many to the synchronization grid where the SSB resides. For another example, the LP-SS indicates the frequency or time domain location information of the SSB.

[0125] In this embodiment of the present application, different LP-SS sequences are associated with whether the network device has initiated the target transmission. This can be understood as follows: a first type of LP-SS sequence corresponds to when the network device has initiated the target transmission, and a second type of LP-SS sequence corresponds to when the network device has not initiated the target transmission. For example, the network device may use the first type of sequence to send the LP-SS when the target transmission is initiated, and use the second type of sequence to send the LP-SS when the target transmission is not initiated.

[0126] Optionally, the LP-SS may further carry indication information for explicitly indicating to the network side device whether to start the target transmission.

[0127] It should be understood that in the embodiment of the present application, the network side device starting the target transmission can be understood or replaced by the network side device having or about to start the target transmission.

[0128] It should be understood that, in this embodiment, the network side device starts the target transmission, which can be understood as executing the target transmission, or performing the target transmission.

[0129] Optionally, the LP-SS may further carry indication information for explicitly instructing the network-side device whether to perform the target transmission according to the target transmission period. Alternatively, when the LP-SS carries an indication of the target transmission period, the network-side device may be instructed by default to perform the target transmission according to the target transmission period. When the LP-SS does not carry an indication of the target transmission period, the network-side device may be instructed by default not to perform the target transmission according to the target transmission period.

[0130] Optionally, the network-side device may implicitly indicate whether the target transmission is performed according to the target transmission period by sending different types of sequences. For example, the network-side device may indicate that the target transmission is performed according to the target transmission period by sending LP-SS using a first type of sequence; and may indicate that the target transmission is not performed according to the target transmission period by sending LP-SS using a second type of sequence. In this case, the target transmission period may be agreed upon by the protocol or pre-configured by the network-side device, or carried in the LP-SS.

[0131] Optionally, in some embodiments, the sending timing of the target signal is determined according to the time domain position of the LP-SS.

[0132] In the embodiment of the present application, after receiving the LP-SS, the terminal can determine the sending timing of the target signal according to the time domain position of the LP-SS, and can send the target signal at the determined sending timing if the sending conditions of the target signal are met.

[0133] Optionally, in some embodiments, the target signal sending condition includes at least one of the following:

[0134] The terminal fails to monitor the target transmission;

[0135] The terminal determines that the network side device has not started the target transmission or has not performed the target transmission according to the target transmission period.

[0136] In embodiments of the present application, the terminal may transmit the target signal if the target signal transmission conditions are met. For example, the terminal may perform the fourth operation according to LP-SS and, after performing the fourth operation, determine whether the target signal transmission conditions are met. If the target signal transmission conditions are determined to be met, the terminal transmits the target signal to trigger the network-side device to perform the target transmission.

[0137] Optionally, the terminal failing to monitor the SSB may be understood as at least one of the following:

[0138] The terminal fails to monitor the SSB within the monitoring position or monitoring time window of the SSB determined according to the LP-SS;

[0139] The terminal has not detected SSB for a period of time.

[0140] Optionally, in some embodiments, after the terminal sends a wake-up signal to the network-side device according to the LP-SS, the method further includes at least one of the following:

[0141] The terminal monitors the target transmission;

[0142] The terminal performs a first operation according to the target transmission;

[0143] The first operation includes at least one of the following: initial cell search; synchronization; measurement; link failure recovery; and random access.

[0144] Optionally, in some embodiments, at least one of a monitoring position, a monitoring offset, and a monitoring time window of the target transmission is determined according to a time domain position of the LP-SS or a sending position of the target signal.

[0145] For example, the listening position of the target transmission is configured relative to the time domain position of the LP-SS, or the listening position of the target transmission is configured relative to the sending position of the LP-target signal.

[0146] Furthermore, when the network-side device configures the LP-target signal transmission timing and period, the LP-target signal transmission timing can be configured relative to the LP-SS, and the LP-target signal period can be an integer multiple of the SSB period. In this case, the LP-target signal transmission timing is fixed relative to the SSB. Similarly, for LP-SS, the LP-target signal configuration described above can be used.

[0147] Optionally, in some embodiments, the method further comprises:

[0148] The terminal starts to monitor the target transmission within a specific monitoring time window or the terminal starts to monitor the target transmission after a specific time offset.

[0149] In this embodiment of the present application, the specific monitoring time window may be a preset monitoring time window or a monitoring time window determined based on the time domain position of the LP-SS or the transmission position of the target signal. Similarly, the specific time offset may be a preset time offset or a time offset determined based on the time domain position of the LP-SS or the transmission position of the target signal.

[0150] For example, the network side device configures the specific time window or offset relative to the LP-SS or LP-target signal, and after sending the target signal, the terminal detects the target transmission within the specific time window or after the specific time offset.

[0151] Optionally, the terminal detecting the target transmission within a specific time window or after a specific time offset can be understood as: the terminal caches data within the specific time window to detect the target transmission, or the terminal starts caching data for a T time period after the specific offset to detect the target transmission.

[0152] Optionally, the T is configured by the network side or agreed upon by a protocol, or indicated by LP-SS.

[0153] Optionally, T is less than or equal to the period of the target transmission.

[0156] If the terminal does not monitor the target transmission and the number of times the target signal is sent is less than a first preset number, the terminal sends the target signal again;

[0157] If the terminal does not monitor the target transmission and the number of times the terminal sends the target signal is greater than or equal to a first preset number of times, the terminal performs a second operation;

[0158] The second operation includes at least one of the following:

[0159] Perform cell search or initial access based on SSB;

[0160] Switch to other frequency locations or other cells on the same frequency to perform LP-SS-based cell search or initial access;

[0161] Switch to other frequency locations or other cells on the same frequency for SSB-based cell search or initial access.

[0163] Switching to other frequency positions or other cells of the same frequency can be understood as performing cell switching. Specifically, the terminal can directly perform cell search or initial access based on LP-SS or SSB in the switched cell.

[0164] In an embodiment of the present application, if SSB is not detected after sending the target signal (within a specific time period), the terminal sends the target signal again until the maximum number of transmissions N is reached, triggering the execution of the second operation.

[0165] Optionally, in some embodiments, after the terminal sends the target signal to the network-side device according to the LP-SS, the method further includes:

[0166] The terminal monitors first information, where the first information is a confirmation message of the target signal.

[0167] In an embodiment of the present application, after receiving the target signal, the network side device may send first information to the terminal based on the target signal.

[0168] Optionally, in some embodiments, after the terminal monitors the first information, the method further includes at least one of the following:

[0169] If the terminal does not detect the first information and the number of times the target signal is sent is less than a second preset number, the terminal sends the target signal again;

[0170] If the terminal does not detect the first information and the number of times the terminal sends the target signal is greater than or equal to a second preset number of times, the terminal performs a second operation;

[0171] The second operation includes at least one of the following:

[0172] Perform cell search or initial access based on SSB;

[0173] Switch to other frequency locations or other cells on the same frequency to perform LP-SS-based cell search or initial access;

[0174] Switch to other frequency locations or other cells on the same frequency for SSB-based cell search or initial access.

[0175] In the embodiment of the present application, upon receiving the first information, the terminal may begin monitoring the target transmission. If the terminal does not receive the first information, it may resend the target signal until a maximum number of transmissions N is reached. If the terminal still does not detect the first information after sending the target signal the maximum number of times N, it may trigger execution of the second operation.

[0176] Optionally, in some embodiments, the first information is used to indicate relevant information of the target transmission.

[0177] Optionally, in some embodiments, the target transmission related information includes at least one of the following:

[0188] Optionally, in some embodiments, at least one of the configuration information of the target signal and the relevant information of the target transmission may be indicated by a protocol agreement or by the LP-SS.

[0210] Sequence and Load sections.

[0211] The above sequence may include one or more candidate sequences.

[0212] Optionally, in some embodiments, the terminal sending a target signal to a network-side device according to the LP-SS includes:

[0213] The terminal repeatedly sends a target signal to a network-side device according to the LP-SS;

[0226] Optionally, in some embodiments, the method further comprises:

[0232] In the embodiment of the present application, the above-mentioned frequency position can be understood or replaced by a frequency point.

[0233] Optionally, when the measurement result of the LP-SS is lower than a preset threshold, the terminal can turn on the main receiver and fall back to the state of using SSB for cell search or initial access; or switch to other cells (cells corresponding to other frequency positions or other cells with the same frequency) and use SSB or LP-SS for cell search or initial access.

[0234] In order to better understand the present application, some examples are provided below for illustration.

[0235] In some embodiments, the following process steps may be included:

[0236] Step 11: The terminal detects LP-SS.

[0237] In one example, the terminal can obtain coarse time and frequency synchronization information through LP-SS (coarse means relative to the terminal obtaining time and frequency synchronization information directly through SSB reception). The LP-SS is sent by the network side device, and the terminal detects and receives it through a low-power receiver, so that the terminal can achieve energy saving. How the terminal obtains coarse time and frequency synchronization information by detecting LP-SS is not limited here. In addition, it is understandable that the terminal can assist in the subsequent SSB detection through the detection of LP-SS. Specifically, the terminal obtains time and frequency domain information through LP-SS, which can narrow the time and frequency domain position detection range of the SSB, thereby reducing the buffer complexity and terminal power consumption required for detecting and demodulating the SSB during the initial search process of the terminal.

[0238] Optionally, information such as the LP-SS detection timing, period, LP-SS sequence, and LP-SS modulation and coding scheme may be configured through protocol agreement.

[0239] In step 12, the terminal detects the SSB based on the LP-SS detection. Alternatively, the terminal determines whether the network device has enabled the target transmission based on the LP-SS detection. (For example, the LP-SS may carry an indication of whether the target transmission is enabled, or different LP-SS sequences may provide an implicit indication.)

[0240] Optionally, when the terminal does not detect SSB, the terminal sends WUS to trigger the network side device to perform target transmission.

[0241] Optionally, when the terminal detects SSB, the terminal does not send WUS.

[0242] Optionally, when it is determined that the network side device has not enabled the target transmission, the terminal sends a WUS to trigger the network side device to perform the target transmission.

[0243] Optionally, when it is determined that the network side device starts the target transmission, the terminal does not send a WUS.

[0244] It should be understood that if the terminal has restored or enabled SSB transmission before entering the cell, the terminal does not need to send WUS to trigger SSB. This can save uplink resources and avoid WUS transmission conflicts between multiple UEs.

[0245] In one example, when the terminal detects the LP-SS and needs to perform cell search, initial access, or cell camping, the terminal can trigger the network side device to perform target transmission by sending a WUS.

[0246] It is understandable that before the terminal sends the WUS, that is, when the terminal is in the LP-SS detection process, the terminal assumes that the network side device does not send the target transmission.

[0247] In one example, before step 12, that is, before the terminal sends the WUS, it is necessary to obtain WUS configuration information and determine candidate WUS sending timings. The terminal sends the WUS at the candidate WUS sending timings.

[0248] Optionally, the terminal may obtain the configuration information of the WUS through at least one of a protocol agreement and a network instruction.

[0249] Mode 1: The terminal obtains the configuration information of the WUS through the LP-SS, that is, the LP-SS carries the indication information of the WUS configuration.

[0250] Method 2: The terminal obtains WUS configuration information through LP-SS and protocol agreement.

[0251] In one example, the LP-SS carries and the protocol specifies various WUS configuration information. For example, the LP-SS carries WUS transmission timing indications, and the protocol specifies the number of WUS transmission opportunities, the WUS transmission period, the interval between each WUS transmission opportunity, and the frequency domain location of the WUS.

[0252] In one example, the protocol specifies a WUS configuration table, which contains numerous WUS configuration parameters. Each row of the table is a set of WUS configurations. LP-SS carries a table row index to indicate which set of WUS configurations to apply.

[0253] Optionally, after the terminal sends the WUS, the following steps 13a or 13b may be performed.

[0254] In step 13a, the terminal monitors the first information sent by the network side device, where the first information is confirmation information sent by the network side device receiving the WUS.

[0255] Optionally, the terminal starts monitoring the target transmission when receiving the first information. That is, the terminal does not start monitoring the target transmission if it does not receive the first information.

[0256] In step 13b, the terminal monitors the target transmission.

[0257] Optionally, the terminal detects the target transmission within a specific time range or a specific time window or after a specific time offset.

[0258] Optionally, the time offset may be understood as the distance between a target transmission closest to the LP-SS, for example, as shown in the relative offset in FIG3 .

[0259] In one example, the LP-SS period is a multiple of the SSB (target transmission) period. The LP-SS start offset (e.g., offset 1 in Figure 3) and the SSB start offset (e.g., offset 2 in Figure 3) are configured by the network or agreed upon by the protocol. As shown in Figure 3, both the LP-SS and SSB offsets are configured relative to the same starting position (e.g., system frame number (SFN) 0). In one embodiment, the LP-SS start offset is the same as the SSB start offset. In another embodiment, the difference between the LP-SS and SSB start offsets (the relative offset in the figure) is a specific value.

[0260] In one example, the specific time window or specific time offset (corresponding to the relative offset in FIG. 3 ) is indicated by the LP-SS. For example, the terminal begins monitoring the target transmission after the time offset indicated by the LP-SS (e.g., the relative offset in FIG. 3 ). In another example, the terminal monitors the target transmission within the target transmission monitoring time window indicated by the LP-SS. For example, the target transmission includes SSB.

[0261] The target transmission is received by the terminal's main communication module. The LP-SS is received by the terminal's low-power module. Therefore, before the terminal triggers the network-side device to perform the target transmission, the terminal can only turn on the low-power module to monitor and send low-power signals.

[0262] In one example, if the terminal does not detect an SSB within a specific time interval after sending a WUS, or does not detect the first information, the terminal sends the WUS again. Optionally, the maximum number of times the WUS is sent is configured by the network side or agreed upon by the protocol, or indicated by the LP-SS.

[0263] Optionally, LP-SS can be used to assist SSB in preliminary cell search or synchronization. Specifically, for example, LP-SS assists SSB in determining the cell center frequency, the sync raster ID where the SSB is located, the initial time domain location information of the SSB, and the SSB period.

[0264] In addition, it should be noted that the detection of LP-SS can also help the terminal to send UL WUS information.

[0265] Optionally, the sending timing of WUS may also be referred to as the WUS sending time-frequency position.

[0266] In one example, the WUS is sent at any time position. In this case, for the network-side device, the base station needs to continuously monitor the WUS sent by the terminal in the time domain;

[0267] In one example, the WUS transmission timing is determined relative to the time-frequency domain position of the LP-SS; for example, the starting position of the WUS transmission timing is a specific time offset or a specific time interval away from the starting or ending position of the LP-SS.

[0268] For example, the LP-SS carries WUS transmission timing indication information, which indicates the time offset of the WUS relative to the LP-SS. Furthermore, within an LP-SS cycle, the protocol stipulates or the LP-SS indicates multiple candidate WUS transmission timings. As shown in Figure 4, there are three WUS occasions within each LP-SS cycle. The interval size of each WUS occasion can be agreed upon. The LP-SS carries the UL WUS time offset indication relative to the LP-SS.

[0269] Optionally, in an example, the time domain synchronization of WUS transmission refers to the timing of base stations of other cells or radio access technologies (Radio Access Technology, RAT), and the WUS is transmitted at a specific time domain position based on this.

[0270] In one example, for a network-side device, the protocol pre-defines or the base station configures or the LP-SS indicates the same WUS configuration information to some or all terminals.

[0271] It should be understood that in the above embodiment, the LP-SS can indicate the relative offset of the target transmission and the relative offset of the WUS transmission timing. In other words, when sending the WUS, the terminal can determine the location information of the target transmission relative to the WUS based on the above two relative offsets.

[0272] Optionally, the waveform or modulation method of WUS.

[0273] In one example, WUS is generated based on an OOK waveform or modulation scheme, including but not limited to OOK-1, OOK-2, OOK-4, etc.;

[0274] In one example, WUS is generated based on an OFDM waveform or modulation scheme, including but not limited to OFDM, DFT-s-OFDM, MB-OFDM, F-OFDM, etc.;

[0275] In one example, the WUS is generated based on a pulse waveform or modulation method, including but not limited to PWM modulation, PPM modulation, PCM modulation, etc.;

[0276] In one example, the WUS is generated based on an FSK waveform or modulation scheme, including but not limited to 2FSK, 4FSK, etc.

[0277] Optionally, duplication of WUS.

[0278] In one example, the WUS is repeatedly transmitted L times in the time domain, and the L transmissions have the same content and the same transmission method (for example, omnidirectional transmission);

[0279] In one example, the WUS is repeatedly transmitted L times in the time domain, with the same content transmitted L times, but transmitted in different beam directions.

[0280] In one example, WUS is repeatedly sent L times in the time domain, with different indexes (other contents are the same) in the L transmissions, and is sent in different beam directions;

[0281] In one example, the WUS is repeatedly transmitted P times in the frequency domain.

[0282] In one example, if no SSB is detected within a specific period of time after sending the WUS, the terminal sends the WUS again until the maximum number of transmission times N.

[0283] If the terminal still fails to detect the SSB after sending the WUS for the maximum number of times N, it starts a cell search based on LP-SS or SSB.

[0284] In one example, after sending the WUS, the terminal monitors first information, where the first information is confirmation information received by the network side from the WUS.

[0285] Furthermore, upon receiving the first information, the terminal starts monitoring the target transmission.

[0286] In an example, when the terminal does not receive the first information, the terminal sends the WUS again until the maximum number of sending times M is reached.

[0287] If the terminal still fails to detect the SSB after sending the WUS for the maximum number of times M, it will restart the cell search based on LP-SS or start based on SSB.

[0288] Furthermore, the first information indicates relevant information of the target transmission. For example, the relevant information of the target transmission includes time-frequency domain position information of the SSB (relative to the time-frequency domain position of the LP-SS or the first information).

[0289] Optionally, the WUS sending condition may include at least one of the following:

[0290] Prepare for initial access;

[0291] Prepare for initial access on a frequency band capable of WUS triggering;

[0292] No SSB is detected during cell search on a frequency band supported by the terminal;

[0293] No SSB is detected during cell search on a frequency band supported by the terminal that cannot trigger WUS;

[0294] After the terminal performs cell search for a period of time T, no SSB is detected;

[0295] A radio link failure occurs on the terminal.

[0296] The terminal performs radio link recovery.

[0297] It should be noted that since the WUS sending timing is broadcast, that is, the network side device configures the WUS sending timing for all terminals in the cell, it is possible that multiple terminals choose the same WUS sending timing to send WUS, resulting in a conflict.

[0298] To further reduce collisions, one approach is to configure multiple WUS transmission times on the network side, allowing the terminal to randomly select a WUS transmission time to transmit. Another approach is to establish a protocol-defined relationship between the WUS transmission times configured on the network side and the terminals, evenly assigning different UEs to different WUS transmission times and achieving the effect of terminal grouping.

[0299] Another method can be used to reduce the probability that network equipment will not be able to demodulate WUS signals when multiple terminals send them simultaneously. For example, a sequence with good autocorrelation or cross-correlation can be designed to combat interference (neighboring cell interference or multi-user interference) and improve demodulation performance.

[0300] Optionally, the network device can configure a WUS sequence pool containing multiple WUS sequences. The terminal selects a WUS sequence from the pool randomly or according to a specific method and then sends the WUS. Different WUS sequences have high orthogonality or low correlation. This allows different UEs to be distinguished, thereby reducing the probability of collisions.

[0301] LP-SS measurement fallback.

[0302] In one example, when the measurement result of the LP-SS is lower than a specific threshold value (including a case where the LP-SS cannot be detected), the terminal (with the main receiver turned on) falls back to using SSB for cell search or initial access, or the terminal switches to other cells (cells corresponding to other frequency positions or other cells of the same frequency) for cell search or initial access.

[0303] 5 , an embodiment of the present application further provides a transmission processing method. As shown in FIG5 , the transmission processing method includes:

[0304] Step 501: The network side device sends a low power synchronization signal LP-SS;

[0305] Step 502: The network-side device receives a target signal from the terminal;

[0306] Step 503: the network side device performs target transmission according to the target signal;
