[0065] For ease of understanding, some content related to the embodiments of this application is described below:

[0066] For ease of understanding, some content related to the embodiments of this application is described below:

[0067] I. Low power wake up receiver (LP WUR).

[0068] The basic working principle of LP WUR is that the receiving end includes a first module and a second module. The first module is the main communication module, which is used to receive and transmit the communication data transmitted by the sending end. The second module is the low-power module, which is used to receive the low-power wake-up signal (LP-WUS) and the low-power synchronization signal (LP-SS) transmitted 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, it is used for radio resource management (RRM) measurement of the serving cell, and can also provide wake-up link management, such as determining whether to activate or deactivate LP WUR according to the measurement results, and turning off the main receiver (MR). Among them, when the first module is not woken up by the second module, it is always in the off state and does not send or receive data. When there is downlink data arriving, the second module detects the wake-up signal transmitted by the sending end, and if the wake-up signal contains the information of this terminal, the second module triggers the first module to switch from the off state to the working state for data reception and transmission. The second module can be continuously turned on or not continuously turned on. When the second module is turned on, it can receive the low-power wake-up signal and the low-power synchronization signal.

[0069] II. Low-power wake-up signal.

[0070] In this embodiment, WUS can be the low-power wake-up signal.

[0071] In order to reduce the receiving activities of the terminal in the standby state, so that the radio frequency (RF) and baseband (MODEM) modules are truly turned off, thus greatly reducing the power consumption of communication reception, it can be achieved by introducing the above-mentioned low-power receiver into the receiving module of the terminal. In one embodiment, this near "zero" power receiver does not require complex signal detection (such as amplification, filtering, quantization, etc.) of the RF module and signal processing of the MODEM, but only relies on passive matched filtering and signal processing with relatively low power consumption.

[0072] In one embodiment, the low-power wake-up signal is generally some relatively simple on-off keying (OOK) signals, 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 hybrid 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 operate at a relatively low power consumption level, so as to achieve power saving by receiving the wake-up signal.

[0073] The reception of the low-power wake-up signal can be applied to terminals in the RRC idle or RRC inactive state, and can also be applied to terminals in the RRC connected state, so as to achieve energy saving for the terminal.

[0074] Since in the NR system, the orthogonal frequency division multiplexing (OFDM) signal modulation method is generally adopted. Then, the OOK signal can be generated by the OFDM signal generation method. For example, by sending or not sending the sequence modulated by OFDM, it represents ON / OFF in the time domain. The OOK signal can be received by a receiver with lower power consumption, but the reception performance of this type of receiver is poor and the coverage is also poor.

[0075] Furthermore, the OFDM modulated sequence in the ON modulation 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.

[0076] Optionally, for the waveform or modulation method of on-off keying OOK superimposed on orthogonal frequency division multiplexing OFDM, a part of the information is modulated by OOK, and another part of the information is carried by the OFDM sequence of the ON level.

[0077] Since demodulating the OFDM sequence requires a receiver with the ability to receive OFDM signals. Generally speaking, the demodulation performance of this type of receiver is better than that of this type of low-power receiver that can only demodulate OOK signals.

[0078] III. Low-power synchronization signal.

[0079] The LP-SS signal is a periodically transmitted signal used to convey time information. The receiving end can obtain time synchronization information by receiving the LP-SS signal. In some embodiments, mobility measurements or channel measurements 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 measurements, such as cell selection or reselection, cell handover, etc. Additionally, optionally, there may be a certain correlation between the sequence of the LP-SS signal and the LP-WUS sequence. For example, the LP-SS signal sequence is a part of the LP-WUS sequence.

[0080] For energy saving, in the RRC idle or inactive state, the terminal can turn on the LP_WUR to listen for LP-WUS instead of the MR to listen for (Paging Occasion, PO) until the LP-WUS indicating wake-up is detected, and then the MR resumes listening. When the terminal is listening for LP-WUS, the terminal MR can sleep. However, for maintaining RRM measurements, in the prior art, since the RRM measurements of the serving cell cannot be relaxed, the terminal MR has to wake up periodically for RRM measurements. Thus, even if LP-WUS listening is applied to replace the MR for PO listening, the energy saving of the terminal power consumption is not ideal due to the periodic RRM measurements of the MR.

[0081] Therefore, the LP-WUR can be used to measure LP-SS to relax or replace the MR for RRM measurements, so that a very large saving in terminal power consumption can be achieved. However, in the RRC connected state, in fact, the MR of the terminal can hardly reach the sleep duration and sleep depth as in the RRC idle or RRC inactive states. In addition, in the RRC connected state, it is necessary to ensure the data transmission performance of the terminal (such as latency and accuracy, etc.). Therefore, it is mostly not considered to use the LP-WUR to replace the MR for RRM, RLM, and BFD measurements.

[0082] The following will, with reference to the accompanying drawings, through some embodiments and their application scenarios, elaborate in detail on the transmission processing method provided by the embodiments of the present application.

[0083] Refer to Figure 2 , the embodiments of the present application provide a transmission processing method, as Figure 2 shown, the transmission processing method includes:

[0084] Step 201, the terminal detects the low-power synchronization signal LP-SS;

[0085] Step 202: The terminal sends a target signal to the network - side device according to the LP - SS, where the target signal is used to trigger the network - side device to perform target transmission.

[0086] Among them, the target transmission includes at least one of the following:

[0087] Synchronization signal block (SSB) transmission;

[0088] System Information Block (SIB) transmission;

[0089] Paging transmission.

[0090] Optionally, the terminal detecting the low - power synchronization signal LP - SS includes: The terminal detects the LP - SS according to the configuration or indication of the network - side device.

[0091] Optionally, before detecting the LP - SS, the terminal obtains the configuration information of the LP - SS from the network - side device, or obtains the indication information for activating or starting the LP - SS from the network - side device. For example, when the network - side device activates or starts to send the LP - SS, the terminal starts to detect the LP - SS.

[0092] In the embodiments of the present application, the network - side device can send the LP - SS in a low - power state or low - power mode, or can also send the LP - SS in a non - low - power state or non - low - power mode.

[0093] In addition, when the network - side device sends the LP - SS, it can not send the target transmission or send the target transmission according to a larger transmission period. Thus, the network - side device can achieve more energy savings through the low - power transmission of the LP - SS and the low - power working mode.

[0094] Optionally, in some embodiments, the SSB transmission is a necessary option for the target transmission, and the remaining transmissions can be optional.

[0095] For example, when the network - side device sends the LP - SS in a low - power state or low - power mode, the terminal can send a target signal to the network - side device according to the received LP - SS to trigger the network - side device to exit the low - power state or low - power mode. After the network - side device exits the low - power state or low - power mode, the network - side device can perform the target transmission. In this way, by the terminal sending the target signal to trigger the network - side device to perform the target transmission, the network - side device can enter the low - power state or low - power mode during the process of not performing the target transmission, so the power consumption of the network - side device can be reduced. Of course, in some embodiments, when the network - side device receives the target signal, it can not perform the switching of the power - consumption state or power - consumption mode. For example, it is in the same power - consumption state or power - consumption mode before and after receiving the target signal.

[0096] Optionally, in some embodiments, step 202 may be understood or replaced as the terminal sending a target signal to the network-side device. For example, when the LP-SS is used to indicate that the network-side does not initiate the target transmission, after receiving the LP-SS, the terminal may directly send a target signal to the network-side device.

[0097] Optionally, in step 202, the terminal sending a target signal according to the LP-SS may be understood as the terminal sending a target signal based on the measurement and reception of the LP-SS. For example, based on the reception of the LP-SS, the terminal may obtain some downlink time-frequency domain synchronization information to assist in sending the target signal, or the terminal may obtain the time-frequency domain position information of the target signal or the uplink power control information of the target signal through the LP-SS.

[0098] Optionally, in some embodiments, when the network-side device sends the LP-SS in a non-low-power state or non-low-power mode, the terminal may not send a target signal.

[0099] Optionally, in some embodiments, the above target signal may include a wake-up signal or a low-power wake-up signal.

[0100] In the embodiments of the present application, the terminal detects the low-power synchronization signal LP-SS; the terminal sends a target signal to the network-side device according to the LP-SS, and the target signal is used to trigger the network-side device to perform 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 network-side device is triggered to perform target transmission by the terminal sending a target signal, the network-side device can enter a low-power state or low-power mode during the process of not performing target transmission. Therefore, the embodiments of the present application reduce the power consumption of the network-side device. At the same time, since the network-side device does not need to perform target transmission in the low-power state or low-power mode, the resource overhead can be reduced.

[0101] Optionally, in some embodiments, the method further includes:

[0102] The terminal obtains at least one of the following information according to the LP-SS:

[0103] Whether the network-side device initiates or executes the target transmission according to a target transmission period;

[0104] At least partial configuration information of the target signal;

[0105] Relevant information of the target transmission.

[0106] In the embodiments of the present application, the relevant information of the target transmission may include the time-frequency domain position information of the target transmission. The terminal may perform monitoring of the target transmission according to the obtained relevant information of the target transmission. For example, the terminal performs monitoring of the target transmission according to the obtained time offset of the target transmission or the monitoring time window.

[0107] Optionally, the terminal may send a target signal according to the obtained configuration information of the target signal to trigger the network-side device to perform the target transmission. For example, if at least part of the configuration information of the target signal includes the transmission timing of the target signal, the terminal sends the target signal at the transmission timing of the target signal to trigger the network-side device to perform the target transmission.

[0108] Optionally, after receiving the above LP-SS, the terminal may perform a fourth operation according to the LP-SS, and may determine whether to send a target signal according to the execution result of the fourth operation. The fourth operation may include at least one of the following:

[0109] Monitor the SSB;

[0110] Determine whether the network-side device enables the target transmission or performs the target transmission according to the target transmission period;

[0111] Determine at least part of the configuration information of the target signal;

[0112] Determine the relevant information of the target transmission.

[0113] Optionally, the terminal may determine whether to send a target signal according to the monitoring result of the SSB. For example, when the terminal does not monitor the SSB and the terminal meets the target signal sending condition, the terminal may send the target signal; when the terminal monitors the SSB, it indicates that the network has resumed sending the SSB, and the terminal does not need to send the target signal anymore. This can save the resources for sending the target signal uplink and avoid transmission conflicts caused by target signals among multiple terminals.

[0114] Optionally, it may be determined whether to send a target signal according to whether the network-side device enables the target transmission or performs the target transmission according to the target transmission period. For example, when the terminal determines that the network-side device does not enable the target transmission or determines that the network-side device does not perform the target transmission according to the target transmission period, the terminal sends the target signal; when the terminal determines that the network-side device enables the target transmission or determines that the network-side device performs the target transmission according to the target transmission period, the terminal does not send the target signal.

[0115] It should be noted that the above-mentioned target transmission period refers to the normal transmission period. When the network-side device fails to send the target transmission according to the normal transmission period, for example, when the network-side device sends the target transmission according to the larger transmission period, the cell search or initial access delay of the terminal will be relatively large. Therefore, in this case, the terminal also needs to send a target signal to trigger the network-side device to resume the normal transmission period for transmitting the target transmission.

[0116] In some embodiments, the above 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.

[0117] In some embodiments, the above LP-SS may include the relevant information of the target transmission. At this time, the terminal may perform relevant operations of the target transmission according to the relevant information of the target transmission when sending the target signal.

[0118] Optionally, in some embodiments, the LP-SS satisfies at least one of the following:

[0119] The LP-SS has a time-frequency domain association relationship with the target transmission, or the LP-SS indicates the relevant parameters of the target transmission;

[0120] Different sequences of the LP-SS are respectively associated with whether the network-side device starts the target transmission, or the LP-SS indicates whether the network-side device enables the target transmission;

[0121] 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 indicates whether the network-side device performs the target transmission according to the target transmission period.

[0122] In one embodiment, the above target transmission refers to SSB transmission. That is, there is a time-frequency domain association relationship between the LP-SS and the SSB. For example, there is a one-to-one correspondence or a one-to-many correspondence between the synchronization grid where the LP-SS is located and the SSB synchronization grid. Another example is that the LP-SS indicates the frequency domain or time domain position information of the SSB, etc.

[0123] In the embodiments of the present application, the different sequences of the LP-SS are respectively associated with whether the network-side device starts the target transmission, which can be understood as that the first type of sequence of the LP-SS corresponds to the network-side device starting the target transmission, and the second type of sequence of the LP-SS corresponds to the network-side device not starting the target transmission. For example, the network-side device can use the first type of sequence to send the LP-SS when starting the target transmission; and use the second type of sequence to send the LP-SS when not starting the target transmission.

[0124] Optionally, indication information can also be carried in the LP-SS for explicitly indicating whether the network-side device starts the target transmission.

[0125] It should be understood that in the embodiments of the present application, the network-side device enabling the target transmission can be understood or replaced with the network-side device having already or about to enable the target transmission.

[0126] It should be understood that in this embodiment, for the network-side device to enable the target transmission can be understood as performing the target transmission or carrying out the target transmission.

[0127] Optionally, indication information can also be carried in the LP-SS for explicitly indicating whether the network-side device executes the target transmission according to the target transmission period. Also, when the indication of the target transmission period is carried in the LP-SS, it is default to indicate that the network-side device executes the target transmission according to the target transmission period; when the indication of the target transmission period is not carried in the LP-SS, it is default to indicate that the network-side device does not execute the target transmission according to the target transmission period.

[0128] Optionally, the network-side device can implicitly indicate whether the network-side device executes the target transmission according to the target transmission period by sending different types of sequences. For example, when the network-side device sends the LP-SS through the first type of sequence, it can indicate that the target transmission is executed according to the target transmission period; when the network-side device sends the LP-SS through the second type of sequence, it can indicate that the target transmission is not executed according to the target transmission period. At this time, the target transmission period can be agreed by the protocol or pre-configured by the network-side device, or carried in the LP-SS.

[0129] Optionally, in some embodiments, the transmission timing of the target signal is determined according to the time-domain position of the LP-SS.

[0130] In the embodiments of the present application, after receiving the LP-SS, the terminal can determine the transmission timing of the target signal according to the time-domain position of the LP-SS, and when the transmission conditions of the target signal are met, the target signal can be sent at the determined transmission timing.

[0131] Optionally, in some embodiments, the transmission condition of the target signal includes at least one of the following:

[0132] The terminal does not monitor the target transmission;

[0133] The terminal determines that the network-side device does not enable the target transmission or does not perform the target transmission according to the target transmission period.

[0134] In the embodiments of the present application, when the transmission condition of the target signal is satisfied, the terminal may send the target signal. For example, the terminal may perform a fourth operation according to the LP-SS, and determine whether the transmission condition of the target signal is satisfied after performing the fourth operation. When it is determined that the transmission condition of the target signal is satisfied, the target signal is sent to trigger the network-side device to perform the target transmission.

[0135] Optionally, the situation that the terminal does not monitor the SSB may be understood as at least one of the following:

[0136] The terminal does not monitor the SSB within the monitoring position or monitoring time window of the SSB determined according to the LP-SS;

[0137] The terminal does not monitor the SSB within a period of time.

[0138] 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:

[0139] The terminal monitors the target transmission;

[0140] The terminal performs a first operation according to the target transmission;

[0141] Wherein, the first operation includes at least one of the following: initial cell search; synchronization; measurement; link failure recovery; random access.

[0142] Optionally, in some embodiments, at least one of the monitoring position, monitoring offset, and monitoring time window of the target transmission is determined according to the time-domain position of the LP-SS or the transmission position of the target signal.

[0143] For example, the monitoring position of the target transmission is configured relative to the time-domain position of the LP-SS, or the monitoring position of the target transmission is configured relative to the transmission position of the LP-target signal.

[0144] Further, when the network - side device configures the transmission timing and period of the LP - target signal, the transmission timing of the LP - target signal can be configured relative to the LP - SS, and the period of the LP - target signal can be an integer multiple of the SSB period. Then the position of the LP - target signal transmission timing relative to the SSB is fixed. Similarly, for the LP - SS, the above - mentioned configuration of the LP - target signal can be referred to.

[0145] Optionally, in some embodiments, the method further includes:

Similarly, the above - mentioned specific time offset can be a preset time offset or a time offset determined according to the time - domain position of the LP - SS or the transmission position of the target signal.

[0148] For example, the network - side device configures the specific time window or offset relative to the LP - SS or the LP - target signal, and after the terminal sends the target signal, it detects the target transmission within the specific time window or after the specific time offset.

[0149] 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 for detecting the target transmission or the terminal starts caching data for T time periods after the specific offset for detecting the target transmission.

[0150] Optionally, T is configured by the network - side, or agreed upon by the protocol, or indicated by the LP - SS.

[0151] Optionally, T is less than or equal to the period of the target transmission.

[0152] Optionally, in some embodiments, after the terminal sends the target signal, it performs a first operation within a specific time window or after a specific time offset.

[0153] Optionally, in some embodiments, after the terminal sends a target signal to the network - side device according to the LP - SS, the method further includes at least one of the following:

[0154] In the case where the terminal does not detect the target transmission and the number of times of sending the target signal is less than the first preset number of times, the terminal sends the target signal again;

[0155] In the case that the terminal does not detect 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;

[0156] Wherein, the second operation includes at least one of the following:

[0158] Switch to other frequency positions or other cells on the same frequency to perform cell search or initial access based on LP-SS;

[0160] In the embodiments of the present application, performing cell search or initial access based on SSB can be understood as directly performing cell search or initial access based on SSB without performing cell handover.

[0161] Switching to other frequency positions or other cells on the same frequency can be understood as performing cell handover. Specifically, the terminal can directly perform cell search or initial access based on LP-SS or SSB on the cell after the handover.

[0162] In the embodiments of the present application, if no SSB is 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.

[0163] Optionally, in some embodiments, after the terminal sends a target signal to the network-side device according to the LP-SS, the method further includes:

[0164] The terminal listens for first information, and the first information is an acknowledgement message of the target signal.

[0165] In the embodiments of the present application, after receiving the target signal, the network-side device can send first information to the terminal based on the target signal.

[0166] Optionally, in some embodiments, after the terminal listens for the first information, the method further includes at least one of the following:

[0167] In the case that the terminal does not detect the first information and the number of times the terminal sends the target signal is less than a second preset number of times, the terminal sends the target signal again;

[0168] In the case that 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 the second preset number of times, the terminal performs the second operation;

[0169] Among them, the second operation includes at least one of the following:

[0170] Performing cell search or initial access based on the SSB;

[0171] Switching to other frequency positions or other cells on the same frequency to perform cell search or initial access based on the LP-SS;

[0172] Switching to other frequency positions or other cells on the same frequency to perform cell search or initial access based on the SSB.

[0173] In the embodiments of the present application, when the terminal receives the first information, it can start listening for the target transmission. When the terminal does not receive the first information, it can resend the target signal until the maximum number of transmissions N is reached. If the terminal still does not detect the first information after sending the target signal up to the maximum number N times, it can trigger the execution of the second operation.

[0174] Optionally, in some embodiments, the first information is used to indicate the relevant information of the target transmission.

[0175] Optionally, in some embodiments, the relevant information of the target transmission includes at least one of the following:

[0181] Optionally, the above time-frequency domain position information of the target transmission can be understood as being configured relative to the LP-SS or relative to the first information. For example, configuring the time offset of the target transmission relative to the LP-SS or the time-frequency domain position information of the listening time window.

[0182] Optionally, the above time offset of the target transmission can be understood as being configured relative to the LP-SS or relative to the first information.

[0229] Wherein, the third operation includes at least one of the following: cell search and initial access.

[0230] In the embodiments of the present application, the above frequency position may be understood or replaced by a frequency point.

[0231] Optionally, when the measurement result of the LP-SS is lower than a preset threshold, the terminal can turn on the primary receiver and fallback 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 on the same frequency) to perform cell search or initial access using SSB or LP-SS.

[0232] To better understand the present application, the following will be described by way of some examples.

[0233] In some embodiments, the following process steps may be included:

[0234] Step 11, the terminal detects the LP-SS.

[0235] In one example, the terminal can obtain rough time-frequency synchronization information through the LP-SS (rough means relative to the terminal directly obtaining time-frequency synchronization information 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 specifically obtains rough time-frequency synchronization information through detecting the LP-SS is not limited herein. In addition, it can be understood that the terminal can assist the subsequent detection of SSB through the detection of LP-SS. Specifically, the terminal obtains time-frequency domain information through the LP-SS, which can be used to narrow the detection range of the time-frequency domain position 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.

[0236] Optionally, information such as the detection timing, period, LP-SS sequence, and modulation and coding method of the LP-SS can be configured in a protocol-agreed manner.

[0237] Step 12, the terminal detects the SSB according to the detection of the LP-SS, or the terminal determines whether the network-side device has enabled the target transmission according to the detection of the LP-SS. (For example, the LP-SS carries an indication of whether the target transmission is enabled or makes an implicit indication through different LP-SS sequences).

[0238] Optionally, when the terminal does not detect the SSB, the terminal sends a WUS to trigger the network-side device to perform the target transmission.

[0239] Optionally, when the terminal detects the SSB, the terminal does not send a WUS.

[0240] 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.

[0241] Optionally, when it is determined that the network-side device has enabled the target transmission, the terminal does not send a WUS.

[0242] It should be understood that if SSB transmission has been resumed or started before the terminal enters the cell, the terminal does not need to send WUS to trigger SSB, which can save uplink resources and avoid WUS transmission conflicts between multiple UEs.

[0243] In one example, when the terminal detects the LP-SS and has a need for cell search, initial access, cell residence, etc., the terminal can trigger the network-side device to perform target transmission by sending WUS.

[0244] It can be understood that before the terminal sends WUS, that is, during the LP-SS detection process, the terminal assumes that the network-side device does not send target transmission.

[0245] In one example, before step 12, that is, before the terminal sends WUS, it is necessary to obtain the configuration information of WUS and determine the candidate transmission timing of WUS. The terminal sends WUS at the candidate WUS transmission timing.

[0246] Optionally, the terminal can obtain the configuration information of WUS through at least one of protocol agreement and network indication.

[0247] Method 1: The terminal obtains the configuration information of WUS through LP-SS, that is, the LP-SS carries the indication information of the WUS configuration.

[0248] Method 2: The terminal obtains the configuration information of WUS through LP-SS and protocol agreement.

[0249] In one example, LP-SS carrying and protocol agreement can each indicate part of the WUS configuration information. For example, LP-SS bears the indication of the WUS transmission timing, and the protocol agreement specifies the number of WUS transmission timings, the transmission period of WUS, the time interval between each WUS transmission timing, the frequency domain position where WUS is located, etc.

[0250] In one example, the protocol agrees on a WUS configuration table, which contains many configuration parameters of WUS. Each row of the table is a set of WUS configurations. The LP-SS carries an indication of the table row index to indicate which set of WUS configurations to apply.

[0251] Optionally, after the terminal sends WUS, the following steps 13a or 13b can be executed.

[0252] Step 13a, the terminal listens for the first information sent by the network-side device, and the first information is the confirmation information sent by the network-side device after receiving WUS.

[0253] Optionally, when the terminal receives the first information, it starts listening for the target transmission. That is, if the terminal does not receive the first information, it does not start listening for the target transmission.

[0254] Step 13b, the terminal listens for the target transmission.

[0255] Optionally, the terminal detects the target transmission within a specific time range or a specific time window or after a specific time offset.

[0256] Optionally, the time offset can be understood as the distance between the LP-SS and the nearest target transmission. For example, as Figure 3 the relative offset in

[0257] In one example, there is a multiple relationship between the period of the LP-SS and the period of the SSB (target transmission). And the starting offset of the LP-SS (such as Figure 3 the offset 1 in Figure 3 and the starting offset of the SSB (such as Figure 3 the offset 2 in

[0258] are configured by the network side or agreed upon by the protocol. As shown in Figure 3

[0259]

[0260]

[0261] In one example, if the terminal does not detect the SSB or does not detect the first information within a specific time interval after sending the WUS, the terminal sends the WUS again. Optionally, the maximum number of times the WUS can be sent is configured by the network side or agreed upon by the protocol, or indicated by the LP-SS.​​Optionally, LP-SS can be used to assist SSB in performing initial 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 position information where the SSB is located, and the period of the SSB, etc.

[0262] In addition, it should be noted that the detection of LP-SS can also help the terminal to send UL WUS information.

[0263] Optionally, the transmission timing of WUS can also be referred to as the time-frequency position when WUS is transmitted.

[0264] In one example, the transmission timing of WUS is at any time position. At this time, for the network side device, the base station needs to continuously monitor the WUS transmitted by the terminal in the time domain;

[0265] In one example, the transmission timing of WUS is determined relative to the time-frequency domain position of LP-SS; for example, the starting position of the transmission timing of WUS is a specific time offset or a specific time interval from the starting or ending position of LP-SS.

[0266] For example, LP-SS carries the transmission timing indication information of WUS, and this indication information indicates the time offset of WUS relative to LP-SS. In addition, within one LP-SS period, the protocol stipulates or LP-SS indicates multiple WUS candidate transmission timings. As Figure 4 shown, there are 3 WUS occasions within each LP-SS period. The interval size of each WUS occasion can be stipulated. LP-SS carries the time offset indication of UL WUS relative to LP-SS.

[0267] Optionally, in one example, the time domain synchronization of WUS transmission refers to the timing of the base station of other cells or Radio Access Technology (RAT), and WUS is transmitted at a specific time domain position based on this.

[0268] In one example, for the network side device, the protocol pre-defines or the base station configures or LP-SS indicates exactly the same WUS configuration information to some or all terminals.

[0269] It should be understood that in the above embodiments, LP-SS can indicate the relative offset of the target transmission, and can also indicate the relative offset of the WUS transmission timing. That is to say, when the terminal sends WUS, it can determine the position information of the target transmission relative to WUS according to the above two relative offsets.

[0270] Optionally, the waveform or modulation method of WUS.

[0271] In one example, the WUS is generated based on an OOK waveform or modulation method, including but not limited to OOK-1, OOK-2, OOK-4, etc.;

[0272] In one example, the WUS is generated based on an OFDM waveform or modulation method, including but not limited to OFDM, DFT-s-OFDM, MB-OFDM, F-OFDM, etc.;

[0273] 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.;

[0274] In one example, the WUS is generated based on an FSK waveform or modulation method, including but not limited to 2FSK, 4FSK, etc.

[0275] Optionally, the repetition of the WUS.

[0276] In one example, the WUS is repeatedly transmitted L times in the time domain, and the content and transmission method of the L transmissions are the same (e.g., omnidirectional transmission);

[0277] In one example, the WUS is repeatedly transmitted L times in the time domain, the content of the L transmissions is the same, and the transmission method is to transmit through different beam directions;

[0278] In one example, the WUS is repeatedly transmitted L times in the time domain, the indexes of the L transmissions are different (other contents are the same), and the transmission method is to transmit through different beam directions;

[0279] In one example, the WUS is repeatedly transmitted P times in the frequency domain.

[0280] In one example, if the SSB is not detected within a specific time period after the WUS is transmitted, the terminal retransmits the WUS until the maximum number of transmissions N.

[0281] If the terminal still does not detect the SSB after transmitting the WUS up to the maximum number of times N, it performs cell search based on LP-SS or starts to perform cell search based on SSB.

[0282] In one example, after transmitting the WUS, the terminal listens for the first piece of information, which is the confirmation information received by the network side for the WUS transmission.

[0283] Further, when the terminal receives this first piece of information, it starts to listen for the target transmission.

[0284] In one example, when the terminal does not receive the first piece of information, the terminal retransmits the WUS until the maximum number of transmissions M.

[0285] If the terminal still does not detect the SSB after sending the WUS for the maximum number of times M, it re-performs cell search based on the LP-SS or starts cell search based on the SSB.

[0286] Furthermore, the first information indicates the relevant information of the target transmission. For example, the relevant information of the target transmission includes the time-frequency domain position information of the SSB (relative to the time-frequency domain position of the LP-SS or the first information).

[0287] Optionally, the transmission condition of the WUS may include at least one of the following:

[0288] Ready to perform initial access;

[0289] Ready to perform initial access on the frequency band where WUS triggering is possible;

[0290] Cell search is performed on the frequency band supported by the terminal and no SSB is detected;

[0291] Cell search is performed on the frequency band supported by the terminal where WUS triggering is not possible and no SSB is detected;

[0292] No SSB is detected after the terminal performs cell search for a period of time T;

[0293] The terminal experiences a radio link failure;

[0294] The terminal performs radio link recovery.

[0295] It should be noted that since the transmission timing of the WUS is broadcast, that is, the network-side device configures the transmission timing of the WUS for all terminals in the cell, it is possible that multiple terminals select the same WUS transmission timing to send the WUS, resulting in a collision.

[0296] To further reduce the collision. One method is for the network-side device to configure more WUS transmission timings, and the terminal randomly selects a WUS transmission timing to send. Another method is for the protocol to stipulate the corresponding relationship between the WUS transmission timings configured by the network-side device and the terminal, so as to evenly distribute different UEs to different WUS transmission timings, achieving the effect of terminal grouping.

[0297] Another method can also be adopted to reduce the probability that the network-side device cannot demodulate when multiple terminals send the WUS simultaneously. For example, design a sequence with better autocorrelation or cross-correlation to combat interference (interference from neighboring cells or multi-user interference) and improve the demodulation performance.

[0298] Optionally, the network-side device may configure a pool of WUS sequences, which contains multiple WUS sequences. The terminal randomly or in a certain manner selects a WUS sequence from it and then performs WUS transmission. The orthogonality between different WUS sequences is relatively high or the correlation is very low. In this way, different UEs can be distinguished, thereby reducing the probability of collision.

[0299] LP-SS measurement fallback.

[0300] In one example, when the measurement result of the LP-SS is lower than a specific threshold (including the case where the LP-SS cannot be detected), the terminal (turns on the main receiver) falls back to the state of using the SSB for cell search or initial access, or the terminal switches to another cell (a cell corresponding to another frequency position or another cell on the same frequency) for cell search or initial access.

[0301] Referring to Figure 5 , the embodiment of the present application also provides a transmission processing method, as Figure 5 shown, the transmission processing method includes:

[0302] Step 501, the network-side device sends a low-power synchronization signal LP-SS;

[0303] Step 502, the network-side device receives a target signal from the terminal;

[0304] Step 503, the network-side device performs target transmission according to the target signal;

[0309] In the embodiment of the present application, the above target signal is triggered based on the above LP-SS.

[0310] Optionally, the LP-SS satisfies at least one of the following:

[0311] There is a time-frequency domain association relationship between the LP-SS and the target transmission, or the LP-SS indicates the relevant parameters of the target transmission;

[0312] Different sequences of the LP-SS are respectively associated with whether the network-side device starts the target transmission, or the LP-SS indicates whether the network-side device turns on the target transmission;

[0313] 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 indicates whether the network-side device performs the target transmission according to the target transmission period.

[0317] Optionally, after the network-side device performs target transmission according to the target signal, the method includes:

[0318] The network-side device sends first information to the terminal, and the first information is a confirmation message of the target signal.
