Description

Signal processing method and device

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on December 7, 2023, with application number 202311674747.0 and application name “Signal Processing Method and Device,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to a signal processing method and device. Background Art

[0003] Network energy conservation is crucial for environmental sustainability, reducing environmental impact (greenhouse gas emissions), and saving operating costs. Base stations can employ certain energy-saving measures, such as hibernation or stopping signal transmission and reception. However, since terminals are unaware of when the base station enters this energy-saving state, they assume the base station is always providing service. If the base station cannot be awakened or powered on, terminal services are impacted. Summary of the Invention

The indication information is used to indicate that the first signal is used for at least one of the following: discovering a terminal; waking up a target cell; triggering the target cell to send and / or receive a first object; or triggering the target cell to switch to the first state.

[0214] The OOK / ASK / FSK / PSK signal is a low-power signal. The network-side equipment corresponding to the target cell can detect and process the OOK / ASK / FSK / PSK signal through envelope detection. This low-power signal enables the terminal to communicate with a dormant cell or a cell in an energy-saving state without synchronization, thereby waking up the dormant cell or triggering the dormant cell to wake up and provide service.

[0215] In an embodiment of the present disclosure, the terminal sends a first signal, and the first signal includes at least one of the following: an OOK signal; an ASK signal; an FSK signal; a PSK signal. The OOK / ASK / FSK / PSK signal can be used to wake up the target cell, trigger the target cell to send and / or receive the first object, and trigger the target cell to switch to the first state. Since the signal transmitted between the terminal and the network side device in the related technical solution is an OFDM signal, and the network side device in the sleep or energy-saving state cannot process the OFDM signal (such as fast Fourier transform FFT), and the above-mentioned OOK / ASK / FSK / PSK signal is a low-power signal different from the OFDM signal, the processing method of the low-power signal is different from the processing method of the OFDM signal in the related technology. The cell in the sleep state or energy-saving state can process the low-power signal, so that the terminal can communicate with the sleep cell or the cell in the energy-saving state without synchronization through the low-power signal, thereby achieving the purpose of waking up the sleep cell or triggering the sleep cell to wake up and provide services.

[0216] In some embodiments, the first signal is a signal based on Orthogonal Frequency Division Multiplexing (OFDM), that is, the first signal is an OFDM-based OOK / ASK / FSK / PSK signal.

[0217] When the first signal is an OOK / ASK / FSK / PSK signal based on OFDM, the architecture of the New Radio (NR) transceiver in the relevant technology can be used to further avoid adding new transceivers, thereby simplifying the complexity of the transceiver. The detection of OOK / ASK / FSK / PSK modulated signals (i.e., OOK / ASK / FSK / PSK signals based on OFDM) can greatly reduce the power consumption of the receiving end because it does not require an inverse Fourier transform (IFFT) operation to perform envelope, filtering or phase detection, thereby achieving energy saving.

[0218] In some embodiments, the first signal carries at least one of the following:

[0219] Discover terminal related information, for example, information such as amplitude / phase / power / energy of a signal used for signal detection;

[0220] Information related to waking up the target cell, for example, includes indication information for waking up the target cell or the cell group where the target cell is located and information related to the identifier of the target cell or the cell group where the target cell is located, where the indication information for waking up the target cell is used to indicate whether to wake up the target cell;

[0221] Information related to the triggered target cell, for example, including indication information of the target cell or the cell group to which the target cell belongs and information related to the identifier of the target cell or the cell group to which the target cell belongs. The triggered target cell indication signal is used to indicate the target cell to be triggered;

[0222] Relevant information for triggering the target cell to send and / or receive the first object, for example, including first target reference signal sending and / or receiving indication information, where the indication information is used to indicate at least one of the first target reference signal and the first target channel to be sent or received by the target cell;

[0223] The relevant information for triggering the target cell to switch to the first state includes, for example, cell state indication information.

[0224] As an implementation manner, the first signal carries at least one of the following:

[0225] Wake-up cell indication information, used to indicate whether to wake up the target cell;

[0226] Cell identity related information, used to indicate relevant cell information for sending / receiving a wake-up or triggering signal / channel;

[0227] First object sending / receiving indication information, used to indicate the first object sent / received by the target cell;

[0228] Function trigger indication information is used to instruct the target cell to enable or disable specific functions, such as measurement, synchronization, positioning, energy saving, access, and specific service transmission;

[0229] Terminal specific identifier, used to indicate the specific type or terminal identifier of the terminal, such as terminal type identifier, terminal version identifier, terminal identifier supporting specific services, and related indications of whether the target cell can be woken up;

[0230] Terminal demand information related identifiers are used to indicate the current service requirements of the terminal, such as access, measurement, synchronization, positioning, energy saving, and specific service transmission requirements; or, to indicate the current service requirements of the terminal, such as enhanced mobile broadband (eMBB) services, extended reality (XR) services, ultra-reliable and low latitude communications (URLLC) services, massive machine type communication (mMTC) services, and ambient internet of things (AIoT) services.

[0231] The cell state indication information is used to instruct the target cell to switch between at least two states, or to switch to the first state.

[0232] In an embodiment of the present disclosure, the network side device can wake up the target cell after receiving the above-mentioned first signal for a certain period of time; trigger the target cell to send and / or receive the first object; trigger the target cell to switch to at least one of the first state.

[0233] When the terminal does not receive any synchronization signal sent by the target cell, such as the primary synchronization signal (PSS), the secondary synchronization signal (SSS), the synchronization signal / physical broadcast channel signal block (SSB), the tracking reference signal (TRS), etc., or when the synchronization signal sent by the target cell is received at a longer time interval, such as PSS, SSS, SSB, TRS, etc., the terminal cannot achieve synchronization or fine synchronization with the base station, and the terminal cannot send any signal to the base station based on the NR signal in the related technology. In the embodiment of the present disclosure, the terminal sends a first signal, which is a modulated signal based on OOK / ASK / FSK / PSK. There is no need for precise synchronization between the base station and the terminal. The first signal can be detected based on the amplitude / power / energy / phase and other related information of the first signal, that is, the effect of detecting the terminal without precise synchronization is achieved.

[0234] In some embodiments, the first signal may also jointly indicate at least one of waking up the target cell, triggering the target cell to send and / or receive the first object, and triggering the target cell to switch to the first state. That is, when the base station detects the first signal of the terminal, it may wake up the target cell, trigger the target cell to send and / or receive the first object, and trigger the target cell to switch to the first state. The specific joint indication may be defined by the protocol and determined by at least one of the following: terminal pre-stored information, core network information, and terminal historical information.

[0235] In some embodiments, when the terminal can achieve coarse synchronization with the base station, the first signal can further carry at least one indication information such as waking up the target cell; triggering the target cell to send and / or receive the first object; triggering the target cell to switch to the first state. For example, when the first signal is a different time domain or frequency domain sequence pattern, it corresponds to different indication information. When the base station detects that the first signal is a specific time domain or frequency domain sequence pattern, it obtains the corresponding indication information, and then sends and / or receives at least one of a specific reference signal and a specific channel. In this way, the base station does not need to continuously send a synchronization signal for fine synchronization to the terminal, such as an SSB with a period of less than or equal to 160ms, that is, when the base station achieves energy saving on the network side, it can also be awakened according to the terminal service needs, or triggered to send and / or receive the first object, or switch to the transmission and reception of signals / channels in different energy-saving states, so as not to affect the business service needs of the terminal.

[0236] When the first signal implicitly or explicitly triggers the target cell to send and / or receive the first object, at least one of the specific reference signal and the specific channel can be triggered in a targeted manner. For example: according to service requirements, the terminal needs to trigger the target cell to send SSB and / or tracking reference signal (Tracking Reference Signal, TRS) for synchronization service, and the target cell needs to send positioning reference signal (Positioning Reference Signal, PRS) and / or receive sounding reference signal (SRS) for positioning service. The measurement needs to trigger the target cell to send SSB and / or CSI reference signal (CSI Reference Signal, CSI-RS). Access requires sending SSB, sending random access preamble (preamble) and receiving physical random access channel (Physical Random-Access Channel, PRACH) and at least one other item. The base station only needs to send and / or receive the above-mentioned reference signal and / or channel according to the first signal, and does not need to send and / or receive all reference signals and channels, thereby achieving energy saving on the network side.

[0237] When the first signal implicitly or explicitly triggers the target cell to switch to the first state, here, the first state can be one of at least one cell state, or different cell states corresponding to different parameter configuration sets. Here, the cell state can be a cell energy-saving state, or a cell providing different service states. For example: the terminal can select a cell based on its business needs, such as: the terminal only needs to perform radio resource management (RRM) measurements. At this time, the target cell only needs to be in a light sleep state and send SSB or CSI-RS with a period of 80ms. The base station only needs to trigger the reference signal / channel sending / receiving in the light sleep state according to the first signal, so as to achieve energy saving of the base station while meeting the business needs of the terminal.

[0238] In some embodiments, the method of the present disclosure further includes:

[0239] A first response signal to the first signal is acquired.

[0240] In the disclosed embodiment, the base station detects the first signal and, if signal information of the first signal satisfies a first condition, sends a first response signal to the first signal. For example, the base station sends the first response signal when the signal information of the first signal satisfies a specific threshold or a specific value.

[0241] In some embodiments, the first response signal carries at least one of the following:

[0242] Confirmation information of the first signal; the confirmation information may be an OOK / ASK / FSK / PSK signal, for example, an OFDM-based OOK / ASK / FSK / PSK signal;

[0243] Feedback information on the first signal; the feedback information may be an OOK / ASK / FSK / PSK signal, for example, an OFDM-based OOK / ASK / FSK / PSK signal;

[0244] The first reference signal and / or the first channel; the first reference signal is used as a reference signal for whether the subsequent terminal wakes up the dormant cell or provides a reference signal for a specific function for the terminal. For example, the specific function may be synchronization, measurement or positioning functions. The reference signal may be PSS, SSS, SSB, CSI-RS, TRS, PRS, PTRS, etc. The first channel includes a downlink control channel, an uplink control channel, PBCH, PRACH, etc.

[0245] Cell information of the cell that sends the first response signal, such as cell identification information.

[0246] In some embodiments, the first response signal may be sent by at least one base station that receives the first signal.

[0247] For feedback information or confirmation information of the first response signal being the first signal, in order to prevent the base station from being awakened by each terminal of the first signal, or being triggered to send / receive signals, or being triggered to switch to the first state of the cell, thereby affecting the energy saving gain of the base station. After detecting the first signal, the base station can determine whether to be awakened, or triggered to send / receive signals, or triggered to switch to the first state of the cell for confirmation or feedback based on the internal implementation algorithm, and further instruct the terminal whether to wake up the cell, or whether to trigger sending / receiving signals, or whether to trigger switching to the first state of the cell, or whether to receive the first signal. On the one hand, it reduces the base station from being awakened unconditionally, and on the other hand, it reduces the terminal from continuously sending the first signal, so that both parties understand each other.

[0248] If the first response signal is a first reference signal and / or a first channel, for example, after detecting the first signal, the base station transmits the first reference signal, such as the PSS, SSS, TRS, or SSB, and receives the PRACH channel and the PDCCH on which paging is located. These signals can be used by the terminal for subsequent communication activities, such as synchronization, RRM measurement, cell access, random access, and paging. The terminal receives and / or transmits the first reference signal and / or the first channel at specific intervals after transmitting the first signal. After receiving the response signal from at least one cell, the terminal selects a target cell to provide service to the terminal through a specific algorithm, such as a cell selection process. If no terminal accesses the other cells that sent the response signal within a specific time period, the terminal may enter a dormant state. If the terminal receives the response signal from only one cell, the current cell is selected as the target cell, and the terminal accesses the target cell. This method eliminates the need for cells to remain in service, thereby reducing network-side energy consumption. Alternatively, the terminal can access the target cell by detecting the first reference signal and / or first channel transmitted / received by the target cell to obtain the target cell's services, thereby reducing the impact on service performance.

[0249] In addition, the terminal can also achieve synchronization with the network side by receiving the first response signal, and further send signals to the target cell to provide the prerequisite for sending and receiving at least one of the target reference signal, target channel, sending target indication information, and the second signal triggered by it, that is: the sending and receiving parties are synchronized.

[0250] In some embodiments, the method of the present disclosure further includes:

[0251] A second signal is sent to a specific cell, where the second signal is used to indicate at least one of the following: waking up the specific cell; triggering the specific cell to send or receive a second object; triggering the specific cell to switch to a second state, wherein the second object includes at least one of a second target reference signal and a second target channel.

[0252] In some embodiments, the above-mentioned second target reference signal includes at least one of the following: primary synchronization signal (PSS), secondary synchronization signal (SSS), synchronization signal / physical broadcast channel signal block (SSB), TRS, positioning reference signal (PRS), phase tracking reference signal (PT-RS), random access preamble code, sounding reference signal (SRS), demodulation reference signal (DMRS), CSI reference signal (CSI-RS).

[0253] In some embodiments, the second target channel includes at least one of the following: physical uplink control channel (PUCCH), physical downlink control channel (PDCCH), physical broadcast channel (PBCH), physical random access channel (PRACH), physical sidelink shared channel (PSSCH), physical downlink shared channel (PDSCH), and physical uplink shared channel (PUSCH).

[0254] In an embodiment of the present disclosure, the terminal may determine, based on the first response signal, to which target cell to send the second signal. That is, the specific cell is one or more cells among the target cells. Specifically, the terminal may randomly determine one or more cells (i.e., the specific cells) among the target cells that sent the first response signal, or may determine one or more cells (i.e., the specific cells) among the target cells that sent the first response signal in other ways.

[0255] In some embodiments, the second signal carries at least one of the following:

[0256] Wake up the relevant information of a specific cell;

[0257] Triggering specific cell related information;

[0258] triggering a specific cell to send and / or receive relevant information of a second object;

[0259] Relevant information for triggering a specific cell to switch to the second state.

[0260] As an implementation manner, the second signal carries at least one of the following:

[0261] Cell wake-up indication information, used to indicate whether to wake up a specific cell;

[0262] Cell identity related information, used to indicate relevant cell information for sending / receiving a wake-up or triggering signal / channel;

[0263] Second object sending / receiving indication information, used to indicate the second object sent / received by a specific cell;

[0264] Function trigger indication information is used to instruct a specific cell to enable or disable specific functions, such as measurement, synchronization, positioning, energy saving, access, and specific service transmission;

[0265] Terminal specific identifier, used to indicate the specific type or terminal identifier of the terminal, such as terminal type identifier, terminal version identifier, terminal identifier supporting specific services, and related indications of whether the target cell can be woken up;

[0266] Terminal demand information related identifiers are used to indicate the current service requirements of the terminal, such as access, measurement, synchronization, positioning, energy saving, and specific service transmission requirements; or indicate the current service requirements of the terminal, such as eMBB service, XR service, URLLC service, mMTC service, AIoT service, etc.

[0267] The cell state indication information is used to instruct a specific cell to switch between at least two states, or to switch to a second state.

[0268] When the terminal sends the first signal, it may also send a second signal to further provide the base station with additional information. The additional information includes at least one of the following: enhanced or supplementary information of the first signal, i.e., information that improves the reception performance of the first signal, or provides supplementary information of the first signal.

[0269] For information about the second signal used to improve reception performance of the first signal, such as when the second signal is a duplicate of the first signal or carries information related to the first signal, but the first and second signals are different signals, the terminal sending the second signal can improve the base station's ability to discover the terminal and obtain information carried by the first and / or second signals.

[0270] The second signal is used to provide supplementary information about the first signal. For example, the first signal is transmitted based on a broadcast when the terminal and the base station are not synchronized or precisely synchronized, and serves as a signal for the base station to discover the terminal. The second signal can be sent as supplementary information for the terminal, such as the terminal version or terminal type, to enable the discovery of a target cell that can serve the terminal. After the base station detects the first signal, it detects the second signal. If the cell can provide service to the terminal, the cell is awakened as the target cell and triggered to send or receive the second object, triggering the switching to at least one of the second states. In this way, by sending the second signal, the accuracy of waking up or triggering the target cell can be improved, thereby improving network energy saving performance.

[0271] After receiving the first response signal, the terminal transmits a second signal to further instruct the target cell to wake up, trigger the target cell to send or receive a second object, and trigger the target cell to switch to at least one of the second states. Upon receiving the first response signal, such as for synchronization signals PSS, SSS, TRS, SSB, etc., the terminal can synchronize with the base station. The terminal can transmit the second signal, which carries indication information for the target cell, to wake up the target cell, trigger the target cell to send or receive a second object, and trigger the target cell to switch to at least one of the second states. The target cell can provide a specific indication via the second signal, or an implicit indication via a second signal that has a specific correlation with the response signal sent by the target cell. The target cell can transmit a synchronization signal based on the terminal's service needs to obtain more precise indication information, such as indication information related to being woken up by the terminal, indication information related to triggering the sending or receiving of the second object, or indication information related to triggering switching to a specific cell state, without having to constantly provide synchronization signals with the terminal, thereby achieving network-side energy conservation.

[0272] In some embodiments, the second signal may also jointly indicate at least one of waking up a specific cell, triggering the specific cell to send and / or receive a second object, and triggering the specific cell to switch to a second state. That is, when the base station detects the second signal from the terminal, it may wake up the specific cell, trigger the specific cell to send and / or receive a second object, and trigger the specific cell to switch to the second state. The specific joint indication may be defined by the protocol and determined by at least one of terminal pre-stored information, core network information, and terminal historical information.

[0273] In some embodiments, when the terminal can achieve coarse synchronization with the base station, the second signal can further carry indication information of at least one of waking up a specific cell; triggering a specific cell to send and / or receive a second object; and triggering a specific cell to switch to a second state. For example, when the second signal is a different time domain or frequency domain sequence pattern, it corresponds to different indication information. When the base station detects that the second signal is a specific time domain or frequency domain sequence pattern, it obtains the corresponding indication information, and then sends and / or receives at least one of a specific reference signal and a specific channel. In this way, the base station does not need to continuously send a synchronization signal for fine synchronization to the terminal, such as an SSB with a period of less than or equal to 160ms, that is, when the base station achieves energy saving on the network side, it can also be awakened according to the terminal service needs, or triggered to send and / or receive the second object, or switch to the transmission and reception of signals / channels in different energy-saving states, so as not to affect the business service needs of the terminal.

[0274] When the second signal implicitly or explicitly triggers a specific cell to send and / or receive a second object, at least one of a specific reference signal and a specific channel can be triggered in a targeted manner. For example: according to service requirements, the terminal needs to trigger the target cell to send SSB and / or tracking reference signal (TRS) for synchronization service, and the target cell needs to send positioning reference signal (PRS) and / or receive sounding reference signal (SRS) for positioning service. The measurement needs to trigger the target cell to send SSB and / or CSI reference signal (CSI Reference Signal, CSI-RS). Access requires sending SSB, sending random access preamble (preamble) and receiving physical random access channel (PRACH) and at least one of the above. The base station only needs to send and / or receive the above reference signals and / or channels according to the second signal, and does not need to send and / or receive all reference signals and channels, thereby achieving energy saving on the network side.

[0275] When the second signal implicitly or explicitly triggers the target cell to switch to the second state, here, the second state can be one of at least one cell state, or different cell states corresponding to different parameter configuration sets. Here, the cell state can be a cell energy-saving state, or a cell providing different service states. For example: the terminal can select a cell based on its business needs, such as: the terminal only needs to perform RRM measurement to select a cell. At this time, the target cell only needs to be in a light sleep state and send SSB or CSI-RS with a period of 80ms. The base station only needs to trigger the reference signal / channel sending / receiving in the light sleep state according to the second signal, so as to achieve energy saving of the base station while meeting the business needs of the terminal.

[0276] In some embodiments, the method of the present disclosure further includes:

[0277] A second response signal is acquired, where the second response signal is a response signal to a target signal, and the target signal includes the second signal, or includes the first signal and the second signal.

[0278] In the embodiment of the present disclosure, the base station may send a first response signal after receiving the first signal and send a second response signal after receiving the second signal, or may send the above-mentioned second response signal after receiving the first signal and the second signal.

[0279] In some embodiments, the second response signal carries at least one of the following:

[0280] Confirmation information of the target signal; the confirmation information may be an OOK / ASK / FSK / PSK signal, for example, an OFDM-based OOK / ASK / FSK / PSK signal;

[0281] Feedback information of the target signal; the feedback information may be an OOK / ASK / FSK / PSK signal, for example, an OFDM-based OOK / ASK / FSK / PSK signal;

[0282] A second reference signal or a second channel; the second reference signal is used as a reference signal for whether a subsequent terminal wakes up a dormant cell or provides a reference signal for a specific function for the terminal. For example, the specific function may be synchronization, measurement or positioning functions. The reference signal may be SSB, CSI-RS, TRS, random access preamble, etc. The second channel includes a downlink control channel and / or an uplink control channel.

[0283] Cell information of the cell that sends the second response signal, such as cell identification information.

[0284] In some embodiments, the second response signal may be sent by the target cell that receives the second signal.

[0285] For feedback information or confirmation information of the second response signal being the second signal, in order to avoid the base station being awakened by each terminal of the second signal, or being triggered to send and / or receive signals, or being triggered to switch to the second state of the cell, affecting the energy saving gain of the base station. After the base station detects the second signal, it can determine whether to be awakened according to the internal implementation algorithm, or be clearly indicated by the second signal whether to be awakened, or be triggered to send / receive signals, or be triggered to switch to the second state of the cell for confirmation or feedback, and further instruct the terminal whether to wake up the cell, or whether to trigger sending / receiving signals, or whether to trigger switching to the second state of the cell, or whether to receive the second signal. On the one hand, it reduces the base station from being awakened unconditionally, and on the other hand, it responds to the second signal sent by the terminal, so that both parties understand each other.

[0286] The second response signal is a second reference signal and / or a second channel. For example, after the base station detects the second signal, it sends a second reference signal, such as PSS, SSS, TRS, SSB, etc., and receives the channel PRACH, PDCCH where Paging is located, etc., which can be used by the terminal to perform at least one of subsequent synchronization, RRM measurement, cell access, random access and paging. The terminal receives / sends the second reference signal and / or the second channel in a specific time period after receiving the second response signal. After receiving the response signal, the target cell provides service to the terminal. The cell that does not send the second response signal cannot be accessed by the terminal within a specific time period, and the cell enters a dormant state and does not need to be in a service state all the time, thereby reducing energy consumption on the network side.

[0287] In some embodiments, the method of the present disclosure further includes:

[0288] At a first moment, receiving and / or sending a first specific reference signal and / or a first specific channel in an RRC idle state or an RRC inactive state in a first specific cell;

[0305] In some embodiments, the method of the present disclosure further includes:

[0306] At a second moment, sending and / or receiving a second specific reference signal and / or a second specific channel of a second specific cell;

[0307] The second moment includes at least one of the following:

[0311] a moment that is separated by a fourth time period from a moment of receiving the second response signal, the second response signal being a response signal to the second signal, or a response signal to the first signal and the second signal;

[0334] It should be noted that the third moment, the second moment and the first moment in the embodiment of the present disclosure may be the same or different.

[0335] The following describes the method for generating OOK / ASK / FSK / PSK signals in conjunction with Example 1.

[0336] Example 1: Method for generating OOK / ASK / FSK / PSK signals based on OFDM;

[0337] As shown in Figures 3 and 4, the transmitter for sending the first signal and / or the second signal by the terminal can be a transmitter independent of the transmitter of the uplink NR signal, or can be the same transmitter.

[0338] The receiver of the base station for receiving the first signal and / or the second signal can be a receiver independent of the receiver of the uplink NR signal, or can be the same receiver.

[0339] The following describes how to generate a signal based on Multi Carrier Amplitude Shift Keying (MC-ASK), such as an OFDM-based On-Off Keying (OOK):

[0340] Based on the number of ASK bits and the frequency domain resources / Inverse Fast Fourier Transform (IFFT) points occupied by each bit, MC-ASK waveform generation can include the following four optional waveform generation methods:

[0341] Method 1:

[0342] OOK-1: As shown in Figure 5, the Low Power Wake Up Signal (LP-WUS) includes N subcarriers (SC). After the LP-WUS is subjected to an inverse fast Fourier transform (IFFT) and a cyclic prefix (CP) is added, one OFDM symbol corresponds to a single bit.

[0343] The subcarrier (SC) of the low power wake-up signal (LP-WUS) is:

[0344] OOK=1 means that all SCs are used for modulation, corresponding to bit "1", or any one or several corresponding bits of K-order modulation symbols are "1";

[0345] OOK=0 means that all SCs are zero power (from the baseband perspective), corresponding to bit "0", or any one or several corresponding bits "0" of the K-order modulation symbols.

[0346] When the first signal is an OOK-1 signal, this 1-bit information can be used to trigger the signal of one OFDM symbol. To enable the base station to detect the terminal, this signal can be repeatedly transmitted N times. The base station receiver can continuously detect the user's signal or detect it during specific time periods. The specific detection method depends on the base station implementation or is based on relevant information related to the first signal sent by the terminal.

[0347] Method 2:

[0348] OOK-2: Parallel M-bits OOK in frequency domain.

[0349] The N SCs of the LP-WUS are further divided into M segments, each containing N / 2 subcarriers, as shown in Figure 6, where M = 2, with possible guard bands in between and / or around them. After performing an inverse fast Fourier transform (IFFT) and adding a cyclic prefix (CP) to the LP-WUS, the LP-WUS corresponds to M-bits of parallel OOK in the frequency domain. The SC of the LP-WUS is:

[0350] OOK=1 means that all SCs in the segment have been modulated, corresponding to bits "1", or any one or several corresponding bits "1" of the K-order modulation symbol;

[0351] OOK=0 means that all SCs in the segment are zero power (from the baseband point of view), corresponding to bit "0", or any one or several corresponding bits "0" of the K-order modulation symbol.

[0352] When the first signal is an OOK-2 signal, M bits in the frequency domain can carry the terminal discovery signal. For example, if the first signal is a specific sequence, for example, M bits of 1, the base station can detect the terminal based on a specific sequence pattern, such as "1010...1." The base station receiver can detect the user's signal continuously or during specific time periods. The specific detection method depends on the base station implementation or is based on information related to the first signal sent by the terminal.

[0353] Method 3:

[0354] OOK-3: Multi-tone single-bit OOK;

[0355] The Low Power Wake Up Signal (LP-WUS) consists of N subcarriers (SCs). The N SCs of the LP-WUS are divided into L segments, as shown in Figure 7, where L = 2. There is no guard band between segments, but there may be guard bands around the segments. After performing an Inverse Fast Fourier Transform (IFFT) and adding a cyclic prefix (CP) to the LP-WUS, a multi-tone single-bit OOK is obtained. In Figure 7, t0 and t1 represent the corresponding sequences of 0 and 1, respectively. The SC of the LP-WUS is:

[0356] OOK=1 means that one subcarrier of each segment (known to the UE) is modulated, and the rest of the SC is zero power (from the baseband point of view), corresponding to bit "1";

[0357] OOK=0 means that all SCs in all segments are zero power (from the baseband point of view), corresponding to bit "0".

[0358] If the first signal is an OOK-3 signal, it can carry the same frequency domain sequence information in different segments, or different frequency domain sequence information in different segments. On the base station side, with a certain time / frequency domain offset, the receiver can perform continuous detection in the time domain and / or frequency domain scanning to detect the first signal. Alternatively, the receiver can detect the user's signal within a specific time period or within a specific frequency domain resource range. The specific detection method depends on the base station implementation or is based on the relevant information of the first signal sent by the terminal.

[0359] Method 4: Time domain transformation M-bit OOK;

[0360] The N SCs of OOK-4 are generated by transformation (DFT / least squares);

[0361] As shown in Figure 8, N' samples are generated from M bits. The N SCs of the LP-WUS are generated through a transform (DFT / least squares). Signal modulation may or may not be used. Truncation or other additional modulation may or may not be used. If no additional modulation is used, N and N' are the same. After performing an inverse fast Fourier transform (IFFT) and adding a cyclic prefix (CP) to the LP-WUS, OOK-4 is obtained.

[0362] OOK-4 can be considered as an example of an OOK signal based on a single carrier (such as DFT-S-OFDM), and can also be used as a signal generation method independent of an uplink single carrier (such as DFT-S-OFDM).

[0363] The first signal / the second signal may also be an M-bit multi-carrier FSK signal, for example:

[0364] FSK-1: N SCs are divided into M pairs of segments, where M is an integer greater than or equal to 1, as shown in Figure 9 (M=2) and Figure 10 (M=4). There are potential guard bands between and around the segments. A segment consists of one subcarrier or multiple consecutive SCs. In a pair of segments, one is modulated and the other is zero power (from the baseband perspective).

[0365] FSK-2: N SCs are divided into 2 M Segments, where M is an integer greater than or equal to 0. As shown in Figure 11, M = 1, meaning N SCs are divided into two segments. As shown in Figure 12, M = 2, meaning N SCs are divided into four segments, with potential guard bands between and around them. A segment consists of one subcarrier or multiple consecutive SCs. One of the 2^M segments is modulated, while the other SC segments are at zero power (from a baseband perspective).

[0366] The first signal / second signal can also be based on CP-OFDM, which can multiplex the synchronization signal of NR in the related technology, and at the same time provide a higher data transmission rate. Furthermore, since the LP-WUR CP-OFDM signal and NR transmission are orthogonal, the protection bandwidth requirements between the two can be relaxed.

[0367] In the embodiments of the present disclosure, when the functions of the first signal and / or the second signal are different, their transceivers (transceivers) are different.

[0368] For example:

[0369] When the first signal is a discovery signal (i.e., the first signal is used to discover the terminal), the transceiver of the first signal is independent of the transceiver of the NR. The first signal includes at least an OFDM-based OOK / ASK / FSK / PSK signal.

[0370] When the first signal / second signal is a trigger signal (i.e., the first signal or second signal is used to wake up the cell, trigger the cell to send and / or receive signals or channels, and / or trigger the cell to switch states), the transceiver of the first signal or second signal is independent of the NR transceiver, or can be the same transceiver as the NR transceiver. The trigger signal includes at least an OFDM-based OOK / ASK / FSK / PSK signal.

[0371] The second signal is a trigger signal based on the NR signal, that is, the uplink / downlink supports CP-OFDM signals, and the uplink can support DFT-S-OFDM signals. The transceiver of this signal is the same as the NR transceiver.

[0372] In the embodiment of the present disclosure, when the receiver of the first signal and / or the second signal can be independent of the receiver of the uplink NR signal, the network side base station does not need to keep the corresponding NR receiver turned on, but only needs to detect the first signal and / or the second signal. The receiver of the signal only needs 1 / 10 of the power consumption of the NR receiver, which can achieve energy saving on the network side.

[0373] When the transmitter of the first signal and / or the second signal is the same transmitter as the transmitter of the uplink NR signal, the terminal can realize the function of base station discovery terminal only through the low-power transmitter.

[0374] When the transmitter of the first signal and / or the second signal is different from the transmitter of the uplink NR signal, the terminal only needs to send the first signal and / or the second signal through an independent transmitter, and this signal can be a relatively frequent and dense signal, thereby achieving the purpose of reducing the power consumption of the terminal.

[0375] When the first signal and / or the second signal is an OOK / ASK / FSK / PSK modulated signal based on OFDM, the architecture of the NR transceiver in the related technology can be utilized to further simplify the complexity of the transceiver, and the detection based on OOK / ASK / FSK / PSK modulation can greatly reduce the power consumption of the receiving end, thereby achieving energy saving.

[0376] As shown in FIG13 , an embodiment of the present disclosure further provides an information processing method, which is executed by a network-side device. The method includes:

[0377] Step 1301: Receive a first signal for at least one of the following:

[0378] Discovering a terminal; waking up a target cell; triggering the target cell to send or receive a first object; triggering the target cell to switch to a first state; wherein the first object includes at least one of a first target reference signal and a first target channel;

[0379] The first signal includes at least one of the following: an on-off keying (OOK) signal; an amplitude-shift keying (ASK) signal; a frequency-shift keying (FSK) signal; or a phase-shift keying (PSK) signal.

[0380] In some embodiments, the above-mentioned network side device includes a base station where the target cell is located, which can send and / or receive OFDM-based OOK / ASK / FSK / PSK signals and / or NR signals.

[0381] In some embodiments, the first signal may be received based on a dedicated receiver for the first signal, or may be received through an NR receiver.

[0382] In some embodiments, the target cell may continuously receive the first detection signal, periodically receive the first detection signal, or semi-continuously receive the first detection signal. The specific receiving algorithm may be determined by the internal algorithm of the target cell.

[0383] In some embodiments, the target cell includes at least one of a dormant cell, a closed cell, a sleeping cell, and a power-saving cell. The target cell may be a primary serving cell or a secondary cell, and the target cell has a cell identifier ID.

[0384] In some embodiments, the first signal includes signal information and indication information, where the signal information includes at least one of the amplitude, frequency, carrier, bandwidth, phase, power, and energy of the first signal. The indication information is used to indicate that the first signal is used for at least one of the following: discovering a terminal; waking up a target cell; triggering the target cell to send and / or receive a first object; or triggering the target cell to switch to the first state.

[0385] The OOK / ASK / FSK / PSK signal is a low-power signal. The network-side device can detect and process the OOK / ASK / FSK / PSK signal through envelope detection. This low-power signal enables the terminal to communicate with a dormant cell or a cell in an energy-saving state without synchronization, thereby waking up the dormant cell or triggering the dormant cell to wake up and provide service.

[0386] In the embodiment of the present disclosure, the above-mentioned OOK / ASK / FSK / PSK signal is a low-power signal different from the OFDM signal. The processing method of the low-power signal is different from the processing method of the OFDM signal in the related technology. The cell in the sleep state or the energy-saving state can process the low-power signal, so that the terminal can communicate with the sleep cell or the cell in the energy-saving state without synchronization through the low-power signal, thereby achieving the purpose of waking up the sleep cell or triggering the sleep cell to wake up and provide services.

[0387] In some embodiments, the first signal is a signal based on orthogonal frequency division multiplexing (OFDM), that is, the first signal is an OOK / ASK / FSK / PSK signal based on OFDM.

[0388] When the first signal is an OFDM-based OOK / ASK / FSK / PSK signal, the architecture of the NR transceiver in the related technology can be utilized to further avoid adding new transceivers, thereby simplifying the complexity of the transceiver. Signal detection based on OOK / ASK / FSK / PSK modulation can greatly reduce the power consumption of the receiving end because it does not require an inverse Fourier transform (IFFT) operation to perform envelope, filtering or phase detection, thereby achieving energy saving.

[0389] In some embodiments, the first signal carries at least one of the following:

[0390] Discover terminal related information, for example, information such as amplitude / phase / power / energy of a signal used for signal detection;

[0391] Related information about waking up the target cell, for example, includes target cell waking up indication information or information about the cell group where the target cell is located and information about the target cell or the cell group where the target cell is located, where the target cell waking up indication information is used to indicate whether to wake up the target cell;

[0392] Information related to the triggered target cell; for example, including indication information of the target cell or the cell group where the target cell is located and information related to the identifier of the target cell or the cell group where the target cell is located. The trigger target cell indication signal is used to indicate the target cell to be triggered;

[0393] Relevant information for triggering the target cell to send and / or receive the first object, for example, including first target reference signal sending and / or receiving indication information, where the indication information is used to indicate at least one of the first target reference signal and the first target channel to be sent or received by the target cell;

[0394] The relevant information for triggering the target cell to switch to the first state includes, for example, cell state indication information.

[0395] As an implementation manner, the first signal carries at least one of the following:

[0396] Wake-up cell indication information, used to indicate whether to wake up the target cell;

[0397] Cell identity related information, used to indicate relevant cell information for sending / receiving a wake-up or triggering signal / channel;

[0398] First object sending / receiving indication information, used to indicate the first object sent / received by the target cell;

[0399] Function trigger indication information is used to instruct the target cell to enable or disable specific functions, such as measurement, synchronization, positioning, access, energy saving, and specific service transmission;

[0400] Terminal specific identifier, used to indicate the specific type or terminal identifier of the terminal, such as terminal type identifier, terminal version identifier, terminal identifier supporting specific services, and related indications of whether the target cell can be woken up;

[0401] Terminal demand information related identifiers are used to indicate the terminal's current service requirements, such as access, measurement, synchronization, positioning, energy saving, and specific service transmission requirements; or indicate the terminal's current service requirements, such as eMBB services, XR services, URLLC services, mMTC services, AIoT services, etc. Cell state indication information is used to indicate that the target cell is switching between at least two states, or switching to the first state.

[0402] In an embodiment of the present disclosure, the network side device may wake up the target cell after receiving the above-mentioned first signal for a certain period of time; trigger the target cell to send and / or receive the first object; and trigger the target cell to switch to the first state.

[0403] When the terminal does not receive any synchronization signal sent by the target cell, such as the primary synchronization signal (PSS), the secondary synchronization signal (SSS), the synchronization signal / physical broadcast channel signal block (SSB), etc., or when the synchronization signal sent by the target cell is received at a longer time interval, such as PSS, SSS, SSB, etc., the terminal cannot achieve synchronization or fine synchronization with the base station, and the terminal cannot send any signal to the base station based on the NR signal in the related technology. In the embodiment of the present disclosure, the terminal sends a first signal, which is a modulated signal based on OOK / ASK / FSK / PSK. There is no need for precise synchronization between the base station and the terminal. The first signal can be detected based on the amplitude / power / energy / phase and other related information of the first signal, that is, the effect of detecting the terminal without precise synchronization is achieved.

[0404] In some embodiments, the first signal may also jointly indicate at least one of waking up the target cell, triggering the target cell to send and / or receive the first object, and triggering the target cell to switch to the first state. That is, when the base station detects the first signal of the terminal, it may wake up the target cell, trigger the target cell to send and / or receive the first object, and trigger the target cell to switch to the first state. The specific joint indication may be defined by the protocol and determined by at least one of the following: terminal pre-stored information, core network information, and terminal historical information.

[0405] In some embodiments, when the terminal can achieve coarse synchronization with the base station, the first signal can further carry at least one indication information such as waking up the target cell; triggering the target cell to send and / or receive the first object; triggering the target cell to switch to the first state. For example, when the first signal is a different time domain or frequency domain sequence pattern, it corresponds to different indication information. When the base station detects that the first signal is a specific time domain or frequency domain sequence pattern, it obtains the corresponding indication information, and then sends and / or receives at least one of a specific reference signal and a specific channel. In this way, the base station does not need to continuously send a synchronization signal for fine synchronization to the terminal, such as an SSB with a period of less than or equal to 160ms, that is, when the base station achieves energy saving on the network side, it can also be awakened according to the terminal service needs, or triggered to send and / or receive the first object, or switch to the transmission and reception of signals / channels in different energy-saving states, so as not to affect the business service needs of the terminal.

[0406] When the first signal implicitly or explicitly triggers the target cell to send and / or receive the first object, at least one of the specific reference signal and the specific channel can be triggered in a targeted manner. For example: according to service requirements, the terminal needs to trigger the target cell to send SSB and / or tracking reference signal (Tracking Reference Signal, TRS) for synchronization service, and the positioning service needs to trigger the target cell to send positioning reference signal (Positioning Reference Signal, PRS) and / or receive sounding reference signal (SRS) for positioning service. The measurement needs to trigger the target cell to send SSB, send a preamble (preamble) and / or CSI reference signal (CSI Reference Signal, CSI-RS) for random access, and the access needs to send SSB and receive at least one of the physical random access channel (Physical Random-Access Channel, PRACH). The base station only needs to send and / or receive the above-mentioned reference signals and / or channels according to the first signal, and does not need to send and / or receive all reference signals and channels, thereby achieving energy saving on the network side.

[0407] When the first signal implicitly or explicitly triggers the target cell to switch to the first state, here, the first state can be one of at least one cell state, or different cell states corresponding to different parameter configuration sets. Here, the cell state can be a cell energy-saving state, or a cell providing different service states. For example: the terminal can select a cell based on its business needs, such as: the terminal only needs to perform RRM measurement to select a cell. At this time, the target cell only needs to be in a light sleep state and send SSB or CSI-RS with a period of 80ms. The base station only needs to trigger the reference signal / channel sending / receiving in the light sleep state according to the first signal, so as to achieve energy saving of the base station while meeting the business needs of the terminal.

[0408] In some embodiments, after receiving the first signal, the method further includes:

[0409] A first response signal is sent to the first signal.

[0410] In some embodiments, sending a first response signal to the first signal includes:

[0411] When the signal information of the first signal satisfies a first condition, sending a first response signal to the first signal;

[0412] The signal information includes at least one of the amplitude, frequency, carrier, bandwidth, phase, power and energy of the first signal.

[0413] For example, the base station performs first signal detection and obtains M bits of information carried by the first signal, where M is greater than or equal to 0, and the first signal includes signal information and / or carries indication information. When the base station detects that the signal information of the first signal meets a specific threshold or a specific value, the base station sends a first response signal.

[0414] In some embodiments, the method of the present disclosure further includes:

[0415] If the signal information of the first signal satisfies a first condition, performing at least one of the following:

[0416] Discovering a terminal; waking up a target cell; triggering the target cell to send or receive a first object; triggering the target cell to switch to a first state;

[0417] The signal information includes at least one of the amplitude, frequency, carrier, bandwidth, phase, power and energy of the first signal.

[0418] In some embodiments, the first response signal carries at least one of the following:

[0419] Confirmation information of the first signal; the confirmation information may be an OOK / ASK / FSK / PSK signal, for example, an OFDM-based OOK / ASK / FSK / PSK signal;

[0420] Feedback information on the first signal; the feedback information may be an OOK / ASK / FSK / PSK signal, for example, an OFDM-based OOK / ASK / FSK / PSK signal;

[0421] A first reference signal and / or a first channel; the first reference signal is used as a reference signal for whether a subsequent terminal wakes up a dormant cell or provides a reference signal for a specific function for the terminal. For example, the specific function may be synchronization, measurement or positioning functions. The reference signal may be PSS, SSS, SSB, CSI-RS, TRS, PRS, PTRS, PRACH, etc. The first channel includes a downlink control channel and / or an uplink control channel.

[0422] Cell information of the cell that sends the first response signal, such as cell identification information.

[0423] In some embodiments, the first response signal may be sent by at least one base station that receives the first signal.

[0424] For feedback information or confirmation information of the first response signal being the first signal, in order to prevent the base station from being awakened by each terminal of the first signal, or being triggered to send / receive signals, or being triggered to switch to the first state of the cell, thereby affecting the energy saving gain of the base station. After detecting the first signal, the base station can determine whether to be awakened, or triggered to send / receive signals, or triggered to switch to the first state of the cell for confirmation or feedback based on the internal implementation algorithm, and further instruct the terminal whether to wake up the cell, or whether to trigger sending / receiving signals, or whether to trigger switching to the first state of the cell, or whether to receive the first signal. On the one hand, it reduces the base station from being awakened unconditionally, and on the other hand, it reduces the terminal from continuously sending the first signal, so that both parties understand each other.

[0425] If the first response signal is a first reference signal and / or a first channel, for example, after detecting the first signal, the base station transmits the first reference signal, such as the PSS, SSS, TRS, or SSB, and receives the PRACH channel and the PDCCH on which paging is located. These signals can be used by the terminal for subsequent communication activities, such as synchronization, RRM measurement, cell access, random access, and paging. The terminal receives and / or transmits the first reference signal and / or the first channel at specific intervals after transmitting the first signal. After receiving the response signal from at least one cell, the terminal selects a target cell to provide service to the terminal through a specific algorithm, such as a cell selection process. If no terminal accesses the other cells that sent the response signal within a specific time period, the terminal may enter a dormant state. If the terminal receives the response signal from only one cell, the current cell is selected as the target cell, and the terminal accesses the target cell. This method eliminates the need for cells to remain in service, thereby reducing network-side energy consumption. Alternatively, the terminal can access the target cell by detecting the first reference signal and / or first channel transmitted / received by the target cell to obtain the target cell's services, thereby reducing the impact on service performance.

[0426] In addition, the terminal can further transmit signals to the target cell when it is synchronized with the network side by receiving the first response signal, and provide a precondition for receiving and transmitting at least one of the target reference signal, target channel, target indication information, and the second signal triggered by the target cell, that is, the transmitting and receiving parties are synchronized. In some embodiments, the method of the embodiment of the present disclosure further includes:

[0427] Obtain a second signal, where the second signal is used for at least one of the following: waking up a specific cell; triggering the specific cell to send or receive a second object; triggering the specific cell to switch to a second state, wherein the second object includes at least one of a second target reference signal and a second target channel.

[0428] In an embodiment of the present disclosure, the terminal may determine, based on the first response signal, to which target cell to send the second signal. That is, the specific cell is one or more cells among the target cells. Specifically, the terminal may randomly determine one or more cells (i.e., the specific cells) among the target cells that sent the first response signal, or may determine one or more cells (i.e., the specific cells) among the target cells that sent the first response signal in other ways.

[0429] In some embodiments, the second signal carries at least one of the following:

[0430] Wake up the relevant information of a specific cell;

[0431] Triggering specific cell related information;

[0432] triggering a specific cell to send and / or receive relevant information of a second object;

[0433] Relevant information for triggering a specific cell to switch to the second state.

[0434] As an implementation manner, the second signal carries at least one of the following:

[0435] Cell wake-up indication information, used to indicate whether to wake up a specific cell;

[0436] Cell identity related information, used to indicate relevant cell information for sending / receiving a wake-up or triggering signal / channel;

[0437] Second object sending / receiving indication information, used to indicate the second object sent / received by a specific cell;

[0438] Function trigger indication information is used to instruct a specific cell to enable or disable specific functions, such as measurement, synchronization, positioning, energy saving, access, and specific service transmission;

[0439] Terminal specific identifier, used to indicate the specific type or terminal identifier of the terminal; such as terminal type identifier, terminal version identifier, terminal identifier supporting specific services, and related indications of whether the target cell can be woken up;

[0440] Terminal demand information related identifiers are used to indicate the current service requirements of the terminal, such as access, measurement, synchronization, positioning, energy saving, access, and specific service transmission requirements; or, to indicate the current service requirements of the terminal, such as eMBB service, XR service, URLLC service, mMTC service, AIoT service, etc.

[0441] The cell state indication information is used to instruct a specific cell to switch between at least two states, or to switch to a second state.

[0442] When the terminal sends the first signal, it may also send a second signal to further provide the base station with additional information. The additional information includes at least one of the following: enhanced or supplementary information of the first signal, i.e., information that improves the reception performance of the first signal, or provides supplementary information of the first signal.

[0443] For information about the second signal used to improve reception performance of the first signal, such as when the second signal is a duplicate of the first signal or carries information related to the first signal, but the first and second signals are different signals, the terminal sending the second signal can improve the base station's ability to discover the terminal and obtain information carried by the first and / or second signals.

[0444] The second signal is used to provide supplementary information about the first signal. For example, the first signal is transmitted based on a broadcast when the terminal and the base station are not synchronized or precisely synchronized, and serves as a signal for the base station to discover the terminal. The second signal can be sent as supplementary information for the terminal, such as the terminal version or terminal type, to enable the discovery of a target cell that can serve the terminal. After the base station detects the first signal, it detects the second signal. If the cell can provide service to the terminal, the cell is awakened as the target cell and triggered to send or receive the second object, triggering the switching to at least one of the second states. In this way, by sending the second signal, the accuracy of waking up or triggering the target cell can be improved, thereby improving network energy saving performance.

[0445] After receiving the first response signal, the terminal transmits a second signal to further instruct the target cell to wake up, trigger the target cell to send or receive a second object, and trigger the target cell to switch to at least one of the second states. Upon receiving the first response signal, such as for synchronization signals PSS, SSS, TRS, SSB, etc., the terminal can synchronize with the base station. The terminal can transmit the second signal, which carries indication information for the target cell, to wake up the target cell, trigger the target cell to send or receive a second object, and trigger the target cell to switch to at least one of the second states. The target cell can provide a specific indication via the second signal, or an implicit indication via a second signal that has a specific correlation with the response signal sent by the target cell. The target cell can transmit a synchronization signal based on the terminal's service needs to obtain more precise indication information, such as indication information related to being woken up by the terminal, indication information related to triggering the sending or receiving of the second object, or indication information related to triggering switching to a specific cell state, without having to constantly provide synchronization signals with the terminal, thereby achieving network-side energy conservation.

[0446] In some embodiments, the second signal may also jointly indicate at least one of waking up a specific cell, triggering the specific cell to send and / or receive a second object, and triggering the specific cell to switch to a second state. That is, when the base station detects the second signal from the terminal, it may wake up the specific cell, trigger the specific cell to send and / or receive a second object, and trigger the specific cell to switch to the second state. The specific joint indication may be defined by the protocol and determined by at least one of terminal pre-stored information, core network information, and terminal historical information.

[0447] In some embodiments, when the terminal can achieve coarse synchronization with the base station, the second signal can further carry indication information of at least one of waking up a specific cell; triggering a specific cell to send and / or receive a second object; and triggering a specific cell to switch to a second state. For example, when the second signal is a different time domain or frequency domain sequence pattern, it corresponds to different indication information. When the base station detects that the second signal is a specific time domain or frequency domain sequence pattern, it obtains the corresponding indication information, and then sends and / or receives at least one of a specific reference signal and a specific channel. In this way, the base station does not need to continuously send a synchronization signal for fine synchronization to the terminal, such as an SSB with a period of less than or equal to 160ms, that is, when the base station achieves energy saving on the network side, it can also be awakened according to the terminal service needs, or triggered to send and / or receive the second object, or switch to the transmission and reception of signals / channels in different energy-saving states, so as not to affect the business service needs of the terminal.

[0448] When the second signal implicitly or explicitly triggers a specific cell to send and / or receive a second object, at least one of a specific reference signal and a specific channel can be triggered in a targeted manner. For example: according to service requirements, the terminal needs to trigger the target cell to send SSB and / or tracking reference signal (TRS) for synchronization service, and the target cell needs to send positioning reference signal (PRS) and / or receive sounding reference signal (SRS) for positioning service. The measurement needs to trigger the target cell to send SSB and / or CSI reference signal (CSI Reference Signal, CSI-RS). Access requires sending SSB, sending random access preamble (preamble) and receiving physical random access channel (PRACH) and at least one of the above. The base station only needs to send and / or receive the above reference signals and / or channels according to the second signal, and does not need to send and / or receive all reference signals and channels, thereby achieving energy saving on the network side.

[0449] When the second signal implicitly or explicitly triggers the target cell to switch to the second state, here, the second state can be one of at least one cell state, or different cell states corresponding to different parameter configuration sets. Here, the cell state can be a cell energy-saving state, or a cell providing different service states. For example: the terminal can select a cell based on its business needs, such as: the terminal only needs to perform RRM measurements to select a cell. At this time, the target cell only needs to be in a light sleep state and send SSB or CSI-RS with a period of 80ms. The base station only needs to trigger the reference signal / channel sending / receiving in a light sleep state according to the second signal, thereby achieving energy saving of the base station while meeting the business needs of the terminal. In some embodiments, the method of the embodiment of the present disclosure also includes:

[0450] A second response signal is sent, where the second response signal is a response signal to a target signal, and the target signal includes the second signal, or includes the first signal and the second signal.

[0451] In the embodiment of the present disclosure, the base station may send a first response signal after receiving the first signal and send a second response signal after receiving the second signal, or may send the above-mentioned second response signal after receiving the first signal and the second signal.

[0452] In some embodiments, the second response signal carries at least one of the following:

[0453] Confirmation information of the target signal; the confirmation information may be an OOK / ASK / FSK / PSK signal, for example, an OFDM-based OOK / ASK / FSK / PSK signal;

[0454] Feedback information of the target signal; the feedback information may be an OOK / ASK / FSK / PSK signal, for example, an OFDM-based OOK / ASK / FSK / PSK signal;

[0455] A second reference signal or a second channel; the second reference signal is used as a reference signal for whether a subsequent terminal wakes up a dormant cell or provides a reference signal for a specific function for the terminal. For example, the specific function may be synchronization, measurement or positioning functions. The reference signal may be SSB, CSI-RS, TRS, random access preamble, etc. The second channel includes a downlink control channel and / or an uplink control channel.

[0456] Cell information of the cell that sends the second response signal, such as cell identification information.

[0457] In some embodiments, the second response signal may be sent by the target cell that receives the second signal.

[0458] For feedback information or confirmation information of the second response signal being the second signal, in order to avoid the base station being awakened by each terminal of the second signal, or being triggered to send and / or receive signals, or being triggered to switch to the second state of the cell, affecting the energy saving gain of the base station. After the base station detects the second signal, it can determine whether to be awakened according to the internal implementation algorithm, or be clearly indicated by the second signal whether to be awakened, or be triggered to send / receive signals, or be triggered to switch to the second state of the cell for confirmation or feedback, and further instruct the terminal whether to wake up the cell, or whether to trigger sending / receiving signals, or whether to trigger switching to the second state of the cell, or whether to receive the second signal. On the one hand, it reduces the base station from being awakened unconditionally, and on the other hand, it responds to the second signal sent by the terminal, so that both parties understand each other.

[0459] The second response signal is a second reference signal and / or a second channel. For example, after the base station detects the second signal, it sends a second reference signal, such as PSS, SSS, TRS, SSB, etc., and receives the channel PRACH, PDCCH where Paging is located, etc., which can be used by the terminal to perform at least one of subsequent synchronization, RRM measurement, cell access, random access and paging. The terminal receives / sends the second reference signal and / or the second channel in a specific time period after receiving the second response signal. After receiving the response signal, the target cell provides service to the terminal. The cell that does not send the second response signal cannot be accessed by the terminal within a specific time period, and the cell enters a dormant state and does not need to be in a service state all the time, thereby reducing energy consumption on the network side.

[0497] It should be noted that the fourth moment, the fifth moment and the sixth moment in the embodiment of the present disclosure may be the same or different.

[0498] The following describes the process of waking up or triggering a base station service using an OOK / ASK / FSK / PSK signal in conjunction with Embodiments 2 to 5.

[0499] Embodiment 2: The base station is awakened after receiving the first signal.

[0500] As shown in Figure 14, the process includes:

[0501] Step 1: The terminal sends a first signal for the surrounding dormant cells / base stations (such as Pico base stations) to discover the terminal, wherein the first signal is an OFDM-based OOK / ASK / FSK / PSK signal. The first signal can be sent through a first signal dedicated transmitter or through an NR transmitter. The first signal can be sent N times at a specific time point or time period, where N is greater than or equal to 1. The specific sending location can be determined by one or more methods such as neighboring cell high-level signaling configuration, core network signaling configuration, broadcast signaling, or protocol limitation.

[0502] Step 2: The base station performs a first signal detection and obtains information carried by the first signal, including signal information and / or carried indication information. If the first signal meets a specific condition (i.e., the first condition), the cell is directly awakened, or if the first signal does not meet the specific condition, the cell is not awakened. Here, the first signal can carry M bits of information, where M is greater than or equal to 1, and the information carried includes at least one of the following:

[0503] Signal amplitude / phase / power / energy and other related information;

[0504] Instruction information used to wake up the cell.

[0505] In this embodiment, the first signal can be received by a dedicated receiver based on the first signal, or by an NR receiver.

[0506] For example:

[0507] Assuming that the first signal is an OOK signal based on OFDM, when the base station detects the first signal, it obtains one of the related information such as amplitude / phase / power / energy, such as: obtaining the power value of its signal as P, or obtaining the amplitude value of its signal as A, or obtaining the energy value of its signal as E, or obtaining the phase information of its signal as θ.

[0508] Assume that the first signal is an OFDM-based OOK signal, which carries N bits of indication information through modulation and the like, where N is greater than or equal to 1, and is used to indicate waking up the target cell.

[0509] Specifically, the specific condition may be: the amplitude / phase / power / energy of the signal, etc., meets a specific threshold or a specific value or a specific value range.

[0510] For example, assuming that the specific condition is greater than the power value threshold P0, if the base station detects that the power value P of the first signal is greater than the power value threshold P0, it determines that the current terminal falls within the service range of the base station; otherwise, the base station determines that the current terminal does not fall within the service range of the base station.

[0511] Assuming that the specific condition is greater than the amplitude threshold value A0, if the base station detects that the amplitude value A of the first signal is greater than the amplitude threshold value A0, it determines that the current terminal is within the service range of the base station; otherwise, the base station determines that the current terminal is not within the service range of the base station.

[0512] Assuming that the specific condition is greater than the energy threshold value E0, if the base station detects that the energy value E of the first signal is greater than the energy threshold value E0, it determines that the current terminal is within the service range of the base station; otherwise, the base station determines that the current terminal is not within the service range of the base station.

[0513] Assuming a specific condition of being within the phase value range {Θmax, Θmin}, if the base station detects that the phase value θ of the first signal is within this phase value range, the base station determines that the current terminal is within the base station's service range. Otherwise, the base station determines that the current terminal is not within the base station's service range. For example, when the terminal transmits the first signal, it can perform different phase modulations on base stations in different directions, with {0, π} representing a cell in one direction and {π, 2π} representing a cell in another direction. The base station performs coherent demodulation on the received signal to obtain the phase value range of the first signal.

[0514] Assuming that the specific condition is that the indication information carried by the first signal is a specific value, such as: all N bits are 1. If the base station detects that the indication information carried by the first signal meets the specific value, it is determined that the current terminal falls within the service range of the base station; otherwise, the base station determines that the current terminal does not fall within the service range of the base station.

[0515] When the base station determines that the current terminal is within the service range of the base station, the dormant cell is awakened and sends SSB signals, or CSI-RS or reference signals for positioning to provide regular services to the terminal; otherwise, the dormant cell will not be awakened.

[0516] Step 3: If the cell is awakened, perform at least one of the following:

[0517] Restore service status;

[0518] Enter a light sleep state;

[0519] Send SSB / SIB1.

[0520] The terminal synchronizes, searches for cells, performs random access, or sends a scheduling request for the SSB sent by the wake-up cell.

[0521] Embodiment 3: After receiving the first signal, the base station is triggered to send / receive the first object;

[0522] As shown in Figure 15, the process includes:

[0523] Step 1: The terminal sends a first signal for the surrounding dormant cells / base stations (such as Pico) to discover the terminal, wherein the first signal is an OFDM-based OOK / ASK / FSK / PSK signal. The first signal can be sent through a first signal dedicated transmitter or through an NR transmitter. The first signal can be sent N times at a specific time point or time period, where N is greater than or equal to 1. The specific sending location can be determined by one or more methods such as neighboring cell high-level signaling configuration, core network signaling configuration, broadcast signaling, or protocol limitation.

[0524] Step 2: The base station performs a first signal detection and obtains information carried by the first signal, including signal information and / or carried indication information. If the first signal meets a specific condition (i.e., the first condition), the cell is triggered to send a specific reference signal, or if the first signal does not meet the specific condition, the cell does not send the specific reference signal. Here, the first signal can carry M bits of information, where M is greater than or equal to 1, and the information carried includes at least one of the following:

[0525] The signal information carried by the first signal may be related information such as the amplitude / phase / power / energy of the signal.

[0526] The indication information carried by the first signal is used to trigger the cell to receive and / or send signals.

[0527] In this embodiment, the first signal can be received by a dedicated receiver based on the first signal, or by an NR receiver.

[0528] For example:

[0529] Assuming that the first signal is an OOK signal based on OFDM, when the base station detects the first signal, it obtains one of the related information such as amplitude / phase / power / energy, such as: obtaining the power value of its signal as P, or obtaining the amplitude value of its signal as A, or obtaining the energy value of its signal as E, or obtaining the phase information of its signal as θ.

[0530] Specifically, the specific condition may be: the amplitude / phase / power / energy of the signal, etc., meets a specific threshold or a specific value or a specific value range.

[0531] For example:

[0532] Assuming that the specific condition is greater than the power value threshold P0, if the base station detects that the power value P of the first signal is greater than the power value threshold P0, it determines that the current terminal needs the base station side to send / receive a specific reference signal; otherwise, the base station determines that the current terminal does not need to send / receive a specific reference signal.

[0533] Assuming that the specific condition is greater than the amplitude threshold value A0, if the base station detects that the amplitude value A of the first signal is greater than the amplitude threshold value A0, it is determined that the current terminal needs the base station side to send / receive a specific reference signal; otherwise, the base station determines that the current terminal does not need to send / receive a specific reference signal.

[0534] Assuming that the specific condition is greater than the energy threshold value E0, if the base station detects that the energy value E of the first signal is greater than the energy value threshold value E0, it determines that the current terminal needs the base station side to send / receive a specific reference signal; otherwise, the base station determines that the current terminal does not need to send / receive a specific reference signal.

[0535] Assuming that the specific condition is within the phase value range {Θmax, Θmin}, if the base station detects that the phase value θ of the first signal is within the phase value range, it is determined that the current terminal needs the base station side to send / receive a specific reference signal; otherwise, the base station determines that the current terminal does not need to send / receive a specific reference signal.

[0536] For example, when the base station determines that the current terminal needs the base station side to send / receive a specific reference signal, the dormant cell sends a specific reference signal according to the protocol definition or according to the indication information carried by the first signal, such as: SSB signal, TRS signal, CSI-RS signal, reference signal PRS / SRS for positioning, etc.; conversely, the dormant cell or the cell in the energy-saving state will not send / receive a specific reference signal. The configuration of the reference signal is the default parameter configuration defined by the protocol. The specific reference signal can be one or more signals defined by the protocol, such as: when the protocol defines that the base station receives the first signal and meets specific conditions, it sends an SSB signal. The SSB signal is sent according to the default 20ms period. The same applies to other reference signals.

[0537] Assume that the specific condition is that the indication information carried by the first signal is the indication information of a specific reference signal, that is, different values ​​correspond to different reference signals, such as: N bits correspond to M types of reference signals, and the base station triggers the sending and / or reception of the corresponding specific reference signal according to the indication information.

[0538] For example, when a base station receives a first signal, and the first signal carries indication information of a specific reference signal, such as bit N1 in N bits is used to indicate a positioning reference signal PRS, the base station sends the PRS signal according to the default parameter configuration or the parameter configuration defined by the protocol. In some embodiments, when the base station determines that the current terminal requires the base station side to send / receive a specific reference signal, the dormant cell can configure a parameter among multiple configurations of the specific reference signal according to the indication information. For example, if the base station receives indication information carried by the first signal indicating the sending of a positioning reference signal PRS, and indicates a parameter configuration among the pre-configured parameter configurations, the base station sends the specific reference signal according to the specific parameter configuration.

[0539] Step 3: When the cell is triggered to send a specific reference signal, perform at least one of the following:

[0540] Send SSB / SIB1

[0541] Send downlink synchronization signal TRS

[0542] Send positioning reference signal.

[0543] The terminal performs synchronization, cell search, random access, or sends a scheduling request based on a specific reference signal sent by the dormant cell.

[0544] Embodiment 4: The base station is fully or partially awakened after sending the first response signal;

[0545] As shown in Figure 16, it includes:

[0546] Step 1: The terminal sends a first signal for nearby dormant cells / base stations (e.g., Pico) to discover the terminal. The first signal is an OFDM-based OOK / ASK / FSK / PSK signal. The first signal can be sent via a dedicated first signal transmitter or an NR transmitter.

[0547] Step 2: The base station performs a first signal detection and obtains information carried by the first signal, including signal information and / or carried indication information. If the first signal meets a specific condition (i.e., the first condition), a first response signal is sent to the terminal. Alternatively, if the first signal does not meet the specific condition, the cell does not send the first response signal. Here, the first signal can carry M bits of information, where M is greater than or equal to 1, and the information carried includes at least one of the following:

[0548] Signal amplitude / phase / power / energy and other related information.

[0549] Indication information used to trigger the cell to receive and / or send signals.

[0550] In this embodiment, the first signal can be received by a dedicated receiver based on the first signal, or by an NR receiver.

[0551] For example:

[0552] Assuming that the first signal is an OOK signal based on OFDM, when the base station detects the first signal, it obtains one of the related information such as amplitude / phase / power / energy, such as: obtaining the power value of its signal as P, or obtaining the amplitude value of its signal as A, or obtaining the energy value of its signal as E, or obtaining the phase information of its signal as θ.

[0553] Taking the OOK-1 signal as an example, the first signal can carry 1 bit of information for terminal discovery in dormant cells. The first signal can be sent N times at a specific time point or time period, where N is greater than or equal to 1. The specific sending location can be determined by one or more methods, such as neighboring cell high-layer signaling, core network signaling, broadcast signaling, or protocol definition.

[0554] Step 3: The base station sends a first response signal to the first signal. Here, the first response signal may be sent by the base station when it detects that signal information of the first signal meets a specific condition. Specifically, the specific condition may be: the amplitude / phase / power / energy of the signal meets a specific threshold, a specific value, or a specific value range. The first response signal may also be sent by the base station upon detecting the first signal.

[0555] For specific conditions, please refer to Example 2 and Example 3.

[0556] The first response signal may carry at least one of the following:

[0557] The first item carries the confirmation information of the cell for receiving the first signal, for example, N-bit ACK information. Here, the first response signal can be an OFDM-based OOK / ASK / FSK / PSK signal.

[0558] For example, if a base station detects that the signal amplitude exceeds a specific threshold within a certain period of time, it determines that a terminal has entered the service range of the cell. Therefore, the base station determines that the terminal needs to be awakened and sends a first response signal to the terminal. For example, this signal carries a 1-bit OOK signal. After sending the first signal, the terminal performs reception detection of the first response signal within a specific time interval.

[0559] The second item carries cell information of the current cell. For example, the cell information may be a predefined sequence or signal pattern. Here, the first response signal may be an OFDM-based OOK / ASK / FSK / PSK signal. The predefined sequence or signal pattern corresponding to the cell information may be preconfigured by the terminal or defined by a neighboring cell, the core network, or a protocol.

[0560] For example, if a base station detects that a signal amplitude exceeds a specific threshold within a certain period of time, it determines that a terminal has entered the service range of the cell. Therefore, the base station determines that the terminal needs to be awakened and sends a first response signal to the terminal. This first response signal includes M bits of information corresponding to preconfigured or predefined cell information. After sending the first signal, the terminal performs reception detection of the first response signal within a specific time interval.

[0561] Item 3: Feedback information of the cell regarding the indication information carried by the first signal, for example, feedback information carried by the first signal.

[0562] For example: the N-bit information of the first signal carries indication information of M1 specific reference signals and / or M2 specific parameter configurations. When the base station side detects the first signal and meets specific conditions, it sends feedback information corresponding to the indication information to the terminal, that is, confirmation information of the m1-th specific reference signal indication information and / or confirmation information of the m2-th parameter configuration indication information.

[0563] Item 4: Reference signal used for terminal time and frequency synchronization, such as SSB signal.

[0564] For example, if a base station detects that the signal amplitude exceeds a specific threshold within a certain period of time, it determines that a terminal has entered the service range of the cell. Therefore, the base station determines that it needs to be awakened and sends a response signal to the terminal. The first response signal is a specific reference signal, such as the SSB signal used for terminal time and frequency synchronization.

[0565] Step 4: After the specific cell sends the first response signal, perform at least one of the following:

[0566] Restore service status, that is, fully awakened;

[0567] Enter a light sleep state;

[0568] Send SSB / SIB1;

[0569] Send downlink synchronization signal TRS;

[0570] Send positioning reference signal.

[0571] Step 5: After receiving the first response signal, the terminal receives the SSB or specific reference signal, performs synchronization, cell search, random access, or sends a scheduling request.

[0572] Embodiment 5: The base station sends a second signal to wake up or trigger the sending / receiving of the second object;

[0573] As shown in Figure 17, the process includes:

[0574] Step 1: The terminal sends a first signal for nearby dormant cells / base stations (e.g., Pico) to discover the terminal. The first signal is an OFDM-based OOK / ASK / FSK / PSK signal. The first signal can be sent via a dedicated first signal transmitter or an NR transmitter.

[0575] Step 2: The base station detects the first signal and obtains information carried by the first signal, including signal information and / or carried indication information. Here, the information carried by the first signal includes at least one of the following:

[0576] The signal information carried by the first signal may be related information such as the amplitude / phase / power / energy of the signal.

[0577] The indication information carried by the first signal is used to trigger the cell to receive and / or send signals.

[0578] In this embodiment, the first signal can be received by a dedicated receiver based on the first signal, or by an NR receiver.

[0579] For example:

[0580] Assuming that the first signal is an OOK signal based on OFDM, when the base station detects the first signal, it obtains one of the related information such as amplitude / phase / power / energy, such as: obtaining the power value of its signal as P, or obtaining the amplitude value of its signal as A, or obtaining the energy value of its signal as E, or obtaining the phase information of its signal as θ.

[0581] Step 3: The base station sends a first response signal to the first signal. Here, the first response signal may be sent by the base station when it detects that signal information of the first signal meets a specific condition. Specifically, the specific condition may be: the amplitude / phase / power / energy of the signal meets a specific threshold, a specific value, or a specific value range. The first response signal may also be sent by the base station upon detecting the first signal.

[0582] For specific conditions, please refer to Example 2 and Example 3.

[0583] The first response signal may be at least one of the following:

[0584] The first item carries the confirmation information of the cell for receiving the first signal, for example, N bits of ACK information, which is used to indicate that the base station has detected the first signal.

[0585] The second item carries the cell information of the current cell, etc. For example, the cell information may be a predefined sequence or signal pattern.

[0586] Item 3: Feedback information of the cell regarding the indication information carried by the first signal, for example, feedback information carried by the first signal.

[0587] Item 4: a specific reference signal (ie, a first reference signal) sent / received by a cell.

[0588] For example:

[0589] If the first signal is used to wake up the dormant cell, the base station sends a first response signal to confirm that the cell has been woken up.

[0590] If the first signal carries relevant information of the cell, the base station sends a first response signal to feedback whether it is the target cell for the terminal to wake up.

[0591] If the first signal carries indication information of the triggered sending / receiving of the first target reference signal, the base station performs feedback according to the indication information.

[0592] If the base station receives the first signal, it sends a first response signal to the terminal, including confirmation information and / or a specific reference signal, such as at least one of an SSB signal and a SIB signal.

[0593] Step 4: After receiving the first response signal, the terminal receives the specific reference signal (first reference signal), such as SSB, and performs synchronization and cell search. If the current cell meets the cell search or cell reselection conditions, the terminal sends a second signal to the accessed specific cell to wake up or trigger the sending / receiving of the specific reference signal (i.e., the second target reference signal). Here, the second signal can be an OFDM-based OOK / ASK / FSK / PSK signal or an NR signal.

[0594] For example:

[0595] If the second signal is an OFDM-based OOK / ASK / FSK / PSK signal, the generation method and the carried information may refer to the first signal in the previous embodiment.

[0596] If the second signal is an NR signal, it can be an uplink control signaling based on PUCCH or an uplink reference signal based on a sequence. Among them, the uplink control signaling based on PUCCH is a dedicated signaling for cell wake-up.

[0597] The second signal may carry at least one of the following information:

[0598] Cell wake-up indication information, i.e. whether to wake up a dormant cell;

[0599] Cell identity related information, i.e., related cell information used to indicate the sending and / or receiving of wake-up or trigger signals / channels;

[0600] Specific reference signal (i.e., second target reference signal) sending and / or receiving indication information, i.e., used to indicate the specific reference signal sent / received by the cell;

[0601] Function trigger indication information, i.e., used to instruct the cell to turn on or off specific functions, such as measurement, synchronization, positioning, energy saving, access, and specific service transmission;

[0602] Terminal specific identification, i.e., used to indicate the specific type or terminal identification of the terminal, such as terminal type identification, terminal version identification, terminal identification supporting specific services, and related indications of whether the target cell can be woken up;

[0603] Terminal demand information related identifiers, i.e., used to indicate the current service requirements of the terminal, such as access, measurement, synchronization, positioning, energy saving, and specific service transmission requirements; or, to indicate the current service requirements of the terminal, such as eMBB service, XR service, URLLC service, mMTC service, AIoT service, etc.;

[0604] The cell state indication information is used to instruct the cell to switch between at least one state, or to switch to a second state.

[0605] Step 5: After receiving the second signal indicating the sending / receiving of a specific reference signal for waking up or triggering the specific cell, the specific cell performs at least one of the following:

[0606] Restore service status, i.e. wake up;

[0607] Enter a light sleep state;

[0608] Send SSB / SIB1;

[0609] Send downlink synchronization signal TRS;

[0610] Send positioning reference signal.

[0611] That is, it is awakened or partially awakened after receiving the second signal, or sends / receives a specific reference signal, SSB, measures CSI-RS or synchronization signal, etc.

[0612] Here, partial awakening means that the base station only sends and / or receives part of the reference signals, or switches to parameter configuration in the energy-saving state, etc. For details, please refer to the third embodiment.

[0613] In the embodiment of the present disclosure, the above-mentioned OOK / ASK / FSK / PSK signal is a low-power signal different from the OFDM signal. The processing method of the low-power signal is different from the processing method of the OFDM signal in the related technology. The cell in the sleep state or the energy-saving state can process the low-power signal, so that the terminal can communicate with the sleep cell or the cell in the energy-saving state without synchronization through the low-power signal, thereby achieving the purpose of waking up the sleep cell or triggering the sleep cell to wake up and provide services.
