Through the OOK / ASK / FSK / PSK signal, it is possible to wake up the target cell, trigger the target cell to send and / or receive a first object; trigger the target cell to switch to the first state. Since the signal transmitted between the terminal and the network-side device in the existing solution is an OFDM signal, and the network-side device in the dormant or energy-saving state cannot process the OFDM signal (such as fast Fourier transform FFT), and the above OOK / ASK / FSK / PSK signal is a low-power signal different from the OFDM signal, and the processing method of this low-power signal is different from the processing method of the existing OFDM signal. The cell in the dormant state or the energy-saving state can process this low-power signal, so that the terminal can communicate with the dormant cell or the cell in the energy-saving state without synchronization through this low-power signal, and further achieve the purpose of waking up the dormant cell or triggering the dormant cell to wake up to provide services.

[0219] Optionally, the above target cell includes at least one of a cell in a dormant state, a cell in a closed state, a cell in a sleep state, and a cell in an energy-saving state. The target cell can be a primary serving cell or a secondary cell, and the target cell has a cell identification ID.
[0220] Optionally, the above terminal includes a terminal to be served, which can be a dedicated terminal that only includes sending / receiving OFDM-based OOK / ASK / FSK / PSK signals, or a terminal that simultaneously includes sending / receiving OFDM-based OOK / ASK / FSK / PSK signals and sending / receiving NR signals. Here, the OOK / ASK / FSK / PSK uplink signal sent by the terminal can be based on a multi-carrier waveform, such as CP-OFDM, or based on a single-carrier waveform, such as DFT-S-OFDM.
[0221] Optionally, the above first target reference signal includes at least one of the following: Primary Synchronisation Signal (PSS), Secondary Synchronisation Signal (SSS), Synchronization Signal Block (SSB), CSI Reference Signal for Tracking (TRS), Positioning Reference Signal (PRS), Phase-tracking reference signal (PT-RS), random access preamble, Sounding Reference Signal (SRS), Demodulation Reference Signal (DMRS), CSI Reference Signal (CSI-RS).
[0222] Optionally, the above first 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), Physical Uplink Shared Channel (PUSCH).
[0223] Optionally, the above first signal includes signal information and indication information. The signal information includes at least one of the amplitude, frequency point, 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; triggering the target cell to switch to a first state.
[0224] The above OOK / ASK / FSK / PSK signals are low-power signals. The network-side device corresponding to the target cell can detect and process the OOK / ASK / FSK / PSK signals through envelope detection, and then through the low-power signals, the terminal can communicate with the sleeping cell or the cell in the energy-saving state without synchronization, thereby waking up the sleeping cell or triggering the sleeping cell to wake up to provide services.
[0225] In the embodiments of the present application, the terminal sends a first signal, and the first signal includes at least one of the following: OOK signal; ASK signal; FSK signal; PSK signal. Through the OOK / ASK / FSK / PSK signals, the target cell can be woken up, and the target cell can be triggered to send and / or receive a first object; the target cell can be triggered to switch to a first state. Since the signals transmitted between the terminal and the network-side device in the existing solutions are OFDM signals, and the network-side devices in the sleeping or energy-saving state cannot process the OFDM signals (such as fast Fourier transform FFT), and the above OOK / ASK / FSK / PSK signals are low-power signals different from OFDM signals, and the processing method of the low-power signals is different from that of the existing OFDM signals, the cells in the sleeping state or the energy-saving state can process the low-power signals, so that through the low-power signals, the terminal can communicate with the sleeping cell or the cell in the energy-saving state without synchronization, and then the purpose of waking up the sleeping cell or triggering the sleeping cell to wake up to provide services can be achieved.
[0226] Optionally, the first signal is a signal based on Orthogonal Frequency Division Multiplexing (OFDM), that is, the above first signal is an OFDM-based OOK / ASK / FSK / PSK signal.
[0227] When the first signal is an OFDM-based OOK / ASK / FSK / PSK signal, the architecture of the existing NR transceiver can be utilized to further avoid adding a new transceiver, thereby simplifying the complexity of the transceiver. The detection of the OOK / ASK / FSK / PSK modulation signals (i.e., the OFDM-based OOK / ASK / FSK / PSK signals) can greatly reduce the power consumption at the receiving end because it does not require an inverse Fourier transform (IFFT) operation but performs envelope, filtering, or phase detection, thereby achieving an energy-saving effect.
[0228] Optionally, the first signal carries at least one of the following:
[0229] Discover terminal-related information. For example, it can be information related to the amplitude / phase / power / energy, etc. of the signal for signal detection;
[0230] Wake up the relevant information of the target cell. For example, it includes the indication information of waking up the target cell or the cell group where the target cell is located, and the relevant information of the identifier of the target cell or the cell group where the target cell is located. The wake-up target cell indication information is used to indicate whether to wake up the target cell;
[0231] Trigger the relevant information of the target cell. For example, it includes the indication information of the target cell or the cell group where the target cell is located, and the relevant information of 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;
[0232] Trigger the relevant information of the target cell to send and / or receive a first object. For example, it includes the indication information of sending and / or receiving a first target reference signal. The indication information is used to indicate at least one of the first target reference signal and the first target channel sent or received by the target cell;
[0233] Trigger the relevant information for the target cell to switch to the first state. For example, it includes cell state indication information.
[0234] As an implementation, the above first signal carries at least one of the following:
[0235] Cell wake-up indication information, used to indicate whether to wake up the target cell;
[0236] Cell identifier-related information, used to indicate the relevant cell information for sending / receiving the wake-up or trigger signal / channel;
[0237] First object sending / receiving indication information, used to indicate the first object sent / received by the target cell;
[0238] Function trigger indication information, used to indicate the target cell to turn on or off specific functions, such as: measurement, synchronization, positioning, energy saving, access, specific service transmission, etc.;
[0239] Terminal-specific identifier, used to indicate the specific type or identifier of the terminal, such as: terminal type identifier, terminal version identifier, terminal identifier supporting specific services, indication related to whether the target cell can be woken up;
[0240] Terminal demand information-related identifier, used to indicate the current service demand of the terminal, such as: access, measurement, synchronization, positioning, energy saving, specific service transmission demand, etc.; or, indicate the current service demand of the terminal, such as: eMBB service, XR service, URLLC service, mMTC service, AIoT service, etc.
[0241] Cell state indication information, used to indicate the target cell to switch between at least two states, or switch to the first state.
[0242] In an embodiment of the present application, after receiving the above first signal, the network-side device can wake up the target cell after a certain period of time; trigger the target cell to send and / or receive a first object; trigger the target cell to switch to at least one of the first states.
[0243] When the terminal does not receive any synchronization signals sent by the target cell, such as: Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), Synchronization Signal Block (SSB), Tracking Reference Signal (TRS), etc., or when receiving synchronization signals sent by the target cell at a long 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 signals to the base station based on the existing NR signals. In an embodiment of the present application, the first signal sent by the terminal is a modulation signal based on OOK / ASK / FSK / PSK. Without precise synchronization between the base station and the terminal, the base station can detect the first signal according to relevant information such as the amplitude / power / energy / phase of the first signal, that is, the effect of discovering the terminal without precise synchronization is achieved.
[0244] Optionally, the first signal can also jointly indicate at least one of the uses of waking up the target cell; triggering the target cell to send and / or receive a first object; triggering the target cell to switch to the first state, etc. That is, when the base station detects the first signal of the terminal, it can wake up the target cell; trigger the target cell to send and / or receive a first object; trigger the target cell to switch to the first state, etc. The specific joint indication can be determined by at least one of protocol definition, pre-stored information of the terminal, core network information, and historical information of the terminal.
[0245] Optionally, when coarse synchronization can be achieved between the terminal and the base station, the first signal can further carry an indication for waking up the target cell; triggering the target cell to send and / or receive a first object; triggering the target cell to switch to a first state, etc. For example, when the first signal is in different time-domain or frequency-domain sequence patterns, it corresponds to different indication information. When the base station detects that the first signal is in 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, without the need for the base station to continuously send synchronization signals for fine synchronization to the terminal, such as SSBs with a period less than or equal to 160 ms, that is, while achieving energy saving on the network side, the base station can also be woken up according to the terminal service requirements, or be triggered to send and / or receive a first object, or switch to the signal / channel transceiver in different energy-saving states, thus not affecting the service requirements for the terminal.
[0246] When the first signal implicitly or explicitly triggers the target cell to send and / or receive a first object, it can trigger at least one of a specific reference signal and a specific channel in a targeted manner. For example, according to the service requirements, for synchronization services, the terminal needs to trigger the target cell to send SSBs and / or Tracking Reference Signals (TRS); for positioning services, it needs to trigger the target cell to send Positioning Reference Signals (PRS) and / or receive Sounding Reference Signals (SRS); for measurements, it needs to trigger the target cell to send SSBs and / or CSI Reference Signals (CSI-RS); for access, it needs to send at least one of SSBs, send preambles for random access, and receive Physical Random-Access Channels (PRACH). The base station only needs to send and / or receive the above reference signals and / or channels according to the first signal, instead of sending and / or receiving all reference signals and channels, thereby achieving energy saving on the network side.
[0247] When the first signal implicitly or explicitly triggers the target cell to switch to the first state, where 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 services state. For example: The terminal can, according to its service requirements, such as when the terminal only needs to perform RRM measurements for cell selection, at this time, the target cell only needs to be in the light sleep state and send SSB or CSI-RS with an 80ms period. The base station only needs to trigger the transmission / reception of reference signals / channels in the lightly dormant state according to the first signal, so as to achieve energy saving of the base station while meeting the service requirements of the terminal.
[0248] Optionally, the method of the embodiment of the present application further includes:
[0249] Obtaining a first response signal of the first signal.
[0250] In the embodiment of the present application, the base station detects the first signal, and when the signal information of the first signal meets the first condition, sends a first response signal of the first signal. For example, when the signal information of the first signal meets a specific threshold or a specific value, the base station sends the above first response signal.
[0251] Optionally, the first response signal carries at least one of the following:
[0252] Confirmation information of the first signal; this confirmation information can be an OOK / ASK / FSK / PSK signal, for example, an OOK / ASK / FSK / PSK signal based on OFDM;
[0253] Feedback information of the first signal; this feedback information can be an OOK / ASK / FSK / PSK signal, for example, an OOK / ASK / FSK / PSK signal based on OFDM;
[0254] A first reference signal and / or a first channel; the first reference signal is a reference signal for subsequent determination of whether the terminal wakes up a dormant cell or a reference signal providing a specific function for the terminal. For example, the specific function can be functions such as synchronization, measurement, or positioning. The reference signal can 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.
[0255] Cell information of the cell sending the first response signal, such as cell identification information.
[0256] Optionally, the first response signal can be sent by at least one base station that receives the first signal.
[0257] For the feedback information or confirmation information where the first response signal is the first signal, in order to prevent the base station from being woken up 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, which affects the energy-saving gain of the base station. After detecting the first signal, the base station can determine whether to be woken up, or be triggered to send / receive signals, or be triggered to switch to the first state of the cell for confirmation or feedback according to the internal implementation algorithm, and further indicate whether the terminal wakes up the cell, or whether to trigger the sending / receiving of signals, or whether to trigger the switching to the first state of the cell, or whether the first signal is received. On the one hand, it reduces the unconditional wake-up of the base station, and on the other hand, it reduces the continuous sending of the first signal by the terminal, so that both sides have the same understanding.
[0258] For the first response signal being the first reference signal and / or the first channel, for example: after the base station detects the first signal, it sends the first reference signal, such as: PSS, SSS, TRS, SSB, etc., and receives channels such as PRACH and the PDCCH where Paging is located, which can be used for subsequent communication behaviors of the terminal, such as: synchronization, RRM measurement, cell access, random access, and paging, etc. After sending the first signal, the terminal receives and / or sends the first reference signal and / or the first channel at specific time intervals. After receiving the response signal sent by at least one cell, the terminal selects a target cell to provide services for the terminal through a specific algorithm, such as: the cell selection process. If there is no terminal access in other cells that send the response signal within a specific time period, they can enter the sleep state. If the terminal only receives the response signal sent by one cell, then the current cell is used as the target cell and the terminal accesses the target cell. This method does not require the cell to be in the service state all the time, thus reducing the energy consumption on the network side. The terminal can also access the target cell by detecting the first reference signal and / or the first channel sent / received by the target cell to obtain the services provided by the target cell and reduce the impact on service performance.
[0259] In addition, when the terminal can further synchronize with the target cell while synchronizing with the network side by receiving the first response signal, it provides the preconditions for sending and receiving at least one of the triggered target reference signal, target channel, sending target indication information, the second signal, etc., that is: the transceiver sides are synchronized.
[0260] Optionally, the method of the embodiment of the present application further includes:
[0261] Sending a second signal 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, where the second object includes at least one of a second target reference signal and a second target channel.
[0262] Optionally, the above-mentioned second target reference signal includes at least one of the following: Primary Synchronisation Signal (PSS), Secondary Synchronisation Signal (SSS), Synchronization Signal Block (SSB), TRS, Positioning Reference Signal (PRS), Phase-tracking reference signal (PT-RS), random access preamble, Sounding Reference Signal (SRS), Demodulation Reference Signal (DMRS), CSI Reference Signal (CSI-RS).
[0263] Optionally, the above-mentioned 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), Physical Uplink Shared Channel (PUSCH).
[0264] In the embodiments of the present application, the terminal may determine, based on the above first response signal, which target cell to send the second signal to. That is, the specific cell is one or more cells among the above target cells. Specifically, the terminal may randomly determine one or more cells (i.e., the above specific cells) among the target cells that send the first response signal, or may determine one or more cells (i.e., the above specific cells) among the target cells that send the first response signal in other ways.
[0265] Optionally, the second signal carries at least one of the following:
[0266] Wake up specific cell - related information;
[0267] Trigger specific cell - related information;
[0268] Trigger the specific cell to send and / or receive information related to the second object;
[0269] Trigger the specific cell to switch to the second state - related information.
[0270] As an implementation, the above - mentioned second signal carries at least one of the following:
[0271] Cell wake - up indication information, used to indicate whether to wake up a specific cell;
[0272] Cell identity - related information, used to indicate the relevant cell information for sending / receiving the wake - up or trigger signal / channel;
[0273] Second - object sending / receiving indication information, used to indicate the second object that the specific cell sends / receives;
[0274] Function - trigger indication information, used to indicate whether the specific cell enables or disables specific functions, such as: measurement, synchronization, positioning, energy saving, access, specific service transmission, etc.;
[0275] Terminal - specific identification, used to indicate the specific type or identification of the terminal, such as: terminal type identification, terminal version identification, terminal identification supporting specific services, indication related to whether the target cell can be woken up;
[0276] Terminal - demand - information - related identification, used to indicate the current service demand of the terminal, such as: access, measurement, synchronization, positioning, energy - saving, specific - service - transmission demand, etc.; or, to indicate the current service demand of the terminal, such as: eMBB service, XR service, URLLC service, mMTC service, AIoT service, etc.;
[0277] Cell - state indication information, used to indicate that the specific cell switches between at least two states or switches to the second state.
[0278] When the terminal sends the first signal, the terminal can also send a second signal, which can further provide additional information for the base station. The additional information includes at least one of the following: enhancement or supplementary information of the first signal, that is: information to improve the reception performance of the first signal, or provide supplementary information of the first signal.
[0279] Regarding the information of the second signal used to improve the reception performance of the first signal, for example: the second signal is a repeated signal of the first signal, or the second signal carries information related to the first signal, but the first signal and the second signal are two different signals. The terminal sending the second signal can improve the performance of the base station to discover the terminal and obtain the information carried by the first signal and / or the second signal.
[0280] For the second signal to provide supplementary information for the first signal, for example: the first signal is broadcast based on the terminal being out of sync or not precisely synchronized with the base station, serving as a signal for the base station to discover the terminal. The second signal can be sent as supplementary information of the terminal, such as: the version or type of the terminal, enabling the target cell that can serve the terminal to discover it. After the base station detects the first signal, it detects the second signal. If the cell can serve the terminal, then the cell is awakened as the target cell and is triggered to send or receive a second object; trigger at least one of the switches to the second state. In this way, by sending the second signal, the accuracy of awakening or triggering the target cell can be improved, and the network energy-saving performance can be enhanced.
[0281] After the terminal receives the first response signal, it sends a second signal to further indicate awakening the target cell, triggering the target cell to send or receive a second object; trigger at least one of the switches of the target cell to the second state. Here, when the terminal receives the first response signal, such as: for synchronization signals PSS, SSS, TRS, SSB, etc., the terminal can synchronize with the base station. By sending the second signal, the terminal can carry indication information for the target cell to awaken the target cell, trigger the target cell to send or receive a second object; trigger at least one of the switches of the target cell to the second state. Here, the target cell can be specifically indicated by the second signal, or implicitly indicated by the second signal having a specific association relationship with the response signal sent by the target cell. Here, the target cell can send a synchronization signal according to the terminal service requirements, and then obtain more accurate indication information, such as: relevant indication information for being awakened by the terminal, or relevant indication information for triggering the sending or receiving of a second object; or at least one of the relevant indication information for triggering the switch to a specific cell state, without always being in the case of providing a synchronization signal with the terminal, thereby achieving energy saving on the network side.
[0282] Optionally, the second signal can also jointly indicate uses such as awakening a specific cell; triggering a specific cell to send and / or receive a second object; triggering a specific cell to switch to the second state, etc., that is, when the base station detects the second signal of the terminal, it can awaken a specific cell; trigger a specific cell to send and / or receive a second object; trigger a specific cell to switch to the second state, etc. The specific joint indication can be determined by at least one of protocol definition, pre-stored information of the terminal, core network information, terminal historical information, etc.
[0283] Optionally, when the terminal can achieve rough synchronization with the base station, the second signal can further carry an indication message for waking up a specific cell; triggering the specific cell to send and / or receive a second object; triggering the specific cell to switch to a second state, etc. For example, when the second signal is in different time-domain or frequency-domain sequence patterns, it corresponds to different indication messages. When the base station detects that the second signal is in a specific time-domain or frequency-domain sequence pattern, it obtains the corresponding indication message, and then sends and / or receives at least one of a specific reference signal and a specific channel. In this way, when the base station does not need to continuously send synchronization signals for fine synchronization to the terminal, such as SSBs with a period less than or equal to 160 ms, that is, when the base station achieves energy saving on the network side, it can also be woken up according to the terminal service requirements, or be triggered to send and / or receive a second object, or switch to the signal / channel transceiver in different energy-saving states, thus not affecting the service requirements for the terminal.
[0284] When the second signal implicitly or explicitly triggers the specific cell to send and / or receive a second object, it can trigger at least one of a specific reference signal and a specific channel in a targeted manner. For example, according to the service requirements, for synchronization services, the terminal needs to trigger the target cell to send SSBs and / or Tracking Reference Signals (TRS); for positioning services, the terminal needs to trigger the target cell to send Positioning Reference Signals (PRS) and / or receive Sounding Reference Signals (SRS); for measurements, the terminal needs to trigger the target cell to send SSBs and / or CSI Reference Signals (CSI-RS); for access, the terminal needs to send at least one of SSBs, send preambles for random access, and receive Physical Random-Access Channels (PRACH). The base station only needs to send and / or receive the above reference signals and / or channels according to the second signal, instead of sending and / or receiving all reference signals and channels, thereby achieving energy saving on the network side.
[0285] When the second signal implicitly or explicitly triggers the target cell to switch to the second state, where 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 services state. For example, the terminal can, according to its service requirements, such as when the terminal only needs to perform RRM measurements for cell selection, at this time, the target cell only needs to be in a light sleep state and send SSB or CSI-RS with an 80ms period. The base station only needs to trigger the transmission / reception of reference signals / channels in the lightly dormant state according to the second signal, so as to achieve base station energy saving while meeting the service requirements of the terminal.
[0286] Optionally, the method of the embodiment of the present application further includes:
[0287] Obtain a second response signal, 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.
[0288] In the embodiment of the present application, the base station can send a first response signal after receiving the first signal and send a second response signal after receiving the second signal, or can also send the above-mentioned second response signal after receiving the first signal and the second signal.
[0289] Optionally, the second response signal carries at least one of the following:
[0290] Confirmation information for the target signal; this confirmation information can be an OOK / ASK / FSK / PSK signal, for example, an OOK / ASK / FSK / PSK signal based on OFDM;
[0291] Feedback information for the target signal; this feedback information can be an OOK / ASK / FSK / PSK signal, for example, an OOK / ASK / FSK / PSK signal based on OFDM;
[0292] A second reference signal or a second channel; this second reference signal is a reference signal for the subsequent terminal to wake up a dormant cell or a reference signal for providing a specific function for the terminal. For example, this specific function can be functions such as synchronization, measurement, or positioning. The reference signal can be an SSB, CSI-RS, TRS, random access preamble, etc. The second channel includes a downlink control channel and / or an uplink control channel.
[0293] Cell information of the cell sending the second response signal. Such as cell identification information.
[0294] Optionally, the second response signal can be sent by the target cell that receives the second signal.
[0295] For the feedback information or confirmation information where the second response signal is the second signal, in order to prevent the base station from being woken up by the terminals of each second signal, or being triggered to send and / or receive signals, or being triggered to switch to the second cell state, which affects the energy-saving gain of the base station. After detecting the second signal, the base station can determine whether to be woken up according to the internal implementation algorithm, or be explicitly indicated by the second signal whether to be woken up, or be triggered to send / receive signals, or be triggered to switch to the second cell state for confirmation or feedback, further indicating whether the terminal wakes up the cell, or whether to trigger the sending / receiving of signals, or whether to trigger the switching to the second cell state, or whether the second signal is received. On the one hand, it reduces the unconditional wake-up of the base station, and on the other hand, it responds to the sending of the second signal by the terminal, so that both parties have the same understanding.
[0296] For the second response signal being the second reference signal and / or the second channel, for example: after detecting the second signal, the base station sends the second reference signal, such as: PSS, SSS, TRS, SSB, etc., and receives channels such as PRACH, PDCCH where Paging is located, which can be used for 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 within a specific time period after receiving the second response signal. After the terminal receives the response signal, the target cell provides services 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 the sleep state and does not need to be in the service state all the time, thereby reducing the energy consumption on the network side.
[0297] Optionally, the method of the embodiment of the present application further includes:
[0298] At a first moment, receive and / or send a first specific reference signal and / or a first specific channel in a first specific cell in the RRC idle state or the RRC inactive state;

[0345] The generation methods of OOK / ASK / FSK / PSK signals will be described below in conjunction with Embodiment 1.
[0346] Embodiment 1: Generation methods of OOK / ASK / FSK / PSK signals based on OFDM;
[0347] As Figure 3 and Figure 4 shown, the transmitter for transmitting the first signal and / or the second signal by the terminal may be an independent transmitter from the transmitter of the uplink NR signal, or the same transmitter.
[0348] The receiver for receiving the first signal and / or the second signal by the base station may be an independent receiver from the receiver of the uplink NR signal, or the same receiver.
[0349] The generation method of multi-carrier amplitude shift keying (MC-ASK), such as on-off keying (OOK) signals based on OFDM, will be described below:
[0350] According to the number of bits of ASK and the frequency domain resources / number of points of inverse fast Fourier transform (IFFT) occupied by each bit, the waveform generation of MC-ASK may include the following four optional waveform generation methods:
[0351] Method 1:
[0352] OOK-1: As Figure 5 shown, the low power wake up signal (LP-WUS) includes N sub-carriers (SC). After performing inverse fast Fourier transform (IFFT) and adding a cyclic prefix (CP) operation on the LP-WUS, one OFDM symbol corresponds to a single bit.
[0353] The sub - carriers (SCs) of the Low Power Wake Up Signal (LP - WUS) are as follows:
[0354] OOK = 1 means that all SCs are used for modulation, corresponding to bit "1", or any one or several of the K - order modulation symbols corresponding to bit "1";
[0355] OOK = 0 means that all SCs have zero power (from the perspective of the baseband), corresponding to bit "0", or any one or several of the K - order modulation symbols corresponding to bit "0".
[0356] When the first signal is an OOK - 1 signal, this 1 - bit information can be used to trigger the signal of 1 OFDM symbol. In order for the base - station side to detect the terminal, this signal can be repeatedly transmitted N times. The base - station side receiver can continuously detect or detect the user's signal during a specific time period. The specific detection method depends on the base - station implementation or on the relevant information of the terminal sending the first signal.
[0357] Method 2:
[0358] OOK - 2: Parallel M - bits OOK in the frequency domain.
[0359] The N SCs of LP - WUS are further divided into M segments, each segment containing N / 2 sub - carriers, as Figure 6 shown Figure 6 where M = 2, and there may be guard bands in between and / or around. After performing the Inverse Fast Fourier Transform (IFFT) and adding a Cyclic Prefix (CP) operation on this LP - WUS, this LP - WUS corresponds to parallel M - bits OOK in the frequency domain. The SCs of LP - WUS are:
[0360] OOK = 1 indicates that all SCs in the segment have been modulated, corresponding to bit "1", or any one or several of the K - order modulation symbols corresponding to bit "1";
[0361] OOK = 0 indicates that all SCs in the segment are of zero power (from the perspective of the baseband), corresponding to bit "0", or any one or several of the K - order modulation symbols corresponding to bit "0".
[0362] When the first signal is an OOK-2 signal, M bits in the frequency domain can carry the terminal discovery signal. For example, the first signal is a specific sequence, such as M bits of 1. The base station can detect the terminal based on a sequence of a specific pattern, such as "1010…1". The receiver on the base station side can continuously detect or detect the user's signal within a specific time period. The specific detection method depends on the base station implementation or on the relevant information of the first signal sent by the terminal.
[0363] Method 3:
[0364] OOK-3: Multi-tone single-bit OOK;
[0365] The Low Power Wake Up Signal (LP-WUS) includes N subcarriers (SCs). The N SCs of the LP-WUS are divided into L segments, as Figure 7 shown, Figure 7 where L = 2. There is no guard band between the segments, but there may be a guard band around the segments. After performing the Inverse Fast Fourier Transform (IFFT) and adding a Cyclic Prefix (CP) operation on this LP-WUS, a Multi-tone single-bit OOK is obtained. Figure 7 The t0 and t1 in
[0366] represent sequences corresponding to 0 and 1 respectively. The SCs of the LP-WUS are:
[0367] OOK = 1 means that 1 subcarrier (known to the UE) in each segment is modulated, and the rest of the SCs have zero power (from the perspective of the baseband), corresponding to the bit "1";
[0368] OOK = 0 means that all SCs in all segments have zero power (from the perspective of the baseband), corresponding to the bit "0".
[0369] Method 4: Time-domain transformed M-bit OOK;
[0370] The N SCs of OOK-4 are generated by transformation (DFT / least squares);
[0371] As Figure 8 shown, N' samples are generated by M bits, and N SCs of LP-WUS are generated by transformation (DFT / least squares); signal modulation can be used or not; truncation or other additional modulation can be used, or other additional modulation can be not used. If other additional modulation is not used, N is the same as N'. After performing the Inverse Fast Fourier Transform (IFFT) and adding a Cyclic Prefix (CP) operation on this LP-WUS, OOK-4 is obtained.
[0372] OOK-4 can be considered as an example of an OOK signal based on a single carrier (such as DFT-S-OFDM), or can be used as a signal generation method independent of the uplink single carrier (such as DFT-S-OFDM).
[0373] The first signal / second signal can also be a multi-carrier FSK signal of M bits, and specific examples are as follows:
[0374] FSK-1: N SCs are divided into M pairs of segments, where M is an integer greater than or equal to 1, as Figure 9 shown (M = 2) and as Figure 10 shown (M = 4). There are potential guard bands in between and around; one segment includes one subcarrier or multiple consecutive SCs; in a pair of segments, one segment is modulated and the other segment has zero power (from the perspective of the baseband).
[0375] FSK-2: N SCs are divided into 2 M segments, where M is an integer greater than or equal to 0, as Figure 11 shown, M = 1, that is, N SCs are divided into 2 segments, as Figure 12 shown, M = 2, that is, N SCs are divided into 4 segments, and there are potential guard bands in between and around. One segment includes one subcarrier or multiple consecutive SCs; one of the 2^M segments is modulated and the other segments of the SCs have zero power (from the perspective of the baseband).
[0376] The first signal / second signal can also be based on CP-OFDM, which can multiplex existing NR synchronization signals and can provide a high data transmission rate. Further, since the LP-WUR CP-OFDM signal and NR transmission are orthogonal, the requirement for the guard bandwidth between them can be relaxed.
[0377] In the embodiments of the present application, when the functions of the first signal and / or the second signal are different, their transceivers (transceiver) are different.
[0378] For example:
[0379] 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 and the transceiver of NR are independent of each other. Among them, the first signal at least includes OFDM-based OOK / ASK / FSK / PSK signals.
[0380] When the first signal / second signal is a trigger signal (i.e., the first signal or the 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 perform a state switch), the transceiver of the first signal or the second signal and the transceiver of NR are independent of each other, or can be the same transceiver as the transceiver of NR. Among them, the trigger signal at least includes OFDM-based OOK / ASK / FSK / PSK signals.
[0381] 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 transceiver as the transceiver of NR.
[0382] In the embodiments of the present application, when the receiver of the first signal and / or the second signal can be an independent receiver from the receiver of the uplink NR signal, the network-side base station does not need to keep the corresponding receiver of NR turned on all the time, and only needs to detect the first signal and / or the second signal. The receiver of this signal only requires 1 / 10 of the power consumption of the NR receiver to achieve energy saving on the network side.
[0383] 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 implement the function of the base station discovering the terminal only through a low-power transmitter.
[0384] When the transmitter of the first signal and / or the second signal is a different transmitter 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. Therefore, the purpose of reducing the power consumption of the terminal can be achieved.
[0385] When the first signal and / or the second signal is an OFDM-based OOK / ASK / FSK / PSK modulation signal, the existing architecture of the NR transceiver 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 at the receiving end, thereby achieving the effect of energy saving.
[0386] As Figure 13 shown, the embodiments of the present application also provide an information processing method, which is executed by a network-side device, and the method includes:
[0387] Step 1301: Receive a first signal for at least one of the following:
[0388] Discover a terminal; wake up a target cell; trigger the target cell to send or receive a first object; trigger the target cell to switch to a first state; where the first object includes at least one of a first target reference signal and a first target channel;
[0389] Where the first signal includes at least one of the following: On-Off Keying (OOK) signal; Amplitude Shift Keying (ASK) signal; Frequency Shift Keying (FSK) signal; Phase Shift Keying (PSK) signal.
[0390] Optionally, the above network-side device includes the base station where the target cell is located, and can transmit and / or receive OFDM-based OOK / ASK / FSK / PSK signals and / or NR signals.
[0391] Optionally, the first signal can be received based on a dedicated receiver for the first signal, or can be received through an NR receiver.
[0392] Optionally, the above target cell can continuously receive and detect the first signal, or can periodically receive and detect the first signal, or can semi-continuously receive and detect the first signal. The specific receiving algorithm can be determined by the internal algorithm of the target cell.
[0393] Optionally, the above target cell includes at least one of a cell in a dormant state, a cell in a closed state, a cell in a sleep state, and a cell in an energy-saving state. The target cell can be a primary serving cell or a secondary cell, and the target cell has a cell identification ID.
[0394] Optionally, the above first signal includes signal information and indication information, and the signal information includes at least one of the amplitude, frequency point, 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; triggering the target cell to switch to a first state.
[0395] The above OOK / ASK / FSK / PSK signal is a low-power signal. The network-side device can detect and process the OOK / ASK / FSK / PSK signal by envelope detection, and then through this low-power signal, the terminal can 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 to provide services.
[0396] In the embodiments of the present application, the above OOK / ASK / FSK / PSK signals are low-power signals different from OFDM signals. The processing method of the low-power signals is different from that of existing OFDM signals. A cell in a dormant state or an energy-saving state can process the low-power signals, so that the terminal can communicate with the dormant cell or the cell in the energy-saving state without synchronization through the low-power signals, thereby achieving the purpose of waking up the dormant cell or triggering the dormant cell to wake up to provide services.
[0397] Optionally, the first signal is a signal based on orthogonal frequency division multiplexing (OFDM), that is, the above first signal is an OFDM-based OOK / ASK / FSK / PSK signal.
[0398] When the first signal is an OFDM-based OOK / ASK / FSK / PSK signal, the architecture of the existing NR transceiver can be utilized to further avoid adding a new transceiver, thereby simplifying the complexity of the transceiver. For the signal detection based on OOK / ASK / FSK / PSK modulation, since the inverse Fourier transform (IFFT) operation is not required and envelope, filtering or phase detection is performed, the power consumption at the receiving end can be greatly reduced, thereby achieving the effect of energy saving.
[0399] Optionally, the first signal carries at least one of the following:
[0400] Terminal-related information is discovered. For example, it can be information related to the amplitude / phase / power / energy, etc. of the signal for signal detection;
[0401] Wake-up target cell-related information. For example, it includes wake-up target cell indication information or information related to the cell group where the target cell is located and the identifier of the target cell or the cell group where the target cell is located. The wake-up target cell indication information is used to indicate whether to wake up the target cell;
[0402] Trigger target cell-related information; for example, it includes 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;
[0403] Information related to triggering the target cell to send and / or receive a first object. For example, it includes indication information for sending and / or receiving a first target reference signal, and the indication information is used to indicate at least one of the first target reference signal and the first target channel sent or received by the target cell;
[0404] Information related to triggering the target cell to switch to a first state. For example, it includes cell state indication information.
[0405] As an implementation manner, the above first signal carries at least one of the following:
[0406] Wake-up cell indication information, used to indicate whether to wake up the target cell;
[0407] Cell identification related information, used to indicate the relevant cell information for sending / receiving a wake-up or trigger signal / channel;
[0408] First object transmission / reception indication information, used to indicate the first object transmitted / received by the target cell;
[0409] Function trigger indication information, used to indicate enabling or disabling a specific function of the target cell, such as: measurement, synchronization, positioning, access, energy saving, specific service transmission, etc.;
[0410] Terminal specific identification, used to indicate the specific type or identification of the terminal, such as: terminal type identification, terminal version identification, terminal identification supporting specific services, indication related to whether the target cell can be woken up;
[0411] Terminal demand information related identification, used to indicate the current service demand of the terminal, such as: access, measurement, synchronization, positioning, energy saving, specific service transmission demand, etc.; or, indicate the current service demand of the terminal, such as: eMBB service, XR service, URLLC service, mMTC service, AIoT service, etc. Cell status indication information, used to indicate that the target cell switches between at least two states, or switches to the first state.
[0412] In the embodiments of the present application, the network-side device can wake up the target cell after receiving the above 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 the first state.
[0413] When the terminal does not receive any synchronization signals sent by the target cell, such as: Primary Synchronisation Signal (PSS), Secondary Synchronisation Signal (SSS), Synchronization Signal Block (SSB), etc., or when receiving synchronization signals sent by the target cell at a long time interval, such as: PSS, SSS, SSB, etc., the terminal cannot achieve synchronization or fine synchronization with the base station, then the terminal cannot send any signals to the base station based on the existing NR signals. In the embodiments of the present application, the first signal sent by the terminal is a modulation signal based on OOK / ASK / FSK / PSK. Without precise synchronization between the base station and the terminal, the base station can detect the first signal according to relevant information such as the amplitude / power / energy / phase of the first signal, that is, the effect of discovering the terminal without precise synchronization is achieved.
[0414] Optionally, the first signal may also jointly indicate uses such as waking up the target cell; triggering the target cell to send and / or receive a first object; triggering the target cell to switch to a first state, etc. That is, when the base station detects the first signal of the terminal, it can wake up the target cell; trigger the target cell to send and / or receive a first object; trigger the target cell to switch to a first state, etc. The specific joint indication can be determined by at least one of protocol definition, pre-stored information of the terminal, core network information, terminal historical information, etc.
[0415] Optionally, when the terminal can achieve coarse synchronization with the base station, the first signal can further carry indication information such as waking up the target cell; triggering the target cell to send and / or receive a first object; triggering the target cell to switch to a first state, etc. For example: when the first signal is in different time domain or frequency domain sequence patterns, it corresponds to different indication information. When the base station detects that the first signal is in 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, when the base station does not need to continuously send synchronization signals for fine synchronization to the terminal, such as SSBs with a period less than or equal to 160 ms, that is, when the base station achieves energy saving on the network side, it can still be woken up according to the terminal service requirements, or be triggered to send and / or receive a first object, or switch to the signal / channel transceiver in different energy-saving states, so as not to affect the service requirements for the terminal.
[0416] When the first signal implicitly or explicitly triggers the target cell to send and / or receive a first object, it can trigger at least one of a specific reference signal and a specific channel in a targeted manner. For example: according to the service requirements, the synchronization service needs to trigger the target cell to send SSBs and / or Tracking Reference Signals (TRS), the positioning service needs to trigger the target cell to send Positioning Reference Signals (PRS) and / or receive Sounding Reference Signals (SRS), the measurement needs to trigger the target cell to send SSBs, send preambles for random access, and / or CSI Reference Signals (CSI-RS), and the access needs to send SSBs and receive Physical Random-Access Channels (PRACH), etc. The base station only needs to send and / or receive the above reference signals and / or channels according to the first signal, instead of sending and / or receiving all reference signals and channels, thus achieving energy saving on the network side.
[0417] When the first signal implicitly or explicitly triggers the target cell to switch to the first state, where 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 services state. For example, the terminal can, according to its service requirements, such as when the terminal only needs to perform RRM measurements for cell selection, at this time, the target cell only needs to be in the light sleep state and send SSB or CSI-RS with a period of 80 ms. The base station only needs to trigger the transmission / reception of reference signals / channels in the lightly dormant state according to the first signal, so as to achieve energy saving of the base station while meeting the service requirements of the terminal.
[0418] Optionally, after receiving the first signal, the method further includes:
[0419] Sending a first response signal to the first signal.
[0420] Optionally, the sending of the first response signal to the first signal includes:
[0421] When the signal information of the first signal meets the first condition, sending a first response signal to the first signal;
[0422] Wherein, the signal information includes at least one of the amplitude, frequency point, carrier, bandwidth, phase, power and energy of the first signal.
[0423] For example, the base station performs first signal detection, obtains the M-bit information carried by the first signal, 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, it sends a first response signal.
[0424] Optionally, the method of the embodiment of the present application further includes:
[0425] When the signal information of the first signal meets the first condition, perform at least one of the following:
[0426] Discover the terminal; wake up the target cell; trigger the target cell to send or receive a first object; trigger the target cell to switch to the first state;
[0427] Wherein, the signal information includes at least one of the amplitude, frequency point, carrier, bandwidth, phase, power and energy of the first signal.
[0428] Optionally, the first response signal carries at least one of the following:
[0429] Confirmation information for the first signal; the confirmation information may be an OOK / ASK / FSK / PSK signal, such as an OFDM-based OOK / ASK / FSK / PSK signal;
[0430] Feedback information for the first signal; the feedback information may be an OOK / ASK / FSK / PSK signal, such as an OFDM-based OOK / ASK / FSK / PSK signal;
[0431] The first reference signal and / or the first channel; the first reference signal is a reference signal for subsequent terminals to wake up a dormant cell or a reference signal for providing specific functions for the terminals. For example, the specific functions may be functions such as synchronization, measurement, or positioning. 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.
[0432] Cell information of the cell that sends the first response signal, such as cell identification information.
[0433] Optionally, the first response signal may be sent by at least one base station that receives the first signal.
[0434] For the first response signal being the feedback information or confirmation information of the first signal, in order to avoid the base station being woken up 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, which affects the energy-saving gain of the base station. After detecting the first signal, the base station can judge whether to be woken up, or be triggered to send / receive signals, or be triggered to switch to the first state of the cell for confirmation or feedback according to the internal implementation algorithm, and further indicate whether the terminal wakes up the cell, or whether to trigger the sending / receiving of signals, or whether to trigger the switching to the first state of the cell, or whether the first signal is received. On the one hand, it reduces the unconditional wake-up of the base station, and on the other hand, it reduces the continuous sending of the first signal by the terminal, so that both parties have the same understanding.
[0435] For the first response signal being the first reference signal and / or the first channel, for example: after the base station detects the first signal, it sends the first reference signal, such as: PSS, SSS, TRS, SSB, etc., and receives the channels where PRACH and Paging are located, such as PDCCH, etc., which can be used for the terminal to perform subsequent communication behaviors, such as: synchronization, RRM measurement, cell access, random access, and paging, etc. After the terminal sends the first signal, it receives and / or sends the first reference signal and / or the first channel at a specific time interval. After the terminal receives the response signal sent by at least one cell, through a specific algorithm, such as: the cell selection process, it selects a target cell to provide services for the terminal. If there is no terminal access to the other cells sending the response signal within a specific time period, they can enter the sleep state. If the terminal only receives the response signal sent by one cell, then the current cell is used as the target cell and the terminal accesses the target cell. This method does not require the cell to be in the service state all the time, thus reducing the energy consumption on the network side. The terminal can also access the target cell by detecting the first reference signal and / or the first channel sent / received by the target cell, so as to obtain the services provided by the target cell and reduce the impact on service performance.
[0436] In addition, when the terminal can further synchronize with the target cell while achieving synchronization with the network side by receiving the first response signal, it provides the preconditions for sending and receiving at least one of the target reference signal, the target channel, the sending target indication information, the second signal, etc. triggered by it, that is: the transceiver parties are synchronized.
[0437] Optionally, the method of the embodiment of the present application further includes:
[0438] Obtain a second signal, where the second signal is used for at least one of the following: waking up a specific cell; triggering a specific cell to send or receive a second object; triggering a specific cell to switch to a second state, where the second object includes at least one of a second target reference signal and a second target channel.
[0439] In the embodiment of the present application, the terminal can determine which target cell to send the second signal based on the above first response signal. That is, the specific cell is one or more of the above target cells. Specifically, the terminal can randomly determine one or more cells (i.e., the above specific cells) among the target cells that send the first response signal, or can also determine one or more cells (i.e., the above specific cells) among the target cells that send the first response signal in other ways.
[0440] Optionally, the second signal carries at least one of the following:
[0441] Information related to waking up a specific cell;
[0442] Information related to triggering a specific cell;
[0443] Trigger a specific cell to send and / or receive information related to a second object;
[0444] Trigger information related to a specific cell to switch to a second state.
[0445] As an implementation, the above second signal carries at least one of the following:
[0446] Wake-up cell indication information for indicating whether to wake up a specific cell;
[0447] Cell identity related information for indicating the relevant cell information for waking up or triggering the transmission / reception of a signal / channel;
[0448] Second object transmission / reception indication information for indicating the second object transmitted / received by a specific cell;
[0449] Function trigger indication information for indicating to enable or disable a specific function of a specific cell, such as: measurement, synchronization, positioning, energy saving, access, specific service transmission, etc.;
[0450] Terminal specific identification for indicating a specific type of terminal or terminal identification; such as: terminal type identification, terminal version identification, terminal identification supporting a specific service, indication related to whether the target cell can be woken up;
[0451] Terminal requirement information related identification for indicating the current service requirements of the terminal, such as: access, measurement, synchronization, positioning, energy saving, access, specific service transmission requirements, etc.; or, indicating the current service requirements of the terminal, such as: eMBB service, XR service, URLLC service, mMTC service, AIoT service, etc.;
[0452] Cell state indication information for indicating that a specific cell switches between at least two states or switches to a second state.
[0453] When the terminal sends the first signal, the terminal can also send a second signal, which can further provide additional information for the base station. The additional information includes at least one of the following: enhanced or supplementary information of the first signal, that is: information for improving the reception performance of the first signal, or providing supplementary information of the first signal.
[0454] For the information of the second signal used to improve the reception performance of the first signal, such as: the second signal is a repeated signal of the first signal, or the second signal carries information related to the first signal, but the first signal and the second signal are two different signals. The terminal sending the second signal can improve the performance of the base station to discover the terminal and obtain the information carried by the first signal and / or the second signal.
[0455] For the second signal to provide supplementary information for the first signal. For example, the first signal is broadcast based on the terminal being out of sync or not precisely synchronized with the base station, serving as the signal for the base station to discover the terminal. The second signal can be sent as supplementary information of the terminal, such as the version or type of the terminal, enabling the target cell that can serve the terminal to discover it. After detecting the first signal, the base station detects the second signal. If the cell can provide services for the terminal, then the cell is awakened as the target cell and is triggered to send or receive a second object; or at least one of the triggers to switch to a second state. In this way, by sending the second signal, the accuracy of awakening or triggering the target cell can be improved, and the network energy-saving performance can be enhanced.
[0456] After receiving the first response signal, the terminal sends a second signal to further indicate awakening the target cell, triggering the target cell to send or receive a second object; or at least one of the triggers to switch the target cell to a second state. Here, when the terminal receives the first response signal, such as for synchronization signals PSS, SSS, TRS, SSB, etc., the terminal can synchronize with the base station. By sending the second signal, the terminal can carry indication information for the target cell, used to awaken the target cell, trigger the target cell to send or receive a second object; or at least one of the triggers to switch the target cell to a second state. Here, the target cell can be specifically indicated by the second signal, or implicitly indicated by the second signal that has a specific association relationship with the response signal sent by the target cell. Here, the target cell can send a synchronization signal according to the terminal service requirements, and then obtain more accurate indication information, such as the relevant indication information for being awakened by the terminal, or the relevant indication information for triggering the sending or receiving of a second object; or at least one of the relevant indication information for triggering the switch to a specific cell state, without having to always be in the case of providing a synchronization signal with the terminal, thus achieving energy saving on the network side.
[0457] Optionally, the second signal can also jointly indicate at least one of the uses of awakening a specific cell; triggering the specific cell to send and / or receive a second object; triggering the specific cell to switch to a second state, that is, when the base station detects the second signal of the terminal, it can awaken the specific cell; trigger the specific cell to send and / or receive a second object; trigger the specific cell to switch to a second state, etc. The specific joint indication can be determined by at least one of protocol definition, pre-stored information of the terminal, core network information, terminal historical information, etc.
[0458] Optionally, when coarse synchronization can be achieved between the terminal and the base station, the second signal can further carry an indication message for waking up a specific cell; triggering the specific cell to send and / or receive a second object; triggering the specific cell to switch to a second state, etc. For example, when the second signal is in different time-domain or frequency-domain sequence patterns, different indication messages correspond. When the base station detects that the second signal is in a specific time-domain or frequency-domain sequence pattern, it obtains the corresponding indication message, and then sends and / or receives at least one of a specific reference signal and a specific channel. In this way, when 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 less than or equal to 160 ms, that is, when the base station achieves energy saving on the network side, it can still be woken up according to the terminal service requirements, or be triggered to send and / or receive a second object, or switch to the signal / channel transceiver in different energy-saving states, so as not to affect the service requirements for the terminal.
[0459] When the second signal implicitly or explicitly triggers the 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 the service requirements, for synchronization service, the target cell needs to be triggered to send an SSB and / or a Tracking Reference Signal (TRS); for positioning service, the target cell needs to be triggered to send a Positioning Reference Signal (PRS) and / or receive a Sounding Reference Signal (SRS); for measurement, the target cell needs to be triggered to send an SSB and / or a CSI Reference Signal (CSI-RS); for access, at least one of sending an SSB, sending a preamble of random access, and receiving a Physical Random-Access Channel (PRACH) is required. The base station only needs to send and / or receive the above reference signals and / or channels according to the second signal, instead of sending and / or receiving all reference signals and channels, thus achieving energy saving on the network side.
[0460] When the second signal implicitly or explicitly triggers the target cell to switch to the second state, where 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 services state. For example: The terminal can, according to its service requirements, such as when the terminal only needs to perform RRM measurements for cell selection, at this time, the target cell only needs to be in the light sleep state and send SSB or CSI-RS with an 80 ms period. The base station only needs to trigger the transmission / reception of reference signals / channels in the lightly dormant state according to the second signal, so as to achieve energy saving of the base station while meeting the service requirements of the terminal. Optionally, the method of the embodiment of the present application further includes:
[0461] Sending a second response signal, where the second response signal is a response signal to the target signal, and the target signal includes the second signal, or includes the first signal and the second signal.
[0462] In the embodiment of the present application, the base station can send a first response signal after receiving the first signal and send a second response signal after receiving the second signal, or can also send the above second response signal after receiving the first signal and the second signal.
[0463] Optionally, the second response signal carries at least one of the following:
[0464] Confirmation information for the target signal; this confirmation information can be an OOK / ASK / FSK / PSK signal, for example, an OOK / ASK / FSK / PSK signal based on OFDM;
[0465] Feedback information for the target signal; this feedback information can be an OOK / ASK / FSK / PSK signal, for example, an OOK / ASK / FSK / PSK signal based on OFDM;
[0466] A second reference signal or a second channel; this second reference signal is a reference signal for subsequent determination of whether the terminal wakes up the dormant cell or a reference signal for providing a specific function for the terminal. For example, this specific function can be functions such as synchronization, measurement, or positioning. The reference signal can be an SSB, CSI-RS, TRS, random access preamble, etc. The second channel includes a downlink control channel and / or an uplink control channel.
[0467] Cell information of the cell sending the second response signal. Such as cell identification information.
[0468] Optionally, the second response signal can be sent by the target cell that receives the second signal.
[0469] For the feedback information or confirmation information where the second response signal is the second signal, in order to prevent the base station from being awakened by the terminals of each second signal, or being triggered to transmit and / or receive signals, or being triggered to switch to the second cell state, which may affect the energy saving gain of the base station. After detecting the second signal, the base station can determine whether to be awakened according to the internal implementation algorithm, or whether to be awakened is explicitly indicated by the second signal, or being triggered to transmit / receive signals, or being triggered to switch to the second cell state for confirmation or feedback, further instructing the terminal whether to awaken the cell, or whether to trigger the transmission / reception of signals, or whether to trigger the switch to the second cell state, or whether the second signal is received. On the one hand, it reduces the unconditional awakening of the base station, and on the other hand, it responds to the second signal sent by the terminal, so that both parties have the same understanding.
[0470] For the second response signal being the second reference signal and / or the second channel, for example: after the base station detects the second signal, it sends the second reference signal, such as: PSS, SSS, TRS, SSB, etc., and receives channels such as PRACH, PDCCH where Paging is located, which can be used for at least one of the following by the terminal: subsequent synchronization, RRM measurement, cell access, random access, and paging. The terminal receives / sends the second reference signal and / or the second channel within a specific time period after receiving the second response signal. After the terminal receives the response signal, the target cell provides services 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 the sleep state instead of always being in the service state, thus reducing the energy consumption on the network side.
[0471] Optionally, the method of the embodiment of the present application further includes:

[0508] It should be noted that the fourth moment, the fifth moment, and the sixth moment in the embodiment of the present application may be the same or different from each other.
[0509] The process of waking up or triggering the base station service by OOK / ASK / FSK / PSK signals will be described below in conjunction with Embodiments 2 to 5.
[0510] Embodiment 2: The base station is woken up after receiving the first signal.
[0511] As Figure 14 shown, this process includes:
[0512] Step 1: The terminal sends a first signal for the surrounding dormant cells / base stations (such as pico base stations) to discover the terminal. Among them, the first signal is an OOK / ASK / FSK / PSK signal based on OFDM. The first signal can be sent through a dedicated transmitter for the first signal 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 transmission location can be determined by one or several methods such as being configured by a neighboring cell higher layer signaling, being configured by a core network signaling, being sent by a broadcast signaling, or being defined by a protocol.
[0513] Step 2: The base station performs a first signal detection to obtain the information carried by the first signal, including: signal information and / or the 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 will not be awakened. Here, the first signal can carry M bits of information, where M is greater than or equal to 1, and the carried information includes at least one of the following:
[0514] Information related to the amplitude / phase / power / energy, etc. of the signal;
[0515] Indication information for waking up the cell.
[0516] In this embodiment, the first signal can be received by a dedicated receiver based on the first signal or by an NR receiver.
[0517] Illustrative example:
[0518] Suppose the first signal is an OFDM-based OOK signal. When the base station detects the first signal, it obtains one of the information related to the amplitude / phase / power / energy, etc., such as: obtaining the power value of the signal as P, or obtaining the amplitude value of the signal as A, or obtaining the energy value of the signal as E, or obtaining the phase information of the signal as θ.
[0519] Suppose the first signal is an OFDM-based OOK signal, and this signal carries N bits of indication information through modulation, etc., where N is greater than or equal to 1, for indicating the target cell to be awakened.
[0520] Specifically, the specific condition can be: the amplitude / phase / power / energy, etc. of the signal meets a specific threshold or a specific value or a specific value range.
[0521] For example, suppose 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 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.
[0522] Suppose the specific condition is greater than the amplitude threshold A0. If the base station detects that the amplitude value A of the first signal is greater than the amplitude threshold A0, 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.
[0523] Suppose the specific condition is greater than the energy threshold E0. If the base station detects that the energy value E of the first signal is greater than the energy threshold E0, 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.
[0524] Assume that the specific condition is that the phase value is within the 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 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. For example, when the terminal sends the first signal, different phase modulations can be performed on base stations in different directions. {0, π} is a cell in one direction, and {π, 2π} is a cell in one direction. The base station performs coherent demodulation on the received signal to obtain the value range where the phase of the first signal is located.
[0525] Assume that the specific condition is that the indication information carried by the first signal is a specific value. For example, 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.
[0526] When the base station determines that the current terminal falls within the service range of the base station, the sleeping cell is awakened and sends an SSB signal, or a CSI-RS or a reference signal for positioning to provide regular services for the terminal; otherwise, the sleeping cell will not be awakened.
[0527] Step 3: If the cell is awakened, perform at least one of the following:
[0528] Restore the service state;
[0529] Enter the light sleep state;
[0530] Send SSB / SIB1.
[0531] The terminal synchronizes to the SSB sent by the awakened cell, performs cell search, random access, or sends a scheduling request, etc.
[0532] Embodiment 3: After receiving the first signal, the base station is triggered to send / receive the first object;
[0533] As Figure 15 shown, the process includes:
[0534] Step 1: The terminal sends a first signal for surrounding sleeping cells / base stations (such as: Pico) to discover the terminal. The first signal is an OFDM-based OOK / ASK / FSK / PSK signal. The first signal can be sent through a dedicated transmitter for the first signal 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 transmission location can be determined by one or several methods such as neighbor cell high-layer signaling configuration, core network signaling configuration, broadcast signaling, or protocol definition.
[0535] Step 2: The base station performs a first signal detection to obtain the information carried by the first signal, including: signal information and / or the 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 will not send a specific reference signal. Here, the first signal can carry M bits of information, where M is greater than or equal to 1, and the carried information includes at least one of the following:
[0536] The signal information carried by the first signal can be information related to the amplitude / phase / power / energy, etc. of the signal.
[0537] The indication information carried by the first signal is used to trigger the cell to receive and / or send signals.
[0538] In this embodiment, the first signal can be received by a dedicated receiver based on the first signal or by an NR receiver.
[0539] Illustrative example:
[0540] Suppose the first signal is an OFDM-based OOK signal. When the base station detects the first signal, it obtains one of the relevant information such as its amplitude / phase / power / energy, etc. For example: 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.
[0541] Specifically, the specific condition can be: the amplitude / phase / power / energy, etc. of the signal meets a specific threshold or a specific value or a specific value range.
[0542] Illustrative example:
[0543] Suppose 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 is determined that the current terminal requires the base station side to send / receive a specific reference signal; otherwise, the base station determines that the current terminal does not require sending / receiving a specific reference signal.
[0544] Suppose the specific condition is greater than the amplitude threshold A0. If the base station detects that the amplitude value A of the first signal is greater than the amplitude threshold A0, it is determined that the current terminal requires the base station side to send / receive a specific reference signal; otherwise, the base station determines that the current terminal does not require sending / receiving a specific reference signal.
[0545] Suppose the specific condition is greater than the energy threshold E0. If the base station detects that the energy value E of the first signal is greater than the energy threshold E0, it is determined that the current terminal requires the base station side to send / receive a specific reference signal; otherwise, the base station determines that the current terminal does not require sending / receiving a specific reference signal.
[0546] Assume 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 requires the base station 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.
[0547] For example, when the base station determines that the current terminal requires the base station to send / receive a specific reference signal, the sleeping cell sends a specific reference signal according to the protocol limitation or according to the indication information carried in the first signal, such as: SSB signal, TRS signal, CSI-RS signal, positioning reference signal PRS / SRS, etc.; otherwise, the sleeping 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 several signals defined by the protocol. For example, when the protocol specifies that the base station receives the first signal and meets the specific condition, it sends the SSB signal. The SSB signal is sent at a default period of 20 ms. The same applies to other reference signals.
[0548] Assume that the specific condition is that the indication information carried in the first signal is the indication information of the specific reference signal, that is, different values correspond to different reference signals. For example, N bits respectively correspond to M kinds of reference signals, and the base station triggers the sending and / or receiving of the corresponding specific reference signal according to the indication information.
[0549] For example, when the base station receives the first signal and the first signal carries the indication information of the specific reference signal, such as: N1 bits in N bits are used to indicate the 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. Further, when the base station determines that the current terminal requires the base station to send / receive a specific reference signal, the sleeping cell can configure a certain parameter in multiple configurations of the specific reference signal according to the indication information. For example: when the base station receives the indication information carried in the first signal indicating the sending of the positioning reference signal PRS and indicating a certain parameter configuration in the pre-configured parameter configuration, the base station sends the specific reference signal according to the specific parameter configuration.
[0550] Step 3: In the case where the cell is triggered to send a specific reference signal, perform at least one of the following:
[0551] Send SSB / SIB1
[0552] Send the downlink synchronization signal TRS
[0553] Send the positioning reference signal.
[0554] The terminal synchronizes, searches for the cell, performs random access, or sends a scheduling request, etc. based on the specific reference signal sent by the sleeping cell.
[0555] Embodiment 4: The base station is fully or partially awakened after sending the first response signal;
[0556] As Figure 16 shown, it includes:
[0557] Step 1: The terminal sends a first signal for the surrounding sleeping cells / base stations (such as: Pico) to discover the terminal. Among them, the first signal is an OFDM-based OOK / ASK / FSK / PSK signal. The first signal can be sent through a dedicated transmitter for the first signal or through an NR transmitter.
[0558] Step 2: The base station performs first signal detection to obtain the information carried by the first signal, including: signal information and / or carried indication information. If the first signal meets specific conditions (i.e., the first condition), it sends a first response signal to the terminal. Or, if the first signal does not meet the specific conditions, the cell does not send a first response signal. Here, the first signal can carry M bits of information, M is greater than or equal to 1, and the carried information includes at least one of the following:
[0559] Information related to the amplitude / phase / power / energy, etc. of the signal.
[0560] Indication information for triggering the cell to receive and / or send signals.
[0561] In this embodiment, the first signal can be received through a dedicated receiver based on the first signal or through an NR receiver.
[0562] Illustrative example:
[0563] Suppose the first signal is an OFDM-based OOK signal. When the base station detects the first signal, it obtains one of the information related to its amplitude / phase / power / energy, etc. For example: 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.
[0564] Taking the first signal as an OOK-1 signal as an example, the first signal can carry 1 bit of information for the sleeping cell to discover the terminal. The first signal can be sent N times at a specific time point or time period, N is greater than or equal to 1, and the specific sending location can be determined by one or several methods such as neighbor cell high-layer signaling configuration, core network signaling configuration, broadcast signaling sending, or protocol limitation.
[0565] Step 3: The base station sends a first response signal to the first signal. Here, the first response signal can be sent when the base station detects that the signal information of the first signal meets specific conditions. Specifically, the specific conditions can be: the amplitude / phase / power / energy, etc. of the signal meet a specific threshold or a specific value or a specific value range. The first response signal can also be that the base station sends the first response signal as long as it detects the first signal.
[0566] For specific specific conditions, reference can be made to Embodiment 2 and Embodiment 3.
[0567] The first response signal can carry at least one of the following:
[0568] The first item: Carry the confirmation information of the cell 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.
[0569] For example: The base station detects that within a certain period of time, the amplitude of the signal is higher than a specific threshold value, then it determines that a terminal has entered the service range of this cell. Therefore, the base station determines that it needs to be awakened, and then sends a first response signal to the terminal. For example: Carry a 1-bit OOK signal. After the terminal sends the first signal, it performs the reception detection of the first response signal within a specific time interval.
[0570] The second item: Carry the cell information of this cell, etc. For example: The cell information can be a predefined sequence or signal pattern, etc. Here, the first response signal can be an OFDM-based OOK / ASK / FSK / PSK signal. The predefined sequence or signal pattern corresponding to the cell information can be information pre-configured by the terminal, or limited by neighboring cells or the core network or protocols.
[0571] For example: The base station detects that within a certain period of time, the amplitude of the signal is higher than a specific threshold value, then it determines that a terminal has entered the service range of this cell. Therefore, the base station determines that it needs to be awakened, and then sends a first response signal to the terminal. This first response signal includes M-bit information, corresponding to the cell information pre-configured or pre-defined by the cell. After the terminal sends the first signal, it performs the reception detection of the first response signal within a specific time interval.
[0572] The third item: The cell sends feedback information on the indication information carried by the first signal. For example: The feedback information carried by the first signal.
[0573] For example: If the N-bit information of the first signal carries the indication information of M1 specific reference signals and / or M2 specific parameter configurations, then when the base station detects the first signal and meets specific conditions, it sends the feedback information corresponding to the indication information to the terminal, that is, the confirmation information of the indication information of the m1th specific reference signal, and / or the confirmation information of the indication information of the m2th parameter configuration.
[0574] Item 4: A reference signal for the terminal to perform time-frequency synchronization, such as: SSB signal.
[0575] For example: If the base station detects that the amplitude of the signal is higher than a specific threshold within a certain period of time, it is determined that a terminal has entered the service range of this cell. Therefore, the base station determines that it needs to be woken up and sends a response signal to the terminal. The first response signal is a specific reference signal, such as: the SSB signal for the terminal time-frequency synchronization.
[0576] Step 4: After the specific cell sends the first response signal, perform at least one of the following:
[0577] Restore the service state, that is, be fully woken up;
[0578] Enter the light sleep state;
[0579] Send SSB / SIB1;
[0580] Send the downlink synchronization signal TRS;
[0581] Send the positioning reference signal.
[0582] Step 5: After the terminal receives the first response signal, receive the SSB or the specific reference signal, and perform synchronization, cell search, random access, or send a scheduling request, etc.
[0583] Embodiment 5: The base station sends a second signal to wake up or trigger the transmission / reception of the second object;
[0584] Such as Figure 17 shown, this process includes:
[0585] Step 1: The terminal sends a first signal for the surrounding sleeping cells / base stations (such as: Pico) to discover the terminal. Among them, the first signal is an OFDM-based OOK / ASK / FSK / PSK signal. The first signal can be sent through a dedicated transmitter for the first signal or through an NR transmitter.
[0586] Step 2: The base station performs the first signal detection and obtains the 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:
[0587] The signal information carried by the first signal can be information related to the amplitude / phase / power / energy, etc. of the signal.
[0588] The indication information carried by the first signal is used to trigger the cell to receive and / or send signals.
[0589] In this embodiment, the first signal can be received by a dedicated receiver based on the first signal or by an NR receiver.
[0590] For example:
[0591] Suppose the first signal is an OFDM-based OOK signal. When the base station detects the first signal, it obtains one of the relevant information such as amplitude / phase / power / energy, etc. For example: 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.
[0592] Step 3: The base station sends a first response signal for the first signal. Here, the first response signal can be sent when the signal information of the first signal detected by the base station meets specific conditions. Specifically, the specific conditions can be: the amplitude / phase / power / energy, etc. of the signal meet a specific threshold or a specific value or a specific value range. The first response signal can also be that when the base station detects the first signal, it will send the first response signal.
[0593] For specific specific conditions, reference can be made to Embodiment 2 and Embodiment 3.
[0594] The first response signal can be at least one of the following situations:
[0595] The first item: Carrying the confirmation information of the cell receiving the first signal. For example: N-bit ACK information, used to indicate that the base station has detected the first signal.
[0596] The second item: Carrying the cell information of this cell, etc. For example: The cell information can be a predefined sequence or signal pattern, etc.
[0597] The third item: The feedback information of the cell on the indication information carried by the first signal. For example: The feedback information carried by the first signal.
[0598] The fourth item: The specific reference signal (i.e., the first reference signal) sent / received by the cell.
[0599] For example:
[0600] If the first signal is used to wake up a dormant cell, the base station sends a first response signal to confirm that it has been woken up.
[0601] If the first signal carries the 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.
[0602] If the first signal carries the indication information for sending / receiving the triggered first target reference signal, the base station makes a feedback according to the indication information.
[0603] If the base station sends a first response signal to the terminal after receiving the first signal, the first response signal includes acknowledgment information and / or a specific reference signal, such as at least one of an SSB signal, an SIB signal, etc.
[0604] Step 4: After the terminal receives the first response signal, it receives a specific reference signal (the first reference signal), such as an SSB, for 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 transmission / reception of a 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.
[0605] For example:
[0606] When the second signal is an OFDM-based OOK / ASK / FSK / PSK signal, the generation method and the carried information can refer to the first signal in the previous embodiments.
[0607] 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 the exclusive signaling for cell wake-up.
[0608] The second signal can carry at least one of the following information:
[0609] Cell wake-up indication information, that is, whether to wake up a dormant cell;
[0610] Cell identification related information, that is, the related cell information used to indicate the transmission and / or reception of the wake-up or trigger signal / channel;
[0611] Specific reference signal (i.e., the second target reference signal) transmission and / or reception indication information, that is, the specific reference signal used to indicate the cell transmission / reception;
[0612] Function trigger indication information, that is, used to indicate the cell to turn on or off a specific function, such as measurement, synchronization, positioning, energy saving, access, specific service transmission, etc.;
[0613] Terminal specific identification, that is, 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;
[0614] Identifiers related to terminal demand information, that is, used to indicate the current service demand of the terminal, such as access, measurement, synchronization, positioning, energy saving, specific service transmission requirements, etc.; or, used to indicate the current service demand of the terminal, such as eMBB service, XR service, URLLC service, mMTC service, AIoT service, etc.
[0615] Cell status indication information, that is, used to indicate that the cell switches between at least one state or switches to the second state.
[0616] Step 5: After a specific cell receives a second signal for sending / receiving an indication for waking up or triggering the sending of a specific reference signal, perform at least one of the following:
[0617] Resume the service state, that is, wake up;
[0618] Enter the light sleep state;
[0619] Send SSB / SIB1;
[0620] Send the downlink synchronization signal TRS;
[0621] Send the positioning reference signal.
[0622] That is, wake up or be partially woken up after receiving the second signal, or send / receive a specific reference signal, SSB, measurement CSI-RS, or synchronization signal, etc.
[0623] Here, partial wake-up means that the base station only sends and / or receives some reference signals, or switches to parameter configuration in the energy-saving state, etc. For details, please refer to Embodiment 3.
[0624] In the embodiments of the present application, the above OOK / ASK / FSK / PSK signal is a low-power signal different from the OFDM signal. The processing method of this low-power signal is different from the processing method of the existing OFDM signal. A cell in the sleep state or the energy-saving state can process this low-power signal, so that the terminal can communicate with the sleeping cell or the cell in the energy-saving state without synchronization through this low-power signal, and further achieve the purpose of waking up the sleeping cell or triggering the sleeping cell to wake up to provide services.
