Description

Signal transmission method and device

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on December 7, 2023, with application number 202311675525.0 and application name “Signal Transmission Method and Device,” the entire contents of which are incorporated by reference into this disclosure.

[0348] In some embodiments, the above-mentioned first reference signal includes at least one of the following: primary synchronization signal (PSS), secondary synchronization signal (SSS), synchronization signal / physical broadcast channel signal block (Synchronization Signal Block, SSB), tracking reference signal (CSI Reference Signal for Tracking, TRS), positioning reference signal (Positioning Reference Signal, PRS), phase tracking reference signal (Phase-tracking reference signal, PT-RS), random access preamble code, sounding reference signal (SRS), demodulation reference signal (DMRS), CSI reference signal (CSI Reference Signal, CSI-RS).

[0349] In some embodiments, the first channel includes at least one of the following: physical uplink control channel (PUCCH), physical downlink control channel (PDCCH), physical broadcast channel (PBCH), physical random access channel (PRACH), physical sidelink shared channel (PSSCH), physical downlink shared channel (PDSCH), and physical uplink shared channel (PUSCH).

[0350] The first object is defined by the protocol or pre-configured by high-layer signaling.

[0351] In the disclosed embodiment, an uplink signal is sent, the uplink signal carrying at least one of discovery information and trigger information; the discovery information is used to discover a terminal; the trigger information is used to at least one of the following: wake up a target cell; trigger the target cell to send and / or receive a first object, the first object including at least one of a first reference signal and a first channel; trigger the target cell to switch to a target cell state. Thus, the above-mentioned discovery information and / or trigger information can be used to wake up a dormant cell or trigger a dormant cell to wake up and provide services.

[0352] In some embodiments, the uplink signal includes a modulation signal, and the modulation signal includes at least one of an on-off keying (OOK) signal; an amplitude shift keying (ASK) signal; a frequency shift keying (FSK) signal; and a phase shift keying (PSK) signal.

[0353] In some embodiments, the above-mentioned terminal includes a terminal to be served, which may be a dedicated terminal that only sends / receives OFDM-based OOK / ASK / FSK / PSK signals, or a terminal that simultaneously sends / receives OFDM-based OOK / ASK / FSK / PSK signals and sends / receives NR signals. Here, the OOK / ASK / FSK / PSK uplink signal sent by the terminal may be based on a multi-carrier waveform, such as a cyclic prefix (CP)-OFDM, or may be based on a single-carrier waveform, such as a discrete Fourier transform-spread (DFT-S)-OFDM.

[0354] The above-mentioned OOK / ASK / FSK / PSK signal is a low-power signal different from the OFDM signal. The processing method of the low-power signal is different from the processing method of the OFDM signal in the relevant technology in some embodiments. The cell in the sleep state or energy-saving state can process the low-power signal, so that the terminal can communicate with the sleep cell or the cell in the energy-saving state without synchronization through the low-power signal, thereby achieving the purpose of waking up the sleep cell or triggering the sleep cell to wake up and provide services.

[0355] In some embodiments, the modulated signal is an Orthogonal Frequency Division Multiplexing (OFDM) based signal.

[0356] When the above-mentioned modulated signal is an OFDM-based OOK / ASK / FSK / PSK signal, the existing NR transceiver architecture can be utilized to further avoid adding new transceivers, thereby simplifying the complexity of the transceiver. Signal detection based on OOK / ASK / FSK / PSK modulation can greatly reduce the power consumption of the receiving end, thereby achieving energy saving, because it does not require the inverse fast Fourier transform (IFFT) operation to perform envelope, filtering or phase detection.

[0357] In some embodiments, the uplink signal includes an OFDM-based reference signal or channel.

[0358] The OFDM-based reference signal or channel is an OFDM-based reference signal or channel in NR, such as a reference signal that is at least one of PSS, SSS, SSB, TRS, PRS, PT-RS, random access preamble, SRS, DMRS, and CSI-RS, and an OFDM-based channel in NR that is at least one of PUCCH, PDCCH, PBCH, PRACH, PSSCH, PDSCH, and PUSCH.

[0359] In some embodiments, the discovery information includes at least one of amplitude, frequency, carrier, bandwidth, phase, power, and energy of a signal used for signal detection.

[0360] The discovery information is used by cells or base stations (such as Pico) around the terminal to discover the terminal.

[0361] In some embodiments, the trigger information includes at least one of the following:

[0362] first indication information, where the first indication information is indication information for waking up the target cell;

[0363] second indication information, where the second indication information is indication information for triggering the target cell to receive and / or send a first object, where the first object includes: at least one of a first reference signal and a first channel;

[0364] third indication information, where the third indication information is indication information for triggering the target cell to switch to the target cell state;

[0365] The fourth indication information is used to indicate the identification information of the target cell; for example, when the trigger information only includes the fourth indication information, the target cell indicated by the fourth indication information is determined to be a target cell that needs to be awakened, a cell that needs to send and / or receive the first object, and / or a cell that needs to be switched to the target cell state through protocol agreement or base station pre-configuration. After the network-side device receives the fourth indication information, if the cell's identity is consistent with the identity indicated by the fourth indication information, it enters the awakened state, sends and / or receives the first object, and / or switches to the target cell state.

[0366] Fifth indication information, where the fifth indication information is used to trigger the target cell to enable and / or disable a specific function;

[0367] Sixth indication information, where the sixth indication information is used to indicate a specific identifier of the terminal;

[0368] The seventh indication information is used to indicate the requirement information of the terminal.

[0369] In some embodiments, at least one indication information in the trigger information is indicated in an explicit or implicit manner.

[0370] As an implementation manner, the implicit indication manner may be a protocol agreement or a base station pre-configuration indication of at least one of the above indication information or an implicit indication of at least one of the above indication information through a specific sequence of an uplink signal.

[0371] Exemplarily, the uplink signal includes a discovery signal carrying discovery information. The discovery signal may carry at least one of the above-mentioned indication information, for example, the first indication information and / or the second indication information, through protocol agreement or base station pre-configuration. For example, different sequences of the discovery signal may implicitly indicate different indication information through protocol agreement or base station pre-configuration.

[0372] As an implementation method, the above-mentioned uplink signal includes a trigger signal carrying trigger information. The explicit indication method can be indicated through the information field of the trigger signal. For example, there is an exclusive information field corresponding to each indication information in the trigger signal. At least one of the above-mentioned indication information can also be jointly indicated through an information field. In addition to being the information field in the trigger signal, the information field can also be a sequence of a specific length.

[0373] For example, the protocol agreement or base station pre-configuration implicitly indicates at least one item of the above indication information through discovery information, or implicitly indicates at least one item of the above indication information through a specific sequence of trigger signals.

[0374] In some embodiments, the trigger information includes N bits of information, where N is an integer greater than or equal to 0;

[0375] The N bits of trigger information are used to indicate the M indication information in the trigger information, and the i-th indication information in the M indication information corresponds to the K bits in the N bits. i bits and different indication information corresponds to different bits in the N bits, M is an integer greater than or equal to 1, and M is less than or equal to N, K i Less than or equal to N, and K i Greater than or equal to 0; and / or, the value or pattern corresponding to the N1 bit in the N-bit information in the trigger information is used to indicate at least one indication information in the trigger information, wherein N1 is an integer greater than or equal to 1, and N1 is less than or equal to N.

[0376] For example, M=N, and K i =1, N indication information is indicated by N bits of information, and each indication information corresponds to one bit, that is, the above indication information is indicated by bit mapping, that is, each indication information is indicated by one bit alone.

[0377] For another example, when M and N are different, N bits indicate M indication information, and the i-th indication information in the M indication information corresponds to the Kth indication information in the N bits. ibits, 1≤i≤M, and K1+K2+…+≤N. For example, if M is 3 and N is 8, the first indication information corresponds to the first and second bits, the second indication information corresponds to the third and fourth bits, and the third indication information corresponds to the fifth and sixth bits. For another example, the first indication information corresponds to the first bit, the second indication information corresponds to the second and third bits, and the third indication information corresponds to the fourth to eighth bits.

[0378] For another example, the protocol stipulates that when the terminal does not send a trigger signal, the trigger information is default, that is, N=0.

[0379] In some embodiments, the trigger information includes N bits of information, including: an information function indication field and an indication information field, wherein the information function indication field can indicate the specific content of the indication information field through bit mapping, value or specific pattern.

[0380] For example, the information function indication field has 3 bits of information, corresponding to the first indication information, the second indication information, and the third indication information. Assuming that the second bit information corresponds to "1", the subsequent indication information field is the second indication information.

[0381] For another example: the information function indication field has 2 bits of information, its value "01" corresponds to the first indication information, "10" corresponds to the second indication information, and "11" corresponds to the third indication information. Assuming that the value of the information function indication field is "10", the subsequent indication information field is the second indication information.

[0382] For another example, the information function indication field has an N-bit sequence of M patterns, and different patterns correspond to different indication information. According to the bit sequence pattern of the information function indication field, it is possible to know which indication information the subsequent indication information field specifically indicates.

[0383] In some embodiments, the first indication information includes at least one of indication information of whether to wake up the target cell and indication information of the woken target cell;

[0384] And / or, the first indication information includes A1 bit information, and the value and / or sequence corresponding to the A1 bit information is used to indicate whether to wake up the target cell and / or indicate the woken target cell, and A1 is an integer greater than or equal to 0.

[0385] In the embodiment of the present disclosure, the uplink signal may include first indication information corresponding to multiple target cells, and the first indication information corresponding to each target cell includes A1 bit information. When A1 is equal to 1, a wake-up indication is given to at least one target cell or target cell group through bit mapping, that is, each bit corresponds to a cell or a cell group. For example, when the value is "1", the corresponding cell or cell group is woken up; when the value is "0", the corresponding cell or cell group is not woken up. Among them, the cell or cell group corresponding to the bit mapping is obtained through pre-configuration.

[0386] For example, A1 is an integer greater than 1, and the A1 bit information corresponding to the first indication information is an A1 bit sequence of a specific style. The terminal sends the A1 bit sequence at a pre-configured or protocol-agreed resource location. The specific style of the A1 bit sequence can be pre-stored or pre-configured. After the base station receives the A1 bit sequence of the specific style, if its specific style is consistent with the pre-stored or pre-configured pattern sequence, it is considered that the indicated cell is awakened; otherwise, the indicated cell is not awakened.

[0387] For another example, when the value corresponding to the A1 bit information corresponding to the first indication information is the first value, it indicates that the cell is awakened; when the value corresponding to the A1 bit information corresponding to the first indication information is the first value, it indicates that the cell is not awakened.

[0388] For another example, the target cell wake-up indication is performed based on whether the first indication information is contained, that is: if the first indication information is sent, the target cell or cell group is woken up, and A1 is greater than or equal to 1; if the first indication information is not sent, the target cell or cell group is not woken up, and A1 is equal to 0.

[0389] In some embodiments, the second indication information includes at least one of indication information of whether to send and / or receive the first object, and indication information of sending and / or receiving the first object;

[0390] And / or, the second indication information includes A2 bits, where A2 is an integer greater than or equal to 0; the second indication information indicates whether to send and / or receive the first object, or at least one of sending and / or receiving the first object, through A3 bits in the A2 bits, or indicates whether to send and / or receive the first object, or at least one of sending and / or receiving the first object, through the sequence and / or value corresponding to the A2 bits; A3 is less than or equal to A2, and A3 is an integer greater than or equal to 0;

[0391] And / or, when A3 is greater than 1, the A3 bits indicate, by bit mapping, whether to send and / or receive the first object, or at least one of sending and / or receiving the first object. For example, each bit in A3 bits corresponds to a different first object.

[0392] In the embodiment of the present disclosure, A3 corresponding to different indication information in the second indication information is the same or different.

[0393] For example, A2=5, the first bit of the 5 bits indicates the first reference signal, and the second bit of the 5 bits indicates the second reference signal. When the value corresponding to the first bit is 1, it indicates that the first reference signal is sent and / or received. When the value corresponding to the first bit is 0, it indicates that the first reference signal is not sent and / or received. When the value corresponding to the second bit is 1, it indicates that the second reference signal is sent and / or received. When the value corresponding to the second bit is 0, it indicates that the second reference signal is not sent and / or received.

[0394] For another example, if A2=5, the first and second bits of the five bits indicate a first reference signal, and the third to fifth bits of the five bits indicate a second reference signal. The values ​​or patterns corresponding to the first and second bits are used to indicate the corresponding parameter configuration of the first reference signal, e.g., "00" indicates transmission and / or reception according to the first parameter configuration of the first reference signal, "01" indicates transmission and / or reception according to the second parameter configuration of the first reference signal, etc. The values ​​or patterns corresponding to the third to fifth bits are used to indicate the corresponding parameter configuration of the second reference signal, e.g., "001" indicates transmission and / or reception according to the first parameter configuration of the second reference signal, "010" indicates transmission and / or reception according to the second parameter configuration of the second reference signal, etc.

[0395] For another example, different sequences or different values ​​corresponding to A2 bits are used to indicate different first objects. For example, when A2 bits correspond to a value of 1 or sequence 1, it is used to indicate the transmission and / or reception of a first reference signal and a second reference signal; and when A2 bits correspond to a value of 2 or sequence 2, it is used to indicate the transmission and / or reception of a third reference signal and a fourth reference signal.

[0396] For another example, whether to send and / or receive the first object is indicated by whether the second indication information is contained, that is: sending the second indication information indicates sending and / or receiving the first object, and A2 is greater than or equal to 1; not sending the second indication information indicates not sending and / or not receiving the first object, and A2 is equal to 0.

[0397] In some embodiments, the third indication information includes at least one of indication information indicating whether the target cell is switched between at least one cell state, and indication information indicating whether to switch or maintain to the target cell state;

[0398] And / or, the third indication information includes A4 bits, where A4 is an integer greater than or equal to 0; the third indication information indicates, through A5 bits among the A4 bits, whether to switch between at least one cell state, switch to, or maintain at least one of the target cell states, or, through a sequence and / or value corresponding to the A4 bits, indicates whether to switch between at least one cell state, switch to, or maintain at least one of the target cell states; A5 is less than or equal to A4, and A5 is an integer greater than or equal to 0;

[0399] And / or, when A5 is greater than 1, the A5 bits indicate, by bit mapping, whether to switch between at least one cell state, switch to, or maintain at least one of the target cell states. For example, each bit in the A5 bits corresponds to a different target cell state.

[0400] In the embodiment of the present disclosure, A5 corresponding to different indication information in the third indication information is the same or different.

[0401] For example, A4=5, the first bit of the 5 bits indicates the first energy-saving state, and the second bit of the 5 bits indicates the second energy-saving state. When the value corresponding to the first bit is 1, it indicates switching to the first energy-saving state. When the value corresponding to the first bit is 0, it indicates not switching to the first energy-saving state. When the value corresponding to the second bit is 1, it indicates switching to the second energy-saving state. When the value corresponding to the second bit is 0, it indicates not switching to the second energy-saving state.

[0402] For another example, different sequences or values ​​corresponding to the A4 bits are used to indicate different target cell states. For example, when the A4 bits correspond to a value of 1 or sequence 1, it is used to indicate the first target cell state, and when the A4 bits correspond to a value of 2 or sequence 2, it is used to indicate the second target cell state.

[0403] For another example, whether to switch between at least one state is indicated by whether the third indication information is contained, that is: sending the third indication information indicates switching between at least one state, and A4 is greater than or equal to 1; not sending the third indication information indicates switching between at least one state, and A4 is equal to 0.

[0404] In some embodiments, the third indication information includes a first information field and a second information field, the first information field is used to indicate the target cell state, and the second information field is used to indicate the reference signal and / or channel corresponding to the target cell state.

[0405] For example, the first information field has 3 bits of information, corresponding to cell state 1, cell state 2 and cell state 3 respectively. Assuming that the second bit information is 1, the second information field is used to indicate the reference signal and / or channel corresponding to cell state 2.

[0406] For another example, the first information field has 2 bits of information, whose value is "01" corresponding to cell state 1, "10" corresponding to cell state 2, and "11" corresponding to cell state 3. Assuming that the value of the first information field is "10", the second information field is used to indicate the reference signal and / or channel corresponding to cell state 2.

[0407] For another example, the first information field has M patterns of N-bit sequences, and different patterns correspond to different cell states. Based on the bit sequence pattern of the first information field, the cell state corresponding to the subsequent second information field can be known.

[0408] In the embodiment of the present disclosure, specific reference signals and / or channels in different cell states can be configured through at least one of high-layer signaling, core network signaling, terminal pre-storage, neighboring cell signaling notification, etc.

[0409] In some embodiments, the fourth indication information includes at least one of an index in a frequency list of a cell, an index in a cell list, a cell identifier, a cell ID, and a bit map of at least one cell.

[0410] For example, modulation patterns of different OOK / ASK / FSK / PSK modulation signals correspond to cell IDs or index values ​​of cell lists in different cells or cell groups.

[0411] For another example, the fourth indication information is used in conjunction with other indication information. For example, the trigger information contains N bits of information, which can be divided into M information groups, each of which corresponds to a target cell or target cell group. Each information group includes Ki bits of information, which can correspond to at least one indication information. For example, Ki bits can be used to indicate the second indication information and the third indication information, and Ki bits can also be used to indicate the first reference signal and the first channel. The indication method can be used for separate indications or for combined indications.

[0413] And / or, the fifth indication information includes A6 bits, where A6 is an integer greater than or equal to 0; the fifth indication information indicates whether to turn on and / or turn off a specific function, or at least one item of the indication information of turning on and / or turning off at least one specific function, through A7 of the A6 bits, or indicates whether to turn on and / or turn off a specific function, or at least one item of the indication information of turning on and / or turning off at least one specific function, through a sequence and / or value corresponding to the A6 bits, where A7 is less than or equal to A6, and A7 is an integer greater than or equal to 0;

[0414] And / or, when A7 is greater than 1, the A7 bits indicate, through bit mapping, whether to enable and / or disable a specific function, or at least one of the indication information of enabling and / or disabling at least one specific function. For example, each bit in A7 corresponds to a different specific function;

[0415] The above-mentioned specific functions include at least one of the following: access function, measurement function, synchronization function, positioning function, energy saving function, and specific service transmission function, such as sending and / or receiving a specific reference signal (set) / transmission channel (set) under at least one specific parameter configuration;

[0416] In the embodiment of the present disclosure, A7 corresponding to different indication information in the fifth indication information is the same or different.

[0417] For example, A6=5, the first specific function is indicated by the first bit of the 5 bits, and the second specific function is indicated by the second bit of the 5 bits. When the value corresponding to the first bit is 1, it means that the first specific function is turned on.

When the value corresponding to the second bit is 1, it means that the second specific function is turned on. When the value corresponding to the second bit is 0, it means that the second specific function is turned off.

[0445] In the embodiments of the present disclosure, discovery information and bearer information may be carried by the same signal or by different signals:

[0446] As an optional implementation manner: the uplink signal includes a first uplink signal, and the first uplink signal carries discovery information and trigger information;

[0447] In this implementation, the first uplink signal is a modulated signal based on OOK / ASK / FSK / PSK. For example, the first uplink information is used to discover the terminal and wake up the target cell;

[0448] Alternatively, in some embodiments: the uplink signal includes a second uplink signal and a third uplink signal, the second uplink signal carries the discovery information, and the third uplink signal carries the trigger information;

[0449] In this implementation, the second uplink signal is a modulated signal based on OOK / ASK / FSK / PSK, and the third uplink signal is a modulated signal based on OOK / ASK / FSK / PSK, or a reference signal based on OFDM. For example, the second uplink signal is used to discover the terminal, and the third uplink signal is used to trigger the target cell to send and / or receive the first object;

[0450] Alternatively, as a third implementation manner: the uplink signal includes a fourth uplink signal and a fifth uplink signal, the fourth uplink signal is used to carry the discovery information and the first trigger information in the trigger information, and the fifth uplink signal is used to carry the second trigger information in the trigger information, wherein the first trigger information is the same as at least part of the information of the second trigger information, or the second trigger information is the trigger information in the trigger information other than the first trigger information in the trigger information;

[0451] In this implementation, the first trigger information and the second trigger information are complementary trigger information or at least partially overlapping trigger information. For example, the fourth uplink signal is used to discover the terminal and trigger the target cell to send and / or receive the first object, and the fifth uplink signal is used to wake up the target cell or trigger the target cell to switch to the target cell state. The fourth uplink signal is a modulated signal based on OOK / ASK / FSK / PSK, and the fifth uplink signal is a modulated signal based on OOK / ASK / FSK / PSK, or a reference signal based on OFDM.

[0452] Alternatively, as a fourth implementation method: the trigger signal includes a sixth uplink signal and a seventh uplink signal, the sixth uplink signal is used to carry the first discovery information in the discovery information and the third trigger information in the trigger information, and the seventh uplink signal is used to carry the second discovery information in the discovery information and the fourth trigger information in the trigger information, wherein the first discovery information is the same as or different from the second discovery information; and the third trigger information is at least partially the same as the fourth trigger information, or, the fourth trigger information is the trigger information in the trigger information other than the third trigger information.

[0453] In some embodiments, the first discovery information includes at least part of the discovery information, and the second discovery information includes at least part of the discovery information.

[0454] In this implementation, the third trigger information and the fourth trigger information are complementary trigger information or at least partially overlapping trigger information. For example, the fourth uplink signal is used to discover the terminal and trigger the target cell to send and / or receive the first object, and the fifth uplink signal is used to discover the terminal and wake up the target cell. The sixth uplink signal is a modulated signal based on OOK / ASK / FSK / PSK, and the seventh uplink signal is a modulated signal based on OOK / ASK / FSK / PSK.

[0455] In some embodiments, the method of the present disclosure further includes:

[0456] Acquiring resource-related information of the uplink signal, where the resource-related information is used to generate the uplink signal and / or to determine a sending resource location of the uplink signal;

[0457] The resource-related information is obtained based on at least one of the resource information stored in the terminal, the resource information configured by the neighboring cell high-level signaling, the resource information configured by the core network signaling, the resource information sent by the broadcast signaling, and the resource information defined by the protocol.

[0458] In some embodiments, the resource-related information of the uplink signal includes at least one of the following:

[0459] Information related to the generation of uplink signals;

[0460] Resource location information of uplink signals;

[0461] The generated relevant information includes at least one of the transmission frequency, the number of frequency domain units, the pattern occupied by the frequency domain units, the time domain reference point, the number of time domain units occupied, the number of segments of the uplink signal, the number of points of the inverse fast Fourier transform IFFT, the sequence length of the uplink signal, the sequence length of at least one indication information in the uplink signal, and the number of at least one indication information in the uplink signal;

[0462] The resource location information includes at least one of time domain resource location information, frequency domain resource location information, and space domain resource location information.

[0463] In some embodiments, the time domain resource location information includes at least one of the following: time domain location information of the uplink signal; association information with the time domain location of a specific signal / channel; duration of uplink signal transmission; effective time of uplink signal transmission; effective time interval of uplink signal transmission; uplink signal transmission pattern within a specific time period; number of times the uplink signal is transmitted; and cycle of uplink signal transmission.

[0464] In the disclosed embodiments, the time domain resources of the uplink signal may be periodic, semi-persistent, or transmitted in a certain pattern within a transmission time window, or associated with a specific signal or specific channel. The specific signal includes at least one of the PSS, SSS, SSB, SIB1, TRS, PRS, PT-RS, random access preamble, SRS, DMRS, and CSI-RS. The specific channel includes at least one of the PUCCH, PDCCH, PBCH, PRACH, PSSCH, PDSCH, and PUSCH.

[0465] For example, the time domain resource location of the uplink signal can be transmitted periodically or semi-continuously. The base station can detect the uplink signal continuously or based on a detection window, depending on the base station implementation. The detection window can also be periodic or based on a timer trigger. The transmission period of the uplink signal can be a default period, such as specified by the protocol, or consistent with the default period of a specific reference signal, such as the default period of 20ms for SSB.

[0466] When the uplink signal is semi-persistently transmitted, the terminal may start transmitting when it needs to wake up or trigger a specific cell to provide service for it. The transmission time of the uplink signal may be based on the system frame number (SFN).

[0467] For another example: the uplink signal is sent within a specific time window. The time window can be a time window for repeated transmission (as shown in Figure 5), or a time window for continuous transmission of the uplink signal (as shown in Figure 5), or it can be sent in a specific pattern within the time window (as shown in Figure 6). For another example: there is a correlation between the uplink signal and a specific reference signal. For example, there is a specific offset between the transmission position of the uplink signal and the position of the specific reference signal or a specific channel. Here, the specific offset can be a value greater than or equal to 0 (as shown in Figure 8), or it can be a value less than or equal to 0 (as shown in Figure 9).

[0468] In some embodiments, there is an association between the discovery information and the trigger information. For example, the sending period of the trigger information is S times or 1 / S of the sending period of the discovery information, where S is a positive integer. Alternatively, when the two information are carried by the same signal, the discovery information occupies M1 time slot symbols, and the trigger information occupies M2 time slot symbols. Alternatively, there is a specific timing relationship between the first sequence signal carrying the trigger information and the second sequence signal carrying the discovery information, such as a difference of M3 time units or M4 sequence lengths. Alternatively, there is a specific time offset between the first signal carrying the trigger information and the second signal carrying the discovery information, such as a difference of M5 time units. Here, the time unit can be a time slot, a symbol, a millisecond, or a second. The sequence length can be bit information or a bit information corresponding to a time unit.

[0469] In some embodiments, the frequency domain resource information of the uplink signal includes at least one of the following: the subcarrier where the uplink signal is located; the bandwidth part BWP or frequency point where the uplink signal is located, such as the exclusive frequency point or exclusive BWP where the uplink signal is located; the transmission pattern of the frequency domain where the uplink signal is located.

[0470] For example, a specific BWP corresponding to a specific carrier frequency can be used for uplink signal transmission. In this BWP, there are N subcarriers, and the uplink signal can occupy M of these subcarriers, where M is an integer less than or equal to N. The M subcarriers can be the M with the smallest sequence numbers among the N subcarriers, or the M with the largest sequence numbers, or M random subcarriers, or M subcarriers with a specific pattern. The specific pattern can be configured by the base station, pre-configured by the terminal, pre-stored by the terminal, obtained based on the terminal ID or cell ID or parameters related to the generated sequence, or generated based on a scrambling code or a pseudo-random sequence, among other methods.

[0471] In some embodiments, the spatial resource location information of the uplink signal includes beam-related information of the uplink signal, for example, omnidirectional antenna transmission and / or specific beam direction transmission.

[0472] For example, when an uplink signal carries discovery information, it can be sent via an omnidirectional antenna or in different beam directions using time division. When the terminal receives a response signal corresponding to the corresponding beam, it can determine the target cell.

[0473] For another example: when the terminal can obtain coarse synchronization or receive a response signal sent by the target cell, it can also send an uplink signal carrying discovery information and / or trigger information on a specific beam based on the coarse synchronization and / or the response signal.

[0474] In some embodiments, the method of the present disclosure further includes:

[0475] Acquiring a response signal to the uplink signal;

[0476] The response signal carries at least one of the following:

[0477] confirmation information of the uplink signal;

[0478] Feedback information on the uplink signal;

[0479] A second reference signal and / or a second channel, where the second reference signal is used as a reference signal for determining whether the terminal will subsequently wake up a dormant cell or as a reference signal for providing a specific function for the terminal, for example, synchronization, measurement, or positioning;

[0480] cell information of the cell that sends the response signal;

[0481] Specific cell information.

[0482] In some embodiments, the second reference signal includes at least one of the following: PSS, SSS, SSB, TRS, PRS, PT-RS, SRS, DMRS, CSI-RS.

[0483] In some embodiments, the second channel includes at least one of the following: PUCCH, PDCCH, PBCH, PRACH, PSSCH, PDSCH, PUSCH.

[0484] In the embodiment of the present disclosure, the uplink signal may include at least one uplink signal, and the response signal includes the response signal indicating the at least one uplink signal. The at least one uplink signal may be sent simultaneously or in a certain order.

[0485] For example, the above-mentioned uplink signal includes two uplink signals, a first signal and a second signal. The first signal carries discovery information, or carries discovery information and trigger information, and the second signal carries trigger information, or carries discovery information and trigger information. That is, the first signal and the second signal can be the same, such as both carrying discovery information and trigger information, or they can be different, such as the first signal carries discovery information and the second signal carries trigger information. And the signal types of the first signal and the second signal can be the same or different. For example, the first signal is a modulated signal based on OOK / ASK / FSK / PSK, and the second signal is an uplink control signaling or uplink reference signal based on NR.

[0486] The terminal sends a first signal, and the network-side device detects the first signal. When the signal information of the first signal meets specific conditions, a response signal to the first signal is sent. For example, when the amplitude / phase / power / energy of the first signal meets a specific threshold or a specific value, a response signal to the first signal is sent. The response signal to the first signal can be a modulation signal based on OOK / ASK / FSK / PSK, or a specific reference signal. The terminal then sends a second signal, which can be sent at a specific time interval after receiving the response signal to the first signal sent by the cell, and can be sent at a specific time interval with the sending time of the first signal. The trigger information carried by the first or second signal can be obtained through one or more methods such as neighboring cell high-level signaling configuration, core network signaling configuration, broadcast signaling, and protocol limitation.

[0487] The information carried by the first signal and / or the second signal may be explicitly indicated or implicitly indicated. After the target cell receives the first signal, sends a response signal, or receives the second signal, it is awakened or triggers the sending / receiving of a specific reference signal, or switches to the target cell state according to the corresponding signal and / or the information carried therein.

[0488] In some embodiments, there is a certain time offset between the first signal and the second signal, and the time offset can be determined based on at least one method such as a specific timer, high-layer signaling pre-configuration, protocol definition, terminal pre-storage, etc.

[0489] In the embodiment of the present disclosure, the network side device may perform the first signal detection in the following manner.

[0490] When the base station detects the first signal, it obtains one of the following related information: amplitude, phase, power, or energy. For example, it obtains the power value P of the signal, the amplitude value A of the signal, the energy value E of the signal, or the phase information θ of the signal. Assuming that the specific condition is greater than a 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, the base station determines that the current terminal is within the service range of the base station. Otherwise, the base station determines that the current terminal is not within the service range of the base station.

[0491] Assuming that the specific condition is greater than the amplitude threshold value A0, if the base station detects that the amplitude value A of the first signal is greater than the amplitude threshold value A0, it determines that the current terminal is within the service range of the base station; otherwise, the base station determines that the current terminal is not within the service range of the base station.

[0492] Assuming that the specific condition is greater than the energy threshold value E0, if the base station detects that the energy value E of the first signal is greater than the energy threshold value E0, it determines that the current terminal is within the service range of the base station; otherwise, the base station determines that the current terminal is not within the service range of the base station.

[0493] Assuming a specific condition of being within the phase value range {Θmax, Θmin}, if the base station detects that the phase value θ of the first signal is within this phase value range, the base station determines that the current terminal is within the base station's service range. Otherwise, the base station determines that the current terminal is not within the base station's service range. For example, when the terminal transmits the first signal, it can perform different phase modulations on base stations in different directions, with {0, π} representing a cell in one direction and {π, 2π} representing a cell in another direction. The base station performs coherent demodulation on the received signal to obtain the phase value range of the first signal.

[0494] Assuming that the specific condition is that the indication information carried by the first signal is a specific value, such as: all N bits are 1. If the base station detects that the indication information carried by the first signal meets the specific value, it is determined that the current terminal falls within the service range of the base station; otherwise, the base station determines that the current terminal does not fall within the service range of the base station.

[0495] When the base station determines that the current terminal is within the service range of the base station, the dormant cell is awakened and sends SSB signals, or CSI-RS or reference signals for positioning to provide regular services to the terminal; otherwise, the dormant cell will not be awakened.

[0496] In an embodiment of the present disclosure, when a terminal transmits a first signal, the terminal may also transmit a second signal to further provide additional information to the base station. The additional information may include at least one of the following: enhanced or supplementary information about the first signal, i.e., information that improves reception performance of the first signal or provides supplementary information about the first signal.

[0497] For information about the second signal used to improve reception performance of the first signal, such as when the second signal is a duplicate of the first signal or carries information related to the first signal, but the first and second signals are different signals, the terminal sending the second signal can improve the base station's ability to discover the terminal and obtain information carried by the first and / or second signals.

[0498] The second signal is used to provide supplementary information about the first signal. For example, the first signal is transmitted based on a broadcast when the terminal and the base station are not synchronized or precisely synchronized, and serves as a signal for the base station to discover the terminal. The second signal can be sent as supplementary information for the terminal, such as the terminal version or terminal type, to enable the discovery of a target cell that can serve the terminal. After the base station detects the first signal, it detects the second signal. If the cell can provide service to the terminal, the cell is awakened as the target cell and triggered to send or receive the second object, triggering the switching to at least one of the second states. In this way, by sending the second signal, the accuracy of waking up or triggering the target cell can be improved, thereby improving network energy saving performance.

[0499] In some embodiments, the method of the present disclosure further includes:

[0500] At a first moment, sending and / or receiving a second object of the target cell;

[0501] The first moment includes at least one of the following:

[0502] A time interval of a first duration from the time of sending the uplink signal;

[0503] A time interval of a second length from a time interval of receiving a response signal of the uplink signal;

[0504] The target cell includes at least one of the following:

[0505] at least one cell indicated by the trigger information;

[0506] at least one cell that sends the response signal;

[0507] at least one cell indicated by the response signal;

[0508] The cell to which the terminal accesses;

[0509] The second object includes at least one of the following:

[0510] Synchronization signal / physical broadcast channel signal block SSB or system information block SIB1 sent by the target cell;

[0511] At least one of a reference signal and a channel sent by the target cell;

[0512] at least one of a first reference signal and a first channel indicated by the trigger information;

[0513] at least one of a reference signal and a channel corresponding to the specific function indicated by the trigger information;

[0514] At least one of a reference signal and a channel corresponding to the requirement information of the terminal indicated by the trigger information;

[0515] At least one of a reference signal and a channel corresponding to the target cell state indicated by the trigger information;

[0516] At least one of a reference signal and a channel under default parameter configuration;

[0517] At least one of a reference signal and a channel configured with parameters carried by a broadcast channel or a broadcast message of the access cell;

[0518] The response signal indicates a second reference signal and / or a second channel.

[0519] The above-mentioned reference signals include at least one of PSS, SSS, SSB, TRS, PRS, PT-RS, random access preamble, SRS, DMRS, CSI-RS, etc., and the above-mentioned channels include at least one of PUCCH, PDCCH, PBCH, PRACH, PSSCH, PDSCH, PUSCH, etc.

[0520] In the disclosed embodiment, an uplink signal is sent, the uplink signal carrying at least one of discovery information and trigger information; the discovery information is used to discover a terminal; the trigger information is used to at least one of the following: wake up a target cell; trigger the target cell to send and / or receive a first object, the first object including at least one of a first reference signal and a first channel; trigger the target cell to switch to a target cell state. Thus, the above-mentioned discovery information and / or trigger information can be used to wake up a dormant cell or trigger a dormant cell to wake up and provide services.

[0521] The solution of the present disclosure is described in detail below with reference to embodiments.

[0522] Example 1: Structure of a transceiver for an uplink signal (using the first signal and / or the second signal as an example for illustration);

[0523] As shown in Figures 3 and 4, the transmitter used by the terminal to send the above-mentioned first signal and / or second signal can be a transmitter independent of the transmitter of the uplink NR signal, or can be the same transmitter.

[0524] The receiver of the base station for receiving the first signal and / or the second signal can be a receiver independent of the receiver of the uplink NR signal, or can be the same receiver.

[0525] When the first signal and / or the second signal include signals with different functions, the transceivers (transceivers) of the different signals are different. For example:

[0526] The first signal (carrying discovery information and used to discover the terminal, which can also be described as a discovery signal) is an OOK / ASK / FSK / PSK modulated signal, and the signal transceiver is independent of the NR transceiver. The first signal includes at least an OFDM-based OOK / ASK / FSK / PSK signal.

[0527] The second signal (carrying trigger information, used to wake up the target cell; triggering the target cell to send and / or receive a first object, the first object including at least one of a first reference signal and a first channel; and / or triggering the target cell to switch to the target cell state, which signal can also be described as a trigger signal) is an OOK / ASK / FSK / PSK signal. The transceiver is independent of the NR transceiver, and can also be the same transceiver as the NR transceiver. The second signal can include at least an OFDM-based OOK / ASK / FSK / PSK signal.

[0528] The second signal (carrying trigger information for waking up the target cell; triggering the target cell to send and / or receive a first object, the first object including at least one of a first reference signal and a first channel; and / or triggering the target cell to switch to the target cell state) is a 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 NR of this signal is the same transceiver. The signal based on the NR signal includes an NR-based reference signal and at least one of the channels. Among them, the reference signal includes at least one of PSS, SSS, SSB, TRS, PRS, PT-RS, random access preamble, SRS, DMRS, CSI-RS, etc., and the channel includes at least one of PUCCH, PDCCH, PBCH, PRACH, PSSCH, PDSCH, PUSCH, etc.

[0529] In the embodiment of the present disclosure, when the receiver of the first signal and / or the second signal can be independent of the receiver of the uplink NR signal, the network side base station does not need to keep the corresponding NR receiver turned on, but only needs to detect the first signal and / or the second signal. The receiver of the signal only needs 1 / 10 of the power consumption of the NR receiver, which can achieve energy saving on the network side.

[0530] When the transmitter of the first signal and / or the second signal is the same transmitter as the transmitter of the uplink NR signal, the terminal can realize the function of base station discovery terminal only through the low-power transmitter.

[0531] When the transmitter of the first signal and / or the second signal is different from the transmitter of the uplink NR signal, the terminal only needs to send the first signal and / or the second signal through an independent transmitter, and this signal can be a relatively frequent and dense signal, thereby achieving the purpose of reducing the power consumption of the terminal.

[0532] When the first signal and / or the second signal is an OOK / ASK / FSK / PSK modulated signal based on OFDM, the architecture of the NR transceiver in the related technology can be utilized to further simplify the complexity of the transceiver, and the detection based on OOK / ASK / FSK / PSK modulation can greatly reduce the power consumption of the receiving end, thereby achieving energy saving.

[0533] Example 2: Method for obtaining uplink signal resource related information;

[0534] The terminal and / or base station may obtain uplink signal resource related information based on one or more of the following: terminal storage information, neighboring cell high-level signaling configuration information, core network signaling configuration information, broadcast signaling information, and protocol-defined information.

[0535] For example:

[0536] The terminal needs to obtain resource-related information after the terminal is turned on to enable the terminal to be discovered and / or triggered. Specifically, this can be done in at least one of the following ways:

[0537] Method 1: The Subscriber Identity Module (SIM) card contains the Public Land Mobile Network (PLMN) identifier and operating frequency, along with stored PLMN-related information. The center frequency of the uplink signal can be a frequency that has a specific relationship with the PLMN's operating frequency. For example, if the SIM card stores PLMN-related information, when the terminal is powered on, it can perform a frequency search based on the PLMN information stored in the SIM card.

[0538] Method 2: Retrieve information based on pre-stored information in the uplink signal transceiver / transmitter. This can include pre-stored information in the uplink signal transceiver / transmitter, information written into the uplink signal dedicated chip, etc. For example, when the uplink signal transceiver / transmitter is powered on, the pre-stored information can be read. Alternatively, the information can be read from the dedicated uplink signal chip inserted into the device.

[0539] Method 3: Information acquisition based on core network signaling configuration. For example, serving cells under the same operator will carry uplink signal resource information via non-access stratum (NAS) signaling. Here, core network signaling can carry uplink signal generation information and / or time / frequency / space resource location information.

[0540] For example: NAS message in the PLMN selection process.

[0541] It should be noted that when the terminal receives the NAS message, since the NAS message is transparently transmitted in the RRC message, it is assumed that the terminal has completed synchronization, measurement, and reception of the broadcast message.

[0542] Method 4: Acquire through the configuration of the adjacent serving cell's high-layer signaling. For example, in a carrier aggregation (CA) scenario, the SIB information in the anchor cell carries the resource-related information.

[0543] Method 5: Configure SIB1 to obtain resource-related information through broadcast signaling sent by the dormant cell. For example, a dormant cell still sends SIB1 information with a long period in the dormant state, and resource-related information is carried in the SIB1 information.

[0544] Method 6: Determine resource-related information through protocol-defined default parameter configurations, such as the default frequency, bandwidth, or the center frequency used by the terminal during cell search. This includes the default frequency and bandwidth used by terminals of specific versions or those that support terminal wake-up or base station triggering.

[0545] It should be noted that when the terminal cannot synchronize with the dormant base station, the uplink signal resource information can only be obtained based on a priori information and / or relevant information provided by neighboring cells. The a priori information includes at least one of the following: information obtained from at least one of the SIM card, a dedicated SIM card for uplink signal-specific signals, the core network, and neighboring cells.

[0546] When the terminal can obtain initial synchronization with the dormant base station, such as when the dormant cell sends extremely sparse SSB information, the terminal can obtain a certain initial synchronization, or obtain corresponding synchronization information by sending SSB through the co-located neighboring cell.

[0547] Example 3: Information carried by uplink signals;

[0548] When the uplink signal is used as a discovery signal (carrying discovery information), the terminal sends the uplink signal at a specific resource location for the base station to discover the terminal, and / or the base station determines whether to be awakened based on the uplink signal.

[0549] When an uplink signal (carrying discovery information and trigger information) is received, the terminal sends an uplink signal at a specific resource location and carries corresponding information for the base station to discover the terminal, and / or determine whether to be awakened and / or send and / or receive the first object based on the uplink signal, and / or trigger the target cell to switch to the target cell state. After the base station receives the uplink signal, at least one of the following situations may occur:

[0550] Case 1: After receiving an uplink signal, the base station is directly awakened if it determines that specific conditions are met. Specifically, the base station sends / receives reference signals / channels / messages according to the default parameter configuration. Here, specific conditions can include: the amplitude / phase / power / energy of the signal meeting a specific threshold, a specific value, or a specific value range.

[0551] Case 2: After the base station receives the uplink signal and determines that specific conditions are met, it sends a specific reference signal according to the pre-configured or protocol-defined parameter configuration. Here, the reference signal can be at least one of SSB, SIB1, TRS, CSI-RS, SRS, PRS, PT-RS, etc. The pre-configured or protocol-defined parameter configuration can be a parameter configuration different from that of the base station in the normal state, or a dedicated parameter configuration in the energy-saving state, or at least one parameter configuration pre-defined by the protocol. Taking SSB as an example, when the base station is in a dormant or energy-saving state, it does not send SSB signals or sends extremely sparse SSB signals, such as a 640ms period. When the base station detects an uplink signal and meets specific conditions, the base station sends the SSB signal according to the default configuration, such as 20ms at the same time, or sends SSB based on a specific parameter configuration, such as a 320ms or 160ms period, or sends SSB according to the default configuration within a specific time period.

[0552] The specific conditions may be: the amplitude / phase / power / energy of the signal, etc., meets a specific threshold or a specific value or a specific value range.

[0553] Case 3: After the terminal sends an uplink signal, it receives a specific reference signal after a specific time interval according to a pre-configured or protocol-defined parameter configuration. Here, the reference signal can be at least one of SSB, SIB1, TRS, CSI-RS, SRS, PRS, PT-RS, etc. The pre-configured or protocol-defined parameter configuration can be a parameter configuration different from that of the base station in the normal state, a parameter configuration exclusive to the energy-saving state, or at least one parameter configuration pre-defined by the protocol. Taking SSB as an example, after a specific time interval (such as the default T ms) after the terminal sends an uplink signal, the terminal receives the SSB signal at a default 20ms period, or receives the SSB based on a specific parameter configuration, such as a 320ms or 160ms period, or sends the SSB according to the default configuration within a specific time period.

[0554] The specific time interval may be determined by at least one of protocol definition, high-layer signaling configuration, core network signaling indication, or terminal pre-storage.

[0555] Case 4: The base station may also be awakened according to the information carried by the uplink signal; or send and / or receive the indicated specific signal and / or channel.

[0556] Case 5: The terminal may also send and / or receive the indicated specific signal and / or channel according to the information carried by the uplink signal.

[0557] The uplink signal can carry at least one of the following information:

[0558] The sequence information of the specific information, that is, the sequence information defined by the protocol or pre-configured, is used by the base station for signal detection.

[0559] First indication information, such as indication information for waking up a cell, is used to indicate whether to wake up a dormant cell;

[0560] Second indication information, such as specific reference signal transmission / reception indication information, is used to indicate a specific reference signal to be transmitted / received by a cell;

[0561] The third indication information, such as cell state indication information, is used to instruct the cell to switch between at least one state, or to switch to a target cell state;

[0562] Fourth indication information, such as cell identity related information, is used to indicate cell information related to wake-up or transmission / reception of uplink signals / channels;

[0563] Fifth indication information, such as function trigger indication information, is used to instruct the cell to enable or disable specific functions, such as access, measurement, synchronization, positioning, energy saving, and specific service transmission;

[0564] Sixth indication information, such as a terminal-specific identifier, is used to indicate a specific type of the terminal or a terminal identifier;

[0565] The seventh indication information, such as the terminal demand information related identifier, is used to indicate the current service demand of the terminal, such as access, measurement, synchronization, positioning, energy saving, specific service transmission, etc.

[0566] The following is a detailed description of the information carried by the uplink signal:

[0567] (1) The uplink signal is a modulated signal sequence with a specific pattern, which is used by the base station to receive and perform signal detection. For example, a modulated signal with a specific sequence is used by the base station to perform uplink signal recognition when receiving the uplink signal detection.

[0568] It can be understood that the uplink signal does not carry other information and only provides the base station with relevant information for energy detection. For example:

[0569] (1) The uplink signal is a fixed pattern sequence of length N, such as N consecutive all-1 sequences, which are repeated 2 times. K After the K-order modulation (i.e., OOK / ASK / FSK / PSK modulation), a modulation sequence of length N or N / (K-1) is generated. N is an integer greater than or equal to 1.

[0570] For example, in an OOK signal, a "1" is modulated into a symbol with an amplitude of A, and a "0" is modulated into a symbol with an amplitude of 0 or a value other than A. The base station uses envelope demodulation for signal detection. If envelope demodulation satisfies specific conditions, such as detecting a signal with accumulated energy for a period of time T or a duration of T1 that meets an amplitude threshold, the uplink signal is considered to meet the specific conditions. This method carries a single piece of information.

[0571] For example, in an ASK signal, a "1" is modulated into a symbol with an amplitude of A, and a "0" is modulated into a symbol with a non-amplitude of A. The base station uses envelope demodulation for signal detection. If envelope demodulation satisfies specific conditions, such as detecting a signal with accumulated energy for a period of time T or a duration of T1 that meets an amplitude threshold, the uplink signal is considered to meet the specific conditions.

[0572] For example, in an FSK signal, a "1" is modulated on a symbol at frequency F1, and a "0" is modulated on a symbol at frequency F2. Alternatively, a "1" is modulated on a symbol at frequency band B1, and a "0" is modulated on a symbol at frequency band B2. The base station uses filtering and demodulation for signal detection. If the symbol energy at different frequencies or bandwidths obtained through filtering and demodulation meets the amplitude threshold for a signal duration of T1, the uplink signal is determined to meet specific conditions.

[0573] The uplink signal is a sequence of a specific pattern with a length of N, such as a sequence in which the bit "1" has a certain time proportion, "1010...10" or "1...10...0". K After OOK / ASK / FSK / PSK modulation, a modulation sequence of length N or N / (K-1) is generated. This method can carry corresponding information through different sequences, but the probability of false detection in this case is relatively high. N is greater than or equal to 1.

[0574] (2) The uplink signal carries first indication information (such as wake-up cell indication information);

[0575] The wake-up cell indication information is 1-bit information used to indicate that the target cell is awakened. That is, a value of "1" indicates waking up the target cell, and a value of "0" indicates that the target cell does not need to be awakened. The wake-up cell indication information can be sent based on specific parameter configurations.

[0576] The wake-up cell indication information can be carried by a discovery signal (e.g., an uplink signal that only carries discovery information). That is, if the target cell detects the discovery signal, the target cell is awakened; otherwise, the target cell is considered not awakened. In other words, the wake-up cell indication information is implicitly indicated by the discovery signal.

[0577] The wake-up cell indication information may also be N-bit information, where N is an integer greater than 1, such as an N-bit sequence of a specific pattern. The terminal sends at a pre-configured or protocol-defined resource location, and the pattern sequence of the specific N-bit information may be pre-stored or pre-configured. The wake-up cell indication information may be sequence information cascaded with the discovery signal, or sequence information of a resource location pre-configured or protocol-defined after the sequence information of the specific information. For example, after receiving the discovery signal, the base station obtains the discovery signal and demodulates it to carry the wake-up cell indication information. For example, if the pattern sequence carried by the discovery signal is consistent with the pre-stored or pre-configured pattern sequence, the target cell is considered to be awakened; otherwise, the target cell is considered not to be awakened.

[0578] (3) The uplink signal carries at least one of the following indication information: cell identification information, function identification, specific reference signal, cell status indication information, etc.

[0579] The uplink signal may also carry trigger information, including at least one of: cell identification related information, first object sending / receiving indication information, function trigger indication information, terminal demand information related identification, cell status indication information, etc. The above indication information may be indicated separately or in combination. The following specific examples are provided:

[0580] When the above instructions are provided as separate instructions, the following are examples of typical use cases:

[0581] Example 1: Uplink signal carries cell identification information:

[0582] The terminal can obtain in advance relevant information about cells that can be awakened or triggered, such as a frequency list, a cell list, etc. Based on the pre-configured or pre-acquired cell-related information, it can be classified according to the cell-related information, corresponding to different frequency cells, or corresponding to different cell IDs, or corresponding to the index values ​​of different cells on the cell list. Different classifications generate different sequences, such as different OOK modulation pattern modulation symbol sequences corresponding to different cells or cell groups, or ASK modulation symbol sequences with different amplitude patterns corresponding to different cells or cell groups, or FSK modulation symbol sequences with different frequency domain patterns corresponding to different cells or cell groups. If the terminal can obtain the target cell ID or the index value of the cell list where the target cell is located, an uplink signal is generated according to the target cell ID or the index value of the cell list where the target cell is located. The terminal sends an uplink signal carrying cell identification related information to the surrounding base stations.

[0583] The base station receives the uplink signal and performs OOK / ASK / FSK / PSK modulation sequence detection. If the cell-related information carried in the uplink signal is consistent with the pre-configured or pre-acquired cell-related information, the base station considers the current cell to be the target cell triggered by the uplink signal. The target cell then transmits specific signals and / or channels based on the trigger information carried in the uplink signal and / or protocol specifications.

[0584] For example, in the related art system, there are 1008 physical cell identifiers (PCIs). If only If cell identification is performed, the uplink signal only needs to carry 7 bits of information.

[0585] Example 2: An uplink signal carries specific reference signal transmission and / or reception indication information. If the uplink signal is used to trigger the transmission and / or reception of some reference signals of the base station, the uplink signal may carry indication information of at least one reference signal. Different reference signals are indicated using Si bits, for example, as shown in Table 1:

[0586] Table 1

[0587] When each reference signal indication information has only 1 bit, the value "0 or 1" can be used to indicate "send / not send" of the corresponding reference signal.

[0588] When each reference signal indication information has greater than or equal to 1 bit, one of the values ​​is used to indicate a specific set of parameters in at least one set of parameter configurations of the corresponding reference signal, or a specific value is used to indicate "send / not send" of the corresponding reference signal.

[0589] If the uplink signal is used to trigger the transmission of some reference signals of the base station, the uplink signal may carry indication information of at least one reference signal, and different reference signals are jointly indicated through N bits, as shown in Table 2 for example:

[0590] Table 2

[0591] Example 3: Uplink signal carries different function indication information;

[0592] When the uplink signal carries information indicating different functions, such as indicating at least one of the functions such as wake-up, measurement, synchronization, and positioning, different functions can be indicated by one bit respectively, or at least one function can be jointly indicated by at least one value or pattern among N bits.

[0593] For example, Y1, Y2, Y3, ..., YN are greater than or equal to 1. When the indication information is 1 bit, it can indicate that the function is "on / maintained" or "off", as shown in Table 3.

[0594] Table 3

[0595] Among them, different functions correspond to the transmission and / or reception of a reference signal configured with at least one specific parameter, as shown in Table 4.

[0596] Table 4

[0597] Here, the specific function indication may be the sending and / or receiving of a specific reference signal under at least one specific parameter configuration.

[0598] For example: when the function indication is a wake-up function, and / or the function indication information indicates "wake-up", the terminal can receive SSB / SIB1, paging, TRS, PEI signaling, etc., or send at least one of a random access (RA) request, a scheduling request SR, etc. after a certain time interval after sending the indication information.

[0599] For another example, when the function indication is a positioning function, and / or the function indicates the transmission and / or reception of a reference signal configured with at least one specific parameter, the terminal may receive at least one of an SSB, a TRS, a PRS, and transmit an SRS after a certain time interval after sending the indication information, where the parameter configuration may be pre-configured or protocol-defined.

[0600] For another example, when the function indication is measurement, and / or the function indicates the transmission and / or reception of a reference signal configured with at least one specific parameter, the terminal may receive at least one of SSB, TRS, CSI-RS, PT-RS, etc., a certain time interval after sending the indication information, where the parameter configuration may be pre-configured or protocol-defined.

[0601] At least one function may also be jointly indicated by at least one value or pattern in the N bits, as shown in Table 5:

[0602] Table 5

[0603] Example 4: The uplink signal carries terminal demand information related identification information, that is, it is used to indicate the current service requirements of the terminal, such as access, measurement, synchronization, positioning, energy saving, specific service transmission, etc. The terminal demand information related identification information is similar to the function indication information. For details, please refer to the indication method of the function indication information, which will not be repeated here. The base station receives the terminal demand information related identification information and can further determine whether to provide the corresponding service to the user based on its needs. In some embodiments, it sends its response information to the terminal to further indicate whether to provide the corresponding service to it. In addition, the service type can be further indicated, such as: Extended Reality (XR) service, Enhanced Mobile Broadband (eMBB) service, Ultra-Reliable & Low-Latency Communication (URLLC) service, massive Machine Type of Communication (mMTC) service, Artificial Intelligence & Internet of Things (AIoT) service, and other service type corresponding indication information. The base station receives relevant indication information such as the service demand of the terminal, and then further determines whether to be awakened or triggered to send and / or receive corresponding reference signals / channels based on the indicated information.

[0604] Example 5: Uplink signal carries cell status indication information;

[0605] When the uplink signal carries different cell status indication information, such as at least one of the cell states such as energy-saving state 1, energy-saving state 2, ..., and normal state, the different cell states can be indicated using Xi bits respectively, or at least one function can be jointly indicated by at least one value or pattern in N bits. The following examples are provided:

[0606] For example, X1, X2, X3, ..., XN are greater than or equal to 1. When the indication information is 1 bit, it can indicate the cell status as "on / maintain" or "off", as shown in Table 6.

[0607] Table 6

[0608] Different cell states correspond to the transmission and / or reception of a reference signal configured with at least one specific parameter, as shown in Table 7.

[0609] Table 7

[0610] (4) The uplink signal carries a terminal-specific identifier.

[0611] The uplink signal carries terminal-specific identification information, which can be a terminal type identifier, a terminal version identifier, or a terminal that supports a specific service, such as a terminal identifier that supports delay-sensitive services (such as XR services) or a terminal identifier for a dormant base station-specific service. When the base station receives an uplink signal containing a terminal-specific identifier that indicates the terminal needs to be served by the current dormant cell, the cell is awakened or the transmission and / or reception of a specific reference signal and / or is triggered.

[0612] Example 4:

[0613] When the uplink signal carries discovery information and trigger information, it can respectively carry specific sequence information for the base station to perform uplink signal detection, and carry trigger information of the target cell. Here, the trigger information can be explicitly indicated or implicitly indicated. For explicit indication, when the sequence information of the uplink signal meets specific conditions, the base station demodulates it to obtain the trigger information. For example, the uplink signal can be sent periodically, or semi-continuously, or repeatedly within a sending window. The base station detects the amplitude / energy / frequency / bandwidth / phase of the uplink signal within the detection window. When the corresponding threshold requirements are met, the uplink signal is demodulated / parsed to obtain the trigger information therein. For implicit indication, when the base station detects that the sequence information of the uplink signal meets specific conditions, the base station is awakened, triggered to send / receive the first object, switched to a cell-specific state, etc., at least one of the following.

[0614] When the uplink signal carries trigger information, one or more pieces of trigger information may be carried through specific sequence information, as shown in Table 8.

[0615] Table 8

[0616] Example 5: Resource location information of uplink signal;

[0617] The resource location of the uplink signal, including: time domain / frequency domain / space domain / code domain, can be obtained through at least one of the terminal memory, neighboring cell high-level signaling configuration, core network signaling configuration, broadcast signaling, etc. The uplink signal has at least one of the following characteristics:

[0618] Item 1: The time domain resource location of the uplink signal can be sent periodically or semi-continuously. The base station can detect the uplink signal continuously or based on a detection window, depending on the base station implementation.

[0619] The transmission period of the uplink signal may be a default period, such as defined by a protocol, or consistent with the default period of a specific reference signal, such as the default period of 20 ms for SSB.

[0620] When the uplink signal is semi-persistently transmitted, the terminal may start transmitting when it needs to wake up or trigger a specific cell to provide service for it. The transmission time of the uplink signal may be based on the system frame number (SFN).

[0621] The second item: The uplink signal is sent within a specific time window. This time window can be a repeated transmission time window (as shown in Figure 5), a duration window of the uplink signal (as shown in Figure 5), or a specific pattern transmission within the time window (as shown in Figure 6).

[0622] Item 3: When the uplink signal carries trigger information, there is an association relationship between it and a specific reference signal.

[0623] For example, the terminal obtains the potential location of the SSB that can be sent by the dormant cell from the neighboring cell. When the terminal needs the dormant cell to send the SSB, it sends an uplink signal at a position with a certain offset value from the SSB to trigger the dormant cell to send the SSB.

[0624] For example, if the terminal detects the SSB sent by the target cell, it will send an uplink signal at a certain offset from the SSB to trigger the sending of a specific reference signal of the target cell or trigger the energy-saving state of the cell, as shown in Figure 7:

[0625] For example, based on higher-layer signaling or core network signaling from neighboring cells or historical serving cells, the terminal learns the locations (occasions) of the dormant cell's SSB / SIB1 / TRS to be transmitted. It then sends an uplink signal at a certain interval (GAP) between the location and the specific reference signal to trigger whether the dormant cell should transmit the corresponding reference signal. This interval is determined based on an offset value (Offset), as shown in Figure 8.

[0626] Item 4: The uplink signal includes a first signal (carrying discovery information, which can also be described as a discovery signal) and a second signal (carrying trigger information, which can also be described as a trigger signal). There is an association relationship between the first signal and the second signal, and the association relationship can be determined based on the offset value (Offset), as shown in Figure 9:

[0627] When the first signal and the second signal are two independent signals, there is a certain time offset between the first signal and the second signal. The second signal can correspond one-to-one with the first signal, that is, the two have the same transmission period, or the second signal can be transmitted at least one after the first signal, that is, the period of the second signal is N times the period of the first signal.

[0628] When the first signal and the second signal are the same signal, the second signal may be part or all of the first signal. For example, if the discovery information sequence occupies N time slot symbols, the trigger information may be K time slot symbols therein. The trigger information may be K time slot symbols starting from a specific position, the first K or last K time slot symbols in the discovery information, or K time slot symbols having a certain pattern, where K is less than or equal to N.

[0629] Example 6:

[0630] When sending an uplink signal carrying trigger information, the terminal needs to obtain resource-related information of the corresponding signal, including generation-related information of the signal, sent resource information, and one or more related information carried by the signal.

[0631] Uplink signal generation-related information is used by both the sender and receiver to determine / detect the uplink signal transmission location, including at least the uplink signal transmission frequency, bandwidth, number of occupied time domain units, number of at least one segment, number of IFFT points, and uplink signal sequence length. The frequency can be the operating frequency, center frequency, or service frequency of the uplink signal.

[0632] For example:

[0633] The uplink signal is an OOK-1 signal: Determine the center frequency of the signal's frequency domain, the number of carriers, the subcarrier spacing (SCS), the number of symbols (or uplink signal duration), and the number of IFFT points. The center frequency can be the initial access frequency / initial BWP.

[0634] In the above-mentioned OOK-1 signal, as shown in FIG10 , the low power wake-up signal (LP-WUS) includes N subcarriers (SC). After performing an inverse fast Fourier transform (IFFT) and adding a cyclic prefix (CP) operation on the LP-WUS, one OFDM symbol corresponds to a single bit.

[0635] The subcarrier (SC) of the low power wake-up signal (LP-WUS) is:

[0636] OOK=1 means that all SCs are used for modulation, corresponding to bit "1", or any one or several corresponding bits of K-order modulation symbols are "1";

[0637] OOK=0 means that all SCs are zero power (from the perspective of baseband), corresponding to bit "0", or any one or several corresponding bits "0" of the K-order modulation symbols.

[0638] When the uplink signal is an OOK-1 signal, this 1-bit information can be used to trigger the signal of one OFDM symbol. To enable the base station to detect the terminal, this signal can be repeated N times. The base station receiver can detect the user's signal continuously or at specific time intervals. The specific detection method depends on the base station implementation or is based on relevant information about the uplink signal sent by the terminal.

[0639] The uplink signal is an OOK-2 signal: determine the number of signal segments M (which can be related to the symbol length and duration occupied by the signal), a maximum of M center frequencies, the SCS, the number of carriers in each segment, the number of OFDM symbols (or uplink signal duration), and the number of IFFT points.

[0640] In the above OOK-2 signal, the N SCs of the LP-WUS are further divided into M segments, each containing N / 2 subcarriers, as shown in Figure 11, where M = 2, and there may be guard bands in between and / or around them. After performing an inverse fast Fourier transform (IFFT) and adding a cyclic prefix (CP) to the LP-WUS, the LP-WUS corresponds to M-bits of parallel OOK in the frequency domain. The SC of the LP-WUS is:

[0641] OOK=1 means that all SCs in the segment have been modulated, corresponding to bits "1", or any one or several corresponding bits "1" of the K-order modulation symbol;

[0642] OOK=0 means that all SCs in the segment are zero power (from the baseband point of view), corresponding to bit "0", or any one or several corresponding bits "0" of the K-order modulation symbol.

[0643] When the first signal is an OOK-2 signal, M bits in the frequency domain can carry a terminal discovery signal. For example, if the first signal is a specific sequence, such as M bits of 1, the base station can detect the terminal based on a specific sequence pattern, such as "1010...1." The base station receiver can detect the user's signal continuously or during specific time periods. The specific detection method depends on the base station implementation or is based on information about the uplink signal sent by the terminal.

[0644] The uplink signal is an OOK-3 signal: determine the number of signal segments L, SCS, the number of carriers in each segment, the number of OFDM symbols (or uplink signal duration), and the number of IFFT points.

[0645] The N SCs of the LP-WUS are divided into L segments, as shown in Figure 12, where L = 2. There are no guard bands between segments, but there may be guard bands around segments. After performing an inverse fast Fourier transform (IFFT) and adding a cyclic prefix (CP) to the LP-WUS, a multi-tone single-bit OOK signal is obtained. In Figure 12, t0 and t1 represent the SC sequences corresponding to 0 and 1, respectively:

[0646] OOK=1 means that one subcarrier of each segment (known to the UE) is modulated, and the rest of the SC is zero power (from the baseband point of view), corresponding to bit "1";

[0647] OOK=0 means that all SCs in all segments are zero power (from the baseband point of view), corresponding to bit "0".

[0648] If the first signal is an OOK-3 signal, it can carry the same frequency domain sequence information in different segments, or carry different frequency domain sequence information in different segments. Under certain time / frequency domain deviations on the base station side, the receiver can continuously detect in the time domain, and / or perform frequency domain scanning to detect the first signal; it can also detect the user's signal within a specific time period or within a specific frequency domain resource range. The specific detection method depends on the base station implementation, or is based on the relevant information of the first signal sent by the terminal. The uplink signal is an OOK-4 signal: determine the symbol length and duration occupied by the uplink signal, the frequency domain center frequency, SCS, the number of frequency domain carriers, etc., and the number of IFFT points.

[0649] As shown in Figure 13, N' samples are generated from M bits. The N SCs of the LP-WUS are generated through a transform (DFT / least squares). Signal modulation may or may not be used. Truncation or other additional modulation may or may not be used. If no additional modulation is used, N and N' are the same. After performing an inverse fast Fourier transform (IFFT) and adding a cyclic prefix (CP) on the LP-WUS, OOK-4 is obtained.

[0650] OOK-4 can be considered as an example of an OOK signal based on a single carrier (such as DFT-S-OFDM), and can also be used as a signal generation method independent of an uplink single carrier (such as DFT-S-OFDM).

[0651] Example 7: A process for sending an uplink signal (taking the first signal and the second signal as an example);

[0652] Implementation method 1: The base station is awakened after receiving the uplink signal;

[0653] As shown in Figure 14, the process includes:

[0654] Step 1: The terminal sends a first signal for the surrounding dormant cells / base stations (such as Pico base stations) to discover the terminal, where the discovery signal is an OFDM-based OOK / ASK / FSK / PSK signal. The first signal can be sent through a dedicated transmitter or through an NR transmitter. The first signal can be sent N times at a specific time point or time period, where N is greater than or equal to 1. The specific sending location can be determined by one or more methods such as neighboring cell high-level signaling configuration, core network signaling configuration, broadcast signaling, or protocol limitation.

[0655] Step 2: The base station performs a first signal detection and obtains information carried by the first signal, including signal information and / or carried indication information. If the first signal meets a specific condition (i.e., the first condition), the cell is directly awakened, or if the first signal does not meet the specific condition, the cell will not be awakened. Here, the above-mentioned first signal can carry M bits of information, where M is greater than or equal to 1, and the information carried includes at least one of the following:

[0656] Signal amplitude / phase / power / energy and other related information;

[0657] Instruction information used to wake up the cell.

[0658] In this embodiment, the first signal can be received by a dedicated receiver or an NR receiver.

[0659] For example:

[0660] Assuming that the first signal is an OOK signal based on OFDM, when the base station detects the first signal, it obtains one of the related information such as amplitude / phase / power / energy, such as: obtaining the power value of its signal as P, or obtaining the amplitude value of its signal as A, or obtaining the energy value of its signal as E, or obtaining the phase information of its signal as θ.

[0661] Assume that the first signal is an OFDM-based OOK signal, which carries N bits of indication information through modulation and the like, where N is greater than or equal to 1, and is used to indicate waking up the target cell.

[0662] Specifically, the specific condition may be: the amplitude / phase / power / energy of the signal, etc., meets a specific threshold or a specific value or a specific value range.

[0663] For example, assuming that the specific condition is greater than the power value threshold P0, if the base station detects that the power value P of the first signal is greater than the power value threshold P0, it determines that the current terminal falls within the service range of the base station; otherwise, the base station determines that the current terminal does not fall within the service range of the base station.

[0664] Assuming that the specific condition is greater than the amplitude threshold value A0, if the base station detects that the amplitude value A of the first signal is greater than the amplitude threshold value A0, it determines that the current terminal is within the service range of the base station; otherwise, the base station determines that the current terminal is not within the service range of the base station.

[0665] Assuming that the specific condition is greater than the energy threshold value E0, if the base station detects that the energy value E of the first signal is greater than the energy threshold value E0, it determines that the current terminal is within the service range of the base station; otherwise, the base station determines that the current terminal is not within the service range of the base station.

[0666] Assuming a specific condition of being within the phase value range {Θmax, Θmin}, if the base station detects that the phase value θ of the first signal is within this phase value range, the base station determines that the current terminal is within the base station's service range. Otherwise, the base station determines that the current terminal is not within the base station's service range. For example, when the terminal transmits the first signal, it can perform different phase modulations on base stations in different directions, with {0, π} representing a cell in one direction and {π, 2π} representing a cell in another direction. The base station performs coherent demodulation on the received signal to obtain the phase value range of the first signal.

[0667] Assuming that the specific condition is that the indication information carried by the first signal is a specific value, such as: all N bits are 1. If the base station detects that the indication information carried by the first signal meets the specific value, it is determined that the current terminal falls within the service range of the base station; otherwise, the base station determines that the current terminal does not fall within the service range of the base station.

[0668] When the base station determines that the current terminal is within the service range of the base station, the dormant cell is awakened and sends SSB signals, or CSI-RS or reference signals for positioning to provide regular services to the terminal; otherwise, the dormant cell will not be awakened.

[0669] Step 3: If the cell is awakened, perform at least one of the following:

[0670] Restore service status;

[0671] Enter a light sleep state;

[0672] Send SSB / SIB1. The terminal performs synchronization, cell search, random access, or sends a scheduling request on the SSB sent by the wake-up cell.

[0673] Implementation method 2: After receiving the first signal, the base station is triggered to send / receive the first object;

[0674] As shown in Figure 15, the process includes:

[0675] Step 1: The terminal sends a first signal for the surrounding dormant cells / base stations (such as Pico) to discover the terminal, wherein the first signal is an OFDM-based OOK / ASK / FSK / PSK signal. The first signal can be sent through a dedicated transmitter or an NR transmitter. The first signal can be sent N times at a specific time point or time period, where N is greater than or equal to 1. The specific sending location can be determined by one or more methods such as neighboring cell high-level signaling configuration, core network signaling configuration, broadcast signaling, or protocol limitation.

[0676] Step 2: The base station performs a first signal detection and obtains information carried by the first signal, including signal information and / or carried indication information. If the first signal meets a specific condition (i.e., the first condition), the cell is triggered to send a specific reference signal, or if the first signal does not meet the specific condition, the cell does not send the specific reference signal. Here, the first signal can carry M bits of information, where M is greater than or equal to 1, and the information carried includes at least one of the following:

[0677] The signal information carried by the first signal may be related information such as the amplitude / phase / power / energy of the signal.

[0678] The indication information carried by the first signal is used to trigger the cell to receive and / or send signals.

[0679] In this embodiment, the first signal can be received by a dedicated receiver or an NR receiver.

[0680] For example:

[0681] Assuming that the first signal is an OOK signal based on OFDM, when the base station detects the first signal, it obtains one of the related information such as amplitude / phase / power / energy, such as: obtaining the power value of its signal as P, or obtaining the amplitude value of its signal as A, or obtaining the energy value of its signal as E, or obtaining the phase information of its signal as θ.

[0682] Specifically, the specific condition may be: the amplitude / phase / power / energy of the signal, etc., meets a specific threshold or a specific value or a specific value range.

[0683] For example:

[0684] Assuming that the specific condition is greater than the power value threshold P0, if the base station detects that the power value P of the first signal is greater than the power value threshold P0, it determines that the current terminal needs the base station side to send / receive a specific reference signal; otherwise, the base station determines that the current terminal does not need to send / receive a specific reference signal.

[0685] Assuming that the specific condition is greater than the amplitude threshold value A0, if the base station detects that the amplitude value A of the first signal is greater than the amplitude threshold value A0, it is determined that the current terminal needs the base station side to send / receive a specific reference signal; otherwise, the base station determines that the current terminal does not need to send / receive a specific reference signal.

[0686] Assuming that the specific condition is greater than the energy threshold value E0, if the base station detects that the energy value E of the first signal is greater than the energy value threshold value E0, it determines that the current terminal needs the base station side to send / receive a specific reference signal; otherwise, the base station determines that the current terminal does not need to send / receive a specific reference signal.

[0687] Assuming that the specific condition is within the phase value range {Θmax, Θmin}, if the base station detects that the phase value θ of the first signal is within the phase value range, it is determined that the current terminal needs the base station side to send / receive a specific reference signal; otherwise, the base station determines that the current terminal does not need to send / receive a specific reference signal.

[0688] For example, when the base station determines that the current terminal needs the base station side to send / receive a specific reference signal, the dormant cell sends a specific reference signal according to the protocol definition or according to the indication information carried by the first signal, such as: SSB signal, TRS signal, CSI-RS signal, reference signal PRS / SRS for positioning, etc.; conversely, the dormant cell or the cell in the energy-saving state will not send / receive a specific reference signal. The configuration of the reference signal is the default parameter configuration defined by the protocol. The specific reference signal can be one or more signals defined by the protocol, such as: when the protocol defines that the base station receives the first signal and meets specific conditions, it sends an SSB signal. The SSB signal is sent according to the default 20ms period. The same applies to other reference signals.

[0689] Assume that the specific condition is that the indication information carried by the first signal is the indication information of a specific reference signal, that is, different values ​​correspond to different reference signals, such as: N bits correspond to M reference signals respectively, and the base station triggers the sending and / or reception of the corresponding specific reference signal according to the indication information.

[0690] For example, when the base station receives a first signal, and the first signal carries indication information of a specific reference signal, such as the N1 bit in the N bits is 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. Furthermore, when the base station determines that the current terminal requires the base station side to send / receive a specific reference signal, the dormant cell can configure a parameter among multiple configurations of the specific reference signal according to the indication information. For example, when the base station receives the indication information carried by the first signal indicating the sending of the positioning reference signal PRS, and indicates a parameter configuration among the pre-configured parameter configurations, the base station sends the specific reference signal according to the specific parameter configuration.

[0691] Step 3: When the cell is triggered to send a specific reference signal, perform at least one of the following:

[0692] Send SSB / SIB1;

[0693] Send downlink synchronization signal TRS;

[0694] Send positioning reference signal.

[0695] The terminal performs synchronization, cell search, random access, or sends a scheduling request based on a specific reference signal sent by the dormant cell.

[0696] Implementation method three: The uplink signal includes a first signal and a second signal, the first signal carries discovery information, or carries discovery information and trigger information, and the second signal carries discovery information and trigger information, or carries trigger information. The base station is fully or partially awakened after sending a first response signal to the first signal;

[0697] As shown in Figure 16, it includes:

[0698] Step 1: The terminal sends a first signal for nearby dormant cells / base stations (e.g., Pico) to discover the terminal. The first signal is an OFDM-based OOK / ASK / FSK / PSK signal. The first signal can be sent via a dedicated first signal transmitter or an NR transmitter.

[0699] Step 2: The base station performs a first signal detection and obtains information carried by the first signal, including signal information and / or carried indication information. If the first signal meets a specific condition (i.e., the first condition), a first response signal is sent to the terminal. Alternatively, if the first signal does not meet the specific condition, the cell does not send the first response signal. Here, the first signal can carry M bits of information, where M is greater than or equal to 1, and the information carried includes at least one of the following:

[0700] Signal amplitude / phase / power / energy and other related information.

[0701] Indication information used to trigger the cell to receive and / or send signals.

[0702] In this embodiment, the first signal can be received by a dedicated receiver based on the first signal, or by an NR receiver.

[0703] For example:

[0704] Assuming that the first signal is an OOK signal based on OFDM, when the base station detects the first signal, it obtains one of the related information such as amplitude / phase / power / energy, such as: obtaining the power value of its signal as P, or obtaining the amplitude value of its signal as A, or obtaining the energy value of its signal as E, or obtaining the phase information of its signal as θ.

[0705] Taking the OOK-1 signal as an example, the first signal can carry 1 bit of information for terminal discovery in dormant cells. The first signal can be sent N times at a specific time point or time period, where N is greater than or equal to 1. The specific sending location can be determined by one or more methods, such as neighboring cell high-layer signaling, core network signaling, broadcast signaling, or protocol definition.

[0706] Step 3: The base station sends a first response signal to the first signal. Here, the first response signal may be sent by the base station when it detects that signal information of the first signal meets a specific condition. Specifically, the specific condition may be: the amplitude / phase / power / energy of the signal meets a specific threshold, a specific value, or a specific value range. The first response signal may also be sent by the base station upon detecting the first signal.

[0707] For specific conditions, please refer to Example 2 and Example 3.

[0708] The first response signal may carry at least one of the following:

[0709] The first item carries the confirmation information of the cell for receiving the first signal, for example, N-bit ACK information. Here, the first response signal can be an OFDM-based OOK / ASK / FSK / PSK signal.

[0710] For example, if a base station detects that the signal amplitude exceeds a specific threshold within a certain period of time, it determines that a terminal has entered the service range of the cell. Therefore, the base station determines that the terminal needs to be awakened and sends a first response signal to the terminal. For example, this signal carries a 1-bit OOK signal. After sending the first signal, the terminal performs reception detection of the first response signal within a specific time interval.

[0711] The second item carries cell information of the current cell. For example, the cell information may be a predefined sequence or signal pattern. Here, the first response signal may be an OFDM-based OOK / ASK / FSK / PSK signal. The predefined sequence or signal pattern corresponding to the cell information may be preconfigured by the terminal or defined by a neighboring cell, the core network, or a protocol.

[0712] For example, if a base station detects that a signal amplitude exceeds a specific threshold within a certain period of time, it determines that a terminal has entered the service range of the cell. Therefore, the base station determines that the terminal needs to be awakened and sends a first response signal to the terminal. This first response signal includes M bits of information corresponding to preconfigured or predefined cell information. After sending the first signal, the terminal performs reception detection of the first response signal within a specific time interval.

[0713] Item 3: Feedback information of the cell regarding the indication information carried by the first signal, for example, feedback information carried by the first signal.

[0714] For example: the N-bit information of the first signal carries indication information of M1 specific reference signals and / or M2 specific parameter configurations. When the base station side detects the first signal and meets specific conditions, it sends feedback information corresponding to the indication information to the terminal, that is, confirmation information of the m1-th specific reference signal indication information and / or confirmation information of the m2-th parameter configuration indication information.

[0715] Item 4: Reference signal used for terminal time and frequency synchronization, such as SSB signal.

[0716] For example, if a base station detects that the signal amplitude exceeds a specific threshold within a certain period of time, it determines that a terminal has entered the service range of the cell. Therefore, the base station determines that it needs to be awakened and sends a response signal to the terminal. The first response signal is a specific reference signal, such as the SSB signal used for terminal time and frequency synchronization.

[0717] Step 4: After the specific cell sends the first response signal, perform at least one of the following:

[0718] Restore service status, that is, fully awakened;

[0719] Enter a light sleep state;

[0720] Send SSB / SIB1;

[0721] Send downlink synchronization signal TRS;

[0722] Send positioning reference signal.

[0723] Step 5: After receiving the first response signal, the terminal receives the SSB or specific reference signal, performs synchronization, cell search, random access, or sends a scheduling request.

[0724] Implementation method four: the uplink signal includes a first signal and a second signal, the first signal carries discovery information, or carries discovery information and trigger information, and the second signal carries discovery information and trigger information, or carries trigger information.

[0725] As shown in Figure 17, the process includes:

[0726] Step 1: The terminal sends a first signal for nearby dormant cells / base stations (e.g., Pico) to discover the terminal. The first signal is an OFDM-based OOK / ASK / FSK / PSK signal. The first signal can be sent via a dedicated first signal transmitter or an NR transmitter.

[0727] Step 2: The base station detects the first signal and obtains information carried by the first signal, including signal information and / or carried indication information. Here, the information carried by the first signal includes at least one of the following:

[0728] The signal information carried by the first signal may be related information such as the amplitude / phase / power / energy of the signal.

[0729] The indication information carried by the first signal is used to trigger the cell to receive and / or send signals.

[0730] In this embodiment, the first signal can be received by a dedicated receiver based on the first signal, or by an NR receiver.

[0731] For example:

[0732] Assuming that the first signal is an OOK signal based on OFDM, when the base station detects the first signal, it obtains one of the related information such as amplitude / phase / power / energy, such as: obtaining the power value of its signal as P, or obtaining the amplitude value of its signal as A, or obtaining the energy value of its signal as E, or obtaining the phase information of its signal as θ.

[0733] Step 3: The base station sends a first response signal to the first signal. Here, the first response signal may be sent by the base station when it detects that signal information of the first signal meets a specific condition. Specifically, the specific condition may be: the amplitude / phase / power / energy of the signal meets a specific threshold, a specific value, or a specific value range. The first response signal may also be sent by the base station upon detecting the first signal.

[0734] For specific conditions, please refer to Example 2 and Example 3.

[0735] The first response signal may be at least one of the following:

[0736] The first item carries the confirmation information of the cell for receiving the first signal, for example, N bits of ACK information, which is used to indicate that the base station has detected the first signal.

[0737] The second item carries the cell information of the current cell, etc. For example, the cell information may be a predefined sequence or signal pattern.

[0738] Item 3: Feedback information of the cell regarding the indication information carried by the first signal, for example, feedback information carried by the first signal.

[0739] Item 4: a specific reference signal sent / received by a cell (ie, a second reference signal).

[0740] For example:

[0741] If the first signal is used to wake up the dormant cell, the base station sends a first response signal to confirm that the cell has been woken up.

[0742] If the first signal carries relevant information of the cell, the base station sends a first response signal to feedback whether it is the target cell for the terminal to wake up.

[0743] If the first signal carries indication information of the triggered sending / receiving of the first target reference signal, the base station performs feedback according to the indication information.

[0744] If the base station receives the first signal, it sends a first response signal to the terminal, including confirmation information and / or a specific reference signal, such as at least one of an SSB signal and a SIB signal.

[0745] Step 4: After receiving the first response signal, the terminal receives a specific reference signal (second reference signal), such as SSB, and performs synchronization and cell search. If the current cell meets the cell search or cell reselection conditions, the terminal sends a second signal to the accessed specific cell to wake up or trigger the transmission / reception of the specific reference signal. Here, the second signal can be an OFDM-based OOK / ASK / FSK / PSK signal or an NR signal.

[0746] For example:

[0747] If the second signal is an OFDM-based OOK / ASK / FSK / PSK signal, the generation method and the carried information may refer to the uplink signal in the sixth embodiment.

[0748] If the second signal is an NR signal, it can be an uplink control signaling based on PUCCH or an uplink reference signal based on a sequence. Among them, the uplink control signaling based on PUCCH is a dedicated signaling for cell wake-up.

[0749] The second signal may carry at least one of the following information:

[0750] First indication information, such as indication information for waking up a cell, is used to indicate whether to wake up a dormant cell;

[0751] Second indication information, such as specific reference signal transmission / reception indication information, is used to indicate a specific reference signal to be transmitted / received by a cell;

[0752] The third indication information, such as cell state indication information, is used to instruct the cell to switch between at least one state, or to switch to a target cell state;

[0753] Fourth indication information, such as cell identity related information, is used to indicate cell information related to wake-up or transmission / reception of uplink signals / channels;

[0754] Fifth indication information, such as function trigger indication information, is used to instruct the cell to enable or disable specific functions, such as access, measurement, synchronization, positioning, energy saving, and specific service transmission;

[0755] Sixth indication information, such as a terminal-specific identifier, is used to indicate a specific type of the terminal or a terminal identifier;

[0756] The seventh indication information, such as the terminal demand information related identifier, is used to indicate the current service demand of the terminal, such as access, measurement, synchronization, positioning, energy saving, specific service transmission, etc.

[0757] Step 5: After receiving the second signal indicating the sending / receiving of a specific reference signal for waking up or triggering the specific cell, the specific cell performs at least one of the following:

[0758] Restore service status, i.e. wake up;

[0759] Enter a light sleep state;

[0760] Send SSB / SIB1;

[0761] Send downlink synchronization signal TRS;

[0762] Send positioning reference signal.

[0763] That is, after receiving the second signal, it is awakened or partially awakened, or sends / receives a specific reference signal, SSB, measures CSI-RS or synchronization signal, etc.

[0764] Here, partial awakening means that the base station only sends and / or receives part of the reference signals, or switches to parameter configuration in the energy-saving state, etc. For details, please refer to the fourth embodiment.

[0765] In the embodiment of the present disclosure, the above-mentioned OOK / ASK / FSK / PSK signal is a low-power signal different from the OFDM signal. The processing method of the low-power signal is different from the processing method of the OFDM signal in the related technology. The cell in the sleep state or the energy-saving state can process the low-power signal, so that the terminal can communicate with the sleep cell or the cell in the energy-saving state without synchronization through the low-power signal, thereby achieving the purpose of waking up the sleep cell or triggering the sleep cell to wake up and provide services.

[0766] As shown in FIG18 , an embodiment of the present disclosure further provides a signal transmission method, which is performed by a network-side device. The method includes:

[0767] Step 1801: Receive an uplink signal, where the uplink signal carries at least one of discovery information and trigger information;

[0768] The discovery information is used to discover the terminal; and the trigger information is used for at least one of the following:

[0769] Wake up the target cell;

[0770] triggering the target cell to send and / or receive a first object, where the first object includes at least one of a first reference signal and a first channel;

[0771] Trigger the target cell to switch to the target cell state.

[0772] In some embodiments, the target cell includes at least one of a dormant cell, a closed cell, a sleeping cell, and a power-saving cell. The target cell may be a primary serving cell or a secondary cell, and the target cell has a cell identifier ID.

[0773] In some embodiments, the above-mentioned first reference signal includes at least one of the following: primary synchronization signal (PSS), secondary synchronization signal (SSS), synchronization signal / physical broadcast channel signal block (Synchronization Signal Block, SSB), tracking reference signal (CSI Reference Signal for Tracking, TRS), positioning reference signal (Positioning Reference Signal, PRS), phase tracking reference signal (Phase-tracking reference signal, PT-RS), random access preamble code, sounding reference signal (SRS), demodulation reference signal (DMRS), CSI reference signal (CSI Reference Signal, CSI-RS).

[0774] In some embodiments, the first channel includes at least one of the following: physical uplink control channel (PUCCH), physical downlink control channel (PDCCH), physical broadcast channel (PBCH), physical random access channel (PRACH), physical sidelink shared channel (PSSCH), physical downlink shared channel (PDSCH), and physical uplink shared channel (PUSCH). The above-mentioned first object is defined by the protocol or pre-configured by high-layer signaling.

[0775] In an embodiment of the present disclosure, an uplink signal is received, the uplink signal carrying at least one of discovery information and trigger information; wherein the discovery information is used to discover a terminal; the trigger information is used to at least one of the following: wake up a target cell; trigger the target cell to send and / or receive a first object, the first object including at least one of a first reference signal and a first channel; trigger the target cell to switch to a first state. Thus, the above-mentioned discovery information and / or trigger information can be used to wake up a dormant cell or trigger a dormant cell to wake up and provide services.

[0776] In some embodiments, the uplink signal includes a modulation signal, and the modulation signal includes at least one of an on-off keying (OOK) modulation signal, an amplitude-shifted keying (ASK) modulation signal, a frequency-shifted keying (FSK) modulation signal, and a phase-shifted keying (PSK) modulation signal.

[0777] The above-mentioned OOK / ASK / FSK / PSK signal is a low-power signal different from the OFDM signal. The processing method of the low-power signal is different from the processing method of the OFDM signal in the related technology. The cell in the sleep state or energy-saving state can process the low-power signal, so that the terminal can communicate with the sleep cell or the cell in the energy-saving state without synchronization through the low-power signal, thereby achieving the purpose of waking up the sleep cell or triggering the sleep cell to wake up and provide services.

[0778] In some embodiments, the modulated signal is an Orthogonal Frequency Division Multiplexing (OFDM) based signal.

[0779] When the above-mentioned modulated signal is an OFDM-based OOK / ASK / FSK / PSK signal, the architecture of the NR transceiver in the related technology can be utilized to further avoid adding a new transceiver, thereby simplifying the complexity of the transceiver. Signal detection based on OOK / ASK / FSK / PSK modulation can greatly reduce the power consumption of the receiving end because it does not require an inverse Fourier transform (IFFT) operation to perform envelope, filtering or phase detection, thereby achieving energy saving.

[0780] In some embodiments, the uplink signal includes an OFDM-based reference signal or channel.

[0781] The OFDM-based reference signal or channel is an OFDM-based reference signal or channel in NR, such as a reference signal that is at least one of PSS, SSS, SSB, TRS, PRS, PT-RS, random access preamble, SRS, DMRS, and CSI-RS, and an OFDM-based channel in NR that is at least one of PUCCH, PDCCH, PBCH, PRACH, PSSCH, PDSCH, and PUSCH.

[0796] In this implementation, the first trigger information and the second trigger information are complementary trigger information or at least partially overlapping trigger information. For example, the fourth uplink signal is used to discover the terminal and trigger the target cell to send and / or receive the first object, and the fifth uplink signal is used to wake up the target cell or trigger the target cell to switch to the target cell state. The fourth uplink signal is a modulated signal based on OOK / ASK / FSK / PSK, and the fifth uplink signal is a modulated signal based on OOK / ASK / FSK / PSK, or a reference signal based on OFDM.
