Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a signal transmission method and apparatus. Background Art

[0002] Network energy conservation is very important for environmental sustainability, reducing environmental impact (greenhouse gas emissions), and saving operating costs.

[0208] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, rather than all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0212] Figure 1 The block diagram of a wireless communication system to which the embodiments of the present application can be applied is shown. The wireless communication system includes a terminal device 11 and a network-side device (or network device) 12. Among them, the terminal device 11 can also be referred to as a terminal or a user terminal (User Equipment, UE). It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present application. The network-side device 12 can be a base station or a core network. It should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0213] As Figure 2 shown, the embodiments of the present application provide a signal transmission method, which is executed by a terminal. The method includes:

[0214] Step 201: Transmit an uplink signal, where the uplink signal carries at least one of discovery information and trigger information;

[0215] Among them, the discovery information is used to discover the terminal; the trigger information is used for at least one of the following:

[0216] Wake up the target cell;

[0217] Trigger 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;

[0218] Trigger the target cell to switch to a target cell state. For example, the target cell state includes a light sleep state.

[0219] Optionally, the above target cell includes at least one of a cell in a dormant state, a cell in a closed state, a cell in a sleep state, and a cell in an energy-saving state. The target cell may be a primary serving cell or a secondary cell, and the target cell has a cell identification ID.

[0220] Optionally, the above first reference signal includes at least one of the following: Primary Synchronisation Signal (PSS), Secondary Synchronisation Signal (SSS), Synchronization Signal Block (SSB), CSI Reference Signal for Tracking (TRS), Positioning Reference Signal (PRS), Phase-tracking reference signal (PT-RS), random access preamble, Sounding Reference Signal (SRS), Demodulation Reference Signal (DMRS), CSI Reference Signal (CSI-RS).

[0221] Optionally, 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), Physical Uplink Shared Channel (PUSCH).

[0222] The above first object is defined by the protocol or pre-configured by the high-layer signaling.

[0223] In an embodiment of the present application, an uplink signal is sent, and the uplink signal carries at least one of discovery information and trigger information; the discovery information is used to discover a terminal; the trigger information is used for at least one of the following: waking up a target cell; 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; triggering the target cell to switch to a target cell state. Thus, through the above discovery information and / or trigger information, the purpose of waking up a dormant cell or triggering a dormant cell to wake up to provide services can be achieved.

[0224] Optionally, the uplink signal at least 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.

[0225] Optionally, the above terminal includes a terminal to be served, which can be an exclusive 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 can be based on a multi-carrier waveform, such as CP-OFDM, or can be based on a single-carrier waveform, such as DFT-S-OFDM.

[0226] The above OOK / ASK / FSK / PSK signals are low-power signals different from OFDM signals, and the processing method of this low-power signal is different from the processing method of existing OFDM signals. A cell in a dormant state or an energy-saving state can process this low-power signal, so that through this low-power signal, the terminal can communicate with a dormant cell or a cell in an energy-saving state without synchronization, and further achieve the purpose of waking up a dormant cell or triggering a dormant cell to wake up to provide services.

[0227] Optionally, the modulation signal is an Orthogonal Frequency Division Multiplexing (OFDM)-based signal.

[0228] When the above modulation signal is an OFDM-based OOK / ASK / FSK / PSK signal, the architecture of the existing NR transceiver can be utilized to further avoid adding a new transceiver, thereby simplifying the complexity of the transceiver. For the signal detection based on OOK / ASK / FSK / PSK modulation, since it does not require an inverse fast Fourier transform (IFFT) operation but performs envelope, filtering, or phase detection, the power consumption at the receiving end can be greatly reduced, thus achieving the effect of energy saving.

[0229] Optionally, the uplink signal further includes an OFDM-based reference signal or channel.

[0230] The OFDM-based reference signal or channel is the OFDM-based reference signal or channel in NR. For example, the reference signal is at least one of PSS, SSS, SSB, TRS, PRS, PT-RS, random access preamble, SRS, DMRS, CSI-RS, etc. The OFDM-based channels in NR are at least one of PUCCH, PDCCH, PBCH, PRACH, PSSCH, PDSCH, PUSCH, etc.

[0231] Optionally, the discovery information includes at least one of the amplitude, frequency point, carrier, bandwidth, phase, power, and energy of the signal for signal detection.

[0232] This discovery information is used for a cell or base station (such as a Pico) around the terminal to discover the terminal.

[0233] Optionally, the trigger information includes at least one of the following:

[0234] The first indication information, which is the indication information for waking up the target cell;

[0235] The second indication information, which is the indication information for triggering the target cell to receive and / or transmit the first object. The first object includes at least one of the first reference signal and the first channel;

[0236] The third indication information, which is the indication information for triggering the target cell to switch to the target cell state;

[0237] Fourth indication information, where the fourth indication information is used to indicate the identification information of the target cell; for example, when the above trigger information only includes the fourth indication information, by means of protocol agreement or base station pre-configuration, it is determined that the target cell indicated by the fourth indication information is the target cell that needs to be woken up, the cell that needs to send and / or receive the first object, and / or the cell that needs to switch to the target cell state. After receiving the fourth indication information, if the identification of the cell is consistent with the identification indicated by the fourth indication information, the network-side device enters the wake-up state, sends and / or receives the first object, and / or switches to the target cell state.

[0238] Fifth indication information, where the fifth indication information is used to trigger the target cell to turn on and / or off a specific function;

[0239] Sixth indication information, where the sixth indication information is used to indicate the specific identification of the terminal;

[0240] Seventh indication information, where the seventh indication information is used to indicate the demand information of the terminal.

[0241] Optionally, at least one of the indication information in the trigger information is indicated in an explicit or implicit manner.

[0242] As an implementation manner, the implicit indication manner may be that the protocol agreement or base station pre-configuration indicates at least one of the above indication information, or implicitly indicates at least one of the above indication information through a specific sequence of the uplink signal.

[0243] Exemplarily, the above uplink signal includes a discovery signal carrying discovery information, and the discovery signal may carry at least one of the above indication information by means of protocol agreement or base station pre-configuration. For example, it carries the first indication information and / or the second indication information. For example, it may be made by protocol agreement or base station pre-configuration that different sequences of the discovery signal implicitly indicate different indication information.

[0244] As an implementation manner, the above uplink signal includes a trigger signal carrying trigger information, and the explicit indication manner may be indicated through the information field of the trigger signal. For example, there is a dedicated information field corresponding to each indication information in the trigger signal, or at least one of the above indication information may be jointly indicated through one information field. The information field may be, in addition to the information field in the trigger signal, a sequence of a specific length.

[0245] For example, the protocol agreement or base station pre-configuration implicitly indicates at least one of the above indication information through the discovery information, or implicitly indicates at least one of the above indication information through a specific sequence of the trigger signal.

[0246] Optionally, the trigger information includes N-bit information, where N is an integer greater than or equal to 0;

[0247] The N-bit information of the trigger information is used to indicate M pieces of indication information in the trigger information. The i-th piece of indication information among the M pieces of indication information corresponds to K i bits in the N bits, and different indication information corresponds to different bits in the N bits. M is an integer greater than or equal to 1 and less than or equal to N, and K i is less than or equal to N, and K i is greater than or equal to 0; and / or, the value or pattern corresponding to N1 bits in the N-bit information of the trigger information is used to indicate at least one piece of indication information in the trigger information, where N1 is an integer greater than or equal to 1 and less than or equal to N.

[0248] For example, when M = N and K i = 1, that is, N pieces of indication information are indicated by N-bit information, and each piece of indication information corresponds to one bit, that is, the above indication information is indicated by means of bit mapping, that is, each piece of indication information is indicated by a single bit.

[0249] Another example, when M is different from N, N bits indicate M pieces of indication information. The i-th piece of indication information among the M pieces of indication information corresponds to K i bits in the N bits, 1 ≤ i ≤ M, and K 1 + K 2 +... + ≤ N. For example, when M is 3 and N is 8, the first piece of indication information corresponds to the first bit and the second bit, the second piece of indication information corresponds to the third bit and the fourth bit, and the third piece of indication information corresponds to the fifth bit and the sixth bit. Another example, the first piece of indication information corresponds to the first bit, the second piece of indication information corresponds to the second bit and the third bit, and the third piece of indication information corresponds to the fourth bit to the eighth bit.

[0250] Another example, as defined by the protocol, when the terminal does not send a trigger signal, the trigger information is default, that is, N = 0.

[0251] Optionally, among the N-bit information of the trigger information, it includes: an information function indication field and an indication information field, where the information function indication field can indicate the specific content of the indication information field by bit mapping or value or specific pattern.

[0252] For example: The information function indication field has 3-bit information, corresponding to the first indication information, the second indication information, and the third indication information respectively. Assuming that the second bit information corresponds to "1", the subsequent indication information field is the second indication information.

[0253] For another example: The information function indication field has 2-bit information. The 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.

[0254] For another example: The information function indication field has an N-bit sequence of M patterns, and different patterns respectively correspond to different indication information. According to the bit sequence pattern of the information function indication field, it can be known which indication information the subsequent indication information field specifically indicates.

[0255] Optionally, the first indication information includes at least one of the indication information on whether to wake up the target cell and the indication information on the target cell to be woken up;

[0256] 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 target cell to be woken up, where A1 is an integer greater than or equal to 0.

[0257] In the embodiment of the present application, the uplink signal may include the 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, the wake-up indication for at least one target cell or target cell group is performed by means of 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.

[0258] 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 pattern. The terminal sends the A1-bit sequence at the resource position pre-configured or agreed upon by the protocol. The specific pattern of the A1-bit sequence can be pre-stored or pre-configured. After receiving the A1-bit sequence of the specific pattern, if its specific pattern is consistent with the pre-stored or pre-configured pattern sequence, it is considered that the indication cell is woken up; otherwise, it is indicated that the cell is not woken up.

[0259] For another example, when the value corresponding to the A1-bit information corresponding to the first indication information is the first value, it indicates waking up the cell, and when the value corresponding to the A1-bit information corresponding to the first indication information is the first value, it indicates not waking up the cell.

[0260] For another example, the wake-up indication of the target cell is performed by whether the first indication information is included, that is: sending the first indication information wakes up the target cell or cell group, A1 is greater than or equal to 1; not sending the first indication information does not wake up the target cell or cell group, A1 is equal to 0.

[0261] Optionally, the second indication information includes at least one of indication information on whether to send and / or receive a first object, and indication information on sending and / or receiving the first object;

[0262] 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 a first object, and at least one of sending and / or receiving the first object through A3 bits among the A2 bits, or indicates whether to send and / or receive a first object, and at least one of sending and / or receiving the first object through a 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;

[0263] And / or, when A3 is greater than 1, the A3 bits indicate whether to send and / or receive a first object, and at least one of sending and / or receiving the first object in a bit mapping manner. For example, each of the A3 bits corresponds to a different first object.

[0264] In the embodiments of the present application, the A3 corresponding to different indication information in the second indication information is the same or different.

[0265] For example, when A2 = 5, the first bit among the 5 bits indicates a first reference signal, and the second bit among the 5 bits indicates a second reference signal. When the value corresponding to the first bit is 1, it means to send and / or receive the first reference signal, and when the value corresponding to the first bit is 0, it means not to send and / or not to receive the first reference signal. When the value corresponding to the second bit is 1, it means to send and / or receive the second reference signal, and when the value corresponding to the second bit is 0, it means not to send and / or not to receive the second reference signal.

[0266] For another example, when A2 = 5, the first to second bits among the 5 bits indicate a first reference signal, and the third to fifth bits among the 5 bits indicate a second reference signal. The corresponding value or pattern of the first to second bits is used to indicate the corresponding parameter configuration of the first reference signal. For example, "00" indicates to send and / or receive according to the first parameter configuration of the first reference signal, "01" indicates to send and / or receive according to the second parameter configuration of the first reference signal, etc. The corresponding value or pattern of the third to fifth bits is used to indicate the corresponding parameter configuration of the second reference signal. For example, "001" indicates to send and / or receive according to the first parameter configuration of the second reference signal, "010" indicates to send and / or receive according to the second parameter configuration of the second reference signal, etc.

[0267] For another example, different sequences or different values corresponding to A2 bits are used to indicate different first objects. For example, when the A2 bits correspond to the value 1 or the sequence 1, they are used to indicate the transmission and / or reception of a first reference signal and a second reference signal. When the A2 bits correspond to the value 2 or the sequence 2, they are used to indicate the transmission and / or reception of a third reference signal and a fourth reference signal.

[0268] For another example, it is indicated whether to transmit and / or receive a first object by whether the second indication information is included, that is: transmitting the second indication information indicates transmitting and / or receiving the first object, where A2 is greater than or equal to 1; not transmitting the second indication information indicates not transmitting and / or not receiving the first object, and A2 is equal to 0.

[0269] Optionally, the third indication information includes at least one of indication information indicating whether the target cell switches between at least one state, and indication information for switching to or maintaining the state of the target cell;

[0270] 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 whether to switch between at least one state, switch to or maintain the state of the target cell, etc. through A5 bits among the A4 bits, or indicates whether to switch between at least one state, switch to or maintain the state of the target cell, etc. through the sequence and / or value corresponding to the A4 bits; A5 is less than or equal to A4, and A5 is an integer greater than or equal to 0;

[0271] And / or, when A5 is greater than 1, the A5 bits indicate whether to switch between at least one state, switch to or maintain the state of the target cell, etc. in a bit mapping manner. For example, each of the A5 bits corresponds to a different target cell state.

[0272] In the embodiments of the present application, the A5 corresponding to different indication information in the third indication information is the same or different.

[0273] For example, A4 = 5. The first of the 5 bits indicates the first energy-saving state, and the second of the 5 bits indicates the second energy-saving state. When the value corresponding to the first bit is 1, it means switching to the first energy-saving state. When the value corresponding to the first bit is 0, it means not switching to the first energy-saving state. When the value corresponding to the second bit is 1, it means switching to the second energy-saving state. When the value corresponding to the second bit is 0, it means not switching to the second energy-saving state.

[0274] For another example, different sequences or different values corresponding to 4 bits of A are used to indicate different target cell states. For example, when the 4 bits of A correspond to the value 1 or the sequence 1, it is used to indicate the first target cell state; when the 4 bits of A correspond to the value 2 or the sequence 2, it is used to indicate the second target cell state.

[0275] For another example, it is indicated whether to switch between at least one state by whether to contain the third indication information, 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.

[0276] Optionally, 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.

[0277] For example, the first information field has 3-bit 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.

[0278] For another example, the first information field has 2-bit information, and its values of "01" correspond to cell state 1, "10" correspond to cell state 2, and "11" correspond 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.

[0279] For another example: the first information field has an N-bit sequence of M patterns, and different patterns respectively correspond to different cell states. According to the bit sequence pattern of the first information field, the cell state corresponding to the subsequent second information field can be obtained.

[0280] In the embodiments of the present application, the specific reference signal and / or channel in different cell states can be configured through at least one of high-layer signaling configuration, core network signaling configuration, terminal pre-storage, neighboring cell signaling notification, etc.

[0281] Optionally, the fourth indication information includes at least one of an index in the frequency list of the cell, an index in the cell list, a cell identifier, a cell ID, and a bit mapping of at least one cell.

[0282] For example, the modulation patterns of different OOK / ASK / FSK / PSK modulation signals correspond to the index values of the cell ID or the cell list in different cells or cell groups.

[0283] For another example, the fourth indication information is used in combination with other indication information. For example, there are N bit information in the trigger information, which can be divided into M information groups. Each information group corresponds to a target cell or a target cell group. Each information group includes Ki bit 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 an individual indication or a combined indication.

[0284] Optionally, the fifth indication information includes indication information on whether to enable and / or disable a specific function, and at least one of the indication information on enabling and / or disabling at least one specific function;

[0285] 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 enable and / or disable a specific function, and at least one of the indication information on enabling and / or disabling at least one specific function through A7 bits among the A6 bits, or indicates whether to enable and / or disable a specific function, and at least one of the indication information on enabling and / or disabling at least one specific function through the sequence and / or value corresponding to the A6 bits. A7 is less than or equal to A6, and A7 is an integer greater than or equal to 0;

[0286] And / or, when A7 is greater than 1, the A7 bits indicate whether to enable and / or disable a specific function, and at least one of the indication information on enabling and / or disabling at least one specific function in a bit mapping manner. For example, each of the A7 bits corresponds to a different specific function;

[0287] The above specific functions include at least one of the following: access function, measurement function, synchronization function, positioning function, energy saving function, 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;

[0288] In the embodiments of the present application, the A7 corresponding to different indication information in the fifth indication information is the same or different.

[0289] For example, A6 = 5. The first of the 5 bits indicates the first specific function, and the second of the 5 bits indicates the second specific function. When the value corresponding to the first bit is 1, it indicates enabling the first specific function, and when the value corresponding to the first bit is 0, it indicates disabling the first specific function. When the value corresponding to the second bit is 1, it indicates enabling the second specific function, and when the value corresponding to the second bit is 0, it indicates disabling the second specific function.

[0290] For another example, different sequences or different values corresponding to 6 bits of A are used to indicate different specific functions. For example, when the 6 bits of A correspond to the value 1 or the sequence 1, it is used to indicate the first specific function, and when the 6 bits of A correspond to the value 2 or the sequence 2, it is used to indicate the second specific function.

[0291] For another example, whether to enable and / or disable a specific function is indicated by whether the fifth indication information is included, that is: sending the fifth indication information indicates enabling the specific function, A6 is greater than or equal to 1; not sending the fifth indication information indicates disabling the specific function, A6 is equal to 0.

[0292] Optionally, the fifth indication information includes a third information field and a fourth information field. The third information field is used to indicate a specific function, and the fourth information field is used to indicate the reference signal and / or channel corresponding to the specific function. For example, the third information field has 3 bits of information, corresponding to specific function 1, specific function 2, and specific function 3 respectively. Assuming that the second bit of information is 1, the fourth information field is used to indicate the reference signal and / or channel corresponding to specific function 2.

[0293] For another example, the third information field has 2 bits of information, and its values of "01" correspond to specific function 1, "10" correspond to specific function 2, and "11" correspond to specific function 3. Assuming that the value of the third information field is "10", the fourth information field is used to indicate the reference signal and / or channel corresponding to specific function 2.

[0294] For another example: the third information field has an N-bit sequence of M patterns, and different patterns respectively correspond to different specific functions. According to the bit sequence pattern of the third information field, the specific function corresponding to the subsequent fourth information field can be obtained.

[0295] Optionally, the sixth indication information includes at least one of a specific type of the terminal and terminal identification information;

[0296] And / or, the sixth indication information includes 8 bits of A, A8 is an integer greater than or equal to 0. The sixth indication information indicates at least one of a specific type of the terminal and terminal identification information through A9 bits among the 8 bits of A, or indicates at least one of a specific type of the terminal and terminal identification information through the sequence and / or value corresponding to the 8 bits of A. A9 is less than or equal to A8, and A9 is an integer greater than or equal to 0;

[0297] And / or, when A9 is greater than 1, the A9 bits indicate at least one of a specific type of the terminal and terminal identification information in a bit mapping manner. For example, each of the A9 bits corresponds to a different specific type of the terminal or terminal identification;

[0298] Optionally, the terminal identification information includes at least one of the following: terminal type identification, terminal version identification, terminal identification for supporting specific services, such as significant identification for supporting latency-sensitive services (such as XR services), and terminal identification for exclusive services of dormant base stations.

[0299] In the embodiments of the present application, the A7s corresponding to different indication information in the sixth indication information are the same or different.

[0300] For example, A8 = 4. The first bit among the 4 bits is used to indicate the first specific type, the second bit among the 4 bits is used to indicate the second specific type, and the third bit among the 4 bits is used to indicate the first terminal identification.

[0301] For another example, different sequences or different values corresponding to A8 bits are used to indicate different specific types or terminal identifications. For example, when the A8 bits correspond to the value 1 or sequence 1, they are used to indicate the first specific type or the first terminal identification, and when the A8 bits correspond to the value 2 or sequence 2, they are used to indicate the second specific type or the second terminal identification.

[0302] Optionally, the sixth indication information includes a fifth information field and a sixth information field. The fifth information field is used to indicate the specific type and / or terminal identification of the terminal, and the sixth information field is used to indicate the reference signal and / or channel corresponding to the specific type and / or terminal identification.

[0303] For example, the fifth information field has 3 bits of information, corresponding to specific type 1 and / or terminal identification 1, specific type 2 and / or terminal identification 2, and specific type 3 and / or terminal identification 3 respectively. Assuming that the second bit of information is 1, the sixth information field is used to indicate the reference signal and / or channel corresponding to specific type 2 and / or terminal identification 2.

Assuming that the value of the fifth information field is "10", the sixth information field is used to indicate the reference signal and / or channel corresponding to specific type 2 and / or terminal identification 2.

[0305] For another example: The fifth information field has an N-bit sequence of M patterns, and different patterns respectively correspond to different specific types and / or terminal identifications. According to the bit sequence pattern of the fifth information field, the specific type and / or terminal identification corresponding to the subsequent sixth information field can be obtained.

[0307] And / or, the seventh indication information includes A10 bits, where A10 is an integer greater than or equal to 0.

[0311] In the embodiments of the present application, the A11 corresponding to different indication information in the seventh indication information is the same or different.

[0312] For example, A10 = 5. The first bit among the 5 bits indicates the access requirement, the second bit among the 5 bits indicates the positioning requirement, the third bit among the 5 bits indicates the URLLC service, and the fourth bit among the 5 bits indicates the mMTC service.

[0313] For another example, different sequences or different values corresponding to the A10 bits are used to indicate different service requirements or service types. For example, when the A10 bits correspond to the value 1 or the sequence 1, they are used to indicate the first service requirement or the first service type, and when the A10 bits correspond to the value 2 or the sequence 2, they are used to indicate the second service requirement or the second service type.

[0314] Optionally, the seventh indication information includes a seventh information field and an eighth information field. The seventh information field is used to indicate the service requirement and / or service type of the terminal, and the eighth information field is used to indicate the reference signal and / or channel corresponding to the service requirement and / or service type. For example, the seventh information field has 3-bit information, corresponding to service requirement 1 and / or service type 1, service requirement 2 and / or service type 2, and service requirement 3 and / or service type 3 respectively. Assuming that the second bit of information is 1, the eighth information field is used to indicate the reference signal and / or channel corresponding to service requirement 2 and / or service type 2.

[0327] Optionally, the method of the embodiments of the present application further includes:

[0328] Obtain resource-related information of the uplink signal, where the resource-related information is used to generate the uplink signal and / or to determine the transmission resource location of the uplink signal;

[0329] Among them, 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 high-layer signaling of the neighboring cell, 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.

[0330] Optionally, the resource-related information of the uplink signal includes at least one of the following:

[0331] Generation-related information of the uplink signal;

[0332] Resource location information of the uplink signal;

[0333] Among them, the generation-related information includes at least one of the transmission frequency point, 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;

[0334] The resource location information includes at least one of time domain resource location information, frequency domain resource location information, and spatial domain resource location information.

[0335] Optionally, the time domain resource location information includes at least one of the following: the time domain location information of the uplink signal; the association information with the time domain location of a specific signal / channel; the duration of the uplink signal transmission; the effective time of the uplink signal transmission; the effective time interval of the uplink signal transmission; the uplink signal transmission pattern within a specific time period; the number of times of the uplink signal transmission; the period of the uplink signal transmission.

[0336] In the embodiments of the present application, the time domain resources of the uplink signal can be periodic, semi-persistent, or transmitted in a certain pattern within a transmission time window, or have an association relationship with a specific signal or a specific channel. The above specific signals include at least one of PSS, SSS, SSB, SIB1, TRS, PRS, PT-RS, random access preamble, SRS, DMRS, CSI-RS, etc. The specific channels include at least one of PUCCH, PDCCH, PBCH, PRACH, PSSCH, PDSCH, PUSCH, etc.

[0337] For example, the time-domain resource location of the uplink signal can be sent periodically or semi-persistently. The base station can continuously detect the uplink signal or detect it based on a detection window, specifically depending on the base station implementation. The detection window can also be periodic or triggered based on timing. The transmission period of the uplink signal can be a default period, such as defined by the protocol, or consistent with the default period of a specific reference signal, such as the default period of 20 ms for the SSB.

[0338] When the uplink signal is sent semi-persistently, it can start being sent when the terminal needs to wake up or trigger a specific cell to provide services for it. The transmission time of the uplink signal can be sent based on the System Frame Number (SFN).

[0339] For another example: The uplink signal is sent within a specific time window. This 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 this time window (as shown in Figure 6 ). For another example: There is an association relationship 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 a 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 may be a value less than or equal to 0 (as shown in Figure 9 ).

[0340] Optionally, there is an association relationship between the discovery information and the trigger information. For example, the transmission period of the trigger information is S times or 1 / S of the transmission period of the discovery information, where S is a positive integer. Or, when the two pieces of information are carried by the same signal, the discovery information occupies M1 time slot symbols and the trigger information occupies M2 time slot symbols. Or, 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. Or, 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 the time unit corresponding to the bit information.

[0341] Optionally, the frequency-domain resource information of the uplink signal includes at least one of the following: the subcarriers where the uplink signal is located; the bandwidth part BWP or frequency point where the uplink signal is located, for example, the exclusive frequency point or exclusive BWP where the uplink signal is located; the transmission pattern of the uplink signal in the frequency domain.

[0342] For example, a specific BWP corresponding to a specific carrier frequency can be used for uplink signal transmission. There are N subcarriers in this BWP, and the uplink signal can occupy M subcarriers among them, where M is an integer less than or equal to N. The M carriers can be the M subcarriers with the smallest sequence numbers among the N subcarriers, or the M subcarriers with the largest sequence numbers, or M random subcarriers, or M subcarriers with a specific pattern. The specific pattern can be obtained in at least one of the following ways: configured by the base station, pre-configured by the terminal, pre-stored by the terminal, obtained according to the terminal ID or cell ID or generation sequence related parameters, generated according to scrambling codes or pseudo-random sequences, etc.

[0343] Optionally, the spatial domain resource position information of the uplink signal includes beam-related information of the uplink signal. For example, omnidirectional antenna transmission and / or specific beam direction transmission.

[0344] For example: when the uplink signal carries discovery information, it can be transmitted through an omnidirectional antenna, or the uplink signal can be transmitted in a time-division manner in different beam directions. When the terminal receives the response signal corresponding to the corresponding beam, it can determine the target cell.

[0345] Another example: when the terminal can obtain coarse synchronization or receives the response signal sent by the target cell, it can also send the uplink signal carrying discovery information and / or trigger information on a specific beam based on the coarse synchronization and / or the response signal.

[0346] Optionally, the method of the embodiment of the present application further includes:

[0347] Obtain the response signal of the uplink signal;

[0348] Wherein, the response signal carries at least one of the following:

[0349] Confirmation information for the uplink signal;

[0350] Feedback information for the uplink signal;

[0351] A second reference signal and / or a second channel, where the second reference signal is a reference signal for subsequent determination of whether the terminal wakes up a dormant cell or a reference signal for providing a specific function for the terminal. For example, the specific function can be functions such as synchronization, measurement, or positioning;

[0352] Cell information of the cell sending the response signal;

[0353] Specific cell information.

[0354] Optionally, the above second reference signal includes at least one of the following: PSS, SSS, SSB, TRS, PRS, PT-RS, SRS, DMRS, CSI-RS.

[0355] Optionally, the second channel includes at least one of the following: PUCCH, PDCCH, PBCH, PRACH, PSSCH, PDSCH, PUSCH.

[0356] In the embodiments of the present application, the uplink signal may include at least one uplink signal, and the above response signal includes a response signal indicating the at least one uplink signal. The at least one uplink signal may be sent simultaneously or in a certain order.

[0357] For example, the above 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. The second signal carries trigger information, or carries discovery information and trigger information. That is, the first signal and the second signal may be the same, such as both carrying discovery information and trigger information, or they may be different, such as the first signal carrying discovery information and the second signal carrying trigger information. And the signal types of the first signal and the second signal may be the same or different. For example, the first signal is a modulation signal based on OOK / ASK / FSK / PSK, and the second signal is an uplink control signaling or uplink reference signal based on NR.

[0358] The terminal sends the 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, etc. 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 may be a modulation signal based on OOK / ASK / FSK / PSK, or a specific reference signal. Then the terminal sends the second signal. The second signal may be sent after a specific time interval after receiving the response signal of the first signal sent by the cell, or may be sent at a specific time interval from the sending time of the first signal. The trigger information carried by the first signal or the second signal may be obtained through one or several of the following methods: neighbor cell high-layer signaling configuration, core network signaling configuration, broadcast signaling sending, protocol definition, etc.

[0359] 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, or sends a response signal or receives the second signal, it is woken up or triggered to send / receive a specific reference signal, or switches to the target cell state according to the corresponding signal and / or the information carried by it.

[0360] Optionally, there is a certain time offset between the first signal and the second signal, and the time offset may be determined based on at least one of the following: a specific timer, high-layer signaling pre-configuration, protocol definition, terminal pre-storage, etc.

[0361] In the embodiments of the present application, the network-side device may perform the first signal detection in the following manner.

[0362] When the base station detects the first signal, it obtains one of the relevant information such as its amplitude / phase / power / energy, etc. For example, it obtains that the power value of its signal is P, or obtains that the amplitude value of its signal is A, or obtains that the energy value of its signal is E, or obtains that the phase information of its signal is θ. Assume 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.

[0363] Assume that the specific condition is greater than the amplitude threshold A0. If the base station detects that the amplitude value A of the first signal is greater than the amplitude threshold A0, it 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.

[0364] Assume that the specific condition is greater than the energy threshold E0. If the base station detects that the energy value E of the first signal is greater than the energy threshold E0, it 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.

[0365] Assume that the specific condition is within the phase value range {Θmax, Θmin}. If the base station detects that the phase value θ of the first signal is within the phase value range, it 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. For example: when the terminal sends the first signal, it can perform different phase modulations on base stations in different directions. {0, π} is a cell in one direction, and {π, 2π} is a cell in one direction. The base station performs coherent demodulation on the received signal to obtain the value range where the phase of the first signal is located.

[0366] Assume that the specific condition is that the indication information carried by the first signal is a specific value. For example, all N bits are 1. If the base station detects that the indication information carried by the first signal meets the specific value, it 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.

[0367] When the base station determines that the current terminal falls within the service range of the base station, the sleeping cell is awakened and sends an SSB signal, or a CSI-RS or a reference signal for positioning to provide conventional services for the terminal; otherwise, the sleeping cell will not be awakened.

[0368] In the embodiments of the present application, when the terminal sends a first signal, the terminal may further send a second signal, which can further provide additional information for the base station. The additional information includes at least one of the following: enhancement or supplementary information of the first signal, that is, information for improving the reception performance of the first signal, or supplementary information of the first signal.

[0369] For the information of the second signal used to improve the reception performance of the first signal, for example: the second signal is a repeated signal of the first signal, or the second signal carries information related to the first signal, but the first signal and the second signal are two different signals. The terminal sending the second signal can improve the performance of the base station in discovering the terminal and obtaining the information carried by the first signal and / or the second signal.

[0370] For the information of the second signal used to provide supplementary information of the first signal, for example: the first signal is sent by broadcast when the terminal and the base station are not synchronized or not precisely synchronized, and is used as a signal for the base station to discover the terminal. The second signal can be sent as supplementary information of the terminal, such as: the version or type of the terminal, so that the target cell that can serve the terminal can be discovered. After the base station detects the first signal, it detects the second signal. If the cell can serve the terminal, the cell is woken up as the target cell and is triggered to send or receive a second object; at least one of triggering a switch to a second state is performed. In this way, by sending the second signal, the accuracy of waking up or triggering the target cell can be improved, and the network energy-saving performance can be improved.

[0371] Optionally, the method of the embodiments of the present application further includes:

[0372] At a first moment, sending and / or receiving a second object of a target cell;

[0373] Wherein, the first moment includes at least one of the following:

[0374] A moment separated from the sending moment of the uplink signal by a first time period;

[0375] A moment separated from the receiving moment of the response signal of the uplink signal by a second time period;

[0376] Wherein, the target cell includes at least one of the following:

[0377] At least one cell indicated by the trigger information;

[0378] At least one cell that sends the response signal;

[0379] At least one cell indicated by the response signal;

[0380] The cell accessed by the terminal;

[0381] Wherein, the second object includes at least one of the following:

[0382] The synchronization signal / physical broadcast channel signal block SSB or system information block SIB1 sent by the target cell;

[0383] At least one of the reference signals and channels sent by the target cell;

[0384] At least one of the first reference signal and the first channel indicated by the trigger information;

[0385] At least one of the reference signal and the channel corresponding to the specific function indicated by the trigger information;

[0386] At least one of the reference signal and the channel corresponding to the demand information of the terminal indicated by the trigger information;

[0387] At least one of the reference signal and the channel corresponding to the target cell state indicated by the trigger information;

[0388] At least one of the reference signal and the channel under the default parameter configuration;

[0389] At least one of the reference signal and the channel under the parameter configuration carried by the broadcast channel or broadcast message of the access cell;

[0390] The second reference signal and / or the second channel indicated by the response signal.

[0391] The above 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 channels include at least one of PUCCH, PDCCH, PBCH, PRACH, PSSCH, PDSCH, PUSCH, etc.

[0392] In the embodiments of the present application, an uplink signal is sent, and the uplink signal carries at least one of discovery information and trigger information; the discovery information is used to discover the terminal; the trigger information is used for at least one of the following: waking up the target cell; triggering the target cell to send and / or receive a first object, where the first object includes at least one of the first reference signal and the first channel; triggering the target cell to switch to the target cell state. Thus, through the above discovery information and / or trigger information, the purpose of waking up a dormant cell or triggering a dormant cell to wake up to provide services can be achieved.

[0393] The solution of the present application will be described in detail below in conjunction with embodiments.

[0394] Embodiment 1: The structure of the transceiver of the uplink signal (illustrated by taking the above first signal and / or second signal as an example);

[0395] As Figure 3 And Figure 4As shown, the transmitter for the terminal to send the above first signal and / or second signal can be an independent transmitter from the transmitter for the uplink NR signal, or can be the same transmitter.

[0396] The receiver for the base station to receive the first signal and / or second signal can be an independent receiver from the receiver for the uplink NR signal, or can be the same receiver.

[0397] When the first signal and / or second signal includes signals with different functions, the transceivers for different signals are different. For example:

[0398] The first signal (carrying discovery information for discovering the terminal, which can also be described as a discovery signal) is an OOK / ASK / FSK / PSK modulation signal, and the transceiver for this signal is independent of the transceiver for NR. Among them, the first signal at least includes an OOK / ASK / FSK / PSK signal based on OFDM.

[0399] The second signal (carrying trigger information for waking up the target cell; 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; and / or triggering the target cell to switch to a target cell state, which can also be described as a trigger signal) is an OOK / ASK / FSK / PSK signal. The transceiver is independent of the transceiver for NR, or can be the same transceiver as the transceiver for NR. Among them, the second signal can at least include an OOK / ASK / FSK / PSK signal based on OFDM.

[0400] The second signal (carrying trigger information for waking up the target cell; 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; and / or triggering the target cell to switch to a 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 for this signal is the same transceiver as the transceiver for NR. The signal based on the NR signal includes at least one of a reference signal based on NR and a channel. 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.

[0401] In the embodiments of the present application, when the receivers 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 receiver of NR turned on all the time, and only needs to detect the first signal and / or the second signal. The receiver of this signal only requires 1 / 10 of the power consumption of the NR receiver, thus achieving energy saving on the network side.

[0402] When the transmitter of the first signal and / or the second signal is the same as the transmitter of the uplink NR signal, the terminal can realize the function of the base station discovering the terminal only through a low-power transmitter.

[0403] 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. Therefore, the purpose of reducing the power consumption of the terminal can be achieved.

[0404] When the first signal and / or the second signal is an OFDM-based OOK / ASK / FSK / PSK modulation signal, the existing NR transceiver architecture can be utilized to further simplify the complexity of the transceiver. The detection based on OOK / ASK / FSK / PSK modulation can greatly reduce the power consumption at the receiving end, thereby achieving the effect of energy saving.

[0405] Embodiment 2: The acquisition method of uplink signal resource-related information;

[0406] The acquisition method of the uplink signal resource-related information by the terminal and / or the base station can be obtained based on one or several of the information stored in the terminal, the information configured by the neighbor cell high-layer signaling, the information configured by the core network signaling, the information sent by the broadcast signaling, and the information defined by the protocol.

[0407] For example:

[0408] The terminal needs to obtain the resource-related information after the terminal is powered on, so as to enable the discovery and / or triggering function of the terminal. Specifically, it can be through at least one of the following methods:

[0409] Method 1: Through the Public Land Mobile Network (PLMN) identifier, operating frequency point, and the stored PLMN-related information included in the SIM card. The center frequency point of the uplink signal can be a frequency point having a specific relationship with the operating frequency point of the PLMN. For example: The PLMN-related information is stored in the SIM card. When the terminal is powered on, frequency search can be performed through the PLMN information stored in the SIM card.

[0410] Method 2: Obtained based on the pre-stored information in the device for receiving / sending uplink signals. For example, the device pre-stored information in the device for receiving / sending uplink signals, the dedicated chip writing information of the uplink signal, etc. For example: When the device for receiving / sending uplink signals is in the powered-on state, the pre-stored information in the device can be read. It can also be read through the dedicated chip of the uplink signal inserted into the device.

[0411] Method 3: Obtained based on the information configured by the core network signaling. For another example: Under the jurisdiction of the same operator, the serving cell will carry information related to uplink signal resources through the non-access stratum (NAS) signaling. Here, the core network signaling can carry the generation information of the uplink signal and / or the information related to the time / frequency / space resource location.

[0412] For example: NAS messages during the PLMN selection process.

[0413] It should be noted that: When the terminal receives the NAS message, since the NAS message is transparently transmitted in the RRC message, by default, the terminal has completed synchronization, measurement, and the reception of broadcast messages.

[0414] Method 4: Obtained by the method configured by the high-layer signaling of the adjacent serving cell. For example: In the carrier aggregation (CA) scenario, the SIB information in the anchor cell of the carrier aggregation (CA) scenario carries the above-mentioned resource-related information.

[0415] Method 5: Obtain the resource-related information by configuring SIB1 through the broadcast signaling sent by the dormant cell. For example: The dormant cell still sends SIB1 information with a relatively large period in the dormant state, and the resource-related information is carried in the SIB1 information.

[0416] Method 6: Determine the resource-related information through the default parameter configuration defined by the protocol. The default parameter configuration defined by the protocol is such as the default frequency point, bandwidth, etc., or the center frequency point used by the terminal during cell search. That is: The default frequency point, bandwidth, etc. of the terminal of a specific version or the terminal that supports terminal wake-up or triggers the base station function to send signals.

[0417] It should be noted that: When the terminal cannot synchronize with the dormant base station, the resource information of the uplink signal can only be obtained based on the prior information and / or the relevant information provided by the neighboring cells. The prior information includes at least one of the following: information obtained from at least one of the SIM card, the dedicated SIM card of the uplink signal exclusive signal, the core network, the neighboring cell, etc.

[0418] When the terminal can obtain initial synchronization with the dormant base station, for example: When the dormant cell sends extremely sparse SSB information, the terminal can obtain a certain initial synchronization, or obtain the corresponding synchronization information through the SSB sent by the co-site neighboring cell.

[0419] Embodiment 3: Information carried by the uplink signal

[0420] When the uplink signal is 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 makes a judgment based on the uplink signal to determine whether it is awakened.

[0421] When the uplink signal (carrying discovery information and triggering information), the terminal sends the uplink signal at a specific resource location and carries the corresponding information for the base station to discover the terminal, and / or makes a judgment based on the uplink signal to determine whether it is awakened and / or send and / or receive a first object, and / or trigger the target cell to switch to the target cell state. After receiving the uplink signal, the base station includes at least one of the following situations:

[0422] Situation 1: After receiving the uplink signal, when the base station determines that specific conditions are met, it is directly awakened, that is: the base station sends / receives reference signals / channels / messages according to the default parameter configuration. Here, the specific conditions can be that the amplitude / phase / power / energy, etc. of the signal meet a specific threshold or a specific value or a specific value range.

[0423] Situation 2: After receiving the uplink signal, when the base station 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 when the base station is in the normal state, or an exclusive parameter configuration in the energy-saving state, or a protocol-predefined parameter configuration, etc. Taking SSB as an example, when the base station is in the dormant or energy-saving state, it does not send the SSB signal or sends an extremely sparse SSB signal, such as: a 640 ms period. When the base station detects the uplink signal and the specific conditions are met, the base station sends the SSB signal according to the default configuration, such as: a 20 ms period, or sends the SSB based on a specific parameter configuration, such as: a 320 ms or 160 ms period, or sends the SSB according to the default configuration within a specific time period, etc.

[0424] The specific conditions can be that the amplitude / phase / power / energy, etc. of the signal meet a specific threshold or a specific value or a specific value range.

[0425] Case 3: After the terminal sends an uplink signal, after a specific time interval, it receives a specific reference signal according to pre-configured or protocol-defined parameter configurations. 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 configurations can be parameter configurations different from those in the normal state of the base station, or exclusive parameter configurations in the energy-saving state, or at least one of protocol-predefined parameter configurations, etc. Taking SSB as an example, after a specific time interval after the terminal sends an uplink signal, such as: after the default T ms, the terminal receives the SSB signal according to a default 20 ms period, or receives the SSB based on specific parameter configurations, such as: according to a 320 ms or 160 ms period, or sends the SSB according to the default configuration within a specific time period, etc.

[0426] The specific time interval can be determined by at least one of protocol definition, high-layer signaling configuration, core network signaling indication, or terminal pre-storage.

[0427] Case 4: The base station can also be woken up according to the information carried by the uplink signal; or, send and / or receive the indicated specific signal and / or channel.

[0428] Case 5: The terminal can also send and / or receive the indicated specific signal and / or channel according to the information carried by the uplink signal.

[0429] The uplink signal can carry at least one of the following information:

[0430] Sequence information of specific information, that is: sequence information defined by the protocol or pre-configured, used for the base station to perform signal detection.

[0431] First indication information, such as indication information for waking up the cell, used to indicate whether to wake up the dormant cell;

[0432] Second indication information, such as specific reference signal transmission / reception indication information, used to indicate the specific reference signal transmitted / received by the cell;

[0433] Third indication information, such as cell status indication information, used to indicate the cell to switch between at least one state, or switch to the target cell state;

[0434] Fourth indication information, such as cell identification-related information, used to indicate the relevant cell information for waking up or transmitting / receiving the uplink signal / channel;

[0435] Fifth indication information, such as function trigger indication information, used to indicate the cell to turn on or off specific functions, such as: access, measurement, synchronization, positioning, energy saving, specific service transmission, etc.;

[0436] The sixth indication information, such as a terminal-specific identifier, is used to indicate a specific type or identifier of the terminal;

[0437] The seventh indication information, such as an identifier related to terminal demand information, that is: used to indicate the current service demands of the terminal, such as: access, measurement, synchronization, positioning, energy saving, specific service transmission, etc.

[0438] The following specifically describes the information carried by the uplink signal:

[0439] (1) The uplink signal is a modulated signal sequence of a specific pattern, used for the base station to receive and perform signal detection. For example: a modulated signal of a specific sequence, so that when the base station receives the uplink signal detection, it can identify the uplink signal.

[0440] It can be understood that the uplink signal does not carry other information, but only provides information related to energy detection for the base station.

[0441] For example:

[0442] (1) The uplink signal is a sequence of a fixed pattern with a length of N, such as: N consecutive all-1 sequences, after being modulated by the second K order modulation (i.e., OOK / ASK / FSK / PSK modulation), a modulated sequence with a length of N or N / (K - 1) is generated. N is an integer greater than or equal to 1.

[0443] For example: for an OOK signal, "1" is modulated into a symbol with an amplitude of A, and "0" is modulated into a symbol with an amplitude of 0 or a non-amplitude A. When the base station performs signal detection, envelope demodulation is used. If specific conditions are met after envelope demodulation, such as: detecting a signal with an energy accumulation for a period of time T or a signal with a duration of T1 that satisfies the amplitude threshold value, it is determined that the uplink signal meets the specific conditions. The information carried by this method is single.

[0444] For example: for an ASK signal, "1" is modulated into a symbol with an amplitude of A, and "0" is modulated into a non-amplitude A symbol. When the base station performs signal detection, envelope demodulation is used. If specific conditions are met after envelope demodulation, such as: detecting a signal with an energy accumulation for a period of time T or a signal with a duration of T1 that satisfies the amplitude threshold value, it is determined that the uplink signal meets the specific conditions.

[0445] For example: for an FSK signal, "1" is modulated into a symbol with a frequency of F1, "0" is modulated into a symbol with a frequency of F2, or "1" is modulated into a symbol with a frequency band of B1, and "0" is modulated into a symbol with a frequency band of B2. When the base station performs signal detection, filter demodulation is used. If the symbol energy obtained by filter demodulation at different frequencies or bandwidths meets the condition that a signal with a duration of T1 satisfies the amplitude threshold value, it is determined that the uplink signal meets the specific conditions.

[0446] The uplink signal is a sequence of specific patterns of length N, such as: a sequence with a certain time occupancy of bit "1", "1010…10" or "1…10…0". After 2 K -order modulation (i.e., OOK / ASK / FSK / PSK modulation), a modulated 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.

[0447] (2) The uplink signal carries first indication information (such as wake-up cell indication information);

[0448] The wake-up cell indication information is 1-bit information used to indicate that the target cell wakes up, that is: when the value is "1", it indicates waking up the target cell, and when the value is "0", it indicates that there is no need to wake up the target cell. The wake-up cell indication information can be sent based on specific parameter configuration.

[0449] The wake-up cell indication information can be carried by a discovery signal (such as an uplink signal carrying only discovery information), that is, when the target cell detects the discovery signal, the target cell is woken up; otherwise, the target cell considers that it has not been woken up. That is: the wake-up cell indication information is implicitly indicated by the discovery signal.

[0450] The wake-up cell indication information can 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 it at a pre-configured or protocol-defined resource location, and the pattern sequence of the specific N-bit information can be pre-stored or pre-configured. The wake-up cell indication information can be sequence information cascaded at the discovery signal or sequence information at a pre-configured or protocol-defined resource location after the sequence information of specific information. For example: after receiving the discovery signal, the base station obtains the discovery signal for demodulation 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, it is considered that the target cell is woken up; otherwise, the target cell considers that it has not been woken up.

[0451] (3) The uplink signal carries indication information of at least one of cell identification information, function identification, specific reference signal, cell status indication information, etc.

[0452] Trigger information can also be carried in the uplink signal, including: at least one of cell identification-related information, first object transmission / reception indication information, function trigger indication information, terminal requirement information-related identification, cell status indication information, etc. The above indication information can be indicated separately or jointly. The following gives specific examples:

[0453] When the above indication information is indicated separately, only typical use cases are given below:

[0454] Example 1: The uplink signal carries information related to the cell identifier:

[0455] The terminal can pre-obtain cell-related information that can be awakened or triggered, such as: frequency band list, cell list, etc. Based on the pre-configured or pre-obtained cell-related information, it can be classified according to the cell-related information, corresponding to different frequency band 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 respectively, such as: different OOK modulation pattern modulation symbol sequences correspond to different cells or cell groups, or different amplitude pattern ASK modulation symbol sequences correspond to different cells or cell groups, or different frequency domain pattern FSK modulation symbol sequences correspond 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, then according to the target cell ID or the index value of the cell list where the target cell is located, an uplink signal is generated. The terminal sends an uplink signal carrying information related to the cell identifier to the surrounding base stations.

[0456] The base station receives the uplink signal and performs detection based on the OOK / ASK / FSK / PSK modulation sequence. If the cell-related information carried in the uplink signal is consistent with the pre-configured or pre-obtained cell-related information, the base station considers the current cell as the target cell triggered by the uplink signal. The target cell then sends a specific signal and / or channel according to the trigger information carried in the uplink signal and / or protocol limitations.

[0457] For example: In the existing system, there are 1008 Physical Cell Identifiers (PCI). If only is used for cell identification, then the uplink signal only needs to carry 7-bit information.

[0458] Example 2: The uplink signal carries information indicating the transmission and / or reception of a specific reference signal;

[0459] When the uplink signal is used to trigger the transmission and / or reception of part of the reference signal by the base station, the uplink signal can carry the indication information of at least one reference signal. Different reference signals are indicated by Si bits respectively. An example is shown in Table 1:

[0460] Table 1

[0461] Function 1: SSB Function 2: SIB Function 3: TRS …… Function N: PRS S1 bits S2 bits S3 bits SN bits

[0462] When the indication information of each reference signal is only 1 bit, the value "0 or 1" can be used to indicate whether the corresponding reference signal is "transmitted / not transmitted".

[0463] When each reference signal indication information has 1 bit or more, 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 "transmission / non - transmission" of the corresponding reference signal.

[0464] If the uplink signal is used to trigger the transmission of part of the reference signals by the base station, the uplink signal can carry the indication information of at least one reference signal, and different reference signals are jointly indicated by N bits. An example is shown in Table 2:

[0465] Table 2

[0466]

[0467] Example 3: The uplink signal carries different function indication information;

[0468] When the uplink signal carries different function indication information, such as indicating at least one of functions like wake - up, measurement, synchronization, positioning, etc., different functions can be respectively indicated by Yi bits, or can be jointly indicated by at least one value or pattern in N bits for at least one function.

[0469] For example: Y1, Y2, Y3, …, YN are greater than or equal to 1. When the indication information is 1 bit, it can be indicated as "on / maintained" or "off" for the function. As shown in Table 3.

[0470] Table 3

[0471] Function 1: Wake-up Function 2: Measurement Function 3: Synchronization …… Function N: Positioning Y1 bits Y2 bits Y3 bits YN bits

[0472] Among them, different functions correspond to the transmission and / or reception of reference signals with at least one specific parameter configuration, as shown in Table 4.

[0473] Table 4

[0474]

[0475] Here, the specific function indication can be the transmission and / or reception of a specific reference signal under at least one specific parameter configuration.

[0476] For example: When the function indication is the wake - up function, and / or when the function indication information indicates "wake - up", after a certain time interval after the terminal sends the indication information, it can receive SSB / SIB1, paging, TRS, PEI signaling, etc., or send at least one of random access (RA) requests, scheduling requests SR, etc.

[0477] For another example: when the function indication is the positioning function, and / or the transmission and / or reception of a reference signal with at least one specific parameter configuration of this function indication. After a certain time interval after the terminal sends the indication information, it can receive at least one of SSB, TRS, PRS, and send SRS, etc. Among them, the parameter configuration can be pre-configured or protocol-defined.

[0478] For another example: when the function indication is measurement, and / or when the function indication is the transmission and / or reception of a reference signal with at least one specific parameter configuration. After a certain time interval after the terminal sends the indication information, it can receive at least one of SSB, TRS, CSI-RS, PT-RS, etc. Among them, the parameter configuration can be pre-configured or protocol-defined.

[0479] At least one function can also be jointly indicated by at least one value or pattern among N bits, as shown in Table 5:

[0480] Table 5

[0481] Function indication information Specific indication content Value 1 / Pattern 1 Function 1 Value 2 / Pattern 2 Function 2 Value 3 / Pattern 3 Function 1 + Function 2 …… …… <![CDATA[Value 2 N / Pattern 2 N > Function 1 + Function 3 + … + Function K

[0482] Example 4: The uplink signal carries identification information related to the terminal's demand information, that is, it is used to indicate the terminal's current service demand, such as access, measurement, synchronization, positioning, energy saving, specific service transmission, etc. The identification information related to the terminal's demand information is similar to the function indication information. For the specific indication method of the function indication information, please refer to it and will not be elaborated here. After receiving the identification information related to the terminal's demand information, the base station can further determine whether to provide corresponding services for this user according to its demand. Optionally, it sends its response information to the terminal to further indicate whether to provide corresponding services for it. In addition, the service type can also be further indicated, such as corresponding indication information for service types such as XR service, eMBB service, URLLC service, mMTC service, AIoT service, etc. After receiving the relevant indication information such as the terminal's service demand, the base station further determines whether to be awakened or triggered to send and / or receive corresponding reference signals / channels, etc. based on the indicated information.

[0483] Example 5: The uplink signal carries cell status indication information;

[0484] When the uplink signal carries different cell status indication information, such as at least one of cell statuses such as energy saving status 1, energy saving status 2,..., normal status, different cell statuses can be indicated by Xi bits respectively, or at least one function can be jointly indicated by at least one value or pattern among N bits. The following is an example:

[0485] For example: X1, X2, X3,..., XN are greater than or equal to 1. When the indication information is 1 bit, it can be indicated as "on / maintained" or "off" for this cell status. As shown in Table 6.

[0486] Table 6

[0487]

[0488] Among them, different cell states correspond to the transmission and / or reception of at least one reference signal with specific parameter configurations. As shown in Table 7.

[0489] Table 7

[0490]

[0491] (4) The uplink signal carries the terminal-specific identifier.

[0492] The uplink signal carries terminal-specific identification information, and the specific identifier can be a terminal type identifier, a terminal version identifier, or a terminal supporting a specific service, such as: an identifier of a terminal supporting latency-sensitive services (such as: XR services), an identifier of a terminal exclusive to a dormant base station service. When the base station receives the terminal-specific identifier in the uplink signal as the terminal required by the current dormant cell to be served, the cell is woken up, or the transmission and / or reception of a specific reference signal and / or is triggered.

[0493] Embodiment 4:

[0494] When the uplink signal carries discovery information and trigger information, specific sequence information can be carried respectively for the base station to perform uplink signal detection, and trigger information of the target cell can be carried. 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-persistently periodically, or repeatedly sent within a transmission window, and the base station performs amplitude / energy / frequency / bandwidth / phase, etc. 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 woken up, triggered to send / receive the first object, switched to a cell-specific state, etc. for at least one item.

[0495] When the uplink signal carries trigger information, one or more pieces of trigger information can be carried through specific sequence information. Specific examples are shown in Table 8:

[0496] Table 8

[0497]

[0498] Embodiment 5: Resource location information of the uplink signal;

[0499] The resource location of the uplink signal, including: time domain / frequency domain / spatial domain / code domain, can be obtained through at least one of the terminal memory, neighbor cell high-layer signaling configuration, core network signaling configuration, broadcast signaling, etc. The uplink signal has at least one of the following characteristics:

[0500] First item: The time-domain resource location of the uplink signal can be sent periodically or semi-persistently. The base station can continuously detect the uplink signal or detect it based on a detection window, depending on the base station implementation.

[0501] The transmission period of the uplink signal can be a default period, such as: protocol-defined, or consistent with the default period of a specific reference signal, such as: the default period of the SSB is 20 ms.

[0502] When the uplink signal is sent semi-persistently, it can start being sent when the terminal needs to wake up or trigger a specific cell to provide services for it. The transmission time of the uplink signal can be based on the System Frame Number (SFN).

[0503] Second item: The uplink signal is sent within a specific time window. This time window can be a repeating time window (as shown in Figure 5 ), or a duration window of the uplink signal (as shown in Figure 5 ), or it can be sent in a specific pattern within this time window (as shown in Figure 6 ).

[0504] Third item: When the uplink signal carries trigger information, there is an association relationship with a specific reference signal.

[0505] For example: The terminal obtains the potential location of the SSB that the dormant cell can send from the neighbor 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, which is used to trigger the dormant cell to send the SSB.

[0506] For example: The terminal detects the SSB sent by the target cell, and then sends an uplink signal at a position with a certain offset value from the SSB, which is used to trigger the transmission of a specific reference signal of the target cell, or the triggering of the cell energy-saving state, etc. As shown in Figure 7 :

[0507] For example: The terminal learns the pending transmission positions (occasions) of the SSB / SIB1 / TRS of the dormant cell based on the high-layer signaling or core network signaling of the neighbor cell or the historical serving cell, and sends an uplink signal at a certain time interval (GAP) from the specific reference signal, which is used to trigger whether the dormant cell sends the corresponding reference signal. This time interval is determined based on the offset value (Offset), as shown in Figure 8 .

[0508] 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 this association relationship can be determined based on an offset value (Offset), as Figure 9 shown:

[0509] When the first signal and the second signal are two independent signals, there is a certain time offset value between the first signal and the second signal. Among them, the second signal can correspond one-to-one with the first signal, that is: their transmission periods are the same, or the second signal can be transmitted after at least one first signal, that is: the period of the second signal is N times the period of the first signal.

[0510] When the first signal and the second signal are the same signal, the second signal can be part or all of the first signal. For example: The discovery information sequence occupies N time slot symbols, and the trigger information is K of these time slot symbols, which can be K time slot symbols starting from a specific position, or the first K or last K time slot symbols in the discovery information, or K time slot symbols with a certain pattern, where K is less than or equal to N.

[0511] Example 6:

[0512] When the terminal sends an uplink signal carrying trigger information, it needs to know the resource-related information of the corresponding signal, including one or several of the signal generation-related information, the transmission resource information, and the related information it carries.

[0513] The signal generation-related information of the uplink signal is used for both the transmitter and the receiver to determine / detect the transmission position of the uplink signal, and at least includes: the transmission frequency point, bandwidth, number of time domain units occupied, at least one segmentation number, number of IFFT points, sequence length of the uplink signal, etc. Among them, the frequency point can be the operating frequency point, center frequency point or serving frequency point of the uplink signal.

[0514] For example:

[0515] The uplink signal is an OOK-1 signal: Determine the center frequency point, number of carriers, subcarrier spacing (SCS), number of symbols (or uplink signal duration), and number of IFFT points in the frequency domain where the signal is located. Among them, the center frequency point can be the initial access frequency point / initial BWP.

[0516] In the above OOK-1 signal, as Figure 10As shown, the Low Power Wake Up Signal (LP-WUS) includes N sub-carriers (SCs). After performing the Inverse Fast Fourier Transform (IFFT) and adding a Cyclic Prefix (CP) to the LP-WUS, one OFDM symbol corresponds to a single bit.

[0517] The sub-carriers (SCs) of the Low Power Wake Up Signal (LP-WUS) are as follows:

[0518] OOK = 1 means that all SCs are used for modulation, corresponding to bit "1", or any one or several of the K-order modulation symbols corresponding to bit "1";

[0519] OOK = 0 means that all SCs have zero power (from the perspective of the baseband), corresponding to bit "0", or any one or several of the K-order modulation symbols corresponding to bit "0".

[0520] When the uplink signal is an OOK-1 signal, this 1-bit information can be used to trigger the signal of 1 OFDM symbol. In order for the base station side to detect the terminal, this signal can be repeatedly transmitted N times. The base station side receiver can continuously detect or detect the user's signal during a specific time period. The specific detection method depends on the base station implementation or the relevant information of the terminal sending the uplink signal.

[0521] The uplink signal is an OOK-2 signal: Determine the number of segments M of the signal (which can be specifically associated with the symbol length and duration occupied by the signal), up to M center frequencies, SCS, the number of carriers in each segment, the number of OFDM symbols (or the uplink signal duration), and the number of points of the IFFT.

[0522] In the above OOK-2 signal, the N SCs of the LP-WUS are further divided into M segments, each segment containing N / 2 sub-carriers, as Figure 11 shown, Figure 11 where M = 2, and there may be guard bands in between and / or around. After performing the Inverse Fast Fourier Transform (IFFT) and adding a Cyclic Prefix (CP) to the LP-WUS, the LP-WUS corresponds to parallel M-bits OOK in the frequency domain. The SCs of the LP-WUS are as follows:

[0523] OOK = 1 indicates that all SCs in the segment have been modulated, corresponding to bit "1", or any one or several of the K - order modulation symbols corresponding to bit "1".

[0524] OOK = 0 indicates that all SCs in the segment are of zero power (from the perspective of the baseband), corresponding to bit "0", or any one or several of the K - order modulation symbols corresponding to bit "0".

[0525] When the first signal is an OOK - 2 signal, M bits in the frequency domain can carry the terminal discovery signal. For example, the first signal is a specific sequence, such as M bits of 1. The base station can detect the terminal based on a sequence of a specific pattern, such as "1010…1". The receiver on the base station side can continuously detect or detect the user's signal within a specific time period. The specific detection method depends on the base station implementation or relevant information about the terminal sending the uplink signal.

[0526] The uplink signal is an OOK - 3 signal: Determine the number of segments L, SCS, the number of carriers in each segment, the number of OFDM symbols (or the duration of the uplink signal), and the number of points of the IFFT.

[0527] The N SCs of LP - WUS are divided into L segments, as Figure 12 shown Figure 12 where L = 2, there is no guard band between segments, but there may be a guard band around the segments. After performing the Inverse Fast Fourier Transform (IFFT) and adding a Cyclic Prefix (CP) operation on this LP - WUS, a Multi - tone single - bit OOK is obtained. Figure 12 where t0 and t1 in represent sequences corresponding to 0 and 1 respectively, and the SCs are:[[]]

[0528] OOK = 1 means that 1 sub - carrier (known to the UE) in each segment is modulated, and the rest of the SCs are of zero power (from the perspective of the baseband), corresponding to bit "1".

[0529] OOK = 0 indicates that all SCs in all segments are of zero power (from the perspective of the baseband), corresponding to bit "0".

[0530] If the first signal is an OOK-3 signal, the same frequency-domain sequence information can be carried in different segments, or different frequency-domain sequence information can be carried in different segments. In the case of a certain time / frequency-domain deviation at the base station side, the receiver can continuously detect in the time domain and / or perform frequency-domain scanning for the first signal detection; 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 terminal sending the first signal. The uplink signal is an OOK-4 signal: determine the symbol length and duration occupied by the uplink signal, the center frequency point in the frequency domain, the SCS, the number of frequency-domain carriers, etc., and the number of points of the IFFT.

[0531] As Figure 13 shown, N' samples are generated by M bits, and N SCs of LP-WUS are generated through transformation (DFT / least squares); signal modulation can be used or not; truncation or other additional modulation can be used, or other additional modulation can be not used. If other additional modulation is not used, then N is the same as N'. After performing the Inverse Fast Fourier Transform (IFFT) and adding a Cyclic Prefix (CP) operation on this LP-WUS, OOK-4 is obtained.

[0532] OOK-4 can be considered as an example of an OOK signal based on a single carrier (such as DFT-S-OFDM), or it can also be used as a signal generation method independent of the uplink single carrier (such as DFT-S-OFDM).

[0533] Embodiment 7: The transmission process of the uplink signal (taking the inclusion of the first signal and the second signal as an example for illustration);

[0534] Implementation method 1: The base station is awakened after receiving the uplink signal;

[0535] As Figure 14 shown, the process includes:

[0536] Step 1: The terminal sends a first signal for the surrounding sleeping cells / base stations (such as pico base stations) to discover the terminal. Among them, the discovery signal is an OOK / ASK / FSK / PSK signal based on OFDM. The first signal can be sent through an exclusive transmitter or through an NR transmitter. The first signal can be sent N times at a specific time point or within a specific time period, where N is greater than or equal to 1. The specific transmission location can be determined by one or several methods such as being configured by the high-layer signaling of the neighboring cell, being configured by the core network signaling, being sent by the broadcast signaling, or being defined by the protocol.

[0537] Step 2: The base station performs a first signal detection to obtain the information carried by the first signal, including: signal information and / or carried indication information. If the first signal meets a specific condition (i.e., the first condition), the cell is directly awakened; or, if the first signal does not meet the specific condition, the cell is not awakened. Here, the above first signal can carry M bits of information, where M is greater than or equal to 1, and the carried information includes at least one of the following:

[0538] Information related to the amplitude / phase / power / energy, etc. of the signal;

[0539] Indication information for awakening the cell.

[0540] In this embodiment, the first signal can be received based on an exclusive receiver or by an NR receiver.

[0541] Illustrative example:

[0542] Suppose the first signal is an OFDM-based OOK signal. When the base station detects the first signal, it obtains one of the information related to its amplitude / phase / power / energy, etc., 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.

[0543] Suppose the first signal is an OFDM-based OOK signal, and this signal carries N bits of indication information through modulation, etc., where N is greater than or equal to 1, for indicating the target cell to be awakened.

[0544] Specifically, the specific condition can be that the amplitude / phase / power / energy, etc. of the signal meets a specific threshold or a specific value or a specific value range.

[0545] For example, suppose the specific condition is greater than the power value threshold P0. If the base station detects that the power value P of the first signal is greater than the power value threshold P0, it is determined that the current terminal falls within the service range of the base station; otherwise, the base station determines that the current terminal does not fall within the service range of the base station.

[0546] Suppose the specific condition is greater than the amplitude threshold A0. If the base station detects that the amplitude value A of the first signal is greater than the amplitude threshold A0, it is determined that the current terminal falls within the service range of the base station; otherwise, the base station determines that the current terminal does not fall within the service range of the base station.

[0547] Suppose the specific condition is greater than the energy threshold E0. If the base station detects that the energy value E of the first signal is greater than the energy threshold E0, it is determined that the current terminal falls within the service range of the base station; otherwise, the base station determines that the current terminal does not fall within the service range of the base station.

[0548] Assume that the specific condition is that the phase value is within the range {Θmax, Θmin}. If the base station detects that the phase value θ of the first signal is within the phase value range, it is determined that the current terminal falls within the service range of the base station; otherwise, the base station determines that the current terminal does not fall within the service range of the base station. For example: when the terminal sends the first signal, different phase modulations can be performed on base stations in different directions. {0, π} is a cell in one direction, and {π, 2π} is a cell in one direction. The base station performs coherent demodulation on the received signal to obtain the value range where the phase of the first signal is located.

[0549] Assume that the specific condition is that the indication information carried by the first signal is a specific value. For example: all N bits are 1. If the base station detects that the indication information carried by the first signal meets the specific value, it is determined that the current terminal falls within the service range of the base station; otherwise, the base station determines that the current terminal does not fall within the service range of the base station.

[0550] When the base station determines that the current terminal falls within the service range of the base station, the sleeping cell is awakened and sends an SSB signal, or a CSI-RS or a reference signal for positioning to provide regular services for the terminal; otherwise, the sleeping cell will not be awakened.

[0551] Step 3: If the cell is awakened, perform at least one of the following:

[0552] Restore the service state;

[0553] Enter the light sleep state;

[0554] Send SSB / SIB1. The terminal synchronizes to the SSB sent by the awakened cell, performs cell search, random access, or sends a scheduling request, etc.

[0555] Implementation method 2: After receiving the above first signal, the base station is triggered to send / receive the first object;

[0556] Such as Figure 15 As shown, this process includes:

[0557] Step 1: The terminal sends a first signal for surrounding sleeping cells / base stations (such as: Pico) to discover the terminal. Among them, the first signal is an OFDM-based OOK / ASK / FSK / PSK signal. The first signal can be sent through a dedicated transmitter 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 several methods such as neighbor cell high-layer signaling configuration, core network signaling configuration, broadcast signaling sending, or protocol limitation.

[0558] Step 2: The base station performs a first signal detection to obtain the information carried by the first signal, including: signal information and / or the carried indication information. If the first signal meets a specific condition (i.e., the first condition), the cell is triggered to send a specific reference signal, or if the first signal does not meet the specific condition, the cell will not send a specific reference signal. Here, the first signal can carry M bits of information, where M is greater than or equal to 1, and the carried information includes at least one of the following:

[0559] The signal information carried by the first signal can be information related to the amplitude / phase / power / energy, etc. of the signal.

[0560] The indication information carried by the first signal is used to trigger the cell to receive and / or send signals.

[0561] In this embodiment, the first signal can be received through an exclusive receiver or through an NR receiver.

[0562] Illustrative example:

[0563] Suppose the first signal is an OFDM-based OOK signal. When the base station detects the first signal, it obtains one of the relevant information such as its amplitude / phase / power / energy, etc. For example: obtaining the power value of its signal as P, or obtaining the amplitude value of its signal as A, or obtaining the energy value of its signal as E, or obtaining the phase information of its signal as θ.

[0564] Specifically, the specific condition can be: the amplitude / phase / power / energy, etc. of the signal meets a specific threshold or a specific value or a specific value range.

[0565] Illustrative example:

[0566] Suppose the specific condition is greater than the power value threshold P0. If the base station detects that the power value P of the first signal is greater than the power value threshold P0, it is determined that the current terminal requires the base station side to send / receive a specific reference signal; otherwise, the base station determines that the current terminal does not require sending / receiving a specific reference signal.

[0567] Suppose the specific condition is greater than the amplitude threshold A0. If the base station detects that the amplitude value A of the first signal is greater than the amplitude threshold A0, it is determined that the current terminal requires the base station side to send / receive a specific reference signal; otherwise, the base station determines that the current terminal does not require sending / receiving a specific reference signal.

[0568] Suppose the specific condition is greater than the energy threshold E0. If the base station detects that the energy value E of the first signal is greater than the energy threshold E0, it is determined that the current terminal requires the base station side to send / receive a specific reference signal; otherwise, the base station determines that the current terminal does not require sending / receiving a specific reference signal.

[0569] Assume that the specific condition is within the phase value range {Θmax, Θmin}. If the base station detects that the phase value θ of the first signal is within the phase value range, it is determined that the current terminal requires the base station 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.

[0570] For example, when the base station determines that the current terminal requires the base station side to send / receive a specific reference signal, the sleeping cell sends a specific reference signal according to the protocol limit or according to the indication information carried by the first signal, such as: SSB signal, TRS signal, CSI-RS signal, positioning reference signal PRS / SRS, etc.; otherwise, the sleeping cell or the cell in the energy-saving state will not send / receive a specific reference signal. The configuration of the reference signal is the default parameter configuration defined by the protocol. The specific reference signal can be one or several signals defined by the protocol. For example, when the base station receives the first signal and meets the specific condition, it sends the SSB signal. The SSB signal is sent according to the default 20ms period. The same applies to other reference signals.

[0571] Assume that the specific condition is that the indication information carried by the first signal is the indication information of the specific reference signal, that is, different values correspond to different reference signals. For example, N bits respectively correspond to M kinds of reference signals, and the base station triggers the sending and / or receiving of the corresponding specific reference signal according to the indication information.

[0572] For example, when the base station receives the first signal and the first signal carries the indication information of the specific reference signal, such as: N1 bits in N bits are used to indicate the positioning reference signal PRS, the base station sends the PRS signal according to the default parameter configuration or the parameter configuration defined by the protocol. Further, when the base station determines that the current terminal requires the base station side to send / receive a specific reference signal, the sleeping cell can configure a certain parameter in multiple configurations of the specific reference signal according to the indication information. For example: when the base station receives the indication information carried by the first signal indicating the sending of the positioning reference signal PRS and indicating a certain parameter configuration in the pre-configured parameter configuration, the base station sends the specific reference signal according to the specific parameter configuration.

[0573] Step 3: In the case where the cell is triggered to send a specific reference signal, perform at least one of the following:

[0574] Send SSB / SIB1;

[0575] Send the downlink synchronization signal TRS;

[0576] Send the positioning reference signal.

[0577] The terminal synchronizes, searches for a cell, performs random access, or sends a scheduling request, etc. based on the specific reference signal sent by the sleeping cell.

[0578] Implementation method 3: The uplink signal includes a first signal and a second signal. The first signal carries discovery information, or carries discovery information and trigger information. The second signal carries discovery information and trigger information, or carries trigger information. After the base station sends the first response signal of the first signal, it is fully or partially awakened;

[0579] As Figure 16 shown, it includes:

[0580] Step 1: The terminal sends a first signal for surrounding sleeping cells / base stations (such as: Pico) to discover the terminal. Among them, the first signal is an OFDM-based OOK / ASK / FSK / PSK signal. The first signal can be sent by a dedicated transmitter for the first signal or by an NR transmitter.

[0581] Step 2: The base station performs first signal detection to obtain the information carried by the first signal, including: signal information and / or carried indication information. If the first signal meets specific conditions (i.e., the first condition), then a first response signal is sent to the terminal. Or, if the first signal does not meet specific conditions, the cell will not send a first response signal. Here, the first signal can carry M bits of information, M is greater than or equal to 1, and the carried information includes at least one of the following:

[0582] Information related to the amplitude / phase / power / energy, etc. of the signal.

[0583] Indication information for triggering the cell to receive and / or send signals.

[0584] In this embodiment, the first signal can be received by a dedicated receiver based on the first signal or by an NR receiver.

[0585] For example:

[0586] Assume that the first signal is an OFDM-based OOK signal. When the base station detects the first signal, it obtains one of the information related to its amplitude / phase / power / energy, etc. For example: obtains the power value of its signal as P, or obtains the amplitude value of its signal as A, or obtains the energy value of its signal as E, or obtains the phase information of its signal as θ.

[0587] Taking the first signal as an OOK-1 signal as an example, the first signal can carry 1 bit of information for the sleeping cell to discover the terminal. The first signal can be sent N times at a specific time point or time period, N is greater than or equal to 1, and the specific sending position can be determined by one or several methods such as neighbor cell high-layer signaling configuration, core network signaling configuration, broadcast signaling sending, or protocol limitation.

[0588] Step 3: The base station sends a first response signal to the first signal. Here, the first response signal can be sent when the signal information of the first signal detected by the base station meets specific conditions. Specifically, the specific conditions can be that the amplitude / phase / power / energy, etc. of the signal meet a specific threshold or a specific value or a specific value range. The first response signal can also be that the base station sends the first response signal as long as it detects the first signal.

[0589] For specific specific conditions, reference can be made to Embodiment 2 and Embodiment 3.

[0590] The first response signal can carry at least one of the following:

[0591] The first item: Carry the confirmation information of the cell receiving the first signal. For example: N-bit ACK information. Here, the first response signal can be an OFDM-based OOK / ASK / FSK / PSK signal.

[0592] For example: If the base station detects that the amplitude of the signal is higher than a specific threshold within a certain period of time, it is determined that a terminal has entered the service range of this cell. Therefore, the base station determines that it needs to be awakened and sends a first response signal to the terminal. For example: Carry a 1-bit OOK signal. After sending the first signal, the terminal performs the reception detection of the first response signal within a specific time interval.

[0593] The second item: Carry the cell information of this cell, etc. For example: The cell information can be a predefined sequence or signal pattern, etc. Here, the first response signal can be an OFDM-based OOK / ASK / FSK / PSK signal. The predefined sequence or signal pattern corresponding to the cell information can be information pre-configured by the terminal, or limited by neighboring cells or the core network or protocols.

[0594] For example: If the base station detects that the amplitude of the signal is higher than a specific threshold within a certain period of time, it is determined that a terminal has entered the service range of this cell. Therefore, the base station determines that it needs to be awakened and sends a first response signal to the terminal. This first response signal includes M-bit information corresponding to the cell information pre-configured or pre-defined by the cell. After sending the first signal, the terminal performs the reception detection of the first response signal within a specific time interval.

[0595] The third item: The cell sends feedback information on the indication information carried by the first signal. For example: The feedback information carried by the first signal.

[0596] For example: If the N-bit information of the first signal carries the indication information of M1 specific reference signals and / or M2 specific parameter configurations, then when the base station detects the first signal and meets specific conditions, it sends the feedback information corresponding to the indication information to the terminal, that is, the confirmation information of the indication information of the m1th specific reference signal and / or the confirmation information of the indication information of the m2th parameter configuration.

[0597] Item 4: A reference signal for the terminal to perform time-frequency synchronization, such as: SSB signal.

[0598] For example: If the base station detects that the amplitude of the signal is higher than a specific threshold within a certain period of time, it is determined that a terminal has entered the service range of this cell. Therefore, the base station determines that it needs to be woken up and sends a response signal to the terminal. This first response signal is a specific reference signal, such as: the SSB signal for terminal time-frequency synchronization.

[0599] Step 4: After the specific cell sends the first response signal, perform at least one of the following:

[0600] Restore the service state, that is, be fully woken up;

[0601] Enter the light sleep state;

[0602] Send SSB / SIB1;

[0603] Send the downlink synchronization signal TRS;

[0604] Send the positioning reference signal.

[0605] Step 5: After the terminal receives the first response signal, receive the SSB or the specific reference signal, and perform synchronization, cell search, random access, or send a scheduling request, etc.

[0606] Implementation method 4: The uplink signal includes a first signal and a second signal. The first signal carries discovery information, or carries discovery information and trigger information. The second signal carries discovery information and trigger information, or carries trigger information.

[0607] Such as Figure 17 shown, this process includes:

[0608] Step 1: The terminal sends a first signal for the surrounding sleeping cells / base stations (such as: Pico) to discover the terminal. Among them, the first signal is an OFDM-based OOK / ASK / FSK / PSK signal. The first signal can be sent through a dedicated transmitter for the first signal, or through an NR transmitter.

[0609] Step 2: The base station performs first signal detection and obtains the information carried by the first signal, including: signal information and / or carried indication information. Here, the information carried by the first signal includes at least one of the following:

[0610] The signal information carried by the first signal can be information related to the amplitude / phase / power / energy, etc. of the signal.

[0611] The indication information carried by the first signal is used to trigger the cell to receive and / or send signals.

[0612] In this embodiment, the first signal can be received by a dedicated receiver based on the first signal or by an NR receiver.

[0613] For example:

[0614] Assume that the first signal is an OFDM-based OOK signal. When the base station detects the first signal, it obtains one of the relevant information such as amplitude / phase / power / energy, etc. For example: obtaining the power value of its signal as P, or obtaining the amplitude value of its signal as A, or obtaining the energy value of its signal as E, or obtaining the phase information of its signal as θ.

[0615] Step 3: The base station sends a first response signal of the first signal. Here, the first response signal can be sent when the signal information of the first signal detected by the base station meets specific conditions. Specifically, the specific conditions can be: the amplitude / phase / power / energy, etc. of the signal meet a specific threshold or a specific value or a specific value range. The first response signal can also be that when the base station detects the first signal, it will send the first response signal.

[0616] For the specific specific conditions, reference can be made to Embodiment 2 and Embodiment 3.

[0617] The first response signal can be at least one of the following situations:

[0618] The first item: carrying the confirmation information of the cell receiving the first signal. For example: N-bit ACK information, used to indicate that the base station has detected the first signal.

[0619] The second item: carrying the cell information of this cell, etc. For example: the cell information can be a predefined sequence or a signal pattern, etc.

[0620] The third item: the feedback information of the cell on the indication information carried by the first signal. For example: the feedback information carried by the first signal.

[0621] The fourth item: the specific reference signal (i.e., the second reference signal) sent / received by the cell.

[0622] For example:

[0623] If the first signal is used to wake up a sleeping cell, the base station sends a first response signal to confirm that it has been woken up.

[0624] If the first signal carries the relevant information of the cell, the base station sends a first response signal to feedback whether it is the target cell for the terminal to wake up.

[0625] If the first signal carries the indication information for sending / receiving the triggered first target reference signal, the base station makes a feedback according to the indication information.

[0626] If the base station sends a first response signal to the terminal after receiving the first signal, the first response signal includes acknowledgment information and / or a specific reference signal, such as at least one of an SSB signal, an SIB signal, etc.

[0627] Step 4: After receiving the first response signal, the terminal receives a specific reference signal (second reference signal), such as an SSB, for synchronization and cell search. If the current cell meets the cell search or cell reselection condition, 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.

[0628] Illustrative example:

[0629] If the second signal is an OFDM-based OOK / ASK / FSK / PSK signal, the generation method and the carried information can refer to the uplink signal in Embodiment 6 above.

[0630] 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 an exclusive signaling for cell wake-up.

[0631] The second signal can carry at least one of the following information:

[0632] First indication information, such as indication information for waking up a cell, used to indicate whether to wake up a dormant cell;

[0633] Second indication information, such as indication information for specific reference signal transmission / reception, used to indicate the specific reference signal transmitted / received by the cell;

[0634] Third indication information, such as cell status indication information, used to indicate switching between at least one state or switching to a target cell state;

[0635] Fourth indication information, such as cell identification related information, used to indicate the relevant cell information for waking up or the transmission / reception of uplink signals / channels;

[0636] Fifth indication information, such as function trigger indication information, used to indicate turning on or off a specific function of the cell, such as access, measurement, synchronization, positioning, energy saving, specific service transmission, etc.;

[0637] Sixth indication information, such as a terminal specific identification, used to indicate a specific type or terminal identification of the terminal;

[0638] Seventh indication information, such as an identifier related to terminal demand information, that is, used to indicate the current service demand of the terminal, such as access, measurement, synchronization, positioning, energy saving, specific service transmission, etc.

[0639] Step 5: After a specific cell receives a second signal for sending a transmission / reception indication for waking up or triggering a specific reference signal, perform at least one of the following:

[0640] Resume the service state, i.e., wake up;

[0641] Enter the light sleep state;

[0642] Send SSB / SIB1;

[0643] Send the downlink synchronization signal TRS;

[0644] Send the positioning reference signal.

[0645] That is, after receiving the second signal, it is woken up or partially woken up, or transmits / receives a specific reference signal, SSB, measured CSI-RS, or synchronization signal, etc.

[0646] Here, partial wake-up means that the base station only transmits and / or receives part of the reference signals, or switches to parameter configuration in the energy-saving state, etc. For details, refer to Embodiment 4.

[0647] In the embodiments of the present application, the above OOK / ASK / FSK / PSK signals are low-power signals different from OFDM signals. The processing method of this low-power signal is different from the processing method of existing OFDM signals. Cells in the sleep state or energy-saving state can process this low-power signal, so that through this low-power signal, the terminal can communicate with the sleeping cell or the cell in the energy-saving state without synchronization, thereby achieving the purpose of waking up the sleeping cell or triggering the sleeping cell to wake up to provide services.

[0648] As Figure 18 shown, the embodiments of the present application also provide a signal transmission method, which is executed by a network-side device. The method includes:

[0649] Step 1801: Receive an uplink signal, where the uplink signal carries at least one of discovery information and trigger information;

[0650] Wherein, the discovery information is used to discover the terminal; the trigger information is used for at least one of the following:

[0651] Wake up the target cell;

[0652] Trigger the target cell to transmit and / or receive a first object, where the first object includes at least one of a first reference signal and a first channel;

[0653] Trigger the target cell to switch to the target cell state.

[0654] Optionally, the above target cell includes at least one of a cell in a dormant state, a cell in a closed state, a cell in a sleep state, and a cell in an energy-saving state. The target cell may be a primary serving cell or a secondary cell, and the target cell has a cell identification ID.

[0655] Optionally, the above first reference signal includes at least one of the following: Primary Synchronisation Signal (PSS), Secondary Synchronisation Signal (SSS), Synchronization Signal Block (SSB), CSI Reference Signal for Tracking (TRS), Positioning Reference Signal (PRS), Phase-tracking reference signal (PT-RS), random access preamble, Sounding Reference Signal (SRS), Demodulation Reference Signal (DMRS), CSI Reference Signal (CSI-RS).

[0656] Optionally, 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), Physical Uplink Shared Channel (PUSCH).

[0657] The above first object is defined by the protocol or pre-configured by high-layer signaling.

[0658] In an embodiment of the present application, an uplink signal is received, where the uplink signal carries at least one of discovery information and trigger information; wherein, the discovery information is used to discover a terminal; the trigger information is used for at least one of the following: waking up a target cell; 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; triggering the target cell to switch to a first state. Thus, through the above discovery information and / or trigger information, the purpose of waking up a dormant cell or triggering a dormant cell to wake up to provide services can be achieved.

[0659] Optionally, the uplink signal includes at least one modulation signal, and the modulation signal includes at least one of an on-off keying (OOK) modulation signal, an amplitude shift keying (ASK) modulation signal, a frequency shift keying (FSK) modulation signal, and a phase shift keying (PSK) modulation signal.

[0660] The above OOK / ASK / FSK / PSK signal is a low-power signal different from an OFDM signal, and the processing method of this low-power signal is different from that of existing OFDM signals. A cell in a dormant state or an energy-saving state can process this low-power signal, so that through this low-power signal, a terminal can communicate with a dormant cell or a cell in an energy-saving state without synchronization, and further achieve the purpose of waking up a dormant cell or triggering a dormant cell to wake up to provide services.

[0661] Optionally, the modulation signal is a signal based on orthogonal frequency division multiplexing (OFDM).

[0662] When the above modulation signal is an OFDM-based OOK / ASK / FSK / PSK signal, the architecture of an existing NR transceiver can be utilized, further avoiding the addition of a new transceiver, thereby simplifying the complexity of the transceiver. For signal detection based on OOK / ASK / FSK / PSK modulation, since there is no need to perform an inverse Fourier transform (IFFT) operation but envelope, filtering, or phase detection, the power consumption at the receiving end can be greatly reduced, thus achieving an energy-saving effect.
