Description

Technical Field

[0001] The present application belongs to the field of wireless communication technology, and specifically relates to a signal receiving method, sending method, device, terminal and network-side equipment. Background Art

[0002] In the related art, when the network side needs to wake up the terminal or assist the terminal in synchronization, it needs to send low-power signals, such as low-power wake-up signals (LP-WUS) and low-power synchronization signals (LP-SS). Terminals with low-power wake-up receivers will monitor low-power signals. Low-power signals are usually on-off keying (OOK) signals.

[0066] The following is a brief description of the technical content involved in this application.

[0067] 1.1 Low Power Receiver

[0068] Low power receiver, also known as Low Power Wake Up Radio (LP-WUR) or Almost Zero Power Wake Up Radio (AZP-WUR). The basic working principle of the low power receiver is as follows: The receiving end includes a first module and a second module, as shown in the following example: Figure 2 As shown, the first module is the main communication module, which is used to receive the communication data transmitted by the transmitter and send the communication data, and the second module is the low-power receiving module (also called the low-power wake-up receiving module), which is used to receive the low-power wake-up signal (LP-WUS) and low-power synchronization signal (LP-SS) sent by the transmitter. The low-power wake-up signal is used to wake up the main communication module of the receiving end, and the low-power synchronization signal is used to provide time reference information and other information for receiving the low-power wake-up signal, for example, for performing radio resource management (RRM) measurement of the serving cell, and can also provide wake-up link management, such as determining whether to activate / deactivate the low-power receiving module based on the measurement results, and shutting down the main communication module. As shown Figure 2As shown in the figure, the terminal turns on the low-power receiving module in the energy-saving state to listen for the low-power wake-up signal and turns off the main communication module. When downlink data arrives, the network sends a low-power wake-up signal to the terminal. After the terminal listens to the low-power wake-up signal through the low-power receiving module, it triggers the main communication module from off to on after a series of judgments. At this time, the low-power receiving module goes from the working state to the off state. The low-power wake-up receiving module can be turned on continuously or intermittently. When turned on, it can receive low-power wake-up signals and low-power synchronization signals.

[0069] 1.2 Low Power Wake-up Signal (LP-WUS)

[0070] To reduce a terminal's reception activity in standby mode, effectively shutting down the radio frequency (RF) and baseband (MODEM) modules, thereby significantly reducing power consumption during communication reception, this can be achieved by integrating the aforementioned low-power receiver into the terminal's receiving module. In one embodiment, this near-zero-power receiver eliminates the complex signal detection (e.g., amplification, filtering, quantization, etc.) required by the RF module and the signal processing required by the MODEM, relying solely on passive matched filtering and low-power signal processing.

[0071] In one embodiment, the low power wake-up signal is some relatively simple on-off keying (OOK) signal, and the time domain pattern of the on-off keying signal is as follows: Figure 3 As shown, the low-power receiver can obtain the wake-up notification through simple energy detection and subsequent possible sequence detection and identification processes. In another embodiment, the low-power wake-up signal can be a frequency-shift keying (FSK) signal, an orthogonal frequency division multiplexing (OFDM) signal, or a mixed signal of OFDM and OOK or FSK. In addition, while the terminal turns on the low-power receiver (i.e., the low-power receiving module) to receive the wake-up signal, the main communication receiver (i.e., the main communication receiving module) can maintain operation at a lower power consumption level, thereby achieving power saving.

[0072] Receiving the low-power wake-up signal can be applied to a terminal in a Radio Resource Control (RRC) idle state / inactive state (RRC_idle / inactive), and can also be applied to a terminal in a connected state (RRC_connected), thereby achieving terminal energy saving.

[0073] Since OFDM is commonly used in existing New Radio (NR) systems, OOK signals can be generated using OFDM signal generation methods. For example, the transmission or non-transmission of an OFDM-modulated sequence represents an ON / OFF switch in the time domain.

[0074] Furthermore, the OFDM modulation sequence of modulation ON can further carry information through different sequences, for example, two sequences represent 0 and 1 information respectively, or four sequences represent 00, 01, 10, and 11 information respectively, such as Figure 4 shown.

[0075] like Figure 4 As shown, part of the information is carried through OOK modulation, and the other part of the information is carried through the OFDM sequence of the ON level.

[0076] 1.3 Low Power Synchronization Signal (LP-SS)

[0077] The LP-SS signal is a signal that is sent periodically to convey time information. The receiving end can obtain time synchronization information by receiving the LP-SS signal. In some embodiments, mobility measurement or channel measurement can also be performed by receiving the LP-SS signal. Both LP-SS and LP-WUS are received by a low-power receiver. In one embodiment, LP-SS can be regarded as a downlink synchronization signal for LP-WUS reception. In another embodiment, the LP-SS signal can also be used for terminal mobility measurement, such as cell selection or cell reselection, cell handover, and other functions. In addition, optionally, the sequence of the LP-SS signal can have a certain correlation with the LP-WUS sequence. For example, the LP-SS signal sequence is part of the LP-WUS sequence.

[0078] 1.4 Downlink Signal Waveform

[0079] 1) OOK

[0080] There are two ways to generate OOK modulation: one is a multi-carrier OOK signal (MC-OOK) based on the OFDM architecture, and the other is a single-carrier OOK signal.

[0081] For multi-carrier OOK signals based on OFDM architecture, the design idea is to not change the transmitting architecture of the existing base station. Therefore, appropriate data is sent on the OFDM subcarrier to make it appear as a square wave signal in the time domain. The generation framework is as follows: Figure 5 shown.

[0082] Multi-carrier OOK signals based on OFDM architecture can be divided into:

[0083] a)OOK-1

[0084] OOK-1 is mainly an OFDM symbol carrying one bit of information (such as Figure 6 As shown, the OOK-1 waveform includes a high-level bit. When bit 1 is transmitted, data is transmitted in the frequency domain of the corresponding symbol. When bit 0 is transmitted, nothing is transmitted in the frequency domain of the corresponding symbol. To increase the transmission rate, the subcarrier spacing (SCS) needs to be increased. Frequency domain data can use ZC sequences, quadrature amplitude modulation (QAM) signals, and other methods to ensure frequency domain signal flatness. Assuming power pooling is not performed between symbols, nothing is transmitted in the OFDM signal where no bits are transmitted, resulting in a certain power loss.

[0085] b)OOK-4

[0086] The OOK-4 waveform is one of the more flexible waveforms, capable of controlling the transmission rate by adjusting the number of bits transmitted within an OFDM symbol. OOK-4 can be generated in two ways: using DFT-S-FDM and least squares (LS). The DFT-S-OFDM approach is to first generate the desired waveform in the time domain, where the number of sampling points equals the number of resource elements (REs) in the WUS bandwidth. The frequency domain information is then obtained through a discrete Fourier transform (DFT). The least squares (LS) method also uses the desired time domain waveform to infer the frequency domain waveform. It primarily optimizes the input frequency domain sequence X using the Fast Fourier Transform (FFT) matrix and the ideal time domain waveform.

[0087] The OOK-4 waveform of the low-power signal is characterized by the following characteristics: one OFDM symbol contains M bits / chips. Figure 7 , M=4, the OOK-4 waveform includes four bits, namely high level, low level, low level and high level (ie 1001).

[0088] For single-carrier OOK signals, a unipolar non-return-to-zero code sequence is used to control the on and off of the incident carrier or continuous wave (CW). Its modulation method is simple and suitable for low-power signals.

[0089] Since the Orthogonal Frequency Division Multiplexing (OFDM) signal modulation method is commonly used in existing NR systems. The OOK signal can be generated by the OFDM signal generation method, for example, by sending or not sending the OFDM modulated sequence, indicating the on / off switch (ON / OFF) in the time domain. For a low-power receiver, as long as energy is detected on the current sequence, it is 1, and if not, it is 0. Therefore, from the perspective of the network side, it can be considered to use the existing downlink (DL) signal channel (such as the Channel State Information Reference Signal (CSI-RS), the Physical Downlink Control Channel (PDCCH), and the Synchronization Signal and PBCH block (SSB)) to send low-power signals, thereby reducing network overhead.

[0090] The signal receiving method, sending method, apparatus, terminal and network-side equipment provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0097] In an embodiment of the present application, the terminal is a terminal (UE with LP-WUR) with a low power receiver (LP-WUR). The low power receiver of the terminal receives the NR downlink signal at the second downlink resource position originally configured for the low power signal, or at the fourth downlink resource position obtained after adjusting the second downlink resource position. The NR downlink signal is demodulated according to whether the energy of the NR downlink signal is detected. Therefore, when the resources of the low power signal and the NR downlink signal overlap, the network side only needs to send the NR downlink signal, and does not need to send the low power signal, thereby saving resources on the network side.

[0151] Optionally, the terminal receives first indication information sent by a network side device.

[0152] Of course, in some other embodiments, the network-side device may also directly indicate the third downlink resource location to the terminal.

[0160] In some embodiments, optionally, the first threshold is related to at least one of SNR, SINR, RSRP, and RSRQ.

[0161] In some embodiments, optionally, the first signal includes at least one of the following: CSI-RS, PDCCH, SSB, PT-RS, DMRS, PRS.

[0162] In some embodiments, optionally, the second signal includes at least one of the following: LP-SS, LP-WUS.

[0163] Please refer to Figure 10 , an embodiment of the present application further provides a signal sending method, including:

[0164] Step S31: The network side device sends a first signal at the first downlink resource position or the third downlink resource position;

[0165] The first downlink resource position is a downlink resource position configured for the first signal;

[0166] The third downlink resource position is a second downlink resource position configured according to the first downlink resource position and the second signal, and is a downlink resource position obtained by adjusting the first downlink resource position;

[0167] The first signal is an NR downlink signal, and the second signal is a low power consumption signal.

[0168] In the embodiment of the present application, it is clarified that the network side device can determine whether to send the NR downlink signal at the original first downlink resource position of the NR downlink signal, or at the third downlink resource position obtained after adjusting the first downlink resource position, based on the downlink resource positions of the NR downlink signal and the low power consumption signal. In the case where the resources of the low power consumption signal and the NR downlink signal overlap, it is only necessary to send the NR downlink signal, and there is no need to send the low power consumption signal, thereby saving resources on the network side.

[0169] In some embodiments, optionally, the first signal includes at least one of the following: CSI-RS, PDCCH, SSB, PT-RS, DMRS, PRS.

[0170] In some embodiments, optionally, the second signal includes at least one of the following: LP-SS, LP-WUS.

[0171] The downlink resource locations in the embodiments of the present application include time domain resources and frequency domain resources.

[0172] In some embodiments, optionally, the signal sending method further includes: the network side device determines to send the first signal at the first downlink resource location or the third downlink resource location.

[0173] In some embodiments, optionally, the network side device determines to send the first signal at the first downlink resource location or the third downlink resource location, including: when the first downlink resource location and the second downlink resource location are exactly the same or there is partial overlap, and the second signal needs to be sent at the second downlink resource location, the network side device determines to send only the first signal, and determines to send the first signal at the first downlink resource location.

[0174] In the embodiment of the present application, the second signal needs to be sent at the second downlink resource location, which can also be described as having a second signal that needs to be sent at the second downlink resource location.

[0175] Please refer to Figure 11 In case 1, the second downlink resource position of the LP-SS (second signal) and the first downlink resource position of the CSI-RS (first signal) are exactly the same, and the LP-SS needs to be sent at the second downlink resource position. In this case, the LP-SS can be omitted and only the CSI-RS can be sent to save resources on the network side. The CSI-RS is determined to be sent at the first downlink resource position of the CSI-RS, and there is no need to adjust the first downlink resource position. The low-power receiver on the terminal can detect the energy of the CSI-RS at the second downlink resource position (first downlink receiving resource). If the energy of the CSI-RS exceeds the first threshold, it is determined that the information carried on the OFDM symbol is bit 1, otherwise it is bit 0. However, the legacy UE receives the CSI-RS at the first downlink resource position and demodulates the CSI-RS normally.

[0176] Please refer to Figure 11In case 2, the second downlink resource position of the LP-SS (second signal) and the first downlink resource position of the CSI-RS (first signal) partially overlap, and the LP-SS needs to be sent at the second downlink resource position. In this case, the LP-SS can be omitted and only the CSI-RS can be sent to save resources on the network side. The CSI-RS is determined to be sent at the first downlink resource position of the CSI-RS, and there is no need to adjust the first downlink resource position. The low-power receiver on the terminal can detect the energy of the CSI-RS at the second downlink resource position (energy can be detected at the overlapping downlink resource position). If the energy of the CSI-RS exceeds the first threshold, it is determined that the information carried on the OFDM symbol is bit 1, otherwise it is bit 0. However, the legacy UE receives the CSI-RS at the first downlink resource position and demodulates the CSI-RS normally.

[0177] For example, the network device sends SSB at a 20ms period and LP-SS at a 160ms period. During the 160ms, the network device needs to assist the terminal (UE with LP-WUR) in synchronizing the transmission of LP-SS and SSB. Therefore, during the 160ms, the network device needs to send both signals simultaneously, increasing network overhead. Since the terminal (UE with LP-WUR) only needs to detect whether there is energy in the current time unit to detect the low-power signal, the network device can only send the SSB signal where the SSB and LP-SS transmission resources overlap, reducing network overhead.

[0178] In some embodiments, optionally, the network side device determines to send the first signal at the first downlink resource location or the third downlink resource location, including: when the first downlink resource location and the second downlink resource location are exactly the same or partially overlap, and there is no need to send the second signal at the second downlink resource location, the network side device determines to send only the first signal, and adjusts the frequency domain resources of the first downlink resource location according to the first frequency domain offset so that the frequency domain resources of the adjusted first downlink resource location and the frequency domain resources of the second downlink resource location do not overlap, and uses the adjusted first downlink resource location as the third downlink resource location, and determines to send the first signal at the third downlink resource location.

[0179] Please refer to Figure 12In cases 3 and 4, the second downlink resource position of the LP-SS (second signal) and the first downlink resource position of the CSI-RS (first signal) are exactly the same or partially overlap, and there is no need to send the LP-SS at the second downlink resource position. In this case, the LP-SS is not sent, only the CSI-RS is sent. In order to prevent the low-power receiver on the terminal from detecting the signal at the second downlink resource position, it is necessary to adjust the first downlink resource position of the CSI-RS and send the CSI-RS at the third downlink resource position obtained after the adjustment. The low-power receiver on the terminal can detect the energy of the CSI-RS at the second downlink resource position. If the energy of the CSI-RS exceeds the first threshold, the information on the OFDM symbol is determined to be bit 1, otherwise it is bit 0. The legacy UE receives the CSI-RS at the third downlink resource position and demodulates the CSI-RS normally.

[0180] In some embodiments, optionally, the network side device determines to send the first signal at the first downlink resource position or the third downlink resource position, including: when the time domain resources of the first downlink resource position and the second downlink resource position are the same, but the frequency domain resources of the first downlink resource position and the second downlink resource position do not overlap, and it is necessary to send the second signal at the second downlink resource position, the network side device determines to send only the first signal, and adjusts the frequency domain resources of the first downlink resource position according to the first frequency domain offset, so that the frequency domain resources of the adjusted first downlink resource position and the frequency domain resources of the second downlink resource position at least partially overlap, and uses the adjusted first downlink resource position as the third downlink resource position, and determines to send the first signal at the third downlink resource position.

[0181] Please refer to Figure 13In case 5, the second downlink resource location of the LP-SS (second signal) and the first downlink resource location of the CSI-RS (first signal) have the same time domain resources, but do not overlap in frequency domain resources. Furthermore, the LP-SS needs to be sent in the second downlink resource location. In this case, to save network resources, the LP-SS can be omitted and only the CSI-RS can be sent. The first downlink resource location of the CSI-RS can be adjusted so that the frequency domain resources of the adjusted first downlink resource location and the second downlink resource location at least partially overlap (e.g., completely overlap), and the CSI-RS is sent in the third downlink resource location obtained after the adjustment. A low-power receiver on the terminal can detect the energy of the CSI-RS in the second downlink resource location (i.e., the third downlink resource location). If the CSI-RS energy exceeds a first threshold, the information carried in the OFDM symbol is determined to be bit 1; otherwise, it is determined to be bit 0. The legacy UE receives the CSI-RS in the third downlink resource location and demodulates the CSI-RS normally.

[0182] In some embodiments, optionally, the network side device determines to send the first signal at the first downlink resource position or the third downlink resource position, including: when the frequency domain resources of the first downlink resource position and the second downlink resource position are the same, but the time domain resources of the first downlink resource position and the second downlink resource position do not overlap, and it is necessary to send the second signal at the second downlink resource position, the network side device determines to send only the first signal, and adjusts the time domain resources of the first downlink resource position according to the first time offset, so that the time domain resources of the adjusted first downlink resource position and the time domain resources of the second downlink resource position at least partially overlap, and uses the adjusted first downlink resource position as the third downlink resource position, and determines to send the first signal at the third downlink resource position.

[0183] Please refer to Figure 13In case 6, the second downlink resource location of the LP-SS (second signal) and the first downlink resource location of the CSI-RS (first signal) have the same frequency domain resources, but do not overlap in time domain resources. Furthermore, the LP-SS needs to be sent in the second downlink resource location. In this case, to save network resources, the LP-SS can be omitted and only the CSI-RS can be sent. The first downlink resource location of the CSI-RS can be adjusted so that the frequency domain resources of the adjusted first downlink resource location and the second downlink resource location at least partially overlap (e.g., completely overlap), and the CSI-RS is sent in the third downlink resource location obtained after the adjustment. A low-power receiver on the terminal can detect the energy of the CSI-RS in the second downlink resource location (i.e., the third downlink resource location). If the CSI-RS energy exceeds a first threshold, the information on the OFDM symbol is determined to be bit 1; otherwise, it is determined to be bit 0. The legacy UE receives the CSI-RS in the third downlink resource location and demodulates the CSI-RS normally.

[0184] In some embodiments, optionally, the network side device determines to send the first signal at the first downlink resource position or the third downlink resource position, including: when there is no overlap in the time domain resources and frequency domain resources of the first downlink resource position and the second downlink resource position, and it is necessary to send the second signal at the second downlink resource position, the network side device determines to send only the first signal, and adjusts the frequency domain resources of the first downlink resource position according to a third frequency domain offset, and adjusts the time domain resources of the first downlink resource position according to a third time offset, so that the time domain resources of the adjusted first downlink resource position and the time domain resources of the second downlink resource position at least partially overlap, the frequency domain resources of the adjusted first downlink resource position and the frequency domain resources of the second downlink resource position at least partially overlap, and uses the adjusted first downlink resource position as the third downlink resource position, and determines to send the first signal at the third downlink resource position.

[0185] Please refer to Figure 13In case 7, the frequency domain resources and time domain resources of the second downlink resource location of the LP-SS (second signal) and the first downlink resource location of the CSI-RS (first signal) do not overlap, and the LP-SS needs to be sent in the second downlink resource location. In this case, to save network resources, the LP-SS can be omitted and only the CSI-RS can be sent. In this case, the first downlink resource location of the CSI-RS can be adjusted so that the frequency domain resources of the adjusted first downlink resource location and the frequency domain resources of the second downlink resource location at least partially overlap (e.g., completely overlap), and the CSI-RS is sent in the third downlink resource location obtained after the adjustment. The low-power receiver on the terminal can detect the energy of the CSI-RS in the second downlink resource location. If the energy of the CSI-RS exceeds a first threshold, the information on the OFDM symbol is determined to be bit 1, otherwise it is determined to be bit 0. The legacy UE receives the CSI-RS in the third downlink resource location and demodulates the CSI-RS normally.

[0186] In some embodiments, optionally, the signal sending method also includes: the network side device sends first indication information, the first indication information is used to indicate the first frequency domain offset, or, indicate the first time offset, or, indicate the third time offset and the third frequency domain offset.

[0187] In some embodiments, optionally, it is not excluded that the network side device directly indicates the third downlink resource location to the terminal.

[0188] In some embodiments, optionally, the first frequency domain offset is agreed upon by a protocol;

[0189] In some embodiments, optionally, the first time offset is agreed upon by a protocol;

[0190] In some embodiments, optionally, the third time offset and the third frequency domain offset are agreed upon by a protocol.

[0191] In the above embodiments, the first downlink resource position of the first signal is adjusted. Of course, the second downlink resource position of the second signal may also be adjusted.

[0192] In some embodiments, optionally, the network side device determines to send the first signal at the first downlink resource location or the third downlink resource location, including: when the first downlink resource location and the second downlink resource location are exactly the same or partially overlap, and there is no need to send the second signal at the second downlink resource location, the network side device determines to send only the first signal, and adjusts the frequency domain resources of the second downlink resource location according to the second frequency domain offset so that the frequency domain resources of the adjusted second downlink resource location and the frequency domain resources of the first downlink resource location do not overlap, and determines to send the first signal at the first downlink resource location.

[0193] Please refer to Figure 14 In cases 8 and 9, the second downlink resource position of the LP-SS (second signal) and the first downlink resource position of the CSI-RS (first signal) are exactly the same or partially overlap, and there is no need to send the LP-SS at the second downlink resource position. In this case, the LP-SS is not sent, and only the CSI-RS is sent. In order to prevent the low-power receiver of the terminal with a low-power receiver from detecting the energy of the CSI-RS at the second downlink resource position, the second downlink resource position is adjusted. The low-power receiver on the terminal can detect the energy of the CSI-RS at the fourth downlink resource position obtained after the adjustment. If the energy of the CSI-RS exceeds the first threshold, the information on the OFDM symbol is determined to be bit 1, otherwise it is bit 0. However, the legacy UE receives the CSI-RS at the first downlink resource position and demodulates the CSI-RS normally.

[0194] In some embodiments, optionally, the network side device determines to send the first signal at the first downlink resource location or the third downlink resource location, including: when the time domain resources of the first downlink resource location and the second downlink resource location are the same, but the frequency domain resources of the first downlink resource location and the second downlink resource location do not overlap, and it is necessary to send the second signal at the second downlink resource location, the network side device determines to send only the first signal, and adjusts the frequency domain resources of the second downlink resource location according to the second frequency domain offset, so that the frequency domain resources of the first downlink resource location and the adjusted frequency domain resources of the second downlink resource location at least partially overlap, and determines to send the first signal at the first downlink resource location.

[0195] Please refer to Figure 15In case 10, the time domain resources of the second downlink resource location of the LP-SS (second signal) and the first downlink resource location of the CSI-RS (first signal) are the same, but the frequency domain resources do not overlap. Furthermore, the LP-SS needs to be sent in the second downlink resource location. In this case, to save network resources, the LP-SS can be omitted and only the CSI-RS can be sent. The second downlink resource location of the LP-SS can be adjusted so that the frequency domain resources of the adjusted second downlink resource location at least partially overlap (e.g., completely overlap) with those of the first downlink resource location, and the CSI-RS is sent in the first downlink resource location. A low-power receiver on the terminal can detect the energy of the CSI-RS in the adjusted second downlink resource location. If the CSI-RS energy exceeds a first threshold, the information on the OFDM symbol is determined to be bit 1; otherwise, it is determined to be bit 0. The legacy UE receives the CSI-RS in the first downlink resource location and demodulates the CSI-RS normally.

[0196] In some embodiments, optionally, the network side device determines to send the first signal at the first downlink resource position or the third downlink resource position, including: when the frequency domain resources of the first downlink resource position and the second downlink resource position are the same, but the time domain resources of the first downlink resource position and the second downlink resource position do not overlap, and it is necessary to send the second signal at the second downlink resource position, the network side device determines to send only the first signal, and adjusts the time domain resources of the second downlink resource position according to the second time offset, so that the time domain resources of the first downlink resource position and the adjusted time domain resources of the second downlink resource position at least partially overlap, and determines to send the first signal at the first downlink resource position.

[0197] Please refer to Figure 15In case 11, the frequency domain resources of the second downlink resource location of the LP-SS (second signal) and the first downlink resource location of the CSI-RS (first signal) are the same, and their time domain resources do not overlap. Furthermore, the LP-SS needs to be sent in the second downlink resource location. In this case, to save network resources, the LP-SS can be omitted and only the CSI-RS can be sent. In this case, the second downlink resource location of the LP-SS can be adjusted so that the frequency domain resources of the adjusted second downlink resource location at least partially overlap (e.g., completely overlap) with the frequency domain resources of the first downlink resource location, and the CSI-RS is sent in the first downlink resource location. The low-power receiver on the terminal can detect the energy of the CSI-RS in the adjusted second downlink resource location. If the energy of the CSI-RS exceeds a first threshold, the information on the OFDM symbol is determined to be bit 1; otherwise, it is determined to be bit 0. The legacy UE receives the CSI-RS in the first downlink resource location and demodulates the CSI-RS normally.

[0198] When there is no overlap between the time domain resources and the frequency domain resources of the first downlink resource position and the second downlink resource position, and it is necessary to send the second signal at the second downlink resource position, the network side device determines to send only the first signal, and adjusts the frequency domain resources of the second downlink resource position according to the fourth frequency domain offset, and adjusts the time domain resources of the second downlink resource position according to the fourth time offset, so that the time domain resources of the first downlink resource position and the time domain resources of the adjusted second downlink resource position at least partially overlap, the frequency domain resources of the first downlink resource position and the frequency domain resources of the adjusted second downlink resource position at least partially overlap, and determines to send the first signal at the first downlink resource position.

[0199] Please refer to Figure 15In case 12, the frequency domain resources and time domain resources of the second downlink resource location of the LP-SS (second signal) and the first downlink resource location of the CSI-RS (first signal) do not overlap, and the LP-SS needs to be sent in the second downlink resource location. In this case, to save network resources, the LP-SS can be omitted and only the CSI-RS can be sent. In this case, the second downlink resource location of the LP-SS can be adjusted so that the frequency domain resources of the adjusted second downlink resource location at least partially overlap (e.g., completely overlap) with the frequency domain resources of the first downlink resource location, and the CSI-RS is sent in the first downlink resource location. The low-power receiver on the terminal can detect the energy of the CSI-RS in the adjusted second downlink resource location. If the energy of the CSI-RS exceeds a first threshold, the information on the OFDM symbol is determined to be bit 1, otherwise it is determined to be bit 0. The legacy UE receives the CSI-RS in the first downlink resource location and demodulates the CSI-RS normally.

[0200] In some embodiments, optionally, the signal sending method also includes: the network side device sends second indication information, the second indication information is used to indicate the second frequency domain offset, or, indicate the second time offset, or, indicate the fourth time offset and the fourth frequency domain offset.

[0201] In some embodiments, optionally, the network-side device may also directly indicate the adjusted second downlink resource position (ie, the fourth downlink resource position) to the terminal.

[0202] In some embodiments, optionally, the second frequency domain offset is agreed upon by a protocol.

[0203] In some embodiments, optionally, the second time offset is agreed upon by a protocol.

[0204] In some embodiments, optionally, the fourth time offset and the fourth frequency domain offset are agreed upon by a protocol.

[0205] In some embodiments, optionally, the network side device sends the first signal at the first downlink resource location and sends the second signal at the second downlink resource location, that is, the low-power signal and the NR downlink signal are respectively sent at their respective downlink resource locations, and there is no need to adjust the downlink resource locations of the low-power signal and the NR downlink signal.

[0206] It should be noted that the network-side device can determine whether it is necessary to adjust at least one of the following items: the time domain / frequency domain position of the first signal and the time domain / frequency domain position of the second signal, based on whether the difference between the time domain / frequency domain positions of the first signal and the second signal is within a preset difference range. If the difference between the time domain / frequency domain positions of the first signal and the second signal is large and exceeds the preset difference range, the time domain / frequency domain positions of the first signal and the second signal are not adjusted to avoid causing problems such as delays. If the difference between the time domain / frequency domain positions of the first signal and the second signal does not exceed the preset interpolation range, it is determined that the time domain / frequency domain positions of the first signal and the second signal can be adjusted.

[0207] It should be noted that the low-power signal in the above embodiments of the present application may be an OOK-1 signal.

[0208] The signal sending method and signal receiving method of the present application are described below with examples in conjunction with specific application scenarios.

[0209] Example 1 of this application:

[0210] In the embodiment of the present application, the second signal (low power signal) takes LP-SS as an example, and the first signal (NR downlink signal) takes CSI-RS as an example.

[0211] like Figure 16 As shown in the figure, when CSI-RS and LP-SS are in different frequency domain positions of the same OFDM symbol or different OFDM symbol positions in the same frequency domain or different OFDM symbol positions in different frequency domains, the network side device in the relevant scheme needs to send signals twice, that is, send CSI-RS to legacy UE (such as UE without LP-WUR) and send LP-SS (OOK signal) to UE with LP-WUR, which results in large network side overhead.

[0212] Considering that the UE with LP-WUR detects the OOK signal, it only needs to detect whether there is energy in the current OFDM symbol. If there is energy, it is bit 1, and if there is no energy, it is bit 0.

[0213] One way to reduce network-side overhead is to overlap the LP-SS transmission location (time-frequency) with the CSI-RS transmission location (time-frequency). In this way, only the CSI-RS signal needs to be transmitted. The legacy UE demodulates the CSI-RS signal normally, and the UE with LP-WUR detects whether there is energy at the current time-frequency location.

[0214] Optionally, sending only the CSI-RS signal may be implemented by at least one of the following methods:

[0215] 1) Adjust the CSI-RS transmission position:

[0216] 1.1) Delay or advance the transmission of CSI-RS to align its time domain position with the time domain position of LP-SS. Figure 16 The second case;

[0217] 1.2) Adjust the frequency domain position of CSI-RS to align with the frequency domain position of LP-SS, Figure 16 The first case;

[0218] 1.3) Simultaneously adjust the time domain position and frequency domain position of CSI-RS to align the time-frequency position and frequency domain position of LP-SS. Figure 16 The third case.

[0219] 2) Adjust the LP-SS transmission position:

[0220] 2.1) Delay or advance the transmission of LP-SS so that its time domain position is aligned with the time domain position of CSI-RS. Figure 16 The second case;

[0221] 2.2) Adjust the frequency domain position of LP-SS to align with the frequency domain position of CSI-RS. Figure 16 The first case;

[0222] 2.3) Simultaneously adjust the time domain position and frequency domain position of LP-SS and align the time-frequency position and frequency domain position of CSI-RS.

[0223] Figure 16 The third case.

[0224] The adjusted time domain offset and frequency domain offset may be predefined, agreed upon by a protocol, or indicated by a network, thereby adjusting the receiving position of the terminal for the first signal.

[0225] It should be noted that the network-side device can determine whether to adjust at least one of the following items: the time domain / frequency domain position of the CSI-RS and the time domain / frequency domain position of the LP-SS, based on whether the difference between the time domain / frequency domain positions of the CSI-RS and LP-SS is within a preset difference range. If the difference between the time domain / frequency domain positions of the CSI-RS and LP-SS is large and exceeds the preset difference range, the time domain / frequency domain positions of the CSI-RS and LP-SS are not adjusted to avoid causing problems such as delays. If the difference between the time domain / frequency domain positions of the CSI-RS and LP-SS does not exceed the preset interpolation range, it is determined that the time domain / frequency domain positions of the CSI-RS and LP-SS can be adjusted.

[0226] Example 2 of this application:

[0227] Example 1 is a case where CSI-RS and LP-SS occupy one OFDM symbol. Please refer to Figure 17The following describes the case where CSI-RS and LP-SS occupy multiple OFDM symbols. Taking 4 OFDM symbols as an example, it is assumed that the sequence to be sent by LP-SS in the time domain is 1011.

[0228] Before adjustment: The frequency domain transmission positions of LP-SS and CSI-RS overlap. In the time domain, LP-SS is sent on OFDM symbols 1 / 3 / 4, and CSI-RS is sent on symbols 1 / 2. Legacy UEs receive and demodulate CSI-RS normally. UEs with LP-WUR detect LP-SS on OFDM symbols 1 / 3 / 4 and CSI-RS energy on OFDM symbol 2. The resulting demodulated sequence is 1111, resulting in demodulation errors.

[0229] After adjustment: CSI-RS is transmitted in OFDM symbol 1. The original CSI-RS in OFDM symbol 2 is frequency-shifted to move out of the LP-WUR receiving bandwidth. CSI-RS is then transmitted at the adjusted transmission position. LP-SS signals are transmitted in OFDM symbols 3 / 4. Additional CSI-RS signals can also be introduced into OFDM symbols 3 / 4. Specifically, the introduced CSI-RS is transmitted at the LP-SS transmission position, and LP-SS is no longer transmitted. Legacy UEs receive and demodulate CSI-RS in OFDM symbol 1 and OFDM symbol 2. UEs with LP-WUR detect CSI-RS energy in OFDM symbol 1, 3, and 4, and detect LP-SS in OFDM symbols 3 / 4. The resulting demodulated sequence is 1011.

[0230] At this time, the frequency shift of the CSI-RS on OFDM symbol 2 requires the network side to instruct the legacy UE to adjust the receiving position.
