[0064] For ease of understanding, some of the contents involved in the embodiments of this application are explained below:
[0065] 1. Low power wake up receiver (LP WUR) / wake-up signal (WUS)
[0066] The basic working principle of LP WUR / WUS is that the receiving end includes a first module and a second module. The first module is the main communication module, which is used to receive the communication data transmitted by the sending end and send the communication data. The second module is a low-power module, which is used to receive the low-power wake-up signal (LP-WUS) and low-power synchronization signal (LP-SS) sent by the sending end. 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. It can also provide wake-up link management, such as determining whether to activate / deactivate LP-WUR based on the measurement results and shutting down the main transceiver (MR). As shown in Figure 2, when the first module is not awakened by the second module, it is always in the closed state and does not send or receive data. When downlink data arrives, the second module detects the wake-up signal sent by the sending end, and the wake-up signal contains the terminal information. Then the second module triggers the first module to switch from the closed state to the working state to receive and send data. The second module can be turned on continuously or discontinuously, and can receive a low-power wake-up signal and a low-power synchronization signal when the second module is turned on.
[0067] 2. Low power signal waveform
[0068] Low-power wake-up signals are usually simple on-off keying (OOK), as shown in Figure 3. In this way, the receiver can obtain the wake-up notification through simple energy detection and subsequent possible sequence detection and recognition.
[0069] Since orthogonal frequency division multiplexing (OFDM) is commonly used in existing 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 the ON / OFF state in the time domain. OOK signals can be received using receivers with lower power consumption.
[0070] Furthermore, the OFDM modulation sequence in the 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, as shown in FIG4 .
[0071] Currently, there is no effective method to suppress interference with the same waveform or modulation as the low-power signal.
[0072] The transmission collaboration method, apparatus, and related 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.
[0073] 5 , which is a flow chart of a transmission collaboration method provided in an embodiment of the present application. As shown in FIG5 , the transmission collaboration method includes the following steps:
[0074] Step 101: A first access network device receives first information sent by a second access network device, wherein the first information is used for at least one of the following: requesting collaborative transmission of a low-power signal; and indicating resource information for the second access network device to transmit the low-power signal.
[0075] Step 102: The first access network device cooperates with the second access network device to send a low-power signal.
[0076] Among them, the first information is used to request cooperation in sending low-power signals, which may mean: the first information is used to request cooperation with the second access network device to send low-power signals; or, the first information is used to request the first access network device to cooperate with the second access network device to send low-power signals.
[0077] In addition, resource information can be understood or replaced by collaborative resource information, and the collaborative resource information can refer to resource-related information for collaborating with the second access network device to send low-power signals. For example, the collaborative resource information can include: time domain information; frequency domain information; signal information.
[0078] In one embodiment, the first information may include at least one of third indication information and fourth indication information, the third indication information is used to request the first access network device to cooperate with the second access network device to send a low-power signal, and the fourth indication information indicates resource information for the second access network device to send a low-power signal.
[0079] In addition, the low power consumption signal may include at least one of the following: a low power consumption synchronization signal; a low power consumption wake-up signal.
[0080] In one embodiment, the low-power signal can be a low-power signal of amplitude shift keying (ASK), frequency shift keying (FSK), on-off keying OOK superimposed on orthogonal frequency division multiplexing OFDM or OFDM, so that the embodiment of the present application can solve the problem that the low-power signal based on ASK, FSK, on-off keying OOK superimposed on orthogonal frequency division multiplexing OFDM or OFDM is susceptible to interference signals with the same waveform or modulation, resulting in a high probability of detection failure.
[0081] In one implementation, the first information received by the first access network device may be delivered via an X2 interface message or an Xn interface message, or may be delivered via an S1 interface message or an NG interface message through a core network device.
[0082] For example, the first access network device may receive the first information via an X2 interface or an Xn interface, wherein the first information may be included in an X2 interface message or an Xn interface message and sent to the first access network device.
[0083] In addition, the X2 interface message or Xn interface message may include: setup or response messages, such as capability configuration information exchanged between base stations during initial establishment of the X2 or Xn interface; configuration update or update response (updateACK) messages, such as update and response information when a configuration change occurs; cell activation or response messages; handover preparation messages, handover report messages, or handover update messages; or resource status report messages.
[0084] In an embodiment of the present application, a first access network device receives first information sent by a second access network device, where the first information is used for at least one of the following: requesting collaboration in sending a low-power signal; instructing the second access network device on resource information for sending a low-power signal; or the first access network device cooperating with the second access network device in sending a low-power signal. In this way, the first access network device collaborates with the second access network device in sending a low-power signal based on the first information, thereby increasing the probability of successful detection of the low-power signal sent by the second access network device.
[0085] Optionally, the first access network device cooperates with the second access network device to send a low power consumption signal, including any one of the following:
[0086] The first access network device performs interference avoidance processing on a time domain and frequency domain resource position where the second access network device sends a low power consumption signal;
[0087] or
[0088] The first access network device performs signal enhancement processing at the time domain and frequency domain resource position where the second access network device sends the low power consumption signal.
[0089] Optionally, the first information is used to request the first access network device to cooperate with the second access network device in a first cooperation mode to send a low-power signal; or, the first information is used to request the first access network device to cooperate with the second access network device in a second cooperation mode to send a low-power signal;

[0091] The second collaboration mode includes: performing signal enhancement processing at the time domain and frequency domain resource position where the second access network device sends the low power consumption signal.
[0092] In one embodiment, when the first access network device determines based on the first information that interference avoidance processing is performed at the time domain and frequency domain resource position where the second access network device sends a low power consumption signal, it may not send any signal at the same time domain and frequency domain position as the low power consumption signal, or may not send a signal with the same waveform as the low power consumption signal, or a signal with the same modulation method, at the same time domain and frequency domain position as the low power consumption signal.
[0093] In one embodiment, when the first access network device determines, based on the first information, to perform signal enhancement processing at the time domain and frequency domain resource position where the second access network device sends a low power signal, the low power signal can be sent in an SFN manner. For example, the same low power wake-up signal or low power synchronization signal as the second access network device can be sent in an SFN manner.
[0094] In one embodiment, the first information may indicate interference avoidance transmission to request the first access network device to adopt a first collaborative mode to cooperate with the second access network device to send a low-power signal. In the case where the first information is used to request the first access network device to adopt a first collaborative mode to cooperate with the second access network device to send a low-power signal, the second access network device requests the first access network device to perform an interference avoidance operation on the low-power signal according to the first collaborative resource information, and the interference avoidance operation includes one of the following: not sending a signal with the same waveform or modulation as the low-power signal at the time domain and frequency domain resource position where the low-power signal is sent, or not sending any signal at the time domain and frequency domain resource position where the low-power signal is sent. The first collaborative resource information may refer to the resource information indicated by the first information.
[0095] In one embodiment, the first information may indicate single frequency network (SFN) transmission to request the first access network device to cooperate with the second access network device in sending a low-power signal using a second collaborative mode. The second access network device requests the first access network device to send a low-power signal using an SFN mode based on first collaborative resource information, where the first collaborative resource information may refer to resource information indicated by the first information.
[0096] It should be noted that the collaboration mode can also be described as the collaboration type.
[0097] In this embodiment, the first information indicates that the second access network device requests the first access network device to cooperate with the second access network device to send a low-power signal. The first access network device can cooperate with the second access network device to send a low-power signal in accordance with the cooperation method indicated by the first information, so that the second access network device can participate in the determination of the cooperation method and improve the probability of successful transmission cooperation.
[0098] Optionally, after the first access network device receives the first information sent by the second access network device, the method further includes:
[0099] The first access network device sends second information to the second access network device;
[0100] The second information is used to indicate that the first access network device agrees to cooperate with the second access network device in sending a low-power signal in a first cooperation manner; or, the second information is used to indicate that the first access network device agrees to cooperate with the second access network device in a second cooperation manner to send a low-power signal;
[0101] or,
[0102] The second information is used to instruct the first access network device to cooperate with the second access network device to send resource information of the low-power signal;
[0103] The first cooperation mode includes: performing interference avoidance processing on the time domain and frequency domain resource position where the second access network device sends the low power consumption signal;
[0104] The second collaboration mode includes: performing signal enhancement processing at the time domain and frequency domain resource position where the second access network device sends the low power consumption signal.
[0105] Among them, the first access network device can determine, based on its own capabilities, whether to adopt the first collaboration mode or the second collaboration mode to cooperate with the second access network device to send a low-power signal; or, the first access network device can determine, based on its own capabilities, the resource information for the first access network device to cooperate with the second access network device to send a low-power signal.
[0106] The second message may be delivered via an X2 interface message or an Xn interface message, or delivered via an S1 interface message or an NG interface message through a core network device.
[0107] In this embodiment, the second information indicates the collaboration mode of the first access network device cooperating with the second access network device to send low-power signals, so that the second access network device can obtain the collaboration mode of the first access network device cooperating with the second access network device to send low-power signals; or, the second information indicates the resource information of the first access network device cooperating with the second access network device to send low-power signals, so that the second access network device can obtain the resource information that the first access network device can cooperate with according to the resource information indicated by the second information.
[0108] Optionally, the performing interference avoidance processing on the time domain and frequency domain resource position where the second access network device sends the low power consumption signal includes any one of the following:
[0109] Not sending a signal with the same waveform at the time domain and frequency domain resource position where the second access network device sends the low power consumption signal; or not sending a signal with the same modulation mode at the time domain and frequency domain resource position where the second access network device sends the low power consumption signal;
[0110] No signal is sent at the time domain and frequency domain resource position where the second access network device sends the low power consumption signal.
[0111] Among them, the modulated signal may include an ASK signal, an FSK signal, an on-off keying OOK superimposed orthogonal frequency division multiplexing OFDM or OFDM signal, etc. Not sending a signal with the same modulation mode at the time domain and frequency domain resource position where the second access network device sends a low-power signal can be understood as not sending a modulated signal with the same modulation type as the low-power signal sent by the second access network device at the time domain and frequency domain resource position where the second access network device sends a low-power signal. Taking the low-power signal sent by the second access network device as an ASK signal as an example, not sending a signal with the same modulation mode at the time domain and frequency domain resource position where the second access network device sends a low-power signal can mean that the ASK signal is not sent at the time domain and frequency domain resource position where the second access network device sends a low-power signal.
[0112] It should be noted that, when the first information is also used to indicate resource information for the second access network device to send a low-power signal, the time-domain and frequency-domain resource location for the second access network device to send the low-power signal can be determined by the resource information indicated by the first information. For example, the time-domain and frequency-domain resource location for the second access network device to send the low-power signal can be the time-domain and frequency-domain resource location represented by the time-domain information and frequency-domain information indicated by the first information.
[0113] In this embodiment, the signal of the same waveform is not sent at the time domain and frequency domain resource position where the second access network device sends the low power consumption signal, thereby avoiding the low power consumption signal sent by the second access network device from being affected by the signal of the same waveform, thereby increasing the probability of the receiving end of the low power consumption signal successfully detecting the low power consumption signal.
[0114] In this embodiment, the signal with the same modulation mode is not sent at the time domain and frequency domain resource position where the second access network device sends the low power signal, thereby avoiding the low power signal sent by the second access network device from being affected by the same modulation signal, thereby increasing the probability of the receiving end of the low power signal successfully detecting the low power signal.
[0115] In this embodiment, no signal is sent at the time domain and frequency domain resource position where the second access network device sends the low power consumption signal, thereby avoiding the low power consumption signal sent by the second access network device from being affected by the interference signal, thereby increasing the probability of the receiving end of the low power consumption signal successfully detecting the low power consumption signal.
