[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on December 15, 2023, with application number 202311735677.5 and application name "A Communication Method and Device", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of wireless communication technology, and in particular to a communication method and device. Background Art

[0004] In R18, the 3rd Generation Partnership Project (3GPP) conducted research on low power (LP) wake-up signals (WUS) with the aim of evaluating the potential for reducing power consumption of terminals equipped with low power radios (LR). Generally speaking, even if a terminal does not send or receive any data, it consumes tens of milliwatts of power, which is called idle power consumption. This idle power consumption is caused by the fact that the terminal must periodically measure and detect potential LP-WUS. Among them, LR will periodically measure and detect LP-WUS, and the main radio (MR) can be turned off when LR is active and searching for potential LP-WUS signals. LR can wake up MR to send and receive data when LP-WUS is detected.

[0005] However, each time the MR is turned on and off, additional energy is consumed. The MR's power amplifier (PA) requires a power ramp when it is turned on, which results in a certain delay and additional power consumption as the power transitions from zero to a steady state. Therefore, frequently waking up the MR is unlikely to achieve energy savings.

[0006] Summary of the Invention

[0007] The present application provides a communication method and apparatus to reduce the power consumption of terminal equipment.

[0008] In a first aspect, a communication method is provided. The method can be performed by a first communication device or a chip / chip system. The first communication device can be a network device or a terminal device. In the method, the first communication device includes a first module and a second module, and the power consumption of the first module is lower than the power consumption of the second module. The first communication device receives a low-power wake-up signal, and the low-power wake-up signal indicates a function to be executed by the first module. The first communication device activates the first module and executes the function.

[0009] Based on the above scheme, the function of the first module is indicated by a low-power wake-up signal, so the terminal can wake up the first module to perform the corresponding function. Compared with the related technology in which all functions are performed by the second module, the number of times the second module is woken up can be reduced, so frequent waking up of the second module can be avoided, thereby achieving the purpose of energy saving.

[0010] In a second aspect, a communication method is provided. The method can be performed by a second communication device or a chip / chip system. The second communication device can be a network device or a terminal device. In this method, the second communication device determines a low-power wake-up signal, where the low-power wake-up signal indicates a function performed by a first module included in the communication device, where the power consumption of the first module is lower than the power consumption of a second module included in the communication device. The second communication device sends the low-power wake-up signal to the communication device.

[0011] In a possible implementation manner of the first aspect and the second aspect, the functions include one or more of the following: channel state information measurement, radio resource management measurement, small data transmission, and sensing or updating radio frequency channel data RF-map.

[0012] Based on the above solution, the first module has a simple structure, low data processing latency, and low power consumption, making it suitable for use in small data transmission scenarios with low data volume and insensitivity to latency. In addition, the channel state information measurement and radio resource management measurement functions can detect measurement signals on part of the bandwidth or detect measurement signals received by part of the antenna ports. Therefore, they can be performed through the first module to achieve energy conservation. For sensing or updating RF channel data, this can be achieved by measuring linear signals, such as chirp signals. Therefore, it can be performed through the first module to reduce the energy consumption of the communication device.

[0013] In a possible implementation of the first and second aspects, the function includes perception, and the low-power wake-up signal further indicates one or more of the following: a waveform of the perception signal, a waveform of a reported perception result, a number of time-domain resource perceptions of the perception signal, or a time of reporting the perception result.

[0014] Based on the above solution, when the low-power wake-up signal indicates that the function of the first module includes perception, the low-power wake-up signal can also indicate the configuration information of the perception, so that the terminal can wake up the first module and perform perception based on the perception configuration information.

[0015] In a possible implementation manner of the first aspect and the second aspect, the waveform of the perception signal includes a chirp signal or an orthogonal frequency division multiplexing (OFDM) signal.

[0016] This solution uses chirp linear modulation signals, making processing simple at both the transmitter and receiver, while also reducing power consumption and providing high-resolution perception of the environment and target location, speed, and texture. OFDM's high power and wide coverage ensure highly accurate perception results.

[0017] In a possible implementation manner of the first aspect and the second aspect, the function includes radio resource management measurement, and the low power consumption wake-up signal further indicates one or more of the following: a measured signal format or a measurement rule.

[0018] Based on this solution, when the low-power wake-up signal indicates that the function of the first module includes wireless resource management measurement, the low-power wake-up signal can also indicate the configuration information of the wireless resource management measurement, and the terminal can wake up the first module to perform wireless resource management measurement based on the configuration information.

[0019] In one possible implementation of the first and second aspects, the measured signal format includes a low-power synchronization signal or a synchronization signal block (SSB). Based on this solution, the SSB is relatively complex, so a more accurate detection result can be obtained, while the low-power synchronization signal can simplify the SSB format, allowing it to be sent and measured with less power.

[0020] In a possible implementation manner of the first aspect and the second aspect, the measurement rule includes relaxed measurement or normal measurement. Based on this solution, the LP-WUS may indicate a measurement rule for an SSB or a low power synchronization signal.

[0021] In a possible implementation of the first and second aspects, the measurement rule includes relaxed measurement, and the low-power wake-up signal further indicates the number of measurements, the measurement period, the length of the measurement window, or the starting position of the measurement window. Based on this solution, the low-power wake-up signal can indicate measurement configuration information of the SSB or the low-power synchronization signal, and the terminal can wake up the first module to measure based on the measurement configuration, and receive and measure the SSB or the low-power synchronization signal.

[0022] In a possible implementation manner of the first aspect and the second aspect, the radio resource management measurement includes neighboring cell measurement, and the low-power wake-up signal further indicates the number of neighboring cells associated with the cell where the terminal device is located.

[0023] Based on this solution, for neighbor cell measurements, the low-power wake-up signal indicates the number of neighbor cells associated with the terminal's cell, or in other words, the size of the list of neighbor cells associated with the terminal's cell requiring radio resource management measurements. A larger number of neighbor cells indicates a larger radio resource management measurement list, providing more options for switching cells. A smaller number of neighbor cells indicates a smaller radio resource management measurement list, resulting in fewer radio resource management measurements and better energy savings.

[0024] In a possible implementation manner of the first aspect and the second aspect, the low-power wake-up signal indication function includes perception and radio resource management measurement, and the low-power wake-up signal further indicates that the measured waveform is a chirp signal.

[0025] Based on this solution, the perception function and the wireless resource management measurement function are both received by the first module and the signal is measured. Therefore, the low-power wake-up signal can instruct the first module to simultaneously perform the perception function and the wireless resource management measurement function, which can reduce the overhead of the perception signal and the wireless resource management measurement signal, and can also avoid the energy consumption caused by the terminal receiving the signal multiple times and making multiple measurements. The power of chirp is small, so the energy consumption is low, which can further reduce the energy consumption of the terminal.

[0026] In a third aspect, a communication device is provided, comprising: a processing unit and a transceiver unit. The transceiver unit is configured to receive a low-power wake-up signal, the low-power wake-up signal indicating a function to be executed by a first module. The processing unit is configured to activate the first module to execute the function.

The transceiver unit is configured to send the low-power wake-up signal to the first communication device.

[0028] In a possible implementation manner of the third aspect and the fourth aspect, the functions include one or more of the following: channel state information measurement, wireless resource management measurement, small data transmission, and sensing or updating radio frequency channel data RF-map.

[0029] In a possible implementation of the third and fourth aspects, the function includes perception, and the low-power wake-up signal further indicates one or more of the following: the waveform of the perception signal, the waveform of the reported perception result, the number of time domain resource perceptions of the perception signal, or the time of reporting the perception result.

[0030] In a possible implementation manner of the third aspect and the fourth aspect, the waveform of the perception signal includes a chirp signal or an orthogonal frequency division multiplexing (OFDM) signal.

[0031] In a possible implementation manner of the third aspect and the fourth aspect, the function includes radio resource management measurement, and the low-power wake-up signal further indicates one or more of the following: a measured signal format or a measurement rule.

[0032] In a possible implementation manner of the third aspect and the fourth aspect, the measured signal format includes a low-power synchronization signal or a synchronization signal block.

[0033] In a possible implementation manner of the third aspect and the fourth aspect, the measurement rule includes relaxed measurement or normal measurement.

[0034] In a possible implementation manner of the third and fourth aspects, the measurement rule includes relaxed measurement, and the low-power wake-up signal further indicates the number of measurements, the measurement cycle, the length of the measurement window, or the starting position of the measurement window.

[0035] In a possible implementation manner of the third aspect and the fourth aspect, the radio resource management measurement includes neighboring cell measurement, and the low-power wake-up signal further indicates the number of neighboring cells associated with the cell where the terminal device is located.

[0056] In order to facilitate understanding of the technical solutions provided by the embodiments of the present application, the technical terms involved in the embodiments of the present application are explained and illustrated below.

[0057] 1) Low power wake up signal (LP-WUS), which is used in multiple low power communication protocols, such as long range radio (LoRa), Bluetooth or wireless fidelity (WiFi). LP-WUS allows the design and implementation of low power receivers, which helps reduce device power consumption. LP-WUS is very similar to WUS. WUS is based on the traditional Zadoff-Chu (ZC) sequence and downlink control information (DCI) in formats 2-6 in the physical downlink control channel (PDCCH). If WUS is detected, the device will continue to decode the paging message, otherwise it will return to sleep and wait for the next opportunity to receive WUS.

[0058] The technical solutions of the embodiments of the present application can be applied to New Radio (NR) systems, Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Worldwide Interoperability for Microwave Access (WiMAX) communication systems, and fifth generation communication systems (5G) and 5G th generation, 5G), and next-generation wireless communication systems, such as 6G, are not restricted here.

[0059] FIG1 is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. As shown in FIG1 , the communication system includes a wireless access network 100. The wireless access network 100 may include at least one network device (such as 110a and / or 110b in FIG1 ) and may also include at least one terminal device (such as at least one of 120a-120j in FIG1 ). The terminal device is connected to the access network device wirelessly, and the access network device is connected to the core network device wirelessly or by wire. Terminal devices and network devices may be connected to each other by wire or by wireless. FIG1 is only a schematic diagram, and the communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in FIG1 .

[0060] A network device is a network-side device with wireless transceiver capabilities. A network device can be a device in a radio access network (RAN) that provides wireless communication capabilities for terminal devices, and is called a RAN device. For example, a network device can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a fifth-generation (5G) mobile communication system, a next-generation base station in a sixth-generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. It can also be a module or unit that performs some of the functions of a base station, such as a centralized unit (CU) or a distributed unit (DU). The CU here completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete the functions of part of the physical layer or all of the physical layer. For the specific description of the above-mentioned protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP). The network device can be a macro base station (such as 110a in Figure 1), a micro base station or an indoor station (such as 110b in Figure 1), a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network device.

[0061] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes implement part of the functions of the base station respectively. For example, the RAN node can be a CU, DU, CU-control plane (CP), CU-user plane (UP), or radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0062] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (ORAN) system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application takes CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0063] A terminal device is a user-side device with wireless transceiver capabilities. A terminal device may also be referred to as user equipment (UE), a mobile station, a mobile terminal, etc. Terminal devices can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. The terminal device may be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home appliance, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device.

[0064] Network devices and terminal devices can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; on water; and in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of network devices and terminal devices.

[0065] The roles of network devices and terminal devices can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile network device. To terminal devices 120j accessing the wireless access network 100 via 120i, terminal device 120i is a network device. However, to network device 110a, 120i is a terminal device, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via an interface protocol between network devices. In this case, 120i is also a network device relative to 110a. Therefore, both network devices and terminal devices can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be referred to as communication devices with network device functionality, while 120a-120j in Figure 1 can be referred to as communication devices with terminal device functionality.

[0066] In the embodiments of the present application, the functions of the network device may also be performed by a module (such as a chip) in the network device, or by a control subsystem that includes the network device function. The control subsystem that includes the network device function here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of the terminal device may also be performed by a module (such as a chip or a modem) in the terminal device, or by a device that includes the terminal device function. In the following, the example in which the terminal device function is performed by the terminal and the network device function is performed by the base station is described.

[0067] With the development of 5G technology, 5G networks are placing increasingly higher demands on terminal capabilities. This increased demand for terminal capabilities necessitates a corresponding increase in terminal hardware, which inevitably increases terminal power consumption. Compared to LTE terminals, 5G terminals support a maximum power of 29dBm. Under typical services, such as comprehensive web browsing, instant messaging, gaming, or food consumption, 5G terminal communication power consumption increases by an average of over 200% compared to LTE terminals. Terminal battery life is a crucial aspect of user experience and impacts the suitability of 5G terminals or services. Therefore, ensuring the battery life of 5G terminals faces significant challenges, and research on how to reduce 5G terminal power consumption is key to addressing this issue.

[0068] Referring to Figure 2, the terminal may include a low power wake up radio (LR) and a main radio (MR). It will be understood that the LR and MR may be integrated as logical function modules on the same processor (e.g., a chip), or the LR and MR may be independent processors (e.g., chips). The power consumption of the LR is lower than that of the MR. In another example, the bandwidth of the LR is also lower than that of the MR. It should be noted that MR and LR are shown only as exemplary names, the LR may also be referred to as an auxiliary module, and the MR may also be referred to as a main module, which is not specifically limited in this application. In the embodiment of the present application, the LR is taken as the first module and the MR is taken as the second module as an example for illustration.

[0069] In R18, the 3rd generation partnership project (3GPP) conducted research on low power (LP) wake-up signals (WUS) with the aim of evaluating the potential for reducing power consumption in 5G terminals equipped with low LR. Generally speaking, even if a 5G terminal does not send or receive any data, it consumes tens of milliwatts of power, which is called idle power consumption. This idle power consumption is caused by the fact that the 5G terminal must periodically measure and detect potential LP-WUS. Among them, LR will periodically measure and detect LP-WUS, and MR can be turned off when LR is active and searching for potential LP-WUS signals. LR can wake up MR to send and receive data when LP-WUS is detected.

[0070] However, each time the MR is turned on and off, additional energy is consumed. The power amplifier (PA) of the MR is turned on with a power ramp, which brings a certain delay and additional power consumption when the power changes from zero to a stable state. For example, when performing radio resource management (RRM) measurements, the LR can receive LP-WUS and wake up the MR to perform RRM measurements. After the measurement is completed, the MR can go to sleep. For another example, after the LR receives LP-WUS, it can wake up the MR to receive and demodulate the signal. In these processes, waking up the MR will generate additional power consumption. Therefore, it is difficult to achieve energy saving by frequently waking up the main module.

[0071] In view of this, an embodiment of the present application provides a communication method. In this method, the LP-WUS indicates the function to be executed by the LR, so that the terminal can wake up the LR and execute the corresponding function. Compared with the related art in which all functions are executed by the MR, the number of times the MR is woken up can be reduced, thereby avoiding frequent MR wake-ups and achieving energy saving.

[0072] Referring to Figure 3, which is an exemplary flow chart of a communication method provided in an embodiment of the present application, the method may include the following operations. In the embodiment shown in Figure 3, the first communication device may include a first module and a second module, and the power consumption of the first module is lower than the power consumption of the second module. In the embodiment shown in Figure 3, the first communication device is a terminal and the second communication device is a base station.

[0073] S301: The base station sends a low-power wake-up signal to the terminal.

[0074] Correspondingly, the terminal receives a low-power wake-up signal from the base station.

[0075] The low-power wake-up signal indicates the function of the first module. For example, the low-power wake-up signal may carry first indication information (indicator), and the first indication information indicates the function of the first module. In an embodiment of the present application, the low-power wake-up signal can be received by a low-power receiver, which helps to reduce the power consumption of the device. The following description takes the low-power wake-up signal being LP-WUS as an example.

[0076] S302: The terminal activates the first module and executes the function.

[0077] The terminal may receive an LP-WUS, for example, by receiving the LP-WUS through a first module and demodulating the LP-WUS to obtain information carried by the LP-WUS. For example, the terminal may demodulate the LP-WUS to obtain first indication information carried by the LP-WUS and activate the first module based on the first indication information to execute the function indicated by the first indication information.

[0078] It can be understood that activating the first module can be understood as turning on the first module or waking up the first module, which is essentially executing the function indicated by the LP-WUS through the first module.

[0079] The following describes the function of the first module indicated by the first indication information carried by the LP-WUS in conjunction with Table 1.

[0080] Table 1: Example of first indication information indicating the function of the first module

[0081] In Table 1, when the first indication information takes a value of 0, it can indicate that the channel state information measurement function of the first module is activated (or turned on). Activating the channel state information measurement function of the first module can be understood as activating the function of the first module to receive the channel state information (CSI) reference signal (RS) and activating the physical uplink control channel (PUCCH) transmission function of the first module. The first module can send a channel quality indication (continuous quality improvement, CQI) based on the CSI-RS measurement result to the base station through the PUCCH. Although the structure of the first module is simple, the first module can complete the CSI-RS measurement and the PUCCH transmission function, which can save the power consumption of the terminal compared to the second module performing the channel state information measurement function.

[0082] When the value of the first indication information is 1, it can indicate that the RRM measurement function of the first module is activated (or turned on). Activating the radio resource management (RRM) measurement function of the first module can be understood as activating the function of the first module to receive signals from neighboring cells and activating the PUCCH transmission function of the first module. Although the structure of the first module is simple, the first module can complete the signal measurement of the neighboring cells and the PUCCH transmission function, which can save the power consumption of the terminal compared to the RRM measurement function performed by the second module.

[0083] When the value of the first indication information is 2, it indicates that the small data transmission function of the first module is activated (or turned on). The first module has a simple structure, high data processing latency, and low power consumption. Therefore, it is suitable for use in small data transmission (SDT) scenarios with low data volume and insensitivity to latency. Therefore, the first indication information can be set to 2 to instruct the terminal to activate the first module to send or receive data.

[0084] In Table 1, activating the perception function of the first module can be understood as activating (or turning on) the function of the first module to receive the perception signal and send the perception result. Activating the function of the first module to update the RF-map can be understood as activating (or turning on) the function of the first module to receive the perception signal and process it to obtain the RF-map. In this embodiment of the present application, the RF-map can indicate the following two aspects of information:

[0085] On the one hand, RF-map corresponds to a certain geographical area and is used to indicate the geographical location and size of multiple areas divided within the geographical area. On the other hand, RF-map can indicate the channel quality prediction value of each area in the multiple areas. The geographical area can be an area of ​​a certain range in the real physical world. The multiple areas can be areas obtained by dividing the geographical area in a certain way. In this application, different areas have the same shape, outline, size, radius, and area. Different areas have different geographical locations. There is no overlap between different areas.

[0086] In one possible scenario, the LP-WUS may indicate a function listed in Table 1. The terminal may activate the first module to execute the function indicated by the LP-WUS. In another possible scenario, the LP-WUS may indicate multiple functions listed in Table 1. The terminal may activate the first module and execute the multiple functions one by one according to the LP-WUS instructions.

[0087] It is understandable that the correspondence between the first indication information and the function of the first module shown in Table 1 is only shown as an example and does not constitute a limitation on the correspondence. In addition, the value of the first indication information in Table 1 is also shown as an example. In the embodiment of the present application, the first indication information can also indicate the function of the first module by indicating a function identifier or the like. The indication information below, such as the second indication information, the third indication information, etc., are also shown as examples and will not be described again.

[0088] The following description will be made by taking the example of the LP-WUS instructing the first module to perform the sensing function and the RRM measurement function. The LP-WUS may also indicate the configuration information of the sensing or the configuration information of the RRM measurement.

[0089] In one possible implementation, the LP-WUS instructs the first module to perform a sensing function. Sensing, a key concept in 5G and 6G, is typically deployed alongside cellular networks and has two modes: autonomous transmission and self-reception, and autonomous transmission and reception by others. The base station can instruct the first module to perform sensing via the LP-WUS.

[0090] When LP-WUS instructs the first module to perform the perception function, LP-WUS may indicate one or more of the waveform of the perception signal, the waveform of the reported perception result, the time domain resource of the perception signal, the number of perceptions, or the time of reporting the perception result, which are introduced below.

[0091] In one example, the LP-WUS can indicate the time domain resources of the perception signal. Referring to Figure 4A , the LP-WUS carries the time domain resource indication K3, which refers to the time interval from receiving the LP-WUS to performing the perception. The LP-WUS can also indicate the perception interval T1, which refers to the interval between two perception signals. The LP-WUS can also indicate the number of perceptions n, where n is an integer greater than or equal to 1. The base station indicates the number of perceptions n through the LP-WUS, and the terminal can determine the number of perception signals. Using the LP-WUS indication K3 and the perception interval T1, the terminal can determine the time domain resources of each perception signal, thereby activating the first module and accurately receiving the perception signal.

[0092] After the first module receives n sensing signals, it can provide feedback on the sensing results via an uplink channel, such as the PUCCH. In another example, the LP-WUS can indicate the time domain resource for the sensing results. The terminal can then transmit a PUCCH using the time domain resource for the sensing results via the first module, carrying the sensing results. Referring to Figure 4B , the LP-WUS can indicate the time domain resource K4 for the sensing results. K4 indicates the time interval between receiving the LP-WUS and transmitting the sensing results.

[0093] It is understandable that the table of K4 can be a newly defined time domain resource, which can be shown with reference to the table of uplink scheduling K2 in the related art. Alternatively, the table of K4 can reuse the table of uplink scheduling K2 in the related art, except that the table of K4 is smaller than the table of K2.

[0094] In another example, the LP-WUS may indicate the waveform of the perception signal. For example, the LP-WUS may carry second indication information, and the second indication information may indicate the waveform of the perception signal. This is described below in conjunction with Table 2.

[0095] Table 2: Example of a waveform of a perception signal indicated by the second indication information

[0096] In Table 2, if the second indication information value is 0, the waveform of the perception signal can be indicated as a chirp, and the chirp signal's frequency and slope carry information. Because chirp signals are linearly modulated, processing at the transmitter and receiver is simple, power consumption is low, and resolution is high for sensing the environment and target location, velocity, and texture.

[0097] When the value of the second indication information is 1, it can indicate that the waveform of the sensing signal is OFDM. OFDM signal coverage is strong, so a more accurate sensing result can be obtained, and a traditional transceiver can also be reused.

[0098] It should be noted that the manner in which the second indication information shown in Table 2 indicates the waveform of the perception signal is shown only as an example. Alternatively, when the value of the second indication information is 1, it may indicate that the waveform of the perception signal is a chirp, and when the value of the second indication information is 0, it may indicate that the waveform of the perception signal is OFDM. The second indication information may be newly added indication information, or may reuse existing fields in the LP-WUS, and this application does not impose any specific limitations.

[0099] In another example, the LP-WUS may report the waveform of the sensing result. For example, the LP-WUS may carry third indication information, and the third indication information may indicate the waveform of the sensing result to be reported. This is described below in conjunction with Table 3.

[0100] Table 3: Example of a waveform of a perception signal indicated by the third indication information

[0101] In Table 3, when the value of the third indication information is 0, the waveform used to report the perception result may be a chirp. When the value of the third indication information is 1, the waveform used to report the perception result may be OFDM. Chirps have low transmission power and low energy consumption, so using chirps to carry perception results can save power consumption in terminals. OFDM, on the other hand, has high power and strong coverage, thus increasing the likelihood that perception results will be received.

[0102] It should be noted that the manner in which the third indication information shown in Table 3 indicates the waveform for reporting the perception result is shown only as an example. Alternatively, when the value of the third indication information is 1, the waveform indicating that the perception result is reported is a chirp, and when the value of the third indication information is 0, the waveform indicating that the perception result is reported is OFDM. The third indication information may be newly added indication information, or may reuse existing fields in the LP-WUS, and this application does not impose any specific limitations.

[0103] It is understandable that the second indication information and the third indication information can be designed as one indication information, such as the fourth indication information, which jointly indicates the waveform of the sensing result and the waveform of the reporting sensing result.

[0104] Table 4: Example of a fourth indication information

[0105] As shown in Table 4, the fourth indication information can be used to jointly indicate the waveform of the perception signal and the waveform of the perception result reported. Assuming that the fourth indication information is 2 bits and the value of the fourth indication information is 0, it can indicate that the waveform of the perception signal is a chirp and the waveform of the perception result reported is OFDM. If the value of the fourth indication information is 1, it can indicate that the waveform of the perception signal is a chirp and the waveform of the perception result reported is a chirp, and so on.

[0106] It should be noted that the fourth indication information shown in Table 4 indicates the waveform of the perception result and the manner in which the waveform of the perception result is reported, which is shown only as an example. The fourth indication information may be newly added indication information, or may reuse existing fields in the LP-WUS, and this application does not make specific limitations.

[0107] Based on the above solution, the base station indicates the perception configuration information through LP-WUS and instructs the first module to perform the perception function. After receiving the LP-WUS, the terminal can obtain the perception configuration information and activate the first module to perform the perception function based on the configuration information.

[0108] In another possible implementation, the LP-WUS instructs the first module to perform RRM measurement functions. For example, the LP-WUS may instruct the first module to perform cell measurement and / or neighboring cell measurement functions.

[0109] When the LP-WUS instructs the first module to perform the RRM measurement function, the LP-WUS may indicate the type of measurement signal. For example, the LP-WUS may indicate the use of the LP-synchronization signal (SS) to complete the measurement, or indicate the use of SSB to complete the measurement. Exemplarily, the LP-WUS may include fifth indication information, and the fifth indication information may indicate the use of LP-SS to complete the measurement or indicate the use of SSB to complete the measurement. Assuming that the fifth indication information is 1-bit indication information, when the value of the fifth indication information is 0, it may indicate the use of LP-SS to complete the measurement, and when the value of the fifth indication information is 1, it may indicate the use of SSB to complete the measurement. Conversely, when the value of the fifth indication information is 1, it may indicate the use of LP-SS to complete the measurement, and when the value of the fifth indication information is 0, it may indicate the use of SSB to complete the measurement.

[0110] Unlike the related art in which radio resource control (RRC) is used to configure reference signals such as SSB to complete RRM measurement, the above-mentioned solution of the present application can use LP-SS to complete RRM measurement through LP-WUS indication, which can simplify the format of SSB and use less power for transmission and measurement.

[0111] In one example, the LP-WUS may indicate measurement rules for RRM measurements. For example, the LP-WUS may carry sixth indication information, which may indicate whether the RRM measurement rules use normal measurement rules or relaxed measurement rules. Referring to FIG5A , relaxed measurement rules allow SSB or LP-SS to be performed within a larger timing configuration window, thereby reducing the number of measurements and achieving energy conservation.

[0112] In an embodiment of the present application, LP-WUS may indicate the position of the timing configuration window for RRM measurement, such as indicating the length and starting position of the timing configuration window. Referring to Figure 5B, the terminal may activate the first module to complete the measurement of SSB or LP-SS based on the starting position and length of the timing configuration window indicated by LP-WUS. If SSB is used to complete the measurement, the first module will detect the power and beam of SSB within the timing configuration window (SMTC) and continue the detection within the next identical timing configuration window. If LP-SS is used to complete the measurement, the first module will detect the power and beam of LP-SS within the timing configuration window and continue the detection within the next identical timing configuration window.

[0113] In another example, the LP-WUS may indicate the number of measurements and the measurement period. The terminal may determine the number of times the timing configuration window appears and the interval between each timing configuration window according to the number of measurements indicated and the measurement period indicated, and perform measurements on the LP-SS or SSB.

[0114] In the related art, there is no end condition for SSB measurement. In an embodiment of the present application, LP-WUS can indicate the end condition of the RRM measurement, such as the threshold value of the measurement result, and the terminal can stop the measurement when the measurement result reaches the threshold value. For another example, LP-WUS can indicate the end time of the RRM measurement. For example, LP-WUS can indicate the end time point of the RRM measurement, or LP-WUS can indicate the timing duration of the timer (timer). After the timing duration is reached, it can indicate that the end time of the RRM measurement has been reached, and the terminal can stop the measurement.

[0115] In the embodiment of the present application, for neighbor cell measurement, the LP-WUS indicates the number of neighbor cells associated with the terminal's cell, or in other words, the LP-WUS indicates the size of the list of neighbor cells associated with the terminal's cell that require RRM measurement. A larger number of neighbor cells indicates a larger RRM measurement list, which provides more options for switching cells. A smaller number of neighbor cells indicates a smaller RRM measurement list, which reduces the number of RRM measurements and improves energy conservation.

[0116] In one possible implementation, the LP-WUS may instruct the first module to simultaneously perform a perception function and an RRM measurement function, and the LP-WUS may indicate that the perception signal (measurement signal) is a chirp. In this method, the perception function and the RRM measurement function are both performed by the first module receiving and measuring the signal. Therefore, the LP-WUS may instruct the first module to simultaneously perform the perception function and the RRM measurement function, which can reduce the overhead of the perception signal and the RRM measurement signal, and can also avoid the energy consumption caused by the terminal receiving the signal multiple times and making multiple measurements. The chirp has low power and therefore low energy consumption, which can further reduce the energy consumption of the terminal.

[0117] After the first module completes the sensing and RRM measurement functions, it can report the results via an uplink channel, such as PUCCH. The reporting rule is indicated by the LP-WUS as periodic or event-triggered.

[0118] In one possible scenario, the LP-WUS indicates that the reporting of the perception results or RRM measurement results is periodic. The LP-WUS may indicate the first period or the second period, and the first period may be smaller than the second period. It is understandable that the configuration of the first period and the second period may be determined based on the latency requirements of the first module and the base station for the terminal. The switching between the first period and the second period is indicated by the LP-WUS, that is, the LP-WUS may indicate that the reporting period of the perception results or RRM measurement results is the first period or the second period. Based on this solution, different periods are configured to meet different latency requirements and be compatible with terminals of different capabilities.

[0119] In another possible scenario, the reporting of the perception result or RRM measurement result indicated by the LP-WUS is based on an event trigger. The LP-WUS may indicate an event, such as satisfying a threshold condition. When the threshold condition is satisfied, the terminal may report the perception result or RRM measurement result based on the first module. The base station may receive the perception result or RRM measurement result according to the event.

[0120] It can be understood that the threshold condition may include one or more of the number of receptions of the perception signal or the RRM measurement signal, the reference signal receiving power (RSRP) threshold of the perception signal or the RRM measurement signal, the reference signal receiving quality (RSRQ) of the perception signal or the RRM measurement signal, or the signal to interference plus noise ratio (SINR) threshold of the perception signal or the RRM measurement signal.

[0121] The following is a schematic diagram of the events described in conjunction with Table 5.

[0122] As shown in Table 5, when the LP-WUS indication event is A1, A2, A4, A5, or B1, if the perception signal or RRM measurement signal meets the threshold condition, the perception result or RRM measurement result can be reported. For example, the threshold condition may include an RSRP threshold of 0 to 127, that is, when the RSRP of the RRM measurement signal or the perception signal is between 0 and 127, the terminal can report the perception result or RRM measurement result. For another example, the threshold condition may include an RSRQ threshold of 0 to 127, that is, when the RSRQ of the RRM measurement signal or the perception signal is between 0 and 127, the terminal can report the perception result or RRM measurement result. For another example, the threshold condition may include an SINR threshold of 0 to 127, that is, when the SINR of the RRM measurement signal or the perception signal is between 0 and 127, the terminal can report the perception result or RRM measurement result.

[0123] It will be understood that the events shown in Table 5 are merely illustrative and do not constitute a limitation on the events that trigger reporting of perception results or RRM measurement results in the embodiments of the present application.

[0124] Based on the above solution, the LP-WUS may indicate a period / triggering event for reporting the perception result or the RRM measurement result, and the terminal may report the perception result or the RRM measurement result according to the period / event.

[0125] In one possible scenario, base station processing operations may be performed by the CU, and base station transceiver operations may be performed by the DU or RU. For example, the CU may determine the LP-WUS and send it to the DU. The DU may send the LP-WUS to the terminal, or the DU may send the LP-WUS to the RU, which then sends it to the terminal.

[0126] In another possible scenario, the base station's processing operations can be performed by the CU-CP, and the base station's transceiver operations can be performed by the DU or RU. For example, the CU-CP can determine the LP-WUS and send the LP-WUS to the DU. The DU can send the LP-WUS to the terminal, or the DU can send the LP-WUS to the RU, which then sends it to the terminal.

[0127] In the O-RAN scenario, the operations performed by the above CU can be performed by the O-CU, the operations performed by the DU can be performed by the O-DU, the operations performed by the RU can be performed by the O-RU, and the operations performed by the CU-CP can be performed by the O-CU-CP.
