Description

Technical Field

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

[0002] In Release 18, the 3rd Generation Partnership Project (3GPP) has been researching low-power (LP) wake-up signals (WUS) with the aim of evaluating the potential of terminals equipped with low-power radios (LR) to reduce power consumption. Generally, even when a terminal is not transmitting or receiving 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, the LR will periodically measure and detect the LP-WUS, and the main radio (MR) can be turned off when the LR is active and searching for potential LP-WUS signals. The LR can wake up the MR to transmit and receive data when a LP-WUS is detected.

[0003] However, each turn-on and turn-off of the MR incurs additional energy consumption. Among them, when the power amplifier (PA) of the MR is turned on, there is a power ramp-up, which brings a certain time delay and additional power consumption from zero to the steady state. Therefore, it is difficult to achieve an energy-saving effect by frequently waking up the MR. Summary of the Invention

[0004] This application provides a communication method and apparatus, aiming to reduce the power consumption of terminal devices.

[0005] In a first aspect, a communication method is provided. This method can be executed by a first communication device or a chip / chip system. Among them, the first communication device can be a network device or a terminal device. In this method, the first communication device includes a first module and a second module, and the power consumption of the first module is lower than that of the second module. Among them, the first communication device receives a low-power wake-up signal, and the low-power wake-up signal indicates the function to be executed by the first module. The first communication device activates the first module to execute the function.

[0006] Based on the above solution, the function of the first module is indicated by a low-power wake-up signal. Therefore, the terminal can wake up the first module to execute the corresponding function. Compared with the related art in which all functions are executed by the second module, the number of times of waking up the second module can be reduced. Therefore, the second module can be prevented from being frequently woken up, achieving the purpose of energy saving.

[0007] Second aspect, a communication method is provided. This method can be executed by a second communication device or a chip / chip system. Among them, 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, and the low-power wake-up signal indicates the functions executed by a first module included in the communication device, and the power consumption of the first module is lower than that of a second module included in the communication device. The second communication device sends the low-power wake-up signal to the communication device.

[0008] In a possible implementation 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, sensing, or updating radio frequency channel data RF-map.

[0009] Based on the above solution, the first module has a simple structure, large data processing delay, and low power consumption. Therefore, it is suitable for use in small data transmission scenarios with low data volume and insensitive delay. In addition, the functions of channel state information measurement and radio resource management measurement can detect measurement signals on a partial bandwidth or detect measurement signals received by partial antenna ports. Therefore, they can be executed by the first module to achieve the purpose of energy saving. For sensing or updating radio frequency channel data, it can be achieved by measuring linear signals, such as chirp signals. Therefore, it can be executed by the first module to reduce the energy consumption of the communication device.

[0010] In a possible implementation of the first aspect and the second aspect, the function includes sensing, and the low-power wake-up signal also indicates one or more of the following: the waveform of the sensing signal, the waveform of reporting the sensing result, the number of times of sensing the time domain resources of the sensing signal, or the time of reporting the sensing result.

[0011] Based on the above solution, when the low-power wake-up signal indicates that the function of the first module includes sensing, the low-power wake-up signal can also indicate the configuration information of sensing, so that the terminal can wake up the first module and perform sensing based on the configuration information of sensing.

[0012] In a possible implementation of the first aspect and the second aspect, the waveform of the sensing signal includes a chirp signal or an orthogonal frequency division multiplexing (OFDM) signal.

[0013] Based on this solution, due to the chirp linear modulation signal, the processing at the sending end and the receiving end is simple, the power consumption is low, and the resolution for sensing the environment and target position, speed, and texture is high. While the power of OFDM is high and the coverage is strong, so a relatively accurate sensing result can be obtained.

[0014] In a possible implementation of the first aspect and the second aspect, the function includes radio resource management measurement, and the low-power wake-up signal further indicates one or more of the following: the measured signal format or the measurement rule.

[0015] Based on this solution, when the low-power wake-up signal indicates that the function of the first module includes radio resource management measurement, the low-power wake-up signal may further indicate the configuration information of the radio resource management measurement, and the terminal can wake up the first module to perform radio resource management measurement based on the configuration information.

[0016] In a possible implementation of the first aspect and the second aspect, 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 more accurate detection results can be obtained, while the low-power synchronization signal can simplify the format of the SSB and can be transmitted and measured with less power.

[0017] In a possible implementation of the first aspect and the second aspect, the measurement rule includes relaxed measurement or normal measurement. Based on this solution, the LP-WUS can indicate the measurement rule of the SSB or the low-power synchronization signal.

[0018] In a possible implementation of the first aspect and the second aspect, 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 start position of the measurement window. Based on this solution, the low-power wake-up signal can indicate the 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 this measurement configuration, receive, and measure the SSB or the low-power synchronization signal.

[0019] In a possible implementation of the first aspect and the second aspect, the radio resource management measurement includes neighbor cell measurement, and the low-power wake-up signal further indicates the number of neighbor cells associated with the cell where the terminal device is located.

[0020] Based on this solution, for neighbor cell measurement, the low-power wake-up signal indicates the number of neighbor cells associated with the cell where the terminal is located, or rather, the low-power wake-up signal indicates the size of the list of neighbor cells associated with the cell where the terminal is located that require radio resource management measurement. The larger the number, the larger the list of radio resource management measurements and the more choices for cell handover. The smaller the number, the smaller the list of radio resource management measurements and the fewer radio resource management measurement times, and the better the energy-saving effect.

[0021] In a possible implementation of the first aspect and the second aspect, the low-power wake-up signal indication function includes sensing and radio resource management measurement, and the low-power wake-up signal also indicates that the waveform of the measurement is a chirp signal.

[0022] Based on this solution, both the sensing function and the radio resource management measurement function receive signals by the first module and measure the signals. Therefore, the low-power wake-up signal can indicate that the first module simultaneously executes the sensing function and the radio resource management measurement function, which can reduce the overhead of the sensing signal and the signal for radio resource management measurement, and can also avoid the energy consumption caused by the terminal receiving signals and measuring multiple times. Moreover, the power of the chirp is small, so the energy consumption is low, which can further reduce the energy consumption of the terminal.

[0023] In a third aspect, a communication device is provided, including: a processing unit and a transceiver unit. The transceiver unit is used to receive a low-power wake-up signal, and the low-power wake-up signal indicates the function executed by the first module. The processing unit is used to activate the first module and execute the function.

[0024] In a fourth aspect, a communication device is provided, including: a processing unit and a transceiver unit. The processing unit is used to determine a low-power wake-up signal, and the low-power wake-up signal indicates the function executed by the first module included in the communication device, and the power consumption of the first module is lower than that of the second module included in the communication device. The transceiver unit is used to send the low-power wake-up signal to the first communication device.

[0025] In a possible implementation of the third aspect and the fourth aspect, the function includes one or more of the following: channel state information measurement, radio resource management measurement, small data transmission, sensing, or updating radio frequency channel data RF-map.

[0026] In a possible implementation of the third aspect and the fourth aspect, the function includes sensing, and the low-power wake-up signal also indicates one or more of the following: the waveform of the sensing signal, the waveform of reporting the sensing result, the number of times of sensing the time-domain resource of the sensing signal, or the time of reporting the sensing result.

[0027] In a possible implementation of the third aspect and the fourth aspect, the waveform of the sensing signal includes a chirp signal or an orthogonal frequency division multiplexing (OFDM) signal.

[0028] In a possible implementation of the third aspect and the fourth aspect, the function includes radio resource management measurement, and the low-power wake-up signal also indicates one or more of the following: the signal format of the measurement or the measurement rule.

[0029] In a possible implementation of the third and fourth aspects, the measured signal format includes a low-power synchronization signal or a synchronization signal block.

[0030] In a possible implementation of the third and fourth aspects, the measurement rules include relaxed measurement or normal measurement.

[0031] In a possible implementation of the third and fourth aspects, the measurement rules include 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.

[0032] In a possible implementation of the third and fourth aspects, the radio resource management measurement includes neighbor cell measurement, and the low-power wake-up signal further indicates the number of neighbor cells associated with the cell where the terminal device is located.

[0033] In a possible implementation of the third and fourth aspects, the low-power wake-up signal indication function includes sensing and radio resource management measurement, and the low-power wake-up signal further indicates that the waveform of the measurement is a chirp signal.

[0053] To facilitate understanding of the technical solutions provided by the embodiments of the present application, the following explains and describes the technical terms involved in the embodiments of the present application.

[0054] 1) The low power wake up signal (LP-WUS) is used in multiple low power communication protocols, such as long range radio (LoRa), bluetooth, or wireless fidelity (WiFi). LP-WUS allows for the design and implementation of low power receivers, which helps reduce device power consumption. LP-WUS is very similar to WUS, which is sent based on the traditional Zadoff-Chu (ZC) sequence and the downlink control information (DCI) in format 2-6 of the physical downlink control channel (PDCCH). If WUS is detected, the paging message will continue to be decoded; otherwise, the device will return to the sleep state and wait for the next opportunity to receive WUS.

[0055] The technical solutions of the embodiments of this 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), Worldwide Interoperability for Microwave Access (WiMAX) communication systems, fifth generation communication systems (5 th generation, 5G), next generation wireless communication systems, such as 6G, etc., which are not limited here.

[0056] Figure 1 is a schematic diagram of the architecture of the communication system 1000 to which the embodiments of this application are applied. As Figure 1 shown, the communication system includes a radio access network 100. Among them, the radio access network 100 may include at least one network device (such as Figure 1 110a and / or 110b in Figure 1 ), and may also include at least one terminal device (such as Figure 1This is only a schematic diagram. Other network devices may also be included in this communication system, such as wireless relay devices and wireless backhaul devices, which are not drawn in Figure 1 here.

[0057] A network device is a network-side device with wireless transceiver functions. The network device may be a device in a radio access network (RAN) that provides wireless communication functions for terminal devices, called a RAN device. For example, the network device may be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a 5th generation (5G) mobile communication system, a next generation NodeB in a 6th generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.; it may also be a module or unit that completes some functions of the base station. For example, it may be a central unit (CU) or a distributed unit (DU). Here, the CU completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and may 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 may also complete some or all of the functions of the physical layer. For specific descriptions of the above protocol layers, reference may be made to the relevant technical specifications of the 3rd generation partnership project (3GPP). The network device may be a macro base station (such as Figure 1 110a in Figure 1 ), or a micro base station or an indoor station (such as 110b in ), or a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technologies and specific device forms adopted by the network device.

[0058] In another possible scenario, multiple RAN nodes cooperate to assist a terminal in achieving wireless access, and different RAN nodes respectively implement partial functions of a base station. For example, the RAN nodes can be a CU, a DU, a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately provided, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as included in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0059] In different systems, the CU (or CU-CP and CU-UP), the DU, or the RU can also have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (ORAN) system, the CU can also be called an O-CU (open CU), the DU can also be called an O-DU, the CU-CP can also be called an O-CU-CP, the CU-UP can also be called an O-CU-UP, and the RU can also be called an O-RU. For the convenience of description, in this application, the CU, CU-CP, CU-UP, DU, and RU are used as examples for description. Any one of the 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.

[0060] A terminal device is a user-side device with wireless transceiver capabilities. A terminal device can also be referred to as a user equipment (UE), mobile station, mobile terminal, etc. Terminal devices can be widely applied 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 home, smart office, smart wearables, smart transportation, smart city, etc. Terminal devices can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc. Embodiments of this application do not limit the specific technologies and specific device forms adopted by the terminal device.

[0061] The network device and the terminal device can be fixed in position or movable. The network device and the terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on airplanes, balloons, and artificial satellites in the air. Embodiments of this application do not limit the application scenarios of the network device and the terminal device.

[0062] The roles of the network device and the terminal device can be relative. For example, Figure 1 the helicopter or drone 120i in [description] can be configured as a mobile network device. For the terminal devices 120j that access the radio access network 100 through 120i, the terminal device 120i is a network device; but for the network device 110a, 120i is a terminal device, that is, the communication between 110a and 120i is through the radio air interface protocol. Of course, the communication between 110a and 120i can also be through the interface protocol between network devices. In this case, relative to 110a, 120i is also a network device. Therefore, both the network device and the terminal device can be uniformly referred to as communication devices. Figure 1 110a and 110b in [description] can be referred to as communication devices with network device functions. Figure 1 120a - 120j in [description] can be referred to as communication devices with terminal device functions.

[0063] In the embodiments of the present application, the functions of the network device can also be performed by a module (such as a chip) in the network device, or can be performed by a control subsystem including the functions of the network device. The control subsystem including the functions of the network device here can be a control center in the above application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of the terminal device can also be performed by a module (such as a chip or a modem) in the terminal device, or can be performed by a device including the functions of the terminal device. In the following, an example will be described in which the functions of the terminal device are performed by the terminal, and the functions of the network device are performed by the base station.

[0064] With the development of 5G technology, the 5G network has higher and higher requirements for the capabilities of terminals. As the requirements for terminal capabilities increase, the hardware of the terminal will increase accordingly, and the power consumption of the terminal will inevitably increase. Compared with LTE terminals, the maximum power supported by 5G terminals is 29 dBm. In typical services, such as comprehensive web browsing, instant messaging, games, or food, etc., the communication power consumption of 5G terminals increases by more than 200% on average compared with LTE terminals. The long-term battery life of the terminal is an important aspect of the user experience and will affect the applicability of 5G terminals or services. Therefore, the long-term battery life of 5G terminals faces great challenges, and studying how to save the power consumption of 5G terminals is the key to solving this problem.

[0065] Referring to Figure 2 , the terminal can include a low power wake up radio (LR) and a main radio (MR). It can be understood that LR and MR can be integrated as logical function modules on the same processor (such as a chip), or LR and MR can be separate processors (such as chips) respectively. The power consumption of LR is lower than that of MR. In another example, the bandwidth of LR is also lower than that of MR. It should be noted that MR and LR are only shown as exemplary names, LR can also be called a secondary module, and MR can also be called a primary module. The present application does not make specific limitations. In the embodiments of the present application, an example will be described in which LR is the first module and MR is the second module.

[0066] In Release 18, the 3rd generation partnership project (3GPP) has been studying the low power (LP) wake up signal (WUS) with the aim of evaluating the potential of 5G terminals with low LR to reduce power consumption. Generally speaking, even when a 5G terminal does not send or receive any data, it will consume dozens of milliwatts of power, which is called idle power consumption. This idle power consumption is caused by the fact that 5G terminals must regularly measure and detect potential LP-WUS. Among them, the LR will regularly measure and detect the LP-WUS, and the MR can be turned off when the LR is active and searching for potential LP-WUS signals. The LR can wake up the MR to send and receive data when a LP-WUS is detected.

[0067] However, each turn-on and turn-off of the MR has additional energy consumption. Among them, when the power amplifier (PA) of the MR is turned on, there is a power ramp-up, which brings a certain time delay and additional power consumption from zero to a stable state. For example, when doing radio resource management (RRM) measurements, the LR can receive the LP-WUS and wake up the MR for RRM measurements. After the measurements are completed, the MR can go to sleep. Another example is that after the LR receives the LP-WUS, it can wake up the MR to receive and demodulate signals. In these processes, waking up the MR will generate additional power consumption. Therefore, it is difficult to achieve an energy-saving effect by frequently waking up the main module.

[0068] In view of this, the embodiments of the present application provide a communication method. In this method, the functions performed by the LR are indicated by the LP-WUS. Therefore, the terminal can wake up the LR and perform the corresponding functions. Compared with the related art where all functions are performed by the MR, the number of times of waking up the MR can be reduced. Therefore, frequent waking up of the MR can be avoided, achieving the purpose of energy saving.

[0069] Refer to Figure 3 , which is an exemplary flowchart of a communication method provided by the embodiments of the present application and may include the following operations. Figure 3 In the illustrated embodiment, the first communication device may include a first module and a second module, and the power consumption of the first module is lower than that of the second module. Figure 3 In the illustrated embodiment, the first communication device is taken as a terminal and the second communication device is taken as a base station for illustration.

[0070] S301: The base station sends a low power wake up signal to the terminal.

[0071] Correspondingly, the terminal receives the low power wake up signal from the base station.

[0072] Among them, 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 the embodiments 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. In the following description, it is assumed that the low-power wake-up signal is LP-WUS for illustration purposes.

[0073] S302: The terminal activates the first module to execute the function.

[0074] Among them, the terminal can receive LP-WUS. For example, the terminal can receive LP-WUS through the first module, and obtain the information carried by LP-WUS after demodulation. For example, the terminal obtains the first indication information carried by LP-WUS after demodulation, and activates the first module to execute the function indicated by the first indication information based on the first indication information.

[0075] It can be understood that activating the first module can be understood as turning on the first module or waking up the first module. Substantially, it is to execute the function indicated by LP-WUS through the first module.

[0076] Next, the function of the first module indicated by the first indication information carried by LP-WUS will be introduced in combination with Table 1.

[0077] Table 1: An example of the function of the first module indicated by the first indication information

[0078]

[0079]

[0080] In Table 1, when the value of the first indication information is 0, it can indicate to activate (or turn on) the measurement function of the channel state information of the first module. Activating the measurement function of the channel state information 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 transmission function of the physical uplink control channel (PUCCH) of the first module. The first module can send a channel quality indication (CQI) based on the measurement result of CSI-RS 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 transmission function of the PUCCH. Compared with the second module executing the channel state information measurement function, it can save the power consumption of the terminal.

[0081] When the value of the first indication information is 1, it can indicate to activate (or turn on) the RRM measurement function of the first module. 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 of neighboring cells and activating the function of the first module to send PUCCH. Although the structure of the first module is simple, the first module can complete the signal measurement of neighboring cells and the function of sending PUCCH. Compared with the RRM measurement function executed by the second module, it can save the power consumption of the terminal.

[0082] When the value of the first indication information is 2, it can indicate to activate (or turn on) the small data transmission function of the first module. The first module has a simple structure, large data processing delay and low power consumption. Therefore, it is suitable for use in small data transmission (SDT) scenarios with low data volume and insensitive delay. Therefore, the first indication information can be set to 2 to indicate the terminal to activate the first module to send or receive data.

[0083] In Table 1, activating the sensing function of the first module can be understood as activating (or turning on) the function of the first module to receive sensing signals and send sensing results. 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 sensing signals and process to obtain the RF-map. In the embodiments of the present application, the RF-map can indicate the following two aspects of information:

[0084] On the one hand, the RF-map corresponds to a certain geographical area and is used to indicate the geographical locations and area sizes of multiple regions divided within the geographical area. On the other hand, the RF-map can indicate the channel quality prediction values of each region among the multiple regions. Wherein, the geographical area can be a region within a certain range in the real physical world. Wherein, the multiple regions can be regions obtained by dividing the geographical area in a certain manner. In the present application, the shapes, contours, sizes, radii, and areas of different regions are the same. The geographical locations of different regions are different. There is no overlap between different regions.

[0085] In a possible case, LP-WUS can indicate one of the functions in Table 1 above. The terminal can activate the first module to execute the function indicated by LP-WUS. In another possible case, LP-WUS can indicate multiple functions in Table 1 above. The terminal can activate the first module and execute multiple functions one by one according to the indication of LP-WUS.

[0086] It should be understood that the correspondence between the first indication information shown in Table 1 and the functions of the first module is only shown as an example and does not constitute a limitation on this correspondence. In addition, the values of the first indication information in Table 1 are also shown as examples. In the embodiments of the present application, the first indication information can also indicate the functions of the first module by means of indication function identifiers, etc. The indication information in the following text, such as the second indication information, the third indication information, etc., is also shown as examples and will not be described repeatedly.

[0087] Hereinafter, taking LP-WUS indicating that the first module performs sensing functions and RRM measurement functions as an example for illustration. LP-WUS can also indicate the configuration information of sensing or the configuration information of RRM measurement.

[0088] In a possible implementation manner, LP-WUS indicates that the first module performs sensing functions. Sensing, as one of the important concepts of 5G and 6G, is usually deployed along with the cellular network and has two modes: self-transmitting and self-receiving, and self-transmitting and other-receiving. The base station can indicate to the first module to perform sensing through LP-WUS.

[0089] When LP-WUS indicates that the first module performs sensing functions, LP-WUS can indicate one or more of the waveform of the sensing signal, the waveform of reporting the sensing result, the time-domain resources of the sensing signal, the number of sensing times, or the moment of reporting the sensing result, which will be introduced below.

[0090] In an example, LP-WUS can indicate the time-domain resources of the sensing signal. Refer to Figure 4A , LP-WUS carries the time-domain resource indication K3, and K3 refers to the time interval from receiving LP-WUS to performing sensing. LP-WUS can also indicate the sensing interval T1, and the sensing interval T1 refers to the interval between two sensing signals. LP-WUS can also indicate the number of sensing times n, and the number of sensing times n is an integer greater than or equal to 1. The base station indicates the number of sensing times n through LP-WUS, and the terminal can determine the number of sensing signals. By indicating K3 and the sensing interval T1 through LP-WUS, the terminal can determine the time-domain resources of each sensing signal, so as to activate the first module and accurately receive the sensing signals.

[0091] After the first module receives n sensing signals, the sensing result can be fed back through an uplink channel, such as PUCCH. In another example, LP-WUS can indicate the time-domain resources of the sensing result, and the terminal can send PUCCH through the first module and the time-domain resources of the sensing result, and the PUCCH carries the sensing result. Refer to Figure 4B , LP-WUS can indicate the time-domain resource K4 of the sensing result, and K4 indicates the time interval from receiving LP-WUS to sending the sensing result.

[0092] It can be understood that the table of K4 can be a newly defined time-domain resource, which can be referred to the table of K2 for uplink scheduling in the related art. Alternatively, the table of K4 can reuse the table of K2 for uplink scheduling in the related art, with the difference that the table of K4 is smaller than the table of K2.

[0093] In another example, LP-WUS can indicate the waveform of the sensing signal. For example, LP-WUS can carry second indication information, and the second indication information can indicate the waveform of the sensing signal. Hereinafter, it will be introduced in conjunction with Table 2.

[0094] Table 2: An example of the second indication information indicating the waveform of the sensing signal

[0095] Second indication information Waveform of the sensing signal 0 Chirp signal chirp 1 OFDM

[0096] In Table 2, when the value of the second indication information is 0, it can indicate that the waveform of the sensing signal is chirp, and the information is carried by the frequency point and slope of the chirp signal. Since the chirp linear modulation signal, the processing at the sending end and the receiving end is simple, the power consumption is low, and the resolution for the sensing environment and target position, speed, and texture is high.

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

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

[0099] In another example, LP-WUS can report the waveform of the sensing result. For example, LP-WUS can carry third indication information, and the third indication information can indicate the waveform of the reported sensing result. Hereinafter, it will be introduced in conjunction with Table 3.

[0100] Table 3: An example of the third indication information indicating the waveform of the sensing signal

[0101] Third indication information Waveform for reporting the sensing result 0 Chirp signal chirp 1 OFDM

[0102] In Table 3, when the value of the third indication information is 0, it can indicate that the waveform for reporting the sensing result is chirp. When the value of the third indication information is 1, it can indicate that the waveform for reporting the sensing result is OFDM. Among them, the transmission power of chirp is small and the energy consumption is low. Therefore, by using chirp to carry the sensing result, the power consumption of the terminal can be saved. While the power of OFDM is high and the coverage is strong, so the possibility of the sensing result being received can be improved.

[0103] It should be noted that the way the third indication information shown in Table 3 indicates the waveform for reporting the sensing result is only shown as an example. It can also be that when the value of the third indication information is 1, it indicates that the waveform for reporting the sensing result is chirp, and when the value of the third indication information is 0, it indicates that the waveform for reporting the sensing result is OFDM. The third indication information can be a newly added indication information, or it can also reuse the existing fields in LP-WUS. This application does not make specific limitations.

[0104] It can be understood that the second indication information and the third indication information can be designed as one indication information, such as the fourth indication information, to jointly indicate the waveform of the sensing result and the waveform for reporting the sensing result. Below, it will be introduced in combination with Table 4.

[0105] Table 4: An example of a fourth indication information

[0106] Fourth indication information Waveform of the sensing signal Waveform for reporting the sensing result 0 chirp OFDM 1 chirp chirp 2 OFDM chirp 3 OFDM OFDM

[0107] As shown in Table 4, the fourth indication information can be used to jointly indicate the waveform of the sensing signal and the waveform for reporting the sensing result. Assuming that the fourth indication information is 2 bits, when the value of the fourth indication information is 0, it can indicate that the waveform of the sensing signal is chirp and the waveform for reporting the sensing result is OFDM. When the value of the fourth indication information is 1, it can indicate that the waveform of the sensing signal is chirp and the waveform for reporting the sensing result is chirp, and so on.

[0108] It should be noted that the way the fourth indication information shown in Table 4 indicates the waveform of the sensing result and the waveform for reporting the sensing result is only shown as an example. The fourth indication information can be a newly added indication information, or it can also reuse the existing fields in LP-WUS. This application does not make specific limitations.

[0109] Based on the above solution, the base station indicates the configuration information for sensing through LP-WUS, and indicates the first module to perform the sensing function. After receiving LP-WUS, the terminal can obtain the configuration information for sensing and activate the first module to perform the sensing function based on this configuration information.

[0110] In another possible implementation, LP-WUS instructs the first module to perform the RRM measurement function. For example, LP-WUS can instruct the first module to perform functions such as cell measurement and / or neighbor cell measurement.

[0111] When LP-WUS instructs the first module to perform the RRM measurement function, LP-WUS can indicate the type of measurement signal. For example, LP-WUS can indicate to use the LP-synchronization signal (SS) to complete the measurement, or indicate to use the SSB to complete the measurement. Exemplarily, LP-WUS can include fifth indication information, and the fifth indication information can indicate to use the LP-SS to complete the measurement or indicate to use the 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 can indicate to use the LP-SS to complete the measurement, and when the value of the fifth indication information is 1, it can indicate to use the SSB to complete the measurement. Vice versa, when the value of the fifth indication information is 1, it can indicate to use the LP-SS to complete the measurement, and when the value of the fifth indication information is 0, it can indicate to use the SSB to complete the measurement.

[0112] Different from the related art where reference signals such as the SSB are configured through radio resource control (RRC) to complete the RRM measurement, in the above solution of the present application, LP-WUS can be used to indicate to use the LP-SS to complete the RRM measurement, which can simplify the format of the SSB and transmit and measure with less power.

[0113] In one example, LP-WUS can indicate the measurement rules for the RRM measurement. For example, LP-WUS can carry sixth indication information, and the sixth indication information can indicate that the measurement rules for the RRM measurement use normal measurement rules or use relaxed measurement rules. Refer to Figure 5A , the relaxed measurement rules allow the SSB or LP-SS to be completed within a larger timing configuration window, achieving the purpose of energy saving by reducing the number of measurements.

[0114] In the embodiments of the present application, LP-WUS can indicate the position of the timing configuration window for the RRM measurement, such as indicating the length and start position of the timing configuration window. Refer to Figure 5B, the terminal can activate the first module and complete the measurement of SSB or LP-SS based on the start 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 the SSB within the timing configuration window (SMTC) and continue to detect in the next same timing configuration window. If LP-SS is used to complete the measurement, the first module will detect the power and beam of the LP-SS within the timing configuration window and continue the detection in the next same timing configuration window.

[0115] In another example, LP-WUS can indicate the number of measurements and the measurement period. The terminal can 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 period indicated by the number of measurements, and perform measurements on LP-SS or SSB.

[0116] In the related art, there is no end condition for the measurement of SSB. In the embodiments of the present application, LP-WUS can indicate the end condition of the RRM measurement, such as the threshold value of the measurement result. The terminal can stop the measurement when the measurement result reaches this threshold value. Another example is that LP-WUS can indicate the end moment 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 a timer. After reaching the timing duration, it can indicate the arrival of the end moment of the RRM measurement, and the terminal can stop the measurement.

[0117] In the embodiments of the present application, for neighbor cell measurement, LP-WUS indicates the number of neighbor cells associated with the cell where the terminal is located, or LP-WUS indicates the size of the list of neighbor cells associated with the cell where the terminal is located that require RRM measurement. The larger the number, the larger the list of RRM measurements and the more choices for cell handover. The smaller the number, the smaller the list of RRM measurements, the fewer RRM measurement times, and the better the energy-saving effect.

[0118] In a possible implementation manner, LP-WUS can indicate that the first module simultaneously executes the sensing function and the RRM measurement function, and LP-WUS can indicate that the sensing signal (measurement signal) is chirp. In this method, both the sensing function and the RRM measurement function are to receive signals by the first module and measure the signals. Therefore, LP-WUS can indicate that the first module simultaneously executes the sensing function and the RRM measurement function, which can reduce the overhead of the sensing signal and the signal of the RRM measurement, and can also avoid the energy consumption caused by the terminal receiving signals and measuring multiple times. Since the power of chirp is small, the energy consumption is low, which can further reduce the energy consumption of the terminal.

[0119] After the first module completes the sensing function and the RRM measurement function, the results can be reported through the uplink channel, such as the PUCCH. The reporting rule is indicated by the LP-WUS as periodic or event-triggered.

[0120] In a possible scenario, the LP-WUS indicates that the reporting of the sensing result or the RRM measurement result is a periodic report. The LP-WUS can indicate the first period or the second period, and the first period can be less than the second period. It can be understood that the configurations of the first period and the second period can be determined according to 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 can indicate that the reporting period of the sensing result or the RRM measurement result is the first period or the second period. Based on this solution, different periods can be configured to meet different latency requirements and be compatible with terminals of different capabilities.

[0121] In another possible scenario, the LP-WUS indicates that the reporting of the sensing result or the RRM measurement result is event-triggered. The LP-WUS can indicate an event, such as meeting a threshold condition. When the terminal meets the threshold condition, it can report the sensing result or the RRM measurement result based on the first module. The base station can receive the sensing result or the RRM measurement result according to the event.

[0122] It can be understood that the threshold condition can include one or more of the number of receptions of the sensing signal or the RRM measurement signal, the reference signal receiving power (RSRP) threshold of the sensing signal or the RRM measurement signal, the reference signal receiving quality (RSRQ) of the sensing signal or the RRM measurement signal, or the signal to interference plus noise ratio (SINR) threshold of the sensing signal or the RRM measurement signal.

[0123] Next, the schematic diagram of the event is introduced in combination with Table 5.

[0124]

[0125] As shown in Table 5, when the LP-WUS indication event is A1, A2, A4, A5 or B1, and the sensing signal or RRM measurement signal meets the threshold condition, the sensing 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 sensing signal is between 0 and 127, the terminal can report the sensing result or RRM measurement result. Another example is that the threshold condition may include an RSRQ threshold of 0 to 127, that is, when the RSRQ of the RRM measurement signal or sensing signal is between 0 and 127, the terminal can report the sensing result or RRM measurement result. Another example is that the threshold condition may include an SINR threshold of 0 to 127, that is, when the SINR of the RRM measurement signal or sensing signal is between 0 and 127, the terminal can report the sensing result or RRM measurement result.

[0126] It can be understood that the events shown in Table 5 are only shown as examples and do not constitute a limitation on the events that trigger the reporting of the sensing result or RRM measurement result in the embodiments of the present application.

[0127] Based on the above solution, LP-WUS can indicate the period / trigger event for reporting the sensing result or RRM measurement result, and the terminal can report the sensing result or RRM measurement result according to the period / event.

[0128] In a possible scenario, the processing operation of the base station can be performed by the CU, and the transceiver operation of the base station can be performed by the DU or RU. For example, the CU 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, and the RU sends it to the terminal.

[0129] In another possible scenario, the processing operation of the base station can be performed by the CU-CP, and the transceiver operation of the base station 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, and the RU sends it to the terminal.

[0130] 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.
