[0001] This application claims priority to the Chinese patent application No. 202410890975.X, filed on July 3, 2024, and entitled "Communication method and apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, in particular to a communication method and apparatus. BACKGROUND

[0003] In the scenario of transmitting service data between a base station and a terminal, the base station needs to configure the service to be transmitted in order to meet the service requirements. For example, for downlink service, the base station as a sender that sends service data to the terminal can explicitly determine the service requirements of the downlink service, specifically, can obtain the data volume of each bearer service of the downlink, and determine the scheduling priority of the bearer and select the bearer to be scheduled according to the input quality of service (QoS) parameter, channel quality, historical rate and other factors, in order to meet the downlink service requirements. As for uplink service, the base station as a receiver that receives service data from the terminal, how to determine the service requirements of the uplink service needs to be studied. SUMMARY

[0004] Embodiments of the present application provide a communication method and apparatus, which can enable the network side device to determine the service requirements of the uplink service, so that the network side device can take corresponding operations or open corresponding functions to meet the service requirements of the uplink service, and can better save energy.

[0005] In a first aspect, the present application provides a communication method, which can be applied to a terminal side device.

The terminal side device sends the uplink wake-up signal to a network side device.

[0006] As can be seen, in the method, the terminal side device notifies the network side device of the service requirements of the uplink service through the uplink wake-up signal, so that the network side device can determine the service requirements of the uplink service, and this way can also facilitate the network side device to wake up the module with corresponding functions based on the service requirements of the uplink service, which can better save energy compared to opening all function modules when the network side device receives a wake-up signal.

[0058] The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0059] The technical solutions of the embodiments of the present application can be applied to various communication systems. For example, the global system for mobile communications, the long term evolution (LTE) system, the universal mobile telecommunications system, the 4th generation (4G) mobile communication system, the 5th generation (5G) mobile communication system, and as the communication technology continues to evolve, the technical solutions of the embodiments of the present application can also be applied to subsequent evolved wireless communication systems, such as the 5.5th generation (5.5G) mobile communication system, the 6th generation (6G) mobile communication system, the 7th generation (7G) mobile communication system, etc. In addition, the technical solutions of the embodiments of the present application can also be applied to scenarios such as ground cellular communication, non-terrestrial network (NTN) communication, satellite communication, high altitude platform station (HAPS) communication, vehicle-to-everything (V2X) communication, integrated access and backhaul (IAB), reconfigurable intelligent surface (RIS) communication, etc.

[0060] Embodiments of the present application can be applied to the scenario of communication between a terminal device and a network device. For example, the embodiments of the present application can be applied to a standalone (SA) scenario, and can also be applied to a non-standalone (NSA) scenario. FIG. 1 is a schematic diagram of an SA scenario provided by an embodiment of the present application, and FIG. 2 is a schematic diagram of an NSA scenario provided by an embodiment of the present application.

[0061] In combination with FIG. 1, in the SA scenario, a terminal device is connected with a single base station, and the base station connected by the terminal device and the core network connected by the base station are of the same standard. For example, the core network is a 5G core network (Core), the corresponding base station is a 5G base station, and the 5G base station is directly connected to the 5G Core. For another example, the core network is a 6G Core, the corresponding base station is a 6G base station, and the 6G base station is directly connected to the 6G Core. FIG. 1 takes the core network as a 6G Core and a terminal device as a mobile phone as an example for illustration.

[0062] In combination with FIG. 2, in the NSA scenario, a terminal device is connected with base stations of the same standard at the same time, or the terminal device is connected with base stations of different standards at the same time. The NSA scenario can be applied to a terminal device in a connected state, and the NSA scenario can also be referred to as a dual connectivity (DC) scenario. For example, the core network is a 5G Core, and the terminal device is connected with a 5G base station and a 6G base station at the same time, where the 5G base station serves as a primary station and the 6G base station serves as a secondary station. For another example, the core network is a 6G Core, and the terminal device is connected with a 6G base station and a 5G base station at the same time, where the 6G base station serves as a primary station and the 5G base station serves as a secondary station. For another example, the core network is a 6G Core, and the terminal device is connected with two 6G base stations at the same time, i.e., the primary station and the secondary station are both 6G base stations. FIG. 2 takes the core network as a 5G Core, the terminal device is connected with a 5G base station and a 6G base station at the same time, and a terminal device is a mobile phone as an example for illustration.

[0063] In addition, the terminal device in the embodiments of the present application can also be referred to as a user equipment (UE), a terminal, an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile station (MS), a remote station, a remote terminal, a mobile device, a user terminal, a user agent or a user apparatus, and can be applied to 4G, 5G or even 6G systems. The terminal device in the embodiments of the present application can be a handheld device, a vehicle-mounted device, a wearable device, a computing device or other processing device connected to a wireless modem with wireless communication function. The terminal device can be a terminal with a function of connecting to a cellular base station. For example, the terminal device can be a cellular phone, a smart phone, a Pad, a wireless data card, a personal digital assistant (PDA) computer, a tablet computer, a wireless modem, a handset, a laptop computer, a machine type communication (MTC) terminal, etc. The terminal device can also be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical treatment, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, a vehicle-mounted terminal, a wireless communication device in smart factory, etc.

[0064] For example, the terminal device can be a 5G terminal. With the development of technology, the capability requirements of 5G networks for terminals are getting higher and higher: network capability improvement has higher requirements for the rate of 5G terminals; diversified applications require various forms of 5G terminals, such as smart phones, customer premises equipment (CPE), routers, laptops, televisions (TV), tablets, VR / AR, unmanned aerial vehicles, autonomous driving, wearable devices, and other applications involving terminal forms; 5G terminals should be able to support NSA and SA at the same time; 5G terminals need to support more frequency bands and larger bandwidths. With the improvement of the capability requirements of 5G terminals, the hardware of the terminal will increase, and the power consumption of the terminal will increase. As shown in FIG. 3, a 4G terminal or a 4.5G terminal supports a maximum of 1 transmit (Transmit) antenna and 2 receive (Receive) antennas, with a maximum power of 23 decibels milliwatts (dBm) and a maximum bandwidth of 20 megahertz (MHz); a 5G terminal supports a maximum of 2 transmit antennas and 2 receive antennas, with a maximum power of 29 dBm and a maximum bandwidth of 100 MHz. It can be seen that the capability of the 5G terminal is significantly greater than that of the 4G terminal or the 4.5G terminal. In typical services (such as comprehensive web browsing, instant messaging, games, videos, etc.), the power consumption of 5G terminal communication is more than 200% higher than that of 4G on average. In order to improve the endurance capability of the 5G terminal, on the terminal side, the use of larger capacity batteries, low power consumption high performance components, and power saving technology terminal screens can be used to prolong the endurance time of the terminal. On the wireless side, under the premise of ensuring effective data transmission of the terminal, unnecessary power consumption of the terminal is reduced to achieve the purpose of terminal power saving and energy saving, such as discontinuous reception (DRX), cross-slot scheduling, and reducing the number of multiple-input multiple-output (MIMO) layers, which effectively reduces the power consumption of the terminal.

[0065] In the embodiments of the present application, the network device has a wireless transceiving function, and the network device includes but is not limited to: a base station (BS), a radio network controller (RNC), a base station controller (BSC), a network device transceiver station (BTS), a home network device (for example, a home evolved Node B, or a home Node B, HNB), a baseband unit (BBU), a relay device, a transceiving node, a wireless backhaul node, a transmission and reception point (TRP; or, a transmission point, TP), a wireless fidelity (WiFi) access point (AP) (that is, a WiFi AP), a BS of world interoperability for microwave access (WiMAX) (that is, a WiMAX BS). The base station is a device deployed in a wireless access network and can provide wireless communication functions, and the base station can also be referred to as a base station device, for example, an evolved Node B (eNB or e-NodeB) in an LTE system, a Node B (Node B), a base station (gNodeB or gNB) in a 5G system, a base station in a 6G system, a base station of a future communication system, and the like. The base station can include a BBU and a remote radio unit (RRU). The BBU and the RRU can be placed in different places, for example: the RRU is pulled away, placed in a high traffic area, and the BBU is placed in a central machine room. The BBU and the RRU can also be placed in the same machine room. The BBU and the RRU can also be different components under one rack. The base station can be in the following forms: a macro base station, a micro base station (also known as a small station), a pico base station, a relay station, an access point, a balloon station, and the like.

[0066] Optionally, in some deployments of the access network device, the access network device can include a central unit (CU) and a distributed unit (DU), etc. The functions of part of the protocol layers of the access network device are placed in the CU for centralized control, and the functions of the remaining part or all of the protocol layers are distributed in the DU and controlled by the CU. In some other deployments of the access network device, the CU can also be divided into a CU-control plane (CP) and a CU-user plane (UP), etc. In some other deployments of the access network device, the network device can also be an open radio access network (ORAN / O-RAN) architecture. When the access network device is an ORAN architecture, the access network device can be a functional entity or a module in the ORAN, for example, the access network device can be a combination of one or more of the CU, the DU or the RU. In the ORAN system, the CU can also be referred to as an open (O)-CU, the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, etc. The deployment modes of the access network device listed here are only examples, and as the standard technology evolves, there can be other deployment forms of the access network device, which are not limited by the embodiments of the application.

[0067] It can be understood that the embodiments of the application take the 5G mobile communication technology system as an example for illustration, when the scheme of the embodiments of the application is applied to a 6G mobile communication technology system or other communication system, the corresponding network element name, network element deployment mode and interface can change, and the application is not limited thereto.

[0068] The related concepts involved in the embodiments of the application are described below.

[0069] 1. Low-power wake up signal (LP-WUS)

[0070] The LP-WUS is a wake-up signal transmitted by a device through a low-power radio (LR) module. The device includes a main radio (MR) module and an LR module, and the LR module is independent of the MR module. The MR module can be turned off (or in a sleep state) when the LR module is in an active state and searching for a potential wake-up signal, and be awakened after the LR module searches for a wake-up signal, which can reduce the power consumption of the device. In addition, the LR module can also be referred to as a low-power wake-up radio (LP-WUR) module.

[0071] For example, in combination with FIG. 4, the network device includes an MR module and an LR module, and the terminal device includes an MR module and an LR module. The MR module and the LR module in the network device can transmit information, and the MR module and the LR module in the terminal device can transmit information. In addition, the MR module in the network device and the MR module in the terminal device can transmit signals, and the LR module in the network device and the LR module in the terminal device can transmit signals.

[0072] The network device can send the LP-WUS and the low-power synchronization signal (LP-SS) through the LR module, and the terminal device receives the LP-WUS and the LP-SS through the LR module to complete the wake-up and synchronization of the MR module. Further, the terminal device can complete the measurement of the channel quality through the synchronization signal and the PBCH block (SSB) signal or the channel state information reference signal (CSI-RS), where the PBCH represents the physical broadcast channel (PBCH). The terminal device can also complete the reception and transmission of data through the MR module. Similarly, the terminal device can also send the LP-WUS through the LR module, and the network device can wake up the MR module after detecting the LP-WUS through the LR module, which will not be repeated here.

[0073] It can be seen that the device transmits the LP-WUS through the LR module, which can reduce the power consumption of the device compared with the method of transmitting the wake-up signal (WUS) through the MR module. The wake-up signal transmitted through the MR module is based on the traditional Zadoff-Chu sequence and the downlink control information (DCI) of Format 2-6 (i.e., Format 2-6) in the physical downlink control channel (PDCCH).

[0074] The uplink wake up signal (UL WUS) mentioned in the embodiments of the present application is the LP-WUS sent by the terminal side device through the LR module, and for the network side device, the network side device detects the UL WUS through the LR module. In an optional manner, the UL WUS can use the time-frequency domain resource of the physical random access channel (PRACH) for transmission. In addition, the downlink wake up signal (DL WUS) mentioned in the embodiments of the present application is the LP-WUS sent by the network side device through the LR module, and for the terminal side device, the terminal side device detects the DL WUS through the LR module.

[0075] In uplink and downlink transmission data, data is transmitted through a quality of service (QoS) flow of a protocol data unit (PDU) session. Among them, the terminal device and the base station transmit the QoS flow through a radio bearer (RB), and the base station and the user plane function network element in the core network transmit the QoS flow through a tunnel. As shown in FIG. 5, FIG. 5 takes 5G as an example for illustration.

[0076] In the scenario of transmitting service data between the base station and the terminal device, the base station needs to configure the to-be-transmitted service to meet the service demand. For example, for downlink service, the base station as a sender that sends service data to the terminal device can explicitly obtain the service demand of the downlink service, specifically can obtain the data volume of each downlink bearer service, and comprehensively determine the scheduling priority of the bearer and select the bearer to be scheduled according to the input quality of service (QoS) parameter, channel quality, historical rate and other factors, to meet the downlink service demand.

[0077] For uplink service, the base station as a receiver that receives service data from the terminal also needs to obtain the service demand of the uplink service. For example, the terminal device notifies the base station of the service priority through a logical channel group, but the classification granularity of the logical channel group is too coarse to accurately reflect the priority of the terminal service. For another example, the terminal device notifies the base station of the size of the data to be sent by the terminal through a buffer status report (BSR), but the size of the data notified through the BSR is a range, and the base station still cannot accurately know the size of the data sent by each service.

[0078] The embodiment of the present application provides a communication method, in which a terminal-side device notifies a network-side device of service requirements of uplink service by sending an uplink wake-up signal, the service requirements of uplink service can include one or more of the following: a service type of uplink service, a data volume of uplink service, or a priority of uplink service, so that the network-side device obtains more accurate service requirements of uplink service. In addition, after receiving the uplink wake-up signal, the network-side device can also wake up corresponding functional modules based on the service requirements of uplink service, without waking up all functional modules, and better achieving network energy saving.

[0079] The embodiment of the present application is described in detail below with reference to the accompanying drawings. The embodiment of the present application takes a terminal-side device and a network-side device as an execution subject to illustrate the corresponding method. For example, the terminal-side device can be a terminal device, or can be a chip supporting the terminal device to implement the corresponding method, or can be a logic module or software capable of implementing all or part of the functions of the terminal device. The network-side device can be a network device, or can be a chip supporting the network device to implement the corresponding method, or can be a logic module or software capable of implementing all or part of the functions of the network device.

[0080] Please refer to FIG. 6, which is a flowchart of a communication method provided by the embodiment of the present application, and the communication method includes the following steps.

[0081] S101, a terminal-side device generates an uplink wake-up signal, the uplink wake-up signal is related to service requirements of uplink service, and the service requirements of uplink service include one or more of the following: a service type of uplink service, a data volume of uplink service, or a priority of uplink service.

[0082] In an optional implementation, the service type of uplink service includes one or more of the following: a positioning request, sensing, or communication. In addition to the service types mentioned herein, other service types are also possible, which are not limited.

[0083] Optionally, when the service type of uplink service includes sensing, the service type of uplink service specifically includes one of the following: self-initiated and self-received sensing, or sensing requiring double-end transmission. It can be seen that the service type of uplink service can be a self-initiated and self-received sensing type, or can be a sensing type requiring double-end transmission. In addition to the sensing types mentioned herein, other sensing types are also possible, which are not limited.

[0084] Optionally, when the service type of the uplink service includes communication, the service type of the uplink service specifically includes one or more of the following: uplink data transmission, uplink measurement quantity feedback, random access, or uplink scheduling request. It can be seen that the uplink service can be used for transmitting uplink data, or can also be used for feeding back uplink measurement quantity, or can also be used for performing a random access process, or can also be used for requesting uplink scheduling. In addition, it can be other types of communication services in addition to the communication services mentioned herein, without limitation. Optionally, the feedback of the uplink measurement quantity includes one or more of the following: part or all of channel state information (CSI) feedback, reference signal receiving power (RSRP) reporting, tracking area (TA) measurement, etc.

[0085] In an optional embodiment, the data amount of the uplink service is a specific value of the uplink service data amount, or a range of the uplink service data amount. For example, the uplink service data is a large file, or a small file, or a continuous data like a live type.

[0086] In an optional embodiment, the priority of the uplink service can be represented by a QoS value; for example, the larger the QoS value, the higher the priority, or vice versa, the smaller the QoS value, the higher the priority.

[0087] In addition, in an optional manner, the service requirement of the uplink service can include other aspects of service requirements in addition to the service type, data amount, or priority mentioned above, or can be replaced by other aspects of service requirements, without limitation.

[0088] In an optional embodiment, the uplink wake-up signal is related to the type of the terminal-side device. The embodiments of the present application do not limit the type of the terminal-side device, for example, the terminal-side device can be a reduced capability (RedCap) terminal, or can also be a normal terminal (normal UE), etc. In addition, it should be noted that the uplink wake-up signal is related to both the service requirement of the uplink service and the type of the terminal-side device, or the uplink wake-up signal is related to the type of the terminal-side device but not related to the service requirement of the uplink service, both of which are within the protection scope of the embodiments of the present application.

[0089] S102, the terminal-side device sends an uplink wake-up signal to the network-side device.

[0090] In an optional implementation, the terminal-side device repeatedly sends the uplink wake-up signal to the network-side device in the first time window, and different repetition numbers of the uplink wake-up signal correspond to different service requirements of the uplink service. The first time window may be predefined or configured, without limitation. Understandably, the terminal-side device may determine the repetition number of the uplink wake-up signal based on the service requirement of the uplink service, and repeatedly send the uplink wake-up signal according to the determined repetition number, so that the network-side device may determine the service requirement of the uplink service based on the repetition number of the uplink wake-up signal detected (for example, based on the repetition number of the uplink wake-up signal detected in the third time window). As can be seen, the terminal-side device may notify the network-side device of the service requirement of the uplink service by repeatedly sending the uplink wake-up signal.

[0091] In addition, in the embodiments of the present application, the time window may also be replaced by time, time unit, time period, or occasion. For example, the first time window may also be replaced by the first time, the first time unit, the first time period, or the first occasion. The second time window, the third time window, and the like mentioned hereinafter are similar, and will not be described hereinafter.

[0092] For example, taking the service requirement of the uplink service as an example, the correspondence between the repetition number of the uplink wake-up signal and the priority of the uplink service is shown in Table 1.

[0093] Table 1

[0094] Based on Table 1, if the uplink service of the terminal-side device is non-urgent service, the terminal-side device repeatedly sends the uplink wake-up signal to the network-side device twice in the first time window. If the uplink service of the terminal-side device is medium-urgent service, the terminal-side device repeatedly sends the uplink wake-up signal to the network-side device four times in the first time window. If the uplink service of the terminal-side device is urgent service, the terminal-side device repeatedly sends the uplink wake-up signal to the network-side device eight times in the first time window.

[0095] For another example, taking the service requirement of the uplink service as an example, the correspondence between the repetition number of the uplink wake-up signal and the priority of the uplink service is shown in Table 1.

[0096] Table 2

[0097] Based on Table 2, if the uplink service of the terminal-side device is non-urgent service for positioning request, the terminal-side device repeatedly sends the uplink wake-up signal to the network-side device 2 times within the first time window. If the uplink service of the terminal-side device is medium-urgent service for positioning request, the terminal-side device repeatedly sends the uplink wake-up signal to the network-side device 4 times within the first time window. If the uplink service of the terminal-side device is urgent service for positioning request, the terminal-side device repeatedly sends the uplink wake-up signal to the network-side device 6 times within the first time window.

[0098] Similarly, if the uplink service of the terminal-side device is non-urgent service for sensing, the terminal-side device repeatedly sends the uplink wake-up signal to the network-side device 8 times within the first time window. If the uplink service of the terminal-side device is medium-urgent service for sensing, the terminal-side device repeatedly sends the uplink wake-up signal to the network-side device 10 times within the first time window. If the uplink service of the terminal-side device is urgent service for sensing, the terminal-side device repeatedly sends the uplink wake-up signal to the network-side device 12 times within the first time window.

[0099] In another optional implementation, the uplink wake-up signal sent by the terminal-side device to the network-side device includes first information, and the first information is used to indicate the service requirement of the uplink service. In this way, the network-side device can directly determine the service requirement of the uplink service based on the detection of the first information in the uplink wake-up signal. As can be seen, the terminal-side device can notify the network-side device of the service requirement of the uplink service by sending the uplink wake-up signal carrying the first information. For example, the first information is bit information, and the bit information can be directly carried in the uplink wake-up signal to represent the service requirement of the uplink service.

[0100] For example, the service requirement of the uplink service is priority, and 3 bits are used to represent the priority of 0 level to 7 level, as shown in Table 3.

[0101] Table 3

[0102] The terminal-side device can determine the corresponding bit information from Table 3 based on the priority of the uplink service, and then carry the determined bit information in the uplink wake-up signal sent to the network-side device. For example, the priority of the uplink service is 5, and based on Table 3, the bit information corresponding to the priority of 5 is 101. Therefore, the uplink wake-up signal sent by the terminal-side device to the network-side device includes the first information, and the first information is 101.

[0103] For another example, the service requirement includes service type and priority, 3 bits are used to represent the priority of 0 level to 7 level, as shown in Table 3, and 2 bits are used to represent the service type, as shown in Table 4.

[0104] Table 4

[0105] For example, the first information in the uplink wake-up signal includes 5 bits, the first 2 bits are used to indicate the service type of the uplink service, and the last 3 bits are used to indicate the priority of the uplink service. The terminal-side device can determine the bit information corresponding to the service type of the uplink service from Table 4, determine the bit information corresponding to the priority of the uplink service from Table 3, and then carry the determined bit information in the uplink wake-up signal sent to the network-side device. For example, the service type of the uplink service is sensing, and the priority is 5; based on Table 4, the bit information corresponding to the service type of sensing is 10; based on Table 3, the bit information corresponding to the priority of 5 is 101; then, the uplink wake-up signal sent by the terminal-side device to the network-side device includes the first information and the first information is 10101.

[0106] S103, the network-side device detects the uplink wake-up signal from the terminal-side device.

[0107] In an optional embodiment, the network-side device detects the uplink wake-up signal from the terminal-side device in a third time window. The determination method of the third time window is not limited in the embodiments of the present application. The third time window can also be referred to as a wake-up signal occasion (WUS occasion) or a wake-up signal detection occasion.

[0108] Optionally, the third time window is predefined. For example, a predefined rule defines a fixed uplink time, the terminal-side device sends the uplink wake-up signal in the fixed uplink time, and the network-side device detects the uplink wake-up signal in the fixed uplink time. The fixed uplink time can be, for example, the first symbol of each slot.

[0109] Optionally, the third time window is determined based on the correspondence between the low-power wake-up signal and the uplink wake-up signal, and the low-power wake-up signal is a downlink wake-up signal sent by the network-side device to the terminal-side device. For example, the network-side device sends the low-power wake-up signal to the terminal-side device, and the terminal-side device sends the uplink wake-up signal after receiving the low-power wake-up signal from the network-side device. The network-side device detects the uplink wake-up signal within a period of time after sending the low-power wake-up signal to the terminal-side device, for example, as shown in FIG. 7, the network-side device detects the uplink wake-up signal within the next n slots after sending the low-power wake-up signal to the terminal-side device. Alternatively, the network-side device detects the uplink wake-up signal after a period of time from sending the low-power wake-up signal to the terminal-side device, for example, as shown in FIG. 8, the network-side device detects the uplink wake-up signal on the mth (m is a positive integer) slot after sending the low-power wake-up signal to the terminal-side device.

[0110] In an optional implementation, the uplink wake-up signal is transmitted at a time-frequency domain resource location of a PRACH. Specifically, the terminal-side device can send the uplink wake-up signal at the time-frequency domain resource location of the PRACH, and correspondingly, the network-side device can receive the uplink wake-up signal at the time-frequency domain resource location of the PRACH. Therefore, the network-side device can reuse the mechanism of the PRACH occasion to detect the uplink wake-up signal. For example, in combination with FIG. 9, FIG. 9 exemplarily shows a PRACH occasion, which includes PRACH occasion 0 to PRACH occasion 3. In the PRACH occasion 0, SSB1 and SSB4 are alternately arranged in the time domain. In the PRACH occasion 1, SSB1 and SSB5 are alternately arranged in the time domain. In the PRACH occasion 2, SSB2 and SSB6 are alternately arranged in the time domain. In the PRACH occasion 3, SSB3 and SSB7 are alternately arranged in the time domain.

[0111] In an optional implementation, the network-side device can determine the strongest beam sequence number by detecting the uplink wake-up signal at different frequency domain locations (for example, different frequency domain locations in the PRACH occasion), so as to reuse the beam direction of the strongest beam for subsequent transmission of the reference signal without repeated scanning. The binding relationship between the frequency domain location and the beam sequence number can be defined by a higher layer or configured through a radio resource control (RRC) signaling parameter, which can be one frequency point location corresponding to one beam sequence number (that is, one frequency point location corresponding to one beam), or multiple frequency point locations corresponding to one beam sequence number (that is, multiple frequency point locations corresponding to one beam).

[0112] For example, the frequency point location #1 corresponds to the beam sequence number of beam identity document (ID) #1, and the frequency point location #2 corresponds to the beam sequence number of beam ID #2. In the case where the terminal-side device notifies the network-side device of the relevant information (for example, the demand for uplink service) by repeatedly sending the uplink wake-up signal, if the terminal-side device repeatedly sends the uplink wake-up signal at the frequency point location #1, the network-side device will detect the uplink wake-up signal at the frequency point location #1, and then the network-side device determines that the strongest beam sequence number is beam ID #1, so as to reuse the beam direction corresponding to beam ID #1 for subsequent transmission of the reference signal. If the terminal-side device repeatedly sends the uplink wake-up signal at the frequency point location #2, the network-side device will detect the uplink wake-up signal at the frequency point location #2, and then the network-side device determines that the strongest beam sequence number is beam ID #2, so as to reuse the beam direction corresponding to beam ID #2 for subsequent transmission of the reference signal.

[0113] S104, the network-side device determines the service requirement of the uplink service based on the detected uplink wake-up signal.

[0114] It can be understood that the terminal-side device sends the uplink wake-up signal to the network-side device, which can not only wake up the network-side device, but also notify the network-side device of information related to the uplink wake-up signal (such as the service requirement of the uplink service, the type of the terminal-side device, etc.). Taking the uplink wake-up signal related to the service requirement of the uplink service as an example, the terminal-side device sends the uplink wake-up signal to the network-side device, which can notify the network-side device of the service requirement of the uplink service while waking up the network-side device, so that the network-side device determines the service requirement of the uplink service and then takes corresponding operations or opens corresponding functions to meet the service requirement of the uplink service, which can better save energy compared with the network-side device opening all function modules after receiving the wake-up signal.

[0115] In an optional implementation, the method further includes: the network-side device wakes up a function module corresponding to the service requirement of the uplink service.

[0116] Example 1: The service type of the uplink service includes a positioning request. The terminal-side device notifies the network-side device that the service type of the uplink service includes the positioning request by sending the uplink wake-up signal to the network-side device. After detecting the uplink wake-up signal, the network-side device can wake up a function module for the positioning request, so as to subsequently send a positioning reference signal (PRS) signal to the terminal-side device or prepare to receive the PRS signal from the terminal-side device to assist the terminal-side device in determining its own position.

[0117] Example 2: The service type of the uplink service includes sensing. The terminal-side device notifies the network-side device that the service type of the uplink service includes sensing by sending the uplink wake-up signal to the network-side device. After detecting the uplink wake-up signal, the network-side device can wake up a function module for sensing, so as to subsequently perform the sensing service in cooperation with the terminal-side device.

[0118] Example 3: The service type of the uplink service includes uplink data transmission. The terminal-side device notifies the network-side device that the terminal-side device is about to send uplink data by sending the uplink wake-up signal to the network-side device, which can contain the size of the transmitted data. After detecting the uplink wake-up signal, the network-side device can wake up a function module for allocating resources, so as to subsequently allocate corresponding time-frequency domain resources for data transmission.

[0119] Example 4: The service type of the uplink service includes uplink measurement quantity feedback. The terminal-side device sends an uplink wake-up signal to the network-side device to inform the network-side device that the terminal-side device is about to send the feedback of the uplink measurement quantity. After detecting the uplink wake-up signal, the network-side device can wake up the uplink reception function module, so as to subsequently detect the uplink measurement quantity on the corresponding time-frequency domain resource through the uplink reception function.

[0120] Example 5: The service type of the uplink service specifically includes random access. The terminal-side device sends an uplink wake-up signal to the network-side device to inform the network-side device that the terminal-side device is about to initiate random access. After detecting the uplink wake-up signal, the network-side device can wake up the function module for allocating resources and the detection module, so as to subsequently allocate PRACH resources, and detect the preamble on the predefined resource set and measure the TA.

[0121] Example 6: The service type of the uplink service specifically includes uplink scheduling request. The terminal-side device sends an uplink wake-up signal to the network-side device to inform the network-side device of the uplink scheduling request. After detecting the uplink wake-up signal, the network-side device can wake up the function module for allocating resources and the detection module, so as to subsequently allocate the corresponding time-frequency domain resource, and start detecting the uplink scheduling request information at the corresponding time.

[0122] Example 7: The uplink wake-up signal is related to the type of the terminal-side device. The terminal-side device sends an uplink wake-up signal to the network-side device to inform the network-side device of the type of the terminal-side device. After detecting the uplink wake-up signal, the network-side device can adopt different transmission powers for different terminal types. For example, if the terminal-side device is a RedCap terminal, the network-side device adopts a smaller transmission power to send a signal to the terminal-side device. If the terminal-side device is a normal UE, the network-side device adopts a larger transmission power to send a signal to the terminal-side device.

[0123] In an optional implementation, the method further includes: the network-side device sends second information to the terminal-side device, the second information corresponding to the uplink wake-up signal. The terminal-side device detects the second information from the network-side device within a second time window. It can be understood that, in the case that the network-side device detects the uplink wake-up signal within a third time window, the network-side device sends the second information to the terminal-side device to inform the terminal-side device that the network-side device has detected the uplink wake-up signal. It can also be understood that the second information corresponding to the uplink wake-up signal is also the feedback information sent by the network-side device in response to the detected uplink wake-up signal.

[0124] The second time window can be predefined or configured, without limitation. For example, the start time of the second time window can be a time interval after the terminal-side device transmits the uplink wake-up signal. For example, referring to FIG. 10, the network-side device transmits the second information when the uplink wake-up signal is detected in the third time window. The terminal-side device detects the second information in a time interval T offset after the start time of the third time window.

[0125] Optionally, the second information is downlink control information (DCI) for uplink scheduling, which can also be referred to as uplink DCI. For example, after detecting the uplink wake-up signal, the network-side device can perform uplink scheduling, including transmitting a physical downlink control channel (PDCCH) carrying the uplink DCI to the terminal-side device. The terminal-side device blindly detects the PDCCH in the second time window, and can determine that the network-side device correctly receives the uplink wake-up signal when the uplink DCI is detected in the PDCCH.

[0126] Optionally, the second information is downlink acknowledgment (DL ACK) information. As can be understood, after detecting the uplink wake-up signal, the network-side device transmits the DL ACK information to the terminal-side device for explicit feedback. The terminal-side device can determine that the network-side device correctly receives the uplink wake-up signal when the DL ACK information is detected in the second time window.

[0127] Optionally, the second information is carried in a low-power wake-up signal transmitted by the network-side device to the terminal-side device. As can be understood, after detecting the uplink wake-up signal, the network-side device transmits the low-power wake-up signal to the terminal-side device through the LR module. The terminal-side device can determine that the network-side device correctly receives the uplink wake-up signal when the low-power wake-up signal is detected in the second time window.

[0128] Optionally, the second information is carried in a chirp signal. For example, after detecting the uplink wake-up signal, the network-side device transmits a chirp signal carrying the DL ACK information to the terminal-side device. The terminal-side device can determine that the network-side device correctly receives the uplink wake-up signal when the chirp signal carrying the DL ACK information is detected in the second time window. Since the chirp signal is an analog signal, it is easy to detect and beneficial for the network-side device to detect the chirp signal with low complexity.

[0129] Optionally, the method further comprises: sending, by the terminal-side device, the uplink wake-up signal to the network-side device if the second information is not detected within the second time window. Understandably, if the second information is not detected within the second time window, the terminal-side device can consider that the network-side device has not correctly received the uplink wake-up signal, and thus sends the uplink wake-up signal to the network-side device again.

[0130] In an optional embodiment, if the network-side device does not detect the uplink wake-up signal from the terminal-side device within the third time window, the network-side device sends third information to the terminal-side device, the third information being downlink negative acknowledgement (NACK) information. If the terminal-side device detects the third information within the second time window, it can be determined that the network-side device has not correctly received the uplink wake-up signal, and thus sends the uplink wake-up signal to the network-side device again.

[0131] In summary, in the communication method, the terminal-side device sends the uplink wake-up signal to the network-side device, the uplink wake-up signal being related to the service requirement of the uplink service, the service requirement of the uplink service including one or more of the following: the service type of the uplink service, the data volume of the uplink service, or the priority of the uplink service. It can be seen that, in the method, the terminal-side device notifies the network-side device of the service requirement of the uplink service through the uplink wake-up signal, so that the network-side device determines the service requirement of the uplink service, and the network-side device can also wake up the module having the corresponding function based on the service requirement of the uplink service, enable the corresponding function, and adjust the transmission power to meet the service requirement of the uplink service, which can better save energy compared with turning on all the function modules when the network-side device receives the wake-up signal. In addition, the uplink wake-up signal transmitted between the terminal-side device and the network-side device is transmitted through the LR module, which has better real-time performance.
