Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method and related apparatus. Background Technology

[0002] With the continuous development of communication technology, network equipment faces challenges such as greater bandwidth, higher processing speeds, and more antennas. The primary challenge is power consumption. Therefore, researching green and energy-efficient communication technologies is particularly important.

[0003] Current energy-saving discussions have proposed on-demand transmission of System Information Block 1 (SIB1), the core idea of ​​which is to transform the periodic transmission of SIB1 into on-demand transmission. For example, network devices can pre-send uplink wake-up signals to terminal devices for configuration. Then, the terminal devices can send uplink wake-up signals back to the network devices when needed, triggering the network devices to send SIB1. The terminal devices can further use the random access channel configuration contained in the received SIB1 to complete random access, thereby saving power consumption of the network devices.

[0004] In one possible approach, the configuration of the uplink wake-up signal can reuse the random access channel configuration. However, not all parameters in the random access channel configuration are required for the configuration of the uplink wake-up signal. Therefore, directly reusing the random access channel configuration will result in higher transmission power consumption for the configuration of the uplink wake-up signal, which is not conducive to energy saving. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a communication method and related apparatus that can reduce the number of bits used in configuring the uplink wake-up signal, thereby reducing the transmission power consumption of the uplink wake-up signal configuration.

[0006] The following sections introduce this application from multiple perspectives. It is easy to understand that the implementation methods of these multiple aspects can be referenced from each other.

[0007] In a first aspect, embodiments of this application provide a communication method, which can be executed by a terminal device or by a functional component (e.g., a processor, chip, chip system, or circuit) within the terminal device. For ease of description, the following description uses a terminal device as the executing entity. The method includes: the terminal device receiving first information, the first information being used to configure an uplink wake-up signal. Then, the terminal device sends the uplink wake-up signal according to the first information. The first information multiplexes a random access channel configuration, and does not include the period of the random access response receive window configuration and / or the system information request configuration.

[0008] In the above implementation, the first information, based on the reuse of the existing random access channel configuration, does not include the period of the random access response receiving window configuration and / or system information request configuration. This can reduce the number of bits used for the configuration of the uplink wake-up signal, thereby reducing the transmission overhead of the uplink wake-up signal configuration and reducing the power consumption generated by the terminal device when receiving the configuration.

[0009] In conjunction with the first aspect, in one possible implementation, the method further includes: the terminal device sending a random access channel based on the first information.

[0010] In the above implementation, the terminal device can directly send the random access channel based on the first information, that is, the first information simultaneously configures the uplink wake-up signal and random access, instead of sending the random access channel through the random access channel configuration included in SIB1 as in the prior art, thus improving the random access efficiency.

[0011] In conjunction with the first aspect, in one possible implementation, for cases where the first information does not include the receiving window configuration of the random access response, and for cases where the first information simultaneously configures random access, the method further includes: the terminal device determining the receiving window of the random access response based on the receiving window of SIB1.

[0012] In conjunction with the first aspect, in one possible implementation, the receive window of SIB1 is located in the same position as the receive window of the random access response.

[0013] In conjunction with the first aspect, in one possible implementation, the receiving window of SIB1 is located adjacent to the receiving window of the random access response.

[0014] In conjunction with the first aspect, in one possible implementation, there is an interval (or time offset) between the position of the receiving window of SIB1 and the receiving window of the random access response. The method further includes: the terminal device determining the receiving window of the random access response based on the receiving window of SIB1 and the time offset.

[0015] In the above implementation, since the terminal device can determine the receiving window of the random access response based on the receiving window of SIB1, it is not necessary to configure the receiving window of the random access response when configuring the uplink wake-up signal through the first information, thereby reducing the configuration of the uplink wake-up signal.

[0016] In conjunction with the first aspect, in one possible implementation, the method further includes: the terminal device receiving a master information block (MIB) message. The MIB message includes the time window position for receiving SIB1, i.e., the receiving window of SIB1, or the time-domain information of SIB1.

[0017] In conjunction with the first aspect, in one possible implementation, for cases where the first information does not include the system information request configuration period, the method further includes: the terminal device receiving SIB1. Wherein, SIB1 includes the system information request configuration period.

[0018] In conjunction with the first aspect, in one possible implementation, when the first information does not include the period for configuring the system information request, the method further includes: the terminal device receiving a random access response. The random access response includes the period for configuring the system information request.

[0019] In conjunction with the first aspect, in one possible implementation, the first information is carried on a synchronization signal.

[0020] Secondly, embodiments of this application provide a communication method, which can be executed by a network device or by a functional component (e.g., a processor, chip, chip system, or circuit) within the network device. For ease of description, the following description uses a network device as the executing entity. The method includes: the network device determining first information; and then, the network device sending the first information. The first information is used to configure an uplink wake-up signal. The first information multiplexes a random access channel configuration, and does not include the period of the random access response receive window configuration and / or the system information request configuration.

[0021] In conjunction with the second aspect, in one possible implementation, the first information is also used to configure a random access channel, and the method further includes: the network device receiving the random access channel according to the first information.

[0022] In conjunction with the second aspect, in one possible implementation, for cases where the first information does not include the receive window configuration for a random access response, and for cases where the first information simultaneously configures random access, the method further includes: the network device determining the receive window for the random access response based on the receive window of SIB1.

[0023] In conjunction with the second aspect, in one possible implementation, the method further includes: the network device sending a MIB message. The MIB message includes the time window position for receiving SIB1, i.e., the receiving window of SIB1, or the time-domain information of SIB1.

[0024] In conjunction with the second aspect, in one possible implementation, for cases where the first information does not include the system information request configuration period, the method further includes: the network device sending SIB1. Here, SIB1 includes the system information request configuration period.

[0025] In conjunction with the second aspect, in one possible implementation, for cases where the first information does not include the system information request configuration period, the method further includes: the network device sending a random access response. The random access response includes the system information request configuration period.

[0026] The second aspect has some possible implementation methods and beneficial effects that can be referred to in the first aspect, and will not be elaborated further.

[0027] Thirdly, embodiments of this application provide a communication method, which can be executed by a terminal device or by a functional component (e.g., a processor, chip, chip system, or circuit) within the terminal device. For ease of description, the following description uses a terminal device as the executing entity. The method includes: the terminal device receiving first information, which is used to configure an uplink wake-up signal. Then, the terminal device sends the uplink wake-up signal according to the first information. The first information multiplexes a random access channel configuration, and the first information does not include at least one of the following: a random access response reception window configuration, the number of repetitions of the random access opportunity in the frequency domain, a portion of the spatial resource configuration included in the random access channel resources, or a portion of the random access preamble configuration.

[0028] In the above implementation, the first information, based on reusing the existing random access channel configuration, does not include at least one of the following: the receiving window configuration of the random access response, the number of repetitions of the random access timing in the frequency domain, the spatial resource configuration included in the random access channel resources, or the configuration of the random access preamble. This can reduce the number of bits used in the configuration of the uplink wake-up signal, thereby reducing the transmission overhead of the uplink wake-up signal configuration and reducing the power consumption generated when the terminal device receives the configuration.

[0029] In conjunction with the third aspect, in one possible implementation, the method further includes: the terminal device determining the receiving window of the random access response based on the receiving window of SIB1.

[0030] In conjunction with the third aspect, in one possible implementation, the receiving window of SIB1 is located in the same position as the receiving window of the random access response.

[0031] In conjunction with the third aspect, in one possible implementation, the receiving window of SIB1 is adjacent to the receiving window of the random access response.

[0032] In conjunction with the third aspect, in one possible implementation, there is an interval (or time offset) between the position of the receiving window of SIB1 and the receiving window of the random access response. The method further includes: the terminal device determining the receiving window of the random access response based on the receiving window of SIB1 and the time offset.

[0033] In the above implementation, since the terminal device can determine the receiving window of the random access response based on the receiving window of SIB1, it is not necessary to configure the receiving window of the random access response when configuring the uplink wake-up signal through the first information, thereby reducing the configuration of the uplink wake-up signal.

[0034] In conjunction with the third aspect, in one possible implementation, the method further includes: the terminal device receiving a MIB message. The MIB message includes the time window position for receiving SIB1, i.e., the receiving window of SIB1, or the time-domain information of SIB1.

[0035] In conjunction with the third aspect, in one possible implementation, the method further includes: the terminal device receiving a random access channel configuration and transmitting a random access channel according to the random access channel configuration. Here, the random access channel configuration is all configurations available in the existing random access channel configurations.

[0036] In the above implementation, the terminal device can receive random access channel configuration so that it can subsequently initiate random access.

[0037] In conjunction with the third aspect, in one possible implementation, the random access channel configuration is carried on SIB1. Here, SIB1 may include the complete random access channel configuration in existing schemes.

[0038] Fourthly, embodiments of this application provide a communication method, which can be executed by a network device or by a functional component (e.g., processor, chip, chip system, or circuit) within the terminal network device. For ease of description, the following description uses a network device as the executing entity. The method includes: the network device determining first information. Then, the network device sends the first information to the terminal device. The first information is used to configure an uplink wake-up signal. The first information multiplexes a random access channel configuration, and the first information does not include at least one of the following: a random access response reception window configuration, the number of repetitions of the random access opportunity in the frequency domain, a portion of the spatial resource configuration included in the random access channel resources, or a portion of the random access preamble configuration.

[0039] In conjunction with the fourth aspect, in one possible implementation, the method further includes: the network device determining the receive window of the random access response based on the receive window of SIB1.

[0040] In conjunction with the fourth aspect, in one possible implementation, the method further includes: the network device sending a MIB message to the terminal device. The MIB message includes the time window position for receiving SIB1, i.e., the receiving window of SIB1, or the time-domain information of SIB1.

[0041] In conjunction with the fourth aspect, in one possible implementation, the method further includes: the network device receiving an uplink wake-up signal and then sending a random access channel configuration. Here, the random access channel configuration is used to configure a random access channel, and the random access channel configuration is all the configurations in the existing random access channel configurations.

[0042] In the above implementation, after the network device receives the uplink wake-up signal and is woken up, it can send a random access channel configuration to the terminal device, which can ensure that random access can be completed subsequently.

[0043] In conjunction with the third or fourth aspect, in one possible implementation, the configuration of the random access preamble may include at least one of the following: the number of random access preambles, the format of the random access preambles, the cyclic shift number of the random access preambles, or the root sequence index of the random access preambles.

[0044] In conjunction with the third or fourth aspect, in one possible implementation, the first information includes the number of random access opportunities in the time domain.

[0045] In conjunction with the third or fourth aspect, in one possible implementation, the number of random access opportunities in the time domain is 1, or in other words, the random access opportunity has only one position in the time domain.

[0046] In the above implementation, when configuring the uplink wake-up signal through the first information, although it is still necessary to configure the number of random access opportunities in the time domain, only one random access opportunity needs to be configured in the time domain, instead of configuring multiple random access opportunities in the time domain as in the existing random access configuration. Thus, when configuring the uplink wake-up signal through the first information, it is beneficial to reduce the number of bits used for configuring the uplink wake-up signal.

[0047] In conjunction with the third or fourth aspect, in one possible implementation, the first information includes the number of random access opportunities in the frequency domain.

[0048] In conjunction with the third or fourth aspect, in one possible implementation, the number of random access opportunities in the frequency domain is 1, or in other words, the random access opportunity has only one position in the frequency domain.

[0049] In the above implementation, when configuring the uplink wake-up signal through the first information, although it is still necessary to configure the number of random access opportunities in the frequency domain, only one random access opportunity needs to be configured in the frequency domain, instead of configuring multiple random access opportunities in the frequency domain as in the existing random access configuration. Thus, when configuring the uplink wake-up signal through the first information, it is beneficial to reduce the number of bits used for configuring the uplink wake-up signal.

[0050] In conjunction with the third or fourth aspect, in one possible implementation, the first information is carried on a synchronization signal.

[0101] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0102] In this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. In the textual description of this application, the character " / " generally indicates an "or" relationship between the preceding and following related objects; in the formulas of this application, the character " / " indicates a "division" relationship between the preceding and following related objects. "Including at least one of A, B, and C" can mean: including A; including B; including C; including A and B; including A and C; including B and C; including A, B, and C.

[0103] The technical solutions provided in this application can be applied to various communication systems, such as Long Term Evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, 5th generation (5G) systems, or new radio (NR) systems. In addition, they can also be applied to future communication systems, such as 6th generation (6G) communication systems.

[0104] The system architecture used in the embodiments of this application is described below. It should be noted that the system architecture and business scenarios described in this application are for the purpose of more clearly illustrating the technical solutions of this application, and do not constitute a limitation on the technical solutions provided in this application. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this application are also applicable to similar technical problems.

[0105] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of this application. It should be understood that... Figure 1 The illustration shows a terrestrial communication system to which the technical solution provided in this application is applicable. For example... Figure 1 As shown, the communication system 10 may include a radio access network (RAN) 100. RAN 100 includes at least one RAN node (e.g., Figure 1 110a and 110b in the above) and at least one terminal (such as Figure 1 (120a-120j in the original text). RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 1 (Not shown in the image). The terminal connects to the RAN node wirelessly. Optionally, the communication system 10 may also include a core network (CN) 130. The RAN node connects to the core network 130 wirelessly or via a wired connection. The core network equipment in the core network 130 and the RAN node in the RAN 100 may be different physical devices, or they may be the same physical device integrating core network logical functions and radio access network logical functions. Optionally, the communication system 10 may also include the Internet 140.

[0106] RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as 4G, 5G mobile communication systems, or future-oriented evolution systems. RAN 100 can also be an open access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. RAN 100 can also be a communication system that integrates two or more of the above systems.

[0107] exist Figure 1 In the communication system shown, RAN nodes, sometimes also called access network devices, network equipment, RAN entities, or access nodes, constitute part of the communication system and are used to help terminals achieve wireless access. Multiple RAN nodes in communication system 10 can be of the same type or different types. In some scenarios, the roles of RAN nodes and terminals are relative, for example... Figure 1 Network element 120i can be a helicopter or a drone, and it can be configured as a mobile base station. For terminals 120j that access RAN 100 through network element 120i, network element 120i is a base station. However, for base station 110a, network element 120i is a terminal. RAN nodes and terminals are sometimes referred to as communication devices, for example... Figure 1 Network elements 110a and 110b can be understood as communication devices with base station functions, while network elements 120a-120j can be understood as communication devices with terminal functions.

[0108] In one possible scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next-generation NodeB (gNB), a base station in a future mobile communication system, or an access node in a WiFi system, etc. Figure 1 110a), micro base stations or indoor stations (such as Figure 1 The RAN node can be a relay node or donor node (as described in section 110b), or a wireless controller in a CRAN scenario. Optionally, the RAN node can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU). All or part of the functions of the RAN node in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (e.g., a cloud platform). The RAN node can also be equipped with communication modules, circuits, or chips that perform corresponding communication functions. The RAN node can also be configured with program instructions for performing corresponding communication functions and corresponding program instructions. The RAN node in this application can also be a logical node, logical module, or software capable of implementing all or part of the RAN node functions.

[0109] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with different RAN nodes each implementing a portion of the base station's functions. For example, RAN nodes can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0110] exist Figure 1In the communication system shown, the terminal can be a device or module that accesses the communication system and has corresponding communication functions. The terminal can also be called a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, transportation vehicles with wireless communication capabilities, communication modules, etc. The embodiments of this application do not limit the device form of the terminal. The terminal typically contains a communication module, circuit, or chip that performs the corresponding communication function. The terminal can also be configured with program instructions for performing the corresponding communication function.

[0111] Please see Figure 2 , Figure 2 This is a schematic diagram of the architecture of another communication system provided in an embodiment of this application. It should be understood that... Figure 2 The illustration shows a non-terrestrial communication system, or satellite communication system, to which the technical solution provided in this application is applicable. For example... Figure 2 As shown, the communication system 20 may include at least one terminal device 210 and at least one network device 220. Exemplarily, terminal device 210 may include terminal device 210a and / or terminal device 210b, and network device 220 may include satellite 220a and / or satellite 220b. Network device 220 may communicate directly with terminal device 210 or via a relay station, such as a relay satellite. It should be understood that network device 220 may include one or more satellites. Satellites can provide communication services, navigation services, and positioning services to terminal devices through multiple beams. Satellites use multiple beams to cover the service area, and different beams can communicate through one or more of time division, frequency division, and space division. Inter-satellite links can be established between satellites, and satellites can process and forward data according to protocols. The communication system 20 may also include a connection device 230, such as a gateway, wherein network device 220 can communicate with connection device 230. Optionally, the communication system 20 may also include a core network 240, and the connection device 230 may communicate with the core network 240. It should be understood that... Figure 2This is just an example. In real-world scenarios, communication system 20 may also include other types of network devices and / or other types of terminal devices, or it may include more or fewer satellites and more or fewer terminal devices. In possible scenarios, network devices may also include other non-ground devices (or flying devices), such as drones.

[0112] In this application embodiment, the satellite communication system may include a transparent transmission mode and a non-transparent transmission mode. Transparent transmission, also known as bend-tube relay transmission, means that the signal only undergoes frequency conversion and signal amplification on the satellite. Non-transparent transmission can be called regenerative (on-board access / processing) transmission, meaning the satellite has some or all of the base station functions. The satellite involved in this application embodiment refers to an artificial satellite. The satellite can be a satellite base station, or it may include an orbital receiver or repeater for relaying information, or network equipment carried on the satellite; the satellite can be a low Earth orbit (LEO) satellite, a middle Earth orbit (MEO) satellite, a highly elliptical orbit (HEO) satellite, a geostationary earth orbit (GEO) satellite, or a non-geostationary orbit (NGEO) satellite, etc. This application does not impose any limitations on this. It should be understood that the solutions in this application embodiment can also be applied to other communication systems, and the corresponding names can be replaced by the names of the corresponding functions in other communication systems.

Network devices can also be servers, wearable devices, or vehicle-mounted devices. Network devices can also be network devices in cloud radio access network (CRAN) scenarios. Network equipment can also be network equipment in non-terrestrial networks (NTNs), such as relay satellites or satellites with base station functions. Network equipment can contain one or more co-located or non-co-located TRPs.

Terminal devices can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; they can also be deployed on water (such as on ships); and they can also be deployed in the air (e.g., on airplanes, balloons, and satellites).

For example, a terminal device can support communication with base stations supporting LTE networks, as well as base stations supporting 5G networks, and can also support dual connectivity with both LTE and 5G network base stations.

[0115] It should be understood that, in combination Figure 1 The communication system 10 shown in this application embodiment can be specifically implemented by the RAN node and the terminal in the communication system 10 working together. Combined with... Figure 2 The communication system 20 shown in this application can be specifically implemented by the terminal device 210 and the network device 220 working together within the communication system 20. For ease of understanding, the network device and the terminal device will be used as examples in the embodiments of this application.

[0116] It should be noted that in this application, the network devices and terminal devices can be fixed in location or mobile. Specifically, the network devices and terminal devices can be deployed on land, including indoors, handheld, or vehicle-mounted, or on water, or in the air on airplanes, balloons, and satellites. This application does not impose specific limitations on the application scenarios of the network devices and terminal devices.

[0117] Network devices and terminal devices, as well as terminal devices communicating with each other, can communicate using licensed spectrum, unlicensed spectrum, or both simultaneously. They can also communicate using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously.

Similarly, the functions of the terminal device can be executed by modules (such as chips or modems) within the terminal, or by a device that includes terminal device functions.

[0119] It should be understood that multiple terminal devices can exist in a communication system. That is, a network device can establish communication connections with multiple terminal devices. Similarly, multiple network devices can exist in a communication system. That is, a terminal device can simultaneously establish communication connections with multiple network devices. In the embodiments of this application, no specific limitation is made on the number of network devices and terminal devices in the communication system. For ease of understanding, the following description uses one network device and one terminal device as an example to illustrate the communication method provided in this application.

[0120] To facilitate understanding of this application, some terms or concepts used in this application will be explained below.

[0121] 1. Random Access (RA) Procedure

[0122] The random access procedure refers to the process from when a terminal device sends a random access preamble to attempt to access a network device, until a basic signaling connection is established with the network device. Random access is a crucial step in mobile communication systems and the final step in establishing a communication link between the terminal device and the network device. Through the random access procedure, the terminal device can establish a connection with the cell and achieve uplink synchronization. The random access procedure can be triggered by certain events; for example, the terminal device may initiate access from an idle state, perform a radio resource control (RRC) connection recovery procedure from an inactive state, or perform an RRC connection reconstruction procedure. It should be noted that in this application's embodiments, the random access preamble may also be referred to as a random access preamble sequence, random access preamble, preamble code, or preamble sequence, and this application is not limited to these terms.

[0123] Random access procedures can be divided into contention-based and non-contention-based procedures. In contention-based random access procedures, the random access preamble is generated by the terminal device. Different terminal devices may generate conflicting random access preambles (i.e., different terminal devices use the same random access preamble to access the network), requiring the network device to resolve access conflicts through contention. In non-contention-based random access procedures, the random access preamble is assigned to the terminal device by the network device, avoiding conflicts between different terminal devices. This application primarily uses a contention-based random access procedure as an example for illustration.

[0124] If a terminal device needs to send uplink data or signaling when there are no uplink resources, such as an RRC reconstruction request, RRC establishment request, or RRC link resume request, it needs to trigger a random access procedure. During this procedure, the terminal device can request network resources and use them for data transmission, while avoiding conflicts with other terminal devices. The following will combine... Figure 3 An example illustration is provided for a contention-based random access procedure. For example... Figure 3 As shown, the random access procedure may include the following steps:

[0125] S301, the terminal device sends a random access preamble to the network device. Correspondingly, the network device receives the random access preamble.

[0126] The random access preamble, also known as message 1 (msg1) or random access request, or in other words, msg1 includes the random access preamble. The purpose of the random access preamble is to notify the network device of a random access request and to enable the network device to calculate the transmission delay between itself and the terminal device. This allows the network device to calibrate uplink timing and communicate the calibration information to the terminal device via timing advance (TA) time adjustment information.

[0127] It should be noted that before sending the random access preamble, the terminal device needs to select a synchronization signal and physical broadcast channel block (SSB). Then, based on the system message received from the network device and the index of the selected SSB, the terminal device selects a specific random access occasion (RO) associated with that SSB to send the preamble (or preamble sequence, i.e., msg1). After determining the RO, the terminal device randomly selects a preamble and sends it within the selected RO.

[0128] The selection of an SSB index by the terminal device can be understood as each SSB corresponding to a beam. The terminal device obtains the reference signal receiving power (RSRP) threshold from the protocol and selects a beam with an RSRP greater than the threshold. Generally, the terminal device selects the beam with the highest RSRP from the beams, and this beam corresponds to one SSB.

[0129] RO can be understood as the time-frequency resource used by terminal devices for random access. Network devices can pre-configure the correspondence between RO and SSB. A maximum of 64 preambles can be transmitted simultaneously on a single RO. The terminal device selects one of the 64 preambles to send. Then, the terminal device sends the preamble to the network device, which is carried by the physical random access channel (PRACH).

[0130] S302, the network device sends a random access response to the terminal device. Correspondingly, the terminal device receives the random access response.

[0131] After detecting a random access preamble, the network device sends a random access response (RAR) to the terminal device. This RAR is also known as message 2 (msg2). The RAR may include the number of the received random access preamble, TA time adjustment information, uplink (UL) grant, and temporary cell radionetwork temporary identity (TC-RNTI). The uplink grant is used to indicate the transmission resources for message 3 (msg3).

[0132] S303, the terminal device sends uplink signaling to the network device to establish an RRC connection. Correspondingly, the network device receives the uplink signaling.

[0133] The uplink signaling, also known as msg3, typically includes RRC signaling and a media access control-control element (MAC-CE). The RRC signaling can vary depending on the scenario, for example, it may be for an RRC connection establishment request, an RRC re-establishment request, or an RRC recovery request.

[0134] msg3 is transmitted on the time-frequency resources specified in msg2 and carried by the Physical Uplink Shared Channel (PUSCH), which can carry information such as the terminal device's unique user identifier. Simultaneously, the terminal device can use the TC-RNTI allocated in msg2 to initiate a collision resolution detection message.

[0135] S304, the network device sends a conflict resolution message to the terminal device. Correspondingly, the terminal device receives the conflict resolution message.

[0136] The conflict resolution message, also known as message 4 (msg4) or contention resolution message, is primarily used for conflict resolution. When multiple terminal devices attempt to access the network simultaneously, it determines which terminal device will be selected for random access. The network device carries the unique user identifier from msg3 in the conflict resolution message to identify the terminal device that successfully accesses the network, while other terminal devices that fail to access the network will re-initiate random access.

[0137] For example, if two terminal devices choose to send the same preamble sequence at the same time, both devices will send msg3 simultaneously, resulting in a collision. During uplink resource detection, the network device can only detect uplink data sent by one terminal device. In the collision resolution message, the network device truncates the first X bits of the uplink data sent by the single terminal device and schedules it to the terminal device via TC-RNTI. Upon receiving this message, the terminal checks if it matches its own msg3. If they match, the connection is considered successful; otherwise, the connection fails.

[0138] 2. Random Access Channel (RACH) Configuration

[0139] Before entering contention-based random access, the terminal device needs to obtain the random access-related configuration information contained in system information block (SIB)1, namely the random access channel configuration, as follows:

[0140] (1) Time-frequency-space resource allocation:

[0141] 1-1: Time-domain resource configuration specifies the timing of random access preamble transmission in the time domain. Specifically, this may include frame structure ratios, the position of the random access timing in the time domain, and the configuration of the random access response reception window. Among these:

[0142] Frame structure allocation is used to specify the uplink and downlink frame structure. For RACH, the frame structure allocation determines the location and number of time slots and symbols used for random access within a radio frame.

[0143] The temporal location of a random access opportunity includes the frame, subframe, time slot, and symbol in which it occurs, and can be carried by the prach-ConfigurationIndex cell. It should be noted that the number of random access opportunities in the temporal domain can be determined based on their specific location.

[0144] The random access response receive window configuration is used by the terminal device to receive the msg2 (i.e., random access response) sent by the network device at a specified time domain location. It can be carried by the ra-ResponseWindow cell.

[0145] 1-2: Frequency domain resource configuration clarifies the location and bandwidth occupied by the random access signal in the frequency domain. Specifically, this may include subcarrier spacing and frequency domain bandwidth, the location of the random access opportunity in the frequency domain, and the number of repetitions of the random access opportunity in the frequency domain. Among these:

[0146] The location of the random access opportunity in the frequency domain, including its starting position, is determined by the offset of the starting position of the resource block (RB) relative to the starting position of the uplink common bandwidth part (BWP) in the frequency domain. This offset can be carried by the msg1-FrequencyStart cell. It should be noted that the number of random access opportunities in the frequency domain can be determined based on their specific location.

[0147] The number of times a random access opportunity is repeated in the frequency domain indicates the number of times a random access opportunity can be reused in the frequency domain, and it can be carried by msg1-FDM cells.

[0148] 1-3: Spatial resource configuration, related to beam management, such as instructing terminal equipment to select a suitable beam to initiate RACH based on the measured SSB beam, which can be carried by ssb-perRACH-Occasion cells.

[0149] (2) Preamble-related configuration (code field resources):

[0150] 2-1: Number of random access preambles, indicating the total number of random access preambles available.

[0151] 2-2: Random access preamble format related configuration, which may include the format of the random access preamble, the cyclic shift value of the random access preamble, the root sequence index of the random access preamble, and the constraint set configuration of the random access preamble. Among them:

[0152] The format of the random access preamble refers to the specific structure and parameter settings of the signal sequence sent by the terminal device to the network device to request random access during the random access process. It specifies the length, value range, generation method, and distribution of the sequence on time and frequency resources.

[0153] The cyclic shift value of the random access preamble is used to determine how many random access preambles can be generated by a root index. This value is determined by the cell radius.

[0154] The root sequence index of the random access preamble is used to generate the root sequence index of the random access preamble. The root sequence index of each cell must be the same to ensure that the sequence generated by the terminal device can be demodulated in any cell within a region.

[0155] The restriction set configuration for the random access preamble is used to configure the cyclic shift value for low-speed and high-speed cells.

[0156] (3) Power domain resource allocation:

[0157] 3-1: The transmit power of the preamble sequence is used by the terminal equipment to determine the transmit power of the preamble sequence. However, it needs to be used in conjunction with the SSB (Side Buffer Block). That is, the terminal equipment obtains the path loss after measuring the SSB, and then determines the transmit power by combining this information cell. The transmit power of the preamble sequence can be carried by the preambleReceivedTargetPower information cell.

[0158] 3-2: Power ramping step size, used to determine the step size used by the terminal equipment when adjusting the transmission power, which can be carried by the powerRampingStep cell.

[0159] (4) Other resource allocation:

[0160] 4-1: System information request configuration period, used to determine the period for requesting system information configuration, which can be carried by the si-RequestPeriod information element.

[0161] 4-2: Maximum number of preamble transmissions: This determines the maximum number of times the preamble sequence can be transmitted before a random access failure. It can be carried by a preambleTransMax cell. It should be noted that the maximum number of preamble transmissions can also indicate the number of retransmissions of the preamble sequence, or the number of repetitions of the preamble sequence.

[0162] 3. Synchronization signal

[0163] Synchronization signals are used in communication systems to synchronize the time and frequency of the transmitting and receiving parties. They enable the receiving end to accurately determine the timing and frequency of the transmitting end's signal, thereby correctly demodulating and decoding the data.

[0164] Synchronization signals may include SSBs, which consist of the physical broadcast channel (PBCH), the primary synchronization signal (PSS), the secondary synchronization signal (SSS), and reference signals used for power control and channel estimation. The PSS and SSS are used to achieve frequency and time synchronization of the cell, while the PBCH carries key system information, such as SIB1 scheduling-related information.

[0165] Current energy-saving discussions have proposed on-demand SIB1 transmission, the core idea of ​​which is to transform the periodic transmission of SIB1 into on-demand transmission. For example, network devices pre-send uplink wake-up signal configurations to terminal devices, which can then send uplink wake-up signals to the network devices when needed, triggering the network devices to send SIB1. The terminal devices can further use the random access channel configuration contained in the received SIB1 to complete random access, thereby saving power consumption of the network devices. In existing technologies, the uplink wake-up signal configuration reuses the random access channel configuration, which results in high transmission power consumption for the uplink wake-up signal configuration, hindering energy saving. Therefore, the technical problem this application aims to solve is: how to reduce the transmission power consumption of the uplink wake-up signal configuration.

[0166] To address the aforementioned issues, this application provides a communication method that reduces unnecessary configurations when configuring the uplink wake-up signal using a multiplexed random access channel configuration. This means fewer configurations can be used, thereby reducing the number of bits used for uplink wake-up signal configuration and thus lowering transmission power consumption when transmitting the uplink wake-up signal configuration.

[0167] Based on the above, the communication method of this application embodiment will be described below by way of example.

[0168] Please see Figure 4 , Figure 4 This is a flowchart illustrating a communication method provided in an embodiment of this application. It should be understood that... Figure 4 The communication method shown can be applied to Figure 1 or Figure 2 The communication system shown is illustrated. Specifically, the communication method can be interactively executed by a network device and a terminal device. It should be noted that the method executed by the network device in this application can also be interactively executed by a chip, chip system, or processor within the network device; similarly, the method executed by the terminal device in this application can also be interactively executed by a chip, chip system, or processor within the terminal device, and this application does not impose specific limitations in this regard. Figure 4 As shown, the communication method may include the following steps:

[0169] S401, the network device determines the first information.

[0170] Specifically, the first information can be used to configure the uplink wake-up signal, or in other words, to configure the resources for the uplink wake-up signal. The first information can reuse the random access channel configuration from existing schemes, but compared to existing random access channel configurations, the first information may not include at least one of the following: the receiver window configuration of the random access response, the number of repetitions of the random access opportunity in the frequency domain, the spatial resource configuration included in the random access channel resources, or a portion of the random access preamble configuration.

[0171] Optionally, the configuration of the random access preamble may include at least one of the following: the number of random access preambles, the format of the random access preamble, the cyclic shift number of the random access preamble, or the root sequence index of the random access preamble.

[0172] In other words, the first information may include at least the frame structure ratio in the random access channel configuration, the position of the random access opportunity in the time domain, the subcarrier spacing, the frequency domain bandwidth, the position of the random access opportunity in the frequency domain, the constraint set configuration, the transmit power of the random access preamble, the power ramp step size, the period of the system information request configuration, and the maximum number of transmissions of the random access preamble.

[0173] It should be noted that, in possible scenarios, the first information may also include at least one of the following: the receive window configuration of the random access response, the number of repetitions of the random access opportunity in the frequency domain, the spatial resource configuration included in the random access channel configuration, the number of random access preambles, the format of the random access preamble, the cyclic shift number of the random access preamble, or the root sequence index of the random access preamble. However, it should be understood that the first information does not include all of the aforementioned configurations simultaneously.

[0174] To facilitate understanding, the following sections will explain the configurations that may not be included in the first piece of information and the reasons why.

[0175] The random access response reception window, also known as the time window for a terminal device to receive a random access response, refers to the allowed time range from when the terminal device sends the random access preamble to when it receives the random access response sent by the network device during the random access process.

[0176] In a possible implementation, the terminal device and network device can determine the receiving window of the random access response based on the receiving window of SIB1. Therefore, when configuring the uplink wake-up signal through the first information, the time window position for receiving the random access response does not need to be configured, that is, the first information may not include the configuration of the receiving window of the random access response.

[0177] It should be noted that network devices can indicate the time window position for receiving SIB1, or the receiving window of SIB1, or the time domain information of SIB1, to terminal devices through SSB or the master information block (MIB) message carried by SSB.

[0178] Optionally, there may be a certain positional relationship between the SIB1 receive window and the random access response receive window. This positional relationship may be predefined by the protocol or pre-configured by the network device. For example, the positions of the SIB1 receive window and the random access response receive window may be the same or adjacent, or there may be a certain time offset between them. This time offset may be agreed upon by the protocol or pre-configured by the network device.

[0179] The following section will illustrate possible implementations of determining the receive window of the random access response based on the SIB1 receive window, taking into account three possible positional relationships between the SIB1 receive window and the random access response receive window.

[0180] In Method 1, when the receiving window of SIB1 is the same as the receiving window of the random access response, the terminal device and the network device can directly use the receiving window of SIB1 as the receiving window of the random access response.

[0181] Method 2: When the SIB1 receiving window and the random access response receiving window are adjacent, the terminal device and network device can use the end time of the SIB1 receiving window as the start time of the random access response receiving window. Then, the terminal device and network device can determine the end time of the random access response receiving window based on its size and start time, thus determining the position of the random access response receiving window.

[0182] Method 3: When there is a time offset between the SIB1 receive window and the random access response receive window, the terminal device and network device can determine the random access response receive window based on the SIB1 receive window and the time offset. Specifically, the terminal device and network device can determine the start time of the random access response receive window based on the end time of the SIB1 receive window and the time offset. Then, the terminal device and network device can determine the end time of the random access response receive window based on its size and start time, thus determining the position of the random access response receive window.

[0183] Optionally, the size of the receiving window in the random access response can be the same as or different from the size of the receiving window in SIB1. Specifically, the size of the receiving window in the random access response can be predetermined by the protocol or pre-configured by the network device. This application does not limit this.

[0184] Regarding the first information, which does not include the number of times the random access opportunity repeats in the frequency domain, it should be noted that... Figure 4In the illustrated embodiment, the uplink wake-up signal configured by the first information is used to wake up the network device, so that the network device sends SIB1 to the terminal device after being woken up. SIB1 is broadcast to all terminal devices in the communication system; that is, SIB1 is a common signal that all terminal devices in the communication system can receive. Therefore, the terminal device only needs to send an uplink wake-up signal once to wake up the network device to obtain SIB1, instead of repeatedly sending multiple uplink wake-up signals. It can be understood that the uplink wake-up signal transmission timing only needs to be repeated once in the frequency domain, or in other words, the uplink wake-up signal transmission timing only needs to be one in the frequency domain. It should be understood that when the first information reuses the existing random access channel configuration, the random access timing included in the random access channel configuration can be used to send the uplink wake-up signal; therefore, the transmission timing of the uplink wake-up signal is the random access timing. Thus, the random access timing does not need to be repeated in the frequency domain; that is, the number of repetitions of the random access timing in the frequency domain is 1. In this way, when configuring the uplink wake-up signal through the first information, it is not necessary to configure the number of repetitions of the random access opportunity in the frequency domain. It should be understood that not configuring the number of repetitions of the random access opportunity in the frequency domain means that the number of repetitions of the random access opportunity in the frequency domain is 1.

[0185] Optionally, when reusing the existing random access channel configuration, the first information may still include the number of random access opportunities in the time domain, but the number of random access opportunities in the time domain may be 1, or in other words, there may only be one location of the random access opportunity in the time domain.

[0186] It should be noted that, as can be seen from the above, the terminal device only needs to send an uplink wake-up signal once to wake up the network device. Therefore, it can be understood that only one uplink wake-up signal needs to be sent in the time domain. In other words, there is only one time domain position corresponding to the random access opportunity, or the number of random access opportunities in the time domain can be 1.

[0187] In the above implementation, when configuring the uplink wake-up signal through the first information, although it is still necessary to configure the number of random access opportunities in the time domain, only one random access opportunity needs to be configured in the time domain, instead of configuring multiple random access opportunities in the time domain as in the existing random access channel configuration. Thus, when configuring the uplink wake-up signal through the first information, it is beneficial to reduce the number of bits used for configuring the uplink wake-up signal, thereby reducing the transmission power consumption of the uplink wake-up signal configuration.

[0188] Optionally, when reusing the existing random access channel configuration, the first information may still include the number of random access opportunities in the frequency domain, but the number of random access opportunities in the frequency domain may be 1, or in other words, there may only be one random access opportunity in the frequency domain.

[0189] It should be noted that, as can be seen from the above, the terminal device only needs to send an uplink wake-up signal once to wake up the network device. Therefore, it can be understood that only one uplink wake-up signal needs to be sent in the frequency domain. In other words, there is only one frequency domain position corresponding to the random access opportunity, or the number of random access opportunities in the frequency domain can be 1.

[0190] In the above implementation, when configuring the uplink wake-up signal through the first information, although it is still necessary to configure the number of random access opportunities in the frequency domain, only one random access opportunity needs to be configured in the frequency domain, instead of configuring multiple random access opportunities in the frequency domain as in the existing random access channel configuration. Thus, when configuring the uplink wake-up signal through the first information, it is beneficial to reduce the number of bits used for configuring the uplink wake-up signal, thereby reducing the transmission power consumption of the uplink wake-up signal configuration.

[0191] Regarding the first information, which does not include the spatial resource configuration included in the random access channel configuration, it should be noted that when the terminal device sends the uplink wake-up signal, it does not need to select an appropriate beam for transmission based on the measured SSB beam. It can send the uplink wake-up signal on beams in all directions, i.e., omnidirectional transmission of the uplink wake-up signal. Therefore, when configuring the uplink wake-up signal using the first information, it is not necessary to configure the transmission beam corresponding to the uplink wake-up signal; that is, the first information may not include the spatial resource configuration included in the random access channel configuration.

[0192] Regarding the first information excluding the number of random access preambles, it should be noted that, as mentioned above, the terminal device only needs to send one uplink wake-up signal to the network device to wake it up. Correspondingly, this one uplink wake-up signal corresponds to only one random access preamble, meaning the number of random access preambles is 1. It should be understood that since this single random access preamble is only used to wake up the network device and not for the terminal device to initiate random access, even if it conflicts with other terminal devices, it has no impact on the network device. Therefore, when configuring the uplink wake-up signal through the first information, it is not necessary to configure the number of random access preambles. It should be understood that not configuring the number of random access preambles means that the number of random access preambles is 1.

[0193] Regarding the format where the first information does not include a random access preamble, it should be noted that, as explained above, the terminal device only needs one random access preamble, which can correspond to any sequence format. Therefore, when configuring the uplink wake-up signal through the first information, the format of the random access preamble does not need to be configured. It should be understood that not configuring the format of the random access preamble means that the format of the random access preamble can be any sequence format. Optionally, the format of the random access preamble can be predefined by the protocol, for example, it can be the C2 format.

[0194] Regarding the first information excluding the cyclic shift value of the random access preamble, it should be noted that the cyclic shift value of the random access preamble, i.e., the cyclic shift value used by the uplink wake-up signal, can be a fixed value, for example, it can be predefined by the protocol. Therefore, when configuring the uplink wake-up signal through the first information, it is not necessary to configure the cyclic shift value of the random access preamble.

[0195] Regarding the first information excluding the root sequence index of the random access preamble, it should be noted that, as explained above, the terminal device only needs one random access preamble. A random access preamble is generated by a specific root sequence and its cyclic shift, meaning one random access preamble corresponds to one root sequence index. Therefore, only one root sequence index is needed for the random access preamble. Thus, when configuring the uplink wake-up signal using the first information, the root sequence index of the random access preamble does not need to be configured. Optionally, the root sequence index of the random access preamble can be predefined by the protocol.

[0196] In one optional implementation, the first information, while reusing the existing random access channel configuration, may not include the system information request configuration period. That is, the first information may at least include the frame structure ratio in the random access channel configuration, the position of the random access opportunity in the time domain, the subcarrier spacing, the frequency domain bandwidth, the position of the random access opportunity in the frequency domain, the constraint set configuration, the transmit power of the random access preamble, the power ramp step size, and the maximum number of transmissions of the random access preamble.

[0197] It should be noted that the system information request configuration period is a relatively unimportant configuration for the uplink wake-up signal. Therefore, when configuring the uplink wake-up signal through the first information, it is not necessary to configure the system information request configuration period. Optionally, the system information request configuration period can be configured in SIB1, or it can be configured in the random access response.

[0198] S402, the network device sends the first information to the terminal device. Correspondingly, the terminal device receives the first information.

[0199] In some feasible implementations, after determining the first information, the network device can send the first information to the terminal device. Correspondingly, the terminal device can receive the first information.

[0200] Optionally, the first information can be carried in a synchronization signal, such as an SSB. Alternatively, the network device can send a synchronization signal to the terminal device, where the synchronization signal can carry the first information. In possible scenarios, the first information can also be carried in other signals with synchronization functionality; this application embodiment is not limited in this regard.

[0201] S403, the terminal device sends an uplink wake-up signal to the network device based on the first information. Correspondingly, the network device receives the uplink wake-up signal.

[0202] In some feasible implementations, after receiving the first information, the terminal device can send an uplink wake-up signal to the network device based on the first information. Accordingly, the network device can receive the uplink wake-up signal and be woken up to communicate with the terminal device.

[0203] In the above implementation, the network device can configure the uplink wake-up signal for the terminal device by sending first information. Compared with the uplink wake-up signal configuration in the existing scheme that fully reuses the random access channel configuration, the first information can reduce unnecessary configuration when reusing the random access channel configuration. Thus, when configuring the uplink wake-up signal through the first information, fewer random access channel configurations can be reused, reducing the number of bits used for uplink wake-up signal configuration, and thereby reducing the transmission power consumption of uplink wake-up signal configuration.

[0204] Optionally, please continue to see Figure 4 , Figure 4 The communication method shown may further include steps S404 and S405. It should be understood that steps S404 and S405 may be performed after step S403.

[0205] S404, the network device sends a random access channel configuration to the terminal device. Correspondingly, the terminal device receives the random access channel configuration.

[0206] In some feasible implementations, after being woken up, the network device can send a random access channel configuration to the terminal device to configure the random access channel, or in other words, configure the resources of the random access channel.

[0207] Optionally, the network device can send the random access channel configuration to the terminal device through SIB1; that is, SIB1 can include the random access channel configuration. It should be noted that the random access channel configuration included in SIB1 here is consistent with the random access channel configuration in existing solutions. In other words, SIB1 contains complete random access channel configuration information, namely, frequency space-time resource configuration, preamble-related configuration, power domain resource configuration, and other resource configurations. For details, please refer to the relevant descriptions above, which will not be repeated here.

[0208] S405, terminal equipment and network equipment perform random access procedures.

[0209] In some feasible implementations, after obtaining the random access channel configuration, the terminal device can initiate random access to the network device according to the random access channel configuration, and then the terminal device and the network device can execute the random access process.

[0210] The specific details of the random access process performed by the terminal equipment and network equipment can be found in the previous descriptions, and will not be repeated here.

[0211] Figure 4 The illustrated embodiment describes how the first information, when reusing the existing random access channel configuration, can reduce unnecessary configuration and thus be used to configure the uplink wake-up signal. However, for random access, the first information is not used to configure the random access channel; instead, it decouples the configuration of the uplink wake-up signal from the random access channel configuration by using the random access configuration in the current communication standard (i.e., the aforementioned complete random access configuration). This solves the problem in the prior art where, because the uplink wake-up signal configuration completely reuses the random access channel configuration, the uplink wake-up signal is still bound to the random access function, resulting in the uplink wake-up signal occupying a large number of bits.

[0212] The following will combine Figure 5 The introduction states that when the first information can be used to configure the uplink wake-up signal and also to configure the random access channel, the first information can reduce unnecessary configuration when reusing the existing random access channel configuration. This can also reduce the number of bits used for configuring the uplink wake-up signal, thereby reducing the transmission power consumption of the uplink wake-up signal configuration.

[0213] Please see Figure 5 , Figure 5 This is a flowchart illustrating another communication method provided in an embodiment of this application. It should be understood that... Figure 5 The communication method shown can be applied to Figure 1 or Figure 2 The communication system shown is illustrated. Specifically, the communication method can be interactively executed by a network device and a terminal device. It should be noted that the method executed by the network device in this application can also be interactively executed by a chip, chip system, or processor within the network device; similarly, the method executed by the terminal device in this application can also be interactively executed by a chip, chip system, or processor within the terminal device, and this application does not impose specific limitations in this regard. Figure 5 As shown, the communication method may include the following steps:

[0214] S501, the network device determines the first information.

[0215] Specifically, this first information can be used to configure the uplink wake-up signal, or in other words, to configure the resources for the uplink wake-up signal. It should be noted that the first information can also be used to configure the random access channel, or in other words, to configure the resources for the random access channel. That is to say, the first information can configure both the uplink wake-up signal and the random access channel simultaneously.

[0216] The first information can reuse the random access channel configuration in the existing scheme, but compared with the existing random access channel configuration, the first information may not include the random access response reception window configuration, and / or the system information request configuration period.

[0217] In other words, the first information may at least include the frame structure configuration in the random access channel configuration, the position of the random access opportunity in the time domain, the subcarrier spacing, the frequency domain bandwidth, the position of the random access opportunity in the frequency domain, the number of repetitions of the random access opportunity in the frequency domain, the spatial resource configuration, the number of random access preambles, the format of the random access preamble, the cyclic shift number of the random access preamble, the root sequence index of the random access preamble, the constraint set configuration of the random access preamble, the transmit power of the random access preamble, the power ramp step size, and the maximum number of transmissions of the random access preamble. In possible scenarios, the first information may also include the period configured for the system information request or the receive window configuration for the random access response.

[0218] Here, for the case where the first information is used to configure the uplink wake-up signal, the reason why the first information does not include the receive window configuration of the random access response is related to... Figure 4 In the embodiment shown, the reason why the first information does not include the receiving window configuration of the random access response is similar, and the relevant content of step S401 above can be found, so it will not be repeated here.

[0219] Even if the first information does not include the receive window configuration for the random access response, or if the first information is also used to configure the random access channel, the receive window for the random access response can be determined based on the receive window of SIB1. Specifically, the detailed process for determining the receive window of the random access response based on the receive window of SIB1 can be found in the relevant content of step S401 above.

[0220] If the first information does not include the system information request configuration period, then the uplink wake-up signal and random access channel are relatively unimportant configurations. Therefore, when configuring both the uplink wake-up signal and random access channel simultaneously through the first information, the system information request configuration period does not need to be configured. Optionally, the terminal device can obtain the system information request configuration period by receiving SIB1 from the network device, or by receiving a random access response from the network device.

[0221] S502, the network device sends the first information to the terminal device. Correspondingly, the terminal device receives the first information.

[0222] In some feasible implementations, after determining the first information, the network device can send the first information to the terminal device. Correspondingly, the terminal device can receive the first information.

[0223] The process of the network device sending the first information can be found in the relevant content of step S402 above, and will not be repeated here.

[0224] S503, the terminal device sends an uplink wake-up signal to the network device based on the first information. Correspondingly, the network device receives the uplink wake-up signal.

[0225] In some feasible implementations, after receiving the first information, the terminal device can send an uplink wake-up signal to the network device based on the first information. Accordingly, the network device can receive the uplink wake-up signal and be woken up to communicate with the terminal device.

[0226] In the above implementation, the network device can configure the uplink wake-up signal for the terminal device by sending first information. Compared with the uplink wake-up signal configuration that fully reuses the random access channel configuration in the existing scheme, the first information can reduce unnecessary configurations when reusing the random access channel configuration, namely the period of the random access response receive window configuration and / or system information request configuration. Thus, when configuring the uplink wake-up signal through the first information, fewer random access channel configurations can be reused, reducing the number of bits used for uplink wake-up signal configuration, and thereby reducing the transmission power consumption of uplink wake-up signal configuration.

[0227] Optionally, please continue to see Figure 5 , Figure 5 The communication method shown may further include step S504. It should be understood that step S504 may be performed after step S503.

[0228] S504, terminal equipment and network equipment perform random access procedures.

[0229] In some feasible implementations, after obtaining the first information, the terminal device can initiate random access to the network device based on the first information, and then the terminal device and the network device can execute the random access process.

[0230] It should be noted that, in Figure 5 In the embodiment shown, since the first information can be used not only to configure the uplink wake-up signal but also to configure the random access channel, the terminal device can directly initiate random access to the network device after obtaining the first information, without needing to first obtain the random access channel configuration through the SIB1 sent by the network device before initiating random access.

[0231] It should also be noted that in actual implementation, network devices can still send SIB1 to terminal devices, and SIB1 can include the complete random access channel configuration in existing technologies. However, it should be understood that... Figure 5In the embodiment shown, the terminal device will not initiate random access based on the random access channel configuration included in SIB1, but can directly initiate random access based on the random access channel configuration included in the first information.

[0232] The above, combined with Figures 4 to 5 The communication method provided in the embodiments of this application is described in detail below. Figure 6 and Figure 7 The communication device provided in the embodiments of this application is described in detail. It should be understood that the description of the embodiments of the communication device corresponds to the description of the embodiments of the communication method; therefore, any parts not described in detail can be referred to the foregoing method embodiments.

[0254] In one possible implementation, the transceiver unit 602 is further configured to receive MIB messages. These MIB messages include the time window position for receiving SIB1, i.e., the receiving window of SIB1, or the time-domain information of SIB1.
