[0034] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0035] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. A person skilled in the art will appreciate that, with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0036] Please refer to FIG1 , which shows a schematic diagram of a network architecture 100 provided by an embodiment of the present application. The network architecture 100 may include: a terminal device 10 , an access network device 20 , and a core network element 30 .

[0037] The terminal device 10 may refer to a UE (User Equipment), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a wireless communication device, a user agent, or a user apparatus. In some embodiments, the terminal device 10 may also be a cellular phone, a cordless phone, a SIP (Session Initiation Protocol) phone, a WLL (Wireless Local Loop) station, a PDA (Personal Digital Assistant), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a 5GS (5th Generation System) or a terminal device in a future evolved PLMN (Public Land Mobile Network), etc., and the embodiments of the present application are not limited thereto. For ease of description, the above-mentioned devices are collectively referred to as terminal devices. The number of terminal devices 10 is generally multiple, and one or more terminal devices 10 may be distributed in a cell managed by each access network device 20. The terminal device may also be referred to as a terminal or UE for short, and those skilled in the art will understand its meaning.

[0038] Access network equipment 20 is a device deployed in an access network to provide wireless communication capabilities for terminal devices 10. Access network equipment 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different wireless access technologies, the names of devices that provide access network equipment functions may vary. For example, in 5G NR systems, they are referred to as gNodeBs or gNBs. As communication technologies evolve, the term "access network equipment" may change. For ease of description, in the embodiments of this application, the aforementioned devices that provide wireless communication capabilities for terminal devices 10 are collectively referred to as access network equipment. In some embodiments, access network equipment 20 enables communication between terminal devices 10 and core network elements 30. For example, in an LTE (Long Term Evolution) system, access network equipment 20 may be an Evolved Universal Terrestrial Radio Access Network (EUTRAN) or one or more eNodeBs within the EUTRAN. In a 5G NR system, access network equipment 20 may be a Radio Access Network (RAN) or one or more gNBs within the RAN. In the embodiment of the present application, unless otherwise specified, the "network device" refers to the access network device 20, such as a base station.

[0039] The core network element 30 is a network element deployed in the core network. The functions of the core network element 30 are mainly to provide user connection, user management, and service bearer, and to provide an interface to the external network as a bearer network. For example, the core network elements in the 5G NR system may include network elements such as the AMF (Access and Mobility Management Function) entity, the UPF (User Plane Function) entity, and the SMF (Session Management Function) entity.

[0040] Synaesthesia refers to the integration of communication and perception, enabling future communication systems to simultaneously perform both functions. While transmitting information over wireless channels, systems proactively learn and analyze channel characteristics to perceive the physical characteristics of the surrounding environment, thereby enhancing these two functions. For example, using base station signals to sense the surrounding environment allows communication links to be designed to avoid obstacles and improve communication performance.

[0041] Next-generation networks (such as B5G and 6G networks) are expected to be a fusion of mobile communication networks, perception networks, and computing power networks. In a narrow sense, a perception network refers to a system capable of target positioning (ranging, speed, and angle measurement), target imaging, target detection, target tracking, and target recognition. In a broad sense, a perception network refers to a system that understands the attributes and status of all services, networks, users, and terminals, as well as environmental objects. From the perspective of perception applications, perception can be classified into the following categories:

[0042] Outdoor, wide-area or local-area applications: including smart cities (e.g., weather monitoring), smart transportation / high-speed rail (e.g., high-precision map construction, road supervision, intrusion detection), and low-altitude applications (e.g., drone monitoring and obstacle avoidance, flight intrusion detection, flight path management).

[0043] Indoor or local applications: including smart home and health management (such as respiratory monitoring, intrusion detection, gesture / posture recognition, motion monitoring, mobile trajectory tracking, etc.), smart factories (such as intrusion detection, material detection, object defect detection, etc.), etc.

[0044] The above is just an example, providing some classifications of perception applications. The application areas of perception are not limited to the above examples.

[0045] Wireless communication and sensing are two key applications of modern radio frequency technology. Sensing uses radio waves to detect parameters of the physical environment to enable environmental perception, such as target location, motion recognition, and imaging. Traditionally, sensing and wireless communication exist independently, and this separate design wastes wireless spectrum and hardware resources. Entering the B5G (Beyond 5G) and 6G eras, the communication spectrum is shifting towards millimeter-wave, terahertz, and visible light communications. The spectrum for wireless communication will overlap with the spectrum for traditional sensing. Integrated communication and sensing technology merges wireless communication and sensing functions, leveraging wireless resources for sensing. It can leverage widely deployed cellular networks to achieve sensing services over larger areas. It can leverage base stations and multiple terminals for joint sensing, achieving higher sensing accuracy. It can also reuse wireless communication hardware modules for sensing, reducing costs. In short, integrated communication and sensing technology empowers future wireless communication systems with sensing capabilities, laying the foundation for the development of smart transportation, smart cities, smart factories, drones, and other services.

[0046] "Perception," as used in the embodiments of this application, refers to the process of directly or indirectly obtaining perceptual information about a target or environment based on at least one perceptual signal, such as sound waves, electromagnetic waves, or light waves (including but not limited to lasers). For example, perceptual information about a target or environment may be obtained by sending and receiving perceptual signals and measuring or otherwise processing the perceptual signals, thereby enabling services such as positioning, ranging, speed measurement, angle measurement, target imaging, target detection, target tracking, and target recognition.

[0047] In addition, the word "perception" mentioned in the embodiments of the present application can also be replaced by any other word that can express perception-related meanings, such as positioning, ranging, speed measurement, angle measurement, target imaging, target detection, target tracking and target recognition.

[0048] The nodes involved in perception are as follows:

[0049] Perception sending node: the sending node of the perception signal.

[0050] Perception receiving node: a receiving node that perceives signals.

[0051] Perception nodes: Perception sending nodes and perception receiving nodes are collectively referred to as perception nodes, that is, nodes that perform perception.

[0052] Perception Management Node: A node that manages and controls perception tasks. The Perception Management Node assigns perception tasks to the Perception Nodes, which then perform perception and provide feedback to the Perception Management Node after performing the perception task.

[0053] Regarding perception, it can be divided into 8 modes as shown in Figure 2.

[0054] Mode 1, base station self-transmitting and self-receiving sensing: The base station transmits a sensing signal and receives an echo signal. In Mode 1, the sensing transmitting node and the sensing receiving node are the same base station. That is, the base station transmits a sensing signal to the sensing target. After the sensing signal is reflected by the sensing target, the same base station receives an echo signal (i.e., the sensing signal after being reflected by the sensing target).

[0055] Mode 2, terminal-based self-transmission and self-reception: The terminal sends a sensing signal and receives an echo signal. In Mode 2, the sensing sending node and the sensing receiving node are the same terminal. That is, the terminal sends a sensing signal to the sensing target, which is then reflected by the sensing target and then received by the same terminal as the echo signal.

[0056] Mode 3, base station cooperative sensing: One base station (base station A in the figure) transmits a sensing signal, and another base station (base station B in the figure) receives the echo signal. In Mode 3, the sensing sending node and the sensing receiving node are different base stations. That is, one base station transmits a sensing signal to the sensing target, which is then reflected by the sensing target and then received as an echo signal by the other base station.

[0057] Mode 4, terminal collaborative sensing: One terminal (such as terminal A in the figure) transmits a sensing signal, and another terminal (such as terminal B in the figure) receives the echo signal. In Mode 4, the sensing sending node and the sensing receiving node are different terminals. That is, one terminal transmits a sensing signal to the sensing target, which is then reflected by the sensing target and then received as an echo signal by the other terminal.

[0058] Mode 5, base station-terminal collaborative sensing: The base station transmits a sensing signal, and the terminal receives an echo signal. In Mode 5, the base station is the sensing transmitting node, and the terminal is the sensing receiving node. Specifically, the base station transmits a sensing signal to the sensing target, which is then reflected by the sensing target and then received as an echo signal by the terminal.

[0059] Mode 6, terminal-base station collaborative sensing: The terminal transmits a sensing signal, and the base station receives an echo signal. In Mode 6, the sensing transmitting node is the terminal, and the sensing receiving node is the base station. Specifically, the terminal transmits a sensing signal to the sensing target, which is then reflected by the sensing target and then received as an echo signal by the base station.

[0060] In Mode 7, the sensing target is the sensing signal sending node. In Mode 7, the sensing sending node is the terminal, and the sensing receiving node is the base station. Because the sensing target (terminal) is the sensing sending node, the sensing signal is sent from the sensing sending node (terminal) to the sensing receiving node (base station) without reflection. The base station can directly receive and interpret the sensing result.

[0061] In Mode 8, the sensing target is the sensing signal receiving node. In Mode 8, the sensing sending node is the base station, and the sensing receiving node is the terminal. Since the sensing target (terminal) is the sensing receiving node, after receiving the sensing signal, the terminal needs to feed back the sensing result to the base station so that the base station can obtain the sensing result.

[0062] It should be noted that, for the sake of convenience, in the embodiment of the present application, the echo signal in Figure 2 is also called a perception signal.

[0063] The nodes that transmit and receive sensing signals are collectively referred to as sensing nodes. In the eight sensing modes described above, there is only one or a pair of sensing nodes. However, in wireless communication systems, there are a large number of terminal devices (such as mobile phones and IoT devices). When multiple sensing nodes (i.e., base stations, mobile phones, IoT devices, etc.) are present around a perceived object, the joint participation of multiple sensing nodes in sensing can improve perception accuracy, meet more complex sensing service requirements, and provide richer sensing services. As shown in Figure 3, when there are multiple sensing nodes in the system (such as sensing nodes 1, 2, and 3 in Figure 3), a sensing control node 31 may be present to control and manage the entire sensing service to improve efficiency. This sensing control node 31 can be a base station, a terminal device, or a core network element.

[0064] Please refer to FIG4 , which shows a flow chart of a wireless communication method provided by an embodiment of the present application. The method includes the following step 410 .

[0065] In step 410 , the network device sends first information, where the first information is used to determine a first resource, where the first resource is used to transmit a perception signal and is not used to transmit a communication signal.

[0066] Correspondingly, the terminal device receives the first information.

[0067] First resources refer to time-frequency resources that are not used to transmit communication signals in a communication system. Time-frequency resources are determined based on the time domain resource location and the frequency domain resource location. The time domain resource location refers to the resource location allocated in time, and the frequency domain resource location refers to the resource location allocated in frequency. The granularity for the division of time domain resources can be frames, subframes, time slots, subslots, symbols, symbol groups, etc. The granularity for the division of frequency domain resources can be RBs (Resource Blocks), RB groups, subcarriers, etc.

[0068] In some embodiments, during the transmission of a communication signal, if unavailable resources are encountered, a rate matching process may be performed before resource mapping, which is used to adjust the data volume (number of bits) of the resource mapping. Wherein, resource mapping refers to the process of allocating a communication signal to available time-frequency resources, and the data volume of resource mapping refers to the number of bits contained in the communication signal for which resource mapping is performed. Exemplarily, during the transmission of a communication signal, if unavailable resources (such as the first resource described above) are encountered, it can be considered that the time-frequency resources used to transmit the communication signal are relatively few, and therefore the number of bits of the communication signal for which resource mapping is performed is reduced. When no unavailable resources are encountered, it can be considered that the time-frequency resources used to transmit the communication signal are relatively many, and therefore the number of bits of the communication signal for which resource mapping is performed is increased. The rate matching process can ensure that the amount of data transmitted is within the limits of the available time-frequency resources, and maximizes the use of the available time-frequency resources. By reasonably adjusting the data volume of resource mapping, the transmission performance of the communication signal can be improved, and the reliability and efficiency of the transmission can be ensured.

[0069] A communication signal is a signal used to transmit information. The communication signal may include data information and control information, as well as reference signals for channel measurement. It is used to transmit specific service data and control the communication process in the communication system. Data information may be in the form of a TB (Transport Block), a PDU (Protocol Data Unit), etc. Control information may be in the form of UCI (Uplink Control Information), DCI (Downlink Control Information), configuration information, grant information, etc. Control information may also be referred to as signaling information. Generally speaking, control information has fewer bits than data information. Reference signals may be in the form of an SRS (Sounding Reference Signal), a CSI-RS (Channel State Information Reference Signal), etc.

[0070] In some embodiments, the first resource is used to transmit signals other than communication signals. In some embodiments, the other signals include perception signals, and the first resource is used to transmit perception signals. A perception signal refers to a signal used to obtain environmental information, and refers to a signal used to monitor, perceive or measure environmental information. It is mainly used to perceive and measure various information in the environment, such as target positioning (ranging, speed measurement, angle measurement), target imaging, target detection, target tracking and target identification, etc. The perception signal can be a perception signal sent or received by a terminal device, or it can be perception information sent or received by a network device (a network device to which the terminal device is connected), or it can be a perception signal sent or received by other network devices or other terminal devices.

[0071] In some embodiments, the first network device sends a first message to the first terminal device, and accordingly, the first terminal device receives the first message and determines a first resource based on the first message. In an embodiment of the present application, there is no limitation on the device that uses the first resource to transmit other signals (such as perception signals). For example, the first terminal device can transmit other signals (such as perception signals) through the first resource, or the first network device can transmit other signals (such as perception signals) through the first resource, or other terminal devices other than the first terminal device can transmit other signals (such as perception signals) through the first resource, or other network devices other than the first network device can transmit other signals (such as perception signals) through the first resource, and this application does not limit this.

[0072] In some embodiments, taking a perception signal as an example, after a first terminal device receives first information sent by a first network device and determines a first resource based on the first information, it learns the first resource available for transmitting the perception signal. When the first terminal device needs to send a perception signal, it can use the first resource to send the perception signal. For example, the first terminal device uses the first resource to send the perception signal to the first network device or another device.

[0073] In some embodiments, taking the perception signal as an example, after the first terminal device receives the first information sent by the first network device and determines the first resource based on the first information, it learns the first resource that can be used to transmit the perception signal. When the first network device, or other terminal devices other than the first terminal device, or other network devices other than the first network device have a need to send a perception signal, the first resource can be used to send the perception signal. For example, the first resource is used to send the perception signal to the first terminal device or other devices. If the first terminal device is the receiving end of the perception signal, the first terminal device can detect the above-mentioned first resource for transmitting the perception signal to obtain the perception signal sent by the first network device.

[0074] In some embodiments, the first information includes frequency domain information, wherein the frequency domain information is used to determine the frequency domain position of the first resource. The frequency domain position refers to the position or frequency range occupied by the first resource in the frequency domain.

[0075] In some embodiments, the frequency domain information includes first indication information, and the first indication information is used to determine a first frequency domain resource unit in the first frequency band, where the first frequency domain resource unit is a frequency domain resource unit where the first resource is located.

[0076] In some embodiments, the first frequency band is a carrier or a BWP (bandwidth part) used to carry signals. A carrier is a basic unit used to transmit information in wireless communications, while a BWP is a specific spectrum resource that can be used to transmit signals.

[0077] The first frequency band may include one or more frequency domain resource units. Among the one or more frequency domain resource units, the frequency domain resource unit where the first resource is located is referred to as a first frequency domain resource unit. Among the one or more frequency domain resource units, there may be at least one first frequency domain resource unit, and the first indication information is used to indicate the at least one first frequency domain resource unit.

[0078] A frequency domain resource unit is a resource division granularity in the frequency domain. A frequency domain resource unit can be any of the following: 1 RB, multiple consecutive RBs (such as called an RB group), 1 subcarrier, multiple consecutive subcarriers (such as called a subcarrier group), and this application does not limit this.

[0079] In some embodiments, the first frequency band includes N frequency domain resource units, the first indication information includes N bits, each of the N bits is used to indicate whether a frequency domain resource unit among the N frequency domain resource units is the first frequency domain resource unit, and N is a positive integer.

[0080] The first frequency band includes N frequency domain resource units, the first indication information includes N bits, and each of the N bits is used to indicate whether a frequency domain resource unit among the N frequency domain resource units is a first frequency domain resource unit.

[0081] Exemplarily, N is equal to 10, indicating that the first frequency band includes 10 frequency domain resource units, and the first indication information includes 10 bits, each of the 10 bits is used to indicate whether one of the 10 frequency domain resource units is the first frequency domain resource unit.

[0082] Exemplarily, when the frequency domain resource unit is 1 RB, the first frequency band includes 10 RBs, and the first indication information includes 10 bits, where each bit is used to indicate whether 1 RB among the 10 RBs is the first RB, and the first RB refers to the RB where the first resource is located.

[0083] Exemplarily, when the frequency domain resource unit is an RB group, the RB group refers to a set consisting of at least two consecutive RBs. The first frequency band includes 10 RB groups, and the first indication information includes 10 bits, each of which is used to indicate whether one of the 10 RB groups is a first RB group, where the first RB group is the RB group where the first resource is located.

[0084] Exemplarily, when the frequency domain resource unit is 1 subcarrier, the first frequency band includes 10 subcarriers, and the first indication information includes 10 bits, where each bit is used to indicate whether 1 subcarrier among the 10 subcarriers is the first subcarrier, and the first subcarrier is the subcarrier where the first resource is located.

[0085] Exemplarily, when the frequency domain resource unit is a subcarrier group, the subcarrier group refers to a set consisting of at least two consecutive subcarriers. The first frequency band includes 10 subcarrier groups, and the first indication information includes 10 bits, each of which is used to indicate whether one subcarrier group among the 10 subcarrier groups is a first subcarrier group, where the first subcarrier group is the subcarrier group where the first resource is located.

[0086] The above method, when the frequency domain resource unit is RB, can obtain RB resources that cannot be used to transmit communication signals through the above method; when the frequency domain resource unit is subcarrier, can obtain subcarrier resources that cannot be used to transmit communication signals through the above method. On the one hand, the first resource is not used to transmit communication signals, which can ensure the quality and performance of communication signals and other signals in the system. On the other hand, by refining the frequency domain position indication of the unavailable resources to the subcarrier, more accurate unavailable resources can be obtained. When one RB contains multiple subcarriers, by determining the subcarriers included in the first resource, and then using the other subcarriers that are not the first resource to transmit communication signals, the resource utilization rate of communication signal transmission is improved. For example, when an RB contains 10 subcarriers, 5 of which are first resources, the other 5 subcarriers of the RB can still be used to transmit communication signals, thereby improving the resource utilization rate of communication signal transmission.

[0087] In some embodiments, the first indication information includes N bits, and each of the N bits corresponds to two values, namely a first numerical value and a second numerical value, and the first numerical value and the second numerical value are different. Exemplarily, the first numerical value can be 0 and the second numerical value is 1. When the numerical value of the bit corresponding to the frequency domain resource unit is 1, the frequency domain resource unit is the first frequency domain resource unit, and when the numerical value of the bit corresponding to the frequency domain resource unit is 0, the frequency domain resource unit is not the first frequency domain resource unit. It can also be that when the numerical value of the bit corresponding to the frequency domain resource unit is 0, the frequency domain resource unit is the first frequency domain resource unit, and when the numerical value of the bit corresponding to the frequency domain resource unit is 1, the frequency domain resource unit is not the first frequency domain resource unit. This application does not limit this.

[0088] In some embodiments, if the frequency domain resource unit is an RB, N is determined according to the number of RBs included in the first frequency band and the number of RBs included in each frequency domain resource unit, and each frequency domain resource unit includes one RB or multiple consecutive RBs.

[0089] Exemplarily, when each frequency domain resource unit is 1 RB, as shown in sub-figure (a) of FIG5 , the first frequency band includes 10 RBs, and each frequency domain resource unit includes 1 RB, where RB0 is frequency domain resource unit 0, RB1 is frequency domain resource unit 1, ..., RB9 is frequency domain resource unit 9. Therefore, N is 10, that is, the first indication information includes 10 bits. Exemplarily, the first indication information is "0110000100" and bit 1 represents that the frequency domain resource unit is the first resource, so frequency domain resource unit 1 (RB1), frequency domain resource unit 2 (RB2), and frequency domain resource unit 7 (RB7) are the first frequency domain resource units (filled with oblique lines).

[0090] Exemplarily, when each frequency domain resource unit is an RB group, that is, a plurality of consecutive RBs, as shown in sub-figure (b) of Figure 5, the first frequency band includes 5 RB groups, each RB group includes 2 RBs, wherein RB0 and RB1 are frequency domain resource unit 0 (RB group 0), RB2 and RB3 are frequency domain resource unit 1 (RB group 1), ..., RB8 and RB9 are frequency domain resource unit 4 (RB group 4). Therefore, N is 5, that is, the first indication information includes 5 bits. Exemplarily, the first indication information is "10010" and bit 1 represents that the frequency domain resource unit (RB group) is the first resource, so frequency domain resource unit 0 (RB group 0, including RB0 and RB1) and frequency domain resource unit 3 (RB group 3, including RB6 and RB7) are the first frequency domain resource unit (the area filled with diagonal lines).

[0091] Exemplarily, if the frequency domain resource unit is 1 subcarrier, assuming that the first frequency band includes 10 subcarriers, each frequency domain resource unit includes 1 subcarrier, where subcarrier 0 is frequency domain resource unit 0, subcarrier 1 is frequency domain resource unit 1, ..., subcarrier 9 is frequency domain resource unit 9. Therefore, N is 10, that is, the first indication information includes 10 bits. Exemplarily, the first indication information is "0110000100" and bit 1 represents that the frequency domain resource unit is the first resource, so frequency domain resource unit 1 (subcarrier 1), frequency domain resource unit 2 (subcarrier 2) and frequency domain resource unit 7 (subcarrier 7) are the first frequency domain resource unit.

[0092] Exemplarily, if the frequency domain resource unit is a subcarrier group, that is, a plurality of consecutive subcarriers, it is assumed that the first frequency band contains 5 subcarrier groups, each subcarrier group contains 2 subcarriers, wherein subcarrier 0 and subcarrier 1 are frequency domain resource unit 0 (subcarrier group 0), subcarrier 2 and subcarrier 3 are frequency domain resource unit 1 (subcarrier group 1), ..., subcarrier 8 and subcarrier 9 are frequency domain resource unit 4 (subcarrier group 4). Therefore, N is 5, that is, the first indication information contains 5 bits. Exemplarily, the first indication information is "10010" and bit 1 represents that the frequency domain resource unit (subcarrier group) is the first resource, so frequency domain resource unit 0 (subcarrier group 0, including subcarrier 0 and subcarrier 1) and frequency domain resource unit 3 (subcarrier group 3, including subcarrier 6 and subcarrier 7) are the first frequency domain resource unit.

[0093] The above method, for each frequency domain resource, namely, one RB, one RB group, one subcarrier, or one subcarrier group, can determine, based on the first indication information, whether the one RB, one RB group, one subcarrier, or one subcarrier group is a first frequency domain resource unit. This approach can accurately obtain the first frequency domain resource unit. Furthermore, the first frequency domain resource unit is not used to transmit communication signals, reducing communication interference between communication signals and other signals, and improving the performance and reliability of the communication system.

[0094] In some embodiments, the first indication information is used to determine a starting frequency domain position and / or quantity of the first frequency domain resource unit.

[0095] The starting frequency domain position refers to the frequency domain position occupied by the first first frequency domain resource unit among one or more first frequency domain resource units in the frequency domain. The first first frequency domain resource unit refers to the frequency domain resource unit corresponding to the lowest frequency or the highest frequency among the frequency domain resource units.

[0096] Exemplarily, when the frequency domain resource unit is 1 RB, as shown in subfigure (c) in Figure 5 , the first frequency band includes 10 RBs, and each frequency domain resource unit includes 1 RB, where RB0 is frequency domain resource unit 0, RB1 is frequency domain resource unit 1, ..., RB9 is frequency domain resource unit 9. The first indication information may indicate that the starting frequency domain position is frequency domain resource unit 0 (RB0), and the number is 3, then RB0, RB1, and RB2 are the first frequency domain resource unit (the area filled with oblique lines).

[0097] Exemplarily, when each frequency domain resource unit is an RB group, that is, a plurality of consecutive RBs, assuming that the first frequency band includes 5 RB groups, each RB group includes 2 RBs, where RB0 and RB1 are frequency domain resource unit 0 (RB group 0), RB2 and RB3 are frequency domain resource unit 1 (RB group 1), ..., RB8 and RB9 are frequency domain resource unit 4 (RB group 4). The first indication information may indicate that the starting frequency domain position is frequency domain resource unit 0 and the number is 2, so frequency domain resource unit 0 (RB group 0, including RB0 and RB1) and frequency domain resource unit 1 (RB group 1, including RB2 and RB3) are the first frequency domain resource unit.

[0098] Exemplarily, when the frequency domain resource unit is 1 subcarrier, assuming that the first frequency band includes 10 subcarriers, each frequency domain resource unit includes 1 subcarrier, where subcarrier 0 is frequency domain resource unit 0, subcarrier 1 is frequency domain resource unit 1, ..., and subcarrier 9 is frequency domain resource unit 9. The first indication information may indicate that the starting frequency domain position is frequency domain resource unit 0 (subcarrier 0) and the number is 3, then subcarrier 0, subcarrier 1, and subcarrier 2 are the first frequency domain resource unit.

[0099] Exemplarily, when each frequency domain resource unit is a subcarrier group, that is, a plurality of consecutive subcarriers, it is assumed that the first frequency band contains 5 subcarrier groups, each subcarrier group contains 2 subcarriers, wherein subcarrier 0 and subcarrier 1 are frequency domain resource unit 0 (subcarrier group 0), subcarrier 2 and subcarrier 3 are frequency domain resource unit 1 (subcarrier group 1), ..., subcarrier 8 and subcarrier 9 are frequency domain resource unit 4 (subcarrier group 4). The first indication information may indicate that the starting frequency domain position is frequency domain resource unit 0 and the number is 2, so frequency domain resource unit 0 (subcarrier group 0, including subcarrier 0 and subcarrier 1) and frequency domain resource unit 1 (subcarrier group 1, including subcarrier 2 and subcarrier 3) are the first frequency domain resource unit.

[0100] The above method can determine the first frequency domain resource unit based on the starting frequency domain position and / or number of the first frequency domain resource unit, and the first frequency domain resource unit is continuous. In this way, when there are many frequency domain resource units in the first frequency band, fewer bits can be used to transmit the first indication information, which can save channel resources and bandwidth.

[0101] In some embodiments, the first indication information includes spacing information, where the spacing information is used to indicate the number of frequency domain resource units that are spaced apart between two adjacent first frequency domain resource units in the plurality of first frequency domain resource units. For example, when the spacing information is 1, it indicates that there is one frequency domain resource unit spaced apart between two adjacent first frequency domain resource units in the plurality of first frequency domain resource units.

[0102] In some embodiments, the first frequency domain resource unit is determined based on the starting frequency domain position, quantity, and spacing information of the first frequency domain resource unit. Exemplarily, when the frequency domain resource unit is 1 RB, the first frequency band includes 10 RBs, each frequency domain resource unit includes 1 RB, where RB0 is frequency domain resource unit 0, RB1 is frequency domain resource unit 1, ..., RB9 is frequency domain resource unit 9. The first indication information may indicate that the starting frequency domain position is frequency domain resource unit 0 (RB0), the quantity may be 3, and the spacing information may be 1, then RB0, RB2, and RB4 are the first frequency domain resource units.

[0103] The above method can determine the first frequency domain resource unit based on the starting frequency domain position, number and interval information of the first frequency domain resource unit, and the multiple first frequency domain resource units can be discontinuous frequency domain resource units, thereby improving the flexibility and diversity of the first frequency domain resource unit indication.

[0104] In some embodiments, the first indication information includes at least one of a first period, a first offset value and a first quantity; the first period is used to indicate the number of frequency domain resource units contained in each frequency domain resource unit period in the first frequency band; the first offset value is used to indicate the position of the first first frequency domain resource unit in each frequency domain resource unit period; the first quantity is used to indicate the number of first frequency domain resource units in each frequency domain resource unit period.

[0105] A frequency domain resource period is a set of continuous frequency domain resource units, represented as a continuous frequency range in the frequency domain. A first frequency band includes at least one frequency domain resource period. Each frequency domain resource period includes at least one frequency domain resource unit. The first offset value is the frequency domain position of the first first frequency domain resource unit in each frequency domain resource period.

[0106] For example, as shown in sub-figure (d) of FIG5 , when the frequency-domain resource unit is one RB, the first period in the first indication information may be 10, i.e., the number of RBs contained in each frequency-domain resource unit period is 10. Assume that in each frequency-domain resource unit period, RB0 is frequency-domain resource unit 0, RB1 is frequency-domain resource unit 1, ..., RB9 is frequency-domain resource unit 9. In the first indication information, the first offset value may be 0, and the first number may be 2, i.e., the first first frequency-domain resource unit in each frequency-domain resource unit period is frequency-domain resource unit 0 (RB0), and the number of first frequency-domain resource units is 2. Therefore, in each frequency-domain resource unit period, frequency-domain resource unit 0 (RB0) and frequency-domain resource unit 1 (RB1) are first frequency-domain resource units. As shown in sub-figure (d) of FIG5 , in the first frequency-domain resource unit period, frequency-domain resource units 51 and 52 are first frequency-domain resource units, and in the last frequency-domain resource unit period, frequency-domain resource units 53 and 54 are first frequency-domain resource units.

[0107] Exemplarily, when each frequency domain resource unit is an RB group, that is, a plurality of consecutive RBs, in the first indication information, the first period may be 5, that is, the number of RB groups contained in each frequency domain resource unit period is 5, assuming that in each frequency domain resource unit period, RB0 and RB1 are frequency domain resource unit 0, RB2 and RB3 are frequency domain resource unit 1, ..., RB8 and RB9 are frequency domain resource unit 4. In the first indication information, the first offset value may be 1, and the first number may be 2, that is, the first first frequency domain resource unit in each frequency domain resource unit period is frequency domain resource unit 1 (including RB2 and RB3), and the number of first frequency domain resource units is 2. Therefore, in each frequency domain resource unit period, frequency domain resource unit 1 (including RB2 and RB3) and frequency domain resource unit 2 (including RB4 and RB5) are first frequency domain resource units.

[0108] Exemplarily, when the frequency domain resource unit is 1 subcarrier, in the first indication information, the first period may be 10, that is, the number of subcarriers included in each frequency domain resource unit period is 10, assuming that in each frequency domain resource unit period, subcarrier 0 is frequency domain resource unit 0, subcarrier 1 is frequency domain resource unit 1, ..., subcarrier 9 is frequency domain resource unit 9. In the first indication information, the first offset value may be 1, and the first number may be 2, that is, the first first frequency domain resource unit in each frequency domain resource unit period is frequency domain resource unit 1 (subcarrier 1), and the number of first frequency domain resource units is 2. Therefore, in each frequency domain resource unit period, frequency domain resource unit 1 (subcarrier 1) and frequency domain resource unit 2 (subcarrier 2) are first frequency domain resource units.

[0109] Exemplarily, when each frequency domain resource unit is a subcarrier group, that is, a plurality of consecutive subcarriers, in the first indication information, the first period may be 5, that is, the number of subcarrier groups contained in each frequency domain resource unit period is 5, assuming that in each frequency domain resource unit period, subcarrier 0 and subcarrier 1 are frequency domain resource unit 0, subcarrier 2 and subcarrier 3 are frequency domain resource unit 1, ..., subcarrier 8 and subcarrier 9 are frequency domain resource unit 4. In the first indication information, the first offset value may be 2, and the first number may be 2, that is, the first first frequency domain resource unit in each frequency domain resource unit period is frequency domain resource unit 2 (including subcarrier 4 and subcarrier 5), and the number of first frequency domain resource units is 2. Therefore, in each frequency domain resource unit period, frequency domain resource unit 2 (including subcarrier 4 and subcarrier 5) and frequency domain resource unit 3 (including subcarrier 6 and subcarrier 7) are first frequency domain resource units.

[0110] The above method determines the first frequency domain resource unit according to the first period, the first offset value and the first quantity. This method can periodically determine the distribution and quantity of the first frequency domain resource unit, thereby improving the flexibility of indicating the first frequency domain resource unit.

[0111] In some embodiments, the frequency domain information only includes the first indication information, and when the frequency domain resource is one or multiple consecutive RBs, when the one or multiple consecutive RBs are the first frequency domain resources, all subcarriers included in the one or multiple consecutive RBs are the first resources.

[0112] In some embodiments, the frequency domain information includes second indication information, and the second indication information is used to determine the first subcarrier in the first frequency domain resource unit, the first frequency domain resource unit is the frequency domain resource unit where the first resource is located, and the first subcarrier is the subcarrier where the first resource is located.

[0113] Each of the one or more first frequency-domain resource units may be one RB or an RB group (a plurality of consecutive RBs). The one RB or RB group includes at least one subcarrier.

[0114] In some embodiments, when the frequency domain information only includes the second indication information, the first frequency domain resource unit can be predetermined or indicated, for example, by a protocol agreement or by a network device indicating to the terminal device. The protocol agrees on the first frequency domain resource unit in the first frequency band, such as agreeing on the first two frequency domain resource units in the first frequency band as the first frequency domain resource unit, or agreeing on the last two frequency domain resource units in the first frequency band as the first frequency domain resource unit, which is not limited in this application.

[0115] The above method can determine the first subcarrier in the first frequency domain resource unit according to the second indication information. The first subcarrier is the first resource that cannot be used to transmit communication signals. The other subcarriers contained in the first frequency domain resource unit except the first subcarrier can still be used to transmit communication signals, which is conducive to improving resource utilization.

[0116] In some embodiments, the first frequency domain resource unit includes M subcarriers, and the second indication information includes M bits, each of the M bits corresponds to two values, namely a first value and a second value, and the first value and the second value are different. Exemplarily, the first value can be 0 and the second value is 1. When the value of the bit corresponding to the subcarrier is 1, the subcarrier is the first subcarrier, and when the value of the bit corresponding to the subcarrier is 0, the subcarrier is not the first subcarrier. Alternatively, when the value of the bit corresponding to the subcarrier is 0, the subcarrier is the first frequency domain resource unit, and when the value of the bit corresponding to the subcarrier is 1, the subcarrier is not the first subcarrier. This application does not limit this.

[0117] In some embodiments, M is equal to the number of subcarriers included in the first frequency domain resource unit. When there is only one first frequency domain resource unit or when there are multiple first frequency domain resource units and the positions of the first subcarriers in the multiple first frequency domain resource units are the same, M is equal to the number of subcarriers included in the first frequency domain resource unit. Exemplarily, as shown in subfigure (a) in Figure 6, it is assumed that the first frequency band contains 10 frequency domain resource units, each frequency domain resource unit contains 1 RB, and it is assumed that the first frequency domain resource units are RB1, RB2 and RB7, and the number of subcarriers included in each first frequency domain resource unit is 12. Therefore, the second indication information contains 12 bits, which is "100100011000", that is, subcarrier 0, subcarrier 3, subcarrier 7 and subcarrier 8 of RB1, RB2 and RB7 are first subcarriers.

[0118] In some embodiments, M is equal to the product of the number of subcarriers included in the first frequency-domain resource unit and the number of the first frequency-domain resource units.

[0119] When there is one first frequency domain resource unit, M is equal to the number of subcarriers included in the first frequency domain resource unit.

[0120] When there are multiple first frequency domain resource units, and the positions of the first subcarriers in the multiple first frequency domain resource units are at least two different, exemplarily, as shown in sub-figure (b) in FIG6 , assuming that the first frequency band includes 10 frequency domain resource units, each frequency domain resource unit includes 1 RB, assuming that the first frequency domain resource units are RB1, RB2 and RB7, that is, the number of first frequency domain resource units is 3, and the number of subcarriers included in each first frequency domain resource unit is 12. Therefore, the second indication information contains 36 bits, which can be "100100011000,000000000011,000100000000", so subcarrier 0, subcarrier 3, subcarrier 7 and subcarrier 8 of RB1, subcarrier 10 and subcarrier 11 of RB2, and subcarrier 3 of RB7 are the first subcarrier.

[0121] When there are multiple first frequency domain resource units and the positions of the first subcarriers in the multiple first frequency domain resource units are the same, the second indication information can also be indicated in the above manner, that is, M is equal to the product of the number of subcarriers contained in the first frequency domain resource unit and the number of first frequency domain resource units. This application does not limit this.

[0122] In the above method, when the positions of the first subcarriers in multiple first frequency domain resource units are the same, the second indication information includes fewer bits, which is beneficial to reducing the overhead of transmitting the second indication information; when the positions of the first subcarriers in multiple first frequency domain resource units are different, the second indication information includes more bits, which improves the flexibility and diversity of the first subcarrier indication.

[0123] In some embodiments, the frequency domain information includes first indication information and second indication information, the first indication information is used to determine the first frequency domain resource unit in the first frequency band, and the second indication information is used to determine the first subcarrier in the first frequency domain resource unit. As shown in Figure 7, the first frequency band contains 10 frequency domain resource units, each frequency domain resource unit contains 1 RB, and the position of the first subcarrier in each frequency domain resource unit is the same. Exemplarily, the first information is "0110000100", so the first frequency domain resource units are RB1, RB2 and RB7, and the second indication information is "100100011000", so subcarrier 0, subcarrier 3, subcarrier 7 and subcarrier 8 of RB1, RB2 and RB7 are the first subcarriers. The above method can determine the first subcarrier of the first frequency band based on the first indication information and the second indication information, so that the indication of the first resource is more flexible and diverse.

[0124] In some embodiments, the first information includes: time domain information, and the time domain information is used to determine the time domain position of the first resource.

[0125] The time domain position refers to the specific position or range of the first resource in time.

[0126] In some embodiments, the time domain information includes third indication information, and the third indication information is used to determine a first time domain unit in each time domain period, where the first time domain unit is a time domain unit where the first resource is located.

[0127] A time domain period refers to a set of continuous time domain units, represented as a continuous time range in the time domain. Each time domain period includes one or more time domain units. Among the one or more time domain units, there may be at least one first time domain unit, and the third indication information is used to indicate the at least one first time domain unit. In addition, the time domain period can be predetermined or indicated, for example, by a protocol agreement or by a network device indicating to a terminal device, and this application does not limit this.

[0128] A time domain unit refers to a resource division granularity in the time domain. A time domain unit can be 1 time slot, multiple consecutive time slots (such as a time slot group), 1 symbol, or multiple consecutive symbols (such as a symbol group), which is not limited in this application.

[0129] In some embodiments, each time domain period includes P time domain units, the third indication information includes P bits, each of the P bits is used to indicate whether a time domain unit in the P time domain units is a first time domain unit, and P is a positive integer.

[0130] Exemplarily, P is equal to 14, indicating that each time domain period includes 14 time domain units, and the third indication information includes 14 bits, each of the 14 bits is used to indicate whether a time domain unit among the 14 time domain units is the first time domain unit.

[0131] Exemplarily, when the time domain unit is 1 time slot, each time domain period includes 14 time slots, and the third indication information includes 14 bits, each bit of which is used to indicate whether 1 time slot among the 14 time slots is the first time slot, and the first time slot is the time slot where the first resource is located.

[0132] Exemplarily, when the time domain unit is a time slot group, the time slot group refers to a set consisting of at least two consecutive time slots. Each time domain period includes 14 time slot groups, and the third indication information includes 14 bits, each of which is used to indicate whether one of the 14 time slot groups is a first time slot group, where the first time slot group is the time slot group where the first resource is located.

[0133] Exemplarily, when the time domain unit is 1 symbol, each time domain period includes 10 symbols, and the third indication information includes 10 bits, each bit of which is used to indicate whether 1 symbol among the 10 symbols is the first symbol, and the first symbol is the symbol where the first resource is located.

[0134] Exemplarily, when the time domain unit is a symbol group, the symbol group refers to a set consisting of at least two consecutive symbols. Each time domain period includes 10 symbol groups, and the third indication information includes 10 bits, each of which is used to indicate whether one of the 10 symbol groups is a first symbol group, where the first symbol group is the symbol group where the first resource is located.

[0135] According to the above method, when the time domain unit is a time slot, time slot resources that cannot be used to transmit communication signals can be obtained through the above method; when the time domain unit is a symbol, symbol resources that cannot be used to transmit communication signals can be obtained through the above method. On the one hand, the first resource is not used to transmit communication signals, which can ensure the quality and performance of communication signals and other signals in the system. On the other hand, by refining the time domain position indication of the unavailable resource to the symbol, more accurate unavailable resources can be obtained. When a time slot contains multiple symbols, by determining the symbols included in the first resource, and then using other symbols that are not the first resource to transmit communication signals, the resource utilization rate of communication signal transmission is improved. For example, when a time slot contains 14 symbols, 5 of which are first resources, the other 9 symbols of the time slot can still be used to transmit communication signals, thereby improving the resource utilization rate of communication signal transmission.

[0136] In some embodiments, the third indication information includes P bits, each of the P bits corresponds to two values, namely a first value and a second value, and the first value and the second value are different. For example, the first value can be 0 and the second value is 1. When the value of the bit corresponding to the domain unit is 1, the time domain unit is the first time domain unit, and when the value of the bit corresponding to the domain unit is 0, the time domain unit is not the first time domain unit. Alternatively, when the value of the bit corresponding to the domain unit is 0, the time domain unit is the first time domain unit, and when the value of the bit corresponding to the domain unit is 1, the time domain unit is not the first time domain unit. This application does not limit this.

[0137] In some embodiments, when the time domain unit is 1 time slot, illustratively, as shown in sub-figure (a) of FIG8 , each time domain cycle includes 5 time slots. Assume that in each time domain cycle, time slot 0 is time domain unit 0, time slot 1 is time domain unit 1, ..., and time slot 4 is time domain unit 4. Therefore, P is equal to 5, and the third indication information includes 5 bits. illustratively, the third indication information is "01100", so in each time domain cycle, time domain unit 1, i.e., time slot 1 (e.g., time slot 81, time slot 83), and time domain unit 2, i.e., time slot 2 (e.g., time slot 82, time slot 84), are the first time domain unit.

[0138] In some embodiments, if the time domain unit is a time slot group, illustratively, assuming that each time domain period includes 5 time slot groups, each time slot group includes 2 time slots, where time slot group 0 (including time slot 0 and time slot 1) is time domain unit 0, time slot group 1 (including time slot 2 and time slot 3) is time domain unit 1, ..., time slot group 4 (including time slot 9 and time slot 10) is time domain unit 4. Therefore, P is equal to 5, and the third indication information includes 5 bits. Exemplarily, the third indication information is "01100", so in each time domain period, time domain unit 1 (including time slot 2 and time slot 3) and time domain unit 2 (including time slot 4 and time slot 5) are the first time domain unit.

[0139] In some embodiments, if the time domain unit is 1 symbol, as shown in sub-figure (b) of Figure 8 , each time domain period includes 10 symbols, where symbol 0 is time domain unit 0, symbol 1 is time domain unit 1, ..., and symbol 9 is time domain unit 9. Therefore, P is equal to 10, and the third indication information includes 10 bits. Exemplarily, the third indication information is "0110000001", so in each time domain unit period, time domain unit 1, i.e., symbol 1 (such as symbol 85, symbol 88), time domain unit 2, i.e., symbol 2 (such as symbol 86, symbol 89), and time domain unit 9, i.e., symbol 9 (such as symbol 87, symbol 810) are the first time domain unit.

[0140] In some embodiments, if the time domain unit is a time symbol group, illustratively, it is assumed that each time domain period contains 5 symbol groups, each symbol group contains 2 symbols, wherein symbol group 0 (including symbol 0 and symbol 1) is time domain unit 0, symbol group 1 (including symbol 2 and symbol 3) is time domain unit 1, ..., symbol group 4 (including symbol 9 and symbol 10) is time domain unit 4. Therefore, P is equal to 5, and the third indication information includes 5 bits. Exemplarily, the third indication information is "01100", so in each time domain unit period, time domain unit 1 (including symbol 2 and symbol 3) and time domain unit 2 (including symbol 4 and symbol 5) are the first time domain unit. The above method refines the time domain position indication of the unavailable resource to the symbol, and can obtain a more accurate first resource that cannot be used to transmit communication signals. When a time slot contains multiple symbols, by determining the symbols included in the first resource, the symbols that are not the first resource can be used to transmit communication signals, thereby improving the resource utilization of communication signal transmission.

[0141] In some embodiments, the third indication information is used to determine a starting time domain position and / or number of the first time domain unit in the time domain period.

[0142] The starting time domain position refers to the time domain position occupied by the first first time domain unit among one or more first time domain units in the time domain. The first first time domain unit refers to the time domain unit corresponding to the earliest time or the latest time among the time domain units in each time domain period.

[0143] Exemplarily, when the time domain unit is 1 time slot, assuming that each time domain period includes 10 time slots and each time domain unit includes 1 time slot, time slot 0 is time domain unit 0, time slot 1 is time domain unit 1, ..., time slot 9 is time domain unit 9. The third indication information may indicate that the starting time domain position is time domain unit 0 (time slot 0) and the number is 3, then time slot 0, time slot 1, and time slot 2 are the first time domain unit.

[0144] Exemplarily, when each time domain unit is a time slot group, that is, a plurality of consecutive time slots, assuming that each time domain period includes 5 time slot groups, each time slot group includes 2 time slots, where time slot 0 and time slot 1 are time domain unit 0 (time slot group 0), time slot 2 and time slot 3 are time domain unit 1 (time slot group 1), ..., time slot 8 and time slot 9 are time domain unit 4 (time slot group 4). The third indication information may indicate that the starting time domain position is time domain unit 0 and the number is 2, so time domain unit 0 (time slot group 0, including time slot 0 and time slot 1) and time domain unit 1 (time slot group 1, including time slot 2 and time slot 3) are the first time domain unit.

[0145] Exemplarily, when the time domain unit is 1 symbol, assuming that each time domain period contains 10 symbols and each time domain unit contains 1 symbol, symbol 0 is time domain unit 0, symbol 1 is time domain unit 1, ..., symbol 9 is time domain unit 9. The third indication information may indicate that the starting time domain position is time domain unit 0 (symbol 0) and the quantity is 3, then symbol 0, symbol 1, and symbol 2 are the first time domain unit.

[0146] Exemplarily, when each time domain unit is a symbol group, that is, a plurality of consecutive symbols, assuming that each time domain period includes 5 symbol groups, each symbol group includes 2 symbols, where symbol 0 and symbol 1 are time domain unit 0 (symbol group 0), symbol 2 and symbol 3 are time domain unit 1 (symbol group 1), ..., symbol 8 and symbol 9 are time domain unit 4 (symbol group 4). The third indication information may indicate that the starting time domain position is time domain unit 0 and the number is 2, so time domain unit 0 (symbol group 0, including symbol 0 and symbol 1) and time domain unit 1 (symbol group 1, including symbol 2 and symbol 3) are the first time domain unit.

[0147] The above method can determine the first frequency domain resource unit based on the starting time domain position and / or number of the first time domain unit, and the first time domain unit is continuous. In this way, when there are many time domain units, fewer bits can be used to transmit the third indication information, which can save channel resources and bandwidth.

[0148] In some embodiments, the third indication information includes a second period, a second offset value and a second quantity; the second period is used to indicate the number of time domain units contained in each time domain period; the second offset value is used to indicate the position of the first first time domain unit in each time domain period; the second quantity is used to indicate the number of first time domain units in each time domain period.

[0149] Exemplarily, when the time domain unit is 1 time slot, in the third indication information, the second period may be 10, that is, the number of time slots included in each time domain period is 10. Assume that in each time domain period, time slot 0 is time domain unit 0, time slot 1 is time domain unit 1, ..., time slot 9 is time domain unit 9. In the third indication information, the second offset value may be 1, and the second number may be 2, that is, the first first time domain unit in each time domain period is time domain unit 1 (time slot 1), and the number of first time domain units is 2. Therefore, in each time domain period, time domain unit 1 (time slot 1) and time domain unit 2 (time slot 2) are first time domain units.

[0150] Exemplarily, when each time domain unit is a time slot group, that is, a plurality of consecutive time slots, in the third indication information, the second period may be 5, that is, the number of time slot groups contained in each time domain period is 5. Assume that in each time domain period, time slot 0 and time slot 1 are time domain unit 0, time slot 2 and time slot 3 are time domain unit 1, ..., time slot 8 and time slot 9 are time domain unit 4. In the third indication information, the second offset value may be 1, and the second number may be 2, that is, the first time domain unit in each time domain period is time domain unit 1 (time slot 2 and time slot 3), and the number of first time domain units is 2. Therefore, in each time domain period, time domain unit 1 (including time slot 2 and time slot 3) and time domain unit 2 (including time slot 4 and time slot 5) are first time domain units.

[0151] Exemplarily, when the time domain unit is 1 symbol, in the third indication information, the second period may be 10, that is, the number of time slots included in each time domain period is 10. Assume that in each time domain period, symbol 0 is time domain unit 0, symbol 1 is time domain unit 1, ..., and symbol 9 is time domain unit 9. In the third indication information, the second offset value may be 0, and the second number may be 2, that is, the first time domain unit in each time domain period is time domain unit 0 (symbol 0), and the number of first time domain units is 2. Therefore, in each time domain period, time domain unit 0 (symbol 0) and time domain unit 1 (symbol 1) are first time domain units.

[0152] Exemplarily, when each time domain unit is a symbol group, that is, a plurality of consecutive symbols, the second period in the third indication information may be 5, that is, the number of symbol groups contained in each time domain period is 5. Assume that in each time domain period, symbol 0 and symbol 1 are time domain unit 0, symbol 2 and symbol 3 are time domain unit 1, ..., symbol 8 and symbol 9 are time domain unit 4. In the third indication information, the second offset value may be 1, and the second number may be 2, that is, the first time domain unit in each time domain period is time domain unit 0 (symbol 0 and symbol 1), and the number of first time domain units is 2. Therefore, in each time domain period, time domain unit 1 (including symbol 2 and symbol 3) and time domain unit 2 (including symbol 4 and symbol 5) are first time domain units.

[0153] The above method can determine the first time domain unit according to the second period, the second offset value and the second quantity. This method can periodically determine the distribution and quantity of the first time domain unit, thereby improving the flexibility of the first time domain unit indication.

[0154] In some embodiments, the time domain information only includes the third indication information, and when the time domain unit is one or multiple consecutive time slots, when the one or multiple consecutive time slots are the first time domain unit, all symbols included in the one or multiple consecutive time slots are first resources.

[0155] In some embodiments, the time domain information includes fourth indication information, and the fourth indication information is used to determine the first time domain subunit in the first time domain unit, the first time domain unit is the time domain unit where the first resource is located, the first time domain subunit is the time domain subunit where the first resource is located, and each time domain unit includes multiple time domain subunits.

[0156] Each first time domain unit includes at least one time domain sub-unit. In this case, each of the one or more first time domain units may be a time slot or a time slot group (a plurality of consecutive time slots). Each time domain sub-unit in the at least one time domain sub-unit may be a symbol or a symbol group (a plurality of consecutive symbols).

[0157] In some embodiments, when the time domain information includes only the fourth indication information, the first time domain unit may be predetermined or indicated, for example, by agreement. The agreement may stipulate the first time domain unit in each time domain period, for example, the first two time domain units in each time domain period may be stipulated as the first time domain units, or the last two time domain units in each time domain period may be stipulated as the first time domain units, and this application does not limit this.

[0158] In some embodiments, the first time domain unit includes Q time domain sub-units, the fourth indication information includes Q bits, each of the Q bits is used to indicate whether a time domain sub-unit among the Q time domain sub-units is the first time domain sub-unit, and Q is a positive integer.

[0159] The one or more first time domain units include Q time domain sub-units, and each of the Q bits is used to indicate whether a time domain sub-unit among the Q time domain sub-units is a first time domain sub-unit.

[0160] When the time domain sub-unit is 1 symbol, the one or more first time domain units include Q symbols, and each of the Q bits is used to indicate whether one of the Q symbols is the first time domain sub-unit.

[0161] When the time domain sub-unit is a symbol group, the one or more first time domain units include Q symbol groups, and each of the Q bits is used to indicate whether a symbol group among the Q symbol groups is a first time domain sub-unit.

[0162] The above method locates the time domain position of the first resource at the time slot and symbol level according to the fourth indication information in the time domain information, which can achieve accurate positioning and efficient utilization of the first resource, thereby achieving the technical effect of improving resource utilization and data transmission efficiency.

[0163] In some embodiments, when a certain symbol group is the first time domain sub-unit, all symbols included in the symbol group are unavailable resources.

[0164] In some embodiments, the fourth indication information includes Q bits, each of the Q bits corresponds to two values, namely a first numerical value and a second numerical value, and the first numerical value and the second numerical value are different. For example, the first numerical value can be 0 and the second numerical value is 1. When the numerical value of the bit corresponding to the time domain sub-unit is 1, the time domain sub-unit is the first time domain sub-unit, and when the numerical value of the bit corresponding to the time domain sub-unit is 0, the time domain sub-unit is not the first time domain sub-unit. Alternatively, when the numerical value of the bit corresponding to the time domain sub-unit is 0, the time domain sub-unit is the first time domain sub-unit, and when the numerical value of the bit corresponding to the time domain sub-unit is 1, the time domain sub-unit is not the first time domain sub-unit, and this application does not limit this.

[0165] In some embodiments, Q is equal to the number of time domain sub-units included in the first time domain unit. When there is only one first time domain unit or when there are multiple first time domain units and the positions of the first time domain sub-units in the multiple first time domain units are the same, Q is equal to the number of time domain sub-units included in the first time domain unit. Exemplarily, it is assumed that each time domain period contains 10 time domain units, each time domain unit is a time slot, each time slot includes 14 symbols (time domain sub-units), and it is assumed that the first time domain units are time slot 1, time slot 2, and time slot 7. Therefore, the fourth indication information contains 14 bits, which can be "10010010011100", that is, time domain sub-unit 0 (symbol 0), time domain sub-unit 3 (symbol 3), time domain sub-unit 7 (symbol 7), and time domain sub-unit 8 (symbol 8) of time slot 1, time slot 2, and time slot 7 are first time domain sub-units.

[0166] In some embodiments, Q is equal to the product of the number of time domain sub-units included in the first time domain unit and the number of first time domain units. When there is one first time domain unit, Q is equal to the number of time domain sub-units included in the first time domain unit.

[0167] When there are multiple first time domain units, and the positions of at least two first time domain sub-units in the multiple first time domain units are different, illustratively, assuming that each time domain period includes 10 time domain units, each time domain unit includes 14 symbols (time domain sub-units), and assuming that the first time domain units are time slot 0 and time slot 1, that is, the number of first time domain units is 2, and the number of time domain sub-units included in each first time domain unit is 14. Therefore, the fourth indication information includes 28 bits and can be "10010010011100, 1001000000000", so time domain sub-unit 0 (symbol 0), time domain sub-unit 3 (symbol 3), time domain sub-unit 6 (symbol 6), time domain sub-unit 9 (symbol 9), time domain sub-unit 10 (symbol 10), and time domain sub-unit 11 (symbol 11) of time slot 0, and time domain sub-unit 0 (symbol 0) and time domain sub-unit 3 (symbol 3) of time slot 1 are first time domain sub-units.

[0168] When there are multiple first time domain units and the positions of the first time domain sub-units in the multiple first time domain units are the same, the fourth indication information can also be indicated in the above manner, that is, Q is equal to the product of the number of subcarriers contained in the first frequency domain resource unit and the number of first frequency domain resource units. This application does not limit this.

[0169] In the above method, when the positions of the first time domain sub-units in multiple first time domain units are the same, the fourth indication information includes fewer bits, which is beneficial to reducing the transmission overhead of the fourth indication information; when the positions of the first time domain sub-units in multiple first time domain units are different, the fourth indication information includes more bits, which improves the flexibility and diversity of the first time domain sub-unit indication.

[0170] In some embodiments, the time domain information includes third indication information and fourth indication information, the third indication information is used to determine the first time domain unit in each time domain period, and the fourth indication information is used to determine the first time domain subunit in the first time domain unit. Each time domain period contains 10 time domain units, each time domain unit contains 1 time slot, a time slot contains 14 symbols, and the position of the first time domain subunit in each time domain unit is the same. Exemplarily, the third indication information can be "0110000100", so the first time domain unit is time slot 1, time slot 2 and time slot 7, and the fourth indication information is "10010001100000", so the symbols 0, 3, 7 and 8 of time slot 1, time slot 2 and time slot 7 are the first time domain subunit.

[0171] In some embodiments, when the first information only includes frequency domain information, the frequency domain information is used to determine the frequency domain position of the first resource, as shown in sub-figure (a) of Figure 9 , assuming that the frequency domain position of the first resource is RBn, and in the entire time domain range, RBn is the first resource. When the first information only includes time domain information, the time domain information is used to determine the time domain position of the first resource, as shown in sub-figure (b) of Figure 9 , assuming that the time domain position of the first resource is time slot m, and in the entire frequency domain position, time slot m is the first resource. When the first information includes frequency domain information and time domain information, as shown in sub-figure (c) of Figure 9 , assuming that the frequency domain position of the first resource is RBn and the time domain position is time slot m, the final position of the first resource can be determined based on the frequency domain position and time domain position of the first resource.
