The embodiments of this application can also be applied to these communication systems.

[0056] Optionally, the communication system in this application embodiment can be applied to carrier aggregation (CA) scenarios, dual connectivity (DC) scenarios, or standalone (SA) network deployment scenarios.

[0057] Reference Figure 1 , Figure 1 This is a schematic diagram of the architecture of a data transmission system provided in this embodiment. The data transmission system provided in this embodiment includes a terminal device 101 and a network device 102.

[0058] Optionally, terminal equipment 101 can be various forms of user equipment, access terminal, user unit, user station, mobile station, mobile station (MS), remote station, remote terminal, mobile device, terminal equipment, wireless communication equipment, user agent, or user device. It can also be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, PDA, handheld device with wireless communication capabilities, computing device, or other processing device connected to a wireless modem, in-vehicle device, wearable device, terminal equipment in future 5G networks, or terminal equipment in future evolved Public Land Mobile Networks (PLMNs), etc. This application embodiment is not limited in this regard, as long as the terminal equipment can wirelessly communicate with network equipment 102.

[0059] Optionally, network device 102, also known as public mobile communication network device, is the interface device for terminal device 101 to access the Internet. It is also a type of radio station, which refers to a radio transceiver station that transmits information to and from terminal devices within a certain radio coverage area. This includes base stations (BS), also known as base station equipment, which is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, in 2G networks, devices providing base station functionality include Base Transceiver Stations (BTS); in 3G networks, NodeBs; in 4G networks, evolved NodeBs (eNBs); in Wireless Local Area Networks (WLANs), access points (APs) provide base station functionality; in 5G NR, gNBs provide base station functionality, and further evolved NodeBs (ng-eNBs) provide base station functionality. The gNB communicates with terminal devices using NR technology, while the ng-eNB communicates with terminal devices using Evolved Universal Terrestrial Radio Access (E-UTRA) technology. Both gNBs and ng-eNBs can connect to the 5G core network. The network device 103 in this embodiment also includes devices providing base station functionality in future new communication systems.

[0060] In this application embodiment, the one-way communication link from the access network to the terminal device is defined as the downlink (DL), and the data transmitted on the downlink is called downlink data, and the transmission direction of the downlink data is called the downlink direction; while the one-way communication link from the terminal device to the access network is defined as the uplink (UL), and the data transmitted on the uplink is called uplink data, and the transmission direction of the uplink data is called the uplink direction; the terminal device can also communicate directly with the terminal device, and the link between the terminal devices is called the sidelink (SL).

[0061] In Time Division Duplex (TDD) mode, terminal devices can perform uplink and downlink transmissions on the same frequency band. According to the 3rd Generation Partnership Project (3GPP) NR protocol, the frame structure can adopt either semi-static configuration or dynamic indication. The uplink and downlink allocation within each time slot, in chronological order, can contain N1 downlink symbols, N2 flexible symbols, and N3 uplink symbols; where N1, N2, and N3 are greater than or equal to 0.

[0062] In semi-static configuration, network devices configure a periodic frame structure via Radio Resource Control (RRC) signaling, with one or two consecutive uplink / downlink patterns within each period. Each uplink / downlink pattern consists of uplink / downlink allocation methods for multiple consecutive time slots, and the configuration ensures that each uplink / downlink pattern contains downlink symbols, flexible symbols, and uplink symbols in chronological order.

[0063] To better understand the embodiments of this application, please refer to... Figure 2 , Figure 2 This is a schematic diagram of an uplink / downlink pattern provided in an embodiment of this application.

[0064] exist Figure 2 In this pattern, each uplink and downlink pattern includes N1 downlink symbols (D), N2 flexible symbols (X), and N3 uplink symbols (U).

[0065] In dynamic configuration, network devices periodically indicate an uplink / downlink pattern through downlink control information (DCI), which can be composed of uplink / downlink allocation methods for multiple consecutive time slots.

[0066] In some embodiments, if the terminal device needs to perform point-to-point communication, the network device can configure the terminal to perform uplink and sidelink transmissions on the same carrier. According to the 3GPP NR protocol, the base station configures a continuous segment of symbols within a time slot through RRC signaling, and the uplink symbols within this continuous segment are used for sidelink transmission.

[0067] Synesthesia fusion refers to the integration of communication and sensing functions. Communication functions enable communication between different devices (such as between terminal devices and network devices, or between terminal devices). Sensing functions are used to perceive the physical characteristics of the surrounding environment and influence communication, thus achieving mutual enhancement between the two functions.

[0068] Currently, terminal devices communicate by sending or receiving communication signals (i.e., electromagnetic signals) and perceive their surroundings by sending sensing signals. Therefore, research on time-domain resource allocation, particularly for terminal devices with both communication and sensing capabilities, to achieve sensory fusion is a pressing technical challenge.

[0069] To address the aforementioned technical problems, this application provides a communication method in which a network device determines time-domain resource indication information and sends this information to a terminal device. This helps the terminal device transmit sensing signals and communication signals on the same carrier, achieving sensor-communication fusion. Detailed embodiments are described below.
