Background technique

With the development of communication technology, the 6G system will provide unprecedented functions and service capabilities. The ability to perceive will be an important feature of the 6G system. It is not only the basis for intelligent network applications, but also can serve the communication system itself and improve the system. performance. The perception capability will become the endogenous capability of the mobile communication system and will be deeply integrated with the communication capability. Among them, the integrated system of perception and communication refers to the integrated design of communication and perception functions through the joint design of signals or technologies such as hardware and spectrum sharing. Perceive information such as the direction, distance, and speed of the target, or detect, track, identify, and image the target device, event, or environment.

At present, perception is mainly used in radar systems. Compared with communication, it is independently designed according to different functions and frequency bands, that is, radar is used for target detection and identification, and communication is used for information transmission between devices. With the development of radar and communication technology, the difference between the two in the working frequency band and system composition is getting smaller and smaller, making the integrated system of perception and communication possible. However, there is still no effective solution on how to realize the perception function in the communication system.

An embodiment of the present disclosure provides a method for configuring a frame structure. FIG. 1 is a schematic flowchart of the method for configuring a frame structure in an embodiment of the present disclosure. As shown in FIG. 1 , the method includes:

Step 101: The communication device determines at least one flexible symbol in the frame structure as a perception symbol, and determines the perception direction of at least one perception symbol; the perception symbol is used to perceive target objects or environmental information.

At present, the communication system configures the frame structure in units of symbols, and the configuration of the transmission direction is more flexible. There are three configuration modes for 14 symbols in a time slot, namely uplink transmission, downlink transmission and flexible transmission. Based on this, the embodiment of the present disclosure adds a new kind of symbol, which is a perceptual symbol. On the premise of not changing the configuration of the existing frame structure, by configuring a flexible symbol (Flexible) as a perceptual symbol, the existing frame Realize the perception function structurally.

Exemplarily, the sensing or sensing function in this embodiment refers to collecting direct, reflected, and scattered signals of radio waves (or signals, sensing signals, etc.), and obtaining the target after detecting or processing the collected signals. Information such as the attributes and states of objects or environmental information, and then according to the perceived information, functions such as positioning, distance measurement, speed measurement, detection, and identification can be completed. In practical applications, the specific perception content can be related to business application scenarios.

In this embodiment, the communication device is a terminal device or a network device.

In some optional embodiments, when the communication device is a network device, the communication device determines that at least one flexible symbol in the frame structure is a sensing symbol, and determines a sensing direction of at least one sensing symbol, including: the network device Determining at least one flexible symbol in the frame structure as a sensing symbol by means of resource scheduling, and determining a sensing direction of the at least one sensing symbol.

In this embodiment, when a network device performs sensing, whether it is active sensing or passive sensing, the resources used for sensing do not need to be indicated to terminals within its network coverage, and the resources in the frame structure are determined by means of resource scheduling. At least one flexible symbol is a sensing symbol, that is, a flexible symbol not used for data transmission is multiplexed as a sensing symbol through resource scheduling, and the direction of the sensing symbol is further stipulated (or agreed, defined) as uplink transmission or downlink transmission.

The uplink transmission in this embodiment corresponds to sending a sensing symbol, and the downlink transmission corresponds to receiving a response signal of a sensing signal or receiving a communication signal reflected or scattered by a target, and the like.

In some other optional embodiments, when the communication device is a terminal device, the communication device determines that at least one flexible symbol in the frame structure is a sensing symbol, including: the terminal device receiving the first configuration information sent by the network device , determining at least one flexible symbol as a perceptual symbol based on the first configuration information.

In this embodiment, when the terminal device performs sensing, the network device needs to configure sensing resources for it. Optionally, if the terminal device has the sensing capability, the terminal device sends the sensing capability report result to the network device, and the network device determines that the terminal device has the sensing capability according to the sensing capability reporting result of the terminal device, and then sends the first configuration information.

In this embodiment, in order to ensure that the sensing function does not interfere with or seize normal communication resources, the network device configures and reuses flexible symbols not used for data transmission as sensing symbols through signaling, that is, sends the first configuration information to the terminal device through signaling. Wherein, the signaling may be the first high-layer signaling or the first physical layer signaling; exemplary, the first high-layer signaling may be RRC signaling, and the first physical layer signaling may be downlink control information (DCI, Downlink Control Information).

In this embodiment, the terminal device can determine at least one flexible symbol as a perceptual symbol through the parameters of the first high-layer signaling (specifically, RRC parameters, semi-static configuration mode); optionally, if the terminal device fails to pass the first high-layer If the signaling parameter determines the sensing resource, at least one flexible symbol may be determined as the sensing symbol through a dynamic indication of the first physical layer signaling, and this method may also be referred to as a dynamic configuration method.

In some optional embodiments of the present disclosure, the priority of the cell-specific RRC signaling, the priority of the SFI, the priority of the first high-layer signaling, and the priority of the first physical layer signaling gradually decrease; or,

In the related technical solution, the configuration mode of transmission resources includes semi-static configuration through RRC signaling and dynamic configuration through physical layer signaling (such as DCI), wherein RRC signaling includes cell public semi-static configuration and cell-specific semi-static configuration . The transmission mode of the uplink and downlink symbols configured through the cell public semi-static RRC signaling cannot be changed by other signaling; The static configuration or the DCI dynamic configuration is an uplink transmission symbol or a downlink transmission symbol. If a certain symbol is always configured as a flexible symbol, then this symbol is a reserved symbol, which is neither used for uplink nor downlink transmission.

In this embodiment, if the first high-level signaling or the first physical layer signaling occurs with cell-specific RRC signaling for semi-statically configuring communication symbols (such as uplink symbols and downlink symbols) and SFI for dynamically configuring communication symbols When there is a conflict, the priority order among the cell-specific RRC signaling, the priority of the SFI, the priority of the first higher layer signaling, and the first physical layer signaling satisfies any one of the above priority orderings.

Exemplarily, the cell-specific RRC signaling in this embodiment may specifically be TDD-UL-DL-ConfigDedicated.

In this embodiment, in order to determine whether the sensing direction of the sensing symbol is uplink or downlink, the network device configures the sensing direction of the sensing symbol through signaling, that is, sends the second configuration information through signaling.

In some optional embodiments, the terminal device receives the second configuration information sent by the network device, and determining the sensing direction of at least one sensing symbol based on the second configuration information includes: the terminal device receiving the second configuration information sent by the network device Two high-layer signaling or second physical layer signaling; determine the sensing direction of at least one sensing symbol based on the parameters of the second high-layer signaling, or determine the sensing direction of at least one sensing symbol based on the indication of the second physical layer signaling Perceived direction.

In this embodiment, the terminal device can determine the sensing direction of at least one sensing symbol through the parameters of the second layer signaling (specifically, RRC parameters, semi-static configuration); optionally, if the terminal device fails to pass the second layer The signaling parameter determines the sensing direction of the at least one sensing symbol, and then the sensing direction of the at least one sensing symbol may be determined through an indication of the second physical layer signaling. This manner may also be called a dynamic configuration manner.

Wherein, for example, the second high layer signaling may be RRC signaling, and the second physical layer signaling may be DCI.

In this embodiment, the system parameters of the sensing symbols are the same as the transmission symbols of the data transmission, and the system parameters include parameters such as subcarrier spacing and the number of symbols in a time slot.

In some optional embodiments, the method may further include: the terminal device receiving third configuration information sent by the network device, the third configuration information including at least one of the following information: transmission direction of communication symbols, time Slot configuration cycle, number of uplink and downlink time slots, number of uplink and downlink symbols, number of uplink and downlink perception symbols, etc.

In some optional embodiments, the method further includes: the communication device sends a first signal, and the first signal is used for a sensing function; the communication device receives a first response signal corresponding to the first signal, The first response signal is a signal after the first signal is reflected or scattered by a target; the communication device obtains perception information based on the first response signal; the first signal is sent through a perception symbol; the second A response signal is received via the sensory symbol.

This embodiment is a technical solution for active sensing of a communication device. In the active sensing process, the communication device, as a sensing active party, sends a signal for the sensing function, that is, sends a first signal for the sensing function through a sensing symbol. Exemplarily, when the communication device is a terminal device, the terminal device may generate a sensing signal sequence (that is, a first signal) according to a sensing signal configuration parameter configured by the network device, and send the first signal through a sensing symbol used for uplink transmission. When the communication device is a network device, the network device may generate a sensing signal sequence (ie, a first signal) according to specified (or agreed, defined) sensing signal configuration parameters, and send the first signal through a sensing symbol for uplink transmission. After the first signal is sent, it is reflected or scattered by the target object in the environment, and the communication device receives the first response signal through the sensing symbol used for downlink transmission.

For example, the terminal device sends the first signal through the sensing symbol used for uplink transmission, and the terminal device receives the first response signal in the sensing symbol used for downlink transmission, and/or, the network device or other terminal device uses The sensing symbol for downlink transmission receives the first response signal, so as to obtain sensing information (such as speed information, distance information, etc.).

In other optional embodiments, the method further includes: the communication device receives a second signal through the sensing symbol, and the second signal is a sensing signal reflected or scattered by the target object, or is a signal received by other communication devices A sensing signal sent out, where the sensing signal is a signal for a sensing function; the communication device obtains sensing information based on the second signal.

This embodiment is a technical solution for passive sensing of a communication device. In the passive sensing process, the communication device (terminal device and/or network device) does not need to send a signal for the sensing function, but receives a second signal in the sensing symbol for downlink transmission, and the second signal can be the target object Reflected or scattered sensing signals, or sensing signals emitted by other communication devices, etc.
