Description

Methods and apparatus for determining sensing patterns This application claims priority to Chinese Patent Application No. 202411520272.4, filed on October 28, 2024, entitled "Method and Apparatus for Determining Sensing Mode", the entire contents of which are incorporated herein by reference. Technical Field This application relates to the field of wireless technology, and more specifically to a method and apparatus for determining a sensing pattern. Background Technology In the evolution of 5G technology, integrated communication and sensing technology is considered one of the key technologies for expanding the service capabilities of mobile communication networks. The core idea of this technology is to add sensing capabilities to the mobile communication network, building the ability to detect and image targets, thereby integrating communication and sensing capabilities into a single network, achieving harmonious coexistence and even mutual benefit. Based on whether the transmitting and receiving ends of the sensed signals are co-located or separate, sensing systems can be divided into monostatic systems and bistatic systems. Depending on whether the transmitting end is a terminal or a base station, monostatic and bistatic systems can be further subdivided into several more specific sensing modes. Different sensing modes have different characteristics, and determining the appropriate sensing mode for the current scenario is a problem that needs to be solved. Summary of the Invention Embodiments of this application provide a method, apparatus, system, computer-readable storage medium, and computer program product for determining a perception mode that is suitable for the current scenario. Firstly, embodiments of this application provide a method for determining a sensing mode. This method can be performed by a network device (e.g., a base station or core network element). Unless otherwise specified, "network device" in this application can refer to the network device itself, a component within the network device (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the network device's functions. The following description uses a base station as the executing entity. The method includes: obtaining the sensing service status of a target network device, whereby the sensing service status indicates whether the sensing function of the target network device is available, and a correspondence exists between the sensing service status and the sensing mode. In the above method, an alternative expression for "a correspondence exists between the perception service state and the perception mode" includes: determining the perception mode based on the perception service state. When the perception function of the target network device is unavailable, the base station needs to avoid using perception modes based on inter-base station perception functions, such as the base station-base station bi-base station mode; when the perception function of the target network device is available, the base station can use the base station-base station bi-base station mode as a candidate perception mode. Therefore, this embodiment determines the perception mode based on the perception service state, which can determine the perception mode suitable for the current scenario. In an optional implementation of the first aspect, when the sensing service status indicates that the sensing function is available, the sensing mode is a base station-to-base station dual-base mode or a base station single-base mode; or, when the sensing service status indicates that the sensing function is unavailable, the sensing mode is a base station single-base mode. In an optional implementation of the first aspect, the method further includes: acquiring channel measurement results of the cross-link of the target network device, the channel measurement results being used to determine the communication service status and/or the awareness service status. In this embodiment, the base station acquires the measurement results and determines the perception service status based on the measurement results, without needing to obtain the perception service status from other nodes, thus enabling the perception mode to be determined as quickly as possible. In an optional implementation of the first aspect, the method further includes: acquiring a first parameter of the cross-link, the first parameter being used to determine channel measurement results, the first parameter including at least one of the following parameters: Received Signal Strength Indicator (RSSI), Reference Received Power (RSRP), Channel State Information (CSI), Channel Quality Indicator (CQI), Signal-to-Interference-plus-Noise Ratio (SINR), Received Code Power (RSCP), or Reference Received Path Power (RSRPP). This embodiment provides more optional parameters for determining channel measurement results, improving the flexibility of the bas
