A method that involves obtaining spatial relation parameter information, determining transmission information based on resource indexes of reference signals, and using this information to accurately identify and configure optimal antenna panels and spatial characteristic parameters for both terminal and network devices, ensuring flexible and accurate beam training processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal device performs two measurements on a same reference signal by using different antenna panels, then the terminal device cannot determine a specific measurement and cannot determine optimal antenna panel information, but if the patent applies spatial relation parameter information including resource index of reference signal to identify antenna panels, then the terminal device can accurately determine optimal antenna panel information
Solution Approach 1:
The patent introduces spatial relation parameter information as an intermediary that includes the resource index of the reference signal. This intermediary establishes a clear mapping relationship between the reference signal and the antenna panel, allowing the terminal device to accurately determine which antenna panel should be used for measuring which reference signal, thereby resolving the ambiguity in multi-antenna panel measurement scenarios.
Solution Approach 2:
The patent segments the measurement process by associating different antenna panels with specific reference signals through spatial relation parameter information. Each antenna panel is clearly identified with its corresponding reference signal resource index, enabling the terminal device to perform measurements in a segmented, organized manner rather than attempting simultaneous measurements across all panels without clear assignment.

3Reliability
If the network device does not learn the identifier of the antenna panel used by the terminal device, then scheduling of uplink signals becomes difficult and link interruption may occur, but if the patent uses spatial relation parameter information to identify antenna panels, then the network device can accurately identify antenna panel information for scheduling
Solution Approach 1:
The spatial relation parameter information serves as an intermediary that carries the resource index of the reference signal and implicitly identifies the antenna panel. This intermediary allows the network device to learn the antenna panel identifier without requiring separate explicit signaling, as the spatial relation parameter information already establishes the mapping between reference signals and antenna panels used by the terminal device.
Solution Approach 2:
The system uses the existing spatial relation parameter information that the terminal device already maintains for its own beam management purposes. This information, which the terminal device uses to identify its own antenna panels and spatial characteristic parameters, also serves the additional function of enabling the network device to identify the antenna panel for scheduling decisions, eliminating the need for separate identification mechanisms.

AI summary
The present disclosure provides example communication method and apparatuses. One example method includes obtaining first spatial relation parameter information, where the first spatial relation parameter information is spatial relation parameter information of a first target signal, and the first spatial relation parameter information includes a resource index of a first reference signal. First transmission information is determined based on the resource index of the first reference signal, where the first transmission information includes at least one of first antenna panel information or a first spatial characteristic parameter. The first target signal is received or sent based on the first transmission information.
