Description

Method for transmitting collaborative information, method for determining resources, communication nodes, and storage media The present application relates to the field of wireless communication networks, and, for example, to a method for transmitting collaborative information, a method for determining resources, a communication node, and a storage medium. In a sidelink communication system, traffic between User Equipment (UE) units is not forwarded via the network side—specifically, through the cellular link between the UE and the base station—but can be transmitted directly from the data source UE to the target UE via the sidelink. Sidelink communication not only conserves wireless spectrum resources but also reduces data transmission pressure on the core network, decreases system resource occupancy rates, increases spectrum efficiency, and reduces communication delays. During the sidelink communication process, the transmitting terminal monitors resource occupancy to select resources for signaling or data transmission; however, due to geographical location limitations, the transmitting terminal cannot observe actual interference regarding the geographical locations of one or more corresponding receiving terminals. Furthermore, the resources selected by the transmitting terminal may conflict with or interfere with resources transmitted by other terminals, thereby affecting the reliability of the sidelink communication.

The present application will be described below in combination with the attached drawings and embodiments. The specific embodiments described herein are used solely to illustrate the present application. For convenience of explanation, only the parts relevant to the present application are depicted in the drawings, rather than the entire structure. Sidelink communication has two resource allocation modes: scheduling by the base station and autonomous selection by the terminal. In the mode where the terminal makes autonomous selection, the terminal can monitor resource usage within the resource pool. Based on the monitoring results, the terminal can preferentially select resources that are not occupied by other terminals or have minimal transmission interference with other terminals, and use them for signaling or data transmission. The transmitting terminal must select a terminal to transmit positioning-related information. Due to the geographical location of the transmitting terminal, it cannot observe the actual interference situation regarding the geographical locations of one or more corresponding receiving terminals. Therefore, it is possible to find a collaborating terminal that provides collaboration information to the transmitting terminal and assists in the transmitting terminal's resource selection. However, there is no perfect solution for finding a suitable collaborating terminal when the transmitting terminal transmits information using group cast or broadcast methods. Embodiments of the present application provide a method for transmitting collaborative information applicable to a first terminal. For a transmitting terminal using a group cast method or a broadcast method, the first terminal can determine whether it is capable of acting as a collaborative terminal; if it is capable of acting as a collaborative terminal, it transmits collaborative information and recommends a set of resources suitable for the transmitting terminal, thereby reducing conflicts or interference between different resources and i
