The present invention relates to a method and apparatus for transmitting messages. A method for transmitting a message onto a time sensitive network, wherein the method comprises: receiving a message on a plurality of different channels; determining a frame time required to transmit a first received message from a first channel onto the network. If the frame time is greater than a predetermined maximum time period, maxInterferenceTime, permitted to transmit a single message within the network, then determining a minimum time, waitTime, until a second message on a second channel can become available for transmission. If the waitTime is greater than or equal to the difference between the frame time and the maxInterferenceTime, then transmitting the first message.

This invention discloses a dual-channel event-triggered unmanned surface vessel (USV) control method with minimum time interval, belonging to the field of USV control technology. To address the communication redundancy problem between USVs and between the controller and actuators, this invention establishes the assumptions of a dual-channel event-triggered USV control method with minimum time interval. Each USV is divided into follower and leader, and the motion dynamics equations for each USV are established. A weighted graph is constructed for the communication topology between USVs. Then, based on the definition of convex hull and the Laplace matrix, an event-triggered position observer with minimum time interval constraints is designed for each USV. An event-triggered tracking controller with minimum time interval is designed for the follower. This invention can significantly reduce the overall system requirement for expensive sensors and reduce the design and implementation costs of multi-USV systems.

This application provides a resource reservation method and terminal device, relating to the field of wireless communication technology. When reserving resources using a random resource selection method, this application selects candidate resources from a resource pool according to preset conditions. These conditions include: the time interval between two consecutive resource reservations using the random resource selection method is a preset time interval; or, the time interval between two consecutive resource reservations using the random resource selection method is greater than a preset minimum time interval; or, the priority of the candidate resource selected using the random resource selection method is a preset priority. Information transmission is then performed based on the candidate resources. This can reduce the probability of collisions between resources randomly selected and reserved by a terminal device that cannot perceive the resource and resources reserved by a terminal device that can perceive the resource.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate, with a network node, a first set of one or more messages according to a minimum time offset between a control message and a data message. The UE may transmit a communication status report in association with one or more conditions, associated with communications at the UE, being satisfied. The UE may communicate, with the network node, a second set of one or more messages according to an updated minimum time offset in association with transmitting the communication status report. Numerous other aspects are described.
