A method and device are disclosed for PC5 Signaling (PC5-S) message transmission from the perspective of a first User Equipment (UE). In one embodiment, the first UE communicates with a second UE via a UE-to-UE relay. The first UE also transmits a first PC5-S message on a first sidelink Signaling Radio Bearer (SRB) to the UE-to-UE Relay, wherein the first PC5-S message is used to establish a first sidelink security between the first UE and the UE-to-UE relay, to update link identifier(s) associated with a first link between the first UE and the UE-to-UE relay, or to modify the first link between the first UE and the UE-to-UE relay.

Aspects of the disclosure provide for controlling an autonomous vehicle to respond to queuing behaviors at pickup or drop-off locations. As an example, a request to pick up or drop off a passenger at a location may be received. The location may be determined to likely have a queue for picking up and dropping off passengers. Based on sensor data received from a perception system, whether a queue exists at the location may be determined. Once it is determined that a queue exists, it may be determined whether to join the queue to avoid inconveniencing other road users. Based on the determination to join the queue, the vehicle may be controlled to join the queue.

A method and apparatus for regenerating disaster information by adding information on an actual situation of a personal interest area to basic disaster information. In order to generate disaster information that meets interests of various individuals, the disclosure suggests a method for collecting and managing information on an interest area of an individual in advance, and collecting, analyzing and managing information measured by various measurers and sensors installed in the interest area. When a serious or urgent disaster occurs or is predicted and disaster information is provided, information collected in an interest area of an individual is combined with basic disaster information to transmit personalized disaster information.
