CPC Class H04W

A method for operating a transmitting user equipment (TX UE) in a wireless communication system, according to one embodiment, comprises: a step in which the TX UE transmits sidelink control information (SCI); a step in which the TX UE transmits predetermined data in a resource region associated with the SCI; and a step in which, on the basis of feedback of a receiving (RX) UE which has received the data, the TX UE determines declaration of a sidelink radio link failure (RLF), wherein the predetermined data is transmitted on the basis of there being no data for the TX UE to transmit to the RX UE, and the predetermined data is associated with a trigger of the feedback.

A method is provided of managing a non-static collection of machines. A first client machine runs a first communication protocol. The non-static collection of machines includes a first linear communication orbit, the first linear communication orbit comprising a sequence of machines that run the first communication protocol, and a second linear communication orbit, the second linear communication orbit comprising a sequence of machines that run a second communication protocol distinct from the first communication protocol. The first client machine receives an instruction from a server to install the second communication protocol, installs the second communication protocol, and then submits a registration request to the server. The first client machine receives, from the server, contact information of a list of potential neighbors. The first client machine then, proactively constructs and maintains a respective local segment of the second linear communication orbit.
