    Abstract: An apparatus for adaptively defining clusters transmit points for coordination in a communication network includes a circuit that receives radio frequency channel information corresponding to the transmit points and defines a subset of the transmit points based at least in part on the radio frequency communication channel information. The subset is interrelated by a contiguous chain of dominant interference relationships between pairs of the transmit points. The apparatus further includes a processor that independently coordinates radio communications among the subset of transmit points.

    Abstract: A first device receives a first signal sent by a second device, receives a second signal sent by a third device, and determines a first length based on first time, second time, and delay duration. The first time is time at which the first device receives the first signal. The second time is time at which the first device receives the second signal. The first length is a distance from an intersection point of a first straight line on which a terminal device is located and a first transmission line between a first network device and a second network device to the second network device, and the first straight line is perpendicular to the first transmission line.

    Abstract: The present invention provides methods, apparatuses and systems supporting in-order packet delivery during application relocation or UP (User Plane) path management events such as DNAI (Data Network Access Identifier) changes. In-order packet delivery may be enforced, ensured or supported by using an indication that in-order packet delivery is requested or required for a particular traffic flow of a UE during a user plane path management event. The methods may be performed by apparatuses implementing an application function (AF), a policy control function (PCF), a session management function (SMF), or UP entities such as PDU session anchors, of the communication network, or systems implementing a combination thereof. The SMF may configure UP entities to transmit packets and flow end markers to support in-order packet delivery and provide flow end marker information to the UP entities. The UP entities may signal path changes using flow end markers.
