UE GROUPS, UE GROUP MANAGER UEs AND UE GROUP MEMBER UEs

A base station for a cellular network, wherein the base station is configured to

• communicate with one or more User Equipments—UEs—of a UE Group,
• wherein the base station comprises
• a first mode in which the base station coordinates the communication with the one or more UEs of the UE Group,
• and a second mode in which the base station is configured to appoint a predetermined UE for coordinating the communication within the UE Group.

A cellular network comprising:

• a first User Equipment—UE—for a cellular network, the first UE comprising
• a first interface for UE-to-Basestation communication configured to communicate with a base station of the cellular network, and
• a second interface for UE-to-UE communication configured to communicate with one or more other UEs of a UE-Group to which the first UE belongs,
• wherein the first UE is configured to receive via its first interface configuration data for configuring its second interface, and to coordinate, via the second interface, a communication within the UE Group,
• and further comprising
• a second User Equipment—UE—for the cellular network, the second UE comprising
• a first interface for UE-to-Basestation communication configured to communicate with a base station of the cellular network, and
• a second interface for UE-to-UE communication configured to communicate with one or more other UEs of the UE Group to which the first and second UE belong,
• wherein the second UE is configured to communicate via its second interface with at least one or more of the other UEs of the UE Group, wherein the communication is coordinated by the first UE,
• and further comprising
• a base station for the cellular network, wherein the base station is configured to
• communicate with one or more User Equipments—UEs—of the UE Group,
• wherein the base station comprises
• a first mode in which the base station coordinates the communication with the one or more UEs of the UE Group,
• and a second mode in which the base station is configured to appoint the first UE for coordinating the communication within the UE Group.
