In accordance with example embodiments of the invention there is at least a method and apparatus to perform determining, by a network node, context information of a group of more than one user equipment, wherein the context information is based on at least service related information associated with the more than one user equipment; sending information comprising the context information towards at least one base station of a communication network; and based on the context information, negotiating with the at least one base station timing synchronization requirements for distribution to each user equipment of the group. Further, there is at least a method and an apparatus to perform receiving from a network node, by a network device of a communication network, information comprising context information associated with a group of more than one user equipment, wherein the context information is based on at least service related information associated with the more than one user equipment; based on the information, negotiating with the network node timing synchronization requirements for distribution to each user equipment of the group; and in response to the negotiating, selecting at least one network device of the communication network for the distribution by the at least one network device of the timing synchronization requirements to each user equipment of the group of more than one user equipment.
