A method and system to configure a group of user equipments (UE) for proximity services in a telecommunication system. The group of UEs are selected according to a combination of proximity to each other and also according to a directional relationship between them. The system may be used for device to device (D2D) communication in a 5G New Radio system. The advantages of the invention are said to be that it addresses shortcomings in discovery procedures related to the formation and management of Network-Controlled Interactive Services (NCIS) such as interactive gaming or data sharing. Examples of implementation of the invention are an interactive case whereby a user can share experiences via Augmented Reality/Virtual Reality (AR/VR) applications or public safety scenarios such as communication between an emergency vehicle and a crowd where discovery latency may be minimised and reliability of transmission ensured. The invention may utilise New Radio PC5 parameters such as range and directions of interest.
