Abstract: Systems, methods, apparatuses, and computer program products for radio resource reservation for inter-UE coordination in NR sidelink mode 2. The method may include transmitting from a first user equipment to a second user equipment, a first coordination request to request a set of preferred or non-preferred radio resources for transmission by the first user equipment. The first coordination request may include at least a first resource indication value for indicating a first radio resource for transmission of a corresponding first coordination message by the second user equipment to the first user equipment. The method may also include receiving the corresponding first coordination message from the second user equipment transmitted on the first radio resource in response to the first coordination request.

Abstract: A user equipment method and computer program are disclosed. The user equipment comprising means for: generating a coordination request for information on resources for use for direct inter user equipment transmissions, the coordination request including an indication of a preference for resources for receiving a coordination response; monitoring for coordination requests made by at least one other user equipment; generating the resource preference indication in dependence upon at least one preference indication from at least one of the monitored coordination requests. A coordinating user equipment for receiving and responding to the coordination requests by multiplexing response together is also disclosed.

Abstract: Apparatus and method for inter-UE coordination in groupcast transmissions are provided. Solution comprises communicating (400) with a group of apparatuses in a group communication utilising sidelink transmission, where the group of apparatuses comprises a second apparatus configured to coordinate resource allocation for the group communication and at least one other first apparatus; transmitting (402), utilising a designated hybrid automatic repeat request process, an inter-UE coordination request. Positive or negative hybrid automatic repeat request acknowledgements are received (404) from the group of apparatuses in response to transmitting the inter-UE coordination request and monitoring of inter-UE coordination requests of the at least one other first apparatus are monitored (406) based on the received acknowledgements from the at least one other first apparatus

Abstract: Disclosed is a method for efficient signaling of sidelink radio resources. A first terminal device selects a subset of radio resources from a set of candidate radio resources. The first terminal device determines a set of resource indices for the subset of radio resources based at least partly on a pre-defined enumeration order of the set of candidate radio resources in time and frequency. The first terminal device determines a first resource indication value indicating at least the set of resource indices. The first terminal device transmits the first resource indication value to one or more second terminal devices.
