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: Embodiments of the present disclosure relate to transmission of sidelink feedback information on unlicensed spectrum. The first device transmits a configuration to a second device and a third device. The configuration indicates a primary resource and at least one backup resource, where the primary resource is to be used by the third device for transmitting feedback information of a sidelink transmission to the second device, the sidelink transmission being transmitted by the second device on an unlicensed resource, and the at least one backup resource is to be used by the third device for transmitting the feedback information of the sidelink transmission without performing a channel assessment.

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: 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.
