Abstract: In a system, apparatus, method, and non-transitory computer readable medium for implementing SL DRX reconfiguration for SL groupcast based on congestion control, a UE device may be caused to, obtain sidelink (SL) groupcast configuration information associated with a desired UE group, the SL groupcast configuration information including a SL discontinuous reception (DRX) cycle and at least one setting rule regarding the SL DRX cycle for the desired UE group, the SL DRX cycle including a SL DRX ON duration setting, determine whether a congestion level of the desired UE group for a current SL DRX cycle period exceeds a desired congestion threshold level, determine SL DRX reconfiguration settings based on results of the determining whether the congestion level exceeds the desired congestion threshold level and the setting rule, and perform SL DRX communication based on the determined SL DRX reconfiguration settings.

Abstract: There is provided an apparatus which is a first apparatus comprising one or more processors, and one or more memories storing instructions that, when executed by the one or more processors, cause the first apparatus at least to perform: detecting at least one join request broadcasted by at least one second apparatus, wherein the at least one join request is indicative of a request to join a sidelink reference signal exchange session; transmitting a response to the at least one second apparatus, wherein the response is indicative at least of an identity of the first apparatus; receiving, from at least one second apparatus, a first configuration set comprising an identity of at least one first apparatus paired with a sidelink reference signal configuration; receiving at least one further message indicative of one or more sidelink reference signal configurations; and based at least on the first configuration set and the at least one further message, selecting at least one non-conflicting sidelink reference signal configuration for the sidelink reference signal exchange session with the at least one second apparatus.

Abstract: A method and apparatus are provided for determining an active time of a user equipment to which a sidelink communication is to be sent. A sidelink resource allocation request is generated requesting allocation of a resource for transmitting this sidelink communication, the sidelink resource allocation request having an indicator indicative of the determined active time of the user equipment.
