This document describes methods, devices, systems, and means for performing a regrouping of a user equipment (UE) (113) between user equipment-coordination sets (UECS) by a base station (121) in which the base station (121) determines to regroup a user equipment (113) from a source UECS to a target UECS and transmits a release message to a coordinating UE (111) of the source UECS requesting the coordinating UE (111) of the source UECS to release the user equipment (113) from the source UECS (605). The base station (121) transmits a request message to a coordinating UE (114) of the target UECS requesting the coordinating UE (114) of the target UECS to add the user equipment (113) to the target UECS (610), and transmits a regrouping message to the user equipment (113) that is effective to direct the user equipment (113) is to perform a regrouping from the source UECS to the target UECS (615).
