Title
(EN) FORMING A VIRTUAL USER EQUIPMENT GROUP AND ENHANCING COMMUNICATION USING JOINT RECEPTION AND TRANSMISSION MECHANISMS
Abstract
(EN)

Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for forming a virtual user equipment (UE) group and enhancing communication using joint reception and transmission mechanisms. For example, a UE may establish sidelink channels for communications with one or more other UEs. The UE and the one or more other UEs may form a virtual UE group (also interchangeably referred to as a virtual UE) using the sidelink channels. The UE may exchange information with other UEs in the virtual UE group to enhance communications between the one or more UEs of the virtual UE group and a network entity. The information exchanged depends on at least one of a joint reception mechanism or a joint transmission mechanism used by the virtual UE group. The UE communicates with the network entity based, at least in part, on the exchanged information.
