1. A user equipment comprising:
- antenna elements comprising a first antenna element; and
a processor configured to;
receive, from a base station, information identifying an active set of one or more serving nodes to provide transmission service to the user equipment;
determine a selected mode of wirelessly receiving data using the first antenna element, the selected mode being either a coordinated multipoint mode or an alternate downlink data transmission mode, wherein the processor is configured to determine that the selected mode is the coordinated multipoint mode based on a mobility measurement being less than a first threshold and channel state information variation being less than a second threshold; and
cause transmission, via at least one of the antenna elements, of a request to receive data at the first antenna element in the selected mode.

Abstract
Aspects of this disclosure relate to user equipment assisted multiple-input multiple-output (MIMO) downlink configuration. Features are described for a user equipment determination of a desired transmission mode and/or active set of serving nodes for wireless communication service(s). The user equipment may submit a request for the desired mode and/or nodes to a network controller such as a baseband unit. The user equipment may subsequently receive a configuration for the requested wireless communication service(s).
