DEVICES AND METHODS FOR NETWORK ASSISTED MIMO RECEIVER ANTENNA PORT SWITCHING

摘要

Embodiments are related to systems, methods, and computer-readable media to configure a User Equipment (UE) device for full receive antenna port operating mode or partial receive antenna port operating mode. In one embodiment a UE comprises control circuitry configured to manage receipt of a network command signal from an evolved Node B (eNB). The command signal instructs the UE to switch between a full port operating mode and a partial port operating mode for a plurality of antenna ports. It also instructs the UE to adjust power for at least a part of a Multiple-Input Multiple-Output (MIMO) receiver such that in the full port operating mode the MIMO receiver is configured to actively receive on all of the antenna ports and in the partial port operating mode the MIMO receiver is configured to actively receive on a portion of the antenna ports.
