Scheduling algorithms for cooperative beamforming

摘要

Certain aspects of the present disclosure support techniques for cooperative beamforming based on inter-cell coordination. Signaling design allows coordinated downlink transmissions with reduced inter-cell interference.

主权项

1. A method for wireless communications, comprising:
receiving, at a cell, one or more Spatial Feedback Information (SFI) messages from one or more user terminals served by a neighboring cell, wherein each SFI message was transmitted in response to a Request by the neighboring cell to deliver Spatial Feedback Information (SFI-REQ) to one or more interfering cells of the user terminals, and wherein the SFI message comprises information about a channel between one of the user terminals and the cell; and adjusting at least one of a beam direction or a power for data transmission based on the SFI messages.
