Problems solved by technology

However, conventional systems do not consider inter-cell beam coordination
Dynamic "beam coordination" between neighboring UEs requires the execution of complex algorithms and real-time information exchange between BSs, adding overhead and making the system more complex

Embodiment Construction

[0018] In this patent document, the following description Figure 1 to Figure 8 , and the various embodiments illustrating the principles of the invention are by way of illustration only and should not be construed as limiting the scope of the invention. Those skilled in the art will understand that the principles of the invention may be implemented in any type of suitably arranged device or system.

[0019] Embodiments of the present disclosure provide a method for a user equipment (UE) to determine which rank indicator (RI), precoding matrix indicator (PMI) or RI / PMI pair to feed back to a base station (BS). During the determination process, the UE should not only consider its own receiving and transmitting performance (that is, individual optimization), but also consider minimizing the interference generated in other UEs due to the transmission from the BS to the UE (that is, system optimization). In determining, the UE utilizes an Interference Interaction Information (MI)...

Abstract

An apparatus in a user equipment (UE) node is configured to perform a method for channel feedback. The method includes determining, based on a common reference signal received from a base station and one or more channel conditions, a plurality of values for a receiver table. The method also includes determining a plurality of values for a decision table based on corresponding values in the receiver table and a predetermined interference table. The method further includes selecting a value from the decision table. In addition, the method includes transmitting, to the base station, at least one of a rank indicator (RI) value and a precoding matrix indicator (PMI) value associated with the selected value in the decision table.

Description

[0001] CROSS-APPLICATION OF RELATED APPLICATIONS AND CLAIMED PRIORITY [0002] This application claims priority to U.S. Nonprovisional Patent Application No. 14 / 685,077, filed April 13, 2015, entitled "System and Method for Intelligently Selecting RI / PMI," which claims April 14, 2014 Priority to U.S. Provisional Patent Application No. 61 / 979,362, entitled "Intelligent RI / PMI Selection," filed on May 1, 2009, both of which are incorporated herein by reference in their entirety. technical field [0003] The present disclosure basically relates to channel feedback in a wireless communication system, and in particular to a system and method for intelligently selecting a rank indicator (RI) and a precoding matrix indicator (PMI). Background technique [0004] In Long Term Evolution (LTE) downlink multiple-input multiple-output (MIMO) transmission mode, each user equipment (UE) node assigns the "optimal" rank indicator (RI) and / or precoding matrix indicator (PMI) Feedback to the ...
