Techniques for beamforming to mitigate multi-user leakage and interference

摘要

Examples are disclosed for beamforming to mitigate multi-user leakage and interference. The examples include an evolved node B (eNB) receiving feedback from user equipment (UEs) to indicate strongest or highest channel gains for various beams included in a plurality of beam sets. A selection process or scheme may then be implemented to select individual beams for a UE that minimizes or reduces leakage caused by the UE's use of a given beam. Reducing leakage may reduce interference to other UEs using other beams. Other examples are described and claimed.

1. At least one non-transitory machine readable medium comprising a plurality of instructions that, in response to being executed at user equipment (UE) capable of operating in compliance with one or more 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) standards including LTE-Advanced (LTE-A), cause the UE to:
receive a plurality of reference symbols from an evolved node B (eNB) via separate beams, each beam associated with one of a plurality of beam sets; select a beam from each beam set according to a defined parameter; report the selected beams to the eNB; receive precoding weights for a given beam of the reported beams from the eNB, the given beam selected from among the plurality of beams based on the given beam causing no interference to other beams from among the plurality of beams selected for other UEs that is above a given interference threshold; and receive data from the given beam using the precoding weights.
