Abstract: Beamforming may be used in MIMO communication systems to further enhance spectral efficiency. Beamforming refers to beamed transmissions to a single destination (e.g., a station) at a time, to enhance the rate and/or range of transmission. To perform beamforming from a source to one or more destinations, a channel and/or beamforming matrices corresponding to the channel needs to be known at the source, which may be obtained as feedback from the destination. However, the beamforming matrices may not be smooth over frequency as it is fed back from the destination. Therefore, certain aspects of the present disclosure provide beamforming feedback options, resulting in the smoothness of a beamforming matrix.

Abstract translation: 波束形成可以用于MIMO通信系统中以进一步提高频谱效率。 波束成形是指一次向单个目的地（例如，站）的波束传输，以增强传输的速率和/或范围。 为了从源到一个或多个目的地执行波束成形，需要在源处知道对应于该信道的信道和/或波束成形矩阵，其可以作为来自目的地的反馈获得。 然而，当从目的地反馈时，波束形成矩阵可能不是频率上的平滑。 因此，本公开的某些方面提供波束成形反馈选项，导致波束形成矩阵的平滑度。
