摘要
双流波束赋形是3GPP RAN1 R9的工作项目,目的是将LTE R8中的单流波束赋形扩展到双流,要求所有增强的能力在网络侧和终端侧均后向兼容R8。介绍了双流波束赋形的标准进展,并简要分析了相关的问题。
As a 3GPP Work Item, enhanced DL transmission for support of single-user dual-layer beamforming using UE-specific RS was agreed for R9. The objective of this work item is to support single user dual-layer beamforming using UE specific RS for both LTE-TDD and FDD. all new enhanced features and capabilities shall be backward compatible with networks and UEs compliant with LTE Release 8, and also should aim to be as an extension of the beamforming in Release 8. In this paper, the standard status of dual layer beamforming is introduced and some related problems are discussed.
