摘要： Reported CSI may not reflect non-cancelable CRS interference received from an interfering cell, such as when the CSI is computed when CRS interference is not received. To address the issue, a user equipment (UE) may determine an interference cancelation/suppression efficiency (CSE) associated with canceling/suppressing interference from interfering cells. In addition, based on the determined CSE, a UE may compute CSI such that the CSI reflects the true cancelation efficiency of the UE with respect to interfering cell signals. When computing the CSI based on the determined CSE, the UE may report that the CSI is worse than it is to reflect the UE's true cancelation efficiency with respect to the interfering cell signals.
摘要翻译：报告的CSI可能不反映从干扰小区接收的不可取消的CRS干扰，例如当没有接收到CRS干扰时计算CSI。为了解决该问题，用户设备（UE）可以确定与抵消/抑制来自干扰小区的干扰相关联的干扰消除/抑制效率（CSE）。另外，基于所确定的CSE，UE可以计算CSI，使得CSI相对于干扰小区信号反映UE的真实消除效率。当基于确定的CSE计算CSI时，UE可以报告CSI比反映UE相对于干扰小区信号的真实消除效率更差。

摘要： A method and apparatus are provided for reducing the number of pilot symbols within a MIMO-OFDM communication system, and for improving channel estimation within such a system. For each transmitting antenna in an OFDM transmitter, pilot symbols are encoded so as to be unique to the transmitting antenna. The encoded pilot symbols are then inserted into an OFDM frame to form a diamond lattice, the diamond lattices for the different transmitting antennae using the same frequencies but being offset from each other by a single symbol in the time domain. At the OFDM receiver, a channel response is estimated for a symbol central to each diamond of the diamond lattice using a two-dimensional interpolation. The estimated channel responses are smoothed in the frequency domain. The channel responses of remaining symbols are then estimated by interpolation in the frequency domain.

摘要： The present invention relates to the technical field of radio communications, and specifically relates to a method, device, and system for transmitting a reference signal, for use in solving the problem in the prior art that vertical-dimension channel estimation cannot be supported and thus 3D beamforming is not supported. The method of embodiments of the present invention comprises: a network side determines a subframe (31) used for bearing the reference signal, determines a pilot frequency port (32) of the reference signal, and transmits in the determined subframe the reference signal configured in the pilot frequency port, where all of the pilot frequency ports comprise at least one row of horizontal-dimension pilot frequency ports and one column of vertical-dimension pilot frequency ports, the reference signal configured in the horizontal-dimension pilot frequency ports is a horizontal-dimension reference signal, and the reference signal configured on the vertical-dimension pilot frequency ports is a vertical-dimension reference signal (33). Because the embodiments of the present invention are capable of transmitting the vertical-dimension reference signal, implementation of channel estimation on the vertical-dimension pilot frequency ports is allowed, and implementation of a dynamic 3D beamforming technology is allowed.
