Abstract: A unified frame structure for filter bank multi-carrier (FBMC) and orthogonal frequency division multiplexed (OFDM) waveforms may allow FBMC and OFDM frames to be communicated over a common channel without significant inter-frame gaps. The unified frame structure may set an FBMC frame duration to an integer multiple of an OFDM frame element duration to enable alignment of FBMC frames and OFDM frames in the time domain. The unified frame structure may also map control channels in the FBMC and OFDM frames to common resource locations so that the respective control channels are aligned in the time and/or frequency domains. The unified frame structure may also share synchronization channels between FBMC and OFDM frames. Additionally, overhead in an FBMC time division duplexed (TDD) communications channel can be reduced by overlapping time windows appended to FBMC blocks.

Abstract translation: 用于滤波器组多载波（FBMC）和正交频分复用（OFDM）波形的统一帧结构可以允许FBMC和OFDM帧在公共信道上通信而没有显着的帧间间隙。 统一帧结构可以将FBMC帧持续时间设置为OFDM帧单元持续时间的整数倍，以使得时域中的FBMC帧和OFDM帧的对准。 统一的帧结构还可以将FBMC和OFDM帧中的控制信道映射到公共资源位置，使得相应的控制信道在时域和/或频域中对齐。 统一的帧结构也可以共享FBMC和OFDM帧之间的同步信道。 另外，FBMC时分双工（TDD）通信信道的开销可以通过将FBMC块附加的时间窗口重叠来减少。

Abstract: Embodiments are provided for early termination of an iterative process of determining channel directions and transmissions in multi-user multiple-input and multiple-output (MU-MIMO) communications systems. In an embodiment, a base station or a user equipment (UE) calculates a multi-user channel matrix using a first iteration of a null-space singular value decomposition (SVD) based iterative zero-forcing (I-ZF) algorithm for multi-user MU-MIMO. The base station or UE repeats updating the multi-user channel matrix using a next iteration of the algorithm and the multi-user channel matrix calculated in a previous iteration, until the diagonal elements of the multi-user channel matrix are greater than the off-diagonal elements by a predefined threshold. Upon determining that the diagonal elements are greater than the off-diagonal elements by the predefined threshold, a plurality of transmission signals are calculated using the last updated multi-user channel matrix.

Abstract: A uniform feedback format mandates that mandates that DPS CSI, JT CSI, and CQI are reported irrespective of which transmission scheme was previously used to perform transmissions. The DPS CSI, JT CSI, and CQI are then used to select a transmission scheme from a group of candidate transmission schemes. The selected transmission scheme can be a CoMP transmission scheme.
