摘要： A method, an apparatus, and a computer program product for wireless communication are provided in which a UE is equipped to receive first peer-to-peer communications using a first network communication channelization and a waveform, and transmit second peer-to-peer communications using a second network communication channelization and the waveform. Further, the UE may be equipped to map one or more channels in the second peer-to-peer communications to one or more uplink channels and/or downlink channels in the second network communication channelization. The second network communication channelization may include an LTE uplink/downlink channelization. The waveform may include OFDM or SC-FDM.

摘要： Blind interference cancellation is described for wireless networks in which a subject base station or cancellation apparatus obtains semi-static information for at least one of its neighboring cells. The base station measures the noise level of each of the neighboring cells based on samples it takes of uplink transmissions in each of the neighboring cells. The neighboring cells are then ranked for interference cancellation based on their relative noise levels. The base station performs discontinuous transmission (DTX) detection to identify at least one interfering user equipment (UE) in the neighboring cell and cancels interference attributable to those identified interfering UEs. The DTX detection and cancelation are then repeated for the remaining neighboring cells in the order they are ranked.

摘要： Systems and methodologies are described that facilitate unified, low-complexity processing (e.g., user separation and noise estimation) of a control channel. One or more UEs can respectively transmit one or more control signals, which are multiplexed on a control channel and a base station can receive a control channel signal that includes the one or more control signals. The base station, in a single pass, can separate the control signals by matching the control channel signal with a base sequence and translating the matched signal to a time-domain representation. In the time-domain representation, each control signal resides at a different tap. Further, the base station can identify taps of the time-domain representation corresponding to an unused cyclic shift or orthogonal cover sequence. Such taps can be employed to generate a noise and/or interference estimate.
摘要翻译：描述了促进控制信道的统一的，低复杂度处理（例如，用户分离和噪声估计）的系统和方法。一个或多个UE可以分别发射一个或多个控制信号，这些控制信号被多路复用在控制信道上，并且基站可以接收包括一个或多个控制信号的控制信道信号。基站在单次通过中可以通过将控制信道信号与基本序列匹配来分离控制信号，并将匹配的信号转换为时域表示。在时域表示中，每个控制信号驻留在不同的分接头。此外，基站可以识别对应于未使用的循环移位或正交覆盖序列的时域表示的抽头。可以使用这种抽头来产生噪声和/或干扰估计。

摘要： The present disclosure proposes design of a pico/femto uplink acknowledgement (ACK) channel that improves the interference suppression for pico/femto base stations. The proposed design provides a two-layered cell-separation ACK channel structure for femto/pico cells by using computer generated sequences (CGS) and Discrete Fourier Transform (DFT) spreading. Thereby, ACK channels may be multiplexed across different femto/pico base stations with minimal interference. The proposed scheme is compatible with conventional standards for the base station in the macro cell and does not impose any changes on the macro cell.
摘要翻译：本公开提出了改进对微微/毫微微基站的干扰抑制的微微/毫微微上行链路确认（ACK）信道的设计。所提出的设计通过使用计算机生成的序列（CGS）和离散傅里叶变换（DFT）扩展来为毫微微微微小区提供两层细胞分离的ACK信道结构。因此，可以以最小的干扰在不同毫微微微微基站之间复用ACK信道。所提出的方案与宏小区中的基站的常规标准兼容，并且不对宏小区施加任何改变。
