摘要： Efficient apparatus and method for Zadoff-Chu (“Chu”) sequence generation avoids additional processing and hardware complexity of conventional quadratic generating formula followed by Discrete Fourier Transform (DFT) with a reference signal generator that produces both a Zadoff-Chu sequence and its DFT. In the wireless communication system (e.g., Long Term Evolution (LTE) system), Chu sequences are extensively used, especially in the uplink (UL). Because of the single carrier operating mode, transmitting a Chu sequence in principle involves a succession of generating that sequence, performing a DFT operation and then an IFFT operation. Assuming that the sequence length is N, the initial sequence generation requires 2N multiplications and the DFT requires more than N log 2(N) multiplications. Given the frequent processing of Chu sequences, this would represent a complexity burden. The invention makes it possible to perform the sequence generation and DFT steps without any multiplication operation, except for possibly calculating certain initial parameters.
摘要翻译：用于Zadoff-Chu（Chu）序列生成的高效装置和方法避免了常规二次生成公式的附加处理和硬件复杂性，随后是具有产生Zadoff-Chu序列及其DFT的参考信号发生器的离散傅里叶变换（DFT）。在无线通信系统（例如，长期演进（Long Term Evolution，LTE）系统）中，尤其在上行链路（UL）中广泛使用了Chu序列。由于单载波操作模式，原则上发送Chu序列涉及一系列生成该序列，执行DFT操作，然后进行IFFT操作。假设序列长度为N，则初始序列生成需要2N次乘法，并且DFT需要多于N个log 2（N）乘法。鉴于Chu序列的频繁处理，这将代表一个复杂的负担。除了可能计算某些初始参数之外，本发明使得可以执行没有任何乘法运算的序列生成和DFT步骤。

摘要： Methods and apparatuses are provided that include selecting reference signal (RS) or other tones to utilize in estimating a channel for decoding one or more channels. Where the RS tones are interfered by other base stations, interference cancelation can be performed over the RS tones. Since interference can vary over the tones, interference cancelation can yield RS tones of varying quality. Thus, a quality of each of the RS tones can be determined, and at least a subset of the RS tones can be selected for estimating a channel. Additionally or alternatively, the RS tones can be weighted or otherwise classified for performing channel estimation using the RS tones.
摘要翻译：提供了包括选择参考信号（RS）或其他音调以用于估计用于解码一个或多个信道的信道的方法和装置。在RS音调被其他基站干扰的情况下，可以通过RS音调进行干扰消除。由于干扰可以在音调上变化，所以干扰消除可以产生质量不同的RS音调。因此，可以确定每个RS音调的质量，并且可以选择RS音调的至少一个子集来估计频道。附加地或替代地，可以对RS音调进行加权或分类，以使用RS音调进行信道估计。

摘要： Carrier aggregation to enhance Evolved Multimedia Broadcast Multicast Service (eMBMS) includes transmitting unicast signaling for a unicast service on an anchor carrier to mobile entities, transmitting eMBMS signaling on a second carrier different from the anchor carrier to the mobile entities for use with the unicast signaling, and various techniques for practical application of carrier aggregation for eMBMS enhancement. In addition, allocating subframes used for MBMS on a Single Frequency Network (MBSFN) includes allocating at least a portion of one or more subframes otherwise reserved for unicast subframes on a mixed carrier to provide an increased allocation of subframes carrying MBSFN information, transmitting MBSFN signals on the increased allocation of subframes, and more detailed aspects.

摘要： Rather than attaching a preamble to a data traffic subpacket, a preamble channel is transmitted along with a traffic channel. In a system wherein the data traffic subpackets are variably sized, preambles can also be variably sized if a target station can decode variably sized preambles. A method and apparatus for decoding variably sized preamble subpackets are presented herein.

摘要： Aspects describe channel estimation in an OFDM system. Baseline DFT-based channel estimation can be performed and scaling can be applied to mitigate distortion in the DFT-based estimations. In some aspects, baseline DFT-based channel estimation can be performed and tones for which DFT-based estimate is deemed unreliable can have MMSE based processing applied locally. If orthogonal sequence is deemed excessive, orthogonal sequence cancellation can be applied prior to the MMSE based processing.
