摘要： Methods and apparatuses are provided that facilitate allocating a portion of a resource block to a power-limited device for communicating therewith. The power-limited device may not be capable of transmitting over an entire resource block due to power limitations; thus, a portion of the resource block can be assigned thereto, allowing for allocating at least a different portion of the resource block to at least one different device to optimize communications over the resource block. In addition, the portion of the resource block can be allocated across one or more bundled time transmit intervals (TTI) to allow for effective communication of time-sensitive data, such as voice over internet protocol (VoIP).

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： Systems and methodologies are described that facilitate adaptively communicating data to wireless devices. An access point can precode a dedicated reference signal (DRS) for transmitting to a wireless device, and the wireless device can receive the precoded DRS. The wireless device can determine the precoder by estimating a channel of the DRS and can provide channel condition feedback to the access point. The access point can create data signals including a single or a burst of data transmissions according to the feedback and can precode the data signals using the same precoder. The wireless device can additionally decode the data signals using the precoder. Moreover, the access point can cycle through precoders according to a patterned, random, pseudo-random, and/or similar sequence.
