摘要： Techniques for assigning multipaths to finger processors to achieve the desired data performance and low power consumption are described. A search is initially performed to obtain a set of multipaths for a transmission from at least one base station. At least one multipath (e.g., the minimum number of multipaths) having a combined performance metric (e.g., a combined SNR) exceeding a threshold is identified. The at least one multipath is assigned to, and processed by, at least one finger processor to recover the transmission from the base station(s).

摘要： Embodiments disclosed herein address the need in the art for an efficient multi-symbol deinterleaver. In one aspect, a plurality of memory banks are deployed to receive and simultaneously store a plurality of values, such as soft decision values determined from a modulation constellation, in accordance with a storing pattern. In another aspect, the storing pattern comprises a plurality of cycles, a selected subset of the plurality of memory banks and an address offset for use in determining the address for storing into the respective memory banks indicated for each cycle. In yet another aspect, the stored values may be accessed in order with a sequentially increasing index, such as an address. Various other aspects are also presented. These aspects have the benefit of allowing multiple symbol values to be deinterleaved in an efficient manner, thus meeting computation time constraints, and conserving power.

摘要： Methods, systems, and devices for wireless communication are described. A user equipment (UE) utilizing enhanced carrier aggregation (eCA) may identify a limit to the number of channel state feedback (CSF) processes it is capable of supporting. The UE may transmit an indication of this limit to a base station, which may configure the UE for channel state reporting, and send channel state reporting triggers according to the indicated limit. The UE's determination of the limit to the number of CSF processes may be based on various transmit or receive antenna configurations. A single trigger may correspond to reports covering multiple subframes and/or component carriers. The base station may also arrange the channel state reporting configuration to reduce the peak number of channel state reports that the UE processes during each subframe. The UE may also determine that a number of channel state processes needed to support channel state reporting in a subframe exceeds its capacity. The UE may then prioritize the channel state processes and/or may transmit one or more non-current reports.
摘要翻译：描述了用于无线通信的方法，系统和设备。利用增强的载波聚合（eCA）的用户设备（UE）可以识别其能够支持的信道状态反馈（CSF）过程的数量的限制。 UE可以向基站发送该限制的指示，该基站可以将UE配置为信道状态报告，并根据指示的限制发送信道状态报告触发。 UE对CSF过程数量的限制的确定可以基于各种发射或接收天线配置。单个触发器可以对应于覆盖多个子帧和/或分量载波的报告。基站还可以布置信道状态报告配置以减少在每个子帧期间UE处理的信道状态报告的峰值数量。 UE还可以确定在子帧中支持信道状态报告所需的信道状态过程的数量超过其容量。然后，UE可以优先化信道状态过程和/或可以发送一个或多个非当前报告。

摘要： An HDLC accelerator includes a deframer and framer to respectively accelerate the deframing and framing processes for PPP packets. The deframer includes an input interface unit, a detection unit, a conversion unit, and an output interface unit. The input interface unit receives a packet of data to be deframed. The detection unit evaluates each data byte to detect for special bytes (e.g., flag, escape, and invalid bytes). The conversion unit deframes the received data by removing flag and escape bytes, "un-escaping" the data byte following each escape byte, providing a header word for each flag byte, and checking each deframed packet based on a frame check sequence (FCS) value associated with the packet. The output interface unit provides deframed data and may further perform byte alignment in providing the deframed data. A state control unit provides control signals indicative of specific tasks to be performed for deframing.

摘要： A wireless communication signal in Long Term Evolution (LTE) may be interleaved in a manner which permits a partitioning of a received inter-column bit- reversed interleaved code block for improved de-interleaving. The code block may be divided into equal subportions which may be simultaneously de-interleaved both forward and backward, and in parallel with other subportions. An even number of subportions may be provided. Dividing a received code block in this manner may improve de-interleaving performance.

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 Nlog2(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传统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Nlog2（N）个乘法。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。
