摘要： Embodiments disclosed herein address the need in the art for an extended acknowledgment/rate control channel. In one aspect, an acknowledgment command and a rate control command are combined to form a combined command. In another aspect, the combined command is generated in accordance with a constellation of points, each point corresponding to a pair consisting of a rate control command and an acknowledgment command. In yet another aspect, the points of the constellation are designed to provide the desired probability of error for the respective command pairs. In yet another aspect, a common rate control command is transmitted along with a combined or dedicated rate control command. Various other aspects are also presented. These aspects have the benefit of reduced overhead while providing acknowledgment and rate control to single remote stations and/or groups of remote stations.

摘要： Techniques are provided for the suppression of reference signal transmissions to enable sensing in cognitive radio communications. In one example, there is provided a method, operable by a network entity (e.g., evolved Node B), that may involve communicating with another network entity to determine parameters of a quiet period, the parameters comprising at least one of when the quiet period occurs and duration of the quiet period. The method may involve transmitting a reference signal in a first channel exclusively during a first plurality of subframes of a first frame period, wherein the first frame period further includes a quiet period during which no signals are transmitted, and performing during the quiet period a sensing operation with respect to the first channel.

摘要： Techniques for supporting communication on multiple carriers are disclosed. In one design, a user equipment (UE) is configured with a base carrier and a dependent carrier linked to the base carrier. Data transmission on the dependent carrier is scheduled via a scheduling carrier, which is different from the dependent carrier. The UE receives a scheduling grant on the scheduling carrier and determines whether the scheduling grant is for the base carrier and/or the dependent carrier. The UE communicates (e.g., sends or receives data) on the base carrier and/or the dependent carrier based on the scheduling grant. The scheduling grant may be (i) a separate grant carrying scheduling information for only one carrier, (ii) a common grant carrying scheduling information for both carriers, (iii) a joint grant carrying separate scheduling information for each carrier, or (iv) a composite grant that may be a separate grant, a common grant, or a joint grant.

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： Techniques for transmitting data in a manner to facilitate equalization at a receiver are described. Guard intervals are appended to data blocks such that each data block has a guard interval at the beginning of the data block and a guard interval at the end of the data block. Each guard interval may be discontinuous transmission (DTX), a polyphase sequence, or some other known sequence. Pilot is appended to each set of at least one data block. The data blocks, pilot, and guard intervals may be sent using various slot structures and are processed for transmission. The processing may include mapping the data blocks to at least one physical channel, channelizing the data blocks for each physical channel with a channelization code, combining all physical channels, and scrambling the combined data, pilot, and guard intervals with a scrambling code.

摘要： The contents of a counter at a remote station is used to select a Walsh cover, which is used to cover the acknowledgment or negative acknowledgment bits sent on a new reverse acknowledgment channel (R-ACKCH). In the new reverse acknowledgment channel, the value of the acknowledgment bits for the broadcast transmissions is used to select the Walsh code sequence that covers the acknowledgment bit for the dedicated transmissions. When a base station receives an acknowledgment message from the remote station, the base station checks the Walsh cover of the message and extracts the embedded counter content. If the embedded counter content of the received acknowledgment or negative acknowledgment differs from the local counter value, the base station determines that a synchronization problem occurred, such that the remote station is not operating with the current transmission format information. Hence, the counter values act as the sequence identifiers of the Walsh masks.
摘要翻译：远程站的计数器的内容用于选择一个沃尔什覆盖，用于覆盖在新的反向确认通道（R-ACKCH）上发送的确认或否定确认位。在新的反向确认信道中，用于广播传输的确认位的值用于选择覆盖专用传输的确认位的沃尔什码序列。当基站从远程站接收到确认消息时，基站检查消息的沃尔什覆盖并提取嵌入的计数器内容。如果接收到的确认或否定确认的嵌入计数器内容与本地计数器值不同，则基站确定发生同步问题，使得远程站未以当前传输格式信息进行操作。因此，计数器值用作沃尔什掩模的序列标识符。
