摘要： Supporting communication on multiple carriers. A user equipment (UE) is configured with a base (anchor, regular, stand-alone) carrier and a dependent (extension) carrier linked (paired) 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 (714) 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 (718), 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. A configuration of the base (anchor) carrier and a dependent (extension) carrier is received from the eNodeB at the UE.

摘要： In a wireless network (100) with HSDPA-enabled user equipment devices (130), the base transceiver station (120) transmits to each HSDPA-enabled UE information regarding allocation of HSDPA codes and associated modulation techniques for other HSDPA-enabled UEs. Using this additional control information, each UE configures decision feedback filter of its equalizer to reduce inter-user interference. The additional control information may be transmitted in a packet (300) that includes a CRC portion (310) with the packet's CRC masked by a common ID, which is known to the HSDPA-enabled UEs. To reduce the number of bits needed to transmit the additional control information, the HSDPA codes used with a particular modulation technique are allocated consecutively. For each modulation technique, only the beginning code and the total number of codes need be known to the UEs. The number of codes used with each modulation technique may be allowed to change once in several TTIs.

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： 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。

摘要： Providing for mixed single carrier and multi-carrier uplink transmission in a wireless communication environment is described herein. By way of example, a network is provided that can identify uplink capabilities or restrictions of respective devices of a mixed population of mobile devices, and schedule single carrier or multi-carrier transmissions accordingly. In some aspects, different subsets of multi-carrier transmission can be given priority over other subsets. Based on the priority, the network can schedule/modify relative transmit powers for respective subsets, accommodate power constraints of higher level networking protocols, and optionally give priority to one or more of the distinct transmissions. In addition, priority can be given to respective subsets of the multi-carrier transmission, to ensure high quality or reliability for important transmissions. Thus, provided is an integrated network that accommodates a powerful mix of single carrier and multi-carrier services for a mixed population of mobile devices.

摘要： A communication system incorporates a multiplexing scheme so that a base node that schedules user equipment (UE) can determine whether an ACK/NACK and/or a service request (SR) has been received when both uplink (UL) transmissions are simultaneously scheduled. Significant complexity reduction, better link efficiency, and higher multiplexing capability since the base node can interpret selective use by the UE of either the ACK/NACK or SR UL channel. Such interpretation can be extended to when multiple downlink (DL) transmission modes can be used, specifically DL single input multiple output (SIMO), DL multiple input multiple output (MIMO) with rank 1 transmission, and DL MIMO with rank 2 transmission. Based upon knowledge of the scheduling and DL transmission mode, the base node does not have to blind decode a number of possibilities due to the mapping of possible responses from the UE. In addition, the multiplexing scheme is applicable to FDD and TDD.
摘要翻译：通信系统包括复用方案，使得调度用户设备（UE）的基站节点可以确定当同时调度上行链路（UL）传输时是否已经接收到ACK / NACK和/或服务请求（SR）。显着的复杂度降低，更好的链路效率和更高的复用能力，因为基站节点可以解释UE对ACK / NACK或SR UL信道的选择性使用。这样的解释可以扩展到当可以使用多个下行链路（DL）传输模式时，具体来说具有等级1传输的DL单输入多输出（SIMO），DL多输入多输出（MIMO）和具有秩2传输的DL MIMO。基于调度和DL传输模式的知识，由于来自UE的可能响应的映射，基本节点不必对许多可能性进行盲解码。另外，复用方案适用于FDD和TDD。

摘要： Systems and methodologies are described that facilitate signaling and detecting discontinuous transmission (DTX) in a wireless communication environment. A DTX indicator and Channel Quality Indicator (CQI) feedback can be multiplexed within a common uplink control channel subframe and transmitted to a base station when the access terminal is operating in DTX mode for an Acknowledgement Channel. Further, when operating in non-DTX mode, the access terminal can multiplex an ACK indicator or a NAK indicator with the CQI feedback within a common uplink control channel subframe, which can thereafter be transferred to the base station. Accordingly, the base station can detect DTX operation or non-DTX operation of the access terminal. For example, reference signal symbols can carry one of the DTX indicator, the ACK indicator, or the NAK indicator. Pursuant to another example, the CQI feedback and the DTX indicator can be combined and carried jointly by non-reference signal symbols.
