摘要： A receiver operates in a mobile communication system that comprises first node and second nodes, the first and second nodes transmitting common control signals and dedicated data signals, respectively. The receiver determines a first timing rotation and/or a first frequency rotation of the common control signals and a second timing rotation and/or a second frequency rotation of the dedicated data signals. The receiver determines a first and/or second difference, wherein the first difference is a difference between the first timing rotation of the common control signals and the second timing rotation of the dedicated data signals and the second difference is a difference between the first frequency rotation of the common control signals and the second frequency rotation of the dedicated data signals. An adapted timing of dedicated data signals is produced based on the first and/or second differences, and the adapted timing is used to receive dedicated data signals.

摘要： A frequency error of received signals in an OFDM receiver of a wireless communications system is determined. Symbols of a given duration are transmitted as cells on sub-carrier frequencies; and some of the cells are pilot cells modulated with reference information. The method comprises the steps of selecting at least three pilot cells (p0, p1, p2) from different symbols and different sub-carriers; determining the symbol and the sub-carrier on which each pilot cell is transmitted; determining for each pilot cell a phase difference between received and generated signals; calculating therefrom a change in phase difference (Φx) caused by the frequency error; and calculating the frequency error from the calculated change in phase difference (Φx). In this way a receiver capable of determining a frequency error also in situations where only a short data burst, such as a single resource block, is available for the estimation is provided.

摘要： According to the teachings presented herein, a method and apparatus provide a reduced search space for blindly decoding a message included in a signal received at a communication receiver, where the message has an unknown format. Improving blind detection efficiency in this manner offers numerous advantages, including but not limited to lower power consumption through reduced processing overhead, and lower power consumption through expanded sleep opportunities. As a non-limiting example, the communication receiver comprises a mobile station configured for operation according to Long Term Evolution (LTE) standards, as promulgated by the 3GPP for E-UTRA systems, where the mobile station is configured to reduce a search space of DCI message decoding by determining message format likelihoods and blindly decoding a received DCI message based on the message format likelihoods.

摘要： Decoding a received Orthogonal Frequency Division Multiplex (OFDM) signal that occupies a first set of subcarriers in a radio frequency spectrum includes ascertaining an interference model that represents interference occurring in the first set of subcarriers caused by a transmitted OFDM signal that occupies a second set of subcarriers in the radio frequency spectrum. A set of scaled soft values is produced that represents information conveyed by the received OFDM signal over the first set of subcarriers, wherein each scaled soft value in the set of scaled soft values corresponds to a respective one of the subcarriers in the first set of subcarriers, and wherein a scaling amount applied to each of the scaled soft values is based on a corresponding level of interference in said respective one of the subcarriers as indicated by the interference model. A decoding process is performed that generates detected data from the scaled soft values.

摘要： A wireless communication system receiver receives and processes a signal comprising at least two component carriers carrying data scheduled to the receiver and having center frequencies spaced apart by at least one component carrier frequency difference. Each component carrier comprises a number of subcarriers spaced apart by a system subcarrier frequency spacing. A common divisor is obtained for the at least one component carrier frequency difference and the system subcarrier frequency spacing. A symbol is received on the subcarriers of the component carriers and downconverted to baseband to produce a baseband symbol. A block of padding values is inserted in the baseband symbol to produce a padded symbol. The length of the block of padding values is such that intermediate subcarriers are inserted to yield a subcarrier frequency spacing for the padded symbol equal to the common divisor. Finally the padded symbol is Fast Fourier Transform, FFT, processed.

摘要： In a system using spatial precoding, in the event that reliable channel state information is unavailable, a transmitting node uses an extended transmission mode, in which the precoders applied to data within each of several groups of time-frequency resources vary according to frequency. The extended transmission mode creates a frequency-selective variation in precoders, which may appear to be random, while using DMRS-based transmission. This variation is achieved by applying different precoders to the resource elements carrying data, using a pattern of precoder variation that is known to the receiving device. The precoding applied to DMRS within a given group of time-frequency resources is held constant—thus, the varying precoders within a given group of time-frequency resources are only applied to data elements, not to the DMRS resource elements.
摘要翻译：在使用空间预编码的系统中，在可靠的信道状态信息不可用的情况下，发送节点使用扩展传输模式，其中应用于几组时频资源中的每一组中的数据的预编码器根据频率而变化。在使用基于DMRS的传输时，扩展传输模式在预编码器中产生频率选择性变化，其可能看起来是随机的。通过使用接收设备已知的预编码器变化的模式，将不同的预编码器应用于携带数据的资源元件来实现。在给定的一组时间 - 频率资源内的DMRS应用的预编码保持不变，因此，给定的一组时间 - 频率资源内的变化的预编码器仅被应用于数据元素而不是DMRS资源元素。
