摘要： According to one aspect, the present invention advantageously provides a method and apparatus that increase communications throughput by manipulating the order or manner in which CQI values are reported in a multi-rank CQI report that constrains one or more such values according to reporting order. As a non-limiting example, the present invention provides that the reporting order used for reporting multiple CQI values is chosen to eliminate or at least reduce under-reporting and over-reporting errors arising from the use of differential reporting formats for one or more of the reported CQI values. Additionally, the present invention provides for selection between single-rank or multi-rank CQI reporting, based on determining which one corresponds to the highest channel capacity, in view of the differential reporting constraints.

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： 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： In a heterogeneous network, low power cells are detected by correlating a first and second signal originating from an unknown cell, such as synchronization signals, e.g., SSS received in a first and second time period (e.g., subframes 0 and of a frame with corresponding sets of possible SSS signals. The cell identities for the candidate cells can be used to determine corresponding reference symbol sequences for the candidate cells. The final determination of the cell identity is then made by correlating a third signal originating from the unknown cell, such as a reference signal received in a third time period (e.g., an almost blank subframe or a broadcastsubframe)with the set of reference signalsfor the candidate cells. The correct cell identity is determined to be the cell identity yielding the greatest correlation with its corresponding reference signal.

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 pre-coding matrix is determined in an OFDMA, multiple transmit antenna communication system having a number of sub-carriers grouped into a number, M , of resource blocks. This involves determining a frequency selectivity of a channel through which received signals have propagated. A number N of selected resource blocks is then determined as a function of the frequency selectivity the N selected resource blocks being those for which pre-coding matrices will be determined, wherein N . The pre-coding matrices are then determined for the N selected resource blocks. Pre-coding matrices for a remaining M-N of the M resource blocks are determined by means of interpolation applied to the N pre-coding matrices determined for the N selected resource blocks.

摘要： An Orthogonal Frequency Division Multiplexing (OFDM) symbol for transmission from a non-reference transceiver to a user equipment (UE) in a mobile communication system is generated by ascertaining a general timing for transmission of OFDM symbols, wherein the general timing is associated with a reference transceiver. A UE timing relative to the general timing is ascertained. An initial resource element (RE) value is adjusted by a pre-compensating amount to obtain a pre-compensated RE value, wherein the pre-compensating amount is based on the UE timing relative to the general timing. The pre-compensated resource element value is supplied as one of a plurality of values to be transmitted. An IFFT is performed on the plurality of values to be transmitted to obtain pre-compensated initial signal information. A cyclic prefix is appended to the pre-compensated initial signal information to form an OFDM symbol for transmission from the non-reference transceiver to the UE.

摘要： A transmitted OFDM signal is detected in a receiver of a wireless communication system. The receiver has at least two receiver branches, each comprising an antenna, a front end receiver, a Discrete Fourier Transform unit, and a channel estimator. The receiver further comprises a detector for detecting received data symbols. The method comprises the steps of determining (101) a system bandwidth associated with the transmitted signal; comparing (102) the determined system bandwidth with a predetermined value; determining (103), if the system bandwidth is lower than the predetermined value, channel estimates separately for each branch, and detecting (104) received data symbols from the received signals and corresponding channel estimates; and calculating (105), if the system bandwidth is higher than the predetermined value, a weighted sum of signals from each branch, determining (106) a combined channel estimate, and detecting (107) received data symbols from the weighted sum and the combined channel estimate.
