摘要： Techniques for performing decision feedback equalization are described. A feed-forward filter response and a feedback filter response are derived based on a channel estimate and a reliability parameter and further without constraint on the feedback filter response or with a constraint of no feedback for an on-time sample. The reliability parameter is indicative of the reliability of the feedback used for equalization and may be frequency dependent or frequency invariant. Different feed-forward and feedback filter responses may be derived with different constraints on the feedback filter and different assumptions for the reliability parameter. Equalization is performed with the feed-forward and feedback filter responses. If equalization is performed for multiple iterations then, for each iteration, the reliability parameter may be updated, the feed-forward and feedback filter responses may be derived based on the updated reliability parameter, and equalization may be performed with the filter responses for the iteration.

摘要： An equalization filter is provided with the ability to softly switch between pure linear equalization and decision feedback equalization. A reliability gain factor and an associated gain factor calculated by a predetermined mapping relation are provided in a decision feedback path and a feedforward path, respectively. Increasing the reliability gain factor increases the significance of the decision feedback filtering. Better performance than pure linear equalization and pure decision feedback equalization can be achieved.

摘要： Techniques for transmitting information using cyclically shifted sequences are described. In one design, first and second sequences may be generated by cyclically shifting a base sequence by first and second amounts, respectively. The base sequence may be a CAZAC sequence, a PN sequence, or some other sequence having good correlation properties. The cyclic shifts for the first and second sequences may be determined based on a hopping pattern. A first modulated sequence may be generated based on the first sequence and a first modulation symbol and may be sent in a first time interval. A second modulated sequence may be generated based on the second sequence and a second modulation symbol and may be sent in a second time interval. Each modulated sequence may be sent on K consecutive subcarriers using localized frequency division multiplexing (LFDM)

摘要： Techniques for transmitting acknowledgement (ACK) information in a wireless communication system are described. The system supports data transmission to multiple user equipments (UEs) on the same downlink resources with spatial division multiple access (SDMA). A base station sends a data transmission with multiple (M) layers to M UEs. The downlink resources used for the data transmission are associated with ACK resources used to send ACK information for the data transmission. The ACK resources may be partitioned into M portions, e.g., based on frequency division multiplexing (FDM). Each of the M layers is associated with a respective portion of the ACK resources. A recipient UE for each layer sends ACK for that layer on the associated portion of the ACK resources. For each ACK resource portion, one or more pilot symbols may be sent on one or more resource elements, and ACK symbols may be sent on remaining resource elements.

摘要： Facilitating frequency hopping for single carrier, frequency division multiple access (SC-FDMA) transmission is described herein. By way of example, user data transmitted within a transmission allocation unit can be frequency shifted with respect to time based slots of the allocation unit. As a result, frequency hopping can be accomplished while preserving single carrier constraints and a low peak to average power ratio (PAPR). Furthermore, various frequency shifted mechanisms are disclosed to accomplish preservation of single carrier restraints. For example, a scheduler can select between cyclic frequency shifting, transposed frequency shifting, and multiplexing of frequency selective scheduled and frequency hopped data based on an audit of scheduled data for the transmission allocation unit. As a result, the reduction in interference achieved through frequency hopping can be combined with the low PAPR for various data allocation configurations.
摘要翻译：本文描述了用于单载波频分多址（SC-FDMA）传输的促进跳频。作为示例，在传输分配单元内传输的用户数据可以相对于分配单元的基于时间的时隙进行频移。结果，可以在保持单载波约束和低峰均功率比（PAPR）的同时完成跳频。此外，公开了各种频移机构来完成单载波约束的保存。例如，调度器可以基于对传输分配单元的调度数据的审计在循环频移，转置频移和频率选择性调度和跳频数据的复用之间进行选择。因此，通过跳频实现的干扰减少可以与用于各种数据分配配置的低PAPR相结合。

摘要： Techniques for performing spectral shaping to achieve a desired peak-to- average ratio (PAR) are described. Spectral shaping may be selectively performed for a single-carrier frequency division multiplexing (SC-FDM) signal based on one or more criteria, e.g., in transmit power limited conditions and/or if a modulation scheme with lower PAR is unavailable. At least one parameter of a window function or spectral shaping filter may also be adjusted based on at least one characteristic of the SC-FDM signal. For example, the roll-off of the spectral shaping filter may be adjusted based on the modulation scheme and/or the number of subcarriers used for the SC-FDM signal. A transmitter may perform spectral shaping on modulation symbols, if enabled, to obtain spectrally shaped symbols. Spectral shaping may be performed in the frequency domain either within an allocated bandwidth or with bandwidth expansion. The SC- FDM signal may be generated based on the spectrally shaped symbols.
