摘要： Systems and methodologies are described that facilitate sending and/or receiving user equipment specific reference signals (UE-RSs) in a wireless communication environment. A UE-RS pattern can be selected, yielded, etc. based upon a number of symbols from a subframe utilized for downlink transmission. At least one time domain component of the UE-RS pattern can vary based upon the number of symbols from the subframe utilized for the downlink transmission. For instance, the at least one time domain component can be punctured, time-shifted, and so forth. Further, UE-RSs can be mapped to resource elements of the subframe as a function of the UE-RS pattern. Moreover, a UE can utilize the UE-RS pattern to detect UE-RSs on the resource elements of the subframe. Further, the UE can estimate a channel based upon the UE-RSs.

摘要： Techniques for performing interference cancellation in a wireless (e.g., CDMA) communication system are described. In one aspect, per-bin power estimates for multiple orthogonal bins are derived by estimating at least two components of these power estimates. The components may include, e.g., channel gain, noise and interference, and bin gain. Interference cancellation is performed based on the per-bin power estimates. In another aspect, interference cancellation is performed in multiple stages with fast tracking. A total power estimate and per-bin power estimates are derived for a first stage. A total power estimate is derived for a second stage. Per-bin power estimates are also derived for the second stage based on the total power estimates for the first and second stages and the per-bin power estimates for the first stage. Interference cancellation is performed for each stage based on the per-bin power estimates for that stage.

摘要： Disclosed are methods and apparatus for sampling rate conversion in a wireless transceiver. The methods and apparatus achieve agile setting of sampling rates or resampling by adaptively setting a sampling rate of a signal based on at least one performance requirement of the transceiver. In particular, the methods and apparatus perform sampling of an input signal at a first sampling rate to gain one or more input signal samples. The input signal samples are then filtered using parallel or polyphase filtering operating at a second sampling rate lower than the first sampling rate. The filtered samples are then interpolated at the second sampling rate to achieve resampling of the input signal. Polyphase filtering affords an effectively high input sampling rate for good spectrum image rejection, while allowing the second sampling rate to be effectively much lower than the first rate, thereby reducing the complexity of multiplier operations for interpolation.

摘要： In embodiments, user equipment (UE) is configured to acquire automatic gain control (AGC) of an analog RF front end by maintaining a plurality of M×N AGC loops in which the output of the power detector drives input of a gain state machine after a predetermined delay. Each of the loops corresponds to a different periodic set of tasks of (1/M) subframe in length. In each of the loops, the gain is determined by a power measurement taken ((M×N)+1) tasks ago. A synchronization signal, such as a Primary Synchronization Signal, occurs early in Time Division Duplex (TDD) subframes that follow selected downlink subframes. The periodicity of the selected subframes is N. This allows the UE to converge on proper AGC gain for downlink subframes through a relatively short search, such as a binary search. The UE can then decode the synchronization signal and acquire network timing.
摘要翻译：在实施例中，用户设备（UE）被配置为通过维持多个M×N个AGC环路来获取模拟RF前端的自动增益控制（AGC），其中功率检测器的输出驱动增益状态机的输入驱动增益状态机的输入，预定的延迟。每个循环对应于长度为（1 / M）子帧的不同周期性任务集合。在每个循环中，增益由以前进行的功率测量（（M×N）+1）任务确定。诸如主同步信号的同步信号早于在选择的下行链路子帧之后的时分双工（TDD）子帧中。所选择的子帧的周期为N.这允许UE通过相对较短的搜索（例如二进制搜索）收敛于针对下行链路子帧的适当的AGC增益。然后，UE可以对同步信号进行解码并获取网络定时。

摘要： Techniques for performing interference cancellation in a wireless (e.g., CDMA) communication system are described. For a single-sector interference canceller, received samples are processed (e.g., despread) to isolate a signal from a transmitter (e.g., a base station) and obtain input samples. The input samples are transformed based on a first transform (e.g., a fast Hadamard transform) to obtain received symbols for multiple orthogonal channels (e.g., Walsh bins). The received symbols for the multiple orthogonal channels are scaled with multiple gains to obtain scaled symbols. The gains may be related to the inverses of the power estimates for the orthogonal channels. The scaled symbols are transformed based on a second transform (e.g., an inverse fast Hadamard transform) to obtain output samples, which are processed (e.g., spread) to obtain interference-canceled samples having the signal from the transmitter suppressed.
