摘要： A mobile device comprises a receiver unit that has at least two receivers to implement multi-antenna receive diversity. A control unit estimates, at the mobile, an amount of utilization by a traffic channel of the mobile of total transmission power capacity at a base station. The mobile applies multi-antenna receive diversity in the mobile device based on the power capacity utilization. The mobile estimates an amount of power a network is transmitting to the mobile relative to a pilot reference. Other indicators are based on quality of the traffic channel between the mobile and the network, capacity limiting resources, a number of sectors in a soft hand-off in a wireless system, etc. The indicators are used to control application of multi-antenna receive diversity in a mobile device.

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 MxN 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 ((MxN)+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MxN 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在预定的延迟。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，增益由所做的功率测量（（MxN）+1）任务决定。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）收敛用于下行链路子帧的适当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： Disclosed are apparatus and methods for dynamic data-based scaling of data. The disclosed methods and apparatus involve storing one or more input data samples (504), which are to be scaled (518) and input to a processing function such as a Fast Fourier Transform (506). A scaling value operable for scaling the one or more data samples is determined (516) based on the one or more input data samples, and then the stored data samples are scaled based on the computed scaling value when read out of storage prior to the processing function. The scaling of data based on the input data allows the data to be scaled dynamically, not statically, and ensures that the data fits within a desired bit width constraint of the processing function.

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： A method of wireless communication at a user equipment (UE) is presented. The UE may include one or more antennas which are shared between a first network connection and a second network connection in a dual connectivity mode. The method includes reporting a first sounding reference signal (SRS) antenna-switching capability to a base station. The method also includes transmitting an SRS to the base station via a second SRS antenna-switching capability when the first network connection has priority over the second network connection, where the second SRS antenna-switching capability is reduced with respect to the first SRS antenna-switching capability.
