Abstract: Techniques for controlling receive diversity on a wireless device are disclosed. One or more thresholds may be determined based on one or more parameters which may be compared against the one or more thresholds to determine whether to enable or disable receive diversity. For example, a wireless device may determine a threshold value based on a first parameter related to communication of the wireless device. The wireless device may decide to enable or disable receive diversity based on a second parameter and the threshold value. The wireless device may receive data transmission with receive diversity when a decision is made to enable receive diversity. The first parameter may relate to characteristics of data being received by the wireless device and may be represented by percentage downlink utilization. The second parameter may relate to channel conditions and may be represented by an improvement in received signal quality with receive diversity enabled.

Abstract: In general, this disclosure describes techniques for demodulating wireless signals. In particular, the techniques of this disclosure dynamically select between two or more demodulators based on channel quality information measured over a plurality of measurement periods. For example, a wireless communication device (WCD) may switch from a first demodulator to a second demodulator when the channel quality information associated with the demodulators indicates a better channel quality for the second demodulator than the first demodulator for a consecutive number of measurement periods. As another example, the WCD may compute, for each measurement period, the difference between the channel quality information associated with each of the demodulators, sum the differences, and switch demodulators when the total accumulation of the differences exceeds a threshold.

Abstract: An apparatus, system, and method efficiently manage transmission power in a user equipment (UE) device by maintaining and applying an authorized power level to determine a transmission power level after a power limited transmission and before a new power control command has been received. The UE device maintains the authorized power level by monitoring and adjusting the authorized power level based on received power control commands. After a power limited transmission where the maximum power level is less than the authorized power level, the UE device determines the transmission power level for the next transmission based on the authorized power level. Accordingly, after the power limiting situation has ceased, the UE device transmits at the optimum power level eliminating the inefficiencies of transmitting at a lower than authorized power before the next power control command is received.

Abstract: Techniques for controlling transmit power for a data transmission sent on multiple data channels, which may be intermittently active, are described. Each data channel is monitored for activity (e.g., based on an error correction code, received signaling information, received block energy, and so on) and deemed to be dormant or not dormant (e.g., based on the amount of elapsed time since activity was last detected on the data channel). A signal quality (SIR) target may be maintained for each non-dormant data channel and updated based on the status of received data blocks for the data channel. A final SIR target, used for power control of the data transmission, may be set to the highest SIR target among the SIR targets for the non-dormant data channels. The final SIR target may also be updated directly based on the status of received data blocks for the non-dormant data channels.

Abstract: An apparatus for coarse compensation of a direct current (DC) offset in a direct to baseband receiver architecture utilizes a serial analog to digital converter (ADC), such as a Delta-Sigma converter, to convert the received signal to digital form. The output of the ADC is sampled for a predetermined number of samples and a counter coupled to the ADC is incremented each time the sample generated by the ADC is a logic one. The counter is not incremented if the sample from the ADC is a logic zero. After the predetermined number of samples is obtained, the counter value is indicative of the DC offset in the received signal. The counter value may be converted by a code converter to a correction value for easy operation of a digital to analog converter (DAC). If the number of samples from the ADC is a power of two, the code converted may be readily implemented by simply inverting the most significant bit (MSB) from the counter to thereby generate a twos complement version of the counter value. The correction value is coupled to the DAC to generate a compensation signal, which is provided to the received signal path in the form of a feedback signal to compensate for the DC offset.

Abstract translation: 直接到基带接收器架构中用于粗略补偿直流（DC）偏移的装置利用诸如Delta-Sigma转换器的串行模数转换器（ADC）将接收到的信号转换为数字形式。 ADC的输出对预定数量的采样进行采样，并且每当ADC产生的采样为逻辑1时，耦合到ADC的计数器递增。 如果来自ADC的采样是逻辑0，则计数器不会递增。 在获得预定数量的样本之后，计数器值指示接收信号中的DC偏移。 计数器值可由代码转换器转换为校正值，以便于数字模拟转换器（DAC）的操作。 如果来自ADC的采样数是2的幂，则转换的代码可以通过简单地反转来自计数器的最高有效位（MSB）来实现，从而生成计数器值的二进制补码版本。 校正值耦合到DAC以产生补偿信号，该补偿信号以反馈信号的形式提供给接收信号路径以补偿DC偏移。
