摘要： Techniques for supporting multi-frequency range signal processing for a wireless device. In an aspect, a first antenna is provided to support first and third frequency ranges. A second antenna is separately provided to support two separate ranges that are each intermediate in frequency between the first and third frequency ranges. In an aspect, the two separate ranges may correspond to, e.g., a GPS range and a 1500-MHz band. To separate the two ranges of the second antenna, one or more low-pass and/or band-pass filters may be provided. In other aspects, a third antenna may be added to support a fourth frequency range higher than the third frequency range. Other frequency range combinations, dual antenna aspects, and carrier aggregation features are further disclosed herein.

摘要： Techniques for determining power relaxation values are disclosed. The power relaxation values may be determined according to an ending; resource block (RB) and a number of RBs in a contiguous allocation. In one aspect, the power relaxation values are arranged into regions based, at least in part, on transmission channel bandwidths and the distance from a protected adjacent channel. A user equipment (UE) can determine a power relaxation value for its current allocation using the ending RB index and contiguous RB length and can adjust its transmission power accordingly. Evolved NodeBs may estimate the power relaxation that a particular UE has selected in order to more accurately determine the transmit power available to the UE. Using the more accurate estimate of transmit power, the eNB may schedule the UE for uplink transmissions accordingly.

摘要： Techniques for optimizing the power consumption of existing low cost multi-gain state power amplifiers (PA) to increase the talk time of wireless communication devices are described. In an exemplary embodiment a device, such as a baseband processor, operates to set a multistage PA having at least two gain states for amplifying a transmit signal to a lowest power consuming gain state. The device calculates a transition power level as a function of an identified maximum power reduction (MPR) value and switches the PA to a higher gain state from a lower gain state when a transmission power level is higher than the calculated transition power level.

摘要： Methods, systems, and devices for wireless communication are described. A user equipment (UE) may mitigate self-interference and intermodulation products caused by communicating over two carriers in order to improve measurements of a third carrier. The UE may determine a measurement configuration to determine the quality of the third carrier. The measurement configuration may include identifying time periods with no scheduled uplink transmissions, time periods with a transmit power below a power threshold, time periods with frequency locations with an expected lower intermodulation interference, or time periods with a scheduled reference signal transmission (e.g., a synchronization signal (SS) block). The UE may also reduce a transmit power for a time period or drop a scheduled uplink transmission in order to perform more accurate measurements on the third carrier. In some cases, a base station may schedule a measurement gap for the UE to perform the measurements.

摘要： Low complexity, high order multiple input, multiple output (MIMO) operations are described in which a user equipment (UE), configured with at least one normal performance receiver chain and at least one low-performance, low-complexity diversity receiver chain, signals a capabilities indicator identifying existence of the low-performance diversity receivers. Using the UEs capabilities, a serving base station may schedule uplink and downlink transmissions for the UE to reduce uplink-downlink collisions below a minimum threshold number. The serving base station may also take UE transmit power into consideration for signaling power control or modulation and coding schemes in order to minimize potential interference cause by UE transmissions. For channel state feedback, the UE may provide different channel feedback for uplink-downlink collision subframes and non-collision subframes.

摘要： A transmitter includes a delta-sigma modulator (100) characterized by a noise transfer function having a multitude of zeroes positioned substantially near a frequency band of a receive signal. The transmitter further includes, in part, a multi-phase digital-to-analog converter, DAC (200), converting an output signal of the delta- sigma modulator to an analog signal. The DAC is characterized by a transfer function that passes the desired signal to its output and attenuates a multitude of images of the sampling clock signal. The transmitter transmits at a frequency defined by an odd multiple of a fraction of the sampling clock signal frequency. The DAC includes a number of stages each pair of which is associated with one of the images being attenuated. The delta-sigma modulator includes a multitude of stages each associated with a different one of the zeroes. Each stage of said delta-sigma modulator optionally receives three tap coefficients.
