Abstract: In a communication system, user equipment (UE) conditionally performs uplink transmit diversity (ULTD) either by Switched Antenna Transmit Diversity (SATD) or Beamforming Transmit Diversity (BFTD) using a first antenna and a second antenna. Either a serving node or the UE determines that uplink transmit diversity is conditionally authorized. Either a serving node or the UE measures a value. The UE transmits using ULTD in response to determining that an enabling condition based on the value is satisfied. The UE can also disable uplink transmit diversity in response to determining that a disabling condition based on the value is satisfied. The disabling condition comprises a disabling threshold that equals the enabling condition comprising an enabling threshold with a threshold adjustment for hysteresis.

Abstract: Techniques for identifying and suppressing frequency spurs in a signal are disclosed. In an embodiment, an incoming signal is rotated by a frequency related to a spur frequency, and an estimate of the content of the rotated signal is derived. The estimate may be subtracted from the rotated incoming signal, and the result de-rotated by the spur frequency. In an embodiment, the incoming signal may be rotated such that the spur is centered at DC. In an alternative embodiment, the estimate may be de-rotated before being subtracted from the original incoming signal. Techniques for addressing multiple spurs using serial and parallel architectures are disclosed. Further disclosed are techniques for searching for the presence of spurs in an incoming signal, and tracking spur frequencies over time.

Abstract: Systems and methods for temperature-calibration of an uncompensated XO in a mobile device during mobile device operation. The XO is temperature-calibrated based on assistance from wireless signals, such as from satellite source, and optionally from terrestrial sources such as WWAN, CDMA, etc. Based on one or more received wireless signals received at a receiver, corresponding frequency estimates of the XO are obtained and correlated with corresponding operating temperatures in a processor. Based on one or more samples of frequency estimates and associated temperatures, the XO is temperature-calibrated in the processor wherein a frequency-temperature (FT) model is formulated for the XO. The frequency of the temperature-calibrated XO can be determined from the FT model at any given temperature.

Abstract: Wireless devices and techniques providing improved system acquisition in an environment of multiple co-existing technologies over a common frequency band are disclosed. In one aspect, at a remote terminal, a power spectral distribution (PSD) of received signals is sequentially measured in contiguous segments of a frequency band of interest. One or more characteristics of the measured PSD is compared to at least one predetermined metric to identify the presence or absence of at least one technology type of the received signals in frequency locations across the band. A system acquisition operation is performed in accordance with the identification, such as a tailored scan of channels at locations where a desired technology is identified.
