摘要： A method for channel estimation includes receiving data at a number of frequency intervals in a frequency band over a number of first time intervals. A first set of channel estimates is determined for each pilot symbol within the data over a second time interval comprising at least one first time interval, and time-direction interpolation is performed to determine a second set of channel estimates for a number of data portions in a frequency interval using the first set of channel estimates. The frequency interval comprises a data portion comprising a pilot symbol. Frequency-direction interpolation is performed to determine a third set of channel estimates for each first time interval. The time-direction interpolation and the frequency-direction interpolation can be performed in reverse order with the channel estimates generated by the frequency-direction interpolation being used as inputs for time-direction interpolation.

摘要： Aspects of the present application include using adaptive measurement intervals to improve RSSI scan accuracy. A method may involve determining a first power value in respect of a first measurement time interval, determining whether or not the first power value meets at least one criterion, when the first power value does not meet the at least one criterion, determining at least one additional power value, selecting at least one power value from a set of power values that have been determined, the set including the first power value and the at least one additional power value, and determining the power value for use in cell selection or cell re-selection based on the selected at least one power value. The methods may be applied to any cell selection or re-selection scheme for which an adaptive measurement interval may be beneficial.

摘要： Described herein are methods and devices for use in telecommunication cell selection and re-selection for which there may be multiple different sizes of transmission bandwidth configurations in a telecommunications operating band. For each of a plurality of channel hypotheses, in which each channel hypothesis has a hypothetical occupied portion and a hypothetical guard band portion, a respective metric is calculated based on a power value for the hypothetical occupied portion and a power value for the hypothetical guard band portion. Based on the metrics determined for the plurality of channel hypotheses, at least one channel hypothesis is selected for further processing for cell selection or re-selection. The metric is calculated by determining a difference between the power value for the hypothetical occupied portion and the power value for the hypothetical guard band portion.

摘要： There are disclosed systems and methods that dynamically vary the word length of data being transmitted through a digital interface. In one embodiment, the method comprises: (i) obtaining at least one parameter indicative of a quality of a signal; (ii) if the at least one parameter indicates that the quality of the signal is above a threshold, then transmitting the data as a number of digital words at a first predetermined word length; (ii) if the at least one parameter indicates that the quality of the signal is below the threshold, then transmitting the data as a number of digital words at a second predetermined word length. The second predetermined word length is different from the first predetermined word length.

摘要： Systems and methods can be implemented on a wireless device and base stations to facilitate uplink synchronization. The wireless device can transmit a random access preamble to at least one base station serving the wireless device to initiate a random access procedure. The wireless device can identify a signal propagation time associated with the position of the wireless device and the position of the at least one base station serving the wireless device. The wireless device can also identify a positive time advance based on the identified signal propagation time for transmitting the random access preamble. Further, the wireless device can transmit the random access preamble to the at least one base station based on the identified time advance for random access.

摘要： An apparatus has a first communication module and a second communication module. The first communication module is compatible with a first wireless communication technology, and the second communication module is compatible with a second wireless communication technology that differs from the first wireless communication technology. Transmissions by the second communication module may contribute to interference at the first communication module. The first communication module refrains from advertising support for any data rate that is not expected to be sufficiently resilient in the face of interference caused by transmissions from the second communication module.
