摘要： A method and apparatus for frequency offset estimation exploits the differences in reference symbol timing for different channels to resolve ambiguities in the frequency offset estimation. Based on the initial frequency offset estimates, a hypothesis table is constructed providing hypothesized frequency offsets for each channel for a plurality of possible offset regions. An error metric for each offset region is calculated based on the difference of the hypothesized frequency offsets. The set of hypothesized frequency offsets that minimize the error metric is selected as the final frequency offset estimates.

摘要： A random access process may be performed with an extended set of random access preambles comprising a standard set and at least one additional set. The use of a preamble from the standard set or the additional set may be used to indicate whether a wireless communication device belongs to a standard class or a non-standard class, allowing a radio access node to provide special treatment to the non-standard class in a random access response.

摘要： Methods and network devices estimate power of signals received from a user equipment in a sector of a cellular network cell using a data signal, which is not a predetermined reference signal. An exemplary method includes (1) saving a data signal received from the user equipment in a first sector of the cellular network cell, (2) acquiring a reference signal that corresponds to the data signal as received in a second sector of the cell and demodulated, and (3) comparing the saved data signal and the reference signal to estimate power of the data signal as received in the first sector.
