摘要： Techniques are disclosed for synchronizing frequency among a cluster of coordinated transmission points cooperating in a coherent joint transmission. In some embodiments, one transmission point is set (510) as a reference transmission point for a group of coordinated transmission points. Each of one or more other transmission points in the group receives (530) a specified downlink reference signal from the reference transmission point, measures (540) its frequency offset relative to the reference point, and compensates (550) the frequency offset in baseband processing or by a radio adjustment. Which transmission point acts as the reference transmission point is statically defined, in some embodiments, or dynamically configured, in others. Likewise, which time-frequency resources are used for the reference signal may be statically defined or dynamically configured. In some embodiments, information identifying the reference transmission point and/or specifying the radio resource locations and durations of the reference signal is distributed to the synchronizing transmission points.

摘要： A noisy frequency-domain channel estimate enhancer includes an over-sampler configured to transform the noisy frequency-domain channel estimate into a time-domain channel estimate that is virtually over-sampled by an integer factor m. The over-sampler is connected to a de-interleaver configured to divide the time-domain channel estimate into m de-interleaved sub-vectors. The de-interleaver is connected to a suppressor configured to suppress noisy taps from each de-interleaved sub-vectors to form m noise suppressed sub-vectors. The suppressor is connected to a selector configured to select a noise suppressed sub-vector associated with a highest signal-to-noise ratio. The selector is connected to a discrete Fourier transformer configured to transform the selected noise suppressed sub-vector into a noise suppressed preliminary frequency-domain channel estimate. The discrete Fourier transformer is connected to a phase-shifter configured to phase-adjust the taps of the noise suppressed preliminary frequency-domain channel estimate to form an enhanced frequency-domain channel estimate.
