REFERENCE SIGNAL MANAGEMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18516171 titled 'REFERENCE SIGNAL MANAGEMENT

Simplified Explanation

The present invention describes an apparatus that selects a reference signal sequence, extends the signal spectrally, and performs various operations based on the number of resource blocks located outside a frequency interval. Specifically, when the number of resource blocks is odd, the apparatus either symmetrically extends a cyclically shifted version of the selected reference signal sequence or asymmetrically extends the selected reference signal sequence without shifting it. The extended reference signal sequence is then mapped to resource blocks in and outside the frequency interval, followed by spectral shaping of a second signal comprising these resource blocks. Finally, the apparatus transmits the second signal in the uplink direction.

  • Apparatus selects a reference signal sequence
  • Determines number of resource blocks outside a frequency interval
  • Extends the signal spectrally
  • Performs operations based on odd or even number of resource blocks
  • Maps extended reference signal sequence to resource blocks
  • Performs spectral shaping of the second signal
  • Transmits the second signal in uplink direction
