Samsung patents method to fix signal timing errors in 5G connections
Samsung has filed a patent application for a method that helps electronic devices detect and correct frequency errors in wireless signals. The device uses a specific part of the signal called a preamble to measure timing and energy levels, then adjusts the main data stream to ensure accurate reception.
In the filing’s own words
A method performed by an electronic device is provided. The method includes an operation of acquiring, on the basis of a physical random access channel (PRACH) region, a preamble signal related to signals received via a plurality of antennas, acquiring delay information for the preamble signal, acquiring energy information, acquired through a correlation operation, about the preamble signal, estimating a frequency offset for the preamble signal on the basis of the delay information and the energy information, and compensating for the estimated frequency offset for a received data signal on the basis of a physical uplink shared channel (PUSCH) region.
What exactly they claim (claim 1)
1. An electronic device comprising: a transceiver; memory, comprising one or more storage media, storing instructions; and at least one processor comprising processing circuitry, wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to: obtain, based on a physical random access channel (PRACH) region, a preamble signal related to signals received through a plurality of antennas, obtain delay information on the preamble signal, obtain energy information on the preamble signal obtained through a correlation operation, estimate, based on the delay information and the energy information, a frequency offset related to the preamble signal, and compensate the estimated frequency offset for a data signal received based on a physical uplink shared channel (PUSCH) region.
