Abstract:
The present disclosure discloses an uplink detection method and device in a NOMA system. The method includes: performing pilot activation detection on each terminal in a first terminal set corresponding to a NOMA transmission unit block repeatedly until a detection end condition is met, wherein the first terminal set includes terminals that may transmit uplink data on the NOMA transmission unit block; performing channel estimation on each terminal in a second terminal set that determined through the pilot activation detection within each repetition period, wherein the second terminal set includes terminals that have actually transmitted uplink data on the NOMA transmission unit block; and detecting and decoding a data channel of each terminal in the second terminal set within each repetition period.

Claim (Index 20):
The base station according to  claim 19 , wherein in the case that the pilot activation detection is performed on each terminal in the first terminal set corresponding to the NOMA transmission unit block, the processor is further configured to read the programs in the memory, so as to:\n determine an autocorrelation matrix of a pilot signal on each uplink subcarrier of the time-frequency resource of the NOMA transmission unit block; determine an average value of autocorrelation matrices of pilot signals on all uplink subcarriers of the time-frequency resource of the NOMA transmission unit block; determine a maximum eigenvalue and a minimum eigenvalue of the average value; and determine the second terminal set according to the maximum eigenvalue and the minimum eigenvalue.
