METHOD FOR DETERMINING DEMODULATED PILOT SEQUENCE IN UPLINK, TERMINAL, AND UPLINK SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method for determining a demodulated pilot sequence in an uplink.

SOLUTION: The method for determining the demodulated pilot sequence in the uplink includes a step for determining one of a plurality of transmitting antennas in the uplink as a standard transmitting antenna and other transmitting antennas as subordinate transmitting antennas; setting the demodulated pilot sequence with respect to the standard transmitting antenna; establishing a demodulated pilot sequence subordination to each of the standard transmitting antenna and the subordinate transmitting antennas; and setting the demodulated pilot sequence to each of the subordinate transmitting antennas; on the basis of the demodulated pilot sequence to the standard transmission antenna and the demodulated pilot-sequence subordination. Further, a user terminal device and an uplink system are provided to supply a demodulated pilot to a multiple transmission antenna. The method, device and system are applied to an SU-MIMO (single-user multi-input multi-output) transmission and an MU-MIMO (multi-user multi-input multi-output) transmission.
