METHOD AND APPARATUS FOR GENERATING A LONG TRAINING SEQUENCE AND SENDING A SIGNAL

摘要

The present disclosure discloses a method and an apparatus for generating a long training sequence and sending a signal, and belongs to the field of wireless communications. The method includes: obtaining a plurality of long training sequences according to a system parameter and a preset sequence construction formula, wherein the plurality of long training sequences include a plurality of basic training sequences and a plurality of shift training sequences obtained according to cyclic shift of the basic training sequences; and configuring a mapping rule between a terminal device and a long training sequence, for enabling the terminal device to select a long training sequence according to the mapping rule as a long training sequence for sending a signal. By adopting the present disclosure, energy consumption of the receiving end may be reduced and accuracy of channel estimation may be improved.
