Title:
METHOD AND DEVICE FOR PILOT SEQUENCE TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2019/047060
Kind Code:
A1
Abstract:
Methods, systems, and devices are disclosed for digital wireless communication, and more specifically, for the use of pilot sequences that improves performance of channel estimation. In one exemplary aspect, a method of wireless communication performed by a communication node is disclosed. The method includes determining, using a first index, a mask sequence from a plurality of pre-determined mask sequences, wherein the plurality of pre-determined mask sequences is determined based on permutations of values 1, -1, i, and -i or permutations of values 1+i, or 1-i, or -1+i, or -1-i.; determining a Walsh sequence using a second index, wherein the Wash sequence has a same length as the mask sequence; generating a pilot sequence by combining the mask sequence and the Walsh sequence; and performing a wireless transmission using the pilot sequence.
