Abstract
A user equipment () is configured to determine a length-6 phase coefficient sequence that is one of multiple unique length-6 phase coefficient sequences in a defined set (). The length-6 phase coefficient sequences in the defined set () include at least: {1, 1, 1, 1, 3, −3} and {−3, 3, −3, 1, 1, −3}; or {−1, −1, −1, 3, −3, −1} and either {3, −3, 3, −1, 3, 3} or {1, 3, 1, −1, −1, 3}. The user equipment () is also configured to generate a quadrature phase shift keying, QPSK-based sequence that comprises a sequence of QPSK symbols whose respective phases are based on the determined phase coefficient sequence. The user equipment () is further configured to generate a reference signal () using the generated QPSK-based sequence, and transmit the generated reference signal () to a network node () in a wireless communication system ().
