Abstract
Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A method comprises determining, at a first device, a first parameter for determination of a sequence group index based on at least one of the following: a second parameter indicating an identity associated with a physical channel between the first device and a second device, a third parameter indicating a scrambling identity, and a fourth parameter indicating a cell identity; determining the sequence group index based on the first parameter; generating, at least based on the sequence group index, a Demodulation Reference Signal (DMRS) sequence to be transmitted to the second device; and transmitting the generated DMRS sequence to the second device over the physical channel. Embodiments of the present disclosure can enable DMRS transmission with low Peak to Average Power Ratio (PAPR) and high flexibility.
