Title:
REFERENCE SIGNAL TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2020/087473
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to methods, devices and computer readable media for Reference Signal (RS) transmission. A method for communication comprises determining one or more RS ports for RS transmission, the one or more RS ports being included in one or more RS groups. The method further comprises determining a plurality of parameters for generating a RS sequence specific to a RS group in the one or more RS groups, the RS group including at least one of the one or more RS ports. The method further comprises generating the RS sequence based on the plurality of parameters. In addition, the method further comprises transmitting the generated RS sequence over the at least one of the one or more RS ports. The embodiments of the present disclosure can solve the PAPR issue caused by mapping a same RS sequence to antenna ports across RS port groups.
