Title: METHODS AND APPARATUSES FOR REFERENCE SIGNAL TRANSMISSION AND RECEIVING
Abstract:
Embodiments of the present disclosure relate to methods and apparatuses for reference signal transmission and receiving in a wireless communication system. A common reference signal sequence is generated based on a frequency range configuration at network side, the common reference signal sequence being shared by at least some of terminal devices respectively allocated with their own reference signal transmission configurations. The common reference signal sequence and sequence configuration information is transmitted to a terminal device, the sequence configuration information indicating a parameter by which a reference signal sequence transmitted for the terminal device can be obtained. With embodiments of the present disclosure, a reference signal sequence solution with a low complexity is proposed for the wireless communication system (especially for new radio access system) with dynamic bandwidth allocation and/or configurable reference signal pattern, wherein only one common reference signal sequence is generated and shared by at least some of terminal devices, irrespective of reference signal transmission configurations like bandwidth allocation and/or reference signal pattern configuration.
