Title:
REFERENCE SIGNAL SENDING METHOD, RECEIVING METHOD, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/051416
Kind Code:
A1
Abstract:
A reference signal sending method, receiving method, apparatus and system provided in embodiments of the present application. A terminal receives configuration information of a first reference signal from a network device; on the basis of the configuration information, an uplink signal comprising uplink data and the first reference signal is sent to a network device within at least two time units; and in two adjacent time units, the first reference signal is borne on the last M symbols in symbols in which the uplink signal is within the previous time unit, and the first reference signal is borne on the first N symbols in symbols in which the uplink signal is within the latter time unit, so that a time interval between the first reference signal in the previous time unit and the first reference signal in the latter time unit is small, and thus a phase change due to a channel change can be reduced as much as possible, and a probability that the network device correctly determines whether a phase jump occurs between different time units is improved, thereby improving the accuracy of determining whether cross-time unit joint channel estimation can be performed across time units.
