Abstract: This application relates to the field of communication technologies, and provides a reference signal resource determining method and an apparatus. In a multi-point transmission mode, uplink sending occurs between reference signals from different transmission points in a CSI measurement process; consequently, phases are discontinuous on the reference signals received by a terminal device from the different transmission points. First, configuration information of a reference signal resource set is obtained to determine K reference signal resources, where K is a positive integer, and slots in which at least two of the K reference signal resources are located are different slots, or there is an uplink symbol in a first interval of at least two of the K reference signal resources.

Abstract: Example reference signal transmission methods and apparatus are described. In one example method, a base station divides a transmission bandwidth into a plurality of frequency domain units, and sends reference signal sending configuration information to a terminal. The terminal transmits a reference signal on one or more frequency domain units. The one or more frequency domain units and another frequency domain unit form a part of the transmission bandwidth supported by the base station. The terminal sends the reference signal on the one or more frequency domain units to the base station based on the reference signal sending configuration information.
