Abstract
This application discloses a reference signal transmission method and an apparatus. A network node sends reference signals by mapping the reference signals to at least one resource unit, where the at least one resource unit includes a plurality of sub-resource units; and the network node receives, from the terminal, measurement information related to part of the plurality of sub-resource units. The terminal selects, based on configuration information of the reference signals, part of the measurement information to report, so that a quantity of channel resources occupied by the measurement information is reduced.
Claims16
A reference signal transmission method, comprising:
- sending, by a network node, configuration information of reference signals to a terminal device, wherein the configuration information includes information of a resource unit for transmitting the reference signals and a resource unit type, wherein the resource unit comprises a plurality of sub-resource units, and the resource unit type indicates that the reference signals mapped to the plurality of sub-resource units of the resource unit have a different reference signal characteristic;
- sending, by the network node, the reference signals by mapping the reference signals to the plurality of sub-resource units to the terminal device;
- and
- receiving, by the network node from the terminal device, measurement information related to part of the plurality of sub-resource units, wherein the measurement information comprises an sub-resource unit index and a measurement value corresponding to the sub-resource unit index.
