Abstract: Sounding reference signal SRS configuration and transmission methods provide more SRS transmission resources, and meet requirements for uplink channel quality measurement and channel estimation in, for example, a short-delay system and a millimeter-wave system. In an SRS configuration method, a base station sends configuration information of an SRS subframe to a terminal in a current cell, to instruct the terminal to send, according to the received configuration information, an SRS in the SRS subframe, where the SRS subframe is an uplink subframe, or is a subframe in which a quantity of uplink symbols is not less than a quantity of downlink symbols; and all uplink symbols in the SRS subframe can be used to carry an SRS.

Abstract: Embodiments of the present invention provide a communication method. A first network device configures power configuration information for each of at least two precoding matrix groups, and sends the power configuration information to a second network device. The power configuration information is used to indicate a power configuration of a corresponding precoding matrix group of the at least two precoding matrix groups, and the at least two precoding matrix groups belong to a same resource used to measure channel state information CSI. When the second network device performs CSI measurement, different power values of different precoding matrix groups can be considered, thereby increasing accuracy of the CSI measurement.
