Abstract: A method and an apparatus for determining an RBG size are provided. In the method, a network device or a terminal determines an RBG size set, where the RBG size set may include one or more possible RBG sizes; and determines a first RBG size included in the RBG size set. The network device allocates a resource to the terminal by using the determined first RBG size. The terminal determines, based on the determined first RBG size, the resource allocated by the network device to the terminal.

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.
