Abstract: In a signal transmission method, a user equipment receives a first signal from a wireless network device; and the user equipment determines spatial information of a to-be-transmitted second signal based on the first signal, and transmits the to-be-transmitted second signal by using the spatial information. An uplink transmit beam is determined by using related information of a downlink receive beam, so that the UE can efficiently determine spatial information of an uplink signal to be transmitted by the UE.

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.
