Abstract: Embodiments of this application provide a signal transmission method and apparatus. The method includes: receiving, by a terminal device, configuration information sent by a network device, where the configuration information is used to instruct the terminal device to send a reference signal, and a resource used to transmit the reference signal is determined based on a public cell identity of a cell to which the terminal device belongs; and sending, by the terminal device, the reference signal based on the configuration information by using the resource. According to the signal transmission method and apparatus in the embodiments of this application, an existing reference signal can be used to perform interference/channel measurement between terminal devices, so that a terminal device on a receiving side can distinguish between interference cells while reference signal utilization is improved.

Abstract: Embodiments of the present invention provide a control channel resource indication method, user equipment, and a network device. The method includes: sending, by user equipment, a preamble signal sequence; receiving, by the user equipment, higher layer signaling corresponding to the preamble signal sequence, where the higher layer signaling is indicated by downlink control information carried in common search space, and a time-frequency resource detected by the user equipment when determining a control channel includes the common search space and user equipment-dedicated search space; and determining, by the user equipment, frequency domain resource location information of the user equipment-dedicated search space based on the higher layer signaling, where the frequency domain resource location information includes a quantity of frequency domain resource units occupied by the user equipment-dedicated search space in frequency domain and a location of the frequency domain resource unit.

Abstract: A resource determining method is provided. The method includes: determining a time domain position and a resource unit type of a first time domain resource unit based on first configuration information; determining a time domain position of a second time domain resource unit based on the time domain position of the first time domain resource unit, where the time domain position of the second time domain resource unit is at a time domain position which is different from the time domain position of the first time domain resource unit and is within a preset time period; and receiving second configuration information from a network-side device, and determining a resource unit type of the second time domain resource unit based on the second configuration information. Thus, subframe types of various subframes in D-TDD can be determined.
