Abstract: Methods and apparatus are provided for wireless communication in which a downlink control information (DCI) is transmitted in a physical downlink control channel (PDCCH) in a first bandwidth part (BWP). A UE is responsible for determining a starting resource block (RB) for a data transmission allocated by the DCI based on a value of a frequency domain resource allocation field in the DCI, a reference RB, and a reference size of a second BWP. The data transmission can then be transmitted, in the case of, for example, PUSCH, by a UE or received, in the case of, for example, PDSCH.

Abstract: This application discloses a resource mapping method and an apparatus. The method includes the following steps: receiving, by user equipment, a first resource message sent by a base station, where the first resource message includes a transmission time unit and an offset value corresponding to the transmission time unit; and determining, by the user equipment, a time-frequency resource location of a physical channel or a physical signal in the transmission time unit based on the transmission time unit and the offset value. The technical solutions provided in this application have an advantage of avoiding interference between two carriers.
